[0052] Embodiments of the present application will be described in detail below with reference to the drawings, wherein like or similar elements are denoted by like or similar reference symbols throughout the drawings. The embodiments described below are exemplary only, and are not intended to limit the present application.

[0053] The driving device of the prior art sunshade includes a moving assembly, a rotating assembly and a cable. When the rotating assembly rotates, the moving assembly is pulled to move by the cable. When the moving assembly moves, it drives one end of the sunshade to move, and at the same time the rotating assembly winds or releases the sunshade.

[0054] However, since the sunshade has a certain thickness, when the rotating assembly winds the sunshade, the circumference of the sunshade wound on the rotating assembly becomes longer and longer. However, it cannot be guaranteed that the length of the cable released by the rotating assembly is the same as the circumference of the sunshade wound on the rotating assembly. This results in that the distance moved by the moving assembly is not equal to the length of the sunshade wound by the rotating assembly. This causes the sunshade to be subjected to a tearing force between the rotating assembly and the moving assembly, and the sunshade is easily torn.

[0055] The embodiment of the present application utilizes the winding assembly 20 to wind the sunshade 70. The moving force of the moving assembly 30 and the winding force of the winding assembly 20 on the sunshade 70 are independent of each other. Thus, when the sunshade 70 is stored, the distance moved by the moving assembly 30 and the length of the sunshade wound by the winding assembly 20 are adapted, and a strong tearing force is not formed at the two ends of the sunshade 70 in the first direction, so as to avoid the sunshade 70 from being torn, and thus the stability of the structure is improved.

[0056] The driving structure of the sunshade 70 according to the embodiment of the present application will be described below with reference to the drawings.

[0057] As shown in the drawings, the driving structure of the sunshade 70 according to the embodiment of the present application includes a frame part 10, a winding assembly 20 and a moving assembly 30. Figures 1-7 The winding assembly 20 is arranged in the frame part 10. The winding assembly 20 itself has a winding force suitable for automatically winding the sunshade 70. The moving assembly 30 is suitable for being fixedly connected with one end of the sunshade 70 in the first direction, and is movably arranged in the frame part 10 along the first direction to approach or move away from the winding assembly 20.

[0058]

[0059] ​wherein, when the moving assembly 30 moves along the first direction away from the winding assembly 20, the moving assembly 30 pulls the sunshade curtain 70 to release the sunshade curtain 70 from the winding assembly 20, and at this time the pulling force applied to the sunshade curtain 70 by the moving assembly is greater than the winding force of the sunshade curtain 70 by the winding assembly 20; when the moving assembly 30 moves along the first direction towards the winding assembly 20, the winding assembly 20 is adapted to automatically wind the sunshade curtain 70 under the action of the winding force to roll up the sunshade curtain 70.

[0060] Specifically, when the moving assembly 30 moves along the first direction away from the winding assembly 20, the moving assembly 30 tightens the sunshade curtain 70 and overcomes the winding force of the sunshade curtain 70 by the winding assembly 20 to release the sunshade curtain 70 from the winding assembly 20 to unfold the sunshade curtain 70 and block the sunlight by the sunshade curtain 70; when the moving assembly 30 moves along the first direction towards the winding assembly 20, the moving assembly 30 loosens the sunshade curtain 70, and at this time the winding assembly 20 automatically winds the sunshade curtain 70 to automatically store the sunshade curtain 70.

[0061] wherein, when the moving assembly 30 moves along the first direction, the pulling force of the sunshade curtain 70 by the moving assembly 30 and the winding force of the sunshade curtain 70 by the winding assembly 20 are separated, so that when the sunshade curtain 70 is stored, the distance moved by the moving assembly 30 and the length of the sunshade curtain 70 wound by the winding assembly 20 are adapted, and a strong tearing force is not formed at both ends of the sunshade curtain 70 in the first direction, so as to avoid the sunshade curtain 70 being torn and to facilitate improving the stability of the structure.

[0062] Therefore, according to the driving structure of the sunshade curtain 70 in the embodiments of the present application, the pulling force of the sunshade curtain 70 by the moving assembly 30 and the winding force of the sunshade curtain 70 by the winding assembly 20 are separated, the pulling force of the sunshade curtain 70 by the moving assembly 30 is greater than the winding force of the sunshade curtain 70 by the winding assembly 20 when the sunshade curtain 70 is released, and the winding force of the sunshade curtain 70 by the winding assembly 20 is automatically implemented when the sunshade curtain 70 is stored, so that the distance moved by the moving assembly 30 and the length of the sunshade curtain 70 wound by the winding assembly 20 are adapted when the sunshade curtain 70 is stored, and a strong tearing force is not formed at both ends of the sunshade curtain 70 in the first direction, so as to avoid the sunshade curtain 70 being torn and to facilitate improving the stability of the structure.

