Technical Field

[0001] The embodiments of the present application relate to the technical field of terminal devices, and in particular to a camera module and an electronic device. Background Art

[0002] With the continuous development of electronic technology, various types of terminal devices with different performances have appeared in the market, and users have more and more choices for terminal devices. The shooting function has become an indispensable function for these terminal devices, and it is also an important factor that users will consider when choosing to buy terminal devices. In order to obtain good shooting effects, it is necessary to match a camera module with good performance.

[0003] The shooting performance of the camera module has an important impact on the performance improvement of electronic devices. Since the space left for the camera module in the electronic device is limited, it is necessary to ensure the structural strength of the camera module while occupying the limited space. The structural strength of the camera module will affect whether the circuit board in the camera module will break easily. Therefore, how to ensure the structural strength of the camera module has become an important issue. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a camera module and an electronic device, which can ensure the structural strength of the camera module.

[0005] To solve the above technical problems, an embodiment of the present application provides a camera module. The camera module includes a circuit board, a lens assembly, a first shielding cover, a second shielding cover and a connector. The circuit board is provided with a lens area, and component areas distributed on both sides of the lens area along a preset direction. The lens assembly is provided in the lens area. The first shielding cover is provided on the component area on one side of the lens area. The second shielding cover is provided on the component area on the other side of the lens area. The connector is provided on the circuit board around the lens assembly and connects the first shielding cover to the second shielding cover.

[0006] An embodiment of the present application further provides an electronic device, which includes a housing, and the above-mentioned camera module is arranged in the housing.

[0007] The camera module and electronic device provided by the embodiments of the present application connect the first shielding member and the second shielding member located on both sides of the lens assembly by arranging a connector around the lens assembly on the circuit board, thereby reinforcing the area between the first shielding member and the second shielding member, so that the force on the circuit board is dispersed on the mating surface of the whole formed by the first shielding member and the second shielding member and the circuit board, thereby ensuring the structural strength of the camera module.

[0008] In some embodiments, there are multiple connectors, and the multiple connectors are symmetrically arranged about a preset direction. In this way, the first shielding member and the second shielding member can be connected from different positions through the multiple connectors, which can effectively enhance the connection strength between the first shielding member and the second shielding member.

[0009] In some embodiments, each connector includes a first portion, a second portion, and a third portion connecting the first portion and the second portion, the first portion is connected to the first shielding cover, the second portion is connected to the second shielding cover, and the third portion is disposed adjacent to the lens assembly. In this way, the connector can be connected to the shielding member through the first portion and the second portion, and span the lens assembly installation area through the third portion.

[0010] In some embodiments, the first part and the second part of each connecting member are bent from the edges of the third part away from each other to the same side of the third part. In this way, by bending the first part and the second part, the connection between the connecting member and the two shielding members can be easily achieved, and the position difference between the shielding member and the installation area where the lens assembly is located can be adapted.

[0011] In some embodiments, the connecting member and the first shielding cover are made of the same material, so that the connecting member can also play a shielding role and is conducive to improving the connection strength when the connecting member and the shielding cover are connected.

[0012] In some embodiments, each component area is provided with a welding area, the first shielding cover is welded to the welding area of ​​the component area located on one side of the lens assembly, and the second shielding cover is welded to the welding area of ​​the component area located on the other side of the lens assembly. In this way, the two shielding covers can be mounted on the circuit board by welding, thereby ensuring the connection strength of the two shielding covers after being mounted on the circuit board.

[0013] In some embodiments, each component area is provided with a plurality of welding areas, each welding area extends along a preset direction, and the plurality of welding areas of the same component area are arranged in parallel on the circuit board. In this way, the connection between the shielding cover and the circuit board can be achieved from different positions through the plurality of welding areas, which is conducive to enhancing the connection strength between the shielding cover and the circuit board.

[0014] In some embodiments, one end of the welding area extends toward the lens area and is disposed adjacent to the lens area. In this way, the length of the welding area can be increased, and the length of the weld between the shielding cover and the circuit board bracket can be increased, thereby improving the connection strength.

[0015] In some embodiments, reinforcing glue is filled between the first shielding cover and the lens assembly, and between the second shielding cover and the lens assembly. In this way, the reinforcing glue can be used to structurally reinforce the spacing area between the first shielding cover and the lens assembly, and the spacing area between the second shielding cover and the lens assembly.

