Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle outer panel structure commonly used by vehicles of different specifications.

[0002]

2. Description of the Related Art In automobiles, it is common practice to produce vehicles of the same type but different specifications. An example of such a so-called one-box car is a case where a vehicle with a slide door provided with a slide door on a side portion of a vehicle body and a vehicle without a slide door are produced. The outer panel of the slide door used for the vehicle with the slide door and the side panel mounted on the vehicle body portion corresponding to the slide door in the vehicle without the slide door differ greatly in the coupling structure with the counterpart member. For this reason, a structure in which both are shared has not yet been attempted, and draw molding is performed using dedicated molds.

Further, in a vehicle with a sliding door, the location of the sliding door differs depending on the traffic regulations of the country concerned, and in the case of a vehicle used in a country where left-hand traffic is adopted, the sliding door is slid to the left side of the vehicle body. The door is arranged, and the side panel outer is arranged at the corresponding portion on the right side of the vehicle body. On the contrary, in a vehicle used in a country that adopts right-side traffic, a slide door is arranged on the right side of the vehicle body and a side panel outer is arranged on the left side of the vehicle body.

[0004]

As described above, conventionally, in the production of a vehicle with a sliding door and a vehicle without a sliding door, a dedicated mold for molding the door outer of the sliding door and the side panel outer is prepared in advance. Therefore, the number of required molds increases, and the mold cost becomes large. On the other hand, as described above, even in a vehicle with a slide door, the side panel outer is attached to the opposite vehicle body portion corresponding to the slide door. Therefore, it is possible to reduce the number of molds required by using this side panel outer in a vehicle without a sliding door. However, in the related art, the right side panel outer and the left side panel outer are left / right different, so it is impossible to share both side panel outers.

The same applies to the door outer panel. Since the outer panel of the sliding door arranged on the left side of the vehicle and the outer panel of the sliding door arranged on the right side are left / right different, they are commonly used. You cannot do it. Therefore, in a vehicle with a sliding door, it is also necessary to produce two types of door outer panels, one for a vehicle with the sliding door on the left side and one for a vehicle with the sliding door on the right side.
This also increases the number of required molds, resulting in a large mold cost.

The present invention has been made in view of such a conventional situation, and is used for producing a vehicle with a sliding door and a vehicle without a sliding door, or a specification vehicle in which the positions of the sliding door are different between the left and right sides of the vehicle body. It is an object of the present invention to provide an outer panel structure of an automobile that can be commonly used for the first draw type when manufacturing the vehicle.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a door outer plate of a slide door arranged in a first specification vehicle and a slide door in a second specification vehicle are provided. And a vehicle body outer panel to be mounted on a portion corresponding to the front and rear body symmetrically with respect to the center line, the door outer panel and the vehicle body outer panel are located inside the specific portion of the peripheral portion of the member. The regions have the same surface shape.

[0008]

In the above structure, since the door outer plate of the slide door and the vehicle body outer plate attached to the portion corresponding to the slide door are symmetrical with respect to the center line,
The door outer plate and the vehicle body outer plate, which are molded using the same mold, can be arranged on either side of the vehicle body. Therefore, if only a single type of mold is prepared, a door outer plate and a vehicle body outer plate that can be arranged can be formed for a specification vehicle in which the slide door and the vehicle body outer plate are on either side of the vehicle body.

Further, the door outer plate inevitably has a peculiar portion at the peripheral edge in order to be coupled with the door inner plate, and on the other hand, even in the vehicle body outer plate, it is inevitable in relation to other members in the assembled state. Have unique parts. However, since the region inside the specific portion has the same surface shape, there is no problem even if the same first draw mold is used to perform the molding in the region.
