[0001] This utility model relates to the technical field of smart locks, and more specifically, to a smart lock with a dual independent unlocking structure. Background Technology

[0002] With the rapid development of the smart home industry, smart locks, with their convenient electronic unlocking methods such as fingerprints and passwords, are gradually replacing traditional mechanical locks and are widely used in residential homes, offices and other scenarios.

[0003] In existing technologies, when a smart lock cannot be electronically unlocked due to a depleted battery, it can only be temporarily charged by an external power bank before relying on electronic unlocking. This single emergency unlocking design causes great inconvenience to users, who will be unable to open the door when they do not have a power bank. It fails to meet users' needs for convenient emergency unlocking and also reduces the overall reliability of the smart lock. Utility Model Content

[0004] The purpose of this invention is to provide a smart lock with a dual independent unlocking structure, which aims to solve the problem of the single unlocking path in existing smart locks.

[0005] This utility model is implemented as follows: a smart lock with a dual independent unlocking structure includes a square shaft, a pin seat, an electronic unlocking structure, and a mechanical unlocking structure, wherein the pin seat is fixedly connected to the square shaft. The electronic unlocking structure includes a drive motor, a retractable push rod, and a first linkage block. The first linkage block is provided with a first pin shaft, and the push rod is connected to the drive motor. The mechanical unlocking structure includes a lock body and a second linkage block. The second linkage block is located at the rear of the lock body and is provided with a second pin. When an unlock signal is received, the drive motor drives the push rod to move towards the first linkage block, and the push rod pushes the first pin shaft to move forward, so that the first pin shaft is connected to the pin seat, thereby connecting the first linkage block to the square shaft; when the key is inserted into the lock body and rotated, it pushes the second linkage block to move forward, so that the second pin shaft is connected to the pin seat, thereby connecting the second linkage block to the square shaft.

[0006] Optionally, the side of the pin holder is provided with a first pin hole adapted to the first pin shaft; the first pin shaft is connected to the pin holder by being inserted into the first pin hole.

[0007] Optionally, an arc-shaped abutment is provided between the push rod and the first linkage block, and the arc-shaped abutment abuts against the end of the first linkage block; The arc-shaped abutment is provided with a through hole, and the rear end of the first pin shaft passes through the arc-shaped abutment through the through hole. The front end of the push rod is located behind the rear end of the first pin shaft. A return spring is sleeved on the outer periphery of the first pin shaft.

[0008] Optionally, the front end face of the pin holder is provided with a second pin hole adapted to the second pin shaft, and the second pin shaft is connected to the pin holder by inserting into the second pin hole.

[0009] Optionally, the front end face of the pin holder is formed with a plurality of second pin holes, and the second linkage block is provided with a plurality of second pin shafts corresponding one-to-one with the plurality of second pin holes.

[0011] Optionally, the inner handle is connected to the inner seat, and the inner seat is provided with a deadbolt assembly; the deadbolt assembly is used to restrict the rotation of the inner handle.

[0012] Optionally, the anti-locking assembly includes a laterally movable paddle, which is disposed on the inner seat. A movable shaft is connected to the side of the paddle, and a limiting hole is provided on the side of the inner handle. When the paddle is moved toward the inner handle, the movable shaft moves toward the inner handle and is embedded in the limiting hole. Under the action of the movable shaft, the rotation of the inner handle is restricted to achieve anti-locking.

[0013] Optionally, the external handle is connected to the external base, and the external base is also provided with a display panel and a motherboard. The display panel is provided with a fingerprint unlocking module and a touch unlocking module, and the motherboard is electrically connected to the fingerprint unlocking module, the touch unlocking module and the drive motor respectively.

[0014] Optionally, the rear end face of the pin holder is provided with a connecting hole, and one end of the square shaft is fixedly embedded in the connecting hole so that the pin holder and the square shaft are fixedly connected.

[0015] Compared with existing technologies, the smart lock with a dual independent unlocking structure provided by this utility model forms a dual independent unlocking path by setting up an electronic unlocking structure and a mechanical unlocking structure.

[0020] Reference Figures 1-8 The image shown is a preferred embodiment of the present invention.

[0021] The smart lock with dual independent unlocking structure provided by this utility model includes a square shaft 400, a bolt seat 300, an electronic unlocking structure and a mechanical unlocking structure, wherein the bolt seat 300 is fixedly connected to the square shaft 400. The electronic unlocking structure includes a drive motor 500, a telescopic push rod 510, and a first linkage block 530. The first linkage block 530 is provided with a first pin shaft 531, and the push rod 510 is connected to the drive motor 500. The mechanical unlocking structure includes a lock body 600 and a second linkage block 610. The second linkage block 610 is located behind the lock body 600 and has a second pin shaft 611. When an unlock signal is received, the drive motor 500 drives the push rod 510 to move towards the first linkage block 530, and the push rod 510 pushes the first pin shaft 531 forward, so that the first pin shaft 531 is connected to the pin seat 300, thereby connecting the first linkage block 530 to the square shaft 400; when the key is inserted into the lock body 600 and rotated, it pushes the second linkage block 610 forward, so that the second pin shaft 611 is connected to the pin seat 300, thereby connecting the second linkage block 611 to the square shaft 400.

