Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] Camera modules are an important component of electronic devices. To improve shooting quality, multiple camera modules are typically used as rear-facing modules in related technologies. These multiple camera modules complement each other to enhance the overall shooting performance of the rear-facing module. These multiple camera modules can include wide-angle modules, etc. Compared to the main camera module with a standard focal length, the focal length of the wide-angle module is relatively smaller, which makes the thickness (i.e., the dimension in the optical axis direction) of the wide-angle module relatively smaller as well.

[0003] Given the above, to ensure a relatively large field of view for multiple camera modules and improve shooting performance, related technologies typically place a spacer or bracket below the wide-angle module to match the mounting height of the multiple camera modules. However, the spacer or bracket obstructs the installation of other electronic components on the circuit board corresponding to the wide-angle module, requiring a corresponding increase in the circuit board size. This encroaches on the space within the electronic device intended for the battery, negatively impacting the device's battery life. Summary of the Invention

[0004] The purpose of this application is to provide an electronic device that solves the problem in the related art where the size of the circuit board needs to be increased due to the obstruction of the pad or bracket, which in turn occupies the space in the electronic device to accommodate the battery, thus adversely affecting the battery life of the electronic device.

[0005] This application provides an electronic device including a circuit board, a first camera module, and a second camera module. Both the first and second camera modules are disposed on the same side of the circuit board, and the thickness of the first camera module is less than the thickness of the second camera module. A shielding component is provided on the circuit board, and the first camera module is disposed on the side of the shielding component away from the circuit board, so that the height difference between the end of the first camera module away from the circuit board and the end of the second camera module away from the circuit board is less than a preset threshold. An electronic component is disposed between the shielding assembly and the circuit board, and the shielding assembly surrounds the electronic component to prevent the electronic component from interfering with the first camera module.

[0006] This application discloses an electronic device in which a first camera module and a second camera module are both disposed on the same side of a circuit board, and the thickness of the first camera module is less than the thickness of the second camera module. The circuit board is provided with a shielding component, and the first camera module is disposed on the side of the shielding component away from the circuit board. This allows the shielding component to elevate the first camera module, ensuring that the height difference between the ends of the first and second camera modules away from the circuit board is less than a preset threshold. This achieves height matching between the first and second camera modules, thereby improving their shooting performance. Furthermore, in the electronic device disclosed in this application, electronic components can be disposed between the shielding component and the circuit board. This allows the area of ​​the circuit board facing the first camera module to still be effectively utilized, eliminating the need to increase the size of the circuit board. This results in a relatively larger area for accommodating the battery, increasing the battery size and volume, and improving the battery life of the electronic device. Additionally, in this application, the shielding component provides isolation and shielding for the electronic components by surrounding them, preventing interference from the electronic components with the first camera module and ensuring relatively high operational stability of the first camera module.

Detailed Implementation

[0009] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0010] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0011] like Figures 1-6 As shown in the figure, this application discloses an electronic device, which can be a mobile phone or a tablet computer, etc. In detail, the electronic device disclosed in this application includes a housing (not shown in the figure), a circuit board 100, a first camera module 400 and a second camera module (not shown in the figure). Of course, the electronic device may also include a display screen and a battery, etc., which will not be listed here.

[0012] The housing is the external structure of the electronic device, which is typically assembled with the display screen and forms an inner cavity. Components such as the circuit board 100 and the battery can be installed within this inner cavity. More specifically, the housing can be made of materials such as metal or plastic, and it is typically a rectangular sheet structure. Of course, the actual structure and dimensions of the housing can be flexibly selected according to specific circumstances, and this article does not impose any limitations on this.

[0013] As mentioned above, the display screen and the housing are assembled together. In an electronic device, the side where the display screen is located is the front side of the electronic device, and correspondingly, the side where the housing is located is the rear side of the electronic device. Therefore, in an electronic device, the housing can also be called the rear shell.

