Automobile lamp mounting foot structure

Abstract

The invention aims to provide an automobile lamp mounting foot structure capable of ensuring the clearance and the surface difference between a lamp and an automobile body metal plate as well as between the lamp and peripheral fitting parts. The automobile lamp mounting foot structure comprises a lamp shell, mounting feet are arranged at the connecting position of the lamp shell and the automobile body metal plate, and the mounting feet are detachably connected with the lamp shell. Threaded holes are formed in the mounting feet, and bolts penetrate through the threaded holes to fixedly connect the mounting feet with the automobile body metal plate. According to the scheme, the mounting feet and the lamp shell are manufactured into separated parts, injection molding is independently carried out, the process is simple, the deformation of the two parts is small, then the matching gap and surface difference between the lamp and the automobile body metal plate and between the lamp and peripheral matching parts are guaranteed, and even if the deformation of the lamp shell is large, the lamp shell can be conveniently assembled and disassembled by adjusting the mounting feet, and adjustment, installation and matching are achieved under the condition that the shell is not changed.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, in particular to a mounting foot structure for automobile lamps. Background technique [0002] Because of its practicality and aesthetics, car lights are becoming more and more important in the car body. In order to ensure the firm and reliable installation of car lights, mounting feet are usually provided on the car light housing, and the mounting feet correspond to the car body. position installed together. Under normal circumstances, the mounting feet of the lamps are directly injection molded on the lamp shell, and the positioning point with the body fender is often designed on the farthest mounting feet closest to the sheet metal. However, due to the large size of the shell, the mounting feet It is also distributed at the farthest end of the shell, and the shell is a thin-walled part. Adding glass fiber to increase the material strength will make the shell injection deformation lar...

Problems solved by technology

Under normal circumstances, the mounting feet of the lamps are directly injection molded on the lamp shell, and the positioning point with the body fender is often designed on the farthest mounting feet closest to the sheet metal. However, due to the large size of the shell, the mounting feet It is also distributed at the farthest end of the shell, and the shell is a thin-walled part. Adding glass fiber to increase the material strength will make the shell injection deformation larger, resulting in a gap between the lamp and the body sheet metal and surrounding fittings. The surface difference cannot meet the design requirements, affect the appearance quality of the vehicle, and even cause the mounting holes and positioning points to deviate, resulting in failure to install

Based on this situation, engineers can only use other alternative solutions, such as forcing the positioning point on the remote mounting foot as the reference point, and modifying the other parts by matching and verifying the deviation between other parts of the lamp and the mounting point. The position and installation point, this kind of headache and doctor’s foot method will make the matching difficult, the adjustment cycle will be long, and even some points cannot be adjusted due to the large amount of adjustment.
