图2A为本申请实施例提供的触控笔100的结构示意图。该触控笔100以主动式电容笔为例。参照图2A所示，触控笔100可以包括笔尖10、笔杆20和后盖30。笔杆20的内部为中空结构，笔尖10和后盖30分别位于笔杆20的两端，后盖30与笔杆20之间可以通过插接或者卡合方式，笔尖10与笔杆20之间的配合关系详见图2B的描述。
图2B为本申请实施例提供的触控笔的部分拆分结构示意图。参照图2B所示，触控笔100还包括主轴组件50，主轴组件50位于笔杆20内，且主轴组件50在笔杆20内可滑动 设置。主轴组件50上具有外螺纹51，笔尖10包括书写端11和连接端12，其中，笔尖10的连接端12具有与外螺纹51配合的内螺纹(未示出)。
当主轴组件50装配到笔杆20内时，笔尖10的连接端12伸入笔杆20内且与主轴组件50的外螺纹51螺纹连接。在一些其他示例中，笔尖10的连接端12与主轴组件50之间还可以通过卡合等可拆卸方式实现连接。通过笔尖10的连接端12与主轴组件50之间可拆卸相连，这样实现了对笔尖10的更换。
其中，为了对笔尖10的书写端11受到的压力进行检测，参照图2A所示，笔尖10与笔杆20之间具有间隙10a，这样可以确保笔尖10的书写端11受到外力时，笔尖10可以朝向笔杆20移动，笔尖10的移动会带动主轴组件50在笔杆20内移动。而对外力的检测，参照图2B所示，在主轴组件50上设有压感组件60，压感组件60的部分与笔杆20内的固定结构固定相连，压感组件60的部分与主轴组件50固定相连。这样，主轴组件50随着笔尖10移动时，由于压感组件60的部分与笔杆20内的固定结构固定相连，所以主轴组件50的移动会驱动压感组件60形变，压感组件60的形变传递给电路板70(例如，压感组件60与电路板70之间可以通过导线或者柔性电路板实现电连接)，电路板70根据压感组件60形变检测出笔尖10的书写端11的压力，从而根据笔尖10书写端11的压力控制书写端11的线条粗细。
需要说明的是，笔尖10的压力检测包括但不限于上述方法。例如，还可以通过在笔尖10的书写端11内设置压力传感器，由压力传感器检测笔尖10的压力。
本实施例中，参照图2B所示，触控笔100还包括多个电极，多个电极例如可以为第一发射电极41、接地电极43和第二发射电极42。第一发射电极41、接地电极43和第二发射电极42均与电路板70电连接。第一发射电极41可以位于笔尖10内且靠近书写端11，电路板70可以被配置为可以分别向第一发射电极41和第二发射电极42提供信号的控制板，第一发射电极41用于发射第一信号，当第一发射电极41靠近电子设备200的触控屏201时，第一发射电极41与电子设备200的触控屏201之间可以形成耦合电容，这样电子设备200可以接收到第一信号。其中，第二发射电极42用于发射第二信号，电子设备200根据接收到的第二信号可以判断触控笔100的倾斜角度。本申请实施例中，第二发射电极42可以位于笔杆20的内壁上。在一种示例中，第二发射电极42也可以位于主轴组件50上。
接地电极43可以位于第一发射电极41和第二发射电极42之间，或者，接地电极43可以位于第一发射电极41和第二发射电极42的外周围，接地电极43用于降低第一发射电极41和第二发射电极42相互之间的耦合。
当电子设备200接收来自触控笔100的第一信号时，触控屏201对应位置处的电容值会发生变化。据此，电子设备200可以基于触控屏201上的电容值的变化，确定触控笔100(或触控笔100的笔尖)在触控屏201上的位置。另外，电子设备200可以采用倾角检测算法中的双笔尖投影方法获取触控笔100的倾斜角度。其中，第一发射电极41和第二发射电极42在触控笔100中的位置不同，因此当电子设备200接收来自触控笔100的第一信号和第二信号时，触控屏201上两个位置处的电容值会发生变化。电子设备200可以根据第一发射电极41和第二发射电极42之间的距离，以及触控屏201上电容值发生变化的两个 位置处之间的距离，获取触控笔100的倾斜角度，更为详细的获取触控笔100的倾斜角度可以参照现有技术中双笔尖投影方法的相关描述。
