具体的，本实施例中提供一种主动笔，包括主动笔本体10和设置于所述主动笔本体10的笔尖上的信号发射模块，所述信号发射模块用于发射第一信号，使得触控屏根据所述第一信号获取主动笔与触控屏的接触位置，
所述主动笔本体10内还设置有倾斜角检测结构，包括信号接收模块和处理模块，所述信号接收模块用于在所述信号发射模块发射所述第一信号的同时、同步接收所述第一信号，所述处理模块根据所述信号接收模块接收的所述第一信号的强度获得所述主动笔本体10的倾斜角度，其中，所述信号发射模块与所述信号接收模块之间的距离越远、所述信号接收模块接收的所述第一信号的强度越弱、所述主动笔本体10的倾斜角度越小，其中，所述倾斜角 度为所述主动笔本体10与触控屏所在的平面之间的角度，参考图5-图7。
图3表示增设了倾斜角检测结构的主动笔结构示意图，包括笔尖5、压力传感器和倾斜检测部分1、信号发射和处理器2、电源3、功能开关4等部分，图4表示本实施例中主动笔分时复用示意图，其中，D表示Display time(显示时间)，P(包括P0、P1、P2和P3)表示avtive pen time(主动笔触控检测时间)，F表示finger time(手指触控检测时间)，通过所述倾斜角检测结构的设置进行主动笔倾斜角度的检测，所述信号发射模块发射第一信号，所述倾斜角检测结构的所述信号接收模块同步接收所述第一信号、以进行主动笔的倾斜角度检测，即将主动笔的倾斜角度检测与主动笔的触控检测同步到同一时序中，将图2和图4进行对比，图2中主动笔的倾斜检测单独占用了2个TP小坑，而图4中，将主动笔的倾斜检测与主动笔的触控检测同步到一个TP小坑内，则图2中原本用来进行主动笔倾斜检测的TP小坑则可以用于手指触控检测，这样就提高了手指触控的报点率。
所述倾斜检测结构的具体结构形式可以有多种，本实施例中，所述倾斜角检测结构包括：
设置于所述主动笔本体10内的空心半球体30，所述半球体30的球面面向笔尖20设置，所述半球体30的平面与所述主动笔本体10的径向方向相平行；
摆动组件，包括设置于所述半球体30的球心的固定座，活动连接于所述固定座上的摆动件，所述摆动件位于所述半球体30内部，所述摆动件远离所述半球体30的球心的一端内固定设置有所述信号接收模块，且所述摆动件远离所述半球体30的球心的一端与所述半球体30的球面接触、并能够随着所述主动笔本体10的倾斜、在所述半球体30的球面上、沿着任意方向进行钟摆运动。
如图5所示，在所述主动笔本体10垂直于触控屏所在的平面时，即所述主动笔的轴向方向与触控屏所在的平面之间的角度θ为90度时，即图5中的θ 0，所述摆动件处于自然下垂状态，所述摆动件的延伸方向与所述主动笔的轴向方向平行，所述摆动件远离所述固定座的一端处于所述半球体30的球面的最低处，且所述摆动件远离所述固定座的一端位于所述半球体30的球心与 笔尖20的连线上，此时，所述信号接收模块与笔尖20内的所述信号发射模块之间的距离L 0最短，所述信号接收模块接收到的所述第一信号的强度S 0是最强的；所述主动笔本体10倾斜时，即所述主动笔本体10的轴向方向与触控屏所在的平面之间的角度θ小于90度时，即图5中的θ 1，所述摆动件随着所述主动笔本体10的倾斜而从所述半球体30的球面的最低处滑动至所述半球体30的球面的第一位置，此时，所述摆动件远离所述固定座的一端的所述信号接收模块与笔尖20内的所述信号发射模块之间的距离L 1>L 0，所述信号接收模块接收到的所述第一信号的强度S 1<S 0，因此，所述处理模块可以根据所述信号接收模块接收的所述第一信号的强度获得所述主动笔本体10的倾斜角度。
需要说明的是，所述摆动件随着所述主动笔本体10的倾斜，在所述半球内的球面上滑动，是随着所述主动笔本体10的倾斜方向移动的，所述主动笔本体10在任意方向倾斜，则所述摆动件可随之沿着任意方向在所述半球体30的球面上移动，且所述摆动件是以所述半球体30的球面的最低处(即所述球面位于所述半球体30的圆心与笔尖20的连线上的点)、为中心进行的、对称的钟摆运动，以保证所述主动笔本体10沿任意方向倾斜相同的角度，所述信号接收模块与所述信号发射模块之间的距离是相同的，所述信号接收模块接收到的所述第一信号的强度是相同的，提高倾斜角度检测的精确度。
需要说明的是，所述半球体30与所述主动笔本体10之间可以是一体成型的一整体结构，也可以是分体结构，所述半球体30与所述主动笔本体10为分体结构时，所述半球体30与所述主动笔本体10通过粘结胶粘接等连接方式连接固定在一起，在此不做限定。
需要说明的是，所述半球体30、所述摆动组件的材质的选择可以有多种，但是需要避免与所述主动笔的触控检测产生电磁干扰，所述半球体30、所述摆动组件采用绝缘的、不会产生电磁感应的材质制成，例如石英。
所述摆动件的具体结构形式可以有多种，本实施例中，所述摆动件包括第一球体40、第二球体50和位于所述第一球体40和所述第二球体50之间的连接杆60，所述第一球体40连接于所述固定座上，所述第二球体50内固定设置有所述信号接收模块，所述第二球体50的外表面与所述半球体30的 内表面接触，如图5-图7所示。
