Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rear structure of a vehicle, and more particularly to a rear structure of a vehicle provided with a trough panel constituting a corner portion of a trunk room.

[Prior Art] From the viewpoint of press molding, the corner portion of the trunk room is often constructed from a trough panel that is a separate member from the quarter panel. An example thereof is shown in FIGS. 5 and 6.

In FIGS. 5 and 6, reference numeral 1 denotes a trough panel, which constitutes the right rear end corner of the vehicle trunk room. The inner edge of a quarter panel 2 that covers the trough panel 1 from the outside is joined to the trough panel 1. That is, the press-formed trough panel 1 has a flange 111 bent at the upper end of the vertical wall 11 at the outer edge and extends outward at a substantially right angle to the flange 111. The part where panel 2 protrudes (B in each figure)
In part), the inner edge flange 21 of the quarter panel 2 is joined to the upper end of the vertical wall 11 so as to cover the flange 111 (FIG. 7).

In addition, regarding the truft panel, the actual application was made in 1988.
There is issue 196966.

[Problems to be Solved by the Invention] In the conventional structure described above, the flange 111 is a molded upwardly stretched flange, while the flange 21 is a contracted flange. In this case, trough panel 1
In order to stretch the vertical wall 11 at the B portion to a large extent, it is necessary to increase the radius of curvature R of the flange 111 to prevent cracks and the like from occurring.

By the way, in order to ensure reliable waterproofness, the flange 21 needs to cover the flange 111 and join to the straight general part of the vertical wall 11 as described above, and increasing the radius of curvature R means that the flange 21 As the length D2 of the straight portion is increased, a large amount of wrinkles are generated in the flange 21 during press molding, resulting in a problem that the appearance deteriorates.

The present invention is an attempt to solve this problem, and aims to provide a vehicle rear structure that can suppress the occurrence of excessive wrinkles in the quarter panel flange joined to the trough panel.

[Means for Solving the Problems] To explain the configuration of the present invention, a trough panel 1 constituting a corner part of a trunk room of a vehicle has a partially curved outer edge formed at a substantially constant height. A flange 111 that is bent outward at a substantially right angle from the outer edge of the vertical wall 11 is provided.
The flange 111 is expanded at the curved portion of the vertical wall 11 so as to be flush with the general portion of the vertical wall 11, and the vertical wall 11 is formed at the edge of the expanded portion 111a.
Quarter panel 2 curved along the curve of the outer edge
The inner edge flange 21 of the inner edge flange 21 is joined.

[Operations and Effects] According to the present invention, since the flange 111 bent with a relatively large radius of curvature is eliminated in the expanded portion 111a, the straight portion D1 of the flange 21 of the quarter panel 2 is simply overlapped with the edge of the expanded portion. A short length is sufficient. Therefore, excess wrinkles generated on the flange 21 during press molding of the quarter panel 2 can be suppressed to a sufficiently small size, and the appearance can be improved.

In addition, by unfolding, the overall length of the general portion 11 can be increased in this part, so the elongation rate during processing and forming of the truuf panel 1 can be reduced, and there is no need to use high-quality materials with high elongation. This allows production costs to be reduced.

[Example] Hereinafter, an example of the present invention will be described focusing on the differences from the conventional example.

1 and 2, a standing wall 11 is formed at the outer end of the press-formed trough panel 1, and a flange 111 bent at a substantially right angle is formed at the upper end of the standing wall 11. The flange 111
indicates a protruding part of the quarter panel (not shown) (section B in each figure)
In this case, it is expanded upward to form an expanded portion 111a on the same surface as the general portion of the standing wall 11.

That is, after forming the flange 111 in the same way as other parts by expanding and punching with a press, it is expanded and formed by bending, as shown by the arrow in FIG. Section 111a. Then, the development part 111a
Then, the inner edge flange 21 of the quarter panel 2 is overlapped and joined (FIG. 3).

With this structure, the straight length D1 of the flange 21 of the quarter panel 2 can be shortened.

In the above embodiment, the protruding part of the quarter panel 2 was explained, but the concave part (the second part) of the quarter panel was explained.
The expanded portion 111a can be formed in the flange 111 at the portion C in the figure, and in this case as well, the inner edge flange 21 of the quarter panel (which is a stretched flange during molding) can be shortened.

Claims (1)

[Scope of utility model registration request] A trough panel constituting a corner of a trunk room of a vehicle is provided with a standing wall having a partially curved outer edge formed at a substantially constant height, and extending outward at a substantially right angle from the outer edge of the standing wall. A bending flange is formed, the flange is expanded at a curved portion of the standing wall so as to be flush with the general portion of the standing wall, and a quarter curved along the curve of the outer edge of the standing wall is formed at the edge of the expanded portion. The rear structure of a vehicle is made by joining the inner edge flanges of the panels.
