Description

Technical Field

[0001] This utility model relates to the field of door locks, specifically to a novel electronic lock body. Background Technology

[0002] Electronic locks are improved versions of traditional mechanical locks, offering greater intelligence and convenience in terms of user security, identification, and management. Types of electronic locks include fingerprint locks, electronic combination locks, proximity locks, and smart locks. While smart locks are becoming increasingly diverse with various unlocking methods, existing electronic locks generally suffer from significant noise when opening and closing, easily disrupting daily life.

[0003] To address the issue of smart locks failing to open due to electronic unlocking malfunctions, smart locks typically retain a mechanical key unlocking method as an emergency solution. The mechanical key requires rotation within the electronic lock's internal structure to achieve mechanical opening and closing. Therefore, the mechanical unlocking method of electronic locks warrants further in-depth research and exploration. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] This utility model provides the following technical solution:

[0031] As attached Figure 1-9 As shown, this utility model discloses a novel electronic lock body. The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The present invention will now be further described with reference to the accompanying drawings.

[0033] This utility model provides the following technical solution:

[0034] As attached Figure 1-9As shown, this utility model discloses a novel electronic lock body, including a lock box 1 and a latch assembly 2 disposed on one side of the lock box 1. The lock box 1 is provided with a bolt 3 and a bolt transmission assembly 4 that drives the bolt 3 to move inside and outside the lock box 1 when the door is open or closed. The key feature is that a magnetic element 5 is disposed inside the bolt 3, and a magnetic attracting element 6 is disposed inside the latch assembly 2. The magnetic element 5 and the magnetic attracting element 6 are attracted to each other by opposite poles. When the door is closed, the magnetic attracting element 6 drives the magnetic element 5 inside the bolt 3 to move through magnetic force, thereby connecting the bolt 3 and the latch assembly 2. In this embodiment, the magnetic attracting element 6 and the magnetic element 5 achieve a noiseless connection between the lock box 1 and the latch assembly 2 through magnetic attraction, while providing a stable locking force. The cooperative design of the magnetic attracting element 6 and the magnetic element 5 not only effectively reduces the noise generated by the lock body, but also ensures the stability of the lock when closed through magnetic force. This magnetic interaction not only simplifies the lock body structure and reduces wear and malfunction points that may exist in traditional mechanical locks, but also significantly improves the smoothness and quietness of the unlocking and locking process. In this embodiment, the magnetic attractor 6 is a strong magnet, and the magnetic component 5 is a steel plate. The function of the latch transmission assembly 4 is to drive the latch 3 to move. Specifically, when the latch 3 is subjected to external force, the latch transmission assembly 4 transmits the force through elastic deformation, so that the latch 3 can smoothly and quickly extend into the lock box 1. In specific implementation, the various parts of the elastic transmission assembly work closely together to achieve smooth movement and precise positioning of the latch 3. The latch 3 is a bidirectional latch 3, and inclined tongue surfaces 7 are provided on both sides of the latch 3. When closing and opening the door, the inclined tongue surfaces 7 first contact the latch assembly 2 and convert the squeezing force between the inclined tongue surfaces 7 and one side of the latch assembly 2 into a pushing force on the latch 3, pushing the latch 3 into the lock box 1 to achieve smooth closing.

[0035] Furthermore, a magnetic groove 8 is formed on the side of the latch 3 near the latch transmission assembly 4. The magnetic element 5 is disposed within the magnetic groove 8, and one end of the latch transmission assembly 4 extends into the magnetic groove 8 and abuts against the magnetic element 5 within the magnetic groove 8. In this embodiment, the magnetic groove 8 provides a stable installation position for the magnetic element 5, ensuring that the magnetic element 5 will not shift or fall off during the movement of the latch 3, thereby ensuring the stability and reliability of the magnetic force between the magnetic attractor 6 and the magnetic element 5. Simultaneously, the design of the magnetic groove 8 facilitates the installation and replacement of the magnetic element 5, improving the maintainability and expandability of the lock body. In practical applications, the size and shape of the magnetic groove 8 are precisely designed according to the specifications of the magnetic element 5 and the overall structure of the latch 3 to ensure that the magnetic element 5 can fit tightly against the groove wall of the magnetic groove 8 under the abutment of the latch transmission assembly 4, maximizing the magnetic force reception effect of the magnetic element 5 and strengthening the attraction between the magnetic element 5 and the magnetic attractor 6.

