[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a coupling structure in the case where there is a variation in the number of panels coupled by means such as spot welding, an adhesive, and bolts, such as a pillar in a vehicle.
[0002]
[Prior art]
In the commercial vehicle, as illustrated in FIGS. 5 and 6, the front pillar 2 of the cab 1 connects the flange portion 4 of the outer panel 3 and the flange portion 6 of the inner panel 5 by spot welding or the like, Although it has a closed cross-sectional structure, when it is necessary to reinforce the front pillar 2 depending on the application of the vehicle, etc., a reinforcing panel 7 is conventionally arranged between the panels 3 and 5 and between the flange portions 4 and 6. The flange portions 8 of the reinforcing panel 7 are sandwiched between the flange portions 4, 6, and 8 so as to be integrally coupled by spot welding or the like. Reference numeral 9 denotes a windshield.
[0003]
However, comparing the case where the reinforcing panel 7 is arranged with the case where the reinforcing panel 7 is not arranged, if the outer dimensions of the front pillars 2 arranged on the left and right are constant, the front pillar 2 is used in the former case. The inner method W is less than the latter case by twice the thickness d of the flange portion 8 of the reinforcing panel, and as a result, the interior width is narrowed. It is necessary to change the mounting angle at the left and right ends of each of the fitting parts such as the panel and the front pillar trim, that is, the portion contacting the inner side surface of the front pillar 2 from the latter case, and the cab 1 is welded. The assembly jig also needs to be changed from the latter case, and there is a problem that the manufacturing cost is remarkably increased.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described.
1 to 3, a front pillar 10 in a commercial vehicle cab includes an outer panel 11, an inner panel 12, and a reinforcing panel 13 disposed between both the panels 11 and 12, and the flange portion 14 of the outer panel 11 is flat. On the other hand, the flange portion 15 of the inner panel 12 is provided with a protruding step portion 16 spaced vertically in the longitudinal direction, and the height of the protruding step portion 16 is made equal to the plate thickness of the reinforcing panel 13. ing.
[0008]
Further, a notch 18 is formed in the edge 17 of the reinforcing panel 13 at a portion that matches the protruding step 16 of the inner panel 12, and the protruding step 16 of the inner panel 12 overlaps the flange 14 of the outer panel 11. In addition, the protruding step portion 16 of the inner panel 12 is positioned in the notch 18 of the reinforcing panel 13, and the protruding step portion 16 is formed in the flange portion 14 of the outer panel 11 and the flange portion 15 of the inner panel 12. The end edge 17 of the reinforcing panel 13 is combined so as to be inserted into a gap formed between the portion and the portion not formed.
[0009]
Further, a portion A where three pieces of the flange portion 14 of the outer panel 11, the end edge 17 of the reinforcing panel 13, and the flange portion 15 of the inner panel 12 where the projecting step portion 16 is not formed is spotted. A portion B where the flange portion 14 of the outer panel 11 and the protruding step portion 16 of the inner panel 12 are overlapped is joined by spot welding or the like, and the front pillar 10 is closed cross-sectional structure. Is forming.
[0010]
On the other hand, as shown in FIG. 4, in the front pillar 20 that is not particularly required to have strength, the reinforcing panel 13 is removed from the front pillar 10, the flange portion 14 of the outer panel 11, and the inner panel. The portions B where the 12 protruding step portions 16 are superimposed are joined by spot welding or the like, but the protruding step portion 16 is not formed in the flange portion 14 of the outer panel 11 and the flange portion 15 of the inner panel 12. A gap 21 is still formed between the portions.
[0011]
That is, the cab using the front pillar 10 in which the reinforcement panel 13 is incorporated because the strength is particularly required, and the front pillar 20 in which the reinforcement panel 13 is not incorporated because the strength is not particularly required. Since the overall thickness of the flange portion of the front pillars 10 and 20 is the same as that of the used cab, the outer dimensions and inner methods in the vehicle width direction of the left and right front pillars 10 and 20 are all the same. Since the instrument panels and front pillar trims installed inside the cab can be made to have the same overall length, and the mounting angles at the left and right ends of each of these equipment parts, each equipment part for both types of cabs can be made common. Therefore, the welding assembly jigs for both types of cab are also the same. Results it is possible to use those, there is a great advantage that it is possible to suppress low the manufacturing cost of the cab.
[0012]
In the above embodiment, the flange portion of the outer panel is flat and the protruding step portion is formed on the flange portion of the inner panel. However, if necessary, the flange portion of the inner panel is flattened, and the flange of the outer panel is formed. A protruding step portion can be formed on the portion, and a plurality of panels can be used as a reinforcing panel. Further, each of the above structures can be used as a side floor frame or roof in a commercial vehicle cab. Needless to say, the present invention can be applied to the front pillars, center pillars, rear pillars, side sills, roof side rails and the like in passenger cars as well as the side rails as necessary.
