第四方面，本申请还提供了一种触控笔操作的处理方法，应用于触控笔，触控笔包括反馈装置，方法包括：与第一电子设备建立无线连接，第一电子设备包括第一触控屏；在第一条件下，采集触控笔的第一状态信息，第一条件包括触控笔的笔尖与第一触控屏接触，第一状态信息包括第一压力值，第一压力值指示触控笔在第一条件下的压力；当第一压力值大于或等于第一预设压力阈值时，控制反馈装置输出第一提示信号；与第二电子设备建立无线连接，第二电子设备包括第二触控屏；接收第二电子设备发送的第二预设压力阈值；在第二条件下，采集触控笔的第二状态信息，第二条件包括触控笔的笔尖与第二触控屏接触，第二状态信息包括第二压力值，第二压力值指示触控笔在第二条件下的压力；当第二压力值大于或等于第二预设压力阈值时，控制反馈装置输出第二提示信号；第一提示信号和第二提示信号均用于提示触控笔的压力大。可见，在跨设备使用触控笔、且触控笔具有反馈装置的场景，第二电子设备与第一触控笔建立无线连接后，第二电子设备可以向第一触控笔发送触控屏对应的预设压力阈值，当第一触控笔采集的书写压力值后，与第二电子设备发送的预设压力阈值进行比较，如果书写压力值大于或等于预设压力阈值，则控制第一触控笔的反馈装置输出提示信号。这样，节省了将书写压力值发送至电子设备的传输时间，因此，降低了提醒书写压力过大的时延，即提高了提醒书写压力过大的响应速度。而且，该方案中针对不同电子设备，触控笔都可以在检测到触控笔的书写压力超过电子设备 的屏幕类型相匹配的预设压力阈值后，触发书写压力保护机制，提高了触控笔的压力保护机制的通用性。
在第四方面一种可能的实现方式中，在接收第二电子设备发送的第二预设压力阈值后，方法还包括：触控笔存储第二预设压力阈值，以及建立第二预设压力阈值与第二电子设备之间的映射关系。这样，在第一触控笔与第二电子设备再次连接时，第一触控笔可以直接从本地读取与第二电子设备相匹配的第二预设压力阈值，不需要第二电子设备每次连接第一触控笔都向第一触控笔发送预设压力阈值。
在第四方面另一种可能的实现方式中，反馈装置包括以下至少一项：振动马达、状态指示器和扬声器；提示信号包括以下至少一项：振动马达输出的振动信号，状态指示器输出的光信号，以及扬声器输出的声音信号。
第五方面，本申请还提供了一种触控笔操作的处理方法，应用于电子设备，该电子设备包括触控屏，该方法包括：与触控笔建立无线连接；向触控笔发送预设压力阈值，预设压力阈值用于使触控笔检测到压力值大于或等于预设压力值时输出提示信号，压力值指示触控笔在第一条件下与触控屏之间的压力，第一条件包括触控笔的笔尖与触控屏接触，提示信号用于提示触控笔的压力大。可见，当电子设备与其他电子设备连接时，将自身屏幕类型对应的预设压力阈值发送至触控笔，使得触控笔在检测到触控笔的书写压力超过当前屏幕对应的预设压力阈值后，及时输出提示信号，提高了提醒书写压力过大的响应速度。进一步，使得用户及时调整书写压力，避免电子设备的触控屏因触控笔的书写压力过大而损坏。
第六方面，本申请还提供了一种触控笔操作的处理方法，应用于系统，该系统包括触控笔、第一电子设备和第二电子设备，触控笔包括反馈装置，第一电子设备包括第一触控屏，第二电子设备包括第二触控屏，该方法包括：触控笔与第一电子设备建立无线连接；触控笔在第一条件下，采集触控笔的第一状态信息，第一条件包括触控笔的笔尖与第一触控屏接触，第一状态信息包括第一压力值，第一压力值指示触控笔在第一条件下的压力；触控笔检测到第一压力值大于或等于第一预设压力阈值后，控制反馈装置输出第一提示信号；触控笔将第一状态信息发送至第一电子设备；第一电子设备基于第一状态信息，响应触控笔在第一触控屏上的操作；触控笔与第二电子设备建立无线连接；第二电子设备向触控笔发送第二预设压力阈值；触控笔在第二状态下，采集触控笔的第二状态信息，第二状态包括触控笔的笔尖与第二触控屏接触，第二状态信息包括第二压力值，第二压力值指示触控笔在第二状态下的压力；触控笔检测到第二压力值大于或等于第二预设压力阈值后，控制反馈装置输出第二提示信号；第一提示信号和第二提示信号均用于提示触控笔的压力大。

具体实施方式
本申请说明书和权利要求书及附图说明中的术语“第一”、“第二”和“第三”等是用于区别不同对象，而不是用于限定特定顺序。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如” 等词旨在以具体方式呈现相关概念。
