本发明所提及的便携电磁笔， 包括笔杆和活动件， 活动件用于容纳笔杆的至少一 部分并且相对于笔杆活动。 实际应用中， 电磁笔与电磁板配套使用， 完成笔迹输入和 检测。 电磁笔的笔杆内部设置有电容和线圈， 响应电磁板产生的信号。 电磁板内部设 置有多个横行和纵行的线圈电路， 线圈电路通电后， 在一定空间范围内形成电磁场。 电磁笔中的电容和线圈组成的感应电路感应电磁板发射的信号并产生谐振信号， 电磁 板接收谐振信号， 根据变化的电流， 检测电磁笔的位置。
为使本发明的技术特征和优点能够更加明显易懂， 以下结合具体实施例和附图对 本发明作进一步说明。
实施例一：
如图 1所示， 电磁笔由笔杆 1和活动件 2两个部分组成。 活动件 2呈抽拉结构， 可以相对于笔杆 1轴向运动， 即活动件 2与笔杆 1同轴装配， 笔杆 1嵌套在活动件 2 之中。 活动件 2套在笔杆 1的后部， 活动件 2与笔杆 1装配端口的内径与笔杆 1外径 为间隙配合， 优选为零间隙配合。
本实施例中， 笔杆 1的末端周向设有第一卡头 101， 第一卡头 101的等效外径大 于笔杆 1的外径， 第一卡头 101高度的 2倍值与笔杆 1外径之和为第一卡头 101的等 效外径。 活动件 2的内径大于第一卡头 101的等效外径。 活动件 2的前端内侧周向设 有第二卡头 201， 第二卡头 201的等效内径大于笔杆 1的外径， 便于活动件 2沿笔杆 1 轴向滑动， 活动件 2内径长度与 2倍的第二卡头 201高度值之差为第二卡头 201的等 效内径。 第二卡头 201的等效内径小于第一卡头 101的等效外径， 以保证活动件 2在 沿笔杆 1轴向运动到最大长度时， 第一卡头 101与第二卡头 201相接触， 进而限制活 动件 2的运动幅度， 防止活动件 2脱落。 活动件 2与笔杆 1之间为间隙配合。 当活动 件 2与笔杆 1拉开为最大长度时， 便于握持， 缩短到最小长度吋， 也便于携带和放置。
活动件 2的外径也可以小于笔杆 1的内径，则这样活动件 2嵌套在笔杆 1的内部， 伸缩的过程相似， 不再赘述。
活动件 2与笔杆 1之间也可以设置成导槽结构， 如图 2所示， 笔杆 1的两侧设置 导槽 102， 活动件 2可以相对于笔杆 1轴向在导槽 102中滑动， 即可以在携带时缩短 体积， 也可以伸长便于握持。
实施例二：
如图 3所示， 本实施例中， 活动件 2通过转动轴 3与笔杆 1转动连接装配， 活动 件 2呈框架结构。 如图 4所示， 活动件 2的侧面沿着轴向开有凹槽 202， 凹槽 202的 宽度大于笔杆 1的外径， 笔杆 1通过转动轴 3可以折叠进入活动件 2的凹槽 202中放 置。 这样， 就可以转动 180度， 将笔杆 1放置在凹槽 202内， 使笔的长度缩短近二分 之一， 而在从凹槽 202中打开笔杆 1时， 整个电磁笔的长度增加， 更加便于握持。
实施例三： 如图 5所示， 本实施例屮， 活动件 2与笔杆 1为活动插拔结构， 活动件 2的内径 大于笔杆 i的外径， 两者为间隙配合。 活动件 2可直接竖直插拔于笔杆 1的两端， 可 以很方便的插入或拔出， 插入时可以保护电磁笔笔尖， 拔出后套在笔杆 1后端可以延 长笔的长度， 使其更方便握持使用。
本发明的电磁笔简单可靠， 方便携带和放置， 活动件和笔杆的多种装配方式， 可 适合应用于多种工作环境。
