The specific operation description is as follows: the counter-clockwise rotation direction of the rotary toggle mechanism 400 is the second direction, and the clockwise rotation direction of the rotary toggle mechanism 400 is the first direction when facing the rotary toggle mechanism 400 in fig. 1. When the lock is locked in a normal state and unlocked, the rotary toggle mechanism 400 rotates in a second direction, and the rotary toggle mechanism 400 drives the locking part 300 to rotate in the rotating process so that the clamping hook 301 moves in a direction away from the clamping groove 201 until the clamping hook 301 is separated from the clamping groove 201; after the clamping groove 201 is released, the lock tongue component 200 is rotated to enable the clamping groove 201 to be far away from the clamping hook 301, the unlocking action is completed, and the lock is in a completely opened state as shown in fig. 2; in the above operation, when the locking groove 201 is released, the locking tongue part 200 can be rotated by a motor or a manual operation to separate the locking groove 201 from the locking hook 301, which is not limited by the present invention.

When the lock is closed, referring to fig. 2, an external force is applied to the latch bolt 200, for example, the latch bolt 200 is manually closed, and the latch bolt 200 is rotated to bring the latch slot 201 close to the latch hook 301; rotating the locking part 300 causes the hooks 301 to clamp the clamping grooves 201 so as to keep the lock tongue part 200 and the locking part 300 in a locking state in a matching way; the rotary toggle mechanism 400 is rotated in the first direction so as to further prop against the locking component 300 to limit the movement of the clamping hook 301 in a direction away from the clamping groove 201, the locking action is completed, the rotary toggle mechanism 400 stops rotating, and the lockset is in the locking state in fig. 1.

In this embodiment, the rotary shifting mechanism 400 is used to replace the conventional hook structure to realize the opening and closing of the lock, when the rotary shifting mechanism 400 rotates in the second direction, the hook 301 and the clamping groove 201 can be separated to realize unlocking, and when the lock is closed, the rotary shifting mechanism 400 rotates in the first direction to prop against the locking component 300, the degree of freedom of the locking component 300 is limited to limit the hook 301 to move away from the clamping groove 201, so that the hook 301 and the clamping groove 201 can be firmly matched in the locking state, and even if the hook is impacted by a side surface or the locking component 300 is shifted by an elongated hard object, the limitation of the rotary shifting mechanism 400 on the locking component 300 can not be released, thereby the lock can be prevented from being opened by side surface impact or malicious things by a person in the locking state, the anti-impact and anti-theft function is provided, and the protection capability of the lock is effectively improved.

When unlocking, the rotary shifting mechanism 400 drives the locking part 300 to rotate so as to enable the clamping hook 301 to move in a direction away from the clamping groove 201 until the clamping hook 301 is separated from the clamping groove 201, and after the locking is subsequently closed, the rotary shifting mechanism 400 is rotated so as to enable the lock tongue part 200 and the locking part 300 to be matched and kept in a locking state. To this end, referring to fig. 1, in some embodiments, the locking member 300 includes a locking plate 310 and a first return body 320, the locking plate 310 being rotatably provided on the surface of the lock base 100, the catch 301 being provided on the locking plate 310, the first return body 320 connecting the locking plate 310 with the lock base 100 to provide a return force for moving the catch 301 in a direction approaching the catch groove 201. By adopting the arrangement, the rotary toggle mechanism 400 drives the locking plate 310 to rotate during unlocking so as to separate the clamping hook 301 from the clamping groove 201, the clamping hook 301 rebounds to the position shown in fig. 2 in the direction close to the clamping groove 201 under the action of the first rebound body 320 after unlocking, when locking is required, the locking can be realized by directly pressing the lock tongue component 200 so that the clamping groove 201 of the lock tongue component 200 is clamped into the clamping hook 301, and the clamping hook 301 is moved to the direction close to the clamping groove 201 and clamped and fixed by not needing to manually or independently operate the locking plate 310, so that the operation is more convenient. Specifically, when the lock is manually closed, the latch bolt assembly 200 is pressed or pushed in a direction approaching the locking plate 310 until the catch 201 snaps into the catch 301.

In this embodiment, the first elastic body 320 includes a first torsion spring 321, the first torsion spring 321 and the locking plate 310 are disposed on a first mounting shaft 330 on the surface of the lock base 100 together, and one end of the first torsion spring 321 is fixed to the lock base 100, and the other end abuts against the locking plate 310. The rotary shifting mechanism 400 can be driven by the driving component 500, when the rotary shifting mechanism 400 drives the locking plate 310 to rotate to separate the clamping hook 301 from the clamping groove 201, the first torsion spring 321 coaxially arranged with the locking plate 310 deforms to store energy, and when the rotary shifting mechanism 400 passes over a driving interval and no longer drives the locking plate 310, the energy in the first torsion spring 321 is released and the clamping hook 301 is enabled to rebound towards the direction approaching the clamping groove 201.

It will be appreciated that in other embodiments, the first resilient body 320 may be a spring, and the locking plate 310 is directly connected to the lock base 100 by the spring, and the spring deforms and stores energy when the locking plate 310 rotates, and directly drives the hook 301 to rebound in a direction approaching the slot 201 after unlocking.

It will be appreciated that in other embodiments, the locking member 300 may comprise only the locking plate 310 without having a rebound function that does not affect the proper functioning of the basic function of the present invention.

