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。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。
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控制方法进行详细地说明。
请参照图1至图12，本发明实施例提供了一种无线充电装置，包括：
底座1；固定于所述底座1上的轨道支架22；与所述轨道支架22活动连接的滑轨23；与所述滑轨23活动连接的N个天线3，N为大于1的整数；其中，所述滑轨23相对于所述轨道支架22在第一状态和第二状态之间往复运动；所述天线3在所述滑轨23上往复运动，以调整所述天线3的发射位置和发射方向。
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。
需要指出，以手机为例，受天线方向性的影响，发射天线和接收天线在不同位置与角度时，其能量传输效率是不同的，两者距离较近且角度较好时能量传输效率高，两者距离较远或角度较差时能量传输效率低，甚至出现不能正常匹配的情况。
该实施例中，通过滑轨23相对于所述轨道支架22在第一状态和第二状态之间往复运动，以及天线3在滑轨上往复运动，来调整所述天线3的发射位置和发射方向，即调整天线3的发射角度，以及调整天线3与待充电设备5之间的位置关系，从而优化发射天线3与待充电设备5的接收天线之间的能量传输效率，使发射天线3与接收天线耦合度最高，达到提高待充电设备5摆放的灵活度，并减少能量损耗，提高无线充电效率的效果。因此，该实施例能够解决在多个设备存在充电需求时，存在的充电耗时长、充电效率低的问题，且不便于收纳与携带。
需要指出的是，滑轨23和天线3的往复运动可以基于用户的输入进行控制，如用户手动调整滑轨23和天线3的位置；或者也可以基于待充电设备5的放置位置进行自动控制。
作为一种示例，在为多个设备进行充电时，无线充电装置通过调整天线3位置，从N个所述天线中确定与多个待充电设备匹配成功且充电效率大于预设阈值的M个目标天线，M为小于或等于N的正整数。
在一实施例中，所述装置还包括：控制单元和位置检测单元；其中，所述位置检测单元与所述控制单元通信连接，所述位置检测单元用于获取待充电设备5的位置信息；所述控制单元用于根据所述位置信息，控制所述滑轨23相对于所述轨道支架22在第一状态和第二状态之间往复运动，以及控制所述天线3在所述滑轨23上往复运动。
该实施例中，通过位置检测单元能够获取待充电设备5的放置的位置信息，从而控制单元根据该位置信息，自动控制滑轨23和天线3移动，以调整 天线3的发射角度，以及调整天线3与待充电设备5之间的位置关系。
在一实施例中，所述滑轨23为环状结构，所述第一状态和所述第二状态是绕所述滑轨23的径向转轴，相对于所述轨道支架22转动180度的两种状态。
如图1和2所示，所述滑轨23与所述轨道支架22转动连接；通过所述滑轨23相对所述轨道支架22转动，所述滑轨23的移动轨迹包围载物台21。
需要指出的是，环状结构包括：圆环、方环、规则或不规则边长的多边形环等。
作为另一种示例，滑轨23也可为至少两个曲状结构，如半圆环形、“U”型、“凹”字型等。
该实施例中，滑轨23转动过程中，相对于所述轨道支架22转动180度的两种状态，使滑轨23的移动轨迹能够将载物台21包围。这样，结合天线3在滑轨23上滑动，可以使天线3的发射具有包围载物台21的全方位的发射角度，由于天线可调整的发射角度覆盖载物台，这样有利于提高天线与待充电设备5的充电匹配程度，并调整天线3至充电效率较高的发射位置。
具体的，如图1和2所示，所述轨道支架22包括：第一支撑臂221和第二支撑臂222；所述第一支撑臂221与所述滑轨23的第一位置转动连接，所述第二支撑臂222通过第一电机223与所述滑轨23的第二位置转动连接，所述第一电机223与所述控制单元电连接；所述第一位置与所述第二位置处于所述环状结构的同一径向轴线上；所述装置还包括：载物台21，所述载物台21通过连接轴224与所述第一支撑臂221固定连接，所述滑轨23的第一位置穿过所述连接轴224；所述滑轨23相对所述轨道支架22转动时，所述载物台21置于所述环状结构内。
其中，该滑轨23可以为两个半圆环结构，或也可以为至少一个完整圆环结构。
需要指出的是，环状导轨23穿过第一支撑臂221与载物台21的连接轴224，不影响导轨23的转动。
该实施例中，第一电机223连接环状结构的滑轨23，并驱动滑轨23沿着第一电机223延长轴线进行至少为180°的转动，以实现滑轨23覆盖为完整球面，滑轨23上装有发射天线3，发射天线3可以沿着滑轨23移动和悬停，从而实现发射天线3的移动范围基本覆盖整个球面，能够提高待充电设备5摆放的灵活度。
在一实施例中，所述滑轨23与所述轨道支架22滑动连接；通过所述滑轨23相对所述轨道支架22移动，所述滑轨23的移动范围覆盖所述载物台21。
该实施例中，滑轨23可以为框架结构或曲状结构，如倒“U型”的两个底角与轨道支架22滑动连接；或者，可以为由框架结构组成。
在一实施例中，所述轨道支架22包括导轨结构，所述滑轨23通过所述导轨结构与所述轨道支架22滑动连接；所述第一状态和所述第二状态分别为所述滑轨23处于所述导轨结构的起始端和结束端的两种状态；其中，所述天线3沿所述滑轨23的滑动方向与所述滑轨23沿所述导轨结构的滑动方向互相垂直。
该实施例中，滑轨23的移动方向，与滑块23沿着滑轨23的移动方向是互相垂直的，两个互相垂直方向的独立移动叠加为滑块23在对应平面的多位置移动，从而实现与滑块24连接的发射天线3的多位置移动，能够提高待充电设备5摆放的灵活度。
具体的，在一实施例中，如图3至6所示，无线充电装置还包括：载物台21；所述轨道支架22包括：多个框架结构225，所述底座1和多个所述框架结构225围设所述载物台21形成充电空间；每个所述框架结构225上设有所述导轨结构，所述导轨结构滑动连接有至少一个所述滑轨23。

