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。
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无线充电方法进行详细地说明。
如图1所示，本申请提供一种实施例的可折叠的电子设备，电子设备包括：第一主体101、第二主体102和充电线圈，充电线圈包括：第一线圈1031、第二线圈1032和第三线圈1033。
第一线圈1031设置于电子设备的第一主体101内，第二线圈1032设置 于电子设备的第一主体101的第一侧，与第一线圈1031间隔设置，第三线圈1033设置于电子设备的第二主体102的第一侧；
其中，在电子设备未折叠的情况下，第一主体101的第一侧与第二主体102的第一侧贴合；在电子设备的折叠角度大于或等于预设角度的情况下，第二线圈1032和第三线圈1033共同工作以进行充电，在电子设备的折叠角度小于预设角度的情况下，第一线圈1031工作以进行充电。
需要说明的是，上述电子设备未折叠可以理解为电子设备完全展开，此时电子设备的折叠角度为180°。在电子设备未折叠的情况下，第一主体101的第一侧与第二主体102的第一侧贴合，第二线圈1032是设置于第一主体101的第一侧，第三线圈1033是设置于第二主体102的第一侧，从而在电子设备未折叠的情况下，即电子设备的折叠角度为180°的情况下，第一主体101的第一侧与第二主体102的第一侧贴合。
需要理解的是，电子设备的折叠角度为两个主体设置有屏幕的一面之间的夹角，而预设角度可以为预先根据经验设置的一个角度，例如，可预先根据电子设备的屏幕尺寸大小、电子设备的第一屏幕1011和第二屏幕1021的屏幕尺寸占比等信息来设置。在电子设备的折叠角度小于预设角度的情况下，表示折叠显示屏展开角度较小，即电子设备趋近于折叠状态，可利用第一线圈1031为电子设备充电，第一无线充电线圈感应发射线圈产生的变化的磁场产生电压，为电子设备充电。在电子设备的折叠角度大于或等于预设角度的情况下，表示折叠显示屏展开角度较大，即电子设备趋近于展开状态，可利用第二线圈1032和第三线圈1033共同工作为电子设备充电，第二线圈1032和第三线圈1033感应发射座中发射线圈产生的变化的磁场，产生电压，为电子设备充电。
在本申请实施例的可折叠的电子设备，设置有第一线圈1031、第二线圈1032和第三线圈1033，在电子设备中，若折叠角度大于或等于预设角度，第二线圈1032和第三线圈1033共同工作以进行充电，若折叠角度小于预设角度，第一线圈1031工作以进行充电。即在电子设备中设置第一线圈1031、第二线圈1032和第三线圈1033，可根据电子设备的折叠状态采用对应的线圈进行工作，实现充电，即使电子设备的折叠角度可调整变化，但可根据电 子设备的折叠角度的大小，选择对应的线圈进行充电，不再是电子设备无论处于什么折叠状态均是通过同样的充电线圈充电，可提高充电效果。
在一个实施例中，第一线圈1031位于第一主体101的中心区域，在电子设备的折叠角度为180度的情况下，第二线圈1032和第三线圈1033组合形成的目标线圈位于第一主体101和第二主体102贴合形成的主体的中心区域。
如此，电子设备放置于充电座，通过第二线圈1032和第三线圈1033共同工作进行充电的情况下，若将第二线圈1032和第三线圈1033与充电座中的发射线圈相对，电子设备的重心位置可与充电座的中心区域相对，不会偏离中心区域，从而能较稳定地置于无线充电座中进行充电。
作为一个示例，在电子设备的折叠角度为180度的情况下，第二线圈1032和第三线圈1033组合形成的目标线圈为圆形线圈，这样，在完全展开的情况下，第二线圈1032和第三线圈1033能更好地感应发射线圈的磁场，提高感应效果，从而提高充电效率等。
