Background technique

The car rearview mirror is a very important part of the car, and the car rearview mirror is located on the left and right sides of the front row of the car. The car rearview mirror can intuitively reflect the situation behind, side and below the car, so that the driver can indirectly see the vehicles and pedestrians driving in these positions, and it expands the driver's field of vision.

As shown in Figure 1, the traditional car rearview mirror is installed next to the windshield glass of the car door, which cannot completely collect all the image information around the car body, and will form a large blind spot behind the car. If there are obstacles and pedestrians in the driving blind spot, it is very easy to cause the driver's judgment and operation error, and cause road traffic accidents, reducing the safety of the car.

Traditional car rearview mirrors are installed outside the car, especially on the side of the door windshield and the fender next to the engine compartment cover. When the car is running at high speed, the external rearview mirror has greater resistance to the car. , reducing fuel economy. When the car is driving in foggy or rainy and snowy days, it will cause fog, frost and water accumulation on the mirror surface of the rearview mirror, which will cause the driver's vision to be unclear and affect the driver's judgment of pedestrians and vehicles on the side and rear; in order to improve the vision Therefore, the driver needs to stretch out the window from time to time to clean the lens surface of the rearview mirror, which is not only extremely inconvenient, but also has a strong impact on driving safety.
