Abstract

A vehicle lower structure includes a front side frame coupled to a floor frame, and an outrigger extending outward in the vehicle-width direction from the front side frame to a side sill. A reinforcing member extends obliquely rearward in the vehicle-width direction from the side sill to the front side frame. The reinforcing member has a curved portion curved upward in the middle thereof and is formed substantially in a V shape.

First claim

What is claimed is:

1 . A vehicle lower structure comprising:
a front side frame; a floor frame, wherein a front end of the floor frame is joined to a rear end of the front side frame; a side sill disposed on an outer side of the floor frame in a vehicle-width direction; an outrigger extending outward in the vehicle-width direction from the front side frame to a front end of the side sill; a reinforcing member extending obliquely rearward and inward in the vehicle-width direction from a junction area between the outrigger and the side sill to the front side frame, wherein the reinforcing member includes a bent portion bent upward or downward at an intermediate position thereof.

2 . The vehicle lower structure according to claim 1 , further comprising:
a front assembly including the front side frame and the outrigger; and a floor assembly including the side sill, the floor frame, and a floor panel supported by the side sill and the floor frame, wherein the reinforcing member is joined, to upper or lower surfaces of the front side frame and the outrigger of the front assembly and is joined to upper or lower surfaces of the side sill and the floor panel.

3 . The vehicle lower structure according to claim 1 ,
wherein the reinforcing member has a leading edge located toward the front of a vehicle and a trailing edge located toward the rear of the vehicle, and wherein the leading edge of the reinforcing member is inclined, toward the front of the vehicle to a greater degree than that of the trailing edge.

4 . The vehicle lower structure according to claim 2 ,
wherein an outer end of the reinforcing, member is located, in the vicinity of a junction area between, an outer end of the outrigger arid the floor panel, and wherein the reinforcing member includes an opening in the vicinity of the outer end of the reinforcing member.

5 . The vehicle lower structure according to claim 2 ,
wherein the side sill includes a stiffener for reinforcement inside thereof, and wherein the reinforcing member has a projecting portion projecting to an area of the side sill located at the rear of the outrigger.

6 . The vehicle lower structure according to claim 2 ,
wherein the floor panel includes a planar flat portion, a slanted portion located adjacent to at least one of front and rear ends of the flat portion, a folded portion provided at the boundary between the flat portion and the slanted portion, and a seat portion that projects from the folded portion and to which the reinforcing member is joined.

7 . The vehicle lower structure according to claim 2 ,
wherein the reinforcing member is disposed under a lower surface of the floor panel, the bent portion bends upward and a pipe is disposed in the bent portion.

8 . The vehicle lower structure according to claim 1 , wherein the bent portion has a substantially V shape.

9 . The vehicle lower structure according to claim 5 , wherein the projecting portion, the side sill, and the stiffener are overlapped and joined to one another.

10 . The vehicle lower structure according to claim 3 ,
wherein the leading edge and the trailing edge of the reinforcing member are connected to a floor panel.

11 . A vehicle comprising the vehicle lower structure according to claim 1 .
