Description

Technical Field

[0001] This application relates to the field of electronic locks, and more specifically, to an electronic lock cylinder and lock head. Background Technology

[0002] Existing electronic locks typically use a drive module to move a transmission mechanism, which in turn drives the clutch to switch between the unlock and lock positions. When the drive module moves the transmission mechanism, it is easy for it to rotate too many times. This can cause the drive module to continue rotating the transmission mechanism after the clutch has rotated to the lock or unlock position, leading to the drive module stalling. This, in turn, increases the current flowing through the drive module, thereby increasing the risk of damage to the drive module. Utility Model Content

[0003] This application provides an electronic lock cylinder and lock head that can reduce the probability of drive module stalling, thereby reducing the risk of drive module damage.

[0004] In a first aspect, embodiments of this application provide an electronic lock cylinder, including a housing, a circuit control module, a Type-C male connector, a drive module, a transmission rod, a locking block, and a first spring. The circuit control module, the Type-C male connector, the drive module, and the transmission rod are disposed within the housing; one end of the Type-C male connector extends out of the housing, and the other end is connected to the circuit control module; the drive module is drively connected to the transmission rod; the locking block is movably sleeved on the transmission rod, and the locking block has an unlocked position extending out of the housing and a locked position retracted into the housing, with a receiving cavity formed inside the locking block; the first spring is disposed within the receiving cavity and sleeved on the transmission rod, and a first limiting protrusion is provided on the outer circumferential surface of the transmission rod, the first limiting protrusion passing between two turns of the first spring's spiral; the drive module drives the transmission rod to rotate forward and backward, so that the transmission rod, through the first spring, pushes the locking block to the locked position and the unlocked position.

[0005] Since the first spring is sleeved on the transmission rod and located within the accommodating cavity, and the first limiting protrusion passes between the two turns of the first spring's spiral, when the first limiting protrusion rotates with the transmission rod, it moves along the spiral of the first spring. This causes the first spring to move along the transmission rod and abut against the two walls of the accommodating cavity in its direction of movement. Consequently, the first spring provides elastic force to the accommodating cavity, thereby switching the locking block between the locked and unlocked positions.

[0006] Specifically, taking an external device (such as a mobile phone) as an example, power is supplied to the drive module via a Type-C male connector, causing the drive module to switch the locking block from the unlocked position to the locked position. In the unlocked position, the portion of the first spring located between the wall of the accommodating cavity near the unlocked position and the first limiting protrusion reaches its maximum length in the spring's extension direction. This allows the portion of the first spring to apply an elastic force to the wall of the accommodating cavity near the unlocked position, thus keeping the locking block in the unlocked position. When switching the locking block from the unlocked position to the locked position, the drive module drives the transmission rod to rotate forward, causing the length of the portion of the first spring located between the wall of the accommodating cavity near the unlocked position and the first limiting protrusion in the spring's extension direction to gradually decrease, and causing the length of the portion of the first spring located between the wall of the accommodating cavity near the locked position and the first limiting protrusion in the spring's extension direction to gradually increase. This, on the one hand, causes the portion of the first spring located between the wall of the accommodating cavity near the unlocked position and the first limiting protrusion to lift the portion of the first spring located between the wall of the accommodating cavity near the unlocked position towards the wall of the accommodating cavity near the unlocked position. The supplied elastic force gradually decreases. On the other hand, the portion of the first spring located between the wall of the accommodating cavity near the locking position and the first limiting protrusion provides a gradually increasing elastic force to the wall of the accommodating cavity near the locking position, thereby driving the locking block to switch from the unlocked position to the locked position. When the locking block switches to the locked position and the drive module tends to continue rotating, the transmission rod continues to rotate in the forward direction, so that the first limiting protrusion continues to move along the extension direction of the first spring. This causes the length of the portion of the first spring located between the wall of the accommodating cavity near the locking position and the first limiting protrusion in the extension direction of the first spring to further increase, so as to provide a greater elastic force to the wall of the accommodating cavity near the locking position, until the first spring is completely located between the wall of the accommodating cavity near the locking position and the first limiting protrusion. At this time, the first limiting protrusion and the spiral abutment of the end of the first spring away from the locking position are engaged. Thus, when the transmission rod rotates in the forward direction to drive the first limiting protrusion to rotate, the spiral abutment of the first limiting protrusion and the end of the first spring away from the locking position is engaged in a reciprocating cycle. This allows the drive module to continue rotating.

[0007] In the above technical solution, when the locking block switches to the locked or unlocked position and the drive module tends to continue rotating, the drive module can continue to rotate, reducing the probability of the drive module stalling and thus reducing the risk of damage to the drive module.

[0008] In some embodiments, the locking block may include a body and a protrusion, the protrusion protruding from one end of the body, and one end of the housing having a second through hole; when in the unlocked position, a portion of the protrusion extends out of the housing through the second through hole; when in the unlocked position, a portion of the protrusion is located inside the second through hole; the outer peripheral side of the body protrudes from the outer peripheral side of the protrusion to form a stepped surface on the outer periphery of the locking block, the stepped surface being used to abut against the inner surface of the wall portion of the housing having the second through hole.

[0009] In the above technical solution, the stepped surface abuts against the inner surface of the wall portion of the outer shell with the second through hole, thereby restricting the locking block from leaving the outer shell and limiting the range of movement of the locking block, thus improving the reliability of the lock cylinder's unlocking and locking. The structure is simple and easy to implement.

[0010] In some embodiments, the cavity wall of the receiving cavity is provided with a limiting groove extending axially along the transmission rod; the two ends of the first spring are provided with limiting portions, and both limiting portions are inserted into the limiting groove.

[0011] In the above technical solution, by inserting both limiting parts into the limiting groove, the first spring can move along the axial direction of the transmission rod while the rotation of the first spring relative to the locking block is restricted. The structure is simple and easy to implement.

[0012] In some embodiments, the Type-C male connector and the locking block are located at opposite ends of the housing in its axial direction; the drive module and the transmission rod are arranged radially along the housing.

