Abstract:
1. A vehicle body lower structure comprising: a side sill disposed on an end of a vehicle body in a vehicle width direction so as to extend along the length of the vehicle body, the side sill including a crush area and a bulkhead, the crush area being crushable under a collision load caused by collision with a vehicle in order to absorb the collision load, the bulkhead being disposed on the rear of the crush area inside the side sill; and a reinforcing frame attached to a side surface of the side sill facing a vehicle interior, a first end of the reinforcing frame being joined to the side surface of the side sill facing the vehicle interior, and where the bulk head is disposed, such that the reinforcing frame extends rearwardly and inwardly in the vehicle width direction, a second end of the reinforcing being joined to a floor frame, wherein the side sill includes a side sill inner disposed inside the vehicle body and a side sill outer disposed on the outside of the vehicle body such that the side sill inner and the side sill outer are joined to each other, the side sill inner extends along longitudinal direction of the vehicle body and includes a substantially angular U shape in cross section comprising an upper inner surface, a side inner surface, and a lower inner surface, the upper inner surface, the side inner surface, and the lower inner surface defining a space within the side sill, wherein the reinforcing frame includes an edge line extending along a longitudinal direction of the reinforcing frame, the bulkhead is disposed on an extension of the edge line of the reinforcing frame in plan view, and includes a separating portion and a flange, wherein the separating portion extends in a direction perpendicular to the longitudinal direction of the side sill inner and partitions the space inside the side sill inner into front part and rear part, and wherein the flange is disposed at an edge of the separating portion to form a substantially L shape in cross section together with the separating portion and is joined to the upper inner surface, the side inner surface, and the lower inner surface.
