Patent Description:
This application relates to the technical field of shooting elements, and in particular to an electronic device with a front camera.

A minimum lens black edge of a front camera under a screen of an electronic terminal device is pursued in the current industry, to reduce an impact of the lens black edge on user's vision and increase a screen-to-body ratio of the electronic device. The lens black edge is usually limited by a gap size between a lens and a camera hole. A larger gap size between the lens and the camera hole indicates a wider lens black edge. This causes poorer visual experience for a user and a smaller display region of the screen.

For a front camera assembling structure in a related technology, a position at which a lens is installed within a camera hole is determined by a limiting groove on a middle frame and an outer wall of a camera body. This causes a plurality of parts associated and assembled between the lens and the camera hole, a long size chain, and a large cumulative tolerance that is finally formed. Therefore, an aperture of the camera hole is to be designed to be relatively large, to meet eccentricity of the lens in the camera hole.

However, a relatively large camera hole increases a gap size between the camera hole and the lens. Further, an impact of a lens black edge on user's vision cannot be reduced, and it is difficult to increase a screen-to-body ratio of an electronic device. In addition, matching and installation of the limiting groove on the middle frame and the outer wall of the camera body increases difficulties in processing and assembling the front camera. <CIT> discloses a terminal device with a camera module mounted using adhesive and a frame. <CIT> discloses a terminal device featuring a display screen with through-holes for integrated camera modules. <CIT> discloses a camera module installation structure with elastic limiters for attachment. <CIT> discloses an electronic device assembly method including dust-proofing using cushioning materials.

This application is intended to provide a front camera assembling method and assembling structure, and an electronic device. After a lens and a camera hole are accurately positioned by using a visual positioning system, a camera body is fastened to a middle frame, to reduce a quantity of parts associated and assembled between the lens and the camera hole to the minimum extent, shorten a size chain to the minimum extent, and an aperture of the camera hole is further designed to be small. Therefore, a gap size between the camera hole and the lens is reduced, an impact of a lens black edge on user's vision is reduced, and a screen-to-body ratio of the electronic device is increased. In addition, processing precision of an upper limiting groove on the middle frame and an outer wall of the camera body may not be considered, and a precision requirement for installing the middle frame onto a touchscreen is also reduced, reducing overall difficulties in processing and assembling the front camera.

According to a first aspect, this application provides a front camera assembling method. The method includes:.

In the front camera assembling method provided in this application, after the lens and the camera hole are accurately positioned by using the visual positioning system, the camera body is fastened to the middle frame. In an entire assembly process, only an appearance tolerance of the lens, a tolerance of the camera hole, and an assembly tolerance of the visual positioning system need to be considered, to reduce a quantity of parts associated and assembled between the lens and the camera hole to the minimum extent, shorten a size chain to the minimum extent, and achieve a minimum cumulative tolerance, and an aperture of the camera hole may be further designed to be small. Therefore, a gap size between the camera hole and the lens is reduced, an impact of a lens black edge on user's vision is reduced, and a screen-to-body ratio of the electronic device is increased.

In a related technology, a gap size between the camera hole and the lens is usually between <NUM> and <NUM>. In this application, the gap size between the camera hole and the lens may be approximately <NUM>. This can reduce the impact of the lens black edge on user's vision.

In addition, the front camera assembling method provided in this application further has advantages of low processing and assembling difficulties, which is specifically described as follows. In the related technology, the limiting groove not only plays a role in fastening the camera body, but also plays a role in positioning the lens. Therefore, a requirement for size precision of the limiting groove and a requirement for size precision of an outer wall of the camera body are relatively high, and a requirement for installation precision of installing the middle frame onto the touchscreen is also relatively high. In contrast, for the accommodation groove and the camera body in this application, the lens and the camera hole are directly accurately positioned by using the visual positioning system, and the accommodation groove plays a role in only accommodating the camera body. Therefore, a requirement for size precision of the accommodation groove and a requirement for size precision of the outer wall of the camera body are relatively low. A size of the accommodation groove only needs to meet a centering adjustment allowance of the lens and the camera hole. In addition, a requirement for installation precision of installing the middle frame onto the touchscreen is also relatively low. Therefore, overall difficulties in processing and assembling the front camera are reduced.

In a possible design, a step of the fastening the camera body in the accommodation groove includes:
bonding and fastening the camera body in the accommodation groove.

Optionally, the camera body and the accommodation groove may be bonded on a side wall or a bottom wall of the accommodation groove.

Optionally, when the camera body is bonded to a groove wall of the accommodation groove, an adhesive or a double-sided adhesive may be used.

Optionally, the camera body is bonded to the accommodation groove in two implementations. In a first implementation, the adhesive or the double-sided adhesive is affixed to a bonding position of the camera body and/or the accommodation groove in advance, and then the camera body is bonded to the groove wall of the accommodation groove when the lens and the camera hole are disposed in a centering manner by using the visual positioning system. In a second implementation, after the lens and the camera hole are disposed in a centering manner by using the visual positioning system, a robotic arm of the visual positioning system is kept motionless, and the adhesive is injected into a gap between the camera body and the accommodation groove by using a glue dispensing device.

In a possible design, a step of the moving the camera body by using a visual positioning system, to enable the lens to extend into the camera hole through the hole channel and to be disposed in a centering manner, and fastening the camera body in the accommodation groove includes:.

The camera support is fastened to the middle frame, to fasten the camera body in the accommodation groove. This fastening manner is implemented on the camera support and the middle frame. This may prevent direct contact with the camera body, preventing damage to the camera body during assembly and reducing material loss in an assembling phase. In addition, in a material loading phase, when the visual positioning system picks up the camera body, a sucked or clamped object is also the camera support. This also prevents direct contact with the camera body, and can effectively prevent damage to the camera body during material transfer, and further reduce material damage.

Optionally, the camera support is fastened to the camera body in a variety of manners, such as bonding by using the adhesive, soldering, snap-fitting, or connection by using the fastener.

In a possible design, a step of the fastening the camera body to a camera support includes:
bonding and fastening the camera body in an accommodation housing formed by a middle part that is of the camera support and that is convex.

By bonding and fastening the camera body in the accommodation housing, the accommodation housing may protect a part that is of the camera body and that is exposed out of the accommodation groove well, to prevent the camera body from being damaged due to a hit by another component during assembly.

In a possible design, a step of the fastening the camera support to the middle frame includes:
bonding and fastening the camera support to the middle frame.

The camera body may be fastened to the middle frame more firmly by using an adhesive without using another connection structure. This may improve integrity of a front camera assembling structure. In addition, size precision of another connection structure may not be considered when the adhesive is used for bonding, reducing processing and assembling difficulties.

In a possible design, two ends of the camera support are provided with first installation holes, the middle frame is correspondingly provided with second installation holes, and a step of the fastening the camera support to the middle frame includes:
disposing fasteners in the first installation hole and the second installation hole to fasten the camera support to the middle frame.

The camera support and the middle frame are locked by using the fasteners, helping to enable the front camera to be disassembled and repaired, and reassembled and reused.

After the camera support and the middle frame are bonded and pre-fastened, the camera support and the middle frame may be moved out of a position of the visual positioning system as a whole, and then locking by using the fasteners is performed at another position. This can improve efficiency of disposing in a centering manner by using the visual positioning system, and prevent the camera support and the middle frame from occupying the visual positioning system for a long time, reducing assembly efficiency. In addition, the camera support and the middle frame are bonded both by using an adhesive and connected by using the fasteners. This can ensure adequate connection strength between the camera support and the middle frame. To sum up, this embodiment has advantages of high assembly efficiency and a good anti-seismic effect.

