[0035] To facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific examples. Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0036] In order to solve the problems in the existing technology that the physical key management system cannot assign permissions and remotely manage, cannot record the usage time and user of the physical key, requires the user to remember the lock tungsten position of the key used, the usage process is cumbersome, and it is easy to make mistakes when returning the key, a new intelligent physical key management device and system are proposed.
[0037] The following will provide Figure 1 and Figure 11 A detailed description of unlocking a new type of intelligent physical key management device is given.
[0038] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, Figure 1 This is a schematic diagram of the three-dimensional structure of a new type of intelligent physical key management device according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the three-dimensional structure of the open cover of a new type of intelligent physical key management device according to an embodiment of the present invention; Figure 3 This is a schematic diagram of the three-dimensional structure of a new type of smart physical key management device pendant 3 and lock dock 22 according to an embodiment of the present invention; Figure 6 This is a cross-sectional view of the pull ring locked state of a new type of intelligent physical key management device described in an embodiment of the present invention.
[0039] An intelligent physical key management device, comprising:
[0040] The cabinet 1 includes a control panel 11;
[0041] Lock dock 2, the cabinet 1 accommodates multiple lock docks 2, and the lock dock 2 is provided with a receiving hole 21 and a button 22;
[0042] There are multiple pendants 3, corresponding to the number of the lock docks 2. The pendants 3 are detachably arranged in the receiving hole 21. The outer end of the pendant 3 is outside the receiving hole 21, and mounting holes 31 are provided on both sides of the outer end. A PCBA control board 37 is provided in the pendant 3, and the PCBA control board 37 is electrically connected to the button 22. Each pendant 3 has a unique ID and can be inserted into any lock dock 2;
[0043] The pull ring 4 is provided with a notch, and the key is passed through the pull ring 4 through the notch. The pull ring 4 can be rotatably embedded in the mounting hole 31 of the pendant 3 through the notch. The button 22 can change the pendant 3 from an open state to a locked state, so that the pull ring 4 cannot rotate and the key passed through the pull ring 4 cannot be taken out.
[0044] Specifically, when in the unlocked state, the pull ring 4 can be rotated on the pendant 3 to expose the notch of the pull ring 4, and the key is installed on the pull ring 4 through the notch. The button 22 on the lock dock 2 is pressed to change the pendant 3 from the open state to the locked state, so that the pull ring 4 cannot be rotated and the key cannot be taken out; when the pendant 3 is in the open state, the contact pin 310 receives the signal from the lock dock 2, the PCBA control board 37 processes the signal, and executes the command with operation authority to rotate the first motor 33 and drive the first eccentric wheel 34 to rotate to a predetermined angle, so that the first eccentric wheel 34 loses the limit on the limit member 35, and then manually operates to move it backward to compress the reset spring 36, so that the pull ring 4 can be rotated and the key cannot be taken out.
[0045] After the key is inserted, the pull ring 4 is rotated under the action of the return spring 36 of the limit member 35 to bind the key to the pendant 3; when the pendant 3 is inserted into the lock dock 2, it touches the contact pin 310, the contact pin 310 receives the signal, and the motor drives the first eccentric wheel 34 to rotate a certain angle, so that the limit member 35 cannot be moved away by compressing the return spring 36 of the limit member 35, thereby locking the key and the pendant 3.
[0046] When the user enters the password, the lock seat 24 controls the PCBA control board 37 to start the motor, and the first motor 33 drives the first eccentric wheel 34 to move the rack 28 to the left, thereby disengaging the locking pin 23 from the first groove 38, and then the contact pin 310 spring pops out the pendant 3 to the position of the bulletproof fly stop 210, at which time the pendant 3 can be manually pulled out.