[0014] Furthermore, in this embodiment, the housing is provided with a lens hole that penetrates the housing along its thickness direction. The thickness direction of the housing is parallel to the thickness direction of the circuit board 100. The lens hole is an opening provided by the housing to avoid obstructing the first camera module 400 and the second camera module in the electronic device, allowing at least a portion of the first camera module 400 and the second camera module to extend out of the aforementioned inner cavity. This reduces the thickness of other parts of the electronic device besides the first camera module 400 and the second camera module, minimizing the thickness of most areas of the electronic device. Simultaneously, because the housing has the aforementioned lens hole, the dimensions of both the first camera module 400 and the second camera module in the thickness direction of the circuit board 100 can be appropriately increased, thereby correspondingly increasing parameters such as the focal length of the first camera module 400 and the second camera module, thus improving the shooting effect of the first camera module 400 and the second camera module.

[0015] As described above, in the related technology, both the first camera module 400 and the second camera module are mounted on the circuit board 100. Due to the difference in thickness between the first camera module 400 and the second camera module, a spacer or bracket needs to be placed under the one with the smaller thickness during assembly. This results in the inability to install other electronic components in the area of ​​the circuit board 100 corresponding to the spacer or bracket, thus requiring an additional increase in the size of the circuit board 100. This leads to the occupancy of the battery installation space in the electronic device, thereby adversely affecting the battery life of the electronic device.

[0016] To address the aforementioned issues, in this embodiment, the electronic device includes a shielding component 10. The first camera module 400 and the second camera module are both located on the same side of the circuit board 100; that is, in this application, both the first camera module 400 and the second camera module are rear-mounted modules. Furthermore, in this application, the thickness of the first camera module 400 is less than the thickness of the second camera module. Therefore, in this application, the focal length of the first camera module 400 can be less than the focal length of the second camera module. For example, the first camera module 400 may include a wide-angle camera, and the second camera module may include a telephoto camera or a standard focal length camera, etc.

[0017] Based on the above, the circuit board 100 is provided with the aforementioned shielding component 10. In this application, the first camera module 400 can be positioned on the side of the shielding component 10 away from the circuit board 100. In this case, the shielding component 10 can provide a support for the relatively thin first camera module 400, thereby matching the heights of the first camera module 400 and the second camera module. In other words, the height difference between the end of the first camera module 400 away from the circuit board 100 and the end of the second camera module away from the circuit board 100 is less than a preset threshold. In this embodiment, the preset threshold can be in the range of 0~0.3mm (inclusive).

[0018] By adopting the above technical solution, the distance between the first camera module 400 and the second camera module and the lens covering the rear camera module in the electronic device can be equal or substantially equal. This makes the field of view of the first camera module 400 and the second camera module relatively large, and can minimize the diameter of the exposed light-transmitting hole on the aforementioned lens, thereby improving the consistency of the rear camera module.

[0019] In the electronic device disclosed in this application embodiment, the shielding component 10 is generally a "bowl-shaped" or cover-shaped structure. This allows the side of the shielding component 10 facing away from the first camera module 400 to form a receiving space with the circuit board 100, thereby enabling electronic components to be installed in the aforementioned receiving space and achieving the purpose of utilizing the area of ​​the circuit board facing the shielding component 10 (i.e., the first camera module 400). Therefore, in this application embodiment, electronic components can be disposed between the shielding component 10 and the circuit board 100. In addition, in this application, the shielding component 10 can also surround the electronic components to prevent the electronic components from interfering with the first camera module 400.

[0020] More specifically, in this application, the shielding component 10 may include a shielding cover. The shielding cover is a dome-shaped structure. After electronic components such as inductors, capacitors, and chips, other than the first camera module 400, are normally installed on the circuit board 100 of the electronic device, the space utilization purpose of the corresponding area in the circuit board 100 can be achieved by further installing the shielding cover above the aforementioned electronic components. At the same time, the shielding cover also serves as the mounting base for the first camera module 400. On the one hand, it improves the effective utilization of the thickness space in the electronic device. On the other hand, it can also provide a boost to the first camera module 400, so that the height difference between the end of the first camera module 400 away from the display screen and the end of the second camera module away from the display screen is less than a preset threshold, thereby improving the overall shooting effect of the rear module in the electronic device. In addition, the shielding cover can also provide shielding for the first camera module 400 to prevent the operation of electronic components below the shielding cover from interfering with the normal operation of the first camera module 400.