Optionally, the fastener may be a screw or pin.

Specifically, the fastener is a screw, and a hole wall of the second installation hole is provided with a thread fitting the screw. When the screw is screwed in the second installation hole, a head of the screw is pressed at an orifice of the first installation hole.

Specifically, when the fastener is a pin, the second installation hole and the pin are in interference fit. When the pin is inserted into the second installation hole, a head of the pin is pressed at an orifice of the first installation hole.

In a possible design, a middle part of the camera support is concave to form a receiving groove, and a bottom groove wall of the receiving groove is provided with an avoidance hole, and a step of the fastening the camera body to a camera support includes:
enabling the lens to pass through the avoidance hole, and then bonding and fastening the camera body in the receiving groove.

In a possible design, a step of the fastening the camera support to the middle frame includes:
bonding and fastening an outer side of a groove wall of the receiving groove in the accommodation groove.

Optionally, a size of the outer side of the groove wall of the receiving groove is less than a size of the accommodation groove. This enables the receiving groove to be displaced in a horizontal direction in the accommodation groove, enabling the camera support to have an adjustment allowance in the horizontal direction relative to the middle frame when the lens and the camera hole are adjusted in a centering manner.

After the camera support and the middle frame are bonded and pre-fastened, the camera support and the middle frame may be moved out of a position of the visual positioning system as a whole, and then locking by using the fasteners is performed at another position. This can improve efficiency of disposing in a centering manner by using the visual positioning system, and prevent the camera support and the middle frame from occupying the visual positioning system for a long time, reducing assembly efficiency. In addition, in this embodiment, the camera support and the middle frame are bonded both by using an adhesive and connected by using the fastener. This can ensure adequate connection strength between the camera support and the middle frame. In addition, because the camera support is fastened to the middle frame in an embedding manner, connection strength between the camera support and the middle frame is further increased.

According to a second aspect, this application provides a front camera assembling structure. The structure includes:.

For the front camera assembling structure provided in this application, an accommodation groove whose size meets a requirement for adjusting the lens and the camera hole at the middle frame in a centering manner. After the lens and the camera hole are accurately positioned by using a visual positioning system, the camera body is fastened in the accommodation groove, to reduce a quantity of parts associated and assembled between the lens and the camera hole to the minimum extent, shorten a size chain to the minimum extent, and achieve a minimum cumulative tolerance, and an aperture of the camera hole is further designed to be small. Therefore, a gap size between the camera hole and the lens is reduced, an impact of a lens black edge on user's vision is reduced, and a screen-to-body ratio of the electronic device is increased.

In addition, the accommodation groove in this application plays a role in only accommodating the camera body, and does not play a role in positioning the lens in the camera hole. Therefore, in this application, a requirement for size precision of the accommodation groove is relatively low, and the size of the accommodation groove only needs to meet a centering adjustment allowance of the lens and the camera hole. In addition, requirements for size precision of an outer wall of the camera body and installation precision of installing the middle frame onto the touchscreen are also relatively low. Therefore, difficulties in processing and assembling the front camera are generally reduced.

In a possible design, the assembling structure further includes:
a camera support, where the camera body is fastened to the middle frame by using the camera support.

Optionally, the camera support may be a flat plate structure, a housing structure, or a frame structure.

In a possible design, a middle part of the camera support is provided with a convex accommodation housing, and the camera body is fastened in the accommodation housing.

This enables the camera support to better protect the camera body, preventing the camera body from being damaged due to hit by another component during assembly.

In a possible design, edges of two ends of the camera support include inwardly flanged edges, and an adhesive is disposed on inner sides of the inwardly flanged edges to bond and fasten the camera support to the middle frame.

The inwardly flanged edge mainly has two functions. A first function is limiting an installation depth of the lens. A height of the inwardly flanged edge can determine a depth at which the lens extends into the camera hole, to increase precision of assembling the front camera. A second function is preventing the adhesive from spilling. The inwardly flanged edges leave space by supporting between the camera support and the middle frame. The space can accommodate the adhesive, to prevent the adhesive from being squeezed and spilling out of a gap between the camera support and the middle frame when the camera support and the middle frame are pressed.

In a possible design, the inwardly flanged edges are disposed to be half-circled on the edges of the ends of the camera support to surround the adhesive.

Therefore, the adhesive is surrounded, and the adhesive is further prevented from spilling.

In a possible design, two ends of the camera support are provided with first installation holes, the middle frame is provided with second installation holes corresponding to the first installation holes, and fasteners are disposed in the first installation hole and the second installation hole to fasten the camera support to the middle frame.

In a possible design, an aperture of the first installation hole is larger than an aperture of the second installation hole, to enable the camera support to have an adjustment allowance relative to the middle frame.

Because the aperture of the first installation hole is larger than the aperture of the second installation hole, the first installation hole can deviate relative to the second installation hole within a specific range. Therefore, when the lens and the camera hole are adjusted in a centering manner, the camera support has an adjustment allowance relative to the middle frame in a horizontal direction.

Optionally, an elastic buffer is disposed between the camera body and the middle frame, to buffer vibration and prevent the lens from being hit. In addition, the elastic buffer further has sealing and dust-proof functions, to prevent affecting lighting quality because dust and the like enter the camera.

Optionally, the elastic buffer may be a buffer foam, or may be made of another soft and elastic material. The elastic buffer may not be disposed.

In a possible design, a heat conductive agent is filled in a gap between the accommodation housing and the camera body.

The heat conductive agent may effectively fill the gap between the accommodation housing and the camera body, reduce heat resistance, improve a capability of heat conduction from the camera body to the accommodation housing, and make heat conduction more smooth and fast.

Optionally, the accommodation housing is a metal housing. In addition to being configured to protect the camera body, in this embodiment, the accommodation housing further has a heat conduction function and a shielding function.

In a possible design, a middle part of the camera support is provided with a concave receiving groove, a bottom groove wall of the receiving groove is provided with an avoidance hole for avoiding the lens, the camera body is fastened in the receiving groove, and an outer side of a groove wall of the receiving groove is fastened in the accommodation groove.

In a possible design, a size of an outer side of a groove wall of the receiving groove is smaller than a size of the accommodation groove, to enable the camera support to have an adjustment allowance relative to the middle frame.

Optionally, an error-proof mechanism is provided on the camera support and the camera body.

When the camera support and the camera body are assembled, assembly efficiency and precision can be improved.

According to a third aspect, this application provides an electronic device. The electronic device includes the foregoing front camera assembling structure.

Optionally, the electronic device is a mobile phone, and the electronic device may alternatively be any one of a notebook computer, a tablet computer, and an electronic watch.

Because the foregoing front camera assembling structure is used for the electronic device in this application, the lens black edge of the front camera of the electronic device is smaller, the screen-to-body ratio is higher, and requirements for size precision and installation precision of parts are also relatively low, reducing overall difficulties in processing and assembling the electronic device and reducing manufacturing costs.

<FIG> is a schematic diagram of an electronic device in a related technology. <FIG> is a schematic diagram of a front camera in the related technology.

As shown in <FIG>, a minimum lens black edge <NUM> of a front camera under a screen of an electronic terminal device is pursued in the current industry, to reduce an impact of the lens black edge <NUM> on user's vision and increase a screen-to-body ratio of the electronic device.

