Description
Technical Field
[0001] This utility model belongs to the field of smart lock technology, specifically relating to a smart lock cylinder. Background Technology
[0002] Currently, entry doors with smart locks typically consist of three parts: the door leaf, the lock body, and the smart lock itself. The smart lock itself comprises at least a front panel, connectors, a transmission mechanism, and a rear panel. Some smart locks 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 also require the battery module to be installed inside the door leaf. This complex structure presents several unresolved problems: 1. Compatibility Issues: Existing smart locks have poor door compatibility. Different types and sizes of doors vary in thickness, material, and installation space. For doors that are thinner or where drilling to install connectors is inconvenient, such as metal doors, expensive solid wood doors, or doors with special structures, it is impossible to upgrade the original mechanical door lock to a smart door lock. This limits the adoption of smart door locks, preventing many users from enjoying the security and convenience they offer.
[0003] 2. Power Supply Issues: Currently, smart locks primarily rely on batteries or external power sources. Once the internal battery is depleted, users must use a power bank or similar means for emergency power; otherwise, the door cannot be opened, causing significant inconvenience. Furthermore, existing smart locks require regular battery replacement or charging, increasing operating costs and forcing users to constantly monitor battery levels for timely replacement or recharging. Smart locks using dry-cell batteries also generate waste batteries, potentially polluting the environment. In addition, battery performance is significantly affected by ambient temperature; in excessively hot or cold regions, battery life and stability decrease, impacting the smart lock's usability in those conditions. Utility Model Content
[0004] To overcome at least one of the defects described in the prior art, this utility model provides an intelligent lock cylinder to solve the problems of complex structure, inconvenient installation, poor compatibility, and reliance on external power supply in existing intelligent lock cylinders. Through highly integrated design, self-generating technology, and intelligent security control mechanisms, the intelligent lock cylinder achieves high compatibility and high security without requiring external power supply or built-in batteries.
[0005] The technical solution adopted by this utility model to solve its problem is: A smart lock cylinder, characterized in that it comprises: a lock cylinder body; a lock cylinder shaft rotatably disposed on the lock cylinder body; an actuating member rotatably disposed on the lock cylinder body, the actuating member being used for transmission connection with the lock tongue, a first end of the actuating member and a second end of the lock cylinder shaft being sleeved and connected; one of the first end of the actuating member and the second end of the lock cylinder shaft being provided with a transmission hole, and the other being provided with a connecting hole; the transmission hole surrounding the connecting hole, the wall of the connecting hole being provided with a through connecting groove, and the actuating member also having a mounting cavity communicating with the connecting groove; a transmission member movable within the connecting groove; and a driving member. A drive member is disposed within the mounting cavity; a movable member is connected to the drive member and is at least partially movably disposed within the connecting hole; when the drive member is energized, it can drive the movable member to move from a first position to a second position relative to the connecting hole; when the movable member is in the first position, the drive member and the drive hole are separated, and the actuating member remains stationary when the lock cylinder shaft rotates; when the movable member is in the second position, the movable member pushes against the drive member, so that part of the drive member is exposed in the connecting groove and connected to the drive hole, and the actuating member can be driven to rotate synchronously through the drive member when the lock cylinder shaft rotates.
[0006] As an optional implementation, the smart lock cylinder further includes a generator and a circuit board. The lock cylinder shaft and the generator shaft are connected by a drive, the generator and the circuit board are electrically connected, and the circuit board and the drive component are electrically connected. When the lock cylinder shaft rotates, it can drive the generator to generate electricity to power the circuit board and the drive component. When the circuit board is powered on, it can generate a control signal to control the start and stop of the drive component.
[0007] As an optional implementation, the driving component is fixedly disposed in the mounting cavity. When the actuating component rotates, it drives the driving component to rotate synchronously.

The conductive ring and the driving component are electrically connected, and the conductive sheet abuts against the conductive ring.
[0008] As an optional implementation, the movable component is a sliding component, and the sliding component is partially disposed within the connecting hole. When the driving component is energized, it can drive the movable component to slide axially relative to the connecting hole. When the sliding component is in the first position, the transmission component and the transmission hole are separated, and the actuating component remains stationary when the lock cylinder shaft rotates. When the sliding component is in the second position, the sliding component pushes against the transmission component, so that the transmission component is partially exposed in the connecting groove and connected to the transmission hole. When the lock cylinder shaft rotates, the actuating component can be driven to rotate synchronously through the transmission component.

When the rotating wheel rotates to the first position, the clearance portion abuts against the transmission component, and the transmission component is located within the connecting groove and separated from the transmission hole. When the lock cylinder shaft rotates, the actuating component remains stationary. When the rotating wheel rotates to the second position, the push-out portion abuts against the transmission component, and the push-out portion pushes against the transmission component, so that part of the transmission component is exposed in the connecting groove and connected to the transmission hole. When the lock cylinder shaft rotates, the actuating component can be driven to rotate synchronously through the transmission component.
[0013] As an optional implementation, the driving component is a coreless motor.

[0019] As an optional implementation, the smart lock cylinder further includes a first handle and a second handle. The first handle is connected to the lock cylinder shaft, and the second handle is connected to the end of the actuating member away from the lock cylinder shaft. Rotating the first handle can drive the lock cylinder shaft to rotate synchronously, and rotating the second handle can drive the actuating member to rotate synchronously.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the clutch structure, consisting of moving parts, transmission parts, and drive parts, is integrated within the lock cylinder body. The circuit board and generator are also integrated 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 greatly 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 authenticators; 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 or energy storage devices with liquid electrolytes. This solves the problems of complex structure, inconvenient installation, and the need for periodic battery replacement / charging found in existing smart locks. Furthermore, existing lock-related components do not require adaptation for this smart lock cylinder. This smart lock cylinder allows users to directly replace mechanical locks with 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.
