Rear connecting assembly of rear wheel cover

Abstract

The invention discloses a rear connecting assembly of a rear wheel cover. The rear connecting assembly comprises an upper connecting plate fixed to a side body inner plate, and a lower connecting plate fixed to a rear floor and a side body outer plate. A gap is reserved between the lower end of the upper connecting plate and the lower connecting plate, the upper portion of the upper connecting plate is fixed to the lower portion of the side body inner plate, the inner side of the upper portion of the lower connecting plate is fixed to the outer side of the end of the rear floor, the outer side of the lower portion of the lower connecting plate is fixed to the inner side of the lower portion of the side body outer plate, a side body cavity is formed among the side body inner plate, the upper connecting plate, the lower connecting plate and the side body outer plate, and the upper connecting plate and an outer plate of the rear wheel cover are in lap joint. The rear connecting assembly of the rear wheel cover is simple in structure and ensures that the torsional rigidity of the tail of a vehicle body is achieved; meanwhile, in the rear area of the rear wheel cover, the electric-arc welding technology does not need to be adopted for a side body sub-assembly and the rear floor, the production efficiency is effectively improved, the potential safety hazard of workers is eliminated, and pollution is avoided.

Description

technical field [0001] The invention relates to a connecting assembly, in particular to a rear wheel housing rear connecting assembly. Background technique [0002] In the rear area of ​​the rear wheel house, the side panel subassembly is generally connected to the rear floor 5 through the rear wheel house rear connection plate 20, and the rear wheel house rear connection plate has two functions: [0003] First, before the body is welded, the rear part of the side panel subassembly is pre-assembled in the up and down direction of the vehicle body through pre-installed buckles to avoid sinking and falling of the rear part of the side panel subassembly; [0004] The second is to form a closed side wall cavity 12 with the side wall inner panel 3 and the side wall outer panel 4 to improve the torsional rigidity of the rear of the vehicle body, especially the torsional rigidity of the rear of the vehicle body with large tailgate openings such as vans and SUVs. [0005] The curre...

AI Technical Summary

Problems solved by technology

Due to the blockage of the side wall outer panel 4 and the side wall cavity 12 of the side wall subassembly, the connection between the rear wheelhouse rear connection plate 20 and the side wall inner plate 3 cannot be completed by resistance welding, and an arc welding process must be used inside the car body Welding: 1. Low production efficiency; 2. Unstable weld seam quality; 3. Poor ergonomics, entering the body for arc welding, which poses safety hazards for personnel; 4. Arc welding produces waste gas, pollutes the environment, and poisons the body of operators healthy
