When a lifting switch on the controller is pressed down, the lifting motor is started, and after the speed is reduced by the planetary reducer, the output shaft of the output planet carrier 3213 drives the shifting block 332 to rotate clockwise until the arc portion 3323 on the shifting block 332 contacts with the spherical steel ball 334, as shown in fig. 11.

The lifting motor continues to rotate, the spherical steel ball 334 overcomes the attraction of the magnet 335 to be separated from the magnet under the pushing of the arc portion 3323, and continues to move upwards (radially outer end) along the sliding groove 336 under the pushing of the arc portion 3323, finally, the upper half portion of the spherical steel ball 334 is clamped into the clamping groove 3331 on the inner wall of the output disc 333, and the lower half portion of the spherical steel ball 334 is located at the upper end of the arc portion 3323, as shown in fig. 12. Under the drive of the rotation of the shifting block 332, the spherical steel balls 334 drive the output disc 333 to rotate together with the shifting block 332, so that the combination of the planetary reducer and the output gearbox is realized.

When the stop switch on the controller is pressed down or the lifting switch is released, the lifting motor is controlled to rotate reversely for a period of time and then stop, the lifting motor rotates reversely to enable the shifting block 332 to rotate reversely for a certain angle, for example, rotate counterclockwise for 20-30 degrees, so that the circular arc portion 3323 is separated from the spherical steel ball 334, at this time, the thrust applied to the spherical steel ball 334 by the circular arc portion 3323 disappears, and then the spherical steel ball 334 moves (rolls) downwards along the sliding groove 336 under the action of the suction force of the magnet 335 and is finally fixed at the lower end of the sliding groove 336 by magnetic force, as shown in fig. 13. Disengagement of the planetary reducer from the output gearbox. At this time, the output tray 333 is freely rotatable, so that when the operator manually lifts or lowers the folding window, the transmission shaft 40 can drive the output gear box and the second and first output gears to rotate, without transmitting the driving force to the planetary gear reducer and the lifting motor, and the lifting or lowering can be arbitrarily manually operated.

To disengage the clutch, the time for the elevator motor to reverse can be determined based on the reduction ratio of the planetary gear set and the angle at which the paddle 332 disengages the ball 334.

In the above scheme, there are two sliding grooves 336 on the clutch plate, and two spherical steel balls 334 and two convex parts 3322 matched with the sliding grooves 336. In practical applications, the specific number is not limited to two, and may be only one, or two or more.