[0021] Secondly, the driving component is located within the mounting cavity of the actuating component, the movable component is located between the driving component and the connecting hole, and the transmission component is located within the connecting groove. This compact structural design reduces mutual interference between components. During long-term use, these components are less susceptible to external factors such as dust and moisture, thus reducing the probability of malfunctions and extending the lifespan of the smart lock cylinder. Furthermore, due to the small size of the movable component, the power consumption required to drive it is low. In battery-free smart lock cylinders, the electrical energy generated by the smart lock cylinder itself is sufficient to drive the movable component to move accurately into place, enabling the transmission component to form a stable transmission connection with the transmission hole. This not only reduces the performance requirements of the driving component but also improves the engagement and disengagement reliability between the lock cylinder shaft and the actuating component. The clutch structure, composed of driving components, moving components, transmission components, and transmission holes, occupies less space, making the entire smart lock cylinder more compact. This miniaturized design not only facilitates the installation and maintenance of the smart lock cylinder but also adapts to the installation needs of door locks of different sizes, improving the product's versatility. Furthermore, the compact structural design optimizes the use of internal space in the smart lock cylinder, making the layout between components more reasonable and reducing unnecessary space waste. This not only improves the overall performance of the smart lock cylinder but also provides space for possible future functional expansion.
[0022] Thirdly, when the actuating component needs to be driven to rotate by rotating the lock cylinder shaft, the alignment process between the transmission component and the transmission hole is precise and convenient. Due to the reasonable structural design, the transmission component can be smoothly partially exposed in the connecting groove under the push of the moving component and tightly connected with the transmission hole to form a stable transmission relationship. This precise transmission connection method avoids the problem of unlocking or locking failure caused by inaccurate transmission, thus improving the reliability of the smart lock cylinder. Furthermore, the power consumption of driving the transmission component and the moving component is very low, and the power requirement of the generator is low. Moreover, once the user's identity is verified, the energy demand of driving the transmission component and the moving component is met simultaneously, and the clutch between the lock cylinder shaft and the actuating component can be quickly engaged without complicated alignment. It has the characteristics of low energy demand and good user experience.
[0023] Fourthly, when authentication fails, the circuit board de-energizes the drive unit, putting it in a stopped state. At this time, the lock cylinder shaft spins freely and cannot drive the actuating component, preventing forced unlocking. When authentication succeeds, the circuit board energizes the drive unit, putting it in a starting state. The drive unit moves the movable component to the second position, connecting the transmission component and the transmission hole. The rotation of the lock cylinder shaft can synchronously drive the actuating component to rotate, realizing normal unlocking or locking operations. This intelligent control method ensures that only authorized users can perform unlocking operations, and the unlocking action is consistent with that of traditional mechanical lock cylinders. This allows users to enjoy the advantages of smart locks, such as not needing to carry physical keys and high security, without changing their unlocking habits. Attached Figure Description

[0032] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0033] Example 1 Please see Figures 1 to 5 This application discloses an intelligent lock cylinder, including a lock cylinder body 1, a lock cylinder shaft 2, an actuating member 3, a transmission member 4, a driving member 5, and a movable member 6. The lock cylinder shaft 2 is rotatably mounted on the lock cylinder body 1. The actuating member 3 is rotatably mounted on the lock cylinder body 1 and is used for transmission connection with the lock tongue. The first end of the actuating member 3 and the second end of the lock cylinder shaft 2 are sleeved and connected. One of the first end of the actuating member 3 and the second end of the lock cylinder shaft 2 is provided with a transmission hole 80, and the other is provided with a connecting hole 90. The transmission hole 80 is arranged around the connecting hole 90, and the connecting hole... The hole wall of 90 is provided with a through connecting groove 901, which connects the transmission hole 80 and the connecting hole 90. The actuating member 3 is also provided with a mounting cavity 31 that communicates with the connecting groove 901. The transmission member 4 is movable within the connecting groove 901. The driving member 5 is disposed within the mounting cavity 31. The movable member 6 is connected to the driving member 5 and is at least partially movable within the connecting hole 90. When the driving member 5 is energized, it can drive the movable member 6 to move from a first position to a second position relative to the connecting hole 90. When the movable member 6 is in the first position, please refer to the following for details. Figure 2 When the transmission component 4 and the transmission hole 80 are separated, the actuating component 3 remains stationary when the lock core shaft 2 rotates; when the movable component 6 is in the second position, please refer to the following for details. Figure 3The movable part 6 pushes against the transmission part 4, so that part of the transmission part 4 is exposed in the connecting groove 901 and connected to the transmission hole 80. When the lock cylinder shaft 2 rotates, it can drive the actuating part 3 to rotate synchronously through the transmission part 4. Furthermore, the smart lock cylinder also includes a generator 7 and a circuit board 8, both of which are set in the lock cylinder body 1. The lock cylinder shaft 2 and the generator 7 are connected by a rotating shaft drive, the generator 7 and the circuit board 8 are electrically connected, and the circuit board 8 and the driving part 5 are electrically connected. When the lock cylinder shaft 2 rotates, it can drive the generator 7 to generate electricity to power the circuit board 8 and the driving part 5. When the circuit board 8 is powered on, it can generate a control signal to control the start and stop of the driving part 5. Specifically, when rotating the lock cylinder shaft 2 to drive the generator 7 to generate electricity, if the authentication fails, the circuit board 8 de-energizes the drive component 5 to put the drive component 5 in a stopped state. At this time, the lock cylinder shaft 2 spins freely and cannot drive the actuating component 3. When rotating the lock cylinder shaft 2 to drive the generator 7 to generate electricity, if the authentication passes, the circuit board 8 energizes the drive component 5 to put the drive component 5 in a start state. The drive component 5 drives the movable component 6 to move to the second position, thereby connecting the transmission component 4 and the transmission hole 80. At this time, the rotation of the lock cylinder shaft 2 can synchronously drive the actuating component 3 to rotate.
