DRIVE DEVICE FOR INNER SWINGING DOOR

The present disclosure discloses an inward-swing door driving device, including a motor, a worm wheel and worm reducer driven by the motor, a positive clutch, an unlocking cylinder and an unlocking connecting mechanism. The positive clutch includes an inner tooth, an outer tooth and an elastic element. The inner tooth is in transmission connection with the worm wheel and worm reducer, and the outer tooth is in coaxial transmission with a door shaft of an inward-swing door. The unlocking cylinder includes a cylinder push rod. One end of the unlocking connecting mechanism is in contact with the end portion of the cylinder push rod, and the other end of the unlocking connecting mechanism is connected with the inner tooth. When air is fed into the unlocking cylinder, the cylinder push rod pushes the unlocking connecting mechanism, and the unlocking connecting mechanism drives the inner tooth to mesh with the outer tooth and compress the elastic element. When the air in the unlocking cylinder is discharged, the inner tooth and the outer tooth demesh under the action of resilience force of the elastic element. The driving device of the present disclosure uses a modularization design, so that the driving device has a small number of parts, and is simple in structure, convenient to assemble, small in volume, good in applicability, more reliable in locking and good in mechanism stability.