[0047] Beneficial effects:
[0048] 1. This system provides a feasible solution for intelligent management of physical keys, which solves the traditional management of physical keys that requires manual participation and manual management mode and liberates human resources;
[0049] 2 Micro pendant 3 + passive pendant 3, so that the pendant 3 can be conveniently classified and managed with the physical key during use. The pendant 3 has a certain strength and is not easy to be damaged. The pendant 3 is passive before being inserted into the lock dock 2 and will not work, and will not cause invisible risks such as external interference.
[0050] The lock dock 2 is designed to be just a docking station for the pendant 3, which solves the problem of physical key leakage. If the pendant 3 at a certain position is a physical key for opening a specific door, once it is rigidly recorded, there will be problems with safe use.
[0051] See also Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the connection relationship between a novel smart physical key management device pendant and the pull ring according to an embodiment of the present invention; Figure 5 It is a schematic diagram of the three-dimensional structure of the pull ring locked state of a new type of intelligent physical key management device described in an embodiment of the present invention.
[0052] In one embodiment, the hanger 3 also includes a first shell 32, a first motor 33, a first eccentric wheel 34, a limiter 35 and a return spring 36. The PCBA control board 37 is connected to the first motor 33, the first eccentric wheel 34 is connected to the output end of the first motor 33, the first eccentric wheel 34 and the return spring 36 are detachably connected, and the return spring 36 is located behind the limiter 35 and is elastically connected to the limiter 35.
[0053] Specifically, under the action of the return spring 36 of the limit member 35, the pull ring 4 is rotated to bind the key to the pendant 3; when the pendant 3 is inserted into the lock dock 2, it touches the contact pin 310, the contact pin 310 receives the signal, and the motor drives the first eccentric wheel 34 to rotate a certain angle, so that the limit member 35 cannot be moved away by compressing the return spring 36 of the limit member 35, thereby locking the key and the pendant 3.
[0054] In one embodiment, the return spring 36 is used to push the limiting member 35 into the notch of the pull ring 4 along the outer end direction of the hanging member 3 .
[0055] Specifically, the pull ring 4 can rotate in the mounting hole 31 to rotate the notch out of the mounting hole 31 , and the return spring 36 pushes the limiter 35 toward the outer end of the hanger 3 so that the limiter 35 is stuck in the notch of the pull ring 4 .
[0056] In one embodiment, the first eccentric wheel 34 is preset with a first rotation angle and a second rotation angle corresponding to the engaging and releasing states of the limiter 35 , and the engaging and releasing states of the limiter 35 correspond to leaving and entering the gap of the pull ring 4 .
[0057] Specifically, the implementation of the open state of widget 3 is as follows Figure 4 As shown, the stylus 310 receives a signal from the lock dock 22, and the PCBA control board 37 processes the signal and executes the authorized operation command to rotate the first motor 33, driving the first eccentric wheel 34 to rotate to a predetermined angle. Since the limit member 35 is no longer restricted by the first eccentric wheel 34, it can be manually operated to move backward to compress the reset spring 36, so that the pull ring 4 can rotate, thereby realizing the function of an authorized operator (such as an operator using an administrator password) to install a physical key on the pendant 3.
[0058] When the pendant 3 completes the physical key hanging, that is, under the action of the reset spring 36, the pull ring 4 is rotated, and the limiter 35 will limit the pull ring 4 from rotating. Figure 1 Figure 2 As shown, the physical key is now physically bound to the pendant 3. When the pendant 3 is inserted into the lock dock 22, as shown in FIG. Figure 5 As shown, the stylus 310 receives the signal, causing the first motor 33 to rotate and drive the first eccentric wheel 34 to rotate to a certain angle, so that the limit member 35 cannot be moved away by compressing the return spring 36, thereby locking the physical key and the pendant 3.
[0059] See also Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the three-dimensional structure of the pull ring in the locked state of the novel intelligent physical key management device according to an embodiment of the present invention; Figure 6 This is a cross-sectional view of the pull ring locked state of a new type of intelligent physical key management device described in an embodiment of the present invention.
