VEHICLE SIDE PORTION STRUCTURE

摘要

The outer R/F 28 is structured by a member whose strength is higher than and whose ductility is lower than those of the pillar inner panel 26 and the pillar outer panel 24, and has a vertical wall portion 28B that is disposed at a front side in a vehicle longitudinal direction and a vertical wall portion 28C that is disposed at a rear side. Further, a through-hole 32 is formed in the outer R/F 28 at a position that is further toward a vehicle vertical direction lower side than a beltline B and that overlaps a neutral plane M in a planar cross-section that includes the vertical wall portion 28B and the vertical wall portion 28C. The outer R/F 28 is joined to the pillar outer panel 24 at an interior of the closed cross-section, and reinforces the pillar outer panel 24.

主权项

1. A vehicle side portion structure comprising:
a pillar at which a closed cross-section is formed by a pillar inner and a pillar outer that are structured by ordinary steel plates that are each ductile; and a reinforcing member that is structured by a member having a strength that is higher than and a ductility is lower than a strength and ductility of each of the pillar inner and the pillar outer, and that has a front wall disposed at a front side in a vehicle longitudinal direction and a rear wall disposed at a rear side in the vehicle longitudinal direction, and, in at least one of the front wall or the rear wall, a hole portion that passes-through the reinforcing member in the vehicle longitudinal direction being formed at a position that is further toward a lower side in a vehicle vertical direction than a beltline of a vehicle and that overlaps a neutral plane that runs along the vehicle longitudinal direction in a planar cross-section that includes the front wall and the rear wall, and the reinforcing member being joined to the pillar outer at an interior of the closed cross-section and reinforcing the pillar outer.
