[0036] The sunshade canopy 10 comprises at least a light-reflecting layer arranged on the outer surface and a heat-insulating layer arranged below the light-reflecting layer.

[0037] The tensioning band 14 is a nylon woven band, a sewn cloth band or a magic tape.

[0038] In the embodiment, the sunshade canopy support bodies and the sunshade canopy opening rods are arranged on the two sides, and according to the above concept, the sunshade canopy support bodies and the sunshade canopy opening rods can also be arranged around, and this structure also belongs to the technical scheme of the utility model.

[0039] The utility model has the positive effect that is: through folding the sunshade 10 along the bending line 10c into the front sunshade 10a and the side sunshade 10b towards the two sides of the car, not only can the irradiation of the front sunlight of the windshield glass be isolated, but also the sunlight from the side can be prevented from entering the car, the sun protection effect is improved, and the structure of only relying on the front sunshade is changed; through being provided with the sunshade support opening rod 11 consistent with the bending line 10c on the bending line 10c of the front sunshade 10a and the side sunshade 10b, in addition to being capable of opening the sunshade 10, it is also favorable to the unfolding and retracting of the sunshade 10 by driving the sunshade 10 by the sunshade support opening rod 11; through the coordinated linkage operation of the sunshade support opening rod 11, the efficiency of the unfolding and retracting of the sunshade 10 can be improved; through adopting the hollow triangular prism 12 for the sunshade support, and the hollow triangular prism 12 being composed of three plates coated with the whole flexible fabric outside, supporting the sunshade 10 by the hollow triangular prism 12 can not only improve the stability of the sunshade support, but also can change between the plane and the solid of plate one 12a, plate two 12b and plate three 12c, which is convenient for use and storage, when being stored in the car, plate one 12a, plate two 12b and plate three 12c can be stacked together, and the occupied volume is reduced; through setting the magic tape two 17b and the magic tape one 17a temporarily fixed and pasted with each other at the corresponding positions of the top of the hollow triangular prism 12 and the inner surface of the front sunshade 10a, the top of the hollow triangular prism 12 and the inner surface of the front sunshade 10a can be temporarily fixed by the magic tape 17, and when the sunshade is retracted, under the premise that the fixing belt 14 on the other side of the car is loosened, the magic tape one 17a at the corresponding position of the inner surface of the front sunshade 10a and the magic tape two 17b at the top of the hollow triangular prism can be separated from each other by the force applied to the sunshade closing loop rope 13 on the other side of the car; through setting the sunshade closing loop rope 13 in the channel 15 formed by the upper and lower folding sewn edges of the front sunshade 10, loosening the fixing belt 14a on the arbitrary side and opening the door, the sunshade closing loop rope 13 can be pulled by one hand from the opposite side of the car, the front sunshade 10a can be stacked and retracted to the side of the applied force from the side of the vehicle where the tightening rope 14 is loosened;Then the fixed band 14a on the side of the applied tension is released, the door is opened to release the clamping band 14b, and the sunroof support opening rod is further folded, so that the sunroof 10 can be quickly folded. At the same time, by stacking each group of hollow triangular prism plates 12a, 12b and 12c, the sunshade can be retracted. The use of this quick linkage type folding sunshade can improve the installation efficiency, improve the folding efficiency, shorten the folding time to 5 seconds, and improve the operation convenience. Single-handed and single-time reduction can reduce the occupied volume. Compared with the non-variable elastic support structure of the previous patent CN2023209467979, the folding volume is reduced by 30%. The design can ensure the sunshade effect, improve the uniformity of the distance between the sunshade surface and the glass, and actually measure the cooling speed in the car, which is increased by 40%. The cooling time in the car is shortened, and the cooling energy is saved.
