Car movable sunshade

Abstract

The invention discloses a movable sunshade device for a car, which comprises: a cover body, which matches the outer contour of the car when it is fully unfolded, the cover body includes a lower cover surface, an upper cover surface, and the surrounding surfaces of the upper cover surface and the lower cover surface A sealed side cover; a plurality of inflation columns, which are uniformly arranged between the lower cover and the upper cover; the ventilation pipe, which is a serpentine structure, including a plurality of first inflation tubes and a plurality of second inflation tubes. The present invention can pass air into a plurality of inflatable columns through an air pump to completely expand the entire car, and form an air isolation layer with a certain thickness between the car body and the upper surface of the cover, and use the principle of cooling down after the air is compressed The frustum-shaped through-holes are set around the cover body to reduce the temperature of the air insulation layer. The invention has the advantages of convenient use, storage and portability, and good sunshade effect, and can play a role of heat insulation and cooling for cars.

Description

technical field [0001] The invention relates to the technical field of automobile accessories. More specifically, the present invention relates to a movable sunshade device for a car. Background technique [0002] In recent years, the car industry has developed rapidly, and the price of cars has generally declined. Coupled with the improvement of people's material living standards, the supply and demand for cars in the market are also increasing. With the increase in the number of cars, the indoor parking lot has been unable to satisfy the parking of vehicles, so that most vehicles can only be parked outdoors. For a car that is parked outdoors for a long time, it is difficult to find a parking position that can always block the sun. During the day, the sun shines on the car, which makes the temperature inside the car rise sharply. The car occupant cannot enter the car for a short time, and the air conditioner needs to be turned on to the maximum. Cooling the interior of th...

With the increase in the number of cars, the indoor parking lot has been unable to meet the parking requirements of vehicles, so that most vehicles can only be parked outdoors

For a car that is parked outdoors for a long time, it is difficult to find a parking position that can always block the sun. During the day, the sun shines on the car, which makes the temperature inside the car rise sharply. The car occupant cannot enter the car for a short time, and the air conditioner needs to be turned on to the maximum. Cooling the interior of the car increases the frequency and time of use of the car's air conditioner, resulting in a waste of fuel and increased exhaust emissions, which not only consumes time and fuel, but also increases the pollution of the environment; The increase in temperature will lead to an increase in the temperature of rubber products such as seats and steering wheels inside the car, which will produce unpleasant and toxic gases, and accelerate the aging of these products; on the other hand, the increase in temperature in the car will accelerate the aging of electronic equipment in the car. It might even cause a fire