[0021] In other words, in this application, the shielding cover is fixedly mounted on the circuit board 100, and the first camera module 400 can be mounted on the side of the shielding cover facing away from the circuit board 100. Simultaneously, the area of ​​the circuit board 100 facing the shielding cover can be used to mount electronic components other than the first camera module 400, such as inductors, capacitors, and chips. This allows the area of ​​the circuit board 100 opposite to the first camera module 400 to still be utilized normally. Furthermore, while keeping the number of electronic components constant or substantially constant, the size of the circuit board 100 can be appropriately reduced, thereby increasing the space in the electronic device for accommodating the battery. This allows the battery's size in the thickness direction perpendicular to the circuit board 100 to be correspondingly increased, thereby increasing the battery capacity without increasing the battery's thickness, enabling the electronic device to balance battery life and a slim design.

[0022] As described above, in the electronic device for which protection is claimed in this application, electronic components such as chips and inductors may be located beneath the shielding cover. These electronic components may generate low-frequency magnetic fields during the operation of the electronic device. These low-frequency magnetic fields can interfere with the imaging, focusing, and photosensing processes of the first camera module 400 mounted on the other side of the shielding cover, resulting in abnormalities such as stripes, noise, and color distortion in the image of the first camera module 400. Therefore, in this application, the shielding cover can be made of a material with relatively high magnetic permeability, and within the allowable space, the thickness of the shielding cover can be increased as much as possible to ensure that the shielding cover can absorb and shunt the low-frequency magnetic fields generated by the inductors and chips located beneath it. This suppresses or even eliminates the interference of the low-frequency magnetic field on the normal operation of the first camera module 400, thereby preventing electronic components from interfering with the first camera module 400.

[0023] This application discloses an electronic device in which a first camera module 400 and a second camera module are both disposed on the same side of a circuit board 100, and the thickness of the first camera module 400 is less than the thickness of the second camera module. The circuit board 100 is provided with a shielding component 10, and the first camera module 400 is disposed on the side of the shielding component 10 away from the circuit board 100. This allows the shielding component 10 to elevate the first camera module 400, thereby reducing the height difference between the ends of the first and second camera modules away from the circuit board to less than a preset threshold. This achieves height matching between the first and second camera modules, thereby improving their shooting performance. Furthermore, in the electronic device disclosed in this application, electronic components can also be disposed between the shielding component 10 and the circuit board 100. This allows the area of ​​the circuit board 100 facing the first camera module 400 to still be effectively utilized, eliminating the need to increase the size of the circuit board 100. This results in a relatively larger area for accommodating the battery, increasing the battery size and volume, and improving the battery life of the electronic device. In addition, in this application, the shielding component 10 can provide isolation and shielding for the electronic components by surrounding them, thereby preventing the electronic components from interfering with the first camera module 100 and ensuring that the first camera module 100 has relatively high working stability.

[0024] In the above embodiments, the shielding component 10 may include a shielding cover. The inventors further discovered that when adopting the above technical solution, in order to ensure the shielding and isolation effect, it is necessary to appropriately increase the bottom thickness of the shielding cover, which will greatly increase the processing and assembly difficulty of the shielding cover.

[0025] In detail, the shielding cover is positioned above the electronic components on the motherboard, giving it a bowl-like shape. Visually, the shielding cover includes a bottom and sides. The sides are flanged and connected to the edge of the bottom, extending towards one side of the bottom. During manufacturing, the shielding cover can be formed from a single sheet of metal, and the aforementioned sides can be formed through bending and other methods. When the thickness of the bottom of the shielding cover needs to be increased, the sides inevitably need to be enlarged as well. This increases the difficulty of bending the sides, and the increased thickness also results in a larger area occupied by the sides on the circuit board 100 when they are connected, making the connection between the sides and the circuit board 100 more difficult.