[0060] In one embodiment, the pendant 3 further includes a stylus 310 for receiving the signal of the dock 2 , a stylus base 311 and a base spring 312 , the base spring 312 is arranged on the stylus 310 , and the stylus 310 is arranged on the stylus base 311 .
[0061] The implementation of the open state of widget 3 is as follows Figure 4As shown, the stylus 310 receives a signal from the lock dock 22, and the PCBA control board 37 processes the signal and executes the authorized operation command to rotate the first motor 33, driving the first eccentric wheel 34 to rotate to a predetermined angle. Since the limiter 35 is no longer restricted by the first eccentric wheel 34, it can be manually operated to move backward to compress the reset spring 36, so that the pull ring 4 can rotate, thereby enabling an authorized operator (such as an operator using an administrator password) to install the pendant 3 on a physical key.
[0062] When the pendant 3 is completed with the physical key hanging, that is, under the action of the reset spring 36, the pull ring 4 is rotated, and the limiter 35 will limit the rotation of the pull ring 4. At this time, the physical key is physically bound to the pendant 3. When the pendant 3 is inserted into the lock dock 22, as shown in FIG. Figure 5 As shown, the stylus 310 receives the signal, causing the first motor 33 to rotate and drive the first eccentric wheel 34 to rotate to a certain angle, so that the limit member 35 cannot be moved away by compressing the return spring 36, thereby locking the physical key and the pendant 3.
[0063] See also Figure 8 , Figure 8 This is a cross-sectional view of the pull ring in the open state of the novel intelligent physical key management device described in an embodiment of the present invention.
[0064] In one embodiment, the pendant 3 is further provided with a first groove 38 , and the locking dock 2 further includes a locking pin 23 and a locking pin spring 24 . The locking pin spring 24 is provided on the locking pin 23 , and the locking pin 23 is movably inserted into the first groove 38 .
[0065] Specifically, when the physical key is inserted into the pendant 3, the return spring 36 rotates the stopper 35, restricting the pull ring 4 from rotating. At this point, the physical key is physically bound to the pendant 3. Also, when the pendant 3 is inserted into the lock dock 22, the contact pin 310 receives a signal, causing the first motor 33 to rotate, driving the first eccentric wheel 34 to a certain angle. This prevents the stopper 35 from being dislodged by the return spring 36, thus locking the physical key to the pendant 3.
[0066] See also Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the three-dimensional structure of the pull ring in the open state of the novel intelligent physical key management device according to an embodiment of the present invention;
[0067] Figure 8 This is a cross-sectional view of the pull ring in the open state of the novel intelligent physical key management device described in an embodiment of the present invention.
[0068] In one embodiment, the lock dock 22 also includes a lock seat 25, a second motor 26, a second eccentric wheel 27 and a rack 28, the second motor 26 is arranged on the lock seat 25, the second eccentric wheel 27 is arranged on the second motor 26, the rack 28 is arranged on the second eccentric wheel 27, and the rack 28 acts on the locking needle 23.
[0069] Specifically, the stylus 310 receives a signal from the lock dock 22, which is then processed by the PCBA control board 37, executing the authorized operation command. This causes the first motor 33 to rotate, driving the first eccentric 34 to rotate to a predetermined angle. Without the restraint of the first eccentric 34, the limiter 35 can be manually moved backward, compressing the return spring 36 and allowing the pull ring 4 to rotate. This allows authorized operators (e.g., those using an administrator password) to attach the pendant 3 to a physical key.
[0070] See also Figure 9 and Figure 10 , Figure 9 This is a cross-sectional view of a new type of intelligent physical key management device in a locked state according to an embodiment of the present invention; Figure 10 This is a lock and unlock state diagram of a new type of intelligent physical key management device described in an embodiment of the present invention.
[0071] In one embodiment, the locking dock 2 also includes a second shell 29 and a bulletproof fly stop 210, the bulletproof fly stop 210 is arranged in the second shell 29, and the hanger 3 is provided with a second groove 39, the second groove is located outside the first groove, and the bulletproof fly stop 210 can be inserted into the second groove 39.