[0036] Furthermore, the latch assembly 2 includes a latch body 9 and a rear cover 10. A latch groove 11 is formed on the end face of the latch body 9 near the latch tongue 3. The latch tongue 3 extends into the latch groove 11 and connects to the latch assembly 2. A magnetic groove 12 is provided on the side of the latch body 9 away from the latch tongue 3. The magnetic attractor 6 is disposed within the magnetic groove 12. The rear cover 10 is disposed at the opening of the magnetic groove 12 to seal it. In this embodiment, the latch body 9 provides connection space for the latch tongue 3 to extend into, ensuring a stable connection between the latch tongue 3 and the latch assembly 2. The design of the latch groove 11 precisely corresponds to the connection position between the latch tongue 3 and the latch assembly 2, allowing the latch tongue 3 to smoothly extend into the latch groove 11 and achieve a noiseless and stable connection with the latch assembly 2. Meanwhile, the magnetic groove 12 on the latch body 9 provides installation space for the magnetic component 6, allowing it to be stably positioned within the magnetic groove 12 and forming a stable attraction between opposite poles with the magnetic component 5 in the latch tongue 3. This enhances the locking effect and quietness of the lock. The rear cover 10 seals the magnetic groove 12, effectively preventing dust, moisture, and other external factors from entering and damaging the magnetic component 6, thus further extending the lock's lifespan.

[0037] Furthermore, at least one side wall of the magnetic latch groove 12 is parallel to one side wall of the bolt groove 11, and the magnetic component 5 is attached to the wall of the bolt magnetic groove 8. Both the bolt groove 11 and at least one side wall of the magnetic latch groove 12 are sloped. In this embodiment, the parallel and sloped design of the walls of the magnetic latch groove 12 and the bolt groove 11 optimizes the magnetic force transmission path between the magnetic component 5 and the magnetic attracting component 6, ensuring that they form a maximum and stable magnetic attraction surface when in contact. This design not only enhances the stability of the lock in the closed state but also effectively reduces noise or vibration that may be caused by uneven magnetic force distribution. The sloped shape further guides the movement trajectory of the bolt 3 as it extends into the bolt groove 11, making it smoother and more precise, thus improving the user's door opening and closing experience. Simultaneously, this design also considers the feasibility and cost-effectiveness of the manufacturing process, ensuring that the lock body maintains high performance while remaining competitive in the market.

[0038] Furthermore, the latch transmission assembly 4 includes a latch connector 13, a connecting rod 14, and a limiting block 15. The limiting block 15 is fixed relative to the inner wall of the lock box 1. One end of the connecting rod 14 passes through the limiting block 15 and connects to the latch connector 13. Connecting springs 16 and limiting springs 17 are respectively provided on the outer sides of the connecting rod 14 located on both sides of the limiting block 15. The two ends of the connecting spring 16 abut against the latch connector 13 and the limiting block 15, respectively. One end of the limiting spring 17 is connected to a limiting plate, and the other end is connected to the end of the connecting rod 14 away from the latch 3. One end of the latch connector 13 is connected to the latch 3. In this embodiment, the function of the latch transmission assembly 4 is to achieve smooth and precise movement of the latch 3 in the open or closed state through the coordinated work of the latch connector 13, the connecting rod 14, and the limiting block 15. The latch connector 13 serves as the connection hub between the latch 3 and the connecting rod 14, ensuring the stability and reliability of force transmission. The connecting rod 14 passes through the limiting block 15, not only connecting the latch connector 13 and the latch 3, but also precisely controlling the movement range of the latch 3 through the connecting spring 16 and the limiting spring 17 located on both sides of the limiting block 15. The two ends of the connecting spring 16 abut against the latch connector 13 and the limiting block 15 respectively, providing a restoring force for the latch 3 and ensuring that the latch 3 automatically springs back to its initial position after the door is opened. The limiting spring 17 connects to the limiting plate at one end and to the end of the connecting rod 14 away from the latch 3 at the other end, further limiting the movement range of the connecting rod 14, thereby ensuring the accuracy and stability of the latch 3's movement. This design not only simplifies the structure of the latch transmission assembly 4 but also improves its reliability and durability. In this embodiment, a return boss is provided at the end of the connecting rod 13 away from the locking tongue 3. The return boss is coaxially arranged with the connecting rod 13. The diameter of the return boss is slightly larger than the cross-sectional diameter of the connecting rod 13. One end of the return spring 16 is connected to the limiting plate 14, and the other end of the return spring 16 is connected to the return boss.

