Problems solved by technology

There are some following defects in this fixing method: 1, the double-sided adhesive sticking process is not convenient, sometimes it will affect the next assembly process; 2, the sticking is not firm, especially in cold weather or when the temperature is low 3. After the desiccant works for a certain period of time, due to the adsorption of a large amount of water, it loses the drying effect and cannot be replaced

Abstract

The invention discloses a fixing structure of drying agents for an automobile lamp. The fixing structure comprises a rear cover and a pressing ring, a storage groove used for storing the drying agents is formed in the rear cover, the pressing ring is fixed on the rear cover to seal the drying agents in the storage groove, and a plurality of vent holes are formed in the pressing ring. The pressing ring is used for fixing the drying agents in the rear cover, the structure is convenient to mount, a worker can mount the structure as an accessory, the drying agents are firmly fixed and not prone to falling after assembling, the fogging problem of the automobile lamp can be effectively solved, and the drying agents are convenient to replace after moisture saturation inside the drying agents.

Description

technical field [0001] The invention relates to a desiccant fixing structure for automobile lamps, in particular to a desiccant fixing structure for combined headlights. Background technique [0002] The water vapor in the automotive lamps forms a visible film or bead condensation phenomenon on some parts of the surface of the lamp due to the temperature difference; this phenomenon is a normal natural phenomenon and can disappear within the specified environment and time. [0003] Combination headlamps will fog up under certain usage conditions, and now many lighting manufacturers are working on research to solve the phenomenon of lamp fogging. The prior art is to place a desiccant in the lamp, which is beneficial for the desiccant to absorb the moisture in the lamp and solve the fogging phenomenon. A common method of fixing the desiccant is to use double-sided tape to fix the small package of desiccant inside the lamp. There are some following defects in this fixing metho...