[0034] The operating principle of this smart lock cylinder is as follows: When unlocking or locking the room, users do not need a complicated authentication process. They can directly turn the lever 3. The transmission connection between the lever 3 and the lock tongue is tight and smooth. When the lever 3 is turned, the lock tongue can quickly and accurately make the corresponding action, realizing fast unlocking or locking, which greatly saves users' time and energy. It is especially suitable for quick entry and exit in emergency situations.
[0035] When unlocking or locking from outside the room, under abnormal operation (i.e., when authentication fails), the drive component 5 is de-energized and in a stopped state, the moving component 6 is in the first position relative to the connecting hole 90, and the transmission component 4 is located in the connecting groove 901 and separated from the actuating component 3. At this time, rotating the lock cylinder shaft 2 from outside the room cannot drive the actuating component 3 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.
[0036] When unlocking or locking from outside the room, under normal operation (i.e., when authentication is successful), the drive component 5 is powered on and in the start state. The drive component 5 drives the movable component 6 to move from the first position to the second position relative to the connecting hole 90. The movable component 6 pushes the transmission component 4 until it is partially exposed in the connecting groove 901, so that the transmission component 4 is engaged with the transmission hole 80. In addition, when the lock cylinder shaft 2 is rotated from outside the room, the rotation of the lock cylinder shaft 2 can drive the actuating component 3 to rotate synchronously through the transmission between the transmission component 4 and the transmission hole 80. The entire operation process is simple and efficient. The drive component 5 responds quickly after being powered on, driving the movable component 6 to move accurately to the second position, so that the transmission component 4 is reliably connected with the transmission hole 80. At this time, rotating the lock cylinder shaft 2 can quickly drive the actuating component 3 to rotate synchronously, thereby realizing the unlocking or locking operation. The whole process is smooth and natural, without any jamming or delay, improving the user experience.
[0037] The smart lock cylinder disclosed in this application has at least the following technical effects: Firstly, the clutch structure, consisting of the moving part 6, the transmission part 4, and the driving part 5, is integrated within the lock cylinder body 1. The circuit board 8 and the generator 7 are also integrated within the lock cylinder body 1, highly integrating the functions of the smart lock into the space required for installing a conventional mechanical lock cylinder. This integrated design greatly 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 authenticators; 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 or energy storage devices with liquid electrolytes. This solves the problems of complex structure, inconvenient installation, and the need for periodic battery replacement / charging found in existing smart locks. Furthermore, existing lock-related components do not require adaptation for this smart lock cylinder. This smart lock cylinder allows users to directly replace mechanical locks with 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.
[0038] Secondly, the driving component 5 is located within the mounting cavity 31 of the actuating component 3, the movable component 6 is located between the driving component 5 and the connecting hole 90, and the transmission component 4 is located within the connecting groove 901. This compact structural design reduces mutual interference between components. During long-term use, these components are less susceptible to external factors such as dust and moisture, thus reducing the probability of malfunctions and extending the lifespan of the smart lock cylinder. Furthermore, due to the small size of the movable component 6, the power consumption required to drive it is low. In a battery-free smart lock cylinder, the self-generated electrical energy is sufficient to drive the movable component 6 to move accurately into place, enabling the transmission component 4 to form a stable transmission connection with the transmission hole 80. This not only reduces the performance requirements of the driving component 5 but also improves the clutch reliability between the lock cylinder shaft 2 and the actuating component 3. The clutch structure composed of the driving component 5, movable component 6, transmission component 4, and transmission hole 80 occupies less space, making the entire smart lock cylinder structure more compact. This miniaturized design not only facilitates the installation and maintenance of the smart lock cylinder but also adapts to the installation requirements of door locks of different sizes, improving the product's versatility and providing space for possible future functional expansion.
[0039] Thirdly, when the lock cylinder shaft 2 is rotated to drive the actuating component 3, the alignment process between the transmission component 4 and the transmission hole 80 is precise and convenient. Due to the reasonable structural design, the transmission component 4 can be smoothly partially exposed in the connecting groove 901 under the push of the movable component 6 and tightly connected with the transmission hole 80 to form a stable transmission relationship. This precise transmission connection method avoids the problem of unlocking or locking failure caused by inaccurate transmission, thus improving the reliability of the smart lock cylinder. Furthermore, the power consumption of driving the transmission component 4 and the movable component 6 is very low, and the power requirement of the generator 7 is low. Moreover, once the user's identity is verified, the energy demand of driving the transmission component 4 and the movable component 6 is simultaneously met, and the clutch between the lock cylinder shaft 2 and the actuating component 3 can be quickly engaged without complicated alignment. It has the characteristics of low energy demand and good user experience.
[0040] Fourthly, when authentication fails, circuit board 8 de-energizes drive component 5, putting it in a stopped state. At this time, lock cylinder shaft 2 spins freely and cannot drive toggle component 3, effectively preventing forced unlocking and greatly improving the security of the smart lock cylinder. When authentication succeeds, circuit board 8 energizes drive component 5, putting it in a start state. Drive component 5 drives movable component 6 to the second position, connecting transmission component 4 and transmission hole 80. The rotation of lock cylinder shaft 2 can synchronously drive toggle component 3 to rotate, realizing normal unlocking or locking operations. This intelligent control method ensures that only authorized users can perform unlocking operations, further enhancing the security performance of the smart lock cylinder.
[0041] like Figure 2 and Figure 3As shown, in one embodiment, the first end of the actuating member 3 is sleeved on the outside of the second end of the lock cylinder shaft 2, the first end of the actuating member 3 is provided with a transmission hole 80, and the second end of the lock cylinder shaft 2 is provided with a connecting hole 90.
