[0028] The magnetic bead clutch assembly 30 and the dial clutch assembly 20 are transmission connected, one of the magnetic bead clutch assembly 30 and the dial clutch assembly 20 and the reduction assembly 40 are transmission connected, including two layout modes: one is that the magnetic bead clutch assembly 30 and the reduction assembly 40 are connected, and the dial clutch assembly 20 and the magnetic bead clutch assembly 30 are transmission connected; and two is that the dial clutch assembly 20 and the reduction assembly 40 are connected, and the dial clutch assembly 20 and the magnetic bead clutch assembly 30 are transmission connected.

[0029] The dial clutch assembly 20 slides to change the transmission position to disconnect or connect the transmission path of the reduction assembly 40 or the magnetic bead clutch assembly 30.

[0030] The magnetic bead clutch assembly 30 and the dial clutch assembly 20 are transmission connected and arranged, both of which can disconnect the transmission path. The magnetic bead clutch assembly 30 adopts the principle of the magnetic bead 33 clutch mechanism to realize the on-off control of the transmission path, and the magnetic bead clutch assembly 30 can manually accelerate during the transmission movement and keep the continuity of the transmission path.

[0031] Optionally, the magnetic bead clutch assembly 30 is used for connecting a chain mechanism 60 to drive the chain mechanism 60 to extend and retract.

[0032] The dial clutch assembly 20 can drive part of the transmission members in the transmission path to be separated from the transmission path, so that the dial clutch assembly 20 can manually disconnect the transmission path, and the manual rapid opening and closing of the window can be realized. The double clutch transmission mechanism can realize the acceleration opening and closing in the complete state of the transmission path, and also has a manual operation in an emergency situation, greatly improving the use function experience of the window opener.

[0033] In an embodiment, the dial clutch assembly 20 comprises a dial part 21, a clutch gear 23 and a fixed gear 22, the fixed gear 22 is installed in a shell 10, the clutch gear 23 is slidingly connected in the shell 10, and the dial part 21 moves along the axis direction of the fixed gear 22 to make the clutch gear 23 and the fixed gear 22 mesh or disconnect.

[0034] The gear 22 is installed on the casing 10 through a fixed shaft 26, and the rotating range of the gear 22 is fixed. The shifting part 21 is slidingly connected to the fixed shaft 26. The shifting range of at least part of the shifting part 21 coincides with the gear 23, so that the shifting part 21 drives the gear 23 to slide during the sliding process. When the gear 23 slides away from the gear 22, the transmission path is disconnected; when the gear 23 slides to engage with the gear 22, the transmission path is connected.

[0035] The shifting part 21 comprises a shifting rod 211 and a shifting block 212, and the shifting rod 211 is fixedly connected to the shifting block 212. The shifting block 212 and the shifting rod 211 are detachably connected, for example, the shifting rod 211 is connected to the shifting block 212 through interference insertion; or the shifting rod 211 is connected to the shifting block 212 through screw connection. Alternatively, the shifting block 212 and the shifting rod 211 are in an integrated structure.

[0036] A sliding groove 15 is formed on the casing 10, and the sliding groove 15 has a long slot structure. The shifting rod 211 extends out of the sliding groove 15, and the length range of the sliding groove 15 can limit the sliding range of the shifting block 212.

The end of the shifting rod 211 slides along the fixed shaft 26 under the shifting force of the user, and the part of the shifting block 212 extending into the ring groove 221 pushes the groove wall of the ring groove 221, thereby driving the gear 23 to move, so as to realize manual clutch control.

[0038] Preferably, the shifting block 212 is provided with a shifting protruding rib 2121 on the side, and the shifting protruding rib 2121 at least partially extends into the ring groove 221.

[0039] As a preferred, a first elastic member 24 is arranged between the shifting block 212 and the casing 10, and the restoring force direction of the first elastic member 24 is parallel to the sliding direction of the shifting block 212. The first elastic member 24 is a spring, specifically, the first elastic member 24 is a compression spring or a tension spring, so that the shifting block 212 has an elastic restoring force after shifting and compressing the first elastic member 24.

[0040] Preferably, the shifting block 212 drives the gear 23 to move towards the gear 22 under the elastic force of the first elastic member 24, so as to realize the conduction of the transmission path.

[0042] The second elastic member maintains the elastic pre-tightening force of the pushing clamping bead 25 protruding outwardly towards the groove, and the groove provides a containing space for the clamping bead 25 to move inwardly of the knob 212. During the sliding process of the knob 212, extrusion is formed between the clamping bead 25 and the casing 10, and when the clamping bead 25 moves to the clamping groove, the resistance to the movement of the knob 212 along the casing 10 is increased, thereby achieving positioning. When the knob 212 is subjected to a pushing force greater than the resistance, the knob 212 can continue to slide along the fixed shaft 26 to move to the direction of another clamping groove, thereby achieving manual positioning of the disconnection and conduction of the transmission path.

At this time, if the chain mechanism 60 is pushed by an external force, the output member 31 will be rotated, the clutch member 34 will not be rotated, and manual acceleration is achieved.

[0046] In the rotating state of the transmission gear 32, the transmission gear 32 drives the clutch member 34 to rotate, and under the action of centrifugal force, the magnetic beads 33 will move, and part of the magnetic beads 33 will be embedded in the groove, thereby causing the clutch member 34 and the magnetic beads 33 to be clamped, and the rotation of the clutch member 34 will drive the output member 31 to rotate, so that the output of the transmission gear 32 is transmitted to the output member 31.
