Detailed Implementation

[0029] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0030] Example

[0031] Please refer to Figures 1-6 This application provides an intelligent locking device, comprising: a lock body including a lock shell 1, a mechanical lock cylinder 3, and a positioning bolt 24 that cooperate with each other; a first gear 11 coaxially connected to the output end of the mechanical lock cylinder 3; a first synchronous gear 12 sleeved on the first gear 11; a transmission assembly including a transmission shaft 14, a second gear 13, a third gear 15, and an output gear set; the transmission shaft 14 being spaced apart from the side of the first gear 11 and coaxially arranged with the first gear 11; the second gear 13 and the third gear 15 being respectively disposed at both ends of the transmission shaft 14, with the second gear 13 and the first gear 11 facing each other; the output gear set being drively connected to the transmission shaft 14 and the positioning bolt 24 for driving the positioning bolt 24 to lock or unlock; and an electric drive assembly including a first drive motor 5, a fourth gear 16, and a second synchronous gear 17. The fourth gear 16 is spaced apart on the side of the third gear 15 and coaxially arranged with the third gear 15. The fourth gear 16 is fitted with a slidable second synchronous gear 17. The first drive motor 5 is used to drive the fourth gear 16 to rotate. The first synchronous gear 12 and the second synchronous gear 17 are each provided with a toggle module 10 for adjusting the sliding of the first synchronous gear 12 or the second synchronous gear 17. The control components include a control unit, a communication module, an identification module and a detection module that cooperate with each other. When the detection module detects that the key is inserted into the mechanical lock cylinder 3, the control unit uses the toggle module 10 to connect the first synchronous gear 12 with the first gear 11 and the second gear 13. When the detection module detects that the key is not inserted into the mechanical lock cylinder 3, the control unit uses the toggle module 10 to disengage the first synchronous gear 12 from the second gear 13.

[0032] The intelligent locking system of this application offers diverse and convenient usage. When traditional key unlocking is required, the key is inserted into the mechanical lock cylinder 3. The detection module quickly detects the key insertion, and the control unit, via the toggle module 10, precisely connects the first synchronous gear 12 to the first gear 11 and the second gear 13. Twisting the mechanical lock cylinder 3 causes the first gear 11 to drive the second gear 13, which in turn drives the output gear set via the transmission shaft 14, thus unlocking the positioning bolt 24. Reversing this process locks the lock. In intelligent unlocking scenarios, the identification module performs identity verification. Upon successful verification, the control unit connects the second synchronous gear 17 to the third gear 15 and the fourth gear 16, causing the first drive motor 5 to rotate and complete the unlocking action. This solution offers significant advantages, organically integrating traditional mechanical unlocking and intelligent unlocking methods. On one hand, it meets the user's needs in various scenarios, easily handling both emergency mechanical unlocking when there is no power and convenient daily intelligent unlocking. On the other hand, its carefully designed gear transmission and control components ensure the reliability and stability of the lock's operation. In terms of security, multiple unlocking verification methods enhance the protection level; in terms of convenience, intelligent unlocking reduces operating steps. In contrast, traditional smart door locks have complex transmission structures, often resulting in uneven operation and impacting the user experience. The smart door lock of this application, however, features an optimized transmission design, making it easy to operate and significantly improving practicality.

[0033] Specifically, a power module is also provided inside the lock housing 1 for power supply.

[0034] In a preferred embodiment, the output gear set includes a first output gear 8 and a second output gear 9 that mesh with each other. The first output gear 8 is sleeved on the transmission shaft 14, and the positioning lock tongue 24 is provided with a spur tooth structure adapted to the second output gear 9.

[0035] In the above embodiment, the meshing of the first output gear 8 and the second output gear 9 effectively transmits power, achieving a reasonable distribution and conversion of force. The first output gear 8 is sleeved on the transmission shaft 14, efficiently receiving the power transmitted by the transmission shaft 14 and stably transmitting it to the meshing second output gear 9. The positioning latch 24 is equipped with a spur gear structure adapted to the second output gear 9, enabling the second output gear 9 to precisely and directly drive the positioning latch 24 to lock or unlock. This tight fit effectively ensures the accuracy and stability of the positioning latch 24's movement, allowing the lock to operate more reliably and smoothly during use, and ensuring the core functions of the lock are well realized.

