DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7The new intelligent lock clutch of the present invention includes a base plate 1 for mounting the clutch. The new intelligent lock clutch also includes: a motor assembly 6, a handle shaft 2, an idler lower cover 4, a gasket 11, a retaining spring 9, a torsion spring 10, a claw 8 and an idler upper cover 5 arranged along the axis AA of the clutch. Among them, 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 is inserted into the center hole of the base plate 1, and the handle shaft 2 is rotatable relative to the base plate 1. 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 the clutch plate 3. The motor assembly 6 can drive the clutch plate 3 to move forward and backward parallel to the axis AA. The front section 21 of the handle shaft 2 passes through the center through hole 42 of the idler lower cover 4, and the idler 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 idle-swing 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 bridge 41 is provided between the ends of the idle-swing upper cover 5 and the idle-swing lower cover 4, allowing the idle-swing upper cover 5 and the idle-swing lower cover 4 to span the base plate 1 and connect them together.

[0028] like Figure 6 As shown, 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 and rear sections 21, 22 of the handle shaft 2. On the surface of the annular step 23, near the side wall of the front section 21, parallel to the axis AA, a slide groove 24 is provided extending toward the rear section 22. The clutch plate 3 on the free end of the motor assembly 6 slides within the slide groove 24. A deep-opening retaining groove 25 is provided on the front end surface of the front section 21 of the handle shaft 2, along the axis AA toward the rear section 22. The retaining groove 25 cooperates with the inner protrusion on the inner ring of the claw member 8, allowing the claw member 8 and the handle shaft 2 to rotate synchronously.

[0029] like Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, a groove 51 is provided in the middle of the side of the idler cover 5 facing the idler lower cover 4, which is used 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 idler cover 5 away from the idler 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 idler cover 5 is connected to the bottom wall of the groove 51. A limiting notch 43 is provided on the wall of the central through hole 42 of the idler lower cover 4, perpendicular to the axis AA of the clutch. The slide groove 24 of the rear section 22 of the handle shaft 2 corresponds to the limiting notch 43 on the idler lower cover 4, allowing the clutch plate 3 to slide relatively within the slide groove 24 and the limiting notch 43.

[0030] like Figure 7 、 Figure 8 and Figure 9 As shown, screws 7 are provided between the ends of the upper and lower covers 5 and 4, respectively, to securely connect the upper and lower covers 5 and 4. It should be noted that the bridge piece 41 and the lower cover 4 of this embodiment are integrally formed, with the ends of the bridge piece 41 being fixedly connected to the ends of the upper and lower covers 5. The connection methods between the upper and lower covers 5 and 4 include, but are not limited to, the bridge piece 41 connection method. Any connection method between the upper and lower covers 5 and 4, as long as the upper and lower covers 5 and 4 span the base plate 1 and are connected, is within the scope of protection of the present invention.

[0031] like Figure 1 、 Figure 5 and Figure 10 As shown, the fixed end of the motor assembly 6 is mounted on the rear end of the rear section 22 of the handle shaft 2, and the free end of the motor assembly 6 is detachably connected to the clutch plate 3. The motor assembly 6 drives the clutch plate 3 to move forward and backward parallel to the axis. During use, when the motor assembly 6 drives the clutch plate 3 forward, the front portion of the clutch plate 3 moves from the chute 24 of the rear section 22 of the handle shaft 2 into the retaining notch 43 of the idle rotation lower cover 4. The clutch plate 3 connects the idle rotation lower cover 4 and the handle shaft 2 together. When the handle shaft 2 rotates, the idle rotation lower cover 4 and the idle rotation upper cover 5 rotate synchronously. The square rod connected to the idle rotation upper cover 5 also rotates synchronously, and the square rod drives the lock cylinder to rotate to unlock. When the motor assembly 6 drives the clutch plate 3 backward, the front portion of the clutch plate 3 completely exits the retaining notch 43 of the idle rotation lower cover 4. At this time, the handle shaft 2 is separated from the idle rotation lower cover 4 and the idle rotation upper cover 5, and the idle rotation lower cover 4 and the idle rotation upper cover 5 are in the idle rotation state. It should be noted that the specific structural form of the motor assembly 6 of this embodiment can be implemented using existing technologies, so it will not be described in detail herein.

[0032] The beneficial effects of the new intelligent lock clutch of this embodiment are as follows:

[0033] The clutch has a flat structure and high integration, which saves space. It also has a simple structure, is easy to install, and has low cost, so it has a wide range of applications.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
