The use of wing mirror:
1. In order to facilitate the operation of the driver, prevent the occurrence of accidents due to driving safety, and ensure personal safety, rearview mirrors must be installed on the car, and all day rearview mirrors must be able to adjust the direction. The driver sits in the cab seat and directly obtains external information such as the rear, side, and bottom of the car.
2. The rearview mirror has a problem of the horizon, that is, the range that the mirror can reflect. The industry has a three-element formulation of the horizon, that is, the distance between the driver’s eyes and the rearview mirror, the size of the rearview mirror, and the radius of curvature of the rearview mirror.
3. When the distance and size of the rearview mirror are the same, the smaller the radius of curvature of the mirror surface, the larger the field of view reflected by the mirror surface. When the curvature radius of the mirror surface is the same, the larger the size of the mirror surface, the larger the field of view reflected by the mirror surface.
