电子手写笔300的无线充电线圈140与无线键盘100的无线充电线圈340耦合。电子手写笔300收纳至无线键盘100的收纳腔101内后，无线充电线圈(即Rx线圈)340开始工作。无线充电线圈(即Rx线圈)340感应无线充电线圈(即Tx线圈)140发出的交变电磁场，可以产生交变电信号，并向无线充电控制模块330输入该交变电信号。无线充电控制模块330可以将该交变电信号整流成直流电信号，并向充电控制 模块320输入该直流电信号。充电控制模块320可以根据该直流电信号为电池310充电。
其中，上述无线充电控制模块130和无线充电控制模块330可以包括匹配电路。该匹配电路可以包括电容组合。无线充电控制模块130中的匹配电路用于与无线充电线圈140形成LC谐振，以提升无线充电线圈140的发射效率。无线充电控制模块330中的匹配电路用于与无线充电线圈340形成LC谐振，以提升无线充电线圈340的接收效率。
当然，上述无线键盘100也可以通过无线充电线圈140接收其他设备的无线充电输入，即无线键盘100支持正向无线充电。无线键盘100的正向无线充电原理，可以参考无线键盘100为电子手写笔300无线充电过程中，电子手写笔300的无线充电原理。
无线键盘100也可以支持有线充电。例如，当连接了电源的电源适配器160(即有线充电器)连接充电接口150时，充电接口216上有充电输入。充电控制模块120连接充电接口150，用于接收由电源适配器160通过充电接口150的充电输入，为电池110充电。例如，该充电接口150可以是USB接口。

需要说明的是，上述匹配电路可以集成在充电管理模块640中，该匹配电路也可以独立于充电管理模块640，本申请实施例对此不作限制。图6以匹配电路可以集成在充电管理模块640中为例，示出无线键盘的硬件结构示意图。

