Abstract

PURPOSE:To provide an automobile door which is designed to efficiently improve a reinforcing effect by providing outer and inner reinforcing members. CONSTITUTION:In an automobile door 10 comprising an outer reinforcing member 12 fixed to an outer panel 11; and an inner reinforcing member 13 fixed to an inner panel 17, the outer reinforcing member and the inner reinforcing member 13 are securely welded to each other except a window glass elevation opening.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to automobile doors.

[0002]

5 to 9 show an example of a conventional automobile door 1. The door 1 has an outer panel 2 to which an outer reinforcement member 3 is attached, and an inner panel 4 to which an inner reinforcement member 5 is attached.

The outer reinforcement member 3 and the inner reinforcement member 5 both serve to reinforce the lateral load of the door 1. Note that FIG.
In, 6 is a hinge gusset.

[0004]

By the way, in the conventional automobile door 1 as described above, the outer reinforcement member 3 and the inner reinforcement member 5 are separately provided to the outer panel 2 and the inner panel 4, respectively. However, since the outer reinforcement member 3 and the inner reinforcement member 5 are provided, the reinforcing effect is not so high.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an automobile door capable of sufficiently enhancing the reinforcing effect by providing the outer reinforcement member and the inner reinforcement member.

In the present invention, in order to achieve the above object,
In an automobile door provided with an outer reinforcement member fixed to an outer panel and an inner reinforcement member fixed to an inner panel, the outer reinforcement member and the inner reinforcement member except for the window glass lifting opening. And are fixed to each other by welding in advance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an automobile door according to the present invention will be described below in detail with reference to the accompanying drawings. 1 to 4
Shows the automobile door 10 of the present embodiment.

The door 10 of this embodiment has a lean force member 11 for the lateral load therein. The lean force member 11 is the outer lean force member 12
And an inner lean force member 13.

The outer reinforcement member 12 and the inner reinforcement member 13 have a central portion 1 in cross section.
2a and 13a are bent into a substantially U shape, and further, both end portions 12b, 12b, 13b and 13b thereof are projected in a direction facing each other.

The outer lean force member 12 and the inner lean force member 13 are provided at both ends 12 thereof.
b, 12b, 13b, 13b are welded and fixed to each other,
Preliminarily formed as an integrated lean force member 11.

After the reinforcement member 11 is integrated, the door 1 is provided between the both ends 12b, 12b, 13b, 13b.
A window glass raising / lowering opening 14 for raising / lowering a window glass (not shown) of 0 is formed.

The lean force member 11 thus preliminarily integrated is the outer lean member 1.
The upper end portion 12c on the second side is spot-welded and fixed to the outer panel 15 of the door 10, and the lower end portion 12d thereof is adhesively fixed to the outer panel 15 with an adhesive 16.

Further, in the lean force member 11, the upper end portion 13c on the inner lean force member 13 side is the door 10.
The inner panel 17 is spot-welded and fixed, and the lower end portion 13d is spot-welded and fixed to the trim mounting surface 17a of the inner panel.

This completes the mounting of the lean force member 11 inside the door 10. In addition, in FIG. 1, 18 is a hinge gusset.

In this embodiment, by forming the window glass raising / lowering opening 14 as described above, the outer lean force member 12 and the inner lean force member 13 form a closed horizontal sectional space.

By providing such a closed cross section space, the reinforcing effect of the lean force member 11 can be sufficiently enhanced. Along with this, the work of attaching the lean force member 11 to the door 10 requires only a small number of spot welding points.

Therefore, the work of attaching the lean force member 11 to the door 10 can be performed easily and quickly, and sufficient strength can be obtained despite the small number of spot welding points.

[0018]

As described above, according to the automobile door of the present invention, the automobile door is provided with the outer reinforcement member fixed to the outer panel and the inner reinforcement member fixed to the inner panel. Since the outer reinforcement member and the inner reinforcement member are pre-welded and fixed to each other except for the window glass raising and lowering opening, the outer reinforcement member and the inner reinforcement member form a closed horizontal sectional space. Are formed, whereby the reinforcing effect of the lean force member is sufficiently enhanced.

Further, as a result, the work of attaching the lean force member to the door requires only a small number of spot welding points, so that the work of attaching the lean force member to the door can be performed easily and quickly. In addition, sufficient strength can be obtained despite the small number of spot welding points.
