Description

一种用于汽车的防辐射垫及其制造方法
技术领域
本发明涉及汽车用品技术领域，具体涉及一种用于汽车的防辐射垫及其制造方法。
背景技术
电动汽车以车载电源为动力，用电机驱动车轮行驶。电动汽车的大功率大体积电池一般设置在汽车车架中央的电池仓位置，电动汽车的电池组体积较大，长度横跨了整个驾驶舱，一般在车架上从前座位置一致延伸到后座。
在长时间驾驶电动汽车情况下，电驱动系统逆变电路中的IGBT开关管产生电压和电流的突变，可造成电磁辐射。电磁辐射单位是μT微西弗，是磁感应强度的单位。辐射在0.4μT以上属于较强辐射，对人体有一定危害，长期接触易患白血病。如果辐射在0.4μT以下，相对安全。
并且，电动汽车的电驱动系统的功率高，电流瞬间可达上百安倍，比传统燃油高了十倍左右而功率开关管IGBT的频率很高，达十几千赫兹，电压电流突变的时间很短，会产生电磁辐射。电动汽车的动力电池电压高达300-500福特，比传统燃油车的电压平台高了数十倍电磁辐射不可避免。
日常生活中，小于100微西弗的辐射对人体无影响，坐10小时飞机相当于接受30微毫西弗的辐射。因此电动车电磁辐射安全自我防护成为用户常常讨论的问题。
特别对于经常乘车的老人小孩或者孕妇，避免和减少微量辐射是生活所需。
现有的车垫，比如脚垫作为内饰零部件正好位于电动车电池组上方，但仅用于吸尘、去污、隔音等功能。
因此，现有车垫的结构设计亟待改进。
发明内容

表现在产品一种形式上，该防辐射垫为脚垫。
表现在产品的另一种形式上，该防辐射垫为汽车座椅的坐垫或者靠垫或者头枕垫，该防辐射垫的底面上设置弹性带，该防辐射垫通过该弹性带安装在汽车座椅的椅座或者靠背或者头枕上。
第二方面，本发明还涉及一种防辐射垫的制造方法，包括以下步骤：
成型基层以及成型垫面层；
该基层以及垫面层之间通过电镀或者热压或者夹层工艺设置防辐射层。
在电镀实施例中，该防辐射层为电镀金属层，该基层包括第一表面和第二表面，该垫面层包括第三表面以及第四表面，该第二表面或者该第三表面上采用电镀工艺形成该电镀金属层，该电镀金属层由金属银或者金属铅或者金属镍电镀而成。
在热压实施例中，该防辐射层为金属丝网层，该基层包括第一表面和第二表面，该垫面层包括第三表面以及第四表面，该金属丝网层包括经向导电丝以及纬向导电丝，该经向导电丝以及纬向导电丝相互交叉排布形成网状，该金属丝网层高温热压一次成型在该垫面层的第三表面或者该基层的第二表面上。

本发明的用于汽车的防辐射垫及其制造方法，通过在汽车垫的两层状材料之间设置金属防辐射层，该防辐射层可采用电镀工艺镀设在汽车垫材料层一侧，或者采用热压工艺将防辐射层高温热压一体成型或者采用夹层工艺将防辐射层缝制在汽车垫上，该防辐射垫平铺在电动车轿厢的地板或者座椅或者头枕上，充分隔离电动车电池组和电气系统工作时产生的辐射。
