附图说明
下面结合附图对本实用新型的具体实施方式做进一步的说明。
图1为本实用新型提供的一种智能笔的结构示意图。
具体实施方式
下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有创造性劳动前提下所获得的所有其他实施例，都属于本发明所保护的范围。
如图1所示为本实用新型提供的一种智能笔的结构示意图，该智能笔包括：笔壳体1、笔芯2和笔帽4，笔壳体1内设置有支架，支架上设置有主处理器、以及与主处理器相连的笔迹收集器和存储器，此外，支架上还安装有可拆卸的笔芯2。具体的，笔迹采集器包括压力感应器和光传感器，光传感器用于采集笔芯2在书写面上行走的运动轨迹，并将采集的运动轨迹数据传输给主处理器，压力传感器用于采集笔芯2在书写面上书写产生的压力传感信号，将采集到的压力传感信号传输到主处理器，主处理器将运动轨迹数据和压力传感信号进行处理，处理成外部设备可读的书写轨迹数据。优选的，笔壳体1内还设置有与主处理器相连的第一数据接口3，笔帽4的一端开口用于容纳笔壳体1的头端，另一端内设置有与外部设备进行无线通讯的无线通讯模块6和第二数据接口5。将笔帽4套接到笔壳体1使第一数据接口3与第二数据接口5进行电性连接时，主处理器通过无线通讯模块6将笔芯2的书写轨迹数据传输到外部设备；当笔帽4与笔壳体1处于分离状态时，主处理器将 书写轨迹数据存储到存储器。具体的，无线通讯模块6为蓝牙无线通信模块、wifi无线通信模块或者Zigbee无线通信模块。以蓝牙无线通信模块为例，当第一数据接口3与第二数据接口5处于连接状态时，主处理器激活笔帽4内的蓝牙无线通信模块，外部设备通过搜索蓝牙信号与该智能笔建立配对连接，主处理器检测到智能笔与外部设备蓝牙连接成功后，将书写轨迹数据实时传输到外部设备。优选的，主处理器在检测到智能笔与外部设备蓝牙连接成功后，还用于判断是否存在未同步的书写轨迹数据，如果是，发出同步请求，待外部设备同意之后，将存储器中尚未同步的书写轨迹数据传输至与之连接的外部设备。
笔芯2的笔头从笔壳体1内伸出，其作用是用来书写，也就是产生笔画和笔顺，可以写在纸上，可以写在白板上。笔芯可以是油性(圆珠)笔芯、水性(中性)笔芯、铅笔芯、可擦写(油墨分解)笔芯、可擦写(油墨固化)笔芯、塑胶(PP、PET、PVC等)笔芯等。
压力传感器，与笔芯2的尾端相连接，当笔芯2书写时产生的压力传递到压力传感器，产生压力传感信号，从而启动主处理器、光传感器等。光传感器与压力传感器相连接，当压力传感器感受到笔芯2书写的压力时，光传感器开始工作，采集笔芯2的运动轨迹数据发送至主处理器。主处理器将运动轨迹数据和压力传感信号进行处理，处理成外部设备可读的书写轨迹数据。
需要说明的是，虽然图1实施例中智能笔是通过光传感器和压力传感器来获取智能笔在书写面上的书写轨迹数据，但本实用新型对智能笔获取书写轨迹数据的方式并不做任何限定。
如图1所示，第一数据接口3设置在笔壳体的尾部，第二数据接口5设置在笔帽4的顶端一侧的凹槽内，优选的，凹槽外设置有防尘塞7。需要将笔迹信息进行实时传输时，将笔帽4的尾部与笔壳体1的尾部进行套接，使第一数据接口3与第二数据接口5进行电性连接；不需要将笔迹信息进行实时传输时，则断开第一数据接口3与第二数据接口5的电性连接。需要说明的是，第一数据接口3和第二数据接口5也可以根据需要分别设置在笔壳体1的侧面，或者设置在笔帽4的侧面，本实用 新型不做限制。
第一数据接口3和第二数据接口5为有线数据接口，采用一公一母对应设置，优选的，第一数据接口3为母头，第二数据接口5为公头。第一数据接口3和第二数据接口5包括USB接口、苹果的Lightning接口、并口和串口，其中，USB接口包括TypeA USB口、TypeB USB口、TypeC USB口、MiniUSB口和MicroUSB口。此外，第一数据接口3和第二数据接口5还集成为电源接口，笔壳体1内设置有电源，所述电源为电池，例如充电电池，与第一数据接口3相连接，第一数据接口3集成电源接口为电源充电，电源通过第一数据接口3与第二数据接口5相连接，为无线通讯模块6供电。
笔壳体1内还设置有开关电路，该开关电路与电源相连接，用于控制电源为主处理器、压力传感器、光传感器供电。
笔壳体1内还设置有指示灯控制电路，该指示灯控制电路至少包括一红蓝绿三色发光二极管和该发光二极管的控制电路，所述控制电路与主处理器相连，根据主处理器传输的不同指令改变所述控制电路的电流强度，以使得发光二极管发出对应颜色类型的光。
本实用新型提供的智能笔将无线通讯模块单独设置在笔帽内，将主处理器、光传感器、压力传感器、存储器等其他器件设置在笔壳体内，笔壳体和笔帽之间通过第一数据接口和第二数据接口之间的热插拔可使得智能笔根据不同场合需求在配备无线通讯功能或者不配备无线通讯功能之间灵活切换，很好地解决了现有技术中的问题。本实用新型满足了智能笔的多种需求，而且设计简单。
以上所述为本实用新型的实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
