[0002] The vehicle-mounted lens is mainly a vehicle-mounted camera, which is responsible for the vehicle's perception function. It is mainly used for vehicle parking assistance and vehicle front condition monitoring video. When the vehicle-mounted lens is in use, when light passes through a separate lens, part of the light will be reflected back. After the reflected light is reflected back and forth between the lens groups, part of the light will eventually pass through the lens to reach the sensor, forming a light spot, resulting in glare on the captured image.

[0003] When applying for the utility model, the applicant found through search that a Chinese patent disclosed "an anti-glare vehicle-mounted lens", and its application number is "CN202122538483.9".

A slider 202 is fixedly connected to the surface of the shell 201, and the slider 202 is installed inside the slide groove 103. The inner surface of the slide groove 103 is fixedly connected to a metal sheet 104, a magnet 203 is fixedly connected to the bottom of the slider 202, and the outer surface of the magnet 203 fits with the outer surface of the metal sheet 104. The slider 202 can move back and forth in the slide groove 103. When the slider 202 stops moving, the magnet 203 will be adsorbed on the metal sheet 104, thereby fixing the position of the shell 201. A moving groove 204 is provided on the outer surface of the shell 201, and a moving rod 207 is movably connected inside the moving groove 204. An adjustment plate 208 is fixedly connected to the bottom of the moving rod 207, and the adjustment plate 208 is located between the shell 201 and the outer frame 102. The moving rod 207 can move back and forth inside the moving groove 204 to adjust the position of the adjustment plate 208, thereby increasing the shading effect of the anti-glare mechanism 2.

[0032] Furthermore, if Figure 5-6 As shown, a telescopic hole 205 is provided at the rear side of the movable groove 204, and a spring 206 is fixedly connected inside the telescopic hole 205. One end of the spring 206 away from the telescopic hole 205 is fixedly connected to the outer surface of the movable rod 207.

A connecting thread is provided at the end of the lens body 101 away from the outer frame 102 to facilitate the installation of the lens body 101.

[0034] The working principle of the utility model is as follows: when in use, the position of the shell 201 can be adjusted by moving the shell 201 on the outer frame 102 forward and backward. After the position is adjusted, the magnetic block 203 will be adsorbed on the metal sheet 104 to fix the position of the shell 201. The push block 209 can also be pushed forward to allow the moving rod 207 to be stuck between the two elastic rods 211 to adjust the position of the adjustment plate 208 and fix the position of the adjustment plate 208, thereby blocking the light above and diagonally above the lens 1 to reduce the glare generated by the vehicle-mounted lens when shooting pictures. The anti-glare vehicle-mounted lens can effectively eliminate glare on the captured picture by blocking the light above and diagonally above the lens 1 to avoid light directly hitting the lens, and is easy to use.