本申请实施例中，参照图2B所示，触控笔100还包括：电池组件80，电池组件80用于向电路板70提供电源。其中，电池组件80可以包括锂离子电池，或者，电池组件80可以包括镍铬电池、碱性电池或镍氢电池等。在一种实施例中，电池组件80包括的电池可以为可充电电池或一次性电池，其中，当电池组件80包括的电池为可充电电池时，触控笔100可以通过无线充电方式对电池组件80中的电池进行充电。当然，也可通过有线充电方式对电池组件80中的电池进行充电，比如，在笔杆20靠近后盖30的一端设置电源连接器(图中未示出)，电源连接器与电池组件80连接。其后盖30可遮蔽电源连接器。
如图2C所示，触控笔100还可以包括：触摸传感器44。该触摸传感器44可以设置于笔杆20靠近笔尖10的区域。触摸传感器44可以用于检测作用于其上或附近的触摸操作。在一些实施例中，触摸传感器44可以包括区域441、区域442和区域443。在指定时间段1(例如，2秒)内，当触摸传感器44检测到作用于区域442上的长按操作并保持不变，且检测到触摸传感器上的触摸操作，该触摸操作的方向平行于笔杆20，触摸区域覆盖区域441和区域443时，触摸传感器44即确定出上述操作为滑动操作。例如，当触摸传感器44检测到作用于区域442上的长按操作并保持不变，且检测到触摸传感器上的触摸操作，该触摸操作的方向平行于笔杆20，且该触摸操作的移动位置由区域443至区域441时，触摸传感器44确定出上述操作为向上滑动操作(也可以被称为上滑操作)。当触摸传感器44检测到作用于区域442上的长按操作并保持不变，且检测到触摸传感器上的触摸操作，该触摸操作的方向平行于笔杆20，且该触摸操作的移动位置由区域441至区域443时，触摸传感器44确定出上述操作为向下滑动操作(也可以被称为下滑操作)。
响应于该滑动操作，触控笔100可以向电子设备200发送对应的功能信号，以使得电子设备200可以基于该功能信号执行相应的功能。
在一种可能的实现方式中，触控笔100还可以在指定时间段1(例如，2秒)内检测到触摸操作的方向平行于笔杆20，且触摸区域覆盖区域441和区域443时，确定出上述操作为滑动操作。本申请对此不作限制。其上滑操作和下滑操作中触摸操作移动位置的描述，可以参考前述说明，在此不再赘述。
如图3所示，当触控笔100为主动式电容笔时，电子设备200和触控笔100无线连接后，电子设备200可以通过触控屏201上集成的电极信号感应阵列向触控笔100发送上行信号。触控笔100可以通过接收电极接收该上行信号，且触控笔100通过发射电极(例如第一发射电极41和第二发射电极42)发射下行信号。下行信号包括上述的第一信号和第二信号。当触控笔100的笔尖10接触触控屏201时，触控屏201对应位置处的电容值会发生变化，电子设备200可以基于触控屏201上的电容值，确定触控笔100的笔尖10在触控屏201上的位置。在一种实施例中，上行信号和下行信号可以为方波信号。

其中，为了避免触控笔100放置于收纳部303中掉落，在一种实施例中，收纳部303的内壁上可以设置有磁性材料，触控笔100中可以设置磁性材料。触控笔100通过磁性材料之间的磁性吸附作用吸附在收纳部303内。当然，在一些示例中，触控笔100与收纳部303之间固定时，包括但不限于采用磁力吸附实现固定，例如，触控笔100与收纳部303之间还可以通过卡合方式实现固定。
其中，为了方便触控笔100从收纳部303中取出，收纳部303内可以设置弹出结构，例如，按压触控笔100的一端，弹出机构可以驱动触控笔100的一端从收纳部303向外弹出。

