Abstract
Official abstract text for this publication.
A battery pack comprises a lower-stage battery stack and an upper-stage battery stack. The upper-stage battery stack is separated from the lower-stage battery stack in a vehicle height direction. A middle frame that is a reinforcing member is arranged at a height position that matches a height position of a separation space between the upper-stage battery stack and the lower-stage battery stack in terms of a position in the vehicle height direction. Longitudinal frames of the middle frame project outward from the upper-stage battery stack in a vehicle width direction.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle lower structure comprising: a battery pack stored under a floor panel, a lower frame that is a framework member provided on a bottom surface of the battery pack, and having fastening portions formed at both ends that project outward from the battery pack in a vehicle width direction, a pair of side members that are framework members, the side members being provided on both sides of the floor panel in the vehicle width direction and extending in a vehicle front-rear direction, wherein the fastening portions of the lower frame are fastened to the side members, wherein the battery pack comprises a lower-stage battery stack fixed to the lower frame and an upper-stage battery stack mounted in an upper stage of the lower-stage battery stack, the upper-stage battery stack is separated from the lower-stage battery stack in a vehicle height direction, a reinforcing member is arranged at a height position that matches a height position of a separation space between the upper-stage battery stack and the lower-stage battery stack in the vehicle height direction, and the reinforcing member comprises a pair of transverse frames extending in the vehicle width direction and provided in the vehicle front-rear direction, and a pair of longitudinal frames connected to both ends of the pair of transverse frames in the vehicle width direction and extending in the vehicle front-rear direction, and the longitudinal frames project outward from the upper-stage battery stack in the vehicle width direction. 2. The vehicle lower structure according to claim 1 , wherein each longitudinal frame includes an overlap region that is aligned with the side members in terms of a position in the vehicle height direction, and an auxiliary member is provided to further project outward from the overlap region of the longitudinal frame in the vehicle width direction. 3. The vehicle lower structure according to claim 1 , wherein the battery pack comprises a case tray that stores the upper-stage battery stack and the lower-stage battery stack, the upper-stage battery stack is fixed to an upper end of a plate-shaped bracket extending upward from the case tray in the vehicle front-rear direction, and a ridgeline is formed on the bracket across the vehicle front-rear direction. 4. The vehicle lower structure according to claim 2 , wherein the battery pack comprises a case tray that stores the upper-stage battery stack and the lower-stage battery stack, the upper-stage battery stack is fixed to an upper end of a plate-shaped bracket extending upward from the case tray in the vehicle front-rear direction, and a ridgeline is formed on the bracket across the vehicle front-rear direction.
