TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sunroof device in which an opening formed in a roof panel is opened and closed by a sunroof glass, and more particularly to a structure of the opening of the roof panel.
[0002]
[Prior art]
2. Description of the Related Art Automobiles may be provided with a sunroof device that ventilates and illuminates the interior of a vehicle for the purpose of improving the occupant's exhilaration. As this type of sunroof device, for example, as shown in FIG. 4, a sunroof glass 52 is disposed in an opening 51 formed in a roof panel 50, and the rear portion of the sunroof glass 52 is swung up and down to open the opening 51. There is a tilt-up type that opens and closes (see, for example, Japanese Utility Model Laid-Open No. 4-14516).
[0003]
In such a sunroof device, a vertical wall portion 50a extending downward is formed at the opening edge of the roof panel 50, and the weather strip 53 mounted on the peripheral edge of the sunroof glass 52 is brought into contact with the vertical wall portion 50a. A structure is generally employed in which a gutter-shaped sunroof unit base 54 is provided below the opening edge to prevent water from entering the room.
[0004]
Further, in order to increase the strength of the opening of the roof panel 50, conventionally, a hook-shaped section having an upper side 55a along the roof panel 50 and a vertical side 55b along the vertical wall 50a is provided at the opening edge of the roof panel 50. In some cases, the reinforcement 55 is disposed, and the vertical side portion 55b and the vertical wall portion 50a are spot-welded in the horizontal direction.
[0005]
[Problems to be solved by the invention]
However, the above-described conventional opening structure has the following problems.
First, as shown in FIG. 5, since the front end portion of the roof panel 50 generally has a large curvature, in order to avoid interference with the spot gun 60, the length h of the vertical wall portion 50a is increased. It is necessary to secure a spot fee. For this reason, there is a problem that the amount of protrusion of the vertical wall portion 50a into the room becomes large, and the head clearance becomes small accordingly.
[0006]
Second, in order to avoid interference with the spot gun 60, there is a restriction that the upper side 55a of the reinforcement 55 must be shaped along the roof panel 50. The coefficient becomes small, and the strength of the opening cannot be increased.
[0007]
Third, since the spot direction of the vertical wall portion 50a is different from the vertical spot welding of other portions, it is necessary to prepare another type of spot gun, which increases the cost.
[0008]
Fourth, as shown in FIG. 4, depending on the momentum of water entering from the opening 51 at the time of tilting up, there is a possibility that the water may jump from the sunroof unit base 54 and enter the room, and in some cases, the sunshade 61 and the headlining 62 may be moved. There is a problem that the appearance becomes dirty and the appearance deteriorates.
[0009]
The present invention has been made to solve the above-mentioned conventional problems, and can secure head clearance, improve the strength of an opening, further reduce costs, and prevent water from entering a room. It is an object of the present invention to provide an opening structure of a sunroof device that can be used.
[0010]
[Means for Solving the Problems]
In the present invention, an opening which is opened and closed by a sunroof glass is formed in a roof panel, a vertical wall portion extending downward is formed at the opening edge, and an upper side portion along the roof panel is formed at an opening edge of the roof panel. A generally hook-shaped reinforcement having a vertical side along the wall is provided, and a roughly gutter-shaped sunroof unit base surrounding the lower end of the vertical wall and the vertical side is provided below the opening edge. In the opening structure of the sunroof device, at the lower end of the vertical wall portion, a flange portion extending substantially horizontally inside is bent and formed, and at the lower end of the vertical side portion, a horizontal side portion abutting on the flange portion is bent and formed, and a transverse edge portion and the flange portion is spot welded to the vertical direction, the edge of the upper side portion of the reinforcement, to form an extension extending downwardly at the outside of the sunroof unit base, thereby San It is characterized by being configured a labyrinth between-safe unit base and reinforcement.
[0012]
Operation and Effect of the Invention
According to the opening structure of the sunroof device according to the present invention, a substantially horizontally extending flange portion is formed on the vertical wall portion of the roof panel, and a horizontal side portion is formed on a vertical side portion of the reinforcement, and the horizontal side portion is formed. And the flange portion are spot-welded in the vertical direction, so that spot welding can be performed using the opening in the roof panel, and interference with the spot gun on the roof panel can be avoided. As a result, the length of the vertical wall portion can be reduced, and the head clearance can be increased accordingly. Further, since interference with the roof panel can be avoided, it is not necessary to increase the spot allowance at the flange portion, and it is possible to avoid the concern that the opening area is reduced.
[0013]
In the present invention, since spot welding can be performed using the opening of the roof panel, the spot gun does not interfere with the upper side of the reinforcement and the degree of freedom in the shape around the upper side can be improved. Thus, for example, by forming a flange extending downward on the upper side, the section modulus of the reinforcement can be increased, and the strength of the opening can be increased.
[0014]
Further, in the present invention, since the spot welding is performed in the vertical direction, the spot welding is performed in the same direction as the spot direction of other portions, the same type of spot gun can be used, and an increase in cost can be avoided.
[0015]
According to the present invention, since the flange portion that extends substantially horizontally is formed on the vertical wall portion of the roof panel, the flange portion suppresses the momentum of the water that has entered the sunroof unit base, and accordingly, entry into the room is reduced accordingly. Can be blocked. As a result, it is possible to prevent the sunshade and the head lining from being stained, and it is possible to avoid deterioration in appearance.
[0016]
In the present invention, since an extension extending downwardly outside the sunroof unit base is formed at the upper side of the reinforcement, a labyrinth structure can be formed by the sunroof unit base and the reinforcement. It is possible to improve the sealing property between the vehicle and the vehicle interior, and it is possible to more reliably prevent water from entering the vehicle interior.
