Description

手写笔和手写输入系统 技术领域
本申请涉及电子设备领域，尤其涉及一种手写笔和手写输入系统。
背景技术
随着科技发展的不断进步，采用手写屏的电子设备越来越多地进入市场，如手写板、智能手机、平板电脑等,可全方位地满足人们的需求。如：集成有手写屏的平板电脑，已不再采用传统的键盘输入，在使用时，用户通过手写笔在手写屏上输入文字(或图形)后，输入的文字(或图形)就可直接显示在平板电脑的显示界面上。
然而，现有技术中的手写笔通常是没设置笔芯，故此，该手写笔不能同时在纸张和手写板或手写屏上进行书写。设有笔芯的手写笔往往是在笔芯无法在纸张上进行笔墨书写时才知道笔芯没笔墨了，需要更换笔芯。如此，降低了手写笔的用户体验。

图3是本申请另一实施方式的手写笔的结构示意图。
具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
请参阅图1和图2，本申请实施方式提供一种手写笔100和手写输入系统1000。手写输入系统1000包括手写笔100和手写设备200。
手写笔100包括壳体110、笔芯120、发光单元130、接收单元140、处理器150和显示单元160。笔芯120、发光单元130、接收单元140和处理器150均设置于壳体110内。笔芯120内存储有用于书写真实字迹的流体，该流体由特定的材料制成例如油墨。手写笔100还包括笔尖121，笔尖121自壳体110的一端伸出，笔尖121与笔芯120连通，用于将流体从笔芯120导出，并在书写纸上形成真实的书写笔迹。笔芯120与笔尖121可以分体成型也可一体成型，在此不做限制。当笔芯中的流体或笔芯本身使用完毕之后，可以更换新的笔芯120，或者是对笔芯120重新注入流体。
发光单元130与接收单元140分别位于笔芯120正对的两侧。具体地，发光单元130可以位于笔芯120的一侧用于发射照射笔芯120的光线，接收单元140位于笔芯120的另一侧，用于接收发光单元130发射的光线照射笔芯120后的出射光，并根据所接收到的出射光的光量生成与所述光量相对应的感应信号。
处理器150与接收单元140连接，通过检测接收单元140的感应信号判断笔芯120内流体的余量。
显示单元160与处理器150电连接并收处理器150的控制，用于对处理器150判断出的笔芯120中的流体的余量进行显示。显示单元160可以是柔性显示单元160，该柔性显示单元贴覆于壳体110上。
当然，手写笔100的壳体110还可开设用于容纳显示单元160的容纳槽。该容纳槽可为通槽。
如此，借助显示单元160所显示的余量，用户可以直观快速的获知笔芯120中流体的余量状态，并根据实际书写需求对笔芯120进行相关处理，例如可以选择继续使用当前笔芯或更换新的笔芯。
本申请实施方式的手写笔100通过在笔芯120正对的两侧分别设置发光单元130与接收单元140，通过接收单元140感测发光单元130发射的光线经过笔芯120后的光量以对笔芯120中的流体的余量进行检测。该手写笔100结构简易，方便用户及时了解余量信息，以根据书写内容及时更换笔芯，用户体验较佳。
本申请的手写笔100适配于手写装置200，其中笔尖121与处理器150电连接，手写笔100在书写时，笔尖121在形成真实笔迹的同时驱动手写装置200产生触控信号，并根据触控信号生成与真实笔迹对应的笔迹信号。该手写装置200为手写板。
手写笔100可包括压力传感器170，压力传感器170与处理器150连接。压力传感器170可与笔芯120同轴设置。在一些示例中，压力传感器170可以设置在笔芯120远离笔尖121的一侧，并固定在壳体110中，当使用手写笔100进行书写时笔尖121抵触在书写纸上，压力传感器170可感测笔尖121受到的压力。在另一些示例中，压力传感器170可套设在笔尖121上，压力传感器170可以呈环状，并夹持与壳体100的内侧壁与笔芯120之间。压力传感器170用于在手写笔书写时感测笔尖121受到的触控压力并生成压力数据，将压力数据发送至处理器150。处理器150将压力数据发送至手写装置200，手写装置200将笔迹信号与压力数据结合生成与真实笔迹对应的三维笔迹，该三维笔迹不仅包含在二维平面的笔迹还包括压力数据。