<FIG> is a sectional view of <FIG> in an A-A direction. As shown in <FIG>, the lens black edge <NUM> is usually limited by a gap size L between a lens <NUM> and a camera hole <NUM>. As the gap size L between the lens <NUM> and the camera hole <NUM> is larger, the lens black edge <NUM> is wider. This causes poorer visual experience for a user and a smaller display region of the screen. Therefore, how to reduce the gap size L between the lens <NUM> and the camera hole <NUM> is an effective means for reducing or even eliminating the lens black edge <NUM>. However, for a current front camera assembling structure, the gap size L between the lens <NUM> and the camera hole <NUM> cannot be minimized. Specific reasons are as follows.

<FIG> is a schematic diagram of a front camera assembling structure in the related technology. As shown in <FIG>, a middle frame <NUM> is provided with a limiting groove <NUM> configured to limit a camera body <NUM>, and the camera body <NUM> is directly clamped in and fastened in the limiting groove <NUM>. When the camera body <NUM> is installed in position, the lens <NUM> just extends into the camera hole <NUM>. It can be learned that a position at which the lens <NUM> is installed in the camera hole <NUM> is determined by the limiting groove <NUM> on the middle frame <NUM> and an outer wall of the camera body <NUM>. This causes a plurality of parts associated and assembled between the lens <NUM> and the camera hole <NUM> and a long size chain. A touchscreen <NUM> is used as an example. The touchscreen <NUM> is a multilayer stacked structure and includes four or five size chains, and there are more than ten size chains between the lens <NUM> and the camera hole <NUM>, resulting in a large cumulative tolerance that is finally formed. Therefore, an aperture of the camera hole <NUM> is to be designed to be relatively large, to meet eccentricity of the lens <NUM> in the camera hole <NUM>.

However, a relatively large camera hole increases the gap size L between the camera hole <NUM> and the lens <NUM>, so that an impact of the lens black edge <NUM> on the user's vision cannot be reduced, and it is difficult to increase the screen-to-body ratio of the electronic device.

In addition, in the front camera assembling structure in an original related technology, to ensure installation precision of the lens <NUM> in the camera hole <NUM>, a requirement for size precision of the lens <NUM> and the camera hole <NUM> is to be high. In addition, because installation is performed by matching the limiting groove <NUM> on the middle frame <NUM> and the outer wall of the camera body <NUM>, processing precision of the limiting groove <NUM> on the middle frame <NUM> and processing precision of the outer wall of the camera body <NUM> are to be high, and a requirement for precision of installing the middle frame <NUM> onto the touchscreen <NUM> is also to be high. Generally, difficulties in processing and assembling the front camera are increased.

Therefore, to resolve the foregoing technical problem, this application provides a front camera assembling method and assembling structure, and an electronic device. After the lens <NUM> and the camera hole <NUM> are accurately positioned by using a visual positioning system, the camera body <NUM> is fastened to the middle frame <NUM>, to reduce a quantity of parts associated and assembled between the lens <NUM> and the camera hole <NUM> to the minimum extent, shorten a size chain to the minimum extent, and achieve a minimum cumulative tolerance, and an aperture of the camera hole <NUM> is further designed to be small. Therefore, a gap size L between the camera hole <NUM> and the lens <NUM> is reduced, an impact of a lens black edge <NUM> on user's vision is reduced, and a screen-to-body ratio of the electronic device is increased. In addition, the lens <NUM> and the camera hole <NUM> are directly accurately positioned, and then the camera body <NUM> and the middle frame <NUM> are fastened in another manner. Therefore, processing precision of an upper limiting groove <NUM> on the middle frame <NUM> and an outer wall of the camera body <NUM> may not be considered, and a precision requirement for installing the middle frame <NUM> onto the touchscreen <NUM> is also reduced, reducing overall difficulties in processing and assembling the front camera.

The front camera assembling method and assembling structure, and the electronic device provided in this application are described with reference to accompanying drawings.

<FIG> is a flowchart of an example of a front camera assembling method according to an embodiment of this application. <FIG> is a schematic diagram of an example of a front camera assembling method according to an embodiment of this application. (a) of <FIG> is a schematic diagram in which the middle frame <NUM> is not connected to the touchscreen <NUM>; (b) of <FIG> is a schematic diagram of the middle frame <NUM> that is connected to the touchscreen <NUM>, and the camera body <NUM>; (c) of <FIG> is a schematic diagram of disposing the lens <NUM> and the camera hole <NUM> in a centering manner; and (d) of <FIG> is a schematic diagram of connection between the camera body <NUM> and the middle frame <NUM>.

As shown in <FIG> and <FIG>, an embodiment of this application provides a front camera assembling method. The assembling method includes the following steps.

Step <NUM>: As shown in (a) of <FIG>, provide the middle frame <NUM>. The middle frame <NUM> is provided with an accommodation groove <NUM> that accommodates the camera body <NUM>. A size of the accommodation groove <NUM> meets a centering adjustment allowance that is of the lens <NUM> of the camera body <NUM> and the camera hole <NUM> of the touchscreen <NUM> and that exists when the camera body <NUM> is assembled.

Step <NUM>: As shown in (b) of <FIG>, assemble the middle frame <NUM> and the touchscreen <NUM> into an integral structure. The integral structure is provided with a hole channel <NUM> connecting the accommodation groove <NUM> and the camera hole <NUM>.

Step <NUM>: As shown in (c) and (d) of <FIG>, move the camera body <NUM> by using the visual positioning system (not shown in the figure), to enable the lens <NUM> to extend into the camera hole <NUM> through the hole channel <NUM> and to be disposed in a centering manner, and fasten the camera body <NUM> in the accommodation groove <NUM>.

It should be noted that the accommodation groove <NUM> in the embodiment of this application is different from a limiting groove <NUM> in the related technology. The accommodation groove <NUM> in the embodiment of this application plays a role in accommodating the camera body <NUM>, and is also configured to increase an overlapping area of the middle frame <NUM> and the camera body <NUM>, to coat more adhesive <NUM> for bonding and fastening, ensuring fastening strength between the camera body <NUM> and the middle frame <NUM>. A requirement for size precision of the accommodation groove <NUM> in the embodiment of this application is less strict than a requirement for size precision of the limiting groove <NUM> in the related technology, and a shape of the accommodation groove <NUM> just needs to approximately meet an appearance of the camera body <NUM>, to enable the camera body <NUM> to be smoothly disposed in the accommodation groove <NUM>. In addition, the size of the accommodation groove <NUM> just needs to meet an adjustment allowance for centering of the lens <NUM> and the camera hole <NUM>, to prevent interference to the camera body <NUM> by a groove wall of the accommodation groove <NUM> in centering of the lens <NUM> and the camera hole <NUM>. Therefore, compared with the limiting groove <NUM> with a strict size requirement in the related technology, a size requirement for the accommodation groove <NUM> in this embodiment is relatively low, and a processing difficulty is relatively low.

Optionally, the visual positioning system mainly includes a robotic arm, a suction apparatus, a visual positioning apparatus, and an XYθ mobile platform. A working process in the embodiment of this application is as follows. A driving mechanism drives the robotic arm to move, to enable the suction apparatus to move the camera body <NUM> out of an external transporting apparatus. In this case, a first visual positioning apparatus performs fast image processing on the lens <NUM> of the camera body <NUM>, records coordinate information of the lens <NUM>, and a second visual positioning apparatus performs fast image processing on the camera hole <NUM> of the touchscreen <NUM>, and records coordinate information of the camera hole <NUM>. After analyzing the coordinate information of the lens <NUM> and the coordinate information of the camera hole <NUM>, the first visual positioning apparatus gives feedback to the XY θ mobile platform. The suction apparatus, driven by the XYθ mobile platform, adjusts an initial position of the camera body <NUM>. The driving mechanism drives the robotic arm to move, to enable the suction apparatus to move the camera body <NUM> over the touchscreen <NUM>. The robotic arm drives the suction apparatus and the camera body <NUM> to fall, and extends the lens <NUM> into the camera hole <NUM>. Then the suction apparatus, driven by the XYθ mobile platform, adjusts a position of the camera body <NUM> slightly and accurately, to compensate for a coordinate error of the lens <NUM>, enabling the lens <NUM> and the camera hole <NUM> to be disposed in a centering manner.

