在相关技术中，现有电子触控笔通常在内部设置应变片感应笔芯的受力程度以在显示屏划出粗细不同的笔迹，然而应变片内部的力传递结构多为平行四边形框架结构，为确保灵敏度及稳定性四边形尺寸不能做的太小，占用内部空间过大，从而造成内部空间浪费，内部空间利用率不高。
请参阅图1至图5，本申请提出一种电子触控笔。
该电子触控笔包括笔壳和受力传递结构，所述笔壳100具有用于与触控屏接触时使所述触控屏产生电信号的笔芯110；所述受力传递结构设于所述笔壳100内，所述受力传递结构包括应变片200和笔芯支架120，所述笔芯支架120与所述笔芯110连接；所述应变片200包括固定段220以及分别与所述固定段220两端连接且弯折延伸出的受力段210和检测段230，所述笔芯支架120贯穿所述受力段210，且与所述受力段210和所述检测段230连接，所述检测段230上设置有应变计231；所述固定段220朝向所述笔芯110的受力方向延伸，所述固定段220焊接于所述笔壳100的内壁上。
具体来说，应变片200是敏感受力件，应变片200受力后会产生相对明显的形变，通过应变片200贴有应变计231，能检测其变形量，从而计算出受力的大小。在笔芯110进行书写时，笔芯110受到触控屏的挤压，通过笔壳100内与笔芯110连接的笔芯支架120将力依次传递至应变片200的受力段210、固定段220、检测段230，而应变片200朝向所述笔芯110的受力方向延伸的固定段220上表面与笔壳100的内壁通过焊接固定，故应变片200的固定段220是固定不动的。由于应变片200具有弹性，通过应变计231检测应变片200在检测段230产生的形变，进而计算出应变计231的形变量，进而使得电子触控笔可以根据应变计231计算得到的变形量调整在触控屏上书写笔迹的粗细。如此设置，在确保受力传递结构稳定性可靠的前提下，改善目前平行四边形框架结构，笔芯支架120贯穿应变片200的受力段210伸入应变片200的开口空间，笔芯支架120部分容置于该开口空间内，提高内部空间利用率高，留出更多空间给其余零件。
请参阅图1和图4，在一实施例中，所述笔芯支架120包括连接管124、第一支架121、第二支架122和第三支架123，所述连接管124与所述笔芯110连接，所述连接管124与所述第一支架121连接，所述第二支架122的两端分别垂直连接所述第一支架121和所述第三支架123；所述受力段210开设有供所述连接管124贯穿的连接孔211，所述连接管124贯穿所述连接孔211；所述第一支架121与所述受力段210连接，所述第三支架123与所述检测段230连接。如此设置，受力传递结构形成具有开口的双层框架结构，保证受力传递结构的稳定性，减少受力传递结构空间占用率。
请参阅图1至图2，在一实施例中，所述第一支架121的底部延伸出第一翻边125，所述第一翻边121与所述受力段210连接；和/或，所述第三支架123的底部延伸出第二翻边126，所述第二翻边126与所述检测段230连接。可以理解的是，所述第一支架121的底部延伸出第一翻边125，所述第一翻边125与所述受力段210连接。或者，所述第三支架123的底部延伸出第二翻边126，所述第二翻边126与所述检测段230连接。或者，所述第一支架121的底部延伸出第一翻边125，所述第一翻边125与所述受力段210连接；以及所述第三支架123的底部延伸出第二翻边126，所述第二翻边126与所述检测段230连接。通过第一翻边125和第二翻边126的设置，可以提高应变片200的受力敏感度，保证应变计231的检测精度。
请参阅图3，在一实施例中，所述受力段210与所述固定段220垂直，所述检测段230与所述固定段220垂直。如此最大化利用笔壳100内部空间，减少应变片200的空间占用。当然，在其他实施例中，所述受力段210与所述固定段220之间的夹角还可以80度、70度等，所述检测段230与所述固定段220之间的夹角还可以80度、70度等。
请参阅图3，在一实施例中，所述受力段210、所述固定段220、所述检测段230均呈片状设置。通过方片状设置尽可能减少应变片200的体积，减少笔壳100内部空间占用。
请参阅图4，在一实施例中，所述笔壳100的内壁包括有呈环状设置的屏蔽钢管130，所述固定段220焊接于所述屏蔽钢管130的内壁上。可以理解的是，屏蔽钢管130可以起到信号屏蔽、隔离作用，降低信号发散以提高电子触控笔内电极与触控屏的信号交互能力。当笔书写的时候，笔芯110受力传递给笔芯110支架，笔芯110支架再将变形从与应变片200焊接接触的部位即受力段210传递给应变片200，而应变片200的固定段220上表面与屏蔽钢管130通过焊接刚性连接，故应变片200的平面部分即固定段220是固定不动的。由于笔芯支架120刚性比应变片200好，相对变形小很多，最终只有应变片200产生了变形，进而应变计231能检测出变形量。
为保证设置于应变片200的应变计231检测到笔芯110受力程度的精确性，应当保证笔芯110支架的刚度，在一实施例中，所述笔芯110支架的材质采用金属材料。当然，在其他实施例中，笔芯110支架还可以采用具有一定刚性的材料。
在一实施例中，所述笔壳100内还设有控制主板，所述控制主板与所述应变计231电连接。如此应变计231通过检测的形变量发送信号至控制主板，控制主板控制笔芯110在触控屏书写的笔迹粗细。
请参阅图1和图5，在一实施例中，所述笔芯110的端部呈倒圆设置。笔芯110用于与显示屏接触的端部若为尖角设置，笔芯110应力集中，很容易划伤显示屏。通过圆角设置，使得电子触摸笔与显示屏之间接触更为平滑，防止划伤显示屏。
请参阅图1至图5，本申请还提出一种电子设备，该电子设备包括显示屏和电子触控笔，其中，所述显示屏用于供所述电子触控笔触控，该电子触控笔包括笔壳和受力传递结构，所述笔壳100具有用于与触控屏接触时使所述触控屏产生电信号的笔芯110；所述受力传递结构设于所述笔壳100内，所述受力传递结构包括应变片200和笔芯支架120，所述笔芯支架120与所述笔芯110连接；所述应变片200包括固定段220以及分别与所述固定段220两端连接且弯折延伸出的受力段210和检测段230，所述笔芯支架120贯穿所述受力段210，且与所述受力段210和所述检测段230连接，所述检测段230上设置有应变计231；所述固定段220朝向所述笔芯110的受力方向延伸，所述固定段220焊接于所述笔壳100的内壁上。由于本电子设备采用了上述所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本申请的实施例，并非因此限制本申请的专利范围，凡是在本申请的申请构思下，利用本申请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申请的专利保护范围内。
