Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this utility model.
[0035] To address the problems of existing physical key management systems, such as the inability to assign permissions and remotely manage keys, the inability to record the duration of key use and the user, the need for users to remember the location of the key on the lock, the cumbersome process, and the tendency to make mistakes when returning keys, an intelligent physical key management device is proposed.
[0036] The following will be provided Figures 1 to 10 This paper provides a detailed description of the unlocking process for an intelligent physical key management device.
[0037] Please see Figure 1 Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, Figure 1 This is a three-dimensional structural diagram of the smart physical key management device pendant 2 and lock dock 12 as described in this embodiment of the utility model; Figure 2 This is a schematic diagram showing the connection relationship between the smart physical key management device pendant and the pull ring according to an embodiment of this utility model; Figure 3 This is a three-dimensional structural diagram of the pull ring locking state of an intelligent physical key management device according to an embodiment of this utility model; Figure 4 This is a cross-sectional view of the pull ring locking state of an intelligent physical key management device according to an embodiment of this utility model; Figure 5 This is a three-dimensional structural diagram of the pull ring in the open state of an intelligent physical key management device according to an embodiment of this utility model.
[0038] A smart physical key management device, comprising:
[0039] The lock dock 1 is provided with a receiving hole 11 and a button 12, wherein the button 12 is located beside the receiving hole 11;
[0040] The pendant 2 is detachably installed in the receiving hole 11, and the number of each pendant 2 corresponds to the number of the lock dock 1. The outer end of the pendant 2 is outside the receiving hole 11, and mounting holes 21 are provided on both sides of the outer end. A PCBA control board 27 is provided inside the pendant 2. The PCBA control board 27 is electrically connected to the button 12. Each pendant 2 has a unique ID and can be inserted into any lock dock 1.
[0041] Pull ring 3 is provided with a notch X. The key passes through the notch X and is hung on the pull ring. The pull ring 3 can be rotatably inserted into the mounting hole 21 of the pendant 2 through the notch X. The button 12 can change the pendant 2 from the open state to the locked state, so that the pull ring 3 cannot be rotated and the key on the pull ring 3 cannot be removed.
[0042] Specifically, the lock 1 and the pendant 2 form the most basic physical key management unit. In the unlocked state, the pull ring 3 can be exposed by rotating the pendant 2, and the key is installed on the pull ring 3 through the notch X. Pressing the button 12 on the lock dock 1 changes the pendant 2 from the open state to the locked state, so that the pull ring 3 cannot be rotated and the key cannot be removed. In the open state of the pendant 2, the contact pin 210 receives the signal from the lock dock 1, the PCBA control board 27 processes the signal, executes the command with operation authority, causes the first motor 23 to rotate, drives the first eccentric wheel 24 to rotate to a predetermined angle, so that the first eccentric wheel 24 loses its limit on the limit member 25. Then, by manual operation, it moves backward to compress the return spring 26, so that the pull ring 3 can rotate and the key cannot be removed, thus realizing the binding of the key and the pull ring 3.
[0043] After the key is inserted, under the action of the limit member 25 and the return spring 26, the pull ring 3 is rotated to bind the key to the pendant 2. When the pendant 2 is inserted into the lock dock 1, it touches the contact pin 210. The contact pin 210 receives the signal, and the motor drives the first eccentric wheel 24 to rotate at a certain angle, so that the limit member 25 cannot be moved away by compressing the limit member 25 and the return spring 26, thus locking the key to the pendant 2.
[0044] When the user enters the password, the lock seat 24 controls the PCBA control board 27 to start the motor. The first motor 23 drives the first eccentric wheel 24 to move the rack 28 to the left, thereby causing the locking pin 13 to disengage from the first groove 28. Then, the spring of the contact pin 210 pops the hanging piece 2 to the position of the bulletproof stop 110, at which point the hanging piece 2 can be manually pulled out.
[0045] Beneficial effects:
[0046] I. This system provides a feasible solution for the intelligent management of physical keys, thereby solving the problem of the traditional manual management model that requires manual intervention and freeing up human resources;
[0047] 2. The combination of miniature pendant 2 and passive pendant 2 allows pendant 2 to be conveniently categorized and managed with physical keys during use. Pendant 2 has a certain degree of strength and is not easily damaged. Pendant 2 is passive and will not work before being inserted into lock dock 1, thus avoiding hidden risks such as external interference.
[0048] Third, the lock dock 1 is designed as a docking station for the pendant 2, which can record the usage time of the physical key and the user's identity information, thus solving the problem of physical key leakage. If the pendant 2 in a certain position is a physical key used to open a specific door, once it is recorded, there will be security issues.
[0049] Please see Figure 2 and Figure 3 In one embodiment, the hanging component 2 further includes a first outer shell 22, a first motor 23, a first eccentric wheel 24, a limiting member 25, and a return spring 26. The PCBA control board 27 is connected to the first motor 23, the first eccentric wheel 24 is connected to the output end of the first motor 23, the first eccentric wheel 24 and the return spring 26 are detachably snapped together, and the return spring 26 is located behind the limiting member 25 and is elastically connected to the limiting member 25.