[0013] In the above technical solution, the Type-C male connector and the locking block are located at opposite ends of the housing in its axial direction, so as to reduce the risk of the Type-C male connector interfering with the movement of the locking block when the locking block switches between the locked and unlocked positions; at the same time, the drive module and the transmission rod are arranged along the radial direction, so that the drive module and the transmission rod jointly occupy part of the space of the housing in its axial direction, thereby reducing the size of the housing in its axial direction compared with the case where the drive module and the transmission rod are arranged along the axial direction of the housing, which is conducive to reducing the size of the electronic lock cylinder in its axial direction.

[0014] In some embodiments, the drive module further includes a motor, a drive gear, and a driven gear; the drive gear is mounted on the output shaft of the motor; the driven gear is mounted on the transmission rod and meshes with the drive gear.

[0015] In the above technical solution, by setting a driving gear and a driven gear, and by the meshing of the driving gear and the driven gear, the drive module drives the transmission rod to rotate. On the one hand, compared with chain drive and belt drive, no additional tension space is required, which makes the internal structure of the electronic lock core more compact and reduces the space occupied by the transmission mechanism between the drive module and the transmission rod in the housing, which is conducive to reducing the volume of the housing. On the other hand, the drive module and the transmission rod are arranged radially along the housing, and the output shaft of the drive module drives the transmission rod to rotate in the forward or reverse direction, which is simple in structure and easy to implement.

[0016] In some embodiments, the motor is a coreless motor.

[0017] In the above technical solution, the hollow cup motor eliminates the traditional silicon steel sheet stacking structure through the iron coreless rotor design, and the rotor is composed only of cup-shaped windings and commutators, eliminating the iron core support components. As a result, it is smaller in size than the traditional motor, thereby reducing the space occupied in the housing and helping to reduce the size of the housing, which in turn helps to reduce the size of the electronic lock cylinder.

[0018] In a second aspect, embodiments of this application provide an electronic lock cylinder, including a lock housing, a lever, and an external drive module; the external drive module includes an external knob, a first rotating shaft, and an electronic lock cylinder as described in any embodiment of the first aspect. The electronic lock cylinder and the first rotating shaft are disposed within the lock housing. The first rotating shaft has a groove that cooperates with the locking block. The groove is offset from the central axis of the first rotating shaft. The external knob is located at one end of the lock housing and connected to the outer shell. The lever is throttle-connected to the first rotating shaft. When the locking block is in the unlocked position, the locking block enters the groove, and the rotation of the electronic lock cylinder can drive the first rotating shaft to rotate, thereby driving the lever to rotate. When the locking block is in the locked position, the locking block exits the groove, and the electronic lock cylinder can rotate freely relative to the first rotating shaft.

[0019] Specifically, when unlocking and locking the electronic lock, an external device (such as a mobile phone) supplies power to the drive module via a Type-C male connector. The drive module then drives the transmission rod to rotate in the reverse direction, which in turn pushes the locking block to the unlock position via a first spring. This causes the locking block to enter the groove. At this time, an external force is applied to the electronic lock cylinder via an external knob to rotate the electronic lock cylinder, which in turn rotates the first rotating shaft, which in turn rotates the toggle block, allowing the electronic lock to switch between the unlocked and locked states. When unlocking the electronic lock is not required, the external device (such as a mobile phone) supplies power to the drive module via a Type-C male connector. The drive module then drives the transmission rod to rotate in the forward direction, which in turn pushes the locking block to the locked position via a first spring. The locking block exits the groove, and the electronic lock cylinder can rotate freely relative to the first rotating shaft. This prevents the external knob from rotating the electronic lock cylinder and thus keeps the toggle block rotating, thereby fixing the electronic lock in either the unlocked or locked state.

[0020] In the above technical solution, the transmission rod is driven to rotate by the drive module, so that the transmission rod drives the locking block to the unlocked or locked position, so that the outer knob can drive the lever to rotate, or cannot drive the lever to rotate. On the one hand, compared with the case where the drive module directly drives the rod and lever to rotate, the torque required by the drive module is reduced, which is conducive to using a drive module with less power, and thus conducive to reducing the size of the drive module. On the other hand, the first aspect provides electronic lock core control of the transmission connection and disengagement between the outer knob and the lever, which is simple in structure and easy to implement.

[0021] In some embodiments, the door drive module further includes a dust cover; the dust cover is detachably fitted onto the end of the external knob away from the electronic lock cylinder, and the Type-C male connector is located inside the dust cover.

[0022] In the above technical solution, the Type-C male connector is located inside the dust cover, so that when not in use, the dust cover can reduce the risk of external dust falling on the Type-C male connector. At the same time, since the dust cover is detachably fitted on the end of the external knob away from the drive module inside the door, the risk of the dust cover interfering with the connection between external devices and the Type-C male connector is reduced.

[0023] In some embodiments, the electronic lock cylinder further includes a clutch assembly and an in-door drive module. The clutch assembly is disposed between the in-door drive module and the out-of-door drive module. The clutch assembly includes a first clutch shaft, a second clutch shaft, and a second spring. The first clutch shaft is movably disposed on the first rotating shaft. The second spring applies an elastic force to the first clutch shaft to cause the first clutch shaft to abut against the second clutch shaft. The lever is sleeved on the first clutch shaft. The in-door drive module includes a second rotating shaft and an inner knob. The second rotating shaft is disposed inside the lock housing and is throttle-connected to the second clutch shaft. The inner knob is located at the end of the lock housing away from the out-of-door drive module and is connected to the second rotating shaft. Pressing the inner knob causes the second rotating shaft and the second clutch shaft to drive the first clutch shaft to compress the second spring. The lever is sleeved on the second clutch shaft.

