Rear connection assembly of a rear wheel housing

Abstract

The invention discloses a rear connection assembly of a rear wheel house, which comprises an upper connection plate fixed to the side wall inner panel and a lower connection plate fixed to the rear floor and the side wall outer panel, the lower end of the upper connection plate is connected to the There is a gap between the lower connecting plates, the upper part of the upper connecting plate is fixed to the lower part of the side wall inner panel, the inner side of the upper part of the lower connecting plate is fixed to the outer side of the end of the rear floor, and the lower connecting plate The outer side of the lower part of the connecting plate is fixed to the inner side of the lower part of the side wall outer panel, and a side wall cavity is formed between the side wall inner panel, upper connecting plate, lower connecting plate and the side wall outer panel, and the upper connecting panel The plate overlaps with the rear wheelhouse outer panel. The rear wheel house rear connection assembly of the present invention has a simple structure. While ensuring the torsional rigidity of the rear part of the vehicle body, the arc welding process is avoided in the rear area of ​​the rear wheel house, the side wall subassembly and the rear floor, and the production efficiency is effectively improved. Eliminate potential safety hazards for personnel and avoid pollution.

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
