Problems solved by technology

[0002] Car lights, also known as car headlights and car LED daytime running lights, as the eyes of a car, are not only related to the external image of a car owner, but also closely related to driving at night or in bad weather. Aesthetics and lighting effect choose to refit the car headlights into xenon headlights. The light of xenon headlights is cool white light, which has poor penetrating power in foggy weather and poor lighting effects. It is necessary to switch to fog lights with yellow light. It is inconvenient to adjust the light and the brightness of the fog lamp is not enough

Embodiment 1

[0025] refer to Figure 1-3 , a dimming device for automobile lights, comprising a mounting shell 1, the inner arc surface of the mounting shell 1 is connected with a car lamp body 3 by bolts, and the top inner wall and the bottom inner wall of the mounting shell 1 are connected by two bolts with The transparent plate 2 that car lamp body 3 is arranged in parallel forms a cavity between the two transparent plates 2, and the top outer wall of the installation housing 1 is provided with a movable rod 8 through a driving mechanism, and the bottom of the movable rod 8 is connected with a transparent rod 8 by bolts. The lifting plate 4 vertically arranged on the plate 2, the lifting plate 4 is located inside the cavity, the outer wall of the installation shell 1 is connected with the storage shell 11 by bolts, and the inner wall of one side of the storage shell 11 and the outer wall of the installation shell 1 The same partition 16 is connected by bolts, the top of the partition 16...

Embodiment 2

[0035] refer to Figure 4 , a dimming device for automobile lamps. Compared with Embodiment 1, this embodiment has a groove 22 on the end of the sealing sheet 18 extending to the inside of the through hole, and the opening position of the groove 22 and the bottom of the fixing rod 19 corresponding to the end position.

[0036] Working principle: the fixed rod 19 is inserted into the groove 22 to push the sealing sheet 18, so as to avoid sliding when the fixed rod 19 pushes the sealing sheet 18.

Abstract

The invention discloses a dimming device for an automobile lamp. The device comprises an installation shell, the inner arc surface of the installation shell is connected with an automobile lamp body through bolts, the inner wall of the top and the inner wall of the bottom of the installation shell are connected with two transparent plates through bolts, the transparent plates are parallel to the automobile lamp body, and a cavity is formed between the two transparent plates. When a vehicle runs in foggy weather, a second conveying pump conveys yellow liquid in the storage shell into the cavity, the yellow liquid in the cavity dims light emitted by the vehicle lamp body into yellow, the penetrating power in foggy weather is higher, safety is higher, the vehicle lamp body does not need to beadjusted during dimming, in the driving process, a first conveying pump pumps negative pressure to the top of the lifting plate, liquid circularly flows in the cavity and the storage shell in cooperation with the second conveying pump, and it is guaranteed that the color of the liquid is uniform and dimming is uniform.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, in particular to a dimming device for automobile lamps. Background technique [0002] Car lights, also known as car headlights and car LED daytime running lights, as the eyes of a car, are not only related to the external image of a car owner, but also closely related to driving at night or in bad weather. Aesthetics and lighting effect choose to refit the car headlights into xenon headlights. The light of xenon headlights is cool white light, which has poor penetrating power in foggy weather and poor lighting effects. It is necessary to switch to fog lights with yellow light. Dimming is inconvenient and the brightness of the fog lights is not enough. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a dimming device for automobile lamps. [0004] In order to achieve the above object, the present inventi...
