FIG.1Ais a front view of a structure of an electronic device according to an embodiment of this application; andFIG.1Bis a rear view of a structure of an electronic device according to an embodiment of this application. Referring toFIG.1AandFIG.1B, an electronic device100provided in an embodiment of this application includes a housing and a display area103disposed on the housing, where the display area103is provided with a display, and the display may be a bendable display or a flexible display. The housing includes a first frame101and a second frame102. A rotation shaft is disposed between the two frames, and ends that are of two adjacent frames and that are close to the rotation shaft may rotate around the rotation shaft located between the two frames, so that the ends that are of the two frames and that are away from the rotation shaft are relatively close to each other or relatively far away from each other, and the electronic device100may correspondingly present different states such as a folded state or an unfolded state.

The display on the display area103covers surfaces of the two frames, and may correspondingly present a state such as a folded state or an unfolded state as positions of the two frames change. When the first frame101and the second frame102are unfolded, the first frame101and the second frame102are disposed side by side on a same plane. In this case, the display (the display area103) that covers surfaces of the two frames is unfolded to form a large display surface, and the display surface may be used as a separate display. A state shown inFIG.1Bis a state formed after the structure inFIG.1Ais turned upside down in a horizontal direction.

It should be noted that a quantity of the frames of the electronic device100may be two or more, and when the quantity of the frames is more than two, adjacent frames may rotate around mutually parallel rotation shafts to form a multi-layer folded structure, or may expand to obtain a larger display area. In the embodiments of this application, the electronic device100is mainly described by using two frames as an example.

FIG.2Ais a rear view of a display of an electronic device according to an embodiment of this application;FIG.2Bis a rear perspective view of an electronic device according to an embodiment of this application; andFIG.2Cis an overall perspective view of an electronic device according to an embodiment of this application. Referring toFIG.2A,FIG.2B, andFIG.2C, the electronic device100includes components in the electronic device, such as a processor, a memory, a camera assembly, a screen chip110, a screen outlet line120, a flat cable140, and a battery150. For example, components such as the processor, the memory, and the camera assembly may be disposed in the first frame101(at a position that is corresponding to the first frame101and that is not marked with a reference sign on the left side as shown inFIG.2B). The second frame102may be configured to carry components such as the screen chip110, the screen outlet line120, the flat cable140, and the battery150.

The screen chip110, that is, a screen integrated circuit (IC), is a chip configured to drive the display to turn on. The screen chip is made of a fragile material, which is usually glass. The screen chip is fragile after being hit. Therefore, when the screen chip is disposed in the electronic device, a specific avoidance space needs to be reserved between the screen chip and another internal component.

In some embodiments, one screen chip is disposed in the electronic device, so as to turn on the display. However, to improve efficiency of turning on the display, alternatively, two screen chips may be disposed in the electronic device. For example, the two screen chips may be sequentially arranged in a length direction of the device (for example, for an electronic device with a foldable screen, it may be the length direction when the screen is folded).

A screen outlet line120, that is, a screen COP (chip on pi), is a circuit board formed based on a flexible screen encapsulation process.

The flat cable140, also referred to as a flexible printed circuit (FPC), is used for data transmission in a moving component and a moving area. In the field of electronic devices, the FPC is a data cable connected to the display on a handset board. The flat cable can be moved, bent, and twisted without damage to a conductor, and can conform to different shapes and special package sizes.

FIG.3is a partial sectional view of a cross section A-A inFIG.2Caccording to an embodiment of this application. Referring toFIG.3, a display on the display area103covers the first frame101and the second frame102, and in a direction from the display area103to the back of the device, a gasket121is laminated to a lower part of the display, a screen outlet line120is provided at one end of the display, and the screen outlet line120is connected to one end of the display. The screen outlet line120is bent along a direction from the display to the back of the device, and a large surface (not shown in the figure) of the screen outlet line120is laminated to a lower surface of the gasket121, that is, a large surface of the screen outlet line120is evenly distributed on a surface that is of the gasket121and that is close to the back of the device, and the gasket121is configured to support the large surface. The screen chip110is laminated to a lower part of a large surface of the screen outlet line120, and the screen chip110is located between the middle frame131and the large surface of the screen outlet line120. The large surface of the screen outlet line120is not shown in the figure. In a direction from the display area103to the back of the device, an internal structure of the electronic device is sequentially as follows: the display, the gasket121, the large surface of a screen outlet line120, the screen chip110, and the middle frame131.

The flat cable140is located between the display and the middle frame131, and the flat cable140is laminated to the lower part of the display, and one end of the flat cable140extends to the large surface of the screen outlet line120, and is laminated to the large surface, which is equivalent to that one end of the flat cable140extends to the gasket121, and the extension end of the flat cable140is laminated to a same side of the large surface as the screen chip110. One end (that is, the extension end) of the flat cable140is connected to the screen outlet line120, and the other end of the flat cable140is connected to the processor. Although both the extension end of the flat cable140and the screen chip110are laminated to the large surface, there is no contact between the extension end of the flat cable140and the screen chip110; and there is a gap between the extension end of the flat cable140and the screen chip110, and a thickness of the extension end of the flat cable140is less than or equal to a thickness of the screen chip110. If the thickness of the extension end of the flat cable140is greater than the thickness of the screen chip110, a higher avoidance space is caused, and the overall thickness increases.

The battery150is disposed on a side that is of the screen chip110and that is away from the screen, that is, the battery150is disposed below the screen chip110. To fasten the battery150, the housing of the electronic device forms the battery compartment130. For example, the battery compartment130may be formed in the second frame102, and the battery150is fastened in the battery compartment130. An opening direction of the battery compartment130faces a side that is away from the screen, so that the battery150and the screen chip110are separated from each other by the bottom of the battery compartment130.

The bottom of the battery compartment130is used as the middle frame131of the electronic device, and the middle frame131may be disposed in parallel with the display. The screen chip110, the screen outlet line120, and the flat cable140are disposed above the middle frame131(the side that is close to the display), and the battery150is disposed below the middle frame131(the side that is away from the display). The middle frame131is not only used to separate components in the electronic device, but also used to improve stability of the housing of the electronic device. When the user uses the electronic device, and a finger touches the display and presses the display, the screen chip110, the screen outlet line120, and the flat cable140move downward, and the three components are all located above the battery150. If the three components move downward, the three components will be in contact with the middle frame131, so that the middle frame131moves downward and is in contact with the battery150, causing the battery150to wear out. Therefore, the battery150is separated from the three components by using the middle frame131, to prevent the three components from continuously moving downward and being in contact with the battery150, so as to protect the battery150.

When components are arranged inside the electronic device, to ensure safety of the components, in addition to necessary contact for data transmission, other components without data transmission are not in direct contact, but a specific safety gap needs to be reserved. For example, a safety gap needs to be reserved between the middle frame131and the large surface (equivalent to the position of the gasket121) of the screen outlet line120, a safety gap needs to be reserved between the middle frame131and the flat cable140, and a safety gap needs to be reserved between the middle frame131and the screen chip110. In some embodiments, the safety gap to be reserved between the middle frame131and the large surface of the screen outlet line120or the flat cable140may be about 0.1 mm.

