[0040] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0041] The driving structure of the sunshade curtain according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0042] As Figures 1-11 shown, the driving structure of the sunshade curtain according to an embodiment of the present invention includes a frame portion 20, a rotating assembly 30, a moving assembly 40, a first cable 51, a second cable 52, and a third cable 53.

[0043] The rotating assembly 30 is rotatably disposed on the frame portion 20. The rotating assembly 30 is adapted to wind the sunshade curtain 10. The moving assembly 40 is movably disposed on the frame portion 20 along a first direction to approach or move away from the rotating assembly 30. The moving assembly 40 is adapted to fix one end of the sunshade curtain 10 in the first direction.

[0044] Wherein, when the moving assembly 40 moves in a direction approaching the rotating assembly 30, the moving assembly 40 can drive the other end of the sunshade curtain 10 to move in a direction approaching the rotating assembly 30, thereby facilitating winding the sunshade curtain 10 on the rotating assembly 30. When the moving assembly 40 moves in a direction away from the rotating assembly 30, the rotating assembly 30 releases the sunshade curtain 10 wound thereon to deploy the sunshade curtain 10, thereby realizing the retraction and deployment of the sunshade curtain 10.

[0045] One end of the first cable 51 is fixed to the first end of the rotating assembly 30 in a second direction. The other end of the first cable 51 is connected to one side of the moving assembly 40 in the first direction. One end of the second cable 52 is fixed to the first end of the rotating assembly 30 in the second direction. The other end of the second cable 52 is connected to the other side of the moving assembly 40 in the first direction, so as to pull the moving assembly 40 away from the rotating assembly 30 when the rotating assembly 30 rotates in the reverse direction.

[0046] The third cable 53 is wound around the second end of the rotating assembly 30 in the second direction. One end of the third cable 53 is connected to one side of the moving assembly 40 in the first direction. The other end of the third cable 53 is connected to the other side of the moving assembly 40 in the first direction. Wherein, the second direction and the first direction are different directions.

[0047] For the convenience of description, the two sides in the first direction are referred to as the front side and the rear side here (it should be understood that the above direction definitions are only for facilitating the description of the drawings and will not limit the actual installation position and direction of the driving structure of the sunshade curtain). The rotating assembly 30 is located at the rear side of the moving assembly 40. When the moving assembly 40 moves backward along the first direction, the moving assembly 40 moves in a direction approaching the rotating assembly 30. When the moving assembly 40 moves forward along the first direction, the moving assembly 40 moves in a direction away from the rotating assembly 30.

[0048] Among them, the first cable 51 and the second cable 52 are located at the first end of the rotating assembly 30 in the second direction, and the third cable 53 is located at the second end of the rotating assembly 30 in the second direction. That is to say, both the first cable 51 and the second cable 52 are located at one end of the rotating assembly 30 and the moving assembly 40 in the second direction, and the third cable 53 is located at the other end of the rotating assembly 30 and the moving assembly 40 in the second direction.

[0049] The other end of the first cable 51 is connected to the rear side of the moving assembly 40, the other end of the second cable 52 is connected to the front side of the moving assembly 40, one end of the third cable 53 is connected to the rear side of the moving assembly 40, and the other end of the third cable 53 is connected to the front side of the moving assembly 40.

[0050] When the rotating assembly 30 rotates forward, the rotating assembly 30 winds the first cable 51 and releases the second cable 52, so that the other ends of the first cable 51 and the second cable 52 both move backward in the first direction, and the one end and the other end of the third cable 53 both move backward in the first direction. At this time, the rotating assembly 30 pulls the moving assembly 40 to move in the first direction towards the direction close to the rotating assembly 30 through the other end of the first cable 51 and the one end of the third cable 53. At the same time, the rotating assembly 30 winds the sunshade 10 to store the sunshade 10.

[0051] Among them, the first cable 51 and the third cable 53 simultaneously apply tensile forces to the moving assembly 40 from both ends of the moving assembly 40 in the second direction to smoothly pull the moving assembly 40 to move in the first direction towards the direction close to the rotating assembly 30. In this way, when pulling the moving assembly 40 to move in the first direction, it is convenient to reduce the possibility that the moving assembly 40 is pulled obliquely, and further reduce the possibility that the sunshade 10 generates wrinkles due to uneven stress.

[0052] Specifically, when the rotating assembly 30 rotates, on the one hand, the rotating assembly 30 applies a tensile force to the moving assembly 40 to move towards the direction close to the rotating assembly 30 by winding the sunshade 10, and on the other hand, the rotating assembly 30 applies a tensile force to the moving assembly 40 to move towards the direction close to the rotating assembly 30 through the first cable 51 and the third cable 53.

