具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例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公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
在无线充电设计和应用过程中，充电设备的发射线圈和待充电设备的接收线圈是否对准对无线充电效率有很大影响。在实际使用过程中，由于接收线圈在待充电设备的位置不同而导致使用者在放置待充电设备时接收线圈相对发射线圈发生偏移，因此提醒使用者放置待充电设备的位置对提高无线充电效率有重大意义。
本公开至少一实施例提出了一种无线充电装置，能够在一定程度上解决无线充电中接收线圈和发射线圈的对准问题。
图1为本公开至少一实施例提供的无线充电装置的示意框图。如图1所示，所述无线充电装置10包括发射线圈11、第一通信器12、控制器13和 提示器14。所述第一通信器12配置为接收待充电设备20的设备信息。该设备信息例如包括该待充电设备的型号信息、物理地址(MAC地址)等信息。根据该设备信息可以对该待充电设备20的身份进行确定，从而获得该待充电设备20的形状、尺寸等信息，并可以获得该待充电设备中的接收线圈在该待充电设备中的相对位置信息。本公开实施例对于该待充电设备的类型不作限制，例如包括但不限于手机、平板电脑、电子书等。例如，当该待充电设备20为手机的情形，该设备信息可以包括如iphone X、iphone Xs max等型号信息。
例如，该第一通信器12可以通过无线连接通过网络与该待充电设备20或其它电子设备进行无线通信，该网络例如为因特网、内部网和/或诸如蜂窝电话网络之类的无线网络、无线局域网(LAN)和/或城域网(MAN)。无线通信可以使用多种通信标准、协议和技术中的任何一种，包括但不局限于全球移动通信系统(GSM)、增强型数据GSM环境(EDGE)、宽带码分多址(W-CDMA)、码分多址(CDMA)、时分多址(TDMA)、蓝牙、Wi-Fi(例如基于IEEE 802.11a、IEEE 802.11b、IEEE 802.11g和/或IEEE802.11n标准)、基于因特网协议的语音传输(VoIP)、Wi-MAX，用于电子邮件、即时消息传递和/或短消息服务(SMS)的协议，或任何其他合适的通信协议。
所述控制器13配置为根据所述设备信息获取所述待充电设备20的接收线圈21在该待充电设备20中的相对位置信息(参考图2所示)，根据所述相对位置信息提示器控制提示器14发出提示信息，以指示所述待充电设备20的放置位置，从而使所述发射线圈11与接收线圈21对准。
例如，该控制器13可以为硬件、软件、固件以及它们的任意可行的组合。例如，该控制器13可以为专用或通用的电路、芯片或装置等，也可以为处理器和存储器的结合。
例如，处理器可以是中央处理单元(CPU)、图形处理单元(GPU)、数字信号处理器(DSP)或者具有数据处理能力和/或程序执行能力的其它形式的处理单元，例如现场可编程门阵列(FPGA)等；例如，中央处理单元(CPU)可以为X86或ARM架构等。处理器可以为通用处理器或专用处理器，可以控制无线充电装置10中的其它组件以执行期望的功能。
例如，存储器可以包括一个或多个计算机程序产品的任意组合，计算机程序产品可以包括各种形式的计算机可读存储介质，例如易失性存储器和/或非易失性存储器。易失性存储器例如可以包括随机存取存储器(RAM)和/或高速缓冲存储器(cache)等。非易失性存储器例如可以包括只读存储器(ROM)、硬盘、可擦除可编程只读存储器(EPROM)、便携式紧致盘只读存储器(CD-ROM)、USB存储器、闪存等。在计算机可读存储介质上可以存储计算机程序指令，例如一个或多个计算机程序模块，处理器可以运行该计算机程序指令，以实现控制器13的各种功能。在计算机可读存储介质中还可以存储各种应用程序和各种数据以及应用程序使用和/或产生的各种数据等。