A thickness of the screen chip110is about 0.25-0.3 mm. The screen chip110forms a protruding structure relative to the large surface (equivalent to the position of the gasket121) of the screen outlet line120, that is, a thickness of the protruding structure is about 0.25-0.3 mm. When the user presses the display, the screen chip110moves downward and touches the middle frame131, and the screen chip110is made of a glass material, and is fragile after being hit, causing the screen chip110to wear out. Therefore, to protect the screen chip110from wearing out, a specific avoidance space needs to be reserved between the screen chip110and the middle frame. In some embodiments, while ensuring an avoidance effect, a distance of at least about 0.25 mm needs to be reserved for the avoidance space, that is, an avoidance distance of the screen chip110is at least about 0.25 mm.

It can be learned that, to avoid the protruding screen chip110, the middle frame131(that is, the bottom of the battery compartment130) needs to be moved down toward the back of the device as a whole, which causes the overall thickness of the electronic device to increase. To ensure the overall thickness of the electronic device and avoidance of the screen chip110, while ensuring a requirement for the gap between the middle frame131and the screen outlet line120, a relative position between the middle frame131and the screen chip110locally sinks, so that the middle frame131presents a locally sunk groove, where the groove is used to accommodate the screen chip110, and a depth of the groove is less than the thickness of the middle frame131. During avoidance, the protruding structure formed by the screen chip110relative to the large surface of the screen outlet line is located in the groove, and a distance between the screen chip110and the bottom of the groove is greater than the avoidance distance of the screen chip110.

Because the position of the screen chip110is close to the position of the flat cable140, and both the screen chip110and the flat cable140are laminated to the large surface, the groove formed on the middle frame131may also implement avoidance of the flat cable140. The groove on the middle frame131may avoid both the screen chip110and the flat cable140, but the protruding heights of the protruding structures that are formed by the screen chip110and the flat cable140relative to the screen outlet line120are different. Therefore, the structure of the groove may be in an irregular form, provided that avoidance of the screen chip110and the flat cable140may be implemented.

Based on a reliability requirement of the electronic device, a gap between the screen chip110and the middle frame131needs to be greater than a gap between the large surface (equivalent to the position of the gasket121) of the screen outlet line120and the middle frame131, so that a depth of the groove disposed on the middle frame131increases. Based on the avoidance solution shown inFIG.3, to avoid the screen chip110, the groove is disposed in a local position corresponding to the screen chip110on the middle frame131, the middle frame131has a minimum thickness at a position at which the groove is disposed, and the minimum thickness is less than the overall thickness at which the groove is not disposed on the middle frame131. However, even if the groove is disposed on the middle frame131, original reliability of the middle frame131needs to be ensured. Therefore, an overall thickness of the middle frame131needs to be increased, so that a remaining thickness obtained after the groove is locally disposed on the middle frame131can still meet the reliability requirement.

For example, in the foregoing avoidance solution, the overall thickness H1of the middle frame131needs to be higher than 0.65 mm, the depth of the groove formed on the middle frame131through local sinking needs to be at least greater than 0.25 mm, and the minimum thickness of the position that is of the middle frame131and at which the groove is disposed needs to be at least 0.4 mm.

To further reduce the overall thickness of the electronic device, in the electronic device provided in another embodiment of this application, internal components of the electronic device are improved. That is, as shown inFIG.4, a hole is provided at a position that is at the bottom (that is, the middle frame131) of the battery compartment130and that is opposite to the screen chip110, a middle frame hole132is formed on the middle frame131, the middle frame hole132is a through hole, and a depth of the middle frame hole132is equal to the thickness of the middle frame131. Avoiding the protruding screen chip110by using the middle frame hole132does not cause a thickness of the remaining position of the middle frame131to increase, thereby reducing the overall thickness. On a side close to the screen, a black structure (not marked in the figure) between the large surface of the screen outlet line120and the middle frame131is an adhesive, and the adhesive is used to stick the screen outlet line and the middle frame131together for cushioning and waterproofing.

In some embodiments, the electronic device may be a device with a foldable screen, a tablet computer, or the like. The solution provided in this embodiment of this application may be applicable to a case in which the screen chip becomes a bottleneck of the overall thickness due to a battery disposed below the screen chip or another reason.

FIG.4is a partial sectional view of a cross section A-A when a middle frame hole is provided in a battery compartment according to an embodiment of this application. Referring toFIG.4, in the electronic device, to enable the middle frame131to avoid a protruding screen chip110, a position corresponding to the screen chip110on the middle frame131is hollowed out to form a middle frame hole132. In this case, the position of the middle frame131relative to the screen chip110has no thickness. A relative position between the middle frame131and the large surface of the screen outlet line120is set based on a minimum safety gap. When a distance between the middle frame131and the large surface meets a requirement for a minimum safety gap, the protruding screen chip110is embedded in the middle frame hole132. In this case, the entire screen chip110is in the middle frame hole132, and the screen chip110is accommodated by using a space of the middle frame hole132; a protruding structure formed by the screen chip110relative to the large surface of the screen outlet line is located in the middle frame hole132, and a protruding height of the protruding structure is less than a thickness of the middle frame hole132; and a distance between the screen chip110and the battery150is greater than an avoidance distance of the screen chip110.

In this case, even if the user presses the display to drive the screen chip110to move downward, the screen chip110is not in contact with the middle frame131, thereby preventing the screen chip110from wearing out. In addition, at a position in which the bottom of the battery compartment130overlaps the screen chip110, a wall thickness of the middle frame131is cut off, and the screen chip110does not need to be avoided in the manner shown inFIG.3, thereby further reducing a thickness of the middle frame, and making full use of an internal space of the electronic device.

In this embodiment of this application, to reduce the overall thickness, the overall thickness of the middle frame131of the electronic device needs to be as thin as possible while ensuring reliability of the electronic device. For example, the overall thickness of the middle frame131should be set to at least 0.4 mm. According to the electronic device provided in this embodiment, the protruding screen chip110is avoided by providing the middle frame hole132on the middle frame131, and the screen chip110does not need to be accommodated by using a groove. Therefore, the middle frame131does not need to relatively thick, that is, the thickness of the middle frame131adjacent to the screen or the thickness of the middle frame131in contact with the battery150(for example, the bottom of the battery compartment130) is set to a minimum wall thickness that can ensure reliability. For example, the thickness of the middle frame131adjacent to the screen may be set to 0.4 mm, or the thickness of the middle frame131in contact with the battery may be set to 0.4 mm.

In the avoidance solution shown inFIG.3, the overall thickness H1of the middle frame131is greater than 0.65 mm; while in the solution provided in this embodiment of this application shown inFIG.4, the overall thickness H2of the middle frame131may be set to a minimum wall thickness of 0.4 mm. Therefore, it can be learned from the comparison that the thickness of the middle frame131shown inFIG.4in this embodiment of this application is less than the thickness of the middle frame131shown inFIG.3. Therefore, the overall thickness of the electronic device can be further reduced by reducing the thickness of the middle frame131.

