[0054] As Figure 1 The clutch module further comprises a reversing shaft 90 and a connecting rod 100. Figures 5 to 6 The reversing shaft 90 is rotatably connected with the clutch sleeve 30 and can rotate synchronously with the clutch sleeve 30, one end of the connecting rod 100 is connected with the reversing shaft 90, and the other end is connected with the door lock body, thereby driving the middle structure of the door lock body to be unlocked.

[0055] The technical scheme of the utility model sets the clutch module in the door lock, sets the connecting shaft 10 in the clutch module, and the connecting shaft 10 is connected with the lock cylinder 170 in the lock hole of the door lock handle.

[0056] This utility model's technical solution incorporates a mechanical clutch assembly and a motor clutch assembly within the clutch module. The mechanical clutch assembly includes a first clutch pin 20, movably disposed within a first mounting hole 12. The motor clutch assembly includes a second clutch pin 40, disposed within a second mounting hole 13. A clutch sleeve 30 is rotatably connected to a connecting shaft 10. The clutch sleeve 30 has a first groove 31 and a second groove 32. A first part 21 extends from the first mounting hole 12 into the first groove 31 to mechanically unlock the door lock, and a third part 41 extends from the second mounting hole 13 into the second groove 32 to motorly unlock the door lock. This utility model's technical solution facilitates the implementation of both mechanical and motor-driven unlocking modes, which are independent and do not interfere with each other. The clutch module can perform emergency mechanical locking and motor locking without relying on the lock body of the smart door lock, which is beneficial for realizing the emergency mechanical unlocking function of the clutch module and is also compatible with most door lock bodies.

[0057] The following describes each unlocking and locking state of the clutch module.

[0058] like Figure 7 As shown, when the motor is unlocked, the motor unlocking module 160 is activated, the rotation output shaft of the motor unlocking module 160 retracts, and the motor unlocking pin 70 moves. Under the elastic action of the elastic element 60, the third part 41 extends into the second slot 32 of the clutch sleeve 30. The clutch sleeve 30 is connected to the connecting shaft 10 through the second clutch pin 40, and the clutch sleeve 30 can drive the connecting shaft 10 to rotate synchronously. Under the action of the second clutch pin 40, the clutch sleeve 30 rotates synchronously with the door lock handle, thereby driving the reversing shaft 90 and the connecting rod 100 to realize the motor unlocking operation.

[0059] like Figure 7 As shown, when the motor is locked, the motor unlocking module 160 is activated. The rotation output shaft of the motor unlocking module 160 extends, abutting against and pushing the motor unlocking pin 70 to move. Under the elastic action of the elastic element 60, the third part 41 retracts from the second slot 32 into the second mounting hole 13 of the connecting shaft 10. The connection between the clutch sleeve 30 and the connecting shaft 10 via the second clutch pin 40 is broken, and the connecting shaft 10 and the clutch sleeve 30 cannot rotate synchronously. When the door lock handle is turned, the clutch sleeve 30, the reversing shaft 90, or the connecting rod 100 will not be driven, thus achieving the effect of motor locking.

[0060] In the emergency mechanical unlocking, the unlocking key is inserted into the lock hole, and the unlocking key is rotated to drive the lock core 170, the lock core connecting shaft 180 and the unlocking shaft 50 in turn. Since the third groove 51 of the unlocking shaft 50 rotates, the first clutch pin 20 is moved away from the third groove 51, and the first clutch pin 20 cannot be retracted, so that the first part 21 is connected between the clutch sleeve 30 and the connecting shaft 10. At this time, rotating the door lock handle can drive the connecting shaft 10, the clutch sleeve 30 and the reversing shaft 90 to rotate synchronously, and the emergency mechanical unlocking operation is realized.

[0061] In the emergency locking, the first clutch pin 20 is located in the third groove 51, the first clutch pin 20 is in the retracted position, the connection between the clutch sleeve 30 and the connecting shaft 10 through the first clutch pin 20 is disconnected, and the connecting shaft 10 and the clutch sleeve 30 cannot be rotated synchronously.