[0053] When the rotating assembly 30 rotates reversely, the rotating assembly 30 winds the second cable 52 and releases the first cable 51, so that the other ends of the first cable 51 and the second cable 52 both move forward in the first direction, and the one end and the other end of the third cable 53 both move forward in the first direction. At this time, the rotating assembly 30 pulls the moving assembly 40 to move in the first direction away from the rotating assembly 30 through the other end of the second cable 52 and the other end of the third cable 53. At this time, the rotating assembly 30 releases the sunshade 10 wound thereon to deploy the sunshade 10.

[0054] Among them, the second cable 52 and the third cable 53 simultaneously apply tensile forces to the moving component 40 from both ends of the moving component 40 in the second direction, so as to smoothly pull the moving component 40 to move in the first direction away from the rotating component 30. In this way, when pulling the moving component 40 to move in the first direction, it is convenient to reduce the possibility of the moving component 40 being pulled obliquely, and further reduce the possibility of the sunshade 10 generating wrinkles due to uneven force.

[0055] In addition, a first cable 51 and a second cable 52 are arranged at the first end of the rotating component 30, so that one ends of the first cable 51 and the second cable 52 are both fixed to the first end of the rotating component 30, which facilitates the rotating component 30 to wind the first cable 51 and the second cable 52. Specifically, even when the first cable 51 and the second cable 52 are not tightened, it will not affect the winding of the first cable 51 and the second cable 52 by the rotating component 30, avoiding the winding failure of the rotating component 30 with the first cable 51 and the second cable 52, and further being able to avoid the winding failure of the rotating component 30 for the sunshade 10.

[0056] In summary, by rotating the rotating component 30, the automatic winding or automatic unfolding of the sunshade 10 can be realized without the user operating the sunshade 10, which is convenient for improving the user experience.

[0057] In addition, in this embodiment, the retraction and extension of the sunshade 10 are realized by using three cables. This driving scheme for the sunshade 10 is relatively simple, which is convenient for reducing the assembly difficulty of the driving structure, and further reducing the assembly cost.

[0058] Therefore, the driving structure of the sunshade according to the embodiment of the present invention can realize the automatic winding or automatic unfolding of the sunshade 10 by rotating the rotating component 30, can avoid the winding failure of the sunshade, and this driving structure of the sunshade is relatively simple, which is convenient for reducing the assembly difficulty, and further reducing the assembly cost.

[0059] Next, the driving structure of the sunshade according to the specific embodiment of the present invention will be described with reference to the drawings.

[0060] In some specific embodiments of the present invention, as Figures 1-11 shown, the driving structure of the sunshade includes a frame part 20, a rotating component 30, a moving component 40, a first cable 51, a second cable 52, and a third cable 53.

[0061] In some embodiments of the present invention, as Figure 1 , Figure 3 and Figure 5As shown, the rotating assembly 30 includes a rotating shaft 33, a first rotating wheel 31, and a second rotating wheel 32. The rotating shaft 33 extends along the second direction. The first rotating wheel 31 is fixed to the first end of the rotating shaft 33 in the second direction. One end of the first cable 51 and one end of the second cable 52 are both fixed to the first rotating wheel 31. The second rotating wheel 32 is fixed to the second end of the rotating shaft 33 in the second direction. The third cable 53 is wound around the second rotating wheel 32. The driving member 34 is engaged with the first rotating wheel 31 for driving the first rotating wheel 31 to rotate.

[0062] When the driving member 34 drives the first rotating wheel 31 to rotate forward, the first rotating wheel 31 drives the rotating shaft 33 and the second rotating wheel 32 to rotate forward. At this time, one end of the first cable 51 and the third cable 53 pulls the moving assembly 40 to move along the first direction towards the rotating assembly 30. When the driving member 34 drives the first rotating wheel 31 to rotate reversely, the first rotating wheel 31 drives the rotating shaft 33 and the second rotating wheel 32 to rotate reversely. At this time, the other end of the second cable 52 and the third cable 53 pulls the moving assembly 40 to move along the first direction away from the rotating assembly 30.

[0063] Specifically, since the first rotating wheel 31 is the driving wheel, when the first rotating wheel 31 rotates, it needs to apply a force to the moving assembly 40 through the first cable 51 and the second cable 52. When the first cable 51 or the second cable 52 drives the moving assembly 40 from stationary to moving instantaneously, a relatively large force needs to be applied to the moving assembly 40, and thus the first rotating wheel 31 needs to apply sufficient force to the first cable 51 or the second cable 52.