[0026] To address the aforementioned problems, the inventors further proposed that the shielding cover can be divided into two independent parts. This allows the total thickness of the portion of the shielding cover located above electronic components such as inductors and chips to remain relatively large, thus providing good isolation for the first camera module 400. Simultaneously, it also allows for a relatively smaller thickness on the side (and bottom) of the portion directly connected to the circuit board 100, reducing the processing and assembly difficulty of each part.

[0027] More specifically, regarding the above technical solutions, in the electronic device disclosed in the embodiments of this application, the shielding component 10 may include a separately formed first shielding member 210 and a second shielding member 310. The structure of the first shielding member 210 in this embodiment is similar to that of the shielding cover in the above embodiments; both are "bowl-shaped." The first shielding member 210 is also fixedly mounted on the circuit board 100 to cover the inductors, chips, and other electronic devices mounted on the circuit board 100 below it. Of course, in this application, both the first shielding member 210 and the second shielding member 310 are formed of materials with relatively high magnetic permeability.

[0028] Therefore, in the electronic device disclosed in this application embodiment, the first shield 210 can be fixedly mounted on the circuit board 100, and the area of ​​the circuit board 100 facing the first shield 210 can be used to install electronic components such as inductors and chips. Correspondingly, the first shield 210 surrounds the aforementioned electronic components. At the same time, in this embodiment, the second shield 310 is mounted on the side of the first shield 210 away from the circuit board 100. This makes the overall thickness of the second shield 310 and the first shield 210 relatively large, ensuring that the isolation effect of low-frequency magnetic fields generated by the operation of electronic components such as inductors and chips is still relatively good, thereby preventing low-frequency magnetic fields from interfering with the normal operation of the first camera module 400 located on the other side of the second shield 310.

[0029] Accordingly, such as Figure 1 and Figure 2 As shown, in this application, the first camera module 400 is installed on the side of the second shield 310 away from the first shield 210. Accordingly, in order to improve the shooting effect of the first camera module 400 and take into account the overall thickness of the electronic device, in this embodiment, a part of the first camera module 400 can extend through the lens hole to the side of the housing away from the circuit board 100.

[0030] The second shielding component 310 and the first shielding component 210 can be fixed to each other by welding or other means. Of course, in other embodiments of this application, other methods can also be used to make the second shielding component 310 and the first shielding component 210 form a stable fixed assembly relationship.

[0031] In order to ensure that the assembly accuracy between the first camera module 400 and the circuit board 100 is still relatively high when adopting the above technical solution, in a specific embodiment of this application, positioning marks can be provided on the circuit board 100, the first shield 210 and the second shield 310. Then, in the process of assembling electronic equipment, the first shield 210 can be installed based on the positioning marks on the circuit board 100, and the second shield 310 can be installed based on the positioning marks on the first shield 210. Similarly, the first camera module 400 can be installed based on the positioning marks on the second shield 310.

[0032] The first shielding member 210 and the circuit board 100 can be fixed to each other by welding to ensure a stable fixed connection. Meanwhile, to ensure a good positioning relationship between the second shielding member 310 and the first shielding member 210, in another embodiment of this application, such as... Figure 3 As shown, in the first direction, at least one claw 320 can be provided on each of the opposite sides of the second shielding member 310. Simultaneously, in the second direction, at least another claw 320 can be provided on each of the opposite sides of the second shielding member 310. Each claw 320 extends and bends along the thickness direction of the circuit board 100 towards the side where the first shielding member 210 is located. Thus, the second shielding member 310 can be engaged with the first shielding member 210 in both the first and second directions via the multiple claws 320. The first and second directions are perpendicular to each other and both perpendicular to the thickness direction. Specifically, the claws 320 and the second shielding member 310 can be connected to each other by welding or other methods. To reduce processing difficulty and improve the positioning accuracy of the claws 320, in another embodiment of this application, the multiple claws 320 and the second shielding member 310 can be integrally formed.

[0033] With the above technical solution, since the second shielding component 310 is provided with claws 320 on all four sides, during the assembly of the second shielding component 310, the second shielding component 310 can be directly stacked on top of the first shielding component 210 (i.e., on the side of the first shielding component 210 away from the circuit board 100). Under the combined action of multiple claws 320, the second shielding component 310 can automatically achieve the positioning process between itself and the first shielding component 210, thereby greatly reducing the assembly difficulty of the second shielding component 310 and ensuring high positioning accuracy between the second shielding component 310 and the first shielding component 210.

