Problems solved by technology

Manual anti-dazzling rearview mirrors have great potential safety hazards because they need to be adjusted by hand during driving.
However, the automatic anti-glare interior rearview mirror has a relatively complex structure and many internal components, so most of them are designed to be thick and heavy. Even if there is a lightweight structural design, its strength is difficult to guarantee.

Abstract

The invention provides a lightweight anti-dazzling rearview mirror, comprising a housing, a circuit board, a liner plate, and a mirror body. The liner plate is an aluminum alloy core plate which is winded with carbon fibers. Two ends of the liner plate are provided with gaps. The circuit board is provided with a control chip and a light-sensitive element. The control chip is arranged on one end of the circuit board. The light-sensitive element is arranged on the other end of the circuit board. The gaps on two ends of the liner plate are corresponding to the positions of the control chips on two ends of the circuit board and the light-sensitive element. Also provided is a manufacturing method for the lightweight anti-dazzling rearview mirror. The method comprises steps of preparing the liner plate, manufacturing the mirror body, and assembling.

Description

technical field [0001] The invention relates to the technical field of automobile rearview mirrors, in particular to an anti-glare automobile rearview mirror with a lightweight structure and a manufacturing method thereof. Background technique [0002] Anti-glare rearview mirror refers to a car rearview mirror with anti-glare function, mainly to prevent the headlights of the car behind from shining on the rearview mirror when the light is too strong, causing the driver to feel dazzled and affecting the driver's attention force, resulting in traffic accidents. [0003] Anti-dazzling rearview mirror in the prior art mainly contains two kinds of manual anti-dazzling rearview mirror and automatic anti-dazzling rearview mirror. [0004] When a light source is projected onto a piece of wedge-shaped glass at close range, there will be two reflected lights with different strengths. The manual anti-glare rearview mirror is based on this principle, using a wedge-shaped glass with a ...
