[0030] Figure 1 This is a cross-sectional schematic diagram of an embodiment of the electronically coded lock system of the present invention during conventional unlocking using a computer key. Figure 2 This is a cross-sectional schematic diagram of an embodiment of the electronic coded lock system of the present invention when using a backup computer key for unlocking. The electronic coded lock system includes an electronic coded lock and a computer key that is compatible with the electronic coded lock.

[0031] Figure 3 This is a cross-sectional schematic diagram of an electronically coded lock in one embodiment of the electronically coded lock system of the present invention. The electronically coded lock 100 includes a control circuit 130, a relay, a micro switch 140, and an interface module 150. The control circuit 130 includes a microcontroller, an electrical control circuit, and an emergency control circuit that are electrically connected to each other. The relay is connected to the control circuit 130 and enables the electrical control circuit to conduct in order to unlock the electrical control circuit. The micro switch 140 is connected to the control circuit 130 and enables the emergency control circuit to conduct in order to unlock the emergency control circuit.

[0032] The interface module 150 includes a base 151 and a lock cylinder assembly 152. The lock cylinder assembly 152 includes a lock cylinder 1521, a wireless power supply module 1522, a first magnet 1523, a rotating lug 1525, a locking pin 1526, and a second magnet 1527. The lock cylinder 1521 is rotatably mounted on the base 151 and has an unlocking hole 15211, a locking pin 1526 mounting hole, and a mounting cavity located at the front end of the lock cylinder 1521. The wireless power supply module 1522 and the first magnet 1523 are disposed within the mounting cavity. The rotating lug 1525 is located at the rear end of the lock cylinder 1521, and its rotation triggers the micro switch 140. The locking pin 1526 is movably disposed in the mounting hole of the locking pin 1526. The base 151 has a locking hole 1513. The locking pin 1526 extends into the locking hole 1513 to be in a locked state. The locking pin 1526 retracts into the mounting hole of the locking pin 1526 to be in an unlocked state. The second magnet 1527 is fixedly disposed on the locking pin 1526 and is located at the end of the locking pin 1526 near the unlocking hole 15211.

[0033] The computer key 200 includes a power supply coil 210, a Hall element 220, a first unlocking lever 230, a third magnet 240, and an authorization mechanism 250. When the computer key 200 is inserted into the unlocking hole 15211, the power supply coil 210 is positioned directly opposite the wireless power supply module 1522. The power supply coil 210 can wirelessly communicate with the wireless power supply module 1522 and provide power to it. When the computer key 200 is inserted into the unlocking hole 15211, the Hall element 220 is positioned directly opposite the first magnet 1523. When the first magnet 1523 approaches the Hall element 220, the Hall element 220 is activated, thereby putting the power supply coil 210 into operation. The first unlocking lever 230 is shaped to fit the unlocking hole 15211. The third magnet 240 is movably disposed within the first unlocking lever 230. In the authorized state, the third magnet 240 moves to attract the second magnet 1527, causing the locking pin 1526 to move to the unlocked state. In the authorized state, the third magnet 240 does not attract the second magnet 1527. The authorization mechanism 250 can drive the third magnet 240 to move between the authorized and unauthorized states.

[0034] The electronic coded lock system according to embodiments of the present invention can solve the problems of the existing electronic coded lock 100 being difficult to maintain normal operation for a long time and being unreliable. The wireless power supply module 1522 is integrated on the lock cylinder 1521. When the computer key 200 is turned, the wireless power supply module 1522 moves synchronously with the computer key 200, which can always maintain the stability and reliability of wireless power supply and wireless communication, while having high power supply efficiency and improving the operational reliability of controlling the electronic coded lock 100 to switch states.

[0035] In some embodiments, the coded lock 100 further includes a front housing 110 and a rear cover 120. The front housing 110 has a mounting cavity; the control circuit 130 is fixedly mounted in the mounting cavity of the front housing 110. A base 151 is fixedly disposed on the front housing 110 and connected to the front housing 110 via a snap-fit ​​1511. The rear cover 120 covers the rear end of the front housing 110 to form a closed cavity together with the front housing 110.

[0036] In some embodiments, the lock cylinder assembly 152 is rotatably mounted on the base 151, and the lock cylinder assembly 152 has an unlocked position and a locked position. When the lock cylinder assembly 152 is in the locked position, the micro switch 140 is in an untriggered state, and the emergency control circuit is disconnected; when the lock cylinder assembly 152 is in the unlocked position, the micro switch 140 is triggered by the lock cylinder assembly 152, and the emergency control circuit is connected.

