Patent Description:
This application relates to the field of electronic device technologies, and in particular, to an electronic device.

In recent years, with development of flexible screen technologies, structures such as folding structures of some electronic devices with display screens are implemented, for example, folding screen mobile phones and folding screen wearable devices. In an electronic device, an antenna structure usually needs to be provided for communication.

The antenna structure, for example, an antenna, provided in the electronic device usually needs to be fed and grounded. The grounding requires connection to a common ground terminal of the electronic device, and the common ground terminal is generally a middle frame, a housing, or the like of the electronic device.

A morphological structure of a non-folding electronic device does not change. A position for disposing an antenna is determined during production, and a length of a grounding path does not change. However, a morphological structure of a folding electronic device changes with a folding status. Further, a length of a grounding path of the antenna may not be the shortest. Consequently, performance of the antenna and interference are affected.

<CIT> relates to the technical field of mobile terminals, and particularly discloses a foldable mobile terminal. The foldable mobile terminal comprises: an upper antenna and a lower antenna; and a first contact point and a second contact point. The first contact point is connected to the upper antenna, and the second contact point is connected to the lower antenna and is used for touching the first contact point. When the foldable mobile terminal is folded so that the first contact point and the second contact touch each other, the upper antenna and the lower antenna may form a new antenna.

Embodiments of this application provide an electronic device to reconstruct a grounding path of an antenna when the electronic device is in a folded state, so as to prevent deterioration of performance of the antenna. Embodiments not falling within the scope of the claims are for illustration only.

An embodiment of this application provides an electronic device. The electronic device includes: a rotating shaft;.

According to the electronic device provided in this embodiment of this application, because the first enclosure is provided with the first elastic component, the first elastic component may electrically connect the first enclosure to the second enclosure when the first enclosure and the second enclosure are in the folded state. In this way, a grounding path is reconstructed in the folded state, the first elastic component may be disposed based on a position of an antenna and a nearest grounding path that can be implemented by the antenna, thereby adapting to a nearest grounding design of the electronic device in the folded state to prevent deterioration of performance of the antenna.

The first enclosure is provided with the first elastic component. Therefore, when the first enclosure and the second enclosure are in the folded state, the first elastic component may directly abut against the second enclosure, or a mechanical part that may cooperate with the first elastic component may be disposed at a position, corresponding to the first elastic component, on the second enclosure, so that the first elastic component engages with and abuts against the mechanical part. According to a specific configuration, for example, the mechanical part may be a second elastic component whose structure is the same as that of the first elastic component, or does not have a structure such as an elastic bulge or recess.

Optionally, the electronic device further includes a second elastic component, the second elastic component is disposed in the second enclosure, the second elastic component is disposed in correspondence with the first elastic component, the first elastic component abuts against the second elastic component when the first enclosure and the second enclosure are in the folded state, and the first electric-conductor and the second electric-conductor are electrically connected to the second elastic component through the first elastic component. The second enclosure is provided with the second elastic component. When the first enclosure and the second enclosure are in the folded state, the two elastic contact components engage with and abut against each other. An operation is labor-saving on the premise of ensuring an elastic electrical connection. In addition, a specific structure of the second elastic component may be consistent with a specific structure of the first elastic component.

Optionally, the second enclosure is provided with a protrusion in correspondence with the first elastic component, the protrusion is disposed in correspondence with the first elastic component, and the first elastic component abuts against the protrusion when the first enclosure and the second enclosure are in the folded state. The protrusion can be disposed easily, facilitating production and layout. In addition, the cooperation between the protrusion and the first elastic component may be implemented through cooperation between end portions of the two parts or through cooperation between side walls of the two parts. Alternatively, the second enclosure is provided with a dent in correspondence with the first elastic component, the dent is disposed in correspondence with the first elastic component, and the first elastic component extends into the dent and abuts against the dent when the first enclosure and the second enclosure are in the folded state. The dent can be provided conveniently and positions of two sides of the first elastic component are limited after the first elastic component extends into the dent. Therefore, the connection is stable.

The electronic device has two states, namely, the unfolded state and the folded state. When the first enclosure and the second enclosure are in the unfolded state, a part of the first elastic component may be located outside the first enclosure, or the first elastic component may be completely located inside the first enclosure, provided that the first enclosure is elastically and electrically connected to the second enclosure when the first enclosure and the second enclosure are in the folded state. The solution in which a part of the first elastic component is located outside the first enclosure when the first enclosure and the second enclosure are in the unfolded state can be easily implemented. Furthermore, during connection, there is an elastic force serving as a holding force to make the connection tighter. The solution in which the first elastic component is completely located inside the first enclosure when the first enclosure and the second enclosure are in the unfolded state can improve an appearance effect.

When the first enclosure and the second enclosure are in the unfolded state, a part of the first elastic component may be located outside the first enclosure. For example, one end of the first elastic component extends out of the first enclosure. When the first enclosure and the second enclosure are in the folded state, the first elastic component is squeezed by the second enclosure and is elastically and electrically connected to the second enclosure to elastically and electrically connect the first enclosure to the second enclosure. When the first enclosure and the second enclosure are in the folded state, the first elastic component is squeezed by the second enclosure, so that the first elastic component has an elastic force against the second enclosure. This is equivalent to providing a retention force for the first elastic component to abut against the second enclosure. In this way, it can be ensured that the first elastic component is in closer contact with the second enclosure and the electrical connection is more reliable. Optionally, the first enclosure is provided with a mounting groove, a first end of the first elastic component is disposed in the mounting groove, the first end of the first elastic component is connected to the first enclosure, and a second end of the first elastic component extends out of the mounting groove.

