Embodiment Construction

[0066] Below, refer to the attached Figure 1-13 , an example of the vehicle body underbody structure according to the embodiment of the present invention will be described.

[0067] In addition, in the description, the traveling direction of the vehicle is referred to as "front", the backward direction is referred to as "rear", the vertically upward side is referred to as "upper", the vertically downward side is referred to as "down", and the vehicle width direction is referred to as "left". ,"right". Next, the present invention will be described by taking, as an example, a passenger vehicle including a door opening 1 a for a front side door in a vehicle body front portion 1 b of the vehicle body 1 .

[0068]

[0069] like figure 1 As shown, the vehicle only needs to include doors (not shown) movably supported on the left and right vehicle body front parts 1b of the vehicle body 1, a door opening 1a provided with a freely openable and closable door, and a front door formi...

Abstract

The objective of the invention is to provide a vehicle lower-body structure capable for better absorbing offset impact of small area with light weight and excellent production efficiency. The vehicle lower-body structure includes a front pillar, including a front-pillar outer panel and a front-pillar inner panel, and a side sill, including a side-sill outer panel and a side-sill inner panel and joined to a lower portion of the front pillar. The front-pillar outer panel is joined to an outer surface of the side-sill outer panel. The front-pillar inner panel is held between the side-sill outer panel and the side-sill inner panel. The side-sill outer panel and the side-sill inner panel respectively include vertical beads in front of a reinforcement member disposed at a front portion of the side sill and below the front pillar, the vertical beads extending vertically.

Description

technical field [0001] The present invention relates to a vehicle body lower structure, in particular to a vehicle body lower structure with improved collision load absorption performance when small-area offset impacts (Narrow Offset Impacts) occur. The so-called "small-area offset collision" means that the collision object such as the oncoming vehicle (vehicle traveling in the opposite direction) deviates to the right or left side of the front end of the vehicle and collides with the front end of the side member. Background technique [0002] Small-area offset collisions refer to the collisions where a collision object such as an oncoming vehicle collides with the outer side of the front side frame of the vehicle with a small amount of overlap, and is also called "small overlap impacts". In the prior art, there is known an underbody structure in which a collapse area is provided at the front end of a side sill to absorb impact in response to a small-area offset collision (f...
