Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lock technology, specifically relating to a passive padlock with an authorized switch lock based on the switch status and an active key that can authorize the switch. Background Technology
[0002] In railway operations, for safety reasons and to prevent people from entering the track area, fences are often erected on both sides of the tracks, with protective gates on the fences. To ensure that specific personnel can open these gates, they are usually equipped with programmable padlocks. These padlocks have identification tags that can be identified by a smart key. The smart key stores the operator's information and can only identify the identification tag of each programmable padlock when the operation is performed correctly, thus ensuring the correct operation of the device. Existing smart locks, because they contain control circuits, require a power supply to the lock cylinder to power the control circuits. Since the power supply occupies a large space, the lock cylinder itself also increases in size. However, in certain applications, such as when the door is thin, a larger lock cylinder cannot be installed. Therefore, it is necessary to consider how to achieve intelligent unlocking and locking without a power supply to the lock cylinder structure.
[0003] Currently, existing smart passive padlocks on the market generally use two conventional design schemes for their on / off status detection elements, as detailed below:
[0004] Option 1 requires an electronic key. The electronic key has contactable components for power output and signal reading / output, while the passive padlock has contactable components for power input and signal input. The electronic key carries a control IC, and the passive padlock has an IC for unique identification. After the key IC issues an authorization command, the passive padlock IC must execute an unlock or lock command. The passive padlock executes the unlock or lock command based on the forward or reverse rotation of the padlock motor; forward rotation represents unlocking, and reverse rotation represents locking, or vice versa. The success of unlocking or locking is determined by the motor's forward or reverse rotation. After the motor rotates forward or reverse, a log is uploaded to the padlock IC, which then uploads it to the electronic key IC. Therefore, the judgment of a successful unlock in this method is not based on whether the padlock shank actually changes from a locked to an open state; similarly, the judgment of a successful lock is not based on whether the padlock shank actually changes from an open to a locked state.
[0005] Strictly speaking, the unlocking log uploaded by an electronic key cannot be generated solely after the electronic key IC issues an unlocking command, without considering the entire process of whether the key clutch changes to an unlockable state and whether the operator turns the key to change the padlock beam from closed to open. The unlocking log should be obtained and reported only after the entire process is completed: reading the padlock ID, confirming the padlock beam is closed, authorizing the recognized padlock ID with the key IC, changing the key clutch to the unlocking state, and the operator turning the key to forcibly change the padlock beam from closed to unlocked. Only after this process is completed can the electronic key generate the unlocking log and simultaneously upload it to the host computer via Bluetooth, Type-C data cable, 4G, or other communication methods.
[0006] Option 1 has a significant design flaw in its acquisition of unlock and lock logs. Therefore, during user operation, if the motor fails to rotate in the correct direction due to hardware issues, or if the contact time during unlocking or locking is less than the required rotation time, resulting in the motor not rotating or not rotating fully, the key will incorrectly acquire the unlock and lock logs. The result will inevitably be erroneous, failing to achieve the intended strict control.
[0007] Option two requires an electronic key. This electronic key must include an IC and component structure that uses a near-end signal to read the padlock's ID. The corresponding passive padlock must also have an IC and component structure to uniquely identify itself. The electronic key must have a structure that allows for changing the clutch state via IC commands, enabling future actions to open or close the padlock. When the operator turns the key, the passive padlock must have a structure that coordinates with the key's clutch operation to open or close the padlock's locking shank. The electronic key must have a charged battery. Based on the battery level and the padlock's ID reading IC and component structure, it reads the passive padlock's unique identification and feeds the passive padlock ID back to the key IC. The key IC then authorizes changes to the clutch state of the passive padlock. When the clutch state changes to the unlockable position, the operator can turn the key to open the passive padlock's unlocking mechanism and then open the lock beam. When the clutch state changes to the de-lockable position, the operator can manually insert the lock beam back into the locked position and simultaneously turn the key to close the passive padlock's locking mechanism. Therefore, the acquisition and uploading of the unlocking log in this scheme depends on whether the electronic key sends an unlocking command to the key's clutch. Whether the clutch automatically changes to the unlockable state and whether the operator actually turns the key to open the padlock's unlocking mechanism are unknown. The key also cannot obtain the actual unlocking or de-locking status of the padlock after manual operation through sensors such as Hall effect sensors. Therefore, this unlocking or de-locking log is inaccurate. The de-locking log is completely impossible to obtain and upload, existing in a non-existent design state.
[0008] Strictly speaking, the locking log uploaded by the electronic key should not be missing, nor should it be generated solely upon the electronic key IC issuing the locking command, without considering the entire process of whether the key clutch has changed to a locking state and whether the operator has turned the key to change the padlock beam from open to closed. The locking log should go through the complete process of reading the padlock ID, confirming the padlock beam is in the open state, authorizing the identified padlock ID with the key IC, changing the key clutch to the locking state, and the operator turning the key to forcibly change the padlock beam from the unlocked to the locked state. Only after this process is completed can the electronic key generate the locking log and simultaneously upload it to the host computer via Bluetooth, data cable, 4G, or other communication methods.