图1为本申请实施例适用的一种场景示意图，如图1所示，该场景包括电子设备1、触控笔(stylus)2。电子设备1具有触控屏11，该触控屏11可以称为触摸屏，图1中以电子设备1是折叠屏手机为示例。触控笔2可以称为手写笔。
电子设备1基于触控笔2的输入执行响应于该输入的操作。在一实施例中，触控笔2与电子设备1之间可以通过通信网络进行互联，以实现无线信号的交互。通信网络可以包括但不限于：WiFi热点网络、WiFi点对点(peer-to-peer，P2P)网络、蓝牙网络、zigbee网络或近场通信(near field communication，NFC)网络等近距离通信网络。
触控笔2可以但不限于为电磁笔和电容笔。触控笔2为电磁笔时，电子设备1的触控屏11上需要集成电磁感应板。电磁感应板上的分布有线圈，电磁笔中也集成有线圈。基于电磁感应原理，在电磁感应板所产生的磁场范围内，随着电磁笔的移动，电磁笔能够积蓄电能。电磁笔可以将积蓄的电能通过自由震荡，经电磁笔中的线圈传输至电磁感应板。电磁感应板可以基于来自电磁笔的电能，对电磁感应板上的线圈进行扫描，计算出电磁笔在触控屏11上的位置。
电容笔可以包括:无源电容笔和有源电容笔。无源电容笔可以称为被动式电容笔，有源电容笔可以称为主动式电容笔。应理解，本申请实施例涉及的触控笔为有源电容笔。
主动式电容笔中(例如笔尖内)可以设置一个或多个电极，主动式电容笔可以通过电极发射信号。触控笔2为主动式电容笔时，电子设备1的触控屏11上需要集成电极阵列。在一实施例中，电极阵列可以为电容式电极阵列。电子设备1通过电极阵列可以接收来自主动式电容笔的信号，进而在接收到该信号时，基于触控屏11上的电容值变化识别主动式电容笔在触控屏上的位置，以及主动式电容笔的倾角。应理解，本申请实施例采用的触控笔为主动式电容笔，或简称为主动笔。
如图2的(1)所示，折叠屏手机处于完全展开状态，从该状态向外弯折可以获得图2的(2)所示的状态，从图2的(2)所示的状态继续向外弯折，获得图2的(3)所示的状态，图2的(3)所示的状态下，手机处于完全折叠状态。柔性屏幕的盖板主要为软性盖板，因此柔性屏幕可以实现弯折。由于软性盖板较软，当使用触控笔在柔性屏幕上书写时，极易在盖板上留下划痕，从而影响柔性屏幕的使用寿命。
为了解决上述问题，本申请实施例提供了一种触控笔操作的处理方法，当触控笔处于书写状态时，获取触控笔与电子设备的触控屏之间的压力值，如果压力值大于或等于预设压力阈值，则提示用户压力过大。用户在感知到该提示后，调整压力。可见，该方案在检测到触控笔的压力较大时可以及时提醒用户，使得用户及时调整压力，从而避免了触控笔压力过大而缩短触控屏的使用寿命，因此，采用该方案可以在一定程度上提高触控屏的使用寿命。
本文中，触控笔的书写状态是指触控笔处于工作状态，此种状态下触控笔可以在触控屏上进行相应的操作，如单击、双击、长按、写字、绘制图形等。
图3是本申请实施例提供的一种触控笔的结构示意图，如图3所示，触控笔可以包括笔尖101、笔杆102和后盖103。笔杆102的内部为中空结构，笔尖101和后盖103分别位于笔杆102的两端，后盖103与笔杆102之间可以通过插接或者卡合方式。
图4是本申请实施例提供的触控笔的部分内部结构示意图，如图4所示，触控笔还包括主轴组件104，主轴组件104位于笔杆102内，且主轴组件104在笔杆102内可滑动设置。主轴组件104上具有外螺纹，笔尖101包括书写端105和连接端106，其中，笔尖101的连接端106具有与外螺纹配合的内螺纹(未示出)。
当主轴组件104装配到笔杆102内时，笔尖101的连接端106伸入笔杆102内且与主轴组件104通过螺纹连接。在其他示例中，笔尖101的连接端106与主轴组件104之间还可以通过卡合等可拆卸方式实现连接。通过笔尖101的连接端106与主轴组件104之间可拆卸相连，实现了笔尖101的更换。
如图3所示，笔尖101与笔杆102之间具有间隙1011，这样可以确保笔尖101的书写端105受到外力时，笔尖101可以朝向笔杆102移动，笔尖101的移动会带动主轴组件104在笔杆102内移动。而对外力的检测，如图4所示，在主轴组件104上设有压感组件107，压感组件107的部分与笔杆102内的固定结构固定相连，压感组件107的部分与主轴组件104固定相连。这样，主轴组件104随着笔尖101移动时，由于压感组件107的部分与笔杆102内的固定结构固定相连，所以主轴组件104的移动会驱动压感组件107形变，压感组件107的形变传递给电路板108(例如，压感组件107与电路板108之间可以通过导线或者柔性电路板实现电连接)，电路板108根据压感组件107形变检测出笔尖101的书写端105的压力，从而实现了根据笔尖101书写端105的压力控制书写线条粗细。