[0063] The driving structure of the sunshade curtain 70 according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0064] In some embodiments of the present application, as shown in Figures 1-7 the driving structure of the sunshade curtain 70 comprises a frame body 10, a winding assembly 20 and a moving assembly 30.

[0065] In some embodiments of the present application, as shown in Figure 8 , Figure 9As shown, the winding assembly 20 comprises a winding shaft 21 rotatably arranged relative to the frame 10 for winding the sunshade curtain 70, and the winding shaft 21 extends along a second direction different from the first direction.

[0066] When the moving assembly 30 moves away from the winding assembly 20 along the first direction, the winding assembly 20 can generate a winding force to resist the rotation of the winding shaft 21 when the winding shaft 21 is subjected to a force, so as to store energy for the winding shaft 21, and when the force acting on the winding shaft 21 disappears, the winding assembly 20 can exert the winding force of the sunshade curtain 70 on the winding shaft 21 to automatically wind the sunshade curtain 70 on the winding shaft 21.

[0067] Specifically, when the moving assembly 30 moves away from the winding assembly 20 along the first direction, the moving assembly 30 tightens the sunshade curtain 70, at this time the winding shaft 21 releases the sunshade curtain 70, and the winding assembly 20 is energized due to the force. When the moving assembly 30 moves towards the winding assembly 20 along the first direction, the moving assembly 30 loosens the sunshade curtain 70, at this time the winding assembly 20 releases the winding force and drives the winding shaft 21 to rotate to automatically wind the sunshade curtain 70, thereby automatically storing the sunshade curtain 70.

[0068] In some optional embodiments of the present application, as shown in Figure 8 , Figure 9 As shown, the winding assembly 20 further comprises an elastic winding part 22, a part of the elastic winding part 22 is directly or indirectly fixed to the frame 10, the elastic winding part 22 is also directly or indirectly connected to the winding shaft 21, and the elastic winding part 22 is adapted to exert a winding force on the winding shaft 21 to automatically wind the sunshade curtain 70 on the winding shaft 21, so that when the moving assembly 30 moves towards the winding assembly 20 along the first direction, the sunshade curtain 70 is loosened, the winding shaft 21 can automatically wind the sunshade curtain 70, thereby storing part of the sunshade curtain 70 on the winding shaft 21.

[0069] Specifically, when the moving assembly 30 moves away from the winding assembly 20 along the first direction, the moving assembly 30 tightens the sunshade curtain 70, at this time the winding shaft 21 releases the sunshade curtain 70, and the elastic winding part 22 is energized due to the force. When the moving assembly 30 moves towards the winding assembly 20 along the first direction, the moving assembly 30 loosens the sunshade curtain 70, at this time the elastic winding part 22 releases the winding force to drive the winding shaft 21 to rotate, thereby enabling the winding shaft 21 to automatically wind the sunshade curtain 70.

[0070] Here, it needs to be explained that the part of the elastic winding part 22 is directly or indirectly fixed to the frame 10, which can be that the part of the elastic winding part 22 is directly fixed to the frame 10, or that the part of the elastic winding part 22 is fixed to the frame 10 through other structures.

[0071] Similarly, the elastic winding part 22 is directly or indirectly connected to the winding shaft 21, which can be that the elastic winding part 22 is directly connected to the winding shaft 21, or the elastic winding part 22 is connected to the winding shaft 21 through other structures, so as to drive the winding shaft 21 to rotate.

[0072] In some optional embodiments of the present application, as shown in Figure 3 , Figure 4 , the winding assembly 20 comprises a rotating part 23 rotatably arranged on the frame part 10, and the elastic winding part 22 is connected to the winding shaft 21 through the rotating part 23. The elastic winding part 22 is adapted to apply a winding force to the winding shaft 21 through the rotating part 23, so that when the moving assembly 30 moves in the first direction towards the direction close to the winding assembly 20, the sunshade curtain 70 is loosened, the winding shaft 21 can automatically wind the sunshade curtain 70 due to the rotating force of the elastic winding part 22, and then part of the sunshade curtain 70 is stored on the winding shaft 21.

[0073] In some specific embodiments of the present application, as shown in Figure 3 , Figure 5 and Figure 9 , the winding assembly 20 further comprises a fixed part 24 which is arranged in a spaced manner with the rotating part 23, and the fixed part 24 is fixed to the frame part 10. One end of the elastic winding part 22 is fixed to the fixed part 24, so that the one end of the elastic winding part 22 is fixed, and the other end of the elastic winding part 22 can apply a rotating force to the rotating part 23, and then apply a rotating force to the winding shaft 21. When the moving assembly 30 moves in the first direction towards the direction close to the winding assembly 20, the sunshade curtain 70 is loosened, the winding shaft 21 can automatically wind the sunshade curtain 70, and then part of the sunshade curtain 70 is stored on the winding shaft 21.