[0009] Option 2 suffers from a significant design flaw in its unlocking log acquisition mechanism and lacks a locking log. Therefore, during user operation, if the key is not turned to the lock's operating position due to human error, resulting in insufficient key travel and the lock not actually opening, the key will incorrectly acquire the unlocking log, leading to an erroneous result. Furthermore, the lack of a locking log prevents the tracking of whether the lock has changed from open to closed, further compromising security. This design flaw prevents administrators from verifying whether the lock is properly closed and whether the site is safe; it also hinders remote inspection via a host computer that allows viewing the locking log. These shortcomings are unacceptable to customers.
[0010] Therefore, this solution provides a passive padlock with an authorized switch lock based on the switch status and an active key that can authorize the switch, in order to solve the above-mentioned technical problems. Utility Model Content
[0011] The purpose of this invention is to provide a passive padlock with an authorized switch lock based on the switch status and an active key that can authorize the switch, solving the technical problem of how to obtain both the unlocking and closing logs simultaneously and avoiding the key from mistakenly obtaining the unlocking and closing logs.
[0012] A passive padlock based on switch status authorization includes a lock body and a lock beam. The fixed end of the lock beam is fixed in the lock body. The lock body is provided with a locking structure, a driving structure and a passive controller. The locking structure is separately connected to one side of the lock beam, and the driving structure is drivenly connected to the locking structure.
[0013] The locking structure includes a horizontal pin that is movably engaged with the locking beam at one end, and a transverse spring that is connected to the other end of the horizontal pin at one end.
[0014] The drive structure includes a passive lock cylinder assembly, a lock sleeve fitted on the outside of the passive lock cylinder assembly, and an electronic tag snapped onto the bottom of the lock sleeve. The passive controller is fixed on the passive lock cylinder assembly and includes a Hall sensor.
[0015] The outer end of the horizontal pin is provided with a slot to form a protrusion, which is movably embedded in the opening slot opened on the outer side of one end of the lock beam.
[0016] The side of the horizontal pin is provided with a second slot, and the top of the passive lock cylinder assembly is eccentrically rotatably connected in the second slot.
[0017] The passive lock cylinder assembly includes a rotating sleeve, an eccentric part fixed to the top of the rotating sleeve, a lock cylinder fixedly connected to the bottom of the rotating sleeve, and a lock ball seat bolted to the lock cylinder. The lock ball seat is sleeved on the outside of the lock cylinder, and the eccentric part is eccentrically embedded in the second slot.
[0018] The rotating sleeve, the lock cylinder, and the lock ball seat are embedded inside the lock sleeve.
[0019] The passive controller also includes a communication module and an electronic tag. The electronic tag sends identification information to the communication module (Type-C, Bluetooth, 4G communication, and other communication modules) through the motherboard. After the Hall sensor obtains battery power from the passive key through the power supply contact, it transmits the open or closed status of the padlock to the motherboard through the signal contact, thereby enabling the motherboard to control the operation of the drive structure.
[0020] The reader on the active key reads the electronic tag on the passive padlock to confirm whether the padlock ID is in the key command unlock or lock list, which is the first prerequisite; then it reads the open or closed status of the Hall sensor on the passive padlock, which is the second prerequisite.
[0021] An opening is provided on one side of the lock body, the horizontal pin is slidably disposed in the opening, and a sealing pin is provided at the outer end of the opening.
[0022] The bottom of the lock sleeve and the electronic tag are provided with dust covers, which are located at the bottom of the lock body.
[0023] An authorizing active key includes a housing, a main board and a battery disposed inside the housing, and a clutch structure disposed inside the housing. The clutch structure is connected to a key head. A pin socket is disposed on the inner side of the key head. A power supply contact and a Hall effect switch signal reading contact are disposed on the outer end of the pin socket. The power supply contact and the Hall effect switch signal reading contact are connected to the main board.
[0024] The clutch structure includes an electromagnet, a clutch fork fixedly connected to the electromagnet, a fixed sleeve sleeved on the outside of the clutch fork, a clutch sleeve separately connected to the clutch fork, and a reading head sleeved on the outside of the clutch sleeve. The key head is fixedly connected to the inside of the clutch sleeve.
[0025] The reader reads the ID of the electronic tag using low-frequency RFID technology and sends it to the key's mainboard. The key then confirms whether the ID of the electronic tag is in the list of commands to unlock or lock.
[0026] The housing includes a middle frame, a rear cover and a front cover respectively fixed on both sides of the middle frame, forming a receiving cavity.
[0027] The housing is equipped with a power button, which is connected to the audio-visual module.
[0028] The communication module includes Bluetooth communication, Type-C, and 4G communication, but is not limited to these three communication methods.
[0029] The beneficial effects of this utility model are as follows:
[0030] (1) The unlocking and locking operations of the passive padlock in this solution provide corresponding unlocking and locking logs; the ID of the passive padlock, combined with the Hall sensor embedded in the passive padlock, truly uploads the changes in the padlock status to the key IC, and uploads the unlocking and locking logs in real time after the operation ends, with particular emphasis on the fact that the locking logs cannot be missing.
