Description

Technical Field

[0001] This utility model belongs to the field of door lock technology, specifically relating to intelligent lock cylinders. Background Technology

[0002] Currently, entrance doors with smart locks typically consist of three parts: the door leaf, the lock body, and the smart lock itself. For entrance doors using standard lock bodies, smart locks require at least four components: a front panel, connectors, transmission components, and a rear panel. Some doors with fully automatic locking and unlocking functions also require a dedicated electric lock body. The front and rear panels of the smart lock need to be securely fixed to the door leaf using connectors, and a complex electrical connection is usually required between them, involving wiring across the door leaf. Some smart locks even require the battery module to be installed inside the door leaf. This complex structure presents several problems. Firstly, existing smart locks have compatibility issues and poor adaptability to different door leaves. For doors that are thin or where drilling to install connectors is inconvenient, it is difficult to install smart locks, limiting their widespread adoption. On the other hand, currently, smart locks all use batteries or external power as the main power source. However, battery power has many drawbacks. Once the internal battery is depleted, users must use a power bank or other means to provide emergency power, otherwise they will not be able to open the door, causing great inconvenience to users. Regularly replacing or charging the internal batteries also increases maintenance costs. Furthermore, the discarded batteries may cause environmental pollution. In addition, battery performance is greatly affected by ambient temperature. In excessively hot or cold regions, the battery's endurance and stability will decrease, thus affecting the function of the smart lock. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides an intelligent lock cylinder to solve problems such as the complex structure, inconvenient installation, need for regular battery replacement or charging, and poor compatibility with door panels and lock bodies of existing intelligent locks. With its identical physical dimensions to existing mechanical lock cylinders for entry doors and its advanced electromechanical coupling design, this utility model can easily upgrade mechanical locks to intelligent locks, improving the security, convenience, and environmental friendliness of door locks, and providing users with a superior user experience.

[0004] The technical solution adopted by this utility model to solve the aforementioned problems is as follows:

[0005] A smart lock cylinder includes: a lock cylinder body; a first lock cylinder shaft rotatably disposed on the lock cylinder body, with a connecting groove at its second end; a second lock cylinder shaft rotatably disposed on the lock cylinder body, with its first end slidably disposed in the connecting groove; an actuating member connected to the second lock cylinder shaft, the actuating member and the second lock cylinder shaft rotating synchronously, the actuating member being used for transmission connection with the lock tongue; a transmission member movably disposed in the connecting groove; and a driving member disposed on the lock cylinder body, the driving member being used to drive the second lock cylinder shaft to move axially from a first position to a second position relative to the actuating member when activated; when the second lock cylinder shaft is in the first position, the transmission member and the actuating member separate, and the first lock cylinder shaft... When rotating, the actuating member remains stationary; when the second lock cylinder shaft is in the second position, the first end of the second lock cylinder shaft pushes against the transmission member and pushes the transmission member to partially protrude from the connecting groove, so that the transmission member and the actuating member are engaged. The rotation of the first lock cylinder shaft can drive the actuating member to rotate synchronously through the transmission member; the smart lock cylinder also includes a generator and a circuit board, both disposed on the lock cylinder body. The first lock cylinder shaft and the rotating shaft of the generator are connected by a drive connection. The generator is electrically connected to the circuit board and the driving member respectively; when the first lock cylinder shaft rotates, it can drive the generator to generate electricity to supply power to the circuit board and the driving member. When the circuit board is energized, it can generate a control signal to control the start and stop of the driving member.

[0006] As an optional implementation, the connecting groove includes a first connecting groove extending axially and a second connecting groove extending radially, the first connecting groove and the second connecting groove are connected, the first end of the second lock cylinder is disposed in the first connecting groove, and the transmission member is movably disposed in the second connecting groove; when the second lock cylinder is in the second position, the second lock cylinder pushes the transmission member to partially protrude from the second connecting groove, so that the transmission member engages with the actuating member.

[0007] As an optional implementation, a pushing slope is formed at the first end of the second lock cylinder shaft; when the second lock cylinder shaft moves from the first position to the second position, the pushing slope can move relative to the transmission member and push against the transmission member.

