A waist opening 6 is formed in the upper part of the door body 1, and the door glass 7 can move up and down through the waist opening 6. A lock hole 8 is formed on the rear end surface of the inner panel 4,
A door lock 9 is attached by a bolt 10 inside the inner panel 4 corresponding to the lock hole 8. Various rods 11 connected to a door handle (not shown) or a key cylinder are attached to the door lock 9. When the door is closed, the striker 13 provided on the front end face of the center pillar 12 passes through the lock hole 8 and the door lock 9
The door lock 9 is relatively locked in and the door lock 9 is locked.

On the other hand, on the inner panel 4 of the door body 1,
A working hole 14 is formed which is used when the door lock 9 is mounted. The working hole 14 has a flange 15 at the edge so that water that has entered through the waist opening 6 does not enter the working hole 14.
In addition, the inner panel 4 has an adhesive 17 inside the bead 16.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. The same parts as those in the prior art will be designated by the same reference numerals, and overlapping description will be omitted.

1 and 2 are views showing a first embodiment of the present invention. The inner panel 20 according to this embodiment has a large opening 21 formed in the center to facilitate work inside the door. A door lock 22 is attached to the outer side of the rear end surface of the inner panel 20 with a bolt 23. A door lock switch 24 is also attached to the door lock 22.
A rod 25 extends from the door lock switch 24 toward an inside handle (not shown). Reference numeral 26 is a bell crank, which is a connecting portion of the rod 25.

Further, front and rear and lower ends 28 of the interior material 27 mainly made of a synthetic resin material extend to the vicinity of a joint point 30 with the outer panel 29 of the inner panel 20, and through a grommet 31. It is fixed to the inner panel 20 with screws 32. Therefore, since the door lock 22 is covered with the interior material 27, the interior material 2
7 is formed with an opening 34 for receiving the striker 33, and a shape retaining member 35 is fitted into this opening 34. A weather strip 36 is provided on the end 28 of the interior material 27 to cover the end 28 of the interior material 27.

The advantages of the door structure according to this embodiment will be listed below. Improve workability of installing door locks and rods: Door lock 2
Since 2 is mounted on the outer side of the inner panel 20, the mounting workability is significantly improved as compared with the conventional case where the working holes are used to mount the inner panel 20 on the inner side. Further, since the rod 25 and the like are also provided outside the inner panel 20, the connecting work between them is facilitated. Also,
In this embodiment, a particularly small working hole is eliminated and the inner panel 20 is provided with the opening 21. Therefore, the mounting and connecting work is particularly easy.

Improvement of appearance: The door lock 22 has an interior material 2
Since it is covered with 7, it is advantageous in terms of appearance. Further, the bolts 23 for mounting the door lock 22 are not exposed to the outside, and the interior material 27 covers up to the vicinity of the joint 30 between the outer panel 29 and the inner panel 20, so that the exposed inner panel 20 is a small part. Since the end portion 28 of the interior material 27 is covered with the weather strip 36, the boundary line between the parts and the parts is reduced, and the appearance can be improved also in this respect.

Secure anti-theft property: door lock 22, rod 25
Since the interior materials 27 and the inner panel 20 are installed between the interior materials 27 and the like, they cannot be unlocked from the outside without any tampering, and the antitheft property is sufficiently ensured.

Anti-freezing of the door lock : The door lock 22 is located outside the inner panel 20, and the door lock 2
Since the weather strip 36 is located on the outer side of the vehicle than the vehicle 2, even if water enters between the inner panel 20 and the outer panel 29, it is blocked by the inner panel 20 and the invading water does not reach the door lock 22. Absent. Therefore, there is no problem such as freezing caused by such invading water hitting the door lock 22.

Improvement of weather strip attachment flexibility: Since the door lock 22 was conventionally attached to the inner side of the inner panel 20, the bolt 10 for the attachment is an obstacle (see FIG. 6 of the prior art), and the door inner 22 is attached. Although it was not possible to provide the weather strip 37 on the side, in this embodiment there is only the extended interior material 27, so that the interior side weather strip 37 can be set on this interior material 27 if desired. .. However, when the weather strip 37 on the inner side is adopted, it is necessary to extend the position of the side flange 39 of the center pillar 38 accordingly, so that in this embodiment, the side flange 39 is short and the side flange 39 of the vehicle is small. Only the weather strip 36 on the outer side that can contribute to weight reduction is adopted. Further, if the weather strip 36 on the outer side is adopted, the rear end surface of the interior material 27 and the front end surface of the center pillar 38 are not contaminated, so that the appearance is also excellent.

