Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear vehicle body structure, and more particularly to a rear vehicle body structure in which a rear skirt flange portion is welded to a rear skirt.

[0002]

6 and 7 show a conventional rear vehicle body structure. In this conventional rear vehicle body structure, when connecting the rear floor 2 to the rear skirt 1, as shown in FIG.
The flange portion 2a of the rear floor is abutted against a, spot welded, and then the flange portion 2a of the rear floor 2
A sealer 3 was applied to the vicinity of the tip of the to seal the space between the rear skirt 1 and the rear floor 2.

In FIG. 6, 4 is a rear skirt 1.
7 is a tail end member connected to the upper end of the rear skirt 1 and an opening trim fitted to a portion connecting the upper end of the rear skirt 1 and the end of the tail end member 4.
In the figure, 6 is a housing rear combi outer 3 welded to the side of the rear skirt 1.

[0004]

By the way, in the conventional rear body structure, it is difficult to specify in which range the mating portion 1a of the rear skirt 1 is located, so that the flange portion 2a of the rear floor 2 remains displaced. It was sometimes welded. Thus, if the rear floor 2 is welded to the rear skirt 1 while being displaced from the predetermined position, it may interfere with the alignment with other components, and it may be difficult to attach the other components, and the displacement may occur. It is not easy to find the deviation from the outside, because the appearance does not appear in the appearance. Further, when the sealer 3 is applied to the vicinity of the tip of the flange portion 2a of the rear floor 2, the sealer gun (not shown) may be displaced during the sealing work, so that the sealing work between the rear skirt 1 and the rear floor 2 may be performed. Was not easy.

The present invention has been made in view of the above circumstances, and the flange portion of the rear floor can be easily welded to a predetermined position of the rear skirt, and the sealing work between the rear skirt and the rear floor can be facilitated. It is an object to provide a rear body structure that can be performed.

[0006]

In order to achieve the above object, in a rear vehicle body structure in which a flange portion of a rear floor is welded to a rear skirt, beads are formed above and below a mating portion of the rear skirt with the rear floor. Of the above beads, the upper bead is projected to the outside of the room on the opposite side of the rear floor of the rear skirt where the rear floor meets, and the lower bead on the same side as the rear floor where the rear skirt meets the rear floor. together to protrude toward the cabin, spaced apart by a width substantially equal to those beads to the width of the top to extend the <br/> flange portion of the rear floor, the upper and lower ends of the flange portion extending upward rear floor respectively The structure is formed so as to follow the shape.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a rear vehicle body structure according to the present invention will be described below in detail with reference to the accompanying drawings. 1 to 5 show an embodiment of a rear vehicle body structure according to the present invention. The rear vehicle body structure of this embodiment has a rear skirt 11 of a vehicle 10, a flange portion 12a of a rear floor 12 and a rear skirt 11.
And a bead 1 is formed above and below the mating portion 11a of the rear skirt 11 with the rear floor 12, respectively.
3 and 14 are formed.

The beads 13 and 14 are formed so as to be separated by a width substantially equal to the width of the flange portion 12a of the rear floor 12, and are formed so as to follow the shapes of the upper and lower ends of the flange portion 12a of the rear floor 12, respectively. Moreover, the upper bead 13 is projected toward the outdoor side, and the lower bead 14 is protruded.
Is projected toward the indoor side.

In FIG. 1, reference numeral 15 denotes a housing rear combi-outer welded to a side portion of the rear skirt 11,
16 is a rear bumper, and in FIG. 2, 17 is a tail end member connected to the upper end of the rear skirt 11,
18 is the upper end of the rear skirt 11 and the tail end member 1
5 is an opening trim fitted to a portion where the end portion of 5 is connected.

In this embodiment, when connecting the rear floor 12 to the rear skirt 11, as shown in FIG. 4, the flange portion 12a of the rear floor is abutted against the mating portion 11a of the rear skirt 11 with the rear floor 12. , Spot welding. This welding operation is performed with the flange portion 12a of the rear floor 12 placed on the bead 14 below the rear skirt 11.

As a result, the flange portion 12a of the rear floor 12 can be easily positioned at the mating portion 11a of the rear skirt 11 and the drop before welding can be prevented. Therefore, the welding work of the rear floor 12 to the rear skirt 11 can be performed easily and quickly. Moreover, by observing how the flange portion 12a of the rear floor 12 hits the bead 14, the displacement of the flange portion 12a of the rear floor 12 can be found by direct visual observation from the outside.

Also, the flange portion 12a of the rear floor 12
Is extended upward so that the front end of the flange portion partially overlaps with the upper bead 13 in a state of being welded to the mating portion 11a of the rear skirt 11. Therefore, at the time of performing the sealing work between the rear skirt 11 and the rear floor 12 performed thereafter, the sealing work can be performed by guiding the sealer gun 19 with the tip of the flange portion 12a or the bead 13, and thus the sealing work is easy. It can be done quickly and quickly.

Moreover, in the sealing work at this time,
Since it is sufficient to fill the space formed between the recess of the bead 13 on the upper side of the rear skirt 11 and the flange portion 12a of the rear floor 12 with the sealer 20, the seal application work can be reliably performed.

[0014]

As described above, according to the rear vehicle body structure according to the present invention, in the rear vehicle body structure in which the flange portion of the rear floor is welded to the rear skirt, the upper and lower parts of the mating portion of the rear skirt with the rear floor are provided. Form each bead and attach these beads to the flange on the rear floor.
Separate the rear floor flaps by a width that is approximately equal to the width.
Since the configuration is formed so as to follow the shape of the upper and lower ends of the lunge part, the alignment part is limited between the upper and lower beads, so that the flange part of the rear floor can be easily aligned and the surface management can be performed. Will be easier.

Of the above beads, the upper bead is
With the rear floor of the mating part with the rear floor of the rear skirt
It is is projected to the exterior side of the opposite side, Riyasuka the lower bead
By projecting to the inside of the room on the same side as the rear floor of the mating part with the rear floor of the seat, sealer application can be performed using these beads as marks or guides, improving sealing workability. Can be planned. Moreover,
By providing the beads on the rear skirt, when the rear floor is assembled, it is possible to easily find the deviation, and since the rigidity of the rear skirt is increased, the holding strength of the rear floor can be improved. it can.

Furthermore, so as to overlap partially and the upper bead, with the construction in which the extended flange portion of the rear floor upwards, in the sealing work in between the rear skirt and the rear floor, the flange portion
Guide the sheer gun by the tip or bead of
Sealing work can be done, so sealing work is easy
And it can be done quickly. Further, since it suffices to fill the space formed between the bead on the upper side of the rear skirt and the flange portion of the rear floor with the sealer, the seal application work can be reliably performed.

Furthermore, the flange portion of the rear floor
By forming the lower bead so that the lower side is placed on the upper part of the lower bead, the flange portion of the rear floor can be easily positioned at the mating portion of the rear skirt and the welding can be performed. It is possible to prevent the drop. Therefore, the work of welding the rear floor to the rear skirt can be performed easily and quickly. Moreover, by observing how the flange portion of the rear floor comes into contact with the bead, it is possible to directly find the displacement of the flange portion of the rear floor by visual observation from the outside.