[0008] As an optional implementation, the transmission component is a ball bearing.

[0009] As an optional implementation, the actuating member is provided with a transmission groove, which is sleeved on the second end of the first lock cylinder shaft. The transmission groove surrounds the connecting groove, and multiple locking positions are uniformly formed on the sidewall of the transmission groove. When the second lock cylinder shaft is in the second position, the second lock cylinder shaft pushes the transmission member to partially expose it in the connecting groove, so that the transmission member engages with any of the locking positions.

[0010] As an optional implementation, the actuating member is provided with a limiting groove, the limiting groove is connected to the transmission groove, and the circumference of the second lock cylinder shaft is provided with a limiting sidewall, the limiting sidewall is connected to the limiting groove to restrict the relative rotation between the second lock cylinder shaft and the actuating member.

[0011] As an optional implementation, the driving component is an electromagnet, and the second lock core shaft passes through the electromagnet. When the electromagnet is energized, it can magnetically drive the second lock core shaft to move to the second position.

[0012] As an optional implementation, the second end of the second lock cylinder shaft is located away from the first lock cylinder shaft, and a permanent magnet is provided inside the second end of the second lock cylinder shaft.

[0013] As an optional implementation, the smart lock cylinder further includes a reset elastic element. When the drive element is de-energized, the reset elastic element is configured to forcefully drive the second lock cylinder shaft to reset to the first position.

[0014] As an optional implementation, a gear set is provided between the first lock core shaft and the generator shaft. When the first lock core shaft rotates, it can drive the gear set to rotate. Under the drive of the gear set, the generator shaft rotates to generate electricity.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] Firstly, the clutch structure, consisting of the first lock cylinder shaft, the second lock cylinder shaft, the transmission component, and the drive component, is all located within the lock cylinder body. The circuit board and generator are also located within the lock cylinder body, highly integrating the functions of the smart lock into the space required to install a conventional mechanical lock cylinder. This integrated design significantly simplifies the structure of the smart lock, reduces the number of parts, and lowers production costs and installation difficulty. Power is generated by capturing the energy from the user's rotation of the first lock cylinder shaft, thereby enabling communication, authentication, and unlocking control. Unlocking verification can be completed via a mobile app or other authentication methods, and the unlocking action itself is powered by the user. This self-generating design frees the smart lock cylinder from dependence on an external power source, achieving smart lock functionality without the use of batteries, and solving the problems of complex structure, inconvenient installation, and the need for regular battery replacement / charging in existing smart locks. Furthermore, existing lock-related components do not require modification for this smart lock cylinder. This smart lock cylinder allows users to seamlessly upgrade their mechanical locks to smart locks without changing any other components (such as the door or lock body) or any user habits. This eliminates the burden of carrying and the risk of losing physical keys, and avoids the incompatibility issues with doors and lock bodies, as well as the need for regular charging / battery replacements present in existing smart locks. At the same time, cracking smart locks, which use electronic circuits and modern cryptographic algorithms as their core authentication methods, is significantly more difficult than cracking traditional mechanical locks, resulting in a substantial increase in security.

[0017] Secondly, when the first lock cylinder shaft needs to be rotated to drive the actuating component, the alignment between the transmission component and the actuating component is relatively convenient and precise. Due to the reasonable design of the connecting groove and the transmission and actuating components, the transmission component easily connects with the actuating component, facilitating a stable transmission among the first lock cylinder shaft, transmission component, and actuating component. This reduces energy loss and errors during transmission, improving the accuracy and reliability of unlocking. Furthermore, the power consumption of driving the transmission component and the second lock cylinder shaft is low, requiring less power from the generator. Because of the reasonable design of the clutch structure, the driving component only needs to move the second lock cylinder shaft a short distance when authentication is successful to connect the transmission component and the actuating component, thus consuming less energy. Once the user's identity is verified, the energy requirements for driving the transmission component and the second lock cylinder shaft are met, and the clutch between the first lock cylinder shaft and the actuating component can be quickly engaged without complex alignment or multiple drives of the second lock cylinder shaft, resulting in low energy consumption and a good user experience.