Optionally, when sucking the camera body <NUM> from the external transporting apparatus, the suction apparatus may first move the camera body <NUM> to a position adjustment tool. The position adjustment tool adjusts the position of the camera body <NUM> approximately, to enable the camera body <NUM> to be initially positioned. Then the suction apparatus sucks the camera body <NUM> from the position adjustment tool. Therefore, a centering error may be greatly reduced, and installation precision of the camera body <NUM> may be further increased.

Optionally, when the lens <NUM> and the camera hole <NUM> are disposed in a centering manner by using the visual positioning system, the camera body <NUM> is fastened in the accommodation groove <NUM> in a variety of fastening manners. The camera body <NUM> may be directly bonded in the accommodation groove <NUM>, or the middle frame <NUM> is indirectly connected to the camera body <NUM> by using an additional component, such as a camera support <NUM> in a subsequent embodiment. The camera body <NUM> is pre-connected to the camera support <NUM>, and then the middle frame <NUM> is bonded to the camera support <NUM> or connected by using fasteners <NUM>. Refer to the following for more detailed description.

In the front camera assembling method provided in the embodiment of this application, after the lens <NUM> and the camera hole <NUM> are accurately positioned by using the visual positioning system, the camera body <NUM> is fastened to the middle frame <NUM>. In an entire assembly process, only an appearance tolerance of the lens <NUM>, a tolerance of the camera hole <NUM>, and an assembly tolerance of the visual positioning system need to be considered, tto reduce a quantity of parts associated and assembled between the lens <NUM> and the camera hole <NUM> to the minimum extent, shorten a size chain to the minimum extent, and achieve a minimum cumulative tolerance, and an aperture of the camera hole <NUM> may be further designed to be small. Therefore, a gap size between the camera hole <NUM> and the lens <NUM> is reduced, an impact of a lens black edge <NUM> on user's vision is reduced, and a screen-to-body ratio of the electronic device is increased.

In the related technology, the gap size L between the camera hole <NUM> and the lens <NUM> is usually between <NUM> and <NUM>. In the embodiment of this application, a gap size L' between the camera hole <NUM> and the lens <NUM> may be approximately <NUM>. This can reduce the impact of the lens black edge <NUM> on user's vision.

In addition, the embodiment of this application further has advantages of low processing and assembling difficulties. Specifically, in the related technology, the limiting groove <NUM> not only plays a role in fastening the camera body <NUM>, but also plays a role in positioning the lens <NUM>. Therefore, a requirement for size precision of the limiting groove <NUM> and a requirement for size precision of an outer wall of the camera body <NUM> are relatively high, and a requirement for installation precision of installing the middle frame <NUM> onto the touchscreen <NUM> is also relatively high. In contrast, for the accommodation groove <NUM> and the camera body <NUM> in the embodiment of this application, the lens <NUM> and the camera hole <NUM> are directly accurately positioned by using the visual positioning system, and the accommodation groove <NUM> plays a role in only accommodating the camera body <NUM>. Therefore, a requirement for size precision of the accommodation groove <NUM> and a requirement for size precision of the outer wall of the camera body <NUM> are low. A size of the accommodation groove <NUM> only needs to meet a centering adjustment allowance of the lens <NUM> and the camera hole <NUM>. In addition, a requirement for installation precision of installing the middle frame <NUM> onto the touchscreen <NUM> is also low. Therefore, overall difficulties in processing and assembling the front camera are reduced.

<FIG> is a flowchart of another example of the front camera assembling method according to an embodiment of this application.

As shown in <FIG>, in an embodiment provided in this application, the assembling method includes the following steps.

Step <NUM>: Provide the middle frame <NUM>.

Step <NUM>: Assemble the middle frame <NUM> and the touchscreen <NUM> into an integral structure.

Step <NUM>: Move the camera body <NUM> by using the visual positioning system, to enable the lens <NUM> to extend into the camera hole <NUM> and to be disposed in a centering manner, and bond and fasten the camera body <NUM> in an accommodation groove <NUM>.

Optionally, the camera body <NUM> and the accommodation groove <NUM> may be bonded on a side wall or a bottom wall of the accommodation groove <NUM>.

Optionally, when the camera body <NUM> is bonded to a groove wall of the accommodation groove <NUM>, an adhesive <NUM> or a double-sided adhesive may be used.

Optionally, the camera body <NUM> is bonded to the accommodation groove <NUM> in two implementations. In a first implementation, the adhesive <NUM> or the double-sided adhesive is affixed to a bonding position of the camera body <NUM> and/or the accommodation groove <NUM> in advance, and then the camera body <NUM> is bonded to the groove wall of the accommodation groove <NUM> when the lens <NUM> and the camera hole <NUM> are disposed in a centering manner by using the visual positioning system. In a second implementation, after the lens <NUM> and the camera hole <NUM> are disposed in a centering manner by using the visual positioning system, a robotic arm of the visual positioning system is kept motionless, and the adhesive <NUM> is injected into a gap between the camera body <NUM> and the accommodation groove <NUM> by using a glue dispensing device.

In this embodiment, the camera body <NUM> may be quickly and firmly fastened in the accommodation groove <NUM> by bonding, which is implemented easily.

As described above, the camera body <NUM> is fastened in the accommodation groove <NUM> in a variety of manners, and the camera body <NUM> may be fastened in the accommodation groove <NUM> by using an additional component. That is, in an embodiment provided in this application, in step <NUM>, before the visual positioning system is used, a camera support <NUM> is fastened to the camera body <NUM>, and the camera support <NUM> is fastened to the middle frame <NUM>, to achieve a purpose of fastening the camera body <NUM> in the accommodation groove <NUM>. Specific steps are as follows.

Step <NUM>: Fasten the camera body <NUM> to the camera support <NUM>.

Step <NUM>: Move the camera support <NUM> and the camera body <NUM> by using the visual positioning system, to enable the lens <NUM> to extend into the camera hole <NUM> through the hole channel <NUM> and to be disposed in a centering manner, and fasten the camera support <NUM> to the middle frame <NUM>, to enable the camera body <NUM> to be fastened in the accommodation groove <NUM>.

In this embodiment, the camera support <NUM> is fastened to the middle frame <NUM>, to fasten the camera body <NUM> in the accommodation groove <NUM>. In this fastening manner, implementation objects are the camera support <NUM> and the middle frame <NUM>, and direct contact with the camera body <NUM> may be prevented, to prevent damage to the camera body <NUM> during assembly and reduce material damage in an assembling phase.

In addition, in a material loading phase, when the visual positioning system picks up the camera body <NUM>, a sucked or clamped object is also the camera support <NUM>. This also prevents direct contact with the camera body <NUM>, and can effectively prevent damage to the camera body <NUM> during material transfer, and further reduce material damage.

Optionally, the camera support <NUM> is fastened to the camera body <NUM> in a variety of manners, such as bonding by using the adhesive <NUM>, soldering, snap-fitting, or connection by using fasteners <NUM>.

