[0098] Optionally, a first cam arm 414 and two second cam arms 415 are provided on the cam piece 413, the first cam arm 414 is located between the two second cam arms 415, the first cam arm 414 is located in the main lock slide groove 240, and a cam column 416 is provided on the first cam arm 414 in the direction of the sliding slide assembly 300, and a sliding U-shaped groove is provided at a position corresponding to the main lock slide groove 240 on the sliding plate 330, and the cam column 416 is located in the sliding U-shaped groove, so that the sliding slide assembly 300 can drive the cam piece 413 to rotate alone, and then drive the main lock tongue assembly 200 to telescopic movement, thereby increasing the number of connection points between the main lock tongue assembly 200 and the sliding slide assembly 300, so that the main lock tongue assembly 200 can be unlocked more precisely.

[0099] Optionally, a stopper 417 is provided on the side of the cam baffle 412 facing the cam piece 413. The stopper 417 can be used to block the second cam arm 415, and the stopper 417 and the first cam arm 414 are located in the same diameter direction, that is, the second cam arm 415 is located between the stopper 417 and the first cam arm 414. The cam piece 413 is movably connected to the mechanical shaft body 411. When the sliding plate assembly 300 drives the cam piece 413 to move, the wheel piece slides freely on the outer diameter of the mechanical shaft body 411 within the space between the second cam arm 415 and the stopper 417, so that the movement of the sliding plate assembly 300 will not drive the mechanical shaft body 411 to rotate, and thus will not cause the first plate member 600 to move upward when using electric unlocking.

[0100] Optionally, a second cam column 416 is provided on the second cam arm 415 on the side away from the through hole portion 140, and a torsion spring is connected to the second cam column 416, and the other end of the torsion spring is fixedly connected to the bracket assembly 170. The torsion spring is used to assist the cam piece 413 in resetting when the cam piece 413 rotates.

[0101] Optionally, a first slide plate inclined surface 630 and a first arc inclined surface 640 are provided on the side where the first slide plate member 600 abuts against the cam baffle 412. Two cam arms 418 and a cam arc surface 419 are provided on the outer circumference of the cam baffle 412. A cam arm arc surface 430 is provided on the cam arm 418. The cam arc surface 419 is located between the two cam arms 418. When the main lock tongue assembly 200 is in the telescopic state, the first arc inclined surface 640 cooperates with the cam arc surface 419, and the two cam arms 418 are in contact with the first slide plate inclined surface 630. When the lock is initially unlocked, the mechanical shaft itself The body 411 rotates counterclockwise, and the cam arm 418 on the side close to the main lock tongue assembly 200 pushes against the first slide plate inclined surface 630, causing the first slide plate member 600 to move upward. When the cam arm arc surface 430 slides into the first arc inclined surface 640, the first slide plate member 600 is in a state of temporarily not moving upward, and the main lock tongue assembly 200 continues to retract until the cam arm arc surface 430 moves to the end of the first arc inclined surface 640, and the main lock tongue assembly 200 is completely retracted into the through hole portion 140.

[0102] In some embodiments, as Figure 14 As shown, the first drag plate member 600 may include a groove portion 610 and a boss portion 620, the boss portion 620 may be located on one side of the groove portion 610, the manual unlocking assembly 400 may include a transmission shaft assembly 420, a handle is provided in the center of the transmission shaft assembly 420, two first transmission arms 421 may be symmetrically provided on the transmission shaft assembly 420, the transmission shaft assembly 420 may be provided in the groove portion 610, the boss portion 620 may be located between the two first transmission arms 421, by rotating the handle, and then rotating the transmission shaft assembly 420, so that the first transmission arm 421 rotates, pushing the boss portion 620 to move, and then pushing the first drag plate member 600 to move.

[0103] Optionally, the unlocking and matching process of the first transmission arm 421, the groove portion 610 and the boss portion 620 is similar to that of the mechanical shaft assembly 410, both of which push the first drag plate 600 upward through the mutual cooperation between the arc surface and the inclined surface, which will not be repeated here.