[0034] It should be noted that, in the process of adopting the above embodiments of this application, the spacing between corresponding pairs of the multiple claws 320 provided on the edge of the second shield 310 in the corresponding directions needs to be designed to ensure that the multiple claws 320 can provide a limiting effect for the second shield 310 in the first and second directions respectively. For example, taking two claws 320 respectively provided on the opposite two sides of the edge of the second shield 310 along the first direction as an example, the spacing between the two claws 320 needs to correspond to the size of the area in the first shield 210 corresponding to the two claws 320 in the first direction. Usually, the spacing between the two claws 320 can be equal to or slightly larger than the size of the corresponding area in the first shield 210, so as to ensure that the two claws 320 do not hinder the formation of the stacking relationship between the second shield 310 and the first shield 210 during the assembly of the second shield 310, and that the two claws 320 can also provide a limiting effect for the second shield 310 in the first direction. The solution in which the distance between the two claws 320 is equal to the size of the first shield 210 is a critical case.

[0035] Furthermore, in the above embodiments, each of the four edges of the second shielding member 310 may have only one claw 320. In this case, the four claws 320 are grouped in pairs and provide limiting functions for the second shielding member 310 in the first and second directions respectively, ensuring high positioning accuracy between the second shielding member 310 and the first shielding member 210. In other embodiments of this application, at least one edge of the second shielding member 310 may also have multiple claws 320, and the multiple claws 320 may be spaced apart, which can further improve the positioning effect of the claws 320 on the second shielding member 310.

[0036] Furthermore, when adopting the above-described embodiments of this application, a protrusion can be provided on the side of the claw 320 facing the first shield 210, and a groove or through hole can be provided at the corresponding position on the first shield 210. This allows the protrusion on the inner side of the claw 320 to be embedded into the groove or through hole of the first shield 210 after the claw 320 moves to the corresponding position. This enables the second shield 310 and the first shield 210 to be further mutually limited in the thickness direction of the circuit board 100, thereby enabling the second shield 310 and the first shield 210 to form a stable fixed assembly relationship.

[0037] As described above, positioning marks or similar devices can be used to provide positioning for the installation of the first camera module 400. In another embodiment of this application, a structure similar to the claw 320 described above can also be used to provide positioning for the first camera module 400.

[0038] Furthermore, in order to ensure that the first camera module 400 and the second shield 310 still have relatively good positioning accuracy and reduce the overall structural complexity of the second shield 310, in another embodiment of this application, the electrical connection structure between the first camera module 400 and the circuit board 100 can be combined with a claw 320 similar to the above-mentioned to jointly provide positioning for the first camera module 400.

[0039] In detail, in this embodiment, the circuit board 100 is provided with a first connector, and the first camera module 400 may include a module body 410, a flexible board 420, and a second connector 430. The module body 410 is electrically connected to the second connector 430 via the flexible board 420, and the second connector 430 is plugged into and electrically connected to the first connector to ensure an electrical connection between the module body 410 and the circuit board 100. Specifically, the first connector and the second connector 430 may be board-to-board (BTB) connectors.

[0040] Meanwhile, in this embodiment, in the first direction, the second shield 310 has a limiting flange 330 on the side edge away from the first connector, and the limiting flange 330 bends and extends along the thickness direction of the circuit board 100 towards the side away from the first shield 210. In the first direction, the limiting flange 330 can block one side of the module body 410. In detail, the limiting flange 330 protrudes from the surface of the second shield 310 away from the first shield 210, so that the limiting flange 330 can restrict the module body 410 from moving excessively away from the first connector in the first direction. Thus, under the combined action of the first connector and the limiting flange 330, the first camera module 400 and the second shield 310 can form a relatively good positioning relationship in the first direction.

