具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
参见图1，图1为本申请实施例提供的一种无线充电方法的流程图，该方法应用于无线充电设备，如图2和图3所示，所述无线充电设备包括：壳体10和N个天线30，所述壳体10包括用于放置待充电设备20的容置腔，N个所述天线30分别设置于所述容置腔的不同内壁上，N为大于1的整数；如图1所示，上述方法包括以下步骤：
步骤101、从N个所述天线中确定M个目标天线，所述目标天线为与所述待充电设备匹配成功，且对所述待充电设备的充电效率大于预设阈值的天线，M为小于或等于N的正整数。
需要说明的是，当M的取值为1时，则目标天线可以为与待充 电设备匹配成功，且对待充电设备的充电效率最大的天线。这样，可以保证对待充电设备的充电效率最高。
其中，天线的种类在此不做限定，作为一种可选的实施方式，天线可以均为毫米波天线，而毫米波天线发射的毫米波具有带宽范围大，传播衰减小，受自然光和热辐射源影响小等特点，在传输过程中能量损失相对较小。这样，使得毫米波的能量损失较小，从而进一步提升对待充电设备的充电效率。
其中，N个天线分别设置于容置腔的不同内壁上，具体设置方式在此不做限定，容置腔的不同内壁上设置的天线个数可以相同，例如：参见图2，容置腔的每一内壁上可以均设置一个天线30，或者，参见图3，容置腔的每一内壁上可以均设置两个天线30。当然，容置腔的不同内壁上设置的天线个数也可以不相同。
需要说明的是，壳体10的具体形状在此不做限定，壳体10可以为立方体或者三角锥等形状。
作为一种可选的实施方式，所述容置腔的每一内壁上设置有至少一个所述天线。这样，由于容置腔的每一内壁上可以设置有至少一个天线，而天线的数量越多，则可以控制多个天线对待充电设备进行无线充电，从而可以进一步提高对待充电设备的充电效率。
需要说明的是，由于目标天线为与待充电设备匹配成功，且对待充电设备的充电效率大于预设阈值的天线，这样，采用目标天线对待充电设备进行充电时，可以保证每一个目标天线的充电效率均较高。
另外，在容置腔的内壁上还可以设置有风扇，通过设置风扇，可以将天线对待充电设备进行无线充电时产生的热量散去。
另外，容置腔的一内壁上可以开设有可以在打开状态和关闭状态之间切换的腔门，通过该腔门可以将待充电设备放入或者拿出容置腔， 另外，在该腔门打开时，还可以调整待充电设备在容置腔内的位置。需要说明的是，该腔门上可以设置有天线，当然，也可以未设置有天线。具体在此不做限定。
需要说明的是，本申请实施例中的各个步骤均可以由无线充电设备100的控制器执行，参见图4，而上述控制器可以被称作为控制单元16。
而作为一种可选的实施方式，参见图4，所述无线充电设备100还包括：整流滤波电路12、高频转换电路13和功率放大电路14，所述整流滤波电路12用于与电源电连接，且所述整流滤波电路12依次通过所述高频转换电路13、所述功率放大电路14与所述天线电连接。这样，通过上述整流滤波电路12、高频转换电路13和功率放大电路14等部件，使得电流在无线充电设备100内的转换可以更加方便，同时，电流经过功率放大电路14之后，可以增大电流的发射性能，从而使得对待充电设备200的充电效率更高，进而节省了待充电设备200的充电时间。
需要说明的是，上述电源也可以被称作为交流电源11，上述天线也可以被称作为发射天线15。
另外，无线充电设备100还可以包括显示单元17，而控制器可以分别与整流滤波电路12、高频转换电路13、功率放大电路14、天线和显示单元17电连接。
其中，与整流滤波电路12连接的电源可以为交流电源，而整流滤波电路12可以将交流电转换为直流电，从而使得无线充电设备100内的各个部件可以更加方便的识别直流电，而控制器可以向高频转换电路13输出驱动信号，这样，在驱动信号和整流滤波电路12输出的直流电的作用下，高频转换电路13产生高频信号，该高频信号通过 功率放大电路14进一步放大能量，并通过天线将能量发射出去。
另外，控制器还可以控制显示单元17显示各项信息，上述信息包括待充电设备200是否与目标天线配对成功，待充电设备200的充电状态(包括是否处于充电状态中，当前充电量等信息中的至少一种)以及待充电设备200或者无线充电设备100的异常信息等信息中的至少一项。
而待充电设备200可以包括接收天线201、整流转换电路202和负载203，接收天线201可以接收上述天线发射的能量，并通过整流转换电路202将上述能量转换为电能，再流向负载203，而负载203可以被称作为电池，从而达到给待充电设备200的电池进行无线充电的效果。
作为一种可选的实施方式，所述壳体上还设置有位置检测件，所述从N个所述天线中确定M个目标天线，包括：
通过所述位置检测件获取所述待充电设备的位置；
根据所述待充电设备的位置从N个所述天线中确定M个目标天线。
其中，位置检测件也可以被称作为位置传感器，具体类型在此不做限定，例如：可以为红外传感器或者超声波传感器等。
本实施方式中，在确定目标天线时，除了基于与待充电设备匹配成功，以及对待充电设备的充电效率大于预设阈值两项指标外，还增加了通过待充电设备的位置这一项指标来确定目标天线，这样，可以将与待充电设备的距离较近的天线确定为目标天线，从而可以使得目标天线的确定结果更加准确。同时，也可以使得目标天线更能符合待充电设备的充电要求(即距离较近的天线通常更能满足充电要求)。
