DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Combination Figures 1 to 6 As shown, the padlock of this embodiment includes a lock body 1, a lock hook 2, a lock core 3, a circuit frame 4, a motor 5, a battery 6, a circuit board 7 and a fingerprint touch panel 8. Figure 1 The left end of the lock hook 2 is arranged inside the lock body 1 as a connecting end, and is slidably connected with the lock body 1 in a vertical direction through a lock hook spring 9. The end of the lock hook 2 is provided with a lock hook groove 10 and can rotate relative to the lock body 1. Figure 1 The right end of the lock hook 2 shown in the figure can be inserted into the lock body hole 11 of the lock body 1 along the vertical direction as a locking end. Figure 1 The lock core 3 is shown as a horizontal slide arranged inside the lock body 1, and a lock core spring 12 is arranged between the lock core 3 and the lock body 1. The lock core spring 12 can drive the lock core 3 to move relative to the lock body 1 until the left end of the lock core 3 is inserted into the lock hook groove 10 of the lock hook 2, so as to restrict and hold the lock hook 2 in the insertion hole 11 of the lock body, that is, Figure 1 Position status shown.

[0021] The motor 5, the battery 6 and the circuit board 7 are electrically connected and arranged in the circuit frame 4, and the circuit frame 4 is detachably arranged in the lock body 1. The fingerprint touch panel 8 is arranged in the circuit frame 4 at an external position of the lock body 1 and is electrically connected to the circuit board 7. The output shaft 13 of the motor 5 can be connected to the right end of the lock cylinder 3 to drive the lock cylinder 3 to overcome the lock cylinder spring 12 and move to be disconnected from the lock hook groove 10, thereby completing the unlocking of the padlock.

[0022] In the padlock of this embodiment, the motor, battery, and circuit board are all arranged in a circuit frame, and the circuit frame is then detachably arranged inside the lock body, so that the electronic control part of the padlock can be modularized. In this way, when disassembly and assembly are required for maintenance, the entire padlock can be disassembled and assembled, which is convenient for replacement and maintenance of the circuit part, and the modular part can also be quickly mass-produced to improve production efficiency.

[0023] Combination Figure 1 and Figure 2 As shown, in the padlock of this embodiment, an anti-disassembly plate 14, a positioning pin 15 and a motor spring 16 are also provided inside the circuit frame 4. The positioning pin 15 is arranged on the circuit frame 4 and is located above the circuit board 7. The anti-disassembly plate 14 is a T-shaped structure, and the horizontal plate of the anti-disassembly plate 14 is arranged on the inner side of the circuit board 7 along the horizontal direction, and the fingerprint touch panel 8 is arranged on the outer side of the circuit board 7 along the horizontal direction. Figure 1 The right end of the middle horizontal plate is rotatably arranged with the circuit frame 4, and the left end of the horizontal plate can be inserted between the positioning pin 15 and the circuit board 7 in the horizontal direction. The free end of the vertical plate in the anti-disassembly plate 14 is provided with an inclined anti-disassembly arc surface 17, and the anti-disassembly arc surface 17 can lift the motor 5 upward to keep the motor 5 connected with the lock cylinder 3, that is, Figure 1The motor spring 16 is located between the motor 5 and the circuit frame 4 to drive the motor 5 to move downward so that the output shaft 13 of the motor 5 is disconnected from the lock core 3. At this time, when the fingerprint touch panel 8 on the surface of the lock body 1 is deformed by external force, the deformation can cause the circuit board 7 to bend and push the horizontal plate of the anti-disassembly plate 14 to deform upward and rotate over the positioning pin 15, thereby driving the anti-disassembly arc surface 17 to rotate to release the support of the motor 5, so that the motor 5 moves downward under the action of the motor spring 16 and is disconnected from the lock core 3.

[0024] In the padlock of this embodiment, by arranging an anti-disassembly plate, a positioning pin and a motor spring in the circuit frame, when the fingerprint touch panel is damaged by external violent squeezing, prying or other means, the fingerprint touch panel will push the anti-disassembly plate to overcome the rotation of the positioning pin, thereby releasing the limit of the motor. Under the action of the motor spring, the motor will automatically and quickly disconnect from the lock core, keeping the padlock in a locked state, thereby improving the safety of the padlock.

