Description

一种电磁感应轮胎轮毂组件、电磁感应轮胎***和电动车 技术领域
本发明涉及电动车领域，具体为一种电磁感应轮胎轮毂组件、电磁感应轮胎***和电动车。
背景技术
车辆在行驶过程中充电一直是人们迫切需要实现的梦想，这样可以解决现有服务器充电桩过少、节假日服务区因充电导致的拥堵的问题；
为了解决该问题，有很多科学家提出了各种各样的解决方案：
https://baijiahao.***.com/s？id＝1736128272834067435&wfr＝spider&for＝pc，主题为《新型充电技术赛道开启！云***匹配，电动汽车行驶过程中完成充电》，提出了两车行驶过程中共享电量的方案。
https://www.pcauto.com.cn/jxwd/2813/28131173.html，主题为《新能源汽车在行驶过程中能充电吗》一文记载：马路上铺设充电磁带，利用电动牙刷的充电原理，为电动车提供电力，电动车一边行驶道路时，一边就能通过地底电缆为车子充满电。但目前没有十分成熟的技术，并且普遍应用需要耗费巨资，还不具备大规模实现的条件。
该方案具有一定的可行性；
如：https://baijiahao.***.com/s？id＝1735527924098101969&wfr＝spider&for＝pc，主题为《边开车边充电，到底能不能实现？》一文中提出了类似于上述方案的详细解决策略。
但是在前人的实验中，发现如下问题：
电磁接收线圈位于汽车底盘，距离过大，电能损耗过大。同时对电磁发射线圈的发射功率提出了更高的要求。
为了解决这个问题，有人提出了采用类似于电车电弓的形式为车辆充电，如ZL201620073165.6公开的电动车免插拔收放式触碰地面导电板充电兼行驶充电装置。
为了解决上述问题，CN201410559376.6公开了提供了一种可充电轮胎以及支持可充电 轮胎给在高速行驶中或停止中的电动汽车自动充电的轮胎型无线充电带***，属新能源汽车领域。所述可充电轮胎中使用了充电接收天线线圈阵列技术和多层接收天线线圈错位阵列组技术，可以有效的接收本发明的轮胎型无线充电带***所发出的无线充电电流，由于可充电轮胎紧贴轮胎型无线充电带，从而有效地提高了无线充电效率并降低了有害的电磁辐射。
该方案创造性的将线圈尽可能的接触地面，以降低无效功耗。
但是该方案存在的问题在于：过多的线圈产生的热量合并轮胎本身运行过程中产生的热量会导致轮胎在行驶过程中持续高热，同时，轮胎的运行会给线圈的稳定、良好的电连接带来不良的结果。
基于以上分析可以得知，现有的充电技术无法同时满足电动车行驶过程中充电、良好的散热、可靠性的需求。
