Description

Technical Field

[0001] This utility model belongs to the field of smart lock technology, specifically relating to a smart lock cylinder that supports mechanical unlocking. Background Technology

[0002] Currently, the structure of smart locks for entry doors is quite complex. For entry doors using standard lock bodies, compatible smart locks include a front panel, connectors, transmission components, and a back panel. The front and back panels need to be securely fixed to the door leaf via connectors, and a complex electrical connection usually needs to be established 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 many unresolved problems: The aforementioned complex smart locks suffer from two fundamental flaws: First, compatibility issues: existing smart locks have poor door adaptability, generally unable to upgrade existing mechanical door locks to smart locks. This limits the widespread adoption of smart locks, preventing many users from enjoying their installation and convenience. Second, power supply issues: existing smart locks rely primarily on batteries or external power sources, requiring consideration of power availability and environmental factors, making them inconvenient for users and also resulting in high costs and environmental pollution.

[0003] Because existing smart locks cannot be unlocked electronically once the power is off, some existing smart locks are equipped with mechanical unlocking mechanisms, such as mechanical keys or mechanical combination dials, to address this issue and enable emergency unlocking when the electronic components run out of power or are damaged. However, these mechanisms still have the following drawbacks: Smart locks frequently run out of power, while mechanical keys are used more often. Smart locks that use mechanical keys for emergency unlocking have problems such as insufficient lock cylinder security level, large key size, and cumbersome key insertion operation. Smart locks that use other mechanical emergency unlocking methods, especially some smart locks that use mechanical combination dials, also have serious security defects. After the user enters the password to unlock, the combination dial cannot be randomly scrambled, and the mechanical combination is easily leaked. The mechanical and electronic unlocking mechanisms of existing smart locks do not have intelligent linkage. In other words, mechanical key unlocking is similar to that of a conventional mechanical lock, and the lock can be opened as long as the key is compatible. Mechanical key unlocking and key duplication do not leave electronic records, which can easily lead to the abuse of mechanical keys and significantly reduce the security of smart locks. Utility Model Content

[0004] The purpose of this invention is to disclose a smart lock cylinder that supports mechanical unlocking, addressing the problems of complex structure, inconvenient installation, poor compatibility, and reliance on external power supply found in existing smart lock cylinders. Through highly integrated design, self-generating technology, and intelligent security control mechanisms, this smart lock cylinder achieves high compatibility and high security without requiring external power or a built-in battery. Furthermore, this smart lock cylinder combines intelligently linked electronic and mechanical unlocking functions. It can unlock the lock using a less frequently used mechanical key when the electronic components malfunction, and when the electronic components are functioning normally, it records electronic and mechanical unlocking information in an electronic log, preventing the misuse of mechanical keys and thus ensuring the security of the smart lock cylinder.

[0005] To achieve the above objectives, this utility model discloses an intelligent lock cylinder that supports mechanical unlocking, comprising: Lock cylinder body; Lock cylinder shaft, which is rotatably mounted on the lock cylinder body; A toggle element is rotatably mounted on the lock cylinder body. The toggle element is used for transmission connection with the lock tongue. The axially corresponding ends of the toggle element and the lock cylinder shaft are rotatably sleeved and connected. The grip assembly includes a grip and a mechanical lock cylinder for unlocking with a mechanical key. The grip is rotatably disposed at one axial end of the lock cylinder body, and the mechanical lock cylinder is coaxially and synchronously disposed within the grip. Both the grip and the mechanical lock cylinder are connected to the lock cylinder shaft for transmission. A drive assembly is installed on the lock cylinder body. The drive assembly includes a generator, a circuit board, and a drive component. The generator is driven by the lock cylinder shaft, and both the generator and the drive component are electrically connected to the circuit board. The transmission assembly is installed in the mounting cavity of the actuating element and can be connected to the driving element, the actuating element and the lock cylinder shaft. The handle is connected to the end of the actuating element away from the lock cylinder shaft; When the electronic lock is unlocked, the handle drives the lock cylinder shaft to rotate, which drives the generator to generate electricity to power the circuit board and drive components. When the circuit board is powered on, it generates control signals to control the start and stop of the drive components, so that the toggle component and the lock cylinder shaft can rotate synchronously or relative to each other via the transmission assembly. When mechanically unlocking, the mechanical key drives the lock cylinder shaft to move axially and rotate via the mechanical lock cylinder, so as to drive the actuating element to rotate synchronously via the transmission component.

[0006] As an optional implementation, the lock cylinder shaft includes a shaft body and a rotating sleeve that can rotate synchronously. One end of the shaft body is connected to the handle and the mechanical lock cylinder, and the shaft body is connected to the generator and the transmission assembly. The other end of the shaft body is axially movable and connected to the rotating sleeve. The rotating sleeve is rotatably sleeved and connected to the axially corresponding end of the actuating element.

[0007] As an optional implementation, the mechanical lock cylinder is connected to the shaft via a transmission block. The transmission block is sleeved and connected to the axially corresponding end of the mechanical lock cylinder. The side wall of the mechanical lock cylinder has an axially extending inclined groove, and the side wall of the transmission block has a transmission column passing through the inclined groove.

[0008] As an optional implementation, the shaft and the generator are connected by a reducer. The reducer is synchronously rotatable and sleeved on the shaft. A first elastic element is provided between the reducer and the inner cavity of the handle and sleeved on the shaft. When there is no unlocking action, the first elastic element is in a naturally extended state.

[0009] As an optional implementation, the mechanical lock cylinder has a limiting post and a limiting groove at the axial end near the shaft. The limiting groove is set at the end of the inclined groove near the shaft. The two ends of the limiting post abut against the inner wall of the handle and the mechanical lock cylinder, respectively. A second elastic element is provided between the limiting post and the handle. When the mechanical lock is not mechanically unlocked, the limiting post is set at the end of the inclined groove away from the shaft, and the second elastic element is in a compressed state.

