Description

Technical Field

[0001] This utility model relates to the field of clutch device technology, and in particular to a clutch device with an anti-shaking structure. Background Technology

[0002] While there are many types of clutch mechanisms available for smart locks, most products do not prioritize the compatibility between the handle and the clutch mechanism. This design flaw directly leads to handle wobbling and causes multiple negative impacts.

[0003] First, from a user perspective, a wobbly handle severely impacts the user's experience of opening and closing the door. Second, from the perspective of lock lifespan, each time the user operates the lock, the wobbly handle and the transmission rod will experience "misaligned force" instead of a vertical and stable force. Over time, this will accelerate the wear of the transmission rod, causing rod deformation, stripped screws at the connection points, and other malfunctions, significantly shortening the lifespan of the smart lock. More importantly, there are potential security risks. Shaking the handle increases the gap between the lock cylinder and the handle. If pried open by external force, the loosened structure will significantly reduce the lock's resistance to damage, increasing the probability of it being cracked and posing a threat to home security. Solving the compatibility issue between the handle and the clutch mechanism has become an important direction for the optimization of smart locks.

[0004] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0018] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0019] like Figure 1-11 As shown, this embodiment provides a clutch device with an anti-shake structure, including a lock cover 1, an outer door handle connector 2, an anti-shake structure 3, a rotation reset structure 4, a rotating component 5, an inner connector 6, and a cover plate 7. The lock cover 1 and the cover plate 7 are installed together. An outer connecting hole 11 is provided on the lock cover 1. The anti-shake structure 3 is provided on the outer connecting hole 11. A card seat 21 is provided on the outer door handle connector 2. An outer connecting post 22 is provided at one end of the outer door handle connector 2 that extends into the outer connecting hole 11. The outer connecting post 22 passes through the anti-shake structure 3 and is connected to the lock cover 1. The outer connecting post 22 passes through one side of the lock cover 1 and is connected to the rotating component 5. The rotation reset structure 4 is provided between the rotating component 5 and the lock cover 1. The inner connector 6 is provided between the rotating component 5 and the cover plate 7. The anti-shake structure 3 includes a positioning ring 31 and a spring 32. The positioning ring 31 is formed by the inner flange of the outer connecting hole 11 towards the lock cover 1. The outer connecting post 22 passes through the positioning ring 31, and the spring 32 is sleeved on the outer connecting post 22 and slidably positioned between the outer connecting post 22 and the positioning ring 31. The positioning ring 31 increases the force-bearing height, making the handle less prone to shaking. Furthermore, it is integrally stamped, which not only makes the positioning ring 31 structurally stable, preventing malicious prying of the lock, but also ensures a smooth and straight connection between the positioning ring 31 and the outer connecting hole 11. The spring 32 creates rolling friction between the outer connecting post and the positioning ring, making it smoother for the user to turn the handle.

[0020] This invention proposes a clutch device with an anti-shake structure, which is mainly used in the field of smart locks. It can prevent door handles from shaking, which can not only extend the service life of the lock, but also improve security and user experience.

[0021] Furthermore, a pressure plate 33 and a washer 34 are fitted onto the outer connecting post 22. The pressure plate 33 is pressed between the card seat 21 and the lock cover 1, and the washer 34 is positioned between the bottom of the positioning ring 31 and the pressure plate 33. Because the connection between the positioning ring 31 and the outer connecting hole 11 is straight and smooth, the pressure plate 33 and the washer 34 fit more snugly between the card seat 21 and the lock cover 1. In particular, the pressure plate 33 effectively adjusts the clearance between the card seat 21 and the lock cover 1. Additionally, the pressure plate 33 is preferably made of manganese, and the washer 34 is preferably textured with a wave pattern.

[0022] Preferably, a spring positioning element 35 is provided on one end of the positioning ring 31 near the cover plate 7, and the spring positioning element 35 is inserted between the outer connecting post 22 and the positioning ring 31 to cooperate with the spring 32. The setting of the spring positioning element 35 restricts the range of motion of the spring 32, preventing the spring 32 from slipping away and affecting the connection between the outer connecting post 22 and the positioning ring 31.

[0023] Furthermore, the rotational reset structure 4 includes a rotational reset torsion spring 41, a clutch drive device 42, and a limiting structure 43. The rotational reset torsion spring 41 is located outside the positioning ring 31, the clutch drive device 42 is disposed below the rotational reset torsion spring 41, and the limiting structure 43 is connected to the rotational reset torsion spring 41 and is connected to the rotating component 5 by bolts. This arrangement allows the user to unlock the door by twisting the handle under the action of the clutch drive device 42.

[0024] Specifically, the limiting structure 43 includes a first limiting part 431, a second limiting part 432, and a third limiting part 433 disposed on the rotary reset torsion spring 41. A limiting block 12 is disposed on the side of the lock cover 1. The first limiting part 431 is placed on the limiting block 12. The second limiting part 432 is connected to the inner connecting member 6. A locking part 53 is disposed on the side of the rotating member 5 near the third limiting part 433. The third limiting part 433 is disposed below the locking part 53. The limiting structure 43 restricts the movement of the rotary reset torsion spring 41 within a certain range and facilitates the self-reset of the rotary reset torsion spring 41 after twisting.

[0025] Furthermore, abutment arms 61 are provided on both sides of the inner connecting member 6, which abut against the limiting structure 43 when rotated. A clutch hole 62 is provided on the lower side of the inner connecting member 6, and a clutch member 63 that can slide up and down is provided in the clutch hole 62. When the clutch driving device 42 drives the clutch member 63 to move upward in the clutch hole 62, the outer door handle connecting member 2 is rotated. The rotating member 5 rotates with the outer door handle connecting member 2, thereby driving the inner connecting member 6 to rotate. This configuration allows the user to easily turn the handle to open the door under the action of the clutch driving device 42.

[0026] Furthermore, the outer door handle connector 2 is longitudinally provided with a square shaft outer connecting hole 23, and the upper and lower sides of the outer connecting post 22 are provided with grooves 221 that connect with the square shaft outer connecting hole 23. The rotating part 5 is provided with a through hole 51 in the middle that allows the outer connecting hole 11 to be inserted, and a card 511 that matches the groove 221 is provided on the through hole 51 so that the outer door handle connector 2 can drive the rotating part 5 to move. A gasket 52 is provided between the outer connecting post 22 and the rotating part 5 to prevent the rotating part 5 from falling off.

[0027] Furthermore, the cover plate 7 and the outer connecting hole 11 are provided with an inner connecting hole 71 at the same axial height. The inner connecting member 6 also includes an inner connecting post 65. The inner connecting post 65 is provided with a square shaft inner connecting hole 64 in the middle. The square shaft inner connecting hole 64 is used to connect with the outer door handle connecting member 2. The inner connecting post 65 is inserted into the inner connecting hole 71.

[0028] In practical applications, a square rod (not shown in the figure) is installed on the outer connecting hole 23 and the inner connecting hole 64 of the square shaft. The square rod passes through the lock body (not shown in the figure) and connects to the inner door handle (not shown in the figure), thereby enabling the unlocking of the inner or outer door.

[0029] Preferably, the clutch drive device 42 includes a limiting fork 421, and the clutch drive device 42 can drive the clutch element 63 to slide on the limiting fork 421. This arrangement makes the clutch structure more reliable, the clutch element 63 slides more smoothly, and the user's experience of opening / closing the lock is better.

[0030] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