例如，如图2所示，所述相对位置信息指代的是所述接收线圈21在所述待充电设备20中的所处位置，也可以包括以所述待充电设备20的中心或一角为坐标原点建立坐标系，该接收线圈21处于该坐标系中的坐标信息；例如，当该待充电设备20为四边形，例如为矩形的情形，所述接收线圈21的相对位置信息包括：所述接收线圈21的中心到所述待充电设备的四个边的垂直距离，如图2所示，所述相对位置信息还可以是指接收线圈21的中心与待充电设备20的四条边的垂直距离d1、d2、d3和d4；例如，该接收线圈的相对位置信息包含了该待充电设备的尺寸信息。例如，所述相对位置信息可以是所述无线充电装置根据所述设备信息从其本地的存储器中调取或从网络中获取的。
从上述实施例可以看出，本公开实施例提供的无线充电装置，通过接收待充电设备的设备信息进而获取相应的相对位置信息，以所述发射线圈与接收线圈对准为目的，控制提示器发出提示信息，以指示所述待充电设备的放置位置；这样，当用户将所述待充电设备放置在该放置位置时，可实现线圈对准，从而提高了充电效率。
图3B和图3A分别示出了本公开至少一实施例提供的无线充电装置的平面示意图和剖视图的一个示例，如图3A和3B所示，所述无线充电装置10还包括承载面151，该承载面151配置为放置所述待充电设备20；该发射线圈11、第一通信器12、控制器13和提示器14均位于该承载面151远离该待充电设备的一侧。该提示信息包括位于承载面151的光投影30，该光 投影30界定待充电设备20的放置位置。例如，该承载面151为平面。
本公开实施例对于无线充电装置10中的各部件，如承载面151、发射线圈11、第一通信器12、控制器13和提示器14之间的位置关系和组装方式不作限定。在一个示例中，如图3A所示，该无线充电装置10包括具有该承载面151的装置主体15，该装置主体150包括腔体150，该发射线圈11、第一通信器12、控制器13和提示器14均设置于该腔体150内。
如图3A所示，所述提示器14包括发光元件141，该发光元件141配置为在控制器13的控制下发出光线并将所述光线投射到承载面151形成该光投影30，该提示信息包括所述发光元件141发出的光线投射到承载面151上形成的光投影30。这样，通过光线投射的方式，使配置为放置所述待充电设备20的承载面151上形成由光投影30组成的提示信息，从而指示用户将待充电设备放置在光投影30所形成的区域，以实现发射线圈11和接收线圈21的对准。
例如，图3A示出了该发光元件141从该承载面151远离该发射线圈11的一侧对该承载面151进行投影，然而本公开实施例对此不作限制，该发光元件141也可以从该承载面151靠近该发射线圈11的一侧对该承载面151进行投影。
例如，该待充电设备20的放置位置为矩形区域，光投影30包括至少两个线形光投影，以指示该矩形区域的至少两个边，从而界定该矩形区域。
例如，该光投影30指示该矩形区域的相邻两个边，用户可以根据该相邻两个边确定该矩形区域并放置该待充电设备，使得接收线圈和发射线圈对准。
例如，该光投影30指示该矩形区域的相对两个边，用户可以根据该相对的两个边确定该矩形区域的相对两条边，例如该矩形区域的长边或短边；然后可以根据该相对两条边大致确定该矩形区域的另外两条边的位置。例如，另外两条边相对于该确定的两条边对称。
在另一些示例中，该光投影30指示该矩形区域的四条边，如图3B所示，用户可以直接将该待充电设备放置于该矩形区域，实现接收线圈和发射线圈的对准。
例如，该提示信息包括待充电设备的放置方向信息，该提示信息还指示该待充电设备的放置方向。
