The implementation principle of the embodiment is as follows: the user can advance USB with fingerprint data storage to through USB module 9 input fingerprint data, control circuit module 5 accessible fingerprint sensor 31 carries out identification, accomplishes follow-up operations such as unblanking.

The control circuit module 5 can determine the position of the magnetic sheet 44 by detecting the magnetic field through the hall sensor 7, thereby determining the rotation state of the handle 3. After the user finishes the door closing action, if the handle 3 does not return to the original state, the control circuit module 5 can remind the user that the door is in an unlocked state through the loudspeaker 8, so that the safety of the intelligent door lock is improved. The stirring block 4 can be matched with the fixing block 47 through the mounting block 43 to wrap the magnetic sheet 44, so that the magnetic sheet 44 is prevented from being separated from the stirring block 4 after long-time swinging, the condition that the Hall sensor 7 cannot normally recognize is caused, and the durability and the safety of the intelligent door lock are further improved.

In addition, circuit board 91 and speaker 8 on the USB module 9 are installed in same position, can the person of facilitating the use go on carrying out the overall arrangement to the inside electric wire of casing 2, improve the assembly efficiency of intelligent lock.

When the user encounters an unexpected situation and cannot open the door lock, the user can insert a corresponding key into the lock cylinder 61 and rotate the lock cylinder 61, and the lock cylinder 61 can drive the driving member 64 to rotate through the first bevel gear 62 and the second bevel gear 63, so as to open the lock tongue on the lock body 11.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
