Wireless electronic pen and its handwriting thickness self-adjusting method

Abstract

The invention provides a wireless electronic pen, comprising a pen shell, a pen core, an elastic element and a pressure detection component, wherein, the pen core, the elastic element and the pressure detection device are arranged inside the pen shell; furthermore, the pen core pushes against and connected with the pen shell by the elastic element; the wireless electronic pen also comprises a handwriting thickness self-adjusting device which is connected with the pressure detection device by wireless signals; furthermore, the handwriting thickness self-adjusting device is connected with the display of a computer by signals. The wireless electronic pen of the invention has high pressure detection precision and simple and feasible detection method, can automatically adjust the thickness of the handwriting according to the pressure and has strong reality-feeling.

Description

technical field [0001] The invention relates to the technical field of electronic pens, in particular to a wireless electronic pen and a method for self-adjusting the thickness of handwriting thereof. Background technique [0002] With the development of digital technology and touch screen technology, pen-like input devices are produced, and the disadvantages of this type of pen input devices are: some are wired, and the wired way limits the free movement of the pen; A pen that changes the thickness of the handwriting, that is, there is no realism. Existing electronic pens with pressure sensitivity generally adopt electromagnetic induction, capacitive induction or resistance induction. The disadvantage of this type of pen is that it is not sensitive enough. Although it has pressure sensitivity, the handwriting is not smooth enough. For example, the Chinese invention patent "Digital pen with track tracking and pressure sensing" with publication number CN1437095A provides two...
