下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的无线充电方法、装置和无线充电设备进行详细地说明。
请参考图1，为本申请实施例提供的一种无线充电方法的流程示意图。如图1所示，本申请实施例中的无线充电方法应用于无线充电设备，该无线充电设备包括终端以及与所述终端可拆卸连接的天线模组，所述天线模组与所述终端的外形相适配，所述方法包括以下步骤：
步骤11：在检测到所述终端与有线充电器连接的情况下，对与所述终端已连接的至少一个待充电设备进行定位；
本申请实施例中，所述终端与所述天线模组之间的连接可以包括电连接，以实现信号传输，还可以包括结构上的连接，例如两者呈可拆卸式连接，以方便天线模组拆离或安装。其中，所述终端还连接有至少一个待充电设备，所述终端与所述至少一个待充电设备之间可以以蓝牙匹配的方式构建连接关系，也可以通过路由器等建立网络连接。在检测到所述终端与有线充电器连接的情况下，所述终端对已连接的至少一个待充电设备进行定位，以根据定位的结果，控制所述天线模组进行波束赋形等处理，以确定天线的最大增益方向，从而提高无线充电的效率。
步骤12：根据所述待充电设备的位置，控制所述天线模组向所述待充电设备进行无线充电。
在通过所述终端对至少一个待充电设备进行定位之后，即可根据待充电设备的位置，通过终端控制所述天线模组向待充电设备进行无线充电，例如通过波束赋形等技术手段向所述待充电设备所在的位置定向发射电磁波，以实现高效的无线充电。
由此，本申请实施例中，天线模组不需要固定搭配现有技术中普遍采用的控制模组，而是直接与终端进行连接，利用终端的运算处理功能实现对天线模组的逻辑控制，从而使得天线模组可以搭配任意终端，将有线电源转化为无线电磁波对待充电设备进行无线充电，提高了天线模组的匹配度，拓展了天线模组的控制逻辑；并且，由于终端已预先与待充电设备建立了连接，因此可以通过终端快速定位待充电设备并完成充电前的协商，从而提高了无线充电的效率。
在本申请的一些实施例中，在对与所述终端已连接的至少一个待充电设备进行定位之前，所述终端可以接收至少一个待充电设备发送的充电请求，从而终端响应于所述充电请求，对该待充电设备进行定位，继而控制天线模组对该待充电设备进行无线充电，此时，充电请求由待充电设备主动发起。 当然，在本申请的另一些实施例中，在对与所述终端已连接的至少一个待充电设备进行定位之前，所述终端可以向至少一个已连接的待充电设备发送充电请求，从而待充电设备响应于所述充电请求，向所述终端发送确认充电的回复，之后，终端再响应于该确认充电的回复，对该待充电设备进行定位，继而控制天线模组对该待充电设备进行无线充电，此时，充电请求由终端主动发起。
在本申请的一些实施例中，通常所述终端采用电池供电，其自身所携带的电量有限，因此，为了保证终端的正常工作以及天线模组的发射功率，所述终端可以与现有的充电器连接，连接方式包括但不限于通用串行总线(Universal Serial Bus，USB)、Tpye-C等，从而，本申请中的无线充电设备可以直接抓取有线电源，并通过终端和天线模组转化为无线电磁波为待充电设备，在实现为终端进行有线充电的同时，也可以为待充电设备进行无线充电，从而实现了与现有终端、充电器的良好匹配，省去了额外的控制模块以及供电模块。
本申请的另一些实施例中，所述对与所述终端已连接的至少一个待充电设备进行定位，包括：
控制所述终端向所述待充电设备发送第一控制指令，所述第一控制指令用于控制所述待充电设备开启红外接收功能；
控制所述终端向所述待充电设备发送红外信号；
接收所述待充电设备发送的解码信息，所述解码信息为所述待充电设备对接收到的所述红外信号进行解码得到。
