Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to an anti-static camera module. Background Technology

[0002] In existing technologies, as the requirements for visual perception accuracy in autonomous driving systems continue to increase, the reliability of vehicle cameras has become a key factor restricting technological development. Currently, the structural design of mainstream high-definition camera modules typically adopts a combination of a metal lens barrel and a metal housing, and optically aligns and bonds them using AA (Active Alignment) adhesive.

[0003] While this metal-adhesive composite structure meets basic assembly requirements, it creates a discontinuous insulating interface layer between the lens barrel and the housing. Furthermore, since assembly gaps between metal components are unavoidable, when electrostatic charges from the external environment penetrate the module along the metal conduction path, these charges directly reach the imaging chip, easily causing electrostatic breakdown faults in semiconductor devices and resulting in irreversible imaging function failure.

[0004] Therefore, there is an urgent need to design an anti-static camera module to solve the above technical problems. Utility Model Content

The limiting post abuts against the body and is configured to prevent the body from rotating in a second direction opposite to the first direction.

[0015] As an optional technical solution for an anti-static camera module, the circuit board assembly includes a first circuit board with an assembly hole facing the screwing component. The assembly hole is configured to allow an installation tool to extend into and screw the screwing component.

[0016] As an optional technical solution for an anti-static camera module, the housing includes a first housing and a second housing. The anti-static camera module also includes a first fixing member and a sealing ring. The sealing ring is disposed between the first housing and the second housing. The first fixing member passes through the first housing and the second housing and causes the first housing and the second housing to press against the sealing ring.

[0017] As an optional technical solution for an anti-static camera module, the circuit board assembly further includes a second circuit board, which is stacked on top of the first circuit board and located above the first circuit board at a predetermined distance.

[0021] As an optional technical solution for an anti-static camera module, the anti-static camera module further includes an RF connector and a fourth fixing member, the fourth fixing member being inserted through the RF connector and connected to the housing; and one end of the RF connector extending into the receiving cavity and being signal-connected to the circuit board assembly.

[0024] The above describes a method for conducting static electricity by creating a contact element inside the housing, with one end connected to the housing and the other end resting on the outer wall of the camera. When the camera is subjected to static interference from the external environment, the static charge can be conducted from the camera to the contact element, then from the contact element to the housing, and finally from the housing to the external environment. This prevents static charge from accumulating on the camera and being conducted to the optical sensor, thus avoiding damage to the optical sensor. This improves the protection of the optical sensor, enhances the electrostatic protection capability of the anti-static camera module, strengthens the shielding effect, and improves reliability and safety. The structural design of this anti-static camera module overcomes the problem of static charge accumulation caused by traditional AA glue insulation layers, significantly improving the reliability and safety of the camera.

[0046] Example 1

[0047] This embodiment provides an anti-static camera module that improves electrostatic protection capabilities and enhances the effect of electrostatic shielding.

[0048] like Figures 1-6 As shown, the anti-static camera module mainly includes a housing 10, a camera 20, a circuit board assembly 30, and a contact 40. The housing 10 has a receiving cavity. At least a portion of the camera 20 passes through the housing 10 and is housed within the receiving cavity, and the camera 20 is bonded to the housing 10. The circuit board assembly 30 is disposed within the receiving cavity, and an optical sensor is mounted on the circuit board assembly 30. The contact 40 is disposed within the receiving cavity, with one end connected to the housing 10 and the other end overlapping the outer wall of the camera 20; this allows electrostatic charge to pass sequentially through the camera 20 and the contact 40 and be conducted to the outside by the housing 10.

