The invention relates to an automatic sun-shading device for an automobile. The device comprises a sun shield, a sun shield driving mechanism, an electronic compass, a GPS, an illumination sensor anda microprocessor. The input end of the microprocessor is electrically connected with the output end of the electronic compass, the output end of the GPS and the output end of the illumination sensor,and the output end of the microprocessor is electrically connected with the control signal receiving end of the sun shield driving mechanism. The device has the advantages that: the calculation formulas of the solar altitude angle and the solar azimuth angle are edited in the microprocessor, the altitude angle and the azimuth angle of the sun are calculated according to the position information sent by the GPS, the automobile head direction information sent by the electronic compass and the date and the time in the microprocessor; and then the microprocessor controls an electric push rod and aservo motor to work, adjusts the area of the sun shield extending to the lower part of the front windshield and changes the position of the sun shield so that the sun shield is prevented from being opened and adjusted manually, and a driver is prevented from distracting due to the manual adjustment of the sun shield.
本发明涉及一种汽车自动遮阳装置,包括:遮阳板、遮阳板驱动机构、电子罗盘、GPS定位器、光照传感器、微处理器,微处理器的输入端分别与电子罗盘的输出端、GPS定位器的输出端、光照传感器的输出端电性连接,微处理器的输出端与遮阳板驱动机构的控制信号接收端电性连接。有益效果是:将太阳高度角和太阳方位角的计算公式编辑在微处理器中,根据GPS定位器发送的位置信息、电子罗盘发送的汽车车头方向信息、微处理器中的日期和时间计算得到太阳的高度角和方位角,然后微处理器控制电动推杆、伺服电机工作,调节遮阳板伸出到前挡风玻璃下方的面积和改变遮阳板的位置,从而避免人手动打开和调整遮阳板,避免司机手动调整遮阳板而分心。
