Description

[Detailed description of the invention] This invention relates to a vehicle body structure, and in particular, a rear fender panel has an opening for mounting a fixed window (hereinafter referred to as an opera window), and the front end of the rear fender panel The present invention relates to a vehicle body structure suitable for an automobile, which is welded and fixed to the rear end of a side roof rail that ends in front of an opening.

Conventionally, as this type of joining structure, the structures shown in FIGS. 1 to 3 are known.

In this joint structure, the front end Ff of the rear fender panel F is welded to the side roof rail 3, and the rear upper end Fr is welded to the rear roof rail 4.
A roof panel L was attached to cover the upper ends of the side roof rails 3 and rear fender panel F.

However, in the case where the rear end Lr of the roof panel L is configured to overlap with the upper part of the vertical surface of the rear fender panel F, in particular, there is no opera window in the rear quarter part of the rear fender panel F. If the mounting opening 6 is formed, the rear end Lr of the roof panel L
In order to prevent the opera window glass surface from protruding from the outer surface of the vehicle body, the recess 7 that fits into and overlaps the mounting opening 6 must be partially inverted as shown in FIG. The moldability of the roof panel L was poor.

Further, when the roof panel L is formed as described above, the edge 7a of the recess 7 and the opening edge of the rear fender panel F and the inside panel 2
Fa, 2a were spot welded, and the other joints between the rear fender panel F and roof panel L were soldered 8. However, although the positioning accuracy at the spot welded parts was good, the work was difficult at the 8 soldered parts. Since it has to be done on a vertical surface, the solvent tends to run off and skill is required.In addition, the rear fender panel F and roof panel L must be aligned on the side of the vehicle body, that is, on the vertical surface of the rear fender panel F. In addition, the rear end portion Lr of the roof panel L is required to be formed with high precision, making the forming operation complicated.

Furthermore, in the case of the above-mentioned conventional vehicle body structure,
Since the overlapping area between the rear fender panel F and the roof panel L is very large, there is also a problem in that the weight of the vehicle increases.

This invention was devised in light of the current situation, and its purpose is to provide a vehicle body structure which reduces the vehicle weight and facilitates the fitting and soldering operations of the roof panel and rear fender panel, particularly in automobiles in which an opera window mounting opening is formed in the rear fender panel and the front end of the rear fender panel is welded to the rear end of the side roof rail which terminates forward of the mounting opening.

In order to achieve this purpose, in this invention, a mounting opening for an opera window is formed in the rear fender panel, and the front end of the rear fender panel is provided with a rear end of a side roof rail that ends in front of the mounting opening. The upper end of the rear fender panel of the vehicle body structure, which is welded and fixed to the vehicle body structure, is bent toward the roof panel to form a roof surface, and the rear end corner of the roof panel is connected to the mounting opening in the longitudinal direction of the vehicle body. A notch is formed by cutting from between the front edge of the rear fender panel and the front end of the rear fender panel to the end of the roof panel with a width corresponding to the width of the roof surface in the width direction, and the roof surface of the rear fender panel is It is joined to the roof panel at the periphery of the notch so as to be flush with the roof panel.

Hereinafter, this invention will be explained in detail based on the embodiments shown in FIGS. 4 to 7.

4 to 6 show a first embodiment of this invention. In the drawings, parts that are the same as those in the prior art are designated by the same reference numerals.

In this example, the rear fender panel F
A mounting opening 6 for an opera window is formed in the opening 6.
It is configured such that an opera window can be fixed to the peripheral flange 1 of this mounting opening 6. The upper end of this rear fender panel F is bent and extended toward the roof panel,
The extended horizontal surface portion forms a roof surface portion 10.

Rear fender panel F formed in this way
The front end Ff of the rear fender panel F overlaps with the terminal end 30 of the side roof rail 3 and is fixed by welding, and the rear upper end of the rear fender panel F
Fr is superimposed on the rear roof rail 4 and fixed by welding. And the above side roof rail 3
The terminal end 30 ends in front of the vehicle body from the front edge 6a of the opera window mounting opening 6 formed in the rear fender panel F.

Further, a notch 11 is formed at the rear end corner of the roof panel L, and this notch 11 is located at the front edge 6a of the mounting opening 6 in the vehicle front direction x.
and the front end Ff of the rear fender panel F to the terminal end Le of the roof panel L, in the vehicle width direction y, a notch is formed with a width corresponding to the width l of the roof surface portion 10 of the rear fender panel F. There is. Furthermore, as mentioned above, there is a notch 1 in the roof panel L.
1, the end of the roof drip 12 is
It ends between the front edge 6a of the mounting opening 6 and the front edge Ff of the rear fender panel F, but the rainwater etc. flowing down from the roof drip 12 flows between the front edge Fm of the rear fender panel F and this front edge.
It is configured to flow down from between the rear edge of the door (not shown) facing Fm.

When joining the roof panel L and rear fender panel F configured in this manner, a step portion 13 corresponding to the wall thickness of the roof panel L is formed on the roof surface portion 10 of the rear fender panel F. Roof surface part 10 of rear fender panel F
is soldered 8 at the periphery of the notch 11 of the roof panel L so as to be flush with the roof panel L. As can be understood from FIG. 6, the upper rail 4a of the rear roof rail 4 is welded and fixed to the passenger compartment side joining flange 5 between the rear fender panel F and the inside panel 2.
The lower rail 4b is welded and fixed to the inside panel 2 via a bracket 9. Therefore, in this embodiment, there is no need to impurse the rear end of the roof panel L, so the forming operation is easy, and the vertical surface of the rear end of the roof panel L can be formed very small. Therefore, most of the soldering work can be done on a horizontal surface. Furthermore, since the overlapping area between the rear fender panel F and the roof panel L is small, the weight of the vehicle body can be reduced.

FIG. 7 shows a second embodiment of this invention. In this embodiment, unlike the first embodiment, the upper rail 4a of the rear roof rail 4 is Using the stepped portion 5a of the supporting interior side joining flange 5, the roof surface portion 10 of the rear fender panel F is brazed 8 at the periphery of the cutout portion 11 of the roof panel L so as to be flush with the roof panel L; Other than facilitating the molding workability of the rear fender panel, the other configurations and functions are exactly the same as those of the first embodiment described above, so detailed explanation thereof will be omitted here.

Since this invention includes the above-mentioned configuration, the roof panel has good formability and the weight of the vehicle can be reduced by the amount of the notch in the roof panel.In addition, since the vertical surface portion of the rear end of the roof panel is notched, Most of the face-to-face matching and brazing work between the rear fender panel and the roof panel can be performed on a horizontal plane, which makes the work extremely easy.
