Can the Rearview Mirror Fold Outward?
1 Answers
Rearview mirrors can fold outward. Car rearview mirrors are located on the left and right sides of the front of the car, as well as inside the front of the car. The rearview mirrors reflect the conditions behind, beside, and below the car, allowing the driver to indirectly see these areas clearly. They serve as the "second pair of eyes," expanding the driver's field of vision. Structural Principle of Rearview Mirrors: Rearview mirrors have a field of view issue, which refers to the range that the mirror surface can reflect. The industry has proposed three 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 curvature radius of the rearview mirror. There is a certain relationship among these three elements. When the distance and size of the rearview mirror are the same, the smaller the curvature radius of the mirror surface, the larger the field of view reflected by the mirror. 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. Reflectivity Index of Rearview Mirrors: Rearview mirrors also have a reflectivity index. The higher the reflectivity, the clearer the image reflected by the mirror surface. The level of reflectivity is related to the reflective film material on the inner surface of the mirror.
