[0029] 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.

[0030] Please refer to Figures 1, 2, 3, 4, 5, and 7. This novel intelligent lock clutch includes a base plate 1 for mounting the clutch. The clutch also includes a motor assembly 6, a handle shaft 2, a lower cover 4 for free rotation, a washer 11, a retaining ring 9, a torsion spring 10, a claw 8, and an upper cover 5 for free rotation, all arranged along the clutch axis AA. The handle shaft 2 has an integrally formed front section 21 and a rear section 22. The front section 21 of the handle shaft 2 passes through the central hole of the base plate 1, allowing the handle shaft 2 to rotate relative to the base plate 1. The fixed end of the motor assembly 6 is mounted at the rear end of the rear section 22 of the handle shaft 2. The free end of the motor assembly 6 is detachably connected to a clutch disc 3, enabling the motor assembly 6 to drive the clutch disc 3 to move back and forth parallel to the axis AA. The front section 21 of the handle shaft 2 passes through the central through hole 42 of the lower cover 4, and the lower cover 4 is located between the rear section 22 of the handle shaft 2 and the base plate 1, and is rotatably connected to the handle shaft 2. The upper cover 5 is located at the front end of the front section 21 of the handle shaft 2, and is used to transmit the torque of the handle shaft 2 to the lock cylinder. A bridging piece 41 is provided between the two ends of the upper cover 5 and the lower cover 4, so that the upper cover 5 and the lower cover 4 can cross the base plate 1 and be connected together.

[0031] As shown in Figure 6, the handle shaft 2 has an integrally formed front section 21 and rear section 22. The outer diameter of the front section 21 is smaller than that of the rear section 22. An annular step 23 is formed at the connection between the front section 21 and the rear section 22 of the handle shaft 2. On the surface of the annular step 23, near the side wall of the front section 21, a groove 24 is provided parallel to the axis line AA and extending towards the rear section 22. The clutch plate 3 on the free end of the motor assembly 6 slides in the groove 24. On the front end face of the front section 21 of the handle shaft 2, a deeply open slot 25 is provided along the axis line AA towards the rear section 22. The slot 25 cooperates with the inner protrusion on the inner ring of the claw 8, so that the claw 8 and the handle shaft 2 can rotate synchronously.

[0032] As shown in Figures 1, 6, 7, 8, and 9, a groove 51 is provided in the middle of the side of the upper cover 5 facing the lower cover 4 to avoid the distal end of the front section 21 of the handle shaft 2. A square hole 52 is provided in the middle of the side of the upper cover 5 away from the lower cover 4, along the axis AA. This square hole 52 is used to insert one end of a square rod, the other end of which is connected to the lock cylinder. The square hole 52 of the upper cover 5 and the bottom wall of the groove 51 are connected. A limiting notch 43 is provided on the wall of the central through hole 42 of the lower cover 4, perpendicular to the axis AA of the clutch. The sliding groove 24 of the rear section 22 of the handle shaft 2 corresponds to the limiting notch 43 on the lower cover 4, allowing the clutch plate 3 to slide relative to each other within the sliding groove 24 and the limiting notch 43.

[0033] As shown in Figures 7, 8, and 9, screws 7 are respectively provided between the two ends of the upper and lower covers 5 and 4, which are used to fix the upper and lower covers 5 and 4 together. It should be noted that in this embodiment, the bridge piece 41 and the lower cover 4 are integrally formed, and the end of the bridge piece 41 is fixedly connected to both ends of the upper cover 5. The connection method between the upper and lower covers 5 and 4 includes, but is not limited to, the connection method using the bridge piece 41. As long as the upper and lower covers 5 and 4 cross the base plate 1 and are connected, they are within the protection scope of this utility model.

[0034] As shown in Figures 1, 5, and 10, the fixed end of the motor assembly 6 is installed at the rear end of the rear section 22 of the handle shaft 2. The free end of the motor assembly 6 is detachably connected to a clutch plate 3. The motor assembly 6 drives the clutch plate 3 to move back and forth parallel to the axis. In use, when the motor assembly 6 drives the clutch plate 3 to move forward, the front part of the clutch plate 3 moves from the slide groove 24 of the rear section 22 of the handle shaft 2 to the limiting notch 43 of the lower cover 4. The clutch plate 3 connects the lower cover 4 and the handle shaft 2 together. When the handle shaft 2 rotates, it drives the lower cover 4 and the upper cover 5 to rotate synchronously. The square rod connected to the upper cover 5 also rotates synchronously. The square rod drives the lock cylinder to rotate, thereby unlocking the lock. When the motor assembly 6 drives the clutch plate 3 to move backward, the front part of the clutch plate 3 completely retracts from the limiting notch 43 of the idle-rotating lower cover 4. At this time, the handle shaft 2 separates from the idle-rotating lower cover 4 and the idle-rotating upper cover 5, and the idle-rotating lower cover 4 and the idle-rotating upper cover 5 are in an idle-rotating state. It should be noted that the specific structural form of the motor assembly 6 in this embodiment can be implemented using existing technology, so it will not be described in detail here.

[0035] The beneficial effects of this novel intelligent lock clutch in this embodiment are as follows:

[0036] The clutch has a flat structure, high integration, saves space, and is simple to install, with low cost, thus it has a wide range of applications.

[0037] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
