Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an automobile door structure.

(Prior art and its problems) Generally, the door of an automobile is connected to the vehicle body using a hinge, as seen in Japanese Patent Publication No. 60-59101.

Incidentally, in recent years, due to the demand for reducing the weight of car bodies, consideration has begun to be given to using plastic for car bodies.

However, if the door is made of plastic, the hinge joint may deform over time and the joint with the hinge may become loose.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an automobile door structure in which the connection with the hinge does not loosen over time when the door is made of plastic.

(Means and effects for solving the problems) The present invention is based on an automobile door structure in which a vehicle body and a door are connected by a hinge, and the hinge is bolted to the door.
The door includes a metal skeleton, and an inner panel and an outer panel assembled with the skeleton interposed therebetween.

At least the inner panel of the inner panel and the outer panel is made of plastic, and the inner panel extends to a joint portion with the hinge, and a through hole is provided in the joint portion.

A metal collar integrated with the hinge is disposed in the through hole, and the hinge and the skeleton are bolted together via the collar.

With this configuration, the hinge and metal skeleton are tightened by the port with the metal collar sandwiched between them, without directly sandwiching the plastic inner panel, which prevents the port from loosening due to deformation of the plastic over time. will not occur.

Temporary attachment of the outer panel The temporary attachment of the outer panel 5 in the above door building material adjustment is as follows:
As shown in FIG. 6, this is done by fitting two protrusions 65, 66 provided on the skeleton 3 at intervals in the front-rear direction with positioning holes 67, 68 provided on the outer panel 5.

Of these, the protrusion 65 and the positioning hole 67 are in a close fitting relationship. On the other hand, the other positioning six 68 is an elongated hole extending in the front-rear direction, and the width (vertical dimension) of the elongated hole 68 is the same as the outer diameter dimension of the projection 66. As a result, both positioning holes 67, 68 and both protrusions 65.
The molding error relative to 66 is absorbed. Two positioning holes 6 provided in this outer panel 5
7.68 is covered with a side protector (not shown).

After the vehicle is painted on the door assembly process paint line, the skeleton 3
is first removed from the vehicle body as shown in the figure (
The skeleton 3 is removed from the hinge 60), and the vehicle body proceeds to the body installation line, while the skeleton 3 proceeds to the door assembly line, where the door 1 is assembled.

Assembly of the door 1 is carried out in the steps shown in FIG. In this door assembly process, the upper stay 8 and the lower stay 9 are pre-assembled with the wind guide 20 (indicated as type 1 bracket in FIG. 10).
After the window regulator 19 and the like are assembled to this square bracket, the front end member 6 and the rear end member 7 are assembled (see FIG. 4).

Door interior parts such as the glass launch channel 70 shown in FIG. This is done by inserting both members 6.7 into the space from below.

After the door interior parts are assembled to the skeleton 3 in this way, the inner panel 4 is first attached to the skeleton 3.
It is assembled against. At this time, since the collar 62 interposed between the hinge 60 and the skeleton 3 is integrated with the hinge 60, the presence of the collar 62 does not hinder the assembly of the inner panel 4. The inner panel 4 and the skeleton 3 are fixed with an adhesive 80,
Thereafter, the outer panel 5 is bolted to the inner panel 4.

The door l assembled in this way is assembled by attaching the hinge 60 and the skeleton to the port 50 in the door mounting process shown in FIG.
This is done by combining using Note that the nut 51 that is screwed into the port 50 is welded to the skeleton 3 (front end member 6) in advance.

As described above, since the collar 62 is interposed between the hinge 60 and the skeleton 3, the inner panel 4 made of plastic is not directly sandwiched between the hinge 60 and the skeleton 3, and therefore the inner panel 4 Since the port 50 does not loosen due to deformation over time, and since the collar 62 is integrated with the hinge 60, there is no problem in assembling the inner panel 4, and the door mounting process can be easily completed. In this case, if there is no need to adjust the building material again due to a change of the collar 62, that is, if the collar 62 is not integrated with the hinge 60, the collar 62
A change in the construction materials will result in a situation where the building materials will have to be adjusted again.

(Effects of the Invention) As described above, according to the present invention, even if the door is made of plastic, it is possible to prevent the door from becoming loose due to deformation of the plastic over time in connection with the hinge.