[0018] Thirdly, for legitimate users, after successful authentication, simply rotating the first lock cylinder shaft activates the generator and drive mechanism, connecting the transmission and actuating components to smoothly unlock the door. The entire process is natural and smooth, conforming to user habits and closely resembling the unlocking action of existing mechanical lock cylinders, providing a superior unlocking experience. When faced with unauthorized unlocking attempts, the drive mechanism stops due to failed authentication, causing the first lock cylinder shaft to spin freely. Unauthorized individuals cannot open the lock by rotating the first lock cylinder shaft. This design ensures convenience while effectively preventing illegal intrusion, eliminating concerns about the lock cylinder being easily cracked and further enhancing user trust and satisfaction with the smart lock cylinder.

[0032] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0033] Please see Figures 1 to 5As shown in the figure, this application embodiment provides an intelligent lock cylinder, which includes a lock cylinder body 3, a first lock cylinder shaft 1, a second lock cylinder shaft 2, a toggle member 4, a transmission member 5, and a drive member 6. The first lock cylinder shaft 1 can rotate freely around its own axis, and the second lock cylinder shaft 2 can rotate freely around its own axis. The first lock cylinder shaft 1 and the second lock cylinder shaft 2 are coaxially arranged. The first lock cylinder shaft 1 is rotatably mounted on the lock cylinder body 3, and a connecting groove 11 is provided at the second end of the first lock cylinder shaft 1. The second lock cylinder shaft 2 is rotatably mounted on the lock cylinder body 3, and the second lock cylinder... The first end of the spindle 2 is slidably mounted in the connecting groove 11; the actuating element 4 is connected to the second lock cylinder spindle 2, and the actuating element 4 and the second lock cylinder spindle 2 rotate synchronously. The actuating element 4 is used for transmission connection with the lock tongue; the transmission element 5 is movably mounted in the connecting groove 11; the driving element 6 is mounted on the lock cylinder body 3. When the driving element 6 is de-energized, the second lock cylinder spindle 2 is in the first position. When the driving element 6 is energized, it is used to drive the second lock cylinder spindle 2 to move axially from the first position to the second position relative to the actuating element 4; when the second lock cylinder spindle 2 is in the first position (see details...), Figure 2 The transmission component 5 and the actuating component 4 are separated. When the first lock core shaft 1 rotates, the actuating component 4 remains stationary; when the second lock core shaft 2 is in the second position (see details...), the transmission component 5 and the actuating component 4 remain stationary. Figure 3 The first end of the second lock core shaft 2 pushes the transmission member 5 to partially protrude from the connecting groove 11, so that the transmission member 5 and the actuating member 4 are engaged. The rotation of the first lock core shaft 1 can drive the actuating member 4 and the second lock core shaft 2 to rotate synchronously through the transmission member 5. Furthermore, the smart lock cylinder also includes a generator 8 and a circuit board 9, both disposed on the main body 3 of the lock cylinder. The first lock cylinder shaft 1 and the generator 8 are connected by a rotating shaft transmission. The generator 8 is electrically connected to the circuit board 9 and the drive component 6 respectively. When the first lock cylinder shaft 1 rotates, it can drive the generator 8 to generate electricity to supply power to the circuit board 9 and the drive component 6. When the circuit board 9 is powered on, it can generate a control signal to control the start and stop of the drive component 6. Specifically, when the first lock cylinder shaft 1 rotates to drive the generator 8 to generate electricity, if the authentication fails, the circuit board 9 de-energizes the drive component 6 to put the drive component 6 in a stopped state. At this time, the first lock cylinder shaft 1 rotates idly and cannot drive the actuating component 4. When the first lock cylinder shaft 1 rotates to drive the generator 8 to generate electricity, if the authentication passes, the circuit board 9 energizes the drive component 6 to put the drive component 6 in a started state. The drive component 6 drives the second lock cylinder shaft 2 to move to the second position, thereby connecting the transmission component 5 and the actuating component 4. At this time, the rotation of the first lock cylinder shaft 1 can synchronously drive the actuating component 4.

