在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
本发明实施例提供的一种笔体弹出结构，参照图1、图2所示，包括：笔杆1，笔杆1的顶部1-2安装有笔尾帽2。笔尾帽2上连接有伸入笔杆1内的卡勾6。
可选地，卡勾6可以从笔尾帽2的内表面向外伸出。卡勾6沿着平行于笔杆1的轴线的方向延伸，卡勾6的末端形成有勾取部6-1，勾取部6-1使得卡勾6能够勾挂在特定结构上。笔尾帽2以及其上连接的卡勾6能够沿着笔杆1的轴向a移动。
配合参阅图3，笔体弹出结构还包括滑槽机构4，滑槽机构4设置在笔杆1内。在滑槽机构4上设置有滑动引导部4-8和卡槽4-6，滑动引导 部4-8被配置为能够引导卡勾6向下移动，滑入并卡在卡槽4-6内，实现与卡槽4-6的卡合；并且，还能够引导卡勾6从卡槽4-6中脱离，实现与卡槽4-6的分离并使卡勾6顺利复位。
进一步地，笔体弹出结构还包括有弹性件3，弹性件3被配置为用于对笔尾帽2施加弹性作用力，该弹性作用力的方向是沿着从笔杆1的底部1-3向顶部1-2的方向。弹性件3可以设置在笔杆1内。通过弹性件3的作用，笔尾帽2和卡勾6能够在不受到限位限制时，沿着笔杆1的底部1-3向顶部1-2的方向移动。
配合参阅图4，简单描述本发明提供的笔体弹出结构的动作原理，如下：首先，笔尾帽2位于原始/复位状态，对应卡勾6位于原始/复位状态位置A，两者由笔杆1的顶部1-2向底部1-3的方向运动时，滑动引导部4-8对卡勾6施加作用力，使卡勾6发生弹性形变，进而使卡勾6能够滑入或弹入卡槽4-6内。此时，笔尾帽2收缩在笔杆1中，对应卡勾6位于卡合位置B，上述动作过程为笔尾帽2向笔杆1内运动实现卡合固定的过程。
进一步地，使笔尾帽2和位于卡合位置B的卡勾6向下移动时，卡槽4-6和滑动引导部4-8能够配合引导卡勾6从卡槽4-6中脱出，使卡勾6从卡合位置B返回到原始/复位状态位置A，此时笔尾帽2对应回到原始/复位状态。在上述的动作过程中，笔尾帽2和卡勾6会沿着由笔杆1的底部1-3向顶部1-2的方向移动。
本发明提供的笔体弹出结构的优点在于，通过滑动引导部和4-8卡槽4-6对卡勾6的引导作用，就可以实现笔尾帽2缩入笔杆1和弹出笔杆1的动作。相对于现有的笔体弹出结构，本发明省去了主动轮、从动轮等旋转传动机构，有效的简化了其中的结构。进一步地，本发明的笔体弹出结构的零部件相对于现有技术明显减少，加工和装配过程都更为简化。
本发明就滑动引导部4-8提供了具体的优选实施方式，具体结合附图进行描述。
可选地，如图3所示，滑动引导部4-8包括第一引导面4-1；进一步地，还可以包括第二引导面4-4。第一引导面4-1用于引导卡勾6与卡槽4-6卡合，第二引导面4-4用于引导卡勾6从卡槽4-6中脱离，实现复位。
具体地，第一引导面4-1从笔杆1的顶部1-2向底部1-3倾斜延伸且沿笔杆1的第一径向r1逐渐远离笔杆1的轴中心，其延伸方向相对于笔杆1的轴向a具有一定倾斜和弯曲。卡槽4-6则位于第一引导面4-1的下方，所述下方为与所述第一径向r1相对的第二径向r2。
在笔尾帽2和卡勾6执行向下移动并使卡勾6卡入卡槽4-6的动作时，配合参阅图2及图4，首先，随着卡勾6向下移动，第一引导面4-1会逐渐推动卡勾6的勾取部6-1，使卡勾6向侧面变形，即向第一径向r1变形，卡勾6自身产生弹性形变作用力，即在第一引导面4-1的作用下，勾取部6-1沿着第一引导面4-1向远离笔杆1的轴中心移动，即向第一径向r1移动，使卡勾6产生了靠近所述轴中心的回复力，即朝向第二径向r2的回复力。然后，当卡勾6向下移动到越过第一引导面4-1的底端4-1-1时，卡勾6在自身弹性形变作用力的驱动下会向卡槽4-6处移动，进而使勾取部6-1进入并卡合到卡槽4-6中，到达卡合位置B。
