[0047] Example 1: As Figure 1-6 As shown, the clutch transmission device includes an input component 1 with an actuating part 11, a sleeve 2, a transmission assembly 3, and a ball bearing 12. The sleeve 2 is provided with an assembly opening 201 corresponding to the input component 1 and a through hole 202 communicating with the assembly opening 201. The sleeve 2 is fitted onto the input component 1 through the assembly opening 201, and the actuating part 11 is placed inside the assembly opening 201. The ball bearing 12 is assembled inside the through hole 202. The actuating part 11 is provided with a clearance part 110 to avoid the ball bearing 12. The transmission assembly 3 is assembled onto the sleeve 2 through a transmission groove 30. The transmission groove 30 is provided with a protrusion 301 corresponding to the ball bearing 12. When the input component 1 is rotated, the clearance part 110 is engaged. When the through hole 202 is misaligned, the ball bearing 12 is at least partially exposed through the through hole 202 into the sleeve 2. The portion of the ball bearing 12 exposed into the sleeve abuts against the protrusion 301, and is in a powered engagement state. When the input component 1 is rotated so that the relief part 110 is relative to the through hole 202, the ball bearing 12 is placed inside the sleeve 2. The clutch transmission device is assembled inside the curtain machine. When the clutch transmission device is in a powered disengaged state, the user can manually pull the curtain or the curtain's pull cord to open or close the curtain. When the clutch transmission device is in a powered engagement state, the curtain machine runs. The curtain can be opened or closed smoothly even if the curtain machine malfunctions, there is a power outage, or the power is exhausted, thus improving the flexibility and reliability of use.

[0048] The input component 1 is provided with an insertion groove 13, and the sleeve 2 is provided with an insertion part 21 corresponding to the insertion groove 13. The sleeve 2 is fitted onto the input component 1 through the cooperation of the insertion part 21 and the insertion groove 13. The insertion groove 13 is provided with a locking part 131 for driving the sleeve 2 to rotate. When in a powered engagement state, the insertion part 21 abuts against the locking part 131. The cooperation between the locking part and the insertion part enables the input component to drive the sleeve to rotate.

[0049] The system includes a motor 5, and the input component 1 is mounted on the output shaft of the motor 5. The motor 5 drives the input component 1 to rotate, thus the motor drives the input component to rotate.

[0050] The device includes a damping element 4 to prevent the sleeve from rotating when the power is disengaged. The damping element 4 abuts against the sleeve 2. When the locking part and the insertion part are not in contact, the clutch transmission device is in a power disengaged state. The damping element can prevent the sleeve from rotating. When the transmission component is driven by an external force, the damping element abuts against the sleeve so that the sleeve will not be driven to rotate by the rotation of the transmission component. This prevents the balls from being exposed on the sleeve and abutting against the protrusion of the transmission component, and prevents the power disengagement state of the clutch transmission device from becoming the power engagement state.

[0051] The damping element 4 includes an abutment 41 and an elastic element 42. One end of the abutment 41 abuts against the sleeve 2, and the elastic element 42 is assembled at the other end of the abutment 41. The elastic element applies pressure to the abutment, causing the abutment to press tightly against the sleeve. When the clutch transmission device is in a power disengagement state, the sleeve will not be driven to rotate by the rotation of the transmission component, thereby preventing the balls from being exposed outside the sleeve and changing the power disengagement state of the clutch transmission device to a power engagement state. When the clutch transmission device is in a power engagement state, the motor drives the input component to rotate, and the sleeve fitted on the input component rotates against the damping force of the damping element.

[0052] The outer wall of the sleeve 2 is provided with a damping groove 22 corresponding to the damping member 4. The damping member 4 abuts against the damping groove 22. The damping groove and the damping member cooperate to increase the friction force, which further prevents the sleeve from being driven to rotate by the rotation of the transmission component, thereby preventing the balls from being exposed on the sleeve and changing the power disengagement state of the clutch transmission device to the power engagement state.

[0053] Example 2: As Figure 1-15As shown, the curtain machine includes a housing 6 with an internal assembly space 61 and the clutch transmission device. The clutch transmission device is assembled inside the housing 6. The transmission assembly 3 includes a first gear 31. The housing 6 also has a second gear 62 meshing with the first gear 31 and a third gear 63 coaxial with the second gear 62. The housing 6 has an inlet 601 and an outlet 602 corresponding to the third gear 63. The curtain bead cord enters the housing 6 through the inlet 601, winds around the third gear 63, and then protrudes from the housing 6 through the outlet 602. When the clutch transmission device is in a power disengagement state, the user can manually pull the curtain bead cord to open or close the curtain. When the clutch transmission device is in a power engagement state, the curtain machine operates. The structure of this application allows the curtain to be opened or closed smoothly even when the curtain machine malfunctions, there is a power outage, or the power is exhausted, improving the flexibility and reliability of use.

