Reinforcement of the rear body structure at the rear of the vehicle

Abstract

The invention provides a rear body structure for a passenger vehicle, comprising: a rear longitudinal beam (20); a rear floor (30), fixedly connected to the inner side of the rear longitudinal beam (20); a door sill connecting plate (40) , is fixedly connected with the rear longitudinal beam (20), and extends along the longitudinal direction of the vehicle; the reinforcement member (10), the reinforcement member (10) is fixedly connected with the rear floor (30) and the rear longitudinal beam (20), and the reinforcement member (10) The front end along the longitudinal direction of the vehicle is fixedly connected with the door sill connecting plate (40). The rear body structure of the reinforced vehicle rear part of the present invention can improve the structural bearing capacity of the rear part of the vehicle when the vehicle is subjected to a rear-end collision, fully ensure the living space of the rear passengers in an accident, and effectively improve the safety of the vehicle during a rear-end collision .

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...