需要说明的是，笔尖101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101的书写端105内设置压力传感器，由压力传感器检测笔尖101的压力。
如图4所示，触控笔还包括多个电极，此处以触控笔包括第一发射电极109、接地电极110和第二发射电极111为例进行说明，当然，在其他实施例中，触控笔还可以包括其他数量和作用的电极，此处不再赘述。
在一示例性实施例中，第二发射电极111可以位于笔杆102的内壁上。在另一种示例中，第二发射电极111也可以位于主轴组件104上。接地电极110可以位于第一发射电极109和第二发射电极111之间，或者，接地电极110可以位于第一发射电极109和第二发射电极111的外周围，接地电极110用于降低第一发射电极109和第二发射电极111相互之间的耦合。
第一发射电极109、接地电极110和第二发射电极111均与电路板108电连接。第一发射电极109可以位于笔尖101内且靠近书写端105。
电路板108可以被配置为可以分别向第一发射电极109和第二发射电极111提供信号的控制板。
第一发射电极109用于发射第一信号，当第一发射电极109靠近电子设备的触控屏时，第一发射电极109与电子设备的触控屏之间形成耦合电容，这样电子设备可以接收到第一信号。当电子设备接收来自触控笔的第一信号时，触控屏对应位置处的电容值会发生变化，电子设备可以基于触控屏上的电容值的变化，确定触控笔(或触控笔的笔尖)在触控屏上的位置。
在一示例性实施例中，第二发射电极111用于发射第二信号，电子设备根据接收到的第二信号可以判断触控笔的倾斜角度。其中，第一发射电极109和第二发射电极111在触 控笔中的位置不同，因此当电子设备接收来自触控笔的第一信号和第二信号时，触控屏上两个位置处的电容值会发生变化。电子设备可以根据第一发射电极109和第二发射电极111之间的距离，以及触控屏上电容值发生变化的两个位置处之间的距离，获取触控笔的倾斜角度。
本申请实施例中，如图4所示，触控笔还包括电池组件112，电池组件112用于向电路板108提供电源。其中，电池组件112可以包括锂离子电池，或者，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112包括的电池可以为可充电电池或一次性电池，若为可充电电池，触控笔可以通过无线充电方式进行充电。
图5是本申请实施例提供的一种触控笔的硬件结构示意图。如图5所示，触控笔可以包括处理器201、压力传感器202、惯性传感器203、状态指示器204、按钮205、电极206、感测电路207、无线通信模块、充电模块209。

触控笔可以包括一个或多个传感器。例如，压力传感器202。此处的压力传感器202即图4所示的压感组件107。压力传感器202用于检测触控笔的书写端的压力。
传感器还可以包括惯性传感器203。惯性传感器203可以包括三轴加速计和三轴陀螺仪，和/或，用于测量触控笔的运动的其它部件，例如，加速度传感器，或者三轴磁力计等。传感器也可以包括如温度传感器、环境光传感器、基于光的接近传感器、接触传感器、磁传感器等。
触控笔还可以包括如发光二极管的状态指示器204和按钮205。状态指示器204用于向用户提示触控笔的状态。按钮205可以包括机械按钮和非机械按钮，触控笔可以收集按钮205的按压信息。
本申请实施例中，触控笔还可以包括一个或多个电极206。其中一个电极可以位于触控笔的书写端处，其中一个电极可以位于笔尖内，可以参照上述图4的相关描述。
触控笔还可以包括感测电路207。感测电路207可感测位于电极206和与触控笔交互的电子设备的触控屏的耦合电容值，从而使得触控笔可以感测到与触控屏的接触。
可以理解的是，根据实际需求，触控笔还可以包括麦克风、扬声器、音频发生器、振动器(或称为振动马达)、相机、数据端口以及其它组件。用户可以通过利用这些组件提供命令来控制触控笔和电子设备的操作，并且接收状态信息和其它输出等。
