Abstract

During an SOL collision or a side collision, the load transmission efficiency between the front end of the side sill and the side sill disposed on the opposite side in the vehicle width direction relative to the side sill is improved. A pair of left and right inclined beams (20, 31, 32) are disposed on the upper or lower portion of the floor (2). A pair of slanted beams (20, 31, 32) connect the front part of the side beam (3) extending in the vehicle front-rear direction on the outside of the vehicle body in the vehicle width direction and the hinge pillar (4) extending upward from the front position. ) near the joint site CFr, CF1, and the side beam (3) on the opposite side of the joint site in the vehicle width direction and the center pillar (5) extending upward from the middle position of the side beam (3) in the front and rear direction of the vehicle body CR1 and CRr are connected near the binding site.

Description

technical field [0001] The present invention relates to an underbody structure of a vehicle. The underbody structure of a vehicle includes: left and right side sills extending along the vehicle front-rear direction outside the vehicle body in the vehicle width direction; The central pillar extends upward from the respective middle positions of the left and right side beams in the front-rear direction of the vehicle body; the floor connects the left and right side beams; and the floor tunnel bulges upward at the center of the floor. Background technique [0002] As the lower body structure of a conventional vehicle, in order to ensure the safety performance of the offset collision, for example, the lower body structure of the vehicle of Patent Document 1 and 2 is proposed, and in order to ensure the safety performance of the side collision, for example, the vehicle of the Patent Document 1 is proposed. Underbody construction. [0003] However, in recent years, not only the f...