[0010] As an optional implementation, in the axially corresponding ends of the actuating member and the rotating sleeve, the inner wall of the hole fitted inside is provided with a through connecting groove, and the mounting cavity communicates with the connecting groove. The transmission assembly includes a transmission component and a movable component. The transmission component is movably disposed in the connecting groove, and the movable component is connected to the driving component for transmission. The driving component can drive the movable component to push against the transmission component, so that part of the transmission component is exposed in the connecting groove and connected to the actuating component and the rotating sleeve which are sleeved on the outside.

[0011] As an optional implementation, the inner wall of the actuating member and the rotating sleeve is provided with multiple locking positions. When the movable member pushes the transmission member part exposed in the connecting groove, the transmission member is connected to any of the locking positions.

[0012] As an optional implementation, the rotating sleeve is fitted inside the actuating member, the hole wall of the rotating sleeve is provided with a through first connecting groove, and the inner wall of the actuating member is provided with a plurality of second locking positions. The movable component includes a sliding component, which is located inside the rotating sleeve. When the drive component is energized and when the shaft moves axially, the sliding component can be driven to slide axially to push the transmission component part exposed in the first connecting groove and connected to any of the first locking positions, so that the rotation of the lock core shaft can drive the actuating component to rotate synchronously through the transmission component.

[0013] As an optional implementation, the driving component is an electromagnet, and the sliding component includes a permanent magnet and a pusher sleeve. The permanent magnet passes through the electromagnet, and the pusher sleeve is connected to one end of the permanent magnet. The pusher sleeve is at least partially disposed inside the rotating sleeve. The side wall of the pusher sleeve forms a pusher slope. The axial movement of the pusher slope can push the transmission component part exposed in the first connecting groove and connected to any second locking position. When the shaft moves axially, it can push the sliding component to move axially.

[0014] As an optional implementation, the permanent magnet is fitted with a first reset member, which is located between the electromagnet and the push bushing. In the initial state, the first reset member is in a naturally elongated state.

[0015] As an optional implementation, the rotating sleeve is fitted over the actuating member, the inner wall of the rotating sleeve is provided with multiple locking positions, and the hole wall of the actuating member is provided with a through second connecting groove. The driving component is a hollow cup motor, and the moving component includes a rotating wheel. The rotating wheel is rotatably disposed in the mounting cavity and corresponds to the second connecting groove. The peripheral sidewall of the rotating wheel is provided with a concave part and a convex part. The rotation of the rotating wheel can push the transmission component part exposed in the second connecting groove through the convex part and connect with any of the first locking positions, so that the rotation of the lock core shaft can drive the actuating component to rotate synchronously through the transmission component.

[0016] As an optional implementation, a second reset member is provided between the rotating wheel and the inner wall of the actuating member shaft end. In the initial state, the second reset member is in a naturally extended state.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) Both the mechanical unlocking mechanism and the electronic unlocking mechanism of this utility model are integrated into the main body of the lock cylinder, which highly integrates the functions of the smart lock cylinder 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 the production cost and installation difficulty. For electronic unlocking, the smart lock cylinder generates electricity by capturing the energy of the user rotating the lock cylinder shaft, thereby realizing communication, authentication and unlocking control. Unlocking verification can be completed through a mobile APP or other authenticators, and the unlocking action itself is completed by the power provided by the user. This self-generating design frees the smart lock cylinder from dependence on external power sources. Without using batteries or energy storage devices with liquid electrolytes, it realizes the functions of a smart lock, solving the problems of complex structure, inconvenient installation and need for regular battery replacement / charging of existing smart locks. For mechanical unlocking, unlocking can be achieved by installing a conventional mechanical lock cylinder in the handle and driving the lock cylinder shaft. There is no need to design a separate mechanical transmission mechanism. The structure is simple and easy to install. Furthermore, existing lock-related components do not require adaptation or modification for this smart lock cylinder. This smart lock cylinder allows users to directly replace their mechanical locks with this smart lock, which combines electronic and mechanical unlocking functions, without changing any other components (such as the door or lock body) or any user habits. This eliminates the incompatibility issues with doors and lock bodies, and the need for regular charging / battery replacements present in existing smart locks. At the same time, cracking a smart lock, which uses electronic circuits and modern cryptographic algorithms as its core authentication method, is significantly more difficult than cracking a traditional mechanical lock, resulting in a substantial increase in security.

[0018] (2) Mechanical keys are generally used when the electronic unlocking mechanism malfunctions. Since the electronic unlocking mechanism does not require charging / battery replacement and adopts self-generating technology, it has a long service life. Mechanical keys are used less frequently, and electronic unlocking is the primary method, which can ensure security. Furthermore, when the electronic part is functioning normally, the mechanical unlocking mechanism and the electronic unlocking mechanism are intelligently linked. Any unlocking operation can be recorded in the form of an electronic log and can be traced, which can prevent the abuse of mechanical keys.

[0019] (3) When the electronic unlocking authentication fails, the circuit board de-energizes the drive component and puts it in a stopped state. At this time, the lock cylinder shaft rotates freely and cannot drive the actuating component, thus preventing violent unlocking behavior. When the authentication is successful, the circuit board energizes the drive component and puts it in a start state. The drive component drives the transmission component to move so that the rotation of the lock cylinder shaft can synchronously drive the actuating component to rotate, realizing normal unlocking operation. This intelligent control method ensures that only authorized users can perform unlocking operations, and the unlocking action is consistent with the traditional mechanical lock cylinder. 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.

[0020] (4) Regarding mechanical unlocking, the mechanical lock cylinder can use readily available telescopic lock cylinders on the market, achieving a security level of C, and can be unlocked using standard-sized keys, exhibiting good compatibility and security. Furthermore, according to user needs, the mechanical key can be made impossible to remove once used, effectively curbing the misuse of mechanical keys. Attached Figure Description

[0029] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0030] Example 1 Please see Figure 1-5 This embodiment provides an intelligent lock cylinder that supports mechanical unlocking, including a lock cylinder body 1, a lock cylinder shaft 2, a toggle component 3, a handle assembly 4, a drive assembly 5, and a transmission assembly 6.