在一个实施例中，目标线圈为柔性线圈，也即是目标线圈可随着电子设备的折叠弯曲而弯曲，此时目标线圈可以是一个完整的线圈，第二线圈和第三线圈可以看作该目标线圈的一部分，可减少因为目标线圈在电子设备折叠弯曲对目标线圈的损坏，提高目标线圈的使用寿命等。
如图2所示，本申请提供一种实施例的无线充电方法，由可折叠的电子设备执行，电子设备包括：第一主体、第二主体和充电线圈，充电线圈包括第一线圈、第二线圈和第三线圈；第一线圈设置于电子设备的第一主体内，第二线圈设置于电子设备的第一主体的第一侧，与第一线圈间隔设置，第三线圈设置于电子设备的第二主体的第一侧；在电子设备未折叠的情况下，第一主体的第一侧与第二主体的第一侧贴合；
其中，方法包括：
步骤210：获取电子设备的折叠角度。
电子设备为可折叠设备，通过转动第一主体和第二主体中的至少一项可折叠电子设备，可改变可折叠电子设备的折叠角度。折叠角度的范围为[0°，180°]，在折叠角度为0°的情况下，表示电子设备处于完全折叠状态，在折叠角度为180°的情况下，表示电子设备处于完全展开状态，即处于未折叠 状态。在折叠角度在0°到180°之间的情况下，表示电子设备处于部分展开状态或部分折叠状态。在本实施例的无线充电方法中，可先获取可折叠的电子设备的折叠角度。检测电子设备的折叠角度的方式有多种，在本实施例中不作限定。另外，可实时检测折叠角度，也可每间隔预设时长(例如，T，T＞0)检测折叠角度。
步骤220：在电子设备的折叠角度小于预设角度的情况下，控制第一线圈工作以进行充电。
预设角度为预先根据经验设置的一个角度，例如，可预先根据电子设备的屏幕尺寸大小、电子设备的电子设备的第一屏幕和第二屏幕的屏幕尺寸占比等信息来设置。在电子设备的折叠角度小于预设角度的情况下，表示折叠显示屏展开角度较小，可控制第一线圈工作为电子设备充电。作为一个示例，例如，可将第一线圈与电子设备的电池连通，第一线圈感应变化的磁场产生电压为电子设备的电池充电。
步骤230：在电子设备的折叠角度大于或等于预设角度的情况下，控制第二线圈和第三线圈共同工作以进行充电。
在电子设备的折叠角度大于或等于预设角度的情况下，表示折叠显示屏展开角度较大，可利用第二线圈和第三线圈共同工作为电子设备充电，通过第二线圈和第三线圈共同感应变化的磁场，产生电压，为电子设备充电。作为一个示例，例如，可将第二线圈和第三线圈与电子设备的电池连通，第二线圈和第三线圈共同工作感应变化的磁场产生电压为电子设备的电池充电。
在本实施例的无线充电方法中，电子设备中设置有第一线圈、第二线圈和第三线圈，可获取电子设备的折叠角度，在电子设备的折叠角度小于预设角度的情况下，第一线圈工作为电子设备充电，在电子设备的折叠角度大于或等于预设角度的情况下，通过第二线圈和第三线圈共同工作为电子设备充电。即使电子设备的折叠角度可调整变化，但可根据电子设备的折叠角度的大小，可选择对应的无线充电线圈进行充电，不再是电子设备无论处于什么折叠状态均是通过同样的充电线圈充电，可提高充电效果。
在一个实施例中，控制第一线圈工作以进行充电之后，或控制第二线圈和第三线圈共同工作以进行充电之后，方法还包括：
在电子设备处于充电状态的情况下，若检测到电子设备的折叠角度从第一角度变化到第二角度，控制候选线圈工作以进行充电，并输出提示信息，提示信息用于提示用户朝目标方向移动电子设备，使候选线圈与发射线圈对准；
其中，候选线圈包括第二线圈和第三线圈，或者候选线圈为第一线圈，目标方向为第二线圈指向第一线圈的方向，或者为第一线圈指向第二线圈的方向。
电子设备的折叠角度从第一角度变化到第二角度，表示电子设备此时的折叠角度为第二角度，在折叠角度有变化的时候，可输出提示信息，以提示用户移动电子设备，用户可根据提示信息移动电子设备，使候选线圈靠近无线充电座的发射线圈产生的变化的磁场中，与发射线圈对准，使电子设备的候选线圈能更有效地感应变化的磁场，为电子设备充电，提高无线充电效率。