[0054] The housing 6 has a first mounting hole 603 and a second mounting hole 604 on its two side walls for the beaded cord to enter. The first mounting hole 603 and the second mounting hole 604 are respectively connected to the inlet 601 and the outlet 602. The back of the curtain machine housing is installed on the window door. The beaded cord is inserted through the first mounting hole and exited through the inlet. Then the beaded cord is wound around the third gear and then inserted through the outlet and exited through the second mounting hole. The beaded cord is exposed at both ends of the curtain machine and installed at both ends of the window. The curtain machine can then be used as a window opener, and the operation of the curtain machine can be controlled to open or close the window door.

[0055] The device also includes a power supply 7, which is assembled within the assembly space 61. The assembly space 61 is provided with a push-button latch 64, and the power supply 7 is provided with a corresponding insertion post 71.

[0056] The housing 6 has a receiving groove 66 corresponding to the elastic member 42. The damping member 4 is assembled in the receiving groove 66 through the elastic member 42. One end of the elastic member 42 abuts against the abutting member 41, and the other end of the elastic member 42 abuts against the receiving groove 66. The receiving groove is provided so that the damping member can be assembled in the housing to apply a damping effect to the sleeve.

[0057] The transmission assembly 3 includes a base 32, a transmission groove 30 is disposed on the bottom surface of the base 32, a connecting shaft 321 is disposed on the base 32, and the first gear 31 is disposed on a connecting groove 311 corresponding to the connecting shaft 321. The first gear 31 is assembled on the base 32 through the cooperation of the connecting groove 311 and the connecting shaft 321, so that the first gear rotates together when the base rotates.

[0058] The system includes a magnetic component 621 and a Hall sensor 81. The magnetic component 621 is mounted on the second gear 62 and / or the third gear 63 and / or the clutch transmission device. The Hall sensor 81 is mounted inside the housing 6 and positioned opposite the magnetic component 621. The system also includes a circuit board 8, on which the Hall sensor 81 is mounted. The circuit board 8 is mounted inside the housing 6. When the Hall sensor 81 senses the rotation of the magnetic component, the motor 5 runs in the direction of rotation of the magnetic component, allowing the user to start the curtain motor by pulling the curtain cord.

[0059] Example 3: As Figure 1-26 As shown, the curtain machine includes a housing 6 with an internal assembly space 61 and the clutch transmission device. The top of the housing 6 is provided with a roller hole 67. The clutch transmission device is assembled inside the housing 6 and at least partially exposed through the roller hole 67. The portion of the clutch transmission device exposed in the housing allows the curtain machine to run on the curtain track. When the clutch transmission device is in a power disengagement state, the user can manually pull the curtain to open or close it. When the clutch transmission device is in a power engagement state, the curtain machine runs. The structure of this application allows the user to manually pull the curtain to open or close it smoothly when the curtain machine malfunctions, there is a power outage, or the power is exhausted, thus improving the flexibility and reliability of use.

[0060] This includes a roller sleeve 68, which is fitted onto the clutch transmission device, enabling the curtain machine to run more smoothly and without jamming on the curtain track.

[0061] The system includes a belt, the output shaft of the motor 5 is equipped with a drive pulley, the input component 1 is equipped with a driven pulley 14, one end of the belt is fitted onto the drive pulley, and the other end of the belt is fitted onto the driven pulley 14.

The mounting cover 44 is mounted in the first mounting hole 430 and located at the end away from the screw 45. The side of the mounting cover 44 away from the mounting component 43 is provided with an elastic element 42. When the clutch transmission device is in the power disengagement state, the sleeve will not be driven to rotate by the rotation of the transmission component, thereby preventing the balls from being exposed on the sleeve and changing the power disengagement state of the clutch transmission device to the power engagement state. When the clutch transmission device is in the power engagement state, the motor drives the input component to rotate, and the sleeve fitted on the input component rotates against the damping force of the damping element.

[0063] This includes a bearing 46, which is mounted on the sleeve 2.