[0031] The lock cylinder shaft 2 is rotatably mounted on the lock cylinder body 1, and the actuating element 3 is rotatably mounted on the lock cylinder body 1. The actuating element 3 is used for transmission connection with the lock tongue, and the actuating element 3 and the axially corresponding ends of the lock cylinder shaft 2 are rotatably sleeved and connected. Specifically, the first axial end of the actuating element 3 and the second axial end of the lock cylinder shaft 2 are rotatably sleeved and connected, so that the actuating element 3 and the lock cylinder shaft 2 can rotate synchronously or relative to each other.

[0032] The grip assembly 4 includes a grip 41 and a mechanical lock cylinder 42 for mechanical key unlocking. The grip 41 is rotatably mounted on one axial end of the lock cylinder body 1. The mechanical lock cylinder 42 is coaxially and synchronously rotatably mounted within the grip 41. Both the grip 41 and the mechanical lock cylinder 42 are connected to the lock cylinder shaft 2 for transmission. The grip 41 is used for electronic unlocking. When unlocking electronically, rotating the grip 41 can drive the grip assembly 4 to rotate as a whole, and drive the lock cylinder shaft 2 to rotate synchronously. The mechanical lock cylinder 42 is used for mechanical unlocking. When unlocking mechanically, a suitable mechanical key is inserted into the mechanical lock cylinder 42 and rotated to drive the lock cylinder shaft 2 to move axially closer to the actuating member 3 and rotate.

[0033] A drive assembly 5 is installed on the lock cylinder body 1. The drive assembly 5 includes a generator 51, a circuit board 52, and a drive component 53. The generator 51 is driveably connected to the lock cylinder shaft 2, and both the generator 51 and the drive component 53 are electrically connected to the circuit board 52. Rotation of the lock cylinder shaft 2 drives the generator 51 to rotate and generate electricity, providing power to the circuit board 52 and the drive component 53. The drive component 53 is controlled by the circuit board 52 to operate. A transmission assembly 6 is installed in the mounting cavity 31 of the actuating component 3. The transmission assembly 6 is driveably connected to the drive component 53, the actuating component 3, and the lock cylinder shaft 2. During electronic unlocking, if the circuit board 52 controls the drive component 53 to drive the transmission assembly 6, the lock cylinder shaft 2 and the actuating component 3 can be linked through the transmission assembly 6, thereby causing the actuating component 3 to rotate through the rotation of the lock cylinder shaft 2. During mechanical unlocking, the axial movement and rotation of the lock cylinder shaft 2 can be linked to the actuating component 3 through the transmission assembly 6, thereby causing the actuating component 3 to rotate through the rotation of the lock cylinder shaft 2.

[0034] When the electronic lock is unlocked, the handle 41 drives the lock cylinder shaft 2 to rotate, which in turn drives the generator 51 to generate electricity to power the circuit board 52 and the drive unit 53. The circuit board 52, when energized, generates a control signal to control the start and stop of the drive unit 53, so that the actuating element 3 and the lock cylinder shaft 2 rotate synchronously or relative to each other via the transmission assembly 6. Specifically, when the handle 41 is rotated to drive the lock cylinder shaft 2 to generate electricity, if the authentication fails, the circuit board 52 de-energizes the drive unit 53, putting it in a stopped state. At this time, the lock cylinder shaft 2 spins idly and cannot drive the actuating element 3. When the handle 41 is rotated to drive the lock cylinder shaft 2 to generate electricity, if the authentication passes, the circuit board 52 energizes the drive unit 53, putting it in a driving state. The drive unit 53 drives the transmission assembly 6 to move, causing the lock cylinder shaft 2 and the actuating element 3 to move in tandem. At this time, the rotation of the lock cylinder shaft 2 can synchronously drive the rotation of the actuating element 3. When mechanically unlocking, the mechanical key drives the lock cylinder shaft 2 to move axially and rotate via the mechanical lock cylinder 42, so as to drive the actuating element 3 to rotate synchronously via the transmission assembly 6.

[0035] Based on the above structure, the working principle of the smart lock cylinder in this embodiment is as follows: When unlocking the door from inside the room, the user does 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 to achieve fast unlocking, which greatly saves the user's time and energy. It is especially suitable for quick entry and exit in emergency situations.

[0036] When electronic unlocking is performed from outside the room, under abnormal operation (i.e., when authentication fails), the drive component 53 is de-energized and in a stopped state, and the transmission component 6 does not move, so that the lock cylinder shaft 2 and the actuating component 3 are separated. At this time, turning 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 using the smart lock cylinder.

[0037] When electronic unlocking is performed outside the room, under normal operation (i.e., when authentication is successful), the drive unit 53 is powered on and in the start state. The drive unit 53 drives the transmission component 6 to move. At this time, rotating the lock cylinder shaft 2 outside the room will drive the actuating component 3 to rotate synchronously through the transmission component 6. The entire operation process is simple and efficient. The drive unit 53 responds quickly after being powered on, driving the transmission component 6 to move precisely into place. At this time, rotating the lock cylinder shaft 2 can quickly drive the actuating component 3 to rotate synchronously, thereby realizing the electronic unlocking operation. The whole process is smooth and natural, without any stuttering or delay, improving the user experience.

[0038] When mechanical unlocking is performed outside the room and the mechanical key is compatible, inserting and turning the mechanical key into the mechanical lock cylinder 42 will cause the lock cylinder shaft 2 to move and rotate axially toward the actuating element 3, thereby linking with the actuating element 3 to drive the actuating element 3 to rotate synchronously.