[0024] Specifically, when no external force is applied to the inward drive module, the second spring provides elastic force to the first clutch shaft, causing the first clutch shaft to abut against the second clutch shaft. The lever is sleeved on the first clutch shaft, so that when the electronic lock cylinder is in the unlocked position and connected to the first rotating shaft, the outer knob can rotate the electronic lock cylinder, the first rotating shaft, and the first clutch shaft in sequence, thereby rotating the lever. At the same time, the first clutch shaft rotates relative to the second clutch shaft, so that the inward drive module does not rotate relative to the outward drive module. When an external force is applied to the inward drive module in the direction of the electronic lock head centerline, the second rotating shaft drives the second clutch shaft to disengage the first clutch shaft from the lever, and the lever is sleeved outside the second clutch shaft. This allows the inner knob to rotate the lever by driving the second rotating shaft and the second clutch shaft. At the same time, the second clutch shaft rotates relative to the first clutch shaft, so that the outward drive module does not rotate relative to the inward drive module.

[0025] In the above technical solution, by setting a clutch component, on the one hand, the rotation of the external drive module and the internal drive module is made independent of each other, so as to reduce the risk of damage to the electronic lock head caused by the simultaneous rotation of the external drive module and the internal drive module. On the other hand, it is convenient for the external drive module and the internal drive module to connect and disconnect from the toggle transmission. The structure is simple and easy to implement.

[0026] In some embodiments, the inner circumferential surface of the paddle is provided with a limiting groove, the outer circumferential surface of the first clutch shaft is provided with a second limiting protrusion that cooperates with the limiting groove, and the outer circumferential surface of the second clutch shaft is provided with a third limiting protrusion that cooperates with the limiting groove.

[0027] In the above technical solution, by providing a limiting groove on the inner circumferential surface of the clutch block and a second limiting protrusion that mates with the limiting groove on the outer circumferential surface of the first clutch shaft, the clutch block can be rotated by the engagement of the second limiting protrusion and the limiting groove when the first clutch shaft is inserted into the clutch block. At the same time, a third limiting protrusion that mates with the limiting groove is provided on the outer circumferential surface of the second clutch shaft, so that the clutch block can be rotated by the engagement of the third limiting protrusion and the limiting groove when the second clutch shaft is inserted into the clutch block. The structure is simple and easy to implement. Attached Figure Description

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0044] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0045] In this application, "multiple" means two or more (including two).

[0046] Existing electronic locks typically use a drive module to move a transmission mechanism, which in turn drives the clutch to switch between the unlock and lock positions. When the drive module moves the transmission mechanism, it is easy for it to rotate too many times. This can cause the drive module to continue rotating the transmission mechanism after the clutch has rotated to the lock or unlock position, leading to the drive module stalling. This, in turn, increases the current flowing through the drive module, thereby increasing the risk of damage to the drive module.

[0047] Based on the above considerations, in order to reduce the probability of drive module stalling and thus reduce the risk of drive module damage, this application provides an electronic lock cylinder, including a housing, a circuit control module, a Type-C male connector, a drive module, a transmission rod, a locking block, and a first spring. The circuit control module, Type-C male connector, drive module, and transmission rod are disposed within the housing; one end of the Type-C male connector extends out of the housing, and the other end is connected to the circuit control module; the drive module is connected to the transmission rod; the locking block is movably sleeved on the transmission rod, and the locking block has an unlocked position extending out of the housing and a locked position retracted into the housing, with a receiving cavity formed inside the locking block; the first spring is disposed within the receiving cavity and sleeved on the transmission rod, and a first limiting protrusion is provided on the outer circumferential surface of the transmission rod, the first limiting protrusion passing between two turns of the first spring's spiral; the drive module drives the transmission rod to rotate forward and backward, so that the transmission rod, through the first spring, pushes the locking block to the locked and unlocked positions.

[0048] In this type of electronic lock cylinder, the first spring is sleeved on the transmission rod and located within the receiving cavity. Simultaneously, the first limiting protrusion passes between the two turns of the first spring's spiral. Therefore, when the first limiting protrusion rotates with the transmission rod, it moves along the spiral of the first spring, causing the first spring to move along the transmission rod and abut against the two walls of the receiving cavity in its direction of movement. This allows the first spring to provide elastic force to the receiving cavity, thereby switching the locking block between the locked and unlocked positions. Specifically, taking an external device (such as a mobile phone) as an example, power is supplied to the drive module via a Type-C male connector, causing the drive module to switch the locking block from the unlocked position to the locked position. In the unlocked position, the portion of the first spring located between the wall of the accommodating cavity near the unlocked position and the first limiting protrusion reaches its maximum length in the spring's extension direction. This allows the portion of the first spring to apply an elastic force to the wall of the accommodating cavity near the unlocked position, thus keeping the locking block in the unlocked position. When switching the locking block from the unlocked position to the locked position, the drive module drives the transmission rod to rotate forward, causing the length of the portion of the first spring located between the wall of the accommodating cavity near the unlocked position and the first limiting protrusion in the spring's extension direction to gradually decrease, and causing the length of the portion of the first spring located between the wall of the accommodating cavity near the locked position and the first limiting protrusion in the spring's extension direction to gradually increase. This, on the one hand, causes the portion of the first spring located between the wall of the accommodating cavity near the unlocked position and the first limiting protrusion to lift the portion of the first spring located between the wall of the accommodating cavity near the unlocked position towards the wall of the accommodating cavity near the unlocked position. The supplied elastic force gradually decreases. On the other hand, the portion of the first spring located between the wall of the accommodating cavity near the locking position and the first limiting protrusion provides a gradually increasing elastic force to the wall of the accommodating cavity near the locking position, thereby driving the locking block to switch from the unlocked position to the locked position. When the locking block switches to the locked position and the drive module tends to continue rotating, the transmission rod continues to rotate in the forward direction, so that the first limiting protrusion continues to move along the extension direction of the first spring. This causes the length of the portion of the first spring located between the wall of the accommodating cavity near the locking position and the first limiting protrusion in the extension direction of the first spring to further increase, so as to provide a greater elastic force to the wall of the accommodating cavity near the locking position, until the first spring is completely located between the wall of the accommodating cavity near the locking position and the first limiting protrusion. At this time, the first limiting protrusion and the spiral abutment of the end of the first spring away from the locking position are engaged. Thus, when the transmission rod rotates in the forward direction to drive the first limiting protrusion to rotate, the spiral abutment of the first limiting protrusion and the end of the first spring away from the locking position is engaged in a reciprocating cycle. This allows the drive module to continue rotating. Therefore, when the locking block switches to the locked or unlocked position and the drive module tends to continue rotating, the drive module can continue to rotate, reducing the probability of the drive module stalling and thus reducing the risk of damage to the drive module.