When the locking member 300 is rotated to separate the hook 301 from the slot 201 during unlocking, the latch member 200 is also required to be rotated to move the slot 201 away from the hook 301, thereby completely unlocking the lock. To this end, referring to fig. 1, in some embodiments, the latch bolt assembly 200 includes a latch plate 210 and a second return body 220, the latch plate 210 being rotatably disposed on the surface of the latch base 100, a catch 201 being disposed on the latch plate 210, the second return body 220 connecting the latch plate 210 to the latch base 100 to provide a driving force to move the catch 201 in a direction away from the catch 301. In the unlocking process, after the locking plate 310 rotates to separate the hook 301 from the hook 201, the hook 201 is released, and the second elastic body 220 can provide a driving force to move the hook 201 away from the hook 301, so that manual operation or separate driving of the tongue plate 210 is not required to move the hook 201 away from the hook 301.

In this embodiment, the second elastic body 220 includes a second torsion spring 221, the second torsion spring 221 and the latch plate 210 are disposed on a second mounting shaft 230 on the surface of the latch base plate 100 together, one end of the second torsion spring 221 is fixed to the latch base plate 100, and the other end abuts against the latch plate 210. When the clamping groove 201 is locked with the clamping hook 301, the second torsion spring 221 coaxially arranged with the lock tongue plate 210 deforms to store energy, and after the clamping groove 201 is released, the energy in the second torsion spring 221 releases and drives the lock tongue plate 210 to rotate, so that the clamping groove 201 moves in a direction away from the clamping hook 301. In other embodiments, the second elastomer 220 may be a spring that directly connects the strike plate 210 to the strike plate 100, the spring being deformed to store energy to provide a driving force to move the catch 201 away from the catch 301 when the strike plate 210 is rotated, and the spring directly driving the strike plate 210 to move the catch 201 away from the catch 301 when the lock is unlocked.

It will be appreciated that in other embodiments, the tongue component 200 may include only the tongue plate 210 without having a rebound function that does not affect the proper functioning of the basic function of the present invention.

Referring to fig. 1 and 3, in some embodiments, the lock base 100 further includes a first limiting portion 340 and a second limiting portion 240, where the first limiting portion 340 is used to limit the excessive movement of the hook 301 in a direction approaching the hook 201, and the second limiting portion 240 is used to limit the excessive movement of the hook 201 in a direction away from the hook 301. Specifically, the first limiting portion 340 may be a limiting shaft disposed on the lock base 100, and the second limiting portion 240 may be a stop block disposed on the lock base 100.

Referring to fig. 1 and 2, in some embodiments, rotary dial mechanism 400 includes rotary dial column 410, rotary dial column 410 being rotatable about fixed axis 430 perpendicular to lock base 100.

Further, the rotary toggle mechanism 400 further includes a cam 420, where the cam 420 is coaxially disposed with the rotary toggle 410 and is driven by the driving member 500 to rotate; the anti-impact lock further comprises a first travel switch 700, a second travel switch 800 and a controller, wherein the second travel switch 800 is in contact with the bolt part 200 to detect the locking state of the bolt part 200, the first travel switch 700 is in contact with the cam 420 to detect the travel state of the rotary toggle mechanism 400 during unlocking, and the first travel switch 700, the second travel switch 800 and the driving part 500 are all electrically connected with the controller.

Specifically, the lock is normally locked, and at this time, the first travel switch 700 is in the off state, and the tongue 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 (a code scanning signal or other input signals) from the outside, for example, when a user scans a two-dimensional code to request the controller to unlock, the controller controls the driving part 500 to drive the rotary dial column 410 and the cam 420 to rotate in a second direction, and the rotary dial column 410 pushes the locking part 300 to rotate in the rotating process so as to enable the clamping hook 301 to move in a direction away from the clamping groove 201 until the clamping hook 301 is separated from the clamping groove 201; specifically, after the clamping groove 201 is released, the second elastic body 220 can drive the latch bolt component 200 to make the clamping groove 201 far away from the hook 301, and the latch plate 210 stops at the unlocking position under the torsion of the second elastic body 220 and the limiting action of the second limiting part 240 until the cam 420 in the rotary toggle mechanism 400 presses the first travel switch 700, and the rotary toggle mechanism 400 stops rotating, so that the unlocking action is completed. In this process, the cam 420 presses the first travel switch 700 to turn on the first travel switch 700, and then the cam 420 continues to rotate, and when the cam 420 presses the first travel switch 700 again, i.e., the first travel switch 700 is turned on for the second time, the controller controls the driving part 500 to stop rotating. During this time, the deadbolt assembly 200 rotates and moves away from the second travel switch 800, and the second travel switch 800 is open, at which point the controller receives an unlock signal. The controller determines the timing of cam stalling by employing the number of times the first travel switch 700 is closed with high accuracy.

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

Since the rotation of the driving part 500 such as a motor is easily affected by a voltage, if a time interval is used to control the stop rotation time of the jog dial 400, there may be a certain error. Therefore, the driving component 500 of this embodiment determines the locking state of the latch bolt component 200 and the travel state of the rotary striking mechanism 400 by receiving the detection signals of the first travel switch 700 and the second travel switch 800, and then controls the forward rotation and the reverse rotation of the rotary striking mechanism 400 and the position state of the rotary striking mechanism 400, so that the automatic control of the switching and locking process can be realized, and the control process is accurate and reliable.

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