TECHNICAL FIELD
[0001] The present application relates to the technical field of locks, in particular to a Type-C interface lock cylinder with emergency unlocking and a key. BACKGROUND
[0002] At present, the Type-C lock cylinder of the common lock on the market is generally driven by a speed reducer motor or a solenoid driving member to drive the unlocking mechanism of the lock to move, so as to realize electrical unlocking. When the unlocking mechanism of the lock is limited and causes jamming, the unlocking mechanism cannot normally operate, which will cause the unlocking failure. Or when the driving member has an electrical fault, the lock cylinder cannot normally unlock. Especially in important places such as power production, the lock cylinder cannot normally unlock, which is easy to cause adverse effects.
[0003] In related technologies, in order to make up for the fault risk of the electrical unlocking of the Type-C lock cylinder, an emergency unlocking mechanism is usually added outside the lock cylinder. This external mechanism not only increases the volume of the lock cylinder, which makes it difficult to adapt to different specifications of the lock, reduces the universality, but also usually needs to be connected mechanically by opening a hole on the lock shell, which destroys the integrity of the lock shell, makes it easy for dust and liquid to invade the inside, and affects the sealing and reliability of the core electromechanical components. SUMMARY
[0004] The present application provides a Type-C interface lock cylinder with emergency unlocking, which can improve the safety, universality and sealing of the Type-C interface lock cylinder.
[0005] The present application is realized by the following technical scheme: In a first aspect, the application provides a Type-C interface lock cylinder with emergency unlocking. The Type-C interface lock cylinder includes a lock shell, a lock cylinder assembly, a clutch block, an electrical assembly, and a magnetic pin assembly. The lock cylinder assembly, the magnetic pin assembly, and the electrical assembly are all arranged in the lock shell. The lock cylinder assembly includes a front lock cylinder, a rear lock cylinder, and a rotating shaft. The rotating shaft connects the front lock cylinder and the rear lock cylinder. The front lock cylinder is provided with a lock hole. The clutch block is sleeved on the rotating shaft. The electrical assembly includes a Type-C interface and a first driving member. The Type-C interface and the first driving member are signal connected. The Type-C interface is arranged in the front lock cylinder and extends into the lock hole. The first driving member has a first position for locking the clutch block and the lock shell and a second position for unlocking the clutch block and the lock shell. The magnetic pin assembly includes a first magnetic steel and a pin. The first magnetic steel is movably arranged in the front lock cylinder. The pin is in transmission connection with the first magnetic steel. The pin has a third position for locking the clutch block and the rotating shaft and a fourth position for unlocking the clutch block and the rotating shaft. When the electrical unlocking is performed, the pin is located at the third position. The key is inserted into the lock hole and cooperates with the Type-C interface to drive the first driving member to rotate from the first position to the second position. The key is rotated in a forward direction. The front lock cylinder and the rotating shaft drive the rear lock cylinder to rotate, thereby achieving unlocking. When the emergency unlocking is performed, the first driving member is located at the first position. The key is inserted into the lock hole. The second magnetic steel of the key drives the pin to move from the third position to the fourth position through the first magnetic steel. The key is rotated in the forward direction. The front lock cylinder and the rotating shaft drive the rear lock cylinder to rotate, thereby achieving unlocking.
[0006] The technical scheme of the embodiment of the application has the following beneficial effects. The Type-C interface and the driving member are signal connected. After the electrical key is inserted into the lock hole and cooperates with the Type-C interface, the driving member is driven to rotate to the second position. The locking of the clutch block and the rotating shaft is released. The electrical key is rotated to achieve electrical unlocking. The first magnetic steel and the pin are connected with each other. After the key is inserted into the lock hole, the second magnetic steel drives the pin to move from the third position to the fourth position through the first magnetic steel. The locking of the clutch block and the lock shell is released. The key is rotated to achieve emergency unlocking. While achieving emergency unlocking, compared with an external emergency unlocking mechanism, the Type-C interface lock cylinder has a smaller size. The safety and universality of the Type-C interface lock cylinder are improved. In addition, the lock cylinder assembly, the magnetic pin assembly, and the electrical assembly are all arranged in the lock shell. No additional hole needs to be opened on the lock cylinder assembly. The risk of dust entering the inside of the lock shell is reduced. The sealing performance of the Type-C interface lock cylinder is improved.
[0007] In some embodiments, the Type-C interface lock cylinder further includes a locking pin movably arranged in the clutch block. The first driving member is an electric motor. The electric motor has a motor shaft. The motor shaft is rotatably arranged in the rotating shaft. When the first position is reached, the motor shaft abuts against the locking pin to connect the clutch block and the lock shell. When the second position is reached, the motor shaft is separated from the locking pin to make the locking pin exit the lock shell.
[0008] The technical solution of this application embodiment, by setting a locking pin that cooperates with the clutch block and the lock housing, when in the first position, the motor shaft abuts against the locking pin, thereby locking the lock housing and the clutch block. When in the second position, the motor shaft separates from the locking pin, causing the locking pin to retract from the lock housing, thereby releasing the lock housing and the clutch block from locking, which improves the convenience of electrical unlocking.
[0009] In some embodiments, the lock housing has a first mounting groove, the clutch block has a clutch block hole, and the rotating shaft has a clearance groove. The clutch block hole communicates with the clearance groove, and the motor shaft is rotatably mounted in the clearance groove. In the first position, the motor shaft abuts against one end of the locking pin, and the other end of the locking pin extends into the first mounting groove. In the second position, one end of the locking pin extends into the clearance groove, and the other end of the locking pin extends from the first mounting groove into the clutch block hole.
[0010] The technical solution of this application embodiment, by providing a first mounting groove, a clutch block hole, and a clearance groove to cooperate with the locking pin, allows for locking of the lock housing and clutch block by means of a locking pin in the first position. In the second position, the motor shaft separates from the locking pin, causing the locking pin to retract from the lock housing. One end of the locking pin extends into the clearance groove, and the other end extends from the first mounting groove into the clutch block hole, thus releasing the lock housing from the clutch block and improving the convenience of electrical unlocking.