[0064] Among them, in the embodiment where a cable is wound around the first rotating wheel 31, when the driving member 34 drives the first rotating wheel 31 to rotate, sufficient force between the first rotating wheel 31 and the cable is required to drive the cable to move, and it is easy to occur that the cable and the first rotating wheel 31 slip relative to each other, or the force cannot be applied to the cable when the cable is not straightened.

[0065] In some embodiments, the output shaft of the driving member 34 is engaged with the first rotating wheel 31 to directly drive the first rotating wheel 31 to rotate. In other embodiments, the driving member 34 drives the first rotating wheel to rotate through a transmission assembly, and no further limitation is made here.

[0066] In this embodiment, one end of the first cable 51 is fixed to the first rotating wheel 31, and one end of the second cable 52 is fixed to the first rotating wheel 31. In this way, the part of the first cable 51 wound around the first rotating wheel 31 and the part of the second cable 52 wound around the first rotating wheel 31 do not interfere with each other. When the driving member 34 drives the first rotating wheel 31 to rotate forward, the first rotating wheel 31 winds the first cable 51 and releases the second cable 52. When the driving member 34 drives the first rotating wheel 31 to rotate reversely, the first rotating wheel 31 winds the second cable 52 and releases the first cable 51. There will be no situation where the cable slips with the first rotating wheel 31, nor will there be a situation where the cable cannot be straightened and the driving force cannot be applied to the cable.

[0067] The third cable 53 is wound around the second rotating wheel 32. The second rotating wheel 32 serves as a driven wheel. When the driving member 34 drives the first rotating wheel 31 to rotate, the first rotating wheel 31 drives the rotating shaft 33 and the second rotating wheel 32 to rotate. When the first cable 51 or the second cable 52 applies a force to the moving assembly 40, at the moment when the moving assembly 40 moves from a stationary state to a moving state, the force between the moving assembly 40 and the third cable 53 is relatively small. Therefore, it is not necessary to have a large force between the third cable 53 and the second rotating wheel 32. Setting one cable on the second rotating wheel 32 is sufficient to achieve the force of the third cable 53 on the moving assembly 40.

[0068] Compared with setting two cables on the second rotating wheel 32, setting one third cable 53 on the second rotating wheel 32 is convenient for reducing the number of components, thereby reducing the assembly difficulty.

[0069] In some embodiments, as Figure 4 shown, the first rotating wheel 31 has a first insertion protrusion, and the first end of the rotating shaft 33 has a first insertion groove. The axial directions of the first insertion protrusion and the first insertion groove extend along the second direction. The first insertion protrusion and the first insertion groove are inserted and matched along the second direction to realize the fixation of the first rotating wheel 31 and the rotating shaft 33. Further, when the driving member 34 drives the first rotating wheel 31 to rotate, the first rotating wheel 31 can drive the rotating shaft 33 and the second rotating wheel 32 to rotate.

[0070] In some embodiments, as Figure 6 shown, the second rotating wheel 32 has a second insertion protrusion, and the second end of the rotating shaft 33 has a second insertion groove. The axial directions of the second insertion protrusion and the second insertion groove extend along the second direction. The second insertion protrusion and the second insertion groove are inserted and matched along the second direction to realize the fixation of the second rotating wheel 32 and the rotating shaft 33.

[0071] In some examples, the rotating shaft 33 is a hollow shaft, which is convenient for reducing the weight of the rotating shaft 33, and further convenient for reducing the resistance received by the driving member 34 when driving the first rotating wheel 31 to rotate.

[0072] In some alternative embodiments of the present utility model, the first rotating wheel 31 includes a cylinder, and the first cable 51 and the second cable 52 are partially wound around the cylinder of the first rotating wheel 31, so as to facilitate winding the first cable 51 and the second cable 52 around the outer periphery of the first rotating wheel 31, thereby realizing the retraction and release of the first cable 51 and the second cable 52, and reducing the possibility of the first cable 51 and the second cable 52 detaching from the first rotating wheel 31.

[0073] In some embodiments, two first limiting ring portions are provided on the first rotating wheel 31. The two first limiting ring portions are sleeved and fixed at both ends of the first rotating wheel 31 in the second direction and extend beyond the outer periphery of the first rotating wheel 31. The first cable 51 and the second cable 52 are wound between the two first limiting ring portions to limit the positions of the first cable 51 and the second cable 52, and prevent the portions of the first cable 51 and the second cable 52 wound around the first rotating wheel 31 from falling off from both ends of the first rotating wheel 31 in the second direction.

