笔芯30包括针管和笔头，针管设于安装腔10a内，并朝向位于其上端的感应器21延伸，笔头连接于针管背离感应器21的端部，即笔头位于安装腔10a的下端，且部分由笔盖50的避让孔50a向外部伸出。
本发明的智能笔100在书写时，笔头受到来自于书写对象的压力作用，即沿竖直方向向上运动，针管背离笔头的端部抵顶于位于其上方的感应器21，感应器21被触发后，向摄像头22发送电信号，摄像头22接收到电信号后，同步采集和识别用户在书写对象上书写的文字、符号或是图像，并将其转化为电子文档朝向存储，如此即可实现用户在书写时的同步录入，较大程度的提高了办公的效率。
在一实施例中。笔盖50可拆卸的盖合于安装腔10a的开口端，笔芯30的部分容置于安装腔10a内，且部分容置于安装腔10a内的笔芯30可抵接于安装腔10a的腔壁面和笔盖50，即通过笔盖50和笔架10将笔芯30限位固定于安装腔10a内，笔芯30的其余部分由笔盖50上开设的避让孔50a向外部伸出，以供用户进行书写。本发明中通过笔盖50盖合于笔架10，使得笔芯30的部分可限位固定于安装腔10a内，从而方便用户进行书写，而当需要更换笔芯30时只需要将笔盖50从笔架10上拆除，打开安装腔10a，即可实现笔芯30的更换，整个操作过程简单方便，并且不会造成笔芯30或是笔架10的损坏，从而提高智能笔100的使用寿命。
在本发明的一实施例中，所述笔架10和所述笔盖50两者的其中之一设有内螺纹，两者的其中之另一设有外螺纹，所述笔架10和所述笔盖50螺纹连接。
具体而言，在本发明的一实施例中，笔架10包括架本体11和连接于其架本体11下端的连接镶件12，架本体11由塑胶材料或是金属材料成型，架本体11开设有上述的安装腔10a，安装腔10a的开口朝向架本体11的下端。连接镶件12连接于架本体11的下端，并邻近于安装腔10a的开口端。连接镶件12背离架本体11一侧的表面设有若干内螺纹，笔盖50的内侧设有与其相 适配的外螺纹，笔盖50通过螺纹可拆卸连接于架本体11，用于打开或是关闭该安装腔10a。当需要更换笔芯30时，只需要沿顺时针或是逆时针转动笔盖50即可将笔盖50和连接镶件12相分离，以此打开安装腔10a，并将旧笔芯30从安装腔10a内取出；更换新笔芯30后，再将笔盖50沿顺时针或是逆时针连接于连接镶件12，以关闭安装腔10a，如此即可完成笔芯30的更换，笔芯30整个更换过程的操作简单方便。同时，本申请的一实施例中，该连接镶件12由金属材料制成，例如：不锈钢、铜或是铝合金等材料。如此笔盖50可以更多次数的反复旋合于连接镶件12，而连接镶件12上的螺纹不至于损坏或是滑牙，从而较大程度的提高了智能笔100的使用性能和使用寿命。
可以理解的是，笔盖50和连接镶件12也可以采用其它形式的可拆卸连接结构，例如，在本发明的另一些实施例中，连接镶件12的外侧面设有卡扣，笔盖50上设有卡孔。卡扣扣合于卡孔内，将笔盖50连接固定于连接镶件12，如此笔芯30的更换操作也较为方便。在其它的一些实施例中，连接镶件12和笔盖50采集插接或是磁性吸合的方式可拆卸连接，在此不做详细赘述。
请结合参见图5，为了使得连接镶件12和架本体11的连接更为稳固和紧密。在本发明的一实施例中，连接镶件12的外侧面通过机械切削形成卡槽12a，安装腔10a的腔侧壁对应于该卡槽12a朝向安装腔10a的内侧凸设形成卡凸111，当连接镶件12连接于架本体11时，该卡凸111卡接于该卡槽12a内。本申请中通过卡凸111卡拉于卡槽12a内，如此当连接镶件12和架本体11通过模内注塑成型后，两者之间的连接更为稳固，从而避免了在书写的过程中连接镶件12脱落，影响智能笔100的书写和使用。
