[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body structure of a sliding door car, and more particularly to a vehicle body reinforcement structure of a vehicle which is opened and closed by sliding a front side door.

[0002]

FIG. 3 shows a sliding door wheel car.
In this sliding door car, guide rails 4, 5, and 6 are provided on the roof rail 1, the middle of the side body 2, and the side sill 3, and the front side door 7 is guided by the guide rails 4, 5, and 6.

FIG. 4 shows a side body inner of such a sliding door car, and FIG. 5 shows a vehicle body structure of a portion corresponding to a line VV in FIG. In this sliding door car, as shown in FIG. 5, the guide rail 5 is arranged on the outer surface of the side body outer 8, and the bolt 9 planted on the guide rail 5 is inserted through the hole 8a of the side body outer 8. The guide rail 5 is fixed to the side body outer 8 by screwing a nut 10 to the tip of the bolt 9. The tightening work of the nut 10 is performed through the hole 11 a of the side body inner 11.

[0004]

By the way, a seat belt retractor mounting bracket 12 is fastened to the side body inner 11 by bolts 13 and nuts 14 as shown in FIG. Therefore, the side body inner 11 must have considerable strength. However, in order to increase the strength of the side body inner 11, increasing the thickness thereof
It is not preferable because the weight of the vehicle increases.

In order to increase the strength of the side body inner 11 without increasing the thickness of the side body inner 11, a reinforcement is interposed between the side body inner 11 and the side body outer 8. However, it is difficult to connect the side body outer 8 and the reinforcement to each other without affecting the appearance of the side body outer 8. That is,
When bound by a bolt, the bolt head will be exposed to the outer surface of the side body outer 8, also be attached by spot welding, to the outer surface of the side body outer 8 sports
Dents caused by dents.

Accordingly, an object of the present invention is to provide a sliding door vehicle capable of increasing the strength of the side body inner without increasing the thickness of the side body inner and without impairing the appearance of the side body outer. To provide a vehicle body structure.

Bolts 28 and nuts 26
Thus it was solved to the body structure of the sliding-door vehicle according to claim.

[0008]

[Function] In the vehicle body structure of the sliding door car of the present invention, the reinforcement of the side body inner is sufficiently obtained because the reinforcement is interposed between the side body outer and the side body inner. Is coupled to the side body outer together with the guide rail of the sliding door by fastening together, so that the outer appearance of the side body outer is not affected.

[0009]

FIG. 1 shows a vehicle body structure of a sliding door vehicle according to the present invention, and shows only a main part of a side body inner. FIG. 2 is a cross-sectional view showing a vehicle body structure of a portion corresponding to line II-II in FIG.

In this sliding door wheel, a guide rail 22 is provided on the outer surface of the side body outer 21 similarly to the above-mentioned conventional sliding door wheel. The front end 23 a of the side body inner 23 has a side body outer 21.
Spot welded to the front end of

Further, in this sliding door vehicle, a crank-shaped reinforcement 24 is interposed between the side body outer 21 and the side body inner 23. One end 24a of the reinforcement 24
Are fixed to the side body inner 23 by welding or the like. A hole 25 is formed at one end 24a of the reinforcement 24, and a nut 26 is welded to a position corresponding to the hole 25. A hole 27 is also formed at a position of the side body inner 23 corresponding to the hole 25 of the reinforcement 24. Here, a bracket 29 of the seat belt retractor is fixed by a bolt 28 screwed into a nut 26 through the holes 27 and 25. This bra
The cover 29 is not limited to the seat belt retractor,
The bracket of the member may be used.

A hole 30 is also formed at the other end 24b of the reinforcement 24. The end 24b of the reinforcement 24 is fixed to the side body outer 21 as follows. The bolt 31 implanted in the guide rail 22 is inserted into the hole 32 of the side body outer 21 and the hole 3 of the reinforcement 24.
0, the nut 33 is screwed into the tip of the bolt 31, and the guide rail 22, the side body outer 21,
The reinforcement 24 is integrated. At this time, the fastening work of the nut 33 is performed by the hole 34 of the side body inner 23.
Done through.

[0013]

As described above, in the vehicle body structure of the sliding door car according to the present invention, the reinforcement is interposed between the side body outer and the side body inner, and the side body outer side of the reinforcement is provided. The end is jointly fastened to the side body outer using a guide rail mounting bolt.