Optionally, the camera support <NUM> is fastened to the middle frame <NUM> in a variety of manners, such as bonding by using the adhesive <NUM>, soldering, or connection by using the fasteners <NUM>.

As described above, the camera body <NUM> and the camera support <NUM> may be bonded by using the adhesive <NUM>. A specific implementation is shown in an embodiment provided in this application. The middle part of the camera support <NUM> is provided with a convexly formed accommodation housing <NUM>. Based on the design, a step of fastening the camera body <NUM> to the camera support <NUM> specifically includes:
bonding and fastening the camera body <NUM> in the convexly formed accommodation housing <NUM> in the middle of the camera support <NUM>.

In this embodiment, by bonding and fastening the camera body <NUM> in the accommodation housing <NUM>, the accommodation housing <NUM> may protect a part that is of the camera body <NUM> and that is exposed out of the accommodation groove <NUM>, to prevent the camera body <NUM> from being damaged due to a hit by another component during assembly. In addition, the camera body <NUM> may be fastened to the camera support <NUM> more firmly by bonding the adhesive <NUM>, which is implemented easily.

<FIG> is a flowchart of another example of the front camera assembling method according to an embodiment of this application. <FIG> is a schematic diagram of another example of the front camera assembling method according to an embodiment of this application. (a) of <FIG> is a schematic diagram in which the camera body <NUM> is not connected to the camera support <NUM>; (b) of <FIG> is a schematic diagram in which the middle frame <NUM> is not connected to the touchscreen <NUM>; (c) of <FIG> is a schematic diagram of connection between the camera body <NUM> and the camera support <NUM> and connection between the middle frame <NUM> and the touchscreen <NUM>; (d) of <FIG> is a schematic diagram in which the lens <NUM> and the camera hole <NUM> are disposed in a centering manner; and (e) of <FIG> is a schematic diagram of connection between the camera support <NUM> and the middle frame <NUM>.

As described above, the camera support <NUM> may be bonded to the middle frame <NUM> by using an adhesive <NUM>. A specific implementation is shown in an embodiment provided in this application. As shown in <FIG> and <FIG>, the assembling method includes the following steps.

Step <NUM>: As shown in (a) of <FIG>, provide the middle frame <NUM>.

Step <NUM>: As shown in (b) and (c) of <FIG>, assemble the middle frame <NUM> and the touchscreen <NUM> into an integral structure.

Step <NUM>: As shown in (a) and (c) of <FIG>, bond and fasten the camera body <NUM> in an accommodation housing <NUM> formed by a middle part that is of the camera support <NUM> and that is convex.

Step <NUM>: As shown in (d) and (e) of <FIG>, move the camera support <NUM> and the camera body <NUM> by using the visual positioning system, to enable the lens <NUM> to extend into the camera hole <NUM> through a hole channel <NUM> and to be disposed in a centering manner, and bond and fasten the camera support <NUM> to the middle frame <NUM>, to enable the camera body <NUM> to be fastened in an accommodation groove <NUM>.

In this embodiment, the camera body <NUM> and the middle frame <NUM> may be fastened more firmly by using an adhesive <NUM> without using another connection structure (for example, a fastener <NUM>). This may improve integrity of a front camera assembling structure. In addition, size precision of another connection structure may not be considered when the adhesive <NUM> is used for bonding, reducing processing and assembling difficulties.

Optionally, the camera body <NUM> is bonded to the middle frame <NUM> in two implementations. In a first implementation, the adhesive <NUM> is coated to a bonding position of the camera body <NUM> and/or the middle frame <NUM> in advance, and then the camera body <NUM> is bonded to the middle frame <NUM> when the lens <NUM> and the camera hole <NUM> are disposed in a centering manner by using the visual positioning system. In a second implementation, after the lens <NUM> and the camera hole <NUM> are disposed in a centering manner by using the visual positioning system, a robotic arm of the visual positioning system is kept motionless, and the adhesive <NUM> is injected into a gap of a bonding position between the camera body <NUM> and the middle frame <NUM> by using a glue dispensing device.

As described above, the camera support <NUM> and the middle frame <NUM> may be locked by using the fasteners <NUM>. A specific implementation is shown in an embodiment provided in this application. Two ends of the camera support <NUM> are provided with first installation holes <NUM>, and the middle frame <NUM> is provided with second installation holes <NUM> corresponding to the first installation holes <NUM>. Based on the design, as shown in <FIG>, the assembling method includes the following steps.

Step <NUM>: Bond and fasten the camera body <NUM> in an accommodation housing <NUM> formed by a middle part that is of the camera support <NUM> and that is convex.

Step <NUM>: Move the camera support <NUM> and the camera body <NUM> by using the visual positioning system, to enable the lens <NUM> to extend into the camera hole <NUM> through a hole channel <NUM> and to be disposed in a centering manner, and dispose the fasteners <NUM> in the first installation hole <NUM> and the second installation hole <NUM> to fasten the camera support <NUM> to the middle frame <NUM>, to enable the camera body <NUM> to be fastened in an accommodation groove <NUM>.

In this embodiment, the camera support <NUM> and the middle frame <NUM> are locked by using the fasteners <NUM>, helping to enable the front camera to be disassembled and repaired, and reassembled and reused.

<FIG> is a flowchart of another example of the front camera assembling method according to an embodiment of this application. <FIG> is a schematic diagram of another example of the front camera assembling method according to an embodiment of this application. (a) of <FIG> is a schematic diagram in which the camera body <NUM> is not connected to the camera support <NUM>; (b) of <FIG> is a schematic diagram in which the middle frame <NUM> is not connected to the touchscreen <NUM>; (c) of <FIG> is a schematic diagram of connection between the camera body <NUM> and the camera support <NUM> and connection between the middle frame <NUM> and the touchscreen <NUM>; (d) of <FIG> is a schematic diagram in which the lens <NUM> and the camera hole <NUM> are disposed in a centering manner; (e) of <FIG> is a schematic diagram of bonding and pre-fastening of the camera support <NUM> and the middle frame <NUM>; and (f) of <FIG> is a schematic diagram of locking of the camera support <NUM> and the middle frame <NUM> by using fasteners <NUM>.

In the foregoing embodiments, two manners in which the camera support <NUM> is bonded to the middle frame <NUM> by using the adhesive <NUM> or the fasteners <NUM>, to increase connection strength between the camera support <NUM> and the middle frame <NUM>, and bonding by using the adhesive <NUM> and connection by using the fasteners <NUM> may be implemented simultaneously. Specifically, as shown in <FIG> and <FIG>, in an embodiment provided in this application, the assembling method includes the following steps.

Step <NUM>: As shown in (d) and (e) of <FIG>, move the camera support <NUM> and the camera body <NUM> by using the visual positioning system, to enable the lens <NUM> to extend into the camera hole <NUM> through a hole channel <NUM> and to be disposed in a centering manner, and bond and pre-fasten the camera support <NUM> and the middle frame <NUM>.

Step <NUM>: As shown in (f) of <FIG>, dispose the fasteners <NUM> in a first installation hole <NUM> and a second installation hole <NUM>, to fasten the camera support <NUM> to the middle frame <NUM>, and to enable the camera body <NUM> to be fastened in an accommodation groove <NUM>.

