A common relay (19), a low-speed rotation relay (20), and a high-speed rotation relay (21) are connected to the ports.

  The detection means in the present invention includes a latch detection switch (14) formed by a limit switch or the like, a release detection switch (15), and a close detection switch (16). Not. For example, a dedicated switch for detecting the standby position of the sector gear (9) may be provided separately. Further, a contactless switch such as an optical sensor may be used. In short, the configuration is not specified as long as it can detect the standby position, the release position and the close position of the sector gear (9), and the state of the latch portion (3).

  When the latch (5) moves from the open position (5A) to the half latch position (5B), the latch detection switch (14) detects the half latch state of the latch unit (3) by switching from on to off. In addition, when the latch (5) moves from the full latch position (5C) or the half latch position (5B) to the open position (5A) side, it is switched from off to on and the latch section (3) is opened. To detect.

  The release detection switch (15) is in an off state when the sector gear (9) is in the standby position, and when the sector gear (9) moves to the release position, the release detection switch (15) is switched on to detect the release position of the sector gear (9). .

  The close detection switch (16) is in an off state when the sector gear (9) is in the standby position, and when the sector gear (9) moves to the close position, the close detection switch (16) is switched on and detects the close position of the sector gear (9). .

  The standby position of the sector gear (9) is detected when both the release detection switch (15) and the close detection switch (16) are turned off.

  When the motor (7) is rotated at a low speed in one direction, the common relay (19) is energized to be turned on (state indicated by a two-dot chain line in FIG. 3). When the motor (7) is rotated at a high speed in the other direction, the low-speed rotation relay (20) is energized to turn it off (shown by a two-dot chain line in FIG. 3), and the high-speed rotation relay (21). Is turned on to turn it on (indicated by a two-dot chain line in FIG. 3).

  When the latch detection switch (14) detects the half latched state or the open state of the latch unit (3), and the release detection switch (15) detects the release position of the sector gear (9) The common relay (19) is turned on, the motor (7) is rotated in one direction at a low speed, and the opening operation detection switch (23) detects the door opening operation, and the closing detection switch (16) When the closed position of the sector gear (9) is detected, the low-speed rotation relay (20) is energized to turn off, the high-speed rotation relay (21) is turned on, and the motor (7) is rotated at high speed in the other direction. Furthermore, when both the release detection switch (15) and the close detection switch (16) are turned off, it is recognized that the sector gear (9) has returned to the standby position, and the motor (7) rotates. Control to stop

  As described above, the latch portion (3) is gently operated from the half latch state to the full latch state by rotating the motor (7) in one direction, and the latch portion (3) is quickly released by rotating in the other direction. It can be operated. Therefore, both the specifications for the closing operation and the releasing operation can be satisfied at the same time with one motor (7).

  4 to 8 are time charts showing the respective operations. FIG. 4 shows the release operation in the normal case. When the back door is in the fully closed position, when the opening operation detection switch (23) is turned on based on the door opening operation of the handle portion, at the same time, the motor (7) rotates at a high speed in the other direction. Thereby, the sector gear (9) rotates in the release direction from the standby position, and the latch portion (3) is released to open the back door.

  When the sector gear (9) moves to the release position and the release detection switch (15) switches from off to on, the motor (7) temporarily stops.

  Then, the latch detection switch (14) opens the latch portion (3) within (less than) a predetermined time (t1) from the time when the release detection switch (15) detects the release position of the sector gear (9). When the state is detected, the motor (7) is rotated in one direction at a low speed, and the sector gear (9) is returned to the standby position. When the close detection switch (16) detects the standby position of the sector gear (9) and switches from on to off, the motor (7) stops at that time.

  In the control shown in FIG. 4, when the opening operation detection switch (23) detects the door opening operation, the latch part (3) is quickly released, and then the release lever (11) is gently returned to the standby position. The operability when opening the door can be improved.

  FIG. 5 shows an abnormal operation when the back door does not open despite the opening of the handle. When the back door is in the fully closed position, when the opening operation detection switch (23) is turned on based on the door opening operation of the handle portion, at the same time, the motor (7) rotates at a high speed in the other direction. Thereby, the sector gear (9) rotates in the release direction from the standby position.