[0036] In a preferred embodiment, the second output gear 9 is coaxially connected to the ratchet and pawl structure 6, and the pawl component of the ratchet and pawl structure 6 is connected to the second drive motor 7.

[0037] In the above embodiment, after the locking operation is completed, if the detection module does not detect the key, the pawl will immediately lock the ratchet to prevent the positioning bolt 24 from moving in the unlocking direction. When the detection module detects a key insertion, or when the recognition module responds, the second drive motor 7 will drive the pawl to unlock the ratchet and pawl structure 6. This design enhances the controllability of the lock operation and improves the reliability and security of the entire system.

[0038] As a preferred embodiment, a rotary encoder is also included for monitoring the rotation of the aforementioned mechanical lock cylinder 3.

[0039] In the above embodiments, the rotary encoder identifies the forward or reverse rotation of the mechanical lock cylinder 3, thereby controlling the operation of the pawl mechanism by the second drive motor 7. When the mechanical lock cylinder 3 rotates forward to perform a locking operation, the ratchet and pawl structure 6 operates normally, maintaining the locked state of the lock. When the mechanical lock cylinder 3 rotates in reverse to perform an unlocking operation, the second drive motor 7 receives a signal from the rotary encoder and drives the pawl mechanism to no longer limit the ratchet and pawl structure 6, allowing the unlocking action to be completed smoothly. Through this precise corresponding control, misoperation and unexpected situations are effectively reduced, greatly improving the reliability of the smart lock used in this application.

[0040] In a preferred embodiment, the transmission shaft 14 is fitted with a fifth gear 18, the fifth gear 18 meshes with a sixth gear 19, the sixth gear 19 is coaxially fitted with a seventh gear 20, the seventh gear 20 is fitted with a slidable third synchronous gear 22, the side of the seventh gear 20 is coaxially and spaced apart with an eighth gear 21, and the eighth gear 21 is fitted with a mechanical lock core 4.

[0041] Among them, the mechanical lock cylinder 3 and the mechanical lock cylinder 4 are respectively disposed on both sides of the outer side of the lock housing 1, and the third synchronous gear 22 is connected to another actuating module 10.

[0042] In the above embodiment, mechanical lock cylinder one and mechanical lock cylinder two 4 are located on opposite sides of the outer side of the lock housing 1, that is, outside and inside the door. This means that the user can operate the lock conveniently whether indoors or outdoors. From the outside, the user can unlock the door normally using mechanical lock cylinder one 3, which conforms to daily usage habits. Indoors, the presence of mechanical lock cylinder two 4 provides users with additional convenience. In case of an emergency, such as a sudden power outage indoors and the smart system being unusable, the user does not need to fumble in the dark to find other emergency tools; they can quickly open the door directly using mechanical lock cylinder two 4. The fifth gear 18 and the sixth gear 19 mounted on the transmission shaft 14 mesh, thereby driving the coaxially mounted seventh gear 20 to rotate. The slidable third synchronous gear 22 mounted on the seventh gear 20 is controlled by another actuating module 10, which can flexibly connect or disconnect the transmission with different gears. When the mechanical lock cylinder 24 needs to function, the third synchronous gear 22 can connect with the eighth gear 21, enabling the mechanical lock cylinder 24 to rotate through a series of gear transmissions, achieving the same control and positioning function of the bolt 24 as the mechanical lock cylinder 3. This ensures consistency and continuity of indoor and outdoor operation, greatly improving the practicality and convenience of the lock. The actuation module 10 can be a hydraulic structure.

[0043] In a preferred embodiment, the detection module includes an active triggering module and a passive triggering module that cooperate with each other, and are respectively disposed in the key and the key slot.

[0044] In the above embodiment, when the key is inserted into the key slot, the active trigger module and the passive trigger module sense each other, accurately detecting the key insertion action with a sensitive response. Compared to other detection methods, this design is highly targeted and effectively avoids false alarms. For example, it will not be misjudged due to interference from surrounding metal objects. Moreover, this setup is simple and direct, with low installation and maintenance costs. The corresponding trigger modules for the key and key slot eliminate the need for complex wiring or additional structures, reliably achieving the key insertion detection function, ensuring the lock responds promptly to key operations, and improving overall performance.