[0037] In some embodiments, the wireless power supply module 1522 is disposed within the mounting cavity of the lock cylinder 1521 and can wirelessly communicate with the computer key 200. The computer key 200 can be coupled to the wireless power supply module 1522 to supply power to the control circuit 130. The first magnet 1523 is disposed within the mounting cavity of the lock cylinder 1521 and is used to cooperate with the Hall element 220 of the computer key 200 when the computer key 200 is brought near, thereby activating the computer key 200 to provide wireless power.

[0038] In some embodiments, the lock cylinder assembly 152 further includes a housing 1524 that covers the mounting cavity to enclose the wireless power supply module 1522 and the first magnet 1523 within the mounting cavity.

[0039] In some embodiments, a locking pin 1526 is movably disposed within a locking pin 1526 mounting hole, and a locking hole 1513 is provided on the base 151. When the locking pin 1526 is in the locked state, the end of the locking pin 1526 away from the unlocking hole 1521 extends into the locking hole 1513 to prevent the lock cylinder 1521 from rotating relative to the base 151. When the locking pin 1526 is in the unlocked state, the locking pin 1526 is fully retracted into the locking pin 1526 mounting hole, releasing the restriction on the lock cylinder 1521, allowing the lock cylinder 1521 to rotate relative to the base 151.

[0040] The third magnet 240 is movably disposed within the first unlocking lever 230, and the magnetic poles of the third magnet 240 are different from those of the second magnet 1527. When the computer key 200 is in the authorized state, the third magnet 240 moves to a position opposite to the second magnet 1527, and the magnetic force of the third magnet 240 is sufficient to attract the second magnet 1527 to move, so the locking pin 1526 can move to the unlocked position. When the computer key 200 is in the unauthorized state, the third magnet 240 does not move, and the distance between the third magnet 240 and the second magnet 1527 is too far to attract the second magnet 1527 to move, so the locking pin 1526 remains in the locked position.

[0041] In some embodiments, the unlocking hole 15211 is offset from the rotation center of the lock cylinder 1521, and the cross-section of the unlocking hole 15211 is an irregular structure. The first unlocking rod 230 has an irregular cross-section that matches the unlocking hole 15211.

[0042] In some embodiments, the control circuit 130 further includes a wireless radio frequency circuit and a wireless power supply receiving circuit. The wireless radio frequency circuit is used for wireless communication between the electronically coded lock 100 and the computer key 200, and the wireless power supply receiving circuit is used to receive power from the computer key 200 and rectify it. A through hole is provided on the lock cylinder 1521, penetrating the front and back of the lock cylinder 1521 and connecting the mounting cavity. The wireless power supply module 1522 is electrically connected to the control circuit 130 through a wire disposed in the through hole.

[0043] Figure 4 This is a schematic diagram showing the position of the rotating lug in the locked state in one embodiment of the electronic coded lock system of the present invention. Figure 5 This is a schematic diagram of the rotating ear position in a standby unlocking state according to an embodiment of the electronic coded lock system of the present invention. In some embodiments, the rotating ear 1525 has a protrusion 15251. When the rotating ear 1525 is rotated to the unlocking state, the protrusion 15251 abuts against the spring 141 of the micro switch 140 to trigger the micro switch 140 to conduct the emergency control circuit.

[0044] In some embodiments, a limiting groove 15252 is provided on the rotating ear 1525, and a stop boss 1512 is provided on the base 151. The stop boss 1512 can rotate within the limiting groove 15252 by a preset angle to limit the movement range of the rotating ear 1525. In this embodiment, the preset angle is 0-90 degrees as an example for explanation.

[0045] In some embodiments, the lock cylinder 1521 has a mounting hole for a positioning bead 1529, which communicates with the unlocking hole 15211. The lock cylinder assembly 152 also includes a locking pin spring 1528 and a positioning bead 1529. The locking pin spring 1528 is disposed in the mounting hole for a locking pin 1526, with one end abutting against the locking pin 1526 and the other end abutting against the lock cylinder 1521. The locking pin spring 1528 provides an elastic force for the locking pin 1526 to extend into the locking hole 1513. The positioning bead 1529 is retractably disposed in the mounting hole for a positioning bead 1529, with one end extending into the unlocking hole 15211. The retraction and extension of the positioning bead 1529 can position the computer key 200, preventing the computer key 200 from falling out of the unlocking hole 15211.

[0046] In some embodiments, the electronic coded lock system also includes an emergency unlocking key 300 associated with the electronic coded lock 100.