例如，该控制器还配置为根据该接收线圈在该待充电设备中的相对位置信息获取该待充电设备的放置方向信息，并控制该提示器发出包括放置方向信息的提示信息。例如，该光投影30还包括该放置方向信息。
例如，该至少两个线光源分别配置为发出不同颜色的光以形成不同颜色的线形光投影，以指示待充电设备20的放置方向，也即该待充电设备10的不同侧边对应的位置。例如，不同颜色的线形光投影分别指示该待充电设备20的不同侧边的对应位置。例如，当接收线圈21并不位于该待充电设备20的中心位置时，需要确定该待充电设备20的放置方向。
例如，该发光元件141包括至少两个线光源，该至少两个线光源分别配置为形成所述至少两个线形光投影。线光源是指能发出平行光线的光源，从而可以在投影面形成线形的光投影。
需要说明的是，本公开实施例中的光源包括直接发光光源或者直接发光光源与导光元件的组合。例如，该线光源可以包括能直接发出平行光线的光源，或者包括光源(如LED)与导光元件的组合。
例如，如图3A所示，线光源142的数量可以是两个，两个线光源142对称设置在所述装置主体15两个侧边，从而对待充电设备的放置位置进行一定程度上的指示，可以是待充电设备的短边或长边所需对准的位置，取决于两个线光源142具体设置在装置主体15的两个短侧边还是长侧边。以下结合附图对本公开实施例提供的线光源及其工作方式进行示例性说明，然而并不作为对本公开的限制。
图4示出了本公开另一些实施例提供的无线充电装置10的平面示意图，图5A-图5B为图4沿剖面线A-A’的剖视图的一个示例，图5C为图4沿剖面线B-B’的剖视图的一个示例。
例如，如图4所示，该发光元件141包括四个线光源142，四个线光源142分别设置在装置主体15的四个侧边，即所述装置主体15的每条侧边对应设置一个线光源142。这样，四个线光源142所发射出的光线在所述承载面151上形成的光投影30能够形成矩形区域(如图3B所示)，从而能够更 好地形成一个贴近于待充电设备形状的光投影作为提示信息，更加方便用户操作。例如，该光投影可以在该四个线光源142位于该承载面151的正投影所围成的区域的内部(如图4所示光投影30a)，该光投影也可以位于该四个线光源142在该承载面151的正投影所围成的区域的外部(如图4所示光投影30b)，该光投影也可以与该四个线光源在该承载面151的正投影所围成的区域发生交叠，本公开实施例对此不作限制。
需要说明的是，所述线光源142发出的光可以是具有颜色的，在必要的情况下，为了保证其准直性，可以采用激光光源形成该线光源。
在另一些示例中，该线光源由条形灯具构成，该条形灯具的表面包裹具有狭缝的不透光涂层，该狭缝与该灯具的长度方向平行，从而使得光线仅能从该狭缝射出形成单一方向的平行光。例如，该条形灯具中容纳有线状排列的多个LED。
在又一些示例中，结合参考图5A-图5C，每个线光源142包括光源144和导光柱143，该导光柱的轴线方向(长度方向)平行于该承载面151设置，光源144设置于该导光柱143的一端，光源144发出的光线从该导光柱143的一端射入并均匀地从该导光柱143的侧面射出。例如，该导光柱143的材料为透明材料，如丙烯酸树脂、聚碳酸酯、环氧树脂、玻璃等。例如，该光源144可以是发光二极管(LED)。
该导光柱143的表面包裹具有狭缝140的不透光涂层，该狭缝140与该导光柱143的轴线方向平行从而将从该导光柱侧面射出的光线限制在单一方向以形成线光源(平行光)。
在一些示例中，提示器14还包括至少两个旋转器，该至少两个旋转器与至少两个线光源142一一对应设置，至少两个旋转器中的每个配置为旋转所对应的线光源142中的导光柱143以改变所对应的线光源的出光方向，从而改变该线光源在承载面151上形成的线形投影的位置。例如，如图5C所示，每个导光柱143对应的旋转器145设置于该导光柱143远离其对应的光源144的另一端。例如，该旋转器可以实现为电机。
