Problems solved by technology

[0003]However, even if the front side member is bent at the first and second planned bending portions, when the impact load cannot be sufficiently absorbed by the bending , it may cause the rear end of the above-mentioned front side member to move rearward together with the dash panel, for example
In addition, in some cases, the rear side of the front side member is provided with a curved portion that bends downward and extends below the dash panel. In the case of such a structure, if the impact load is not sufficiently absorbed, the above-mentioned damage may occur. The front side member is broken at the above-mentioned bending part and moves backward

Embodiment Construction

[0045] Next, a front body structure of an automobile according to a preferred embodiment of the present invention will be described.

[0046] As shown in Figure 1 (refer to Figures 2 to 4 as appropriate), in the automobile 1 of this embodiment, at the left and right ends of the dash panel 2, there are respectively provided front doors (not shown) that extend in the up and down direction and are pivotally supported. The hinge pillar 3 (only one side is shown in the figure).

[0047] The fender reinforcements 4, 4 extend forward from the upper portions of the left and right hinge pillars 3, respectively.

[0048] The front side members 5, 5 extend in the front-rear direction of the vehicle body at positions substantially parallel to the fender reinforcements 4, 4 in plan view and at positions spaced inward in the vehicle width direction by a certain distance.

[0049] A wheel house 6 for a front wheel is provided between the fender reinforcement 4 and the front side member 5 in...

Abstract

A front side frame includes a bend portion which is operative to bend outward when an impact load acts on the front side frame from ahead. The bend portion is provided in a specified location such that the bend portion in a bending state substantially contacts a damper of the suspension from a vehicle front side. Accordingly, a rear end of the front side frame can be prevented properly from moving back when the impact load acts on the front side frame from ahead.

Description

technical field [0001] The present invention relates to the front body structure of automobiles, and more particularly to impact-absorbing structures. Background technique [0002] For example, Japanese Patent Laid-Open Publication No. 2003-220977 discloses, as a front body structure of an automobile, a structure having a pair of left and right front side members extending in the front-rear direction of the vehicle body in front of the dash panel. In this configuration, the front side member is provided with first and second planned bending portions for allowing the front side member to bend in the vehicle width direction when an impact load is applied from the front of the vehicle body. Accordingly, the impact load acting on the front side member is absorbed by the bending of the first and second intended bending portions. [0003] However, even if the front side member is bent at the first and second planned bending portions, if the impact load cannot be sufficiently abso...