In this embodiment, after the camera support <NUM> and the middle frame <NUM> are bonded and pre-fastened, the camera support <NUM> and the middle frame <NUM> may be moved out of a position of the visual positioning system as a whole, and then locking by using the fasteners <NUM> may be performed at another position. This can improve efficiency of disposing in a centering manner by using the visual positioning system, and prevent the camera support <NUM> and the middle frame <NUM> from occupying the visual positioning system for a long time, reducing assembly efficiency. In addition, in this embodiment, the camera support <NUM> and the middle frame <NUM> are bonded both by using an adhesive <NUM> and connected by using the fasteners <NUM>. This can ensure adequate connection strength between the camera support <NUM> and the middle frame <NUM>. To sum up, this embodiment has advantages of high assembly efficiency and a good anti-seismic effect.

As shown in (d) and (e) of <FIG>, in an embodiment provided in this application, an aperture of the first installation hole <NUM> is larger than an aperture of the second installation hole <NUM>, to enable the camera support <NUM> to have an adjustment allowance relative to the middle frame <NUM>.

In this embodiment, because the aperture of the first installation hole <NUM> is larger than the aperture of the second installation hole <NUM>, the first installation hole <NUM> can deviate relative to the second installation hole <NUM> within a specific range. When the lens <NUM> and the camera hole <NUM> are adjusted in a centering manner, a displacement of the camera support <NUM> relative to the middle frame <NUM> in a horizontal direction also has an adjustment allowance.

Optionally, the fastener <NUM> may be a screw or pin.

Specifically, when the fastener <NUM> is a screw, a hole wall of the second installation hole <NUM> is provided with a thread fitting the screw. When the screw is screwed in the second installation hole <NUM>, a head of the screw is pressed at an orifice of the first installation hole <NUM>.

Specifically, when the fastener <NUM> is a pin, the second installation hole <NUM> and the pin are in interference fit. When the pin is inserted into the second installation hole <NUM>, a head of the pin is pressed at the orifice of the first installation hole <NUM>.

The camera support <NUM> may be alternatively designed in another manner. For example, in another embodiment provided in this application, the camera support <NUM> is provided with a concave receiving groove <NUM>, and an avoidance hole <NUM> for avoiding the lens <NUM> is disposed at a bottom groove wall of the receiving groove <NUM>. Based on the design, a step of fastening the camera body <NUM> to the camera support <NUM> specifically include:
enabling the lens <NUM> to pass through the avoidance hole <NUM>, and then bonding and fastening the camera body <NUM> in the receiving groove <NUM>.

In addition, based on the foregoing design in which the camera support <NUM> is provided with the concave receiving groove <NUM>, in an embodiment provided in this application, the step of fastening the camera support <NUM> to the middle frame <NUM> specifically includes:
bonding and fastening an outer side of a groove wall of the receiving groove <NUM> in the accommodation groove <NUM>.

Optionally, a size of the outer side of the groove wall of the receiving groove <NUM> is less than a size of the accommodation groove <NUM>. This enables the receiving groove <NUM> to be displaced in a horizontal direction in the accommodation groove <NUM>, enabling the camera support <NUM> to have an adjustment allowance in the horizontal direction relative to the middle frame <NUM> when the lens <NUM> and the camera hole <NUM> are adjusted in a centering manner.

Based on the foregoing design in which the camera support <NUM> is provided with the concave receiving groove <NUM>, in an embodiment provided in this application, two ends of the camera support <NUM> are provided with the first installation holes <NUM>, and the middle frame <NUM> is provided with the second installation holes <NUM> corresponding to the first installation holes <NUM>. The step of fastening the camera support <NUM> to the middle frame <NUM> specifically includes:
disposing the fasteners <NUM> in the first installation hole <NUM> and the second installation hole <NUM> to fasten the camera support <NUM> to the middle frame <NUM>.

Optionally, the aperture of the first installation hole <NUM> is larger than the aperture of the second installation hole <NUM>, to enable the camera support <NUM> to have an adjustment allowance relative to the middle frame <NUM>.

As shown in <FIG> and <FIG>, in an embodiment provided in this application, the assembling method includes the following steps.

Step <NUM>: As shown in (a) and (c) of <FIG>, enable the lens <NUM> to pass through an avoidance hole <NUM>, and then bond and fasten the camera body <NUM> in a receiving groove <NUM>.

Step <NUM>: As shown in (d) and (e) of <FIG>, move the camera support <NUM> and the camera body <NUM> by using the visual positioning system, to enable the lens <NUM> to extend into the camera hole <NUM> through a hole channel <NUM> and to be disposed in a centering manner, and bond and pre-fasten an outer side of a groove wall of the receiving groove <NUM> in an accommodation groove <NUM>.

Step <NUM>: As shown in (f) of <FIG>, dispose the fasteners <NUM> in a first installation hole <NUM> and a second installation hole <NUM>, to fasten the camera support <NUM> to the middle frame <NUM>, and to enable the camera body <NUM> to be fastened in the accommodation groove <NUM>.

In this embodiment, after the camera support <NUM> and the middle frame <NUM> are bonded and pre-fastened, the camera support <NUM> and the middle frame <NUM> may be moved out of a position of the visual positioning system as a whole, and then locking by using the fasteners <NUM> may be performed at another position. This can improve efficiency of disposing in a centering manner by using the visual positioning system, and prevent the camera support <NUM> and the middle frame <NUM> from occupying the visual positioning system for a long time, reducing assembly efficiency. In addition, in this embodiment, the camera support <NUM> and the middle frame <NUM> are bonded both by using an adhesive <NUM> and connected by using the fasteners <NUM>. This can ensure adequate connection strength between the camera support <NUM> and the middle frame <NUM>. In addition, because the camera support <NUM> is fastened to the middle frame <NUM> in an embedding manner, connection strength between the camera support <NUM> and the middle frame <NUM> is further increased. To sum up, this embodiment also has advantages of high assembly efficiency and a good anti-seismic effect.

<FIG> is a sectional view of an example of a front camera assembling structure according to an embodiment of this application.

As shown in <FIG>, an embodiment of this application further provides a front camera assembling structure, including a camera body <NUM>, a touchscreen <NUM>, and a middle frame <NUM>.

The camera body <NUM> includes a lens <NUM> located at a front end.

The touchscreen <NUM> is provided with a camera hole <NUM> for accommodating the lens <NUM>.

The middle frame <NUM> is fastened to the touchscreen <NUM>. The middle frame <NUM> is provided with an accommodation groove <NUM> whose size meets a requirement for adjusting the lens <NUM> and the camera hole <NUM> in a centering manner. The accommodation groove <NUM> communicates with the camera hole <NUM> through a hole channel <NUM>, the camera body <NUM> is fastened in the accommodation groove <NUM>, and the lens <NUM> passes through the hole channel <NUM> and is disposed in the camera hole <NUM> in a centering manner.

In the front camera assembling structure provided in this application, when the middle frame <NUM> is provided with the accommodation groove <NUM> whose size meets a requirement for adjusting the lens <NUM> and the camera hole <NUM> in a centering manner, the lens <NUM> and the camera hole <NUM> may be accurately positioned by using the visual positioning system, and then the camera body <NUM> is fastened in the accommodation groove <NUM>, to reduce parts associated and assembled between the lens <NUM> and the camera hole <NUM> significantly, shorten a size chain significantly, and achieve a minimum cumulative tolerance, and an aperture of the camera hole <NUM> may be further designed to be small. Therefore, a gap size between the camera hole <NUM> and the lens <NUM> is reduced, an impact of a lens black edge <NUM> on user's vision is reduced, and the screen-to-body ratio of the electronic device is increased.

