本发明涉及触摸屏输入设备产品领域，特别是涉及一种触摸屏输入设备充电座。

触摸屏输入设备是一种应用于触摸屏上的电子输入设备，例如，智能笔，是一种集光学、电子学和机械学于一体的智能书写笔，在使用过程中，内置于智能笔的红外感应器实时监控用户的书写姿势和视觉角度。当用户的书写姿势和视觉角度不正确时，该智能笔的笔芯会自动回缩进笔头套孔内，直到用户的书写姿势和视觉角度调整为正确姿势时笔芯才重新伸出，供用户正常使用。
现有的触摸屏输入设备通常是通过在触摸屏输入设备上设计金属触点、弹片或者其他形式的导体与电源接触进行充电，常用的设计是：采用电源正负电极与负载设备的正负电极一一对应接触的方式进行充电，即充电座的正负电极与触摸屏输入设备的正负电极一一对应接触充电。
但是，现有的触摸屏输入设备充电座限定了触摸屏输入设备的放置方向，例如，若将触摸屏输入设备置放入充电座时方向放反就会导致充电失败，使用很不方便。

所述第一电极或第二电极和第三电极或第四电极分别对应于触摸屏输入设备上相同极性的电极位置处。
上述触摸屏输入设备充电座，通过底座上设置的两组正负电极且分别设于底座两端外侧的第一电极和第二电极的极性相同，设于第一电极和第二电极之间的第三电极、第四电极的极性相同，所述第一电极或第二电极和第三电极或第四电极分别对应于触摸屏输入设备上相同极性的电极位置处。通过上述技术方案，实现了对触摸屏输入设备的双向充电，即，不用考虑触摸屏输入设备置于充电座的放置方向，均可利用本发明的触摸屏输入设备充电座对触摸屏输入设备进行充电，使用方便；而且，本发明的触摸屏输入设备充电座适用于任何电源系统，对充电电压无要求，也无需额外增加电路，成本较低。