如图10所示，触控笔100中可以包括：触摸传感器44、处理器110和蓝牙模块180，电子设备200中可以包括：处理器210和无线接口260。应理解，图10中以蓝牙模块260表征无线接口260。在本申请另一些实施例中，触控笔100和电子设备200可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件，或软件和硬件的组合实现。图10中以及下述实施例中，以触控笔100和电子设备200的无线连接方式为蓝牙连接为例进行说明，触控笔100和电子设备200的无线连接方式还可以为其他类型的连接方式，可以参照上述实施例的相关描述。
处理器110可以基于蓝牙模块180，以及电子设备200中的蓝牙模块260，实现触控笔100和电子设备200的通信，如向电子设备200发送功能信号。
处理器210，用于基于蓝牙模块260接收来自触控笔100的功能信号，执行目标功能，具体可以参照下述实施例中的描述。
目前，当用户使用触控笔100针对电子设备200进行操作(例如，点触、书写和擦除笔迹等)时，需要使得触控笔100接触到电子设备200上的触摸屏。触控笔100可以和电子设备200基于电信号进行数据交互，同时，电子设备200可以根据触摸屏上电容值的变化，使得电子设备200响应于触控笔100发送的电信号执行相应的操作。然而，在一些应用场景(例如，投屏场景)中，触控笔100并不能远距离向电子设备200发送电信号以使其响应于该电信号执行指定操作(例如，翻页操作等)，因此操作十分不方便。
因此，本申请实施例提供了一种功能模式切换的方法。
触控笔100和电子设备200建立无线通信连接。触控笔100可以具有多种不同的功能模式。其中，该多种不同的功能模式中可以包括第一模式和第二模式。触控笔100可以在第一模式和第二模式之间进行切换。
在一种可能的实现方式中，触控笔100可以检测到用户作用于触控笔100上的指定切换操作1，响应于该指定切换操作1，触控笔100可以进行功能模式的切换(例如，从第一模式切换至第二模式，或，从第二模式切换至第一模式)。其中，该指定操作1可以是例如作用于触摸传感器44区域上的多次触摸操作(例如，连续触摸触控笔100上触摸传感器44区域三次)、长按触摸传感器44区域上的操作等。本申请对此不作限制。
在一种可能的实现方式中，触控笔100也可以检测到电子设备200发送的指定信号1(例如，前述中的上行信号)的强度。当检测到指定信号1的强度小于指定数值1(例如，-50dbm)时，触控笔100可以进行功能模式的切换(例如，从第一模式切换至第二模式)。当检测到指定信号1的强度大于指定数值1(例如，-50dbm)时，触控笔100也可以进行功能模式的切换(例如，从第二模式切换至第一模式)。示例性的，触控笔100中电极160可以接收到电子设备200上触摸屏中电极信号感应阵列202发送的上行信号的强度。当触控笔100检测到该上行信号的强度值小于-50dbm时，触控笔100可以从第一模式切换至第二模式。
在不同的功能模式下，当触控笔100接收到用户针对触控笔100的相同操作时，触控笔100可以对应有不同的功能信号。
示例性的，在第一模式中，输入1对应有功能信号1，该功能信号1对应有功能1。在第二模式中，输入1对应有功能信号5，该功能信号5对应有功能5。当触控笔100处于第一模式时，触控笔100可以和电子设备200中的触摸屏进行接触。触控笔100可以持续向电子设备200发送下行信号，以使得电子设备200检测触控笔100在电子设备200的触摸屏上的位置以及触控笔100的倾角。其中，该下行信号用于电子设备200执行书写功能和点触功能。当触控笔100接收到作用于触摸传感器44区域的输入1(例如，双击)时，触控笔100可以获取到第一模式下，输入1对应的功能信号1，继而将该功能信号1发送给电子设备200，使得电子设备200响应于该功能信号1，执行对应的功能1。