In addition, because the lens <NUM> and the camera hole <NUM> are accurately positioned by using the visual positioning system, the accommodation groove <NUM> in this embodiment of this application plays a role in only accommodating the camera body <NUM>, and does not play a role in positioning the lens <NUM> in the camera hole <NUM>. Therefore, in this application, a requirement for size precision of the accommodation groove <NUM> is relatively low, and the size of the accommodation groove <NUM> only needs to meet a centering adjustment allowance of the lens <NUM> and the camera hole <NUM>. In addition, requirements for size precision of an outer wall of the camera body <NUM> and installation precision of installing the middle frame <NUM> onto the touchscreen <NUM> are also relatively low. Therefore, difficulties in processing and assembling the front camera are generally reduced.

Optionally, the middle frame <NUM> is fastened to the camera body <NUM> in a variety of manners. The middle frame <NUM> may be directly bonded to the camera body <NUM>, or the middle frame <NUM> is indirectly connected to the camera body <NUM> by using an additional component, such as a camera support <NUM> in a following embodiment. The camera body <NUM> is pre-connected to the camera support <NUM>, and then the middle frame <NUM> is bonded to the camera support <NUM> or connected by using fasteners <NUM>. Refer to the following description for details.

As described above, the middle frame <NUM> and the camera body <NUM> may be directly bonded. That is, in this embodiment, the camera body <NUM> is bonded and fastened to the accommodation groove <NUM> by using an adhesive <NUM>. It should be especially noted that the accommodation groove <NUM> in this embodiment is different from a limiting groove <NUM> in the related technology. The accommodation groove <NUM> in this embodiment plays a role in only accommodating the camera body <NUM>, and is further configured to increase an overlapping area of the middle frame <NUM> and the camera body <NUM>, to enable the camera body <NUM> in the accommodation groove <NUM> to be in contact with the groove wall with an adequate contact area on which more adhesive <NUM> may be coated for bonding and fastening, ensuring fastening strength between the camera body <NUM> and the middle frame <NUM>. A size requirement for the accommodation groove <NUM> is not strict, and only a shape of the accommodation groove <NUM> needs to generally meet an appearance requirement for the camera body <NUM>, enabling the camera body <NUM> to be smoothly disposed in the accommodation groove <NUM>. Therefore, compared with the limiting groove <NUM> with a strict size requirement for processing in the related technology, a size requirement for the accommodation groove <NUM> in this embodiment is relatively low, and a processing difficulty is relatively low.

In this embodiment, the camera body <NUM> and the middle frame <NUM> may be fastened more firmly by using the adhesive <NUM> without using another connection structure. This may improve integrity of the electronic device. In addition, size precision of another connection structure may not be considered when the adhesive <NUM> is used for bonding, reducing processing and assembling difficulties.

Optionally, the adhesive <NUM> may be disposed in a groove bottom wall of the accommodation groove <NUM> in a pre-coating manner. Alternatively, after the camera body <NUM> is disposed in the accommodation groove <NUM>, the adhesive <NUM> may be injected into a gap between the camera body <NUM> and the groove wall of the accommodation groove <NUM> in a glue dispensing manner.

<FIG> is a sectional view of another example of the front camera assembling structure according to an embodiment of this application.

As shown in <FIG>, in an embodiment provided in this application, the assembling structure further includes:
a camera support <NUM>, separately fastened to the camera body <NUM> and the middle frame <NUM>, to enable the camera body <NUM> to be fastened to the middle frame <NUM> by using the camera support <NUM>.

As described above, the middle frame <NUM> and the camera body <NUM> may be indirectly connected by using an additional component. That is, in this embodiment, the camera support <NUM> is added between the camera body <NUM> and the middle frame <NUM>. The camera support <NUM> is first connected to the camera body <NUM>, and then the camera support <NUM> is connected to the middle frame <NUM>.

Specifically, the camera support <NUM> is bonded to the camera body <NUM> by using the adhesive <NUM>. This manner has advantages of fast assembly and a small structure.

Optionally, the camera support <NUM> is fastened to the middle frame <NUM> in a variety of manners, such as bonding by using the adhesive <NUM> or connection by using the fasteners <NUM>. Refer to the following embodiment for details.

Optionally, the camera body <NUM> is fastened to the middle frame <NUM> by using the camera support <NUM> in two manners. In a first manner, after the camera body <NUM> is connected to the middle frame <NUM>, the connection is further reinforced by using the camera support <NUM>. In a second manner, the camera body <NUM> is not connected to the middle frame <NUM>, and the camera body <NUM> relies only on a connection relationship between the camera support <NUM> and the middle frame <NUM>.

Optionally, the camera support <NUM> may be a flat plate structure, a housing structure, or a frame structure.

As shown in <FIG>, in an embodiment provided in this application, the camera support <NUM> is provided with a convex accommodation housing <NUM>, and the camera body <NUM> is fastened in the accommodation housing <NUM>.

As described above, the camera support <NUM> may be a housing structure, that is, in this embodiment, the camera support <NUM> is provided with the convex accommodation housing <NUM>, and the accommodation housing <NUM> surrounds an outside of the camera body <NUM>. This enables the camera support <NUM> to better protect the camera body <NUM>, preventing the camera body <NUM> from being damaged due to hit by another component during assembly.

In an embodiment provided in this application, edges of two ends of the camera support <NUM> include inwardly flanged edges <NUM>, and an adhesive <NUM> is disposed on inner sides of the inwardly flanged edges <NUM> to bond and fasten the camera support <NUM> to the middle frame <NUM>.

The inwardly flanged edges <NUM> in this embodiment mainly have two functions. A first function is limiting an installation depth of the lens <NUM>. A height of the inwardly flanged edge <NUM> can determine a depth at which the lens <NUM> extends into the camera hole <NUM>, to increase precision of assembling the front camera. A second function is preventing the adhesive <NUM> from spilling. The inwardly flanged edges <NUM> leave space by supporting between the camera support <NUM> and the middle frame <NUM>. The space can accommodate the adhesive <NUM>, to prevent the adhesive <NUM> from being squeezed and spilling out of a gap between the camera support <NUM> and the middle frame <NUM> when the camera support <NUM> and the middle frame <NUM> are pressed.

Based on the second function of the inwardly flanged edges <NUM>, to further prevent the adhesive <NUM> from spilling, in an embodiment provided in this application, the inwardly flanged edges <NUM> are disposed to be half-circled on the edges of the ends of the camera support <NUM>, to totally surround the adhesive <NUM>.

<FIG> is a schematic diagram of an example of a front camera assembling structure according to an embodiment of this application. <FIG> is an exploded view of the front camera assembling structure in <FIG>. <FIG> is an exploded view of the front camera assembling structure in <FIG> from another viewing angle. <FIG> is a sectional view in a B-B direction in <FIG>.

As shown in <FIG>, in an embodiment provided in this application, that a camera support <NUM> is connected to a middle frame <NUM> by using only fasteners <NUM> is specifically as follows: Two ends of the camera support <NUM> are provided with first installation holes <NUM>, the middle frame <NUM> is provided with second installation holes <NUM> corresponding to the first installation holes <NUM>, and the fasteners <NUM> are disposed in the first installation hole <NUM> and the second installation hole <NUM> to fasten the camera support <NUM> to the middle frame <NUM>.

As shown in <FIG>, in another embodiment provided in this application, bonding is reinforced by using the fasteners <NUM> after the camera support <NUM> is bonded to the middle frame <NUM>. Specifically, after the camera support <NUM> is bonded and pre-fastened to the middle frame <NUM> by using the adhesive <NUM>, the fasteners <NUM> are disposed in the first installation hole <NUM> and the second installation hole <NUM> to fasten the camera support <NUM> to the middle frame <NUM>.

