DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling a resin door such that an outer surface of a sash portion of the resin door is continuous with an outer surface of a roof panel.

[0002]

2. Description of the Related Art Generally, doors for vehicles include those made of a steel plate and those made of a resin. Such a door is to be assembled to a vehicle body in a vehicle body assembling process. In the assembled state, a continuous feeling is provided without a step or a gap between the outer surface of the vehicle body and the outer surface of the door sash portion. Therefore, it is necessary to improve the appearance quality and reduce wind noise during traveling.

However, since it is difficult to prevent the occurrence of an error in assembling the vehicle body, an error in forming the door, and the like, the alignment is adjusted after the door is mounted on the vehicle body.

[0004] In the case of a steel plate door, when a step or a gap is formed, an operator applies an external force to the sash portion to perform plastic deformation to adjust.

[0005]

However, plastic doors are less likely to be plastically deformed than steel doors. Therefore, even if an operator applies an external force to the sash and deforms the sash, the door becomes elastic. Therefore, it was difficult to adjust the position as in the case of a steel door.

Accordingly, an object of the present invention is to provide a method of assembling a resin door which can be adjusted so that a step or a gap is not formed between an outer surface of a vehicle body and the like and an outer surface of a sash portion of the resin door. And

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and the outer surface of a sash portion of a resin door coincides with the final mating surface extending from the outer surface of the roof panel to the door side. In the method of assembling the resin door, when the resin door attached to the vehicle body is closed, it is set in advance so that the outer surface of the sash portion of the resin door is located on the vehicle inner side from the final mating surface. After finishing the coating, the resin door is closed, and the outer surface of the sash portion is finally aligned by pressing the sash portion to the outside of the vehicle with a spacer interposed between the sash portion and the vehicle body to deform the sash portion. The sash portion is plastically deformed so that the outer surface of the sash portion matches the final mating surface according to the baking temperature when the paint is baked.

[0008]

According to this means, the sash portion of the resin door can be adjusted so as to coincide with the final mating surface by plastically deforming the sash portion using the temperature at the time of painting and baking. Accordingly, it is possible to prevent a step or the like from being generated between the outer surface of the roof panel and the outer surface of the sash portion, to secure the appearance quality, and to prevent the generation of wind noise and the like.

In addition, the adjustment is performed by attaching the spacers and tightening the resin door, and then performing baking. Therefore, the adjustment can be performed by a simple operation without skill.

As shown in FIG. 3, the sash portion 12 has an inner sash portion 13 and an outer sash portion 14, and the inner sash portion 13 is formed with a bulging portion 13a projecting toward the vehicle interior. A vertical portion 13b which is substantially vertically lowered is formed in a part of the portion 13a.

The sash portion 12 is designed such that when the outer surface 12c of the sash portion 12 closes the resin door 10, the sash portion 12 enters a predetermined distance L from the outer surface 15a of the roof panel 15 to the inner side of the final mating surface 16 continuing to the door side. Have been.

On the other hand, the right end side of the roof panel 15 of the vehicle body 11 assembled in the main body process in FIG.
A hanging portion 15b formed by bending downward and a flange 15c extending horizontally outward from the hanging portion 15b are continuously formed.
Is fixed to the connection portion 17a. The fixing portion 17b of the drip channel 17 is fixed to the outer panel 18a of the roof side rail 18. Reference numeral 18b is an inner panel.

Then, the resin door 10 is attached to the vehicle body 11 and then sent to a painting step. In this painting step, first, painting (undercoat) for the purpose of rust prevention is performed. This painting is performed with the door 10 opened.

Next, as shown in FIG.
Then, the spacer 20 is attached to the connection portion 17a to perform intermediate coating. The spacers 20 are attached to, for example, three places as shown in FIG.

The spacer 20 is provided on the inner sash 1
Abutment portion 21 that abuts on vertical portion 13b of third bulging portion 13a
And a holding portion 22, 23 for holding the flange 15 c of the roof panel 15 and the connection portion 17 a of the connection member 17, and the tip 22 a of the holding portion 22 is
Is brought into contact with the hanging part 15b of the head.

Then, an intermediate coating and a top coating are performed. Thereafter, baking is performed with the door 10 closed.

When the door 10 is closed, the spacer 20
The contact portion 21 of the sash portion 12 is pressed against the vertical portion 13b of the sash portion 12 so that the sash portion 12 is pressed and deformed to the outside of the vehicle, and the outer surface 12c of the sash portion 12 matches the final mating surface 16. Can be

In other words, the size, reference, and the like of the spacer 20 are set so that they can be matched.

That is, the outer surface 15 of the roof panel 15
The hanging part 15b which is continuous in the vertical direction with a constant bending angle α with respect to a is used as a reference. And it is set to a predetermined shape in advance (can be molded with high precision by injection molding)
The spacer 20 is attached to the tip part 2 at the hanging part 15b (reference).

Although a portion where no painting is performed occurs on a, the weather strip 30 is attached to the flange 15c and the connecting portion 17a, so that the portion is covered, so that there is no problem.

In the above embodiment, plastic deformation of the resin door 10 is performed by baking a top coat, but it may be performed by baking an intermediate coat.

[0027]

As described above, according to the present invention, when the resin door attached to the vehicle body is closed, the outer surface of the sash portion of the resin door is located on the vehicle inner side from the final mating surface. After the coating is completed, the resin door is closed, and the sash is deformed by pressing the sash to the outside of the vehicle with a spacer interposed between the sash and the roof panel. Since the outer surface of the portion is made to coincide with the final mating surface, and at the time of baking the paint, the resin door is plastically deformed in a state where the outer surface of the sash portion is made to coincide with the final mating surface by the baking temperature. It is possible to prevent a step or a gap from being generated between the outer surface of the vehicle body and the outer surface of the sash portion. Further, the outer surface of the sash portion can be made to coincide with the final mating surface only by attaching the spacer and closing the resin door, and the operation is extremely simple without skill, and can be performed in a short time. Therefore, the working efficiency can be improved, which is a practically useful effect.
