Description

Technical Field

[0001] The utility model relates to an automobile tail lamp, in particular to an automobile tail lamp with a thick-walled light-guiding structure for reducing a lighting gap. Background Art

[0002] In order to make the taillights more beautiful and have a better lighting effect, the existing OEMs usually design the taillights as through-type taillights that penetrate the rear of the car. Since the rear of the car is also designed with a tailgate, part of the taillights need to be designed on the tailgate, so that there is an assembly gap for opening and closing the tailgate between the active taillights on the tailgate and the fixed taillights on the rear of the car. At the same time, in the taillights currently using thick-walled light guide structures, in order to establish the mold structure of the decorative ring and the overall strength of the decorative ring, the through hole for installing the thick-walled light guide is opened on the inner side of the decorative ring, so that there is no opening around the through hole, thereby further improving the strength of the decorative ring. The existing automobile taillights further increase the length of the decorative ring outside the through hole on the basis of the original assembly interval between the active taillight and the fixed taillight, so that when the taillight is lit, there is a dark gap between the active taillight and the fixed taillight. When the gap is too large, it affects the functional continuity and the appearance. Utility Model Content
