The gap adjustment part is set to adjust the gap between the tail lamp body 1, the profiling tool 2 and the side wall, so as to absorb the manufacturing and assembly errors of the vehicle body, ensure the matching and connection requirements of the tail lamp body 1 and the appearance parts such as the tail wing and the tailgate switch trim plate, and avoid the risk of lamp cracking caused by stress concentration in the lamp due to forced tightening.

[0048] As shown in Figure 2 , Figure 4 and Figure 5 , in some embodiments, the gap adjustment part includes a plurality of first adjustment assemblies 3, and the plurality of first adjustment assemblies 3 are located at one end of the tail lamp body 1 away from the profiling tool 2. The first adjustment assembly 3 includes a first adjusting nut, a first fixed nut 31 and a first bolt 32. The first adjusting nut includes a fixed part 33 and a rotating part 34, and the fixed part 33 is arranged on the vehicle body or the tail lamp body 1. The rotating part 34 is threadedly connected with the fixed part 33.

[0064] In the present embodiment, by setting the first adjusting assembly 3, the second adjusting assembly 5 and the third adjusting assembly 6, more than 95% of the cumulative tolerance of the vehicle body manufacturing and parts is absorbed. Since the sports car body framework is more than 95% of the aluminum body, the overall precision is not very stable. The automobile tail lamp mounting structure can absorb the manufacturing error of the vehicle body. The first adjusting assembly 3, the second adjusting assembly 5 and the third adjusting assembly 6 can absorb more than ±3mm of the manufacturing deviation of the vehicle body in the height, length and width directions of the vehicle body.