也就是说，本申请实施例中对待充电设备进行定位时可以采用红外遥控定位，以实现待充电设备的准确定位。具体来说，由于终端与待充电设备已建立连接，因此，终端可以通过蓝牙等向待充电设备发送第一控制指令，以控制待充电设备开启红外接收功能，若待充电设备处于睡眠状态，所述第一控制指令还可以唤醒所述待充电设备、唤醒后让待充电设备开启红外接收功能，通过在定位时才控制待充电设备开启红外接收功能，可以降低待充电设 备的功耗；之后，再通过所述终端向所述待充电设备发送红外信号，所述红外信号可以由终端调用已经蓝牙匹配的待充电设备的产品编码对信号进行编码调制后得到；待充电设备接收到所述红外信号之后，将对接收到的红外信号进行解码，得到解码信息，并发送回所述终端；所述终端接收所述待充电设备发送的解码信息，之后便可依据所述解码信息完成对待充电设备的定位，待充电设备的准确定位有利于提高后续无线充电的效率。
可选的，在充电过程中，还可以周期性地检测所述终端的姿态，当所述终端的姿态发生大幅度改变时，可以重复上述定位过程，以更新所述待充电设备的定位，保证天线模组可以最快跟进天线最大增益方向。
本申请的一些实施例中，所述天线模组包括天线片，所述根据所述待充电设备的位置，控制所述天线模组向所述待充电设备进行无线充电，包括：
根据所述待充电设备的位置，控制所述天线片向位于所述天线片的预设方位角范围内的所述待充电设备进行充电。
具体的，所述无线充电设备的天线模组包括天线片，所述天线片可以呈矩形等平面形状，在控制天线模组向所述待充电设备进行无线充电时，需要根据待充电设备的位置，选择方向合适的天线片对相应的待充电设备进行充电，以保证无线充电的效率。可选的，所述天线片所在平面垂直于水平面，则该天线片可以为处于其预设方向角范围内的待充电设备进行充电，例如，所述预设方位角范围可以是所述天线片正对的±60°的范围内，即在水平方向上为±60°、在竖直方向上为±60°所限定出的范围内。可以知道，在天线片的数量为一个时，该一个天线片为位于其预设方位角范围内的所述待充电设备进行充电；在天线片的数量为多个时，各天线片可以单独为位于各自预设方位角范围内的所述待充电设备进行充电，也可以至少两个天线片组成一个天线为位于其预设方位角范围内的所述待充电设备进行充电。
在本申请的另一些实施例中，所述天线片的数量为多个，所述控制所述天线片向位于所述天线片的预设方位角范围内的所述待充电设备进行充电，包括：
将至少两个所述天线片在同一平面展开，控制所述至少两个天线片同时向预设方位角范围内的所述待充电设备进行充电。
此情况下，所述天线模组包括多个天线片，即两个或两个以上，此时，在控制天线片向位于预设方位角范围内的所述待充电设备进行充电时，可以将至少两个天线片在同一平面内展开，使在同一平面内展开的至少两个天线片合为一个，从而控制所述至少两个天线片同时向预设方位角范围内的所述待充电设备进行充电。由此，通过多个天线片合为一个共同对一个待充电设备进行充电，可以有效提高无线充电的效率。
在本申请的再一些实施例中，所述天线片设置于所述终端的背面，并与所述终端可拆卸地连接，所述天线片包括沿所述终端的长度方向依次设置的第一天线块、第二天线块和第三天线块，所述控制所述天线片向位于所述天线片的预设方位角范围内的所述待充电设备进行充电，包括：
利用SAR传感器检测人体与所述终端的距离是否小于预设范围；
在人体与所述终端的距离大于预设范围的情况下，控制所述第一天线块、所述第二天线块和所述第三天线块同时向位于所述天线片的预设方位角范围内的所述待充电设备进行充电；
