Car tail lamp strengthening structure capable of preventing car body interference and manufacturing method thereof

Abstract

The invention discloses a car tail lamp strengthening structure capable of preventing car body interference and further discloses a manufacturing method of the car tail lamp strengthening structure capable of preventing car body interference. The car tail lamp strengthening structure comprises a lamp shell and a lampshade. The lamp shell is sleeved with the lampshade. A plurality of positioning grooves are evenly formed in the edges of the two sides of the lamp shell; the groove faces of the positioning grooves are parallel to the mounting face of the lamp shell and connected with the bottom faces of compressible bosses in an attached mode; the top faces of the compressible bosses are parallel to the groove faces of the positioning grooves; and the thickness of each compressed compressibleboss is equal to the minimum clearance between the lampshade and a car body side wall plate. The positioning grooves and the compressible bosses are designed through a CAE analysis method; when the clearance is decreased due to the surface difference, the component error and the mounting deviation between a tail lamp assembly and the car body side wall plate, the compressible bosses replace the lampshade to make contact with the car body side wall plate; and the thickness of each compressible boss compressed to the largest extent is equal to the minimum clearance between the lampshade and thecar body side wall plate, and thus the lampshade and the car body side wall plate do not interfere with each other.

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...

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