图5A和5B分别示出了该线光源在该旋转器的作用下、从承载面151靠近发射线圈11的一侧(也即腔体150内)将光线L向承载面151上进行 投影形成不同位置的光投影30的示意图。在这种情形，为了使得光线L顺利射出腔体150到达承载面151，该承载面151的材料可以是透明的或半透明的。
如图5A所示，该光投影可以位于该四个线光源142在该承载面151的正投影所围成的区域的内部，形成如图4所示光投影30a；如图5B所示，该光投影也可以位于该四个线光源142在该承载面151的正投影所围成的区域的外部，形成如图4所示光投影30b。
例如，所述控制器13配置为根据设备信息待充电设备中接收线圈的相对位置信息控制每个旋转器145旋转所对应的线光源142，以改变所对应的线光源在承载面151上形成的线形投影的位置，从而指示待充电设备20的放置位置。
例如，该控制器13配置为结合所述接收线圈的相对位置信息生成所制指令，以控制所述导光柱的旋转角度，使其投射到所述平面上形成的光投影与所述待充电设备的尺寸相匹配。
例如，所述控制器13，可配置为：根据所述待充电设备的接收线圈的相对位置信息，以及发射线圈在无线充电装置中的相对位置关系，计算出在所述待充电设备的接收线圈与所述发射线圈对准时，该待充电设备边缘轮廓的矩形区域在以所述发射线圈的中心为坐标原点的直角坐标系中的位置；生成所述线光源142的控制指令，所述控制指令包括控制所述线光源142的旋转角度的指令，以使其投射到所述承载面151上形成的光投影30形成与所述待充电设备的尺寸相匹配的所述矩形区域。这样，当形成所述矩形区域后，用户将待充电设备放入所述矩形区域并与所述矩形区域的形状相契合，即能完成线圈对准。
图9示出了接收线圈与发射线圈的对准方法的计算示意图。
以无线充电装置的其中一角为坐标原点建立xoy坐标系并确定发射线圈(例如中心点)在该xoy坐标系的位置，同时以待充电设备的其中一角为坐标原点建立x’o’y’坐标系，并根据所述接收线圈的相对位置信息确定确定接收线圈(例如中心点A)在x’o’y’坐标系中的位置，将该A点在x’o’y’坐标系中的坐标与发射线圈11在xoy坐标系的坐标统一，则可以得 到两个坐标系之间的映射关系：
Figure PCTCN2019128765-appb-000001
通过上述映射关系，可以得到所述待充电设备的边缘(如四个侧边)在xoy坐标系下的坐标，即待充电设备在承载面151的放置位置。
在计算得到待充电设备的放置位置后，即可知道各线光源142在所述承载面151上需要形成的光投影30的位置，从而计算得到导光柱相应的旋转角度θ。
如图5A和5B所示所示，假定该导光柱143上的狭缝140的初始位置为正对该承载面151(也即位于最顶端)，该导光柱143到该承载面151的垂直距离为h。
当检测到该放置位置位于该四个导光柱143在该承载面151的正投影所围成的区域的内部，D和D’分别为接收端相对于各导光柱143的轴线在该承载面151的正投影的最近距离，控制器13控制各旋转器将其对应的导光柱143旋转的角度旋转角度θ’(顺时针)和θ(逆时针)满足：
tanθ＝D/h，tanθ’＝D’/h。
当检测到该放置位置位于该四个导光柱143在该承载面151的正投影所围成的区域的外部，控制器13控制各旋转器将其对应的导光柱143旋转的角度旋转角度θ’(逆时针)和θ(顺时针)满足：
tanθ＝D/h，tanθ’＝D’/h。
在另一些示例中，发光元件141可以从该承载面151远离该发射线圈11的一侧对该承载面151进行投影。例如，该提示器14还可以包括伸缩器，该伸缩器与该发光元件141连接，并允许发光元件141相对于承载面151突出且与承载面151的距离可变。