[0104] Optionally, a slide plate waist-shaped hole 660 is provided on the first slide plate part 600, and a slide plate guide column is provided on the side of the main lock tongue assembly 200 facing the first slide plate part 600. The slide plate guide column is located on the side of the slide plate waist-shaped hole 660 close to the transmission shaft assembly 420. A spring is provided in the slide plate waist-shaped hole 660, one end of the spring is connected to the side of the slide plate waist-shaped hole 660 away from the transmission shaft assembly 420, and the other end of the spring is connected to the slide plate guide column. When the first slide plate part 600 moves upward, the spring is compressed. When the manual unlocking assembly 400 rotates clockwise, the spring returns to its original state, prompting the first slide plate part 600 to move downward, making the manual unlocking assembly 400 more labor-saving.

[0105] In some embodiments, as Figure 8 As shown, the transmission shaft assembly 420 may include a transmission shaft 422, a transmission paddle and a transmission gear 424. The transmission shaft 422 may be arranged to pass through the base plate assembly. The transmission paddle may be arranged at the end of the transmission shaft 422 and toward the base plate assembly. The transmission gear 424 may be rotatably set on the base plate assembly through a gear positioning column. The transmission gear 424 may include a first gear and a second gear. The first gear may be engaged with the transmission paddle, and the second gear may be engaged with the first rack 310. When the transmission shaft 422 is rotated, the transmission paddle at the bottom is driven to rotate, and through the action of the first gear, the transmission gear 424 is driven to rotate. The second gear on the transmission gear 424 drives the first rack 310 to rotate, thereby driving the sliding drag assembly 300 to move.

[0106] Optionally, the transmission shaft 422 includes a first transmission shaft 428 and a second transmission shaft 429 , and the first transmission shaft 428 and the second transmission shaft 429 are linked together through the extended hexagonal shaft and the hexagonal hole to clamp the clutch push plate in the middle.

[0107] Optionally, a transmission boss may be provided on one side of the end of the transmission shaft 422, a thumbwheel circular hole may be provided in the center of the transmission thumbwheel, a thumbwheel groove may be provided on one side of the thumbwheel circular hole, the transmission shaft assembly 420 may be provided in the thumbwheel circular hole, and the transmission boss may be located in the thumbwheel groove. When the sliding plate assembly 300 drives the transmission gear 424 to move, the transmission gear 424 drives the transmission thumbwheel to move, and the thumbwheel groove gives the transmission boss a certain return space, so that the movement of the sliding plate assembly 300 will not drive the transmission shaft 422 to rotate, and thus will not cause the first plate component 600 to move upward when using electric unlocking.

[0108] In the manual unlocking state: First, when unlocking, the cam baffle 412 or the transmission shaft assembly 420 installed on the mechanical shaft assembly 410 rotates a certain angle to push the first carriage member 600 to slide upward, causing the electric gear 510 to slide upward synchronously and disengage from the second rack 320 on the sliding carriage assembly 300;

[0109] When the rotation continues, the cam baffle 412 moves the cam piece 413 to move the main lock slide 220 to unlock or lock. The transmission shaft assembly 420 drives the transmission gear 424 to mesh with the transmission gear 424 and rotate. The transmission gear 424 meshes with the first rack 310 of the sliding slide assembly 300, and the sliding slide assembly 300 drives the main lock tongue assembly 200 to unlock or lock.

[0110] During the unlocking process: when the main lock tongue assembly 200 retracts to a certain stroke, the first drag plate sliding member 870 on the main lock tongue assembly 200 engages and drives the oblique lock tongue assembly 800 to retract and unlock synchronously. At this time: after the door is pushed open, the door magnetic lock assembly 900 disengages from the limit of the buckle plate installed on the upper surface of the door frame, and extends out of the surface of the bottom plate 110 under the elastic force of the compression spring. The door magnetic drag plate 940 on the door magnetic lock assembly 900 compresses the first drag plate sliding member 870 on the main lock assembly to disengage from the engagement with the first oblique tongue side plate 811 in the oblique tongue assembly. Under the reset elastic force of the first elastic member 830, the oblique tongue assembly extends out of the bottom plate 110 to the limit stop.

