Title:
STRUCTURE FOR LOWER PORTION OF VEHICLE
Document Type and Number:
WIPO Patent Application WO/2013/024528
Kind Code:
A1
Abstract:
Obtained is a structure for the lower portion of a vehicle, the structure being configured so that, without particularly increasing the mechanical strength of the connection portions between a brace and floor frames, the structure can maintain the connection between the brace and the floor frames against a load transmitted from the front side through the brace.
A brace (60) is provided with a front connection section (62) and a rear connection section (92). The front connection section (62) and the rear connection section (92) are connected to each other by a load transmission section (100) which is substantially M-shaped in a plan view. Also, the rear connection section (92) and the outer load transmission sections (102) of the load transmission section (100) are connected to each other at positions closer to the center in the left-right direction than connection portions of the rear connection section (92), the connection portions being those at which the rear connection section (92) is connected to the floor frames (30). As a result of the configuration, a load which is transmitted to the rear connection section (92) tries to deform the rear connection section (92) about the rear ends of the outer load transmission sections (102), and the load becomes less likely to break the connection portions between the rear connection section (92) and the floor frames (30).