在人体与所述终端的距离小于预设范围的情况下，检测所述第一天线块、所述第二天线块、所述第三天线块的电平以及所述终端的姿态，并根据所述第一天线块、所述第二天线块和所述第三天线块的电平以及所述终端的姿态，控制所述第一天线块、所述第二天线块和所述第三天线块中的一者或两者向位于所述天线片的预设方位角范围内的所述待充电设备进行充电。
示例性的，在一些可选的实施例中，所述终端为手机，可以将所述天线模组制作成与手机壳相同或类似的形状，例如在天线片四周增加硅胶套制成手机壳，或者制作成与手机的背面形状相适配的形状，以方便将天线模组可拆卸地设置在终端的背面，方便携带，并且基本不影响终端的正常使用，此时，可以多个天线片折叠后作为整体设置在终端的背面，也可以仅将一个天线片设置在终端的背面。所述天线片包括沿所述终端的长度方向依次设置的 第一天线块、第二天线块和第三天线块，例如，终端通常呈矩形，因此其长度方向即矩形的长边的延伸方向，第一天线块、第二天线块和第三天线块均可以独立工作。
在控制所述天线片向位于所述天线片的预设方位角范围内的所述待充电设备进行充电时，需要考虑用户此时是否正在使用所述终端，若用户此时正在使用终端，则可能对天线模组产生遮挡，影响发射效率，因此，可选的，可以利用电磁波吸收比值(Specific Absorption Rate，SAR)传感器来检测人体与所述终端的距离，若检测到人体与终端的距离大于预设范围，则认为用户并未靠近、使用所述终端，此时，所述天线片的第一天线块、第二天线块和第三天线块可以同时工作，向位于所述天线片的预设方位角范围内的所述待充电设备进行充电；若检测到人体与终端的距离小于或等于预设范围，则认为用户已经靠近、手持使用所述终端，此时，可以进一步检测所述第一天线块、所述第二天线块、所述第三天线块的电平以及所述终端的姿态，结合电平的高低以及终端的姿态，可以判断出所述第一天线块、所述第二天线块、所述第三天线块中哪一部分被遮挡，从而控制未被遮挡的部分向位于所述天线片的预设方位角范围内的所述待充电设备进行充电。
在本申请的一些实施例中，所述根据所述第一天线块、所述第二天线块和所述第三天线块的电平以及所述终端的姿态，控制所述第一天线块、所述第二天线块和所述第三天线块中的一者或两者向位于所述天线片的预设方位角范围内的所述待充电设备进行充电，包括：
在所述终端的姿态处于横屏状态、且所述第一天线块的电平和所述第三天线块的电平相差小于第一电平阈值的情况下，控制所述第二天线块向位于所述天线片的预设方位角范围内的所述待充电设备进行充电；
在所述终端的姿态未处于横屏状态、且所述第一天线块的电平和所述第三天线块的电平相差大于第一电平阈值的情况下，控制所述第一天线块、所述第三天线块中电平较高的一者和所述第二天线块同时向位于所述天线片的预设方位角范围内的所述待充电设备进行充电。
具体的，在终端处于横屏姿态时，若所述第一天线块的电平和所述第三天线块的电平相差小于第一电平阈值，即两者电平相差不大，通常所述第一天线块的电平、所述第三天线块的电平也比第二天线块的电平小一定的值，则意味着此时所述终端被用户横屏持握，终端的两端被手持遮挡，此时，则可以控制未被遮挡的第二天线块向位于所述天线片的预设方位角范围内的所述待充电设备进行充电；在终端未处于横屏姿态时，若所述第一天线块的电平和所述第三天线块的电平相差大于第一电平阈值，即两者电平相差较大，通常所述第一天线块、所述第三天线块中的电平较小者也比第二天线块的电平小一定的值，则意味着此时所述终端被用户竖屏持握，终端的一端被手持遮挡，此时，则可以控制所述第一天线块、所述第三天线块中电平较高的一者和所述第二天线块同时向位于所述天线片的预设方位角范围内的所述待充电设备进行充电，其中，所述第一天线块、所述第三天线块中电平较高的一者即未被遮挡。
