Abstract
Official abstract text for this publication.
A vehicle substructure is capable of efficiently transmitting a load inputted from a front subframe or a front suspension mechanism. The vehicle substructure includes a battery case having a battery housed therein, wherein the battery case includes a bottomed case pan having an opening at a top thereof, and a case cover to close the opening of the case pan, wherein the battery caser is partly formed of a cast member which is arranged at a front end of the case cover and coupled to a rear end of the front subframe.
First claim
Opening claim text (preview).
What is claimed is: 1 . A vehicle substructure comprising a battery case having a battery housed therein, wherein the battery case includes a bottomed case pan having an opening at a top thereof, and a case cover to close the opening of the case pan, wherein the battery case is partly formed of a cast member which is arranged at a front end of the case cover and coupled to a rear end of a front subframe. 2 . The vehicle substructure as claimed in claim 1 , wherein the cast member protrudes frontward to have a pair of protrusions to be coupled to a front suspension mechanism. 3 . The vehicle substructure as claimed in claim 2 , wherein the cast member has a skew portion extending outward in a vehicle width direction and rearward in the vehicle front-rear direction from an outer end in the vehicle width direction of a front edge of the protrusion. 4 . The vehicle substructure as claimed in claim 1 , wherein the battery case is coupled at both ends in the vehicle width direction thereof to a pair of right and left side sills, respectively, and the cast member extends in the vehicle width direction across both ends in the vehicle width direction of the battery case. 5 . The vehicle substructure as claimed in claim 1 , wherein the case pan is provided at a bottom thereof with reinforcing members cross-sectionally in a hat shape as viewed from the front and extending in the vehicle front-rear direction. 6 . The vehicle substructure as claimed in claim 1 , wherein the case cover has, in an up-down direction, a top plate located at a top thereof, a bottom plate located at a bottom thereof, and partitions disposed between the top plate and the bottom plate to couple the top plate with the bottom plate. 7 . The vehicle substructure as claimed in claim 6 , wherein the case cover has larger thicknesses at a front end and a rear end of the top plate and bottom plate than a thickness at a center in the vehicle front-rear direction thereof.
