请结合参考图1和图2，在本发明的一实施例中，该智能笔包括笔杆10、笔芯30以及导向结构50。其中，笔杆10设有触碰开关11；笔芯30可移动地设于笔杆10，笔芯30相对笔杆10移动可抵接触发触碰开关11，笔芯30的长度不小于70㎜，且不大于150㎜；导向结构50设于笔杆10，以对笔芯30的移动进行导向。
在本发明的一实施例中，笔杆10主要用于安装和承载笔芯30和导向结 构50等，其于水平面上的投影可以为圆形结构，以便于用户对其进行握持。为了延长笔杆10的使用年限，笔杆10的材质可以为金属材质，例如：铝质材料，铝合金材料、铜质材料、铜合金材料、铁质材料、不锈钢材料等；当然，为了降低笔杆10的重量，笔杆10的材质也可以为塑料材质，例如：ABS、POM、PS、PMMA、PC、PET等。而触碰开关11主要用于对智能笔的工作状态进行感应，以触发智能笔上与该触碰开关11电性连接的摄像头进行工作。具体而言，在智能笔进行书写或者绘图时，即处于工作状态时，笔芯30受到显示屏、触摸屏或者纸张的挤压压力而发生移动，并处于工作状态。此时，笔芯30抵接于触碰开关11并触发触碰开关11工作，使得摄像头获取该触发信号后即可开启而对输入信息进行正常的捕获工作。笔芯30主要用于在显示屏、触摸屏或者纸张上进行书写或者绘图，其中，当其在显示屏或者触摸屏上进行书写或者绘图时，该笔芯30可以为塑胶笔芯30；当其在纸板上进行书写或者绘图时，该笔芯30可以为无碳笔芯30或者白板墨水笔芯30，本申请对此不作限定，能够保证该智能笔可以在显示屏和/或触摸屏和/或纸张上进行书写或者绘图即可。导向结构50主要用于对笔芯30的移动进行导向，保证其在移动过程中的平稳性。
本发明的技术方案的智能笔在显示屏、触摸屏或者纸张上进行书写或者绘图时，由于笔芯30可移动地设于笔杆10，使得笔芯30在受到显示屏、触摸屏或者纸张的挤压压力而发生移动。并在该笔芯30移动一定的距离后，可以抵接触发触碰开关11，以使得智能笔上与该触碰开关11电性连接的摄像头开启，从而完成了智能笔对其在显示屏、触摸屏或者纸张上的输入信息的获取。由于本方案中的智能笔于笔杆10上还设置有导向结构50，通过该导向结构50可以对笔芯30的移动进行导向。如此避免了笔芯30在移动过程中发生偏移，使得笔芯30在移动过程中较为平稳而能够准确的抵接触发触碰开关11，从而提高了笔芯30和触碰开关11接触的均匀、稳定性，保证了智能笔的正常工作。另外，笔芯30的长度不小于70㎜，避免了由于笔芯30的长度过小而影响笔芯30内部对墨水的容量；且笔芯30的长度不大于150㎜，则避免了由于笔芯30的长度过大而影响笔芯30在进行书写的移动过程的稳定性。进一步地，该类笔芯30的长度相较于现有技术中的智能笔的笔芯30的长度更长，如此能够容纳更多的墨水而便于持久书写，减少更换笔芯30的次数， 从而能够提高智能笔使用的便利性。而且，该类笔芯30的长度在非智能笔的市场上使用的较多，例如：中心笔芯，如此能够使得该类笔芯30容易购买以便进行更换，从而能够进一步地提高智能笔使用的便利性。更进一步地，笔芯30的直径可以设置为不小于2㎜，且不大于6㎜。
请参考图2，在本发明的一实施例中，导向结构50包括导向腔50a，导向腔50a设于笔杆10，并沿笔芯30的移动方向延伸设置；笔芯30包括笔芯本体31和连接于笔芯本体31的笔尖33，笔芯本体31至少部分可移动地嵌设于导向腔50a内，笔芯本体31远离笔尖33的一端可抵接触发触碰开关11，笔尖33由导向腔50a穿出而显露于外界。
可以理解，由于导向腔50a沿笔芯30的移动方向延伸设置，使得笔芯30在移动过程仅沿导向腔50a的延伸方向进行移动，从而避免了笔芯30在移动过程中发生偏移。而且，笔芯本体31至少部分嵌设于导向腔50a内，也可以使得笔芯30和笔杆10可以分布的更为紧凑，如此减小了智能笔的整体体积而使其便于用户握持。同时，通过该保护腔对笔芯本体31也具有一定的保护作用，避免其由于大部分裸露在外而容易受到损坏。进一步地，为了避免笔尖33容易与外物发生碰撞而受到损坏，智能笔还可以包括笔套，该笔套套设于笔杆10的外侧，而笔尖33容置于笔套内。如此在智能笔需要进行书写或者绘图时，将笔套从笔杆10上拔出即可使得笔尖33显露于外界；在智能笔需要进行存放时，将笔套套设于笔杆10即可使得笔尖33容置于笔套内。其中，笔套与笔杆10可以为卡接固定，具体而言，笔套内笔设有卡扣，笔杆10外壁设有卡槽，卡扣卡入卡槽内，使笔套固定于笔杆10。当然，笔套与笔杆10也可以为磁吸固定，具体而言，笔套内壁设有第一磁铁，笔杆10外壁设有第二磁铁，第二磁铁与第一磁铁相吸附而使得笔套固定于笔杆10。可以理解，如此设置，便于笔套的插拔与套设，从而提高了智能笔使用的便利性。需要说明的是，本申请不限于此，于其他实施例中，导向结构50也可以是滑块和滑槽的配合。具体而言，笔芯本体31设有滑块和滑槽的其中之一，笔杆10设有滑块和滑槽的其中之另一，滑槽沿笔芯本体31的移动方向延伸设置，滑块滑动连接于滑槽内。