[0031] (2) The acquisition of the unlocking and locking operation logs of the passive padlock in this solution is real; the log acquisition takes into account the entire operation process and goes through the complete process of reading the padlock ID with the key, reading the lock beam status on the passive padlock as open or closed, the key IC authorizing the identification of the padlock ID, the key clutch changing to the unlocking or locking state, and the operator turning the key to force the padlock beam to change from the unlocking state to the locking state or vice versa.

[0052] Example 2
[0053] See Figure 1 and Figure 3 An authorized active key includes a housing, a main board 23 disposed inside the housing, and a battery 14. The housing also has a clutch structure connected to a key head 17. The key head 17 has a pin socket 16 on its inner side, and an electrical contact is provided on the outer end of the pin socket 16.

[0056] The housing is equipped with a power button 21, which is connected to the sound and light module. Both the power button 21 and the sound and light module are existing technologies and will not be described in detail here. When the power button 21 is turned on, the sound and light module will work, emitting a sound and lighting up the light, indicating that the start-up is successful.
[0057] The communication module includes Bluetooth, Type-C, and 4G communication, but is not limited to these three communication methods.
[0058] The specific working process of this utility model:
[0059] This utility model of a passive padlock uses a main board 23 and a battery 14. The pin socket 16 has electrical contacts. The battery 14 can form a circuit with the passive padlock's circuitry through these contacts, thus providing power to the passive padlock. The main board 23 can control the passive padlock's circuitry to lock and unlock via these contacts. Specific operation is as follows:
[0060] When the smart lock of this utility model is unlocked, the passive key is activated, the electronic tag 8 receives the operation information sent by the communication module, and determines whether the current operation information matches the RFID electronic tag code of the passive padlock. Then, the main board 23 controls the electromagnet 24 to work, and the electromagnet 24 attracts or repels the clutch fork 25, causing it to move back and forth.
[0061] The electrical contacts on the pin socket 16 of the active key 12 are in contact with the conductive probes on the Hall sensor 61 (there are three conductive probes, two of which are positive and negative, and the other is connected to the Hall sensor 61). The battery 14 provides power to the Hall sensor 61 through the electrical contacts, thus conducting the circuit. The outer end of the key head 17 is connected to the lock cylinder 6 for manually driving the lock cylinder 6 to rotate. The reading head 19 is in contact with the electronic tag 8 for identifying the identity information of the passive padlock. At the same time, one end of the clutch sleeve 18 is engaged with the inner end of the lock sleeve 7, and the lock sleeve 7 plays the role of fixing and limiting the clutch sleeve 18.
[0062] When Hall sensor 61 is turned on, it sends verification information to main board 23. After verifying the verification information, main board 23 controls electromagnet 24 to engage clutch fork 25 and separate one end of clutch sleeve 18. At this time, people can turn active key 12 to 90°. At this time, key head 17 actively drives passive lock cylinder assembly to rotate 90° under external force, while clutch sleeve 18 is limited on lock sleeve 7, so that clutch sleeve 18 and key head 17 rotate relative to each other (in essence, clutch sleeve 18 is stationary and key head 17 rotates). Rotating sleeve 4 is eccentrically connected to lock sleeve 5. Therefore, the rotation of rotating sleeve 4 can make horizontal pin 10 move horizontally, so that one end of horizontal pin 10 is disengaged from the slot on lock beam 1, thereby opening lock beam 1 and moving it from lock body 3, and unlocking is successful.
[0063] The two conditions for unlocking are: first, the reader 19 contacts the electronic tag 8 to identify whether the ID information is on the list of commands to unlock or lock from the key motherboard; second, the motherboard 23 actively reads the open or closed state of the padlock's Hall sensor 61. The motherboard 23 combines these two conditions to decide whether to control the clutch fork 25 to disengage from the clutch sleeve 18.
[0064] When both conditions are met, the main board 23 controls the clutch fork 25 to separate from the clutch sleeve 18, allowing people to unlock the lock. After unlocking, the magnet 2 on the lock body 3, driven by the movable end of the lock beam 1, separates from the Hall sensor 61. The Hall sensor 61 senses the separation signal and sends it to the main board 23. The main board 23 records the unlocking log and sends the log record to the communication module, providing feedback on whether the passive padlock has gone from closed to fully open. After people complete the unlocking operation and create the unlocking log, the main board 23 controls the clutch fork 25 to engage with the limit port of the clutch sleeve 18, preventing people from unlocking the lock and forcing them to wait for the locking operation.
[0065] When locking is required, the horizontal pin 10 cannot rotate because the fixed end of the lock beam 1 blocks the horizontal pin 10. At this time, the movable end of the lock beam 1 needs to be pressed back into the lock body 3, so that the movable end of the lock beam 1 drives the magnet 2 to approach the Hall sensor 61. Then, the active key 12 is turned to 90°, so that the horizontal pin 10 engages with the slot on the lock beam 1, thus locking. At this time, the Hall sensor 61 senses the closing signal and sends it to the main board 23 to record the locking log. The main board 23 then sends the locked log record to the communication module.
[0066] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