[0039] Furthermore, a clutch device 18 is also provided inside the lock box 1. The clutch device 18 includes a fixing frame 19, a clutch assembly 20, and a motor 21. The fixing frame 19 is installed on the inner wall of the lock box 1 and fixedly connected to the lock box 1. The motor 21 is located inside the fixing frame 19, with one end extending out and connected to the clutch assembly 20. The motor 21 drives the clutch assembly 20 to move. In this embodiment, the function of the clutch device 18 is to achieve precise movement of the clutch assembly 20 through the drive of the motor 21, thereby controlling the working state of the lock tongue transmission assembly 4 and realizing the automatic unlocking and locking functions of the lock. The fixing frame 19, as the supporting structure of the clutch device 18, ensures the stable installation of the motor 21 and the clutch assembly 20, providing a reliable working environment for the entire clutch device 18. The high precision and stability of the motor 21, as the power source, directly affect the moving accuracy of the clutch assembly 20 and the overall performance of the lock.

[0040] Furthermore, the clutch assembly 20 includes a movable frame 22, a movable plate 23, and a support plate 24. The movable frame 22 is disposed within the fixed frame 19, and a transmission groove 25 is formed on the movable frame 22. One end of the motor 21 extends into the transmission groove 25 and is connected to the movable frame 22. The support plate 24 is disposed at the end of the movable plate 23 away from the fixed frame 19. The movable frame 22 and the movable plate 23 are connected by the motor 21, which drives the movable frame 22 and the movable plate 23 to move toward the side closer to the latch transmission assembly 4. The support plate cooperates with the movable plate 23 to limit the movement of the latch transmission assembly 4. Specifically, in this embodiment, the motor 21 has an output end 26. A movable spring 27 is also provided on the outer side of the output end 26 within the transmission groove 25. The two ends of the movable spring 27 abut against the opposite side walls of the transmission groove 25. A limit rod 28 is provided on the output end 26 of the motor. The limit rod 28 extends into the movable spring 27 and connects to it. The limit rod 28 on the output end 26 rotates along the spiral groove on the movable spring 27, compressing the movable spring 27 during rotation. As the movable spring 27 is compressed, its stored elastic potential energy gradually increases. During the locking process, when the motor 21 stops rotating, the movable spring 27 releases its elastic potential energy, pushing the movable frame 22 towards the latch 3, thereby causing the movable plate 23 to move towards the latch transmission assembly 4. The movable plate 23 moves to the side of the support plate 24 near the latch transmission assembly 4, limiting one end of the connecting rod 14, preventing the latch 3 and the latch transmission assembly 4 from moving into the lock box 1. Conversely, during the unlocking process, the motor 21 reverses direction, the limiting rod 28 rotates in the opposite direction, and the moving spring 27 is compressed again. Simultaneously, the moving frame 22 moves away from the bolt 3, and the moving plate 23 is also driven to move away from the bolt 3. In this embodiment, the clutch assembly 20 functions to flexibly control the movement state of the bolt transmission assembly 4 through the coordinated action of the moving frame 22, the moving plate 23, and the support plate 24, as well as the precise control of the motor 21 and the moving spring 27. This design not only ensures the lock maintains a stable locked state when locked, preventing the bolt 3 from accidentally retracting, thus ensuring door safety; but also quickly releases the limiting force on the bolt transmission assembly 4 during unlocking, allowing the bolt 3 to smoothly retract into the lock box 1, achieving rapid unlocking. Furthermore, the moving spring 27 also serves as a buffer and energy storage mechanism. After the motor 21 rotates, the stored elastic potential energy can be used to push the moving frame 22 and the moving plate 23, further improving the lock's response speed and stability. In this embodiment, the support plate 24 is provided with a support hole 29. In the unlocked state, the end of the lock tongue transmission assembly 4 away from the lock tongue 3 extends into the support hole 29, and the lock tongue transmission assembly 4 can move in both directions of the support hole 29.When closed, the movable plate 23 moves to one side of the support hole 29 and abuts against the latch transmission assembly 4 moving towards the support plate. In this embodiment, the design of the support hole 29 provides a clear range of movement for the latch transmission assembly 4, ensuring the stability and accuracy of the latch transmission assembly 4 during movement. In the unlocked state, the end of the latch transmission assembly 4 away from the latch 3 can freely extend into the support hole 29 and can move to a limited extent in both directions of the support hole 29. This design allows the latch transmission assembly 4 to maintain a smooth movement trajectory when subjected to external force. In the closed state, the movable plate 23 moves to one side of the support hole 29 and abuts against the latch transmission assembly 4 moving towards the support plate, effectively preventing the latch 3 from moving towards the lock box 1 during closing, thereby ensuring the safe locking of the door. The movable frame 22 serves as a key transmission component in the clutch assembly 20. The movable frame 22 is tightly connected to the protruding end of the motor 21 through the transmission groove 25, converting the rotational motion of the motor 21 into linear motion. The transmission groove 25 not only provides a stable connection space for the output end 26 of the motor 21, but also, through the cooperation of the limiting rod 28 and the moving spring 27, achieves precise control over the movement of the moving frame 22. Driven by the motor 21, the moving frame 22 slides smoothly along the interior of the fixed frame 19, driving the connected moving plate 23 to move synchronously, thereby completing the limiting or releasing operation of the lock tongue transmission assembly 4. This structural design ensures that the clutch assembly 20 can accurately respond to the command of the motor 21, realizing reliable switching between the open and closed states of the lock.

