[0005] Furthermore, during the curtain stretching process, when the diameter of the steel wire rope wound on the retractor is smaller than the diameter of the curtain wound on the rotating shaft, the elastic force of the spring on the curtain decreases; when the diameter of the steel wire rope wound on the retractor is equal to the diameter of the curtain wound on the rotating shaft, the number of torsion turns of the spring remains unchanged, and the output tensioning force on the curtain remains unchanged; when the diameter of the steel wire rope wound on the retractor is larger than the diameter of the curtain wound on the rotating shaft, the elastic force of the spring on the curtain increases.

[0006] Furthermore, the first guide wheel assembly includes a first guide wheel and a third guide wheel fixed on the inner side of the outer frame.

[0007] Furthermore, the steel wire ropes of the two retractors are respectively and sequentially passed around the first guide wheel, the second guide wheel and the third guide wheel on both sides thereof, and are fixedly connected to both ends of the fixing rod.

[0008] Furthermore, the outer frame is triangular, and the lower ends of the outer frames on the left and right sides of the curtain are both fixed with spring components in the opposite direction to the spring components at the upper end.

[0009] Furthermore, the first guide wheel assembly includes a first guide wheel fixed on the inner side of the outer frame.

[0010] Furthermore, the steel wire ropes of the two retractors are respectively passed around the second guide wheel arranged at the upper end of the outer frame, the second guide wheel arranged at the lower end of the outer frame, and the first guide wheel in sequence, and are fixedly connected to both ends of the fixing rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the tension sunshade system provided by the present invention, through the setting of the spring assembly, when winding or unwinding, the spring is in a working state and outputs a certain torque, so that the shaft and the curtain are tightened, which facilitates the winding or unwinding of the curtain smoothly. At the same time, the spring assembly and the first guide wheel assembly can be flexibly set, and can also be flexibly configured for special-shaped canopy curtains.

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Example 1

[0021] See also Figure 1-4The tension sunshade system provided by the present invention comprises an outer frame 1, a motor (existing technology, not shown in the figure) arranged outside the outer frame 1, a rotating shaft 3 arranged in the outer frame 1 and fixedly connected to the output shaft of the motor, a curtain 4 fixed to the rotating shaft 3 at one end and wound on the rotating shaft 3, and a fixing rod 5 fixed to the other end of the curtain 4, and retractors 6 are fixed on the rotating shaft 3 on the left and right sides of the curtain 4, and spring assemblies 7 are fixed on the upper ends of the outer frame 1 on the left and right sides of the curtain 4, and the spring assembly 7 comprises a fixing hook 71, a spring 72 and a second guide wheel 73, one end of the spring 72 is fixedly connected to the fixing hook 71, and the other end of the spring 72 is fixedly connected to the second guide wheel 73, and the first guide wheel assemblies 8 are fixed at both ends of the outer frame 1 on the lower side of the curtain 4, and the steel wire ropes 9 of the two retractors 6 are respectively passed around the first guide wheel assemblies 8 and the second guide wheel 73 on both sides, and are fixedly connected to the two ends of the fixing rod 5.

[0022] During the stretching process of the curtain 4, when the diameter of the steel wire rope 9 wound on the reel 6 is smaller than the diameter of the curtain 4 wound on the rotating shaft 3, the elastic force of the spring 72 on the curtain 4 decreases; when the diameter of the steel wire rope 9 wound on the reel 6 is equal to the diameter of the curtain 4 wound on the rotating shaft 3, the elastic force of the spring 72 remains unchanged, and the output tensioning force on the curtain 4 remains unchanged; when the diameter of the steel wire rope 9 wound on the reel 6 is larger than the diameter of the curtain 4 wound on the rotating shaft 3, the elastic force of the spring 72 on the curtain 4 increases.

[0023] The first guide wheel assembly 8 includes a first guide wheel 81 and a third guide wheel 82 fixed on the inner side of the outer frame 1. The wire ropes 9 of the two reels 6 are respectively and sequentially passed around the first guide wheel 81, the second guide wheel 73 and the third guide wheel 82 on both sides thereof, and are fixedly connected to both ends of the fixed rod 5.

[0024] Example 2

[0025] like Figure 5-7 As shown, the structure of the rotating shaft 3 and the curtain 4 in the second embodiment is the same as that in the first embodiment, but

[0026] The outer frame 1 is triangular in shape, and the lower ends of the outer frame 1 on the left and right sides of the curtain 4 are fixed with spring components 7 in the opposite direction to the spring components 7 on the upper end. The first guide wheel assembly 8 includes a first guide wheel 81 fixed on the inner side of the outer frame 1. The steel wire ropes 9 of the two retractors 6 are respectively and sequentially passed around the second guide wheel 73 set at the upper end of the outer frame 1, the second guide wheel 73 set at the lower end of the outer frame 1, and the first guide wheel 81, and are fixedly connected to both ends of the fixing rod 5.

[0027] When the present invention is working, the motor 2 drives the rotating shaft 3 to retract or extend the curtain 4 and the retractors 6 at both ends, thereby extending or retracting the wire rope 9, thereby realizing the opening or closing of the curtain 4, and the spring 72 is in a working state and outputs a certain elastic force, so that the rotating shaft 3 and the curtain 4 are tightened, so that the curtain 4 is easy to be retracted or extended smoothly.

[0028] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
