Description

The present invention relates to a vehicle door structure.

(Prior Art and Problems Thereof) Generally, a door of an automobile is connected to a vehicle body by using a hinge as seen in Japanese Patent Publication No. 60-59101.

By the way, recently, in response to a demand for weight reduction of a vehicle body, a plastic vehicle body has been considered.

However, when the door is made of plastic, the hinge joint portion may be deformed over time and the joint with the hinge may loosen.

Therefore, an object of the present invention is to provide a vehicle door structure in which the connection with the hinge is not loosened with time when the door is made of plastic.

(Means and Actions for Solving Problems) The present invention is premised on a vehicle door structure in which a vehicle body and a door are connected by a hinge, and the hinge is bolted to the door. Made of a skeleton and an inner panel and an outer panel assembled with the skeleton sandwiched 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 with a hinge. A through hole is provided in the connecting portion, and a metal collar integrated with the hinge is provided in the through hole, and the hinge and the skeleton are bolted through the collar. It has a structure.

With this configuration, the hinge and the metal skeleton are clamped with bolts with the metal collar sandwiched between them without directly sandwiching the plasticized inner panel, so the bolts will loosen as the plastic deforms over time. Will never occur.

(Example) Hereinafter, the Example of this invention is described based on drawing.
