Abstract

The invention relates to a new structure of an electromagnetic pen. The electromagnetic pen is a pen-like tool for writing and operating on the electromagnetic whiteboard. In order to overcome the shortcomings of the existing electromagnetic pen structure, which are relatively complicated, inconvenient to assemble and maintain, and use batteries, the technical solution adopted in the present invention is: the pen tube adopts a "two-in-one" structure, which is composed of a pen holder and an upper cover, and the pen holder is Open, install PCB board, buttons, magnetic ring and coil, pen tip, battery or energy storage capacitor on the pen holder, put the upper cover on the back cover, and fix the two ends with pen cap and connecting sleeve thread respectively, which is convenient for operation and maintenance. The other end of the connecting sleeve is equipped with an electromagnetic eraser or a laser head. Since the capacitor can be used as a power source, the metal sheet is installed on the pen holder of the electromagnetic pen, which can conveniently charge the capacitor, and overcomes the disadvantages of uneconomical, unenvironmental protection and inconvenience of the existing batteries for the electromagnetic pen. The optional function of electromagnetic eraser or laser head is added, and the operation methods are more abundant. There are many combinations to choose from.

Description

technical field [0001] The patent of the present invention relates to a new structure of an electromagnetic pen, which is a pen-like tool for writing and operating on an electromagnetic whiteboard. Background technique [0002] At present, a large part of the electronic whiteboards on the market are made by the principle of electromagnetic induction, which are called electromagnetic whiteboards. The electromagnetic pen sends out an electromagnetic signal when writing or operating on the whiteboard. The whiteboard senses the electromagnetic signal, and determines the position coordinates of the electromagnetic pen according to the strength of the sensed electromagnetic signal and transmits it to the connected computer. The coordinate information and the computer's The image screens are integrated and projected onto the whiteboard through a projector to form a complete interactive presentation system. Users can not only write on the whiteboard with an electromagnetic pen, but...