  When the sector gear (9) moves to the release position and the release detection switch (15) switches from off to on, the motor (7) temporarily stops.

  The latch detection switch (14) detects the open state of the latch section (3) within a predetermined time (t1) from when the release detection switch (15) detects the release position of the sector gear (9). Otherwise, it is assumed that an abnormality has occurred in the opening operation of the back door, and the motor (7) is rotated at a low speed in one direction to return the sector gear (9) to the standby position. When the close detection switch (16) is switched from on to off, the motor (7) stops at that time.

  In the control shown in FIG. 5, the release lever (11) can be reliably returned to the standby position when a predetermined time has elapsed even if an abnormal state occurs in which the back door does not open despite the door opening operation. it can.

  FIG. 6 shows a release operation when the latch portion (3) is suddenly displaced to the open state based on the opening operation of the handle portion. When the back door is in the fully closed position, when the opening operation detection switch (23) is turned on based on the door opening operation of the handle portion, at the same time, the motor (7) rotates at a high speed in the other direction. As a result, the sector gear (9) rotates from the standby position in the release direction, and the latch portion (3) is released.

  At this time, before the sector gear (9) reaches the release position, that is, before the release detection switch (15) switches from off to on, the latch detection switch (14) detects the open state of the latch section (3). At that time, the motor (7) is temporarily stopped and then rotated in one direction at a low speed. When the sector gear (9) is returned to the standby position and the close detection switch (16) detects the standby position of the sector gear (9), the motor (7) stops at that point.

  In the control shown in FIG. 6, even if the latch portion (3) is opened before the release lever (11) reaches the release position, the release lever (11) is reliably returned to the standby position without being moved unnecessarily. be able to.

  FIG. 7 shows a closing operation in a normal case. When the latch part (3) is in the half latched state due to the closing operation of the back door, the latch detection switch (14) is switched from on to off to detect the half latched state, and this triggers the motor (7) in one direction. It rotates at a low speed. As a result, the sector gear (9) rotates in the closing direction from the standby position, and the latch portion (3) is gently displaced from the half latch state to the full latch state.

  When the sector gear (9) is moved to the close position and the close detection switch (16) is switched from OFF to ON and the close position of the sector gear (9) is detected, the motor (7) is temporarily stopped. The sector gear (9) is quickly returned to the standby position by rotating at high speed in the other direction.

  When the release detection switch (15) is switched from on to off and the standby position of the sector gear (9) is detected, the motor (7) is stopped in response to this.

  In the control shown in FIG. 7, the back door can be moved from the half door position to the fully closed position at a moderate and safe speed, and the sector gear (9) is quickly returned to the standby position and stopped after the closing operation is completed. Can be made.

  FIG. 8 shows an operation for canceling the closing operation halfway. When the latch part (3) is in a half latch state due to the closing operation of the back door, the latch detection switch (14) is switched from on to off, and the half latch state of the latch part (3) is detected. 7) rotates slowly in one direction. As a result, the sector gear (9) rotates in the closing direction from the standby position, and the latch portion (3) is displaced from the half latch state toward the full latch state.

  At this time, when the latch part (3) is displaced from the half-latch state to the full-latch state, foreign matter is caught between the back door and the vehicle body, and the emergency opening of the back door is required. Opens the handle of the back door. As a result, the opening operation detection switch (23) is switched from OFF to ON. With this as an opportunity, the motor (7) is immediately stopped and then rotated at high speed in the other direction, and the sector gear (9) is moved past the standby position. Rotate all the way to the release position. Thereby, the latch part (3) can be quickly released via the release lever (11), and the back door can be opened immediately.

  When the latch detection switch (14) detects the open state of the latch section (3), the motor (7) is temporarily stopped and rotated in one direction at a low speed to return the sector gear (9) to the standby position. When the close detection switch (16) detects the standby position of the sector gear (9), the motor (7) stops.

  In the control shown in FIG. 8, the closing operation is canceled by opening the door during the closing operation of the latch portion (3), and the door can be opened immediately.
