为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开具体实施例及相应的附图对本公开技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动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。
以下结合附图，详细说明本公开各个实施例公开的技术方案。
如图1-图3所示，本公开实施例公开一种无线充电器，该无线充电器可以实现移动终端100的无线充电，该移动终端100内设有接收线圈110。本公开实施例所公开的移动终端100可以为智能手机、平板电脑、电子书阅读器或可穿戴设备。该移动终端100也可以是其他设备，本公开实施例对此不做限制。
无线充电器具体可以包括壳体200、驱动机构500、发射线圈600和电路板300，其中，驱动机构500、发射线圈600和电路板300均设置于壳体200内。
壳体200是上述无线充电器的各个零部件的安装基础，电路板300与发射线圈600电连接，从而为发射线圈600提供电能，发射线圈600通电时产生磁场，移动终端100中的接收线圈110位于磁场内时，可以在接收线圈110内产生电流，从而为移动终端100充电。具体实施例中，壳体200可以包括第一盖体210和第二盖体220，第一盖体210和第二盖体220可拆卸连接，以便组装及维护无线充电器。具体地，第一盖体210和第二盖体220可以采用螺纹连接或卡接等方式连接在一起。为了使该无线充电器的组装以及维修更加方便，可以采用结构简单、拆卸方便的卡接方式将第一盖体210和第二盖体220连接在一起。驱动机构500、发射线圈600和电路板300可以安装在第一盖体210上，也可以安装在第二盖体220上。发射线圈600与驱动机构500设置于第一盖体210上时，需要将第一盖体210反向放置才能进行维修操作，使得操作步骤复杂。一种可选的实施例中，发射线圈600与驱动机构500设置于第二盖体220上，将第一盖体210拆卸后，无线充电器内部的 部件裸露在外，可以直接进行维修操作，维修操作简单。由于移动终端100通常放置在第一盖体210上，因此发射线圈600所产生的磁场需要穿过第一盖体210后覆盖接收线圈110，因此第一盖体210可以采用塑胶或者玻璃等磁场辐射性能较好的材料。第二盖体220的材料没有特殊要求，一般可以采用成本较低的塑料等材料，以此降低制造成本。
本公开实施例中，发射线圈600可活动地设置于壳体200内，因此发射线圈600可以相对于壳体200运动。驱动机构500与发射线圈600连接，以驱动发射线圈600在壳体200内运动。发射线圈600的运动形式可以是转动，也可以是移动，也可以是移动和转动的复合形式。具体地，可以在壳体200内设置导向槽，该导向槽可以是直线结构也可以是环形结构，发射线圈600安装在导向槽上，使得发射线圈600可以沿着导向槽的延伸路径运动。该发射线圈600的形状可以是矩形、椭圆形、圆形或者其他形状，本公开实施例对此不做限制。
本公开实施例公开的无线充电器中，壳体200内设有可活动的发射线圈600，驱动机构500可以驱动发射线圈600在壳体200内运动，当发射线圈600运动到一个与接收线圈110相对耦合面积较大的位置时，接收线圈110内产生的电流更大，为移动终端100提供的电能更多，因此无线充电器的充电效率更高。
前文提到，可以在壳体200内加工导向槽，以实现发射线圈600运动时的导向，此时壳体200的壁厚需要增大，使得无线充电器的重量增加，携带不方便。为了解决该问题，可以在壳体200内安装导轨400，该导轨400的材质可以是金属材质也可以是塑料材质或者其他材质。发射线圈600与导轨400滑动连接，因此发射线圈600可以在导轨400上运动。具体实施例中，导轨400可以通过螺栓等紧固件安装在壳体200上。
一种可选的实施例中，导轨400可选用直线型导轨，使得发射线圈600在壳体200内的运动形式为移动。此种运动方式一方面可以满足各种移动终端100内的接收线圈110的位置变化，还可以简化发射线圈600的运动形式，使得发射线圈600的控制更加方便。可选地，驱动机构500可以包括驱动源510和丝杆520。驱动源510具体可选用驱动电机，或者其他可以输出动力的 结构。丝杆520与导轨400相互平行，驱动源510和丝杆520连接，丝杆520与发射线圈600连接，以带动发射线圈600在壳体200内移动。具体实施例中，发射线圈600上可以固定若干螺母，丝杆520的一端与螺母配合，丝杆520的另一端与驱动源510相连接，当驱动源510驱动丝杆520转动时，丝杆520带动螺母移动，螺母即可带动发射线圈600在导轨400上做直线运动。
上述驱动机构500的工作状态将会影响发射线圈600的运动行程，因此可以在壳体200内增加额外的控制结构，以实现对驱动机构500的控制，例如，可以在壳体200内设置控制器，该控制器与驱动源510连接，控制器能够检测无线充电器对移动终端100进行充电时的充电效率，同时根据该充电效率控制发射线圈600的移动位置。相对于用户通过对移动终端100充电快慢的观察，手动调节发射线圈600的位置的充电方式来说，此方案能够更加精确的确定发射线圈600与接收线圈110的耦合面积较大的位置，进一步提高无线充电器的充电效率。
