Abstract

The utility model discloses a pressure sensing pen which comprises a pen tube, a pen point is arranged in the tip end of the pen tube, the pen point is axially installed in the pen tube in a sliding mode, an extrusion cavity is formed in the position, close to the upper portion of the tail end of the pen point, in the pen tube, a boss is axially installed in the extrusion cavity in a sliding mode, and the boss is connected with the pen point. The two sides of the squeezing cavity are further provided with pressure cavities, air bags are arranged in the pressure cavities, the pressure cavities are filled with the air bags, the bosses can squeeze the air bags, pressure sensors are arranged on the wall bodies of the pressure cavities, when the pen is used for moving, the pen point makes contact with the panel, a user can hold the pen tube to press downwards, the pen point is stressed, and the pressure sensors are arranged on the wall bodies of the pressure cavities. When a user uses the pen, the boss and the pressing piece in the extrusion cavity are driven, pressure is applied to the pressure sensor by extruding the air bag, and therefore the numerical control part of the pen can obtain the pen using force of the user, and the forms of normal strokes under different force are simulated for equipment.

Description

TECHNICAL FIELD

[0001] The utility model relates to induction pen technical field, especially a pressure induction pen. BACKGROUND

[0002] At present, most of touch display terminals are equipped with ordinary handwriting pens, and the display terminal is pressed by the handwriting pen to make the sensing material of the display terminal deform to judge the display note. The traditional method is easy to make the sensing material on the display terminal fatigue, and the touch feeling is not sensitive, which leads to low accuracy of note display. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model aims at providing a pressure induction pen to solve the current pain points in the field.

[0004] The above technical purpose of the utility model is realized by the following technical scheme:

[0005] A pressure induction pen, comprising a pen tube, a pen head is arranged in the pen tube tip, the pen head is axially slidingly installed in the pen tube, an extrusion cavity is arranged above the pen head tail end in the pen tube, a boss is axially slidingly installed in the extrusion cavity, the boss is connected with the pen head, pressure cavities are further arranged on both sides of the extrusion cavity, a gas bag is arranged in the pressure cavity, the gas bag fills the space of the pressure cavity, the boss can extrude the gas bag, a pressure sensor is arranged on the wall of the pressure cavity, the pressure sensor is in contact with the gas bag, and the gas bag can apply pressure to the pressure sensor when being extruded.

[0006] Further, a plurality of balls are arranged around the pen head in the pen tube, the balls can fix the position of the pen head and reduce the sliding resistance of the pen head.

[0007] Further, a buffer spring is connected between the pen head.

[0008] Further, a pressing piece is hinged on the wall of the extrusion cavity on both sides of the boss, the boss slidingly drives the pressing piece to swing, and the pressing piece swinging can extrude the gas bag.

[0009] Compared with the prior art, the utility model has the beneficial effects that when the pen is moved, the pen head is in contact with the panel, the user can hold the pen tube and press down, the pen head is stressed, the boss in the extrusion cavity and the pressing piece are driven, the pressure sensor is extruded by the gas bag to apply pressure, and thus the pen numerical control part can know the force of the user using the pen, and the equipment can simulate the shape of normal pen strokes under different forces.
