DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a roof side structure and a roof side assembling method, and more particularly to a roof side structure and a roof side assembling method for mounting a roof side outer panel and a roof panel on a roof side rail in a vehicle such as an automobile. .

[0002]

2. Description of the Related Art Conventionally, in a roof side structure and a roof side assembling method in which a roof side outer panel and a roof panel are assembled to a roof side rail in a vehicle such as an automobile, the structures shown in FIGS. Are known.

As shown in FIG. 5, in this roof side structure, a bottom portion 102A of a concave portion 102 formed in a vehicle width direction outer edge of a roof panel 100 along a vehicle front-rear direction.
, A flange 100A of the roof panel 100;
The flange 104A of the roof side outer panel 104 is laser-welded, and the flange 104A of the roof side outer panel 104 and the upper wall 106 of the roof side rail 106 are laser-welded.

[0004]

However, in this roof side structure, the flange 100A of the roof panel 100, the flange 104A of the roof side outer panel 104, and the upper wall portion 106 of the roof side rail 106 are formed by ordinary laser welding. It is difficult to weld three pieces simultaneously, and as shown in FIG. 7, a convex portion is formed on a laser welded portion 110 between the flange 104A of the roof side outer panel 104 and the upper wall 106 of the roof side rail 106. Is formed, it is considered that the flange 100A of the roof panel 100 cannot be joined on the welded portion 110. That is, as shown in FIG. 6, the edge 100B of the flange 100A of the roof panel 100 is made uneven, and the roof side outer panel 10 shown in FIG.
4 and a laser weld 110 between the upper wall 106 of the roof side rail 106 and a weld 112 between the flange 100A of the roof panel 100 and the flange 104A of the roof side outer panel 104 shown in FIG.
And do not overlap each other.

As a result, in this roof side structure, as shown in FIG. 6, it is necessary to form a portion 100C where the press allowance W is narrow on the flange 100A of the roof panel 100, which makes press molding difficult. In addition, since it is necessary to apply a sealer to the edge portion 100B of the flange 100A having the uneven shape, the operation of applying the sealer becomes complicated.

As a result, it is not necessary to form the flange of the roof panel with an uneven shape unlike the conventional structure. This eliminates the need to form a narrow press allowance on the roof panel flange, which is the welded part with the roof side outer panel, and facilitates press forming, and the flange of the sealer is applied with a straight edge to form the sealer. Since the coating is easy, the productivity is improved.

According to a fourth aspect of the present invention, there is provided a roof side assembling method for welding a roof side outer panel and a roof panel, the method including: a step of welding a roof side outer panel to a roof panel; A roof side rail welding step of welding the installed extension portion and the roof side rail.

Therefore, by the roof panel welding process,
The roof side outer panel and the roof panel are welded, and the roof side rail welding process is used to weld the roof side rail to the extension portion of the roof panel that extends from the welded portion of the roof side outer panel to the outside of the vehicle. The welded portion of the roof panel with the roof side rail can be offset to the outside of the vehicle with respect to the welded portion of the roof panel with the roof side outer panel. As a result, it is not necessary to form the flange of the roof panel with an uneven shape unlike the conventional structure. For this reason, press molding is facilitated, and the edge of the flange to which the sealer is applied becomes straight, so that the sealer can be easily applied, thereby improving the productivity.