可选的，为获取所述第一天线块、所述第二天线块、所述第三天线块的电平，可以控制终端利用所述第一天线块、所述第二天线块、所述第三天线块与待充电设备进行信号收发，从而使所述第一天线块、所述第二天线块、所述第三天线块产生电平。
由此，本申请实施例通过判断所述第一天线块、所述第二天线块、所述第三天线块中哪一部分被遮挡，从而控制未被遮挡的部分向位于所述天线片的预设方位角范围内的所述待充电设备进行充电，可以提高充电效率，减少充电损耗，并且不影响终端的正常使用。
请参考图2，为本申请实施例提供的一种充电控制逻辑的示意图。如图2所示，终端通过USB线与外部电源连接实现有线充电，天线模组制作成隔空的充电壳与终端可拆卸地连接，两者具有相匹配的物理接口，所述天线模组可以有四面天线，即四个天线片，然后，终端向待充电设备发起充电请求，待充电设备响应后，终端对待充电设备进行定位，定位成功后，控制天线模组开启馈电网络辐射电磁波，以对待充电设备进行充电。
请参考图3，为本申请实施例提供的一种充电定位逻辑的示意图。如图3所示，天线模组制作成充电壳并与终端匹配安装，终端在充电时，若选择进行无线充电，则终端系统将向已连接的待充电设备发送第一控制指令，使待充电设备开启红外接收功能，并且，终端系统将调用对应匹配的待充电设备编码对信号进行调制，并通过红外发射灯进行发射，待充电设备则通过红外接收灯接收红外信号进行解码，并将解码信息反馈给终端，从而实现终端对待充电系统的定位。
总之，在本申请实施例中，通过利用终端与天线模组连接，两者组合加载至常规充电器上即可实现无线充电功能，可以通过终端快速定位、匹配已连接的待充电设备，从而缩短充电协商所需的时间，提高充电效率。
下面介绍上述实施例中提及的无线充电设备。
本申请另一方面实施例还提供了一种无线充电设备，所述无线充电设备包括终端以及与所述终端可拆卸连接的天线模组，所述天线模组与所述终端的外形相适配，所述终端具有有线充电接口，所述有线充电接口可与有线充电器连接。
其中，所述终端与所述天线模组之间的连接可以包括电连接，以实现信号传输，还可以包括结构上的连接，例如两者呈可拆卸式连接，以方便天线模组拆离或安装。所述终端具有有线充电接口，所述终端可以通过有线充电接口可与有线充电器连接，也就是说，终端与天线模组连接，而终端则通过与有线充电器连接，即可实现两者的组合加载至常规充电器上，从而实现无线充电功能，可以通过终端快速定位、匹配已连接的待充电设备，从而缩短充电协商所需的时间，提高充电效率。
本申请的一些实施例中，所述天线模组包括至少一个天线片，在所述天线片的数量为多个的情况下，多个所述天线片中的至少两个可在同一平面内展开。
在一些实施例中，在天线片的数量为一个时，该一个天线片可以为位于其预设方位角范围内的待充电设备进行充电；在天线片的数量为多个时，各 天线片可以单独为位于各自预设方位角范围内的待充电设备进行充电，也可以至少两个天线片组成一个天线为位于其预设方位角范围内的待充电设备进行充电。例如，所述预设方位角范围可以是所述天线片正对的±60°的范围内，即在水平方向上为±60°、在竖直方向上为±60°所限定出的范围内。
也就是说，至少两个天线片可以在同一平面内展开，使在同一平面内展开的至少两个天线片合为一个，从而通过多个天线片合为一个共同对一个待充电设备进行充电，可以有效提高无线充电的效率。
本申请的另一些实施例中，所述天线模组还包括圆极化合成网络以及至少一个扫描馈电网络，所述至少一个扫描馈电网络与所述圆极化合成网络连接，所述圆极化合成网络与所述天线片连接。