[0039] Based on this, the smart lock cylinder supporting mechanical unlocking in this embodiment has at least the following technical effects: (1) Both the mechanical unlocking mechanism and the electronic unlocking mechanism are integrated into the main body 1 of the lock cylinder, which highly integrates the functions of the smart lock cylinder 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 the production cost and installation difficulty. For electronic unlocking, the smart lock cylinder generates electricity by capturing the energy of the user rotating the lock cylinder shaft 2, thereby realizing communication, authentication and unlocking control. Unlocking verification can be completed through a mobile APP or other authenticators, and the unlocking action itself is completed by the power provided by the user. This self-generating design frees the smart lock cylinder from dependence on external power sources. Without using batteries or energy storage devices with liquid electrolytes, it realizes the functions of a smart lock, solving the problems of complex structure, inconvenient installation and need for regular battery replacement / charging of existing smart locks. For mechanical unlocking, unlocking can be achieved by installing a conventional mechanical lock cylinder in the handle and driving the lock cylinder shaft 2. There is no need to design a separate mechanical transmission mechanism, which is simple in structure and easy to install. Furthermore, existing lock-related components do not require adaptation or modification for this smart lock cylinder. This smart lock cylinder allows users to directly replace their mechanical locks with this smart lock, which combines electronic and mechanical unlocking functions, without changing any other components (such as the door or lock body) or any user habits. This eliminates the incompatibility issues with doors and lock bodies, and the need for regular charging / battery replacements present in existing smart locks. At the same time, cracking a smart lock, which uses electronic circuits and modern cryptographic algorithms as its core authentication method, is significantly more difficult than cracking a traditional mechanical lock, resulting in a substantial increase in security.

[0040] (2) Mechanical keys are generally used when the electronic unlocking mechanism malfunctions. Since the electronic unlocking mechanism does not require charging / battery replacement and uses self-generating technology, it has a long service life. Mechanical keys are used less frequently, and electronic unlocking is the primary method, which can ensure security. Furthermore, when the electronic unlocking mechanism is in normal use, the mechanical unlocking mechanism and the electronic unlocking mechanism are intelligently linked, and any unlocking operation can be recorded and traced, which can avoid the abuse of mechanical keys and the security problems caused by mechanical key unlocking.

[0041] (3) When the electronic unlocking authentication fails, the circuit board 52 de-energizes the drive component 53 and puts it in a stopped state. At this time, the lock cylinder shaft 2 rotates freely and cannot drive the toggle component 3, thus preventing violent unlocking behavior. When the authentication is successful, the circuit board 52 energizes the drive component 53 and puts it in a start state. The drive component 53 drives the transmission component 6 to move so that the rotation of the lock cylinder shaft 2 can synchronously drive the toggle component 3 to rotate, thus realizing normal unlocking operation. This intelligent control method ensures that only authorized users can perform unlocking operations, and the unlocking action is consistent with the traditional mechanical lock cylinder, so that users can enjoy the advantages of smart locks such as not needing to carry physical keys and high security without changing their unlocking habits.

[0042] (4) Regarding mechanical unlocking, the mechanical lock cylinder 42 can use readily available telescopic lock cylinders on the market, achieving a security level of C, and can be unlocked using standard-sized keys, exhibiting good compatibility and security. Furthermore, according to user needs, the mechanical key can be made impossible to remove once used, effectively curbing the misuse of mechanical keys.

[0043] The lock cylinder shaft 2 includes a shaft body 21 and a rotating sleeve 22 that can rotate synchronously. One end of the shaft body 21 is connected to the handle 41 and the mechanical lock cylinder 42, and the shaft body 21 can be connected to the generator 51 and the transmission assembly 6. The other end of the shaft body 21 is axially movable and connected to the rotating sleeve 22. The rotating sleeve 22 is rotatably sleeved and connected to the axially corresponding end of the actuating member 3.

[0044] One end of the shaft 21 is connected to the handle 41 so that when the handle 41 is rotated for electronic unlocking, the shaft 21 can rotate synchronously, thereby driving the generator 51 to generate electricity and supply power to the circuit board 52 and the drive unit 53. When the authentication is successful, the circuit board 52 controls the drive unit 53 to be energized to drive the transmission assembly 6 to move, so that the actuating element 3 is linked with the rotating sleeve 22, thereby using the rotation of the shaft 21 to drive the actuating element 3 to rotate synchronously to unlock; when the authentication fails, the circuit board 52 controls the drive unit 53 to be de-energized, the transmission assembly 6 does not move, the actuating element 3 and the rotating sleeve 22 are not linked, the lock cylinder shaft 2 rotates freely and cannot drive the actuating element 3 to rotate, and the lock cannot be unlocked.

[0045] One end of the shaft 21 is also connected to the mechanical lock cylinder 42 for transmission, so that when the appropriate mechanical key is used to turn it, the shaft 21 and the rotating sleeve 22 can be driven to rotate synchronously, and the shaft 21 can be moved toward the transmission assembly 6 to make the transmission assembly 6 move, so that the actuating element 3 and the rotating sleeve 22 are linked, and the rotation of the lock cylinder shaft 2 can drive the actuating element 3 to rotate synchronously to unlock.

[0046] For the mechanical unlocking mechanism in this embodiment, please refer to... Figure 6 and Figure 7The mechanical lock cylinder 42 is connected to the shaft 21 via a transmission block 43. The transmission block 43 is sleeved and connected to the axially corresponding end of the mechanical lock cylinder 42. The side wall of the mechanical lock cylinder 42 has an axially extending inclined groove 421, and the side wall of the transmission block 43 has a transmission post 431 passing through the inclined groove 421. One axial end of the transmission block 43 is located inside the mechanical lock cylinder 42, and the transmission block 43 and the mechanical lock cylinder 42 achieve transmission through the cooperation of the inclined groove 421 and the transmission post 431. The inclined groove 421 is axially set. In the initial state, the transmission column 431 is located at the end of the inclined groove 421 away from the shaft 21. A mechanical key is inserted into the mechanical lock cylinder 42. Turning the mechanical key can make the mechanical lock cylinder 42 rotate, thereby causing the transmission column 431 to move in the inclined groove 421 toward the shaft 21. Thus, the mechanical lock cylinder 42 drives the transmission block 43 to rotate synchronously and move axially away from the mechanical lock cylinder 42. The transmission block 43 drives the shaft 21 to rotate synchronously and move axially away from the mechanical lock cylinder 42, thereby unlocking the machine with the mechanical key.

