[0054] Please refer to the attached document. Figures 1-8In this embodiment, the second winding wheel 231 is provided with a locking groove 231a, and the first pull wire connector of the second pull wire 233 is engaged in the locking groove 231a, so that the inner contour of the locking groove 231a restricts the first pull wire connector of the second pull wire 233, preventing the first pull wire connector of the second pull wire 233 from detaching from the second winding wheel 231. No screws, adhesives or complex mechanical locking structures are required. The second pull wire connector of the second pull wire 233 is engaged at the lower end of the slider 141, so that the first pull wire connector and the second pull wire connector of the second winding wheel 231 are respectively connected to the second winding wheel 231 and the slider 141, thereby facilitating the second winding wheel 231 to pull the slider 141 to slide relative to the guide rail 14 via the second pull wire 233.

[0055] Please refer to the attached document. Figures 6-8 In this embodiment, the motor mounting base 21 is provided with a third mounting part 212, and the motor module 22 is mounted on the third mounting part 212 and disposed on one side of the second winding wheel 231, so that the motor module 22 can be connected to the motor mounting base 21 through the third mounting part 212, thus ensuring the positional accuracy of the motor module 22; the motor module 22 is arranged in an L-shape to reduce the space occupied between the motor module 22 and the motor mounting base 21.

[0056] Please refer to the attached document. Figures 6-8 In this embodiment, the motor module 22 includes a power motor 221 and a gear and worm gear transmission module 222. The gear and worm gear transmission module 222 is mounted on the third mounting part 212. One end of the gear and worm gear transmission module 222 is connected to the output end of the power motor 221, and the other end is connected to the second winding wheel 231. This allows the power output by the power motor 221 to be transmitted to the second winding wheel 231 via the gear and worm gear transmission module 222, thereby facilitating the automatic rotation of the second winding wheel 231 through the cooperation of the power motor 221 and the gear and worm gear transmission module 222. The power motor 221 and the second winding wheel 231 are stacked along the length of the motor mounting base 21, so that the power motor 221 and the second winding wheel 231 can make full use of the length space of the motor mounting base 21, reducing the width space occupied by the motor mounting base 21.

[0057] Please refer to the attached document. Figures 3-5In this embodiment, the guide rail 14 is connected to a slider 141; the third pull wire connector of the first pull wire 232 is engaged with the upper end of the slider 141 so that the slider 141 restricts the position of the third pull wire connector of the first pull wire 232 and prevents the third pull wire connector of the first pull wire 232 from disengaging from the upper end of the slider 141. The end of the first pull wire 232 away from the third pull wire connector is connected to the second winding wheel 231 so that the first pull wire 232 is connected to the upper end of the slider 141 and the second winding wheel 231 respectively, thereby facilitating the second winding wheel 231 to pull the slider 141 to slide relative to the guide rail 14 via the first pull wire 232.

[0058] Please refer to the attached document. Figure 5 In this embodiment, the slider 141 is connected to a slider body 1411, a spring 1412, and two engaging portions 1413. The slider body 1411 is slidably connected to the guide rail 14 and supports the connecting rod 40. The spring 1412 and the two engaging portions 1413 are both housed within the slider body 1411. One engaging portion 1413 is located at the upper end of the slider 141 and is used to engage with the third pull wire connector of the first pull wire 232. The other engaging portion 1413 is located at the lower end of the slider 141 and is used to engage with the second pull wire connector of the second pull wire 233. The spring 1412 applies pressure to the two engaging portions 1413. The elastic force allows the two engaging parts 1413 and the spring 1412 to restrict the position of the third pull wire connector of the first pull wire 232 and the second pull wire connector of the second pull wire 233, preventing the third pull wire connector of the first pull wire 232 and the second pull wire connector of the second pull wire 233 from disengaging from the slider body 1411. When the spring 1412 is compressed under the action of external force, the two engaging parts 1413 disengage from the third pull wire connector of the first pull wire 232 and the second pull wire connector of the second pull wire 233, thereby enabling the disassembly of the third pull wire connector of the first pull wire 232 and the second pull wire connector of the second pull wire 233.

[0059] At this time, when the drive motor module 22 rotates in reverse (counterclockwise), the second pull wire 233 is released, the first pull wire 232 is wound and tightened, the slider 141 slides along the guide rail 14, and the curtain 13 is opened; when the drive motor module 22 rotates in the forward direction (clockwise), the second pull wire 233 is wound and tightened, the first pull wire 232 is released, the slider 141 slides along the guide rail 14, and the curtain 13 is wound up. This is one cycle of opening and winding up the curtain 13.
