图2为本发明较佳实施例的充电装置中的感应线圈的一种形态的示意图。
图3为本发明较佳实施例的充电装置中的感应线圈的另一种形态的示意图。
图4为本发明较佳实施例的充电装置应用于一便携式电子装置的示意图。
图5为本发明另一个较佳实施例的充电装置应用于一便携式电子装置的示意图。
具体实施方式
请参考图1，本发明的一个较佳实施例提供一种充电装置1，其包括一天线11、一接收器12、以及一电连接于该接收器12的电池13。所述天线11接收来自通信网络的无线电信号，并将该无线电信号产生的电磁波发送给该接收器12，该接收器12与该电池13电性连接，该接收器12在该电磁波作用下产生感应电流，用来对该电池13进行充电。
所述接收器12包括一感应线圈121、一整流单元122和一稳压组件123。该感应线圈121与该整流单元122电性连接，该整流单元122与该稳压组件123电性连接。该感应线圈121以电磁感应的方式将天线11无线传输的电磁波转换成交流电；该整流单元122电性连接该感应线圈121，将该交流电转换为直流电；该稳压组件123电性连接该整流单元122，用于对该直流电进行稳压以输出稳定的直流电压，并将该直流电压传送到电池13，以对电池1进行充电操作。该稳压组件123可以由多个电容并联组成，可改善上述直流电压的波形，产生理想的直流电压，提高充电效率。
该感应线圈121采用导电材料制成，较佳的实施方式是采用相同的材料制造该感应线圈121和该天线11，从而使该感应线圈121和该天线11具有相同的发送和接收频率，进一步使该无线充电装置的电磁感应转换效率提高。
请参考图2，在一个较佳的实施方式中，感应线圈121可卷绕成成各种形状，如图2中密集的方形膜状的感应线圈1210，不同感应线圈1210的圈数会产生不同的感应电流，可依不同规格所需的电压设计不同的感应线圈以调节其电流。
请参考图3，另一个较佳的实施方式中，该感应线圈121和该天线11具有相同材质，如图3中卷绕成密集的同心圆膜状的感应线圈1211，这样可以得到最大的感应电流。
请参考图4，所示为本发明无线充电装置1应用在一便携式电子装置10的一实施方式。该便携式电子装置10包括所述充电装置1，一屏幕14及一电路板15。本实施方式中，该充电装置1的天线11表现为该便携式电子装置的外置天线111，且该外置天线111为和电路板15连接，可依据不同的规格设计，如GSM、GPRS、WCDMA、WIMAX等。该外置天线111所发射的电磁场对准感应线圈1211的中心，以增强充电效果。该感应线圈1211和外置天线111有一间距D，该间距D应不大于该感应线圈1211能够感应到外置天线111电磁波的最远距离。当该外置天线111从通讯网络接收到适当频率的电磁波时，可将该电磁波传送给该感应线圈1211。该感应线圈1211感应到该电磁波，利用电磁感应原理，将该电磁波转换成交流电，卷绕的线圈数量愈多所产生的电流量愈大。该整流单元122将该交流电转换为直流电，该稳压组件123对该直流电进行稳压后输出稳定的直流电压，并将该直流电压传送到电池13，以进行充电操作。当电池13在充电过程中的电压达到和该电容的电压相等时，该电容即无法再对电池13充电，可以防止出现过充的问题。
请参考图5，本发明的充电装置1另一个较佳实施例应用在该便携式电子装置10中。本实施方式中，该充电装置1的天线11表现为该便携式电子装置的内建一隐藏天线112，该感应线圈1211装设于隐藏天线112和屏幕14之间并卷绕成膜状，用于产生屏蔽效应，将绝大部分电磁波与使用者的身体相互隔离。该整流单元122及该稳压组件123。与上述的第一较佳实施例相同。该较佳实施例使用时，其工作方法也与上述的第一较佳实施例相同，但其中该感应线圈1211在使用时能够产生屏蔽效果，防止隐藏天线112在通讯及充电过程中产生的电磁波直接接触人体而产生损害。
可以理解，本发明提供的充电装置1采用无线充电方式，使用更加方便，并能够有效解决现有方式中使用接触式充电技术所产生的接触不良的问题，获得更佳的充电效果。使用中，该充电装置1可以根据不同的负载和电场强度调整感应线圈121的线圈数而获得所需的充电电压，从而可以适用于多种不同类型的电池，解决了不同电池充电器不能通用的问题。另外，该无线充电装置1不仅可以在通讯时对便携式电子装置进行无线充电，同时也可以吸收通讯过程中产生的对人体可能有害的无线电波。
显然，该无线充电装置1应用于便携式电子装置中时，也可以略去其自身包含的电池13，仅保留天线11与接收器12，并将该接收器12与该便携式电子装置的现有电池电性连接，并根据上述方法对该现有的电池进行无线充电。