[0011] In some embodiments, the Type-C interface lock cylinder further includes a locking pin spring, one end of which is connected to the inner wall of the clutch block hole, and the other end of which is connected to the locking pin. The electrical components also include a torsion spring, one end of which is connected to the motor shaft, and the other end of which is connected to the front lock cylinder. During electrical unlocking, the motor shaft rotates from a first position to a second position, the torsion spring stores force, and the shaft drives the clutch block to rotate, causing one end of the locking pin to extend into the clearance groove, and the locking pin spring stores force. During electrical locking, the torsion spring drives the motor shaft to move from the second position to the first position, the key is reversed, the shaft drives the clutch block to reverse, and the locking pin spring drives one end of the locking pin to retract from the clearance groove into the clutch block hole, and drives the other end of the locking pin to extend from the clutch block hole into the first mounting groove.
[0012] The technical solution of this application embodiment realizes the reset of the motor shaft through a torsion spring and the reset of the locking pin through a locking pin spring, which helps to improve the convenience of electrical locking.
[0013] In some embodiments, the front lock cylinder has a first mounting hole, the rotating shaft has a first through hole, and the clutch block has a second mounting hole. The magnetic tumbler assembly also includes a cylindrical pin, which drivesly connects a first magnet and a tumbler, with the first magnet movably disposed in the first mounting hole. In the third position, one end of the cylindrical pin is located in the first mounting hole, and the other end of the cylindrical pin is located in the first through hole; one end of the tumbler is located in the first through hole, and the other end of the tumbler is located in the second mounting hole. In the fourth position, one end of the cylindrical pin is located in the first mounting hole, the other end of the cylindrical pin is located in the first through hole, and all the tumblers are located in the second mounting hole.
[0014] The technical solution of this application embodiment, by providing a first through hole and a second mounting hole to cooperate with the tumbler, in the third position, one end of the tumbler is located in the first through hole and the other end of the tumbler is located in the second mounting hole, thereby locking the shaft and clutch block through the tumbler. In the fourth position, all the tumblers are located in the second mounting hole, thereby releasing the lock on the shaft and clutch block through the tumbler, which improves the convenience of emergency unlocking.
[0015] In some embodiments, the magnetic pin assembly further includes a pin spring, one end of which is connected to the pin, and the other end of which is connected to the wall of the second mounting hole. In case of emergency unlocking, the key is inserted into the lock cylinder, and the pin moves from the third position to the fourth position, storing force in the pin spring. In case of locking, reversing the key rotates the rear lock cylinder via the front lock cylinder and the pivot, achieving locking, and the pin spring drives the pin to move from the fourth position to the third position.
[0016] The technical solution of this application embodiment achieves the reset of the ball by setting a ball spring, which helps to improve the convenience of locking.
[0017] In some embodiments, there are multiple magnetic pin assemblies, which are spaced apart around the axis of the front lock cylinder. At least two of the magnetic pin assemblies have first magnets with opposite magnetic properties. The key has multiple second magnets, which correspond one-to-one with the multiple first magnets, and the second magnets have the same magnetic properties as their corresponding first magnets.
[0018] The technical solution of this application embodiment reduces the risk of unlocking caused by driving multiple first magnets through magnets with the same magnetic properties by setting multiple magnetic tumbler components, and at least two magnetic tumbler components have opposite magnetic properties, which helps to improve the security of Type-C interface lock cylinder.
[0019] In some embodiments, the number of magnetic tumbler assemblies is four, with two magnetic tumbler assemblies on each side of the lock hole, and the magnetic tumbler assemblies on both sides are symmetrically arranged. Specifically, around the axis of the front lock cylinder, adjacent first magnets have opposite magnetic properties.
[0020] The technical solution of this application embodiment sets two adjacent first magnets to have opposite magnetic properties by wrapping around the axis of the front lock cylinder, so that when the key is inserted to unlock, it is not necessary to distinguish the magnetic properties of each second magnet, which helps to improve the convenience of emergency unlocking.
[0021] In some embodiments, the Type-C interface lock cylinder further includes a steel ball. The lock housing has a second mounting groove, the front lock cylinder has a second through hole, the second through hole corresponds to the second mounting groove, and the second through hole communicates with the lock cylinder. The key has a third mounting groove. In the locked state, a portion of the steel ball is located in the second mounting groove, and the other portion of the steel ball passes through the second through hole, extending into the lock cylinder from the side of the second through hole opposite to the second mounting groove. In the unlocking state, the key is inserted into the lock cylinder, and when the key is turned clockwise, a portion of the steel ball enters the second through hole from the second mounting groove, and the other portion of the steel ball extends into the third mounting groove.
[0022] The technical solution of this application embodiment, through the cooperation of the steel ball with the second mounting groove of the lock shell, the second through hole of the front lock cylinder and the key, enables the steel ball to cooperate with the front lock cylinder and the key when unlocking with the key, thereby reducing the risk of the key being pulled out.
[0023] In some embodiments, the rear lock cylinder has a fifth mounting groove at one end opposite to the front lock cylinder, one end of the rotating shaft is connected to the front lock cylinder, and the other end of the rotating shaft passes through the rear lock cylinder and is located in the fifth mounting groove. The Type-C interface lock cylinder also includes a retaining ring, which is sleeved on the other end of the rotating shaft and abuts against the bottom wall of the fifth mounting groove.
[0024] The technical solution of this application embodiment connects the rotating shaft and the rear lock cylinder with a retaining ring, which helps to improve the convenience of connecting the rotating shaft and the rear lock cylinder.
[0025] Secondly, this application provides a key for unlocking a Type-C interface lock cylinder with emergency unlocking as described in any embodiment of the first aspect. The key includes a housing, an unlocking head, a second magnet, and a second driving member. The unlocking head is connected to the housing and has a sixth mounting groove. The second magnet is movably disposed in the sixth mounting groove, and the second driving member is disposed in the housing and is drively connected to the second magnet. The second magnet has an authorized position and an unauthorized position. In the authorized position, the end of the second magnet facing away from the housing abuts against the bottom wall of the sixth mounting groove; in the unauthorized position, the end of the second magnet facing away from the housing is spaced apart from the bottom wall of the sixth mounting groove. The key has an emergency unlocking mode and an electrical unlocking mode. In emergency unlocking, the key is in emergency unlocking mode, the unlocking head is inserted into the lock hole, and the second driving member moves the second magnet from the unauthorized position to the authorized position. The second magnet, through the first magnet, moves the tumbler from the third position to the fourth position. In electrical unlocking, the key is in electrical unlocking mode, the second magnet is in the unauthorized position, the unlocking head is inserted into the lock hole and engages with the Type-C interface.