In some embodiments, a size of the middle frame hole132needs to fit a size of the screen chip110. From a perspective of reliability, the size of the middle frame hole132should not be too large. From a perspective of avoiding the screen chip110, the size of the middle frame hole132should not be too small.

FIG.5Ais a rear perspective view when a middle frame hole is provided in a battery compartment according to an embodiment of this application; andFIG.5Bis a rear perspective view when a screen chip is accommodated by a middle frame hole according to an embodiment of this application. Referring toFIG.5A, because the screen chip110is of an elongated structure in a length direction of the device, to ensure that the middle frame hole132provided on the middle frame131can easily accommodate the screen chip110, the middle frame hole132may also be of an elongated structure in the length direction of the device, such as a rectangular structure. In another embodiment, the middle frame hole132may alternatively be in another shape, such as a rounded rectangular shape, an oval shape, or the like.

Referring toFIG.5B, when the screen chip110is accommodated by the middle frame hole132, the screen chip110may be embedded in the middle frame hole132because the middle frame hole132corresponds to a position of the screen chip110relative to the middle frame131.

To ensure that space of the middle frame hole132can accommodate the screen chip110and that reliability of the middle frame hole132is not affected, a size of the middle frame hole132is slightly larger than a size of the screen chip110. For example, the middle frame hole132is offset from the screen chip110by a specific distance, and the offset distance may be set to about 1 mm. For example, the offset distance is greater than 1 mm. From a perspective of the overall offset size, a length of the middle frame hole132is greater than a length of the screen chip110by about 2 mm, and a width of the middle frame hole132is greater than a width of the screen chip110by about 2 mm.

Referring toFIG.4again, because the extension end of the flat cable140is laminated to the large surface (equivalent to the position of the gasket121) of the screen outlet line120, the extension end of the flat cable140is also higher than the large surface to form a protruding structure. The thickness of the extension end of the flat cable140is less than or equal to the thickness of the screen chip110(that is, a protruding height relative to the large surface of a screen outlet line), so as to prevent a larger avoidance space from being generated at the middle frame131, thereby avoiding a greater overall thickness.

In this case, the middle frame hole132needs to avoid the extension end of the flat cable140while avoiding the screen chip110. Therefore, the extension end of the flat cable140is located in the middle frame hole132, and the size of the middle frame hole132is greater than a total size that is enclosed by the screen chip110and the extension end of the flat cable140, that is, the size of the middle frame hole132is greater than an outer size of an overlapping part between the screen chip110+the extension end of the flat cable and the large surface of the screen outlet line120. In a width direction of the electronic device, a start position (a) on one side of the middle frame hole132may be opposite to a start position at which the extension end is generated by the flat cable140, and another end position (b) on the other side of the middle frame hole132may be a position corresponding to a minimum distance required when the middle frame hole132is offset from the screen chip110.

According to the electronic device provided in this embodiment of this application, because of a relative position relationship between and structural characteristics of the screen chip110and the screen outlet line120, the screen chip110forms a protruding structure relative to the large surface of the screen outlet line120. While it is ensured that the middle frame131and the large surface meet a requirement for a minimum safety gap, to avoid contact between the middle frame131and the screen chip110, the middle frame131needs to avoid the screen chip110. In an avoidance manner in this embodiment of this application, the middle frame hole132is disposed at a position of the middle frame131relative to the screen chip110, and the middle frame hole132accommodates the screen chip110, so as to prevent the screen chip110from moving downward and being in contact with the middle frame131to cause damage because the user presses the display. In addition, when the screen chip110is avoided by the middle frame hole132, only a minimum wall thickness that meets a reliability requirement needs to be set. It can be learned that, in this avoidance manner, the internal space of the electronic device can be fully used, and the wall thickness of the middle frame131can be reduced while the screen chip110is avoided, thereby further reducing the overall thickness of the electronic device.

In some embodiments, to avoid the screen chip110, the middle frame hole132is disposed in a hollow-out manner at a relative position at the bottom (the middle frame131) of the battery compartment130. In this case, the screen chip110is not separated from the battery150by the middle frame131. In this case, if the user presses the display hard, the screen chip110sinks due to applied force. Because the position of the screen chip110is no longer blocked by the middle frame110, the screen chip110may sink excessively and be in contact with the battery150.

When the screen chip110is in contact with the battery150, the screen chip110may be damaged. In addition, if the screen chip110is broken, debris generated by the screen chip110may pierce the battery150, which affects use of the battery150. In addition, the middle frame hole132provided on the middle frame131may reduce reliability of the middle frame131. Therefore, from a perspective of avoiding significant deformation of and damage to the screen chip110and protecting the battery150, a reinforcement member160may be disposed at the position of the middle frame hole132, the reinforcement member160is located between the screen chip110and the battery150, and the reinforcement member160is fastened around the middle frame hole. The reinforcement member160is used for supporting and positioning, so as to improve reliability of the middle frame131and avoid significant deformation of the screen chip110due to applied force. The reinforcement member160prevents the screen chip110from continuously sinking, to avoid damage caused by contact between the screen chip110and the battery150, and prevent the battery150from being damaged by the screen chip110, so as to avoid a risk.

FIG.6Ais a schematic diagram of a structure when a reinforcement member is disposed at a position of a middle frame hole according to an embodiment of this application; andFIG.6Bis a sectional view of a reinforcement member according to an embodiment of this application. Referring toFIG.6AandFIG.6B, on the basis of the solution for reducing the overall thickness of the electronic device provided in the foregoing embodiment, the reinforcement member160is disposed at the position of the middle frame hole132, and the reinforcement member160includes a bottom edge161, a skirt edge162, and a middle edge163. The bottom edge161is of a solid structure, and both the skirt edge162and the middle edge163are of a hollow annular structure. For example, a material of the reinforcement member160may be a steel material, so as to ensure reliability.

The skirt edge162surrounds the bottom edge161by using the middle edge163. A plane on which the bottom edge161is located and a plane on which the skirt edge162is located are parallel but not overlapped. That is, after being connected by using the middle edge163, the plane on which the bottom edge161is located and the plane on which the skirt edge162is located are spaced by a specific distance in a parallel direction, so that a cross section of the reinforcement member160is of a groove structure, where the groove structure is used to accommodate the screen chip110, and a depth of the groove structure is greater than an avoidance distance of the screen chip110.

The middle edge163may be separately connected to the bottom edge161and the skirt edge162in a vertical state. In this case, the planes on which two adjacent edges of the reinforcement member160are located are perpendicular to each other, and a size of the bottom of a groove formed by the reinforcement member160is the same as a size of an opening. The middle edge163may alternatively be connected to both the bottom edge161and the skirt edge162in an inclined state. In this case, the planes on which two adjacent edges of the reinforcement member160are located are not perpendicular to each other, and a size from the bottom of a groove formed by the reinforcement member160to an opening gradually increases, as shown inFIG.6B.

