Embodiment Construction

[0053] One embodiment of the present invention will be described below with reference to the drawings. In the following description, the front body structure of the automobile will be described with respect to one side (right side) in the vehicle width direction, but the same applies to the other side (left side). In addition, each direction of front / rear, inner / outer, and upper / lower shown in each drawing means each direction of the front-back direction of a vehicle, the vehicle width direction, and an up-down direction unless otherwise specified.

[0054] (Overall composition of the front body structure)

[0055] Such as figure 1 and figure 2As shown, the front body structure 1 includes: a hinge pillar 2 extending up and down at the front side of the vehicle compartment; an apron reinforcement 3 connected to the upper part of the hinge pillar 2 and extending forward; The side rail 4 extending rearward, and the diagonal rib reinforcement 5 connecting the apron reinforceme...

Abstract

A front vehicle-body structure that can increase the support rigidity of the apron reinforcement with the bracing reinforcement is provided. The front vehicle-body structure includes: a hinge pillar (2) extending vertically; a suspension housing (6) spaced forward from the hinge pillar (2); an apron reinforcement (3) that extends forward from an upper part of the hinge pillar (2), has a closed section perpendicular to a front-rear direction, and supports the suspension housing (6); a bracing reinforcement (5) that extends rearward to be inclined downward so as to couple a lower part of the apron reinforcement (3) and the hinge pillar (2) in a bracing manner, and has a closed section perpendicular to a direction of the extension; and a first reinforcing member (70) that is provided inside the closed section of the apron reinforcement (3) and partitions the closed section in the front-rear direction. The bracing reinforcement (5) includes, at a bottom, a wheel well outer rear part (92) extending rearward to be inclined downward, and the first reinforcing member (70) is connected to the wheel well outer rear part (92).

Description

technical field [0001] The present invention relates to front body construction. Background technique [0002] There is known a front body structure including: a hinge pillar extending in the vertical direction, an apron reinforcement extending forward from an upper portion of the hinge pillar, a suspension housing supported by the apron reinforcement, The reinforcement in the shape of oblique ribs is connected between the reinforcement and the hinge column in the form of oblique ribs. [0003] The upper end of the shock absorber included in the suspension for supporting the front wheel is supported on the suspension housing. When viewed from the front of the vehicle, the shock absorber is sometimes attached to the suspension housing with its axis facing upward and inclined inward in the vehicle width direction. The inner component in the width direction is likely to be deformed so that the suspension shell falls in a direction inclined downward toward the inner side in th...
