Rear automobile body structure for reinforcing rear of automobile

Abstract

The invention provides a rear automobile body structure used for a passenger automobile. The rear automobile body structure comprises a rear longitudinal beam (20), a rear floor (30), a doorsill connecting plate (40) and a reinforcing component (10), wherein the rear floor (30) is fixedly connected to the inner side of the rear longitudinal beam (20); the doorsill connecting plate (40) is fixedly connected with the rear longitudinal beam (20) and extends in the longitudinal direction of the automobile; the reinforcing component (10) is fixedly connected with the rear floor (30) and the rear longitudinal beam (20) and fixedly connected with the doorsill connecting plate (40) along the front end of the automobile in the longitudinal direction. According to the rear automobile body structure for reinforcing the rear of the automobile, the structural bearing capacity of the rear of the automobile can be improved when the automobile is impacted in rear-end collision, the living space for passengers in the rear row is fully guaranteed in the accident, and the safety of the automobile in rear-end collision can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of automobile structures, in particular to a rear body structure for reinforcing the rear of a vehicle. Background technique [0002] At present, the frontal and side collision safety performance of vehicles has been paid enough attention in the vehicle development process, and most passenger cars can provide effective protection for the occupants in the event of frontal collision and side collision accidents. However, the safety performance of the rear of the car is low. When the vehicle is subjected to a rear-end collision, the structural bearing capacity of the rear of the vehicle is insufficient, which will cause the living space of the rear passengers to become smaller during the collision, and the door cannot be opened after the accident. Contents of the invention [0003] One object of the present invention is to provide a rear body structure that strengthens the rear of the vehicle to improve the s...
