Abstract

The invention provides an automobile body rear assembly and an automobile, and relates to the technical field of automobiles. The vehicle body rear assembly comprises a C column assembly and a D column assembly, the C column assembly comprises a door frame assembly, the upper end of the door frame assembly is connected with the upper end of the D column assembly in a fastened mode, and a C column force guiding inner cavity used for enabling acting force on the door frame assembly to be transmitted in the trend of the door frame assembly is formed in the door frame assembly. A D-column force guiding inner cavity used for enabling acting force on the D-column assembly to be transmitted in the trend of the D-column assembly is formed in the D-column assembly, and the C-column force guiding inner cavity and the D-column force guiding inner cavity are isolated from each other or the C-column force guiding inner cavity and the D-column force guiding inner cavity are communicated only through the upper ends of the C-column force guiding inner cavity and the D-column force guiding inner cavity. According to the automobile body rear assembly and the automobile, the efficiency of dispersing acting force borne by the C-column assembly and the D-column assembly to all positions of the automobile body is high, the acting force borne by the C-column assembly and the D-column assembly is not prone to detention, and the torsional rigidity and the torsional mode of the automobile body rear structure are improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a rear body assembly and an automobile. Background technique [0002] As a common means of transportation, the road noise performance of automobiles during driving affects the comfort of drivers and passengers. The torsional stiffness and torsional mode of the rear body structure of the car have a great influence on the road noise performance of the car. [0003] In some related technologies, the rear body assembly of an automobile includes a C-pillar assembly and a D-pillar assembly. The C-pillar assembly includes a door frame section and a door frame middle connecting section formed by bifurcating in the middle of the door frame section toward the D-pillar assembly. The door frame section The upper end of the door frame is tightly connected to the upper end of the D-pillar assembly, the front end of the door frame middle connecting section is fastened to the middle of the ...
