Description

TECHNICAL FIELD

[0001] The present application relates to an intelligent padlock and a debugging method thereof. BACKGROUND

[0002] Padlocks are common in daily life. A ring-shaped or "I"-shaped metal rod, i.e., a "lock beam", is installed on the lock body, so that the padlock is directly connected with the lock body through the lock beam to form a closed lock. With the rapid development of wireless communication and intelligent technology, intelligent padlocks have appeared on the market in recent years. The intelligent padlock is a combination of traditional padlocks and modern intelligent technology, which realizes intelligent operation through fingerprint recognition, mobile phone APP control, anti-loss function, etc.

[0003] The intelligent padlock can be remotely unlocked by a mobile phone or other smart devices in cooperation with a special APP, i.e., without close proximity to the lock, as long as the smart device is remotely operated to unlock. In actual operation, the personnel with unlocking authority are usually separated from the personnel who actually open the lock, i.e., the personnel with unlocking authority are in the dispatch center and open the corresponding padlock as needed, while the personnel who open the lock are usually maintenance personnel. When the padlock is opened, the maintenance personnel can open the cabinet door where the padlock is located and maintain the equipment in the cabinet.

[0004] However, the existing intelligent padlock lacks a locking state feedback function, i.e., the personnel with unlocking authority cannot know whether the padlock has been truly opened in real time and accurately after operating the smart device and performing the unlocking action, but can only know it after communicating with the actual unlocking personnel who are close to the padlock. Therefore, the personnel with unlocking authority cannot effectively master the dynamic of the padlock, so the convenience and reliability of use are low. In addition, if the padlock fails or is damaged by personnel and is in an unlocked state, the personnel with unlocking authority cannot master the above situation in the first time, and thus cannot effectively monitor the real-time state of the intelligent padlock, so the security protection function is also weak and needs to be further improved.

[0032] In the locked state, one end of the locking strip 17 towards the rotating end 21 is inserted in the annular locking groove 21, when unlocking is needed, the user controls the matching operation end smart device to send a correct unlocking signal to the communication module 5, the communication module 5 sends an unlocking instruction to the chip 4 after receiving the correct unlocking signal, the chip 4 sends a power-on instruction to the battery 6 after receiving and processing the unlocking instruction, the battery 6 starts the micro motor 16 to work after receiving the power-on instruction, and then drives the locking strip 17 to horizontally move so that one end of the locking strip 17 towards the rotating end 21 leaves the annular locking groove 21, so that the rotating end 21 on the n-shaped lock hook 2 can move upwards until the swinging end 22 leaves the lock body 1, thus achieving unlocking, and the above principle is also prior art;

[0033] The feature of the present application is that the lock cylinder further comprises a core body 13, the micro motor 16 and the battery 6 are both fixed in the core body 13, the locking strip 17 is horizontally and movably embedded in one side of the core body 13 and above the micro motor 16, and the lock cylinder further comprises a press plate 18 detachably fixed on one side of the core body 13 and covering the micro motor 16 and the locking strip 17;

[0034] A position detection unit is further arranged between the press plate 18 and the locking strip 17, the position detection unit comprising a fan-shaped driving plate 111 horizontally and rotatably connected to one side of the locking strip 17 towards the inside of the press plate 18, a micro switch 15 fixed on the fan-shaped driving plate 111, and a straight-line rack 113 horizontally fixed on the inner wall of the press plate 18 and horizontally adjustable in position, the micro switch 15 being signal connected with the chip 4 and electrically connected with the battery 6, and the moving contact of the micro switch 15 being vertically upwards or downwards arranged;

[0036] The straight toothed rack 113 is transversely and movably connected to the inner wall of the pressing plate 18 to have a transverse translation function. Correspondingly, the pressing plate 18 is further connected with an adjusting bolt 114 which is transversely arranged and rotatable. The threaded end of the adjusting bolt 114 is inserted into the inner part of the proximal end of the straight toothed rack 113.

[0037] The locking strip 17 is provided with a clamping concave cavity 171 on the side outer wall facing the pressing plate 18. The fan-shaped driving plate 111 is transversely and rotatably connected to the inner part of the opening of the clamping concave cavity 171. The movable contact of the micro switch 15 cooperates with the upper or lower edge of the opening of the clamping concave cavity 171.