[0050] Specifically, under the action of the limit member 25 and the return spring 26, the pull ring 3 is rotated to bind the key to the pendant 2; when the pendant 2 is inserted into the lock dock 1, it touches the contact pin 210. The contact pin 210 receives a signal, and the motor drives the first eccentric wheel 24 to rotate at a certain angle, so that the limit member 25 cannot be moved away by compressing the limit member 25 and the return spring 26, thus locking the key to the pendant 2.
[0051] In one embodiment, the return spring 26 is used to push the limiting member 25 into the notch X of the pull ring 3 along the outer end direction of the hanging member 2.
[0052] Specifically, the pull ring 3 can be rotated in the mounting hole 21 so that the notch X is turned out of the mounting hole 21. The return spring 26 pushes the limiting member 25 towards the outer end of the hanging member 2 so that the limiting member 25 is engaged in the notch X of the pull ring 3.
[0053] In one embodiment, the first eccentric wheel 24 is preset with a first rotation angle and a second rotation angle corresponding to the two states of engagement and disengagement of the limiting member 25, and the two states of engagement and disengagement of the limiting member 25 correspond to leaving and entering the notch X of the pull ring 3.
[0054] Specifically, the implementation of the open state of widget 2 is as follows: Figure 4 As shown, the contact pin 210 receives a signal from the lock dock 12. The PCBA control board 27 processes the signal and executes the authorized operation command, causing the first motor 23 to rotate and drive the first eccentric wheel 24 to rotate to a predetermined angle. Since the first eccentric wheel 24 is no longer restricting the limit member 25, it can be manually operated to move backward to compress the reset spring 26, so that the pull ring 3 can rotate. This allows authorized operators (such as operators using the administrator password) to attach a physical key to the pendant 2.
[0055] When the key is attached to the pendant 2, under the action of the return spring 26, the pull ring 3 is rotated. The limiting member 25 will restrict the rotation of the pull ring 3. Figure 1 Figure 2 As shown, the physical key is now physically bound to the pendant 2. Also, when the pendant 2 is inserted into the lock dock 12, as... Figure 5 As shown, when the stylus 210 receives a signal, the first motor 23 rotates, causing the first eccentric wheel 24 to rotate to a certain angle, so that the limiting member 25 cannot be moved away by the compression reset spring 26, thus locking the physical key and the pendant 2.
[0056] Please see Figure 3 and Figure 4 ,
[0057] In one embodiment, the pendant 2 further includes a stylus 210, a stylus base 211, and a base spring 212 for receiving signals from the docking station 1. The base spring 212 is disposed on the stylus 210, and the stylus 210 is disposed on the stylus base 211.
[0058] How to implement the open state of widget 2: Figure 2 As shown, the contact pin 210 receives a signal from the lock dock 12. The PCBA control board 27 processes the signal and executes the authorized operation command, causing the first motor 23 to rotate and drive the first eccentric wheel 24 to rotate to a predetermined angle. Since the first eccentric wheel 24 is no longer limiting the limit member 25, it can be manually operated to move backward to compress the reset spring 26, so that the pull ring 3 can rotate. This enables authorized operators (such as operators using the administrator password) to attach the pendant 2 to the physical key.
[0059] When the key is attached to the pendant 2, the pull ring 3 is rotated under the action of the return spring 26. The limiting member 25 restricts the rotation of the pull ring 3, thus physically binding the key to the pendant 2. Also, when the pendant 2 is inserted into the lock dock 12, as... Figure 4 As shown, when the stylus 210 receives a signal, the first motor 23 rotates, causing the first eccentric wheel 24 to rotate to a certain angle, so that the limiting member 25 cannot be moved away by the compression reset spring 26, thus locking the physical key and the pendant 2.
[0060] Please see Figure 6 , Figure 6 This is a cross-sectional view of the pull ring in the open state of an intelligent physical key management device according to an embodiment of this utility model.
[0061] In one embodiment, the pendant 2 is further provided with a first groove 28, and the lock dock 1 further includes a locking pin 13 and a locking pin spring 24. The locking pin spring 24 is disposed on the locking pin 13, and the locking pin 13 is movably inserted into the first groove 28.
[0062] Specifically, when the pendant 2 is attached to the physical key, the rotation of the limiting member 25, under the action of the return spring 26, restricts the rotation of the pull ring 3, thus physically binding the physical key to the pendant 2. Also, when the pendant 2 is inserted into the lock dock 12, the contact pin 210 receives a signal, causing the first motor 23 to rotate, driving the first eccentric wheel 24 to a certain angle, preventing the limiting member 25 from being moved away by compressing the returning spring 26. This achieves locking between the physical key and the pendant 2.
[0063] Please see Figure 5 and Figure 6 , Figure 5 This is a three-dimensional structural diagram of the pull ring in the open state of an intelligent physical key management device according to an embodiment of this utility model;
[0064] Figure 6 This is a cross-sectional view of the pull ring in the open state of an intelligent physical key management device according to an embodiment of this utility model.