[0049] The electronic lock cylinder is described in detail below with reference to the accompanying drawings.

[0050] Please refer to Figure 1 and Figure 2 Please refer to Figure 3 , Figure 1 This is a structural cross-sectional view of the electronic lock cylinder 100 in the unlocked position according to some embodiments of this application. Figure 2 This is a structural cross-sectional view of the electronic lock cylinder 100 in the locked position according to some embodiments of this application. Figure 3 This is an exploded view of the structure of an electronic lock cylinder 100 provided in some embodiments of this application. Embodiments of this application provide an electronic lock cylinder 100, including a housing 10, a circuit control module 20, a Type-C male connector 30, a drive module 40, a transmission rod 50, a locking block 60, and a first spring 70. The circuit control module 20 is disposed within the housing 10; one end of the Type-C male connector 30 extends out of the housing 10, and the other end is connected to the circuit control module 20; the drive module 40 is disposed within the housing 10; the transmission rod 50 is disposed within the housing 10 and is drively connected to the drive module 40; the locking block 60 is movably sleeved on the transmission rod 50, and the locking block 60 has an unlocked position extending out of the housing 10 and a locked position retracted into the housing 10, with a receiving cavity 621 formed inside the locking block 60; the first spring 70... The locking block 60 is set inside the accommodating cavity 621 and sleeved on the transmission rod 50. The outer circumferential surface of the transmission rod 50 is provided with a first limiting protrusion 51, which passes between the two turns of the first spring 70. When the driving module 40 drives the transmission rod 50 to rotate in the forward direction, the transmission rod 50 can push the locking block 60 to the locked position through the first spring 70. When the driving module 40 drives the transmission rod 50 to rotate in the reverse direction, the transmission rod 50 can push the locking block 60 to the unlocked position through the first spring 70.

[0051] The outer casing 10 is a shell-like structure in the electronic lock cylinder 100 used to house other mechanical components. Exemplarily, the outer casing 10 can be made of metal, plastic, or ceramic.

[0052] In some embodiments, the housing 10 includes a first housing 11 and a second housing 12, which are fastened together to form a cavity for accommodating the drive module 40, the transmission rod 50, and the circuit control module 20.

[0053] The first housing 11 and the second housing 12 are the two main body parts of the outer casing 10. Exemplarily, the first housing 11 and the second housing 12 are detachably connected.

[0054] Understandably, by setting the outer casing 10 as a split first casing 11 and second casing 12, on the one hand, the processing difficulty of the outer casing 10 is reduced, which is conducive to reducing the manufacturing cost of the electronic lock cylinder 100; on the other hand, it is convenient to set other structural components (such as circuit control module 20, Type-C male connector 30, drive module 40, transmission rod 50, locking block 60 and first spring 70) inside the outer casing 10, thereby simplifying the assembly difficulty of the electronic lock cylinder 100.

[0055] The circuit control module 20 is structured to identify external devices and electrically connect the Type-C male connector 30 and the drive module 40.

[0056] The Type-C male 30 (Type-C Plug) is the plug part of the USB Type-C interface. It is the end that is inserted into the connector and is used to mate with the Type-C female connector on an external device.

[0057] For example, the external device can be a mobile phone or a Bluetooth electronic key.

[0058] In some embodiments, the external device is a mobile phone. The mobile phone is directly inserted into the Type-C male connector 30. After authorization by the mobile phone APP, communication is matched, power is supplied to the drive module 40, and the electronic lock cylinder 100 is unlocked.

[0059] In some embodiments, the external device is a Bluetooth electronic key. The Bluetooth electronic key is inserted into the Type-C male connector 30. The Bluetooth electronic key has unlocking permissions that match the circuit control module 20 of the electronic lock cylinder 100. Communication is matched, power is supplied to the drive module 40, and the electronic lock cylinder 100 is unlocked.

[0060] In some embodiments, the external device is a Bluetooth electronic key. The Bluetooth electronic key is inserted into the Type-C male connector 30 and connects to a mobile APP via Bluetooth. After authorization by the mobile APP, the Bluetooth electronic key supplies power to the drive module 40 to unlock the electronic lock cylinder 100.

[0061] The drive module 40 can be a component that drives the transmission rod 50 to rotate. For example, the drive module 40 can be a solenoid or a motor. It is understood that the drive module 40 can directly drive the transmission rod 50 to rotate, or the drive module 40 can indirectly drive the transmission rod 50 to rotate through a transmission mechanism.

[0062] The locking block 60 is a structure that is movably mounted on the transmission rod 50. For example, the locking block 60 has a first through hole 601 that extends through the locking block 60 along the axial direction of the transmission rod 50, and the transmission rod 50 is inserted into the first through hole 601.

[0063] The first limiting protrusion 51 is a protruding structure that protrudes from the side of the transmission rod 50.

[0064] In some embodiments, the transmission rod 50 has a positioning hole that extends radially through the transmission rod 50, and a positioning pin is inserted into the positioning hole. The two ends of the positioning pin protrude from the periphery of the transmission rod 50 to form a first limiting protrusion 51.

[0065] Understandably, the two ends of the first spring 70 are configured to move along the axis of the accommodating cavity 621.