[0049] Based on the above design, this embodiment forms an electrostatic charge conduction path by providing a contact member 40 inside the housing 10, with one end of the contact member 40 connected to the housing 10 and the other end of the contact member 40 overlapping the outer wall of the camera 20. Figure 3 The bold black arrows in the diagram indicate the electrostatic charge conduction path. When the camera 20 is subjected to electrostatic interference from the external environment, the electrostatic charge can be conducted from the camera 20 to the contact 40, then from the contact 40 to the housing 10, and finally from the housing 10 to the external environment (e.g., to the device's grounding terminal). This prevents electrostatic charge from accumulating on the camera 20 and being conducted to the optical sensor, thus avoiding damage to the optical sensor. It improves the protection of the optical sensor, enhances the electrostatic protection capability of the anti-static camera module, strengthens the shielding effect, and improves reliability and safety. The structural design of the anti-static camera module in this embodiment overcomes the problem of electrostatic charge accumulation caused by traditional AA glue insulation layers, significantly improving the reliability and safety of the camera 20.

[0050] It is understood that the outer wall of the housing 10, the camera 20, and the contact 40 in this embodiment are all made of metal, which facilitates the conduction of static electricity.

[0051] In some alternative implementations, the anti-static camera module can be installed in a vehicle as an automotive camera module. Exemplarily, it can be installed on the windshield (i.e., a dashcam), rear of the vehicle (i.e., a reversing camera), grille or rearview mirror housing (ADAS), or below the rearview mirror (DMS). The automotive camera used can be a dashcam camera, reversing camera, 360° surround view camera, ADAS camera (Advanced Driver Assistance System), in-vehicle camera (DMS driver monitoring), or other monitoring, recording, or driver assistance camera devices. It can analyze road conditions, recognize pedestrians, and perform gesture control in real time, providing real-time information to the driver or monitoring the driver's status, thus ensuring safe driving.

[0052] like Figures 4-5 As shown, in this embodiment, a fixing position is provided on the bottom wall of the accommodating chamber. The anti-static camera module also includes a screwing component 50, which screws one end of the contact member 40 along a first direction and fixes it in the fixing position. The first direction is... Figure 5 The clockwise direction (X1) is shown in the figure. For example, the screw 50 can be configured as a conventional component such as a fastening screw or a fastening bolt.

[0053] Specifically, the contact 40 has a body 42 and a first end 41 and a second end 43 disposed at both ends of the body 42. The body 42 is wound around the screw-on member 50. The first end 41 forms a stress relief port 44 with the body 42, and the second end 43 overlaps the outer wall of the camera 20. This bending of the first end 41 and its formation of the stress relief port 44 with the body 42 releases assembly stress when the screw-on member 50 is rotated, preventing plastic deformation of the contact 40. Simultaneously, if the screw-on member 50 is not tightened, but the second end 43 of the contact 40 has already overlapped the outer wall of the camera 20, the stress relief port 44 prevents deformation and displacement of the contact 40 when the operator continues to tighten the screw-on member 50. It is understood that the size of the stress relief port 44 gradually decreases in this situation.

[0054] Furthermore, in this embodiment, a limiting post 13 is also provided on the bottom wall of the accommodating chamber. The limiting post 13 abuts against the body 42 and is configured to prevent the body 42 from rotating in a second direction (counterclockwise X2) opposite to the first direction (clockwise direction). In other words, the limiting post 13 can prevent the contact member 40 from rotating in the opposite direction, thus preventing the connection from becoming loose and avoiding the phenomenon that the contact member 40 does not contact the outer wall of the camera 20.

[0055] like Figure 6As shown, the circuit board assembly 30 in this embodiment includes a first circuit board 31, on which an assembly hole 311 is provided. The assembly hole 311 is positioned directly opposite the screwing component 50 and is configured to allow an installation tool to extend into and screw the screwing component 50. The assembly hole 311 facilitates the vertical insertion of the installation tool into the screwing component 50, thereby solving the assembly problem in confined spaces.

[0056] For example, the installation tool can be set as an electric screwdriver, screwdriver, etc.

[0057] like Figures 1-2 As shown, the housing 10 in this embodiment includes a first housing 11 and a second housing 12. The anti-static camera module also includes a first fixing member 14 and a sealing ring 15. The sealing ring 15 is disposed between the first housing 11 and the second housing 12. The first fixing member 14 passes through the first housing 11 and the second housing 12, causing the first housing 11 and the second housing 12 to press against the sealing ring 15. By designing the housing 10 as a split type with the first housing 11 and the second housing 12 being detachably connected, the maintenance and repair of the anti-static camera module is facilitated. The sealing ring 15 between the first housing 11 and the second housing 12 improves the waterproof and sealing performance of the housing 10.