Optionally, the first elastic component includes an elastic mechanical part and a contact member, a first end of the elastic mechanical part is the first end of the first elastic component and is located in the mounting groove, the first end of the elastic mechanical part is connected to the first enclosure, a second end of the elastic mechanical part is connected to a first end of the contact member, and a second end of the contact member is the second end of the first elastic component and extends out of the mounting groove. The first elastic component may be implemented in a plurality of manners, provided that the first elastic component can be elastically deformed and can connect the first enclosure to the second enclosure. For ease of implementation, the first elastic component may include the elastic mechanical part and the contact member. The elastic mechanical part is configured to be elastically deformed under a force and generate an elastic force in a direction opposite to a force bearing direction. The contact member is configured to connect to and come into contact with the second enclosure.

In the solution in which a part of the first elastic component is located outside the first enclosure when the first enclosure and the second enclosure are in the unfolded state, the first elastic component is squeezed by the second enclosure when the first enclosure and the second enclosure are in the folded state. To ensure normal elastic contact, the first elastic component may be implemented in a plurality of manners. For example, the first end of the elastic mechanical part is fixedly connected to the first enclosure, and the second end of the elastic mechanical part is fixedly connected to the first end of the contact member. A fixed connection manner includes, but is not limited to, a buckle connection, welding, riveting, or the like.

Alternatively, the first end of the elastic mechanical part abuts against and is connected to the first enclosure, and the second end of the elastic mechanical part abuts against and is connected to the first end of the contact member.

In the solution in which the two ends of the elastic mechanical part abut against other objects, because the two ends of the elastic mechanical part are not fastened, a specific position and an expansion direction of the elastic mechanical part need to be considered. In addition, under the elastic force of the elastic mechanical part, if the position of the contact member is not limited, the contact member may be ejected out of the mounting groove by the elastic mechanical part and is separated from the elastic mechanical part. Therefore, specifically, a side of the mounting groove facing toward the second enclosure is provided with an opening. A shape of the opening matches the contact member, the first end of the contact member is located in the mounting groove, the first end of the contact member includes a position limiter, an outer contour of the position limiter is greater than the opening of the mounting groove, and the second end of the contact member extends out of the opening of the mounting groove. The position limiter of the contact member cooperates with the opening of the mounting groove, so that motion of the contact member is limited. Even if the elastic mechanical part exerts an elastic force to the contact member, the second end of the contact member extends out of the opening of the mounting groove. However, the outer contour of the position limiter is greater than the opening of the mounting groove, the position limiter cannot pass through the opening of the mounting groove, therefore, prevents the contact member from keeping moving, and further can prevent the contact member from being ejected out by the elastic mechanical part and becoming separated.

The elastic mechanical part needs to be elastically deformed, and may be implemented in a plurality of manners, for example, an elastic block made of an elastic material or a spring. The spring is a manner that may be easily implemented. Specifically, the elastic mechanical part is a spring. In addition, a structure matching the spring needs to be disposed. For example, the electronic device further includes a first sleeve and a second sleeve, the first sleeve is slidably sleeved on the second sleeve, the first sleeve and the second sleeve are disposed in the mounting groove, and the spring is disposed in the first sleeve and the second sleeve. The first sleeve and the second sleeve on which the first sleeve is slidably sleeved not only can protect the spring, but also can guide and cooperate with an elastic motion of the spring.

A specific implementation in which the first sleeve is slidably sleeved on the second sleeve may be that the first sleeve is fastened to the mounting groove, an extension direction of the first sleeve is consistent with that of the second sleeve, and the first sleeve and the second sleeve are slidably sleeved together. An end of the first sleeve and an end of the second sleeve each have an opening, and the opening of the first sleeve is opposite to the opening of the second sleeve. An extension direction of the spring is consistent with that of the first sleeve. Further, the spring may be located in the first sleeve.

Because when the first enclosure and the second enclosure are in the folded state, the first elastic component is elastically deformed and is further connected to the second enclosure only after being squeezed by the second enclosure. However, because a force required by the first elastic component to undergo a deformation is approximately vertical to a force exerted to the first elastic component in a folding process of the electronic device, it is possible that the first elastic component can only prevent the electronic device from being folded and cannot be elastically deformed normally. Therefore, an edge of the first elastic component first coming into contact with the second enclosure needs to be provided with a slope that can provide guidance, so that there is an acute angle between the force exerted to the first elastic component when the electronic device is folded and the force required by the first elastic component for deformation. Further, the first elastic component can be elastically deformed successfully, and is snap-fitted and is elastically in contact with and connected to the first enclosure. Therefore, optionally, an end surface of the second end of the first elastic component is a slope. In the folding process of the electronic device, when the contact member is in contact with the second enclosure, the slope is configured to guide the first elastic component to be elastically deformed toward an inner portion of the first enclosure.

When the first enclosure and the second enclosure are in the unfolded state, the first elastic component may be completely located in the inner portion of the first enclosure. For example, the first elastic component is located in the inner portion of the first enclosure, the second enclosure is provided with a magnetic part in correspondence with the first elastic component, and the magnetic part is disposed in correspondence with the first elastic component. The first enclosure is provided with a mounting groove, the first end of the first elastic component is disposed in the mounting groove and is connected to the first enclosure, and the second end of the first elastic component is located in the mounting groove when the first enclosure and the second enclosure are in the unfolded state. When the first enclosure and the second enclosure are in the folded state, the second end of the first elastic component is attracted by the magnetic part, the first elastic component extends out of the mounting groove, and the first electric-conductor and the second electric-conductor are electrically connected to the magnetic part through the first elastic component. That is, when the first enclosure and the second enclosure are in the folded state, the magnetic part and the first elastic component are attracted by each other, so that an end of the first elastic component extends out of the mounting groove and is electrically connected to the second enclosure. In this way, when the first enclosure and the second enclosure are in the unfolded state, the first elastic component is located in the mounting groove and can be well hidden to improve an appearance effect of the electronic device. In addition, this can be easily implemented in an attraction manner by using the magnetic part, no extra force needs to be applied, and the part cannot be damaged easily.

