Structure for side portion of vehicle

Abstract

A structure for a side portion of a vehicle has a closed cross-section structure formed by joining together an inner panel on the vehicle interior side and an outer panel on the vehicle exterior side, and also has a side sill as a vehicle body frame member placed at the side portion of the vehicle so as to extend in the front-rear direction of the vehicle. At a portion of an outer wall of the outer panel, there is formed an arch surface projecting outwardly of the vehicle interior with a position near the joined position of a vehicle body center pillar defined as the top of the arch. The outer panel has a flat surface section adjacent to the arch surface and including a rectilinear section extending in the front-rear direction of the vehicle body. The front end of the side sill is connected to a front side frame of the vehicle body. The rear end of the side sill is connected to a rear frame of the vehicle body.

Description

technical field [0001] The present invention relates to vehicle body sides, and more particularly to body side construction around side sills. [0002] This application claims priority based on Japanese Patent Application No. 2007-327232 filed in Japan on December 19, 2007 and Japanese Patent Application No. 2007-331009 filed in Japan on December 21, 2007, and the contents of these applications are incorporated herein . Background technique [0003] The side sills provided on the sides of the vehicle body function as structural members in the front-rear direction of the vehicle body. During a frontal collision of the vehicle body, the side sill resists the collision by receiving part of the load acting from the front in a buckling direction that is advantageous in terms of strength. Therefore, generally, the side sill has a closed cross-sectional structure extending in the front-rear direction of the vehicle body which is advantageous in terms of strength and rigidity, and...

AI Technical Summary

Problems solved by technology

[0006] However, with the prior art described above, the closure body reinforcement is integrally formed in an arched shape

Therefore, for example, in the state where the centers of the vehicle body are offset from each other, when a so-called offset collision occurs in a frontal collision, the load in the front-rear direction concentrates on the closing body reinforcement on one side, and the arch-shaped closing body reinforcement There is a problem of easy bending on the parts

[0007] In this regard, countermeasures such as installing additional reinforcement members or increasing the plate thickness of the closure body reinforcement were considered, but the weight of the vehicle body increased accordingly, and as a result, there was a problem of increased fuel consumption.