手写装置200可以包括电容式手写板，电容式手写板可以与手写笔100之间形成耦合电容，进而可以根据耦合电容的变化生成触控信号，进而手写装置200可以根据触控信号生成笔迹信号。
在实际操作中，可将书写纸覆盖于手写装置200上，可以使用手写笔100在书写纸上进 行书写并形成真实笔迹。同时，手写装置200感测手写笔100的书写操作并生成触控信号，并根据触控信号生成与真实笔迹对应的笔迹信号。在本实施例中，手写装置200可以在间隔至少一张书写纸的距离下感测手写笔100的触控书写操作，从而在书写纸上形成真实笔迹的同时，生成与真实笔迹对应的笔迹信号。
手写输入系统1000可以与电子装置，例如平板电脑、手机等进行通讯连接，手写装置200所生成的与真实笔迹对应的笔迹信号可以发送至电子装置进行显示，从而实现在电子装置的显示屏上实时显示笔迹信号对应的真实笔迹。可以理解的，该手写装置200所生成的与真实笔迹对应的笔迹信号还可存储于手写装置200的存储器内。
在某些实施方式中，接收单元140包括光敏电阻，光敏电阻将所述接收的光转化为阻值，处理器150获取光敏电阻的阻值并根据获取的阻值判断流体的余量。
光敏电阻是利用半导体的光电效应制成的一种电阻器，光敏电阻的阻值随入射光的强弱而发生变化，更具体而言，光敏电阻的阻值变化与光照强度负相关。如此，根据光敏的电阻的这个特性可以进行光量的测量。
在实际操作中，笔芯120可采用透光材料制成，例如透明塑料制成，以使得发光单元130发射的光线可以部分的穿过笔芯120被接收单元120接收。
可以理解地，发光单元130发射的可见光经过不同材质的流体的透射率不同，或者说，光敏电阻接收到可见光的光强根据光线是否流经流体而有所不同。具体地，当流体的余量较小时，射出的光直接透过笔芯射入光敏电阻较多，也即此时光敏电阻接收到的光强较强，光敏电阻的阻值越低；而当流体的余量较多时，射出的光大部分被流体遮挡，使得光敏电阻接收的光的光强较弱，光敏电阻的阻值越高。如此，通过光敏电阻的阻值可以判断流体的余量。
在这样的实施方式中，光敏电阻的阻值随流体余量的减少而减小。如此，当流体从多到少时，光敏电阻接收的光强逐渐增强，其阻值逐渐减小。
当然，在另一些示例中，光敏电阻也可选择随光强的增大而阻值增大的类型，也即是说，光敏电阻的阻值随余量的减少而增大。在此不做限制。
在手写笔100出厂前，可以对笔芯120中的流体余量与光敏电阻的阻值进行多次实验，并建立相应的函数关系，该函数关系可录入手写笔100的存储器中。在实际操作中，处理器150从存储器中获取该函数并根据该函数关系以及检测到的光敏电阻的阻值，计算得到笔芯120中的流体余量。
此外，还可以建立多组流体余量与光敏电阻阻值的对应关系，在实际操作中，根据检测到的光敏电阻的阻值，通过查阅该对应关系得到与当前阻值对应的流体余量。
在某些实施方式中，发光单元130、笔芯120和接收单元位于同一水平面。
具体地，发光单元130和接收单元140分居笔芯120正对的两侧，笔芯120内的流体能够对发射单元130发出的可见光进行有效地遮挡，避免发光单元发发出的光线直接入射至接收单元140。
较佳地，发光元件130和接收单元140的径向截面的面积应当小于或等于笔芯120的径向截面面积。如此，笔芯120内的流体可以充分遮挡发光单元130发射的可见光，从而实现对流体余量的准确检测。
在某些实施方式中，处理器150还用于控制发光单元130间隔预定时间发射可见光照射笔芯120。
在实际操作过程中，在笔芯120使用初期，笔芯120中的流体余量较多。无需对笔芯120余量进行频繁检测。同时，由于手写笔100需要通过供电电源对处理器150、发光单元130等元件进行供电，频繁的点亮发光单元130也会增加功耗。因此，可以每隔预定时间控制发光单元130发光照射笔芯120，预定时间可以设置为10小时、24小时等较长的时间间隔。
