Description

[Detailed explanation of the idea] The present invention relates to an automobile door.

Conventionally, as shown in FIG. 1, FIG. 2, and FIG. 3, the sash 3 of an automobile door is formed in a U-shaped cross section, and the outer leg of the sash is attached to the inner bent portion of the door outer panel 1 at the upper end. It was fixed by brazing on the outside of the edge 4 and spot welding the bottom of the sash to the door inner panel 2 at the welding part 5.

However, since the brazed portion is exposed, even if it is painted, that portion will swell, which is unfavorable in terms of appearance.

In particular, rust is likely to occur on brazed parts due to direct contact with rainwater (
However, due to rust, the appearance was significantly inferior.

The present invention was made to solve the problems of the conventional example, and the bottom part of the sash formed in a U-shaped cross section is connected to the door inner panel, and the outer leg part of the sash is connected to the door outer panel. In the automobile door connected to the inner bending part, the inner bending part of the door outer panel has a
An automobile door characterized in that a convex portion protruding toward the sash leg is formed at a position a predetermined distance below the upper end edge, and the convex portion and the sash are brazed on the inside of the door outer panel. This is a summary.

According to the above configuration, since the brazing part is hidden inside the door, rust is unlikely to occur, and even if rust occurs, it is effectively prevented from rising to the top surface of the door outer panel. This can be prevented and the appearance can be improved.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 4 to 7.

In the automobile door of the present invention shown in FIGS. 4 and 5, 1 is a door outer panel, 2 is a door inner panel, and 3 is a sash having a U-shaped cross section.

A convex portion 6 is formed on the inner bent portion of the door outer panel 1 at a position a predetermined distance below the upper edge, and protrudes toward the inner side, that is, toward the outer leg portion of the sash 30.

As clearly shown in FIGS. 5 and 6, this convex portion 6 is
When the door outer panel 1 is press-molded, it is integrally formed with the panel itself.

Of course, instead of integrally molding the convex part 6, by spot welding a separate member 8 having a cross-sectional shape as shown in FIG.
Convex portions 6 may also be formed.

The bottom of the sash 3 is spot-welded to the door inner panel 2 at the welding portion 5, and the joint portion of the outer leg of the sash 30 and the convex portion 6 is welded along the vertical edge of the leg. It is fixed by brazing with the brazing part 7.

If necessary, by further brazing the joints of the legs of the sash 3 and the upper edge of the convex portion 6, the length of the brazing material and the brazing area will increase, increasing the mounting strength of the sash 3. I can do it.

As described above, according to the present invention, since the brazed portion 7 is hidden inside the door, rust is unlikely to occur, and even if rust occurs,
Since a gap is provided between the upper edge of the door outer panel 1 and the sash 3, rust generated in the brazed portion 7 can be effectively prevented from rising to the upper end surface of the door outer panel 1. This has the effect of providing an excellent appearance.

In addition, by filling the gap with rubber or the like, or by extending the window glass weather strip that is usually attached to the door and closing the gap, the brazed part I can be sealed and rust can be prevented. This has the effect of not only preventing this, but also improving the appearance.

Furthermore, in the past, the brazing part was on the outside of the door outer panel 1, so the brazing had to be done carefully and took a lot of man-hours, but in this invention, since it is on the inside, it can be brazed normally, which also saves man-hours. effective.
