After verifying the unlocking signal, the controller 630 transmits the unlocking signal to the driving motor 410 to make the driving motor 410 rotate forward or reversely. The first transmission mechanism 420 is used to abut against the first abutting portion 331. The driving motor 410 can drive the first abutting portion 331 to rotate around the first rotating shaft 370 through the first transmission mechanism 420 to drive the bolt rudder 310 to swing, so that the extension portion 210 of the bolt assembly 200 can be extended and retracted; the first transmission mechanism 420 can transmit the power of the driving motor 410 to the first abutting portion 331, so that the first abutting portion 331 can rotate around the first rotating shaft 370, and the bolt rudder 310 also rotates, so that the toggle section 380 of the bolt rudder 310 swings, so as to drive the bolt assembly 200 to extend out of the first bolt hole 120 or retract from the first bolt hole 120. That is, the driving assembly 400 can drive the locking tongue assembly 200 to extend out of the first locking tongue hole 120, and can also drive the locking tongue assembly 200 to retract from the first locking tongue hole 120, so as to achieve the purpose of automatic locking and automatic unlocking.

[0090] In this embodiment, when the bolt steering wheel 310 swings in one direction, it is an unlocking movement; otherwise, it is a locking movement. For the convenience of explanation, when the bolt steering wheel 310 rotates forward, the bolt steering wheel 310 drives the toggle section 380 to approach the first bolt hole 120, that is, pushes the bolt assembly 200 out of the first bolt hole 120, which is the locking movement of the bolt steering wheel 310; when the bolt steering wheel 310 rotates reversely, the bolt steering wheel 310 drives the toggle section 380 away from the first bolt hole 120, that is, pushes the bolt assembly 200 to retract from the first bolt hole 120 into the housing 100, which is the unlocking movement of the bolt steering wheel 310.

The handle block 510 is used to connect to the door handle in the room. When the user needs to open the door in the room, the door handle can be turned, and the door handle drives the handle block 510 to rotate. The handle block 510 transmits power to the second abutting portion 332 through the second transmission mechanism 520, so that the second abutting portion 332 rotates around the first rotating shaft 370, and then the bolt steering rudder 310 can be driven to reverse through the second abutting portion 332, so that the bolt assembly 200 is retracted into the housing 100, so as to achieve the purpose of unlocking. That is, the handle unlocking assembly 500 and the driving assembly 400 drive the lock tongue steering 310 through the second transmission mechanism 520 and the first transmission mechanism 420 respectively, and both can achieve the function of unlocking the lock body. The handle unlocking assembly 500 and the driving assembly 400 share a lock tongue steering 310, which can save space, make the structure simpler, and save costs.

[0092] The driving assembly 400 of the lock body of this embodiment drives the bolt rudder 310 of the rudder assembly 300 to rotate by using the driving motor 410 and the first transmission mechanism 420. The driving motor 410 of the driving assembly 400 can rotate forward and reverse, and can drive the bolt rudder 310 to swing in two directions, so that the bolt assembly 200 extends out of the housing 100 or retracts into the housing 100 under the drive of the driving motor 410, so as to achieve the purpose of automatic locking and automatic unlocking of the lock body; secondly, the handle unlocking assembly 500 drives the bolt rudder 310 of the rudder assembly 300 to rotate in the unlocking direction through the handle dial block 510 and the second transmission mechanism 520, so that the user can directly grasp the handle to open the door indoors, and the unlocking action is simpler and convenient to open the door; and the driving assembly 400 and the handle unlocking assembly 500 share a bolt rudder 310 to drive the bolt assembly 200, so that the lock body is simpler, the internal space of the lock body is saved, the number of parts is reduced, and the cost is saved. Therefore, when the lock body is unlocked outdoors, only one-hand verification or face recognition unlocking information is required, and the drive component 400 can open the lock body, making it convenient for the user to open the door; when unlocking indoors, the user can open the door by turning the indoor door handle with one hand, making the indoor and outdoor unlocking actions simpler, making it convenient for users who cannot free their hands to open the door, thereby improving the user experience.

