Reinforcing structure for vehicle tail light preventing vehicle body interference and manufacturing method thereof

Abstract

The invention discloses a vehicle tail light reinforcement structure for preventing vehicle body interference, which comprises a lamp housing and a lamp shade. The groove surface of the groove is parallel to the mounting surface of the lamp housing, the groove surface of the positioning groove fits the bottom surface of the compressible boss, the top surface of the compressible boss is parallel to the groove surface of the positioning groove, and the thickness of the compressible boss is compressed is the minimum gap between the light housing and the body side panel. The invention also discloses a manufacturing method of a vehicle tail light reinforcement structure for preventing vehicle body interference. The present invention adopts the positioning groove and the compressible boss designed by the CAE analysis method. When the gap between the taillight assembly and the side panel of the vehicle body becomes small due to surface difference, part error, and installation deviation, the compressible boss can replace the lampshade and the vehicle body. When the side panel is in contact, the thickness when it is compressed to the maximum extent is the minimum gap that should be kept between the lampshade and the body side panel, and the lampshade and the body side panel do not interfere.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a vehicle taillight reinforcement structure for preventing vehicle body interference and a manufacturing method thereof. Background technique [0002] Automobile taillights are usually connected with the back door, rear bumper and body side panel. When industrializing the design of automobile taillights, in order to ensure the perceived quality aesthetics and assembly quality, the visual gap between the passenger car taillights and the body side panel is designed to be small. About 1mm, and the gap between the taillights, the back door and the rear bumper is relatively large. Due to the deviation (±0.7) in the size of the side panels of the body and the deviation (±0.7) in the contour accuracy of the taillight assembly, there will also be a certain installation deviation when the taillight is installed. Therefore, when the taillight assembly is assembled on the bod...

AI Technical Summary

Problems solved by technology

Due to the deviation (±0.7) in the size of the side panels of the body and the deviation (±0.7) in the contour accuracy of the taillight assembly, there will also be a certain installation deviation when the taillight is installed. Therefore, when the taillight assembly is assembled on the body , when the body side panel and tail light fluctuate within the tolerance range, the tail light cover and the body side panel are prone to zero clearance, causing interference between the tail light cover and the body side panel, resulting in abnormal noise under dynamic conditions, and the lamp cover and lamp housing falling off Open and sheet metal paint peeling off and other issues

[0003] At present, most passenger cars in China have the problem of interference due to the small gap between the taillight lampshade and the side panel of the body caused by size deviation, precision deviation, and installation deviation. The industrial debugging process for this problem is cumbersome. Time-consuming, consumable and labor-intensive for model repair and adaptation
