Abstract

The invention discloses an automobile rearview mirror with a color-changing property and a manufacturing method thereof. The structures and manufacturing techniques for electrochromism components are improved. The automobile rearview mirror has the characteristic of self-energy supply. Besides, the color-changing response time is short, the service life is prolonged and the freezing resistance is excellent; the rearview mirror can change the color according to the light intensity, so that the user can have a clear view field; the method provided by the invention is simple and easy in operation; the automobile rearview mirror is easy to be industrially produced.

Description

technical field [0001] The invention belongs to the field of automobiles, and more specifically relates to an automobile rearview mirror with color-changing performance and a manufacturing method thereof. Background technique [0002] In conventional technology, car rearview mirrors generally do not have an automatic color-changing function, and are generally located on the left and right sides of the car head, as well as in front of the car interior, and generally use the principle of mirror reflection to check the road conditions behind the car. [0003] However, the stronger light irradiation of the rear car will make the driver blind for a short time, which is easy to cause traffic accidents. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present invention aims at the problems existing in the background technology. It improves the structure and manufacturing process of the electrochromic device, so that it ...