继续参阅图3，第二引导面4-4则沿着从笔杆1的顶部1-2向底部1-3的方向，倾斜向下延伸，且沿笔杆1的第三径向r3逐渐远离笔杆1的轴中心，第二引导面4-4与第一引导面4-1优选是以沿着上述方向逐渐远离笔杆1的轴中心的形式延伸。
配合参阅图4，在笔尾帽2和卡勾6执行向下移动并最终使卡勾6回到原始/复位状态位置A的动作时，首先，按压笔尾帽2，使得卡勾6再次向下移动，第二引导面4-4能够引导勾取部6-1在水平(即第三径向r3)及竖直(即笔杆1的轴向a)方向上都远离卡槽4-6的方向移动，进而使得勾取部6-1完全脱离于卡槽4-6的范围。
进一步地，在解除使笔尾帽2向下移动的作用力后，笔尾帽2以及卡勾6会在弹性件3的作用下向上移动，进而使卡勾6返回到原始/复位状态位置A，对应笔尾帽2返回到原始/复位状态。
优选地，滑动引导部4-8还可以包括引导件4-7，如图3所示。引导件4-7位于卡槽4-6的下方相对靠近第一引导面4-1的底端4-1-1，其用于与第一、第二引导面4-1、4-4以及卡槽4-6配合，以提高勾取部6-1卡入、脱离卡槽动作执行的可靠性。引导件4-7上靠近第一引导面4-1的表面为止挡面4-3，止挡面4-3被配置为用于对越过第一引导面4-1的底端4-1-1 的勾取部6-1形成止挡。
具体如图4所示，当勾取部6-1与第一引导面4-1脱离时，由于卡勾6受自身的弹性形变作用力的作用，如果没有止挡面4-3的存在，则勾取部6-1存在向右(即第二径向r2)直接越过卡槽4-6而复位回到原始/复位状态位置A，无法卡在卡槽4-6中的可能性。在这种优选的实施方式中，通过设置止挡面4-3，能够对从第一引导面4-1的底端4-1-1脱离的勾取部6-1形成止挡，进而引导勾取部6-1顺利地卡在卡槽4-6中。
进一步优选地，止挡面4-3的顶端高于第一引导面4-1的底端4-1-1，从而保证止挡面4-3一定能够防止勾取部6-1直接越过卡槽4-6。
可选地，如图3所示，引导件4-7的远离第一引导面4-1的表面作为弹出引导面4-5。弹出引导面4-5被配置为与第二引导面4-4配合，共同引导卡勾6的勾取部6-1从卡槽4-6脱离。弹出引导面4-5沿着从笔杆1的顶部1-2向底部1-3的方向，朝远离第一引导面4-1的底端4-1-1的方向(即第二径向r2)倾斜延伸。
具体如图4所示，在笔尾帽2和卡勾6受到向下移动的作用力而执行卡勾6从卡合位置B返回原始/复位状态位置A时，勾取部6-1与卡槽4-6分离，勾取部6-1沿着第一引导面4-1和弹出引导面4-5的表面，顺势滑至卡槽4-6的右侧(即第二径向r2的一侧)。即，勾取部6-1移动到脱离卡槽4-6的位置。在解除驱使笔尾帽2向下移动的作用力后，笔尾帽2和卡勾6在弹性件3的作用下使卡勾6回到原始/复位状态位置A，对应笔尾帽2返回到原始/复位状态。
进一步优选地，第二引导面4-4和弹出引导面4-5可以是相互垂直的表面，即第一径向r1、第二径向r2这两个方向与第三径向r3相互垂直。这样，两者可以分别从勾取部6-1的正面和侧边对勾取部6-1实现引导作用，确保勾取部6-1能从卡槽4-6中脱离。