[0074] In some alternative embodiments of the present utility model, the second rotating wheel 32 includes a cylinder, and the third cable 53 is partially wound around the cylinder of the second rotating wheel 32, so as to facilitate winding the third cable 53 around the outer periphery of the second rotating wheel 32 and reduce the possibility of the third cable 53 detaching from the second rotating wheel 32.

[0075] In some embodiments, two second limiting ring portions are provided on the second rotating wheel 32. The two second limiting ring portions are sleeved and fixed at both ends of the second rotating wheel 32 in the second direction and extend beyond the outer periphery of the second rotating wheel 32. The third cable 53 is wound between the two second limiting ring portions to limit the position of the third cable 53 and prevent the portion of the third cable 53 wound around the second rotating wheel 32 from falling off from both ends of the second rotating wheel 32 in the second direction.

[0076] In some alternative embodiments of the present utility model, a spiral first cable groove is provided on the first rotating wheel 31, and the first cable 51 and the second cable 52 are partially wound in the first cable groove to accommodate the first cable 51 and the second cable 52 wound around the first rotating wheel 31, prevent the cables wound around the first rotating wheel 31 from knotting and interfering with each other, and prevent the first cable 51 and the second cable 52 from falling off the second rotating wheel 32.

[0077] In some alternative embodiments of the present utility model, a spiral second cable groove is provided on the second rotating wheel 32, and the third cable 53 is partially wound in the second cable groove to accommodate the third cable 53 wound around the second rotating wheel 32, prevent the cables wound around the second rotating wheel 32 from knotting and interfering with each other, and prevent the third cable 53 from falling off the second rotating wheel 32.

[0078] In some embodiments of the present utility model, such asFigure 1 , Figure 9 As shown in Figure 9 , the drive structure of the sunshade curtain further includes a first guide wheel 61. The first guide wheel 61 is rotatably provided on the frame portion 20. The first guide wheel 61 is separated from the moving assembly 40 in the first direction. A part of the second cable 52 is wound around the first guide wheel 61 to change the extension direction of the second cable 52, so that the other end of the second cable 52 can be connected to the other side of the moving assembly 40 in the first direction. Thus, the second cable 52 can apply a pulling force to the moving assembly 40 to drive the moving assembly 40 to move in the first direction away from the rotating assembly 30.

[0079] In some embodiments, as Figure 9 shown in Figure 9 , the first direction extends in the front-rear direction. The rotating assembly 30 is located at the rear side of the moving assembly 40. The axis of the rotating assembly 30 extends in the second direction. The axis of the first guide wheel 61 extends in the third direction. The third direction, the second direction, and the first direction are perpendicular to each other in pairs.

[0080] A part of the first cable 51 and a part of the second cable 52 are both wound around the outer periphery of the rotating assembly 30. Another part of the first cable 51 extends forward in the front-rear direction. The other end of the first cable 51 is directly connected to the rear side of the moving assembly 40. A section of another part of the second cable 52 extends forward in the front-rear direction and then is wound around the outer periphery of the first guide wheel 61 to change the extension direction of the second cable 52, so that another section of another part of the second cable 52 extends backward in the front-rear direction. Thus, the other end of the second cable 52 is connected to the front side of the moving assembly 40.

[0081] Wherein, when the rotating assembly 30 rotates forward, the rotating assembly 30 winds the first cable 51 to drive the moving assembly 40 to move backward by the first cable 51. When the rotating assembly 30 rotates in the reverse direction, the rotating assembly 30 winds the second cable 52 to drive the moving assembly 40 to move forward by the second cable 52.

[0082] In some embodiments of the present utility model, as Figure 1 shown in Figure 1 , the drive structure of the sunshade curtain further includes a second guide wheel 62. The second guide wheel 62 is rotatably provided on the frame portion 20. A part of the third cable 53 is wound around the second guide wheel 62 to change the extension direction of the third cable 53, so that one end of the third cable 53 is connected to one side of the moving assembly 40 in the first direction, and the other end of the third cable 53 can be connected to the other side of the moving assembly 40 in the first direction. Thus, the third cable 53 can apply a pulling force along the first direction to the moving assembly 40 to drive the moving assembly 40 to move in the first direction towards or away from the rotating assembly 30.

[0083] In some embodiments, as Figure 1As shown, the first direction extends in the front-rear direction. The rotating assembly 30 is located at the rear side of the moving assembly 40. The axis of the rotating assembly 30 extends in the second direction, and the axis of the second guide wheel 62 extends in the third direction. The third direction, the second direction, and the first direction are perpendicular to each other pairwise.

