[0082] When the key is dropped, the owner sends a signal to the communicator, and the controller controls the power supply 31 to supply power to the locking assembly 6 after receiving the signal of the communicator, so that the first motor 61 drives the fork wheel 62 to rotate, and the lever 631 of the clamping piece 63 is pushed when the fork wheel 62 rotates, thereby the lever 633 of the clamping piece 63 rotates to the position between the lock head cam 44 and the clamping tooth 521, and the rotation of the lock head cam 44 is hindered to the clamping tooth 521, thereby the unlocking path of the lock head cam 44 is blocked, the first convex part 441 cannot rotate to abut against the clamping tooth 521, thereby the displacement of the clamping tooth 521 cannot be caused, and the anti-theft is realized.

[0083] It should be noted that the controller and the communicator in the application can be selected from common controllers and communicators on the market, and are not limited. The PCB line plate 25 is provided with a plurality of electronic elements such as capacitors and resistors, thereby a control circuit is formed with the controller, and a communication circuit is formed with the communicator, and the control circuit and the communication circuit are both existing control circuits and communication circuits on the market.

[0084] Referring to Figure 2 , Figure 4 and Figure 5 , the power supply assembly 3 further comprises a charging group, the charging group is electrically connected with the power supply 31 through the PCB line plate 25, the charging group comprises the first charging tongue 32 and the second charging tongue 33, the power supply 31 is electrically connected with the first charging tongue 32 and the second charging tongue 33, and the first charging tongue 32 and the second charging tongue 33 respectively pass through the first charging hole 231 and the second charging hole 232 of the lock body; the first charging tongue 32 abuts against the charging buckle 14 of the buckle 1, the second charging tongue 33 abuts against the lock piece 11 of the buckle 1, and the controller controls the power supply 31 to realize charging;

[0085] The charging set further comprises a first tongue seat 34, a second tongue seat 35, a first return spring 36 and a second return spring 37. The first return spring 36 is accommodated in the first tongue seat 34, the first charging tongue 32 is installed in the first tongue seat 34, and the first charging tongue 32 abuts against the first return spring 36. The second return spring 37 is accommodated in the second tongue seat 35, the second charging tongue 33 is installed in the second tongue seat 35, and the second charging tongue 33 abuts against the second return spring 37.

[0086] By arranging the charging buckle 14 on the buckle seat 1 and arranging the first charging tongue 32 and the second charging tongue 33 on the power supply assembly 3, when the door is closed, the first charging tongue 32 abuts against the charging buckle 14, and the second charging tongue 33 abuts against the lock piece 11. At this time, the controller can control the power supply 31 to realize charging.

[0087] Since the first charging tongue 32 and the second charging tongue 33 pass through the first charging hole 231 and the second charging hole 232 of the guide plate 23 respectively, the first charging tongue 32 and the second charging tongue 33 will affect the closing of the door. Therefore, the first charging tongue 32 and the second charging tongue 33 are arranged in the first tongue seat 34 and the second tongue seat 35 respectively, and abut against the first charging tongue 32 and the second charging tongue 33 through the first return spring 36 and the second return spring 37 respectively, so that the first charging tongue 32 and the second charging tongue 33 can retract into the lock shell 2 when the door is closed, avoiding the influence of the first charging tongue 32 and the second charging tongue 33 on the closing of the door. At the same time, when the door is opened, the first charging tongue 32 and the second charging tongue 33 can extend out of the lock shell 2 under the action of the first return spring 36 and the second return spring 37. It should be noted that the corresponding charging buckle 14 also has the same structure, so that the charging buckle 14 can retract into the buckle seat 1 when the door is closed, and extend out of the charging hole 113 when the door is opened.

[0088] It should be noted that the buckle seat 1 further comprises a circuit board 15, and the magnetic inductor 13, the first charging tongue 32 and the second charging tongue 33 can be integrated on the circuit board 15. The first charging tongue 32 and the second charging tongue 33 can be connected to household wires. It can be understood that the circuit board 15 further integrates other electronic elements, which can be used for voltage conversion and the like.