[0041] Furthermore, a rotating member 30 is provided on one side of the clutch assembly 20. The rotating member 30 is rotatably disposed within the lock housing 1. A rotating end 31 protrudes from the rotating member 30. A moving groove 32 is provided on the moving plate 23 corresponding to the position of the rotating end 31. The rotating end 31 extends into the moving groove 32, driving the moving plate 23 to move away from the latch transmission assembly 4. In this embodiment, the function of the rotating member 30 is to achieve the directional movement of the moving plate 23 by engaging its rotating end 31 with the moving groove 32 on the moving plate 23. Specifically, when the rotating member 30 rotates, its rotating end 31 extends into the moving groove 32 and drives the moving plate 23 to move along a preset trajectory away from the latch transmission assembly 4. This design cleverly utilizes the linkage of the mechanical structure, enabling the rotational motion of the rotating member 30 to be efficiently converted into the linear motion of the moving plate 23, thereby achieving the adjustment of the state of the latch transmission assembly 4. In this embodiment, the rotating component 30 is further provided with a locking end 33, and the moving plate 23 is provided with a locking groove 34 corresponding to the locking segment. During normal opening and closing, the rotating end 31 of the rotating component 30 is positioned outside the moving groove 32, and the locking end 33 extends into the locking groove 34 and connects with the groove wall of the locking groove 34 near the bolt 3. The locking groove 34 and the locking segment are configured to ensure that the moving groove 32 on the moving plate 23 is within a range that can cooperate with the rotating end 31. When the door lock cannot be opened normally, rotating the rotating component 30 causes the locking end 33 to move out of the locking groove 34, while the rotating end 31 rotates towards the moving groove 32, driving the moving plate 23 to move away from the bolt 3. This allows the bolt transmission assembly 4 to move back into the lock box 1. The door lock then opens normally.

