It can be appreciated that in the present utility model, the driving motor can be rotated clockwise or counterclockwise to ensure that the door lock can automatically open and close the door regardless of whether it is installed at the left side (left door opening) or the right side (right door opening) of the door leaf. The door lock can be arranged in a way that the door is opened left when the driving motor drives the second gear to rotate clockwise to close the lock, and the door is opened right when the driving motor drives the second gear to rotate anticlockwise to close the lock, namely, the direction of clockwise rotation of the driving motor when the door lock is arranged on the left side of the door leaf or the anticlockwise rotation direction of the driving motor when the door lock is arranged on the right side of the door leaf is the closing direction.

In the novel intelligent door lock, the working principle of the driving device switch lock is as follows:

1. the closing process acts:

when the driving motor drives the second gear to rotate towards the locking direction, no matter whether the optocoupler sensor is sensed, from the moment that the magnetic column is detected to trigger the Hall sensor 363 and leave the position of the Hall sensor 363, the detection of whether the second optocoupler sensor 362 is sensed (namely, the baffle is inserted into the second optocoupler sensor 362), if the second optocoupler sensor 362 is sensed to be triggered, the judgment that the lock tongue stretches out, the driving motor immediately stops the movement in the direction and immediately rotates reversely, the moment that the second optocoupler sensor 362 is not sensed is detected, the detection of whether the first optocoupler sensor 361 is sensed is started, and if the first optocoupler sensor 361 is sensed, the driving motor stops moving, and the locking action is completed.

2. The unlocking process acts:

the driving motor drives the second gear to rotate towards the unlocking direction, no matter whether the optical coupler sensor is sensed, from the moment of detecting the second optical coupler sensor 362, whether the Hall sensor 363 is sensed (the magnetic column triggers the Hall sensor 363 to be the Hall sensor 363 is sensed), if the Hall sensor 363 is sensed, the bolt is judged to retract, the driving motor immediately stops acting and immediately starts to rotate reversely, when the first optical coupler sensor 361 is not sensed, the second optical coupler sensor 362 starts to detect whether the second optical coupler sensor 362 is sensed, the driving motor stops moving when the second optical coupler sensor 362 senses, and the unlocking process is completed.

3. Locked-rotor operation logic in the switching and locking process:

after the Hall sensor 363 leaves the lock, but when the first optical coupler sensor 361 is not detected to be sensed, the driving motor is judged to be locked, the driving motor stops moving, the novel intelligent door lock outputs an audible alarm of failure in locking, and then the driving motor rotates reversely to execute unlocking action. If the hall sensor 363 is always triggered without disconnection (i.e., the magnetic pole does not move and does not displace relative to the hall sensor 363), the unlocking action is not performed, and an audible alarm of failure in locking is directly output.

When unlocking is executed, after the first optical coupler sensor 361 is detected to be not separated by induction, but the blocking of the driving motor is encountered when the Hall sensor 363 is detected to be induced, the driving motor stops moving, the novel intelligent door lock outputs an audible alarm of failure in unlocking, and then the driving motor rotates reversely to execute locking action. If the first optocoupler sensor 361 is always sensed to be not separated during unlocking, the locking action is not executed, and an audible alarm of failure of unlocking is directly output.

The foregoing is only a partial embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that modifications and adaptations can be made without departing from the principles of the present utility model, and such modifications and adaptations are intended to be comprehended within the scope of the present utility model.