[0089] Referring to Figure 2 , Figure 4 and Figure 5As shown, the voice broadcast speaker 24 is fixed on the bottom plate assembly 21, and the voice broadcast speaker 24 is electrically connected with the controller through the PCB circuit board 25. Since the voice broadcast speaker 24 is arranged, the voice broadcast speaker 24 is used to emit a prompt sound when unlocking, locking and locking, and the prompt sound is used to remind the user to understand the state of the anti-theft intelligent lock. The broadcast content of the voice broadcast speaker 24 is set by the controller. The bottom plate assembly 21 further comprises a voice broadcast speaker guard plate 214, which is fixed by screws so that the voice broadcast speaker 24 covers the top of the voice broadcast speaker 24 to protect the voice broadcast speaker 24 from being damaged.

[0090] Referring to Figure 2 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown, the transmission assembly 9 comprises a shaft body fixed on the bottom plate assembly 21, a first transmission gear 91, a rack dial 92, a lock wheel gasket 93 and a second transmission gear 94 which are sequentially sleeved on the shaft body from top to bottom.

[0091] The bottom of the first transmission gear 91 is provided with a groove 911.

[0092] The rack dial 92 is provided with a first protrusion 921, a dialing part 922 and a second protrusion 923. The first protrusion 921 is arranged at the top of the rack dial 92, the dialing part 922 is arranged at the outer periphery of the rack dial 92, the dialing part 922 is in abutment with the displacement part 511 of the square tongue 51, the first protrusion 921 is accommodated in the groove 911, and the first protrusion 921 can rotate in the groove 911.

[0093] The lock wheel gasket 93 is provided with a clutch hole 931, a driving column 932 and a notch 933. The clutch hole 931 is arranged in the center hole of the lock wheel gasket 93. The driving column 932 is arranged at the outer periphery of the lock wheel gasket 93, and the driving column 932 is in abutment with the side surface of the dialing part 922. The notch 933 is arranged at the outer periphery of the lock wheel gasket 93, and the notch 933 corresponds to the position of the second protrusion 923. The second protrusion 923 can rotate in the notch 933.

[0094] The transition gear 81 is arranged between the transmission assembly 9 and the gear box 8. The first transmission gear 91 is engaged with the transition gear 81, and the transmission assembly 9 and the gear box 8 are drivingly connected through the transition gear 81.

[0095] The second transmission gear 94 is engaged with the sawtooth 522 of the rack 52. The top of the second transmission gear is provided with a third protrusion 941, which is accommodated in the clutch hole 931, and the third protrusion 941 can rotate in the clutch hole 931.

[0096] The bottom plate assembly 21 comprises a torsion column 211 and a torsion spring 212 sleeved on the torsion column 211, the pin of the torsion spring 212 passes through the perforation of the rack dial 92, and the torsion spring 212 controls the rack dial 92 to reset.

[0097] The gear box 8 provides power to rotate the transition gear 81 to the second direction, so as to rotate the first transmission gear 91 to the second direction, and thus the groove 911 is also rotated, and since the first protrusion 921 abuts against one side of the groove 911, the first protrusion 921 is driven to move, so as to make the rack dial 92 abut against the displacement part 511 of the square tongue 51, and after abutting, the square tongue 51 is driven to retract into the lock shell 2.

[0098] The handle unlocking assembly 7 rotates to the first direction, so as to drive the second transmission gear 94 to rotate to the first direction through the handle gear sheet 76, so as to make the square tongue 51 extend out of the lock shell 2, and since the lock wheel gasket 93 is provided with the clutch hole 931, but the length of the clutch hole 931 is greater than the width of the third protrusion 941, the lock wheel gasket 93 is driven to rotate to the first direction with a lag; and since the length of the notch 933 of the lock wheel gasket 93 is greater than the width of the second protrusion 923 of the rack dial 92, the rack dial 92 is driven to rotate to the first direction with a lag.

[0099] Since the displacement part 922 of the rack dial 92 can abut against the displacement part 511 to drive the square tongue 51 to retract when rotating, in order to continue to drive the square tongue 51 to retract through the rack dial 92 next time, the pin of the torsion spring 212 passes through the perforation of the rack dial 92, so as to reset the rack dial 92.

[0100] Referring to Figure 2 , Figure 4 , Figure 5 and Figure 10 , the gear box 8 comprises a gear box bottom shell 82 fixed on the bottom plate assembly 21, a gear box upper shell 83 installed on the gear box bottom shell 82, a second motor 84 installed on the gear box bottom shell 82, a first gear 85, a second gear 86, a third gear set and a fourth gear set installed between the gear box bottom shell 82 and the gear box upper shell 83 through a center shaft, the fourth gear set is an output gear of the gear box 8, and the second motor 84 is electrically connected with the power assembly 3.