[0022] The smart lock with a dual independent unlocking structure described above forms a dual independent unlocking path by setting up an electronic unlocking structure and a mechanical unlocking structure. The two do not interfere with each other. When components such as the drive motor 500 and the retractable push rod 510 in the electronic unlocking structure malfunction, mechanical unlocking can still be achieved by turning the lock body 600 with the key to push the second linkage block 610, effectively improving the reliability and emergency protection capability of the lock. Moreover, both unlocking methods are linked with the square shaft 400 through the cooperation of the pin shaft and the pin seat 300. The structure is simple and the transmission is stable, which can ensure that the unlocking action is accurate and efficient. At the same time, the convenience of electronic unlocking and the backup attribute of mechanical unlocking are combined to adapt to diverse scenarios such as power outages and electronic component failures, taking into account both ease of use and practicality, and meeting the needs of different users.

[0023] The pin holder 300 has a first pin hole 301 on its side that mates with the first pin shaft 531. The first pin shaft 531 connects to the pin holder 300 by inserting into the first pin hole 301. This precise positioning and engagement between the first pin shaft 531 and the pin holder 300 prevents transmission failure due to connection misalignment during electronic unlocking, thus improving the stability of the electronic unlocking process. Specifically, an arc-shaped abutment 520 is provided between the push rod 510 and the first linkage block 530, and the arc-shaped abutment 520 abuts against the end of the first linkage block 530; The arc-shaped abutment 520 has a through hole, through which the rear end of the first pin 531 passes. The front end of the push rod 510 is positioned behind the rear end of the first pin 531. A return spring 532 is sleeved on the outer periphery of the first pin 531. When the push rod 510 pushes the first pin 531 to move, the rear end of the pin passes through the through hole. When the first linkage block 530 rotates with the outer handle 100, the arc-shaped abutment 520 can be used to restrict the rearward movement of the first pin 531 and keep the return spring 532 in a compressed state, ensuring that the first pin 531 is always inserted in the first pin hole 301.

[0024] The front end face of the pin holder 300 is provided with a second pin hole 302 that is adapted to the second pin shaft 611. The second pin shaft 611 is connected to the pin holder 300 by inserting into the second pin hole 302. In this way, the second pin shaft 611 is connected to the pin holder 300 by inserting into the hole.

[0025] Specifically, the front end face of the pin holder 300 has multiple second pin holes 302, and the second linkage block 610 has multiple second pin shafts 611 corresponding to the multiple second pin holes 302 one by one. The design of multiple sets of second pin shafts 611 cooperating with the second pin holes 302 significantly improves the firmness of the connection between the second linkage block 610 and the pin holder 300, avoiding deformation or detachment of a single pin due to excessive force during mechanical unlocking, and enhancing transmission stability; at the same time, multiple sets of cooperation can distribute the force, reduce the wear of individual components, further improve the durability of the mechanical unlocking structure, and adapt to different strength usage requirements. The smart lock with a dual independent unlocking structure includes an outer handle 100 and an inner handle 200. The outer handle 100 is connected to both the first linkage block 530 and the second linkage block 610, while the inner handle 200 is connected to the square shaft 400. Thus, when the first linkage block 530 and the square shaft 400 are connected, and when the second linkage block 610 and the square shaft 400 are connected, rotating the outer handle 100 will rotate the square shaft 400, thereby actuating the latch on the door. Then, by directly connecting the inner handle 200 to the square shaft 400, the inner handle 200 can directly control the rotation of the square shaft 400.

[0026] Electronic unlocking principle: When the motherboard receives a valid unlocking signal (such as fingerprint or password), the drive motor 500 starts and drives the push rod 510 to move towards the first linkage block 530. The push rod 510 precisely abuts against the rear end of the first insertion pin 531 along the guide groove on the arc-shaped abutment 520, pushing the first insertion pin 531 forward. After the first insertion pin 531 passes through the through hole, it is inserted into the first insertion pin hole 301 on the side of the insertion pin seat 300, realizing the linkage between the first linkage block 530 and the square shaft 400. At this time, the user rotates the outer handle 100, and the outer handle 100 moves... The first linkage block 530, the pin seat 300, and the square shaft 400 move synchronously to drive the locking tongue to extend and retract to complete the unlocking. At this time, the rear end of the first pin shaft 531 is forcefully pressed against the arc-shaped abutment 520 under the action of the return spring 532. After unlocking, the outer handle 100 is reset, and the first linkage block 530 rotates back. When the rear end of the first pin shaft 531 is aligned with the through hole, the first pin shaft 531 is reset and inserted into the through hole under the action of the elastic force, and then passes out of the through hole, and simultaneously disengages from the first pin hole 301. The whole process is independent of the mechanical unlocking structure and does not interfere with each other.

