Compared with the prior art, the utility model mainly makes the following improvements on the basis of the prior film structure sunshade;

1) Clamping mechanisms are arranged at two ends of the sunshade film, the ends of the sunshade film are clamped by the upper clamping plate and the lower clamping plate, the clamping area of the ends of the sunshade film is increased, the ends of the sunshade film are prevented from being torn, and the use cost is reduced.

2) The tensioning mechanism is arranged between the two ends of the sunshade film, so that the sunshade film is always in a tensioning state, cannot relax, and is not easy to drift along with wind to generate noise.

3) The cantilever is bypassed to the tip of sunshade membrane, forms frictional force under the mechanism effect that rises between sunshade membrane and the cantilever, and when wind blown the sunshade membrane, wind-force acted on the middle part region of sunshade membrane, was weakened by frictional force when transmitting to sunshade membrane both ends, makes sunshade membrane both ends atress reduce, further avoids sunshade membrane tip to tear, reduces use cost.

4) The clamping force of the clamping mechanism on the sunshade film is further increased through the anti-skid rubber cushion, so that the end part of the sunshade film is prevented from being torn, and the use cost is reduced.

5) The length of the tensioning mechanism is adjustable, and under the condition that the distance between the left upright post and the right upright post is unchanged, the length of the tensioning mechanism is changed by rotating the nut, so that the pretightening force of the tension spring is changed. When the solar energy sun-shading film is used in areas with little formation of large wind force, the pretightening force of the tension spring is reduced, the pretightening force of the sun-shading film is reduced, the end part of the sun-shading film is further prevented from being torn, and the use cost is reduced; when the sunshade is used in areas where large wind power can be formed frequently, the pretightening force of the tension spring is increased, the pretightening force of the sunshade film is increased, and noise is further avoided.

In conclusion, the utility model has the advantages of lower use cost and difficult noise generation.
