Specifically, when the clutch assembly 4 is connected to the output gear 51, the power of the motor 1 may be sequentially transmitted to the output gear 51 through the reduction assembly 3 and the clutch assembly 4; when the clutch assembly 4 is separated from the output gear 51, the motor 1 stops supplying power after separation, and when the output gear 51 is driven to rotate manually, the output gear 51 cannot drive other gears in the clutch assembly 4, so that the rotation force of the output gear 51 is reduced, and even if the torque and the speed applied to the output gear 51 are large, the gears cannot be damaged.

It should be noted that, since the speed reducing assembly 3 has a plurality of speed reducing gears, the position of the first duplex gear 31 in the speed reducing assembly 3 can be set according to actual requirements; preferably, the first duplex gear 31 is located at the input end of the speed reducing assembly 3, the door lock driving mechanism further comprises a first gear 2 installed at the output end of the motor 1 and meshed with the face gear 311, and the first transmission gear 312 is meshed with other speed reducing gears in the speed reducing assembly 3.

In particular, when the first duplex gear 31 is located at the input end of the speed reducing assembly 3, other speed reducing gears in the speed reducing assembly 3 may be stacked, so that the compactness of the speed reducing assembly is improved, and the volume of the speed reducing assembly is reduced.

In this embodiment, the manual unlocking or locking function can be realized by manually rotating the driving gear 6, so that the convenience of the door lock driving mechanism is improved.

When the clutch assembly 4 is separated from the output gear 51, the driving gear 6 may be prevented from driving the output duplex gear 5 to drive the internal gears of the clutch assembly 4 and the reduction assembly 3, which may increase the rotational resistance of the driving gear 6, and may also risk gear breakage.

In the present utility model, the planet gear 42 is disengaged from the output gear 51 by a motor, so that no matter in which direction the driving gear 6 drives the output gear 51 to rotate, the output gear 51 does not drive the gears in the clutch assembly 4 and the reduction assembly 3 to rotate.
