The invention belongs to the field of new energy automobiles, and particularly relates to a self-snow-cleaning skylight of a new energy automobile. The self-snow-cleaning skylight comprises a frame body and a skylight glass plate installed in the frame body; a sliding groove is formed in the side wall of the inner ring of the frame body; an electromagnet is fixedly installed on the top face of thesliding groove; a spiral coil is wound around the electromagnet; a ceramic temperature difference piece and photoresistors are embedded in the skylight glass plate; the positive electrode and the negative electrode of the ceramic temperature difference piece are electrically connected with the two ends of the spiral coil through the photoresistors; a sliding block slides in the sliding groove; apermanent magnet is fixedly connected to the upper end of the sliding block, and the lower end of the sliding block is fixedly connected with the bottom face of the sliding groove through an elastic corrugated pipe. The ceramic temperature difference piece can generate electric energy through the temperature difference inside and outside the automobile to drive snow removing strips to scrape accumulated snow on the surface of the skylight glass plate, a driver does not need to remove snow manually, the good lighting effect in the automobile is guaranteed, other power supplies are not needed for power supply, and the environment-friendly concept of energy conservation and emission reduction of the new energy automobile is reflected.

    本发明属于新能源汽车领域,尤其是涉及一种新能源汽车自清雪天窗,包括框体和安装于框体内的天窗玻璃板,所述框体的内圈侧壁上开设有滑槽,所述滑槽的顶面固定安装有电磁铁,所述电磁铁外绕设有螺旋线圈,所述天窗玻璃板内嵌设有陶瓷温差片和光敏电阻,所述陶瓷温差片的正负极通过光敏电阻与螺旋线圈的两端电连接,所述滑槽内滑动有滑块,所述滑块的上端固定连接有永磁块,所述滑块的下端通过弹性波纹管与滑槽的底面固定连接。本发明可通过车内外温差使陶瓷温差片产生电能,带动清雪条将天窗玻璃板表面的积雪刮除,无需驾驶员手动清雪,保证车内的良好采光效果,且无需其他电源供电,体现了新能源汽车节能减排的环保理念。