[0034] The operating principle of this smart lock cylinder is as follows:

[0035] When unlocking or locking the lock in the room, the user can rotate the second lock cylinder shaft 2. Since the actuating element 4 rotates synchronously with the second lock cylinder shaft 2, the rotation of the second lock cylinder shaft 2 will drive the actuating element 4 to rotate synchronously. The actuating element 4 will drive the lock tongue to move, thereby realizing the unlocking or locking operation. The operation is simple and convenient.

[0036] When unlocking or locking from outside the room, under abnormal operation (i.e., when authentication fails), the drive unit 6 is de-energized and in a stopped state, the second lock cylinder shaft 2 is in the first position, and the transmission component 5 is located in the connecting groove 11 and separated from the actuating component 4. At this time, rotating the first lock cylinder shaft 1 from outside the room cannot drive the actuating component 4 to rotate, that is, it cannot drive the lock tongue to move, effectively preventing forced unlocking and ensuring the safety of the smart lock cylinder.

[0037] When unlocking or locking from outside the room, during normal operation (i.e., when authentication is successful), the drive unit 6 is powered on and in the start state. The drive unit 6 drives the second lock cylinder shaft 2 to move axially from the first position to the second position relative to the actuating member 4. The first end of the second lock cylinder shaft 2 pushes the transmission member 5 to partially protrude from the connecting groove 11 so that the transmission member 5 and the actuating member 4 are engaged. In addition, when the first lock cylinder shaft 1 is rotated from outside the room, the rotation of the first lock cylinder shaft 1 can drive the actuating member 4 to rotate synchronously through the transmission member 5.

[0038] Thus, the smart lock cylinder has at least the following beneficial technical effects:

[0039] Firstly, the clutch structure, consisting of the first lock cylinder shaft 1, the second lock cylinder shaft 2, the transmission component 5, and the drive component 6, is all located within the lock cylinder body 3. The circuit board 9 and the generator 8 are also located within the lock cylinder body 3, highly integrating the functions of the smart lock into the space required for installing a conventional mechanical lock cylinder. This integrated design significantly simplifies the structure of the smart lock, reduces the number of parts, and lowers production costs and installation difficulty. Power is generated by capturing the energy from the user's rotation of the first lock cylinder shaft 1, thereby enabling communication, authentication, and unlocking control. Unlocking verification can be completed via a mobile app or other authentication methods, and the unlocking action itself is powered by the user. This self-generating design frees the smart lock cylinder from dependence on external power sources, achieving smart lock functionality without the use of batteries, and solving the problems of complex structure, inconvenient installation, and the need for regular battery replacement / charging in existing smart locks. Furthermore, existing lock-related components do not require modification for this smart lock cylinder. This smart lock cylinder allows users to seamlessly upgrade their mechanical locks to smart locks without changing any other components (such as the door or lock body) or any user habits. This eliminates the burden of carrying and the risk of losing physical keys, and avoids the incompatibility issues with doors and lock bodies, as well as the need for regular charging / battery replacements present in existing smart locks. At the same time, cracking smart locks, which use electronic circuits and modern cryptographic algorithms as their core authentication methods, is significantly more difficult than cracking traditional mechanical locks, resulting in a substantial increase in security.

[0040] Secondly, when the first lock cylinder shaft 1 needs to be rotated to drive the actuating element 4, the alignment between the transmission element 5 and the actuating element 4 is relatively convenient and accurate. Due to the reasonable design of the connecting groove 11 and the transmission element 5 and actuating element 4, the transmission element 5 easily connects with the actuating element 4, facilitating a stable transmission among the first lock cylinder shaft 1, transmission element 5, and actuating element 4. This reduces energy loss and errors during transmission, improving the accuracy and reliability of unlocking. Furthermore, the power consumption of driving the transmission element 5 and the second lock cylinder shaft 2 is low, requiring less power from the generator 8. Because of the reasonable design of the clutch structure, the driving element 6 only needs to drive the second lock cylinder shaft 2 a short distance when authentication is successful to achieve the connection between the transmission element 5 and the actuating element 4, thus consuming less energy. Moreover, once the user's identity is verified, and the energy requirements for driving the transmission element 5 and the second lock cylinder shaft 2 are met, the clutch between the first lock cylinder shaft 1 and the actuating element 4 can be quickly engaged without complex alignment, resulting in low energy consumption and a good user experience.

