Description
Technical Field
[0001] The present invention belongs to the technical field of cameras, and particularly relates to a camera module. Background Art
[0002] An in-vehicle camera generally includes a housing, a connector, and a camera. The connector and the camera are respectively installed on the housing, and then the housing is installed on an automobile. The connector is connected to devices such as the electric control circuit of the automobile to realize the function of shooting images of the in-vehicle camera.
[0003] In the existing technology, the connector is installed and fixed to the housing in a bonding manner. The static electricity on the connector may be conducted to the camera, causing electromagnetic interference to the camera and affecting the quality of the captured image. Summary of the Invention
[0004] The purpose of the present invention is to provide a camera module to solve the problem of electromagnetic interference of the camera.
[0005] To achieve the purpose of the present invention, the following technical solutions are provided:
[0006] An embodiment of the present invention provides a camera module, including a housing, a connector, a bonding member, and a grounding member. The housing is provided with a first through hole, at least a part of the connector is accommodated in the first through hole, the bonding member is disposed between the inner wall of the housing surrounding the first through hole and the connector, and the grounding member connects the housing and the connector. By connecting the connector and the housing through the grounding member, the static electricity of the connector can be introduced into the housing and grounded, solving the problem of electromagnetic interference of static electricity to the camera and ensuring the quality of the image captured by the camera.
[0007] In a possible implementation manner, the housing includes a bottom wall and a side wall. The bottom wall and the side wall enclose a cavity for accommodating the camera. The first through hole penetrates the bottom wall and communicates with the cavity. One end of the connector extends into the cavity and protrudes from the surface of the bottom wall. The first end of the grounding member abuts against the end of the connector protruding from the bottom wall, and the second end of the grounding member opposite to the first end is connected to the bottom wall. By the first end of the grounding member abutting against the end of the connector protruding from the bottom wall and the other end being connected to the bottom wall, the fixation of the grounding member is realized, and at the same time, the static electricity of the connector can be introduced from the first end to the bottom wall through the second end, reducing the static electricity on the connector and enhancing the static electricity protection effect of the camera.
[0008] In a possible implementation, the grounding member includes a main body, a first abutting portion, and a second abutting portion. A second through hole is provided in the middle of the main body to form a ring shape. The second through hole is used to receive the connector. The first abutting portion is provided on the inner wall of the second through hole of the main body to form the first end. The second abutting portion is provided on the outer periphery of the main body to form the second end. The static electricity of the connector flows to the bottom wall through the first abutting portion, the main body, and the second abutting portion, thereby improving the static electricity protection effect of the camera.
[0009] In a possible implementation, the main body covers the end of the adhesive member facing the cavity. Since the main body covers the adhesive member, static electricity on the connector is blocked by the main body when penetrating the adhesive member, and static electricity introduced into the main body will also flow to the bottom wall and will not be conducted to the camera, thereby improving the static electricity protection effect of the camera.
[0010] In a possible embodiment, the first abutting portion protrudes from a first surface of the main body, the first surface faces away from the adhesive component, the second abutting portion protrudes from a second surface of the main body opposite to the first surface, a first boss is provided on the periphery of one end of the connector protruding from the bottom wall, the first abutting portion abuts against the first boss, so that the first abutting portion is clamped between the first boss and the adhesive component, and the second abutting portion abuts against the surface of the bottom wall. Providing the first boss of the connector can ensure that there is a point of force for abutment between the first abutting portion and the connector, and then the second abutting portion abuts against the surface of the bottom wall. Since the connector is connected to the bottom wall in a fixed state through the adhesive component, the grounding member is also fixed, which can ensure the stability of the overall structure and the effectiveness of electrostatic protection.
[0011] In a possible embodiment, a clamping portion is further provided on the periphery of the main body, the clamping portion protrudes from the second surface, and the second abutting portion is arranged adjacent to the clamping portion; a protruding second boss is provided on the bottom wall, the second boss encloses the first through hole, and the first boss protrudes from the second boss, and the clamping portion is clamped on the surface of the second boss facing away from the first through hole. The second boss and the clamping portion are provided so that the grounding member can be more stably connected and fixed to the connector and the housing, thereby ensuring the stability of the overall structure and electrostatic protection.
