The end where the 224 is located swings (swings backward); in the third type, the two first electromagnets 224 are both de-energized, and the swinging member 223 is in a balanced state. Specifically, when the swing member 223 is in the first and second states, the second electromagnet 421 in the control arm 420 loses power, and the clutch 400 is disengaged from the scroll mechanism 100; at this time, the coil The curtain driver can perform electric driving; when the swing member 223 is in the third condition, the second electromagnet 421 in the control arm 420 is energized, the clutch 400 is engaged with the rolling mechanism 100, and the roller blind driver Manual drive can be performed.

The scroll mechanism 100 includes a square shaft 110 and a reel 120; the reel 120 is sleeved on the square shaft 110, and one end of the square shaft 110 is clamped with one end of the reel 120.

In this embodiment, the reel 120 is hollow, and one end of the square shaft 110 directly extends into the reel 120 to be clamped with one end of the reel 120, wherein the reel 120 is provided with an adapter The square hole of the square shaft 110 has a size, and the other end of the square shaft 110 protrudes from the other end of the reel 120.

The scroll mechanism 100 further includes a rotating body 130 that is fixedly connected to the reel 120, the rotating body 130 is provided with protruding teeth 131, and the bead plate 310 is provided corresponding to the protruding teeth 131 A groove into which the protruding teeth 131 can movably extend.

When the rotating body 130 rotates, the reel 120 rotates, so as to realize the retracting and unfolding of the curtain.

The outer wall of the bead plate 310 is provided with an annular groove 311, and a plurality of bead grooves 312 are evenly distributed on the annular groove 311.

The pull rod 422 is connected to the second electromagnet 421 through a spring. When the second electromagnet 421 is energized, the second electromagnet 421 is attracted to the permanent magnet or iron member on the pull rod 422, so that the pull rod 422 rises. At this time, the spring is compressed, and the pull rod 422 drives the crank arm 424 to move around. The inflection point of the crank arm 424 rotates. When the crank arm 424 rotates, the clutch body 410 is driven to move along the axial direction of the square shaft 110. The purpose is to make the clutch body 410 drive the bead plate 310 to move along the axial direction of the square shaft 110, thereby making the bead plate 310 is engaged with the rotating body 130.

If the bead plate 310 is to be separated from the rotating body 130, the second electromagnet 421 loses electricity, and the spring compression will naturally extend, prompting the pull rod 422 to descend, and driving the crank arm 424 around the crank arm 424. When rotating at the inflection point of the crank arm 424, the rotation of the crank arm 424 drives the clutch body 410 to move in the axial direction of the square shaft 110, and the bead disc 310 is disengaged from the rotating body 130.
