Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp installation, in particular to a vehicle lamp rubber groove matching structure. Background Art

[0002] With the rise and breakthrough of new energy and traditional automobile industries in my country, automotive through-type lamps are increasingly used by major automobile companies in the market. As a result, the deformation of individual parts of long through-type lamps during injection molding is large. When assembling parts, the deformation size will not match the design, which also increases the difficulty of matching the through-type lamp with the rubber groove, and the risk of rubber groove failure is also increased.

[0003] At present, common problems of glue lamps in the domestic automotive lighting industry include fogging, water leakage, uneven coverage of the glue layer and poor adhesion. Among them, the probability of water leakage and air leakage caused by the decline in the sealing performance of the glue groove is relatively high. In order not to affect the performance and service life of the lamp, the automotive lamp glue groove is required to cooperate with the structure to connect the lamp housing and the photometric lens. Generally, when designing the glue groove, the maximum outer contour of the photometric lens and the lamp housing is flush. The front and rear limit ribs when assembling the photometric lens and the lamp housing are at the boundary of the lamp housing glue groove. During the pressing process of the adhesive tooling, the deformation of the photometric lens and the lamp housing can easily cause the limit ribs to squeeze out, resulting in limit failure. The photometric lens glue rib will be squeezed to the bottom of the lamp housing glue groove, cutting off the hot melt adhesive. At the same time, the glue sinks and accumulates, and the adhesive area is reduced, which seriously affects the bonding strength and the viscosity of the hot melt adhesive. The strength is greatly reduced, accompanied by adhesive cracking, and problems such as air leakage, water leakage and fogging of the lamp will occur. Utility Model Content
