通信车轮胎欠压报警器的设计

On Design of Air Pressure Siren on Communications Vehicle

通信车轮胎欠压报警器对提高行车安全和经济性具有十分重要的意义。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,推动扬声器工作来实现汽车轮胎欠压的报警。

The air pressure siren system of the communication vehicle is very important in terms of safety and cost control.The paper proposes exploiting the pressure variation of the auto tire as propulsion,moving the magnet steel through compression and stretch of elastic element,enlarging the signal by spatial magnetic field coupling and propelling speaker to give an alarm of the air pressure siren.