[0038] The rotating shaft of the micro motor 16 is vertically upwardly arranged. The rotating shaft of the micro motor 16 is further fixed with a concentrically arranged rotating disc 19. The top of the rotating disc 19 is further fixed with two vertically arranged and diagonally distributed traction columns 110. The lower side outer wall of the locking strip 17 is further formed with a stop block 172 downwardly. The two traction columns 110 are arranged between the stop block 172 and the rotating end 21 on the n-shaped lock hook 2.

[0039] The top of the core 13 is provided with a vertically arranged blind hole 131. The rotating end 21 is rotatably inserted into and axially movable along the blind hole 131. The side outer wall of the core 13 is provided with a transversely arranged and internally communicating guiding groove 132 with the blind hole 131. The locking strip 17 is transversely and movably embedded in the guiding groove 132.

[0040] The lower inner wall of the guiding groove 132 is provided with a limiting gap 133. The stop block 172 and the two traction columns 110 are movably arranged in the limiting gap 133.

[0041] The locking strip 17 is further provided with a return spring 14 between the end away from the rotating end 21 and the proximal side inner wall of the guiding groove 132. One end of the return spring 14 is embedded in the end of the locking strip 17 away from the rotating end 21. The other end of the return spring 14 is tightly pressed against the corresponding side inner wall of the guiding groove 132, so that the locking strip 17 always has a transverse movement tendency towards the rotating end 21 by the rebound force of the return spring 14.

[0042] A first slot hole 134 is formed between the bottom surface of the guide groove 132 and the other side outer wall of the core 13, and a corresponding open slot 173 is formed on the side outer wall of the locking strip 17 away from the pressing plate 18. A second slot hole 1101 is formed between the inner wall and the outer wall of the shell 11 on the side facing the first slot hole 134, and the second slot hole 1101 cooperates with the first slot hole 134.

[0043] An arc-shaped recess 182 is formed on the inner wall of the pressing plate 18 and cooperates with the outer wall of the micro motor 16. The arc-shaped recess 182 is attached to the outer wall of the micro motor 16 to prevent the outer wall of the micro motor 16 from loosening.

[0044] A limiting groove 181 is formed on the inner wall of the pressing plate 18 and extends horizontally. The straight rack 113 is horizontally and movably connected in the limiting groove 181. The adjusting bolt 114 is horizontally and rotatably connected between the end inner wall of the limiting groove 181 and the adjacent side outer wall of the pressing plate 18. The arc-shaped outer wall edge of the fan-shaped driving plate 111 extends into the limiting groove 181 to prevent the fan-shaped driving plate 111 from moving up and down during rotation.

[0045] The working principle of the micro motor 16 driving the locking strip 17 to move is as follows:

[0046] In the locked state, the axis line of the two traction columns 110 is parallel to the side outer wall of the stop block 172 facing the two traction columns 110. The end of the locking strip 17 close to the rotating end 21 is always inserted into the annular locking groove 21 under the rebounding force of the reset spring 14. When the chip 4 receives and processes the unlocking instruction, it sends a power-on instruction to the battery 6. After receiving the power-on instruction, the battery 6 starts the micro motor 16 to rotate the rotating shaft by 90 degrees. The axis line of the two traction columns 110 is rotated to be perpendicular to the side outer wall of the stop block 172 facing the two traction columns 110 by means of the rotating disc 19. During rotation, the traction column 110 close to the stop block 172 forces the stop block 172 to move against the reset direction of the locking strip 17, thereby driving the end of the locking strip 17 close to the rotating end 21 to move away from the annular locking groove 21, thereby achieving the purpose of unlocking. During this process, the reset spring 14 is further compressed. When it is necessary to lock again, the rotating shaft of the driving micro motor 16 is rotated forward or reverse by 90 degrees to make the axis line of the two traction columns 110 parallel to the side outer wall of the stop block 172 facing the two traction columns 110 again. The rebounding force of the reset spring 14 pushes the locking strip 17 to move along its reset direction until the end of the locking strip 17 close to the rotating end 21 is inserted into the annular locking groove 21 again.

[0047] When the battery 6 is out of power or the lock core is malfunctioning, a matching mechanical key can be used to pass through the second slot hole 1101 on the shell 11 and the first slot hole 134 on the core body 13 in turn, and then inserted into the open slot 173 on the locking strip 17, and then the mechanical key is moved against the reset direction of the locking strip 17 to drag the locking strip 17 to move, so as to realize manual unlocking.