Optionally, the first elastic component includes an elastic mechanical part and a contact member, a first end of the elastic mechanical part is the first end of the first elastic component and is disposed in the mounting groove, the first end of the elastic mechanical part is connected to the first enclosure, a second end of the elastic mechanical part is connected to a first end of the contact member, and a second end of the contact member is the second end of the first elastic component and is located in the mounting groove. The first elastic component may be implemented in a plurality of manners, provided that the first elastic component can be elastically deformed and can connect the first enclosure to the second enclosure. For ease of implementation, the first elastic component may include an elastic mechanical part and a contact member, and the elastic mechanical part is disposed in the mounting groove. The elastic mechanical part is configured to be elastically deformed under a force and generate an elastic force in a direction opposite to a force bearing direction. The contact member is configured to connect to and come into contact with the second enclosure.

In the solution in which the first elastic component may be completely located inside the first enclosure when the first enclosure and the second enclosure are in the unfolded state, the first elastic component is attracted by the magnetic part when the first enclosure and the second enclosure are in the folded state. To ensure normal elastic contact, the first elastic component may be implemented in a plurality of manners. For example, the first end of the elastic mechanical part is fixedly connected to the first enclosure, and the second end of the elastic mechanical part is fixedly connected to the first end of the contact member. A fixed connection manner includes, but is not limited to, a buckle connection, welding, riveting, or the like.

The elastic mechanical part needs to be elastically deformed, and may be implemented in a plurality of manners, for example, an elastic block made of an elastic material or a spring. The spring is a manner that can be easily implemented. Specifically, optionally, the elastic mechanical part is a spring, the first elastic component further includes a spring sleeve configured to accommodate the spring, the contact member is provided with an accommodation groove, the elastic mechanical part is located in the accommodation groove, the spring sleeve is fixedly connected to the first enclosure, an end of the spring sleeve facing toward an inner portion of the first enclosure has an opening, and an end of the spring extends out of the opening of the spring sleeve and is connected to an inner wall of the accommodation groove.

The first elastic component may be disposed based on an actual requirement. Generally, an available space inside the electronic device is small and a plurality of other functional members need to be mounted to implement other required functions, for example, a processor, a camera, and a voice output. Therefore, a space reserved for the antenna is limited, and the first elastic component may be disposed at a position close to the antenna. Optionally, the first enclosure is articulated with the second enclosure through an articulated shaft. The first elastic component is disposed on a side of the first enclosure far away from the articulated shaft. When the first enclosure and the second enclosure are in the folded state, the first elastic component is elastically deformed, and the first elastic component may be communicated with a side of the second enclosure far away from the articulated shaft, to elastically and electrically connect the first enclosure to the second enclosure.

Optionally, an elastomer is fastened to the first elastic component, and an elastic free end of the elastomer is slidably and elastically in contact with and connected to the first enclosure. When the first enclosure and the second enclosure are in the folded state, the first enclosure may be communicated with the second enclosure by using a connection relationship between the elastic mechanical part, the contact member, and the first enclosure. Alternatively, another implementation may be used. To ensure a stable electrical connection between the first enclosure and the second enclosure, the elastomer is disposed. An end of the elastomer is fastened to the first elastic component, and another end is the elastic free end and is slidably and elastically in contact with and connected to the first enclosure. In this way, when the first elastic component is deformed, the elastomer moves with the deformation. In this process, the elastomer is always slidably and elastically in contact with and connected to the first enclosure. Therefore, the stable electrical connection between the first enclosure and the second enclosure can be ensured.

Optionally, to implement a plurality of grounding paths, there are a plurality of first elastic components, and the plurality of first elastic components are sequentially disposed along a side edge of the first enclosure. In this way, an elastic electrical connection between each first elastic component and the second enclosure may be a nearest grounding path of an antenna, and a plurality of antennas can be grounded through a shortest path in different positional conditions.

When the first enclosure and the second enclosure are folded together, if a shape of the first enclosure matches that of the second enclosure, and the first enclosure and the second enclosure are overlapped, the first elastic component disposed on the first enclosure can be connected to the second enclosure only after thicknesses of the first enclosure and the second enclosure are eliminated. Further, the first elastic component may need to be configured as a structure with a bending portion, or a bending structure may need to be disposed on the second enclosure. However, such a solution does not facilitate production and assembly and is not beautiful enough. Therefore, optionally, a side edge of the second enclosure is provided with a thickness cooperation portion, a thickness of the thickness cooperation portion is greater than or equal to a sum of the thicknesses of the first enclosure and the second enclosure, and the first elastic component elastically and electrically connects the side edge of the first enclosure to the thickness cooperation portion of the second enclosure when the first enclosure and the second enclosure are in the folded state. After the thickness cooperation portion is disposed on the second enclosure, the first elastic component may be elastically and electrically connected to the thickness cooperation portion when the first enclosure and the second enclosure are in the folded state. Further, no structure with a bending portion needs to be disposed inside the first elastic component, nor a bending structure needs to be disposed on the second enclosure. In addition, a shape of the thickness cooperation portion may be configured based on the shape of the second enclosure to ensure the appearance effect.

The following clearly describes the technical solutions in embodiments of the present invention with reference to the accompanying drawings in embodiments of the present invention. It is clear that the described embodiments are merely some rather than all of embodiments of the present invention. Embodiments of the present invention may be applied to an electronic device, including but not limited to a foldable mobile phone, a watch, a computer, or the like. A foldable structure may be a foldable display screen or a foldable housing.

