OPENING AND CLOSING APPARATUS WITH LOCK

摘要

An opening and closing apparatus with a lock that is provided is capable of safely and promptly closing a sliding door, and also easily performing unlocking with a simple configuration. In an opening and closing apparatus with a lock for opening and closing sliding doors that are provided with elastic members at their door leading ends, output of an electric motor is transmitted to a rack-and-pinion mechanism or a lock mechanism. A control unit controls the electric motor such that a closing operation is performed, the closing operation operates the rack-and-pinion mechanism so as to move the sliding doors to a fully closed position and then displacing a link mechanism in a lock mechanism from an unlocking position to a locking position. Furthermore, the control unit controls the electric motor so as to reduce the output of the electric motor at a predetermined intermediate time point during the closing operation.

1. An opening and closing apparatus with a lock for opening and closing a sliding door that is installed at an entrance of a vehicle and is provided with an elastic member at its door leading end, the opening and closing apparatus with a lock comprising:
an actuator; a moving mechanism for moving the sliding door in a predetermined opening direction and closing direction, using output of the actuator; a lock mechanism that operates using output of the actuator and is capable of restricting movement of the sliding door in the opening direction when the sliding door is at a fully closed position; and a control unit for controlling the actuator, wherein the lock mechanism includes an engaging member capable of engaging with a lock member capable of integrally moving with the sliding door, so as to restrict movement of the lock member in the opening direction, and a restricting member capable of being displaced between a locking position for restricting displacement of the engaging member when engaging with the lock member and an unlocking position for allowing displacement of the engaging member, with an operation of the actuator, and the control unit controls the actuator such that a closing operation is performed, the closing operation serving as an operation of operating the moving mechanism so as to move the sliding door along the closing direction to the fully closed position and then displacing the restricting member from the unlocking position to the locking position, and, at a predetermined intermediate time point during the closing operation, controls the actuator so as to reduce the output of the actuator from a predetermined first driving force to a second driving force.