触控笔100可以检测到电子设备200中触摸屏发送的电信号(例如，前述中的上行信号)的强度。当触控笔100检测到该电信号的强度小于指定数值1(例如，-50dbm)时，触控笔100可以从第一模式切换至第二模式。
当触控笔100处于第二模式时，触控笔100可以距离电子设备200在指定范围1(例如，10米)内。当触控笔100接收到作用于触摸传感器44区域的输入1(例如，双击)时，触控笔100可以获取到第二模式下输入1对应的功能信号5，继而将该功能信号5发送给电子设备200，使得电子设备200响应于该功能信号5执行对应的功能5。
从上述方法中可以看出，在一些应用场景中，触控笔100可以响应于指定切换操作1或检测到强度小于指定数值1的指定信号1，进行功能模式的切换。触控笔100可以基于不同的功能模式，响应于接收到的输入，向电子设备200发送不同的功能信号，以使得电子设备200响应于该功能信号执行对应的功能。因此，操作十分方便，触控笔100可以应用的场景也更加广泛。

在一种可能的实现方式中，触控笔100可以检测到用户作用于触控笔100上的指定切换操作1，响应于该指定切换操作1，触控笔100可以进行功能模式的切换(例如，从第一模式切换至第二模式，或，从第二模式切换至第一模式)。其中，该指定操作1可以是例如作用于触摸传感器44区域上的多次触摸操作(例如，连续触摸触控笔100上触摸传感器44区域三次)、长按触摸传感器44区域上的操作等。本申请对此不作限制。
在一种可能的实现方式中，电子设备200可以检测触控笔100中电极释放的电信号。当电子设备200确定出触控笔100中电极释放的电信号小于指定数值1(例如。-50dbm)时，可以通过无线通信连接向触控笔100发送功能模式切换指令1，使得触控笔100可以基于该功能模式切换指令1从第一模式切换至第二模式。当电子设备200确定出触控笔100中电极释放的电信号大于指定数值1时，可以通过无线通信连接向触控笔100发送功能模式切换指令2，使得触控笔100可以基于该功能模式切换指令2从第二模式切换至第一模式。
S1207、触控笔100检测到用户针对触控笔100的第二输入。
具体的，该第二输入可以是前述图11A-图11T所示实施例中的输入4、输入5或输入6。
触控笔100可以通过触摸传感器采集到用户针对触控笔100上的操作数据，以及通过陀螺仪传感器采集到触控笔100的位移数据，进而将该操作数据和位移数据发送给处理器。处理器可以根据用户的操作数据和位移数据，检测到用户的第二输入，从而实现触控笔100检测到用户针对触控笔100的第二输入。也即是说，当触控笔100检测到用户作用于触摸 传感器44区域上的操作，同时触控笔100进行移动时，触控笔100即确定出用户针对触控笔100的第二输入，以使得该触控笔100可以基于第二输入执行后续操作。
S1208、触控笔100基于该第二输入，生成第二模式下该第二输入对应的第二功能信号。
具体的，触控笔100处于第二模式。
在该第二模式下，第二输入对应有第二功能信号，第二功能信号对应有第二功能。其中，第二功能信号可以是前述图11A-图11T所示实施例中的功能信号4、功能信号8或功能信号9。第二功能可以是前述图11A-图11T所示实施例中的功能4、功能8或功能9，例如移动光标功能、远距离笔迹书写的功能和启动指定应用的功能等。
当触控笔100检测到第二输入时，触控笔100可以生成第二模式下第二输入对应的第二功能信号。
S1209、触控笔100通过第一传感器，获取到触控笔100的位置信息。
具体的，该第一传感器可以是陀螺仪传感器。触控笔100可以通过陀螺仪传感器获取到触控笔100移动时的位置信息，然后，触控笔100可以每隔指定周期(例如，0.1秒)将获取到的位置信息发送给电子设备200。该位置信息可以是前述图11A-图11T所示实施例中的位移信息1或位移信息2。