[0021] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, each embodiment of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in each embodiment of the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not constitute any limitation, and the various embodiments can be combined with each other and referenced to each other without contradiction.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0023] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0024] With the development of the times, electronic devices such as laptops, tablets and all-in-one computers have gradually become an indispensable part of people's lives. Users' demand for electronic devices is also increasing, and their attention to the shooting performance of camera modules is also increasing. The shooting effect of the camera module affects the user's choice of electronic devices. In the increasingly miniaturized electronic devices, the space left for the camera module is becoming more and more limited. This also makes the structural strength of the camera module easily affected by the thin and light design of the components, and the circuit board in the camera module is easily broken due to external forces.

[0025] For example, in the process of repairing a laptop computer, it is inevitable to disassemble the camera. However, when disassembling the camera, it is easy to damage the camera module of good quality, and the loss rate of the disassembled camera module is close to 100%. The circuit boards in the camera module are basically long strips with narrow edges. When disassembling, tweezers are basically used to gently lift the PCB (Printed Circuit Board) board at the camera connector until the camera module is disassembled. However, during disassembly, the PCB board is subject to external forces at the position between the shielding cover and the lens bracket, and it is easy to deform. When the force applied to the PCB board reaches the limit, the PCB board will break at this point.

[0026] In order to ensure the structural strength of the camera module and prevent the circuit board in the camera module from being easily broken, some embodiments of the present application provide a camera module. The camera module connects the shielding covers on both sides of the lens bracket to form a whole through a connector, thereby improving the structural strength of the camera module and dispersing the force on the PCB board on the force-bearing surface. This prevents some parts of the PCB board from being easily deformed due to concentrated force, reduces the probability of the PCB board being broken due to force, and improves the reuse rate of the camera module.

[0027] Combine the following Figures 1 to 3 The camera module provided in some embodiments of the present application is described.

[0028] like Figures 1 to 3As shown, the camera module provided by some embodiments of the present application includes a circuit board 11, a lens assembly 12, a first shielding cover 13, a second shielding cover 14 and a connector 15. The circuit board 11 is provided with a lens area 111, and component areas 112 distributed on both sides of the lens area 111 along a preset direction. The lens assembly 12 is provided in the lens area 111. The first shielding cover 13 is provided on the component area 112 located on one side of the lens area 111. The second shielding cover 14 is provided on the component area 112 located on the other side of the lens area 111. The connector 15 is provided on the circuit board 11 around the lens assembly 12, and connects the first shielding cover 13 and the second shielding cover 14 together.

[0029] The circuit board 11 is the installation base for other components, and is also the carrier for electronic components to achieve electrical connection. Different components are installed in different areas on the circuit board 11, and the circuits on the circuit board 11 form a whole to achieve specific functions, such as shooting, signal transmission, or fill light of the camera module. The lens area 111 of the circuit board 11 provides an installation area for the installation of the lens assembly 12, and the component area 112 of the circuit board 11 provides an installation area for the installation of other electronic components. The component area 112 is located on both sides of the lens area 111 along a preset direction, and the preset direction can be the length direction of the circuit board 11.

[0030] The lens assembly 12 is a part of the camera module used for shooting. The lens assembly 12 may include a lens holder 121 and a lens 122. The lens holder 121 may be used to mount the lens 122, which may converge light and form an image of the scene on a CMOS (Complementary Metal Oxide Semiconductor) / CCD (Charge-Coupled Device) image sensor. In order to make the image clear and reduce aberration, the lens 122 may be a combination of multiple lenses, and the focal length required for the lens 122 to shoot may be adjusted as needed.

[0031] The first shielding cover 13 and the second shielding cover 14 are arranged on different component areas 112, and the electronic components installed on different component areas 112 can be covered inside. In order to shield the influence of external electromagnetic waves and avoid radiating electromagnetic waves to the outside world, the electronic components on the component area 112 can be protected. At the same time, after the first shielding cover 13 and the second shielding cover 14 are installed on the circuit board 11, the circuit board 11 can be reinforced. The first shielding cover 13 and the second shielding cover 14 can be metal covers made of metal shielding materials, or other covers with shielding functions. The first shielding cover 13 and the second shielding cover 14 can be connected to the circuit board 11 by welding to ensure the bonding strength.