During mounting of the reinforcement member160, the reinforcement member160is mounted in the middle frame hole132in a concave state with the bottom edge161at the bottom and the skirt edge162at the top, so that the skirt edge162is fastened to the middle frame131around the middle frame hole132, and the skirt edge162is located between the middle frame131and the large surface of the screen outlet line120. To avoid the screen chip110while improving reliability of the middle frame131, the groove formed by the reinforcement member160accommodates the screen chip110. As shown inFIG.6A, the skirt edge162of the reinforcement member160is higher than the bottom edge161, the bottom edge161is close to the battery150, and the skirt edge162is close to the position of the large surface of the screen outlet line120(equivalent to the position of the gasket121).

The bottom edge161of the reinforcement member160is located on a side that is of the middle frame hole132and that is away from the screen chip110, that is, the side that is close to the battery150, and the distance between the bottom edge161and the screen chip110is greater than the avoidance distance of the screen chip110, that is, a depth of the groove formed by the reinforcement member160is greater than the avoidance distance of the screen chip110. Therefore, the reinforcement member160is fastened to the middle frame131, so that reliability of the middle frame131can be improved, and the screen chip110can be avoided.

The screen chip110is separated from the battery150by using the bottom edge161of the reinforcement member160. If the screen chip110significantly deforms when the user presses the display, the bottom edge161of the reinforcement member160may prevent the screen chip110from continuously sinking, so as to avoid contact with the battery150. Even if the screen chip110is damaged because of contact with the bottom edge161, the reinforcement member160may hold fragments, to prevent the fragments from being in contact with the battery150, thereby protecting the battery150.

FIG.7is a rear perspective view when a reinforcement member is disposed at a position of a middle frame hole according to an embodiment of this application. Referring toFIG.7, a middle frame hole132is disposed at a position that is corresponding to the screen chip110and that is at the bottom (a middle frame131) of the battery compartment130, and the reinforcement member160is disposed at the position of the middle frame hole132. From a perspective of the rear perspective view, the middle frame hole132passes through the bottom edge161of the reinforcement member160.

The dashed-line box in the left structure shown inFIG.7is a boundary of the reinforcement member160, that is, a boundary position of the skirt edge162. A complete structure obtained after the reinforcement member160is taken out from the electronic device is shown by a right structure shown inFIG.7. The reinforcement member160is a rounded rectangular structure with a protruding center, and a position of the protruding center is corresponding to a protruding structure of the screen chip110, so as to implement an effect of accommodating the screen chip110by a protruding part of the reinforcement member160.

An overall thickness of the reinforcement member160is less than a wall thickness of the middle frame131, that is, a vertical distance from the bottom edge161to the skirt edge162is less than the wall thickness of the middle frame131, which is equivalent to that a vertical height of the middle edge163is less than the wall thickness of the middle frame131. A distance between the bottom edge161and the battery150may be greater than or equal to a distance between the battery150and a side that is of the middle frame131and that is close to the battery150, so that when the reinforcement member160is fastened on the middle frame131, the middle frame hole132passes through the bottom edge161, and the bottom of the middle frame131is not exposed, where the bottom of the middle frame131is the side that is close to the battery150. In this case, the bottom edge161is separated from the bottom of the middle frame131by a specific distance, which can prevent the bottom edge161from being in contact with the battery150. For example, the distance between the bottom edge161and the bottom of the middle frame131may be set to 0.1-0.15 mm.

In some embodiments, the skirt edge162is fastened on the middle frame131, and the skirt edge162is located between the middle frame131and the large surface (equivalent to the position of the gasket121). A minimum safety gap is reserved between the middle frame131and the large surface, and the reinforcement member160needs to have a specific thickness to ensure strength of the reinforcement member160, where the thickness is greater than the minimum safety gap. Therefore, to avoid that when the skirt edge162is fastened between the middle frame131and the large surface, because a gap between the middle frame131and the large surface needs to be increased, the overall thickness of the electronic device increases, a clamping slot133may be disposed at a position in which the skirt edge162is laminated to the middle frame131. The clamping slot133is used to fasten the skirt edge162, the clamping slot133is located around the middle frame hole132and is close to the large surface, and a depth of the clamping slot133is greater than a thickness of the skirt edge162.

FIG.8is a partially enlarged diagram when a clamping slot is disposed on the middle frame according to an embodiment of this application. Referring toFIG.8, the clamping slot133is disposed through sinking at the position that is of the middle frame131and that is close to the middle frame hole132. When the reinforcement member160is disposed, the skirt edge162is laminated to the clamping slot133, so as to fasten the reinforcement member160. For example, the skirt edge162may be laminated to the clamping slot133on the middle frame131through glue dispensing or spot welding or by using an adhesive, or the like, so as to fasten the reinforcement member160to the edge of the middle frame hole132, so that the reinforcement member160is fastened to the middle frame131as a whole.

To avoid that when the skirt edge162of the reinforcement member160is laminated to the clamping slot133, a top of the skirt edge162is exposed beyond a top of the middle frame131, where the top of the middle frame131is a side close to the large surface, consequently, a safety gap between the middle frame131and the large surface increases. If the safety gap between the middle frame131and the large surface increases, the overall thickness of the electronic device increases. Therefore, in this embodiment of this application, a depth H of the clamping slot133is set to be greater than a sum of a thickness of the reinforcement member160and a thickness of the glue dispensing (or spot welding or adhesive) layer, so that the top of the skirt edge162is lower than the top of the middle frame131, so as to ensure that a minimum safety gap is reserved between the middle frame131and the large surface, thereby reducing the overall thickness of the electronic device.

For example, a thickness of the glue dispensing (or spot welding or adhesive) layer between the skirt edge162and the clamping slot133is about 0.1 mm, and the thickness of the skirt edge162is about 0.1 mm. Therefore, the depth H of the clamping slot133is greater than 0.2 mm. A depth tolerance of the clamping slot133may be set to 0.05 mm, and therefore the depth H of the clamping slot133may be 0.25 mm. A purpose of setting the depth tolerance of the clamping slot133is to ensure that the height of the skirt edge162is lower than the height of the middle frame131by 0.05 mm when the skirt edge162is fully accommodated by the clamping slot133on the middle frame131.

A width of the clamping slot133disposed on the middle frame131may match a width of the skirt edge162, provided that the width of the clamping slot133can fully accommodate the skirt edge162, so as to ensure stability of the skirt edge162. For example, if the width of the skirt edge162is about 1-1.5 mm, the width of the clamping slot133may also be set to 1-1.5 mm.

According to the electronic device provided in this embodiment of this application, to reduce the overall thickness of the electronic device, the middle frame hole132is disposed at the position of the middle frame131relative to the screen chip110, the middle frame hole132accommodates the screen chip110, and the middle frame131has a minimum wall thickness. However, in this case, the screen chip110is not separated from the battery150by the middle frame131, and the screen chip110will excessively sink after being stressed and be in contact with the battery150. Therefore, the reinforcement member160is disposed at a position of the middle frame hole132, and the reinforcement member160is used for supporting and positioning, so as to improve reliability of the middle frame131and prevent the screen chip110from continuously sinking, thereby avoiding damage caused by contact between the screen chip110and the battery150and protecting the battery150. In addition, the clamping slot133is disposed at a contact position between the middle frame131and the reinforcement member160, and the skirt edge162of the reinforcement member160is accommodated by using the clamping slot133, so as to avoid that the top of the skirt edge162is exposed beyond the top of the middle frame131. Therefore, the safety gap between the middle frame131and the large surface of the screen outlet line120(equivalent to the position of the gasket121) increases, so as to ensure that a minimum safety gap is reserved between the middle frame131and the large surface of the screen outlet line120, thereby reducing the overall thickness of the electronic device.