[0025] Among them, in this embodiment, the positioning pin 15 adopts a cylindrical structure, so that the outer arc surface of the positioning pin 15 forms a rotation restriction on the anti-disassembly plate 14 in the normal state, so that the anti-disassembly plate 14 can smoothly and quickly pass over the positioning pin 15 when it is pushed upward, thereby improving the reaction speed. In addition, a motor frame 28 and a circuit frame groove 47 are also provided on the outer surface of the motor 5. The motor frame 28 and the circuit frame groove 47 are slidably connected in the vertical direction, and the motor frame 28 is directly in contact with the anti-disassembly arc surface 17, so that the motor frame 28 with a more regular appearance is used to maintain an effective and reliable connection with the anti-disassembly arc surface 17, thereby preventing the motor 5 from accidentally slipping, and the motor spring 16 is directly connected to the motor frame 28.

[0026] In addition, combined Figure 1 As shown, in this embodiment, the fingerprint touch panel 8 is arranged Figure 1 The position on the left side of the circuit frame 4 shown makes the fingerprint touch panel 8 close to the end of the anti-disassembly plate 14 that abuts against the positioning pin 15, so that the deformation caused by the damage to the fingerprint touch panel can be quickly transmitted to the anti-disassembly plate 14, thereby improving the response speed of the anti-disassembly plate 14.

[0027] In addition, a charging interface 44 is also provided on the circuit frame 4 of the present embodiment. The charging interface 44 is located on one side of the fingerprint touch panel 8 and is connected to the circuit board 7 for charging the battery 6.

[0028] Combination Figure 1 and Figure 4As shown, in the padlock of this embodiment, a blocking screw 19 is further provided, and the lock body hole 11 is in the form of a stepped hole and is provided with a positioning surface 20. The blocking screw 19 is provided in the lock body hole 11, and the blocking screw 19 can be positioned on the positioning surface 20 and threadedly connected with the circuit frame 4, thereby fixing the circuit frame 4 in the lock body 1.

[0029] In the padlock of this embodiment, by providing a threaded hole aligned with the lock body hole on the circuit frame, the circuit frame and the lock body can be fixedly connected by providing a blocking screw in the lock body hole. In this way, after the padlock is opened and the lock hook is separated from the lock body hole, the circuit frame can be disassembled by rotating the blocking screw, thereby achieving fast and safe disassembly and maintenance.

[0030] Combination Figure 1 and Figure 4 As shown, in the padlock of this embodiment, a blocking sleeve 21 and a blocking pin 22 are also provided. The blocking sleeve 21 is slidably arranged in the lock body hole 11, and a blocking spring 18 is arranged above the blocking sleeve 21, and the blocking spring 18 can drive the blocking sleeve 21 to move downward, and a concave arc surface is arranged at the lower end of the blocking sleeve 21. A motor shaft hole 23 is arranged on the lock body 1, and the output shaft 13 of the motor 5 can pass through the motor shaft hole 23 to form a connection with the lock core 3, and the blocking pin 22 is slidably arranged between the motor shaft hole 23 and the lock body hole 11 in the horizontal direction.

[0031] When the padlock is damaged by violence, that is, the motor 5 moves downward under the action of the motor spring 16 and falls into the circuit frame 4, the output shaft 13 falls with the motor 5 and is disconnected from the lock core 3 and exits the motor shaft hole 23, and the blocking spring 18 can push the blocking sleeve 21 to move downward and push the blocking pin 22 to move forward through the concave arc surface. Figure 4 The motor shaft hole 23 is moved in the left direction as shown, the motor shaft hole 23 is blocked, and the blocking pin 22 is restricted by the outer surface of the blocking pin 22 to extend into the lock body hole 11, so that even after the components in the circuit frame 4 are removed, they cannot be connected to the lock core 3 through the motor shaft hole 23, so that the padlock continues to remain in the locked state, further improving the safety and reliability of the padlock when it is violently damaged. In this embodiment, the blocking screw 19 passes through the blocking sleeve 21 and is connected to the circuit frame 4, and the blocking spring 18 is arranged between the blocking screw 19 and the blocking sleeve 21.

[0032] Combination Figures 1 to 6As shown, in the padlock of this embodiment, a control plate 24, a connecting plate 25 and a control spring 26 are further provided, and a motor shaft groove 27 arranged radially is provided on the output shaft 13 of the motor 5, and the motor shaft groove 27 is a conical structure. A central hole is provided on the control plate 24, one end of the connecting plate 25 is slidably arranged on the control plate 24 through the control spring 26 as a connecting end, and the other end of the connecting plate 25 is a free end with a conical structure that can be inserted into the motor shaft groove 27, and the output shaft 13 of the motor 5 can be inserted into the central hole of the control plate 24.

