Abstract

本申请公开了一种无线充电设备及无线充电底座，包括对位机构和至少两个发射线圈；至少两个发射线圈与至少两个电子设备一一对应；各个发射线圈分别为对应的电子设备进行无线充电；各个发射线圈在充电平面形成的各个充电区域之间相互连接或存在重叠；对位机构驱动每个发射线圈与对应的电子设备中的接收线圈对位，发射线圈为对应的电子设备进行无线充电。各个发射线圈形成的充电区域之间连续，各个发射线圈覆盖的充电区域之间没有间隔形成一个连续的充电平面，即多个发射线圈形成一个比较大的充电区域。本申请提供的无线充电设备中的发射线圈可以移动，因此，可以自动实现与电子设备中接收线圈的对位，从而实现电子设备的随放随充，增加无线充电的自由度。
