Title:
VEHICLE BODY STRUCTURE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/225642
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a vehicle body structure for a vehicle 1 with which a front collision load acting on a side sill 5 via a front wheel 2 can be absorbed and the front wheel 2, which has been oriented toward the inside in a vehicle width direction, can be prevented from moving backward. This vehicle body structure for a vehicle 1 comprises: a left-right pair of front wheels 2; and a left-right pair of side sills 5 which form, by means of a side sill outer 52 and a side sill inner 51, a closed cross-section extending in a vehicle front-rear direction. The side sill inner 51 is composed of an inner body 53 that has an open cross-section shape which is opened on the outer side in the vehicle width direction, and an inner front-end part 54 that is connected to the front end of the inner body 53. The side sill outer 52 is composed of an outer body 55 that has an open cross-section shape which is opened on the inner side in the vehicle width direction, and an outer front-end part 56 that is connected to the front end of the outer body 55. The inner body 53, the outer body 55, the inner front-end part 54, and the outer front-end part 56 are configured such that the deformation strength thereof relative to a pressing load from the front of the vehicle decreases in a stepwise manner in the order in which the elements are mentioned above.
