Vehicle-mounted camera module structure

Abstract

The invention relates to a vehicle-mounted camera module. The camera module comprises a lens (1), a front shell (2) assembled with the lens (1), and a circuit board (3) fixedly connected with the front shell (2), the camera is characterized in that the camera also comprises a sealing ring (4), and the sealing ring (4) comprises a first part (41) in sealing connection with the front housing (2), asecond part (42) in sealing fit with the circuit board (3), and a third part (43) which is located between the first part (41) and the second part (42) and is in sealing connection with the lens (1).According to the vehicle-mounted camera module, while the image sensor is isolated from the external environment, the assembly position of the lens and the front shell is also isolated outside, the defect that a conventional vehicle-mounted camera module structure cannot isolate the assembly of the lens and the front shell is effectively overcome, and the dustproof effect is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted cameras, in particular to a structure of a vehicle-mounted camera module with a dustproof structure. Background technique [0002] With the development of economy and technology, the trend of automobile automation and intelligence has made the importance of vehicle camera modules increasingly prominent. Now drivers are increasingly relying on car camera modules for assisted driving, especially in blind spot detection, collision warning and automatic driving. In order to ensure driving safety, higher and higher requirements are also put forward for vehicle camera modules. [0003] In terms of vehicle camera imaging, how to solve the stain problem has always been one of the research directions in this field. The existence of smudges will degrade the picture quality of the image, affect the picture effect, and even cause the algorithm to make wrong judgments, issue wrong actions or instruct...

AI Technical Summary

Problems solved by technology

[0004] 1. Failure to consider the impact of impurities such as debris generated when the lens is assembled with the front case on imaging;

[0005] 2. In the existing solution, when the lens is focused, the dust-proof sealing ring will move with the rotation of the lens, and then the friction will generate debris or impurities, or cause the sealing ring to wrinkle and fail.