在一种可能的实现方式中，该第一传感器也可以是加速度计。触控笔100可以通过该加速度计获取到触控笔100移动时的位置信息，并每隔指定周期(例如，0.1秒)将获取到的位置信息发送给电子设备200。
S1210、触控笔100发送第二功能信号和位置信息给电子设备200。
具体的，在第二模式下，触控笔100可以通过前述步骤S1201建立的无线通信连接向电子设备200发送第二功能信号和位置信息。
在本申请实施例中，无线通信连接以蓝牙连接为例。具体的，触控笔100和电子设备200均可以存储有：在第二模式下，各输入(例如，第二输入等)、功能信号(例如，第二功能信号)、功能信号中的标识(例如，第二功能信号中的第二标识等)与功能(例如，第二功能信号对应的第二功能等)的映射关系。其中，功能信号中的标识可以是功能的名称、编号等等。触控笔100在检测到用户对触控笔100的输入时，可以根据该输入以及上述映射关系，确定向电子设备200发送的功能信号中的标识。电子设备200在接收到功能信号中的标识后，可以根据该标识以及上述映射关系，确定需要执行哪种功能。
例如，当触控笔100接收到用户针对触控笔100的第二输入后，触控笔100可以基于第二模式下该第一输入和上述存储的映射关系，确定出向电子设备200发送的第二功能信号。触控笔100可以通过蓝牙模块发送第二功能信号和位置信息。其中，该第二功能信号为蓝牙信号。该第二功能信号中包括第二标识。
S1211、电子设备200接收到第二功能信号和位置信息后，基于该第二功能信号和位置 信息执行第二功能。
具体的，电子设备200可以通过第二功能中的第二标识，确定出所执行的第二功能。然后电子设备200可以基于位置信息执行第二功能。
示例性的，以图11I-图11J所示实施例为例，第二输入是按住该后侧区域，同时如图11J所示触控笔100进行移动，第三功能信号是功能信号4，第二功能是移动光标功能。电子设备200可以通过无线通信连接(例如，蓝牙连接)，接收触控笔100发送的第二功能信号和位置信息。其中，第二功能中包括第二标识，使得电子设备200基于该第二标识确定出所执行的第二功能。然后，电子设备200可以基于位置信息执行第二功能，使得显示屏上显示出光标以及该光标的移动效果。
在一些实施例中，电子设备200和触控笔100还可以存储有：第二模式下第一输入、第三功能信号、第三功能信号中的第三标识与第三功能的映射关系。也即是说，第一模式和第二模式下，触控笔100都可以接收到第一输入。在不同的模式下，触控笔100可以基于该第一输入生成不同的功能信号，以使得电子设备200基于不同的功能信号执行不同的功能。与第一模式不同，在第二模式下，第一输入对应的是第三功能信号以及第三功能。其中，第三功能信号和前述第一功能信号不同，第三功能和前述第一功能不同。其中，第三功能信号中的第三标识可以是功能的名称、编号等等。触控笔100在检测到用户对触控笔100的第一输入时，可以根据该输入以及上述映射关系，确定向电子设备200发送的第三功能信号以及其中的第三标识。电子设备200在接收到第三功能信号中的第三标识后，可以根据该标识以及上述映射关系，执行第三功能。
示例性的，以图11K-图11L为例，第一输入可以是双击触摸传感器区域，与第一模式下不同，该第一输入在第二模式下对应的第三功能信号是功能信号5，第三功能是启动选中的应用。电子设备200可以通过无线通信连接(例如，蓝牙连接)，接收触控笔100发送的第三功能信号。其中，第三功能信号中包括第三标识。电子设备200可以根据该第三标识，确定出所执行的第三功能，即是启动选中的绘画应用。而在第一模式下，如图11A-图11B所示，该第一输入对应的使得电子设备200执行的功能为橡皮擦功能。