[0058] like Figure 6 As shown, the circuit board assembly 30 also includes a second circuit board 32, which is stacked on top of the first circuit board 31 and positioned above it with a predetermined distance. In other words, the three-dimensional stacking design of the first circuit board 31 and the second circuit board 32 not only improves the integration of the circuit board assembly 30 and reduces its size, thus miniaturizing the anti-static camera module structure and reducing costs, but also improves the heat dissipation efficiency of the electronic components on the first circuit board 31 and the second circuit board 32 by maintaining a predetermined distance between them, thereby enhancing safety.

[0059] Furthermore, the circuit board assembly 30 in this embodiment also includes a second fixing member 33 and a third fixing member 34; the second housing 12 is provided with a connecting post 16, and the first circuit board 31 is provided with a clearance position 312. The second fixing member 33 passes through the first circuit board 31 and is connected to the second housing 12, and the third fixing member 34 passes through the second circuit board 32 and passes through the clearance position 312 to connect to the connecting post 16. Exemplarily, the first circuit board 31 can be directly fixed to the second housing 12 with a short bolt, and the second circuit board 32 can be locked to the connecting post 16 with a long bolt that passes through the clearance position 312 of the first circuit board 31.

[0060] For example, the first fixing member 14, the second fixing member 33 and the third fixing member 34 in this embodiment can all be set as bolts, screws, etc.

[0061] In this embodiment, the contact 40 is detachably mounted on the inner wall of the second housing 12 via the screwing member 50.

[0062] like Figures 1-3 As shown, the anti-static camera module also includes an adhesive layer 60. A boss 21 protrudes from the outer wall of the camera 20. One side of the adhesive layer 60 is connected to the boss 21, and the other side of the adhesive layer 60 is connected to the housing 10. The adhesive layer 60 improves the stability and reliability of the connection between the camera 20 and the housing 10, and reduces the shaking of the camera 20.

[0063] In some alternative implementations, the adhesive layer 60 may be set as AA adhesive.

[0064] In some alternative embodiments, the adhesive layer 60 can be configured as a conductive adhesive, thereby forming an auxiliary conductive path for electrostatic charges and improving the efficiency of electrostatic charge conduction.

[0065] like Figures 1-3 As shown, the anti-static camera module also includes an RF connector 70 and a fourth fixing member 71. The fourth fixing member 71 passes through the RF connector 70 and is connected to the housing 10; and one end of the RF connector 70 extends into the receiving cavity and is connected to the circuit board assembly 30 via signal.

[0066] For example, the RF connector 70 is fixed to the top of the first housing 11 by bolts (fourth fastener 71), and its internal probes pass through the first housing 11 to connect with the electronic components of the second circuit board 32. The other end of the RF connector 70 is connected to a cable in the vehicle wiring harness, thereby forming a video transmission channel, so that the image captured by the camera 20 can be transmitted to the vehicle display screen through the RF connector 70.

[0067] Example 2

[0068] like Figure 7 As shown, this embodiment provides an assembly method for an anti-static camera module, which is used to assemble the anti-static camera module in Embodiment 1. The assembly method for the anti-static camera module includes the following steps:

[0069] A contact 40 is installed on the inner wall of the accommodating chamber of the housing 10, so that the contact 40 is in the first mounting position.

[0070] Specifically, a contact 40 is installed inside the second housing 12, and the position of the contact 40 at this time is as follows: Figure 4As shown, the contact 40 is positioned to avoid the through hole on the housing 10, which facilitates the subsequent insertion of the camera 20 through the through hole into the receiving chamber inside the housing 10, thus preventing interference or collision between the camera 20 and the contact 40 during installation.

[0071] Furthermore, the step also includes wrapping the body 42 of the contact 40 around the screw 50, and installing the screw 50 and the contact 40 together in the second housing 12.