[0066] Specifically, an external device (such as a mobile phone) supplies power to the drive module 40 via a Type-C male connector 30, causing the module to drive the locking block 60 to switch from the unlocked position to the locked position. In the unlocked position, the portion of the first spring 70 located between the wall of the accommodating cavity 621 near the unlocked position and the first limiting protrusion 51 reaches its maximum length in the extending direction of the first spring 70. This portion of the first spring 70 applies an elastic force to the wall of the accommodating cavity 621 near the unlocked position, keeping the locking block 60 in the unlocked position. When the locking block 60 is switched from the unlocked position to the locked position... At this time, the drive module 40 drives the transmission rod 50 to rotate forward, so that the length of the portion of the first spring 70 located between the wall of the accommodating cavity 621 near the unlocked position and the first limiting protrusion 51 in the extending direction of the first spring 70 gradually decreases, and the length of the portion of the first spring 70 located between the wall of the accommodating cavity 621 near the locked position and the first limiting protrusion 51 in the extending direction of the first spring 70 gradually increases. On the one hand, this causes the portion of the first spring 70 located between the wall of the accommodating cavity 621 near the unlocked position and the first limiting protrusion 51 to move towards the wall of the accommodating cavity 621 near the unlocked position. The provided elastic force gradually decreases. On the other hand, the portion of the first spring 70 located between the wall of the accommodating cavity 621 near the locked position and the first limiting protrusion 51 provides a gradually increasing elastic force to the wall of the accommodating cavity 621 near the locked position, thereby driving the locking block 60 to switch from the unlocked position to the locked position. When the locking block 60 switches to the locked position and the drive module 40 tends to continue rotating, the transmission rod 50 continues to rotate in the forward direction, so that the first limiting protrusion 51 continues to move along the extension direction of the first spring 70, thereby keeping the first spring 70 located near the locked position of the accommodating cavity 621. The portion between the wall portion and the first limiting protrusion 51 further increases in length in the extending direction of the first spring 70 to provide greater elastic force to the wall portion of the accommodating cavity 621 near the locking position, until the first spring 70 is completely located between the wall portion of the accommodating cavity 621 near the locking position and the first limiting protrusion 51. At this point, the first limiting protrusion 51 and the end of the first spring 70 away from the locking position are in helical contact. As the transmission rod 50 rotates in the forward direction to drive the first limiting protrusion 51 to rotate, the first limiting protrusion and the end of the first spring 70 away from the locking position repeatedly engage in helical contact. This allows the drive module 40 to continue rotating.

[0067] In this embodiment, when the locking block 60 switches to the locked or unlocked position and the drive module 40 tends to continue rotating, the drive module 40 can continue to rotate, reducing the probability of the drive module 40 stalling and thus reducing the risk of damage to the drive module 40.

[0068] Please refer to Figure 1 and Figure 2According to some embodiments of this application, the locking block 60 may include a body 62 and a protrusion 61. The protrusion 61 protrudes from one end of the body 62. When in the unlocked position, a portion of the protrusion 61 protrudes from the second through hole 101 on the housing 10 to be located outside the housing 10. When in the unlocked position, a portion of the protrusion 61 is located inside the second through hole 101 on the housing 10.

[0069] In some embodiments, the outer peripheral side of the body 62 protrudes from the outer peripheral side of the protrusion 61 to form a stepped surface on the outer periphery of the locking block 60. The stepped surface is used to abut against the inner surface of the wall portion of the housing 10 where the second through hole 101 is provided, so as to restrict the locking block 60 from disengaging from the housing 10.

[0070] In some embodiments, an isolation portion 102 is provided on the periphery of the housing 10. The driven gear 82 and the locking block 60 are respectively located on opposite sides of the isolation portion 102 in the axial direction of the housing 10. When the locking block 60 is in the locked position, the isolation portion 102 abuts against the body 62 of the locking block 60 to reduce the risk of the locking block 60 interfering with the rotation of the driven gear 82 and to limit the range of motion of the locking block 60.

[0071] In this embodiment, the stepped surface abuts against the inner surface of the wall portion of the outer shell 10 where the second through hole 101 is provided, thereby restricting the locking block 60 from disengaging from the outer shell 10 and limiting the range of motion of the locking block 60, thus improving the reliability of the lock cylinder unlocking and locking. The structure is simple and easy to implement.

[0072] According to some embodiments of this application, the cavity wall of the accommodating cavity 621 is provided with a limiting groove 622 extending axially along the transmission rod 50; the two ends of the first spring 70 are provided with limiting portions 71, and both limiting portions 71 are inserted into the limiting groove 622.

[0073] In some embodiments, a limiting groove 622 is provided around the body 62, the limiting groove 622 extends along the axial direction of the body 62, and limiting portions 71 are provided at opposite ends of the first spring 70. Both limiting portions 71 are inserted into the limiting groove 622 to restrict the rotation of the first elastic member relative to the locking block 60.

[0074] Since the first spring 70 is sleeved on the transmission rod 50 and located within the accommodating cavity 621, and the first limiting protrusion 51 passes between the two spiral turns of the first spring 70, when the first limiting protrusion 51 rotates with the transmission rod 50, the first limiting protrusion 51 will move along the spiral of the first spring 70, thereby causing the first spring 70 to move along the transmission rod 50 and abut against the two walls of the accommodating cavity 621 in its direction of movement. This allows the first spring 70 to provide elastic force to the accommodating cavity 621, thereby driving the locking block 60 to switch between the locked and unlocked positions.

[0075] In this embodiment, by inserting both limiting parts 71 into the limiting groove 622, the first spring 70 can move along the axial direction of the transmission rod 50 while the rotation of the first spring 70 relative to the locking block 60 is restricted. The structure is simple and easy to implement.

[0076] Please refer to Figures 1-3 According to some embodiments of this application, the Type-C male connector 30 and the locking block 60 are located at opposite ends of the housing 10 in its axial direction; the drive module 40 and the transmission rod 50 are arranged radially along the housing 10.

[0077] For example, the Type-C male connector 30 extends from one end of the housing 10 in the axial direction, and when the locking block 60 is in the unlocked position, the locking block 60 extends from the other end of the housing 10 in the axial direction.

[0078] In some embodiments, the drive module 40 and the transmission rod 50 are arranged radially along the housing 10. The electronic lock core 100 also includes a transmission belt, which is sleeved on the output shaft of the drive module 40 and the transmission rod 50. The drive module 40 and the transmission rod 50 are connected by the transmission belt.

