[0002] Smart locks are different from traditional mechanical locks. They are smarter and more user-friendly in terms of user security, identification, and management. Currently, smart split locks on the market generally use electromagnetic push rods to push the clutch assembly to control the lock tongue device to unlock or lock. When vibrations are generated perpendicular to the direction of the door, the electromagnetic push rod will erroneously move. When an erroneous movement occurs, the electromagnetic push rod will directly cause the handle to be linked with the lock tongue device. At this time, turning the handle can directly unlock the door, which is not very safe. Summary of the invention

The control device is electrically connected to the driving device 30 and can control the driving device 30 to rotate.

[0032] When the control device controls the driving device 30 to rotate, the threaded transmission structure pushes the clutch block 22 to move toward the rotating seat 21.

The threaded hole 41 is provided on one of the clutch block 22 and the driving device 30, and the threaded column 42 is provided on the other of the clutch block 22 and the driving device 30.

[0036] The clutch block 22 and the driving device 30 are threadedly connected via a threaded hole 41 and a threaded column 42. When the control device controls the driving device 30 to rotate, the driving device 30 pushes the clutch block 22 to move toward the rotating seat 21. After the clutch block 22 reaches the extreme position connected to the rotating seat 21, the threads between the threaded hole 41 and the threaded column 42 are disengaged, and the rotation of the driving device 30 will not drive the clutch block 22, and the driving device 30 will not be blocked.

[0037] In the embodiment of the present invention, the clutch block 22 reaches the limit position connected with the rotating seat 21 means that the first transmission part 221 enters the maximum rotation range of the first limit part 211, and the clutch block 22 is tightly connected with the rotating seat 21.

When the control device controls the driving device 30 to rotate, the driving device 30 pushes the clutch block 22 to move toward the rotating seat 21 , and the threaded hole 41 and the threaded column 42 are threadedly connected.

[0041] Threaded transmission structure embodiment 2: A threaded column 42 is provided in the guide groove 222, and a threaded hole 41 is provided on the driving device 30. When the control device controls the driving device 30 to rotate, the driving device 30 pushes the clutch block 22 to move toward the rotating seat 21, and the threaded hole 41 is threadedly connected to the threaded column 42. The guide groove 222 can guide the threaded transmission structure between the driving device 30 and the clutch block 21.

[0042] In some embodiments, a first elastic member 51 is provided between the rotating seat 21 and the clutch block 22. When the control device controls the driving device 30 to rotate, and the driving device 30 pushes the clutch block 22 to move toward the rotating seat 21, the first elastic member 51 is provided to ensure that when the clutch block 22 is at the extreme position connected with the rotating seat 21, the first elastic member 51 is further compressed, and the control device controls the driving device 30 to rotate, and the driving device 30 pulls the clutch block 22 back again, and uses the restoring force of the first elastic member 51 to drive the clutch block 22 to restore to its original state, and the first transmission part 221 is away from the rotation range of the first limit part 211.

[0043] Reference Figure 2 and Figure 3 As shown, in some embodiments, a baffle 52 is provided between the first elastic member 51 and the clutch block 22, one end of the first elastic member 51 abuts against the baffle 52, and the other end of the first elastic member 51 abuts against the rotating seat 21. A baffle 52 is provided between the first elastic member 51 and the clutch block 22, so that when the first elastic member 51 is reset, the first elastic member 51 pushes the clutch block 22 to move away from the rotating seat 21 by pushing the baffle 52, and the first transmission part 221 is away from the rotation range of the first limiting part 211.

[0044] Reference Figure 2 and Figure 3 As shown, in some embodiments, a second elastic member 60 is disposed between the clutch block 22 and the driving device 30 , one end of the second elastic member 60 abuts against the driving device 30 , and the other end of the second elastic member 60 abuts against the clutch block 22 .

[0045] When the control device controls the driving device 30 to rotate, the driving device 30 pushes the clutch block 22 to move toward the rotating seat 21. Since a second elastic member 60 is provided between the clutch block 22 and the driving device 30, it is further ensured that when the clutch block 22 is in the extreme position connected with the rotating seat 21, the threaded hole 41 of the threaded transmission structure and the threaded column 42 are threadedly connected without slipping.