[0041] Meanwhile, in this application, since the flexible plate 420 can only generate telescopic deformation in the first direction, and does not have the ability to telescopic deformation in the second direction perpendicular to the first direction, the first camera module 400, including the module body 410, the flexible plate 420 and the second connector 430, also has strong rigidity in the second direction. Based on this, by utilizing the positioning relationship between the second connector 430 and the first connector in the second direction, the first camera module 400 and the second shield 310 can also form a good positioning effect in the second direction.

[0042] In addition, in this embodiment, the distance between the limiting flange 330 and the first connector in the first direction can be greater than the maximum size of the first camera module 400 in the first direction. Thus, during the assembly of the first camera module 400, the flexible plate 420 is compressed in the first direction. Then, during the insertion and assembly of the second connector 430 and the first connector, the flexible plate 420 can push the module body 410 to move closer to the limiting flange 330 and abut against the limiting flange 330, thereby achieving the purpose of positioning the first camera module 400 and the second shield 310 in the first and second directions.

[0043] Of course, in this embodiment, the extension dimension of the limiting flange 330 in the second direction can be appropriately increased so that the module body 410 can move to abut against the limiting flange 330 under the extrusion of the flexible plate 420, so that the limiting flange 330 can provide a larger range of limiting effect for the module body 410, which is beneficial to improving the positioning accuracy of the module body 410 and the second shield 310 in the second direction.

[0044] Specifically, the limiting flange 330 can be a planar sheet structure, and the limiting flange 330 can be fixedly connected to the second shielding member 310 by welding. In order to reduce the processing difficulty and improve the positioning accuracy of the limiting flange 330, in another specific embodiment of this application, the limiting flange 330 and the second shielding member 310 can be formed by integral molding. In this embodiment, except for the area of ​​the limiting flange 330 connected to the second shielding member 310 which is a bent structure, the other parts of the limiting flange 330 can still be a planar sheet structure.

[0045] Of course, in other embodiments of this application, the end of the limiting flange 330 away from the second shield 310 can be further bent and extended to the side away from the second shield 310, thereby forming a more three-dimensional overall structure of the limiting flange 330, so as to provide a gripping position for gripping mechanisms such as robotic arms during the assembly process, thereby improving the assembly efficiency of the second shield 310.

[0046] Therefore, in this application, the second shielding member 310, the limiting flange 330, and each claw 320 are integrally formed. That is, in this embodiment, the same piece of metal material can be used as the base material, and an integral structure including the limiting flange 330, multiple claws 320, and the second shielding member 310 can be formed through bending and other processes, and the limiting flange 330 and multiple claws 320 are all connected to the corresponding edges of the second shielding member 310.

[0047] As described above, in the electronic device disclosed in this application, both the first shielding member 210 and the second shielding member 310 are formed of materials with relatively high magnetic permeability to improve their shielding effect against low-frequency magnetic fields. To further improve the shielding effect of the first shielding member 210 against electric fields, both the first shielding member 210 and the second shielding member 310 can be formed of materials with relatively high magnetic permeability and electrical conductivity. In a specific embodiment of this application, both the first shielding member 210 and the second shielding member 310 can be formed of a chromium-zirconium-copper alloy; that is, both the first shielding member 210 and the second shielding member 310 are chromium-zirconium-copper alloy structural components.

[0048] In the above embodiments, both the first shield 210 and the second shield 310 are made of metal. In this case, if the distance between the antenna of the electronic device and the first shield 210 and the second shield 310 is small, it will also interfere with the normal operation of the first camera module 400. Therefore, in a specific embodiment of this application, the first shield 210 can be grounded and the second shield 310 can be electrically connected to the first shield 210, so that both the first shield 210 and the second shield 310 are grounded to prevent the antenna from interfering with the normal operation of the first camera module 400 installed on one side of the second shield 310. Specifically, in one embodiment of this application, the second shield 310 and the first shield 210 can be electrically connected by making them contact each other. Alternatively, as described above, the edge of the second shield 310 can be provided with claws 320, and the claws 320 extend towards the first shield 210 so that the second shield 310 is mutually limited with the first shield 210 by multiple claws 320. This makes it possible for the claws 320 and the first shield 210 to also form a good contact relationship, thereby ensuring that the second shield 310 can be electrically connected with the first shield 210.

