Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear body structure of an automobile, and more particularly to a body structure of a joint between a side sill and a rear fender panel.

[0002]

2. Description of the Related Art For example, as shown in FIGS. 7 to 10, a sill outer panel 2 of a side sill 1 at the rear of a vehicle body has a stepped portion 3 formed outside the vehicle compartment. The lower edge of the rear fender panel 5 is joined by spot welding.

[0003] Specifically, the rear fender panel 5 includes:
Since the rear side door projects outside the vehicle compartment and is curved, a seal wall 6 of the rear side door which rises in an arc shape while protruding outside the vehicle compartment is provided. Is provided with a bumper bar receiving surface 8 of a rear side door.

The front edge 9 of the sealing wall 6 of the rear fender panel 5 and the joining surface 10 below the bumper rubber receiving surface 8 are spot-welded to the vertical wall 4 of the step portion 3 of the sill outer panel 2 by spot welding. (This similar structure is shown, for example, in Japanese Utility Model Application Laid-Open No. 64-5877).

[0005]

However, in the above-described conventional vehicle body structure, both the front edge 9 of the sealing wall 6 of the rear fender panel 5 and the joining surface 10 are formed by the vertical wall 4 of the step portion 3 of the sill outer panel 2. Seal wall 6 which rises in an arc while projecting outward because it is in the same plane
In the vicinity of the wheel arch portion 7 since the amount of projection of the vehicle exterior side of the sealing wall 6 is increased, the bonding surface 10 out many fold line L _1, L ₂ or the like on the surface to be connected to the sealing wall 6 There is a problem that the appearance is bad.

Further, if the bumper bar receiving surface 8 is made to protrude outward from the cabin in the same manner as the joint surface 10, the amount of embossing of the bumper bar mounting portion of the rear side door becomes large, which is not preferable in terms of door molding. Face 1
If the overhang amount is slightly larger than 0, the number of polygonal lines further increases around the bumper bar receiving surface 8 and the appearance is impaired.

Accordingly, the present invention provides a rear body structure of an automobile in which the rear side door can be easily formed without deteriorating the appearance.

[0008]

Means for Solving the Problems At the rear end of the side sill,
The vertical wall of the step portion of the sill outer panel is offset to the outside of the vehicle to form a protrusion, while the rear fender panel has
The seal wall of the rear side door that rises in an arc shape while protruding outside the vehicle compartment, and the front edge reaches the seal wall height along the projection of the sill outer panel at the corner part in front of the wheel arch part connected to this seal wall Form the bumper bar receiving surface of the rear side door that protrudes into
The front edge of the sealing wall of the rear fender panel and the lower part of the bumper rubber receiving surface are joined to the vertical wall of the sill outer panel.

[0009]

The bumper rubber receiving surface of the rear fender panel is formed so as to protrude to the outside of the cabin until its front edge reaches the seal wall height, thereby eliminating a drop between the bumper rubber receiving surface and the seal wall, reducing the number of broken lines, and reducing the bumper rubber receiving surface. Is joined to the protrusion of the vertical wall of the step portion of the sill outer panel to increase the support rigidity of the bumper rubber receiving surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings, in which the same reference numerals are given to the same parts as in the above-mentioned conventional construction.

As shown in FIG. 3, a step portion 3 is formed on the sill outer panel 2 of the side sill 1. A vertical wall 4 of the step portion 3 is offset from the rear side of the step portion 3 so as to project outward. The part 11 is formed. Incidentally, reference numeral 12 denotes a joining flange portion with a sill inner panel (not shown), and reference numeral 13 denotes a shelf portion.

On the other hand, as shown in FIG. 2, the rear fender panel 5 has, on the vehicle interior side, a flange 14 which is connected to an outer surface of a connection flange portion 12 of the sill outer panel 2 and a rear pillar inner panel (not shown). The front outer edge has a seal wall 6 of a rear side door 15 shown in FIG.

A front edge 16 protrudes to the outside of the vehicle cabin along a protrusion 11 of the vertical wall 4 of the sill outer panel 2 at a corner portion in front of the wheel arch 7 connected to the seal wall 6. The bumper rubber receiving surface 8 of the rear side door 15 is formed.

That is, the outer lower edge of the rear fender panel 5 is a sealing wall 6 on the front side, but goes rearward along the projection 11 of the vertical wall 4 of the sill outer panel 2 and thereafter largely outside the vehicle compartment. It is displaced to form the wheel arch 7.

1, 4 to 6, the upper surface 17 of the front edge of the rear fender panel 5 is spot-welded to the shelf 13 of the sill outer panel 2, and
The lower edge of the front outside of the vehicle cabin is spot-welded with the seal wall 6 to the front of the vertical wall 4 of the sill outer panel 2 and the lower part of the bumper rubber receiving surface 8 to the projection 11 of the vertical wall 4 of the sill outer panel 2, Rear fender panel 5 is replaced with sill outer panel 2
It is joined to. In addition, 18 in FIG. 5 shows a bumper bar.

According to the structure of the embodiment, the bumper bar receiving surface 8 of the rear fender panel 5 with which the bumper bar 18 of the rear side door 15 abuts protrudes outside the vehicle compartment until its front edge 16 reaches the height of the seal wall 6. Therefore, the height gap between the bumper rubber receiving surface 8 and the seal wall 6 is reduced, so that the number of broken lines on the surface connecting the seal wall 6 and the bumper rubber receiving surface 8 is reduced, and the appearance can be improved. .

Further, the bumper rubber mounting surface of the rear side door 15 has less unevenness by the amount that the bumper rubber receiving surface 8 protrudes to the outside of the cabin, and the formability of the rear side door 15 is improved.

Since the bump rubber receiving surface 8 is supported on the rear side by the projection 11 of the vertical wall 4 of the sill outer panel 2, the shelf 13 is not affected by the input load of the bump rubber 18.
Receives a load in the compression direction, the bumper bar receiving surface 8 is not deformed, and sufficient support rigidity can be secured.

[0019]

According to the present invention, as described above, the bump rubber receiving surface protrudes to the outside of the cabin until its front edge reaches the height of the sealing wall. The height gap is reduced between them, so that the surface connecting the bumper rubber receiving surface and the seal wall has fewer broken lines, and the appearance can be improved.

Further, the bumper bar mounting surface of the rear side door has less irregularities by the extent that the bumper rubber receiving surface protrudes to the outside of the passenger compartment, and the formability of the rear side door is improved.

Since the bumper bar receiving surface is supported on the rear side by the protrusion of the vertical wall of the sill outer panel, sufficient support rigidity can be secured without being deformed by the input load of the bumper bar.