随着流体的余量逐渐减少，检测的间隔时间可以逐渐缩短从而提高检测频次，以对流体的余量进行及时的检测。例如，可以由24小时逐渐缩短为12小时、6小时等，在此不做限制。
在另一些示例中，手写笔还可以包括输入单元，用于接收用户的输入。发光单元130可以根据用户的输入而触发进行点亮以发射光线对笔芯120进行照射，如此，用户拥有更高的自主性，可以根据需求随时对笔芯120进行检测。输入单元可以是带有触控功能的柔性显示屏，也即是说，显示单元160在显示的同时具有触控功能，可以用于接收的输入。此外，还可单独设置输入单元，例如机械按键等，在此不做限制。
在某些实施方式中，发光单元130包括条形光源。
可以理解，由于手写笔100内部空间狭长，采用条形光源可以充分利用手写笔100的内部空间，同时，由于笔芯120基本呈细长的圆柱状，采用条形光源可以更好的对笔芯120进行照射。条形光源可以由多个LED灯沿长度方向均匀排列组成。
在某些实施方式中，发光单元130、笔芯120和接收单元140的长度相等。
如此，可以对笔芯120中的流体的余量状态在全部使用过程中进行检测。
请参阅图3，在另外一些实施方式中，发光单元130和接收单元140的长度相等，并均小于笔芯120的长度，发光单元130和接收单元140均设置在壳体110靠近书写端的位置处。
可以理解地，在笔芯120中的流体的余量大于某一容积值时，用户可以安心进行书写而无需考虑对笔芯120进行更换，例如余量大于50％，此时，对余量的检测在一定程度上意义较小，或者说，在余量较少时，余量信息对于用户更为重要。设置在靠近书写端也即是笔尖121的位置，可以对流体余量始终进行有效检测。当发光单元130的长度小于笔芯120长度时，流体的液面高度高于或等于发光单元130，接收单元140例如光敏电阻的阻值基本保持不变；当流体的液面高度低于发光单元130时，可以对流体的余量进行有效检测。同时，由于发光单元130的长度较短，在一定程度上可以降低功耗。
在某些实施方式中，显示单元160通过数字或图形显示流体的余量。
具体地，笔芯120流体的余量若以实际的容积展现给用户，将不够直观，用户可能无法对余量进行正确的感知。因此，可以以百分比的形式对余量进行展示，例如可以将全新的笔芯120中的流体的容积记为100％并进行显示，随着流体余量的减少，百分比数字逐渐降低。
在使用过程中，手写笔100可以根据用户实际书写情况对每消耗1％的流体所书写的字数或书写时间进行统计，在对流体余量进行显示的同时，对剩余流体的书写能力进行提示。例如，当消耗1％流体时，记录用户书写1000字，书写10个小时，则根据该书写字数和书写时间，提示用户根据当前书写状态，余量可书写99000字，可继续书写990小时。较佳地，提示信息可以在书写过程中动态调整，也即是每消耗1％重新统计以当前书写状态余量的书写能力。如此，可方便用户掌控笔芯120中流体的余量。
此外，还可通过图形的方式对余量进行显示。例如可以条形图、饼状图等方式进行显示，在此不做限制。
在某些实施方式中，手写笔100还包括提醒单元180。提醒单元180用于在流体的余量小于预定阈值时产生提醒信号。
提醒单元180可以是指示灯、蜂鸣器等元件，提醒单元180与处理器150连接，当处理器150根据接收单元140输出的感应信号判断出笔芯120中的流体余量较少时，可以发出提示信号提醒用户。在一些示例中，当提醒单元180采用指示灯时，可以根据流体余量的由多至少，发出颜色不同的提醒信号。例如，当余量大于60％时，指示灯可以发出绿色提醒信号。当流体余量在30％-60％时，指示灯可以发出橙色提醒信号。而当流体余量小于30％时，指示灯可以发出红色提醒信号。
此外，当显示单元160采用彩色显示单元时，也可以根据流体余量的多少采用不同颜色的图形对余量进行显示。在此不再赘述。
以上所揭露的仅为本申请的较佳实施例而已，当然不能以此来限定本申请之权利范围， 本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本申请权利要求所作的等同变化，仍属于本申请所涵盖的范围。
