[0025] Please also refer to Figure 4 and Figure 5 , the basic principle of the smart lock 100 provided by this application in the mechanical unlocking state is summarized as follows:

[0026] When the intelligent lock 100 is in the locked state, the teeth 1331 on the lock rod 133 are engaged with the tooth grooves 3311 provided on the slider 331, and the first part 10 can only move relatively closer to the second part 30 and cannot move away from the second part 30;

[0027] The user opens the face cover 17, inserts the mechanical key into the lock head 131, and rotates the mechanical key. The lock rod 133 and the lock rod sleeve 1131 rotate relative to the slider 331, so that the teeth 1331 are separated from the tooth grooves 3311;

[0028] The pressing rod spring 155 pushes the pressing rod 153, which causes the pressing rod 153 to push the second rubber cap 315, forcing the first part 10 to move away from the second part 30, and finally unlocking the lock.

[0029] Please also refer to Figure 4 and Figure 6 , the basic principle of the intelligent lock 100 provided in this application in the fingerprint unlocking state is summarized as follows:

[0030] When the intelligent lock 100 is in the locked state, the teeth 1331 on the lock rod 133 are engaged with the tooth grooves 3311 provided on the slider 331, and the first part 10 can only move relatively closer to the second part 30 and cannot move away from the second part 30;

[0031] The user places a finger against the fingerprint head 351 and checks the fingerprint operation status through the light 352. After successful unlocking, the fingerprint recognition component 35 controls the motor 3351 to rotate through the PCB board 37;

[0032] The motor 3351 drives the eccentric wheel 3353 to rotate, and the eccentric wheel 3353 pushes the slider 331 to slide away from the lock rod 133;

[0033] The pressing rod spring 155 pushes the pressing rod 153, which causes the pressing rod 153 to push the second rubber cap 315, forcing the first part 10 to move away from the second part 30, and finally unlocking the lock;

[0034] The eccentric wheel 3353 rotates back to the initial state and stops, and the slider spring 333 pushes the slider 331 back to the initial position, waiting to cooperate with the lock rod 153 next time to lock the door.

[0035] Compared with the prior art, the intelligent lock 100 provided by the present utility model can simultaneously achieve mechanical control and fingerprint control for unlocking through the cooperation of the lock core assembly 13, the lock sleeve assembly 33, and the fingerprint recognition assembly 35. Moreover, the fingerprint recognition assembly 35 is connected to the lock sleeve assembly 33 to control the connection state between the lock sleeve assembly 33 and the lock core assembly 13, thereby controlling the connection state between the first part 10 and the second part 30. Without an additional control structure, the volume of the intelligent lock 100 is reduced, making it more convenient for installation and use.

[0036] In addition, the first part 10 is arranged on the face cover 17, which can protect the lock head 131, preventing dust, water, etc. from entering the lock head 131, thereby extending the service life of the intelligent lock 100. In the second part 30, a light 352 is arranged around the fingerprint head 351, which can effectively provide illumination and facilitate the user to observe the state of fingerprint operation.

[0037] The above are only the embodiments of the present utility model. It should be noted here that for those of ordinary skill in the art, without departing from the creative concept of the present utility model, improvements can still be made, but these all fall within the protection scope of the present utility model.
