Rear side outer plate welding assembly

Abstract

The invention discloses a rear side outer plate welding assembly which comprises a rear side inner plate assembly, a rear wheel cover inner plate welding piece, a rear wheel cover outer plate welding piece and a rear wheel cover outer plate support plate. The rear wheel cover inner plate welding piece comprises a rear wheel cover inner plate and a front protection plate. The rear wheel cover outer plate welding piece comprises a rear wheel cover outer plate. The rear side inner plate assembly comprises a rear side outer plate, an upper side beam inner plate, a rear side inner plate, a C column reinforcing plate and a D column upper end connector. The upper side beam inner plate is welded with the rear side outer plate, the upper side beam inner plate, the C column reinforcing plate and the rear side outer plate are welded, the rear side inner plate, the C column reinforcing plate and the rear side outer plate are welded, the upper side beam inner plate, the rear side inner plate, the C column reinforcing plate and the rear side outer plate are welded, and the upper side beam inner plate, the rear side inner plate and the C column reinforcing plate are fixedly connected. Components of the rear side outer plate welding assembly are welded independently or connected to be assembled, assembly is convenient, a welding process is better, and the middle door frame rigidity can be effectively improved.

Description

technical field [0001] The invention relates to a welded assembly, in particular to a rear side wall outer plate welded assembly of a vehicle body. Background technique [0002] The welded part of the rear side wall inner panel is a part with a relatively large coverage in the body structure. The main parts of the structure include the rear side wall inner panel, the C-pillar reinforcement plate and the D-pillar reinforcement plate, which cover the upper / lower end joints of the C-pillar and the D-pillar. The upper joint makes a significant contribution to the performance of the entire body-in-white, and its structure determines the difficulty of the body assembly process. The traditional rear side panel inner panel weldment only includes the rear side panel inner panel and local reinforcement plates, and the rear wheelhouse outer panel weldment is welded on the inner panel platform of the factory, and then along with the side panel assembly in the final assembly and rear Wh...

AI Technical Summary

Problems solved by technology

The traditional rear side panel inner panel weldment only includes the rear side panel inner panel and local reinforcement plates, and the rear wheelhouse outer panel weldment is welded on the inner panel platform of the factory, and then along with the side panel assembly in the final assembly and rear Wheelhouse inner plate welding, such as figure 1 As shown, its main features are that the structure of the upper end of the C-pillar is too simple and the stress value is large; the welding process of the lower end of the C-pillar is poor, the connection strength is not enough, and the stress value is large; Edge alignment, poor welding process, relatively large process hole, serious stress concentration
