Apparatus for automatically opening and closing pop-up door of a vehicle
First Claim
1. An automatic opening and closing apparatus of a pop-up door comprising:
- operation means, one end of which is connected to a pop-up door urged in an opening direction, for moving in a forward direction to open the door and a backward direction to close the door;
drive means, provided at an opposite end of the operation means from the pop-up door, for applying a moving force to the operation means;
clutch means for selectively connecting the drive means to the operation means and disconnecting the drive means from the operation means;
detection means for detecting a movement of the operation means when the clutch means is in a disconnected state; and
control means for setting the clutch means to a connected state when movement of the operation means is detected and actuating the drive means to move the operation means in the same direction as that in which the operation means is moving,wherein the operation means comprises a toothed cable which engages a drive gear rotated by the drive means, thus receiving a moving force.

Abstract
One end of a toothed cable is connected to a rear door of a vehicle. The toothed cable moves forward and backward, thus opening and closing the rear door. A drive motor imparts a moving force to the toothed cable. An electromagnetic clutch connects the drive motor to the toothed cable and disconnects the drive motor from the toothed cable. A speed sensor detects the movement of the toothed cable when the electromagnetic clutch is set to a disconnected state. A control unit sets the electromagnetic clutch to a connected state when the movement of the toothed cable is detected and actuates the drive motor to allow the toothed cable to move in the same direction at that in which the toothed cable is moving. When the completely opened or closed rear door is moved to some extent in a closing direction or an opening direction by an operator'"'"'s hands, the rear door is automatically closed or opened by the drive motor.
