Document Type and Number:
WIPO Patent Application WO/2023/233930
Kind Code:
A1
Abstract:
A vehicle body lateral section structure 1 according to the present invention comprises: a side sill 3 formed by joining a side sill inner 3a and a side sill outer 3b; a battery pack 5 which is disposed on the interior side of the side sill 3 in the vehicle width direction; and a floor cross member 7 extending in the vehicle width direction. The floor cross member 7, which is made of a metal plate having a tensile strength on the order of 1180 MPa or more, has an end portion 7a disposed to cover an upper surface 3a2 of the side sill inner 3a without abutting on a side surface 3a1 thereof, and extends to, and abuts on, a joint surface portion 3d at an upper end portion 3c of the side sill inner 3a and the side sill outer 3b. In the event of a side collision, after the side sill outer 3b is deformed and crushed, the load input to the side sill 3 is transmitted to the floor cross member 7 so as to reduce the load transmitted to the battery pack 5.
