Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a groove for an automobile door, particularly a satsureless door.

As shown in the cross-sectional shapes of FIGS. 2 to 4, in the conventional door structure, a reinforcing member 13 extending in the front-rear direction is welded to the upper edge of the inner panel 12 to form a closed section B, thereby preventing deformation of the door D. He was defending himself.

However, as is clear from the above cross-sectional shape, the reinforcing member 13 is provided over the entire length of the door D, which increases the weight of the door and the weight of the vehicle. It becomes necessary to consider reinforcement of the parts.

Furthermore, a door trim 14 is attached to the side surface of the vehicle interior of the door D, but as is clear from the cross-sectional shape in FIG. However, a large trim 14 is required, which poses problems in terms of weight and cost.

The present invention was made to eliminate the above-mentioned conventional drawbacks, and provides a door with a structure that reduces weight while maintaining the required rigidity of the door, and does not require the upper edge of the inner panel to be hidden by a trim. .

The present invention will be described in detail below based on embodiments shown in the drawings.

In Figs. 5 to 8, 1 is an outer panel of the door, and 2 is an inner panel. Flanges 1a and 2a are provided to hang downward from the upper edges of both the outer and inner panels 1 and 2. A protrusion portion 2e extending in the front-rear direction is provided by a stepped portion 2b that projects toward the inside of the vehicle interior, so that the longitudinal section of the upper part of the inner panel 2 has approximately the same shape in the front-rear direction.

Reference numeral 3a denotes a substantially U-shaped connecting member, whose respective surfaces are welded to the flange 2a1 of the inner panel 2, the rear wall 2c, and the flange 1a of the outer panel 1 after opening 6 for raising and lowering the glass of the door.

3b is the flange Ia, 2a of the opening 6 front flannel 1, 2.
and a connecting member whose respective surfaces are welded to the inner panel front wall 2d. In this embodiment, a notch 2f for raising and lowering the glass is formed in the front wall 2d, and a notch 3 is also formed in the connecting member 3b.
f is required, and in order to compensate for the decrease in strength, the connecting member 3b is
extends the joint surface with the front wall 2d toward the outer panel 1 side.

In addition, the inner wall 2g and front and rear walls 2c and 2d of the inner panel 2
and both connecting members 3a.

It is desirable that the spaces 7a, 7 and b formed by the cylindrical member 3b have a large closed cross section as long as there is no interference with internal mechanical parts.

In the drawings, reference numerals 5a and 5b denote reinforcing members for reinforcing the surfaces to which hinges (not shown) are attached, 4 a door trim, and 8 a weather strip.

Therefore, according to the above configuration, a highly rigid cross-sectional shape can be obtained in one panel by the flange 2a and the protrusion 2e on the upper edge of the inner panel 2, and the flanges of both the inner and outer panels 1 and 2 can be obtained at the front and rear of the panel. By firmly fixing 1a and 2a, door rigidity substantially equivalent to that of a reinforcing member extending substantially over the entire length of a conventional door can be obtained.

As described above, according to the present invention, instead of using a reinforcing member extending the entire length of the door, it is only necessary to connect the flanges of both the inner and outer panels at the front and rear of the opening.
A door with high rigidity can be obtained at a low price.

Furthermore, since the flange does not protrude from the upper edge of the inner panel, it is easy to cover the door trim below the step except for this part.
