Abstract
Official abstract text for this publication.
Provided is a vehicle lower-part structure including: a pair of center side members; a main battery that is arranged between the pair of center side members; a support cross member connecting the pair of center side members and supporting a front end of the main battery from below; a pair of support brackets that protrude toward a center in a vehicle width direction from the pair of center side members at positions closer to a rear other end with respect to the support cross member, and support the main battery; and a cable drawn out from the main battery.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle lower-part structure comprising: a pair of center side members extending in a vehicle front-rear direction under a floor of a vehicle; a main battery that is arranged between the pair of center side members; a support cross member extending in a vehicle width direction to connect the pair of center side members and supporting one end of the main battery in the vehicle front-rear direction from below; a pair of support brackets that protrude toward a center in the vehicle width direction from each of the pair of center side members at positions closer to the other end in the vehicle front-rear direction with respect to the support cross member, and support the main battery; and a cable drawn out from the main battery and extending in a direction away from the support cross member. 2. The vehicle lower-part structure according to claim 1 , wherein the pair of support brackets suspend and hold the main battery. 3. The vehicle lower-part structure according to claim 1 , wherein the main battery includes: a main body portion; and projecting portions that project to respective sides in the vehicle width direction from the main body portion and each having an upper surface that is lower than an upper surface of the main body portion, and the pair of support brackets are fastened to the upper surfaces of the projecting portions. 4. The vehicle lower-part structure according to claim 1 , wherein the support brackets have a non-linear cross sectional shape in a plane orthogonal to the vehicle width direction. 5. The vehicle lower-part structure according to claim 1 , further comprising: a first cross member and a second cross member connecting the pair of center side members on respective sides of the main battery in the vehicle front-rear direction; and an on-vehicle device arranged at a corner of an underfloor space surrounded by the pair of center side members, the first cross member, and the second cross member, wherein at least one corner of the main battery is diagonally cut off, and the on-vehicle device is arranged so that at least a part of the on-vehicle device overlaps a corner cut portion of the main battery in the vehicle front-rear direction.