[0041] Thirdly, for legitimate users, after successful authentication, simply rotating the first lock cylinder shaft 1 normally will activate the generator 8 and drive the drive component 6, connecting the transmission component 5 and the actuating component 4 to smoothly unlock the door. The entire process is natural and smooth, conforming to user habits, requiring no complicated operating steps, and providing a convenient unlocking experience. When faced with unauthorized unlocking attempts, because authentication fails, the drive component 6 is in a stopped state, and the first lock cylinder shaft 1 spins freely, preventing unauthorized unlockers from opening the lock by rotating it. This design ensures convenience while effectively preventing illegal intrusion, eliminating user concerns about the lock cylinder being easily cracked, further enhancing user trust and satisfaction with the smart lock cylinder.

[0042] In one implementation, the circuit board 9 may be, but is not limited to, a PCB, PCBA, FPC, or FPCB, etc., and can be selected according to actual needs. No single limitation is made here.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, the smart lock cylinder further includes a first handle 10 and a second handle 20. The first handle 10 is connected to the first end of the first lock cylinder shaft 1, and the second handle 20 is connected to the second end of the second lock cylinder shaft 2. Rotating the first handle 10 can drive the first lock cylinder shaft 1 to rotate synchronously, and rotating the second handle 20 can drive the second lock cylinder shaft 2 to rotate synchronously. The first handle 10 is used to be installed outside the room, and the second handle 20 is used to be installed inside the room.

[0044] In one embodiment, a gear set (not labeled) is provided between the first lock core shaft 1 and the rotating shaft of the generator 8. When the first lock core shaft 1 rotates, it can drive the gear set to rotate. Under the drive of the gear set, the rotating shaft of the generator 8 rotates so that the generator 8 generates electricity.

[0045] In one embodiment, the circuit board 9 is equipped with an authentication module and a drive module. The authentication module is used to authenticate the user's identity after the user rotates the lock cylinder shaft to power the generator 8 circuit board 9. Specific authentication methods include, but are not limited to, fingerprint authentication or establishing Bluetooth communication with the user's mobile phone APP for authentication. If the authentication is successful, the authentication module sends a signal to power the drive module to the drive component 6, thereby enabling the user to rotate the toggle component 4 to perform operations such as retracting the latch, releasing the deadbolt, and unlocking the deadbolt. If the authentication fails, the drive module does not power the drive component 6, and the user can only rotate the lock cylinder shaft to drive the generator 8 to generate electricity, but cannot rotate the toggle component 4.

[0046] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the connecting groove 11 includes a first connecting groove 111 extending axially along the first lock cylinder shaft 1 and a second connecting groove 112 extending radially along the first lock cylinder shaft 1. The first connecting groove 111 and the second connecting groove 112 are connected. The first end of the second lock cylinder shaft 2 is disposed in the first connecting groove 111, and the transmission member 5 is movably disposed in the second connecting groove 112. When the second lock cylinder shaft 2 is in the second position, the second lock cylinder shaft 2 pushes the transmission member 5 to partially protrude from the second connecting groove 112, so that the transmission member 5 is engaged with the actuating member 4. This design offers several advantages. First, the design of the first and second mounting slots provides a reasonable space for the placement and movement of the second lock cylinder shaft 2 and the transmission component 5, allowing for an orderly arrangement of components within a limited space and ensuring the compactness and stability of the entire lock cylinder structure. Second, when the second lock cylinder shaft 2 is in the second position, it can push the transmission component 5 to partially expose it in the second connecting slot 112, thereby achieving the engagement between the transmission component 5 and the actuating component 4. This precise transmission connection mechanism ensures that during a legal unlocking operation, the rotation of the first lock cylinder shaft 1 can be accurately transmitted to the actuating component 4 through the transmission component 5, achieving smooth unlocking. Compared to some lock cylinders with less precise transmission structures, this design significantly improves the success rate and reliability of unlocking. Third, due to the reasonable design of the connecting slot 11 and the transmission component 5, the friction and resistance during transmission are small, ensuring a stable and reliable engagement between the transmission component 5 and the actuating component 4. Even under frequent use, it can maintain good transmission performance, reducing unlocking failures caused by transmission malfunctions and further enhancing user satisfaction with the smart lock cylinder.

