Abstract：In winter， the front windshield of a car parked outdoors on a snowy day in the north is often completely covered by snow， and the wiper is firmly frozen on the window， which cannot achieve the task of deicing the window. The article put forward a method， which is a wireless power supply method using electromagnetic induction to heat the rubber strip of the car wiper， soften the rubber strip on the wiper， and make it have a certain temperature， so as to facilitate the removal of snow from the front windshield of the car. The frost device can effectively solve the problem that the wiper of a car cannot be used normally after freezing in winter， and it can brighten the window so that the driver can obtain a clear vision. This work does not need to lay complicated circuits and can be applied to most models， saves the time for hot car to melt the ice， and realizes high temperature insulation and interval heating through single-chip programming. It has high safety and brings better deicing experience to car owners， effectively reducing the damage to the car wiper itself caused by the melting of the wiper icing in the winter and the damage to the car turbocharger and engine caused by the long-term hot car， and reducing the fuel consumption and emissions of the car in the winter.

Key words：wireless power supply， wiper， bright window， widely applicable， energy saving and emission reduction

1 背景简述

寒冷的冬季，北方下雪天停在室外的汽车前挡风玻璃常会被积雪完全覆盖。如果此时立即使用雨刮器刮除积雪，可能会由于雨刮器结冰被牢牢地冻在玻璃上而严重损坏雨刮器、刮花车窗玻璃，使驾驶人无法获得清晰的视野。这对于冬季行车安全是非常巨大的隐患，严重时将会危及车主的生命与财产安全，所以人们想出了许多的方式去解决这个问题，比较常见的有如下几种：

（1）雨刮器竖直放置。

（2）挡风玻璃里埋装电热丝。……
