Automobile retractable automatic sun-shading device using solar energy

Abstract

The invention discloses an automobile retractable automatic sun-shading device using solar energy. The device is characterized by comprising a photoelectric position sensor, an illumination intensity sensor, an automobile speed sensor, a single chip, a stepping motor, an execution mechanism, a sun-shading device power supply and a solar cell panel, wherein the execution mechanism comprises a sunshade, a sunshade handle, a hollow support axle and a strong magnetic block; the strong magnetic block is fixed at the automobile top through magnetic force; the sunshade handle can freely retract intothe hollow support axle; the solar cell panel is located on the outer surface of the sunshade; the solar cell panel is electrically connected with the sun-shading device power supply; the photoelectric position sensor, the illumination intensity sensor, the automobile speed sensor, the sun-shading device power supply and the stepping motor are all connected with the single chip; and the single chip determines the time of spreading or retracting the sunshade according to the signals of the illumination intensity sensor and the automobile speed sensor, and determines the direction of a surface of the sunshade relative to the sun according to the signal of the photoelectric position sensor.

Description

technical field [0001] The invention provides a sunshade device used in automobiles, which can fully utilize solar energy and can automatically adapt to the direction of light, and belongs to the field of automobile electrical appliances. Background technique [0002] With the development of automobile technology, automobiles are increasingly pursuing automation and intelligence. The old sunshade device is generally a car cover, which needs to be customized according to the size of the car body, and it needs to be put on manually, which is troublesome and labor-saving; Automatic sun-shading device, but also lacks in automatic control and energy consumption. [0003] In addition, the existing sun-shading devices generally only provide corresponding sun-shading functions, and the time when sun-shading is required is generally the time when the sun's rays are relatively strong. A large amount of solar energy is wasted. Contents of the invention [0004] The present inventi...

[0002] With the development of automobile technology, automobiles are increasingly pursuing automation and intelligence. The old sunshade devices are generally car covers, which need to be customized according to the size of the car body, and need to be put on manually, which is troublesome and labor-saving; Automatic shading device, but still lacks in automatic control and energy consumption

[0003] In addition, the existing sun-shading devices generally only provide corresponding sun-shading functions, and the time when sun-shading is required is generally the time when the sun's rays are relatively strong. A lot of solar energy is wasted