In an embodiment provided in this application, an aperture of the first installation hole <NUM> is larger than an aperture of the second installation hole <NUM>, to enable the camera support <NUM> to have an adjustment allowance relative to the middle frame <NUM>.

In this embodiment, because the aperture of the first installation hole <NUM> is larger than the aperture of the second installation hole <NUM>, the first installation hole <NUM> can deviate relative to the second installation hole <NUM> within a specific range. Therefore, when the lens <NUM> and the camera hole <NUM> are adjusted in a centering manner, the camera support <NUM> has an adjustment allowance relative to the middle frame <NUM> in a horizontal direction.

As shown in <FIG> and <FIG>, in an embodiment provided in this application, an elastic buffer <NUM> is disposed between the camera body <NUM> and the middle frame <NUM>.

The elastic buffer <NUM> is disposed between the camera body <NUM> and the middle frame <NUM>, to buffer vibration and prevent the lens <NUM> from being hit. In addition, the elastic buffer <NUM> further has sealing and dust-proof functions, to prevent affecting lighting quality because dust and the like enter the camera.

Optionally, the elastic buffer <NUM> may be a buffer foam, or may be made of another soft and elastic material. In another embodiment, the elastic buffer <NUM> may not be disposed.

In an embodiment provided in this application, an accommodation housing <NUM> is a metal housing.

The accommodation housing <NUM> is configured to protect the camera body <NUM>. In addition, in this embodiment, when the accommodation housing <NUM> is the metal housing, the accommodation housing <NUM> further has a heat conduction function and a shielding function.

In addition, when the accommodation housing <NUM> is the metal housing, pick-up and transfer may be performed by using a magnetic suction-type robotic arm, facilitating an operation in assembling.

Optionally, a material of the metal housing is stainless steel, nickel silver, magnesium aluminum alloy, or the like.

In this embodiment, the metal housing has specific strength, to effectively prevent an electronic component on the camera body <NUM> from being damaged, to protect the electronic component.

In an embodiment provided in this application, a heat conductive agent is filled in a gap between the accommodation housing <NUM> and the camera body <NUM>.

A camera generates heat during operation, causing an internal temperature of the device to rise rapidly. To quickly transfer the heat, the heat conductive agent may be filled in the gap between the accommodation housing <NUM> and the camera body <NUM>, and the heat is transferred to the accommodation housing <NUM> in a heat conduction manner. Then heat reaching the accommodation housing <NUM> is emitted to the environment through the middle frame <NUM> or a rear cover. The heat conductive agent may effectively fill the gap between the accommodation housing <NUM> and the camera body <NUM>, reduce heat resistance, improve a capability of heat conduction from the camera body <NUM> to the accommodation housing <NUM>, and make heat conduction more smooth and fast.

Optionally, the heat conductive agent may be a liquid metal. Specifically, a metal material may be a gallium-based alloy, an indium-based alloy, or a bismuth-based alloy.

In the foregoing embodiment, the camera support <NUM> having the convex accommodation housing <NUM> is described in detail. In another embodiment, a structure of the camera support <NUM> is designed in another manner. Details are as follows.

<FIG> is a schematic diagram of an example of the camera support <NUM> according to an embodiment of this application. <FIG> is a sectional view of another example of the front camera assembling structure according to an embodiment of this application.

As shown in <FIG> and <FIG>, in an embodiment provided in this application, the camera support <NUM> includes a concave receiving groove <NUM>. A bottom groove wall of the receiving groove <NUM> is provided with an avoidance hole <NUM> for avoiding the lens <NUM>. The camera body <NUM> is fastened in the receiving groove <NUM>. After successively passing through the avoidance hole <NUM> and a hole channel <NUM>, the lens <NUM> of the camera body <NUM> extends into the camera hole <NUM> and is disposed in a centering manner. An outer side of a groove wall of the receiving groove <NUM> is fastened in an accommodation groove <NUM>.

In this embodiment, the camera support <NUM> is fastened to the middle frame <NUM>, to fasten the camera body <NUM> in the accommodation groove <NUM>. In this fastening manner, the camera support <NUM> is directly fastened, and direct contact with the camera body <NUM> may be prevented, preventing damage to the camera body <NUM> during fastening, and reducing an object loss during assembling.

In an embodiment provided in this application, a size of the outer side of the groove wall of the receiving groove <NUM> is smaller than a size of the accommodation groove <NUM>, to enable the camera support <NUM> to have an adjustment allowance relative to the middle frame <NUM>.

In this embodiment, because the size of the outer side of the groove wall of the receiving groove <NUM> is less than the size of the accommodation groove <NUM>, the receiving groove <NUM> may be displaced in a horizontal direction in the accommodation groove <NUM>, enabling the camera support <NUM> to have an adjustment allowance in the horizontal direction relative to the middle frame <NUM> when the lens <NUM> and the camera hole <NUM> are adjusted in a centering manner.

The outer side of the groove wall of the receiving groove <NUM> is fastened in the accommodation groove <NUM> in a plurality of manners, for example, the fastening may be implemented in a manner in which the camera support <NUM> is connected to the middle frame <NUM> by using fasteners <NUM>. As shown in <FIG>, in an embodiment provided in this application, two ends of the camera support <NUM> are provided with first installation holes <NUM>, the middle frame <NUM> is provided with second installation holes <NUM> corresponding to the first installation holes <NUM>, and the fasteners <NUM> are disposed in the first installation hole <NUM> and the second installation hole <NUM> to fasten the camera support <NUM> to the middle frame <NUM>. In this case, the outer side of the groove wall of the receiving groove <NUM> is fastened in the accommodation groove <NUM>.

Alternatively, the outer side of the groove wall of the receiving groove <NUM> is bonded and fastened in the accommodation groove <NUM> by an adhesive <NUM>. As shown in <FIG>, in an embodiment provided in this application, the adhesive <NUM> is filled between the outer side of the groove wall of the receiving groove <NUM> and a groove wall of the accommodation groove <NUM> to bond and fasten the receiving groove <NUM> and the accommodation groove <NUM>.

Alternatively, both bonding by using the adhesive <NUM> and connection by using the fasteners <NUM> may be used simultaneously.

Design of the fasteners <NUM> and the second installation holes <NUM> are similar to design of the fasteners <NUM> and the second installation holes <NUM> in the previous embodiment.

<FIG> is a schematic diagram of an example of the camera body <NUM> according to an embodiment of this application. <FIG> is a schematic diagram of another example of the camera support <NUM> according to an embodiment of this application.

As shown in <FIG>, <FIG>, and <FIG>, in an embodiment provided in this application, an error-proof mechanism <NUM> is provided on the camera support <NUM> and the camera body <NUM>.

When the camera support <NUM> and the camera body <NUM> are assembled, assembly efficiency and precision can be improved.

An embodiment of this application further provides an electronic device. The electronic device includes the foregoing assembling structure.

The electronic device may be a mobile phone shown in <FIG>. Different from an electronic device in the related technology, the front camera assembling structure provided in an embodiment of this application is disposed in a housing <NUM> of the mobile phone.

In addition, the electronic device may alternatively be any one of a notebook computer, a tablet computer, and an electronic watch.

Because the foregoing front camera assembling structure is used for the electronic device provided in this embodiment of this application, the lens black edge <NUM> of the front camera of the electronic device is smaller, the screen-to-body ratio is higher, and requirements for size precision and installation precision of parts are also relatively low, reducing overall difficulties in processing and assembling the electronic device and reducing manufacturing costs.
