Problems solved by technology

[0003] However, in the waterproof structure of the front face of the existing vehicle-mounted camera module, the joint between the lens and the housing leaks on the impact surface. When encountering high-pressure flushing, the edge of the joint is prone to warping, resulting in high-pressure flushing. Water directly hits the inside of the camera module, causing water seepage or even washing away the internal components, seriously affecting the imaging performance of the camera module

Abstract

The invention relates to a camera module waterproof structure. The camera comprises a lens (1) and a shell (2) fixedly connected with the lens (1), the camera is characterized in that the lens (1) isprovided with a step structure (11), the step structure (11) comprises a first side surface (111) and a second side surface (112) which are connected in sequence, the shell (2) is provided with a matching surface (21) which is connected with the second side surface (112) in a matching manner, and the height of the first side surface (111) is greater than that of the shell (2); and surface rough structures (3) which are matched with each other are arranged on the second side surface (112) and the matching surface (21). According to the camera module waterproof structure, the waterproof effect can be effectively improved, and the matching sealing performance of the lens and the shell is better.

Description

technical field [0001] The invention belongs to the technical field of camera equipment protection, and in particular relates to a camera module waterproof structure. Background technique [0002] With the continuous maturity of optical imaging technology and the high demand trend of the market, the requirements for waterproof performance of various camera modules are also getting higher and higher. Taking the car camera module as an example, drivers nowadays rely more and more on the camera module for assisted driving, such as blind spot detection, collision warning, and automatic driving. In order to ensure driving safety, the reliability requirements for the vehicle camera module are very high, especially the waterproof requirements. For this reason, some corresponding lens front face waterproof structures have been designed in the industry, and its function is to prevent water or other liquids from entering the inside of the camera through the front face of the camera, ...