[0101] The output shaft of the second motor 84 is further sleeved with a motor gear 89, the central shaft of the second gear 86 is further fixed with a second secondary gear 861, the third gear set comprises a third first gear 871 and a third second gear 872 rotating synchronously, the central shaft of the third first gear 871 is further fixed with a third first secondary gear 8711, the central shaft of the third second gear 872 is further fixed with a third second secondary gear 8721, the fourth gear set comprises a fourth first gear 881, a fourth second gear 882 and a fourth third gear 883 rotating synchronously, the central shaft of the fourth first gear 881 is further fixed with a fourth secondary gear 8811, the central shaft of the fourth second gear 882 is further fixed with a fourth chamfered triangular gear 8821, the fourth third gear 883 is provided with a fixed hole 8831 penetrating through the center thereof and consistent with the shape of the outer periphery of the fourth chamfered triangular gear 8821;

[0102] The gear box upper shell 83 is provided with a through hole corresponding to the fourth gear set, the central shaft of the fourth gear set passes through the through hole, and the fourth third gear 883 is exposed from the gear box upper shell 83;

[0103] The motor gear 89 is engaged with the first gear 85, the first gear 85 is engaged with the second gear 86, the second secondary gear 861 is engaged with the third first gear 871, the third first secondary gear 8711 is engaged with the fourth first gear 881, the third second gear 872 is engaged with the fourth secondary gear 8811, the third second secondary gear 8721 is engaged with the fourth second gear 882, and the fourth third gear 883 is engaged with the transition gear 81.

[0104] Referring to Figure 2 , Figure 4 , Figure 5 and Figure 7As shown, the handle unlocking assembly 7 comprises a mounting seat 72 fixed to the bottom plate assembly 21, a handle cam 73 penetrating the mounting seat 72, a handle upper push piece 74, a handle washer 75 and a handle gear piece 76 which are sequentially sleeved on the handle cam 73; the handle cam 73 is centrally provided with a square hole for mounting the handle, and the outer periphery of the handle cam 73 is provided with a protruding portion 731; the handle upper push piece 74 is centrally penetrated with a first assembly hole 741 which is consistent with the shape of the outer periphery of the handle cam 73, and the bottom of the handle upper push piece 74 is provided with a semicircular ring portion 742 which is used to push the latch catch 71 to deviate when the handle upper push piece 74 rotates; the handle washer 75 is centrally penetrated with a second assembly hole 751 which is consistent with the shape of the outer periphery of the handle cam 73, and the handle washer 75 extends a first cantilever 752, a second cantilever 753 and a third cantilever 754, and the first cantilever 752 and the second cantilever 753 are downwardly bent; the handle gear piece 76 is centrally provided with a third assembly hole 761 which is provided with a surplus hole 762 at the corresponding position of the protruding portion 731, and the handle gear piece 76 extends a gear arm 763, a third shoulder arm 764 and a fourth shoulder arm 765, the gear arm 763 is engaged with the transmission assembly 9, and the fourth shoulder arm 765 is fixedly connected with the double torsion spring 213 of the bottom plate assembly 21.

[0105] Since the shapes of the first assembly hole 741 and the second assembly hole 751 are consistent with the shape of the outer periphery of the handle cam 73, when the handle cam 73 is rotated in the first direction, the handle upper push piece 74 and the handle washer 75 will be coaxially rotated, and the handle upper push piece 74 can push the latch catch 71 to deviate through the semicircular ring portion 742 when the handle upper push piece 74 rotates, and the deviated latch catch 71 stops applying force to the shaft push block 107, so that the latch catch 71 is simultaneously clamped into the accommodating groove 1011 and the clamping groove 1021, thereby achieving the locking of the latch assembly 10.

[0106] When the handle cam 73 rotates in the first direction, the convex part 731 will abut against one end of the remaining hole 762, driving the handle gear sheet 76 to rotate, and the gear teeth arm 763 of the handle gear sheet 76 will drive the second transmission gear 94 to rotate, thereby causing the rack 52 to displace, driving the square tongue 51 to extend out of the square tongue guide hole 233. After completion, the double torsion spring 213 fixedly connected with the fourth shoulder arm 765 will drive the handle gear sheet 76 to reset, and the remaining hole 762 has a remaining space for the convex part to rotate, so that the handle gear resetting process causes the handle cam 73 to rotate in the second direction. Since the rack 52 is provided with a sliding groove 523, the resetting of the handle gear sheet 76 will not cause the square tongue 51 to retract into the lock shell 2. Since the length of the sliding groove 523 is greater than the extension length of the square tongue 51, after the square tongue 51 extends out of the square tongue guide hole 233, the handle cam 73 rotates in the second direction, and the rack 52 will move in the unlocking direction. However, after the handle cam 73 is rotated completely, the outer end of the sliding groove 523 of the rack 52 cannot abut against the fixed part 512, so the square tongue 51 cannot be retracted. Therefore, the handle unlocking assembly 7 can complete the locking of the square tongue assembly 5, but cannot complete the unlocking of the square tongue assembly 5.

