Car body fore part arrangement

Abstract

A front part structure of a vehicle body, to efficiently transmit collision energy applied from the front side of a vehicle body to the whole vehicle body from a dash board. The vehicle body 10 has the front part of the vehicle body partitioned by the dash-board 41 into a front part engine room 42 and a rear part cabin 43, wherein a sub-frame 44 for mounting the engine is installed to the right and left front side frames extending in the front and rear direction of the vehicle body within the engine room. A cross member 21 is disposed between the right and left front side frames at the dashboard, and the extension part 102 is extended backward from the cross member, connecting the front end part 62 of a floor tunnel 15 extending in the front and rear directions of the vehicle body to the rear end part of the extension part.

Description

technical field [0001] The present invention relates to a front structure of a vehicle body, in particular to an improvement technique of an instrument panel part. Background technique [0002] In vehicles such as automobiles, a technique of providing a beam on a dashboard portion is known (for example, refer to Patent Document 1). [0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 10-7022 (Fig. 1-Fig. 3) [0004] Patent Document 1 will be described based on the following drawings. [0005] Fig. 19 is a schematic diagram of a conventional vehicle body structure. Fig. 20 is a sectional view taken along line 20-20 of Fig. 19 . [0006] The existing vehicle body 200 divides the front part of the vehicle body into an engine room 202 and a rear vehicle compartment 203 by using a dashboard 201, and forms a channel part 204 of a recessed portion that penetrates front and rear at the central lower part of the instrument panel 201. Immediately above the porti...

Problems solved by technology

[0009] Therefore, the beam 205 is required to be able to absorb the collision energy and driving vibration from the front of the vehicle body. However, there is a limit to how efficiently the beam 205 can absorb the collision energy or driving vibration, so there is room for improvement.