[0012] In a possible implementation, there are multiple clamping parts, and there is a spacing distance between two adjacent clamping parts. Multiple clamping parts are arranged at intervals to facilitate the installation of the grounding member, save materials, and save costs.
[0013] In a possible implementation manner, the number of the first abutting portions and the second abutting portions is not less than two, and the not less than two first abutting portions and second abutting portions are arranged in an array relative to the center of the second through hole. This is beneficial to the stable connection between the grounding member, the connector and the bottom wall, and can provide stable and continuous electrostatic protection for the camera.
[0014] In a possible implementation manner, the first abutting portions and the second abutting portions are arranged alternately along the circumferential direction of the main body portion. The alternate arrangement can make the overall force of the grounding member more uniform, avoiding excessive force at a local position while too little force at other positions, which is prone to damage.
[0015] In a possible implementation manner, the first abutting portions and the second abutting portions are of a shrapnel structure. The shrapnel structure has elasticity, which is convenient for abutting against the connector and also ensures that the second abutting portion can be connected to the bottom wall.
[0016] In a possible implementation manner, a hollow socket portion is provided on the side of the bottom wall facing away from the cavity. The first through hole penetrates through the bottom wall and the socket portion, and a protruding clamping portion is provided on the outer periphery of the socket portion. The provision of the socket portion can protect the connector from damage, and the clamping portion is used for clamping with an external structure to fix the housing.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0030] The camera module provided by the embodiment of the present invention can be an in-vehicle camera module, which can export static electricity to the ground, solve the electromagnetic interference problem of static electricity on the camera, and ensure the quality of the picture captured by the camera. The camera module provided by the embodiment of the present invention can also be applied to mobile terminals, such as smart phones, tablet computers and other devices. The camera module provided by the embodiment of the present invention can also be applied to the security field, and can improve the picture imaging quality.
[0031] In one embodiment, please refer to Figure 1 and Figure 3 , the camera module includes a housing 10, a connector 20 and an adhesive member 30. The housing 10 is made of a metal material. Please refer to Figure 7 , the housing 10 is provided with a first through hole 102. At least part of the structure of the connector 20 is accommodated in the first through hole 102. The adhesive member 30 is disposed between the inner wall of the housing 10 surrounding the first through hole 102 and the connector 20. The adhesive member 30 is used to fix the connector 20 on the inner wall of the first through hole 102, so that the connector 20 and the housing 10 form an integral body. The housing 10 forms a cavity 101 for accommodating a camera (not shown in the figure). The connector 20 is used to connect the camera and external devices, so that the camera is powered on and receives control signals, and thus can work to output an image screen.
[0032] Since the connector 20 has static electricity, it is necessary to export the static electricity to avoid the influence of static electricity on the operation of the camera. Due to the setting of the bonding member 30, the bonding member 30 isolates between the connector 20 and the inner wall of the first through hole 102 of the housing 10, and the static electricity cannot be exported to the housing 10. At the position of the bonding member 30, the static electricity may penetrate to the camera, causing electromagnetic interference to the camera and resulting in unstable pictures output by the camera. Therefore, the purpose of this application is to solve the problem of electromagnetic interference caused by static electricity.
[0033] Please refer to Figure 2 and Figure 3 , in an embodiment, the camera module further includes a grounding member 40, and the grounding member 40 connects the housing 10 and the connector 20. Comparing Figure 1 and Figure 2 it can be seen that by connecting the connector 20 and the housing 10 through the grounding member 20, the static electricity of the connector 20 can be introduced into the housing 10 for grounding, solving the problem of electromagnetic interference of static electricity on the camera and ensuring the quality of the pictures taken by the camera.
[0034] Please continue to refer to Figure 7 , the housing 10 includes a bottom wall 11 and a side wall 12. The number of the side walls 12 is 4, and the 4 side walls 12 are connected to the bottom wall 11 to enclose the cavity 101 with the bottom wall 11. The cavity 101 houses the camera, and the side wall 12 can be used to fix the camera.
