As shown in fig. 2 and 3, the present invention provides a sunshade assembly comprising: the two sliding rails 1 are oppositely arranged, and the sliding rails 1 have an extending direction X; the plurality of sunshade curtain components 2 are arranged and connected from front F to back B along the extending direction X, the sunshade curtain components 2 comprise a curtain cloth 21, a scroll structure 22 and two fixing sliding blocks 23, the curtain cloth 21 is wound on the scroll structure 22, and the two fixing sliding blocks 23 are arranged at two ends of the scroll structure 22; the sun-shading curtain component 2 arranged at the forefront is a head sun-shading curtain component 2', the sun-shading curtain component 2 arranged at the rearmost is a tail sun-shading curtain component 2', two fixed sliding blocks 23 of the tail sun-shading curtain component 2' are fixedly arranged on the two sliding rails 1, and the two fixed sliding blocks 23 of the other sun-shading curtain components 2 are in sliding fit with the sliding rails 1 along the extending direction X; the driving mechanism 6 has a movable end 61' movable in the extending direction X, and the movable end 61' is connected to the curtain 21 of the head shade assembly 2 '.

According to the sunshade assembly, the movable end 61' of the driving mechanism 6 is connected with the curtain cloth 21 of the front sunshade assembly 2, the fixed sliding blocks 23 of the rear sunshade assembly 2 are only fixed on the sliding rail 1, and the fixed sliding blocks 23 of the other sunshade assemblies 2 can slide under the driving of the driving mechanism 6, so that the sectional unfolding of the curtain cloth 21 of the sunshade assemblies 2 can be realized when the movable end 61' of the driving mechanism 6 moves forwards along the extending direction X, and the sectional rolling of the curtain cloth 21 of the sunshade assemblies 2 can be realized when the movable end 61' of the driving mechanism 6 moves backwards along the extending direction X and is matched with the rolling force of the rolling shaft structure 22 of the sunshade assemblies 2, so that the sunshade and the use of the sunshade assembly are realized.

The working process of the sunshade curtain assembly comprises the following steps:

the unfolding process comprises the following steps: the movable end 61' of the driving mechanism 6 moves forwards, the curtain cloth 21 of the first sunshade curtain assembly 2' is fully unfolded under the pulling of the movable end 61', and then the curtain cloth 21 of the sunshade curtain assembly 2 behind the fixed sliding block 23 of the first sunshade curtain assembly 2' slides forwards F and is pulled to be fully unfolded until the curtain cloth 21 of the last sunshade curtain assembly 2″ is also fully unfolded under the pulling of the sunshade curtain assembly 2 in front of the last sunshade curtain assembly 2', so that the skylight of the automobile can be fully shielded by the matching of the curtain cloth 21 of a plurality of sunshade curtain assemblies 2;

and (3) a winding process: the movable end 61 'of the driving mechanism 6 moves backward, the curtain 21 of the first sunshade assembly 2' gradually loses the tension of the movable end 61 'and is fully rolled up under the rolling action of the corresponding rolling shaft structure 22, then the fixed sliding block 23 of the first sunshade assembly 2 slides backward B, and the curtain 21 of the second sunshade assembly 2 gradually loses the tension of the first sunshade assembly 2' and is fully rolled up under the rolling action of the rolling shaft structure 22 until the curtain 21 of the last sunshade assembly 2 gradually loses the tension of the front sunshade assembly 2, so that the sunroof of the automobile can be fully exposed.

As shown in fig. 2 and 3, in order to ensure that the shade fabrics 21 in the plurality of shade assemblies 2 can be individually unwound from front to back and individually wound from back to front in the embodiment of the present invention, the orderly unwinding and orderly winding of the shade fabrics in each shade assembly 2 is achieved by controlling the winding force of the reel structure 22 in each shade assembly 2.

The curtain cloth 21 has an unfolding starting state and an unfolding ending state, the rolling force provided by the corresponding rolling shaft structure 22 received by the curtain cloth 21 is the initial rolling force in the initial unfolding state of the curtain cloth 21, and the rolling force provided by the corresponding rolling shaft structure 22 received by the curtain cloth 21 is the ending rolling force in the unfolding ending state of the curtain cloth 21; wherein, in the process of expanding the curtain cloth 21 of two adjacent sunshade curtain assemblies 2, the rolling force of ending in the process of expanding the curtain cloth 21 of the previous sunshade curtain assembly 2 is smaller than the rolling force of initiating in the process of expanding the curtain cloth 21 of the next sunshade curtain assembly 2.

In the process of expanding the curtain cloth 21 in the sunshade curtain assembly 2, the driving mechanism 6 needs to overcome the rolling force of the curtain cloth 21 to draw the curtain cloth 21 to expand, that is, the smaller the rolling force of the curtain cloth 21 is, the easier the curtain cloth 21 is drawn by the driving mechanism 6 to expand, and further the more difficult the curtain cloth is to roll under the rolling force when the pulling force is lost; the larger the rolling force of the curtain cloth 21 is, the harder the curtain cloth is pulled by the driving mechanism 6 to be unfolded, and the easier the curtain cloth is rolled under the rolling force when the pulling force is lost; accordingly, the present invention makes it more difficult to roll the shade fabrics 21 of the shade assemblies 2 arranged more forward by controlling the rolling force provided by the roller structures 22 of the plurality of shade assemblies 2, and makes it more difficult to roll the shade fabrics 21 of the shade assemblies 2 arranged more rearward. Further, by controlling the end rolling force applied to the curtain cloth 21 of the previous sunshade curtain assembly 2 to be smaller than the initial rolling force applied to the curtain cloth 21 of the next sunshade curtain assembly 2, when the curtain cloth 21 of the previous sunshade curtain assembly 2 is unfolded, the curtain cloth 21 of the next sunshade curtain assembly 2 is unfolded, and similarly, when the curtain cloth 21 of the next sunshade curtain assembly 2 is rolled, the rolling force applied to the curtain cloth 21 of the next sunshade curtain assembly 2 is larger, the rolling can be completed first, and the curtain cloth 21 of the previous sunshade curtain assembly 2 is rolled next, so that the curtain cloth 21 in the plurality of sunshade curtain assemblies 2 can be unfolded one by one from front to back and rolled one by one from back to front.

Specifically, four sunshade assemblies 2 are described as an example: when the curtain cloth 21 of the first sunshade curtain assembly 2' is fully unfolded, the end rolling force applied to the curtain cloth is smaller than the initial rolling force applied to the curtain cloth 21 of the second sunshade curtain assembly 2 when the curtain cloth 21 starts to be unfolded under the pulling of the first sunshade curtain assembly 2; likewise, the end rolling force applied to the curtain 21 of the second shade assembly 2 when fully unrolled is less than the initial rolling force applied to the third shade assembly 2 when beginning unrolling under the pull of the second shade assembly 2; likewise, the third shade assembly 2 receives less end roll-up force when fully extended than the initial roll-up force received by the last shade assembly 2 "when beginning to extend under the pull of the third shade assembly 2.

Wherein, between two adjacent sunshade curtain components 2, the front end of the curtain cloth 21 of the rear sunshade curtain component 2 can be directly or indirectly connected with the fixed slide block 23 of the front sunshade curtain component 2, so that the curtain cloth 21 of the front sunshade curtain component 2 can slide by pulling the fixed slide block 23 through the scroll structure 22 after the curtain cloth 21 of the front sunshade curtain component 2 can not be continuously unfolded, and the curtain cloth 21 of the rear sunshade curtain component 2 can be unfolded by pulling the fixed slide block 23 of the front sunshade curtain component 2.