[0093] In some embodiments of the present invention, reference Figures 4 to 8 The bolt rudder 310 is provided with a rotating seat 320, and the rotating seat 320 is rotatably connected with the first rotating shaft 370; the first abutting portion 331 and the second abutting portion 332 are arranged on the rotating seat 320. The toggle section 380 of the bolt rudder 310 is a toggle arm arranged on the rotating seat 320, the rotating seat 320 is cylindrical, and the first abutting portion 331 and the second abutting portion 332 are both arranged on the rotating seat 320, which can facilitate the first transmission mechanism 420 and the second transmission mechanism 520 to drive the rotating seat 320 to rotate around the first rotating shaft 370, so as to drive the bolt rudder 310 to rotate around the first rotating shaft 370.

[0094] On the basis of the above, refer to Figures 4 to 8 The rotating seat 320 is provided with a toggle block 330, and the first abutting portion 331 and the second abutting portion 332 are both provided on the toggle block 330. That is, the first transmission mechanism 420 and the second transmission mechanism 520 both drive the rotating seat 320 to rotate through the toggle block 330, so as to drive the bolt toggle rudder 310 to rotate. The structure is integrated into a toggle block 330, which can conveniently control the force points of the first transmission mechanism 420 and the second transmission mechanism 520, so as to drive the bolt toggle rudder 310 to rotate. Among them, the toggle block 330 and the toggle section 380 are located in the same radial direction of the first rotating shaft 370, so as to facilitate the first transmission mechanism 420 and the second transmission mechanism 520 to drive the toggle section 380 to swing.

[0095] In some embodiments of the present invention, referenceFigures 4 to 11 The second transmission mechanism 520 has a second toggling member 530; the second toggling member 530 is provided with a fourth abutting portion 531 for abutting against the second abutting portion 332; the handle toggle block 510 drives the second toggling member 530 to rotate around the first rotating shaft 370 through the second transmission mechanism 520, so that the fourth abutting portion 531 abuts against the second abutting portion 332. That is, the second toggling member 530 is a transmission member for the second transmission mechanism 520 to act on the bolt steering wheel 310, and the second toggling member 530 rotates around the first rotating shaft 370; when the handle toggle block 510 rotates, the second toggling member 530 is driven to rotate through the second transmission mechanism 520, then the fourth abutting portion 531 rotates around the first rotating shaft 370, so that the fourth abutting portion 531 abuts against the second abutting portion 332. Therefore, the fourth abutting portion 531 can drive the second abutting portion 332 to rotate around the first rotating shaft 370 to drive the bolt steering wheel 310 to reverse, so that the bolt steering wheel 310 pushes the bolt assembly 200 to retract from the first bolt hole 120 into the housing 100, and the bolt assembly 200 is unlocked. By setting to rotate around the same first rotating shaft 370, when the fourth abutting portion 531 abuts against the second abutting portion 332, the second toggling member 530 can better drive the second abutting portion 332 to rotate around the first rotating shaft 370, so that the second transmission mechanism 520 can better transmit power to the bolt steering wheel 310, facilitating unlocking.

