Description

Technical Field

[0001] The utility model relates to the technical field of light-changing structures, in particular to a light-changing structure for a dual-lamp automobile lens. Background Art

[0002] A dual-light car lens refers to a xenon headlight that uses the same light source for both high and low beams. However, since the high and low beams of a dual-light car lens are integrated into the same lens, it is necessary to distinguish between the high and low beams. A more common practice is to install a dimming structure to achieve the purpose of switching between high and low beams. Usually, the switching between high and low beams is achieved by rotating the shading sheet. In this way, only one xenon bulb is needed to achieve the switching between high and low beams.

[0003] Chinese patent application number: CN201610235046.0 discloses a dimming structure for dual-light automobile lenses, which adopts a method of flipping an arc-shaped sunshade downward so that the vertical movement component during the flipping process is greater and the dimming speed is faster. In special circumstances, rapid switching between high and low beams can give the driver more reaction time, thereby avoiding traffic accidents.

[0004] Although the above patent realizes the function of assisting the dual-light automobile lens to dim, the above patent has the following disadvantages when used: the above dimming structure for the dual-light automobile lens is fixedly installed on the shaft when in use. As the use time increases, the shading plate is easily attached with debris and damaged, and it is not convenient to quickly disassemble, clean and replace it. The operation steps are relatively cumbersome and inconvenient to use. Therefore, we propose a dimming structure for dual-light automobile lenses. Utility Model Content
