Technical Field

[0001] This utility model relates to the field of smart lock technology, specifically to a locking mechanism for a smart lock and a smart lock. Background Technology

[0002] Locks are an important component of access control systems. With the continuous development of large-scale integrated circuit technology, sensor technology, and Internet of Things technology, more and more smart locks have evolved from traditional mechanical locks. These smart locks have unlocking methods such as fingerprint, password, and facial recognition, which diversifies the unlocking methods and solves the problem of not being able to open the door if you forget your key. Smart locks also have many advantages, such as security, intelligence, diversified unlocking methods, and high-end design. Therefore, more and more people are choosing smart locks to replace traditional mechanical locks.

[0003] Some smart locks use a relatively simple electric bolt structure for their locking mechanism. After long-term use, the bolt is prone to jamming or loosening due to wear or external impact, resulting in unstable locking and affecting the security of the smart lock. The unlocking and locking process of some smart locks is not smooth enough, requiring greater force or complicated steps to operate, which not only reduces the user experience but may also affect the user's escape efficiency in an emergency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Example:

[0029] Please see Figures 1-5This utility model provides a technical solution: a locking mechanism for a smart lock, including a first fixed frame 1, a second fixed frame 2, a rotating ring block 3, and a limiting component. The first fixed frame 1 and the second fixed frame 2 are symmetrically distributed about the rotating ring block 3. The limiting component is located between the first fixed frame 1 and the second fixed frame 2 and is in contact with the rotating ring block 3. The limiting component includes a limiting post 4, a plug-in block 16, and a plug-in groove 17. The plug-in block 16 enters the plug-in groove 17 to lock the rotating ring block 3, thereby achieving the locking function of the smart lock. The limiting post 4 restricts the movement range of the plug-in block 16.

[0030] In this embodiment, a telescopic cylinder 6 is fixedly installed in the first fixed frame 1, and a sliding plate 7 is fixedly installed at the output shaft end of the telescopic cylinder 6. A first rack post 8 and a second rack post 9 are fixedly installed on one side of the sliding plate 7 respectively. When the telescopic cylinder 6 is working, it can drive the sliding plate 7 to move in the first fixed frame 1, and at the same time, the sliding plate 7 will also move in the second rack post 9 in the second fixed frame 2.

[0031] In this embodiment, a first connecting post 5, a rotating gear 10, and a second connecting post 11 are movably installed in the second fixed frame 2. The top ends of the first connecting post 5 and the second connecting post 11 are fixedly connected to the plug block 16. The first connecting post 5 and the second connecting post 11 can slide in the second fixed frame 2, and the inner wall of the second fixed frame 2 is provided with a motion through hole that moves with the first connecting post 5 and the second connecting post 11.

[0032] In this embodiment, a fixing post 12 is also fixedly installed in the second fixing frame 2. The fixing post 12 passes through the first connecting post 5 and the second connecting post 11, and a compression spring 13 is sleeved on the outside of the fixing post 12. The second rack post 9 does not contact the compression spring 13 in the second fixing frame 2.

[0033] The compression spring 13 provides the mechanism with the ability to buffer and reset. When the first connecting post 5 and the second connecting post 11 move, they will compress the compression spring 13. When the driving component stops working, the compression spring 13 can help each component return to its initial position or play a certain buffering role, avoid hard collisions between components, reduce wear, extend the service life of the mechanism, and also help maintain the accuracy and stability of the mechanism after multiple uses.

[0034] In this embodiment, the second rack post 9 passes through the second connecting post 11 and is fixedly connected to the first connecting post 5. The second connecting post 11 has a through hole 18 that matches the second rack post 9, ensuring the stability of the second rack post 9 in the second fixed frame 2. A third rack post 15 is fixedly installed on one side of the second connecting post 11. Both the second rack post 9 and the third rack post 15 are meshed with the rotating gear 10. When the second rack post 9 moves, it will drive the first connecting post 5 to move in the second fixed frame 2. At the same time, the second rack post 9 will also drive the third rack post 15 to move through the rotating gear 10. The direction of movement of the third rack post 15 is opposite to the direction of movement of the second rack post 9, and it will drive the second connecting post 11 to move. When the first connecting post 5 and the second connecting post 11 move, they will both compress the compression spring 13.

[0035] In this embodiment, a toothed post 14 is provided on the outer surface of the rotating ring block 3. The toothed post 14 is meshed with the first rack post 8. When the first rack post 8 is meshed with the contact part of the rotating ring block 3, the first rack post 8 can drive the rotating ring block 3 to rotate, thus completing the locking function.

[0036] The first rack column 8, the second rack column 9, and the third rack column 15 all move simultaneously. However, the second rack column 9 and the third rack column 15 will first contact the rotating gear 10. After the first connecting column 5 and the second connecting column 11 have completed their movement, the first rack column 8 will mesh with the rack column 14 on the rotating ring block 3, and then drive the rotating ring block 3 to rotate.

[0037] This embodiment also discloses a smart lock, which is applied to the locking mechanism of the smart lock in the above embodiments.

[0038] The working principle of this embodiment is as follows: During use, the sliding plate 7 moves in the first fixed frame 1 via the telescopic cylinder 6. At the same time, the sliding plate 7 also moves in the second rack column 9 in the second fixed frame 2. When the second rack column 9 moves, it drives the first connecting column 5 to move in the second fixed frame 2. Simultaneously, the second rack column 9 also drives the third rack column 15 to move via the rotating gear 10. The direction of movement of the third rack column 15 is opposite to that of the second rack column 9, and it drives the second connecting column 11 to move. When the first connecting column 5 and the second connecting column 11 move, they both compress the compression spring 13.

[0039] When the first connecting post 5 and the second connecting post 11 move, they will cause the plug block 16 to separate from the plug slot 17 in the rotating ring block 3. Then, the first rack post 8 will contact the toothed post 14 on the rotating ring block 3 and drive the rotating ring block 3 to rotate, thereby achieving the unlocking function of the smart lock. Conversely, when the plug block 16 and the plug slot 17 of the rotating ring block 3 are connected, the locking function of the smart lock can be achieved.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
