Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding door for a vehicle that enables an electrical device provided on the body side of an automobile and an electrical device provided inside the sliding door to be electrically connected to each other when necessary. The present invention relates to a power supply device.

The following description will be made by taking an automobile as an example of the vehicle.

BACKGROUND ART In recent years, automatic operation or remote control of various parts of an automobile from the driver's seat or the like has been promoted. As part of this effort, it is being considered to automatically open and close sliding doors that are slidably disposed on the sides of automobiles. It is necessary to release the door holding device that prevents the sliding door from closing due to its own weight before the sliding door closes.

This kind of release operation of the door lock and the release operation of the fully open position holding device of the door is normally performed by operating an actuator consisting of an electric device such as a motor or solenoid installed inside the sliding door. In order to operate the actuator, power must be supplied to the actuator from the vehicle body.

However, in the case of a sliding door, since the entire door is slidably displaced relative to the vehicle body, it is not possible to connect the electric device inside the sliding door and the power supply on the vehicle body side using a simple conductive wire.

Therefore, as the sliding door opens and closes,
A method of supplying power to the electrical equipment inside the sliding door using a flexible conductor wire that is contracted in a meandering manner or wound around a drum has been considered, but according to this method, However, when used for a long period of time, there is a risk that the conductor wires may break, and the entire device becomes larger.

An object of the present invention is to provide a power supply device for a sliding door for a vehicle that eliminates such drawbacks.

In the present invention, the electrical device installed in the sliding door needs to be operated only when the sliding door is in the closed position or in the fully open position, and the opening/closing operation is Focusing on the fact that there is almost no need for activation during the process, two pairs of connectors were installed on the vehicle body side and the sliding door side, respectively, so that they make electrical contact when the sliding door is closed and when the door is opened. These connectors allow electrical power to be supplied to electrical devices installed inside the sliding door when the sliding door is closed and opened.