[0096] In some embodiments of the present invention, referring to Figures 4 to 11 , a second arc-shaped chute 532 is provided on the inner side of the second toggling member 530, the second abutting portion 332 extends into the second arc-shaped chute 532, and the fourth abutting portion 531 is located in the second arc-shaped chute 532. The second toggling member 530 can be sleeved on the toggling block 330, so that the second abutting portion 332 is inserted into the second arc-shaped chute 532. The center of the second arc-shaped chute 532 is located on the first rotating shaft 370. The size of the second arc-shaped chute 532 is larger than the size of the second abutting portion 332, so that the second abutting portion 332 can extend into the second arc-shaped chute 532. The second abutting portion 332 can slide along the second arc-shaped chute 532 to prevent the fourth abutting portion 531 and the second abutting portion 332 from jamming. The fourth abutting portion 531 is a convex block extending into the second arc-shaped chute 532. It should be noted that since the handle unlocking assembly 500 only performs the unlocking movement of the bolt assembly 200, when the driving assembly 400 drives the bolt steering wheel 310 to lock, the second abutting portion 332 also rotates forward. Therefore, a second blank section 533 is provided in the second arc-shaped chute 532; the second blank section 533 is provided on one side in the forward rotation direction of the second abutting portion 332, and the length of the second blank section 533 is greater than or equal to the stroke of the second abutting portion 332 from the locked state to the unlocked state. Then, when the driving assembly 400 drives the bolt steering wheel 310 to lock, the second abutting portion 332 rotates forward along the second blank section 533, which can reduce the interference of parts and ensure the successful locking of the driving assembly 400 driving the bolt assembly 200.

[0097] In some embodiments of the present invention, reference Figures 4 to 11 The second transmission mechanism 520 also has a first transmission member 540, a second transmission member 550, and a first reset device 560. The first transmission member 540 is rotatably connected to the shell 100; the handle block 510 is provided with a push block 511, and the first reset device 560 is used to drive the first transmission member 540 to abut against the push block 511; the middle part of the second transmission member 550 is rotatably connected to the shell 100, one end of the second transmission member 550 cooperates with the second toggle member 530 for transmission, and the other end of the second transmission member 550 cooperates with the first transmission member 540 for transmission; when the handle block 510 rotates, the push block 511 drives the first transmission member 540 to rotate, and the first transmission member 540 drives the second toggle member 530 to rotate around the first rotating shaft 370 through the second transmission member 550. One end of the first transmission member 540 is used to abut against the second transmission member 550, and the other end of the first transmission member 540 is used to abut against the pushing block 511, and the middle part of the first transmission member 540 is rotatably connected to the shell 100; therefore, when the handle block 510 rotates, the pushing block 511 drives one end of the first transmission member 540 to rotate, and the other end of the first transmission member 540 drives the end of the second transmission member 550 to rotate, and then the second transmission member 550 transmits power to the second toggle member 530, so that the second toggle member 530 rotates around the first rotating shaft 370, so as to drive the lock tongue rudder 310 to perform an unlocking movement, thereby achieving the purpose of unlocking the lock tongue assembly 200.

[0098] On the basis of the above, refer to Figures 4 to 11The push-pull block 511 is provided with a toggle groove 512, the first transmission member 540 is provided with a first abutting block 541, and the first abutting block 541 is provided at the end of the first transmission member 540. The first reset device 560 is used to drive the first abutting block 541 of the first transmission member 540 to extend into the toggle groove 512, and the toggle groove 512 is provided with a first toggle surface 513 and a second toggle surface 514 on both sides of the first abutting block 541; when the first abutting block 541 abuts against the first toggle surface 513, and the handle toggle block 510 rotates forward, the first toggle surface 513 passes through the first abutting block 541. The first transmission member 540 is driven to rotate, that is, the first transmission member 540 rotates in the unlocking direction, so as to drive the second transmission member 550, the second toggle member 530, and the bolt steering rudder 310 to rotate, so that the bolt assembly 200 is unlocked; when the first abutting block 541 abuts against the second toggle surface 514, and the handle toggle block 510 is reversed, the second toggle surface 514 drives the first transmission member 540 to rotate through the first abutting block 541, that is, the first transmission member 540 rotates in the unlocking direction, so as to drive the second transmission member 550, the second toggle member 530, and the bolt steering rudder 310 to rotate, so that the bolt assembly 200 is unlocked. Therefore, when it is necessary to unlock the door indoors, the user can swing the door handle in two directions, and the handle unlocking assembly 500 can be used to drive the bolt assembly 200 to unlock. In this embodiment, the ends of the first toggle surface 513 and the second toggle surface 514 are connected to form a V-shaped abutting surface; in the initial state, the first reset device 560 drives the first abutting block 541 to abut the position between the first toggle surface 513 and the second toggle surface 514, so when the handle block 510 rotates forward, the first abutting block 541 abuts against the first toggle surface 513; when the handle block 510 rotates reversely, the first abutting block 541 abuts against the second toggle surface 514. The angle between the first toggle surface 513 and the second toggle surface 514 is 110 degrees to 150 degrees.