[0047] The shaft 21 is connected to the generator 51 via a reducer 54. The reducer 54 is synchronously rotatably mounted on the shaft 21. A first elastic element 44 is provided between the reducer 54 and the inner cavity of the handle 41, and is mounted on the shaft 21. When there is no unlocking action, the first elastic element 44 is in a naturally extended state. When the shaft 21 rotates, it can drive the generator 51 to generate electricity through the reducer 54 and the gear set structure, which in turn supplies power to the circuit board 52. Thus, when the electronic unlocking function is normal, whether it is electronic or mechanical unlocking, the rotation of the shaft 21 can synchronously supply power to the circuit board 52 via the generator 51, so that the smart lock cylinder backend can completely record the unlocking operation information, making it convenient to view the person who unlocked the lock and the specific unlocking situation, and to trace the source in case of theft or other incidents, thus ensuring security.

[0048] The reducer 54 and the handle 41 are provided with a first elastic element 44. When the mechanical key unlocks, the shaft 21 moves axially toward the transmission assembly 6, which can compress the first elastic element 44. This allows the shaft 21 to be reset by the elasticity of the first elastic element 44 after unlocking, so that it can be used for the next unlocking.

[0049] Based on the above structure, the mechanical lock cylinder 42 has a limiting post 45 and a limiting groove 47 at its axial end near the shaft 21. The limiting groove 47 is set at one end of the inclined groove 421 near the shaft 21. The two axial ends of the limiting post 45 abut against the inner wall of the handle 41 and the mechanical lock cylinder 42, respectively. A second elastic element 46 is provided between the limiting post 45 and the handle 41. When not mechanically unlocked, the limiting post 45 is set at the end of the inclined groove 421 away from the shaft 21, and the second elastic element 46 is in a compressed state. In the initial state, the two axial ends of the limiting post 45 abut against the inner wall of the handle 41 and the mechanical lock cylinder 42, respectively, and the second elastic element 46 is in a compressed state. When mechanical unlocking is required, a mechanical key is inserted into the mechanical lock cylinder 42. Turning the mechanical key causes the mechanical lock cylinder 42 to rotate, thereby causing the transmission pin 431 to move towards the shaft 21 within the inclined groove 421. This allows the mechanical lock cylinder 42 to drive the transmission block 43 to rotate synchronously and move axially away from the mechanical lock cylinder 42, thus completing the mechanical unlocking. Simultaneously, the rotation of the mechanical lock cylinder 42 causes the limiting groove 47 to gradually approach the limiting pin 45. When the mechanical unlocking is completed, the positions of the limiting groove 47 and the limiting pin 45 correspond. The elasticity of the second elastic element 46 causes the limiting pin 45 to be stuck in the limiting groove 47, preventing the mechanical unlocking structure from resetting. This results in the door being in a normally open state. Furthermore, because the mechanical lock cylinder 42 cannot reset, the inserted mechanical key cannot be removed. At this point, personnel can be aware of the mechanical key unlocking situation, which makes it convenient to use software to retrieve the electronic log of the smart lock cylinder to trace the situation, and can warn those who attempt to unlock the lock privately, making them realize that once a mechanical key is used, physical and electronic records will inevitably be left behind.

[0050] Furthermore, in cases where the aforementioned mechanical unlocking structure cannot be reset, a structure that prevents the mechanical key from being removed can be installed. This not only records the mechanical unlocking information but also renders the mechanical key unusable, thus helping to prevent the misuse of the mechanical key.

[0051] The limiting post 45 and the second elastic element 46 are removable for use in different application scenarios.

[0052] Regarding the internal structure of the lock cylinder body 1 in this embodiment, the connection between the actuating member 3 and the rotating sleeve 22 can be such that one end of the actuating member 3 is sleeved on the outside of the other end of the rotating sleeve 22, or the other end of the rotating sleeve 22 is sleeved on the outside of one end of the actuating member 3.

[0053] For the electronic unlocking mechanism, the circuit board 52 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, causing the generator 51 to supply power to the circuit board 52. 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 energize the drive component 53, thereby enabling the user to rotate the toggle component 3 to perform operations such as retracting the latch and unlocking the deadbolt. If the authentication fails, the drive module does not energize the drive component 53, and the user can only rotate the lock cylinder shaft 2 to drive the generator 51 to generate electricity, but cannot rotate the toggle component 3.

[0054] In addition to the aforementioned grip assembly 4, the smart lock cylinder also includes a handle 7. The handle 7 is connected to the end of the actuating element 3 furthest from the lock cylinder shaft 2. Rotating the handle 7 causes the actuating element 3 to rotate synchronously. This configuration offers two advantages: First, the grip assembly 4 is connected to the lock cylinder shaft 2, and the handle 7 is connected to the end of the actuating element 3 furthest from the lock cylinder shaft 2. This design provides users with two different operating methods. Inside the room, users can directly rotate the handle 7 to cause the actuating element 3 to rotate synchronously, achieving quick unlocking without complicated procedures. Second, outside the room, users can rotate the grip 41 to cause the lock cylinder shaft 2 to rotate synchronously. Combined with the user authentication system, after successful authentication, users can unlock or lock the lock, or use a mechanical key to unlock. 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 grip assembly 4 and the handle 7 correspond to different operating logics. When unlocking electronically from outside the room, simply turning the grip 41 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.