An antenna is a part configured to transmit and receive electromagnetic waves. The antenna usually needs to be fed and grounded. The grounding needs to be as short as possible and a grounding end needs to be connected in a shortest path to avoid affecting performance of the antenna. An existing electronic device has two states, namely, an unfolded state and a folded state. Specifically, as shown in <FIG> is a schematic diagram of a structure of an electronic device in the unfolded state, and <FIG> is a schematic diagram of a structure of the electronic device in the folded state. The electronic device includes a left middle frame <NUM> and a right middle frame <NUM> that are articulated with each other through a rotating shaft <NUM>. The left middle frame <NUM> may be provided with a first antenna <NUM>, and the right middle frame <NUM> may be provided with a second antenna <NUM>. Both the left middle frame <NUM> and the right middle frame <NUM> serve as grounding ends. Both the first antenna <NUM> and the second antenna <NUM> need to be connected to the grounding ends of the left middle frame <NUM> and the right middle frame <NUM>. The left middle frame <NUM> and the right middle frame <NUM> are grounded through the rotating shaft <NUM>. Refer to <FIG>. When a first enclosure and a second enclosure are in the unfolded state, the first antenna <NUM> needs to be connected to both the left middle frame <NUM> and the right middle frame <NUM> to be grounded. Because the first antenna <NUM> is disposed on the left middle frame <NUM>, a connection path between the first antenna <NUM> and the right middle frame <NUM> is a grounding path, that is, the grounding path of the first antenna <NUM> is a path a shown in <FIG>. Because the second antenna <NUM> is disposed on the right middle frame <NUM>, a connection path between the second antenna <NUM> and the left middle frame <NUM> is a grounding path, that is, the grounding path of the second antenna <NUM> is a path b shown in <FIG>. In this case, because the left middle frame <NUM> and the right middle frame <NUM> are in the unfolded state, both the grounding path a and the grounding path b are shortest grounding paths. Next, refer to <FIG>. When the first enclosure and the second enclosure are in the folded state, the grounding path of the first antenna <NUM> is still the path a and the grounding path of the second antenna <NUM> is still the path b. However, because the left middle frame <NUM> and the right middle frame <NUM> are overlapped, in spatial orientation, the first antenna <NUM> may be connected to the right middle frame <NUM> through a path c. In comparison, the path a is longer than the path c. Similarly, in spatial orientation, the second antenna <NUM> may be connected to the left middle frame <NUM> through a path d. In comparison, the path b is longer than the path d. Therefore, in the folded state, a shape of the existing electronic device is changed, and the original grounding path of the antenna is no longer the shortest grounding path. However, a long grounding path causes a current signal loss and interference. This deteriorates the performance of the antenna.

In addition, refer to <FIG>. When the existing electronic device is in the folded state, the left middle frame <NUM> and the right middle frame <NUM> may be directly overlapped together, and are communicated with each other through two planes that are in contact with each other. However, such a contact manner cannot ensure a close connection, the electrical connection and contact may be poor, electrical conductivity is very unstable, and the performance of the antenna cannot be ensured. Furthermore, if the left middle frame <NUM> and the right middle frame <NUM> are prevented from coming into contact through insulation, the foregoing problem in which the performance of the antenna is affected because the grounding path of the antenna is not the shortest grounding path when the electronic device is in the folded state occurs.

Refer to <FIG> and <FIG>. An embodiment of this application provides an electronic device, including:.

According to the electronic device provided in this embodiment of this application, because the first elastic component <NUM> is disposed between the first enclosure <NUM> and the second enclosure <NUM>, the first elastic component <NUM> may elastically and electrically connect the first electric-conductor to the second electric-conductor when the first enclosure <NUM> and the second enclosure <NUM> are in the folded state. In this way, a grounding path is constructed by using the first elastic component when the electronic device is in the folded state, the first elastic component <NUM> may be disposed based on a position of an antenna and a shortest grounding path that can be implemented by the antenna, thereby adapting to a shortest grounding design of the electronic device in the folded state to prevent deterioration of performance of the antenna. In addition, the elastic electrical connection is close and poor contact does not occur.

It should be noted that the electronic device provided in this embodiment of this application has two states, namely, the unfolded state and the folded state. Specifically, refer to <FIG>. The first enclosure <NUM> is rotatably connected to the second enclosure <NUM> through an articulated shaft <NUM>, and the electronic device is in the unfolded state. In this case, the articulated shaft <NUM> is located between the first enclosure <NUM> and the second enclosure <NUM>, and the first enclosure <NUM> and the second enclosure <NUM> are located on a same horizontal plane. Refer to <FIG>. The electronic device is in the unfolded state. In this case, the articulated shaft <NUM> is located on one side of the first enclosure <NUM> and the second enclosure <NUM>, and the first enclosure <NUM> and the second enclosure <NUM> are overlapped. In addition, in the electronic device in this embodiment of this application, that the enclosure <NUM> includes the first electric-conductor and the second enclosure <NUM> includes the second electric-conductor means that the electronic device generally has a grounding end. The grounding end may be an electrically conductive enclosure (for example, an enclosure made of a conductive metal), or may be another part disposed in the enclosure. Therefore, the enclosure may be made of a non-conductive material such as plastic, and cannot be directly used as a grounding end. Therefore, it is defined herein that the first enclosure <NUM> includes the first electric-conductor and the second enclosure <NUM> includes the second electric-conductor. The first enclosure <NUM> may be the first electric-conductor on the whole, or may include a non-conductive housing and the first electric-conductor disposed in the housing. Similarly, the second enclosure <NUM> may be the second electric-conductor on the whole, or may include a non-conductive housing and the second electric-conductor disposed in the housing.

The first enclosure <NUM> is provided with the first elastic component <NUM>. Therefore, when the first enclosure <NUM> and the second enclosure <NUM> are in the folded state, the first elastic component <NUM> may directly abut against the second enclosure <NUM>, or a mechanical part that may cooperate with the first elastic component <NUM> may be disposed at a position, corresponding to the first elastic component <NUM>, on the second enclosure <NUM>, so that the first elastic component <NUM> engages with and abuts against the mechanical part. According to a specific configuration, for example, the mechanical part may be a second elastic component whose structure is the same as that of the first elastic component <NUM>, or does not have a structure such as an elastic bulge or recess.