[0047] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, a pushing slope 21 is formed at the first end of the second lock core shaft 2; when the second lock core shaft 2 moves from the first position to the second position, the pushing slope 21 can move relative to the transmission member 5 and push against the transmission member 5. Thus, firstly, the first end of the second lock cylinder shaft 2 forms a pushing slope 21. When it moves from the first position to the second position, the pushing slope 21 moves relative to the transmission component 5 and pushes against the transmission component 5. This design makes the pushing process smoother and more fluid, reducing the impact and vibration caused by sudden force, reducing the risk of component damage, and ensuring the stability and reliability of the transmission process. Furthermore, the presence of the pushing slope 21 allows the second lock cylinder shaft 2 to accurately push the transmission component 5 until it is partially exposed in the second connecting groove 112, thereby achieving the engagement of the transmission component 5 and the actuating component 4. Compared with other pushing methods, the pushing slope 21 can better control the movement direction and force of the transmission component 5, ensuring the accuracy of the engagement, significantly improving the success rate of unlocking, and reducing the unlocking failure problem caused by inaccurate transmission. Secondly, the design of the pushing slope 21 cleverly utilizes the spatial relationship between the second lock cylinder shaft 2 and the transmission component 5, achieving the transmission function while... Without the need for additional complex structures or large spaces, the internal structure of the entire smart lock cylinder is more compact, which helps to reduce the size of the lock cylinder. The components can fit together tightly, reducing unnecessary gaps and redundant spaces, improving the overall integration and space utilization of the lock cylinder, and providing more space for the installation and functional implementation of other components. Thirdly, the contact and relative movement between the pushing slope 21 and the transmission component 5 are relatively smooth, reducing wear caused by direct collision and friction. Compared with other sharp or uneven pushing structures, the pushing slope 21 can better distribute the force, reduce the wear on the surface of the components, extend the service life of the second lock cylinder shaft 2 and the transmission component 5, reduce the frequency of maintenance and replacement of components, and the smooth pushing process reduces energy loss, so that the electrical energy generated by the generator 8 can be used more efficiently for the operation of the drive component 6 and other components, reducing energy waste and thus reducing the requirements for the power generation capacity of the generator 8.

[0048] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the first end of the second lock cylinder 2 has a head 24, and the pushing slope 21 is connected to the head 24. When the second lock cylinder 2 is moving to the second position, the pushing slope 21 pushes the transmission member 5 out of the second connecting groove 112. Finally, the head 24 abuts against the transmission member 5 to keep the transmission member 5 in a position that can form a transmission connection with the actuating member 4.

[0049] like Figure 2 , Figure 3 and Figure 4As shown, in one embodiment, the transmission component 5 is a ball bearing. This configuration has several advantages. First, due to its low rolling friction resistance, the ball bearing can quickly respond to the pushing action of the second lock cylinder shaft 2, rapidly moving to the appropriate position to engage with the actuating component 4. During legal unlocking, this rapid transmission response allows the user to quickly drive the actuating component 4 to unlock after rotating the first lock cylinder shaft 1, reducing unlocking waiting time and improving unlocking efficiency and smoothness. Second, the ball bearing typically has a small volume, occupying little space within the smart lock cylinder, allowing for a more compact overall structure and facilitating installation and use in situations with limited space for various door locks. Third, the ball bearing is spherical, possessing the characteristic of free rolling in all directions. When the second lock cylinder shaft 2 pushes against the ball bearing, the ball bearing can automatically adjust its angle and direction according to the position and shape of the actuating component 4, finding the optimal engagement position. Regardless of how the actuating component 4 changes its posture in space, the ball bearing can adapt to this change through its own rolling, ensuring reliable engagement.

[0050] It should be noted that in some other embodiments, the transmission component 5 may also be, but is not limited to, a sliding block or a sliding column, etc., and can be selected according to actual needs. There is no single limitation here.