[0055] like Figure 2-5As shown, in one embodiment, the drive component 53 is fixedly disposed within the mounting cavity 31. The smart lock cylinder also includes a brush structure 55, and the circuit board 52 is electrically connected to the drive component 53 through the brush structure 55. This arrangement not only ensures the stable operation of the drive component 53, but also has a compact structure that does not occupy too much extra space. During installation, no additional complex wiring and connection operations are required. Simply install the circuit board 52 and the drive component 53 correctly, and the electrical connection can be achieved using the brush structure 55. This simplifies the installation process, improves installation efficiency, and reduces installation costs. Within the limited mounting cavity 31 of the smart lock cylinder, this design can make full use of 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 facilitates installation in door locks of different sizes. In addition to power supply, the brush structure 55 also provides a reliable path for signal transmission between the circuit board 52 and the drive unit 53. The circuit board 52 can send control signals to the drive unit 53 through the brush structure 55, and the drive unit 53 can also feed back its own status information to the circuit board 52. For example, the circuit board 52 can send start or stop signals to the drive unit 53 through the brush structure 55 according to the user authentication result. The drive unit 53 can feed back its own rotation status, fault information, etc. to the circuit board 52, so that the circuit board 52 can make corresponding processing and adjustments, thereby improving the intelligence level and reliability of the smart lock cylinder.

[0056] It should be noted that the circuit board 52 can be, but is not limited to, PCB, PCBA, FPC, or FPCB, etc., and can be selected according to actual needs. There is no single limitation here.

[0057] For the transmission mechanism in this embodiment, please refer to... Figure 2-5 In the axially corresponding ends of the actuating member 3 and the rotating sleeve 22, the inner hole wall is provided with a through connecting groove, and the mounting cavity 31 communicates with the connecting groove; the transmission assembly 6 includes a transmission member 61 and a movable member 62. The transmission member 61 is movably disposed in the connecting groove, and the movable member 62 is connected to the driving member 53 so that the driving member 53 can drive the movable member 62 to push against the transmission member 61, so that part of the transmission member 61 is exposed in the connecting groove and connected to the actuating member 3 and the rotating sleeve 22.

[0058] When the electronic lock is unlocked, rotating the handle 41 drives the lock cylinder shaft 2 to rotate, thereby driving the generator 51 to generate electricity. If the authentication fails, the circuit board 52 de-energizes the drive component 53, causing it to be in a stopped state. At this time, the lock cylinder shaft 2 spins freely and cannot drive the actuating component 3. Rotating the handle 41 drives the lock cylinder shaft 2 to rotate, thereby driving the generator 51 to generate electricity. If the authentication passes, the circuit board 52 energizes the drive component 53, causing it to be in a driving state. The driving movable component 62 pushes against the transmission component 61, causing part of the transmission component 61 to protrude from the connecting groove and connect with the actuating component 3 and the rotating sleeve 22, thus linking the lock cylinder shaft 2 and the actuating component 3. At this time, the rotation of the lock cylinder shaft 2 can synchronously drive the rotation of the actuating component 3. When mechanically unlocking, the mechanical key drives the lock cylinder shaft 2 to move axially and rotate via the mechanical lock cylinder 42, thereby driving the movable part 62 to push the transmission part 61 part to protrude from the connecting groove, and connect with the actuating part 3 and the rotating sleeve 22, so that the lock cylinder shaft 2 and the actuating part 3 are linked, thereby driving the actuating part 3 to rotate synchronously.

[0059] The driving component 53 is located within the mounting cavity 31 of the actuating component 3, the movable component 62 is located at one end of the driving component 53, and the transmission component 61 is located within the connecting groove. This compact structural design reduces mutual interference between components. During long-term use, the components are less susceptible to external factors such as dust and moisture, thus reducing the probability of malfunctions and extending the service life of the smart lock cylinder. Furthermore, due to the small size of the movable component 62, the power consumption required to drive it is low. In a battery-free smart lock cylinder, the electrical energy generated by the smart lock cylinder's own power generation is sufficient to drive the movable component 62 to move accurately into place, enabling the transmission component 61 to maintain a stable transmission connection. This not only reduces the performance requirements of the driving component 53 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 53, movable component 62, and transmission component 61 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.

[0060] When the lock cylinder shaft 2 is rotated to drive the actuating element 3, the transmission element 61 can be precisely and easily aligned. Due to its reasonable structural design, the transmission element 61 can be smoothly partially exposed in the connecting groove under the push of the movable element 62 and tightly connected with the outer structure to form a stable transmission relationship. This precise transmission connection method avoids the problem of unlocking or locking failure due to inaccurate transmission, thus improving the reliability of the smart lock cylinder. Furthermore, the power consumption of driving the transmission element 61 and the movable element 62 is very low, and the power requirement of the generator 51 is low. Moreover, once the user's identity is verified, the energy demand of driving the transmission element 61 and the movable element 62 is simultaneously met, and the clutch between the lock cylinder shaft 2 and the actuating element 3 can be quickly engaged without complicated alignment. It features low energy demand and a good user experience.

[0061] The inner walls of the actuating member 3 and the rotating sleeve 22, which are fitted outwards, have multiple locking positions. When the movable member 62 pushes the transmission member 61, causing it to partially protrude from the connecting groove, the transmission member 61 connects with any of the locking positions. Thus, the multiple locking positions on the inner walls of the actuating member 3 and the rotating sleeve 22, when the movable member 62 pushes the transmission member 61, causing it to partially protrude from the connecting groove and connect with any of the locking positions, provide multiple connection options. Compared to a single locking position connection, multiple locking positions allow the selection of the nearest locking position based on the actual position and force of the transmission member 61, significantly reducing the circumferential travel required to establish transmission between the transmission member 61 and the locking position after certification. This effectively reduces the power consumption and time required for clutch engagement, providing a better user experience.

