Abstract

The invention relates to a paintbrush in a computer digital board, in particular to a digital board paintbrush with a suspended refill. The digital board paintbrush with the suspended refill comprises a shell and a refill; a first magnetic body is fixedly arranged on the middle rear section of the refill along a circumferential direction; a second magnetic body is fixedly arranged on the inner surface of the front end of the shell along the circumferential direction; and the polarity of a magnetic pole on the outer wall of the first magnetic body is the same as that of the magnetic pole on the inner wall of the second magnetic body, and the polarities are opposite along the radial direction of the shell, so that the refill is suspended in the shell and positioned on the axis of the shell. When the paintbrush is used for drawing on an operation panel of the digital board, the extrusion and friction between the refill and the shell is decreased in the contraction process of the refill; and the sensitivity of the pressure sensitivity function of the paintbrush is guaranteed.

Description

The floated numerical digit plate of pen core paintbrush

Technical field

The present invention relates to be used for the paintbrush of the numerical digit plate of computer graphics.

Background technology

The numerical digit plate system of computing machine utilizes computer drawing software to carry out the input equipment of mapping operation, and it comprises numerical digit plate and paintbrush, and the operator is by the drafting of paintbrush at the enterprising line bar of the guidance panel of numerical digit plate, thus the mapping operation of realization computing machine.

In order to realize the style of writing pressure sensitive function of numerical digit plate, gathering pressure signal by the paintbrush pen core is wherein a kind of mode, the paintbrush structure of this mode generally comprises a shell and pen core, the front end of pen core is positioned at outside the shell front end, the posterior segment of pen core is positioned at a shell front end, exists certain clearance between a pen core and the shell front end port.According to common custom, people hold paintbrush and paint on numerical digit plate guidance panel when operating, between the axis of paintbrush and the numerical digit plate guidance panel normal with an angle, this just make pen core in telescopic process and between the shell mutual extrusion produce friction, even some paintbrush pen core is gathered pressure information by the pressure transducer that does not produce displacement, also still because resolution of force causes the stressed existence of sensor stress point to hinder.Though the surface of contact between a pen core and the shell can be done very smoothly, extrusion friction is difficult to avoid all the time.Particularly when angle is big, will influence freely stretching of pen core to a certain extent, make sensor stressed not smooth, this will directly have influence on the sensitivity of paintbrush pressure sensitivity function.

Summary of the invention

The purpose of this invention is to provide the floated numerical digit plate of a kind of pen core paintbrush, on numerical digit plate guidance panel, paint when operation, can reduce pen core in telescopic process and the extrusion friction between the shell when paintbrush.

The floated numerical digit plate of pen core of the present invention paintbrush, comprise a shell and pen core, the posterior segment of pen core is positioned at a shell front end, the pen core posterior segment is along circumferentially being mounted with first magnet, shell front end inside surface is along circumferentially being mounted with second magnet, the outer wall of first magnet is identical and radially relative along a shell with the inwall pole polarity of second magnet, and pen core is suspended on the axis that is positioned at a shell in the shell.

First magnet and second magnet tubular body that at least two magnet amalgamations form of all serving as reasons.

Because the outer wall of first magnet is identical with the inwall polarity of second magnet and radially relative along a shell, according to the characteristic that two magnets repel mutually with magnetic pole, pen core is positioned on the columella line, pen core is suspended in the shell and between the shell keeps contactless state.

Reason owing to production technology and physics law, a tubular body magnetic material axially on magnetize and be easy to, and radial magnetizing is very difficult, so first magnet and second magnet are formed tubular body by the back amalgamation of magnetizing of at least two magnets respectively, can make the inside and outside wall of first magnet and second magnet become the two poles of the earth of magnet.

The floated numerical digit plate of pen core of the present invention paintbrush, pen core can be suspended in the shell and between the shell and keep contactless state, when the enterprising line bar of numerical digit plate guidance panel is drawn operation, because the effect that like pole repels mutually, can reduce pen core largely in telescopic process and the extrusion friction between the shell, thereby make pen core flexible more smooth and easy in a shell, also make the stressed smooth and easy of sensor, guaranteed the sensitivity of paintbrush pressure sensitivity function.

Description of drawings

Now in conjunction with the accompanying drawings the present invention is described in further detail.

Fig. 1 is the diagrammatic cross-section of the fore-end of the floated numerical digit plate of pen core of the present invention paintbrush.