[0051] like Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment, the actuating member 4 is provided with a transmission groove 41, which is sleeved on the second end of the first lock core shaft 1. The transmission groove 41 is arranged around the connecting groove 11, and a plurality of locking positions 411 are uniformly formed on the side wall of the transmission groove 41. When the second lock core shaft 2 is in the second position, the second lock core shaft 2 pushes the transmission member 5 to partially expose it in the connecting groove 11 so that the transmission member 5 is engaged with any locking position 411. With this configuration, firstly, the actuating member 4 has a transmission groove 41 inside and is sleeved on the second end of the first lock cylinder shaft 1. This sleeved structure provides a stable basis for the engagement between the actuating member 4 and the first lock cylinder shaft 1. When the second lock cylinder shaft 2 moves to the second position and pushes the transmission member 5 to protrude from the second connecting groove 112, the rotation of the first lock cylinder shaft 1 can be reliably transmitted to the actuating member 4 through the connection between the transmission member 5 and the transmission groove 41, reducing the shaking and deviation during the transmission process, ensuring the accurate execution of the unlocking action, and significantly improving the stability of the lock cylinder transmission. Secondly, the sidewall of the transmission groove 41 is uniformly formed with multiple locking positions 411. When the second lock cylinder shaft 2 is in the second position and pushes the transmission member 5 to protrude partially from the connecting groove 11, the transmission member 5 can engage with any locking position 411. The uniformly distributed locking positions 411 ensure that the transmission member 5 can find a suitable engaging position at any angle, guaranteeing the accuracy and reliability of the engagement. Even during frequent unlocking operations, the transmission component 5 can accurately engage with the locking position 411, avoiding unlocking failures caused by inaccurate engagement.

[0052] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, a limiting groove 42 is provided inside the actuating member 4, and the limiting groove 42 is connected to the transmission groove 41. A limiting sidewall 22 is provided on the periphery of the second lock cylinder shaft 2. The limiting sidewall 22 is connected to the limiting groove 42 to restrict the relative rotation between the second lock cylinder shaft 2 and the actuating member 4, and the limiting sidewall 22 can slide relative to the limiting groove 42 to allow the second lock cylinder shaft 2 to move axially relative to the actuating member 4. Thus, firstly, since the relative rotation is restricted, when the second lock cylinder shaft 2 is rotated, the second lock cylinder shaft 2 can accurately transmit power to the actuating member 4 to drive the actuating member 4 to rotate, avoiding transmission deviation caused by relative rotation; secondly, the limiting sidewall 22 can slide relative to the limiting groove 42, allowing the second lock cylinder shaft 2 to move axially relative to the actuating member 4. This design allows the second lock cylinder shaft 2 to switch between a first position and a second position to achieve different functions.

[0053] In one embodiment, the limiting sidewall 22 includes a plurality of first limiting surfaces distributed along the periphery of the second lock core shaft 2, and a plurality of second limiting surfaces are provided in the limiting groove 42, with the plurality of first limiting surfaces and the plurality of second limiting surfaces corresponding to each other.

[0054] In one embodiment, the driving component 6 is an electromagnet, and the second lock cylinder shaft 2 passes through the electromagnet. When the electromagnet is energized, it magnetically drives the second lock cylinder shaft 2 to move to the second position. Thus, firstly, the electromagnet can instantly generate a strong magnetic field after being energized, thereby quickly applying magnetic force to the second lock cylinder shaft 2 to drive it to the second position. Electromagnetic drive does not require a complex mechanical transmission process, and the response time is extremely short. For example, when a legitimate user performs an unlocking operation, the electromagnet can drive the second lock cylinder shaft 2 to its position almost instantly upon energization, making the unlocking process faster, significantly shortening the user's waiting time, and improving efficiency. Secondly, by rationally designing parameters such as the magnetic field strength of the electromagnet, the number of coil turns, and the material and size of the second lock cylinder shaft 2, the magnitude of the magnetic force exerted by the electromagnet on the second lock cylinder shaft 2 can be precisely controlled, thereby ensuring that the second lock cylinder shaft 2 can accurately move to the second position. This precise control avoids problems such as unlocking failure or component damage caused by inaccurate movement, improving the reliability and stability of the smart lock cylinder.

