具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考附图描述根据本发明实施例的无线充电系统1。
如图1-图3所示，根据本发明实施例的无线充电系统1包括电源管理器10(MCU)、发射端线圈20、次级线圈30、多个三级线圈40和接收端线圈50。
其中，电源管理器10、发射端线圈20、次级线圈30和多个三级线圈40置于无线充电装置内，接收端线圈50置于充电设备内。
电源管理器10适于与电源2相连，用于管理充电信息。发射端线圈20与电源管理器10相连。次级线圈30与发射端线圈20耦合以获得能量。次级线圈30分别与多个三级线圈40相连以向三级线圈40供电。接收端线圈50与三级线圈40非接触式耦合，完成无线充电工作。
本领域的技术人员可以理解的是，次级线圈30也可以与接收端线圈50耦合以进行无线充电。
根据本发明实施例的无线充电系统1，通过在发射端线圈20和接收端线圈50之间设置次级线圈30和多个三级线圈40，可以将次级线圈30接收过来的电能作为一个电源以对三级线圈40供电，由此可以利用多个三级线圈40对多个设备同时充电，并且，多个三级线圈40可以按需要分布在不同位置，构成充电网络，当用户将带有接收端线圈50的设备靠近这些三级线圈40时，这些三级线圈40与设备的接收端线圈50进行耦合，从而实现了不同地方，同一时间为各种不同的设备完成充电，这样无需在每个位置都放置充电板，大幅节省了成本和空间。此外，由于三级线圈40单独分离出来放置，三级线圈40与其它部件的位置较远，不仅在充电过程中更加容易散热，而且减少了设备内部热量的传递，从而提高了使用寿命。因此，根据本发明实施例的无线充电系统1能够支持多个设备同时充电，且散热效果好、使用寿命长。
下面参考附图描述根据本发明具体实施例的无线充电系统1。
在本发明的一些具体实施例中，如图1-图3所示，根据本发明实施例的无线充电系统1包括电源管理器10、发射端线圈20、次级线圈30、多个三级线圈40和接收端线圈50。
其中，电源管理器10用于充电时信息的管理，例如充电进度、电量、温度等，同时电源管理器10决定传输频率、优化充电时间和能源消耗等问题以及确定三级线圈40的耦合数量，并在传输效率、磁场强度和共振频率之间确定平衡点。
具体而言，如图3所示，电源管理器10包括集成电路11、温度检测单元12、微处理单元13和显示单元14。
集成电路11具有适于与电源2相连的第一端和与发射端线圈20相连的第二端。温度检测单元12与集成电路11相连。微处理单元13与集成电路11相连。显示单元14分别与微处理单元13和集成电路11相连。
具体而言，电源2通过电源管理器10给发射端线圈20供电。接通电源2后，电源管理器10进行充电前各线圈的检测，例如电流和电压的检测，然后将检测到的数据通过微处理单元13进行处理且显示到显示单元14，当次级线圈30与发射端线圈20耦合，或当三级线圈40与次级线圈30进行二次耦合时，通过对检测到的电流、电压和电量的变化进行分析对比而得出充电状况，同时也可以通过温度检测单元12检测发射端线圈20的温度，并通过显示单元14显示。
在本发明的一些具体示例中，如图1和图3所示，发射端线圈20与次级线圈30非接触式耦合，多个三级线圈40分别通过导线与次级线圈30相连。发射端线圈20利用交变的电场产生变化的磁场，次级线圈30再利用变化的磁场来产生电场，从而产生感应电流为带有接收端线圈50的设备充电。
其中，由于三级线圈40仅需要通过导线连接，三级线圈40可以设置成较薄的结构。
可选地，如图1所示，为了方便发射端线圈20和次级线圈30的固定，发射端线圈20和次级线圈30可以设置在电源管理器10上。
在本发明的一些具体实施例中，次级线圈30与多个三级线圈40之间可以通过导线串联、并联或串并混联连接，多个三级线圈40之间也可以通过导线串联、并联或串并混联连接。
举例而言，图2示出了次级线圈30和多个三级线圈40并联连接的示例，即次级线圈30和多个三级线圈40的内端依次相连且外端依次相连。图2中示出了三个三级线圈40，次级线圈30与三级线圈40的连接方式可以参照将图2中的一个三级线圈40替换为次级线圈30。
当然，次级线圈30和多个三级线圈40也可以串联连接，即次级线圈30和多个三级线圈40的相邻两个中的一个的内端与另一个的外端相连。
本领域的技术人员可以理解地是，本发明对次级线圈30和多个三级线圈40的连接方式不做具体限定，次级线圈30和多个三级线圈40的连接方式可以根据不同设备的不同充电要求，采用不同的连接方式，用来分流或分压，当然也可以在充电设备上设置限流、稳压等电子电路来达到各自的实际应用需求。
在本发明的一些具体示例中，三级线圈40设在散热座(图中未示出)上，该散热座可以由导热、散热性能良好的金属或非金属材料制成，但三级线圈40与所述散热座之间应绝缘良好，这样可以进一步提高三级线圈40的散热效果。
有利地，无线充电系统1还包括磁体(图中未示出)，所述磁体设在三级线圈40的耦合相对面，该磁体可以为磁铁。其中，三级线圈40的耦合相对面是指，三级线圈40与接收端线圈50耦合时，三级线圈40的背离接收端线圈50的面。由此可以利用所述磁体提高 充电效率。
下面参考附图描述根据本发明实施例的无线充电装置。