[0035] The first through hole 102 is opened on the bottom wall 11, penetrating the bottom wall 11 and communicating with the cavity 101. Please refer to Figure 4 , Figure 5 and Figure 7 , since the length of the connector 20 is relatively long and exceeds the thickness of the bottom wall 11, therefore, in order to protect the connector 20, a socket part 112 is provided on the side of the bottom wall 11 facing away from the cavity 101. The socket part 112 is a hollow sleeve structure, and the hollow area is communicated with and coaxial with the first through hole 101. The connector 20 is accommodated in the first through hole 102 of the bottom wall 11 and the hollow area of the socket part 112. Through the setting of the socket part 112, the connector 20 can be protected from being damaged. The hollow area of the socket part 112 can be a stepped hole with multiple steps, and a flange or other structures corresponding to the shape of the stepped hole in the hollow area of the socket part 112 can be provided on the outer periphery of the connector 20 so that the connector 20 can be better fixed.
[0036] Please refer to Figure 4 and Figure 7, a clamping portion 113 may be further provided on the outer periphery of the socket portion 112. The clamping portion 113 protrudes from the outer peripheral wall surface of the socket portion 112 and is used for clamping with an external structure, so as to fix the housing 10. In addition, a positioning member 15 may be further provided on the surface of the bottom wall 11 facing away from the cavity 101. The positioning member 15 is columnar and can extend into a hole provided on the external structure to achieve precise positioning of the position of the housing 10.
[0037] Please refer to Figure 5 and Figure 6 , one end of the connector 20 extends into the cavity 101 and protrudes from the surface 103 of the bottom wall 11. The first end of the grounding member 40 abuts against one end of the connector 20 protruding from the bottom wall, and the second end of the grounding member 40 opposite to the first end is connected to the bottom wall 11. By abutting the first end of the grounding member 40 against one end of the connector 20 protruding from the bottom wall and connecting the second end to the bottom wall 11, the fixing of the grounding member 40 is realized, and at the same time, the static electricity of the connector 20 can be introduced from the first end to the bottom wall 11 through the second end, reducing the static electricity on the connector 20 and enhancing the static electricity protection effect of the camera.
[0038] In one embodiment, please refer to Figure 4 , Figure 5 and Figure 10 and Figure 11 , the grounding member 40 includes a main body portion 41, a first abutting portion 43 and a second abutting portion 44. A second through hole 401 is formed in the middle of the main body portion 41 and is annular, such as circular. The second through hole 401 is used for receiving the connector 20. The connector 20 is sleeved in the annular structure of the main body portion 41, and the camera passes through the second through hole 401 to be connected to the connector 20. The first abutting portion 43 is provided on the inner wall of the first through hole 401 of the main body portion 41 to form the first end. The second abutting portion 44 is provided on the outer periphery of the main body portion 41 to form the second end. Through the above arrangement, the static electricity of the connector 20 flows to the bottom wall 11 through the first abutting portion 43, the main body portion 41 and the second abutting portion 44, improving the static electricity protection effect of the camera.
[0039] In one embodiment, the main body portion 41 covers one end of the bonding member 30 facing the cavity 101. Since the main body portion 41 covers the bonding member 30, the static electricity on the connector 20 is blocked by the main body portion 41 when penetrating the bonding member 30. The static electricity is introduced into the main body portion 41 and will also flow to the bottom wall 11 and will not be conducted to the camera, improving the static electricity protection effect of the camera.
[0040] In one embodiment, please refer to Figure 10 and Figure 11 , the number of the first abutting portion 43 and the second abutting portion 44 is not less than two. For example, the number of the first abutting portion 43 and the second abutting portion 44 can be any positive integer such as 2, 3, 4, 5... Figure 10 and Figure 11It is shown that the number of the first abutting portion 43 and the second abutting portion 44 is three. The first abutting portion 43 and the second abutting portion 44 with a number not less than two are arranged in an array relative to the center of the second through hole 401. Setting the number of the first abutting portion 43 and the second abutting portion 44 to be not less than two and arranging them in an array is conducive to the stable connection of the grounding member 40 with the connector 20 and the bottom wall 11, and can provide stable and continuous electrostatic protection for the camera.
