D-pillar assembly, d-ring assembly and vehicle

Abstract

The application provides a D-column assembly, a D-ring assembly and an automobile. The D-column assembly comprises a D-column inner panel and a D-column reinforcing panel. The D-column inner panel is integrally formed. The D-column reinforcing panel is arranged on the outer side of the D-column inner panel along the extension direction of the D-column inner panel. The D-column reinforcing panel comprises a D-column upper reinforcing panel, a D-column middle reinforcing panel and a D-column lower reinforcing panel which are sequentially connected along the extension direction of the D-column inner panel. The D-column inner panel is integrally formed, and the D-column assembly is formed by cooperating with the sectional reinforcing panel. The D-ring assembly with the D-column assembly has good body modal performance and torsional stiffness performance. Meanwhile, the whole vehicle is light in weight.