为了支持触控笔与电子设备的无线通信，触控笔可以包括无线模块。图5以无线通信模块为蓝牙模块208为例进行说明。无线通信模块还可以为WI-FI热点模块、WI-FI点对点模块等。蓝牙模块208可以包括射频收发器，例如收发器。蓝牙模块208也可以包括一个或多个天线。收发器可以利用天线发射和/或接收无线信号，无线信号可以是蓝牙信号、无线局域网信号、近场通信信号、诸如蜂窝网络信号的远程信号或其它无线信号。
处理器201用于运行控制触控笔的操作的软件。在操作触控笔的过程中，运行在处理 器201上的软件可以处理传感器输入、按钮输入和来自其他装置的输入以监测触控笔的移动和用户输入等。运行在处理器201上的软件可以检测用户命令并通过蓝牙模块208与电子设备通信。
在一种应用场景中，触控笔内部还可以设置有反馈装置，如振动马达、扬声器、状态指示器等。触控笔的处理器201可以运行用于执行本申请实施例提供的触控笔操作的处理方法的软件，处理器201执行该软件可以实现在检测到触控笔处于书写状态时的压力值大于或等于预设压力阈值时，控制反馈装置运行，如振动马达进行振动，和/或，扬声器播放声音信号，如压力过大的语音提示信息或播放报警声，和/或，点亮指示灯(如，按预设颜色或频率控制指示灯点亮)。
在另一种应用场景中，可以在与触控笔交互的电子设备的处理器内运行本申请实施例提供的触控笔操作的处理方法。可以应用本申请实施例提供的触控笔操作的处理方法的电子设备可以是手机、平板电脑、笔记本电脑、手持计算机、上网本、可穿戴电子设备等具有触控屏的电子设备。
请参见图6，示出了本申请实施例提供的一种电子设备的结构示意图。
如图6所示，电子设备可以包括处理器301、触控屏302、存储器303、无线通信模块304、天线305和电源子系统306。
处理器301可以包括一个或多个处理单元，例如，处理器可以包括应用处理器、数字信号处理器等，其中，不同的处理单元可以是独立的器件，也可以集成在一个或多个处理器中。
例如，在本申请中，处理器301可以在检测到触控笔的压力大于压力阈值时，使得电子设备输出提示用户压力过大的提示信号。
存储器303可以用于存储计算机可执行程序代码，该可执行程序代码包括指令。处理器301通过运行存储在储存器303的指令，以执行电子设备的各种功能应用以及数据处理。
触控屏302用于显示图像、视频等，还可以显示一些利图像用户界面(graphical user interface，GUI)，这些GUI都是电子设备的主屏幕。而且，触控屏302还可以检测操作体(如，手指、触控笔等)作用于其上或附近的触控操作，并将检测到的触控操作传递给应用处理器进行相应的处理。

下面将结合附图详细说明本申请实施例提供的触控笔操作的处理方法实施例。
在一种应用场景中，如图1所示，折叠屏手机1配置有触控笔2，利用触控笔2在折叠屏手机1的触控屏11上书写。此种场景下，可以包括以下两种可能的实现方式：
一种可能的实现方式是：触控笔内未设置反馈装置，如未设置振动马达、状态指示器， 和/或扬声器等。此种可能的实现方式下，由与该触控笔交互的电子设备判断触控笔发送的书写状态下的压力值，若压力值大于或等于预设压力阈值，则控制该电子设备输出用于提醒用户触控笔的压力过大的提示信号。
另一种可能的实现方式是：触控笔内设置有反馈装置，如振动马达、状态指示器，和/或扬声器，此种场景下，触控笔内的处理器判断触控笔的压力值是否大于或等于预设压力阈值，如果是，则直接控制触控笔内的反馈装置输出相应的提示信号。
可选地，电子设备还可以接收触控笔发送的书写状态下的压力值，并判断该压力值是否大于或等于预设压力阈值，如果是则触发电子设备输出触控笔的压力过大的提示信号。
对于上述的触控笔内未设置反馈装置的实现方式，本申请实施例提供了如图7所示的触控笔操作的处理流程，该方法应用于与触控笔进行交互的电子设备中，例如，配置有触控笔的电子设备。如图7所示，该方法可以包括以下步骤：
S11，触控笔与电子设备之间建立无线连接。
以触控笔与电子设备之间建立蓝牙连接为例进行说明，在本申请的其他实施例中，触控笔与电子设备之间可以建立基于除蓝牙协议之外的其他无线连接，本申请对触控笔与电子设备之间的无线通信类型不做限制。
在一种可能的实现方式中，触控笔与电子设备首次连接时，建立无线连接的过程可以包括三个阶段分别为：配对阶段、蓝牙信息传输阶段和建立无线通道阶段。