[0026] The technical solution of this application embodiment improves the convenience of unlocking by setting an emergency unlocking mode and an electrical unlocking mode on the key, while also having an emergency unlocking function to improve security.

Figure 2 A schematic diagram of a first position provided for some embodiments of this application. Figure 3 A schematic diagram showing another perspective of the first position provided for some embodiments of this application.

Figure 5 A schematic diagram of a third position provided for some embodiments of this application. Figure 6This is a schematic diagram of a fourth position provided for some embodiments of this application. In a first aspect, this application provides a Type-C interface lock cylinder 1 with emergency unlocking. The Type-C interface lock cylinder 1 includes a lock housing 10, a lock cylinder assembly 20, a clutch block 30, an electrical assembly 40, and a magnetic pin assembly 50. The lock cylinder assembly 20, the magnetic pin assembly 50, and the electrical assembly 40 are all disposed within the lock housing 10. The lock cylinder assembly 20 includes a front lock cylinder 21, a rear lock cylinder 22, and a rotating shaft 23. The rotating shaft 23 connects the front lock cylinder 21 and the rear lock cylinder 22. The front lock cylinder 21 has a lock hole 213. The clutch block 30 is sleeved on the rotating shaft 23. Electrical component 40 includes a Type-C interface 41 and a first drive member 42, which are signal-connected. The Type-C interface 41 is located in the front lock cylinder 21 and extends into the lock hole 213. The first drive member 42 has a first position for locking the clutch block 30 and the lock housing 10 and a second position for releasing the clutch block 30 and the lock housing 10 from locking. Magnetic pin assembly 50 includes a first magnet 51 and a pin 52. The first magnet 51 is movably disposed within the front lock cylinder 21, and the pin 52 is drive-connected to the first magnet 51. The pin 52 has a third position for locking the clutch block 30 and the rotating shaft 23 and a fourth position for releasing the clutch block 30 and the rotating shaft 23 from locking. During electrical unlocking, pin 52 is in the third position. Key 80 is inserted into keyhole 213 and engages with Type-C interface 41 to drive first drive component 42 from the first position to the second position. Rotating key 80 forward causes the rear lock cylinder 22 to rotate via front lock cylinder 21 and pivot 23, thus unlocking the device. During emergency unlocking, first drive component 42 is in the first position. Key 80 is inserted into keyhole 213. Second magnet 85 of key 80, via first magnet 51, moves pin 52 from the third position to the fourth position. Rotating key 80 forward causes the rear lock cylinder 22 to rotate via front lock cylinder 21 and pivot 23, thus unlocking the device.
[0038] In some embodiments, the lock cylinder assembly 20 includes a front lock cylinder 21, a rear lock cylinder 22, and a pivot 23. The front lock cylinder 21 can be made of metal, such as copper, iron, aluminum, or stainless steel. The rear lock cylinder 22 can be made of metal, such as copper, iron, aluminum, or stainless steel. The pivot 23 can be made of metal, such as copper, iron, aluminum, or stainless steel. The materials of the front lock cylinder 21, the rear lock cylinder 22, and the pivot 23 can be the same, partially different, or all different.
[0039] In some embodiments, the cylinder assembly 20 is rotatably disposed within the lock housing 10. The front cylinder 21 is provided with a keyhole 213, which can be integrally formed with the front cylinder 21, or formed by machining after the front cylinder 21 is manufactured. During unlocking, the key 80 is inserted into the keyhole 213, and turning the key 80 causes the front cylinder 21 to rotate, thereby causing the rear cylinder 22 to rotate via the pivot 23. The rear cylinder 22 can connect with the lock's bolt, thus achieving unlocking.
[0040] In some embodiments, the pivot 23 connects the front lock cylinder 21 and the rear lock cylinder 22. The pivot 23 can be connected to the front lock cylinder 21 by snap-fit or bolt fastening, and the pivot 23 can be connected to the rear lock cylinder 22 by snap-fit or bolt fastening.
[0041] In some embodiments, the rotating shaft 23 may be cylindrical, and the clutch block 30 may be sleeved on the outer peripheral surface of the rotating shaft 23. A portion of the rotating shaft 23 may extend into the front lock cylinder 21, while another portion of the rotating shaft 23 may be located outside the front lock cylinder 21. The clutch block 30 may be sleeved on the portion of the rotating shaft 23 located outside the front lock cylinder 21.
[0042] In some embodiments, the driving element can be a motor. The Type-C interface 41 is connected to the driving element via signal connection, which can be Bluetooth, wire harness, or WiFi.
[0043] In some embodiments, the Type-C interface 41 may be connected to a circuit board, and the circuit board is connected to the driver signal.
[0044] In some embodiments, the material of the ball 52 can be metal, such as iron, copper, aluminum, stainless steel, etc.
[0045] In some embodiments, both the ball 52 and the first magnet 51 can be cylinders, and the axis of the ball 52 and the axis of the first magnet 51 coincide.
[0046] In some embodiments, the front locking cylinder 21, the rotating shaft 23, and the rear locking cylinder 22 can all be cylindrical, and the axes of the front locking cylinder 21, the rotating shaft 23, and the rear locking cylinder 22 can coincide, and the axis of the front locking cylinder 21 is parallel to the axis of the tumbler 52.
[0047] In some embodiments, the ball 52 and the first magnet 51 abut against each other, thereby realizing the transmission connection between the ball 52 and the first magnet 51.
[0048] In some embodiments, along the radial direction of the front lock cylinder 21, a portion of the lower pin 52 is located within the clutch block 30 or the front lock cylinder 21, and another portion of the lower pin 52 is located within the lock housing 10.
[0049] In the third position, part of the ball 52 is located inside the clutch block 30 and the other part is located inside the rotating shaft 23. At this time, along the circumference of the clutch block 30, the rotating shaft 23 cannot rotate relative to the clutch block 30, thereby locking the clutch block 30 and the rotating shaft 23.
[0050] In the fourth position, the pin 52 is located inside the pivot 23. At this time, along the circumference of the clutch block 30, the clutch block 30 can rotate relative to the lock housing 10, thereby releasing the lock between the clutch block 30 and the pivot 23.
