[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Reference Figures 1 to 5 A preferred embodiment of the clutch assembly of the present invention comprises: a rotatable first paddle 10, on which a clutch member 40 is movably provided; a driving device 30, used to drive the clutch member 40 to move relative to the first paddle 10 to switch between an engaged position and a disengaged position; a rotatable second paddle 20, on which a first clutch portion 21 is provided; one of the first paddle 10 and the second paddle 20 is an active member that can be driven to rotate by an external force, and the other is a driven member; when the clutch member 40 is in the engaged position, as the active member rotates, the clutch member 40 and the first clutch portion 21 can abut against each other to drive the driven member to rotate with the active member; when the clutch member 40 is in the disengaged position, during the rotation of the active member, the clutch member 40 and the active member remain staggered. In the clutch assembly of the present invention, the driving device 30 can drive the clutch member 40 to move on the first paddle 10 to achieve engagement and separation with the first clutch portion 21 on the second paddle 20, that is, the clutch of the first paddle 10 and the second paddle 20 can be controlled thereby. The structure is simple and reliable, and it also helps to reduce the volume of the clutch assembly, making it easy to process, manufacture and assemble. In addition, in the clutch assembly, the clutch member 40 is movably installed on the first paddle 10. In application, the clutch member 40 can be prevented from contacting the lock housing of the electronic lock, and it is not easy to get stuck or move smoothly, which can effectively reduce the failure rate and is more reliable.

[0036] As a preferred embodiment of the clutch assembly in the present invention, it may also have the following additional technical features:

[0037] In this embodiment, the first paddle 10 and the second paddle 20 are both flat-plate-shaped, and the first clutch portion 21 is a raised portion of the side edge of the second paddle 20. At the same time, the first paddle 10 and the second paddle 20 are close to each other, which can further reduce the thickness and volume of the clutch assembly.

[0038] In this embodiment, the second paddle 20 serves as an active member, and the first paddle 10 serves as a passive member. In other embodiments, the two may be interchangeable.

[0039] Reference Figures 1 to 3 In this embodiment, a sliding hole 11 is provided on the first paddle 10, and a sliding portion 41 is provided on the clutch member 40. The sliding portion 41 is slidably provided in the sliding hole 11 so that the clutch member 40 can be movably provided on the first paddle 10, which can further simplify the structure of the clutch assembly and facilitate processing and assembly. In other embodiments, the clutch member 40 can also be movably provided on the first paddle 10 through other common structures such as a sliding rod mechanism, a sliding rail mechanism, etc., and is not limited thereto.

[0040] The clutch member 40 is provided with two limit grooves 42 respectively located on both sides of the sliding portion 41. The two limit grooves 42 are respectively adapted to the two side edges of the sliding hole 11, and the two side edges of the sliding hole 11 are respectively inserted into the two limit grooves 42. The two limit grooves 42 can limit the clutch member 40 to prevent the clutch member 40 from loosening, which can effectively reduce the failure rate, and the structure is simple and reliable, which is convenient for processing and assembly.

[0041] Reference Figures 1 to 5 In this embodiment, the driving device 30 includes a driving motor 31 and a lever 32. The lever 32 has a toggle section that is slidably connected to the clutch 40. The toggle section is arc-shaped and its central axis coincides with the rotation axis of the first paddle 10. The driving motor 31 is used to drive the lever 32 to move so that the lever 32 pushes the clutch 40 to move. During the rotation of the first paddle 10, the clutch 40 can slide along the arc-shaped toggle section, so that the clutch 40 can be maintained in the engaged position, is not easily misaligned, and can effectively improve the reliability of the clutch assembly.

[0042] In this embodiment, the toggle section is an arc-shaped toggle plate 321, and the clutch 40 is provided with a toggle groove 43 adapted to the toggle plate 321. The toggle plate 321 is inserted into the toggle groove 43 to slide the lever 32 and the clutch 40. The structure is simple and easy to process and assemble. In other embodiments, the toggle section can also be connected to the clutch 40 using other common structures such as a slide rod structure, a slide rail structure, etc., and is not limited thereto.

[0043] In other embodiments, the driving device 30 may also use other suitable structures such as a gear rack mechanism driven by a motor, a connecting rod structure, etc. to drive the clutch member 40 to move, but is not limited thereto.

[0044] The driving device 30 also includes an elastic member, and the driving motor 31 drives the lever 32 to move through the elastic member. In the event of an unexpected situation, the elastic member can also play a buffering role. For example, when the clutch 40 is in the disengaged position, the second paddle 20 has rotated so that the first clutch portion 21 is aligned with the clutch 40. At this time, if the driving motor 31 is started, the clutch 40 will laterally abut against the first clutch portion 21. In this case, the elastic member can absorb the driving force of the driving motor 31 to prevent the driving device 30 from getting stuck and damaged. In addition, the elastic member also has a force storage function. When the movement of the lever 32 is obstructed due to dust blockage, aging, rust and other factors, as the driving motor 31 continues to drive, the elastic member can store force and gradually increase the driving force on the lever 32, so that the lever 32 can automatically overcome the obstacles under certain conditions and complete the clutch action, thereby having a stronger fault self-elimination capability.

[0045] In this embodiment, the driving device 30 further comprises a driving rod 33, the elastic member is a spring 34, the spring 34 is mounted on the lever 32, the driving rod 33 is inserted in the spring 34 and is driven by the driving motor 31 to rotate, and a driving column 331 with a lateral protrusion is provided on the driving rod 33 and inserted between two adjacent sections of the spring 34, so that when the driving motor 31 rotates the driving rod 33, the driving column 331 can drive the lever 32 to move through the spring 34, which can simplify the structure of the driving rod 33 and the lever 32 and facilitate processing. In other embodiments, the driving motor 31 can also use other commonly used elastic members such as spring pads and elastic pull ropes to drive the lever 32 to move, or the driving device 30 can also use other commonly used structures such as screw transmission mechanisms and gear rack mechanisms to drive the lever 32 to move, but it is not limited thereto. In addition, in this embodiment, the driving motor 31 is connected to the driving rod 33 through a gear transmission group 35, which can provide a larger output torque and is more reliable and practical.