According door weight to this embodiment, since the formation of the opening 21 in the inner panel 20 of the door, along with working inside the door becomes easy to perform, it is possible to greatly reduce the door weight.

FIGS. 3 and 4 are views showing a second embodiment of the present invention. This embodiment provides a waterproofing alternative to conventional ceiling screens. A large notch 42 is formed from the upper side on the inner panel 41 of the door according to this embodiment, and the inner panel 41 itself has a U-shape. At the edge of the notch 42, a flange 44 is formed, which is mainly made of a synthetic resin material and is bent obliquely toward the interior material 43, as in the first embodiment. On the other hand, a continuous rib 45 having a shape corresponding to the flange 44 is formed on the corresponding surface of the interior material 43 attached to the inner panel 41. The tips of the ribs 45 are set so as to be located on the inner side of the door with respect to the ends of the flanges 44. Particularly, the ribs 45 on the lower side are in a state of being slightly inclined downward due to a drainage function described later. In FIG. 4, 46 is a pocket forming member, 47 is a rail portion, 48 is a rail bracket, 49 is an ascending / descending path of door glass, 50 is a drainage hole, and 51 is a weather strip. In addition, the interior material 4 of this example
Similar to the first embodiment, the front and rear ends 43a of the lower part 3 extend to the vicinity of the joint 60 between the inner panel 41 and the outer panel 53, and the weather strip 51 is attached so as to cover the end 43a. Has been.

The waterproof measure in this embodiment does not prevent the water W that has entered through the waist opening 52 at the upper part of the door from hitting the interior material 43 by using a sealing screen or the like as in the conventional case. Of the interior material 43, and the interior material 4
The water W that has reached 3 is fed to the inner panel 41 and the outer panel 53.
And the water is discharged to the outside of the vehicle from the drain hole 50 at the lower end of the door. Specifically, the waist opening 5
The water W that has entered from 2 passes through the notch 42 and the interior material 4
Reach the inner surface of 3. Then, the water W flows down along the inner surface of the interior material 43, but since the tips of the ribs 45 are located closer to the inside of the door than the end of the flange 44, the water W
Is guided between the inner panel 41 and the outer panel 53, and is discharged to the outside of the vehicle from the drain hole 50 at the lower end of the door. Therefore, the water W does not collect between the interior material 43 and the inner panel 41, or does not flow out from the lower end of the interior material 43 to the vehicle interior side.

As described above, according to the waterproofing measure of this embodiment, it is sufficient to simply provide the ribs 45 and the flanges 44, and the sealing scoop which is difficult to perform the adhesion work as in the conventional case, or the flange which causes an increase in the width of the door is provided. It is not necessary to provide a work hole for.

The flange 44 also contributes to improving the rigidity of the inner panel 41 in which the cutout portion 42 is formed, and the rib 4 is provided.
5 can also be used for temporary holding when attaching the interior material 43 to the inner panel 41.

Further, the interior material may be formed by combining the first embodiment and the second embodiment. In this case, a part of the rib 45 in the vertical direction other than the rib 45 on the lower side can be cut out or the like.

[0025]

The vehicle door structure according to the first aspect of the present invention is as described above, and since the door lock is provided on the outer side of the inner panel, the workability of attaching the door lock is improved. And the work of connecting rods becomes easier. Further, since this door lock is covered with the interior material and is not exposed to the outside, it is advantageous in terms of appearance. A vehicle door structure according to a second aspect of the present invention is as described above, and even when the invading water reaches the inner surface of the interior material, the water flows down along the inner surface of the interior material, Since the water is guided to the outside of the inner panel by the ribs, the invading water does not drop into the vehicle interior. As described above, the waterproofing measure according to the present invention is easy to implement because it is not necessary to provide the ribs and the flanges, and thus the workability is not deteriorated as in the conventional sealing scoon.