[0099] In order to reduce the friction between the first contact block 541 and the first shifting surface 513 or the second shifting surface 514, refer to Figures 4 to 11 The first contact block 541 is provided with a first cylindrical surface 542 on the outside thereof, and the first cylindrical surface 542 is used to contact the first toggle surface 513 and the second toggle surface 514; the first transmission member 540 is provided with a second rotating shaft 543 rotatably connected to the first contact block 541. That is, the first contact block 541 is cylindrical, and the central axis of the first contact block 541 is the second rotating shaft 543. When the first contact block 541 moves along the first toggle surface 513 or the second toggle surface 514, the first contact block 541 can rotate by itself, and the friction between the first contact block 541 and the first toggle surface 513 or the second toggle surface 514 is a rolling friction force, which facilitates the first contact block 541 to move along the first toggle surface 513 or the second toggle surface 514.

[0100] In some embodiments of the present invention, reference Figures 4 to 11, a plurality of first matching teeth 534 are arranged on the outer side of the second toggle member 530, and the plurality of first matching teeth 534 are sequentially distributed around the first rotating shaft 370; a plurality of second matching teeth 551 for meshing with the first matching teeth 534 are arranged at one end of the second transmission member 550. That is, the second toggle member 530 and the second transmission member 550 are meshed and transmitted through the matching teeth, ensuring that the second transmission member 550 transmits power to the second toggle member 530, thereby preventing the second transmission mechanism 520 from failing. In addition, the second transmission member 550 and the second toggle member 530 can be connected and transmitted through a crank rocker mechanism and a crank slider mechanism.

[0101] In some embodiments of the present invention, reference Figures 2 to 8 , Figure 12 The first transmission member 540 is provided with a first transmission arm 544, and the end of the second transmission member 550 is provided with a second transmission arm 552; when the first transmission member 540 rotates under the drive of the handle block 510, the first transmission arm 544 pushes the second transmission arm 552 to rotate the second transmission member 550. The first transmission arm 544 is provided at one end of the first transmission member 540 close to the second transmission member 550, and the first transmission arm 544 is used to transmit power to the second transmission arm 552. When the handle block 510 rotates, the first transmission member 540 rotates around its middle part, and the first transmission arm 544 will push the second transmission arm 552, so that the second transmission member 550 swings away from the end of the second transmission arm 552 to transmit power to the second toggle member 530.

[0102] In some embodiments of the present invention, reference Figures 2 to 8 , Figure 12 The first transmission mechanism 420 has a first toggle member 430, a first arc-shaped slot 431 is arranged on the inner side of the first toggle member 430, the first abutment portion 331 is inserted into the first arc-shaped slot 431, the first toggle member 430 is provided with a third abutment portion 432, and the third abutment portion 432 is located in the first arc-shaped slot 431. The driving motor 410 drives the first toggle member 430 to rotate around the first rotating shaft 370 through the first transmission mechanism 420, so that the third abutment portion 432 abuts against the first abutment portion 331. The first toggle member 430 can be sleeved on the outer side of the toggle block 330, so that the first abutment portion 331 extends into the first arc-shaped slot 431 of the first toggle member 430, and the center of the first arc-shaped slot 431 is located on the first rotating shaft 370. The first abutment portion 331 can move along the first arc-shaped slot 431 to facilitate the two sides of the third abutment portion 432 to abut against the first abutment portion 331, so as to drive the lock tongue toggle 310 to rotate forward or reverse, so that the lock tongue assembly 200 is locked or unlocked.