[0111] When the main bolt assembly 200 cannot be locked, the mechanical key drives the mechanical shaft to drive the cam baffle 412 to move the inclined bolt push plate 711 and then move the inclined bolt paddle 712 to push the inclined bolt to realize the inclined bolt unlocking function; the transmission shaft drives the inclined bolt paddle 712 to push the inclined bolt to realize the inclined bolt unlocking function;

[0112] When the main lock tongue assembly 200 is extended or retracted, the drag plate column pushes the upper auxiliary lock drag plate part 780 to slide upward and the lower auxiliary lock drag plate part 780 to slide downward. In the upper auxiliary lock tongue assembly 730, the auxiliary lock drag plate part 780 pushes the auxiliary lock rocker rod 732 to rotate upward, and the third rocker rod fixing column 736 and the fourth rocker rod fixing column 737 on the auxiliary lock rocker rod 732 push the corresponding auxiliary lock tongue assembly 730 to extend or retract; in the lower auxiliary lock tongue assembly 730, the auxiliary lock drag plate part 780 pushes the auxiliary lock rocker rod 732 to rotate downward, and the third rocker rod fixing column 736 and the fourth rocker rod fixing column 737 on the auxiliary lock rocker rod 732 push the corresponding auxiliary lock tongue assembly 730 to extend or retract.

[0113] In some embodiments, the electric unlocking assembly 500 may include a detection member, and a sensing member 210 may be provided at one end of the main lock tongue assembly 200 away from the through hole portion 140. The detection member may be located above the sensing member 210. The detection member is used to detect the position of the sensing member 210, and can control unlocking or locking according to the position of the sensing member 210.

[0114] Alternatively, as Figure 7 and Figure 10As shown, the electric unlocking assembly 500 includes a first PCBA board 171, which is a main control board. The detection component includes a first sensor 175 and a second sensor 176. The sensing component 210 includes an induction magnet, which is located on the main lock slide 220. The first sensor 175 and the second sensor 176 are electrically connected to the first PCBA board 171. During the unlocking and locking process of the main lock tongue assembly 200, the induction magnet moves between the first sensor 175 and the second sensor 176. According to the detection results of the first sensor 175 and the second sensor 176, the electric unlocking assembly 500 is controlled to drive the electric gear 510 to rotate, drive the second rack 320 to move, and then drive the sliding slide assembly 300 to slide along the bottom plate 110, driving the main lock tongue assembly 200 to extend or retract the through-hole portion 140, thereby realizing electric unlocking or locking.

[0115] Alternatively, as Figure 9 As shown, the electric unlocking assembly 500 includes a second PCBA board 172, a third sensor 173 and a fourth sensor 174. The third sensor 173 is located below the oblique lock tongue assembly 800 and is used to detect the position of the oblique lock tongue assembly 800. The fourth sensor 174 is located below the door magnetic lock assembly 900 and is used to detect the position of the door magnetic lock assembly 900. The first PCBA board 171 is electrically connected to the second PCBA board 172, and the second PCBA board 172 is electrically connected to the first PCBA board 171. When the signals detected by the first sensor 175, the second sensor 176, the third sensor 173 and the fourth sensor 174 meet the preset conditions, the first PCBA board 171 sends an electrical signal to drive the first motor 520 to rotate, thereby driving the electric gear 510 to rotate, the electric gear 510 drives the second rack 320 to move, the second rack 320 drives the sliding plate assembly 300 to move, and the sliding plate assembly 300 drives the main lock tongue assembly 200 to unlock or lock.

[0116] Optionally, the first PCBA board 171 and the second PCBA board 172 are both located in the bracket assembly 170 , giving the first PCBA board 171 and the second PCBA board 172 a certain bearing capacity.

[0117] When the first plate member 600 is reset downward, the spring returns to its original state, pushing the electric gear 510 toward the second rack 320 until the electric gear 510 engages with the second rack 320.

[0118] When the electric signal is used to open or close the lock: the electric gear 510 is meshed with the second rack 320 on the sliding drag plate assembly 300 for transmission; the sliding plate 330 first compresses the slide spring relative to the main lock tongue assembly 200 to a certain stroke, and the first cam arm 414 of the cam piece 413 is disengaged from the locking position of the main lock tongue assembly 200. Then the sliding plate 330 contacts the main lock tongue assembly 200, driving the main lock tongue assembly 200 to slide out or retract.