可选地，如图3所示，引导件4-7呈尖榫型结构，上述止档面4-3和弹出引导面4-5可以分别位于尖榫型结构的两侧，两个表面沿着从笔杆1的顶部1-2到底部1-3的方向，以相对远离的形式延伸。引导件4-7的尖端朝向卡槽4-6内侧。其中止档面4-3的延伸方向可以与第一引导面4-1的延伸方向基本平行，使勾取部6-1从第一引导面4-1过渡到止档面4-3 上的过程更顺滑，可靠性更高。
可选地，如图3所示，卡槽4-6可以呈倒V型或倒U型结构，卡槽4-6的开口方向朝向笔杆1的底部1-3。这种结构设计更有利于勾取部6-1卡在卡槽4-6中。当勾取部6-1向下运动越过第一引导面4-1的底端4-1-1后，卡槽4-6内表面上的两个侧壁能够对勾取部6-1起到引导作用，提高勾取部6-1准确滑入卡槽的可靠性。
可选地，滑动引导部4-8还可以包括复位引导面4-2，如图3所示，复位引导面4-2位于卡槽4-6的远离第一引导面4-1的一侧(即第二径向r2的一侧)。复位引导面4-2沿平行于笔杆1的轴向a的方向延伸，并且，复位引导面4-2可以相对于第二引导面4-4具有一定倾斜角度，也就是说，复位引导面4-2是沿平行于笔杆1的轴向a方向倾斜延伸，即复位引导面4-2与第二径向r2具有一个非零的夹角4-2-1。由于复位引导面4-2平行于笔杆1的轴向a，因此其能够对勾取部6-1起到更顺畅的引导作用，使所述勾取部6-1沿着笔杆1的轴向a向顶部1-2移动。进一步地，复位引导面4-2具有一定倾斜角度使得卡勾6可以顺畅地释放因变形产生的形变作用力，进而沿着复位引导面4-2复位。
在如图3所示的实施方式中，复位引导面4-2由左向右逐渐向纸面内侧倾斜。第二引导面4-4的末端4-4-1与复位引导面4-2对接。如图4所示，在卡勾6执行返回原始/复位状态位置A的动作时，勾取部6-1会滑动到第二引导面4-4的末端4-4-1，此时复位引导面4-2对勾取部6-1起到引导作用，使勾取部6-1能够平顺地从第二引导面4-4过渡到复位引导面4-2，以更顺利地回到原始/复位状态位置A。
优选地，卡勾6采用具有弹性的金属件。当勾取部6-1沿着第一引导面4-1移动时，勾取部6-1会被第一引导面4-1推动变形，进而向一侧偏斜。此时，卡勾6自身能够产生弹性回复力。这样，当勾取部6-1越过第一引导面4-1的底端4-1-1时，卡勾6的弹性回复力能够使勾取部6-1弹入到所述卡槽4-6中。
进一步地，当勾取部6-1向下沿着第二引导面4-4移动时，所述卡勾6的弹性回复力能够进一步释放，从而驱使勾取部6-1从卡槽4-6中脱离并在弹性回复力的作用下到达复位引导面4-2以实现复位。具有良好弹性 形变能力的卡勾6能够更好地执行上述动作。优选地，卡勾6整体采用金属材料制成，金属耐磨可以延长使用寿命，且金属具有一定的弹性回复力，即卡勾6优选由具有弹性且耐磨的金属件构成。
可选地，如图1所示，笔杆1中还形成有卡止勾1-1，卡止勾1-1位于滑槽机构4的上方。当卡勾6和笔尾帽2位于原始/复位状态时，卡勾6的勾取部6-1能够与卡止勾1-1形成卡接，卡止勾1-1起到限制卡勾6以及笔尾帽2的位置的作用。避免卡勾6和笔尾帽2受到弹性件3的作用力而弹出笔杆1。
可选地，如图1、5所示，本发明的笔体弹出结构还可以包括连接件5。连接件5在该结构中可以起到对各个部件实现相互固定连接、各个机构相互衔接配合的作用。连接件5固定连接在笔杆1的底部1-3，连接件5的上部形成有上端面，该上端面用于与弹性件3形成配合，弹性件3的一端顶在该上端面上，另一端则顶在笔尾帽2的内表面上。当笔尾帽2向下移动时，弹性件3被压缩，并产生弹性作用力。