[0032] The connecting member 15 is arranged around the lens assembly 12 to avoid affecting the shooting of the lens assembly 12. The connecting member 15 can be a continuously arranged component surrounding the periphery of the lens assembly 12, or a spaced component surrounding the periphery of the lens assembly 12. The connecting member 15 can connect the first shielding member and the second shielding member located on both sides of the lens assembly 12 together, so that the originally independent first shielding member and the second shielding member form a whole. Then, the area between the first shielding member and the second shielding member is reinforced.

[0033] It should be noted that an assembly safety space, i.e., a spacing area, is usually reserved between the first shielding cover 13 and the lens assembly 12, and between the second shielding cover 14 and the lens assembly 12. This makes it easy for the circuit board 11 to break at the position between the first shielding cover 13 and the lens assembly 12, and at the position between the second shielding cover 14 and the lens assembly 12 due to external forces.

[0034] Therefore, in the camera module provided by some embodiments of the present application, a connector 15 is provided on the circuit board 11 around the lens assembly 12 to connect the first shielding member and the second shielding member located on both sides of the lens assembly 12. Thus, the area between the first shielding member and the second shielding member is reinforced, so that the force on the circuit board 11 is dispersed on the mating surface of the whole formed by the first shielding member and the second shielding member and the circuit board 11, thereby ensuring the structural strength of the camera module.

[0035] In some embodiments, there may be multiple connecting members 15, and the multiple connecting members 15 are symmetrically arranged about a preset direction.

[0036] A plurality of connectors 15 may be distributed on both sides of the lens assembly 12, and the first shielding member and the second shielding member are connected together from both sides of the lens assembly 12. In addition, a plurality of connectors 15 may be symmetrically arranged on both sides of the lens assembly 12, so that the force on the regions on both sides of the lens assembly 12 on the circuit board 11 is relatively uniform. The number of connectors 15 may be two, four or six. As shown in the figure, there are two connectors 15. The two connectors 15 in the figure are located on different sides of the lens assembly 12, and each connector 15 is simultaneously connected to the first shielding member and the second shielding member, so that the first shielding member and the second shielding member are connected to form a whole.

[0037] In addition, each connecting member 15 may include a first part 151, a second part 152, and a third part 153 connecting the first part 151 and the second part 152, the first part 151 is connected to the first shielding cover 13, the second part 152 is connected to the second shielding cover 14, and the third part 153 is arranged adjacent to the lens assembly 12.

[0038] The first portion 151 and the second portion 152 are portions for connecting the connector 15 to different shielding members, and the third portion 153 is a portion with a larger area of ​​the connector 15. In addition, the third portion 153 of the connector 15 located on different sides of the lens assembly 12 stands upright on the circuit board 11, and after cooperating with the first shielding member and the second shielding member, the lens assembly 12 is covered therein.

[0039] like Figure 2 As shown, the first portion 151 and the second portion 152 of each connecting member 15 can be bent from edges of the third portion 153 that are away from each other toward the same side of the third portion 153 .

[0040] The first part 151 and the second part 152 are bent toward the same side of the third part 153, so that the first part 151 is opposite to the second part 152, and cooperates with the third part 153 to form a semi-enclosed structure. By bending the first part 151 and the second part 152, it is easy to achieve the connection between the connecting member 15 and the first shielding member and the second shielding member. At the same time, it is easy to adapt to the difference in the installation area occupied by the lens assembly 12 and the two shielding members in the vertical direction of the preset direction.

[0041] In some embodiments, the connecting member 15 and the first shielding cover 13 may be made of the same material.

[0042] That is to say, the connector 15 can be made of shielding material, thereby playing a shielding role together with the first shielding member and the second shielding member. At the same time, the connector 15 and the first shielding cover 13 are made of the same material, which can facilitate the connection between the two and ensure the connection strength between the two.

[0043] In some embodiments, each component area 112 is provided with a welding area 113, the first shielding cover 13 is welded on the welding area 113 of the component area 112 located on one side of the lens assembly 12, and the second shielding cover 14 is welded on the welding area 113 of the component area 112 located on the other side of the lens assembly 12.