图6A和图6B分别为图4沿剖面线A-A’和B-B’的剖视图的另一个示例。如图所示，该提示器14还包括与每个线光源142对应的支撑壳146及伸缩器152，每个支撑壳146用于容纳并固定对应的线光源142，并与对应的伸缩器152连接。该支撑壳146可以对该线光源142形成保护。例如，该支撑壳146可以为塑料、陶瓷、金属等材料。
例如，该伸缩器152可以实现为弹簧、丝杠等可伸缩装置。例如，如图6A-6B所示，该伸缩器152包括分别与该支撑壳146的两端分别连接的两个弹簧。当弹簧处于拉伸状态，可以使得该发光元件141伸出该装置主体15，上升至该承载面151远离该腔体150的一侧，从该承载面71的上方向该承载面71进行投影。当弹簧处于压缩状态，可以使得该发光元件141收纳于该腔体150内，从而便于携带、更加美观。
例如，该装置主体15在对应于该支撑壳146的位置设置有窗口160，以允许该支撑壳146伸出。
例如，每个支撑壳146在对应于导光柱142的位置具有开口170以允许光线射出。
图6A-图6B示出了本公开实施例提供的无线充电装置中发光元件141在腔体150中向该承载面151投射光线L形成光投影30的示意图。
图7A-图7B示出了本公开实施例提供的无线充电装置中发光元件141在承载面151远离腔体150一侧(腔体150外)向该承载面151投射光线L形成光投影30的示意图。在这种情形，该承载面131的材料可以是不透光的。当弹簧处于拉伸状态，可以使得该发光元件141伸出该装置主体15，上升至该承载面151远离该腔体150的一侧。
在这种情形，导光柱(通常由电机带动旋转)旋转角度的计算方法如图10所示。
如图10所示，D和D’为接收线圈相对于各导光柱143的轴线在该承载面151的正投影的最小距离，h为导光柱所处高度，θ和θ’为左右两侧导光柱所需旋转的角度。假设初始时，导光柱漏光的部分(狭缝140)位于最底端，那么导光柱的旋转角度θ(顺时针)和θ’(逆时针)满足：
tanθ＝D/h，tanθ’＝D’/h，
由此可以计算出导光柱的旋转角度，根据这个角度控制电机带动导光柱旋转，从而提醒使用者接收端的摆放位置。
当然，上述计算方式仅仅示意性地计算了两侧的导光柱旋转角度，当无线充电装置的四周均设置导光柱时，同理可以知道另外两侧的导光柱的旋转角度，在此不再赘述。
图8A和图8B示出了该无线充电装置的另一种工作示意图，适用于当待充电设备20的面积大于承载面151的面积的情形。
如图8A所示，该发光元件141从该承载面151远离发射线圈11的一侧向该承载面151进行投影，当该光投影至少部分超出该承载面151，该光投影30形成在用于承载该无线充电装置10的支撑物180的表面，以指示该待充电设备20的放置位置；例如可以等待一定时间(如3秒)使得用户可以识别出该光投影30，然后该伸缩元件152在控制器13的控制下收缩，使得发光元件141缩回至该承载面151以下，例如收纳于该腔体150中，从而不影响待充电设备20在该承载面151上的放置；用户可以根据该光投影的位置30放置该待充电设备20，从而将接收线圈21与发射线圈11对准，如图8B所示。
在这种情形下的导光柱的旋转角度可以参考前述实施例，此处不再赘述。
需要说明的是，由于光投影并不能指示方向，在必要时，需要另外标识出待充电设备的放置方向，如通过使导光柱发出不同的颜色来表示待充电设备的顶部朝向，或者，直接在无线充电装置的靠近两短边的位置分别设置发光元件，点亮某一侧的发光元件则为待充电设备的顶部朝向，这里的顶部例如可以是指手机、平板电脑等的前置摄像头的放置位置一端。这样，通过增加设置对放置方向的指示，使得待充电设备在放置时能够正确摆放，以防止线圈不能对准的情况发生。
图11A为本公开另一些实施例提供的无线充电装置的示意图，例如，如图11A所示，该无线充电装置可以包括多个发射线圈11，从而可以同时对多个待充电设备充电。