其中，配对阶段是触控笔向电子设备发送握手数据，电子设备对接收的触控笔的握手数据对触控笔进行设备校验，并向触控笔返回校验结果。
握手数据可以包括触控笔的设备相关信息，如，触控笔的设备名称、产品序列号、软件系统信息、产品硬件信息等，本申请对此不做限定。
电子设备在出厂时存储有相适配的触控笔的设备信息，即电子设备内存储有相适配的触控笔的设备名称、设备型号、软件系统的版本信息、产品硬件信息等设备信息。电子设备将接收的触控笔的设备信息与自身存储的触控笔的设备信息进行设备校验。
与电子设备相适配的触控笔可以是一种或多种类型，电子设备可以存储相适配的每一种类型的触控笔的设备信息，本申请对此不做限定。
如果电子设备对触控笔的设备校验信息失败，即该触控笔不是与电子设备相适配的触控笔，可以终止当前的配对流程，不再执行后续的其他步骤。
如果电子设备对触控笔校验通过，则向触控笔返回指示校验通过的校验结果，触控笔接收该校验结果后，向电子设备发送蓝牙信息。
进一步，电子设备将接收的蓝牙信息与自身内存储的相适配的触控笔的蓝牙信息进行对比，即对触控笔的蓝牙信息进行校验，并向触控笔返回蓝牙信息校验结果。
在一示例中，触控笔的蓝牙信息可以包括：该触控笔的蓝牙协议信息、无线信息、蓝牙连接时的媒体访问控制(media access control，MAC)地址信息、互联网协议地址(Internet protocol address，IP address)等与蓝牙连接相关的信息，本申请对此不做限定。这些蓝牙信息用于支持电子设备与触控笔之间建立蓝牙通道。
如果电子设备对触控笔的蓝牙信息校验通过，则继续执行后续的步骤，如显示连接提示弹窗，该连接提示弹窗用于显示是否连接该触控笔，且可以显示“是”和“否”的控件， 进一步，根据用户的选择执行相应的流程。例如，若用户选择“是”，则继续执行触控笔与电子设备之间建立无线通道(如蓝牙通道)的流程。若用户选择“否”，则可以终止当前流程，不再执行后续的步骤。
可选地，该连接提示弹窗还可以显示当前触控笔的产品信号、生产厂家等内容，以及当前触控笔的剩余电量、电池标识、充电进度等内容中的至少一项。
如果电子设备对触控笔的蓝牙信息校验失败(即，触控笔的蓝牙信息校验未通过)，可以终止当前流程，即不再执行后续步骤。
S12，触控笔确定自身处于书写状态后，采集书写压力值。
本申请实施例中，书写状态即第一条件。
在一种可能的实现方式中，书写状态包括触控笔的笔尖与触控屏接触，此外，还可以包括其他内容，如笔尖与触控屏接触的时长超过预设时长，其中预设时长可以根据实际需求设定。
触控笔处于书写状态时，触控笔可以在电子设备的触控屏进行操作，如单击、双击、长按、写字、绘制图形等。
在本申请实施例中，触控笔进入书写状态后，触控笔会触发内部的传感器采集相应的信息，采集的这些信息可以称为触控笔的状态信息，如状态信息包括上述的书写压力值。
当触控笔的笔尖接触电子设备的触控屏时，触控屏上接触位置的电容值发生变化，基于此电子设备确定触控笔处于书写状态，电子设备向触控笔发送信号，触控笔接收该信号后确定当前处于书写状态。触控笔确定自身与触控屏接触后，触发触控笔内的相应传感器采集触控笔的状态信息，例如，利用触控笔内的压力传感器采集书写端的压力数据，即书写压力值。
S13，触控笔将书写压力值发送至电子设备。
触控笔将自身的状态信息(包括书写压力值)通过触控笔与电子设备之间的无线通道(如蓝牙通道)上报至电子设备。S14，电子设备判断书写压力值是否大于或等于预设压力阈值；如果是，则执行S15；如果否，则执行S16。
电子设备解析触控笔上报的数据获得书写压力数据，进一步判断书写压力值是否大于或等于预设压力阈值。
在一示例中，压力值的单位可以是g，g表征9.8N/kg。
预设压力阈值可以根据不同触控屏类型的要求设定，例如，柔性屏幕能够承受的压力较小，因此柔性屏幕的预设压力阈值可以设置为较小的值，如150g。与柔性屏幕相比，硬性屏幕能够承受的压力较大，因此硬性屏幕的预设压力阈值可以设置为较大的值如，400g左右。
S15，电子设备输出提示信号。
本申请实施例中，提示信号可以包括显示提示弹窗和输出其他提示信号中的至少一项。
提示弹窗包括提醒用户触控笔压力过大的提示信息，如文本信息。在一示例性实施例中，其他提示信号包括但不限于为：振动马达输出振动信号，和/或，扬声器输出声音信号，和/或，状态指示器输出灯光信号。