[0107] Referring to Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the latch assembly 10 comprises a latch body 101, a latch positioning member 102, a latch push block 103, a return spring 104, a latch shaft 105, a shaft spring 106, a shaft push block 107 and a latch baffle 108; the latch body 101 is provided with a receiving groove 1011, the latch shaft 105 is provided with a clamping portion 1051, the latch shaft 105 is accommodated in the receiving groove 1011, the latch positioning member 102 is provided with a clamping groove 1021 on the side close to the latch body 101, the shaft spring 106 is sleeved on the latch shaft 105, one end of the shaft spring 106 abuts against the clamping portion 1051, and the other end of the shaft spring 106 is fixedly connected with the shaft push block 107; the clamping portion 1051 is clamped in the receiving groove 1011 and the clamping groove 1021, so as to lock the latch assembly 10; the latch baffle 71 is clamped in the clamping groove 1021, the latch baffle 71 abuts against the shaft push block 107 and makes the clamping portion 1051 of the latch shaft 105 completely accommodated in the receiving groove 1011 through the shaft spring 106, so as to unlock the latch assembly 10; the latch push block 103 abuts against the latch body 101 and the latch positioning member 102, and the latch push block 103 is fixedly connected with the latch positioning member 102; the latch baffle 108 surrounds the latch body 101, the latch positioning member 102, the latch push block 103, the return spring 104 and the latch shaft 105; the latch body 101 is provided with a magnet 1012, and the buckle seat 1 further comprises a magnetic sensor 13, which is arranged in the latch hole 112 and used for sensing the magnet 1012 of the latch body 101.

[0108] When the latch assembly 10 is in the locked state, the clamping portion 1051 of the latch shaft 105 is clamped in the receiving groove 1011 and the clamping groove 1021 without the latch baffle 71 pressing the latch shaft 105, and the latch body 101 cannot swing and cannot be retracted into the lock shell 2 because the latch positioning member 102 is fixedly connected with the latch push block 103.

[0109] When the latch assembly 10 is in the unlocked state, the latch baffle 71 presses the shaft push block 107, and the force is transmitted to the latch shaft 105 through the latch spring because one end of the shaft spring 106 abuts against the clamping portion 1051 and the other end of the shaft spring 106 is fixedly connected with the shaft push block 107, so that the clamping portion 1051 is completely accommodated in the receiving groove 1011, the connection between the latch body 101 and the latch positioning member 102 through the latch shaft 105 is released, and the latch body 101 can swing to complete the unlocking of the latch assembly 10.

[0110] It should be noted that the latch tongue shaft 105 is also provided with a clamping portion 1052, and the latch tongue assembly 10 further comprises a limiting pad 109 fixed in the accommodating groove 1011 corresponding to the clamping portion 1052, so as to prevent the latch tongue shaft 105 from falling off from the latch tongue body 101. The latch tongue body 101 is provided with a slope on both sides in the swing direction, so that when the latch tongue assembly 10 is unlocked, the latch tongue body 101 can swing out of the latch tongue hole 112 along with the opening of the door.

[0111] The latch tongue body 101 is provided with a magnet 1012, and the buckle seat 1 further comprises a magnetic sensor 13 arranged in the latch tongue hole 112. The magnetic sensor 13 is integrated on a circuit board 15 connected with a PCB circuit board 25, and is used for sensing the magnet 1012 of the latch tongue body 101. When the magnetic sensor 13 senses that the latch tongue body 101 is located in the latch tongue hole 112, a locking signal is sent to the controller; and when the magnetic sensor 13 does not sense that the latch tongue body 101 is located in the latch tongue hole 112, an unlocking signal is sent to the controller.

[0112] The above is only the preferred embodiment of the present application, and does not limit the technical scope of the present application. Any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical solution of the present application.