[0065] In one embodiment, the lock dock 12 further includes a lock seat 25, a second motor 16, a second eccentric wheel 17, and a rack 28. The second motor 16 is disposed on the lock seat 25, the second eccentric wheel 17 is disposed on the second motor 16, and the rack 28 is disposed on the second eccentric wheel 17. The rack 28 acts on the locking pin 13.
[0066] Specifically, when the contact pin 210 receives a signal from the lock dock 12, the PCBA control board 27 processes the signal and executes an authorized operation command, causing the first motor 23 to rotate. This causes the first eccentric wheel 24 to rotate to a predetermined angle. Since the limiting member 25 is no longer restricted by the first eccentric wheel 24, it can be manually moved backward to compress the return spring 26, allowing the pull ring 3 to rotate. This enables authorized operators (such as those using an administrator password) to attach the pendant 2 to a physical key.
[0067] Please see Figure 7 and Figure 8 , Figure 7This is a cross-sectional view of the lock dock of an intelligent physical key management device according to an embodiment of this utility model, showing the locking state. Figure 8 This is a diagram showing the unlocking status of a lock dock for an intelligent physical key management device as described in an embodiment of this utility model.
[0068] In one embodiment, the lock dock 1 further includes a second outer shell 29 and a bulletproof stop 110. The bulletproof stop 110 is disposed in the second outer shell 29. The hanging piece 2 is provided with a second groove 29, which is located outside the first groove. The bulletproof stop 110 can be inserted into the second groove 29.
[0069] Specifically, when the locking pin 22 disengages from the first groove 28 on the pendant 2, the pendant 2 will be ejected by the spring 211 of the contact pin seat to the position where the second groove 29 and the anti-fly stop 29 interact. At this position, the pendant 2 can be manually pulled out. The anti-fly stop 29 prevents the pendant 2 from being ejected directly after the locking pin 22 disengages from the first groove 28.
[0070] In one embodiment, the lock dock 1 further includes an emergency lever 313 disposed in the second housing 29.
[0071] Specifically, in case of abnormal situations, such as a password input failure, the emergency lever 313 can be used to open the hanging piece 2 and the pull ring 3.
[0072] Please see Figure 9 and Figure 10 , Figure 9 This is a three-dimensional structural diagram of an intelligent physical key management device according to an embodiment of the present utility model; Figure 10 This is a three-dimensional structural diagram of the opening of an intelligent physical key management device according to an embodiment of this utility model.
[0073] In one embodiment, the system further includes a cabinet 1, which includes a control panel 11; the cabinet 1 accommodates a plurality of lock docks 1.
[0074] Specifically, the wireless remote control system sends information to the bus control, and the bus control sends information to the lock docks and integrates into the bus. All lock docks will receive the information, but only the lock body with the corresponding ID will respond. Subsequently, the contact pin 210 receives the signal from the lock dock 1, the PCBA processes the signal, executes the authorized operation command, causes the first motor 23 to rotate, drives the first eccentric wheel 24 to rotate to a predetermined angle, and manually operates the limit member 25 to move backward to compress the return spring 26, so that the pull ring 3 can rotate.
[0075] Full operation process:
[0076] (1) Enter the password, lock seat control PCBA control board 27 starts the second motor 16, drives the second eccentric wheel 17, makes the rack 28 move to the left, makes the locking pin 13 disengage from the first groove 28, and the locking pin spring 24 pops the hanging piece 2 to the position of the second groove 29 and the bulletproof stop 110. Manually pull the hanging piece 2 out of the lock tungsten 2.
[0077] (2) Lock tungsten 2 sends a signal to the stylus 210, PCBA control board 27 processes the signal, executes the command with authorized operation, makes the first motor 23 rotate, drives the first eccentric wheel 24 to rotate to the predetermined angle, releases the restriction on the limit member 25, manually presses the reset spring 26, rotates the pull ring 3, and takes out the key;
[0078] (3) After inserting the key, rotate the pull ring 3 so that the notch X is aligned with the locking piece. The reset spring 26 and the limiting piece 25 spring in and lock into the notch X of the pull ring 3. The pull ring 3 cannot be rotated, and the key and the pendant 2 are bound together.
[0079] (4) Next, insert the pendant 2 into the lock tungsten 2. The contact pin 210 receives the signal. The first motor 23 drives the first eccentric wheel 24 to rotate to a preset angle, so that the limiting member 25 cannot be moved away by compressing the pull ring 3 limiting member 25 reset spring 26, so that the key and pendant 2 are locked. The second motor 16 drives the second eccentric wheel 17 to rotate to a preset angle, so that the locking pin 13 is inserted into the first groove 28.
[0080] This utility model provides a feasible solution for the intelligent management of physical keys, resolving the traditional manual management model that requires human intervention and freeing up human resources. The combination of a miniature pendant 2 and a passive pendant 2 allows for convenient categorization and management of physical keys during use. The pendant 2 possesses sufficient strength to resist damage and is passive and inactive before being inserted into the lock dock 1, eliminating potential risks such as external interference. Designing the lock dock 1 as merely a docking station for the pendant 2 solves the problem of physical key leakage. If a pendant 2 in a certain location corresponds to a physical key used to open a specific door, and this key is forcibly recorded, security issues may arise.