FIG.9is a rear perspective view when a reinforcement member is disposed in an electronic device according to an embodiment of this application; andFIG.10is a partial sectional view of a cross section B-B inFIG.9according to an embodiment of this application. In some embodiments, referring toFIG.9andFIG.10, because the extension end of the flat cable140is in contact with the large surface of the screen outlet line120, a contact position between the extension end of the flat cable140and the large surface of the screen outlet line120is a contact area170. If the reinforcement member160is disposed at the position of the middle frame hole132in the electronic device, the contact position between the reinforcement member160and the middle frame131passes through the contact area170that is formed by the extension end of the cable140and the large surface. However, in the contact area170, the flat cable140is higher than the large surface by a height of one layer of the flat cable140, and when the reinforcement member160passes through the contact area170, the flat cable140is also higher than the contact area170by a thickness of one layer of the flat cable140. In this case, a height of a position at which the reinforcement member160passes through the contact area170is higher than a height of a position at which the reinforcement member160does not pass through the contact area170by a thickness of one layer of the flat cable140, and the height herein refers to a height relative to the large surface. To match the extra thickness of the position at which the reinforcement member160passes through the contact area, the accommodating area inside the electronic device is increased in a thickness direction (that is, a direction from the display to the rear housing), thereby affecting the overall thickness of the electronic device.

With reference toFIG.7, when the screen chip110protruding relative to the screen outlet line120is accommodated by using the reinforcement member160, a protruding portion of the reinforcement member160faces the back of the electronic device (facing the battery), and an opening portion of the reinforcement member160faces the front of the electronic device (facing the display). When the reinforcement member160is mounted at the position of the middle frame hole132, a part of the skirt edge162of the reinforcement member160passes through the contact area170that is formed by the extension end of the flat cable140and the large surface of the screen outlet line120. Therefore, the increased height (the thickness of the flat cable140) of the reinforcement member160when the reinforcement member passes through the contact area170may be removed by changing the structural form of the reinforcement member160. For example, if the height of the flat cable140is about 0.1-0.15 mm, the increased height that is of the reinforcement member160when the reinforcement member passes through the contact area170and that needs to be removed is also about 0.1-0.15 mm.

In some embodiments, a part that is of the reinforcement member160and that is above the contact area170is cut off, that is, a part that is of the skirt edge162and that passes through the contact area170is directly cut off, so as to form the reinforcement member160with the notched skirt edge162; and the remaining part of the skirt edge162is fastened to the middle frame131, so as to prevent the overall thickness of the electronic device from being increased due to a local thickness of the reinforcement member160. The thickness of the skirt edge162is usually 0.1 mm. If an area that is of the contact area170and that is adjacent to the reinforcement member160cannot be accommodated after a part of the skirt edge162is cut off, a part of the middle edge163may be further cut off, that is, a part that is of the middle edge163and that is adjacent to the skirt edge may be cut off.

FIG.11Ais a schematic diagram of a structure of a reinforcement member with a notched skirt edge viewed from a protruding side of a bottom edge according to an embodiment of this application; andFIG.11Bis a schematic diagram of a structure of a reinforcement member with a notched skirt edge viewed from a concave side of a bottom edge according to an embodiment of this application. With reference toFIG.9, it can be learned that when the reinforcement member160passes through the contact area170that is formed by the extension end of the flat cable140and the large surface of the screen outlet line120, the protruding part of the reinforcement member160faces the back of the device (that is, faces the battery), and the parts that are of the skirt edge162and that are at the upper and lower left corners of the reinforcement member160are in contact with the contact area170. Therefore, to avoid increasing the thickness of the contact position, the parts that are of the skirt edge162and that are at the upper and lower left corners of the reinforcement member160are cut off, or the parts that are of the skirt edge162and that are at the upper and lower left corners of the reinforcement member160and a part that is of the middle edge163and that is adjacent to the skirt edge are cut off, so as to form a first notch164and a second notch165, as shown inFIG.11A. The state of the reinforcement member160with the notched skirt edge that is shown inFIG.11Ais a protruding state, that is, the bottom edge161is higher than the skirt edge162.

With reference toFIG.6A, it can be learned that when the reinforcement member160with the notched skirt edge is disposed, in a concave structure, at the position of the middle frame hole132, a state of the reinforcement member160with the notched skirt edge is that the bottom edge161is a concave state, that is, the bottom edge161is lower than the skirt edge162, as shown inFIG.11B.

FIG.12Ais a perspective view of a structure of a reinforcement member with a notched skirt edge disposed in a contact area according to an embodiment of this application; andFIG.12Bis an effect diagram of a structure of a reinforcement member with a notched skirt edge disposed in a contact area according to an embodiment of this application. Referring toFIG.12A, a contact area170(a white dashed line frame) is formed by the flat cable140and the screen outlet line120. When the reinforcement member160is disposed at a position of the middle frame hole132so that the protruding screen chip110is accommodated by the reinforcement member160, both the upper and lower left corners of the reinforcement member160pass through the contact area170. In this case, the reinforcement member160presents a protruding state.

To avoid increasing the height of the reinforcement member160passing through the contact area170, which increases the overall thickness, the parts that are of the skirt edge162and that are at the upper and lower left corners of the contact area170may be cut off, that is, a height formed by the contact area170is accommodated by using the formed first notch164and second notch165. Referring toFIG.12B, a height of one end of the contact area170is accommodated by the first notch164of the reinforcement member160, and a height of the other end of the contact area170is accommodated by the second notch165of the reinforcement member160. The two notched parts of the skirt edge162are no longer fastened to the middle frame131, and are in a suspended state, and the remaining part of the skirt edge162is fastened to the middle frame131.

At the positions of the first notch164and the second notch165, the reinforcement member160is not in contact with the contact area170. Therefore, at the positions, the reinforcement member160does not have a thickness higher than one layer of the flat cable140, and therefore the overall thickness of the electronic device is not increased.

In some embodiments, the start point and the end point of the first notch164or the second notch165in the reinforcement member160are determined to ensure that the reinforcement member160is not in contact with the contact area170. For example, a distance between the start point (the end point) and the contact area170may be set to about 1 mm.

In some embodiments, to offset the increased height (the thickness of the flat cable140) when the reinforcement member160passes through the contact area170, so as to avoid increasing the overall thickness of the electronic device, changing the structural form of the reinforcement member160may also be performing local stamping processing on the skirt edge162that is of the reinforcement member160and that passes through the contact area170, so as to form a reinforcement steel sheet with a skirt edge of unequal heights. No component is designed to be disposed between the locally stamped skirt edge and the middle frame131, and glue dispensing processing is not performed at this position, which can save glue dispensing space of the position and avoid increasing the height of the position.