The mechanical part engaging with and abutting against the first elastic component <NUM> may be implemented in a plurality of manners. For example, the electronic device further includes a second elastic component, the second elastic component is disposed in the second enclosure <NUM>, the second elastic component is disposed in correspondence with the first elastic component <NUM>, the first elastic component <NUM> abuts against the second elastic component when the first enclosure <NUM> and the second enclosure <NUM> are in the folded state, and the first electric-conductor and the second electric-conductor are electrically connected to the second elastic component through the first elastic component <NUM>. The second enclosure <NUM> is provided with the second elastic component. When the first enclosure and the second enclosure are in the folded state, the two elastic contact components engage with and abut against each other. An operation is labor-saving on the premise of ensuring an elastic electrical connection. In addition, a specific structure of the second elastic component may be consistent with a specific structure of the first elastic component <NUM>.

Alternatively, the second enclosure <NUM> is provided with a protrusion <NUM> in correspondence with the first elastic component <NUM>, the protrusion <NUM> is disposed in correspondence with the first elastic component <NUM>, and the first elastic component <NUM> abuts against the protrusion <NUM> when the first enclosure <NUM> and the second enclosure <NUM> are in the folded state. The protrusion <NUM> can be disposed easily, facilitating production and layout. In addition, the cooperation between the protrusion <NUM> and the first elastic component <NUM> may be implemented through cooperation between end portions of the two parts or through cooperation between side walls of the two parts. Alternatively, the second enclosure <NUM> is provided with a dent in correspondence with the first elastic component <NUM>, the dent is disposed in correspondence with the first elastic component <NUM>, and the first elastic component <NUM> extends into the dent and abuts against the dent when the first enclosure <NUM> and the second enclosure <NUM> are in the folded state. The dent can be provided conveniently and positions of two sides of the first elastic component <NUM> are limited after the first elastic component <NUM> extends into the dent. Therefore, the connection is stable.

When the first enclosure <NUM> and the second enclosure <NUM> are in the unfolded state, a part of the first elastic component <NUM> may be located outside the first enclosure <NUM>, or the first elastic component <NUM> may be completely located inside the first enclosure <NUM>, provided that the first enclosure <NUM> is elastically and electrically connected to the second enclosure <NUM> when the first enclosure <NUM> and the second enclosure <NUM> are in the folded state. The solution in which a part of the first elastic component <NUM> is located outside the first enclosure <NUM> when the first enclosure <NUM> and the second enclosure <NUM> are in the unfolded state can be easily implemented. Furthermore, during connection, there is an elastic force serving as a holding force to make the connection tighter. The solution in which the first elastic component <NUM> is completely located inside the first enclosure <NUM> when the first enclosure and the second enclosure are in the unfolded state can improve an appearance effect.

In the electronic device in this embodiment, when the electronic device is in the unfolded state, a part of the first elastic component <NUM> may be located outside the first enclosure <NUM>. As shown in <FIG>, <FIG>, and <FIG>, when the first enclosure and the second enclosure are in the folded state, the first elastic component <NUM> is squeezed by the second enclosure <NUM> and is elastically and electrically connected to the second enclosure <NUM>. The first enclosure <NUM> is elastically and electrically connected to the second enclosure <NUM> through the first elastic component <NUM>. When the first enclosure <NUM> and the second enclosure <NUM> are in the folded state, the first elastic component <NUM> is squeezed by the second enclosure <NUM>, so that the first elastic component <NUM> has an elastic force against the second enclosure <NUM>. In this way, it can be ensured that the first elastic component <NUM> is in closer contact with the second enclosure <NUM> and the electrical connection is more reliable.

Optionally, as shown in <FIG> and <FIG>, the first enclosure <NUM> is provided with a mounting groove <NUM>, a first end of the first elastic component <NUM> is disposed in the mounting groove <NUM>, the first end of the first elastic component <NUM> is connected to the first enclosure <NUM>, and a second end of the first elastic component <NUM> extends out of the mounting groove <NUM>.

The first elastic component <NUM> may be implemented in a plurality of manners, provided that the first elastic component <NUM> can be elastically deformed and can connect the first enclosure <NUM> to the second enclosure <NUM>. For ease of implementation, the first elastic component <NUM> may include an elastic mechanical part <NUM> and a contact member <NUM>. The elastic mechanical part <NUM> is configured to be elastically deformed under a force and generate an elastic force in a direction opposite to a force bearing direction. The contact member <NUM> is configured to connect to and come into contact with the second enclosure <NUM>. Specifically, as shown in <FIG> and <FIG>, the first elastic component <NUM> includes an elastic mechanical part <NUM> and a contact member <NUM>, a first end of the elastic mechanical part <NUM> is the first end of the first elastic component <NUM> and is located in the mounting groove <NUM>, the first end of the elastic mechanical part <NUM> is connected to the first enclosure <NUM>, a second end of the elastic mechanical part <NUM> is connected to a first end of the contact member <NUM>, and a second end of the contact member <NUM> is the second end of the first elastic component <NUM> and extends out of the mounting groove <NUM>.

In the solution in which a part of the first elastic component <NUM> is located outside the first enclosure <NUM> when the first enclosure and the second enclosure are in the unfolded state, the first elastic component <NUM> is squeezed by the second enclosure <NUM> when the first enclosure <NUM> and the second enclosure <NUM> are in the folded state. To ensure normal elastic contact, the first elastic component <NUM> may be implemented in a plurality of manners. For example, as shown in <FIG>, the first end of the elastic mechanical part <NUM> is fixedly connected to and abuts against the first enclosure <NUM>, and the second end of the elastic mechanical part <NUM> is fixedly connected to and abuts against the first end of the contact member <NUM>. A fixed connection manner includes, but is not limited to, a buckle connection, welding, riveting, or the like.