[0042] like Figure 2 and Figure 3 As shown, in one embodiment, the lock cylinder shaft 2 includes a shaft body 21 and a rotating sleeve 22. The rotating sleeve 22 is connected to one end of the shaft body 21, and the shaft body 21 and the rotating sleeve 22 can rotate synchronously. The second end of the lock cylinder shaft 2 is the rotating sleeve 22, and the aforementioned connecting hole 90 is provided inside the rotating sleeve 22.
[0043] In another embodiment, the second end of the lock cylinder 2 is sleeved on the outside of the first end of the actuating member 3, the first end of the actuating member 3 is provided with a connecting hole 90, and the second end of the lock cylinder 2 is provided with a transmission hole 80.
[0044] In one embodiment, a gear set (not shown) is provided between the lock core shaft 2 and the rotating shaft of the generator 7. When the lock core shaft 2 rotates, it can drive the gear set to rotate. Under the drive of the gear set, the rotating shaft of the generator 7 rotates to generate electricity.
[0045] It should be noted that in some other embodiments, the lock core shaft 2 and the generator 7 may also be, but are not limited to, belt drive structures or chain drive structures, etc., and can be selected according to actual needs, without being limited to one.
[0046] In one embodiment, the circuit board 8 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 2 to power the generator 7 circuit board 8. The 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 5, thereby enabling the user to rotate the toggle component 3 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 5, and the user can only rotate the lock cylinder shaft 2 to drive the generator 7 to generate electricity, but cannot rotate the toggle component 3.
[0047] like Figure 2 and Figure 3As 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 lock cylinder shaft 2, and the second handle 20 is connected to the end of the actuating element 3 away from the lock cylinder shaft 2 (i.e., the second end of the actuating element 3). Rotating the first handle 10 can drive the lock cylinder shaft 2 to rotate synchronously, and rotating the second handle 20 can drive the actuating element 3 to rotate synchronously. With this configuration, firstly, the first handle 10 connected to the lock cylinder shaft 2 and the second handle 20 connected to the end of the actuating element 3 away from the lock cylinder shaft 2 provide users with two different operating methods. Inside the room, users can directly rotate the second handle 20 to drive the actuating element 3 to rotate synchronously, achieving quick unlocking or locking without complicated operating procedures. Secondly, outside the room, users can rotate the first handle 10 to drive the lock cylinder shaft 2 to rotate synchronously. Combined with a user authentication system, after successful authentication, the unlocking or locking operation can be performed. This dual-handle design meets the usage habits and needs of different users in different scenarios, improving the ease of operation and flexibility of the smart lock cylinder. Thirdly, the first handle 10 and the second handle 20 correspond to different operating logics. Outside the room, simply turning the first handle 10 cannot unlock the door directly. It must be combined with the user authentication system. Only after successful authentication can the unlocking operation be performed, which effectively prevents unauthorized personnel from unlocking the door by forcibly turning the handle, and greatly improves the security of the smart lock cylinder.
[0048] like Figure 2 , Figure 4 and Figure 5As shown, in one embodiment, the driving component 5 is fixedly disposed within the mounting cavity 31. When the actuating component 3 rotates, it drives the driving component 5 to rotate synchronously. The smart lock cylinder also includes a brush structure 40, which includes a conductive sheet 402 and a conductive ring 401. The conductive sheet 402 is disposed on the circuit board 8, and the conductive ring 401 is arranged around the actuating component 3. The conductive ring 401 and the driving component 5 are electrically connected, and the conductive sheet 402 abuts against the conductive ring 401. With this configuration, firstly, the driving component 5 is fixed within the mounting cavity 31, and when the actuating component 3 rotates, it drives the driving component 5 to rotate synchronously. The circuit board 8 and the driving component 5 are electrically connected through the brush structure 40 (conductive sheet 402 and conductive ring 401). This design ensures that the circuit board 8 can continuously supply power to the driving component 5 during its rotation. Regardless of the rotation state of the driving component 5, the conductive sheet 402 and the conductive ring 401 always remain in contact, avoiding power interruption due to rotation and ensuring stable operation of the driving component 5. Secondly, the brush structure 40 adopts a design where the conductive sheet 402 is set on the circuit board 8 and the conductive ring 401 is set around the actuating component 3. The structure is compact and does not occupy too much extra space. During installation, there is no need for additional complicated wiring and connection operations. Simply install the circuit board 8 and the driving component 5 correctly into the mounting cavity 31, and the conductive sheet 402 and the conductive ring 401 will automatically make contact and electrical connection. This simplifies the installation process, improves installation efficiency, and reduces installation costs. In the limited mounting cavity 31 of the smart lock cylinder, this design can make full use of the space, making the layout of each component more reasonable and avoiding space waste caused by structural complexity. It is conducive to the miniaturization design of the smart lock cylinder and is easy to install in door locks of different specifications. Thirdly, in addition to power supply, the brush structure 40 also provides a reliable path for signal transmission between the circuit board 8 and the drive unit 5. The circuit board 8 can send control signals to the drive unit 5 through the brush structure 40, and the drive unit 5 can also feed back its own status information to the circuit board 8. For example, the circuit board 8 can send start or stop signals to the drive unit 5 through the brush structure 40 according to the user authentication result. The drive unit 5 can feed back its own rotation status, fault information, etc. to the circuit board 8, so that the circuit board 8 can make corresponding processing and adjustments, thereby improving the intelligence level and reliability of the smart lock cylinder.
[0049] In one implementation, the circuit board 8 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.
[0050] like Figure 4 and Figure 5 As shown, in one embodiment, the smart lock cylinder further includes a connecting seat 50, which is fixedly disposed on the second end of the actuating member 3 and rotates synchronously with the actuating member 3. The aforementioned conductive ring 401 is arranged around the connecting seat 50.