[0079] In some embodiments, the drive module 40 and the transmission rod 50 are arranged radially along the housing 10. The electronic lock core 100 also includes a first sprocket, a second sprocket, and a chain. The first sprocket is mounted on the output shaft of the drive module 40, the second sprocket is mounted on the transmission rod 50, and the chain is sleeved on the first sprocket and the second sprocket. The drive module 40 and the transmission rod 50 are connected by the first sprocket, the second sprocket, and the chain. The first sprocket is mounted on the output shaft of the drive module 40, and the second chain is connected by a drive.

[0080] In this embodiment, the Type-C male connector 30 and the locking block 60 are located at opposite ends of the housing 10 in its axial direction, so as to reduce the risk of the Type-C male connector 30 interfering with the movement of the locking block 60 when the locking block 60 switches between the locked and unlocked positions; at the same time, the drive module 40 and the transmission rod 50 are arranged radially, so that the drive module 40 and the transmission rod 50 jointly occupy part of the space of the housing 10 in its axial direction, thereby reducing the size of the housing 10 in its axial direction compared with the case where the drive module 40 and the transmission rod 50 are arranged in the axial direction of the housing 10, which is beneficial to reducing the size of the electronic lock cylinder 100 in its axial direction.

[0081] Please refer to Figures 1-3 According to some embodiments of this application, the drive module 40 further includes a motor 41, a drive gear 81, and a driven gear 82; the drive gear 81 is mounted on the output shaft of the drive module 40; the driven gear 82 is mounted on the transmission rod 50 and meshes with the drive gear 81.

[0082] In some embodiments, the electronic lock cylinder 100 further includes a bracket 90 disposed within the housing 10 to divide the interior of the housing 10 into a first cavity 103 and a second cavity 104 arranged radially along the housing 10. The drive module 40 is located within the first cavity 103, and the transmission rod 50 is located within the second cavity 104.

[0083] The bracket 90 is a structure in the electronic lock core 100 used to divide the interior of the outer shell 10 into two cavities: a first cavity 103 and a second cavity 104. Understandably, the first cavity 103 and the second cavity 104 can be connected to each other or isolated from each other by the bracket 90.

[0084] Understandably, the bracket 90 divides the interior of the outer casing 10 into a first cavity 103 and a second cavity 104 arranged radially, and the drive module 40 and the transmission rod 50 are respectively disposed in the first cavity 103 and the second cavity 104, so as to reduce the risk of mutual interference between the drive module 40 and the transmission rod 50 and improve the reliability of the electronic lock cylinder 100.

[0085] In some embodiments, the bracket 90 is connected to the first housing 11 and the second housing 12 on both sides of the outer casing 10 in the radial direction, respectively, to increase the stability of the connection between the first housing 11 and the second housing 12.

[0086] In this embodiment, by setting a driving gear 81 and a driven gear 82, and by meshing the driving gear 81 and the driven gear 82 to drive the transmission rod 50 to rotate, the drive module 40 drives the transmission rod 50 to rotate. On the one hand, compared with chain drive and belt drive, no additional tensioning space is required, which makes the internal structure of the electronic lock core 100 more compact and reduces the space occupied by the transmission mechanism between the drive module 40 and the transmission rod 50 in the housing 10, which is beneficial to reducing the volume of the housing 10. On the other hand, the drive module 40 and the transmission rod 50 are arranged radially along the housing 10, and the output shaft of the drive module 40 drives the transmission rod 50 to rotate in the forward or reverse direction, which is simple and easy to implement.

[0087] According to some embodiments of this application, motor 41 is a coreless motor.

[0088] A coreless motor is a specially designed DC permanent magnet servo micro motor. Its core innovation lies in the use of a coreless rotor (the rotor has a hollow cup-shaped structure), which significantly outperforms traditional iron-core motors in terms of efficiency, response speed, and lightweight design.

[0089] In this embodiment, the hollow cup motor eliminates the traditional silicon steel sheet stacking structure through the coreless rotor design, and the rotor consists only of cup-shaped windings and commutators, eliminating the need for iron core support components. As a result, it is smaller in size than the traditional motor, thereby reducing the space occupied inside the housing 10, which is beneficial to reducing the volume of the housing 10, and thus the volume of the electronic lock cylinder 100.

[0090] Please refer to Figure 4 Please refer to Figure 5 and Figure 6 , Figure 4 This is a schematic diagram of the structure of the electronic lock 10000 provided in some embodiments of this application. Figure 5 This is a structural cross-sectional view of the electronic lock cylinder 10000 when the locking block 60 is in the unlocked position, according to some embodiments of this application. Figure 6 This is a cross-sectional view of the electronic lock cylinder 10000 when the locking block 60 is in the locked position according to some embodiments of this application. Embodiments of this application also provide an electronic lock cylinder 10000, including a lock housing 2000, a lever 3000, and an external drive module 1000; the external drive module 1000 includes an external knob 200, a first rotating shaft 300, and an electronic lock cylinder 100 as described in any of the above embodiments. The electronic lock cylinder 100 and the first rotating shaft 300 are disposed within the lock housing 2000. The first rotating shaft 300 has a groove 310 that mates with the locking block, and the groove 310 is offset from the central axis of the first rotating shaft 300. The external knob 200 is located at one end of the lock housing 2000 and connected to the outer housing 10; the lever 3000 is connected to the first rotating shaft 300; when the locking block 60 is in the unlocked position, the locking block 60 enters the groove 310, and the rotation of the electronic lock cylinder 100 can drive the first rotating shaft 300 to rotate, thereby driving the lever 300 to rotate; when the locking block 60 is in the locked position, the locking block 60 exits the groove 310, and the electronic lock cylinder 100 can rotate freely relative to the first rotating shaft 300.

[0091] The lock housing 2000 is a structural component in the electronic lock cylinder 10000 used to accommodate other structural components or to provide mounting positions for other structural components.

[0092] The lever 3000 is configured to rotate relative to the lock housing 2000 so as to disengage the bolt connected to the lever 3000 from the slot on the door frame, etc., thereby unlocking the lock with the electronic lock cylinder 10000.