[0027] The lock body 600 is a relatively conventional component, consisting of a lock cylinder, a shift fork, and a lock body 600 spring. The lock cylinder is used to match the key and transmit rotational power, the shift fork connects to the lock cylinder to realize the power direction transmission, and the lock body 600 spring is responsible for the component reset after unlocking.

[0028] Mechanical unlocking principle: After the user inserts the matching key into the lock cylinder of the lock body 600 and rotates it, the key drives the lock cylinder to rotate synchronously. The fork connected to the end of the lock cylinder swings with the rotation of the lock cylinder. The free end of the fork abuts against the second linkage block 610 behind it and generates a forward thrust. The second linkage block 610 moves forward smoothly, and its multiple second pin shafts 611 move forward synchronously, accurately corresponding to and inserting into the multiple second pin holes 302 on the front end face of the pin seat 300 fixedly connected to the square shaft 400, realizing the second linkage block 610's... Linkage between 10 and square shaft 400; at this time, the user rotates the outer handle 100, the outer handle 100 drives the second linkage block 610, the pin seat 300 and the square shaft 400 to move synchronously, thereby driving the bolt to extend and retract to complete the unlocking; after unlocking, the spring of the lock body 600 inside the lock body 600 releases its elastic force, causing the shift fork to swing in the opposite direction, and at the same time, the reset structure on the second linkage block 610 drives it to reset, and the second pin shaft 611 disengages from the second pin hole 302. The whole process is independent of the electronic unlocking structure and does not interfere with each other.

[0029] The reset structure on the second linkage block 610 can be an intermediate spring between the pin seat 300 and the second linkage block 610.

[0030] Both the outer handle 100 and the inner handle 200 are equipped with a return torsion spring.

[0031] In a preferred embodiment, the inner handle 200 is connected to the inner seat 201, and the inner seat 201 is provided with a deadbolt assembly; the deadbolt assembly is used to restrict the rotation of the inner handle 200. Thus, the inner handle 200 is connected to the inner seat 201, and the inner seat 201 is provided with a deadbolt assembly to restrict the rotation of the inner handle 200. Integrating the deadbolt assembly into the inner seat 201 results in a compact structure that does not occupy too much internal space of the lock body 600, facilitating overall assembly. The deadbolt function effectively restricts the rotation of the inner handle 200, enhancing home security and preventing outsiders from prying the handle open the door from inside, creating a safe living environment for users.

[0032] In this embodiment, the deadbolt assembly includes a laterally movable lever 700, which is disposed on the inner seat 201. A movable shaft 710 is connected to the side of the lever 700, and a limiting hole 202 is provided on the side of the inner handle 200. When the lever 700 is moved toward the inner handle 200, the movable shaft 710 moves toward the inner handle 200 and engages in the limiting hole 202. Under the action of the movable shaft 710, the rotation of the inner handle 200 is restricted, thus achieving deadbolt locking. In this way, deadbolt locking is achieved by moving the lever 700 to drive the movable shaft 710 into the limiting hole 202. This structural design is simple and easy to operate. Unlocking only requires moving the lever 700 in the opposite direction, making it suitable for frequent deadbolt and unlocking scenarios.

[0033] Specifically, the outer handle 100 is connected to the outer base 101, which also houses a display panel and a mainboard. The display panel includes a fingerprint unlocking module 120 and a touch unlocking module 110. The mainboard is electrically connected to the fingerprint unlocking module 120, the touch unlocking module 110, and the drive motor 500. This integrated layout of electronic unlocking components improves the neatness of the internal structure and facilitates future maintenance. The dual fingerprint and touch unlocking modules enrich the electronic unlocking methods, adapting to different user habits. The centralized control of the mainboard ensures efficient signal transmission and rapid response, enhancing the convenience and sensitivity of electronic unlocking.

[0034] The pin holder 300 has a connecting hole 303 on its rear end face. One end of the square shaft 400 is fixedly embedded in the connecting hole 303, so that the pin holder 300 and the square shaft 400 are fixedly connected. The connection is strong and the embedded fit allows the pin holder 300 and the square shaft 400 to form a tight integrated structure, effectively avoiding relative displacement or loosening due to force during the unlocking transmission process. This ensures that power can be accurately transmitted to the square shaft 400 through the pin holder 300 under both electronic and mechanical unlocking methods, ensuring the stability and reliability of the unlocking action.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