Alternatively, the first end of the elastic mechanical part <NUM> abuts against and is connected to the first enclosure <NUM>, and the second end of the elastic mechanical part <NUM> abuts against and is connected to the first end of the contact member <NUM>.

In the solution in which the two ends of the elastic mechanical part <NUM> abut against other objects, because the two ends of the elastic mechanical part <NUM> are not fastened, a specific position and an expansion direction of the elastic mechanical part <NUM> need to be considered. In addition, under the elastic force of the elastic mechanical part <NUM>, if the position of the contact member <NUM> is not limited, the contact member <NUM> may be ejected out of the mounting groove <NUM> by the elastic mechanical part <NUM> and is separated from the elastic mechanical part <NUM>. Therefore, specifically, as shown in <FIG>, <FIG>, a side of the mounting groove <NUM> facing toward the second enclosure <NUM> is provided with an opening <NUM>. As shown in <FIG> and <FIG>, a shape of the opening <NUM> matches the contact member <NUM>, the first end of the contact member <NUM> extends out of the opening <NUM> of the mounting groove <NUM>, the second end of the contact member <NUM> is located in the mounting groove <NUM>, the first end of the contact member <NUM> includes a position limiter <NUM>, an outer contour of the position limiter <NUM> is greater than the opening <NUM> of the mounting groove, and the second end of the contact member <NUM> extends out of the opening <NUM> of the mounting groove. The position limiter <NUM> of the contact member <NUM> cooperates with the opening <NUM> of the mounting groove <NUM>, so that motion of the contact member <NUM> is limited. Even if the elastic mechanical part <NUM> exerts an elastic force to the contact member <NUM>, the second end of the contact member <NUM> extends out of the opening <NUM> of the mounting groove <NUM>. However, the outer contour of the position limiter <NUM> is greater than the opening <NUM> of the mounting groove <NUM>, the position limiter <NUM> cannot pass through the opening <NUM> of the mounting groove <NUM>, therefore, prevents the contact member <NUM> from keeping moving, and further can prevent the contact member <NUM> from being ejected out by the elastic mechanical part <NUM> and becoming separated.

It should be noted that, as shown in <FIG>, <FIG>, a specific structure thereof may be configured based on space and requirements, provided that the outer contour of the position limiter <NUM> is greater than the opening <NUM> of the mounting groove <NUM> and does not match the opening <NUM>, and the position limiter <NUM> cannot pass through the opening <NUM>. For example, as shown in <FIG> and <FIG>, the position limiter <NUM> is a structure formed by turning an edge of the first end of the contact member <NUM> toward a radial direction of the contact member <NUM>.

The elastic mechanical part <NUM> needs to be elastically deformed, and may be implemented in a plurality of manners, for example, an elastic block made of an elastic material or a spring. The spring is a manner that may be easily implemented. Specifically, the elastic mechanical part <NUM> is a spring. In addition, a structure matching the spring needs to be disposed. For example, as shown in <FIG>, the electronic device further includes a first sleeve <NUM> and a second sleeve <NUM>, the first sleeve <NUM> is slidably sleeved on the second sleeve <NUM>, the first sleeve <NUM> and the second sleeve <NUM> are disposed in the mounting groove <NUM>, and the spring is disposed in the first sleeve <NUM> and the second sleeve <NUM>. The first sleeve <NUM> and the second sleeve <NUM> on which the first sleeve <NUM> is slidably sleeved not only can protect the spring, but also can guide and cooperate with an elastic motion of the spring.

A specific implementation in which the first sleeve is slidably sleeved on the second sleeve may be that, as shown in <FIG>, the elastic mechanical part <NUM> is a spring, and the first elastic component <NUM> further includes the first sleeve <NUM> and the second sleeve <NUM> that are configured to accommodate the spring <NUM>. As shown in <FIG>, the first sleeve <NUM> is fastened to the mounting groove <NUM>, an extension direction of the first sleeve <NUM> is consistent with that of the second sleeve <NUM>, and the first sleeve <NUM> and the second sleeve <NUM> are slidably sleeved together. An end of the first sleeve <NUM> and an end of the second sleeve <NUM> each have an opening, and the opening of the first sleeve <NUM> is opposite to the opening of the second sleeve <NUM>. An extension direction of the spring is consistent with that of the first sleeve <NUM>. Further, the spring may be located in the first sleeve <NUM>.

Because when the first enclosure and the second enclosure are in the folded state, the first elastic component <NUM> is elastically deformed and is further connected to the second enclosure <NUM> only after being squeezed by the second enclosure <NUM>. However, because the first elastic component <NUM> extends out of the first enclosure <NUM>, in the folding process of the electronic device, a side of the first elastic component <NUM> may come into contact with the second enclosure <NUM> first, and it is possible that the first elastic component <NUM> can only prevent the electronic device from being folded and cannot be elastically deformed normally. Therefore, an edge of the first elastic component <NUM> first coming into contact with the second enclosure <NUM> needs to be provided with a slope that can provide guidance, so that the first elastic component <NUM> slides and comes into contact with the second enclosure <NUM> through the slope when the electronic device is folded and an end portion of the first elastic component <NUM> abuts against the second enclosure <NUM>. Further, the first elastic component <NUM> can be elastically deformed successfully, and is elastically in contact with and connected to the second enclosure <NUM>. Therefore, as shown in <FIG>, and <FIG>, a side of the first elastic component <NUM> close to the second enclosure <NUM> is provided with a guiding slope <NUM>. In the folding process of the electronic device, when the contact member <NUM> is in contact with the second enclosure <NUM>, the guiding slope <NUM> is configured to guide the first elastic component <NUM> to be elastically deformed toward an inner portion of the first enclosure <NUM>.