[0093] The external drive module 1000 is a drive module 40 installed outside the door to drive the toggle block 3000 to rotate and unlock the lock.

[0094] The first rotating shaft 300 is a rotating shaft that is connected to the lever 3000 in a transmission manner. It can be understood that the first rotating shaft 300 can be directly connected to the lever 3000, or it can be indirectly connected to the lever 3000 through a transmission structure.

[0095] The groove 310 is a groove-shaped structure located at the end of the first rotating shaft 300 facing the electronic lock cylinder 100.

[0096] Understandably, the rotation axis of the first rotating shaft 300, the rotation axis of the electronic lock cylinder 100, and the rotation axis of the toggle block 3000 are collinear with the center line. Thus, when the locking block 60 is in the unlocked position and the electronic lock cylinder 100 rotates, the portion of the locking block 60 located in the groove 310 can rotate around the rotation axis of the first rotating shaft 300, thereby driving the first rotating shaft 300 to rotate.

[0097] The external knob 200 is a structural component of the external drive module 1000 that is partially exposed outside the door. It can be understood that the external knob 200 is used to facilitate the operator to rotate the electronic lock cylinder 100, thereby driving the first rotating shaft 300 to rotate.

[0098] In some embodiments, the external knob 200 includes a mounting sleeve 210 and a post 220. The mounting sleeve 210 is fitted around the periphery of the housing 10, and the post 220 is located at the end of the mounting sleeve 210 away from the toggle block 3000 and extends along the centerline direction to be located on the side of the Type-C male connector 30, so as to reduce the risk of the Type-C male connector 30 being damaged by collision with external structures.

[0099] In some embodiments, the posts 220 are two respectively arranged on opposite sides of the Type-C male connector 30 in the width direction, thereby enabling the posts 220 to avoid external devices and further reduce the risk of the Type-C male connector 30 being damaged by collisions with external structures.

[0100] Specifically, when unlocking and locking the electronic lock cylinder 10000, an external device (such as a mobile phone) supplies power to the drive module 40 via the Type-C male connector 30. The drive module 40 then drives the transmission rod 50 to rotate in the opposite direction, which in turn pushes the locking block 60 to the unlocked position via the first spring 70. This causes the locking block 60 to enter the groove 310. At this time, the external knob 200 applies external force to the electronic lock cylinder 100, causing it to rotate. This, in turn, causes the first rotating shaft 300 to rotate, which in turn causes the toggle block 3000 to rotate, thus enabling the electronic lock cylinder 10000 to be in both the unlocked and locked states. Switching between lock states: When there is no need to unlock the electronic lock cylinder 10000, an external device (such as a mobile phone) provides power to the drive module 40 through the Type-C male connector 30, so that the drive module 40 drives the transmission rod 50 to rotate in the forward direction, so that the first spring 70 pushes the locking block 60 to move to the locked position. The locking block 60 exits the groove 310, and the electronic lock cylinder 100 can rotate freely relative to the first rotating shaft 300, so that when the external knob 200 drives the electronic lock cylinder 100 to rotate, it no longer drives the toggle block 3000 to rotate, thus fixing the electronic lock cylinder 10000 in the unlocked or locked state.

[0101] In this embodiment, the drive module 40 drives the transmission rod 50 to rotate, so that the transmission rod 50 drives the locking block 60 to be in the unlocked or locked position, so that the outer knob 200 can drive the lever 3000 to rotate, or cannot drive the lever 3000 to rotate. On the one hand, compared with the case where the drive module 40 directly drives the lever 3000 to rotate, the torque required by the drive module 40 is reduced, which is conducive to using a drive module 40 with less power, and thus conducive to reducing the size of the drive module 40. On the other hand, the first aspect provides that the electronic lock cylinder 100 controls the transmission connection and disengagement between the outer knob 200 and the lever 3000, which is simple in structure and easy to implement.

[0102] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the electronic lock cylinder 10000 after the dust cover 400 is installed according to some embodiments of this application. According to some embodiments of this application, the door drive module 1000 also includes a dust cover 400; the dust cover 400 is detachably sleeved on the end of the outer knob 200 away from the electronic lock cylinder 100, and the Type-C male connector 30 is located inside the dust cover 400.

[0103] The dust cover 400 is a cap-like structure placed on the outside of the Type-C male connector 30 to prevent dust from falling in.

[0104] For example, the dust cover 400 can be connected to the end of the external knob 200 away from the electronic lock cylinder 100 by means of bolt connection, snap-fit, etc.

[0105] In some embodiments, a magnetic element 230 is installed at the end of the outer knob 200 away from the electronic lock cylinder 100, and at least a portion of the dust cover 400 is made of a ferromagnetic material so that the dust cover 400 can be attracted to the end of the outer knob 200 away from the electronic lock cylinder 100.

[0106] In this embodiment, the Type-C male connector 30 is located inside the dust cover 400 so that when not in use, the dust cover 400 can reduce the risk of external dust falling on the Type-C male connector 30. At the same time, since the dust cover 400 is detachably fitted onto the end of the outer knob 200 away from the door drive module 5000, the risk of the dust cover 400 interfering with the connection between external devices and the Type-C male connector 30 is reduced.

[0107] Please refer to Figure 5 and Figure 6 Please refer to Figure 8 and Figure 9 , Figure 8 for Figure 6 A magnified view of a portion of point A in the middle. Figure 9 for Figure 5A partial enlarged view at point B. According to some embodiments of this application, the electronic lock cylinder 10000 further includes a clutch assembly 4000 and an in-door drive module 5000. The clutch assembly 4000 is disposed between the in-door drive module 5000 and the out-of-door drive module 1000. The clutch assembly 4000 includes a first clutch shaft 4100, a second clutch shaft 4200, and a second spring 4300. The first clutch shaft 4100 is movably disposed on a first rotating shaft 300. The second spring 4300 is used to apply an elastic force to the first clutch shaft 4100 so that the first clutch shaft 4100 abuts against the second clutch shaft 4200. The lever 30... The door drive module 5000 includes a second rotating shaft 5100 and an inner knob 5200. The second rotating shaft 5100 is located inside the lock housing 2000 and is connected to the second clutch shaft 4200. The inner knob 5200 is located at the end of the lock housing 2000 away from the door drive module 1000 and is connected to the second rotating shaft 5100. Pressing the inner knob 5200 causes the second rotating shaft 5100 and the second clutch shaft 4200 to drive the first clutch shaft 4100 to compress the second spring 4300. The toggle block 3000 is sleeved on the second clutch shaft 4200.