[0072] Specifically, when the locking pin 22 is disengaged from the first groove 38 of the hanger 3, the hanger 3 is ejected by the contact pin holder spring 311 to a position where the second groove 39 and the anti-flying stop 29 interact. From this position, the hanger 3 can be manually pulled out. The anti-flying stop 29 prevents the hanger 3 from directly flying after the locking pin 22 is disengaged from the first groove 38.
[0073] In one embodiment, the docking station 2 further includes an emergency lever 313 , and the emergency lever 313 is disposed in the second housing 29 .
[0074] Specifically, when an abnormal situation occurs, such as a failure in password input, the emergency lever 313 can be used to open the pendant 3 and the pull ring 4.
[0075] Figure 11 This is a structural diagram of a new type of intelligent physical key management system described in an embodiment of the present invention.
[0076] An intelligent physical key management system is applied to an intelligent physical key management device described in any of the above embodiments, including a wireless remote control system and a bus control. The bus control has multiple lock docks connected to the bus and is used to respond to control commands to the lock body with the corresponding ID.
[0077] Specifically, the wireless remote control system sends information to the bus control, and the bus control sends information to the lock dock incorporated into the bus. All lock docks will receive the information, but only the lock body with the corresponding ID will respond. Subsequently, the stylus 310 receives the signal on the lock dock 2, the PCBA processes the signal, and executes the authorized operation command to rotate the first motor 33, driving the first eccentric wheel 34 to rotate to a predetermined angle, and manually operating the limiter 35 to move it backward to compress the reset spring 36, so that the pull ring 4 can rotate.
[0078] Full operation process:
[0079] (1) Enter the password, the lock seat control PCBA control board 37 starts the second motor 26, drives the second eccentric wheel 27, moves the rack 28 to the left, and disengages the locking pin 23 from the first groove 38. The locking pin spring 24 pops the pendant 3 to the position of the second groove 39 and the bulletproof fly stop 210, and manually pulls the pendant 3 out of the lock tungsten 2;
[0080] (2) The lock tungsten 2 sends a signal to the stylus 310, and the PCBA control board 37 processes the signal and executes the command with the authorized operation, so that the first motor 33 rotates, drives the first eccentric wheel 34 to rotate to a predetermined angle, releases the restriction of the limiter 35, manually presses the reset spring 36, rotates the pull ring 4, and removes the key;
[0081] (3) After the key is inserted, the pull ring 4 is rotated so that the notch is aligned with the locking member, and the return spring 36 and the limit member 35 are ejected and locked into the notch of the pull ring 4. The pull ring 4 cannot be rotated, and the key and the pendant 3 are bound;
[0082] (4) Then, the pendant 3 is inserted into the lock tungsten 2. The contact pin 310 receives a signal, and the first motor 33 drives the first eccentric wheel 34 to rotate to a preset angle, so that the limiter 35 cannot be moved away by compressing the pull ring 4 and the return spring 36 of the limiter 35, so that the key and the pendant 3 are locked; the second motor 26 drives the second eccentric wheel 27 to rotate to a preset angle, so that the locking pin 23 is inserted into the first groove 38.
[0083] The present invention provides a feasible solution for managing physical keys through intelligent management, eliminating the traditional manual management model that requires human participation and liberating human resources. The combination of a micro pendant 3 and a passive pendant 3 allows the pendant 3 to be conveniently classified and managed with physical keys during use. The pendant 3 has a certain strength and is not easily damaged. The pendant 3 is passive and does not work before being inserted into the lock dock 2, eliminating the risk of hidden risks such as external interference. The lock dock 2 is designed to be a docking station for the pendant 3, which solves the problem of physical key leakage. If a pendant 3 in a certain position is used to open a specific door, once it is rigidly recorded, it will cause problems in safe use.
