[0020] Please refer to Figure 1 , Figure 1 The structure diagram of the camera module provided by the embodiment of the application is shown in the figure. Figure 1 As shown in the figure, the camera module comprises:

[0022] The support spring 20 comprises a support part 21 and an elastic part 22, the support part 21 is located at the bottom of the camera body 10 and connected with the flexible circuit board 30, and the elastic part 22 and the flexible circuit board 30 are respectively located at opposite sides of the camera body 10.

[0023] As shown in Figure 1 The camera module comprises a camera body 10, a support spring 20 and a flexible circuit board 30, wherein the support spring 20 comprises a support part 21 and an elastic part 22, the support part 21 is a bottom surface for mounting the camera body 10, specifically, the camera body 10 is fixed on the upper surface of the support part 21; the elastic part 22 can be located on one side of the support part 21 and on one side of the camera body 10, for pre-positioning the camera body 10 to prevent the camera body from deviating too much from the center position; the flexible circuit board 30 is located on the other side of the camera body 10 and connected with the other side of the support part 21, and the camera body 10 is also electrically connected with the flexible circuit board 30, so that when the camera module is installed into an electronic device, the camera body 10 can be electrically connected with the mainboard in the electronic device through the flexible circuit board 30, realizing data communication between the camera body 10 and the mainboard.

[0024] According to some embodiments of the present application, the elastic part 22 and the flexible circuit board 30 are both located on the circumferential side of the camera body 10. In this way, one side of the camera body 10 can be blocked by the elastic part 22, so that the camera body 10 can be preliminarily positioned by the elastic part 22 to prevent the camera body 10 from moving outward, and the other side of the camera body 10 is electrically connected with the flexible circuit board 30.

[0025] According to some embodiments of the present application, the elastic part 22 is a curled structure, and the elastic part 22 abuts against one side of the camera body 10.

[0026] As shown in Figure 1 The elastic part 22 is a curled structure curled upward, so as to form a curled elastic part, and the curled structure of the elastic part 22 abuts against one side of the camera body 10, so as to well block the camera body 10 from moving outward, realizing the positioning function of the camera body 10.

[0027] According to some embodiments of the present application, the elastic part 22 comprises a first curled part 221, a second curled part 222 and a third curled part 223, the first curled part 221 and the third curled part 223 are respectively located at opposite ends of the second curled part 222, the width of the second curled part 222 is greater than the width of the first curled part 221 and greater than the width of the third curled part 223, and the second curled part 222 abuts against one side of the camera body 10.

The curling part at both ends is relatively narrow in width, and the curling part in the middle is relatively wide in width. In this way, when the camera body 10 is installed on the support part 21 and in contact with the elastic part 22, the second curling part 222 in the middle can abut against the camera body 10, and both ends are left with a certain gap for connection with the mainboard support in the electronic device, and the mainboard support is clamped thereon through the limiting bone position, thereby achieving more stable positioning of the camera body 10.

[0030] As shown in the drawings, Figure 1 As shown, the flexible circuit board 30 comprises a first circuit board 31 and an electronic connector 32, wherein the first circuit board 31 is also the FPC of the camera body 10, and is used for connection between the camera body 10 and the electronic connector 32, and the electronic connector 32 is also the BTB on the FPC of the camera body 10. The first side of the first circuit board 31 is connected to the camera body 10, and the second side is connected to the electronic connector 32. Specifically, the electronic connector 32 can be welded on the surface of the second side of the first circuit board 31, and the first side and the second side are opposite sides. Exemplarily, the BTB can be soldered on the FPC of the camera body 10. In this way, the camera body 10 can be directly installed on the mainboard of the electronic device through the BTB on the camera FPC.

[0031] According to the camera module in the embodiments of the present application, the camera module comprises a camera body, a support spring and a flexible circuit board. The support spring comprises a support part and an elastic part, the support part is located at the bottom of the camera body and connected to the flexible circuit board, and the elastic part and the flexible circuit board are located at opposite sides of the camera body. In this way, the elastic part of the support spring is used for pre-positioning the camera body, which can preliminarily ensure that the camera body is not easy to deviate from the center position and reduce the damage of the camera.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 , Figure 2 and Figure 3 are structural schematic diagrams of electronic devices provided by the embodiments of the present application and installed with the aforementioned camera module. As shown in Figure 1 , Figure 2 and Figure 3As shown, the electronic device comprises a circuit board assembly and the camera module described in the foregoing embodiments, the circuit board assembly comprises a main board 41 and a main board support 42, the camera module is arranged on the circuit board assembly, and the connector on the flexible circuit board 30 is buckled with the connector on the main board 41.

[0033] The main board 41 is used for supporting and connecting the camera body 10 through an electronic connector such as a board-to-board (BTB) connector, specifically, the connector on the flexible circuit board 30 is buckled with the connector such as a BTB on the main board 41, so that the middle part of the flexible circuit board 30 can be bent under stress. The main board 41 is positioned with the middle frame or the main board upper cover of the electronic device in a manner of positioning holes and positioning columns.

[0034] The main board support 42 is used for limiting the camera body 10 to prevent eccentricity, and the main board support 42 is positioned with the middle frame or the main board upper cover of the electronic device in a manner of positioning holes and positioning columns.

[0035] The electronic device provided in the embodiment can realize each of the camera module embodiments described above and achieve the same technical effects, and thus details are not repeated here.

[0036] According to some embodiments of the utility model, the supporting part 21 of the supporting spring 20 is fixedly installed on the main board 41.

[0037] One side of the main board support 42 is provided with a limiting bone site 421, the shape of the limiting bone site 421 is matched with the shape of the elastic part 22 of the supporting spring 20, the main board support 42 is installed on the main board 41 at a position corresponding to the camera body 10, and the limiting bone site 421 is clamped between the elastic part 22 and the camera body 10.

