A rear side wall outer panel welding assembly

Abstract

The invention discloses a rear side wall outer panel welded assembly, which comprises a rear side wall inner panel assembly, a rear wheel house inner panel welded part, a rear wheel house outer plate welded part and a rear wheel house outer plate support plate. Wheelhouse inner panel weldment includes rear wheelhouse inner panel and front fender, rear wheelhouse outer panel weldment includes rear wheelhouse outer panel, rear side panel inner panel assembly includes rear side panel outer panel, upper side sill inner panel , Rear side wall inner panel, C-pillar upper reinforcement plate and D-pillar upper end joint, roof side sill inner panel and rear side wall outer panel welded, roof side sill inner panel, C-pillar upper reinforcement plate and rear side wall outer panel welded, rear side Wall inner panel, C-pillar upper reinforcement panel and rear side panel outer panel are welded, roof side sill inner panel, rear side panel inner panel, C-pillar upper reinforcement panel and rear side panel outer panel are welded, roof side sill inner panel, rear side panel inner The plate is fixedly connected to the reinforcing plate on the C-pillar. The parts of the rear side wall outer plate welding assembly of the present invention are welded or connected separately and then assembled, which is convenient for assembly, makes the welding process more perfect, and can effectively increase the rigidity of the middle door frame.

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 upper reinforcement plate and the D-pillar reinforcement plate, which cover the upper / lower end joints of the C-pillar, the D-pillar The upper end joint of the column makes a significant contribution to the performance of the entire body-in-white, and its structure determines the difficulty of the overall assembly process of the body. 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...

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