[0103] Among them, on the basis of the above, refer to Figures 2 to 8 , Figure 12The first transmission mechanism 420 includes a driving gear 440 and a transmission gear 450; the transmission gear 450 has a plurality of first meshing teeth 451 and a plurality of second meshing teeth 452; the first meshing teeth 451 mesh with the driving gear 440, and the first toggle member 430 is provided with a third meshing tooth 433 meshing with the second meshing tooth 452; the driving motor 410 is provided with a rotating rod, and the driving gear 440 is arranged on the rotating rod. The first toggle member 430 is a gear, and a first arc-shaped slide groove 431 is provided on the inner side of the first toggle member 430, and a third meshing tooth 433 is provided on the outer side; the driving motor 410 drives the driving gear 440 to rotate forward or reverse through the rotating rod, and then transmits power to the first toggle member 430 through the transmission gear 450, so that the first toggle member 430 can also rotate forward or reverse, so as to drive the bolt toggle 310 to rotate forward or reverse.

[0104] In order to detect the rotational travel of the first toggle member 430, refer to Figures 2 to 8 , Figure 12 The lock body of this embodiment also includes a detection gear 600 and a first detection switch 620; the detection gear 600 is rotatably connected to the shell 100, the first detection switch 620 is arranged on the shell 100, the detection gear 600 is meshed with the third meshing tooth 433, the detection gear 600 is provided with a first detection boss 610, the first detection switch 620 is used to detect the first detection boss 610, and the first detection switch 620, the driving motor 410 and the controller 630 are signal-connected. The controller 630 controls the driving time of the driving motor 410, and the first detection switch 620 is used to feedback the number of rotations of the detection gear 600. When the first toggle member 430 rotates, the third meshing tooth 433 drives the detection gear 600 to rotate, that is, drives the first detection boss 610 to rotate around the center of the detection gear 600. Therefore, the first detection switch 620 can feedback the number of rotations of the detection gear 600 to the controller 630 according to the number of times the first detection boss 610 is detected; since the first toggle member 430 and the detection gear 600 are meshed through the meshing teeth, the transmission ratio thereof has been determined, and the controller 630 can judge the stroke of the first toggle member 430 driven by the driving motor 410 according to the number of circles fed back by the first detection switch 620, and timely control the driving motor 410 to turn off, so as to prevent the driving motor 410 from continuously rotating in the same direction, causing the lock tongue toggle rudder 310 and the toggle slot 220 to be stuck.

[0105] On the basis of the above, refer to Figures 2 to 8 , Figure 12The first arc-shaped slide groove 431 is provided with a first blank section 434 on both sides of the first abutting portion 331, wherein the first blank section 434 located on the side of the first abutting portion 331 in the forward rotation direction has a length greater than or equal to the stroke of the first abutting portion 331 from the locked state to the unlocked state, so that when the handle unlocking assembly 500 drives the lock tongue rudder 310 to unlock, the first abutting portion 331 can move along the first blank section 434 to avoid the first abutting portion 331 from abutting against the third abutting portion 432, thereby avoiding motion interference. Moreover, in order to prevent the driving motor 410 from getting stuck, in the initial state, the first abutting portion 331 is located in the middle of the first arc-shaped slide groove 431, and the lengths of the first empty sections 434 on both sides of the first abutting portion 331 are equal; when the driving motor 410 drives the first toggle member 430 to rotate forward through the first transmission mechanism 420 and the third abutting portion 432 pushes the first abutting portion 331 and the lock tongue steering rudder 310 to rotate forward, so that the lock tongue assembly 200 extends to the locked state, at this time, the first detection switch 620 monitors that the detection gear 600 rotates one circle, and the controller 630 controls the driving motor 410 to stop for one second; then the driving motor 410 reverses, causing the first toggle member 430 to reverse to the position of the initial state. At this time, the first detection switch 620 monitors that the detection gear 600 rotates one circle, then the reset is completed, and the controller 630 controls the drive motor 410 to stop; similarly, when the drive motor 410 drives the first toggle member 430 to reverse through the first transmission mechanism 420, and the lock tongue assembly 200 retracts to the unlocked state, the first detection switch 620 monitors that the detection gear 600 rotates one circle, and the controller 630 controls the drive motor 410 to stop for one second; then the drive motor 410 rotates forward, causing the first toggle member 430 to reverse to the initial state position. At this time, the first detection switch 620 monitors that the detection gear 600 rotates one circle, then the reset is completed, and the controller 630 controls the drive motor 410 to stop.