[0038] As shown in the figure, Figure 1 The main board support 42 is provided with a limiting bone site 421 on the side corresponding to the elastic part 22, which is used for pulling the elastic part 22 and limiting the camera body 10, the shape of the limiting bone site 421 is matched with the shape of the elastic part 22, so that when the main board support 42 is installed on the main board 41 at a position corresponding to the camera body 10, the limiting bone site 421 is clamped between the elastic part 22 and the camera body 10, realizing secondary positioning of the camera body 10, and making the camera body 10 firmly positioned at the current position and not moving.

[0039] According to some embodiments of the utility model, the width of the limiting bone site 421 at both ends is greater than the width of the middle part of the limiting bone site 421.

[0040] Correspondingly, as shown in the figure, Figure 1As shown, when the elastic part 22 includes a first curled part 221, a second curled part 222, and a third curled part 223, and the width of the second curled part 222 located in the middle is greater than the width of the first curled part 221 and the third curled part 223 located at both ends, the limiting bone position 421 can be adapted to the curled structure design of the elastic part 22 and is also designed as three parts. The width of the two ends of the limiting bone position 421 is wider and matches the size of the curled parts at both ends of the elastic part 22. The width of the middle part of the limiting bone position 421 is narrower and matches the size of the curled part in the middle of the elastic part 22. In this way, the limiting bone position 421 can be precisely positioned between the elastic part 22 and the camera body 10, so as to achieve a more stable positioning of the camera body 10.

[0041] According to some embodiments of the present invention, the elastic part 22 includes a first curled part 221, a second curled part 222 and a third curled part 223. The first curled part 221 and the third curled part 223 are respectively located at opposite ends of the second curled part 222. The lower part of the two ends of the limiting bone position 421 is a groove structure 422, in which the first curled part 221 and the third curled part 223 are accommodated.

[0042] like Figure 2 As shown, the lower ends of the limiting bone position 421 are groove structures 422, and the width of the groove structure 422 is adapted to the width of the curled portions at both ends of the elastic portion 22. When the motherboard bracket 42 is installed on the motherboard 41 to position the camera body 10, the limiting bone position 421 presses down from directly above the elastic portion 22, so that the first curled portion 221 and the third curled portion 223 at both ends of the elastic portion 22 are just accommodated in the groove structure 422, thereby achieving a tight locking of the camera body 10.

[0043] In this embodiment, the electronic connector 32 on the flexible circuit board 30 is engaged with the connector on the motherboard 41, causing the middle part of the first circuit board 31 to be bent.

[0044] Specifically, when the flexible circuit board 30 is not installed on the motherboard 41, it is in a flat state. When the electronic connector 32 on it covers the upper surface of the first circuit board 30 and is fastened onto the motherboard 41, the pressure on the first circuit board 30 causes the middle part of the first circuit board 31 to bend. This transfers the force that causes the first circuit board 31 to change from a straight state to a bent state from the motherboard bracket 42 to the supporting spring 20. Furthermore, when the motherboard bracket 42 is installed downwards, the bending force of the first circuit board 31 pushes the camera body 10 onto the limiting bone 421 on the motherboard bracket 42. In other words, the bending force of the first circuit board 31 and the limiting bone 421 securely position the two sides of the camera body 10.

[0045] According to some embodiments of the present application, the support part 21 is welded on the main board 41 by patching. In this way, the support part 21 can be firmly connected with the main board 41, and the surface contact of the two can be facilitated.

[0046] The assembling process and principle of the camera module provided in the embodiments of the present application will be described below in combination with Figure 2 and Figure 3

[0047] First, the camera body 10 is contacted to the camera pre-positioning support spring 20, and then the BTB (electronic connector 32) on the camera FPC (flexible circuit board 30) is buckled on the BTB of the main board 41. In this way, the camera FPC is bent, and the force of changing the camera FPC from straight to the bent state is transferred from the main board support 42 to the camera pre-positioning support spring 20. Then the main board support 42 is assembled, and when the main board support 42 is assembled to a certain height, the limit bone position 421 on the main board support 42 will start to contact the elastic part 22 of the camera pre-positioning support spring 20. When the limit bone position 421 on the main board support 42 just contacts the elastic part 22, the limit bone position 421 on the main board support 42 starts to limit the camera body 10, as shown in Figure 2 When the main board support 42 continues to be assembled, the limit bone position 421 on the main board support 42 will start to pull open the elastic part 22, and at the same time, due to the bending force of the camera FPC, the camera body 10 will be pushed to the limit bone position 421 on the main board support 42, so that the camera body 10 is finally limited by the main board support 42, as shown in Figure 3 In this way, the problems of the traditional and current market mobile phone camera positioning structure, such as the manufacturing tolerance, assembly tolerance, too long size chain leading to damage of the camera, and excessive tilt optical axis angle and eccentricity, are well solved.

[0048] The electronic device according to the embodiments of the present application comprises: a circuit board assembly and the camera module, the circuit board assembly comprises a main board and a main board support, the camera module is arranged on the circuit board assembly, and the connector on the flexible circuit board is buckled with the connector on the main board. In this way, the camera body is pre-positioned by the elastic part of the support spring, and when being installed in the electronic device, the camera body is secondarily positioned by the main board support, so that the camera body is not easy to deviate from the center position, and the damage of the camera can be reduced.

[0049] Other components of the electronic device according to the embodiments of the present application, such as processors and controllers, and operations are known to those skilled in the art, and will not be described in detail here.

[0050] ​The application solves the problems of camera assembly damage, excessive tilt optical axis angle and eccentricity caused by part manufacturing tolerance, assembly tolerance and too long size chain by designing a patch on the mainboard and a pull patch bone on the mainboard support.