[0072] The contact 40 is fixed at one end to the fixed position on the bottom wall of the accommodating chamber by the screwing component 50, and the first end 41 of the contact 40 and the body 42 form a pressure relief port 44. At the same time, the limiting post 13 on the bottom wall of the accommodating chamber abuts against the body 42 of the contact 40, restricting the contact 40 from rotating in the counterclockwise direction, and preventing the contact 40 from not contacting the outer wall of the camera 20.

[0073] The circuit board assembly 30 is assembled into the receiving cavity of the housing 10.

[0074] Specifically, the first circuit board 31 in the circuit board assembly 30 is fixed to the second housing 12 by the second fastener 33, and the mounting hole 311 of the first circuit board 31 is aligned with the screwing member 50 inside the second housing 12.

[0075] The second circuit board 32 is stacked on top of the first circuit board 31 and fixed to the connecting post 16 of the second housing 12 by the third fixing member 34 passing through the clearance position 312 of the first circuit board 31, so that the second circuit board 32 and the first circuit board 31 form a preset distance.

[0076] One end of the camera 20 passes through the housing 10 and extends into the receiving cavity, so that the end of the camera 20 is higher than the height of the contact member 40; and the camera 20 is bonded to the housing 10.

[0077] Specifically, the protrusion 21 on the camera 20 is bonded to the second housing 12 using AA glue, forming a stable structure to prevent the camera 20 from shaking during use. The end of the camera 20 is higher than the height of the contact 40, which facilitates the subsequent bonding of the contact 40 to the outer wall of the camera 20, forming an electrostatic charge conduction path of "camera 20—contact 40—housing 10". Figure 3 The bold black arrows in the image represent the electrostatic charge conduction paths, thus preventing the risk of open circuits.

[0078] The contact 40 is screwed through the circuit board assembly 30 to the second mounting position so that the end of the contact 40 overlaps the outer wall of the camera 20.

[0079] Specifically, the operator can use an electric screwdriver or other torque tool to screw the screwing part 50 clockwise through the assembly hole 311, so that the contact part 40 rotates from the first mounting position to the second mounting position. At this time, the end of the contact part 40 overlaps the outer wall of the camera 20, thereby forming an electrostatic charge conduction path of "camera 20 - contact part 40 - housing 10".

[0080] By assembling the circuit board assembly 30 first and then the camera 20, the light distance of the camera 20 can be easily adjusted, thus improving the assembly efficiency.

[0081] The assembly method for the anti-static camera module also includes the following steps:

[0082] The second circuit board 32 in the circuit board assembly 30 is mounted on the connecting post 16 of the second housing 12 via the third fixing member 34. The second fixing member 33 and the third fixing member 34 are arranged diagonally to improve local stress and avoid stress concentration. Specifically, one end of the third fixing member 34 passes through the clearance 312 on the first circuit board 31 and is connected to the connecting post 16.

[0083] The first housing 11 and the second housing 12 are detachably connected by the first fastener 14, so that the first housing 11 and the second housing 12 are interlocked to form a receiving cavity. The circuit board assembly 30 is housed in the receiving cavity.

[0084] The fourth fastener 71 is used to fix the radio frequency connector 70 on the first housing 11, and one end of the radio frequency connector 70 is inserted into the accommodating cavity and connected to the signal of the second circuit board 32. The other end of the radio frequency connector 70 is connected to the cable in the vehicle wiring harness, thereby forming a video transmission channel, so that the image captured by the camera 20 can be transmitted to the vehicle display screen through the radio frequency connector 70.

[0085] The assembly method of this anti-static camera module is simple. Before assembling the camera 20, the contact 40 is positioned in a first mounting position to avoid the through-hole on the housing 10. After assembling the camera 20, the contact 40 is screwed into a second mounting position, overlapping with the outer wall of the camera 20, thus forming an electrostatic charge conduction path of "camera 20—contact 40—housing 10". This improves the electrostatic protection capability of the anti-static camera module and enhances its electrostatic shielding effect.
