Problems solved by technology

However, when a larger impact (load) is input when the rear surface is collided, the large impact (load) is transmitted from the impact absorbing member to the rear cross member and the bulkhead, and the rear cross member at the rear opening of the vehicle body is deformed
Considering that the rear beam at the rear opening of the vehicle body needs to be replaced together with the bulkhead, the cost of parts replacement increases

Abstract

This vehicle body rear structure is provided with: a left and right rear-side frame (21) that extend in the front-back direction of the vehicle body (12); and a rear panel assembly (27) that forms a closed-cross-section section (41) extending in the direction of vehicle width intersecting the rear-side frames (21), is provided to the back end (25) of the rear-side frames (21), and configures the bottom of a vehicle body rear opening (37). The rear panel assembly (27) is provided with a bulkhead (45) that is disposed in the closed-cross-section section (41) at the upper surface (43) of the rear-side frames (21), and that partitions the interior of the closed-cross-section section (41) with surfaces oriented in the direction of vehicle width.

Description

technical field [0001] The present invention relates to a vehicle body rear structure in which a rear wall forming a storage compartment of a vehicle is formed in a closed cross-sectional shape. Background technique [0002] A vehicle body rear opening for loading luggage into the storage room is formed at the rear of the vehicle body, and a rear cross member forming a part of the vehicle rear opening is arranged at a low position to facilitate entry and exit of luggage. [0003] In the vehicle body rear portion described above, the rear beam is formed in a closed cross-sectional shape, and left and right ends are joined to a rear frame extending in the front direction. Since the gusset plate is provided on the lower part of the rear cross member lower than the rear frame and the lower surface of the rear frame, and a bulkhead is provided inside the rear cross member, the strength of the rear portion of the vehicle body can be improved (for example, refer to the patent docum...
