car body structure

Abstract

The invention provides an automobile body structure. At a lower part joint of the front part of a bottom plate (12) with a lower instrument board (13), a lower surface of the channel part reinforcing frame (16) and a lower surface of a bottom plate (12) under a chassis (17) are connected through a connecting piece (22), in a space enclosed by a side wall (30a) of an upheaval part (30), an upper wall (30b) of the upheaval part, the channel part reinforcing frame (16) and the connecting piece (22), a linear component (31) extending towards an engine chamber (13) in front of the lower instrument board (13) is configured, thus configuration space of the linear component (31) is easy to guarantee, and the degree of freedom of design is improved. Thus, under the condition of not reducing automobile body rigidity, a linear component such as a wiring harness or fuel piping is guided to the engine chamber from the lower surface of the bottom plate.

Description

technical field [0001] The present invention relates to an automobile body structure, in which a channel part protruding upward and extending in the front-rear direction is formed in the center part of the vehicle width direction of the floor, and on the upper surface of the floor plate, on the outside of the vehicle width direction of the channel part A bottom frame extending in the front-rear direction is provided, and a raised portion is formed on the bottom plate at a position between the bottom frame and the channel portion, and the raised portion has a side wall and an upper wall and is formed in a manner of raising a certain height. , on the lower surface of the upper wall of the raised portion along the lower end of the channel portion, a channel portion reinforcement frame extending in the front-rear direction is provided. Background technique [0002] Patent Document 1 below discloses an automobile body structure in which a wiring harness for connecting a battery a...

Problems solved by technology

[0006] However, in the vehicle body structure disclosed in Patent Document 1, since the wire harness is arranged inside the floor, in a vehicle in which the drive shaft is arranged inside the floor, the wire harness interferes with the drive shaft, so it is difficult to adopt such a structure.

[0007] In addition, in the automobile body structure disclosed in Patent Document 2, since an opening is formed in the frame cross member through which the guide member penetrates, there may be a problem that the strength of the cross member as a reinforcing member may be lowered due to the opening.