如图11A所示，所述提示器14还包括辅助发光元件147；例如，所述辅助发光元件147发光元件设置在所述装置主体15的配置为放置所述待充电设备20的承载面151上，配置为发出辅助提示信息。这样，利用辅助发光元件147发光元件发出辅助提示信息，能够更好地实现提示作用，有利于线圈对准。例如，该辅助发光元件147可以具有与发光元件141类似的结构。
这里所述的辅助提示信息，可以是在前述的发光元件141所发出的提示信息的基础上，给出辅助性的提示信息。例如，对于比较靠近无线充电装置边缘的位置，导光柱发出的光线可能无法照到，利用设置在该位置的辅助发光元件147发光元件来进行提示；或者，发光元件该辅助发光元件可以帮助提示待充电设备的放置方向。
例如，当无线充电装置包括两个或多个发射线圈时，可以实现同时对两个以上的待充电设备进行充电，但是也需要分别实现线圈对准。但是，多个待充电设备之间的相互阻挡，可能导致导光柱发出的光线无法投射到指定位置的问题。因此，作为本公开的一个可选实施方式，如图11A所示，通过在无线充电装置上设置辅助发光元件147配置为解决导光柱光线被遮挡的问题。
例如，对于每个发射线圈11，其周围可布设多个辅助发光元件147，所述辅助发光元件147可以是点状或条状的发光元件(例如发光二极管LED)。点状发光元件可以是以发射线圈为中心呈阵列排布的；条状发光元件可以是以四条发光元件为一组，组成矩形，并由多个矩形形成嵌套排布，参见图11A所示。可选的，所述控制指令还可以包括控制相应的发光元件点亮的指令(假设发光元件的初始状态为熄灭状态)，点亮的发光元件配置为给出相应的辅助提示信息。
例如，所述控制器13还可具体配置为：根据所述待充电设备中所述接收线圈的相对位置信息，结合所述提示器与发射线圈的相对位置关系，在以所述发射线圈的中心为坐标原点的直角坐标系上，计算出在所述待充电设备的接收线圈与所述发射线圈对准时，该待充电设备边缘轮廓的矩形区域；生成位于所述矩形区域边界处的至少一个辅助发光元件147发光元件的点亮指令，以点亮相应的辅助发光元件147发光元件从而指示待充电设备的放置位置。
例如，所述装置主体15的腔体150中可以布设所述发射线圈10、第一通信器20和控制器30；所述辅助发光元件147发光元件可以布设在所述装置主体15之外，也可以布设在所述装置主体15的腔体150内。
图11B示出了所述无线充电装置的一个剖视图，所述辅助发光元件147 发光元件可以是布设在装置主体15配置为放置待充电设备的承载面151上。图11C示出了所述无线充电装置的另一个剖视图，所述辅助发光元件147发光元件也可以是布设在装置主体15配置为放置待充电设备的承载面151的下方。
当所述辅助发光元件147发光元件布设在所述承载面151下方时，为了使光线能够出射到装置主体15之外，所述承载面151可以是透明的或半透明的。当承载面151为半透明时，所述辅助发光元件147发光元件需要尽量靠近所述承载面151，以使光线能够最大程度射出所述装置主体15。同时，可以看到，当所述辅助发光元件147发光元件设置在装置主体15内时，辅助发光元件147发光元件的排布就不会影响到待充电设备的放置；此外，当所述承载面151为半透明状态时，能够在一定程度上模糊辅助发光元件147发光元件的外形、轮廓，从而使得无线充电装置的外形更加美观。
例如，如图1和图3A所示，所述无线充电装置10还包括存储器16，配置为存储所述待充电设备20的接收线圈21的相对位置信息；所述接收线圈的相对位置信息及所述待充电设备20的设备信息彼此关联。
例如，该存储器可以包括一个或多个计算机程序产品的任意组合，计算机程序产品可以包括各种形式的计算机可读存储介质，例如易失性存储器和/或非易失性存储器。易失性存储器例如可以包括随机存取存储器(RAM)和/或高速缓冲存储器(cache)等。非易失性存储器例如可以包括只读存储器(ROM)、硬盘、可擦除可编程只读存储器(EPROM)、便携式紧致盘只读存储器(CD-ROM)、USB存储器、闪存等。