该实施例中，通过天线支架33与转动支架32转动连接，转动支架32与滑块24转动连接，实现通过两个相互独立的转动角度，叠加实现天线的多个角度转动，以增加天线活动的灵活性。
在一具体实施例中，参见图11，所述滑块24设置有开槽，所述转动支架32置于所述开槽中；所述转动支架32为四边形的环状结构，所述转动支架32的其中两个对角分别通过第一转动结构与所述滑块24连接；所述转动支架32的另两个对角分别通过第二转动结构与所述天线支架33连接；所述转动支架32相邻的两个侧面上分别设置有第一磁块321和第二磁块322；所述滑块24在相对所述第一磁块321的位置设置有第一线圈244，在相对所述第二磁块322的位置设置有第二线圈245；所述第一线圈244和所述第二线圈245与控制单元电连接。

在一具体实施例中，所述第一转动结构包括：第一弹片323和第一滚珠324；所述第一弹片323与所述天线支架33固定连接，所述第一弹片323通过所述第一滚珠324与所述滑块24转动连接；所述第二转动结构包括：第二 弹片325和第二滚珠326；所述第二弹片325与所述转动支架32固定连接，所述第二弹片325通过所述第二滚珠326与所述天线支架33转动连接。

参见图2和图6所示，将手机、耳机等待充电设备5放入该无线充电装置，开启无线充电模式。无线充电装置中的位置检测单元，将各个待充电设备5的位置信息反馈给控制单元。控制单元通过滑轨23的移动，及滑块24在滑轨23上的移动，将发射天线移动到靠近待充电设备5的位置。N个发射天线会尝试与各个待充电设备5进行配对连接。在配对成功的组合中，控制单元选择配对成功且能量传输效率最高的天线组合，为待充电设备5进行充电。
需要指出的是，图2所示场景中，2个发射天线3都在载物台21的同一侧，同样也可以根据待充电设备5的摆放姿态，移动发射天线3到载物台21的两侧，以改善发射天线3与待充电设备5的接收天线之间的能量传输效率。如此，能够最小程度限制移动终端的摆放姿态，且保证高效的能量传输。

而待充电设备5可以包括接收天线501、整流转换电路502和负载503，接收天线501可以接收上述天线发射的能量，并通过整流转换电路502将上述能量转换为电能，再流向负载503，而负载503可以被称作为电池，从而达到给待充电设备5的电池进行无线充电的效果。
