Description

[Detailed description of the invention] The present invention relates to the improvement of the cowl part of an automobile body, and is a cowl part that can simplify the welding work of the cowl part when assembling the car body, and makes it possible to automate the welding work, Another object of the present invention is to provide a cowl part that can increase the strength of the joint between the front pillar and the cowl part without increasing weight or complicating the structure.

The cowl part of a conventional automobile body is constructed by welding a cowl outer plate, a cowl inner plate, a cowl top side plate, etc. to the cowl side plate, and then covers the outer surface of the cowl side lower plate. It is welded, and not only does the welding work become complicated, but the joint between the cowl member and the front pillar is
As shown in FIG. 8, the outer rear end A of the cowl side plate and the rear end B of the cowl inner plate are connected to the front pillar outer plate C.
The single bond was welded at welding point D, which had the disadvantage of low strength.

As a way to compensate for this drawback, the
The structure shown in Publication No. 108974 has also been proposed, but it requires a large reinforcement on the front pillar and a mounting overlapping part on the pillar outer, resulting in a complicated structure that also increases weight and processing man-hours. It has some drawbacks.

By adopting the configuration described in the claims for utility model registration, the present invention does not have the above-mentioned drawbacks, the welding work is simplified, the strength of the joint with the front pillar is high, and there is no increase in weight or assembly man-hours. This provides a relatively simple cowl structure that does not involve any problems such as the following.

The configuration of the illustrated example will be explained below.

In the figure, the outer end 2 of the cowl outer plate 1
is welded at a welding point 5 to the top plate part 4 of the cowl top side plate 3, which has a substantially inverted U-shaped cross section in the vehicle width direction. is welded at the same welding point 12 to the outer end 9 of the horizontal portion of the cowl inner plate 8, which has a substantially inverted L-shaped cross section, and to the upper end 11 of the cowl side plate 10, which has the rear wall forming portion of the wheel house. .

And, an outer end 2 of the cowl outer plate 1,
The outer part 6 of the cowl top side plate 3 , the cowl side plate 10 and the cowl side plate 10 together form a cowl portion outer wall 14 that is continuous with a front pillar 13 .

Also, the outer 6 of the cowl top side plate 3
The rear end 15 of the front pillar outer plate 1
6 at a welding point 17, and a rear end 19' of the inner part 18 of the cowl top side plate 3, which hangs downward;
The rear end 19 of the rising portion of the cowl inner plate 8 is welded to the front pillar inner plate 20 at the same welding point 21.
A connecting portion 22 between the cowl and the cowl has a closed cross-sectional structure.

The cowl part according to the present invention has the configuration described above, and is an assembly in which the cowl outer plate 1 and the cowl top side plate 3 are welded at the welding point 5 and are assembled integrally with the cowl inner plate 8.
Welding point 1 at the upper end 11 of the cowl side plate 10
2, welding the rear end 15 of the outer 6 of the cowl top side plate 3 to the front pillar outer plate 16, and welding the rear end 19' of the inner 18 of the cowl top side plate 3 to the cowl inner plate 8. By welding the rear end 19 to the front pillar inner plate 20 at the welding point 21, the formation of the cowl outer wall 14 and the connection of the cowl and the front pillar 13 can be realized. The number of welding points is small, the welding work can be simplified, and the welding work can be easily automated.

Further, since the joint portion 22 between the cowl portion and the front pillar 13 has a closed cross-sectional structure, it also has the effect of significantly improving strength.

Furthermore, since no reinforcement is required, the strength can be increased without increasing weight or assembly man-hours.