[0084] Here, the third cable 53 is divided into three parts. One end of the third cable 53 is located in the first part 531, the second part 532 is wound around the rotating assembly 30, and the other end of the third cable 53 is located in the third part 533.

[0085] The first part 531 extends forward in the front-rear direction. One end of the third cable 53 is directly connected to the rear side of the moving assembly 40. A section of the third part 533 extends forward in the front-rear direction and then is wound around the outer periphery of the second guide wheel 62 to change the extending direction of the third part 533, so that another section of the third part 533 extends backward in the front-rear direction, and further the other end of the third cable 53 is connected to the front end of the moving assembly 40.

[0086] Among them, when the rotating assembly 30 rotates forward, the rotating assembly 30 winds the first part 531 to drive the moving assembly 40 to move backward by the third cable 53. When the rotating assembly 30 rotates reversely, the rotating assembly 30 winds the third part 533 to drive the moving assembly 40 to move forward by the third cable 53.

[0087] In some embodiments of the present invention, the driving structure of the sunshade curtain further includes a first auxiliary wheel. The first auxiliary wheel is rotatably arranged on the frame part 20. A part of the first cable 51 is wound around the first auxiliary wheel to change the position of the first cable 51 in the third direction. Among them, the third direction is perpendicular to the first direction and the third direction is perpendicular to the second direction, thereby avoiding rubbing between the first cable 51 and the components on both sides of it in the third direction.

[0088] In some embodiments, the first direction extends in the front-rear direction, the third direction extends in the up-down direction, and the axis of the rotating assembly 30 extends in the second direction.

[0089] Among them, a part of the first cable 51 and a part of the second cable 52 are both wound around the outer periphery of the rotating assembly 30. Another part of the first cable 51 extends forward from the lower end of the rotating assembly 30, and another part of the second cable 52 extends forward from the upper end of the rotating assembly 30. The position of the first cable 51 in the third direction is changed by using the first auxiliary wheel, so as to facilitate the other ends of the first cable 51 and the second cable 52 to be on the same horizontal plane, and further facilitate the pulling forces of the first cable 51 on the moving assembly 40 and the second cable 52 on the moving assembly 40 to be on the same straight line.

[0090] In some embodiments of the present invention, such as Figure 3As shown, the drive structure of the sunshade curtain further includes a second auxiliary wheel 72. The second auxiliary wheel 72 is rotatably provided on the frame portion 20. A part of the second cable 52 is wound around the second auxiliary wheel 72 to change the position of the second cable 52 in the third direction, where the third direction is perpendicular to the first direction and the third direction is perpendicular to the second direction, thereby preventing the second cable 52 from rubbing against the components on both sides in its third direction.

[0091] In some embodiments, the first direction extends in the front-rear direction, the third direction extends in the up-down direction, and the axial direction of the rotating assembly 30 extends in the second direction.

[0092] Wherein, a part of the first cable 51 and a part of the second cable 52 are both wound around the outer periphery of the rotating assembly 30. Another part of the first cable 51 extends forward from the lower end of the rotating assembly 30, and another part of the second cable 52 extends forward from the upper end of the rotating assembly 30. The position of the second cable 52 in the third direction is changed by using the second auxiliary wheel 72 so that the other ends of the first cable 51 and the second cable 52 are on the same horizontal plane, and further facilitating the pulling forces of the first cable 51 and the second cable 52 on the moving assembly 40 to be on the same straight line.

[0093] In some embodiments of the present utility model, as Figure 5 shown, the drive structure of the sunshade curtain further includes a third auxiliary wheel 73. The third auxiliary wheel 73 is rotatably provided on the frame portion 20. A part of the third cable 53 is wound around the third auxiliary wheel 73 to change the position of the third cable 53 in the third direction, where the third direction is perpendicular to the first direction and the third direction is perpendicular to the second direction, thereby preventing the third cable 53 from rubbing against the components on both sides in its third direction.

[0094] In some embodiments, the first direction extends in the front-rear direction, the third direction extends in the up-down direction, and the axial direction of the rotating assembly 30 extends in the second direction. Here, the third cable 53 is divided into three parts. One end of the third cable 53 is located in the first part 531, the second part 532 is wound around the rotating assembly 30, and the other end of the third cable 53 is located in the third part 533.

[0095] Wherein, the first part 531 extends forward from the lower end of the rotating assembly 30, and the third part 533 extends forward from the upper end of the rotating assembly 30. The position of the first part 531 or the third part 533 in the third direction is changed by using the second auxiliary wheel 72 so that one end and the other end of the third cable 53 are on the same horizontal plane, and further facilitating the forward pulling force and the backward pulling force of the third cable 53 on the moving assembly 40 to be on the same straight line.