在本发明的一实施例中，所述笔芯30的下部沿周向凸设形成有止挡凸缘31。具体地，该止挡凸缘31设于针管和笔头之间，并沿笔芯30的周向边缘设置，笔盖50背离避让孔50a一侧的表面设有一台阶面。当笔芯30容置于安装腔10a内时，笔头的部分由避让孔50a伸出，止挡凸缘31抵接于笔盖50的台阶面，在书写时，笔头受到来自于书写平面向上的作用力，并向上运动，此时止挡凸缘31的上表面抵接于连接镶件12的下表面，即通过设置该止挡凸缘31使得笔芯30于连接镶件12的下表面和笔盖50的台阶面往复运动，从而避免笔芯30的笔头在书写时收缩至安装腔10a内，从而影响书写。
可以理解的是，市售的中性笔芯30一般而言都具有该止挡凸缘31，因此 本申请通过设置上述限位固定结构使得智能笔100可以使用市售的通用水性笔芯30，因而不必采用专门定制笔芯30，从而提高了智能笔100的互换性和通用性，较大程度了方便了用户的使用。
请结合参见图6，在本发明的一实施例中，所述智能笔100还包括限位组件40，该限位组件40设于安装腔10a内，用以将位于安装腔10a内的部分笔芯30进行限位。
具体地，该限位组件40包括弹簧和限位套管41，该限位套管41呈管状设置，并于安装腔10a内沿笔架10的长度方向上延伸设置，限位套管41内管的管径略大于笔芯30针管的管径，从而使得针管可以套设于限位套管41内。当针管套接于限位套管41内时，笔芯30的止挡凸缘31可抵接于限位套管41的下端。本申请中，弹性件42为弹簧，当然该弹性件42也可以是由硅橡胶制成的弹性垫块，在此不做具体限定。该弹簧套设于限位套管41的上端，并弹性抵接于安装腔10a的腔侧壁，在弹簧弹力的作用下，限位套管41的下端抵顶于止挡凸缘31的上表面，并将笔芯30整体朝向安装腔10a的开口端抵顶。图像感应组件的感应器21设于限位套管41的上端。
本申请中，笔芯30套设于限位套管41内，通过限位套管41的限位导向作用，使得笔芯30在安装腔10a内往复运动时，其运动的轨迹不会发生较大的偏离或是较大的偏摆，从而降低了书写的过程中笔芯30发生晃动幅度，提高了用户书写的体验度。进一步地，弹簧套接于限位套管41的上端，在弹簧提供弹力的作用下，可使得止挡凸缘31的下表面牢牢抵接于笔盖50的台阶面上从而避免笔芯30在使用的过程中产生晃动，并且通过弹簧的弹力作用消除笔芯30和笔架10之间的间隙配合公差，使得笔芯30和笔架10牢牢贴合，如此则更进一步地避免了在书写的过程中笔芯30产生晃动，从而提高用户的体验度。
请再次参见图6，为了方便弹簧的拆装，本发明的一实施例中，限位组件40还包括可拆卸连接的限位套管41和限位堵头43。其中，限位堵头43的整体呈圆柱形延伸设置，一端插接于限位套管41内，限位堵头43背离限位套管41一侧的表面朝向感应器21一侧凸伸形成限位凸起，弹簧套接于该限位凸起，弹簧的一端抵接于限位堵头43，另一端抵接于安装腔10a的腔侧壁。需要说明的是，本申请中感应器21粘接于安装腔10a的腔底壁，安装腔10a 底壁环绕感应器21的周向凸设形成凸起。在书写的时，笔芯30抵接于限位套管41，限位套管41将限位堵头43朝向感应器21一侧抵顶，弹簧抵接于感应器21周向的凸起，限位凸起继续朝向感应器21一侧运动，并最终抵顶和触发感应器21。本申请中，弹簧通过限位凸起套接于限位堵头43上。如此限位组件40的结构较为简单，并且弹簧的拆装操作也较为方便。
在本发明的一实施例中，图像采集组件还包括滤光片23，具体地，该滤光片23设于安装腔10a内，并位于摄像头22的下方。摄像头22通过该滤光片23采集书写平面上的文字、符号以及图像。可以理解的是，滤光片23可以吸收特定波长的光线，因此通过设置该滤光片23，可使得摄像头22采集到的文字和符号更为清晰，以此提高摄像头22识别文字和符号的准确性。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
