What is the appropriate position to adjust car rearview mirrors?
1 Answers
Adjust the rearview mirror so that the car body occupies 1/4 of the mirror surface. Below is relevant information about rearview mirrors: 1. Classification: interior rearview mirror, exterior rearview mirror, and downward-view mirror. 2. Structural principle: Rearview mirrors involve a field of view issue, which refers to the range the mirror surface can reflect. The industry proposes three key elements of the field of view: 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. These three elements are interrelated. When the distance and size of the rearview mirror are the same, a smaller radius of curvature of the mirror surface results in a larger reflected field of view. When the radius of curvature is the same, a larger mirror size provides a larger reflected field of view. Additionally, rearview mirrors have a reflectivity index. Higher reflectivity yields clearer images reflected by the mirror. The level of reflectivity depends on the reflective film material on the inner surface of the mirror. As the speed of general passenger cars increases, wind resistance and noise become important considerations for designers. Therefore, the exterior rearview mirror's contour must comply with aerodynamics, using smooth lines to minimize wind resistance and noise.