[0055] like Figure 2 , Figure 3 and Figure 4As shown, in one embodiment, the second end of the second lock cylinder shaft 2 is located away from the first lock cylinder shaft 1, and a permanent magnet 23 is disposed inside the second end of the second lock cylinder shaft 2. Thus, the permanent magnet 23 at the second end of the second lock cylinder shaft 2 allows for more efficient drive coordination with the electromagnet, which serves as the driving element 6. When the electromagnet is energized, the generated magnetic field interacts with the magnetic field of the permanent magnet 23, generating a powerful driving force. This enables the second lock cylinder shaft 2 to move quickly and accurately to the second position. Compared to relying solely on the electromagnet's own magnetic field for drive, the presence of the permanent magnet 23 enhances the magnetic field effect, improves the drive response speed and force, ensures rapid completion of the unlocking action, and improves the user experience.

[0056] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the smart lock cylinder further includes a reset elastic element 7. When the drive element 6 is de-energized, the reset elastic element 7 is configured to elastically drive the second lock cylinder shaft 2 to reset to the first position. With this configuration, after the drive element 6 (such as an electromagnet) is de-energized, the reset elastic element 7 can automatically elastically drive the second lock cylinder shaft 2 to reset to the first position. This means that after the user completes the unlocking operation, there is no need to manually perform an additional reset action. Specifically, when the second lock cylinder shaft 2 resets to the first position, the transmission element 5 will not be subjected to the pushing force of the second lock cylinder end. When the transmission element 5 is slightly vibrated, the transmission element 5 will move back to the position separated from the toggle element 4.

[0057] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the first lock cylinder shaft 1 includes a shaft body 12 and a rotating sleeve 13. The rotating sleeve 13 is connected to one end of the shaft body 12, and the rotating sleeve and the shaft body 12 rotate synchronously. The connecting groove 11 is formed in the rotating sleeve 13.

[0058] like Figure 4 and Figure 5 As shown, in one embodiment, a synchronously rotating toggle block 43 is provided on one side of the toggle member 4, and the toggle block 43 is used to be connected to the locking tongue drive.

[0059] In summary, the intelligent lock cylinder disclosed in this utility model can bring at least the following beneficial technical effects:

[0060] (1) The clutch structure consisting of the first lock cylinder shaft 1, the second lock cylinder shaft 2, the transmission component 5, and the driving component 6 is located inside the lock cylinder body 3. The circuit board 9 and the generator 8 are also located inside the lock cylinder body 3, thus highly integrating the functions of the smart lock into the space required to install a conventional mechanical lock cylinder. This integrated design significantly simplifies the structure of the smart lock, reduces the number of parts, lowers production costs and installation difficulty. Furthermore, rotating the first lock cylinder shaft 1 drives the generator 8 to generate electricity, which powers the circuit board 9 and the driving component 6. This self-generating design frees the smart lock cylinder from dependence on external power sources.

[0061] (2) By setting up the transmission component 5 and realizing the engagement or separation of the transmission component 5 and the actuating component 4 under the action of the driving component 6, the problem of inconvenient connection and alignment between the locking end and the actuating component 4 and the difficulty in forming a stable transmission in the prior art is solved, which improves the transmission stability and ease of use of the smart lock core, while ensuring the safety of the smart lock core.

[0062] (3) The ball is spherical and has the characteristic of rolling freely in all directions. When the second lock core shaft 2 pushes the ball, the ball can automatically adjust its angle and direction according to the position and shape of the actuating part 4 to find the best locking position. No matter how the actuating part 4 changes its posture in space, the ball can adapt to this change through its own rolling to ensure the reliability of the locking.

[0063] (4) The actuating member 4 is provided with a transmission groove 41 and is sleeved on the second end of the first lock core shaft 1. This sleeved structure provides a stable base for the actuating member 4 and the first lock core shaft 1. When the second lock core shaft 2 moves to the second position and pushes the transmission member 5 to be exposed in the second connecting groove 112, the rotation of the first lock core shaft 1 can be reliably transmitted to the actuating member 4 through the connection between the transmission member 5 and the transmission groove 41, reducing the shaking and deviation during the transmission process.

[0064] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