[0062] In this embodiment, the rotating sleeve 22 is fitted inside the actuating member 3. The hole wall of the rotating sleeve 22 is provided with a through first connecting groove 221. The inner wall of the actuating member 3 is provided with a plurality of second locking positions 33. The movable member (62) includes a sliding member. The sliding member is partially located inside the rotating sleeve 22. When the driving member (53) is energized and when the shaft 21 moves axially, the sliding member can be driven to slide axially to push the transmission member 61 part out of the first connecting groove 221 and connect with any of the second locking positions 33, so that the rotation of the lock core shaft (2) can drive the actuating member (3) to rotate synchronously through the transmission member 61. With this configuration, the movable part 62 adopts a sliding design and can slide along the axial direction, allowing for precise position switching. When the sliding part is in the first position, the transmission part 61 and the second locking position 33 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 is in the second position, the sliding part pushes against the transmission part 61, causing part of the transmission part 61 to be exposed in the first connecting groove 221 and connected to the second locking position 33. The rotation of the lock cylinder shaft 2 can drive the actuating part 3 to rotate synchronously through the transmission part 61, thus achieving a "engaged" state. The above method ensures accurate and reliable control of whether the external torque can drive the actuating part 3 by the intelligent lock cylinder.

[0063] When unlocking electronically, the sliding of the slider is achieved by the drive of the drive unit 53 when the authentication is successful. When unlocking mechanically, the sliding of the slider is achieved by the axial movement of the shaft 21.

[0064] In this embodiment, the driving component 53 is an electromagnet 531, and the sliding component includes a permanent magnet 621 and a pusher sleeve 622. The permanent magnet 621 passes through the electromagnet 531, and the pusher sleeve 622 is connected to one end of the permanent magnet 621. The pusher sleeve 622 is at least partially disposed within the rotating sleeve 22, and a pusher slope 623 is formed on the side wall of the pusher sleeve 622. The axial movement of the pusher slope 623 can push the transmission component 61 partially exposed in the first connecting groove 221 and connected to any of the second locking positions 33. When the shaft 21 moves axially, it can push the sliding component axially. During mechanical unlocking, the shaft 21 moves axially closer to the sliding component, so as to push the sliding component, i.e., the permanent magnet 621 and the pusher sleeve 622, away from the rotating sleeve 22 and move axially, thereby pushing the transmission component 61 to connect with the second locking position 33, so that the rotation of the lock cylinder shaft 2 can drive the actuating component 3 to rotate synchronously. When the electronic lock is unlocked, if the authentication is successful, the circuit board 52 controls the electromagnet 531 to be energized so that the permanent magnet 621 moves away from the rotating sleeve 22 axially and drives the push sleeve 622 to move synchronously, thereby pushing the transmission component 61 to connect with the second locking position 33, so that the rotation of the lock cylinder shaft 2 can drive the toggle component 3 to rotate synchronously.

[0065] During the axial movement of the sliding member, the pushing slope 623 on the side wall of the sliding member moves relative to the transmission member 61 and pushes against the transmission member 61. This pushing method allows the force to be applied evenly to the transmission member 61, avoiding deformation or damage to the transmission member 61 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 623 makes the movement trajectory of the transmission member 61 more controllable. When the sliding member moves, the pushing slope 623 applies a force to the transmission member 61 at a predetermined angle and direction, enabling the transmission member 61 to move accurately to the designated position and achieve a reliable connection with the second locking position 33. 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, the push-off ramp 623 is used to push the transmission component 61, eliminating the need for an additional complex transmission mechanism. This makes the internal structure of the smart lock cylinder more compact, the layout of each component more reasonable, and reduces space occupation. This is conducive to the miniaturization design of the smart lock cylinder, making it easier to install in door locks of different sizes and meet diverse market demands. Furthermore, within a limited space, the design of the push-off ramp 623 can make full use of the space on the side wall of the sliding component, achieving the transmission function without increasing the volume excessively, thus improving space utilization and making the overall structure of the smart lock cylinder more compact and efficient.

[0066] Electromagnet 531, acting as the driving component 53, rapidly generates a magnetic field upon energization, quickly applying magnetic force to the sliding component and driving it to move axially. Compared to some mechanical driving methods, electromagnet 531 has an extremely short response time, enabling the sliding component to move from the first position to the second position in a very short time. This achieves the transmission connection or separation between the lock cylinder shaft 2 and the actuating component 3, significantly improving the unlocking and locking speed of the smart lock cylinder and enhancing the user experience. Furthermore, the structure of the sliding component driven by electromagnet 531 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 particularly suitable for applications with high space requirements. Moreover, the more compact layout of electromagnet 531 and the sliding component fully utilizes the internal space of the smart lock cylinder, providing more space for the installation and functional implementation of other components, which is beneficial for the miniaturization and integrated design of the smart lock cylinder. Meanwhile, the electromagnet 531 drives the sliding parts to move through magnetic force. There is no direct friction or collision between mechanical parts during the movement, so the noise generated is extremely low. Compared with some mechanical drive methods, such as gear transmission and cam mechanism, the smart lock cylinder driven by electromagnet is quieter and less likely to cause noise interference.

