DOOR OPERATING APPARATUS, ELECTROMAGNETIC CLUTCH, AND COUPLING MECHANISM
First Claim
1. A vehicle backdoor operating apparatus, comprising:
- a motor bracket that covers a driving shaft of a driving motor, and holds the driving motor to a supporting bracket;
an output shaft that is disposed from the motor bracket toward the supporting bracket so as to be orthogonal to an extending direction of the driving shaft;
a first rotational element that is linked with the driving shaft of the driving motor, and disposed on the output shaft and disposed within the motor bracket;
a second rotational element disposed between the first rotational element and the supporting bracket on the output shaft;
a clutch unit including a clutch driving section that supports a rotation of the output shaft, wherein the clutch driving section is mounted to and held by the supporting bracket, whereinwhen the first rotational element and the second rotational element are engaged by driving of the clutch driving section, a swing arm is actuated by the driving force of the driving motor,a coupling mechanism comprising;
a first member including a head portion in a spherical shape,a second member including a recessed portion that fits with the head portion, anda spacer that is provided between the first member and the second member, and generates an elastic force such at that the first member and the second member are separated from each other,wherein the coupling mechanism rotatably connects one end of the swing arm to one end of a rod which is connected to a backdoor of a vehicle, so that actuation of the swing arm by the driving motor causes the rod to open or close the backdoor of the vehicle via the coupling mechanism.

Abstract
A door operating apparatus includes a motor bracket that covers a driving shaft of a driving motor; an output shaft that is disposed from the motor bracket toward the supporting bracket so as to be orthogonal to an extending direction of the driving shaft; a first rotational element that is linked with the driving shaft, and disposed on the output shaft; a second rotational element that is linked with a door operating mechanism, and disposed between the first rotational element and the supporting bracket on the output shaft; and a clutch unit including a clutch driving section that supports a rotation of the output shaft. When the first rotational element and the second rotational element are engaged by driving of the clutch driving section, the door operating mechanism is actuated by the driving force.

5. A vehicle backdoor operating apparatus comprising:
-
an electromagnetic clutch that is disposed around a rotational shaft, and transmits a driving force of a driving motor to the rotational shaft; a rotary sensor disposed near an end portion of the rotational shaft that detects the rotating state of the rotational shaft, wherein the rotary sensor includes a sensor gear, a magnet disc plate having a magnetic strip, and a Hall element; wherein the sensor gear is provided at an end portion of the rotational shaft so that an axial center of the sensor gear and an axial center of the rotational shaft coincide, wherein the magnet disc plate is rotationally driven according to rotation of the sensor gear and an axial center of the magnet disc plate does not coincide with the sensor gear, and wherein the Hall element faces the magnetic strip of the magnetic disc;
a swing arm that is actuated by the driving force of the driving motor; anda coupling mechanism comprising; a first member including a head portion in a spherical shape, a second member including a recessed portion that fits with the head portion, and a spacer that is provided between the first member and the second member, and generates an elastic force such that the first member and the second member are separated from each other, wherein the coupling mechanism rotatably connects one end of the swing arm to one end of a rod which is connected to a backdoor of a vehicle, so that actuation of the swing arm by the driving motor causes the rod to open or close the backdoor of the vehicle via the coupling mechanism. - View Dependent Claims (6, 7)

8. A vehicle backdoor operating apparatus, comprising:
-
a rod connected to a backdoor of a vehicle; an arm having a first end for rotatably mounting on a main body of the vehicle; a first coupling mechanism for rotatably connecting a first end of the rod to the backdoor; and a second coupling mechanism for rotatably connecting a second end of the rod to a second end of the arm, wherein the rod moves the backdoor in an opening direction of the backdoor or in a closing direction of the backdoor according to a rotation of the arm, wherein the first coupling mechanism comprises; a head portion having a spherical shape formed on the door; a recessed portion formed on the first end of the rod that fits with the head portion; and a spacer that is provided between the head portion and the recessed portion, and generates an elastic force such that the head portion and the recessed portion are separated from each other, wherein the recessed portion includes an opening portion, a circumferential groove portion formed adjacent to the opening portion, a central portion formed adjacent to the circumferential groove portion, and a depth portion formed adjacent to the central portion, and wherein the depth portion has a conical recess shape, the central portion has a diameter slightly larger than the head portion, and the circumferential groove has an annular ring portion disposed therein for preventing the head portion from being removed from the recessed portion, wherein the second coupling mechanism comprises; a head portion having a spherical shape formed on the second end of the arm; a recessed portion formed on the second end of the rod that fits with the head portion; and a spacer that is provided between the head portion and the recessed portion, and generates an elastic force such that the head portion and the recessed portion are separated from each other, wherein the recessed portion includes an opening portion, a circumferential groove portion formed adjacent to the opening portion, a central portion formed adjacent to the circumferential groove portion, and a depth portion formed adjacent to the central portion, and wherein the depth portion has a conical recess shape, the central portion has a diameter slightly larger than the head portion, and the circumferential groove has an annular ring portion disposed therein for preventing the head portion from being removed from the recessed portion. - View Dependent Claims (9)
