[0002] As society develops, people's living standards gradually improve, and more and more families own cars. However, with the increasing number of cars, many indoor parking lots and underground parking lots are often full, so people can only park their cars in outdoor parking lots, which causes the cars to be directly exposed to the sun. Especially in summer, after being exposed to the sun, the seats, steering wheels, center consoles and other parts of the car will overheat, making it impossible for people to sit down and drive immediately. Even if the car doors are opened for ventilation or the air conditioner is turned on for cooling, the effect is not ideal, which brings great inconvenience to people driving the car.

[0030] In the description of the present invention, it is necessary to understand that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0031] Working principle:
[0032] When the front windshield reflective heat insulation curtain is used, the winding box 1, the winding box 2 and the connecting box 3 are pasted on the inner side of the front windshield of the car, and the winding motor 4 is started to drive the rotating shaft 5 and the winding drum 6 to rotate. The rotating shaft 5 drives the bevel gear 2 12 to rotate through the bevel gear 1 7, thereby driving the connecting shaft 11 to rotate. The bevel gear 2 12 on the lower half of the connecting shaft 11 drives the bevel gear 3 16 and the winding shaft 14 to rotate, thereby driving the two winding disks 15 to rotate, so that the winding drum 6 and the two winding disks 15 on the winding shaft 14 rotate synchronously, and the winding disk 15 pulls the reflective film 9 downward through the connecting rope 17 to realize the automatic opening of the reflective film 9. The reflective film 9 reflects the sunlight incident on the car, thereby effectively preventing the sunlight from directly shining on the seats, steering wheel and center console in the car, and reducing the degree of overheating.
[0033] When the vehicle needs to be driven, the winding motor 4 is started to rotate in the opposite direction, and the reflective film 9 is automatically wound up by the winding roller. When the reflective film 9 is damaged and needs to be replaced, after the reflective film 9 is fully unfolded, the reflective film 9 is pulled downward, and the magnetic block 8 is taken out from the winding drum 6. The reflective film 9 can be quickly removed from the winding drum 6, and the connecting rope 17 is removed from the fixing ring 10. After replacing the new reflective film 9, the connecting rope 17 is tied to the fixing ring 10, and the magnetic block 8 is adsorbed in the installation groove of the winding drum 6 to complete the installation of the reflective film 9.
