[0002] Electronic pen is also called digital pen or handwriting pen, which is an input device used for inputting text, drawing, operating interface, etc. in cooperation with electronic equipment. A camera or optical sensor is installed at the tip of the electronic pen. The position and movement trajectory of the pen are determined by shooting or sensing the patterns, textures and other features on the screen surface. Some special electronic whiteboards with electronic pens use optical principles to accurately capture writing trajectories and strokes, making writing more natural and smooth, and close to the real writing experience. It is very practical for note taking, signing and other operations.
[0003] The infrared light emitting electronic pen for position input needs a power storage unit, which generally uses a rechargeable battery as the power storage unit, or uses a super capacitor as the power storage unit. For rechargeable electronic pens, the charging method affects the convenience of use. Currently, most electronic pens use connectors to connect to the power supply for charging. For example, a USB socket is provided at the end of the pen tube to connect to the charging circuit. When in use, a conventional USB cable is connected for charging. The above-mentioned connector charging method requires both hands to operate and cannot be operated with one hand, which lacks convenience in use. UTILITY MODEL CONTENTS

The two contact pieces are connected to the positive and negative input terminals of the charging circuit of the light emitting pen body, respectively. Two elastic electrodes are provided at the bottom of the charging base. One elastic electrode is at the center position, and the other elastic electrode is at the eccentric position. The two elastic electrodes correspond to the two contact pieces, respectively.
[0007] Further, the center contact piece and the annular contact piece are on the same center.
[0008] Further, the distance between the two elastic electrodes is about the middle line radius of the annular contact sheet.
[0009] Further, the charging base is further provided with a metal sheet, which is an annular iron sheet.
