Description

Technical Field

[0001] The utility model relates to a rear-view mirror for automobiles, in particular to an electrochromic lens rear-view mirror which can change color through conduction after sensing light, thereby changing the reflectivity to produce an anti-glare function. Background Art

[0002] With the advancement of technology, most car rearview mirrors use electrochromic rearview mirrors that change color with the environment, so as to change the reflectivity of the car rearview mirror with the change of environment to prevent glare. Since the car rearview mirror needs to be powered on at the periphery of the glass of the rearview mirror, in order to avoid the power connection design being exposed on the glass, a plastic shell is used to cover the periphery of the glass of the rearview mirror, or a decorative edge is electroplated on the periphery of the glass closest to the user. The decorative edge cannot change color, but the inside of the decorative edge can change color. However, the color difference between the current decorative edge and the color-changing part is large, and it can be clearly seen that there is a circle of electroplated decorative edge around the periphery of the rearview mirror, which greatly affects the appearance of the car rearview mirror.