[0051] like Figure 5As shown, in one embodiment, the wall of the transmission hole 80 is provided with multiple locking positions 801. When the movable member 6 is in the second position, the movable member 6 pushes against the transmission member 4, so that part of the transmission member 4 is exposed in the connecting groove 901 and connected to any locking position 801. Thus, with multiple locking positions 801 on the wall of the transmission hole 80, when the movable member 6 is in the second position and pushes against the transmission member 4, so that part of the transmission member 4 is exposed in the connecting groove 901 and connected to any locking position 801, this multi-locking-position 801 design provides multiple connection options. Compared to a single locking position 801 connection, the multi-locking-position 801 design can select the nearest locking position 801 for connection based on the actual position and force of the transmission member 4, significantly reducing the circumferential travel required to establish transmission between the transmission member 4 and the transmission hole 80 after certification. This effectively reduces the power consumption and time of clutch engagement, providing a better user experience.
[0052] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in one embodiment, the movable member 6 is a sliding member 61, which is partially disposed in the connecting hole 90. When the driving member 5 is energized, it can drive the movable member 6 to slide axially relative to the connecting hole 90. When the sliding member 61 is in the first position, the transmission member 4 and the transmission hole 80 are separated, and the actuating member 3 remains stationary when the lock core shaft 2 rotates. When the sliding member 61 is in the second position, the sliding member 61 pushes against the transmission member 4 so that part of the transmission member 4 is exposed in the connecting groove 901 and connected to the transmission hole 80. When the lock core shaft 2 rotates, the actuating member 3 can be driven to rotate synchronously through the transmission member 4. With this configuration, firstly, the movable part 6 adopts a sliding part 61 design and can slide axially relative to the connecting hole 90, allowing for precise switching between the first and second positions. When the sliding part 61 is in the first position, the transmission part 4 and the transmission hole 80 are separated, and the rotation of the lock cylinder shaft 2 will not drive the actuating part 3, thus achieving a "disengaged" state between the lock cylinder shaft 2 and the actuating part 3. When the sliding part 61 is in the second position, the sliding part 61 pushes against the transmission part 4, causing part of the transmission part 4 to be exposed in the connecting groove 901 and connected to the transmission hole 80. The rotation of the lock cylinder shaft 2 can drive the actuating part 3 to rotate synchronously through the transmission part 4, thus achieving a "engaged" state. The above method ensures accurate and reliable control of whether the intelligent lock cylinder can drive the actuating part 3 by external torque. Secondly, the combined structure of the sliding member 61, the connecting hole 90, the transmission member 4, and the transmission hole 80 is relatively simple, reducing the complex components and connections inside the smart lock cylinder. This simple structural design reduces manufacturing difficulty and cost, while also reducing the probability of failure and improving the stability and reliability of the smart lock cylinder. The sliding member 61 slides axially within the connecting hole 90, with a clear movement trajectory that is not easily affected by external interference. The transmission member 4 is connected to the transmission hole 80 under the push of the sliding member 61, and the connection method is stable and reliable, ensuring smooth power transmission between the lock cylinder shaft 2 and the actuating member 3, thus improving the overall operational stability of the smart lock cylinder.
[0053] like Figure 2 , Figure 3 and Figure 5As shown, in one embodiment, the sidewall of the sliding member 61 is formed with a pushing slope 611; when the lock core shaft 2 moves from the first position to the second position, the pushing slope 611 can move relative to the transmission member 4 and push against the transmission member 4. With this configuration, firstly, during the movement of the sliding member 61 from the first position to the second position, the pushing slope 611 on the side wall of the sliding member 61 moves relative to the transmission member 4 and pushes against the transmission member 4. This pushing method ensures that the force is evenly applied to the transmission member 4, avoiding deformation or damage to the transmission member 4 due to excessive local force, and ensuring the smoothness of the transmission process. For example, in the frequent unlocking and locking operations of the smart lock cylinder, a smooth transmission process can ensure the long-term stable operation of the lock cylinder and reduce the probability of failure. Furthermore, the design of the pushing slope 611 makes the movement trajectory of the transmission member 4 more controllable. When the sliding member 61 moves, the pushing slope 611 applies force to the transmission member 4 at a predetermined angle and direction, enabling the transmission member 4 to move accurately to the designated position and achieve a reliable connection with the transmission hole 80. This ensures that when the lock cylinder shaft 2 rotates, it can smoothly drive the actuating member 3 to rotate synchronously, improving the reliability of the transmission. Secondly, by using the pushing slope 611 to push the transmission component 4, there is no need to set up an additional complex transmission mechanism, making the internal structure of the smart lock cylinder more compact and the layout between the components more reasonable, reducing space occupation, which is conducive to the miniaturization design of the smart lock cylinder, making it easy to install in door locks of different specifications and meet diverse market demands. Moreover, in a limited space, the design of the pushing slope 611 can make full use of the space of the side wall of the sliding component 61, realizing the transmission function without increasing the volume too much, improving the space utilization rate, and making the overall structure of the smart lock cylinder more compact and efficient.
