[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0025] See also Figure 1-Figure 5 An induction lock structure includes a lock body shell 1, and the lock body shell style can refer to the existing design.

[0026] The lock body shell 1 is movably provided with a sensing tongue unit, an inclined tongue unit and a main locking tongue unit. Specifically, the sensing tongue unit includes a sensing tongue 21 and a first movable part 22 that moves synchronously therewith, the main locking tongue unit includes a main locking tongue 31 and a second movable part 32 that cooperates with the main locking tongue in transmission, and the inclined tongue unit includes an inclined tongue 41 and a third movable part 42 that moves synchronously therewith.

[0027] The sensing tongue 21 , the main locking tongue 31 and the oblique tongue 41 all have a first state of being retracted into the lock housing 1 and a second state of being extended out of the lock housing 1 . When the relevant components are extended out of the lock housing 1 , a locking effect can be achieved.

[0028] In this embodiment, a first fixing member 51 is fixedly provided on the lock body housing 1, the lower end of the first movable member 22 passes through the first fixing member 51, and a first spring 52 for resetting the sensing tongue 21 is sleeved on the first movable member 22, one end of the first spring 52 abuts against the sensing tongue 21 or the upper end of the first movable member 22 (the upper end may be extended laterally to form a flange portion for abutting the spring), and the other end abuts against the first fixing member 51, such as Figure 1 , Figure 2 , Figure 4 shown.

[0029] In this embodiment, a second fixing member 53 is fixed to the lock body housing 1, the lower end of the third movable member 42 passes through the second fixing member 53, and a second spring 54 for resetting the inclined tongue 41 is sleeved on the third movable member 42, one end of the second spring 54 abuts against the upper end of the inclined tongue 41 or the third movable member 42 (the upper end may be extended laterally to form a flange portion for abutting the spring), and the other end abuts against the second fixing member 53.

[0030] In this embodiment, the main lock tongue 31 is connected to the handle member 6 in a transmission manner, and the second movable member 32 is disposed on the handle member 6 and moves synchronously with the movement of the handle member 6. For the transmission connection method between the main lock tongue 31 and the handle member 6, reference may be made to the patent document CN220184852U proposed earlier by the applicant, wherein the main lock tongue referred to herein corresponds to the mop piece of the patent document, and the handle member referred to herein corresponds to the second handle member of the patent document.

[0031] like Figure 1 , Figure 2As shown, the second movable member 32 is arranged on the back of the handle member 6 , and it swings synchronously with the handle member 6 .

[0032] In this embodiment, a PCB board 7 is also fixedly provided on the lock body housing 1, and a first induction switch 81, a second induction switch 82 and a third induction switch 83 are electrically connected to the PCB board 7, wherein the first induction switch 81 is used to cooperate with the first movable member 22 to give a position status signal of the induction tongue 21; the second induction switch 82 is used to cooperate with the second movable member 32 to give a position status signal of the main lock tongue 31; the third induction switch 83 is used to cooperate with the third movable member 42 to give a position status signal of the oblique tongue 41.

[0033] As one implementation manner, the first induction switch 81 and the second induction switch 82 are normally open switches, and the third induction switch 83 is a normally closed switch.

[0034] As one implementation mode of the above-mentioned sensor switch position layout, in this embodiment, the PCB board 7 includes a first portion 71 arranged longitudinally and a second portion 72 arranged transversely, the first sensor switch 81 is arranged at the upper end of the first portion 71, the second sensor switch 82 is arranged at the lower end of the first portion 71, and the third sensor switch 83 is arranged at the outer end of the second portion 72. Figure 3 shown.

[0035] To facilitate the installation of related induction switches, in this embodiment, a first extension position 711 extends from the lower end of the first portion 71, and the second induction switch 82 is installed at the first extension position 711; a second extension position 721 extends from the outer end of the second portion 72, and the third induction switch 83 is installed at the second extension position 721.

[0036] Furthermore, the first portion 71 and the second portion 72 are integrally formed to form a whole PCB board.

[0037] In this embodiment, the PCB board 7 is connected to the lock handle signal. When closing or opening the door, the movement of the sensing tongue and the oblique tongue will trigger the first sensing switch and the third sensing switch, and the movement of the main lock tongue will trigger the second sensing switch.

[0038] For signal judgment:

[0039] 0 state: signal switch is closed; 1 state: signal switch is open;

[0040] Among them, the 0 state includes: main lock tongue out, oblique tongue back and induction tongue back; 1 state includes: main lock tongue back, oblique tongue out and induction tongue out.

[0041] Regarding compatibility, after the lock body is powered on, the lock body needs to be connected to the motor to drive the lock on / off once to detect whether there is a lock body. To unlock the lock without a motor, the main lock tongue and the oblique tongue need to be moved in until "Unlocked" is displayed, and the lock body is detected.

[0042] Unlocking: judged and stopped by the stall current, the main lock tongue returns + the oblique lock tongue moves forward, judging that there is an electronic lock body.

[0043] Unlocking: judged and stopped by the stall current, the main lock tongue comes out + the oblique lock tongue comes out, judging that there is an electronic lock body.

[0044] Motor rotation time: After unlocking, there is a 4-5s delay, which is the door opening time. After this time, the motor will flip.

[0045] Automatic lock:

[0046] Case 1: After the motor flips over after unlocking, the sensor tongue is detected to be in the 0 state for 10 seconds and then the lock is automatically closed.

[0047] Case 2: If the sensor tongue is detected to be in the 0 state and the inclined tongue changes from 0 to 1, the door will be automatically locked after 2 seconds.

[0048] Door handle unlocking: When an electronic lock body is detected and the main lock tongue returns a signal of 1 in the locked state, it is judged as a handle switch, without motor flipping, and the other effects are the same as electronic unlocking.

[0049] Door handle locked: If an electronic lock body is detected and the main lock tongue outputs a 0 signal in the unlocked state, it is determined that the handle is locked and there is no motor rotation. Other effects are the same as electronic locking.

[0050] Half-close alarm: After the door is opened, if the oblique tongue advance + sensor tongue advance is detected for 4 seconds, the half-close alarm will sound 3 times, and the front panel will display "Door not closed properly" and upload the information to the app (the half-close status is only detected once during the entire unlocking process).

[0051] 20s door not closed alarm: After the door is opened, if it is not closed within 20s, the alarm will be issued three times, the front panel will display "Door not closed properly" and upload the information to the app (20s door not closed alarm is only detected once in the entire process after unlocking).

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
