The first driving assembly 140 is connected with the rotating assembly 130 for driving the rotating assembly 130 to rotate, and the bearing piece 150 is arranged on the rotating assembly 130 and rotates with the rotating assembly 130.

[0046] When the curtain is unfolded, the carrier 150 is rotated above the curtain guide and carries the curtain rings to be arranged on the curtain guide; when the curtain is folded, the carrier 150 is rotated below the curtain guide and is inserted into the curtain rings.

[0047] The curtain opener 100 provided by the embodiment of the present application is provided with the hanging component 120 on the main machine 110, which is used for being hung on the curtain guide and can drive the curtain to move along the curtain guide. The first driving assembly 140 is connected with the rotating assembly 130 to drive the rotating assembly 130 to rotate on the hanging component 120 or the main machine 110, thereby driving the carrier 150 arranged on the rotating assembly 130 to rotate synchronously with the rotating assembly 130.

[0048] Thus, when the curtain needs to be unfolded, the rotating assembly 130 is driven by the first driving assembly 140 to rotate to drive the carrier 150 to rotate above the curtain guide, so as to carry the curtain rings in the unfolding process, which is beneficial to the curtain rings to be arranged on the curtain guide, thereby avoiding the technical problem that the curtain rings are inclined in the unfolding movement process to increase the friction between the curtain rings and the curtain guide, which affects the smoothness of the unfolding movement of the curtain rings and the hanging component 120 along the curtain guide.

[0049] When the curtain needs to be folded, the rotating assembly 130 is driven by the first driving assembly 140 to rotate to drive the carrier 150 to rotate below the curtain guide, so as to facilitate the carrier 150 to be inserted into the curtain rings in sequence in the folding process, thereby facilitating the folding of the curtain.

[0050] As shown in Figure 2 , Figure 3 and Figure 4 , in an embodiment of the present application, the first driving assembly 140 includes a first driving motor 141 and a first driving wheel 142, the first driving motor 141 is arranged on the hanging component 120 or the main machine 110, and the first driving wheel 142 is fixedly connected to the output end of the first driving motor 141 and is driven to rotate by the first driving motor 141.

[0051] In the embodiment, the first driving motor 141 is arranged on the hanging component 120 or the main machine 110, the first driving wheel 142 is fixedly connected to the output end of the first driving motor 141 and is driven to rotate by the first driving motor 141, so as to drive the rotating assembly 130 to rotate relative to the hanging component 120 or the main machine 110 under the connection action of the first driving wheel 142 and the rotating assembly 130, thereby driving the carrier 150 arranged on the rotating assembly 130 to rotate synchronously with the rotating assembly 130.

[0052] As shown in Figure 2 , Figure 3 and Figure 4As shown in the above embodiments of this application, the outer peripheral wall of the first drive wheel 142 is provided with a first toothed portion 1421; the inner peripheral wall or the outer peripheral wall of the rotating assembly 130 is provided with a second toothed portion 131 that meshes with the first toothed portion 1421.

[0053] In this embodiment, a first toothed portion 1421 is provided on the outer peripheral wall of the first drive wheel 142, and a second toothed portion 131 is provided on the inner or outer peripheral wall of the rotating assembly 130 to mesh with the first toothed portion 1421. Under the meshing connection of the first toothed portion 1421 and the second toothed portion 131, the rotating assembly 130 and the bearing member 150 are rotated relative to the hanging member 120 or the main unit 110.

[0054] like Figure 2 and Figure 4 As shown, in the above embodiments of this application, the rotating component 130 has an annular structure, which is used to be sleeved on the outer circumference of the curtain guide, and the second toothed part 131 is provided on the inner circumferential wall of the annular structure.

[0055] In this embodiment, the rotating component 130 has an annular structure, which is used to fit around the outer circumference of the curtain guide. By setting the second toothed part 131 on the inner circumferential wall of the annular structure, that is, the first drive wheel 142 is set on the inner circumferential direction of the rotating component 130 and meshes with the second toothed part 131 on the inner circumferential wall of the annular structure, it is beneficial to reduce the overall volume of the curtain opener 100 and make the structure of the curtain opener 100 simple and compact.

[0056] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the mounting member 120 or the host 110 is provided with a mounting member 121, and the rotating component 130 is rotatably disposed on the mounting member 121. The mounting member 121 is provided with a sliding guide rail 1211 that is adapted to the shape of the rotating component 130, and the rotating component 130 is slidably connected to the sliding guide rail 1211.

[0059] In the embodiment, by pivotally connecting the connecting member 160 with the rotating assembly 130 and the carrier 150 respectively, the carrier 150 is always close to the curtain guide during the rotation of the rotating assembly 130, so that the carrier 150 is prevented from being separated from the curtain guide, and the carrier 150 is ensured to carry the curtain rings during the unfolding of the curtain and to be inserted into the curtain rings in sequence during the folding of the curtain.

[0060] As shown in the drawings, Figure 2 and Figure 4 in any one of the above embodiments of the present application, the side wall of the carrier 150 is inclined from the end close to the rotating assembly 130 to the end away from the rotating assembly 130, so that the curtain rings are sequentially sleeved on the carrier 150 during the rotation of the rotating assembly 130.

[0061] In the embodiment, by inclining the side wall of the carrier 150 from the end close to the rotating assembly 130 to the end away from the rotating assembly 130, the side wall of the carrier 150 sequentially contacts with the curtain rings during the rotation of the carrier 150 from below the curtain guide to above the curtain guide, so that the side wall of the carrier 150 is prevented from simultaneously contacting with the curtain rings, which causes the increase of the rotating friction and the need of the first driving assembly 140 to overcome a larger torque, thereby causing the technical problem of high energy consumption of the curtain opener 100.

[0062] For example, the transverse cross-sectional area of the carrier 150 gradually increases along the direction away from the rotating assembly 130.

[0063] As shown in the drawings, Figure 3 and Figure 4 in any one of the above embodiments of the present application, the side of the carrier 150 away from the curtain guide is provided with an arc-shaped supporting surface 151 for carrying the curtain rings, and the side of the carrier 150 close to the curtain guide is provided with an arc-shaped groove 152 matched with the shape of the curtain guide.

[0064] In the embodiment, the arc-shaped supporting surface 151 for bearing the curtain ring is arranged on the side of the bearing member 150 away from the curtain guide, so as to adapt to the arc-shaped inner wall of the curtain ring, thereby facilitating the bearing stability of the curtain ring. Meanwhile, the arc-shaped groove 152 is arranged on the side of the bearing member 150 close to the curtain guide, so as to increase the contact area between the bearing member 150 and the curtain guide, thereby facilitating the bearing member 150 to be close to the curtain guide and rotate along the curtain guide.

[0065] As shown in Figure 1 and Figure 2 In any one of the above embodiments of the present application, the host 110 is further provided with a second driving assembly 111, which comprises a second driving motor 1111 and a second driving wheel 1112. The second driving wheel 1112 abuts against the outer circumferential wall of the curtain guide, and the second driving motor 1111 is used to drive the second driving wheel 1112 to rotate, so as to move the curtain opener 100 along the curtain guide.

[0066] In the embodiment, the host 110 is provided with the second driving motor 1111 and the second driving wheel 1112. The second driving wheel 1112 abuts against the outer circumferential wall of the curtain guide, and the second driving motor 1111 is used to drive the second driving wheel 1112 to rotate, so as to make the second driving wheel 1112 rollingly contact with the outer circumferential wall of the curtain guide, thereby driving the whole curtain opener 100 to move along the curtain guide, so as to realize the function of unfolding or folding the curtain.
