Description

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

(Prior Art) Generally, the rear side of a cowl side panel provided in the longitudinal direction of a vehicle body is joined to a pillar inner panel of a front pillar (see Japanese Utility Model Publication No. 57-37089).

By the way, in such a conventional joining structure, as shown in FIGS. 1 and 2, the edge flanges of the dart upper panel and the cowl plate upper panel are overlapped and joined to the upper end of the cowl side panel 1. A flat flange 1a is formed for this purpose, and this flat flange 1a terminates in front of the front end joining flange 2a of the front pillar 2, and the cowl side panel 1 goes around inside the pillar inner panel 3 of the front pillar 2. It is designed to be joined to the pillar inner panel 3 in this state.

In this case, in order to allow the cowl side panel 1 to go around the inside of the pillar inner panel 3 of the front pillar 2, a notch 4 must be inevitably inserted at the end of the flat flange 1a of the cowl side panel 1. Because of this notch 4, a gap 5 is created between the front end joining flange 2a of the front pillar 2 and the cowl side panel 1, and there is a problem in that rainwater or the like can enter the vehicle interior through this gap 5.

(Purpose of the invention) The object of the invention is to provide an automobile capable of reliably closing the gap formed by the notch of the cowl side panel between the front end joining flange of the front pillar and the flat flange of the cowl side panel. The purpose is to provide a front body structure.

(Structure of the invention) Therefore, in the invention, a cover flange that covers the gap between the flat flange of the cowl side panel and the front end joining flange of the front pillar is
It is characterized by being continuously provided on the front end joining flange of the front pillar.

(Effects of the invention) According to the invention, the sealing performance between the cowl side panel and the front pillar is improved, the intrusion of rainwater etc. can be prevented, and it is advantageous in terms of rust prevention. Since the joining work can be performed while the cover flange of the front pillar is overlapped with the flat flange of the cowl side panel, the joining work efficiency is also improved.

(Example) Hereinafter, embodiments of the present invention will be described in detail.

As shown in FIGS. 3 and 4, the front pillar 12 includes a front end joint flange 15 formed by joining the front end flange 10a of the pillar outer panel 10 and the front end flange 11a of the pillar inner panel 11, and A rear end flange 10b and a rear end joint flange 19 formed by joining the rear end flange 11b of the pillar inner panel 11 form a closed cross section, and the front pillar 12 has a rear end flange 19 provided in the longitudinal direction of the vehicle body. The rear side of the cowl side panel 13 is joined.

At the upper end of this cowl side panel 13, a fifth
As shown in the figure, a plane flange 14 is formed which is bent outward at a substantially right angle, and the rear side of this plane flange 14 terminates in front of the front end joining flange 15 of the front pillar 12. This plane flange 14 includes, although not specifically shown,
The edges of the dash upper panel and the cowl plate upper panel are overlapped and joined.

On the other hand, the upper part of the cowl side panel 13, which is continuous with the terminal end 14a of the flat flange 14 of the cowl side panel 13 with the notch 17 in between, is attached to the vehicle body along the cross-sectional shape of the front end side of the pillar inner panel 11 of the front pillar 12. An inclined surface portion 18 projecting outward in a substantially V-shape is formed, and this inclined surface portion 1
8 is the front end joint flange 15 of the front pillar 12
The rear end flange 20 provided along the rear edge of the cowl side panel 13 is welded to the inside of the front pillar 12.
It is welded to 9.

Due to the notch 17, a gap 21 is created between the terminal end 14a of the flat flange 14 of the cowl side panel 13 and the front end joining flange 15 of the front pillar 12. 15 from the outside.

That is, the front end joining flange 15 has a horizontal cover flange 15b that protrudes forward from the inclined surface portion 15a along the upper surface of the flat flange 14 of the cowl side panel 13 so as to cover the gap 21.
are integrally formed, and the side edge side of the plane flange 14 continues from the cover flange 15b,
That is, a wrap-around portion 15d is formed that wraps around from the outside of the vehicle body and continues to the vertical portion 15c of the front end joining flange 15.

The cover flange 15b of the front end joining flange 15 is welded to the upper surface of the flat flange 14 of the cowl side panel 13 while covering the gap 21.
c is welded to the cowl side panel 13.

With the above structure, the gap 21 will be covered from above and outside by the cover flange 15b and wrap-around portion 15d of the front end joint flange 15 of the front pillar 12, and the sealing performance will be improved and the gap 21 will be covered from above and outside. It is possible to reliably prevent the infiltration of rainwater, etc.

Furthermore, when joining the cowl side panel 13 and the front pillar 12, the joining work can be performed with the flat flange 14 of the cowl side panel 13 and the cover flange 15b of the front pillar 12 fitted together, thereby improving the efficiency of the joining work.

In the above embodiment, the cover flange 15b was provided on the front end joint flange 15 of the front pillar 12, but the pillar outer panel 10
A cover flange may be provided on either the front end flange 10a of the pillar inner panel 11 or the front end flange 11a of the pillar inner panel 11.