[0048] Working principle of the position detection unit:

[0049] When the locking strip 17 moves against its reset direction, the sector-shaped drive plate 111 in the position detection unit moves synchronously with the locking strip 17. Since the arc-shaped tooth surface 1111 on the sector-shaped drive plate 111 is in mesh with the tooth surface of the straight-line rack 113 on the pressing plate 18, the sector-shaped drive plate 111 rotates while moving, thereby driving the micro switch 15 to rotate towards the inside of the clamping concave cavity 171. When the moving contact of the micro switch 15 contacts the upper or lower edge of the opening of the clamping concave cavity 171, the moving contact of the micro switch 15 is pressed to retract and starts to slide along the upper or lower inner wall of the clamping concave cavity 171 to maintain the retracted state of the moving contact of the micro switch 15. When the moving contact of the micro switch 15 is pressed to retract, the micro switch 15 sends a signal to the chip 4. After receiving and processing, the chip 4 sends an instruction to the communication module 5. After receiving the instruction, the communication module 5 sends a wireless signal to the operation end intelligent device to indicate that the locking is completed. Similarly, when unlocking, the sector-shaped drive plate 111 rotates in the opposite direction, thereby driving the micro switch 15 to rotate synchronously. When the moving contact of the micro switch 15 moves away from the upper or lower edge of the opening of the clamping concave cavity 171, it automatically resets. At this time, the micro switch 15 sends a signal to the chip 4. The chip 4 sends a wireless signal to the operation end intelligent device through the communication module 5 to indicate that the unlocking is completed. In this way, the person using the operation end intelligent device can timely and accurately master the state of the padlock to know whether the padlock is in the locked or unlocked state.

[0050] When assembling the padlock, after the pressing plate 18 is fixed to the core body 13, although the arc-shaped tooth surface 1111 on the sector-shaped drive plate 111 is in mesh with the tooth surface of the straight-line rack 113 on the pressing plate 18, the initial position of the micro switch 15 is deviated, so manual debugging is needed. The debugging method is as follows:

[0051] A debugging method of an intelligent padlock, comprising the following steps:

[0052] S1: Start the micro motor 16 to drive the two traction columns 110 to rotate to the locking position through the rotating disc 19, thereby making one end of the locking strip 17 close to the rotating end 21 inserted into the annular locking groove 21;

[0053] S2: detecting whether the chip 4 connected with the micro switch 15 receives the signal sent by the micro switch 15;

[0054] S21: if the micro switch 15 does not send the signal, it indicates that the moving contact of the micro switch 15 does not contact the upper side or the lower side edge of the opening of the clamping cavity 171; then the adjusting screw 114 is screwed by using a tool, and the straight rack 113 is slowly moved along the limiting groove 181 according to the principle of screw connection, so that the sector driving plate 111 is rotated to change the position of the micro switch 15 until the micro switch 15 sends the signal to the chip 4;

[0055] S22: if the micro switch 15 sends the signal when the locking strip 17 just starts to move, it indicates that the moving contact of the micro switch 15 contacts the upper side or the lower side edge of the opening of the clamping cavity 171 too early; at this time, the adjusting screw 114 needs to be unscrewed by using a tool to change the position of the micro switch 15 in the opposite direction;

[0056] S3: repeating steps S21 and S22, and then continuing to screw or unscrew the adjusting screw 114 to adjust the moving contact of the micro switch 15 to the appropriate position, so that the end of the locking strip 17 close to the rotating end 21 is completely away from the annular locking groove 21, and the moving contact of the micro switch 15 is just away from the upper side or the lower side edge of the opening of the clamping cavity 171.

[0057] The present application can know whether the padlock has been really opened in real time and accurately through the position detection unit, and the person with the unlocking permission can quickly master the dynamic of the padlock without communicating with the actual unlocking person who is close to the padlock after operating the intelligent device and performing the unlocking action, thereby having the locking state feedback function to significantly improve the use convenience and reliability; in addition, once the padlock fails or is damaged by the person and is in the unlocked state, the person with the unlocking permission can also first master the above situation by means of the position detection unit to monitor the locking state of the intelligent padlock at any time, thereby effectively enhancing the safety protection function.

[0058] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
