Specifically, the lock is locked in the normal state, and at this time, the first travel switch 700 is in the off state, and the latch bolt member 200 presses the second travel switch 800, that is, the second travel switch 800 is in the on state. When the controller receives an unlocking signal (code scanning or other input signal) from the outside, for example, when a user scans a two-dimensional code to request the controller to unlock the lock, the controller controls the driving part 500 to drive the rotary dial 410 and the cam 420 to rotate in the second direction, and during the rotation process, the rotary dial 410 pushes the locking part 300 to rotate so that the hook 301 moves away from the card slot 201 until the hook 301 is separated from the card slot 201; specifically, after the locking slot 201 is released, the second resilient body 220 can drive the locking tongue component 200 to make the locking slot 201 away from the hook 301, and the locking tongue plate 210 stops at the unlocking position under the torque of the second resilient body 220 and the limiting action of the second limiting portion 240 until the cam 420 presses the first travel switch 700 in the rotary toggle mechanism 400, and the rotary toggle mechanism 400 stops rotating, thereby completing the unlocking action. In this process, the cam 420 presses the first stroke switch 700 to turn on the first stroke switch 700, and then the cam 420 continues to rotate, and when the cam 420 presses the first stroke switch 700 again, that is, the first stroke switch 700 is turned on for the second time, the controller controls the driving part 500 to stop rotating. During this time, the bolt assembly 200 rotates and moves away from the second travel switch 800, and the second travel switch 800 is open, at which time the controller receives an unlock signal. The controller determines the timing of the cam stalling by adopting the number of times the first travel switch 700 is closed, and the accuracy is high.

When the lock is closed, the bolt part 200 rotates to enable the clamping groove 201 to be close to the clamping hook 301; the bolt part 200 rotates to push the locking part 300 open, so that the hook 301 is clamped into the clamping groove 201, and the bolt part 200 and the locking part 300 are matched and kept in a locking state; after the latch tongue part 200 presses the second travel switch 800 to enter the locked state, the rotary toggle mechanism 400 is rotated in the first direction to push against the locking part 300 to limit the hook 301 from moving in the direction away from the slot 201, and the rotary toggle mechanism 400 stops rotating. Specifically, the latch bolt part 200 is pressed or pushed to enable the card slot 201 to be close to the hook 301 and to be clamped and fixed by the hook 301, the second travel switch 800 is pressed in the pressing process of the latch bolt part 200, the second travel switch 800 is switched on, the controller receives a locking signal, at this time, the controller controls the driving part to drive the cam 420 to rotate for a preset time in the first direction until the rotary toggle column 410 abuts against the locking part 300 to limit the hook 301 to move in the direction away from the card slot 201, and the locking action is completed. In this embodiment, when the controller receives the lock-off signal, the cam 420 rotates in the first direction for 2 seconds to push the rotary cylinder 410 against the locking member 300.

Since the rotation of the driving member 500, such as a motor, is susceptible to voltage, there may be a certain error if a time interval is used to control the stop rotation time of the rotary toggle mechanism 400. Therefore, the driving part 500 of the present embodiment determines the locking state of the latch bolt 200 and the stroke state of the rotary toggle mechanism 400 by receiving the detection signals of the first travel switch 700 and the second travel switch 800, and then controls the forward and reverse rotation of the rotary toggle mechanism 400 and the position state of the rotary toggle mechanism 400, so as to achieve the automatic control of the switch locking process, and the control process is precise and reliable.

In the present embodiment, the driving part 500 is a reduction motor mechanism. The worm wheel, the worm and the speed change gear box attached to the speed reduction motor have a self-locking function, the self-locking capability of the rotary toggle mechanism 400 can be effectively guaranteed, and the safety protection capability of the lockset is effectively improved.