[0067] A permanent magnet 621 is inserted into an electromagnet 531. When the electromagnet 531 is energized, it can quickly generate a magnetic interaction with the permanent magnet 621. Since the permanent magnet 621 itself has a stable magnetic field, it can work in conjunction with the magnetic field generated by the electromagnet 531 to quickly and powerfully drive the sliding component to move along the axial direction, achieving rapid response and precise drive, thus meeting the needs of the smart lock cylinder for fast unlocking and locking. Furthermore, the magnetic field characteristics of the permanent magnet 621 enable it to maintain a relatively stable driving force during its interaction with the electromagnet 531. Even after long-term use or under different environmental conditions, the magnetic field strength of the permanent magnet 621 changes little, ensuring the stability of the sliding component drive and reducing malfunctions and misoperations caused by unstable driving force. As a component that directly contacts the transmission component 61, the push bushing 622 prevents the permanent magnet 621 from directly contacting the transmission component 61, thereby preventing damage to the permanent magnet 621. The push bushing 622 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 622 to ensure that the surface of the push bushing 622 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. The permanent magnet 621 and the push-off bushing 622 are combined to form a sliding component. The permanent magnet 621 is responsible for magnetically driving the electromagnet 531, while the push-off bushing 622 is used to push against the transmission component 61. This structural layout makes the sliding component 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 621 and the push-off bushing 622 are easy to manufacture and assemble. During the manufacturing process, the permanent magnet 621 and the push-off bushing 622 can be processed and inspected separately, improving production efficiency and quality. During maintenance and replacement, the problematic module can be handled separately, reducing maintenance costs.

[0068] Among them, the transmission component 61 is a ball bearing structure, which has low frictional resistance, small size, small space occupation, and convenient angle adjustment to be located in the second locking position 33.

[0069] like Figure 3 and Figure 5 The permanent magnet 621 is fitted with a first reset member 624, which is located between the electromagnet 531 and the push bushing 622. In the initial state, the first reset member 624 is in a naturally extended state. Regardless of whether the unlocking is electronic or mechanical, when the sliding member, i.e., the permanent magnet 621 and the push bushing 622, moves axially away from the rotating sleeve 22, the first reset member 624 is compressed like a spring. When the unlocking is completed, the first reset member 624 drives the sliding member to move axially to reset and restore the initial state.

[0070] Example 2 See Figure 8-10 This embodiment also provides an intelligent lock cylinder, which differs from the first embodiment in that the structures of the driving component 53 and the moving component 62 are different.

[0071] In this embodiment, the rotating sleeve 22 is sleeved on the outside of the actuating member 3. The inner wall of the rotating sleeve 22 is provided with multiple locking positions 222. The hole wall of the actuating member 3 is provided with a through second connecting groove 32. The driving member 53 is a hollow cup motor 532. The movable member 62 includes a rotating wheel 625. The rotating wheel 625 is rotatably disposed in the mounting cavity 31 and corresponds to the second connecting groove 32. The peripheral side wall of the rotating wheel 625 is provided with a concave portion 6251 and a convex portion 6252. The rotation of the rotating wheel 625 can push the transmission member 61 through the convex portion 6252, which is partially exposed in the second connecting groove 32 and connected to any of the first locking positions 222, so that the rotation of the lock core shaft 2 can drive the actuating member 3 to rotate synchronously through the transmission member 61.

[0072] In the initial state, the transmission component 61 is placed in the recess 6251 and separated from the first locking position 222. When electronic unlocking is successful and authentication is passed, the circuit board 52 controls the hollow cup motor 532 to drive the rotating wheel 625 to rotate, so that the protrusion 6252 of the rotating wheel 625 aligns with the transmission component 61, thereby pushing the transmission component 61 partially exposed in the second connecting groove 32 and connecting with any of the first locking positions 222, so that the rotation of the lock cylinder shaft 2 can drive the actuating component 3 to rotate synchronously through the transmission component 61. During mechanical unlocking, the shaft 21 moves axially toward the actuating component 3, and can connect with the end of the actuating component 3 to drive the actuating component 3 to rotate synchronously.

[0073] The corresponding ends of the actuating element 3 and the shaft 21 are connected by a hexagonal structure to achieve synchronous movement. It should be noted that the hexagonal structure means that the shaft 21 may not be able to smoothly engage with the corresponding end of the actuating element 3 during mechanical unlocking. In this case, a small rotation of the handle 41 can be used to achieve precise engagement between the shaft 21 and the actuating element 3 for subsequent synchronous rotation.

[0074] In this embodiment, the movable component 62 is a rotating wheel 625. By rotating the wheel 625, the protrusions 6252 and concave portions 6251 on its peripheral sidewalls allow for precise switching between two working states. Secondly, the rotating wheel 625 fully utilizes the space of the actuating component 3, making the internal structure of the smart lock cylinder more compact. This compact design facilitates the miniaturization of the smart lock cylinder, making it easy to install in door locks of different sizes, especially suitable for applications with high space requirements. Thirdly, the rotating wheel 625 integrates the protrusions 6252 and concave portions 6251 into one unit, enabling simple rotational switching between transmission and disengagement functions, reducing the use of additional components and improving component integration. This not only reduces the manufacturing cost of the smart lock cylinder but also simplifies the installation and maintenance process. Finally, the rotating wheel 625 uses the protrusion 6252 and the concave part 6251 to precisely switch between transmission and disengagement states. Its structural design and movement mode are simple and direct. During the rotation of the rotating wheel 625, 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 625 is significantly reduced. In addition, the rolling contact transmission mode between the rotating wheel 625 and the transmission component 61 has low friction, which reduces the energy loss caused by friction. When driving the rotating wheel 625 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.

[0075] The drive unit 53 uses a coreless motor 532, which overcomes the cogging effect of ordinary motors. Of course, in practical applications, it can also be used as follows... Figure 11-12 The stepper motor 533 shown can also rotate the rotating wheel 625.

[0076] like Figure 8-10 A second reset member 626 is provided between the rotating wheel 625 and the inner wall of the shaft end of the actuating member 3. In the initial state, the second reset member 626 is in a naturally extended state. When electronic unlocking is completed and authentication is successful, the hollow cup motor 532 drives the rotating wheel 625 to rotate, so that the second reset member 626 is stretched like a torsion spring. After unlocking is completed, the hollow cup motor 532 is de-energized, and the elasticity of the second reset member 626 drives the rotating wheel 625 to reset, so that the transmission member 61 is reset and separated from the first locking position 222.

[0077] 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.