[0051] During electrical unlocking, pin 52 is in the third position, meaning clutch block 30 and shaft 23 rotate synchronously. Key 80 is inserted into keyhole 213, and key 80 engages with Type-C interface 41. Type-C interface 41 drives first drive component 42 to rotate from the first position to the second position, at which point clutch block 30 can rotate relative to lock housing 10. Turning key 80 forward drives rear lock cylinder 22 to rotate via front lock cylinder 21 and shaft 23, thus unlocking the lock. It should be noted that clutch block 30 rotates during electrical unlocking.
[0052] During emergency unlocking, the drive unit is in the first position, at which point the clutch block 30 cannot rotate relative to the lock housing 10. When the key 80 is inserted into the keyhole 213, the second magnet 85 repels the first magnet 51, causing the rear lock cylinder 22 to move. At this point, the tumbler 52 moves from the third position to the fourth position, allowing the pivot 23 to rotate relative to the clutch block 30. Turning the key 80 clockwise, through the front lock cylinder 21 and the pivot 23, drives the rear lock cylinder 22 to rotate, thus unlocking the lock. It should be noted that during emergency unlocking, the clutch block 30 does not rotate.
[0053] The technical solution of this application embodiment, by setting a signal connection between the Type-C interface 41 and the driving component, allows the electric key 80 to be inserted into the lock hole 213 and cooperate with the Type-C interface 41, thereby driving the driving component to rotate to the second position, releasing the lock of the clutch block 30 and the rotating shaft 23, and turning the electric key 80 to achieve electrical unlocking. By setting a first magnet 51 and a pin 52 that are interconnected, after the key 80 is inserted into the lock hole 213, the second magnet 85 drives the pin 52 from the third position to the fourth position through the first magnet 51, releasing the lock of the clutch block 30 and the lock shell 10, and turning the key 80 to achieve emergency unlocking. While achieving emergency unlocking, compared with an external emergency unlocking mechanism, the Type-C interface lock cylinder 1 of this application is smaller in size, which is beneficial to improving the security and versatility of the Type-C interface lock cylinder 1. In addition, the lock cylinder assembly 20, the magnetic pin assembly 50 and the electrical assembly 40 are all set inside the lock shell 10, reducing the risk of dust entering the interior of the lock shell 10 and improving the sealing performance of the Type-C interface lock cylinder 1.
[0054] Please refer to Figures 1 to 4In some embodiments, the Type-C interface lock cylinder 1 further includes a locking pin 60, which is movably disposed on the clutch block 30. The first driving member 42 is a motor, which has a motor shaft 421 rotatably disposed on the rotating shaft 23. In the first position, the motor shaft 421 abuts against the locking pin 60, so that the locking pin 60 connects the clutch block 30 and the lock housing 10. In the second position, the motor shaft 421 separates from the locking pin 60, so that the locking pin 60 retracts from the lock housing 10.
[0055] In some embodiments, the locking pin 60 may be made of metal, such as iron, copper, aluminum, stainless steel, etc.
[0056] In some embodiments, a locking pin 60 is movably disposed on the clutch block 30 along the axial direction of the clutch block 30.
[0057] In the first position, the motor shaft 421 abuts against the locking pin 60, thereby limiting the locking pin 60 through the motor shaft 421, so that the locking pin 60 is always connected to the clutch block 30 and the lock housing 10.
[0058] In the second position, the motor shaft 421 rotates, causing the motor shaft 421 to separate from the locking pin 60, and the locking pin 60 is no longer limited. The locking pin 60 exits the lock housing 10, thereby releasing the locking pin 60 from the clutch block 30 and the lock housing 10.
[0059] The technical solution of this application embodiment involves setting a locking pin 60 to cooperate with the clutch block 30 and the lock housing 10. In the first position, the motor shaft 421 abuts against the locking pin 60, thereby locking the lock housing 10 and the clutch block 30. In the second position, the motor shaft 421 separates from the locking pin 60, causing the locking pin 60 to retract from the lock housing 10, thus releasing the lock between the lock housing 10 and the clutch block 30, which improves the convenience of electrical unlocking.
[0060] Please refer to Figures 1 to 4 In some embodiments, the lock housing 10 is provided with a first mounting groove 11, the clutch block 30 is provided with a clutch block hole 31, and the rotating shaft 23 is provided with a clearance groove 231. The clutch block hole 31 communicates with the clearance groove 231, and the motor shaft 421 is rotatably disposed in the clearance groove 231. In the first position, the motor shaft 421 abuts against one end of the locking pin 60, and the other end of the locking pin 60 extends into the first mounting groove 11. In the second position, one end of the locking pin 60 extends into the clearance groove 231, and the other end of the locking pin 60 extends from the first mounting groove 11 into the clutch block hole 31.
[0061] In some embodiments, the lock housing 10 may be provided with a first mounting groove 11. The first mounting groove 11 may be integrally formed with the lock housing 10, or the first mounting groove 11 may be formed by machining after the lock housing 10 is manufactured.
[0062] In some embodiments, the clutch block 30 may be provided with a clutch block hole 31. The clutch block hole 31 may be integrally formed with the clutch block 30, or the clutch block hole 31 may be formed by machining after the clutch block 30 is manufactured.
[0063] In some embodiments, the rotating shaft 23 may be provided with a relief groove 231. The relief groove 231 may be integrally formed with the rotating shaft 23, or the relief groove 231 may be formed by machining after the rotating shaft 23 is machined.
[0064] It is understood that the clutch block 30 is sleeved on the rotating shaft 23, and the clutch block hole 31 extends radially along the clutch block 30 to the outer peripheral surface of the clutch block hole 31. In the locked state, the first mounting groove 11, the clutch block hole 31 and the clearance groove 231 correspond radially along the clutch block 30.
[0065] In the first position, a portion of the locking pin 60 is located in the first mounting groove 11, and the other portion of the locking pin 60 is located in the clutch block hole 31 and abuts against the motor shaft 421. That is, the motor shaft 421 blocks the clutch block hole 31, so that the locking pin 60 cannot enter the clearance groove 231, thereby locking the clutch block 30 with the lock housing 10, that is, the clutch block 30 cannot rotate relative to the lock housing 10.