FIG.13Ais a schematic diagram of a structure of a reinforcement member with a skirt edge of unequal heights viewed from a protruding side of a bottom edge according to an embodiment of this application; andFIG.13Bis a schematic diagram of a structure of a reinforcement member with a skirt edge of unequal heights viewed from a concave side of a bottom edge according to an embodiment of this application. With reference toFIG.9, it can be learned that when the reinforcement member160passes through a contact area170that is formed by the extension end of the flat cable140and the large surface of the screen outlet line120, a protruding part of the reinforcement member160faces the back of the device, and the parts that are of the skirt edge162and that are at the upper and lower left corners of the reinforcement member160are in contact with the contact area170. Therefore, to avoid increasing the height of the contact position, local stamping processing is performed on the parts that are of the skirt edge162and that are at the upper and lower left corners of the reinforcement member160, so as to form a first stamping area166and a second stamping area167, as shown inFIG.13A. A state of the reinforcement member160with a skirt edge of unequal heights shown inFIG.13Ais a protruding state, that is, the bottom edge161is higher than the skirt edge162.

As shown in a cross section C inFIG.13A, in the structure of the reinforcement member with a skirt edge of unequal heights, the first stamping area166and the second stamping area167are closer to the bottom edge161than the skirt edge162, that is, a vertical distance between the first stamping area166and the bottom edge161and a vertical distance between the second stamping area167and the bottom edge are both less than a vertical distance between the skirt edge162and the bottom edge161.

With reference toFIG.6A, it can be learned that when the reinforcement member160with a skirt edge of unequal heights is disposed, in a concave structure, at the position of the middle frame hole132, a state of the reinforcement member160with a skirt edge of unequal heights is a concave state, that is, the bottom edge161is lower than the skirt edge162, as shown inFIG.13B.

FIG.14is a side view of a reinforcement member with a skirt edge of unequal heights shown inFIG.13Aaccording to an embodiment of this application. Referring toFIG.14, when the structural form of the reinforcement member160is changed through local stamping, a part that is of the skirt edge162of the reinforcement member160and that may be easily in contact with the contact area170is locally raised to form a stamping area. Because the parts that are of the skirt edge of the reinforcement member160and that pass through the contact area170are located at the upper and lower left corners (that the reinforcement member is in a protruding state is used as an example), local stamping processing may be separately performed on the parts that are of the skirt edge162and that are at the upper and lower left corners of the reinforcement member160, so that the parts that are of the skirt edge162and that are at the two positions are locally raised, so as to form the first stamping area166and the second stamping area167.

The first stamping area166and the second stamping area167protrude a specific height relative to the skirt edge162on which local stamping processing is not performed, and a protruding direction of the first stamping area166and the second stamping area167is the same as a protruding direction of the bottom edge161relative to the skirt edge162.

Because the first stamping area166and the second stamping area167protrude relative to the skirt edge162on which local stamping processing is not performed, at this position, a height of the skirt edge162of the reinforcement member160is a sum of a height of the stamping area and a height of the skirt edge162on which local stamping processing is not performed, so that a height of the stamping area is greater than the height of the skirt edge162on which local stamping processing is not performed, so as to form the reinforcement member160with a skirt edge of unequal heights.

In an example in which the reinforcement member160shown inFIG.13Bis in a concave state, the first stamping area166and the second stamping area167sink by a specific height relative to the skirt edge162on which local stamping processing is not performed, and a sinking direction is the same as a sinking direction of the bottom edge161relative to the skirt edge162.

FIG.15Ais a perspective view of a structure of a reinforcement member with a skirt edge of unequal heights disposed in a contact area according to an embodiment of this application; andFIG.15Bis an effect diagram of a structure of a reinforcement member with a skirt edge of unequal heights disposed in a contact area according to an embodiment of this application. Referring toFIG.15A, a contact area170(a white dashed line frame) is formed by the flat cable140and the screen outlet line120. When the reinforcement member160is disposed at a position of the middle frame hole132so that the protruding screen chip110is accommodated by the reinforcement member160, both the upper and lower left corners of the reinforcement member160pass through the contact area170. In this case, the reinforcement member160presents a protruding state.

To avoid increasing the height of the part caused by the reinforcement member160passing through the contact area170, the parts that are of the skirt edge162and that are at the upper and lower left corners of the contact area are locally stamped, that is, a height formed by the contact area170is accommodated by using the formed first stamping area166and second stamping area167. Referring toFIG.15B, a height of one end of the contact area170is accommodated by the first stamping area166of the reinforcement member160, and a height of the other end of the contact area170is accommodated by the second stamping area167of the reinforcement member160.

During mounting of the reinforcement member160, a contact between the skirt edge162and the large surface of the screen outlet line120and a contact between the skirt edge162and the flat cable140may be connected through glue dispensing (or spot welding or adhesive). However, because two stamping areas of the reinforcement member160with a skirt edge of unequal heights protrude relative to the remaining part of the skirt edge162, there is a distance between the first stamping area166and the contact area170and between the second stamping area167and the contact area170, and a vertical distance between the first stamping area166and the bottom edge161and a vertical distance between the second stamping area167and the bottom edge161are both less than a vertical distance between the skirt edge162and the bottom edge161, that is, the two stamping areas are in a suspended state, so that the two suspended stamping areas can accommodate a height formed by the contact area170. Therefore, when the two stamping areas pass through the contact area170, glue dispensing is no longer performed.

In some embodiments, the reinforcement member160performs stamping processing on a part of the skirt edge162, and the stamping areas (166and167) are raised integrally in a protruding direction of the bottom edge161, so that the stamping areas form a groove relative to the remaining part of the skirt edge162. Because the height of the contact area170is about 0.1-0.15 mm, the raised heights of the two stamping areas (166and167) are set to 0.1-0.15 mm, so that the depth of the groove formed by the stamping areas (166and167) relative to the remaining part of the skirt edge162is about 0.1-0.15 mm.

When the reinforcement member160with a skirt edge of unequal heights is fastened, because the thickness of the glue dispensing (or spot welding or adhesive) layer is about 0.1 mm, the thickness of the glue dispensing layer is less than or equal to the depth of the groove formed by the stamping areas (166and167) relative to the remaining part of the skirt edge162, glue dispensing may not be performed at a position in which the two stamping areas (166and167) pass through the contact area170, thereby saving glue dispensing space at the position, and avoiding increasing a height of the position. However, glue dispensing is only performed on the remaining part of the skirt edge162, so as to fasten the reinforcement member160. In this case, the two stamping areas (166and167) are suspended relative to the contact area170, and the height of the contact area170is accommodated by the groove formed by the two stamping areas (166and167), so that the overall height of the reinforcement member160does not increase when the reinforcement member160is fastened, and the overall thickness of the electronic device is not increased.

At the positions of the first stamping area166and the second stamping area167, the reinforcement member160is not in contact with the contact area170. Therefore, at the positions, the reinforcement member160does not have a thickness higher than one layer of the flat cable140, and therefore the overall thickness of the electronic device is not increased.

