Like this, unlocking mechanism 600 makes carousel portion 304 rotate through control toggle portion 302 to drive hook portion 301 through carousel portion 304 and rotate to second position department, hook portion 301 breaks away from lock nose 200, makes the lock between hook portion 301 and the lock nose 200 open and removes the locking to lock nose 200, and the process of unblanking is more stable, high-efficient.

Optionally, the unlocking mechanism 600 comprises: a motor 601 and an eccentric 602. The eccentric 602 is connected with an output shaft of the motor 601, and the hook part 301 is shifted to the second position when the eccentric 602 rotates to the position facing the shifting part 302 at the farthest distance from the output shaft. In this way, in the unlocking process, the output shaft of the motor 601 drives the eccentric wheel 602 to rotate, after the eccentric wheel 602 rotates to the direction towards the toggle part 302 from the position farthest from the output shaft, the eccentric wheel 602 contacts with the toggle part 302 and pushes the toggle part 302, so that the toggle part 302 drives the lock catch 300 to rotate integrally, the hook part 301 on the lock catch 300 is toggled to the second position, the hook part 301 and the lock nose 200 are tripped, the lock on the lock nose 200 is released, and the unlocking action is completed.

Alternatively, the unlocking mechanism 600 is installed in the housing 100 through the motor fixing groove 800. Like this, the during operation of motor 601 can produce vibrations, fixes the vibrations that reduce motor 601 through motor fixed slot 800 to unlocking structure 600, makes the process of unblanking more stable.

Optionally, the unlocking mechanism 600 further comprises: a magnet 603 and a hall sensing element 604. The magnet 603 is arranged on the eccentric wheel 602, the hall sensing element 604 is arranged between the eccentric wheel 602 and the motor 601, and the magnet 603 and the hall sensing element 604 are on the same axis when the eccentric wheel 602 is rotated to a position farthest away from the output shaft to a position far away from the toggle part 302. Thus, after the motor 601 rotates one circle, the magnet 603 contacts the hall sensing element 604, and after the hall sensing element 604 senses a signal, the motor 601 stops rotating, and the eccentric wheel 602 also stops rotating, so that the eccentric wheel 602 is always in a position where the eccentric wheel does not interfere with the latch 300, the next stable closing of the door is ensured, and the normal locking of the door is ensured.

As shown in fig. 10-11, the housing 100 of the mechanism for locking provided by the embodiment of the present disclosure further includes: a micro switch 700. The micro switch 700 is provided in the housing 100 and senses the insertion of the lock nose 200. Thus, when lock nose 200 is inserted into housing 100 through socket 101, lock nose 200 pushes latch 500 to rotate, and rotation of latch 500 locks lock nose 200 on the one hand, and latch 500 contacts micro switch 700 on the other hand, so that the state of the door lock can be grasped by controlling the on/off of micro switch 700, and the user can operate the door lock conveniently.

Optionally, micro switch 700 is disposed on a side close to locking bolt 500 and at the same level as rotating part 503 of locking bolt 500. Thus, the microswitch 700 is arranged close to the bolt 500, so that the bolt 500 controls the on or off of the microswitch 700 by touching the microswitch 700, that is, the microswitch 700 is in an off state under the condition that the bolt 500 is in contact with the microswitch 700; when the latch tongue 500 is separated from the micro switch 700, the micro switch 700 is in an on state.

Optionally, the latch bolt 500 further comprises: a raised portion 505. The protrusion 505 is provided at a circumferential position of the rotation part 503 of the latch bolt 500 and is disposed toward the micro switch 700. In this way, by controlling the contact or separation of the protrusion 505 on the latch tongue 500 and the micro switch 700, the micro switch 700 is controlled to be turned on or off, thereby preventing the latch tongue 500 from being in contact with the micro switch 700 under the influence of vibration or impact force, and improving the accuracy of triggering the micro switch 700.

Optionally, the microswitch 700 comprises: a controller 701 and a touch pad 702. The touch piece 702 is disposed on one side of the controller 701 close to the protrusion 505, and when the latch tongue 500 is locked to the lock nose 200, the protrusion 505 and the touch piece 702 are in a contact state, and when the latch tongue 500 is unlocked to the lock nose 200, the protrusion 505 and the touch piece 702 are in a separation state. Thus, when the lock nose 200 contacts the lock tongue 500 in a downward direction, the lock nose 200 presses the locking part 501, so that the lock tongue 500 is driven by the locking part 501 to rotate integrally, the lock tongue 500 is locked on the lock nose 200, meanwhile, when the lock tongue 500 rotates, the protruding part 505 of the lock tongue 500 contacts with the touch piece 702, the protruding part 505 presses the touch piece 702 in the rotation process, so that the touch piece 702 and the controller 701 are in a contact state, the controller 701 receives a door closing signal, the microswitch 700 is in a closing state, and a door lock locking signal is transmitted to a user; similarly, when the door lock is opened, the hook 301 of the latch 300 rotates to the second position, the latch 300 and the latch 500 are buckled and opened, the latch 500 rotates under the action of the torsion provided by the second torsion spring 504, the protrusion 505 of the latch 500 is separated from the contact piece 702 while the latch 500 is separated from the lock nose 200, and the controller 701 receives a door opening signal, so that the micro switch 700 is in an open state, and transmits a signal for locking the door to a user.