[0047] Figure 6 This is a cross-sectional schematic diagram of an embodiment of the electronically coded lock system of the present invention when using the emergency unlocking key. Figure 7 This is a perspective view of an embodiment of the electronic coded lock system of the present invention when using an emergency unlocking key. The emergency unlocking key 300 includes a second unlocking rod 310 and a fourth magnet 320. The second unlocking rod 310 is adapted to the shape of the unlocking hole 15211. The second unlocking rod 310 may have an irregular cross-section that matches the unlocking hole 15211. The fourth magnet 320 is fixedly disposed on the second unlocking rod 310. When the computer key 200 is inserted into the unlocking hole 15211, the fourth magnet 320 attracts the second magnet 1527, causing the locking pin 1526 to switch from the locked state to the unlocked state.

[0048] The following will describe the standard electrical unlocking process of an electronically coded lock system:

[0049] The operator uses the computer key 200 to fully insert the first unlocking lever 230 into the unlocking hole 15211. The Hall element 220 approaches the first magnet 1523 and is activated by the first magnet 1523, thus putting the power supply coil 210 into operation. The power supply coil 210 is positioned opposite the wireless power supply module 1522 and is coupled to the wireless power supply module 1522, providing power to the wireless power supply module 1522 and communicating wirelessly with it. The computer key 200 identifies the identity of the electronic code lock 100. After successful identity verification, the microcontroller controls the relay to switch from the open state to the closed state, thus activating the electrical control circuit of the electronic code lock 100 and realizing the unlocking electrical control circuit.

[0050] It should be noted that the locking pin 1526 is always partially inserted into the first locking hole 1513 under the action of the locking pin spring 1528. The locking pin 1526 is locked between the lock cylinder 1521 and the base 151. The lock cylinder 1521 cannot rotate and remains in the locked position. At this time, the lock cylinder assembly 152 is in the locked state. Moreover, due to the role of the positioning bead 1529, the wireless communication and wireless power supply process can be guaranteed to be uninterrupted.

[0051] The following will describe the backup electrical unlocking process for the electronic coded lock system:

[0052] When the relay fails or is underpowered for some reason, the computer key 200 receives a status message indicating that the relay state switching of the coded lock 100 has failed. The computer key 200 then controls the authorization mechanism 250 to switch from an unauthorized state to an authorized state. The third magnet 240 moves to a position opposite to the second magnet 1527. The magnetic force of the third magnet 240 is sufficient to attract the second magnet 1527 to move, and the locking pin 1526 moves to the unlocking position. The operator then rotates the computer key 200 as instructed by the computer key 200. The rotating lug 1525 rotates, causing the micro switch 140 to switch from an open state to a closed state, thus activating the emergency control circuit of the coded lock 100 and enabling the unlocking of the emergency control circuit. Upon receiving a status message indicating that the micro switch 140 of the coded lock 100 has successfully switched states, the computer key 200 displays a message indicating successful unlocking.

[0053] The following will explain the emergency unlocking process of the electronic coded lock system:

[0054] When both the electrical unlocking procedure and the backup unlocking procedure fail, electrical unlocking is not possible, and an emergency unlocking is required. The operator uses the emergency unlocking key 300 to fully insert the second unlocking rod 310 into the unlocking hole 15211. The second magnet 1527 approaches the fourth magnet 320 and is positioned opposite to it. The second magnet 1527 is attracted by the fourth magnet 320, causing the locking pin 1526 to switch from the locked position to the unlocked position. At this time, the lock cylinder 1521 can rotate relative to the base 151. The operator rotates the emergency unlocking key 300. When the stop boss 1512 moves to the other end of the limit groove 15252, the lock cylinder 1521 stops rotating, causing the rotating ear 1525 to move from the locked position to the unlocked position. The protrusion 15251 abuts against the spring 141 of the micro switch 140, switching the micro switch 140 from the off state to the on state.

[0055] The embodiments of the present invention also provide control methods for various electronic coded lock systems, which can be used in electronic coded lock systems according to any of the foregoing embodiments.

[0056] In one embodiment, the control method for the electronically coded lock system includes the following steps:

[0057] When the computer key 200 is inserted into the unlocking hole 15211, the first magnet 1523 activates the Hall element 220.

[0058] The power supply coil 210 of the computer key 200 supplies power to the wireless power supply module 1522.

[0059] The power supply coil 210 communicates wirelessly with the wireless power supply module 1522 and verifies the identity of the coded lock 100.

[0060] If authentication is successful, the microcontroller controls the relay to switch from the open state to the closed state.

[0061] The microcontroller of the electronic code lock 100 feeds back the first on / off state of the electrical control circuit to the computer key 200.