请参考图4，为本申请实施例提供的一种天线模组的示意图。如图4所示，示例性的，所述天线模组包括至少一个天线片41，还包括圆极化合成网络42、第一扫描馈电网络43、第二扫描馈电网络44以及第三扫描馈电网络45，所述第一扫描馈电网络43、第二扫描馈电网络44以及第三扫描馈电网络45均与所述圆极化合成网络42连接，所述圆极化合成网络42与所述天线片41连接。第一扫描馈电网络43、第二扫描馈电网络44以及第三扫描馈电网络45可以实现不同角度的扫描馈电。可选的，第一扫描馈电网络43为30°扫描馈电网络，第二扫描馈电网络44为45°扫描馈电网络，第三扫描馈电网络45为60°扫描馈电网络，从而实现天线模组在30°、45°以及60°方向上的扫描馈电。
在本申请的另一些实施例中，所述天线片设置于所述终端的背面，并与所述终端可拆卸地连接，所述天线片包括沿所述终端的长度方向依次设置的可独立工作的第一天线块、第二天线块和第三天线块。
示例性的，所述终端为手机，可以将所述天线模组制作成与手机壳相同或类似的形状，例如在天线片四周增加硅胶套制成手机壳，或者制作成与手机的背面形状相适配的形状，以方便将天线模组可拆卸地设置在终端的背面，方便携带，并且基本不影响终端的正常使用，此时，可以多个天线片折 叠后作为整体设置在终端的背面，也可以仅将一个天线片设置在终端的背面。
请参考图5，图5为本申请实施例提供的一种天线片的结构示意图。如图5所示，所述天线片41呈矩形，所述天线片41包括沿其长边依次设置的可独立工作的第一天线块411、第二天线块412和第三天线块413，第一天线块411、第二天线块412和第三天线块413占所述天线片41的总面积的比例可以根据实际需求进行设定，本申请不做具体限定。
考虑到天线设备于终端背面时，若用户正在使用所述终端，则可能对天线模组产生遮挡，影响发射效率，因此，所述天线片的第一天线块、第二天线块和第三天线块可以独立工作，由此，可以结合电平的高低以及终端的姿态，判断出所述第一天线块、所述第二天线块、所述第三天线块中哪一部分被遮挡，从而控制未被遮挡的部分向位于所述天线片的预设方位角范围内的待充电设备进行充电，从而提高充电效率，减少充电损耗，并且不影响终端的正常使用。
请参考图6，图6为本申请实施例提供的天线单元的示意图。如图5和图6所示，本申请的再一些实施例中，所述天线片包括阵列分布的多个天线单元414，每一所述天线单元414包括呈45°交叉设置的两根辐射体4141，每一所述辐射体4141与所述天线片41的长边所成的角度均为45°。
现有技术中，当阵列天线工作于20GHz时，使阵列天线不出现栅瓣的最大天线单元尺寸为λ/2，其中λ是20GHz所对应的波长，即15mm。为降低栅瓣出现的风险，初始单元设置为14mm×14mm，常规的天线单元设置方式通常为沿正X、正Y排布，即若阵列天线为平面阵列天线，平面为矩形，则天线单元中的辐射体为沿矩形的长边、短边排布。然而，本申请实施例中，所述天线片41中的每一天线单元414中的两根辐射体4141均呈交叉设置，并且，每一所述辐射体4141与所述天线片41的长边所成的角度均为45°，采用这样的布设方式，也即对辐射体4141进行45°旋转，保证了单极化天线在激励时，接收天线无论处于水平或垂直极化方向都能接收到电磁波辐 射，从而增大了无线充电的可用范围；并且，还可以在相同面积上排布更多的天线单元，或者说在排布相同数量的天线单元时可以缩小占用的面积(仅为原来面积的73％)，因此，单个天线片41的总增益可以提升1.51dB，由于斜45°极化与垂直/水平极化天线之间存在极化失配，这将损失1.5dB，两相抵消，因此天线增益变化极小，并且，本申请实施例中的天线片在全极化接收电磁波下均可正常工作。
