The existing electric opening and closing piece driving mechanism generally comprises an electric element, a speed reducing mechanism and a transmission mechanism, wherein the speed reducing mechanism reduces the rotating speed output by a motor, and then amplifies and transmits torque to the transmission mechanism, the transmission mechanism generally adopts one of a cable driving mechanism, a chain driving mechanism and a gear rack driving mechanism, and a door or window glass is driven by a cable or a chain to reciprocate to realize opening and closing actions. An electromagnetic clutch 7 is usually arranged between the speed reducing mechanism and the transmission mechanism, see fig. 2, to ensure that manual and automatic switching is realized, generally, the electromagnetic clutch is closed, and the motor drives the transmission mechanism to operate to drive the sliding door to open and close; the electromagnetic clutch is separated, the transmission mechanism is separated from the speed reducing mechanism, the power output of the motor is cut off, and the sliding door can be manually pushed to be opened and closed at the moment. At present, this kind of actuating mechanism has the shortcoming that, reducing mechanism is because the single-end (or double-end) worm turbine mechanism that adopts the auto-lock, do not have the reversibility, lead to under the circumstances of car storage battery feed or locking, electromagnetic clutch outage actuation, because of reducing mechanism's irreversible, can lead to manual unable opening relevant equipment, there is the potential safety hazard, can cause serious consequence if the sliding door can't open under emergency, in addition, when electronic opening closed relevant equipment, because the unable reverse transmission of reducing mechanism, if artificial when attempting the process to equipment afterburning, construct the impact to the speed reducer, lead to reducing mechanism to damage very easily, the life of reducing mechanism has been reduced.