如图8所示，可以在触控屏11上显示提示弹窗12。其中，可以根据实际需求设置该提 示弹窗12的显示内容，如图8所示，提示弹窗12的显示内容可以是“您的书写压力过大，存在触控屏损坏的风险”。例如，如图7所示，提示弹窗12位于触控笔2在触控屏11的书写位置的上方。当然，提示弹窗12还可以位于触控屏11的任意显示位置，本申请对此不做限定。
用户看到提示弹窗的内容和/或感知到其他提示信号后，可以及时调整书写压力，从而避免用户使用触控笔的书写压力过大损伤触控屏的现象发生。
在一示例性实施例中，电子设备执行S15之后继续执行S16，例如，显示提示弹窗预设时长，如5s后(或输出其他提示信号预设时长)继续执行S16。
S16，电子设备响应触控笔在触控屏上的操作。
在一种情况下，触控笔的书写压力大于或等于触控屏的预设压力阈值，电子设备显示提示弹窗、输出其他提示信号。以及，响应触控笔在触控屏上的操作。在另一种情况下，触控笔的书写压力小于触控屏的预设压力阈值，此种情况下，不显示提示弹窗和其他提示信号，直接响应触控笔在触控屏上的操作。
电子设备根据触控笔的操作类型，执行与操作类型相匹配的响应处理，如，触控笔在触控屏上进行了点击操作(或双击、长按等)，电子设备响应该操作，执行相应的处理流程。如触控笔在触控屏上进行了书写或绘制图形等操作，则直接执行绘制笔迹的操作，即控制触控笔出水。
本实施例提供的触控笔操作的处理方法，触控笔处于书写状态时采集书写端的压力值，即书写压力值，并将该书写压力值发送至电子设备。电子设备确定书写压力值大于或等于预设压力阈值后，电子设备输出用于提示用户书写压力过大的提示信号，如显示提示弹窗、振动马达输出振动信号、扬声器输出报警信号等至少一种。可见，该方案在检测触控笔书写压力过大可能导致触控屏损伤时，及时输出相应的提示信号，以便用户根据提示信号的提示调整书写压力，避免触控笔书写压力过大导致触控屏损伤，提高了触控屏的使用寿命。
针对触控笔内设置有反馈装置的实现方式，触控笔内的处理器可以判断自身的书写压力值是否超过预设压力阈值，如果判定自身的书写压力至超过预设压力阈值，则直接驱动触控笔中的反馈装置输出提示信号。
本申请实施例提供了图9所示的另一种触控笔操作的处理方法。如图9所示，该方法可以包括以下步骤：
S21，触控笔与电子设备之间建立无线连接。
S22，触控笔响应于进入书写状态，采集书写压力值。
本实施例的书写状态即第一状态，书写压力值也即压力值。
S23，触控笔将采集的书写压力值通过无线通信连接上报至电子设备。
本实施例中S21～S23的过程与图7所示实施例中的S11～S13的过程相同，此处不再赘述。
S24，触控笔判断书写压力值是否大于或等于预设压力阈值；如果是，则执行S25；如果否，则结束当前流程。
S25，触控笔控制触控笔内的反馈装置输出提示信号。
本实施例中，触控笔内设置有反馈装置，如振动马达、扬声器、状态指示灯等，此种 场景下，触控笔内的处理器可以在判定书写压力值超过预设压力阈值时，触发触控笔内的反馈装置输出相应的提示信号，如振动马达振动、扬声器播放报警信号、状态指示灯显示相应的光信号。
S26，电子设备判断接收的书写压力值是否大于或等于预设压力阈值；如果是，则执行S27；如果否，则执行S28。
S27，电子设备输出提示信号。
触控笔的状态信息会发送至电子设备，因此，电子设备也可以判断接收的书写压力值是否超过预设压力阈值，若是则触发电子设备侧输出相应的提示信号，如显示提示弹窗，和/或输出其他类型的提示信号，如振动、声音信号或光信号等。
提示弹窗提示触控笔书写压力过大的信息，用户可以更直观地、准确地获知触控笔的书写压力过大，方便用户及时获知压力过大的提示信息，进一步及时调整书写压力。
S28，电子设备响应触控笔在触控屏上的操作。
如果电子设备确定书写压力值超过预设压力阈值，则控制电子设备输出提示信号，与此同时，响应触控笔在触控屏上的操作，如，触控笔在触控屏上移动，则执行绘制笔迹的操作。
如果电子设备确定书写压力值小于预设压力阈值，则电子设备直接执行绘制笔迹的操作。
应理解，S26～S28不是必须执行的步骤，即可以仅执行本实施例中的S21～S25，也即可以仅由触控笔检测到书写压力值超标时，输出提示信号，与触控笔交互的电子设备侧无需重复检测并提示。