[0066] In the second position, the motor shaft 421 rotates, thus removing the motor shaft 421 from contact with the locking pin 60. When the key 80 is turned, the key 80 drives the front lock cylinder 21 to rotate, which in turn drives the rotating shaft 23 to rotate. Since the pin 52 is in the third position, i.e., the clutch block 30 is locked to the rotating shaft 23, the clutch block 30 tends to rotate relative to the lock housing 10. At this time, the lock housing 10 presses the locking pin 60, forcing the locking pin 60 into the relief groove 231. Part of the locking pin 60 extends from the clutch block hole 31 into the relief groove 231, and the other part of the locking pin 60 extends from the first mounting groove 11 into the clutch block hole 31. This releases the lock between the clutch block 30 and the lock housing 10, allowing the clutch block 30 to rotate relative to the lock housing 10.
[0067] In some embodiments, the rotating shaft 23 may be provided with a limiting part 233, which may be disposed in the clearance groove 231. The rotating shaft 23 may be integrally formed with the limiting part 233, or the limiting part 233 may be machined after the rotating shaft 23 is machined.
[0068] When the drive unit rotates from the first position to the second position, the motor shaft 421 rotates until one end of the motor shaft 421 abuts against the limiting part 233 of the rotating shaft 23, and the motor shaft 421 stops rotating. At this time, the motor shaft 421 no longer blocks the clutch block hole 31.
[0069] Similarly, when the drive unit rotates from the second position to the first position, the motor shaft 421 reverses until the other end of the motor shaft 421 abuts against the limiting part 233 of the rotating shaft 23, at which point the motor shaft 421 stops rotating and the motor shaft 421 blocks the clutch block hole 31.
[0070] The technical solution of this application embodiment, by setting a first mounting groove 11, a clutch block hole 31, and a clearance groove 231 to cooperate with the locking pin 60, in the first position, one end of the locking pin 60 is located in the clutch block hole 31, and the other end extends into the first mounting groove 11, thereby locking the lock housing 10 and the clutch block 30. In the second position, the motor shaft 421 separates from the locking pin 60, causing the locking pin 60 to retract from the lock housing 10. One end of the locking pin 60 extends into the clearance groove 231, and the other end of the locking pin 60 extends from the first mounting groove 11 into the clutch block hole 31, thereby releasing the lock between the lock housing 10 and the clutch block 30, which improves the convenience of electrical unlocking.
[0071] Please refer to Figures 1 to 4 In some embodiments, the Type-C interface lock cylinder 1 further includes a locking pin spring 61, one end of which is connected to the inner wall of the clutch block hole 31, and the other end of which is connected to the locking pin 60. The electrical assembly 40 also includes a torsion spring 43, one end of which is connected to the motor shaft 421, and the other end of which is connected to the front lock cylinder 21. During electrical unlocking, the motor shaft 421 rotates from the first position to the second position, the torsion spring 43 stores force, and the rotating shaft 23 drives the clutch block 30 to rotate, so that one end of the locking pin 60 extends into the relief groove 231, and the locking pin spring 61 stores force. When electrically locked, the torsion spring 43 drives the motor shaft 421 to move from the second position to the first position, reverses the key 80, and the rotating shaft 23 drives the clutch block 30 to reverse. The locking pin spring 61 drives one end of the locking pin 60 to retract into the clutch block hole 31 through the relief groove 231, and drives the other end of the locking pin 60 to extend into the first mounting groove 11 through the clutch block hole 31.
[0072] When electrically locked, the torsion spring 43 tends to reset the motor shaft 421, and the locking pin spring 61 tends to reset the locking pin 60. Reversing the key 80 causes the front lock cylinder 21 to rotate, which in turn rotates the shaft 23 until the shaft 23 and clutch block 30 are reset, meaning the first mounting groove 11 and clutch block hole 31 correspond. At this point, the locking pin spring 61 resets the locking pin 60, causing a portion of the locking pin 60 to enter the clutch block hole 31 through the clearance groove 231, and the other portion to enter the first mounting groove 11 through the clutch block hole 31. This means the locking pin 60 exits the clearance groove 231, giving the motor shaft 421 space to reset, and the torsion spring 43 resets the motor shaft 421.
[0073] The technical solution of this application embodiment uses a torsion spring 43 to reset the motor shaft 421 and a locking pin spring 61 to reset the locking pin 60, which helps to improve the convenience of electrical locking.
[0074] Please refer to Figure 1 , Figure 5 and Figure 6 In some embodiments, the front lock cylinder 21 has a first mounting hole 211, the rotating shaft 23 has a first through hole 232, and the clutch block 30 has a second mounting hole 32. The magnetic tumbler assembly 50 also includes a cylindrical pin 53, which drivesly connects the first magnet 51 and the tumbler 52. The first magnet 51 is movably disposed in the first mounting hole 211. In the third position, one end of the cylindrical pin 53 is located in the first mounting hole 211, and the other end of the cylindrical pin 53 is located in the first through hole 232. One end of the tumbler 52 is located in the first through hole 232, and the other end of the tumbler 52 is located in the second mounting hole 32. In the fourth position, one end of the cylindrical pin 53 is located in the first mounting hole 211, the other end of the cylindrical pin 53 is located in the first through hole 232, and all the tumblers 52 are located in the second mounting hole 32.
[0075] In some embodiments, the front lock cylinder 21 may be provided with a first mounting hole 211. The first mounting hole 211 may be integrally formed with the front lock cylinder 21, or it may be formed by machining after the front lock cylinder 21 is manufactured. The first mounting hole 211 may extend along the axial direction of the front lock cylinder 21.
[0076] In some embodiments, the rotating shaft 23 may be provided with a first through hole 232. The first through hole 232 may be integrally formed with the rotating shaft 23, or it may be formed by machining after the rotating shaft 23 is manufactured. The first through hole 232 may extend along the axial direction of the rotating shaft 23.
[0077] In some embodiments, the clutch block 30 may be provided with a second mounting hole 32. The second mounting hole 32 may be integrally formed with the clutch block 30, or it may be formed by machining after the clutch block 30 is manufactured. The second mounting hole 32 may extend along the axial direction of the clutch block 30.
[0078] In some embodiments, the cylindrical pin 53 can be made of metal, such as copper, iron, aluminum, stainless steel, etc.
