Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to the front body structure of an automobile, and more particularly to the structure of the connecting portion between the front pillar and the dash panel.

(Prior art) Usually, the front body structure of an automobile is
As described in Japanese Patent No. 57-204274, a dash panel (also called a cowl top) extending in the width direction of the vehicle body is provided between the left and right front pillars extending up and down on the sides of the front window. In the invention described in the above-mentioned Utility Model Publication, an instrument panel bracket that connects the inside of the front pillar and the dash panel is finally provided by bolting, thereby increasing the rigidity of the front vehicle body.

(Problem to be solved by the invention) The lower part of the front pillar is joined to the upper part of the hinge pillar where the door hinge is installed, but in order to increase the strength of this joint and the rigidity of the front pillar itself, Preferably, reinforcement is arranged inside the pillar. Furthermore, an instrument panel bracket that connects the inner surface of the front pillar and the dash panel is provided after the inner member of the front pillar is attached to the inner member of the hinge pillar and before the above-mentioned reinforcing member of the front pillar is provided. This is preferable because it is possible to improve the joint strength of this joint portion and also to improve workability.

However, if the assembly procedure is to install the instrument panel bracket on the inner member of the front pillar before installing the reinforcing material for the front pillar, there is a problem that the reinforcing material for the front pillar cannot be provided on the inner member of the front pillar by spot welding. A point occurs.

(Means for Solving the Problems) The above problems are solved by the front body structure of an automobile according to the present invention. That is, the front body structure of an automobile of the present invention is composed of: an outer member and an inner member, and left and right front pillars extending to the sides of the front window; an outer member and an inner member, which are joined to the lower part of the front pillar; left and right hinge pillars on which door hinges are provided; a darts panel provided between the left and right front pillars; a reinforcing material provided inside the front pillar; and an opening for welding the reinforcing material to the front pillar. A box-shaped instrument panel bracket connects the inner member of the front pillar, the inner member of the hinge pillar, and the dash panel.

(Function) The instrument panel bracket used in the present invention is provided with an opening, through which the reinforcing material can be spot welded to the inner member of the front pillar.

(Effects of the invention) With this invention, work can be carried out with the instrument panel bracket increasing the joint strength between the inner member of the front pillar and the inner member of the hinge pillar, and the reinforcing material can be inserted into the spot through the opening of the bracket. Since it can be joined, work can be done efficiently.
Further, since the reinforcing material is arranged inside the front pillar, the mounting strength of the front pillar and the rigidity of the front pillar itself are increased.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. Fig. 3 is a diagram showing the assembly process of an embodiment of the front body structure of an automobile according to the present invention, and Fig. 4 is a partially enlarged view. The lower inner side of the hinge pillar is joined to the upper outer side of the inner member 2 of the hinge pillar by spot welding. Figure 1 is a perspective view when assembly is completed, and Figure 2 is a cross-sectional view of Figure 1.
As can be seen from the figure, the box-shaped first instrument panel (hereinafter referred to as the instrument panel) having a joining flange at its edge has a bracket component 3 located inside the inner member 1 of the front pillar and the inner member 2 of the hinge pillar. The joints are joined by spot welding. Note that the first instrument panel bracket 3 may be configured in a box shape with two parts. Since this instrument panel bracket 3 is attached across both the front pillar inner member 1 and the hinge pillar inner member 2, the attachment strength of the front pillar inner member 1 is increased, and workability in subsequent processes is improved. Further, an opening 4 is provided on the side surface of the instrument panel bracket 3, and through this opening 4, a reinforcing member 5 can be attached to the outside of the inner member 1 of the front pillar by spot welding.

After the reinforcing member 5 is attached, the outer member 6 of the front pillar having a U-shaped cross section is joined to the inner member 1 and the reinforcing member 5 by welding to assemble the front pillar 7 having a closed cross section. A dash panel 8 extending in the vehicle width direction is provided between the left and right front pillars 7, and the front pillar 7 and the dash panel 8 are connected by a second instrument panel bracket having a U-shaped cross section and a joining flange at the edge. It is reinforced by part 9.

The joining flange of this instrument panel bracket component 9 is connected to the front pillar inner member 7 and the first instrument panel bracket component 3 by arc welding or the like.
and is joined to the dash panel 8. This constitutes an instrument panel bracket 10 that connects the front pillar inner member 1, the hinge pillar inner member 2, and the dash panel 8. It goes without saying that the outer member of the hinge panel is provided outside the inner member 2 of the hinge panel.