本实施例提供的触控笔操作的处理方法，触控笔获得书写压力值后，直接由触控笔内的处理器判断书写压力值是否超过预设压力阈值，并在书写压力超过预设压力阈值时，直接由触控笔输出提示信号。此过程节省了将书写压力值发送至电子设备的传输时间，因此，降低了提醒书写压力过大的时延，即提高了提醒书写压力过大的响应速度。而且，直接由触控笔的反馈装置输出提示信号，以便用户直接感知触控笔的反馈，提高了用户体验。
进一步地，该方案电子设备也可以继续执行判断书写压力值是否超标、且确定超标则输出提示信号的过程，即如果触控笔书写压力超标，则触控笔和电子设备都会输出相应的提示信号，两个设备均输出提示信号提高了提示信号的有效性。
在另一种应用场景中，一电子设备(如第一电子设备)配置有触控笔，利用该触控笔在另一电子设备(如第二电子设备)的触控屏上操作，即跨设备的触控笔操作。
如图10所示，折叠屏手机501为第一电子设备，折叠屏手机501配置有触控笔502(可称为第一触控笔)，平板设备503为第二电子设备，该场景是用户使用触控笔502在平板设备503上操作。又如图11所示，平板设备601为第一电子设备，折叠屏手机603为第二电子设备，平板设备601配置有触控笔602，该场景是用户使用平板设备601的触控笔602在折叠屏手机603上操作。
此种场景下，可以包括以下两种可能的实现方式：
一种可能的实现方式是，当跨设备使用触控笔时，触发与触控笔交互的电子设备侧的书写过压保护机制，即直接由第二电子设备执行书写过压保护机制的处理流程，此过程与 图7所示的触控笔操作的处理方法相同，此处不再赘述。由此可见，在电子设备侧具有书写过压保护机制的情况下，与电子设备使用的触控笔无关，更换与电子设备连接的触控笔后，电子设备同样可以监控触控笔的书写压力，避免触控笔书写压力过大导致触控屏损伤，提高了触控屏的使用寿命。
另一种可能的实现方式是，触控笔内设置有反馈装置，如振动马达、状态指示灯、扬声器等。当跨设备使用触控笔时，可以触发触控笔侧的书写过压保护机制。但是，在如图11所示的应用场景中，触控笔602内的书写过压保护机制是针对平板设备601的触控屏(即硬性屏幕)配置预设压力阈值，而折叠屏手机603内的书写过压保护机制是针对折叠屏手机的柔性屏幕配置预设压力阈值。当触控笔602在折叠屏手机上书写时，触控笔602仍按硬性屏幕的预设压力阈值触发书写过压保护机制。前已叙及，柔性屏幕能承受的压力较小，而硬性屏幕能够承受的压力较大，例如，硬性屏幕的预设压力阈值为400g，若触控笔在柔性屏幕上的书写压力达到600g已经远远超过柔性屏幕的阈值(如150g)，必然会导致柔性屏幕过压损坏。因此，此种实现方式中，与触控笔交互的电子设备需要将触控屏对应的预设压力阈值发送给触控笔，触发触控笔按照当前书写的触控屏的预设压力阈值执行相应的书写过压保护机制。
参见图12是本申请实施例提供的另一种实现方式对应的触控笔操作的处理流程图。如图12所示，该方法可以包括以下步骤：
S31，第一触控笔与第一电子设备之间建立无线连接。
S32，第一触控笔进入书写状态后，采集第一书写压力值。
本实施例的触控笔进入书写状态后即触控笔在第一条件下。书写压力值即第一压力值。
S33，第一触控笔向第一电子设备上报第一书写压力值。
S34，第一触控笔判断第一书写压力值是否大于或等于第一预设压力阈值。如果是，则执行S35；如果否，则结束当前流程。
第一预设压力阈值与第一电子设备的触控屏的屏幕类型相匹配，例如，第一电子设备的触控屏是柔性屏幕，则该第一预设压力阈值约为150g左右。第一电子设备的触控屏是硬性屏幕，则第一预设压力阈值约为400g左右。
S35，第一触控笔输出第一提示信号。
本实施例中，第一触控笔内设置有反馈装置，如振动马达、状态指示器和扬声器中的至少一项。此种场景下，第一提示信号可以包括以下至少一项：振动马达输出的振动信号，状态指示器输出的光信号，以及扬声器输出的声音信号。
可选地，第一电子设备还可以执行S36～S38所示的过程。
S36，第一电子设备判断第一书写压力值是否大于或等于第一预设压力阈值。如果是，则执行S37；如果否，则执行S38。
S37，第一电子设备输出第二提示信号。
在一种可能的实现方式中，如果第一书写压力值大于或等于第一预设压力阈值，第一电子设备的触控屏显示第一提示弹窗，该第一提示弹窗包括提醒所述触控笔的压力值过大的提示信息。
