Problems solved by technology

However, when the car lights are working, a large amount of heat will be generated after the light source is lit to form water vapor, and the water vapor in the air in the lamp body will condense on the inner surface of the lens cover of the car lamp after being cooled, especially for headlights. , due to the existence of the fogging phenomenon, the fog beads formed by the fogging are one of the main sources of water accumulation in the headlights, and the water accumulation in the headlights will become fogging again, which seriously threatens the use of headlight bulbs. Life and the safety of the circuit inside the lamp not only affect the appearance of the lamp, but also greatly reduce the lighting effect of the lamp, affecting driving safety
In addition, the long-term condensation of water vapor in the lamp on the surface of the lamp reflector and lens will cause the lamp material to corrode, accelerate the aging of the material, deform the lamp material, and destroy the optical control effect. Effective handling will affect the service life and performance of surrounding components
Therefore, at present, automobile lamps, especially front lamps, adopt different heat dissipation methods, but there are problems of complex heat dissipation structure and high cost.
But so far, lamp fogging is still a major problem affecting the quality of lamps

Abstract

The invention relates to a moisture absorption structure for an automobile headlamp. The moisture absorption structure comprises a lamp body, wherein a rear cover and a cover plate are mounted at a rear cover hole of the lamp body; the rear cover comprises a connecting ring made of rubber and a cover body with a ring edge, and the cover body is made of plastic; an annular convex rib raised on the upper end surface of the ring edge of the cover body is pressed into an annular groove of the connecting ring and is fixedly connected with the connecting ring, the connecting ring is connected with the rear cover hole in the lamp body in a sealing manner, and at least two bumps are arranged in the cover body; the cover plate is cylindrical, and more than two notches in the cover plate are buckled with the bumps on the cover plate; a drying agent is placed in a cavity between the cover plate and the cover body, and discontinuous vent groove holes are formed in the cover body. The moisture absorption structure is simple in structure and low in cost, cannot affect the illumination function of the automobile headlamp, and can also improve the fogging phenomenon in the automobile headlamp.

Description

technical field [0001] The invention relates to a hygroscopic structure used for automobile headlights, belonging to the technical field of automobile headlights. Background technique [0002] In the modern car lamp manufacturing industry, the design, manufacture and process are becoming more and more complicated, and a large number of advanced technologies are used to improve the quality of the car lights. However, when the car lights are working, a large amount of heat will be generated after the light source is lit to form water vapor, and the water vapor in the air in the lamp body will condense on the inner surface of the lens cover of the car lamp after being cooled, especially for headlights. , due to the existence of the fogging phenomenon, the fog beads formed by the fogging are one of the main sources of water accumulation in the headlights, and the water accumulation in the headlights will become fogging again, which seriously threatens the use of headlight bulbs....