The first elastic component <NUM> may be disposed based on an actual requirement. Generally, an available space inside the electronic device is small and a plurality of other functional members need to be mounted to implement other required functions, for example, a processor, a camera, and a voice output. Therefore, a space reserved for the antenna is limited, and the first elastic component <NUM> may be disposed at a position close to the antenna. As shown in <FIG>, the first enclosure <NUM> is articulated with the second enclosure <NUM> through an articulated shaft <NUM>. The first elastic component <NUM> is disposed on a side of the first enclosure <NUM> far away from the articulated shaft <NUM>. When the first enclosure and the second enclosure are in the folded state, the first elastic component <NUM> is elastically deformed, and the first elastic component <NUM> may be communicated with a side of the second enclosure <NUM> far away from the articulated shaft <NUM>, to elastically and electrically connect the first enclosure <NUM> to the second enclosure <NUM>.

It should be noted that both the first enclosure <NUM> and the second enclosure <NUM> can be electrically conductive. The first elastic component <NUM> elastically and electrically connects the first enclosure <NUM> to the second enclosure <NUM>, so that the first enclosure <NUM> may be communicated with the second enclosure <NUM> through the first elastic component <NUM>.

In addition, refer to <FIG> and <FIG>. If the first elastic component <NUM> is disposed on a side of the first enclosure <NUM> far away from the articulated shaft <NUM>, when the first enclosure and the second enclosure are in the folded state, two opposite side plates of the first enclosure <NUM> and the second enclosure <NUM> may be separately connected, to be specific, may be connected to the first elastic component <NUM> and the articulated shaft <NUM>. In this way, if the position of the antenna is closer to the articulated shaft <NUM>, the antenna may be communicated with the first enclosure <NUM> and the second enclosure <NUM> through the articulated shaft <NUM>, and a grounding path is shorter. If the position of the antenna is closer to the first elastic component <NUM>, the antenna may be communicated with the first enclosure <NUM> and the second enclosure <NUM> through the first elastic component <NUM>, and a grounding path is shorter.

When the first enclosure and the second enclosure are in the folded state, an end of the contact member <NUM> is in contact with and connected to the second enclosure <NUM>. In this case, the first enclosure <NUM> may be communicated with the second enclosure <NUM> by using a connection relationship between the elastic mechanical part <NUM>, the contact member <NUM>, and the first enclosure <NUM>. Certainly, another implementation may alternatively be used. For example, as shown in <FIG> and <FIG>, an elastomer <NUM> is fastened to the first elastic component <NUM>, and an elastic free end of the elastomer <NUM> is slidably and elastically in contact with and connected to the first enclosure <NUM>. To ensure a stable electrical connection between the first enclosure <NUM> and the second enclosure <NUM>, the elastomer <NUM> is disposed. An end of the elastomer <NUM> is fastened to the first elastic component <NUM>, and another end is the elastic free end and is slidably and elastically in contact with and connected to the first enclosure <NUM>. When the first elastic component <NUM> is deformed, the first elastic component <NUM> undergoes an elastic deformation toward the inner portion of the first enclosure <NUM>, and the elastomer <NUM> fastened to the first elastic component <NUM> moves with the deformation. In this process, the elastomer <NUM> is always slidably and elastically in contact with and connected to the first enclosure <NUM>. Therefore, the stable electrical connection between the first enclosure <NUM> and the second enclosure <NUM> can be ensured.

In the electronic device in this embodiment of this application, to implement a plurality of grounding paths, as shown in <FIG> and <FIG>, there are a plurality of first elastic components <NUM>, and the plurality of first elastic components <NUM> are sequentially disposed along a side edge of the first enclosure <NUM>. In this way, an elastic electrical connection between each first elastic component <NUM> and the second enclosure <NUM> may be a nearest grounding path of an antenna, and a plurality of antennas can be grounded through a shortest path in different positional conditions.

When the first enclosure <NUM> and the second enclosure <NUM> are folded together, as shown in <FIG>, if the left middle frame <NUM> and the right middle frame <NUM> have consistent shapes and sizes and are overlapped, when an elastic contact component is disposed at an end portion of the left middle frame <NUM>, the elastic contact component can be connected to the end portion of the right middle frame <NUM> only after thicknesses of the left middle frame <NUM> and the right middle frame <NUM> are eliminated. Further, the first elastic component <NUM> may need to be configured as a structure with a bending portion, or a bending structure may need to be disposed on the second enclosure <NUM>. However, such a solution does not facilitate production and assembly and is not beautiful enough. Therefore, as shown in <FIG> and <FIG>, a side edge of the second enclosure <NUM> is provided with a thickness cooperation portion <NUM>, a thickness of the thickness cooperation portion <NUM> is greater than or equal to a sum of the thicknesses of the first enclosure <NUM> and the second enclosure <NUM>, and the first elastic component <NUM> elastically and electrically connects the side edge of the first enclosure <NUM> to the thickness cooperation portion <NUM> of the second enclosure <NUM> when the first enclosure and the second enclosure are in the folded state. After the thickness cooperation portion <NUM> is disposed on the second enclosure <NUM>, the first elastic component <NUM> may be elastically and electrically connected to the thickness cooperation portion <NUM> when the first enclosure and the second enclosure are in the folded state. Further, no structure with a bending portion needs to be disposed inside the first elastic component <NUM>, nor a bending structure needs to be disposed on the second enclosure <NUM>. In addition, a shape of the thickness cooperation portion <NUM> may be configured based on the shape of the second enclosure <NUM> to ensure the appearance effect.

It should be noted that the thickness cooperation portion <NUM> may be integrated with the second enclosure <NUM> and is a part of the second enclosure <NUM>. As shown in <FIG> and <FIG>, the thickness cooperation portion <NUM> is a bumped structure disposed on the end portion of the second enclosure <NUM>. Optionally, the thickness of the thickness cooperation portion <NUM> is equal to a sum of the thicknesses of the first enclosure <NUM> and the second enclosure <NUM>. In this way, as shown in <FIG>, after the electronic device is folded, an outer surface of the first enclosure <NUM> is aligned with a surface of the thickness cooperation portion <NUM>, improving the appearance effect.