[0096] It should be explained here that it can include two third auxiliary wheels 73 to adjust the positions of the first part 531 and the third part 533 in the third direction respectively, or it can include one third auxiliary wheel 73. There is no excessive limitation here.

[0097] In some embodiments of the present utility model, at least one of the first cable 51, the second cable 52, and the third cable 53 is tensioned by its corresponding tensioning member, and the tensioning member is connected to the moving assembly 40 or the rotating assembly 30 to tension the first cable 51, the second cable 52, and the third cable 53.

[0098] In some embodiments, the drive structure of the sunshade curtain further includes a first tensioning member. The first cable 51 is connected to the moving assembly 40 or the rotating assembly 30 through the first tensioning member to tension the first cable 51, so as to ensure that the sunshade curtain 10 is tightened by the moving assembly 40 and avoid wrinkles on the sunshade curtain 10.

[0099] In some examples, the first tensioning member is a first torsion spring sleeved on the rotating assembly 30. One end of the first torsion spring is connected to one end of the first cable 51 to tension the first cable 51. In other examples, the first tensioning member is a first spring 81. The first spring 81 is arranged on the moving assembly 40, and one end of the first spring 81 is connected to the other end of the first cable 51 to tension the first cable 51.

[0100] In some embodiments, the drive structure of the sunshade curtain further includes a second tensioning member. The second cable 52 is connected to the moving assembly 40 or the rotating assembly 30 through the second tensioning member to tension the second cable 52, ensuring that the sunshade curtain 10 is tightened by the moving assembly 40 and avoiding wrinkles on the sunshade curtain 10.

[0101] In some examples, the second tensioning member is a second torsion spring sleeved on the rotating assembly 30. One end of the second torsion spring is connected to one end of the second cable 52 to tension the second cable 52. In other examples, the second tensioning member is a second spring 82. The second spring 82 is arranged on the moving assembly 40, and one end of the second spring 82 is connected to the other end of the second cable 52 to tension the second cable 52.

[0102] In some embodiments, the drive structure of the sunshade curtain further includes a third tensioning member. The third cable 53 is connected to the moving assembly 40 or the rotating assembly 30 through the third tensioning member to tension the third cable 53, ensuring that the sunshade curtain 10 is tightened by the moving assembly 40 and avoiding wrinkles on the sunshade curtain 10.

[0103] In some examples, the third tensioning member is a third torsion spring sleeved on the rotating assembly 30. One end of the third torsion spring is connected to one end of the third cable 53 to tension the third cable 53. In other examples, the third tensioning member is a third spring 83. The third spring 83 is disposed on the moving assembly 40. One end of the third spring 83 is connected to one end of the third cable 53 to tension the third cable 53.

[0104] In addition, the third cable 53 is tensioned by the third tensioning member so that when the rotating assembly 30 rotates, the third cable 53 can be driven to move, reducing the possibility of the third cable 53 slipping relative to the rotating assembly 30.

[0105] In some embodiments of the present utility model, as Figure 3 , Figure 5 shown, the moving assembly 40 includes a moving shaft 43 and a first sliding member 41. The moving shaft 43 extends along the second direction. The first sliding member 41 is fixed to one end of the moving shaft 43 in the second direction. The first sliding member 41 defines a first chamber and a second chamber arranged along the first direction. The other end of the first cable 51 is provided with a first tensioning member. The first tensioning member is located in the first chamber and is adapted to tension the first cable 51.

[0106] The other end of the second cable 52 is provided with a second tensioning member. The second tensioning member is located in the second chamber and is adapted to tension the second cable 52. That is to say, one end of the first cable 51 is fixed to the rotating assembly 30, and the other end is connected to the moving assembly 40 through the first tensioning member. One end of the second cable 52 is fixed to the rotating assembly 30, and the other end is connected to the moving assembly 40 through the second tensioning member.

[0107] Among them, when the rotating assembly 30 rotates forward, the rotating assembly 30 winds up the first cable 51. At this time, the first cable 51 pulls the moving assembly 40 to move in a direction close to the rotating assembly 30 through the first tensioning member. The moving assembly 40 pulls the other end of the second cable 52 to move through the second tensioning member. At the same time, the rotating assembly 30 pays out the second cable 52. During this process, the second cable 52 is tensioned by the second tensioning member to prevent the second cable 52 from loosening when the moving assembly 40 pays out the second cable 52.