[0042] Furthermore, a torsion spring 35 is provided on one side of the rotating component 30. One side of the torsion spring 35 is connected to the lock box 1, and the other side of the torsion spring 35 is in contact with the rotating component 30. The torsion spring 35 limits the rotation angle of the rotating component 30. In this embodiment, the main function of the torsion spring 35 is to provide a stable return force for the rotating component 30, ensuring that the rotating component 30 has rotated to the corresponding rotation angle after rotation, avoiding the problem of the rotating component 30 stopping after rotating halfway or at other different angles. This design not only simplifies the operation process but also improves the reliability of the lock. Specifically, one end of the torsion spring 35 is in contact with the lock box 1, and the other end of the torsion spring 35 is perpendicularly in contact with the rotating component 30. When the rotating component 30 rotates under the action of external force, the end of the torsion spring 35 in contact with the rotating component 30 is compressed, storing elastic potential energy. Once the external force disappears and the rotating component 30 is angularly offset, the torsion spring 35 releases its stored elastic potential energy, pushing the rotating component 30 to rotate to the angle it engages with. This automatic return mechanism effectively prevents the rotating component 30 from being in a half-open or half-closed state, ensuring the lock's open and closed states. Simultaneously, the torsion spring 35 precisely limits the rotation angle of the rotating component 30, avoiding the risk of damage to the lock's internal structure due to excessive rotation.

[0043] In this embodiment, the lock box 1 also contains a battery 36 and a main control board 37. The battery 36 is electrically connected to the main control board 37, and the main control board 37 is connected to the clutch device 18. The battery 36 and the main control board 37 are common structures in the prior art and will not be described in detail in this embodiment.

[0044] The working principle of this embodiment is as follows: When the door is closed, the lock box 1 drives the latch transmission assembly 4 and the latch 3 to move towards the latch assembly 2. The inclined tongue surface 7 of the latch 3 contacts one side of the latch assembly 2. The pushing force causes the latch 3 to be squeezed by the latch assembly 2. The inclined tongue surface 7 of the latch 3 converts the squeezing force into a pushing force for the latch 3 to move into the lock box 1. The connecting rod 14 in the latch transmission assembly 4 moves, the connecting spring 16 is compressed, and the latch 3 is pressed into the lock box 1 and continues to move. When the latch 3 moves to the latch groove 11 position of the latch assembly 2, the latch 3 is no longer squeezed. Due to the rebound force of the limit spring 17, the latch 3 extends out of the lock box 1 and into the latch groove 11 until the limit spring 17 and the return spring return to their normal state. At this time, the magnetic element 5 in the magnetic groove 8 of the latch is attracted by the magnetic force of the magnetic attractor 6. The magnetic force is greater than the elastic force of the return spring, causing the latch 3 to continue to extend into the latch groove 11 until it reaches the designated position. At this time, the main control board 37 receives the signal and issues a control command to the motor 21 according to the preset program. The motor 21 drives the moving frame 22 and the moving plate 23 to move. The moving plate 23 moves to the side of the support plate near the latch transmission assembly 4, and abuts against the latch transmission assembly 4 moving towards the support plate. This prevents the latch 3 from extending back in the latch groove 11 of the latch assembly 2 due to the action of the limiting spring 17 and the return spring, thus realizing the locking function between the latch 3 and the latch assembly 2.

[0045] When the door lock needs to be opened, the user inputs an open signal. The main control board 37 receives the signal and issues a corresponding control command, causing the motor 21 to reverse and drive the moving frame 22 to move in the opposite direction. The moving frame 22 drives the moving plate 23 to move away from the latch 3. At this time, the latch 3 is in a freely retractable state. Simply push the door open, and the inclined surface of the latch 3 near the magnetic 6 contacts the corresponding side of the latch groove 11. The inclined surface of the latch groove 11 compresses the inclined tongue surface 7 of the latch 3. After being squeezed, the latch 3 retracts into the lock box 1 until the lock box 1 moves away from the strike plate, at which point the latch 3 pops out, completing the door opening.

[0046] In the event of a power or communication failure, or other reasons preventing the lock from being opened normally, the user can manually open it by rotating the rotating component 30. Rotating the rotating component 30 causes the rotating end 31 to rotate, moving it into the moving groove 32. This causes the moving plate 23 to move away from the bolt 3, allowing the bolt transmission assembly 4 to move freely and open the lock. This design provides users with a simple and effective emergency opening method in special circumstances, further improving the security and reliability of the lock.

[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