[0049] As described above, the area on the circuit board 100 facing the first shield 210 can be used to mount electronic components such as inductors and chips. Considering that electronic devices may be bumped or knocked during use, and to prevent the electronic components below the first shield 210 from connection failure due to violent shaking when the electronic device is dropped, etc. Figure 5 As shown in the embodiment of this application, the first shield 210 is provided with an injection hole 211. After the first shield 210 and the circuit board 100 are fixedly assembled, the filling glue for stress relief can be injected into the cavity formed by the first shield 210 and the circuit board 100 through the injection hole 211, so as to improve the stability of the assembly relationship between the electronic device below the first shield 210 and the circuit board 100.

[0050] When the above technical solution is adopted, since the first shielding member 210 is provided with a glue injection hole 211, electromagnetic interference generated by electronic devices below the first shielding member 210 can leak through the glue injection hole 211. Therefore, in this embodiment of the application, the electronic device further includes a conductive shielding layer 510, wherein, as shown in the example... Figures 4-6 As shown, the conductive shielding layer 510 is attached to the side of the first shielding member 210 facing the second shielding member 310, and the conductive shielding layer 510 seals the glue injection hole 211, so that the first shielding member 210 and the conductive shielding layer 510 can still provide a relatively comprehensive isolation effect for the electronic devices below.

[0051] Specifically, the conductive cover layer 510 may include copper foil or conductive cloth, and the shape and size of the conductive cover layer 510 may correspond to the glue injection hole 211, and the conductive cover layer 510 may fully cover the glue injection hole 211.

[0052] As described above, a portion of the first camera module 400 extends through the lens hole of the housing to the side of the housing opposite to the circuit board 100. That is, in this application, the first camera module 400 can be referred to as a rear camera. Meanwhile, to improve user experience, electronic devices typically also include a front-facing camera. In this application, the aforementioned camera may include a third camera module 600, which is positioned opposite to the first camera module 400. Furthermore, to prevent interference signals from affecting the normal operation of the front-facing camera, the third camera module 600 can be grounded via a conductive device such as a wire to conduct interference signals to ground.

[0053] Based on the above, in the embodiment where the first shield 210 is grounded and a conductive cover layer 510 for covering and sealing the glue injection hole 211 is attached to the first shield 210, the third camera module 600 can be directly electrically connected to the first shield 210 through the conductive cover layer 510 by appropriately extending the length of the conductive cover layer 510, thereby achieving the grounding purpose of the third camera module 600. This can achieve the effect of using one thing for two purposes, saving materials and assembly processes, and thus reducing the overall cost of electronic equipment.

[0054] In detail, in the embodiments of this application, the electronic device includes a third camera module 600. The light entrance hole of the third camera module 600 is disposed opposite to the lens hole. That is, the viewfinder side of the third camera module 600 is opposite to that of the first camera module 400. At the same time, the third camera module 600 is electrically connected to the circuit board 100, and the third camera module 600 is also grounded through a conductive cover layer 510.

[0055] As described above, the second shielding member 310 is disposed on the side of the first shielding member 210 away from the circuit board 100, and the two can also form an electrical connection. Based on this, in a specific embodiment of this application, the electronic device can include conductive double-sided adhesive 520, wherein the second shielding member 310 is bonded to and electrically connected to the first shielding member 210 through the conductive double-sided adhesive 520, which can ensure that the second shielding member 310 and the first shielding member 210 can be electrically connected to each other, while also forming a limiting relationship in the thickness direction of the circuit board 100.

[0056] Meanwhile, in the above embodiments of this application, a conductive cover layer 510 is provided on the side of the first shielding member 210 facing the second shielding member 310. Based on this, in order to minimize the increase in the thickness of the area where the first camera module 400 is located in the electronic device, in a specific embodiment of this application, the conductive double-sided adhesive 520 and the conductive cover layer 510 can be staggered. Alternatively, in this embodiment, in a plane perpendicular to the thickness direction of the circuit board 100, the projection of the conductive double-sided adhesive 520 is located outside the projection of the conductive cover layer 510, so that the conductive double-sided adhesive 520 and the conductive cover layer 510 share the same thickness space. This ensures a relatively good assembly and electrical connection between the second shielding member 310 and the first shielding member 210 while minimizing the excessive thickness of the area where the first camera module 400 is located in the electronic device. More specifically, the thicknesses of the conductive double-sided adhesive 520 and the conductive cover layer 510 can be made approximately equal.