在本发明的一实施例中，导向结构50还包括导向套51，导向套51设于导向腔50a内，并套于笔芯本体31的外表面。
可以理解，通过导向套51套设于笔芯本体31的外表面，进一步地对笔芯30在非平行于笔芯30的移动方向上进行限位，从而进一步地提高了导向组件对笔芯30的移动过程的导向效果。同时，导向套51的设置也避免了笔芯30在移动过程中与导向腔50a的腔壁发生直接的磨损而影响笔杆10的使用年限，而导向套51相对于笔杆10更方便制造，从而降低了智能笔因为磨损而需要维修或者更换的复杂度。进一步地为了减少笔芯30在移动过程对导套所造成的磨损，导向套51可以选用耐磨性较好的材质，例如钢或者合金等。
在本发明的一实施例中，导向套51抵接于导向腔50a的腔壁，笔杆10和笔芯30相配合夹持固定导向套51。
可以理解，通过笔杆10和笔芯30的夹持固定导向套51，简化了导向套51的固定结构，从而降低了智能笔的制造成本，同时也提高了智能笔的组装效率。其中，笔杆10可以是在其端面设有开口，以便导向套51从该端面开口插入导向腔50a内；当然也可以是在其侧周面设有开口，以便导向套51从该侧周面面开口嵌入导向腔50a内，本申请对此不作限定。
在本发明的一实施例中，导向套51设有止转块和止转槽的其中之一，导向腔50a的腔壁设有止转块和止转槽的其中之一，止转块插入止转槽内。
可以理解，通过止转块和止转槽的配合限位作用，避免了导向套51在笔芯30的移动过程中发生旋转而影响笔芯30的移动以及笔芯30与触碰开关11的均匀抵接，从而进一步地保证了笔芯30在移动过程中较为平稳而能够准确的抵接触发触碰开关11，以提高笔芯30和触碰开关11接触的均匀、稳定性，确保智能笔的正常工作。
在本发明的一实施例中，导向套51设有至少两个止转块，至少两个止转块沿导向套51的周向呈均匀间隔分布，导向腔50a的腔壁设有至少两个止转槽，一个止转槽与一个止转块呈相对设置，每一个止转块插入与该止转块相对应的止转槽内。
可以理解，至少两个止转块和止转槽的设置增大对导向套51的止转效果，进一步地避免导向套51在笔芯30的移动过程中发生相对转动。而至少两个止转块沿导向套51的周向呈均匀间隔分布，则保证了导向套51的各处所受到的止转力均匀分布，避免了因受力不均造成应力集中而对导向套51造成损坏。另外，止转块设于导向套51，则避免了因为止转结构的设置对导向套51 的强度造成影响，从而保证了导向套51的使用年限。
在本发明的一实施例中，在导向套51的周向方向上，导向套51呈环形一体结构设置，或者呈多块拼接的分体结构设置。
可以理解，导向套51呈环形一体结构设置便于导向套51的成型，从而能够提高导向套51的生产效率；同时也便于导向套51的安装，从而能够提高智能笔的组装效率。而导向套51呈多块拼接的分体结构设置时，则使得导向套51的局部发生损坏时，可以对该块拼接体进行维修更换，避免了局部损坏而需要对整体进行维修更换，从而降低了导向套51的维修更换成本。同时，多块拼接体可以间隔分布而形成导向套51，如此减少了生产材料的使用，从而降低了导向套51的制造成本。
请结合参考图2和图3，在本发明的一实施例中，触碰开关11具有触碰端111，触碰端111嵌设于导向腔50a内，笔芯本体31远离笔尖33的一端可抵接于触碰端111。
可以理解，触碰端111嵌设于导向腔50a内，使得笔芯本体31与触碰端111相接触的一端在移动过程中始终位于导向腔50a内，保证两者在接触触发时仍然受到导向组件的导向的作用，从而进一步地提高了笔芯本体31和触碰开关11在接触时抵接的稳定性。同时，将触碰端111嵌设于导向腔50a内也可以避免该端由于裸露在外而容易受到损坏，从而延长了触碰开关11的使用年限。
在本发明的一实施例中，触碰端111至少部分插入导向套51内，并抵接于导向套51的内表面。
可以理解，如此设置使得导向套51对触碰端111也具有限位作用，使得笔芯本体31与触碰端111相接触时能够更加的稳定，避免两者于非平行于导向套51的延伸方向上发生移动，以进一步地确保笔芯本体31和触碰开关11在接触时抵接的稳定性。
在本发明的一实施例中，定义笔芯本体31和触碰端111之间的距离为D，0㎜＜D≤0.5㎜。
可以理解，当笔芯本体31和触碰端111之间的距离D＞0.5㎜，容易由于笔芯30的移动行程较大而使得用户在对其使用书写或者绘图时不流畅，导致影响了该智能笔使用的便利性，因此，将笔芯本体31和触碰端111之间的距 离D设置为0㎜＜D≤0.5㎜，可以确保该智能笔使用时较为顺畅而方便书写或者绘图。其中，笔芯本体31和触碰端111之间的距离D可以为：0.1㎜、0.2㎜、0.3㎜、0.4㎜、0.5㎜等，当然也可以是以上区间的任意取值，本申请对笔芯本体31和触碰端111之间的距离D的具体值不作限定，能够保证笔芯30书写或者绘图时较为流畅即可。
以上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。