[0033] After the output shaft 13 of the motor 5 extends into the center hole of the control board 24, the control spring 26 can push the free end of the connecting plate 25 to extend into the motor shaft groove 27, connecting the control board 24 to the output shaft 13 of the motor 5, so that synchronous rotation can be achieved, and then the control board 24 pushes the lock core 3 to overcome the lock core spring 12 to move. When the motor 5 moves downward, the motor shaft groove 27 can push the connecting plate 25 to overcome the control spring 26 and shrink into the control board 24, so that when the output shaft 13 moves downward and moves out of the center hole of the control board 24, the connection between the motor 5 and the control board 24 is released.

[0034] In this embodiment, a connecting plate is provided in the control board, and the connecting plate and the output shaft cooperate so that when the output shaft of the motor is inserted into the control board, the output shaft of the motor can drive the control board to rotate, so that the motor can be plug-and-play, ensuring the overall modularization of the circuit part, and the installation is convenient and quick, thereby improving the assembly efficiency.

[0035] Combination Figure 6 As shown, in this embodiment, the motor shaft groove 27 in the form of a tapered groove has a first inclined surface 29 located in a vertical plane, and the connecting plate 25 has a second inclined surface 30 located in a vertical plane. When the motor 5 moves downward, the first inclined surface 29 and the end of the connecting plate 25 can be used to push the connecting plate 25 to overcome the control spring 26 and shrink into the control plate 24, thereby releasing the connection between the motor 5 and the control plate 24. Conversely, when the motor 5 moves upward, under the interaction between the top of the output shaft 13 and the second inclined surface 30, the output shaft 13 can push the connecting plate 25 to overcome the contraction of the control spring 26, so that the output shaft 13 can be smoothly inserted into the center hole of the control plate 24, and under the action of the restoring force of the control spring 26, the connecting plate 25 can be extended into the motor shaft groove 27 again.

[0036] Combination Figure 1 , Figure 3 and Figure 5 As shown, in the padlock of this embodiment, a locking rod 31 is further provided. The locking rod 31 is rotatably arranged in the lock body 1, and a locking rod plate 32 is provided at the upper end of the locking rod 31. The locking rod 31 can drive the locking rod plate 32 to rotate, so as to drive the lock core 3 to overcome the lock core spring 12 to move.

[0037] In this embodiment, a lock rod is provided, which can be used to drive the lock core to move. Therefore, when the motor cannot drive the lock core to unlock, the lock rod can also be used to unlock the padlock, thereby improving the practicality of the padlock.

[0038] Combination Figure 1 , Figure 3 and Figure 5 As shown, in the padlock of this embodiment, a rotating rod 33 and a password ring 34 are further provided, and a lock body vertical groove 35 is provided on the lock body 1. The rotating rod 33 is slidably arranged on the lock body 1 in the vertical direction, and the lower end of the lock rod 31 and the upper end of the rotating rod 33 are slidably connected in the vertical direction through a flat key. A telescopic spring 46 is further provided between the rotating rod 33 and the lock rod 31, and a radially extending lock block 45 is provided on the outer surface of the rotating rod 33. The password ring 34 is sleeved on the outer side of the rotating rod 33 and can rotate relative to the lock body 1 and the rotating rod 33. The password ring 34 is provided with a ring groove 36 and a lock groove 37 located in adjacent cross sections.

[0039] The rotating rod 33 can overcome the telescopic spring 46 and move relative to the lock body 1 and the lock rod 31 in the vertical direction until the lock block 45 is located in the annular groove 36 and extends into the lock body vertical groove 35 to limit the rotation of the rotating rod 33. Figure 5 The code ring 34 can rotate relative to the rotating rod 33, so that the lock block 45 slides relatively in the ring groove 36 until it is aligned with the lock groove 37, so that the telescopic spring 46 pushes the rotating rod 33 to move downward relative to the lock body 1 and the lock rod 31, so that the lock block 45 entering the lock body vertical groove 35 is separated from the lock body vertical groove 35 and enters the lock groove 37, thereby releasing the rotation restriction of the rotating rod 33, so that the rotating rod 33 can drive the lock rod 31 to rotate, so as to drive the lock core 3 to move.