[0079] In some embodiments, the axis of the cylindrical pin 53 may be parallel to the axis of the front lock cylinder 21.
[0080] In some embodiments, one end of the cylindrical pin 53 abuts against the first magnet 51, and the other end of the cylindrical pin 53 abuts against the ball 52.
[0081] In some embodiments, the second magnet 85 may have the same magnetism as the first magnet 51. In the third position, the first magnet 51 is located in the first mounting hole 211, a portion of the cylindrical pin 53 is located in the first mounting hole 211, another portion of the cylindrical pin 53 is located in the first through hole 232, a portion of the ball 52 is located in the first through hole 232, and another portion of the ball 52 is located in the second mounting hole 32, thereby locking the rotating shaft 23 and the clutch block 30 together, meaning the clutch block 30 can rotate with the rotating shaft 23. In the fourth position, the first magnet 51 is located in the first mounting hole 211, a portion of the cylindrical pin 53 is located in the first mounting hole 211, another portion of the cylindrical pin 53 is located in the first through hole 232, and all of the ball 52 is located in the second mounting hole 32, thereby releasing the locking between the rotating shaft 23 and the clutch block 30, meaning the clutch block 30 cannot rotate with the rotating shaft 23.
[0082] In some embodiments, the second magnet 85 may have a magnetic field opposite to that of the first magnet 51. In the third position, the first magnet 51 is located in the first mounting hole 211, a portion of the cylindrical pin 53 is located in the first mounting hole 211, a portion of the cylindrical pin 53 is located in the first through hole 232, a portion of the cylindrical pin 53 is located in the second mounting hole 32, and the ball 52 is located in the second mounting hole 32. This allows the cylindrical pin 53 to lock the rotating shaft 23 and the clutch block 30, meaning the clutch block 30 can rotate with the rotating shaft 23. In the fourth position, the first magnet 51 is located in the first mounting hole 211, a portion of the cylindrical pin 53 is located in the first mounting hole 211, another portion of the cylindrical pin 53 is located in the first through hole 232, and the ball 52 is located in the second mounting hole 32. This releases the locking between the rotating shaft 23 and the clutch block 30, meaning the clutch block 30 cannot rotate with the rotating shaft 23.
[0083] The technical solution of this application embodiment, by providing a first through hole 232 and a second mounting hole 32 to cooperate with the ball 52, in the third position, one end of the ball 52 is located in the first through hole 232, and the other end of the ball 52 is located in the second mounting hole 32, thereby locking the rotating shaft 23 and the clutch block 30. In the fourth position, all the balls 52 are located in the second mounting hole 32, thereby releasing the lock between the rotating shaft 23 and the clutch block 30, which improves the convenience of emergency unlocking.
[0084] Please refer to Figure 1 , Figure 5 and Figure 6In some embodiments, the magnetic pin assembly 50 further includes a pin spring 54, one end of which is connected to the pin 52, and the other end of which is connected to the wall of the second mounting hole 32. In case of emergency unlocking, the key 80 is inserted into the lock hole 213, and the pin 52 moves from the third position to the fourth position, storing force in the pin spring 54. In case of locking, reversing the key 80 causes the rear lock cylinder 22 to rotate via the front lock cylinder 21 and the pivot 23, thus locking the pin. The pin spring 54 then drives the pin 52 to move from the fourth position to the third position.
[0085] In some embodiments, one end of the ball 52 is connected to the ball spring 54, and the other end of the ball 52 is connected to the cylindrical pin 53.
[0086] During emergency unlocking, along the axial direction of the lock housing 10, the second magnet 85 of the key 80 drives the first magnet 51, causing the first magnet 51 to move closer to the clutch block 30. The first magnet 51 pushes the tumbler 52 away from the front lock cylinder 21 through the cylindrical pin 53, causing the tumbler spring 54 to store force.
[0087] When locked, the key 80 is pulled out, and along the axial direction of the lock case 10, the tumbler spring 54 drives the tumbler 52 to move closer to the front lock cylinder 21. The tumbler 52 drives the first magnet 51 to move away from the clutch block 30 through the cylindrical pin 53.
[0088] The technical solution of this application embodiment, by setting a ball spring 54, realizes the reset of the ball 52, which helps to improve the convenience of locking.
[0089] Please refer to Figure 1 , Figure 5 and Figure 6 In some embodiments, there are multiple magnetic pin assemblies 50, which are spaced apart around the axis of the front lock cylinder 21. At least two of the magnetic pin assemblies 50 have first magnets 51 with opposite magnetic properties. The key 80 is provided with multiple second magnets 85, which correspond one-to-one with the multiple first magnets 51, and the second magnets 85 have the same magnetic properties as the corresponding first magnets 51.
[0090] In some embodiments, the number of magnetic ball components 50 is multiple, that is, the number of balls 52 and the number of first magnets 51 are both multiple. The number of magnetic ball components 50 can be two, three, four, etc.
[0091] Understandably, the two first magnets 51 have opposite magnetic properties. Therefore, during emergency unlocking, two second magnets 85 with opposite magnetic properties are needed, each corresponding to one of the two first magnets 51, to move the pin 52 from the third position to the fourth position. If two second magnets 85 with identical magnetic properties are used, each corresponding to one of the two first magnets 51, only one of the two first magnets 51 can drive one pin 52 to move from the third position to the fourth position; the other pin 52 cannot move from the third position to the fourth position, thus preventing emergency unlocking.
[0092] The technical solution of this application embodiment, by setting multiple magnetic tumbler assemblies 50, and the first magnets 51 of at least two magnetic tumbler assemblies 50 having opposite magnetism, reduces the risk of unlocking caused by driving multiple first magnets 51 through magnets with the same magnetism, which is beneficial to improving the security of the Type-C interface lock cylinder 1.
[0093] Please refer to Figure 1 , Figure 5 and Figure 6 In some embodiments, the number of magnetic pin assemblies 50 is four, with two magnetic pin assemblies 50 on each side of the lock hole 213, and the magnetic pin assemblies 50 on both sides are symmetrically arranged. Among them, around the axis of the front lock cylinder 21, the magnetic properties of two adjacent first magnets 51 are opposite.