[0054] like Figure 2 and Figure 3As shown, in one embodiment, the driving element 5 is an electromagnet 51, and the sliding element 61 passes through the electromagnet 51. The electromagnet 51 can magnetically drive the sliding element 61 to move axially. With this configuration, firstly, the electromagnet 51, as the driving element 5, can rapidly generate a magnetic field upon energization, thereby quickly applying magnetic force to the sliding element 61 and driving it to move axially. Compared to some mechanical driving methods, the response time of the electromagnet 51 is extremely short, enabling the sliding element 61 to move from a first position to a second position in a very short time. This achieves the transmission connection or separation between the lock cylinder shaft 2 and the actuating element 3, greatly improving the unlocking and locking speed of the smart lock cylinder and enhancing the user experience. Secondly, the structure of the electromagnet 51 driving the sliding member 61 is relatively simple, eliminating the need for complex mechanical transmission mechanisms such as gears and chains. This not only reduces the number of components inside the smart lock cylinder, lowering manufacturing difficulty and cost, but also makes the entire lock cylinder structure more compact, facilitating installation in door locks of different sizes. It is especially suitable for applications with high space requirements. Furthermore, the more compact layout of the electromagnet 51 and the sliding member 61 allows for full utilization of the internal space of the smart lock cylinder, providing more room for the installation and functional implementation of other components, which is beneficial for the miniaturization and integration design of the smart lock cylinder. Thirdly, the electromagnet 51 drives the sliding member 61 to move via magnetic force. During the movement, there is no direct friction or collision between mechanical parts, resulting in extremely low noise. Compared to some mechanical drive methods, such as gear transmission and cam mechanisms, the smart lock cylinder driven by the electromagnet 51 is quieter during operation and less prone to noise interference.
[0055] It should be noted that in some embodiments, the driving component 5 may also be, but is not limited to, an electric telescopic rod or a gear and rack transmission structure, etc., whichever is selected according to actual needs, and no single limitation is made here.
[0056] like Figure 2 , Figure 3 and Figure 5As shown, in one embodiment, the sliding member 61 includes a permanent magnet 613 and a pusher sleeve 612. The permanent magnet 613 passes through the electromagnet 51, and the pusher sleeve 612 is connected to one end of the permanent magnet 613. The pusher sleeve 612 is at least partially disposed in the connecting hole 90, and the pusher slope 611 is formed on the side wall of the pusher sleeve 612. With this configuration, firstly, the permanent magnet 613 is inserted into the electromagnet 51. When the electromagnet 51 is energized, it can quickly generate a magnetic interaction with the permanent magnet 613. Since the permanent magnet 613 itself has a stable magnetic field, in combination with the magnetic field generated by the electromagnet 51, it can quickly and powerfully drive the sliding member 61 to move along the axial direction, achieving rapid response and precise driving, meeting the needs of the smart lock cylinder for rapid unlocking and locking. Furthermore, the magnetic field characteristics of the permanent magnet 613 enable it to maintain a relatively stable driving force during its interaction with the electromagnet 51. Even after long-term use or under different environmental conditions, the magnetic field strength of the permanent magnet 613 changes little, ensuring the stability of the sliding member 61's drive and reducing malfunctions and misoperations caused by unstable driving force. Secondly, as a component that directly contacts the transmission component 4, the push bushing 612 can prevent the permanent magnet 613 from directly contacting the transmission component 4, thereby preventing damage to the permanent magnet 613. The push bushing 612 needs to have good wear resistance. High-strength and wear-resistant materials such as stainless steel and engineering plastics can be selected to make the push bushing 612 to ensure that the surface of the push bushing 612 will not be excessively worn due to friction during long-term use, thereby ensuring the normal realization of the pushing function and extending the service life of the sliding component 61. Thirdly, the permanent magnet 613 and the push bushing 612 are combined to form the sliding component 61. The permanent magnet 613 is responsible for magnetically driving the electromagnet 51, while the push bushing 612 is used to achieve the pushing function with the transmission component 4. This structural layout makes the sliding component 61 highly integrated, realizing the coordinated work of multiple functions in a limited space, while ensuring the compactness of the structure and facilitating the miniaturization design of the smart lock cylinder. Furthermore, as two relatively independent modules, the permanent magnet 613 and the push bushing 612 are easy to produce and assemble. During the manufacturing process, the permanent magnet 613 and the push bushing 612 can be processed and tested separately, improving production efficiency and quality. During maintenance and replacement, the problematic module can be handled separately, reducing maintenance costs.
[0057] like Figure 2 , Figure 3 and Figure 4As shown, in one embodiment, the transmission component 4 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 movable component 6, rapidly moving to the appropriate position and engaging with the actuating hole of the actuating component 3. During legal unlocking, this rapid transmission response allows the user to quickly drive the actuating component 3 to unlock after rotating the lock cylinder shaft 2, reducing unlocking waiting time and improving unlocking efficiency and smoothness. Second, the ball bearing typically has a small volume, occupying minimal space within the smart lock cylinder. This allows for a more compact overall lock cylinder structure, facilitating installation and use in situations where installation space is limited. Third, the ball bearing is spherical, possessing the characteristic of free rolling in all directions. When the movable component 6 pushes the ball bearing, the ball bearing can automatically adjust its angle and direction according to the position and shape of the actuating component 3, finding the optimal engagement position. Regardless of how the actuating component 3 changes its posture in space, the ball bearing can adapt to this change through its own rolling, ensuring reliable engagement.
[0058] It should be noted that in some other embodiments, the transmission component 4 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.
[0059] like Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment, the smart lock cylinder further includes a reset elastic element 9, which is disposed on the movable element 6. When the driving element 5 is de-energized, the reset elastic element 9 is used to elastically drive the movable element 6 to move to the first position. With this configuration, when the driving element 5 is de-energized, the reset elastic element 9 can drive the movable element 6 from the second position to the first position by its own elastic force. This feature allows the smart lock cylinder to automatically return to its initial state after each unlocking or locking operation without additional manual operation or complex control procedures. Furthermore, the reset elastic element 9 ensures that the movable element 6 returns to the first position, separating the transmission element 4 from the transmission hole 80, preventing the lock cylinder shaft 2 from rotating and driving the actuating element 3. This design effectively prevents the risk of illegal unlocking caused by the movable element 6 remaining in the second position due to unexpected situations (such as circuit failure or misoperation).
[0060] In one embodiment, the reset elastic element 9 is a spring 91.