为了连接连接件5和笔杆1，可选地，参照图1所示，在连接件5的外表面上设置相互平行排列的多个环槽5-1，且在每两个邻近的环槽5-1之间形成凸起部5-2，连接件5的凸起部5-2与笔杆1底部1-3的内表面固接。
在一个具体的例子中，连接件5的外表面上的多个环槽5-1呈等间距且相互平行设置，进一步地，在所有的凸起部5-2的外壁上涂上胶，采用粘结的方式使连接件5与笔杆1紧密的固接在一起。其中，由于凸起部5-2较高，所以在涂胶过程中其上多余的胶会顺着流入两侧的环槽5-1内填充环槽5-1与笔杆之间的空隙，使得连接件5与笔杆1更紧密的固接在一起。
可选地，滑槽机构4可以是直接一体成型在笔杆1的内表面上的结构；或者，滑槽机构4也可以是独立的构件，其通过特定的装置固定设置在笔杆1中。在一种可选的实施方式中，滑槽机构4为独立的构件，可以将其***到笔杆1中与连接件5形成固定连接，从而固定在笔杆1中。
在一个具体的例子中，如图5所示，连接件5通过在外表面上设置有至少两个凸块5-3，实现与滑槽机构4的连接。滑槽机构4上设置有与所述凸块5-3数量相等、位置相对应的凹槽4-9。当滑槽机构4和连接件5 要固定连接在一起时，连接件5外表面上的凸块5-3与滑槽机构4上的凹槽4-9相互插接固定，该插接固定方式为可拆卸地插接固定。
进一步地，如图1、2所示，笔尾帽2上还连接有直杆7。相应地，连接件5的上端面上可以形成有孔5-4。直杆7的一端与笔尾帽2的内端面连接，直杆7的另一端伸入到连接件5的孔5-4内。该直杆7能够对笔尾帽2和卡勾6整体的移动起到引导作用，直杆7的延伸方向平行于笔杆1的轴向a。在直杆7的引导作用下，笔尾帽2和卡勾6能够平顺地沿着笔杆1的轴向a移动，不易发生偏斜。在卡勾6受到作用力而偏斜、变形的情况下，直杆7与上述孔5-4的配合关系对笔尾帽2以及笔杆1之间起到轴向定位的作用，提高各机构之间的配合顺畅程度。另一方面，通过对连接件5上的孔5-4的深度进行设计，可以对笔尾帽2的移动距离进行限位。当直杆7随笔尾帽2向下移动一定距离后，直杆7的端部顶在孔5-4的底部，从而阻止直杆7以及笔尾帽2进一步向下移动。这种设计能够避免笔尾帽2过度伸入到笔杆1中。
进一步可选地，弹性件3可以是弹簧。该弹簧套设在直杆7上，抵接于笔尾帽2的内端面与连接件5的上端面之间。
可选地，为了延长使用寿命，直杆7可采用金属材料制成。
以下配合参照图3及图4所示，对触控笔弹出结构的工作过程进行描述：
第一阶段：压缩阶段；
起初，笔尾帽2处于原始/复位状态，卡勾6位于原始/复位状态位置A，即勾取部6-1与卡止勾1-1卡合(如图1所示)。当笔尾帽2第一次受到按压时，卡勾6由原始/复位状态位置A沿滑槽机构4的第一引导面4-1向下滑动，当卡勾6的勾取部6-1与第一引导面4-1的底端4-1-1脱离后，勾取部6-1会打在止档面4-3上。此时解除按压动作，笔尾帽2和卡勾6在弹性件3的作用下及止挡面4-3的引导下向上移动，使卡勾6到卡合位置B(即卡槽4-6内)，卡勾6的勾取部6-1卡合在卡槽4-6内，实现了压入卡合的过程，此时笔尾帽2大部分位于笔杆1内。
具体地，当第一次按压笔尾帽2后，由于卡勾6在开始阶段沿着第一引导面4-1向下滑动，使卡勾6一直处于偏斜状态，一直存在回弹力，保 证其通过第一引导面4-1后能顺利到达卡合位置B(即卡槽4-6内)，完成压缩阶段的过程。其中，在卡勾6由第一引导面4-1到卡合位置B(即卡槽4-6内)的过程中，止挡件4-3起到了阻止卡勾6因受回弹力的作用使勾取部6-1直接越过卡合位置B(即卡槽4-6内)而复位到原始/复位状态位置A的作用。此处要特别注意的是，当勾取部6-1卡合在卡槽4-6中时，卡勾6仍处于偏斜状态，只是偏斜角度变小，仍存在一定的回弹力。
