Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automobile door structure, and more particularly to a side door structure in which the rigidity of a glass guide for guiding and supporting a window glass is improved.

(Prior art) For example, in the side door of an automobile such as a passenger car, a glass guide is installed upright in the door body separately from the main sash that forms the door window frame, and this glass guide guides and supports the edge of the window glass. I try to do that.

Furthermore, a door structure in which the above-mentioned main sash is not provided, and instead only a corner bracket is provided at the front end or rear end of the upper part of the door body is also widely known.

On the other hand, as shown in Japanese Utility Model Application Publication No. 56-148924, the hinge attachment part of the door is usually reinforced with a hinge reinforcement fixed to the door inner panel, thereby improving the rigidity of the front part of the door. is planned. However, in conventional door structures whose rigidity has been improved in this manner, the glass guides have been formed to be elongated to guide the window glass, resulting in relatively low rigidity. Furthermore, this glass guide, which has the shape described above, was difficult to assemble to the door body with high precision.

Furthermore, as mentioned above, in door structures in which only corner brackets are provided without a main sash, it has been recognized that the corner brackets tend to lack rigidity.

(Object of the Invention) Therefore, the present invention can improve the rigidity of the glass guide and corner bracket,
Furthermore, it is an object of the present invention to provide an automobile door structure that can improve assembly accuracy.

(Structure of the Invention) The automobile door structure of the present invention does not include a main sash, but includes a corner bracket and a glass guide as described above, and a hinge reinforcement for reinforcing the hinge mounting portion is fixed to the door inner panel. In the automobile door structure, the hinge reinforcement extends inward from the end of the door, extends into the corner bracket, and is fixed thereto,
The present invention is characterized in that a glass guide is firmly supported in the inner portion of the corner bracket of the hinge reinforcement and the lower portion of the corner bracket.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in the drawings.

1, 2 and 3 show an automobile door structure according to an embodiment of the present invention. As shown in FIG. 1, the door body 10 is formed by joining a door inner panel 11 and a door outer panel 12. This door structure is, for example, a so-called sillless door structure, in which no window frame is formed in the upper part of the door body 10, and only a corner bracket 13 is provided at the front end of the upper edge. This corner bracket 13 is fixed to the door inner panel 11 using bolts 30. As shown in FIG. 2, a glass guide 14A is erected within the door body 10 at a position slightly inward from the front end of the door body 10. This glass guide 14A is fixed to the door inner panel 11 as will be described later, and extends upward into the corner bracket 13.

As shown in FIG. 3, the front end of the window glass 15 is housed and supported within the glass guide 14A, and the window glass 15 is moved up and down by a window glass regulator 16 (see FIG. 1). When the glass guide 14A moves, the glass guide 14A moves. Note that the rear end portion of the window glass 15 is also supported by a glass guide 14B similar to the glass guide 14A so as to be vertically movable.
This glass guide 14B is fixed to the door inner panel 11 using bolts 31.

Two sets of door hinge mounting holes 17 are provided at the front end of the door body 10, and a door hinge 18 is fixed by bolts 34 passed through these door hinge mounting holes 17 (see FIG. 2). The door body 10 is rotatably attached to a door opening of an automobile via these door hinges 18. A hinge reinforcement 19 is fixed to the inside of the door inner panel 11 at the location where the upper door hinge attachment hole 17 is installed. By providing this hinge reinforcement 19, the rigidity of the door hinge mounting portion is increased. This hinge reinforcement 19 is extended to the inner side of the door body 10, that is, to the rear side, and has bulges 19a, 1 formed at the lower part of the hinge reinforcement 19.
9b is fixed to the inner surface of the door inner panel 11 by spot welding, for example. The rear end 19c of the hinge reinforcement 19 is joined to a stiffener 20 that extends from the upper edge of the door inner panel 11 to the rear end of the door body, for example, by spot welding.

The glass guide 14A is connected to the door inner panel 1 via the hinge reinforcement 19.
It is fixed at 1. That is, the glass guide 14
Mounting part 14m formed at the bottom of A (see Figure 1)
A bolt 3 is attached to the glass guide fixing portion 19d formed below the bulge portion 19b of the hinge reinforcement 19 and the door inner panel 11.
Fixed via 2. Further, in this embodiment, the hinge reinforcement 19 is extended upwardly into the corner bracket 13, and is secured to the corner bracket 1 by the bolt 33.
The corner bracket 13 is reinforced by the bolts 33, and the mounting portion 14n formed at the top of the glass guide 14A is also fixed to the hinge reinforcement 19 by the bolts 33 mentioned above. As described above, the glass guide 14A is reinforced by the hinge reinforcement 19 and is firmly fixed to the door inner panel 11.

Hinge reinforcement 19 as above
By extending it upward and fixing it to the corner bracket 13, the rigidity of the corner bracket 13 can be increased, which is very advantageous in increasing the strength of the door in the case of a door of the sillless type. Then, the glass guide 1 is installed inside the corner bracket 13.
If the glass guide 4A is fixed to the hinge reinforcement 19, the upper end portion of the glass guide 14A, which tends to bend, will be firmly reinforced.

(Effects of the Invention) As explained above in detail, in the automobile door structure of the present invention, the glass guide is reinforced with hinge reinforcement, so that
The rigidity of this glass guide is certainly increased. In particular, this reinforcement is achieved by not only fixing the glass guide to the hinge reinforcement below the corner bracket, but also fixing the glass guide to the portion of the hinge reinforcement that extends into the corner bracket. The upper end of the glass guide, which tends to bend, is also strongly reinforced.

Furthermore, in the door structure of the present invention, since the hinge reinforcement extending into the corner bracket is fixed to the corner bracket as described above, the rigidity of the corner bracket can be sufficiently increased.

Since the door hinge is used as the assembly standard when assembling the door body, the hinge reinforcement that is fixed to the mounting part of the door hinge has a high assembly accuracy. By fixing the glass guide to the reinforcement, it becomes possible to assemble the glass guide with high precision.