[0108] The first clutch shaft 4100 and the second clutch shaft 4200 are two clutch shafts in the clutch assembly 4000 that are respectively connected to the first rotating shaft 300 and the second rotating shaft 5100. Understandably, when the first clutch shaft 4100 is located inside the shift block 3000, the first clutch shaft 4100 can be driven to rotate the shift block 3000. The second clutch shaft 4200 can be driven to rotate the shift block 3000.

[0109] In some embodiments, please refer to Figure 8 One end of the first rotating shaft 300 is sleeved outside the first clutch shaft 4100. The outer periphery of the first clutch shaft 4100 is provided with a second limiting protrusion 4110. The inner periphery of the first rotating shaft 300 is provided with a first guide groove 320, which extends along the center line. The second limiting protrusion 4110 is located inside the first guide groove 320. When the first rotating shaft 300 rotates, the groove wall of the first guide groove 320 can drive the second limiting protrusion 4110 to drive the first clutch shaft 4100 to rotate. The second spring 4300 is located inside the first rotating shaft 300.

[0110] Understandably, along the centerline direction, the first pivot 300 is fixed relative to the lock housing 2000.

[0111] In some embodiments, please refer to Figure 9The door drive module 5000 also includes a third rotating shaft 5300. One end of the third rotating shaft 5300 is sleeved outside the second rotating shaft 5100. The outer periphery of the second clutch shaft 4200 is provided with a third limiting protrusion 4210, and the inner periphery of the third rotating shaft 5300 is provided with a second guide groove 5310. The second guide groove 5310 extends along the center line direction, and the third limiting protrusion 4210 is located inside the second guide groove 5310. When the second rotating shaft 5100 rotates, it can drive the third rotating shaft 5300 to rotate, so that the groove wall of the second guide groove 5310 can drive the third limiting protrusion 4210 to drive the second clutch shaft 4200 to rotate.

[0112] In some embodiments, the second rotating shaft 5100 is provided with a mounting hole extending radially therein, and a pin 5110 is provided in the mounting hole. One end of the pin 5110 protrudes from the outer periphery of the second rotating shaft 5100 and is located in the second guide groove 5310. The pin 5110 abuts against the groove wall of the second guide groove 5310 along the center line direction to prevent the second rotating shaft 5100 from dislodging from the third rotating shaft 5300.

[0113] Understandably, along the centerline direction, the third pivot 5300 is fixed relative to the lock housing 2000.

[0114] Specifically, without applying external force to the door drive module 5000, the second spring 4300 provides elastic force to the first clutch shaft 4100, causing the first clutch shaft 4100 to abut against the second clutch shaft 4200. The toggle block 3000 is sleeved on the first clutch shaft 4100. Thus, when the electronic lock cylinder 100 is in the unlocked position and connected to the first rotating shaft 300, the outer knob 200 can sequentially rotate the electronic lock cylinder 100, the first rotating shaft 300, and the first clutch shaft 4100, thereby rotating the toggle block 3000. Simultaneously, the first clutch shaft 4100 rotates relative to the second clutch shaft 4200, causing the door drive module 5000 to rotate. The door drive module 1000 does not rotate relative to the external drive module 1000. When an external force is applied to the internal drive module 5000 in the direction of the center line of the electronic lock head 10000, the second rotating shaft 5100 drives the second clutch shaft 4200 to drive the first clutch shaft 4100 to disengage from the lever 3000, and the lever 3000 is sleeved on the outside of the second clutch shaft 4200, so that the inner knob 5200 drives the second rotating shaft 5100 and the second clutch shaft 4200 to drive the lever 3000 to rotate. At the same time, the second clutch shaft 4200 rotates relative to the first clutch shaft 4100, so that the external drive module 1000 does not rotate relative to the internal drive module 5000.

[0115] In this embodiment, by setting the clutch assembly 4000, on the one hand, the rotation of the external drive module 1000 and the internal drive module 5000 is made independent of each other, so as to reduce the risk of damage to the electronic lock head 10000 caused by the simultaneous rotation of the external drive module 1000 and the internal drive module 5000. On the other hand, it facilitates the transmission connection and disengagement of the external drive module 1000 and the internal drive module 5000 with the toggle block 3000. The structure is simple and easy to implement.

[0116] Please refer to Figure 5 and Figure 6 According to some embodiments of this application, the inner peripheral surface of the clutch block 3000 is provided with a limiting groove 3100, the outer peripheral surface of the first clutch shaft 4100 is provided with a second limiting protrusion 4110 that cooperates with the limiting groove 3100, and the outer peripheral surface of the second clutch shaft 4200 is provided with a third limiting protrusion 4210 that cooperates with the limiting groove 3100.

[0117] In this embodiment, a limiting groove 3100 is provided on the inner circumferential surface of the clutch block 3000, and a second limiting protrusion 4110 that cooperates with the limiting groove 3100 is provided on the outer circumferential surface of the first clutch shaft 4100. When the first clutch shaft 4100 is inserted into the clutch block 3000, the clutch block 3000 can be rotated by the cooperation of the second limiting protrusion 4110 and the limiting groove 3100. At the same time, a third limiting protrusion 4210 that cooperates with the limiting groove 3100 is provided on the outer circumferential surface of the second clutch shaft 4200. When the second clutch shaft 4200 is inserted into the clutch block 3000, the clutch block 3000 can be rotated by the cooperation of the third limiting protrusion 4210 and the limiting groove 3100. The structure is simple and easy to implement.

[0118] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.