In some embodiments, the start point and the end point of the first stamping area166and the second stamping area167in the reinforcement member160are determined to ensure that the reinforcement member160is not in contact with the contact area170. For example, a distance between the start point (the end point) and the contact area170may be set to about 1 mm.

According to the electronic device provided in this embodiment of this application, the reinforcement member160is disposed at the position of the middle frame hole132, so as to improve reliability of the middle frame131and prevent the screen chip110from continuously sinking. To reduce the overall thickness of the electronic device, in terms of the structural form, the reinforcement member160may be a reinforcement member with a notched skirt edge or a reinforcement member with a skirt edge of unequal heights. Specifically, the first gap164and the second gap165that are formed by the reinforcement member160with a notched skirt edge accommodate the height of the contact area170that is formed by the extension end of the flat cable140and the large surface of the screen outlet line120, or the first stamping area166and the second stamping area167that are formed by the reinforcement member160with a skirt edge of unequal heights accommodate the height of the contact area170that is formed by the extension end of the flat cable140and the large surface of the screen outlet line120. In the foregoing two manners, an increase in a local height may be avoided when the skirt edge162passes through the contact area170, thereby avoiding increasing the overall thickness of the electronic device.

It should be noted that the structural form of the reinforcement member160is not limited to the form provided in the foregoing embodiment; and the reinforcement member160may be in another structural form, provided that a local height is not increased when the reinforcement member160passes through the contact area170, which is not specifically limited herein.

In some embodiments, one screen chip may be disposed in the electronic device provided in the foregoing embodiment. However, to improve efficiency of turning on the display, alternatively, two screen chips may be disposed in the electronic device. For example, the two screen chips may be sequentially arranged in the length direction of the device.

FIG.16is a front perspective view when two screen chips are disposed in an electronic device according to an embodiment of this application. Referring toFIG.16, two screen chips are disposed in the electronic device. The first screen chip110aand the second screen chip110bare sequentially arranged in a length direction of the device, and are sequentially laminated to the large surface of the screen outlet line120. Both the first screen chip110aand the second screen chip110bare located above the battery150. A distance between the two screen chips is set to maximize utilization of the internal space of the device, so as to make full use of the internal space of the device while ensuring data transmission and avoiding increasing the overall thickness of the device.

In this case, the large surface (equivalent to the position of the gasket121) of the screen outlet line120includes two protruding screen chips (110aand110b). Therefore, in addition to avoiding the protruding structure of the screen chip to reduce the overall thickness of the electronic device, the two screen chips (110aand110b) need to be avoided. For information about shapes, sizes, structures, and positions of the two screen chips (110aand110b), refer to description about the case in which one screen chip is disposed in the foregoing embodiment. Details are not described herein again.

In some embodiments, to reduce the overall thickness of the electronic device, in the electronic device provided in this embodiment of this application, internal components of the electronic device are improved, that is, a hole is provided at a position that is at the bottom (a middle frame131) of the battery compartment130and that is opposite to two screen chips (110aand110b), two middle frame holes (132aand132b) are formed on the middle frame131, and the protruding screen chips (110aand110b) are avoided by the middle frame holes (132aand132b), which does not increase a thickness of the remaining part of the middle frame131, thereby reducing the overall thickness.

FIG.17is a rear perspective view when two middle frame holes are provided in a battery compartment according to an embodiment of this application. Referring toFIG.17, a first middle frame hole132aand a second middle frame hole132bare disposed at the bottom (the middle frame131) of the battery compartment130in a length direction of the electronic device. Positions of the first middle frame hole132aand the second middle frame hole132bare opposite to positions of the first screen chip110aand the second screen chip110bthat are laminated to the large surface. That is, the position of the first middle frame hole132ais opposite to the position of the first screen chip110a, and the position of the second middle frame hole132bis opposite to the position of the second screen chip110b. A distance between the two middle frame holes (132aand132b) matches a distance between the two screen chips (110aand110b).

For information about shapes, sizes, and structures of the two middle frame holes (132aand132b), refer to description about the case in which one middle frame hole132is disposed in the battery compartment in the foregoing embodiment. Details are not described herein again.

FIG.18is a rear perspective view when two screen chips are accommodated by two middle frame holes according to an embodiment of this application. Referring toFIG.18, when two screen chips (110aand110b) are accommodated by two middle frame holes (132aand132b), the first screen chip110ais accommodated by the first middle frame hole132a, so that the first screen chip110acan be fully embedded in the first middle frame hole132a; and the second screen chip110bis accommodated by the second middle frame hole132b, so that the second screen chip110bcan be fully embedded in the second middle frame hole132b.

In some embodiments, because the extension end of the flat cable140is laminated to the large surface of the screen outlet line120, the extension end of the flat cable140is also higher than the large surface to form a protruding structure. A thickness of the extension end of the flat cable140needs to be less than the thickness of the screen chip110, so as to avoid a larger avoidance space at the middle frame131, thereby avoiding increasing the overall thickness. In addition to avoiding the first screen chip110aby using the first middle frame hole132aand avoiding the second screen chip110bby using the second middle frame hole132b, the extension end of the flat cable140also needs to be avoided. Therefore, sizes of the two middle frame holes (132aand132b) are larger than a total size of the corresponding screen chips (110aand110b) and the flat cable140. For details about the implementation, reference may be made to related description about the case in which one middle frame hole132is provided in the battery compartment in the foregoing embodiment, and details are not described herein again.

In the electronic device provided in this embodiment of this application, two screen chips (110aand110b) are disposed in the electronic device, and the two screen chips (110aand110b) form protruding structures relative to the large surface of the screen outlet line120. While it is ensured that the middle frame131and the large surface meet a requirement for a minimum safety gap, to avoid contact between the middle frame131and the two screen chips (110aand110b), the middle frame131needs to avoid the two screen chips (110aand110b). In the avoidance manner in this embodiment of this application, two middle frame holes (132aand132b) are disposed at positions of the middle frame131relative to two screen chips (110aand110b), the first middle frame hole132aaccommodates the first screen chip110a, and the second middle frame hole132baccommodates the second screen chip110b, so that the two screen chips (110aand110b) are prevented from moving downward to be in contact with the middle frame131when a user presses the display, thereby avoiding damage. In addition, in the manner of avoiding the screen chips by middle frame holes, the wall thickness of the middle frame131is not increased, and only a minimum wall thickness that meets a reliability requirement needs to be set. It can be learned that, in this avoidance manner, the internal space of the electronic device can be fully used, and the wall thickness of the middle frame131can be reduced while the two screen chips (110aand110b) are avoided, thereby further reducing the overall thickness of the electronic device.