[0046] In the embodiment of the present invention, the first elastic member 51 and the second elastic member 60 are both compression springs.

[0047] Reference Figure 3 As shown, in some embodiments, the clutch block 22 is provided with a second transmission part 223, the rotating seat 21 is provided with a second limiting part 212 facing the second transmission part 223, the second transmission part 223 is longer than the first transmission part 221, the second limiting part 212 is higher than the first transmission part 221, and there is a spacing between the first limiting part 211 and the second limiting part 212;

[0048] The second transmission part 223 is located in the rotation range of the second limiting part 212 . When the handle 10 is reversed, the second transmission part 223 can drive the second limiting part 212 to rotate, so that the rotating seat 21 can follow the handle 10 to reverse.

[0049] Since there is a gap between the first limiting portion 211 and the second limiting portion 212 , the width of the gap can accommodate the insertion of the first transmission portion 221 and the second transmission portion 223 .

[0050] When the control device controls the driving device 30 to rotate, the driving device 30 pushes the clutch block 22 toward the rotating seat 21 through the threaded transmission structure. When the first transmission part 221 and the second transmission part 223 are both inserted into the spacing, the first transmission part 221 enters the rotation range of the first limiting part 211, and the first transmission part 221 drives the first limiting part 211, and the rotating seat 21 follows the handle 10 to rotate forward to unlock the lock tongue device, thereby completing the unlocking.

[0051] When the handle 10 is reversed, the second transmission part 223 can drive the second limiting part 212 to rotate, so that the rotating seat 21 can follow the handle 10 to reverse, thereby completing the locking; in addition, the second transmission part 223 and the second limiting part 212 are connected, and are always located in the rotation range, which can guide the movement of the clutch block 22 and limit the rotational misalignment of the rotating seat 21 relative to the clutch block 22.

[0052] Reference Figure 1 , Figure 2 as well as Figure 3As shown, in some embodiments, the rotating seat 21 has an annular groove 213, and the handle 10 is installed with a fastener 70, which extends into the groove 213. The fastener 70 extends into the groove 213, limiting the relative position of the rotating seat 21 and the handle 10, so that the rotating seat 21 can only rotate relative to the handle 10.

[0053] In the embodiment of the present invention, the fastener 70 is a screw, a pin, etc.

[0054] In the embodiment of the present invention, a mounting hole 214 for mounting the locking tongue device is provided on the rotating seat 21 .

[0055] In the embodiment of the present invention, when the user does not have the authority to open the door, the clutch block 22 is brought back by the driving device 30, and the handle 10 rotates in the opposite direction. The second transmission part 223 on the clutch block 22 drives the second limit part 212 on the rotating seat 21 to lock it; when the handle 10 rotates forward, the second transmission part 223 on the clutch block 22 leaves the rotation range of the second limit part 212 on the rotating seat, and the first transmission part 221 on the clutch block 22 cannot touch the first limit part 211 on the rotating seat 21, so the rotating seat 21 does not rotate and cannot be unlocked.

[0056] At the same time, the present invention also provides a door lock, comprising the above-mentioned handle clutch structure.

[0057] A handle clutch structure is installed on the door lock. Since a threaded transmission structure is provided between the driving device 30 and the clutch block 22, when the control device controls the driving device 30 to rotate, the threaded transmission structure then pushes the clutch block 22 to move toward the rotating seat 21. The first transmission part 221 on the clutch block 22 enters the rotation range of the first limiting part 211, and the first transmission part 221 drives the first limiting part 211, and the rotating seat 21 follows the handle to rotate forward to unlock the lock tongue device, thereby completing the unlocking and then opening the door.

[0058] After unlocking, the control device driving device 30 rotates, the driving device 30 pulls the clutch block 22 back again, the first transmission part 221 leaves the first limit part 211, and the rotating seat 21 stops rotating. When vibration is generated in the direction perpendicular to the door, it can avoid erroneous unlocking or locking actions, and has a very strong axial anti-vibration ability; at the same time, the clutch assembly is arranged in the installation channel of the handle, and there is no need to arrange the clutch assembly in the panel, which can simplify the structure and volume of the panel and has higher safety.

[0059] The above embodiments are only preferred embodiments of the present invention, and the present invention may have other embodiments.
