Problems solved by technology

[0005] However, as shown in the above-mentioned publication, the structure in which only shock absorbing members are provided at the front ends of the two side frame portions of the front subframe is very effective when a vehicle collides with a vehicle in a full frontal collision (full lap). When a vehicle collides with a left-right offset state (offset collision), the impact energy cannot be absorbed by the impact absorbing members on both sides, and when it collides with a pillar or other small-width object (pillar collision), depending on the collision position, the vehicle passes through the impact energy. Absorbing members may not absorb impact energy at all

Embodiment Construction

[0054] Hereinafter, embodiments of the present invention will be described with reference to the above-mentioned drawings. The vehicle frame and beam in each embodiment are made of steel unless otherwise specified in advance.

[0055] Such as figure 1 and figure 2 As shown, the vehicle frame 1 includes: a pair of left and right front side frames 2, 2 extending along the front and rear direction of the vehicle; Upwardly bent portions 4, 4 inclined rearward and downward are formed on the rear portions of the front side frames 2, 2, whereby the front ends of the front side frames 2, 2 are positioned higher than the bottom frame 3 by a certain degree.

[0056] Near the middle of the front side frames 2, 2 are formed adjacent to the outside of the vehicle, wheel housings 5, 5 for accommodating unillustrated front wheels, and near the center are formed upside-down shock absorbers for accommodating and supporting the front wheels. suspension tower) 6,6.

Abstract

An automobile front-part structure is provided in which an impact-absorbing member can absorb the impact energy that is given by a bump, whatever bump it is, such as an offset collision and a pole bump. This automobile front-part structure including: a pair of vehicle-body frames which extends in the front-and-rear directions along both sides of a vehicle, and whose front-end parts extend up to the front part of an automobile; and a front sub-frame which is supported with the vehicle-body frames in the front part of the vehicle, and is disposed below the vehicle-body frames, in which the front sub-frame includes: a front sub-frame main-body which has, a pair of right and left side frames which extends in the front-and-rear directions of the vehicle, and a cross member which is formed by a reinforcement and bridges the front parts of the side frames; a pair of right and left impact absorbing members which is formed by a crush pipe, is disposed at the front-end parts of the side frames in the front sub-frame main-body and absorbs impact energy from ahead; and a reinforcement which bridges the front ends of both impact absorbing members.

Description

technical field [0001] The present invention relates to a technique of providing a shock absorbing member on the vehicle front side of the side frame in an automobile front structure having a side frame provided under a vehicle frame and extending in the vehicle front-rear direction. Background technique [0002] Historically, for example, it is known that as shown in Japanese Utility Model Laid-Open Publication No. 3-91282 (Japanese Utility Model Granted Publication No. 2514565), the frame of an automobile (i.e. vehicle) (e.g., equivalent to the front beam in this publication) 12) A front subframe consisting of a pair of left and right side frames extending in the front-rear direction of the vehicle to the vicinity of the front end of the frame is provided below. [0003] In addition, this publication also describes a structure in which a pair of left and right shock absorbing members (corresponding to the protruding portion 24 in this publ...