进一步地，为提高无线充电器内部结构的紧凑性，减小这些结构的安装空间，可以将控制器集成在电路板300上。这里的电路板300可以为印刷电路板或柔性电路板，或者为软硬结合板，还可以采用其他结构形式，本文对此不做限制。
进一步地，为了降低产品的制造成本，发射线圈600的形状可以为圆形。具体地，发射线圈600可采用加工方便且成本相对较低的铜丝制成。为了使发射线圈600移动时不发生偏斜，在垂直于发射线圈600的方向上，发射线圈600的圆心的投影位于丝杆520的投影和导轨400的投影之间，使得发射线圈600更加稳定。
一种实施例中，为了进一步确保发射线圈600和接收线圈110的耦合面积相对较大，可以对用户在无线充电器上放置移动终端100的方位进行限定。壳体200包括条形部201，条形部201的延伸方向与发射线圈600的移动方向互相平行。具体地，这里的条形部201可以为定位结构。用户为了使移动终端100放置平稳，移动终端100的长边会沿着条形部201延伸的方向放置。而条形部201延伸的方向又与发射线圈600的移动方向保持一致，因此发射线圈600移动时更容易找到耦合面积较大的位置。由此可见，壳体200的条 形部201起到了限定移动终端100放置方位的作用。
进一步地，为了提升产品外观质感，壳体200还包括第一弧形部202和第二弧形部203，第一弧形部202和第二弧形部203设置于条形部201的两端，条形部201、第一弧形部202和第二弧形部203共同围成安装空间，发射线圈600、驱动机构500和导轨400均位于该安装空间内。第一弧形部202和第二弧形部203在与条形部201的接口位置平滑连接没有棱边，使得整个壳体更加美观，提高了用户体验。
当壳体200包括第一盖体210和第二盖体220时，条形部201、第一弧形部202和第二弧形部203的一部分属于第一盖体210，另一部分属于第二盖体220。进一步地，当第一盖体210和第二盖体220卡接时，考虑到在曲面上加工卡勾的加工难度较大，所以在条形部201中分别属于第一盖体210和第二盖体220的部分上设置卡勾，以使第一盖体210和第二盖体220的卡勾一一对应地相互卡接。
基于上述任一实施例公开的无线充电器，本公开还公开一种无线充电器的控制方法，该控制方法用于实现上述任一实施例所述的无线充电器的控制，该控制方法包括：
S110、控制驱动机构500带动发射线圈600运动；
即向驱动机构500发送控制信号，使得驱动机构500启动，并带动发射线圈600沿预定轨迹运动。
S120、检测发射线圈600与接收线圈110在当前位置的充电效率并记录最大充电效率所对应的发射线圈位置；
在发射线圈600的预定轨迹中，可以设置多个检测点，当发射线圈600运动至对应的检测点时，检测发射线圈600在该检测点处时，发射线圈600与接收线圈110之间的充电效率。同时，发射线圈600在该检测点时所处的位置就是发射线圈位置，该发射线圈位置与对应的充电效率同时记录下来，从而得到多个发射线圈位置与多个充电效率之间的对应关系表。
S130、比较所记录的多个所述充电效率，多个所述充电效率中的最大值为最大充电效率；
如上所述，发射线圈600在多个检测点处所对应的充电效率被记录下来， 通过对这些数据进行分析处理，可以得出发射线圈600运动时所经过的多个检测点中，哪一个检测点处的充电效率最大，该最大值就是最大充电效率。并且，根据多个发射线圈位置与多个充电效率之间的对应关系表，可以得到最大充电效率所对应的发射线圈位置。需要说明的是，检测点的数量会对整个控制过程的精度产生影响，同时也会影响控制过程的执行效率，因此该检测点的数量可以根据实际情况合理设置。
S140、控制驱动机构500将发射线圈600带动至最大充电效率所对应的发射线圈位置处。
步骤S130中已经得到了最大充电效率及其对应的发射线圈位置，之后便可以控制驱动机构500将发射线圈600带动至该最大充电效率所对应的发射线圈位置处，使得发射线圈600与接收线圈110在该位置处相互作用，从而提高充电效率。
可选的，步骤S140之后还包括：
S150、检测接收线圈110与发射线圈600的相对位置是否发生变化，如果是，返回步骤S110，如果否，则不进行任何操作。
在充电的过程中，接收线圈110与发射线圈600的相对位置发生变化，会影响充电效率。检测接收线圈110与发射线圈600的相对位置是否发生变化，如果是，则返回步骤S110，重新找寻最大充电效率所对应的发射线圈位置，并且驱动机构500将发射线圈600带动至新的最大充电效率所对应的发射线圈位置处，从而提高充电效率。此种控制方法，能够实时对接收线圈110和发射线圈600的充电效率做出调整，从而使得无线充电器更加智能化。
本公开上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本公开的实施例而已，并不用于限制本公开。对于本领域技术人员来说，本公开可以有各种更改和变化。凡在本公开的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本公开的权利要求范围之内。