需要说明的是，若是控制第一线圈工作以进行充电之后，检测到电子设备的折叠角度从第一角度变化到第二角度，则候选线圈包括第二线圈和第三线圈，目标方向为第二线圈指向第一线圈的方向，若是控制第二线圈和第三线圈共同工作以进行充电之后，检测到电子设备的折叠角度从第一角度变化到第二角度，则候选线圈包括第一线圈，目标方向为第一线圈指向第二线圈的方向。
在一个实施例中，在第一角度小于预设角度以及第二角度大于或等于预设角度的情况下，输出提示信息，其中，目标方向为第二线圈指向第一线圈的方向；或者，
在第一角度大于或等于预设角度以及第二角度小于预设角度的情况下，输出提示信息，其中，目标方向为第一线圈指向第二线圈的方向。
电子设备的折叠角度从第一角度变化到第二角度，表示电子设备此时的折叠角度为第二角度，若第一角度小于预设角度以及第二角度大于或等于预设角度，表示电子设备从一个相对折叠的状态变换到一个相对展开的状态，此时，可输出用于提示用户朝第二线圈指向第一线圈的目标方向移动电子设备的提示信息，以提示用户朝第二线圈指向第一线圈的目标方向移动电子设备，用户可移动电子设备，使第二线圈和第三线圈形成的目标线圈靠近无线 充电座的发射线圈产生的变化的磁场中，与发射线圈对准，使电子设备的第二线圈和第三线圈更有效地共同工作以对电子设备充电，提高充电效率。
若第一角度大于或等于预设角度以及第二角度小于预设角度，表示电子设备从一个相对展开的状态变换到一个相对折叠的状态，此时，可输出用于提示用户朝第一线圈指向第二线圈的目标方向移动电子设备的提示信息，以提示用户朝第一线圈指向第二线圈的目标方向移动电子设备，用户可移动电子设备，使第一线圈靠近无线充电座的发射线圈产生的变化的磁场中，与发射线圈对准，使电子设备的第一线圈更有效地工作以对电子设备充电，提高无线充电效率。
作为一个示例，提示信息可以包括提示图，提示图中包括模拟的电子设备的电子设备当前的结构图、模拟的第一线圈、模拟的第二线圈和第三线圈、以及目标方向，用户可通过查看提示图中的内容，可按照目标方向移动电子设备，使电子设备的候选线圈更有效地工作为电子设备充电，提高充电效果。
在一个实施例中，输出提示信息，包括：
在第一接收功率与第二接收功率之间的功率差大于或等于预设阈值的情况下，输出提示信息；
其中，第一接收功率为折叠角度为第一角度时，电子设备的无线充电接收功率，第二接收功率为折叠角度为第二角度时，电子设备的无线充电接收功率。
即在本实施例中，除了第一角度和第二角度需要满足上述要求，而且接收功率需要满足要求，即在电子设备处于充电状态、检测到电子设备的折叠角度从第一角度变化到第二角度的情况下，若第一接收功率与第二接收功率之间的功率差大于或等于预设阈值，方可输出提示信息，提示用户移动电子设备，使电子设备通过对应的线圈更有效地为电子设备充电，而且可减少无线充电线圈充电的切换频率，提高充电效率。
需要说明的是，若第一角度小于预设角度以及第二角度大于或等于预设角度，上述预设阈值可以为第一预设阈值，若第一角度大于或等于预设角度以及第二角度小于预设角度，上述预设阈值可以为第二预设阈值，第一预设阈值与第二预设阈值可以不同。
下面以一个具体实施例对上述无线充电方法的过程加以具体说明，以可折叠的电子设备为移动终端为例进行说明，例如手机，手机为可折叠手机。
如图3和4所示，可折叠的电子设备包括第一主体101、第一主体101和充电线圈103，充电线圈103包括：第一线圈1031、第二线圈1032和第三线圈1033；第一线圈1031设置于电子设备的第一主体101内，第二线圈1032设置于电子设备的第一主体101的第一侧，与第一线圈1031间隔设置，设置于电子设备的第二主体102的第一侧。
第一主体101设置第一屏幕1011，第二主体102设置相背的第二屏幕1021和第三屏幕1022，第一屏幕1011和第二屏幕1021形成电子设备的可折叠的正面主屏幕，沿中间转轴可折叠，手机正面主屏幕全展开如图3所示。正面主屏幕的中间部分为可折叠柔性屏幕。可折叠手机可横向或竖向放置，从而，其显示屏可横屏或竖屏。