请参考图7，图7为本申请实施例提供的天线增益与扫描角度的关系示意图。图7中，线条④表示采用现有技术排布的天线在扫描角度为0°时的天线增益，线条⑤表示采用现有技术排布的天线在扫描角度为30°时的天线增益，线条⑥表示采用现有技术排布的天线在扫描角度为60°时的天线增益，线条⑦表示采用本申请实施例方案排布的天线在扫描角度为0°时的天线增益，线条⑧表示采用本申请实施例方案排布的天线在扫描角度为30°时的天线增益，线条⑨表示采用本申请实施例方案排布的天线在扫描角度为60°时的天线增益。可以看到，本申请实施例中，通过将辐射体设置成上述形式，可以使天线增益几乎保持不变，同时，在相同面积上可以排布更多的天线单元。
如图6所示，本申请的再一些实施例中，可选的，辐射体4141的两端设置有与辐射体4141垂直的矩形条4142，通过增加所述矩形条4142，可以优化辐射体4141末端开路引起的电磁波反射，实现2GHz宽带范围内天线模组的正常工作，使所述天线模组可以适应多种环境工作。可选的，辐射体4141与矩形条4142可以一体成型。
请参考图8，图8为本申请实施例提供的天线的驻波比与频率的关系示意图。图8中，线条①表示未经优化的偶极天线不扫描时的驻波比，线条②表示未经优化的偶极天线扫描60度时的驻波比，线条③表示优化后的偶极天线不扫描时的驻波比，线条④表示优化后的偶极天线扫描60度时的驻波比。可以看到，本申请实施例中，通过在辐射体4141的两端设置矩形条4142优化末端开路引起的电磁波反射，并对矩形条4142的长宽进行优化后，实 现了在2GHz的带宽范围内天线的正常工作，优化后的天线的驻波比比未经优化的天线的驻波比更小，性能更优。
请参考图9至图11，图9为本申请实施例提供的天线片的组合形态示意图之一，图10为本申请实施例提供的天线片的组合形态示意图之二，图11为本申请实施例提供的天线片的组合形态示意图之三。如图9至图11所示，本申请的一些实施例中，可选的，所述天线装置包括四个天线片41，其中，图9中的四个天线片41在同一平面内展开合为一体，此时天线增益相较于单个天线片41而言可以提升6dB，因此电源可以通过降低6dB的发射功率，从而保证和单个天线片41下的输出功率相同，此时，相较于单个天线片41而言，功耗仅为原来的25％，极大程度地降低了功耗；图10中的四个天线片41每两个在同一平面内展开合为一体，则二合一的天线片的天线增益相较于单个天线片41而言可以提升3dB，因此电源可以通过降低3dB的发射功率，从而保证和单个天线片41下的输出功率相同，此时，相较于单个天线片41而言，功耗仅为原来的50％，极大程度地降低了功耗；同样的，若三个天线片41在同一平面内展开合为一体，则三合一的天线片的天线增益相较于单个天线片41而言可以提升4.8dB，因此电源可以通过降低4.8dB的发射功率，从而保证和单个天线片41下的输出功率相同，此时，相较于单个天线片41而言，功耗仅为原来的33％，极大程度地降低了功耗；图11中的四个天线片41围合形成长方体，也就是说，四个天线片41独立工作，每一个天线片41分别负责落在其90°范围内的待充电设备进行充电，该状态下，每一个天线片41的辐射方向均不相同，无法通过提升增益的方式降低功耗，但是该状态下，天线波束最宽，覆盖范围最广，每一个天线片41可以动态调整位置，如此，可以兼顾四周各向的充电需求。
本申请实施例提供的无线充电设备能够实现图1至图3的方法实施例实现的各个过程，为避免重复，这里不再赘述。
在本申请实施例中，通过利用终端与天线模组连接，两者组合加载至常规充电器上即可实现无线充电功能，可以通过终端快速定位、匹配已连接的 待充电设备，从而缩短充电协商所需的时间，提高充电效率。