[0094] In some embodiments, there are four magnetic ball bearing assemblies 50, arranged around the axis of the front lock cylinder 21. These four magnetic ball bearing assemblies 50 are designated as a first magnetic ball bearing assembly 50, a second magnetic ball bearing assembly 50, a third magnetic ball bearing assembly 50, and a fourth magnetic ball bearing assembly 50. The magnetism of the first magnet 51 in the first magnetic ball bearing assembly 50 is opposite to that of the first magnet 51 in the second magnetic ball bearing assembly 50; the magnetism of the first magnet 51 in the second magnetic ball bearing assembly 50 is opposite to that of the first magnet 51 in the third magnetic ball bearing assembly 50; and the magnetism of the first magnet 51 in the third magnetic ball bearing assembly 50 is opposite to that of the first magnet 51 in the fourth magnetic ball bearing assembly 50.
[0095] Correspondingly, there are four second magnets 85, arranged around the axis of the front lock cylinder 21. The four second magnets 85 are designated as the first, second, third, and fourth second magnets 85. The magnetism of the first second magnet 85 is opposite to that of the second second magnet 85, the magnetism of the second second magnet 85 is opposite to that of the third second magnet 85, and the magnetism of the third second magnet 85 is opposite to that of the fourth second magnet 85.
[0096] It should be noted that the first first magnet 51 corresponds to the first second magnet 85, the second first magnet 51 corresponds to the second second magnet 85, the third first magnet 51 corresponds to the third second magnet 85, and the fourth first magnet 51 corresponds to the fourth second magnet 85. The unlocking head 83 of the key 80 is flat. Along the length of the unlocking head 83, the first second magnet 85 and the second second magnet 85 are positioned opposite each other, and the third second magnet 85 and the fourth second magnet 85 are positioned opposite each other. Along the width of the unlocking head 83, the first second magnet 85 and the third second magnet 85 are positioned opposite each other, and the second second magnet 85 and the fourth second magnet 85 are positioned opposite each other. Therefore, when the unlocking head 83 is inserted into the keyhole 213, it is not necessary to distinguish between the front and back of the unlocking head 83 to achieve emergency unlocking.
[0097] Understandably, following the same principle, the number of magnetic ball components 50 can also be six, eight, etc.
[0098] In some embodiments, the number of first mounting holes 211, first through holes 232, and second mounting holes 32 may be the same. Furthermore, the number of first mounting holes 211, first through holes 232, and second mounting holes 32 may be greater than or equal to the number of magnetic pin assemblies 50. For example, the number of first mounting holes 211, first through holes 232, and second mounting holes 32 may be six, and the number of magnetic pin assemblies 50 may be four or six. The Type-C interface lock cylinder 1 is generally used in power applications. Based on security level requirements, the Type-C interface lock cylinder 1 can be divided into an auxiliary control lock cylinder and an anti-mislocking cylinder. The auxiliary control lock cylinder is used for equipment with lower security levels, while the anti-mislocking cylinder is used for equipment with higher security levels.
[0099] Taking a case where there are six mounting holes (first mounting hole 211, first through hole 232, and second mounting hole 32), the auxiliary control lock cylinder has six mounting holes (first mounting hole 211, first through hole 232, and second mounting hole 32) and four magnetic pin assemblies 50. The arrangement and installation position of the magnetic pin assemblies 50 in each auxiliary control lock cylinder can be the same, allowing each auxiliary control lock cylinder to be unlocked using the same key 80. Conversely, the anti-misoperation lock cylinder has six mounting holes (first mounting hole 211, first through hole 232, and second mounting hole 32) and six magnetic pin assemblies. The arrangement and installation position of the magnetic pin assemblies 50 in each anti-misoperation lock cylinder can be different, allowing each anti-misoperation lock cylinder to be unlocked only using a specific key 80.
[0100] The technical solution of this application embodiment sets two adjacent first magnets 51 to have opposite magnetic properties by wrapping around the axis of the front lock cylinder 21, so that when the key 80 is inserted to unlock, it is not necessary to distinguish the magnetic properties of each second magnet 85, which helps to improve the convenience of emergency unlocking.
[0101] Please refer to Figure 1 and refer to Figures 7 to 9 , Figure 7 This is a schematic diagram of the lock housing structure provided in some embodiments of this application. Figure 8 This is a schematic diagram of the front locking cylinder provided in some embodiments of this application. Figure 9 This is a schematic diagram of the key structure provided in some embodiments of this application. In some embodiments, the Type-C interface lock cylinder 1 further includes a steel ball 70. The lock housing 10 is provided with a second mounting groove 12, the front lock cylinder 21 is provided with a second through hole 212, the second through hole 212 is correspondingly provided with the second mounting groove 12, and the second through hole 212 communicates with the lock hole 213, and the key 80 is provided with a third mounting groove 81. In the locked state, a part of the steel ball 70 is located in the second mounting groove 12, and the other part of the steel ball 70 passes through the second through hole 212 and extends into the lock hole 213 from the side of the second through hole 212 away from the second mounting groove 12. In the unlocking state, the key 80 is inserted into the lock hole 213, and when the key 80 is turned clockwise, a part of the steel ball 70 enters the second through hole 212 from the second mounting groove 12, and the other part of the steel ball 70 extends into the third mounting groove 81.
[0102] In some embodiments, the lock housing 10 is provided with a second mounting groove 12. The second mounting groove 12 can be integrally formed with the lock housing 10, or it can be formed by machining after the lock housing 10 is manufactured.
[0103] In some embodiments, the front lock cylinder 21 is provided with a second through hole 212. The front lock cylinder 21 can be integrally formed with the second through hole 212, or the second through hole 212 can be formed by machining after the front lock cylinder 21 is manufactured. The through hole can extend along the outer peripheral surface of the front lock cylinder 21 to the inner wall of the lock hole 213.
[0104] When unlocking, key 80 is inserted into keyhole 213. Turning key 80 clockwise causes the front lock cylinder 21 to rotate relative to the lock housing 10. This causes the lock housing 10 to push steel ball 70 into keyhole 213. Part of steel ball 70 enters the second through hole 212 through the second mounting groove 12, and the other part enters the third mounting groove 81 through the second through hole 212. At this point, steel ball 70 locks key 80 and front lock cylinder 21.