如图5所示，手机在完全折叠状态下结构示意图，其中，第一主体内部的第一线圈可位于第一主体的中心区域。手机完全折叠状态时，第一屏幕1011和第二屏幕1021完全折叠，可通过第三屏幕1022显示内容，第三屏幕1022为设置于手机背面的屏幕，而第二线圈和第三线圈的空间位置，在折叠后在垂直于屏幕方向上重叠。
如图6所示，为本实施例中无线充电方法的流程示意图，具体步骤如下：
步骤601：可折叠手机放入无线充电座上。
其中，无线充电座发射座可以是竖立或水平放置。
步骤602：确定初始进行无线充电的接收线圈。
例如，可折叠手机检测初始放入无线充电座的电子设备的折叠角度，确定初始进行无线充电的接收线圈：
(1)手机的折叠程度用第一屏幕和第二屏幕之间的折叠角度β来表征，其中，β角度越大展开程度越大；
手机完全折叠时，β＝0°；
手机完全展开时，β＝180°；
手机部分展开或部分折叠时，0°<β<180°。
(2)比较折叠角度β与预设角度α，选择初始进行无线充电的接收线圈：
β＜α时：选择第一主体内的第一线圈作为接收线圈，即可将电子设备的第一主体正对无线充电座的发射线圈，通过第一线圈进行无线充电，即进行无线充电的检测和功率传输；
β≥α时：选择由两段线圈组成的第二线圈和第三线圈共同作为接收线圈，即可将电子设备的第二线圈和第三线圈形成的目标线圈正对无线充电座的发射线圈，通过第二线圈和第三线圈共同进行无线充电。
步骤603：手机检测折叠角度；
例如，可每间隔预设时长T进行折叠角度的检测。
步骤604：判断折叠角度是否大于或等于预设角度α：
(1)经过预设时长T，用户可能对屏幕进行动态来回折叠改变了折叠程度，若用户操作折叠屏起始状态的折叠角度为第一角度β1，折叠操作后结束状态的折叠角度为第二角度β2；
(2)若满足β1<α≤β2，即用户操作电子设备屏从一个相对折叠的状态，到一个相对展开的状态，并且结束状态时大于或等于预设角度α，进入步骤605；
(2)若满足β2<α≤β1，即用户操作折可叠显示屏从一个相对展开的状态，到一个相对折叠的状态，目标线圈有一个与无线充电座较大夹角分离开，并且结束状态时折叠角度β2小于预设阀值α，进入步骤606。
步骤605：判断折叠操作前后无线充电接收功率损耗是否大于第一预设阀值；
用户操作电子设备，在第一角度下对应的无线充电接收功率为第一接收功率P1，折叠操作后结束状态下第二角度对应的无线接收功率为第二接收功率P2，第一预设阈值为△P1，若P1-P2≥△P1，则需提醒用户要切换到第二无线充电线圈进行无线功率传输，进入步骤607；若P1-P2＜△P1，则说明功率损耗不大还不用切换，减少切换频次，进入步骤609。
步骤606：判断折叠操作前后无线功率损耗是否大于第二预设阀值；
在第一角度下对应的无线充电接收功率为第一接收功率P1，折叠操作后结束状态下第二角度对应的无线接收功率为第二接收功率P2，第二预设阈值为△P2，△P1和△P2都是描述折叠前后的功率损耗的阀值，区别在于值不同， 因折叠的或展开的功率不同，导致阀值不同。若P1-P2≥△P2，则需提醒用户要切换到第一无线充电线圈来进行无线功率传输，进入步骤608；若P1-P2＜△P2，则说明功率损耗不大还不用切换，进入步骤609。
步骤607：提示用户从第一线圈切换到的第二线圈和第三线圈共同工作进行无线充电；
例如，如图7所示，显示第一提示图，f1方向为第一移动提示方向，此时，目标方向即为第一移动提示方向，用户查看到第一提示图后，可按照f1方向的提示，移动手机，使手机通过第二线圈和第三线圈共同工作进行充电。
步骤608：提示用户从第二线圈和第三线圈共同工作切换到第一线圈进行无线充电；
例如，如图8所示，显示第二提示图，f2方向为第二移动提示方向，此时，目标方向即为第二移动提示方向，用户查看到第二提示图后，可按照f2方向的提示，移动手机，使手机通过第一线圈进行充电。
步骤609：判断手机是否还处在无线充电状态：
若是，则间隔时间T轮询到步骤603；
否则，不在充电状态，进入步骤610退出检测；
步骤610：退出检测。即退出折叠角度检测。