所述信号接收模块固定于所述第二球体50内，相对于所述第二球体50是静止不动的，减少倾斜角度检测的误差。
本实施例中，所述主动笔本体10垂直于触控屏时，所述第一球体40的中心与所述第二球体50的中心的连线与所述主动笔的轴向方向相平行，所述半球体30的球面对所述第二球体50施加的力为零。
所述第二球体50与所述半球体30的球面接触，但是两者之间是无压力接触，即所述主动笔本体10垂直于触控屏时，所述半球体30的球面对所述第二球体50施加的力为零，所述第二球体50依靠自身的重力自然下垂，在所述主动笔本体10倾斜时，所述第二球体50随之在所述半球体30的球面上滑动到相对应的位置，并通过二者之间的摩擦力，使得所述第二球体50固定在相对应的位置，防止其摆动导致无法进行倾斜角度的检测。
所述固定座的具体结构形式可以有多种，所述固定座与所述摆动件之间的连接关系也可以有多种，本实施例中，所述固定座包括具有开口的空心球体，所述开口正对笔尖20设置，所述第一球体40活动连接于所述空心球体内，且所述开口在所述主动笔本体10的径向方向上的最大直径小于所述第一球体40的直径。
在制作时，首先提供形成所述空心球体的两个半球形壳，将所述第一球体40容纳于所述两个半球壳之间，然后将两个半球壳固定连接在一起，以将所述第一球体40容纳于所述空心球体内，所述第一球体40的体积小于所述空心球体的容积，以便所述第一球体40在所述空心球体内转动。
所述开口正对笔尖20设置，使得所述主动笔本体10垂直于触控屏所在的平面时，所述第二球体50能够处于自然下垂状态，使得所述第二球体50内的所述信号接收模块与笔尖20内的所述信号发射模块之间的距离最短，即L0。
所述开口在所述主动笔本体10的径向方向上的最大直径小于所述第一球体40的直径，防止所述第一球体40从所述开口中脱离出来，并且所述开口在所述主动笔本体10的径向方向上的最大直径要大于一预设值，该预设值至少大于所述连接杆60垂直于其延伸方向的方向上的长度，以使得所述第二 球体50能够在一定范围能进行钟摆运动，所述预设值的设定根据所述主动笔本体10的倾斜角度设定，只要满足所述信号接收模块与所述信号发射模块之间的最大距离对应于所述主动笔倾斜时的最小倾斜角即可。
本实施例中，所述半球体30的内表面为光滑的球面，所述第二球体50的外表面是光滑的球面、以使得所述第二球体50能够在所述半球体30的内表面光滑的移动。
采用上述技术方案，减小所述第二球体50与所述半球体30的球面之间的摩擦力，使得所述第二球体50可以顺利的在所述球面上滑动，避免由于摩擦力过大、或者所述球面凹凸不平造成的，倾斜角度检测不准确。
本实施例中，设定所述主动笔本体10的倾斜角度θ对应的n阶θ 0，θ 1，θ 2，θ 3……θ n，并设定与之一一对应的所述信号接收模块接收到的所述第一信号的强度为S 0，S 1，S 2，S 3……S n，所述处理模块还用于根据接收到的所述第一信号的强度使得笔尖20呈与相应的倾斜角度匹配的形态。
图8表示出了倾斜角与第一信号的信号强度的关系，当所述主动笔本体10处于竖直状态时，即所述主动笔本体10垂直于触控屏所在的平面时，所述信号接收模块与所述信号发射模块之间的距离为L 0，此时，所述信号接收模块接收到的信号强度为S 0，当所述主动笔本体10倾斜时，所述信号接收模块与所述信号发射模块之间的距离为L 1，由图5-图7可知L 1>L 0，此时，所述信号接收模块接收到的信号强度为S 1，S 1<S 0。由此可得，所述主动笔本体10越倾斜，倾斜角θ(0～90°)越小，所述信号接收模块与笔尖20内的所述信号发射模块之间的距离L则越大，所述信号接收模块接收到的信号强度S则越小，由此可设定所述主动笔本体10的倾斜角θ(90°～0°)对应n阶θ 0，θ 1，θ 2，θ 3……θ n，并设定与之相匹配的所述信号接收模块接收到的信号强度为S 0，S 1，S 2，S 3……S n，所述倾斜检测结构的所述处理模块根据主动笔可根据接收到的所述第一信号的强度S来做出相应的倾角功能，所述倾角功能包括使得笔尖20呈与相应的倾斜角度匹配的形态，如笔锋等。
本公开实施例还提供一种主动笔触控系统，包括触控屏和上述的主动笔。
通过在所述主动笔内设置倾斜角检测结构，使得所述主动笔的信号发射模块发射第一信号，倾斜角检测结构同步接收所述第一信号进行倾斜角的检 测，即将主动笔触控检测和倾斜角检测在同一时序内进行，从而可以将传统时序中倾斜检测占用的时间用于手指触控检测，提高手指触控报点率。
本公开实施例还提供一种触控方法，应用于上述的主动笔触控系统，包括：
主动笔的信号发射模块发送第一信号至触控屏；
触控屏与主动笔的倾斜角检测结构同步接收所述第一信号，触控屏根据获得的所述第一信号获取主动笔与触控屏的接触位置、进行主动笔触控检测，同时，主动笔的倾斜检测结构根据所述第一信号获取主动笔的倾斜角度。
本实施例中，触控屏在每一帧中交替进行图像显示和触控检测，所述触控检测包括主动笔触控检测和手指触控检测。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