[0044] That is to say, the first shielding cover 13 and the second shielding cover 14 can be connected to the circuit board 11 in the form of welding. The welding area 113 on the component area 112 can facilitate welding. During the welding process, the bottom surface of the first shielding member and the bottom surface of the second shielding member, that is, the side of the two shielding members connected to the circuit board 11, can be placed on the welding areas 113 of different component areas 112, and the welding process is performed by solder. Then, the first shielding cover 13 and the second shielding cover 14 are firmly mounted on the circuit board 11.

[0045] In addition, each component area 112 is provided with a plurality of welding regions 113 , each welding region 113 extends along a preset direction, and the plurality of welding regions 113 of the same component area 112 are arranged in parallel on the circuit board 11 .

[0046] The multiple welding areas 113 of the same component area 112 are arranged in parallel, corresponding to the parallel side walls of the shielding cover, and the welding areas 113 extending along the preset direction cover the bottom surfaces of the longer side walls of the two shielding covers. By arranging multiple welding areas 113 in the component area 112, it is ensured that a weld of sufficient length is formed between the first shielding cover 13 and the second shielding cover 14 and the circuit board 11 during installation, thereby ensuring the connection strength when the first shielding cover 13 and the second shielding cover 14 are connected to the circuit board 11.

[0047] In some embodiments, one end of the welding region 113 may extend toward the lens region 111 and be disposed adjacent to the lens region 111 .

[0048] The length of the welding area 113 can be increased by extending one end of the welding area 113 toward the lens area 111 until it is adjacent to the lens area 111. The length of the welding area 113 is sufficient to meet the strength requirement when the shielding cover is connected to the circuit board 11.

[0049] It should be noted that in Figure 4 In the case shown, the pad area is small, and the connection strength between the shielding cover and the circuit board 11 is limited. The circuit board 11 is easily broken due to the tilting of the camera connector end. When prying, the shielding cover is easily squeezed and deviated toward the lens bracket 121, causing the circuit board 11 to exceed the bearing range. By increasing the pad area, the adhesion between the shielding cover and the circuit board 11 can be increased, so that the shielding cover close to both sides of the lens bracket 121 will not be offset with the tilting of the circuit board 11, reducing the probability of the circuit board 11 breaking due to the disassembly of the camera module, thereby improving the reuse rate of the camera module.

[0050] In some embodiments, a reinforcing adhesive 16 may be filled between the first shielding cover 13 and the lens assembly 12 , and between the second shielding cover 14 and the lens assembly 12 .

[0051] Filling the reinforcing glue 16 in the gap area between the first shielding cover 13 and the lens assembly 12, and in the gap area between the second shielding cover 14 and the lens assembly 12 can reinforce the strength of the corresponding position of the circuit board 11 where there is a gap between the lens assembly 12 and the shielding cover, thereby reinforcing the strength of the camera module.

[0052] In addition, filling the reinforcing glue 16 between the shielding cover and the lens assembly 12 can effectively buffer the stress on the circuit board 11 during the disassembly process. The probability of the circuit board 11 being broken due to the disassembly of the camera module is reduced, thereby improving the reuse rate of the camera module. In actual situations, the maximum height of the reinforcing glue 16 may not exceed the height of the shielding cover, and the length of the reinforcing glue 16 is based on not overflowing to form excess parts, and the glue thickness can be above 0.8 mm (millimeter).

[0053] Some embodiments of the present application further provide an electronic device, which includes a housing, and the above-mentioned camera module is disposed in the housing.

[0054] The electronic device may be a laptop computer, a tablet computer, an all-in-one computer, etc. By adopting the above-mentioned camera module, the structure is strengthened to solve the problem that the circuit board in the camera module is easily broken due to external force.

[0055] The camera module in the electronic device can improve the structural strength of the camera module by connecting the shielding covers on both sides of the lens assembly to form a whole. In the process of disassembling the camera module, the stress on the circuit board in the camera module can be relieved and the stress can be dispersed to the mating surface. The probability of the circuit board breaking due to external force is reduced, and the reuse rate of the camera module is improved.

[0056] In addition, by increasing the welding area of ​​the shielding cover of the camera module, the shielding cover not only protects the internal components of the shielding cover, but also increases the adhesion between the shielding cover and the circuit board, thereby reducing the probability of the circuit board breaking and improving the reuse rate of the camera module after disassembly.

[0057] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present application, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present application.