以下实施例中提供的无线键盘的均可以包括上述硬件结构。本申请实施例这里详细介绍本申请实施例提供的无线键盘。
本申请实施例提供一种无线键盘100。如图1、图7或图11所示，该无线键盘100包括：键盘主体A、用于放置平板电脑200的支架B，以及用于活动连接键盘主体A和支架B的连接部C。
其中，连接部C包括一端设有开口102的收纳腔101。该收纳腔101用于经由开口102收纳图2所示的电子手写笔300。
在一些实施例中，如图1或图7上述连接部C可以包括柔性连接件C-1和收纳部件C-2。如图1或图7所示，柔性连接件C-1用于弯折以活动连接键盘主体A和支架B。例如，该柔性连接件C-1可以是柔性可折叠材料。
如图1或图7所示，收纳部件C-2固定在柔性连接件C-1的弯折区域。该收纳部件C-2内部中空，且收纳部件C-1的一端设有开口102，可形成收纳腔101。该收纳部件C-2的内壁(即收纳腔101)的形状与电子手写笔300的笔身的形状类似。例如， 该收纳部件C-2的内壁可以是圆柱体或者多棱柱体等任一种形状。该收纳部件C-2可以是塑料材质。
示例性的，图8为图7所示的无线键盘100的键盘主体A和支架B合并，且电子手写笔300未插入收纳腔101之前，无线键盘100的立体图。图9为图7所示的无线键盘100的键盘主体A和支架B合并，且电子手写笔300经由开口102还未完全插入收纳腔101时，无线键盘100的立体图。图9为图7所示的无线键盘100的键盘主体A和支架B合并，且电子手写笔300经由开口102插入收纳腔101后，无线键盘100的立体图。
应注意，与图2和图4不同的是，图8、图9和图10所示的无线键盘100中没有固定或安装平板电脑200。
在另一些实施例中，如图11所示，上述连接部C包括转轴C-3用于活动连接键盘主体A和支架B。如图11所示，转轴C-3的内部中空，且转轴C-3的一端设有开口102，可形成收纳腔101。
上述任一实施例所述的上述收纳腔101内设置有无线充电线圈140。如图1、图7或图11所示，上述键盘主体A中设置有充电接口150。该键盘主体A还包括无线充电控制模块130。如图5所示，无线充电控制模块130连接充电接口150，且无线充电控制模块130连接无线充电线圈140。例如，无线键盘100可以包括无线充电控制芯片(如Tx芯片)。该无线充电控制模块130可以集成在无线充电控制芯片(如Tx芯片)中实现。
上述充电接口150，用于接收直流电信号，如5V的直流电信号。例如，该充电接口150可以是Type-C接口、Micro B接口或者POGO pin接口中的任一种。当然，本申请实施例中的充电接口150包括但不限于上述Type-C接口、Micro B接口或者POGO pin接口，该充电接口150还可以是其他可以提供直流电信号的接口，本申请实施例对此不作限制。
上述无线充电控制模块130，用于若检测到充电接口150输入直流电信号，则将直流电信号转换为交流电信号，并向无线充电线圈140传输该交流电信号。
上述无线充电线圈140，用于响应于交流电信号产生交变电磁场，为收纳在收纳腔101内的电子手写笔300无线充电。
具体的，无线键盘100的无线充电控制模块130可检测到充电接口150输入直流电信号。一般而言，充电接口150可以包括电源线、数据线(也称为信号线)和接地线。例如，以上述充电接口150是USB接口为例。USB接口可以包括四条线：电源正极线(如红色的线)、正电压数据线(如白色的线)、负电压数据线(如绿色的线)和接地线(如黑色的线)。
其中，充电接口150的电源线连接充电控制模块120和无线充电控制模块130，充电接口150的数据线也可以连接充电控制模块120和无线充电控制模块130。因此，当充电接口150输入直流电信号(即有充电输入)时，无线充电控制模块130可以检测到该直流电信号(即充电输入)。
在另一些实施例中，可以由无线键盘100的处理器检测到充电接口150输入直流电信号。在该实施例中，充电接口150的电源线连接充电控制模块120和无线充电控 制模块130，充电接口150的数据线连接处理器。因此，当充电接口150输入直流电信号(即有充电输入)时，处理器可以检测到该直流电信号(即充电输入)。
本申请实施例中，当无线键盘100的电源适配器160连接电源，并连接充电接口150时，电源适配器则可以向充电接口150输入直流电信号。具体的，电源适配器160连接电源，并连接充电接口150后，可以将来自电源的高压交流电(如220V交流电)转换成低压直流电(如5V直流电)。电源适配器160通过充电接口150向无线键盘100输入直流电信号，如5V的直流电信号。该直流电信号通过充电接口150输入无线键盘100之后，可以供无线键盘100有线充电或者反向无线充电。
综上所述，本申请实施例提供的无线键盘100不仅具有电子手写笔300的收纳功能，还可以为电子手写笔300无线充电。
在上述实施例中，由充电接口150输入的直流电信号提供用于进行反向无线充电的能量源。在另一些实施例中，还可以由无线键盘100的电池110提供用于进行反向无线充电的能量源。
在该实施例中，无线充电控制模块130可以在检测到电子手写笔300收纳至收纳腔101内(即入盒)，通过充电控制模块120接收来自电池110的直流电信号，并将该直流电信号转换为交流电信号。如此，无线充电线圈140便可以响应于交流电信号产生交变电磁场，为收纳在收纳腔101内的电子手写笔300无线充电。
当然，无线充电控制模块130也可以在检测到电子手写笔300从收纳腔101被取出(即出盒)时，停止接收来自电池110的直流电信号。或者，可以由无线键盘100的处理器对电子手写笔300进行出盒和入盒检测，然后将检测结果通知给无线充电控制模块130；或者，由处理器根据检测结果指示无线充电控制模块130执行相应的事件。
本申请实施例中，电子手写笔300的出盒和入盒检测的方法可以参考常规技术中的出盒和入盒检测方法，如常规技术中TWS耳机的出盒和入盒检测方法；本申请实施例这里不予赘述。
在该实施例中，无论充电接口150有没有充电输入，即无论充电接口150有没有输入直流电信号，无线键盘100都可以由电池110提供能量源，为收纳在收纳腔101内的电子手写笔300无线充电。
可以理解，如果由电池110提供用于进行电芯预热的能量源；那么，在为电池110充电之前，则会先消耗电池110的电量。电池110的充放电次数越多，对电池110的损耗越大，影响电池110的使用寿命。
并且，在充电接口150输入直流电信号(即充电接口150有充电输入)的情况下，该直流电信号是可以为电池110充电的。如此，为电池110充电的过程中，则可能会出现电池110的电量先减少再增多的现象，容易造成用户不必要的误解，使用户误以为电池110故障。
综上所述，本申请实施例中，由充电接口150输入的直流电信号提供用于进行电芯预热的能量源，可以避免用户误以为电池110故障，还可以减少对电池110不必要的损耗，延长电池110的使用寿命。
另一些实施例中，充电接口150提供的直流电信号的电压值与无线充电控制模块 130的工作电压值可能不同。例如，无线充电控制模块130的工作电压值可能为5.5V，而充电接口150提供的直流电信号的电压值可能会5V。或者，充电接口150提供的直流电信号的电压值可能不稳定。如此，则可能会影响无线充电控制模块130的正常工作。
基于这种情况，如图12所示，上述无线键盘100还可以包括稳压模块1201。上述无线充电控制模块130连接充电接口150，具体可以为：无线充电控制模块130通过稳压模块1201连接充电接口150。
稳压模块1201，用于将来自充电接口150的直流电信号的电压转换为无线充电控制模块130的工作电压。
本申请实施例中，可以由稳压模块1201将充电接口150所提供的直流电信号的电压转换为无线充电控制模块130的工作电压。这样，可以保证无线充电控制模块130的正常工作。
在另一些实施例中，上述收纳腔内还设置有弹压器件。当电子手写笔300收纳在收纳腔101内时，该弹压器件与电子手写笔300的第一端301接触。如图2所示，该第一端301是电子手写笔300收纳在收纳腔101内时，位于开口120的一端。
该弹压器件，用于响应于用户对收纳在收纳腔101内的电子手写笔300的第二端302的按压操作，将电子手写笔300由第二端302向第一端301的方向弹出收纳腔101。该第二端302与第一端301相对。上述弹压器件有助于用户将电子手写笔300从无线键盘100的收纳腔101中取出。
本申请实施例还提供一种计算机存储介质，该计算机存储介质包括计算机指令，当所述计算机指令在上述无线键盘上运行时，使得该无线键盘执行上述实施例中无线键盘100执行的各个功能或者步骤。
本申请实施例还提供一种计算机程序产品，当所述计算机程序产品在计算机上运行时，使得所述计算机执行上述实施例中无线键盘执行的各个功能或者步骤。

所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是一个物理单元或多个物理单元，即可以位于一个地方，或者也可以分布到多个不同地方。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外，在本申请各个实施例中的各功能单元可以集成在一个处理单元中，也可以 是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
