The invention discloses an automatic folding and unfolding device for a vehicle sun shade. The automatic folding and unfolding device comprises an installation frame installed in front of a windshieldof a cab and a light source sensor installed at one side of the installation frame; a reflection device that reflects light irradiated forward of the vehicle and irradiates the light source sensor; asun-shading device which is mounted in the mounting frame and used for shading the sun, so that light is prevented from directly irradiating the eyes of a driver; and multiple blocking devices whichare evenly distributed and installed at the two sides of the installation frame. The sunlight irradiation angle can be detected by conducting elastic force detection on a measuring spring through a force measuring sensor, the detection precision is high, meanwhile, the sunlight irradiation angle is shielded in a targeted mode, the sun shading effect is guaranteed, and meanwhile the sight of a driver is not shielded; and a filtering device is used for replacing a sun shade to filter light aiming at almost direct sunlight in the morning and at dusk.
本发明公开了一种车用遮阳罩自动收放装置,包括安装框和光源传感器,所述安装框安装于驾驶室挡风玻璃前方,所述光源传感器安装于安装框一侧;反射装置,所述反射装置对车辆前方照射的光线进行反射而照射光源传感器;遮阳装置,所述遮阳装置安装于安装框内部,所述遮阳装置用以遮阳,避免光线直接照射驾驶员眼部;阻挡装置,所述阻挡装置设有多个,且均匀分布安装于安装框两侧,通过测力传感器对测量弹簧进行弹力检测即可对阳光照射角度进行检测,检测精度高,同时对阳光照射角度进行针对性遮挡,保证遮阳效果的同时不对驾驶员视线进行遮挡,针对清晨和傍晚几乎正面直射的阳光,滤光装置代替遮阳罩进行滤光。