[0040] In this embodiment, through the password ring and the vertical groove of the lock body, the password ring can be used to control the movement of the lock rod to achieve password unlocking, thereby adding a new unlocking method.

[0041] Combination Figure 1 and Figure 5 As shown, in the padlock of this embodiment, four password rings 34 are specifically provided, and the four password rings 34 are sequentially arranged along the axial direction of the rotating rod 33, and can rotate relative to the lock body 1 and the rotating rod 33 respectively. At the same time, four locking blocks 45 are arranged on the rotating rod 33, and each password ring 34 is provided with a ring groove 36 and a lock groove 37. Among them, the topmost locking block 45 is responsible for plugging and connecting with the vertical groove 35 of the lock body.

[0042] At this time, by setting multiple password rings, the telescopic spring can push the rotating rod to move downward and disengage from the vertical slot of the lock body only after all the password rings are rotated into place, that is, each lock slot is aligned with the corresponding lock block, thereby further improving the safety and reliability of the padlock. Of course, in other embodiments, the number of password rings and the number of corresponding lock blocks can be freely adjusted according to usage and design requirements to achieve different control effects.

[0043] Combination Figure 1 As shown, in the padlock of this embodiment, the connecting end of the lock hook 2 is also provided with a lock hook annular groove 38. When the control end of the lock hook 2 moves out of the lock body hole 11, the lock core spring 12 pushes the lock core 3 into the lock hook annular groove 38, and the lock core 3 can slide relatively along the lock hook annular groove 38, thereby ensuring that the lock hook 2 can rotate freely.

[0044] Combination Figures 1 to 6 As shown, in the padlock of this embodiment, a lock core slider 39 is also provided, and the depth of the lock hook groove 10 is equal to the depth of the lock hook annular groove 38. At the same time, along the moving direction of the lock core 3 relative to the lock body 1, that is, Figure 1 In the horizontal direction shown, the lock body 1 is provided with a lock body flat groove 40, the lock core slider 39 is provided with a lock core pin 41, the free end of the lock core pin 41 is slidably arranged in the lock body flat groove 40, the lock core 3 has a first lock core plate 42 and a second lock core plate 43, the lock core spring 12 is located between the first lock core plate 42 and the lock core slider 39, and the control board 24 is located on the side of the lock core slider 39 away from the lock core spring 12, that is, Figure 3 At the right end of the lock core slider 39, the second lock core plate 43 is also located on the side of the lock core slider 39 away from the lock core spring 12, so that the rotation of the control plate 24 can push the second lock core plate 43 to move the lock core 3 to overcome the lock core spring 12. When the lock core 3 is inserted into the lock hook annular groove 38, the output shaft 13 of the motor 5 can be inserted into the center hole of the control plate 24, that is, the center hole of the control plate 24 is aligned with the motor shaft hole 23.

[0045] In this embodiment, by setting a lock core slider between the first lock core plate and the second lock core plate of the lock core, the lock core can be driven to move by utilizing the control plate and the lock rod plate to act on the two lock core plates respectively, and the depth of the lock hook groove and the depth of the lock hook annular groove are set equal, so that the motor shaft hole and the center hole of the control plate can be kept aligned to ensure that the output shaft of the motor can be inserted into the center hole of the control plate and form an effective connection with the control plate.

[0046] Combination Figures 1 to 6 As shown, the working process of the padlock in this embodiment is as follows: When the padlock of this embodiment needs to be opened, Figure 1When the padlock in the position shown is opened, the correct fingerprint is pressed on the fingerprint touch panel 8. After the fingerprint touch panel 8 is correctly identified, the motor 5 starts to rotate, and the control panel 24 is driven by the connecting plate 25. Figure 3 As shown in the clockwise direction, the control panel 24 is turned Figure 3 The second lock core plate 43 is pushed in the right direction as shown, and the second lock core plate 43 moves the lock core 3 to the right with the lock core 3, overcoming the lock core spring 12. At this time, the lock core pin 41 is located at the rightmost end position of the lock body flat groove 40, and the lock core slider 39 remains in position, so that the lock core 3 is moved out of the lock hook groove 10, releasing the restriction on the lock hook 2, so that the lock hook spring 9 pushes the lock hook 2 to move upward and disengage from the lock body hole 11, and the lock hook 2 is rotated to complete the unlocking operation of the padlock.

