摘要
汽车轮胎欠压报警对提高行车安全性和经济性具有十分重要意义。介绍利用汽车轮胎内气压变化作为动力 ,通过弹性元件压缩、拉伸 ,使磁钢产生位移 ,由空间磁场耦合实现信号放大处理 。
Alarm for auto tyres′ lacking of pressure is very important to raising the driving′s safety and economic performance.This paper introduces the structure and the working principles of a pressure lacking alarm device.This device uses the change of the tyres′ inner pressure as the motive power and makes the magnet steel displaced through the elastic components′ compression and stretching,so the signals are enlarged by magnetic field′s coupling and make the speaker alarm.