[0061] It should be noted that in some other embodiments, the reset elastic element 9 may also be, but is not limited to, elastic rubber or elastic silicone, etc., and can be selected according to actual needs. It is not a unique limitation here.
[0062] like Figure 4 and Figure 5As shown, in one embodiment, a synchronously rotating toggle block 32 is provided on one side of the toggle member 3, and the toggle block 32 is used to be connected to the locking tongue drive.
[0063] Example 2 Please see Figures 6 to 10 The main difference between this embodiment and Embodiment 1 lies in the specific structures of the driving component 5 and the movable component 6. Specifically, in this embodiment, the movable component 6 is a rotating wheel 62, which is rotatably disposed within the connecting hole 90. The peripheral sidewall of the rotating wheel 62 is provided with a clearance portion 621 and a push-out portion 622. When the rotating wheel 62 rotates to the first position, please refer to... Figure 7 The clearance part 621 abuts against the transmission component 4. The transmission component 4 is located in the connecting groove 901 and is separated from the transmission hole 80. When the lock core shaft 2 rotates, the actuating component 3 remains stationary. When the rotating wheel 62 rotates to the second position, please refer to the following for details. Figure 8 The push-out part 622 abuts against the transmission member 4, pushing the transmission member 4 so that part of the transmission member 4 is exposed in the connecting groove 901 and connected to the transmission hole 80. When the lock cylinder shaft 2 rotates, it can drive the actuating member 3 to rotate synchronously through the transmission member 4. Thus, firstly, by rotating the rotating wheel 62 in the connecting hole 90, the avoidance part 621 and the push-out part 622 provided on its peripheral sidewall can accurately switch between two working states; secondly, the rotating wheel 62 is set in the connecting hole 90, making full use of the space of the connecting hole 90, making the internal structure of the smart lock cylinder more compact. This compact design is conducive to the miniaturization of the smart lock cylinder, making it easy to install in door locks of different sizes, especially suitable for occasions with high space requirements; thirdly, the rotating wheel 62 integrates the avoidance part 621 and the push-out part 622 into one unit, and the function switching between transmission and separation can be realized through a simple rotation action, reducing the use of additional parts and improving the efficiency of the components. The high degree of integration not only reduces the manufacturing cost of the smart lock cylinder but also simplifies the installation and maintenance process. Finally, the rotating wheel 62 uses the avoidance part 621 and the push-out part 622 to precisely switch between transmission and separation states. Its structural design and movement mode are simple and direct. During the rotation of the rotating wheel 62, only a small frictional force and inertial force need to be overcome to complete the state transition, and the driving power consumption of the rotating wheel 62 is significantly reduced. In addition, the rolling contact transmission mode between the rotating wheel 62 and the transmission component 4 has low friction, which reduces the energy loss caused by friction. When driving the rotating wheel 62 to rotate, only a small driving force needs to be provided to overcome the rolling friction force. Compared with sliding friction transmission, it can significantly reduce the driving power consumption.
[0064] like Figure 7 and Figure 8 As shown, in one embodiment, the rotating wheel 62 is provided with a plurality of hollowed-out portions 623 for weight reduction, thereby reducing the amount of work required to drive the rotating wheel 62 to rotate and making the rotating wheel easier to start.
[0065] like Figure 6 As shown, in one embodiment, the second end of the lock cylinder 2 is sleeved on the outside of the first end of the actuating member 3. The first end of the actuating member 3 is provided with a connecting hole 90, and the second end of the lock cylinder 2 is provided with a transmission hole 80.
[0066] like Figure 6 As shown, in one embodiment, the lock cylinder shaft 2 includes a shaft body 21 and a rotating sleeve 22. The rotating sleeve 22 is connected to one end of the shaft body 21, and the shaft body 21 and the rotating sleeve 22 can rotate synchronously. The second end of the lock cylinder shaft 2 is the rotating sleeve 22, and the aforementioned transmission hole 80 is provided inside the rotating sleeve 22.
[0067] In another embodiment, the first end of the actuating member 3 is sleeved on the outside of the second end of the lock cylinder 2, the first end of the actuating member 3 is provided with a transmission hole 80, and the second end of the lock cylinder 2 is provided with a connection hole 90.
[0068] In one embodiment, the drive component 5 is a coreless motor 52. It is understood that, compared to coreless motors, ordinary motors exhibit a significant cogging effect. Cogging force refers to a phenomenon caused by the attraction between the motor core and the permanent magnet; the direction of this force is either the same as or opposite to the direction of motor movement. In actual operation, the cogging effect becomes apparent when the motor moves on the magnetic track. Specifically, when rotating the motor shaft, the shaft tends to remain in certain specific positions. To move the shaft away from these positions and stabilize it in other positions, greater resistance needs to be overcome. The cogging effect causes the resistance experienced by the motor to vary depending on the position when starting. A similar situation occurs when resetting under the action of the torsion spring. Because the tightness of the torsion spring varies each time it operates, when the torsion spring releases its elastic force to reset the eccentric wheel, the sum of the remaining elastic potential energy and kinetic energy of the eccentric wheel-torsion spring system is not a fixed value when passing through the same position. This change is mainly caused by the change in kinetic energy. For coreless motors without cogging effect and with minimal shaft resistance, the above changes do not have a negative impact. Simply aligning the initial position of the eccentric wheel with the opening in the rotor, ensuring the balls fall into the groove of the eccentric wheel in the initial state, guarantees normal reset. However, for motors with cogging effects, if the sum of elastic potential energy and kinetic energy is insufficient to overcome the resistance generated by the cogging effect in the final stroke of the reset process, reset may fail. To avoid such reset failures, a preferred method is to add a limit switch to the eccentric wheel to ensure that its entire stroke does not cross the region with significant cogging effects. It should be noted that the aforementioned stroke refers to a segment of an arc, and the region refers to a part of a circular ring. On the circular ring, regions with and without cogging effects are usually alternately distributed. The position is defined as the position pointed to by the terminal side after determining the zero position and given an arbitrary angle θ.
