[0057] In this embodiment, the loop structure 2 may be a flexible closed loop formed by a flexible structure such as a cable.

[0058] In one embodiment, the loop structure 2 is directly connected to the movable side of the sunshade. Since the loop structure 2 is always in a tensioned state, when the loop structure 2 is running and drives the sunshade to unfold or fold, the loop structure 2 can also ensure the tension of the sunshade and prevent the sunshade from wrinkling. On the basis of ensuring the effectiveness of the sunshade switching function, the assembly structure of the retracting device is simplified.

[0059] In another embodiment, the loop structure 2 is connected to the movable side of the sunshade through a pull rod, and the pull rod is fixed to the movable side of the sunshade and connected to the loop structure 2. When the loop structure 2 is running and drives the sunshade to be unfolded or retracted, the pull rod can drive the movable side of the sunshade to move, and provide guidance for the unfolding or retracting of the sunshade, so as to improve the efficiency of unfolding or retracting the sunshade and avoid wrinkling or displacement of the movable side of the sunshade when the sunshade is unfolded or retracted.

[0060] In one embodiment, the driving member 1 includes a motor, which can drive the circuit structure 2 to operate in the forward or reverse direction by rotating the motor forward or reversely, and then the movable rod 4 can drive the sunshade to unfold and retract, so as to realize the opening and closing of the sunshade.

The slider 22 is fixedly connected to the cable 21 and slidably cooperates with the slide rail 5 . The cable 21 can drive the slider 22 to slide along the slide rail 5 .

[0068] In this embodiment, the slider 22 is connected to the movable rod 4 and slidably cooperates with the slide rail 5. The slide rail 5 can provide guidance for the sliding of the slider 22 to provide an accurate path for the movement of the movable rod 4; and the end of the cable 21 is connected to the slider 22.

During the operation of the loop structure 2, the movable rod 4 can be driven to move, and then the movable side of the sunshade is driven to move through the movable rod 4, so as to achieve the purpose of unfolding and folding the sunshade.

[0072] In one embodiment, see Figure 2 The fixing component 3 includes a first fixing component 31 and a second fixing component 32, wherein the first fixing component 31 is located at one end of the movable rod 4 and away from the side of the driving member 1, and the second fixing component 32 is located at the other end of the movable rod 4 and away from the side of the driving member 1;

[0075] In this embodiment, the first slider 221 and the second slider 222 are respectively connected to the two ends of the movable rod 4, and can simultaneously drive the first slider 221 and the second slider 222 to move through the operation of the cable 21, so as to realize the simultaneous movement of the two ends of the movable rod 4, and ensure the balance and stability of the movable rod 4 in driving the sunshade to unfold and fold.

[0076] The cable 21 is sequentially connected to the driving member 1, the first fixed member 31, the first slider 221, the second fixed member 32 and the second slider 222 and then connected back to the driving member 1, thereby forming a circular loop of the cable 21, ensuring that the driving member 1 can respectively drive the sunshade to be unfolded and folded through the movable rod 4 during forward and reverse driving.

[0077] In one embodiment, see Figure 2 The cable 21 includes a first cable 211, a second cable 212 and a third cable 213, and the fixing component 3 includes a plurality of third fixing components 33. The third fixing component 33 is located on a side of the movable rod 4 close to the driving member 1, that is, the third fixing component 33 and the first fixing component 31 and the second fixing component 32 are respectively located on both sides of the movable rod 4;

[0078] The first cable 211 sequentially connects the driving member 1, the first fixing member 31 and the first slider 221, the second cable 212 sequentially connects the first slider 221, at least one third fixing member 33, the second fixing member 32 and the second slider 222, and the third cable 213 sequentially connects the second slider 222, at least one third fixing member 33 and the driving member 1.

[0079] In this embodiment, the first cable 211, the second cable 212 and the third cable 213 are connected end to end to form a closed-loop driving circuit, the driving member 1 is connected to one end of the first cable 211 and the third cable 213 respectively, the other ends of the first cable 211 and the third cable 213 are connected to one end of the first slider 221 and the second slider 222 respectively, and the two ends of the second cable 212 are connected to the other ends of the first slider 221 and the second slider 222 respectively; during the operation of the winding device, the first cable 211, the second cable 212 and the third cable 213 form a driving closed loop, which can effectively ensure that the two ends of the movable rod 4 move in the same direction, thereby improving the synchronization of the movable rod 4 in driving the sunshade to be wound up and stretched.

[0080] In another embodiment, any two of the first cable 211, the second cable 212 and the third cable 213 can be integrally arranged, or the first cable 211, the second cable 212 and the third cable 213 are annular integral structures, and the movable rod 4 can be driven to move by the operation of the cable 21.

[0081] In one embodiment, see Figure 1 The slide rail 5 includes a first slide rail 51 and a second slide rail 52, and the first slide rail 51 and the second slide rail 52 are respectively located on both sides of the movable rod 4 and extend along the retracting direction of the sunshade;

[0082] The first slider 221 is slidably matched with the first slide rail 51 , and the second slider 222 is slidably matched with the second slide rail 52 .

[0083] In this embodiment, when the cable 21 drives the first slide rail 51 and the second slide rail 52 to move, the first slide rail 51 and the second slide rail 52 can slide along the first slide rail 51 and the second slide rail 52 on both sides of the sunshade curtain respectively, ensuring the stability of the movable rod 4 driving the sunshade curtain to extend and retract.

[0084] In one embodiment, see Figure 4 , the driving member 1 comprises a motor 11 and a reel 12, and the reel 12 is connected to the output end of the motor 11;

[0085] The reel 12 is connected to the loop structure 2 and can drive the loop structure 2 to operate. When the loop structure 2 operates, it can be wound around the reel 12 .

[0086] In this embodiment, one end of the first cable 211 and the third cable 213 can be connected to the winding wheel 12. When the winding wheel 12 rotates forward, the first cable 211 can be tightened and wound around the winding wheel 12. At this time, the first cable 211 is the active cable, and the third cable 213 is the driven cable; when the winding wheel 12 is reversed (opposite to the forward rotation direction), the third cable 213 can be tightened and wound around the winding wheel 12. At this time, the third cable 213 is the active cable, and the first cable 211 is the driven cable, so as to ensure the effectiveness of the cable loop operation.

[0088] In this embodiment, when the cable 21 drives the slider 22 to move, part of the cable 21 is an active cable and part of the cable 21 is a driven cable, which will cause part of the cable 21 to be tensioned and part of the cable to be relaxed; when the elastic member 6 is arranged between the cable 21 and the slider 22, the elastic member 6 can absorb the tensioning tolerance when the cable drives the slider 22 to move, maintain the consistency of the tensioning degree of the entire cable 21, and improve the stability of the movable rod 4 in driving the sunshade to move.

[0089] In one embodiment, see Figure 8 The winding wheel 12 is a cone, and the winding radius of the loop structure 2 on the winding wheel 12 gradually increases.
