Description

Technical Field

[0001] This utility model relates to the field of vehicle camera module technology, specifically to an ultra-slow rebound electrostatic conduction component. Background Technology

[0002] In the existing technology, as the requirements for visual perception accuracy of autonomous driving systems continue to increase, the reliability of vehicle cameras has become a key factor restricting the development of the technology. At present, the structural design of mainstream high-definition camera modules usually adopts a combination architecture of metal lens barrel and metal shell, and optical alignment bonding is achieved by 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] According to research, current AA (anti-abrasive) equipment on the market can complete the entire process from AA application to UV adhesive pre-curing within one minute. Therefore, there is an urgent need to design an ultra-slow-rebound electrostatic conduction component that exceeds one minute. To address this issue, we have proposed an ultra-slow-rebound electrostatic conduction component. Utility Model Content

[0005] The purpose of this invention is to provide an ultra-slow rebound electrostatic conduction component to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultra-slow rebound electrostatic conduction assembly, including a lens, a front shell, an optical sensor, an ultra-slow rebound electrostatic conduction unit, a circuit board assembly, a rear shell, and a Fakra connector. A receiving chamber is provided between the front and rear shells. The lens is located inside the front shell and is bonded together. The circuit board assembly is located within the receiving chamber formed by the front and rear shells, and an optical sensor is mounted on the circuit board assembly. The ultra-slow rebound electrostatic conduction unit is mounted on the circuit board assembly. The ultra-slow rebound electrostatic conduction unit is composed of a metal contact head, a shell, and non-temperature-sensitive slow rebound memory foam. The metal contact head is inserted inside the shell, and non-temperature-sensitive slow rebound memory foam is located inside the shell. The metal contact head and non-temperature-sensitive slow rebound memory foam are attached together, and the top of the metal contact head is attached to the bottom of the lens.

[0007] As a further preferred embodiment of this technical solution, the front shell and the rear shell are tightly connected by a bolt group, which is composed of bolts and nuts, and the bolts and nuts are fine-threaded.

[0008] As a further preferred embodiment of this technical solution, two sets of the ultra-slow rebound electrostatic conduction units are provided, and the two sets of ultra-slow rebound electrostatic conduction units are symmetrically distributed above the circuit board assembly.

[0009] As a further preferred embodiment of this technical solution, the metal contact head can slide inside the housing, and the top of the metal contact head is configured as a hemisphere.

[0010] This invention provides an ultra-slow rebound electrostatic conduction component, which has the following beneficial effects: This invention allows electrostatic charges to sequentially pass through the lens, the ultra-slow rebound electrostatic conduction unit, the circuit board assembly, and then be conducted to the outside via the housing and Fakra connector. This prevents electrostatic charges from accumulating on the camera module and being conducted to the optical sensor, thus avoiding damage to the optical sensor. It enhances the electrostatic protection capability of the anti-static camera module and strengthens the electrostatic shielding effect. By pressing the metal contact head down by 0.5mm through the lens, the device uses adhesive to stick the lens to the housing during the slow rebound of the metal contact head. After one minute, the metal contact head rebounds to the position where it contacts the lens and stops, making contact with the metal housing of the lens. Attached Figure Description

A receiving chamber is configured between the front shell 2 and the rear shell 6. The lens 1 is located inside the front shell 2 and is bonded together. The circuit board assembly 5 is disposed within the receiving chamber formed between the front shell 2 and the rear shell 6, and the optical sensor 3 is disposed on the circuit board assembly 5. The ultra-slow rebound electrostatic conduction unit 4 is disposed on the circuit board assembly 5. The electrostatic discharge unit 4 is composed of a metal contact head 8, a housing 9, and a non-temperature-sensitive slow-rebound memory foam 10. The metal contact head 8 is inserted inside the housing 9, and the non-temperature-sensitive slow-rebound memory foam 10 is disposed inside the housing 9. The metal contact head 8 and the non-temperature-sensitive slow-rebound memory foam 10 are in contact with each other. The top of the metal contact head 8 is attached to the bottom of the lens 1. Electrostatic charge can pass sequentially through the lens 1, the ultra-slow-rebound electrostatic discharge unit 4, the circuit board assembly 5, and then be conducted to the outside through the housing and the Fakra connector 7, thereby preventing the accumulation and conduction of electrostatic charge on the camera module. To prevent damage to the optical sensor, this anti-static camera module enhances its electrostatic protection capabilities and shielding effect. The metal contact head 8 is pressed down 0.5mm through the lens 1. During the slow rebound of the metal contact head 8, the device uses adhesive to bond the lens 1 to the housing. After one minute, the metal contact head 8 rebounds to its contact position with the lens 1 and comes into contact with the metal housing of the lens 1. The front housing 2 and the rear housing 6 are tightly connected by a bolt group, which consists of bolts and nuts with fine-pitch threads. The threaded connection effectively improves the stability of the connection between parts. The ultra-slow rebound electrostatic conduction unit 4 is provided in two sets, which are symmetrically distributed above the circuit board assembly 5 to further prevent electrostatic charge from accumulating on the camera module and being conducted to the optical sensor, thus preventing damage to the optical sensor. The metal contact head 8 can slide inside the housing 9. The top of the metal contact head 8 is set as a hemisphere, which can concentrate the transmitted force to the central area of ​​the metal contact head 8 to facilitate the downward pressing of the non-temperature-sensitive slow rebound memory foam 10.

[0015] This utility model provides an ultra-slow rebound electrostatic conduction component, the specific working principle of which is as follows: In this device, electrostatic charge sequentially passes through the lens 1, the ultra-slow rebound electrostatic conduction unit 4, the circuit board assembly 5, and is conducted to the outside via the housing and Fakra connector 7. This prevents electrostatic charge from accumulating on the camera module and being conducted to the optical sensor, thus avoiding damage to the optical sensor. This enhances the electrostatic protection capability of the anti-static camera module and strengthens the electrostatic shielding effect. By pressing the metal contact head 8 down 0.5mm through the lens 1, the device uses adhesive to bond the lens 1 to the housing during the slow rebound of the metal contact head 8. After one minute, the metal contact head 8 rebounds to the position where it contacts the lens 1 and comes into contact with the metal housing of the lens 1. This effectively improves the electrostatic protection capability and strengthens the electrostatic shielding effect of the anti-static camera module. Furthermore, it is ready for mass production, as the ultra-slow rebound electrostatic conduction unit 4 can be mounted onto the circuit board assembly 5 using an SMT placement machine.