第二阶段：弹出阶段
经过压缩阶段后，笔尾帽2大部分位于笔杆1内，卡勾6位于卡合位置B，当再次按压笔尾帽2时，卡勾6的勾取部6-1与卡槽4-6分离。在按压笔尾帽2的过程中，卡勾6向下运动，沿着滑槽机构4上的第二引导面4-4以及弹出引导面4-5滑动到复位引导面4-2，在弹性件的弹性作用力下回到原始/复位状态位置A，笔尾帽2对应回到原始/复位状态，完成弹出过程。
具体地，在弹出阶段，向下按压笔尾帽2，卡勾6由卡合位置B(即卡槽4-6内)向下运动，受到斜向的第二引导面4-4以及侧面的弹出引导面4-5的作用，勾取部6-1能够顺滑地向图4所示的右下方移动到第二引导面4-4的末端4-4-1，离开卡合位置B(即卡槽4-6)。
进一步地，由于卡勾6仍具有一定的回弹力，以及复位引导面4-2相对于第二引导面4-4也具有一定倾斜角度，所以勾取部6-1能够顺畅地滑动到复位引导面4-2上，此时解除按压动作，勾取部6-1会沿着复位引导面4-2向上移动，完成复位过程，回到原始/复位状态位置A，此时笔尾帽2向上移动，恢复到原始/复位状态，即完成弹出过程。
本发明实施例提供的一种笔体弹出结构，结构简单，制作成本低，使用方便，通过按压笔尾帽就可以实现压缩和弹出过程。在实际应用中，手机、平板电脑等电子设备所配备的触控笔均可以采用该笔体弹出结构。另一方面，本结构不仅可以应用在电子设备的触控笔上，还可以用在需要将普通的书写用笔进行收纳的实施方式中。
根据本发明的另一方面，进一步提供了一种触控笔，该触控笔中包括了上述笔体弹出结构。其中，笔体弹出结构的笔杆可以由触控笔的笔杆构成，所述笔尾帽设置在触控笔的顶部。该笔尾帽通过收纳在触控笔内部的 滑槽机构、弹性件等机构，能够在触控笔的顶部进行伸缩活动。
根据本发明的另一方面，还提供了一种电子设备，该电子设备可以是智能手机、平板电脑等，本发明不对此进行限制。电子设备配备有上述触控笔。相应地，电子设备的主体上可以设置有用于容纳触控笔的柱形孔，触控笔可以***其中。在将触控笔收纳于电子设备中时，用户可以通过按压笔尾帽使其缩入笔杆中(对应于上述压缩阶段)，此时笔尾帽的外表面与电子产品的表面齐平，实现触控笔的收纳操作。在需要使用触控笔时，用户可以再次按压笔尾帽，笔尾帽能够从笔杆中弹出，恢复到原始位置(对应于上述弹出阶段)，从而凸出于电子产品的表面，便于用户用手拔出触控笔。
需要说明的是，本发明实施例中提到的方向用语，例如“顶”、“底”、“上”、“下”、“前”、“后”、“左”、“右”等，仅是参考附图的方向，并非用来限制本发明的保护范围。实际上，本发明中提到的“顶”、“底”可以被替换为“第一方向”、与“第一方向”相对的“第二方向”，“顶端”、“底端”可以被替换为“第一端”、与“第一端”相对的“第二端”，“顶部”、“底部”可以被替换为“第一端部”、与“第一端部”相对的“第二端部”。与此类似，本发明中的“上”、“下”，“前”、“后”，“左”、“右”也同样可以做上述替换。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括要素的过程、方法、物品或者设备中还存在另外的相同要素。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保 护范围之内。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