[0106] In the preferred embodiment of the present invention, in order to make the structure more compact, refer to Figures 2 to 8 , the first toggle member 430 is rotatably connected to the rotating seat 320, the second toggle member 530, the first toggle member 430, and the rotating seat 320 are sequentially arranged along the length direction of the first rotating shaft 370, and the toggle block 330 sequentially passes through the first arc-shaped slide groove 431 and the second arc-shaped slide groove 532. That is, the second toggle member 530 and the first toggle member 430 are sequentially stacked on the rotating seat 320, and the toggle block 330 on the rotating seat 320 can directly extend into the first arc-shaped slide groove 431 and the second arc-shaped slide groove 532, so as to save space in the lock, make the structure more compact, and facilitate assembly.

[0107] On the basis of the above, refer to Figures 2 to 8In order to facilitate the installation of the first toggle member 430 and the second toggle member 530 and to separate the first toggle member 430 and the second toggle member 530, a first step 333 slidably connected to the first arc-shaped slide groove 431 is provided on the outer side of the toggle block 330, and a second step 334 slidably connected to the second arc-shaped slide groove 532 is provided on the outer side of the toggle block 330. The distance between the first step 333 and the first rotating shaft 370 is greater than the distance between the second step 334, so the second toggle member 530 abuts against the smaller first step 333, and there is a matching gap between the first toggle member 430 and the second toggle member 530, so that the second toggle member 530 and the first toggle member 430 do not interfere with each other, ensuring that the movement of the handle unlocking assembly 500 and the movement of the driving assembly 400 do not interfere with each other.

[0108] In a preferred embodiment of the present invention, referring to Figure 1 , Figure 2 , Figure 3 , Figure 13 , Figure 14 The lock body of this embodiment also includes: a lock cylinder unlocking assembly 700; the lock cylinder unlocking assembly 700 includes a lock cylinder 710 and a third transmission mechanism 720; the lock cylinder 710 has a lock cylinder paddle 711, and the lock cylinder paddle 711 is rotatably arranged on the lock cylinder 710; the third transmission mechanism 720 is provided with a fifth abutting portion 731, and the lock tongue steering rudder 310 is provided with a fork transmission portion 340 for abutting with the fifth abutting portion 731; when the lock tongue assembly 200 is in a locked state, the lock cylinder paddle 711 drives the fifth abutting portion 731 through the third transmission mechanism 720 to drive the fork transmission portion 340 to rotate around the first rotating shaft 370, so as to drive the lock tongue steering rudder 310 to swing in the unlocking direction, so that the lock tongue assembly 200 moves from the locked state to the unlocked state. The lock core 710 is a common lock on the market. After the key is inserted into the lock core 710, the key can be turned to drive the lock core paddle 711 to rotate, that is, by rotating the lock core paddle 711, the lock tongue assembly 200 can be driven to move from the locked state to the unlocked state through the third transmission mechanism 720.