In the electronic device in this embodiment, when the first enclosure and the second enclosure are in the unfolded state, the first elastic component <NUM> may be completely located in the inner portion of the first enclosure. Specifically, as shown in <FIG>, <FIG>, <FIG>, and <FIG>, the first elastic component <NUM> is located in the inner portion of the first enclosure <NUM>, the second enclosure <NUM> is provided with a magnetic part in correspondence with the first elastic component <NUM>, and the magnetic part is disposed in correspondence with the first elastic component <NUM>. The first enclosure <NUM> is provided with a mounting groove <NUM>, the first end of the first elastic component <NUM> is connected to the first enclosure <NUM>, and the second end of the first elastic component <NUM> is located in the mounting groove <NUM> when the first enclosure <NUM> and the second enclosure <NUM> are in the unfolded state. When the first enclosure <NUM> and the second enclosure <NUM> are in the folded state, the second end of the first elastic component <NUM> is attracted by the magnetic part, the first elastic component <NUM> extends out of the mounting groove <NUM>, and the first electric-conductor and the second electric-conductor are electrically connected to the magnetic part through the first elastic component <NUM>.

In the electronic device in this embodiment, when the first enclosure <NUM> and the second enclosure <NUM> are in the unfolded state, as shown in <FIG>, the first elastic component <NUM> is located in the mounting groove <NUM> and can be well hidden to improve an appearance effect of the electronic device. In addition, this can be easily implemented in an attraction manner by using the magnetic part, no extra force needs to be applied, and the part cannot be damaged easily.

It should be noted that <FIG> and <FIG> are both schematic diagrams of the structure in the unfolded state. The first elastic component <NUM> in <FIG> is shown in perspective merely for ease of identifying the position of the first elastic component <NUM>. An actual appearance of the electronic device in this embodiment is shown in <FIG>. <FIG> is a schematic diagram of a structure in the folded state.

The first elastic component <NUM> may be implemented in a plurality of manners, provided that the first elastic component <NUM> can be elastically deformed and can connect the first enclosure <NUM> to the second enclosure <NUM>. For ease of implementation, the first elastic component <NUM> may include an elastic mechanical part <NUM> and a contact member <NUM>. The elastic mechanical part <NUM> is configured to be elastically deformed under a force and generate an elastic force in a direction opposite to a force bearing direction. The contact member <NUM> is configured to connect to and come into contact with the second enclosure <NUM>. Specifically, as shown in <FIG>, and <FIG>, the first elastic component <NUM> includes an elastic mechanical part <NUM> and a contact member <NUM>, a first end of the elastic mechanical part <NUM> is the first end of the first elastic component <NUM> and is disposed in the mounting groove <NUM>, the first end of the elastic mechanical part <NUM> is connected to the first enclosure <NUM>, a second end of the elastic mechanical part <NUM> is connected to a first end of the contact member <NUM>, and a second end of the contact member <NUM> is the second end of the first elastic component <NUM> and is located in the mounting groove <NUM>. In this way, the two ends of the elastic mechanical part <NUM> are respectively connected to the first enclosure <NUM> and the contact member <NUM>. When the first enclosure and the second enclosure are in the folded state, the contact member <NUM> is attracted by the magnetic part of the second enclosure <NUM>, and the elastic mechanical part <NUM> is elastically deformed, so that the contact member <NUM> can move toward the second enclosure <NUM> to come into contact with and connect to the second enclosure <NUM>.

In the solution in which the first elastic component <NUM> is completely located in the mounting groove <NUM> when the first enclosure and the second enclosure are in the unfolded state, the first elastic component <NUM> is attracted by the magnetic part when the first enclosure and the second enclosure are in the folded state. To ensure normal elastic contact, the first elastic component <NUM> may be implemented in a plurality of manners. For example, as shown in Embodiment <NUM> and <FIG>, a first end of the elastic mechanical part <NUM> is fixedly connected to and abuts against the first enclosure <NUM>, and another end of the elastic mechanical part <NUM> is fixedly connected to and abuts against the contact member <NUM>. A fixed connection manner includes, but is not limited to, a buckle connection, welding, riveting, or the like.

Alternatively, a first end of the elastic mechanical part <NUM> abuts against and is connected to the first enclosure <NUM>, and another end of the elastic mechanical part <NUM> abuts against and is connected to the contact member <NUM>.

In this case, because the two ends of the elastic mechanical part <NUM> are not fastened, a specific position and an expansion direction of the elastic mechanical part <NUM> need to be considered. Specifically, as shown in <FIG>, and <FIG>, the elastic mechanical part <NUM> is a spring, the first elastic component <NUM> further includes a spring sleeve <NUM> configured to accommodate the spring, the contact member <NUM> is provided with an accommodation groove <NUM>, the elastic mechanical part <NUM> is located in the accommodation groove <NUM>, the spring sleeve <NUM> is fixedly connected to the first enclosure <NUM>, an end of the spring sleeve <NUM> facing toward an inner portion of the first enclosure <NUM> has an opening, and an end of the spring extends out of the opening of the spring sleeve <NUM> and is connected to an inner wall of the accommodation groove <NUM>.

It should be noted that another specific structure and disposing manner are basically the same those in Embodiment <NUM>. In addition, in the solution in this embodiment, the first elastic component <NUM> is attracted by the magnetic part and extends out of the first enclosure <NUM>. Therefore, as shown in <FIG> and <FIG>, a slope <NUM> may or may not be disposed.

In the descriptions of this specification, the specific features, structures, materials, or characteristics may be combined in an appropriate manner in any one or more of the embodiments or examples.