在另一种可能的实现方式中，第一电子设备包括反馈装置，如振动马达、状态指示器 和扬声器中的至少一项。此种场景下，第二提示信号可以包括以下至少一项：振动马达输出的振动信号，状态指示器输出的光信号，以及扬声器输出的声音信号。
S38，第一电子设备响应触控笔在第一触控屏上的操作。
本实施例中的S31～S38与图9所示实施例中的S21～S28的过程相同，此处不再赘述。此外，S36～S38所示过程是可选过程，此处不再赘述。
S39，第一触控笔与第二电子设备之间建立无线连接。
本申请中，与第一触控笔配套的电子设备称为第一电子设备，第二电子设备配套的触控笔称为第二触控笔，本实施例是跨设备使用触控笔的场景，如第二电子设备与第一触控笔进行交互，或者，第一电子设备与第二触控笔交互。
S310，第二电子设备向第一触控笔发送第二预设压力阈值。
本一示例性实施例中，第二电子设备与第一触控笔建立无线连接后，即可将第二电子设备的触控屏(即第二触控屏)对应的第二预设压力阈值发送给第一触控笔。这样，第一触控笔可以及时检测书写压力值是否超标，降低了提醒书写压力过大的时延，即提高了提醒书写压力过大的响应速度。
应理解，第二电子设备还可以在其他时机向第一触控笔发送第二预设压力阈值，例如，第二电子设备在接收到第一触控笔发送的第二压力值后，再向第一触控笔发送第二预设压力阈值。
在一种可能的实现方式中，第二电子设备确定连接的触控笔是新的触控笔(即，之前未连接过的触控笔)，第二电子设备主动将与自身的触控屏对应的预设压力阈值发送给第二触控笔。
在另一种可能的实现方式中，当第一触控笔确定连接的电子设备是新的电子设备(即，之前未连接过的电子设备，如第二电子设备)后，第一触控笔主动向第二电子设备发送获取预设压力阈值的请求，第二电子设备响应获取预设压力阈值的请求向第一触控笔发送与自身的触控屏对应的预设压力阈值。
S311，第一触控笔存储第二电子设备与第二预设压力阈值之间的映射关系。
在一示例性实施例中，第一触控笔接收第二电子设备发送的第二预设压力阈值后，可以存储该第二预设压力阈值及第二电子设备之间的映射关系。这样，在第一触控笔与第二电子设备再次连接时，第一触控笔可以直接从本地读取与第二电子设备相匹配的第二预设压力阈值，不需要第二电子设备每次连接第一触控笔都向第一触控笔发送预设压力阈值。例如，第一触控笔与第二电子设备建立无线连接后，基于接收的第二电子设备的设备信息从第一触控笔本地查询与该设备信息相匹配的预设压力阈值。
S312，第一触控笔进入书写状态后，采集第二书写压力值。
此处的书写状态即第二状态，此处的第二书写压力值即第二压力值。
S313，第一触控笔向第二电子设备发送第二书写压力值。
S314，第一触控笔判断第二书写压力值是否大于或等于第二预设压力阈值；如果是，则执行S315；如果否，则结束当前流程。
S315，第一触控笔输出第三提示信号。
可选地，本实施例中的第二电子设备还可以执行以下步骤S314～S316。
S316，第二电子设备判断第二书写压力值是否大于或等于第二预设压力阈值；如果是，则执行S317；如果否，则执行S318。
S317，第二电子设备执行显示提示弹窗以及输出其他提示信号中的至少一项。
S318，第二电子设备响应第一触控笔在第二触控屏上的操作。
在本实施例中，如果第二电子设备在判定第二书写压力值不大于第二预设压力阈值，则直接响应第一触控屏的操作，如执行绘制笔迹的操作。
本实施例中的S316～S318也不是必须执行的步骤，即可以仅由触控笔检测到书写压力值超标时，输出提示信号，与触控笔交互的电子设备侧无需重复检测并提示。
本实施例提供的触控笔操作的处理方法，适用于跨设备使用触控笔、且触控笔具有反馈装置的场景，第二电子设备与第一触控笔建立无线连接后，第二电子设备可以向第一触控笔发送触控屏对应的预设压力阈值，当第一触控笔采集的书写压力值后，与第二电子设备发送的预设压力阈值进行比较，如果书写压力值大于或等于预设压力阈值，则控制第一触控笔的反馈装置输出提示信号。这样，节省了将书写压力值发送至电子设备的传输时间，因此，降低了提醒书写压力过大的时延，即提高了提醒书写压力过大的响应速度。而且，直接由触控笔的反馈装置输出提示信号，以便用户直接感知触控笔的反馈，提高了用户体验。
进一步地，第二电子设备也可以继续执行判断书写压力值是否超标、且确定超标则输出提示信号的过程，即如果触控笔书写压力超标，则触控笔和电子设备都会输出相应的提示信号，触控笔和电子设备均输出提示信号可以提高提示信号的有效性。