[0047] When the electric control component of the padlock of this embodiment is damaged and needs to be replaced and maintained, the four code rings 34 are rotated to make the lock block 45 on the rotating rod 33 slide relatively in the corresponding ring groove 36, so that the lock block 45 Figure 5 The lock grooves 37 on the four code rings 34 are rotated to the bottom of the corresponding lock blocks 45, and the code rings 34 lose their support for the lock blocks 45. The telescopic spring 46 pushes the rotating rod 33 to move downward, and the uppermost lock block 45 moves out of the vertical groove 35 of the lock body, releasing the rotation restriction of the rotating rod 33, driving the rotating rod 33 to rotate with the lock rod 31, so that the lock rod plate 32 moves along the vertical groove 35 of the lock body. Figure 3 The first lock core plate 42 is pushed in the right direction as shown, and the first lock core plate 42 brings the lock core 3 to overcome the lock core spring 12 and move to the right, so that the lock core 3 is moved out of the lock hook groove 10, releasing the restriction on the lock hook 2, so that the lock hook spring 9 pushes the lock hook 2 to move upward and disengage from the lock body hole 11, and the lock hook 2 is rotated to complete the unlocking operation of the padlock.

[0048] After unlocking is completed by the locking rod 31, the lock body hole 11 is exposed, the blocking screw 19 is rotated to release the connection with the circuit frame 4 and removed, and then the blocking spring 18 and the blocking sleeve 21 are taken out from the lock body hole 11, and the circuit frame 4 is pushed downward through the lock body hole 11, and the circuit frame 4 is pushed out of the lock body 1, and the motor 5 is moved downward with the circuit frame 4, and the connecting plate 25 is pushed by the first inclined surface 29 to overcome the control spring 26 and shrink into the control board 24, thereby releasing the connection between the motor 5 and the control board 24, so that the motor 5 can be removed together with the circuit frame 4, and the disassembly of the circuit part is completed.

[0049] After the disassembly is completed, the lock core 3 is located in the lock hook annular groove 38. Since the depth of the lock hook groove 10 is equal to the depth of the lock hook annular groove 38, the position of the control board 24 remains unchanged, and the center hole of the control board 24 remains aligned with the motor shaft hole 23. When the circuit frame 4 is pushed into the lock body 1, the blocking pin 22 remains in the position in which the circuit frame 4 is pushed into the lock body 1. Figure 4 In the position shown, the motor shaft hole 23 remains in a through state, and the output shaft 13 of the motor 5 can pass through the motor shaft hole 23 and enter the center hole of the control board 24. The output shaft 13 and the second inclined surface 30 push the connecting plate 25 to overcome the control spring 26 and retract into the control board 24 again, so that the output shaft 13 of the motor 5 is fully inserted and the motor shaft groove 27 is aligned with the connecting plate 25. The control spring 26 pushes the connecting plate 25 to extend into the motor shaft groove 27 again and remain in it, completing the reconnection of the motor 5 and the control board 24. Thereafter, the blocking sleeve 21 and the blocking spring 18 are placed in the lock body hole 11, the blocking screw 19 is passed through the blocking sleeve 21 to connect with the circuit frame 4, and the circuit frame 4 is re-fixed in the lock body 1 to complete the replacement and installation of the new electric control component.

[0050] When the fingerprint touch panel 8 or the charging port 44 is violently squeezed and pried open, the circuit board 7 is deformed by the inward force, causing the left end of the anti-disassembly plate 14 to be damaged or bent and deformed and to be out of the restriction of the positioning pin 15, causing the anti-disassembly plate 14 to flip over, and the anti-disassembly arc surface 17 loses the support for the motor 5, so that the motor 5 moves downward under the action of the motor spring 16 and is out of the connection with the control board 24, thereby falling into the circuit frame 4, and the output shaft 13 of the motor 5 is pulled out of the motor shaft hole 23, and the blocking spring 18 pushes the blocking sleeve 21 to move downward, and the blocking sleeve 21 pushes the blocking pin 22 to Figure 4 As shown in the figure, the blocking sleeve 21 moves in the left direction and extends into the motor shaft hole 23. At the same time, the blocking sleeve 21 moves downward to the right side of the blocking pin 22, limiting the blocking pin 22 to a position where it extends into the motor shaft hole 23, thereby cutting off the motor shaft hole 23. Even if the circuit components in the circuit frame 4 are removed, they cannot be connected to the control board 24, so that the padlock of this embodiment is always kept in a locked state and can only be unlocked by the password ring 34.