[0041] In one embodiment, please refer to Figure 10 and Figure 11 , the first abutting portion 43 and the second abutting portion 44 are arranged alternately along the circumferential direction of the main body portion 41. The alternate arrangement can make the overall force on the grounding member 40 relatively uniform, avoiding excessive force on a local position while too little force on other positions, which is prone to damage.
[0042] In one embodiment, please refer to Figure 5 and Figure 11 , the first abutting portion 43 and the second abutting portion 44 are of a spring plate structure. The spring plate structure has elasticity, which is convenient for abutting against the connector 20 and also ensures that the second abutting portion 44 can be connected to the bottom wall 11.
[0043] In one embodiment, please refer to Figure 10 and Figure 11 , the first abutting portion 43 protrudes from the first surface 402 of the main body portion 41, the first surface 402 faces away from the adhesive member 30, and the second abutting portion 44 protrudes from the second surface 403 of the main body portion 41 opposite to the first surface 402.
[0044] Please refer to Figure 5 , Figure 6 and Figure 8 , the connector 20 includes a central portion 21 and a housing 22. The central portion 21 is a structure electrically connected to the camera, and the housing 22 is used to protect the central portion 21 and connect to the housing 10. A first boss 221 is provided on the outer periphery of one end of the housing 22 protruding from the surface 103 of the bottom wall 11. The first abutting portion 43 abuts against the first boss 221, and the first abutting portion 44 is clamped between the first boss 221 and the adhesive member 30, and the second abutting portion 44 abuts against the surface 103 of the bottom wall 11. Setting the first boss 221 of the connector 20 can make the first abutting portion 43 have a force application point for abutting against the connector 20. Then, by abutting the second abutting portion 44 against the surface 103 of the bottom wall 11, since the connector 20 is connected to the bottom wall 11 through the adhesive member 30 in a fixed state, the grounding member 40 is also fixed, which can ensure the stability of the overall structure and the effectiveness of electrostatic protection.
[0045] In one embodiment, please refer to Figure 10 and Figure 11, a clamping portion 42 is further provided on the outer periphery of the main body portion 41. The clamping portion 42 protrudes from the second surface 403, and the second abutting portion 44 is arranged adjacent to the clamping portion 42. Among them, the second abutting portion 44 includes a first portion 441 and a second portion 442. The structure of the first portion is the same as that of the clamping portion 42, and the second portion 442 extends from the first portion 441 toward the outer periphery of the main body portion 41.
[0046] Please refer to Figures 5 to 7 , a protruding second boss 111 is provided on the bottom wall 11. The second boss 111 encloses the first through hole 102, and the first boss 221 protrudes from the second boss 111. The clamping portion 42 is clamped on the surface 105 of the second boss 111 facing away from the first through hole 102. The second boss 111 surrounds the first through hole 102, and the inner wall surface 104 of the second boss 111 facing the first through hole 102 is used to connect with the bonding member 30. Please refer to Figure 9 , when the housing 10 is omitted, an annular groove 405 is formed between the bonding member 30 and the clamping portion 42 of the grounding member 40. The annular groove 405 is used to receive the second boss 111. The second boss 111 and the clamping portion 42 are provided to enable a more stable connection and fixation between the grounding member 40 and the connector 20 and the housing 10, ensuring the stability of the overall structure and electrostatic protection.
[0047] In one embodiment, please refer to Figure 10 and Figure 11 , the number of the clamping portions 42 is multiple, and there is a spacing distance between two adjacent clamping portions 42. The multiple clamping portions 42 are arranged at intervals, which makes it easy for the clamping portions 42 to be snapped into the second boss 111 when the grounding member 40 is installed, facilitating the installation of the grounding member 40. In addition, materials can be saved and costs can be reduced.
[0048] The above-disclosed is only a preferred embodiment of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby.
