Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body structure capable of improving rigidity and assembling performance.

[0002]

2. Description of the Related Art FIG. 5 shows three removable roofs 1,
1 shows an open car in which a roll bar 3 and a back window glass 4 provided at a rear portion of a vehicle body 2 can be rotated to be stored behind the vehicle body.

In the body structure of this open car, as shown in FIG. 6, a bulkhead 6 is erected at a rear end portion of a main floor panel 5, and a seat is arranged on the main floor panel 5 to seat passengers. Is provided. The front end of the rear floor panel 7 is joined to the upper end of the bulkhead 6, and a partition panel 8 for partitioning the trunk is set up in the middle of the rear floor panel 7. A cabin back trim 9 is arranged inside the partition panel 8, and a storage portion for the roll bar 3 and the back window glass 4 is formed between the cabin back trim 9 and the partition panel 8.

A floor tunnel 10 is arranged in the front-rear direction of the vehicle body between the left and right seats of the main floor panel 5, and a console box 11 and the like are provided on the floor tunnel 10.

As shown in FIG. 7, a reinforcing cross member 12 and a seat rail inside bracket 13 for seat rail mounting are joined to the main floor panel 5 in a direction intersecting with the floor tunnel 10 by arc welding.

[0006]

However, the cross member 12 and the seat rail inside bracket 1 are to be solved.
When the end face of 3 is joined to the floor tunnel 10 by arc welding, since the plate thickness of the floor tunnel 10 is thin, there is a possibility that the joining face may be dented or warped during welding to form a gap. For this reason, it takes time to perform welding work,
Alternatively, the gap creates a place where welding is impossible. In this case, if the thickness of the floor tunnel 10 is increased, the weight increases, which is against the weight reduction of the vehicle body.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide a vehicle body structure capable of improving the rigidity of a floor tunnel and improving the efficiency of welding work.

[0008]

In order to solve the above problems, the present invention provides a vehicle body structure in which an end surface of a member disposed in a direction intersecting with a floor tunnel is joined to a side surface of the floor tunnel on a vehicle body floor panel. In the above, the concave bead is provided on the joint surface of the floor tunnel with the joint member.

[0009]

[Operation] A concave bead is provided on the side of the floor tunnel to improve the rigidity of the floor tunnel.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, description will be given with reference to FIGS. 1 to 4 in which the same parts as those in FIGS. 6 and 7 are designated by the same reference numerals and the description thereof is omitted.

In FIGS. 1 and 2, on both side surfaces 14 of the floor tunnel 10, the joint end surface 1 of the cross member 12 is provided.
Recessed beads 15 and 16 are provided in the vertical direction so as to correspond to the joining end surface 13a of the seat rail inside bracket 13 and 2a. The concave bead 15 is the cross member 12
The concave bead 16 is provided at a position hidden by the joint end face 12a of the seat rail inside the seat rail inside bracket 13 and extends outside the joint end face 13a of the seat rail inside bracket 13.

The floor tunnel 10, as shown in FIG.
Tunnel side members 1 along the front-rear direction on the left and right inner surfaces
7 are joined, and between the tunnel side members 17,
The floor tunnel insulator 18 and the floor tunnel lower cover 19 are joined together.

The lengths of the concave beads 15 and 16 are the same as those applied to the cross member 12 so as to be hidden inside the joining end surface 12a, and the lengths of the joining end surface 13a as applied to the seat rail inside bracket 13. It may extend to the outside and be formed.

According to the above construction, when the cross member 12 and the seat rail inside bracket 13 are spot-welded to the side surface 14 of the floor tunnel 10, the joining end surface 12a of the cross member 12 and the seat rail inside are attached to the side surface 14 of the floor tunnel 10. Since the concave beads 15 and 16 are formed corresponding to the joining end surface 13a of the bracket 13, the rigidity of the joining surface is improved. Therefore, the side surface 14 of the floor tunnel 10 is not dented or warped during the joining work.

The concave beads 15 and 16 are provided with a floor tunnel portion 20 and a main floor panel portion 21 as shown in FIG.
It can also be applied to those integrally formed with and. Two
2 is a side sill part.

[0016]

As described above, according to the vehicle body structure of the present invention, the concave bead is provided on the side surface of the floor tunnel. Can be prevented. Therefore, the efficiency of the welding work can be improved and the rigidity of the floor tunnel can be improved.

According to the above construction, when the cross member 12 and the seat rail inside bracket 13 are arc-welded to the side surface 14 of the floor tunnel 10, the joint end surface 1 of the cross member 12 is attached to the side surface 14 of the floor tunnel 10.
Since the concave beads 15 and 16 are formed corresponding to the joint end surface 13a of the seat rail inside bracket 13 and 2a, the rigidity of the joint surface is improved. Therefore, the side surface 14 of the floor tunnel 10 is dented during the joining work,
It does not warp.
