[0024] In this embodiment, a driving disk upper cover 41 is installed on the top of the driving disk 4, and a semicircular annular groove 42 is provided on the surface of the driving disk upper cover 41 away from the center of the circle. A protrusion is installed on the top of the driven tooth 33, and the protrusion is slidably matched with the semicircular annular groove 42 to ensure the rotation limit of the driving disk 4 so that its rotation range is 180°.

[0025] Specifically, a spring is sleeved on the outside of the lifting column 24 , the bottom end of the spring is welded and fixed on the clutch seat 1 , and the upper end of the spring is welded and fixed on the lifting column 24 , so as to realize the resetting of the lifting column 24 .

[0026] Furthermore, a hole is provided at one end of the lifting member 23 away from the lifting column 24 , a guide column is passed through the hole, and the bottom end of the guide column is mounted on the clutch seat 1 to ensure stable lifting of the lifting member 23 .

[0027] Furthermore, the manual clutch assembly 2 includes a lock core 21, the output shaft of the lock core 21 is equipped with a rotating block 22, a lifting member 23 is arranged at the lower part of the rotating block 22, a lifting column 24 is arranged at one end of the lifting member 23, and a protruding structure is arranged on one side of the rotating block 22. The rotating block 22 rotates to drive the lifting member 23 to move downward through the protruding structure, thereby realizing the downward movement of the lifting column 24.

[0028] Furthermore, a first axial hole 333 is provided in the middle of the driven tooth 33, a second axial hole 352 is provided in the middle of the magnetic suction cup 35, the bottom of the fixed shaft 34 is fixed on the clutch seat 1, and the upper part of the fixed shaft 34 passes through the first axial hole 333 and the second axial hole 352 to ensure the stable rotation of the driven tooth 33 and the magnetic suction cup 35.

[0029] Furthermore, the lock core 21 is mounted on the driving disk 4 via a fixing frame, which facilitates the installation and fixing of the lock core 21 .

[0030] When the clutch mechanism of the smart lock of the utility model is used, first when it is necessary to manually unlock the lock, the user inserts the key into the lock cylinder 21 and rotates it, and the output shaft of the lock cylinder 21 drives the rotating block 22 to rotate. The raised structure on the rotating block 22 will support the lifting member 23 during the rotation process, causing it to move downward. The movement of the lifting member 23 then drives the lifting column 24 to move downward, realizing the unlocking state of the clutch mechanism.

[0031] When it is necessary to unlock the door electrically, the motor 31 starts after receiving the unlocking signal, and its bottom output shaft drives the driving teeth 32 to rotate. The driving teeth 32 mesh with the driven teeth 33, so the driven teeth 33 will also rotate. Two first magnetic holes 331 and two second magnetic holes 332 are provided at the bottom of the driven teeth 33, and magnets are installed inside these magnetic holes. Two third magnetic holes 351 are provided on the top of the magnetic suction cup 35, and magnets are also installed inside. The magnetism of the magnet in the first magnetic hole 331 is opposite to that of the magnet in the third magnetic hole 351, and the magnetism of the magnet in the second magnetic hole 332 is the same as that of the magnet in the third magnetic hole 351.

[0032] In the initial state, the third magnetic hole 351 corresponds to the position of the two first magnetic holes 331 and they are attracted to each other in different shapes, so the magnetic suction cup 35 is adsorbed on the lower part of the driven tooth 33, and the clutch handles the separation state. When the driven tooth 33 rotates 180° under the drive of the motor 31, the third magnetic hole 351 corresponds to the position of the two second magnetic holes 332 and they repel each other in the same way. At this time, the magnetic suction cup 35 is repelled and separated, thereby realizing the closing action of the clutch mechanism. Whether it is manual or electric, the clutch mechanism allows the lock to be opened. When locking is required, only the reverse operation is required to return the clutch mechanism to the separation state.

[0033] In addition, a driving disk upper cover 41 is installed on the top of the driving disk 4, and the semicircular ring groove provided thereon is slidably matched with the protrusion on the top of the driven gear 33 to ensure that the rotation range of the driven gear 33 is 180°, thereby achieving precise clutch control. A spring is provided on the outer sleeve of the lifting column 24 to achieve the reset function of the lifting column 24. A hole is provided at one end of the lifting member 23 away from the lifting column 24, and a guide column is inserted into the hole to ensure the stability of the lifting member 23 during the lifting process.