[0105] The technical solution of this application embodiment uses the steel ball 70 to cooperate with the second mounting groove 12 of the lock shell 10, the second through hole 212 of the front lock cylinder 21 and the key 80, so that when the key 80 is used to unlock, the steel ball 70 cooperates with the front lock cylinder 21 and the key 80, reducing the risk of the key 80 being pulled out.
[0106] Please refer to Figure 1 , Figure 5 and Figure 6In some embodiments, the rear lock cylinder 22 has a fifth mounting groove 221 at one end opposite to the front lock cylinder 21. One end of the rotating shaft 23 is connected to the front lock cylinder 21, and the other end of the rotating shaft 23 passes through the rear lock cylinder 22 and is located in the fifth mounting groove 221. The Type-C interface lock cylinder 1 also includes a retaining ring 90, which is sleeved on the other end of the rotating shaft 23 and abuts against the bottom wall of the fifth mounting groove 221.
[0107] In some embodiments, the rear lock cylinder 22 is provided with a fifth mounting groove 221. The fifth mounting groove 221 can be integrally formed with the rear lock cylinder 22, or it can be formed by machining after the rear lock cylinder 22 is manufactured. The fifth mounting groove 221 is disposed on the end face of the rear lock cylinder 22 opposite to the front lock cylinder 21.
[0108] In some embodiments, along the axial direction of the rotating shaft 23, one end of the rotating shaft 23 is connected to the front lock cylinder 21, and the other end of the rotating shaft 23 passes through the rear lock cylinder 22 and is located in the fifth mounting groove 221. The clutch block 30 is sleeved on the portion of the rotating shaft 23 located between the front lock cylinder 21 and the rear lock cylinder 22. The retaining ring 90 is sleeved on the other end of the rotating shaft 23 and abuts against the bottom wall of the fifth mounting groove 221.
[0109] The technical solution of this application embodiment connects the rotating shaft 23 and the rear lock cylinder 22 through the retaining ring 90, which helps to improve the convenience of connecting the rotating shaft 23 and the rear lock cylinder 22.
[0110] In some embodiments, the Type-C interface lock cylinder 1 further includes a first sealing ring 91, which is sleeved on the outer peripheral surface of the front lock cylinder 21 to seal the gap between the front lock cylinder 21 and the lock shell 10.
[0111] In some embodiments, the Type-C interface lock cylinder 1 further includes a second sealing ring 92, which is sleeved on the outer peripheral surface of the rotating shaft 23 to seal the gap between the rotating shaft 23 and the rear lock cylinder 22.
[0112] In some embodiments, the Type-C interface lock cylinder 1 further includes a third sealing ring 93, which is sleeved on the outer peripheral surface of the rear lock cylinder 22 to seal the gap between the rear lock cylinder 22 and the lock shell 10.
[0113] Please refer to Figure 1 , Figure 5 and Figure 6 and refer to Figure 10 and Figure 11 , Figure 10 A schematic diagram illustrating the authorized locations provided in some embodiments of this application. Figure 11This is a schematic diagram illustrating unauthorized positions provided in some embodiments of this application. In a second aspect, this application provides a key 80 for unlocking a Type-C interface lock cylinder 1 with emergency unlocking as described in any embodiment of the first aspect. The key 80 includes a housing 82, an unlocking head 83, a second magnet 85, and a second driving member 86. The unlocking head 83 is connected to the housing 82 and has a sixth mounting groove 84. The second magnet 85 is movably disposed in the sixth mounting groove 84. The second driving member 86 is disposed in the housing 82 and is drively connected to the second magnet 85. The second magnet 85 has an authorized position and an unauthorized position. In the authorized position, the end of the second magnet 85 facing away from the housing 82 abuts against the bottom wall of the sixth mounting groove 84; in the unauthorized position, the end of the second magnet 85 facing away from the housing 82 is spaced apart from the bottom wall of the sixth mounting groove 84. The key 80 has an emergency unlocking mode and an electrical unlocking mode. During emergency unlocking, key 80 is in emergency unlocking mode, unlocking head 83 is inserted into keyhole 213, second drive component 86 moves second magnet 85 from unauthorized position to authorized position, and second magnet 85, through first magnet 51, moves tumbler 52 from third position to fourth position. During electrical unlocking, key 80 is in electrical unlocking mode, second magnet 85 is in unauthorized position, unlocking head 83 is inserted into keyhole 213 and engages with Type-C interface 41.
[0114] In some embodiments, the housing 82 and the unlocking head 83 are connected, and the connection method can be adhesive, bolt fastening, etc.
[0115] In some embodiments, the second drive element 86 may be a solenoid.
[0116] During emergency unlocking, key 80 is in emergency unlocking mode, unlocking head 83 is inserted into lock hole 213, and second drive component 86 drives second magnet 85 from unauthorized position to authorized position. At this time, second magnet 85 abuts against the bottom wall of sixth mounting groove 84, that is, unlocking head 83 is inserted into lock hole 213. The distance between second magnet 85 and first magnet 51 is relatively close, and second magnet 85 can drive first magnet 51 to move through magnetic force, thereby driving tumbler 52 to move from third position to fourth position.
[0117] During electrical unlocking, key 80 is in electrical unlocking mode, and second magnet 85 is in the unauthorized position. At this time, second magnet 85 is separated from the bottom wall of sixth mounting slot 84, that is, unlocking head 83 is inserted into lock hole 213. The distance between second magnet 85 and first magnet 51 is relatively far, and second magnet 85 cannot drive first magnet 51 to move by magnetic force, so that tumbler 52 is in the third position. Unlocking head 83 is inserted into lock hole 213 and cooperates with Type-C interface 41 to achieve electrical unlocking.
[0118] Because there are a large number of second magnets 85, and to keep the key 80 relatively small, the power of the second driving component 86 is also relatively low. In some embodiments, taking six second magnets 85 as an example, the positions of four second magnets 85 can be fixed, and the second magnets 85 are always in the authorized position. The positions of the remaining two second magnets 85 can change; that is, under normal circumstances, the two second magnets 85 are in the unauthorized position. In case of emergency unlocking, the second driving component 86 moves the two second magnets 85 from the unauthorized position to the authorized position, thereby unlocking the key.
[0119] The technical solution of this application embodiment improves the convenience of unlocking by setting an emergency unlocking mode and an electrical unlocking mode on the key 80, while also having an emergency unlocking function to improve security.
[0120] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