[0069] It should be noted that the drive component 5 can also be a motor that can provide torque, which is commonly used by those skilled in the art. There is no single limitation here, and it can be selected according to actual needs.
[0070] It should be noted that, as Figure 13 As shown, in some other embodiments, the drive unit 5 may also be, but is not limited to, a servo motor or a geared motor, etc., and can be selected according to actual needs. There is no unique limitation here.
[0071] like Figure 9 and Figure 10 As shown, in one embodiment, the smart lock cylinder further includes a reset elastic element 9, which is disposed on the movable element 6. When the drive element 5 is de-energized, the reset elastic element 9 is used to forcefully drive the movable element 6 to rotate to the first position. With this configuration, when the drive element 5 is de-energized, the reset elastic element 9 can drive the movable element 6 from the second position to the first position by its own elastic force. This feature allows the smart lock cylinder to automatically return to its initial state after each unlocking or locking operation without additional manual operation or complex control procedures. Furthermore, the reset elastic element 9 ensures that the movable element 6 returns to the first position, separating the transmission element 4 from the transmission hole 80, preventing the lock cylinder shaft 2 from rotating and driving the actuating element 3. This design effectively prevents the risk of illegal unlocking caused by the movable element 6 remaining in the second position due to unexpected situations (such as circuit failure or misoperation).
[0072] In one embodiment, the reset elastic element 9 is a first torsion spring 92.
[0073] Example 3 It is understandable that when the driving component 5 is energized and the driving transmission component 4 is partially exposed in the connecting groove 901 and connected to the transmission hole 80, the actuating component 3 will be subjected to an external force (such as an external force from the tongue). This external force will be transmitted to the transmission component 4, causing the transmission component 4 to interfere with the connecting groove 901, the moving component 6 and the transmission hole 80 respectively. When the driving component 5 is de-energized, due to the existence of the above interference, the transmission component 4 will have difficulty retracting relative to the connecting groove 901 to the position separated from the transmission hole 80.
[0074] Please see Figure 11To address the aforementioned issues, the main difference between this embodiment and Embodiments 1 and 2 lies in the following: at least two transmission components 4 and at least two connecting slots 901 are provided, with at least two transmission components 4 correspondingly and movably disposed within at least two connecting slots 901. Thus, by providing at least two transmission components 4, each correspondingly and movably disposed within at least two connecting slots 901, when the actuating component 3 is subjected to an external force (such as a force from the tongue), this force is distributed and transmitted to multiple transmission components 4. The force borne by each transmission component 4 is significantly reduced compared to the case of a single transmission component 4. In the design of a single transmission component 4, the external force is concentrated on one transmission component 4, causing significant interference between it and the connecting slot 901, the movable component 6, and the transmission hole 80, making it difficult for the transmission component 4 to retract after the driving component 5 is de-energized. However, with the design of multiple transmission components 4, due to the distributed force, the interference between each transmission component 4 and surrounding components is reduced, decreasing the jamming phenomenon caused by interference and improving the smoothness of the transmission component 4's retraction. For example, in a smart lock cylinder, when the latch is impacted and generates force, the two transmission components 4 share the force, which avoids excessive squeezing of a single transmission component 4 with components such as the connecting groove 901 due to excessive force, and makes it easier for the drive component 5 to return to its original position after power is cut off.
[0075] In some embodiments, the number of transmission components 4 may be, but is not limited to, 2, 3, 4, and 5, and the number of connecting slots 901 shall not be less than the number of transmission components 4. The number can be set according to actual needs and is not limited here.
[0076] Example 4 It is understandable that when the driving component 5 is energized and the driving transmission component 4 is partially exposed in the connecting groove 901 and connected to the transmission hole 80, the actuating component 3 will be subjected to an external force (such as an external force from the tongue). This external force will be transmitted to the transmission component 4, causing the transmission component 4 to interfere with the connecting groove 901, the moving component 6 and the transmission hole 80 respectively. When the driving component 5 is de-energized, due to the existence of the above interference, the transmission component 4 will have difficulty retracting relative to the connecting groove 901 to the position separated from the transmission hole 80.
[0077] Please see Figure 12To solve the above problems, the main difference between this embodiment and Embodiments 1 and 2 is that a second torsion spring 30 is connected between the shaft 21 and the rotating sleeve 22; when the lock cylinder shaft 2 is rotated, the second torsion spring 30 connects the shaft 21 and the rotating sleeve 22, and the relative positions of the shaft 21 and the rotating sleeve 22 are fixed and rotate synchronously; when the lock cylinder shaft 2 is released, due to the elastic force of the second torsion spring 30, the rotating sleeve 22 will rotate slightly relative to the shaft 21. Thus, the second torsion spring 30 connects the shaft 21 and the rotating sleeve 22. When the lock cylinder shaft 2 is rotated, it can ensure that the relative position of the shaft 21 and the rotating sleeve 22 is fixed and rotates synchronously, so that the lock cylinder shaft 2 is operated as a whole, which conforms to normal usage logic. When the lock cylinder shaft 2 is released, the slight rotation of the rotating sleeve 22 provides a buffer and adjustment mechanism. Due to the presence of the second torsion spring 30, the rotating sleeve 22 can adaptively adjust according to the external force and the state of the internal transmission component 4. When the external force causes the transmission component 4 to have an interference tendency, the elastic force of the second torsion spring 30 can play a timely role, and eliminate or reduce the interference through the relative rotation of the rotating sleeve 22.
[0078] In one embodiment, the rotating sleeve 22 has two slots 221, and the second torsion spring 30 is respectively inserted into the two slots 221. The main body of the second torsion spring 30 is sleeved on the shaft 21.
[0079] 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.