[0074] In some embodiments, as shown in Figure 4 , Figure 5 , the fixed part 24 is provided with a first threaded groove 241, and the rotating part 23 is provided with a second threaded groove 232. One end of the elastic winding part 22 is wound around the first threaded groove 241, and the other end of the elastic winding part 22 is wound around the second threaded groove 232, so as to fix one end of the elastic winding part 22 to the fixed part 24, and arrange the other end of the elastic winding part 22 on the rotating part 23. The elastic winding part 22 can apply a rotating force to the rotating part 23, so that the rotating part 23 rotates, and the rotating part 23 drives the winding shaft 21 to rotate, so that the winding shaft 21 can automatically wind the sunshade curtain 70.

[0075] In some specific embodiments of the present application, one end of the winding shaft 21 in the second direction has a limiting part, and the rotating part 23 is provided with a counterpart part matched with the limiting part, so that when the rotating part 23 rotates, the winding shaft 21 is driven to rotate, and the winding shaft 21 can automatically wind the sunshade curtain 70.

[0076] In some embodiments, the limiting part includes one of the insertion slot and the insertion protrusion 231, the counterpart part includes the other one of the insertion slot and the insertion protrusion 231, the insertion slot and the insertion protrusion 231 are inserted and matched to connect the reel 21 and the rotating part 23 together, so that when the rotating part 23 rotates, the rotating part 23 can drive the reel 21 to rotate, and the reel 21 can automatically wind the sunshade curtain 70.

[0077] In some embodiments of the utility model, the reel 21 is a hollow shaft, the reel 21 is at least partially sleeved on the elastic winding part 22, at least partially sleeved on the fixed part 24, and at least partially sleeved on the rotating part 23, which on the one hand facilitates the connection of the reel 21 and the rotating part 23, and on the other hand facilitates the space saving by sleeving the reel 21 with the elastic winding part 22, the fixed part 24 and the rotating part 23.

[0078] In some embodiments, the reel 21 extends along the second direction, a part of the elastic winding part 22 at one end of the second direction is located in the first threaded groove 241 of the fixed part 24, a part of the elastic winding part 22 at the other end of the second direction is located in the second threaded groove 232 of the rotating part 23, and the elastic winding part 22 has a rotating force on the rotating part 23, and the rotating part 23 is connected with the reel 21 at the other end of the second direction.

[0079] Specifically, when the moving assembly 30 moves along the first direction towards the direction close to the winding assembly 20, the rotating part 23 drives the reel 21 to rotate in the counterclockwise direction due to the rotating force of the elastic winding part 22 to accommodate the sunshade curtain 70, and at this time the elastic winding part 22 releases the winding force.

[0080] When the moving assembly 30 moves along the first direction away from the winding assembly 20, the moving assembly 30 pulls the sunshade curtain 70, and at the same time drives the reel 21 to rotate in the clockwise direction, so that the reel 21 releases the sunshade curtain 70, and at the same time the reel 21 drives the rotating part 23 to rotate in the clockwise direction, and the rotating part 23 applies a winding force to the elastic winding part 22, so that the elastic winding part 22 has a winding force to drive the rotating part 23 to rotate in the counterclockwise direction at this time, and in turn the reel 21 can automatically wind the sunshade curtain 70.

[0081] In some embodiments of the utility model, as shown in Figures 3-5 The driving structure of the sunshade curtain 70 further includes a driving device 40 and a transmission assembly, the transmission assembly is connected with the driving device 40, and the driving device 40 drives the moving assembly 30 to move along the first direction through the transmission assembly.

[0082] The driving of the moving assembly 30 in the first direction towards the direction away from the winding assembly 20 tightens the sunshade curtain 70, and the winding assembly 20 can release the sunshade curtain 70.

[0083] In some optional embodiments of the present application, as shown in Figure 4 、 Figure 5 The transmission assembly comprises a rotating member, a first conveying belt 51 and a second conveying belt 52. The rotating member extends in a second direction. The driving device 40 cooperates with the rotating member to drive the rotating member to rotate. A part of the first conveying belt 51 is arranged around one end of the rotating member in the second direction. The moving assembly 30 is fixedly connected with the first conveying belt 51. A part of the second conveying belt 52 is arranged around the other end of the rotating member in the second direction. The moving assembly 30 is fixedly connected with the second conveying belt 52. The second direction is different from the first direction.

[0084] Specifically, when the driving assembly drives the rotating member to rotate, the rotating member drives at least a part of the first conveying belt 51 and the second conveying belt 52 to move in the first direction, and then drives the moving assembly 30 to move through the first conveying belt 51 and the second conveying belt 52, so that the moving assembly 30 can move in the first direction.