[0108] When the rotating assembly 30 rotates in the reverse direction, the rotating assembly 30 winds up the second cable 52. At this time, the second cable 52 pulls the moving assembly 40 to move in a direction away from the rotating assembly 30 through the second tensioning member. The moving assembly 40 pulls the other end of the first cable 51 to move through the first tensioning member. At the same time, the rotating assembly 30 pays out the first cable 51. During this process, the first cable 51 is tensioned by the first tensioning member to prevent the first cable 51 from loosening when the moving assembly 40 pays out the first cable 51.

[0109] In some embodiments, asFigure 9 , Figure 10 As shown, the first tensioning member is the first spring 81, and the second tensioning member is the second spring 82. The first chamber includes a first side wall, and the second chamber includes a second side wall. The first side wall and the second side wall are opposite to each other in the first direction. One end of the first spring 81 is connected to the other end of the first cable 51, and the other end of the first spring 81 abuts against the first side wall. One end of the second spring 82 is connected to the other end of the second cable 52, and the other end of the second spring 82 abuts against the second side wall.

[0110] When the rotating assembly 30 rotates forward, the rotating assembly 30 winds up the first cable 51. At this time, the first cable 51 compresses the first spring 81, and pulls the moving assembly 40 to move in the direction close to the rotating assembly 30 through the first spring 81. The rotating assembly 30 releases the second cable 52, and the second side wall of the moving assembly 40 compresses the second spring 82, so that the second spring 82 has a force on the other end of the second cable 52 towards the first side wall, thereby tightening the second cable 52 and preventing the second cable 52 from loosening.

[0111] When the rotating assembly 30 rotates reversely, the rotating assembly 30 winds up the second cable 52. At this time, the second cable 52 compresses the second spring 82, and pulls the moving assembly 40 to move in the direction away from the rotating assembly 30 through the second spring 82. The rotating assembly 30 releases the first cable 51, and the first side wall of the moving assembly 40 compresses the first spring 81, so that the first spring 81 has a force on the other end of the first cable 51 towards the second side wall, thereby tightening the first cable 51 and preventing the first cable 51 from loosening.

[0112] In some alternative embodiments of the present utility model, as Figure 5 shown, the moving assembly 40 further includes a second sliding member 42. The second sliding member 42 is fixed to the other end of the moving shaft 43 in the second direction. The second sliding member 42 defines a third chamber and a fourth chamber arranged in the first direction. One end of the third cable 53 is provided with a third tensioning member, and the third tensioning member is located in the third chamber. The other end of the third cable 53 is provided with a fourth tensioning member, and the fourth tensioning member is located in the fourth chamber. The third tensioning member and the fourth tensioning member are adapted to tension the third cable 53.

[0113] Wherein, the third cable 53 is divided into three parts here. One end of the third cable 53 is located in the first part 531, the second part 532 is wound around the rotating assembly 30, and the other end of the third cable 53 is located in the third part 533.

[0114] When the rotating assembly 30 rotates forward, the rotating assembly 30 winds up the first part 531. At this time, the first part 531 pulls the moving assembly 40 to move in the direction close to the rotating assembly 30 through the third tensioning member. The moving assembly 40 pulls the other end of the third cable 53 to move through the fourth tensioning member. At the same time, the rotating assembly 30 pays out the third part 533. During this process, the fourth tensioning member is used to tension the third part 533, thereby tensioning the third cable 53, avoiding the loosening of the third cable 53 when the moving assembly 40 pays out the third part 533, and thus reducing the possibility that the rotating assembly 30 cannot wind the third cable 53 during rotation.

[0115] When the rotating assembly 30 rotates in the reverse direction, the rotating assembly 30 winds up the third part 533. At this time, the third part 533 pulls the moving assembly 40 to move in the direction away from the rotating assembly 30 through the fourth tensioning member. The moving assembly 40 pulls one end of the third cable 53 to move through the third tensioning member. At the same time, the rotating assembly 30 pays out the first part 531. During this process, the third tensioning member is used to tension the first part 531, thereby tensioning the third cable 53, avoiding the loosening of the third cable 53 when the moving assembly 40 pays out the third part 533, and thus reducing the possibility that the rotating assembly 30 cannot wind the third cable 53 during rotation.

[0116] In some embodiments, as Figure 5 , Figure 11 shown, the third tensioning member is the third spring 83, the fourth tensioning member is the fourth spring 84. The third chamber includes a third side wall, the fourth chamber includes a fourth side wall. The third side wall and the fourth side wall are opposite to each other along the first direction. One end of the third spring 83 is connected to one end of the third cable 53, and the other end of the third spring 83 abuts against the third side wall. One end of the fourth spring 84 is connected to the other end of the third cable 53, and the other end of the fourth spring 84 abuts against the fourth side wall.