The second reset device 750 is used to drive the fork shifting piece 732 of the transmission fork 730 to approach the lock cylinder shifting piece 711, so that the lock cylinder shifting piece 711 can drive the fork shifting piece 732 after rotating, so as to drive the transmission fork 730 away from the lock cylinder 710; when the transmission fork 730 is away from the lock cylinder 710, the moving direction of the transmission fork 730 is the same as the unlocking direction of the lock tongue shifting rudder 310, then the fifth abutting portion 731 of the transmission fork 730 abuts against the fork transmission portion 340, and pushes the lock tongue shifting rudder 310 to make an unlocking movement, and the lock tongue assembly 200 can move from the locked state to the unlocked state. It should be noted that the fifth abutting portion 731 is located on the side of the transmission fork 730 away from the lock cylinder shifting piece 711, so that the fifth abutting portion 731 can drive the lock tongue shifting rudder 310 when it is away from the lock cylinder 710.

That is, after the safety tongue assembly 930 retracts into the housing 100, one of the driving assembly 400, the handle unlocking assembly 500, and the lock head unlocking assembly 700 must be used to unlock the double-sided inclined tongue assembly 800 to make the double-sided inclined tongue assembly 800 in an active state before the door can be opened.

[0122] In some embodiments of the present invention, referring to Figures 2 to 18 , the lock body further includes: a third detection switch 650;

[0123] The lock tongue deflector 310 is provided with a second detection boss 350 and a third detection boss 360. The second detection boss 350 and the third detection boss 360 are arranged in sequence around the first rotating shaft 370. The third detection switch 650 is arranged on the housing 100. When the lock tongue assembly 200 is in the locked state, the second detection boss 350 corresponds to the third detection switch 650. When the lock tongue assembly 200 is in the unlocked state, the third detection boss 360 corresponds to the third detection switch 650. The third detection switch 650, the drive motor 410 and the controller 630 are signal-connected. The third detection switch 650 is used to detect whether the lock tongue assembly 200 is in the unlocked state or the locked state, so as to feed back the position information of the lock tongue assembly 200 to the controller 630, enabling the controller 630 to judge whether the drive motor 410 stops, rotates forward or rotates backward at this time. For example, when the drive motor 410 drives the lock tongue deflector 310 to rotate forward through the first transmission mechanism 420, the second detection boss 350 is detected at the third detection switch 650, which indicates that the lock tongue assembly 200 has reached the locked state at this time, and the controller 630 outputs a stop signal to the drive motor 410 to stop the drive motor 410. Similarly, when the drive motor 410 drives the lock tongue deflector 310 to rotate backward through the first transmission mechanism 420, the third detection boss 360 is detected at the third detection switch 650, which indicates that the lock tongue assembly 200 has reached the unlocked state at this time, and the controller 630 outputs a stop signal to the drive motor 410 to stop the drive motor 410.

[0124] On this basis, referring to Figures 2 to 18 , the lock body further includes: a fourth detection switch 660;

The fourth detection switch 660 is signal-connected to the controller 630. That is, the fourth detection switch 660 is used to detect whether the safety tongue assembly 930 is in the state of extending out of the housing 100 and feedback this information to the controller 630; if the fourth detection switch 660 detects the second detection block 932, the safety tongue assembly 930 is in the state of extending out of the housing 100, which means the door body is in the open state; if the fourth detection switch 660 fails to detect the second detection block 932, the safety tongue assembly 930 retracts into the housing 100, which means the door body is in the closed state. The controller 630 can control the start of the drive motor 410 according to the signals fed back by the third detection switch 650 and the fourth detection switch 660. For example, when the door body is closed, the third detection switch 650 corresponds to the third detection boss 360, and the fourth detection switch 660 switches from detecting the second detection block 932 to not detecting the second detection block 932, which means the door body has just been closed at this time and the locking tongue assembly 200 is in the unlocked state. At this time, a door locking instruction needs to be executed, and the controller 630 will start the drive motor 410 to make the drive motor 410 rotate forward, so as to drive the locking tongue steering wheel 310 to rotate forward through the first transmission mechanism 420, and make the locking tongue steering wheel 310 drive the locking tongue assembly 200 to move from the unlocked state to the locked state, achieving the purpose of automatic door locking.