In some embodiments, to avoid two screen chips (110aand110b), two middle frame holes (132aand132b) are disposed in a hollow-out manner at relative positions at the bottom (middle frame131) of the battery compartment130. In this case, the two screen chips (110aand110b) are not separated from the battery150by the middle frame131, and the two middle frame holes (132aand132b) are provided on the middle frame131, which reduces reliability of the middle frame131. Therefore, from a perspective of avoiding significant deformation of the two screen chips (110aand110b) and protecting the battery150, corresponding reinforcement members (160aand160b) may be separately disposed at positions of the two middle frame holes (132aand132b). The two reinforcement members (160aand160b) are used for supporting and positioning, so as to improve reliability of the middle frame131, and avoid significant deformation of the two screen chips (110aand110b) due to applied force. The two reinforcement members (160aand160b) prevent the two screen chips (110aand110b) from continuously sinking, to avoid damage caused by contact between the two screen chips (110aand110b) and the battery150, and prevent the battery150from being damaged by the two screen chips (110aand110b), so as to avoid a risk.

FIG.19is a rear perspective view when two reinforcement members are disposed at positions of two middle frame holes according to an embodiment of this application. Referring toFIG.19, on the basis of the solution for reducing the overall thickness of the electronic device provided in the foregoing embodiment, a first reinforcement member160ais disposed at the position of the first middle frame hole132a, and a second reinforcement member160bis disposed at the position of the second middle frame hole132b. The two reinforcement members (160aand160b) are of the same structure, and both include a bottom edge, a skirt edge, and a middle edge. For information about structures, materials, mounting manners, and lamination manners of the two reinforcement members (160aand160b), refer to related description about the case in which one reinforcement member160is disposed in the middle frame hole132in the foregoing embodiment. Details are not described herein again.

The first dashed-line box inFIG.19is a boundary of the skirt edge of the first reinforcement member160a, and the second dashed-line box is a boundary of the skirt edge of the second reinforcement member160b. In a state shown inFIG.19, the two reinforcement members (160aand160b) are disposed in a protruding state, and corresponding screen chips (110aand110b) are respectively disposed below the two reinforcement members (160aand160b).

Skirt edges of the two reinforcement members (160aand160b) are located between corresponding screen chips and the middle frame131, and corresponding middle frame holes pass through the bottom edge structures of the two reinforcement members (160aand160b). The skirt edge of the first reinforcement member160ais located between the first screen chip110aand the middle frame131, and is configured to prevent the first screen chip110afrom being in contact with the battery150when the first screen chip110asinks due to applied force. The first middle frame hole132apasses through the bottom edge structure of the first reinforcement member160a, so as to implement an effect of accommodating the first screen chip110aby the protruding part of the first reinforcement member160a. The skirt edge of the second reinforcement member160bis located between the second screen chip110band the middle frame131, and is configured to prevent the second screen chip110bfrom being in contact with the battery150when the second screen chip110bsinks due to applied force. The second middle frame hole132bpasses through the bottom edge structure of the second reinforcement member160b, to implement an effect of accommodating the second screen chip110bby the protruding part of the second reinforcement member160b.

A complete structure obtained after the two reinforcement members (160aand160b) are taken out from the electronic device is shown inFIG.7. A structural form of the two reinforcement members (160aand160b) may be a reinforcement member with a notched skirt edge shown inFIG.11AandFIG.11B, or a reinforcement member with a skirt edge of unequal heights shown inFIG.13AandFIG.13B. For an implementation solution for avoiding the contact area170by a structural form of two reinforcement members (160aand160b), refer to description about avoiding the contact area170by the reinforcement member160in the foregoing embodiment. Details are not described herein again.

The two screen chips (110aand110b) are separated from the battery150by using bottom edges of the two reinforcement members (160aand160b). If the user presses the display to cause significant deformation of the two screen chips (110aand110b), the bottom edges of the two reinforcement members (160aand160b) may prevent corresponding screen chips (110aand110b) from continuously sinking, so as to avoid contact with the battery150. Even if the two screen chips (110aand110b) are damaged because of contact with the bottom edges of the corresponding reinforcement members, the two reinforcement members (160aand160b) may hold fragments, to prevent the fragments from being in contact with the battery150, so as to protect the battery150.

According to the electronic device provided in this embodiment of this application, to reduce the overall thickness of the electronic device, two middle frame holes (132aand132b) are disposed at the positions of the middle frame131relative to the two screen chips (110aand110b), the two middle frame holes (132aand132b) accommodate corresponding screen chips (110aand110b), and the middle frame131has a minimum wall thickness. In addition, corresponding reinforcement members (160aand160b) are disposed at the positions of the two middle frame holes (132aand132b), and the reinforcement members (160aand160b) are used for supporting and positioning, so as to improve reliability of the middle frame131, prevent the corresponding screen chips (110aand110b) from continuously sinking, thereby avoiding damage caused by contact between the two screen chips (110aand110b) and the battery150and protecting the battery150. It can be learned that the two middle frame holes (132aand132b) and the two reinforcement members (160aand160b) are disposed on the middle frame131, so as to improve reliability of the middle frame131and avoid the two protruding screen chips (110aand110b), thereby reducing an overall thickness of an electronic device.

In some embodiments, when two screen chips (110aand110b) are disposed in the electronic device, one middle frame hole132may alternatively be provided on the middle frame131, and the middle frame hole132can accommodate the two screen chips. In this case, structural features such as a size and a shape of the only middle frame hole need to match the structural features such as a size and a shape of an area enclosed by the two screen chips, that is, a size of the middle frame hole132is greater than a size that is enclosed by the first screen chip110aand the second screen chip110b. For the solution for accommodating two screen chips by one middle frame hole, refer to description in the foregoing embodiments. Details are not described herein again.

It can be learned from the foregoing technical solutions that, in the electronic device provided in the embodiments of this application, to resolve a problem that the overall thickness of the electronic device increases due to a local protrusion inside a device, while it is ensured that the middle frame131and the large surface of the screen outlet line120meet a requirement for a minimum safety gap, a position corresponding to the screen chip110on the middle frame131is hollowed out to form the middle frame hole132, so as to avoid contact between the middle frame131and the screen chip110, so that the screen chip110is accommodated in the space of the wall thickness of the middle frame131. In this manner of avoiding the screen chip110, only a minimum wall thickness that meets a reliability requirement needs to be set. In addition, the reinforcement member160is disposed at a position of the middle frame hole132, and the reinforcement member160is used for supporting and positioning, so as to improve reliability of the middle frame131and prevent the screen chip110from continuously sinking. Furthermore, the clamping slot133on the middle frame131accommodates the skirt edge162of the reinforcement member160, to avoid that the top of the skirt edge162is exposed beyond the top of the middle frame131, so as to ensure that a minimum safety gap is reserved between the middle frame131and the large surface of the screen outlet line120, thereby reducing the overall thickness of the electronic device. A structural form of the reinforcement member160may be a reinforcement member with a notched skirt edge or a reinforcement member with a skirt edge of unequal heights, to avoid a height of the contact area170formed by the flat cable140and the screen outlet line120, so as to avoid increasing the overall thickness of the electronic device. It can be learned that the internal space of the electronic device can be fully used, so that the wall thickness of the middle frame131is reduced, and the height formed by contact between adjacent components is avoided while the screen chip110is avoided, thereby further reducing the overall thickness of the electronic device.