[0117] When the rotating assembly 30 rotates forward, the rotating assembly 30 winds up the first part 531. At this time, the third cable 53 compresses the third spring 83 and pulls the moving assembly 40 to move in the direction close to the rotating assembly 30 through the third spring 83. The rotating assembly 30 pays out the third part 533. The fourth side wall of the moving assembly 40 compresses the fourth spring 84, so that the fourth spring 84 has a force on the other end of the third cable 53 towards the first side wall, thereby tightening the third cable 53 and avoiding the loosening of the third cable 53.

[0118] When the rotating assembly 30 rotates in the reverse direction, the rotating assembly 30 winds up the third part 533. At this time, the third cable 53 compresses the fourth spring 84, and pulls the moving assembly 40 to move away from the rotating assembly 30 through the fourth spring 84. The rotating assembly 30 releases the first part 531, and the third side wall of the moving assembly 40 compresses the third spring 83, so that the third spring 83 exerts a force on the other end of the third cable 53 towards the second side wall, thereby tightening the third cable 53 and preventing the third cable 53 from loosening.

[0119] In some specific embodiments of the present invention, as Figure 1 shown, a first sliding rail 23 is provided on the frame part 20. The first sliding member 41 is slidably engaged with the first sliding rail 23 to limit the sliding of the first sliding member 41, and further limit the sliding direction of the moving shaft 43, so that the moving shaft 43 can smoothly drive the other end of the sunshade curtain 10 to move in the first direction, thereby facilitating the rotating assembly 30 to wind up the sunshade curtain 10 or release the sunshade curtain 10 wound thereon.

[0120] In some embodiments, the first sliding rail 23 extends in the first direction, so that the first sliding member 41 can smoothly slide in the first direction.

[0121] In some embodiments, as Figure 1 described, the first sliding member 41 is located in the first sliding rail 23 and is slidably engaged with the first sliding rail 23 to prevent the first sliding member 41 from leaking out, thereby preventing external stones or dust from affecting the sliding fit between the first sliding member 41 and the first sliding rail 23.

[0122] In some specific embodiments of the present invention, a second sliding rail 24 is provided on the frame part 20. The second sliding member 42 is slidably engaged with the second sliding rail 24 to limit the sliding of the second sliding member 42, and further limit the sliding direction of the moving shaft 43, so that the moving shaft 43 can smoothly drive the other end of the sunshade curtain 10 to move in the first direction, thereby facilitating the rotating assembly 30 to wind up the sunshade curtain 10 or release the sunshade curtain 10 wound thereon.

[0123] In some embodiments, the second sliding rail 24 extends in the first direction, so that the second sliding member 42 can smoothly slide in the first direction.

[0124] In some embodiments, as Figure 1 described, the second sliding member 42 is located in the second sliding rail 24 and is slidably engaged with the second sliding rail 24 to prevent the second sliding member 42 from leaking out, thereby preventing external stones or dust from affecting the sliding fit between the second sliding member 42 and the second sliding rail 24.

[0125] In some specific embodiments of the present utility model, the frame portion 20 includes two cross beams and two longitudinal beams. The two cross beams extend in the second direction, and the two longitudinal beams extend in the first direction.

The sunshade curtain 10 has two states of being wound around the rotating assembly 30 and at least partially covering the light opening 21, so that the sunshade curtain 10 can open or at least partially close the light opening 21.

[0128] Wherein, when the rotating assembly 30 rotates forward, the rotating assembly 30 winds the sunshade curtain 10, and at the same time, the rotating assembly 30 pulls the moving assembly 40 to move in the direction close to the rotating assembly 30 through the first cable 51 and the third cable 53. The moving assembly 40 can drive one end of the sunshade curtain 10 to move in the direction close to the rotating assembly 30, and further wind the sunshade curtain 10 around the rotating assembly 30, thereby opening the light opening 21 by the sunshade curtain 10.

[0129] When the rotating assembly 30 rotates reversely, the rotating assembly 30 releases the sunshade curtain 10, and at the same time, the rotating assembly 30 pulls the moving assembly 40 to move in the direction away from the rotating assembly 30 through the second cable 52 and the third cable 53. The moving assembly 40 can drive one end of the sunshade curtain 10 to move in the direction away from the rotating assembly 30 to unfold the sunshade curtain 10, so that the sunshade curtain 10 can at least partially cover the light opening 21 to at least partially close the light opening 21.