[0045] As a preferred embodiment, it also includes a second positioning bolt 23 disposed on the lock housing 1. The second positioning bolt 23 includes a first positioning body 231 and a second positioning body 232 that are telescopically engaged. A spring 233 is disposed between the first positioning body 231 and the second positioning body. The first positioning body 231 is fixedly disposed on the lock housing 1.

[0046] In the above embodiment, the second positioning bolt 23 is used for the initial locking of the lock. When the door is closed, it can quickly take effect without complicated operation, providing an immediate level of security. It is particularly suitable for simple locking scenarios when someone is home, such as when family members are resting at home during the day. Using the second positioning bolt 23 can easily achieve basic protection, which is both convenient and practical. The first positioning bolt 24 is activated when further security is required, for further locking of the lock. This layered locking design not only meets the security needs in different scenarios but also improves the ease of use.

[0047] In a preferred embodiment, a handle 2 rotatably disposed on the lock housing 1 is also included, the handle 2 being used to drive the extension and retraction of the second positioning body 232 on the first positioning body 231.

[0048] There are two handles 2, which are respectively located on both sides of the outer side of the lock housing 1.

[0049] In the above embodiment, two handles 2 are respectively located on both sides of the outer side of the lock housing 1, making operation convenient whether inside or outside the door. By rotating the handle 2, the second positioning body 232 can be extended or retracted on the first positioning body 231, realizing the locking and unlocking of the second positioning bolt 23. The operation is intuitive and simple. This greatly improves the convenience of daily use for users, such as easily controlling the state of the second positioning bolt 23 when entering or leaving the house. Moreover, in emergency situations, whether people are inside or outside the house, they can quickly operate the handle 2 to quickly open or close the second positioning bolt 23, ensuring safety. This design, combined with the handle 2, cleverly integrates the daily opening and closing actions with the function of the second positioning bolt 23, making it both practical and efficient.

[0050] In a preferred embodiment, the identification module includes a biometric module and a non-biometric module. The biometric module includes a fingerprint recognition module and a facial recognition module, and the non-biometric module includes a password recognition module and a card recognition module.

[0051] The control unit includes a microprocessor and a storage unit, and the communication module includes a Bluetooth module and a WiFi module.

[0052] In the above embodiments, the identification module encompasses two main types: biometric and non-biometric. Biometric modules, including fingerprint and facial recognition, leverage unique human physiological characteristics to provide accurate and convenient unlocking methods with extremely high security. Non-biometric modules, such as password and card recognition, cater to different user preferences and usage scenarios; for example, users can quickly unlock by swiping a card when in a hurry, or enter a password if they forget their card. The control unit's microprocessor ensures efficient data processing and instruction execution, while the storage unit stably stores user information and unlocking records. The communication module includes Bluetooth and WiFi modules, allowing users to flexibly choose connection methods. Bluetooth facilitates short-range mobile phone control, while WiFi supports remote control, greatly enhancing the flexibility, convenience, and security of the lock, comprehensively meeting diverse user needs.

[0053] As a preferred embodiment, the inner wall of the lock housing 1 is provided with sound insulation cotton.

[0054] In the above embodiment, sound-insulating cotton is provided on the inner wall of the lock housing 1, which can effectively reduce the noise generated by the lock during use. Whether it is the extension and retraction of the bolt when opening or closing, or the sound of mechanical parts operating, the sound-insulating cotton can absorb and block it, reducing the interference of noise on the indoor environment. Especially at quiet nights or in noise-sensitive environments, the noise of the lock opening and closing will not disturb the rest or work of others.

[0055] Furthermore, unless otherwise explicitly specified or limited, the terms "installation" and "connection" in this application embodiment should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The terms "upper," "lower," "left," "right," "inner," "outer," and "side," etc., are merely for reference to the direction in the accompanying drawings or the usual placement of the product during use. They are only for clearly describing this application and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limitations on this application. The terms "first," "second," etc., are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance; "multiple" refers to at least two.
