Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a panel structure for a vehicle sunroof opening, and more particularly to a connection structure for a roof panel and a reinforcement panel provided at the rear edge of the sunroof opening.

[Prior Art] In recent years, a sunroof S as shown in Fig. 5 has been provided for the purpose of improving the feeling of openness in the passenger compartment. It is housed in a housing provided below the trailing edge roof. In such cases, a reinforcement panel 3 is often provided on the lower surface of the trailing edge roof to strengthen it.

As shown in FIG. 6, the roof panel has an opening edge flange 21 on the inside of the vehicle.
are folded and hemmed to cover the end face of the reinforcement panel 3, and
As shown in FIG. 7, from the left and right corners to the side edges, the opening edge flange 21 is gradually changed from horizontal to vertical, and is welded to the vertical wall of the side edge panel of the opening.

[Problems to be solved by the invention] In the above joint structure, a body sealer is applied to the tip of the opening edge flange 21 of the roof panel 2 in order to prevent rust from occurring in this part and to prevent water from entering from the joint. However, at the corner part where the opening edge flange 21 gradually changes from a horizontal position to a vertical position, the flange 21 is coated as shown in FIG.
Since the tip of the front edge is not in contact with either the reinforcement panel 3 or the opening side edge panel (not shown), body sealer cannot be applied, and there is a concern that rust may occur. In the figure, 1 is a housing panel.

The present invention solves these conventional problems by making it possible to apply body sealer to the gradually changing part of the opening corner flange of the roof panel, effectively preventing the occurrence of rust and water intrusion in this part. The purpose of the present invention is to provide a panel structure for a vehicle sunroof opening that achieves improved strength.

[Means for Solving the Problems] To explain the configuration of the present invention, the opening edge of the vehicle roof panel 2 is overlapped with the upper surface of the reinforcement panel 3 arranged at the rear edge of the vehicle sunroof opening, and the roof panel 2 is Place the opening corner flange 21 on the inside of the vehicle and insert the reinforcement panel 3.
The opening edge is hemmed and sealed, and the opening corner flange 21 is gradually changed from horizontal to vertical posture along the corner from the inner position to the outer position to form the outer edge of the opening. In the panel structure of a vehicle sunroof opening formed by joining and sealing the opening side edge panel 12, the opening edge corner portion 31 of the reinforcement panel 3 is connected to the opening corner flange 2 of the vehicle roof panel 2.
It is bent into a substantially V-shaped cross section that gradually deepens from a position corresponding to the starting point of the gradually changing part 211 of No. 1 along the gradually changing part 211, and one side 311 of the V shape toward the gradually changing part 211 is gradually changed. It is positioned along the inner surface of the portion 211 to form a closed space S having a triangular cross section between the two surfaces of the vehicle roof panel, and the other side 312 of the V shape is connected to the sloped surface of the opening side edge panel 12 at the outside edge of the opening. 121, and the surface of the one side 311 is connected to the open corner flange 2.
1 and extends from the hemming portion 211 to the opening side edge panel joint portion 213 as a continuous sealer coated surface 31a.

[Effect of the invention] According to the panel structure of the invention, the sealer application surface 3
1a allows the body sealer 4 to be applied continuously from the hemming portion 212 to the opening side edge panel joint portion 213, thereby preventing rust from occurring and water from entering the gradually changing portion 211.

The opening edge corner part 31 of the reinforcement panel 3 is formed into a V-shaped cross section, and one side 311 of the opening edge corner part 31 is positioned along the inner surface of the gradually changing part 211, and a closed space S with a triangular cross section is formed between it and the vehicle roof panel 2 surface. , the strength of the opening edge of the roof panel 2 can be improved. Further, since the tip of the side 311 is located within the closed space S, there is no need to perform rust prevention treatment on this portion.

Furthermore, the other side 31 of the V-shape of the opening edge corner portion 31
2 is closely supported on the sloped surface 121 of the opening side edge panel 12 at the outer edge of the opening, sufficient support strength can be obtained.

[Example] In FIG. 5, a sunroof S is provided in the front half of the vehicle roof, and FIG.
Shown in Figure 1.

In the figure, a reinforcement panel 3 is provided at the rear edge corner of the sunroof opening S1,
A housing panel 1 is disposed below the housing panel 1 for housing a slide roof (not shown) and an opening/closing mechanism thereof. An opening 11 constituting the sunroof opening S1 is formed in the center of the housing panel 1,
The side edges thereof are bent at right angles along vehicle roof side rails (not shown) to form side edge panels 12 that stand up.

The reinforcement panel 3 is made of a substantially L-shaped flat plate, with rib grooves 32 formed in parallel on the inner part, and the outer end thereof placed and bonded to the horizontally bent upper surface of the side edge panel 12. There is. The opening edge corner portion 31 of the reinforcement panel 3 is
It is bent into a V-shaped cross section with an opening angle that gradually becomes smaller and deeper as it goes from the inner part to the outer part.

The opening corner portion of the roof panel 2 is overlapped on the upper surface of the reinforcement panel 3, and the flange 21 formed at the corner portion is folded back horizontally on the inner side to close the corner portion 31 of the reinforcement panel 3. They are hemmed together in a sandwiching manner.
The open corner flange 21 gradually changes from a horizontal position to a vertical position as it goes outward, and is joined to the vertical surface of the side edge panel 12 at its outer end.

The opening edge corner portion 31 of the reinforcement panel 3 has an outer surface formed into a V-shaped cross section along the inner surface of the gradually changing portion 211 of the flange 21 and overlaps therewith. This state is shown in FIGS. 3 and 4, and each figure is a sectional view taken along the - line and - line in FIG. 2, respectively.

Thus, the corner portion 31 allows the gradual change portion 2 to
A sealer application surface 31a is formed between the hemming portion 212 and the joint portion 213 along the
a from the hemming part 212 to the gradual change part 2.
A continuous application of body sealer 4 can be carried out via 11 to the joint 213.

Further, as shown in FIG. 3, the opening edge corner part 31 of the reinforcement panel 3 is formed into a V-shaped cross section, and one side 311 of the opening edge corner part 31 is positioned along the inner surface of the gradually changing part 211, so that the corner part 31 of the opening edge of the reinforcement panel 3 is formed into a V-shaped cross section, and one side 311 of the opening edge corner part 31 is positioned along the inner surface of the gradually changing part 211. Since a closed space S with a triangular cross-section is formed between them, the strength of the opening edge of the roof panel 2 is improved. Since the tip of the side 311 is located within the closed space S, there is no need to perform rust prevention treatment on this portion.

Furthermore, as shown in FIGS. 3 and 4, the other side 312 of the V-shape of the opening edge corner portion 31 is closely supported on the inclined surface 121 of the opening side edge panel 12 at the outer edge of the opening, so that sufficient support strength can be obtained. is obtained.