作为一种可选的实施方式，所述根据所述待充电设备的位置从N 个所述天线中确定M个目标天线，包括：
根据所述待充电设备的位置调整N个所述天线中至少部分天线的位置和朝向中的至少一项；
从调整后的天线中确定M个目标天线。
本实施方式中，可以根据待充电设备在容置腔内的位置，调整至少部分天线的位置和朝向中的至少一项，从调整后的天线中确定目标天线，这样，可以通过调整天线的位置和朝向中的至少一项，从而使得尽可能多的天线能够满足目标天线的条件，使得可以进一步的提高对待充电设备的充电效率。
例如：参见图6和图7，N个天线包括第一天线301、第二天线302和第三天线303，图6和图7中各个天线上的箭头分别表示第一天线301、第二天线302和第三天线303对应的移动和转动方向，其中，图6中A表示第一天线301移动之后的位置，图7中B表示第一天线301转动之后的位置。
另外，参见图5，图5中左侧的天线30的位置未移动，且朝向也未调整，图5中右侧的天线30的朝向调整为朝向智能手表22设置。
需要说明的是，当天线越靠近待充电设备，则该天线对待充电设备的充电效率越高，当天线的辐射方向朝向待充电设备的接收天线时，则对待充电设备的充电效率也就越高。
另外，天线可以粘接在容置腔的内壁上；或者，容置腔的内壁上可以开设有容置槽，而天线可以嵌设于上述容置槽内；或者，天线可以与容置腔的内壁活动连接，使得天线可以相对于容置腔的内壁移动和转动中的至少一项，从而可以调整天线的位置和朝向中的至少一种。
例如：容置腔的内壁上可以开设有滑槽，天线可以通过连接件与滑槽连接，且连接件可以相对滑槽移动，这样，可以随着连接件在滑 槽内的移动，从而可以调节天线在容置腔的内壁的位置。同时，天线可以与连接件转动连接，即天线可以相对于连接件转动，或者，连接件也可以相对滑槽转动，这样，通过天线的转动或者连接件的转动，从而可以调节天线的朝向。
需要说明的是，当判断上述N个天线中不存在目标天线时，作为一种可选的实施方式，所述方法还包括：在不存在所述目标天线的情况下，输出提示信息，所述提示信息用于提示调整所述待充电设备的位置和朝向中的至少一项。
本实施方式中，可以通过输出提示信息的方式，提示用户调整待充电设备在容置腔内的位置和朝向中的至少一项，从而使得调整之后的待充电设备可以具有目标天线，从而控制目标天线对待充电设备进行充电，以提高对待充电设备的充电效率。
作为另一种可选的实施方式，在不存在所述目标天线的情况下，可以控制调节所述待充电设备的位置和朝向中的至少一项，以使得所述待充电设备存在目标天线。
本实施方式中，当不存在目标天线时，无线充电设备可以自动调节待充电设备的位置和朝向中的至少一项，这样，无需用户来调整待充电设备的位置和朝向中的至少一项，提高了对待充电设备调节方式的智能化程度，同时，还可以提高对待充电设备调节效果的准确度。
需要说明的是，为了方便对待充电设备的自动化调节，可以在容置腔内设置位置和朝向可以调节的托盘，而待充电设备可以设置于该托盘上，这样，可以通过调节托盘的位置或朝向，从而对应调节待充电设备的位置或朝向。
步骤102、控制M个所述目标天线对所述待充电设备进行充电。
其中，目标天线可以将能量辐射出去，而待充电设备上可以设置 有接收天线，用于接收上述能量，然后将接收到的能量转换为电能，并将电能输入至电池中，从而完成对电池的充电。
其中，待充电设备的数量在此不做限定，例如：待充电设备的数量可以为一个，也可以为至少两个，参见图2和图3，如待充电设备的数量可以为两个，即待充电设备20可以包括手机21和智能手表22，而对手机21和智能手表22进行无线充电时，可以分别按照上述步骤进行执行，以完成对手机21和智能手表22的无线充电。
本申请实施例中，通过步骤101至102，可以从N个天线中确定M个目标天线，并控制M个目标天线对待充电设备进行充电，而目标天线为与待充电设备匹配成功，且对待充电设备的充电效率大于预设阈值的天线，这样，可以提高对待充电设备的充电效率。
由于无线充电设备对电子设备进行无线充电时，无线充电设备和电子设备两者之间的充电距离越大，则导致充电效率过低，而充电距离越小，则充电效率也就越高；相应的，无线充电设备对电子设备进行无线充电的充电功率越小，则充电效率也就越小，充电功率越大，则充电效率也就越高。这样，通过选择对待充电设备的充电效率大于预设阈值的天线，从而可以使得对待充电设备的充电效率较高。
下面以两个实施例来举例说明，具体参见图8和图9所示的步骤。
图8和图9中的移动终端可以理解为上述实施例中的待充电设备，而无线充电装置则可以理解为上述实施例中的无线充电设备，控制单元可以指的是上述实施例中的控制器，图9中的位置检测单元可以指的是上述实施例中的位置检测件，天线角度可以指的是天线的朝向。
本申请实施例中的无线充电装置可以是装置，也可以是终端中的部件、集成电路、或芯片。该装置可以是移动电子设备，也可以为非移动电子设备。示例性的，移动电子设备可以为手机、平板电脑、笔 记本电脑、掌上电脑、车载电子设备、可穿戴设备、超级移动个人计算机(Ultra-Uobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)等，非移动电子设备可以为服务器、网络附属存储器(Network Attached Storage，NAS)、个人计算机(Personal Computer，PC)、电视机(TeleVision，TV)、柜员机或者自助机等，本申请实施例不作具体限定。