例如，该存储器可以是该控制器内部的存储器，也可以与该控制器分别设置。
例如，控制器13配置为从所述存储器中获取所述接收线圈的相对位置信息；或者，控制所述第一通信器根据所述待充电设备的设备信息从网络中获取所述接收线圈的相对位置信息。
例如，当控制器13从第一通信器接收到待充电设备20的设备信息后，即可从本地的存储器16中调取与该设备信息相关联的接收线圈的相对位置信息，进而配置为处理得到相应的控制指令以使提示器14发出提示信息。
例如，当存储器16中未存储与所述获取的待充电设备的设备信息关联的接收线圈的相对位置信息时，控制器13控制所述第一通信器根据所述待充电设备的设备信息从网络中获取所述接收线圈的相对位置信息，从而获取所述接收线圈的相对位置信息；例如，该控制器13还可以将该从网络中获取的接收线圈相对位置信息存储于存储器16中。
例如，如图1和图3A所示，所述第一通信器12，还配置为根据所述待充电设备20的设备信息，从网络中获取所述待充电设备20的接收线圈21的相对位置信息。
例如，该第一通信器12根据该待充电设备的设备信息在网络上查询或按照大数据分析得到待充电设备的最可能的接收线圈相对位置。

例如，所述存储器16还可以配置为存储所述从网络中获取的待充电设备20的接收线圈的相对位置信息。
此外，当同时结合存储器16的存储功能和第一通信器12的网络获取功能时，所述存储器16和第一通信器12可以互补，进一步提高了无线充电装置的通用性。例如，在本地调取先于网络获取的技术方案中，当存储器16中没有存储所述尺寸信息和相对位置信息时，可以利用第一通信器12从网络中获取；或者，在网络获取先于本地调取的技术方案中，当第一通信器12不能从网络中获取尺寸信息和相对位置信息时，可以从本地的存储器16 中搜索可用信息。

在另一些示例中，例如，该第一通信器12可以同时充当该传感器以检测是否有待充电设备靠近。例如，当待充电设备靠近时，第一通信器12可以获取该待充电设备的设备信息，例如物理地址(MAC地址)等，从而检测到有待充电设备靠近。例如，第一通信器12还可以根据接收信号强度值(Received Signal Strength Indication，RSSI)来判断是否有待充电设备靠近。本公开至少一实施例还提出了一种无线充电方法，适用于上述无线充电设备，该方法能够在一定程度上解决无线充电线圈的对准问题。
如图12A所示，所述无线充电方法包括以下步骤：步骤41：接收待充电设备的设备信息；步骤42：根据所述设备信息获取所述待充电设备的接收线圈的相对位置信息；以及步骤43：根据所述相对位置信息发出提示信息，以指示所述待充电设备的放置位置。

例如，在开始时，查询传感器是否检测到有电子设备正在充电，如果是，则重复上述检测过程；如果否，则检测是否有待充电设备靠近，如果是，则控制第一通信器从该待充电设备获取该充电设备的设备信息。当发光元件需要从承载面上方向下进行投影时(如图7A-7B和如图8A-8B所示)，此时可以控制伸缩器以将该发光元件升高到位于承载面以上的一定高度。接着，查询存储器中是否存储有当所述获取的待充电设备的设备信息存储于所述无线充电装置的存储器中时，从所述存储器中获取所述接收线圈的相对位置信息；当与所述获取的待充电设备的设备信息相关联的接收线圈的相对位置信息存储于所述存储器中时，从所述存储器中获取所述接 收线圈的相对位置信息；当与所述获取的待充电设备的设备信息相关联的接收线圈的相对位置信息未存储于所述存储器中时，控制所述第一通信器根据所述待充电设备的设备信息从网络中获取、或者根据大数据分析获取接收线圈的相对位置信息。
