Problems solved by technology

[0007] However, when the mounted battery is a large battery or the like and the battery frame extending in the front-rear direction of the vehicle body is installed on the outer side in the vehicle width direction than the rear sub-frame, if the vehicle body front side of the rear sub-frame is connected to the If the connecting portion of the battery frame is provided so as to extend obliquely in a substantially straight line toward the front side of the vehicle body and further outward in the vehicle width direction, there is a possibility that the load input to the rear subframe may cause the The joint is deformed so that the load cannot be transmitted to the battery rack

Abstract

The rear body structure of the vehicle includes: a longitudinal beam; a subframe disposed below the longitudinal beam and extending in the front-rear direction of the vehicle body; It is offset toward the outer side in the vehicle width direction with respect to the sub-frame and extends in the front-rear direction of the vehicle body. The frame member includes a longitudinal beam that is offset to the outside in the vehicle width direction relative to the sub-frame and extends in the front-rear direction of the vehicle body, and a transverse beam that extends from the longitudinal beam to the inside in the vehicle width direction. The sub-frame is provided with a connecting portion connected to the frame member, and the connecting portion includes an inclined portion extending obliquely toward the center side in the front-rear direction of the vehicle body and being located outward in the vehicle width direction, and the widening portion. Facing the longitudinal beam, the widened portion expands inward from the inclined portion in the vehicle width direction to a position where the widened portion linearly extends in the front-rear direction of the vehicle body and faces the cross beam.

Description

technical field [0001] The present invention relates to a rear body structure of a vehicle, and more particularly to a rear body structure of a vehicle including a side member and a subframe disposed below the side member. Background technique [0002] Vehicles such as automobiles are known to have a structure in which a rear subframe for supporting an engine, a transmission, and the like is provided at the rear of the vehicle body and below a rear side member extending in the front-rear direction of the vehicle body, and the rear subframe is connected to rear stringer. [0003] For example, Patent Document 1 discloses a structure in which a rear subframe is provided below a rear side member, and the rear subframe is connected to the rear side member. For example, Patent Document 2 discloses a structure in which a rear subframe for mounting an engine and a rear subframe for mounting a transmission are provided under the rear of the vehicle body, the rear subframe for mounti...