[0057] Considering the limited adhesive effect of conductive double-sided adhesive 520, in order to improve the stability of the fixed assembly relationship between the second shielding component 310 and the first shielding component 210, in a specific embodiment of this application, the electronic device may also include insulating double-sided adhesive 530. The insulating double-sided adhesive 530 is a double-sided adhesive used only for providing adhesion and does not have conductive properties; therefore, its adhesive strength is stronger. In this case, the second shielding component 310 is bonded and fixed to the first shielding component 210 by the insulating double-sided adhesive 530, thereby ensuring a more reliable fixed connection between the second shielding component 310 and the first shielding component 210, and making the processing difficulty of the second shielding component 310 (and the aforementioned claw 320) and the first shielding component 210 relatively lower.

[0058] Of course, in order to minimize the increase in the thickness of the area where the first camera module 400 is located in the electronic device, in this embodiment, the projection of the insulating double-sided adhesive 530 is located outside the projections of the conductive double-sided adhesive 520 and the conductive cover layer 510 in a plane perpendicular to the thickness direction of the circuit board 100. Intuitively speaking, in this embodiment, as... Figure 6As shown, any two of the insulating double-sided adhesive 530, conductive double-sided adhesive 520, and conductive shielding layer 510 are staggered to each other so that the three can share the same thickness space. This further improves the assembly stability between the second shielding component 310 and the first shielding component 210, while minimizing the thickness of the area where the first camera module 400 is located in the electronic device.

[0059] Of course, during the design and manufacturing process of electronic devices, the shapes of the insulating double-sided adhesive 530, conductive double-sided adhesive 520, and conductive masking layer 510 can be flexibly determined according to actual needs to achieve their respective functions. This article does not impose any restrictions on this. In addition, in the thickness direction of the circuit board 100, the dimensions of the insulating double-sided adhesive 530, conductive double-sided adhesive 520, and conductive masking layer 510 can be made as similar as possible.

[0060] In addition, in order to improve the uniformity of the bonding and fixing relationship between any position of the second shielding member 310 and the first shielding member 210, in a specific embodiment of this application, at least a portion of the insulating double-sided adhesive 530 can be sandwiched between the conductive double-sided adhesive 520 and the conductive covering layer 510 along the first direction or the second direction. This allows the middle part of the second shielding member 310 to form a reliable bonding and fixing relationship with the first shielding member 210 through the insulating double-sided adhesive 530, ensuring that the bonding and fixing relationship between different areas of the second shielding member 310 and the first shielding member 210 is relatively good.

[0061] In the electronic device disclosed in this application embodiment, the area where the circuit board 100 and the first camera module 400 are located may also need to be laid with cables, including coaxial cables. Based on this, in order to improve the reliability of cable laying, in this application embodiment, a limiting arm 220 can be provided on one side edge of the first shield 210. Of course, in the process of setting the limiting arm 220, the position of the limiting arm 220 needs to be designed according to the cable laying path. At the same time, in this embodiment, a gap can be formed between the limiting arm 220 and the first shield 210. The gap is used to accommodate the cable, so that the cable can be limited between the limiting arm 220 and the first shield 210 (and the second shield 310 and the first camera module 400 installed thereon), ensuring that the coaxial cable laying state is relatively stable and reducing the installation difficulty of the coaxial cable.

[0062] In addition, in this embodiment, the coaxial cable can be extended between the first shield 210 and the first connector by bending after passing through the above-mentioned gap, so that the coaxial cable can also be sandwiched between the first camera module 400 and the circuit board 100 in the thickness direction of the circuit board 100, so as to further improve the layout stability of the coaxial cable.
