Invention content

The invention is intended to provide a kind of silica gel electronic signature pen, so that it writes feel as close as common book WriteMode.

Silica gel electronic signature pen in this programme, includes the writing portion set on penholder lower end, and writing portion is equipped with taper The nib of silica gel material.

For writing part in the lower end of penholder, nib thereon passes through application for describing in the electrical screen of glass material The extensive work of people, discovery can promote writing feel with silica gel material to make nib, and some factors are silica gel and glass Frotteurism between glass is similar to state of the common nib on paper, so the hand write in the electrical screen of glass material The very close common written of sense.

Further, pressure inductor is equipped between writing portion and penholder.Pressure inductor can detect writing portion phase when writing To the pressure that penholder generates, and pressure change can be recorded, the state write for reflecting user, it might even be possible to pass through note The data of record are identified for the identity to writer.

Further, cavity is equipped in nib, cavity is connected to air pressure regulator by conduit.Air pressure regulator passes through Conduit controls the air pressure of written internal cavity, in cavity different air pressures can make nib that different hardness be presented, air pressure is bigger Then nib is harder, can reach different writing feels.Air pressure regulator can be the devices such as cylinder or air compressor.

Further, air pressure regulator is cylinder, piston and cylinder inner wall thread connection, and the piston first line of a couplet is connected to protruding Rotational handle.Piston can be moved by controlling rotational handle, to change the air pressure in nib.And piston passes through spiral shell Line moves in the cylinder, and rotation only moves a screw pitch in one week, can realize the fine tuning of position by controlling its turnning circle. To ensure the sealing performance of threaded connection place, threaded portion can be made using material partially flexible so that the screw thread of engagement Gap is avoided by elastic mutually squeeze, diaphragm seal can also be added on piston to improve the sealing performance of piston circumference.

Further, nib in cavity twist.Spiral cavity can account on the basis of ensureing written intensity According to volume larger inside nib, the advantage of more volume cavity is that larger range of air pressure adjustment may be implemented.Phase therewith Although corresponding completely hollow cavity has the volume of bigger, if the air pressure in cavity is insufficient, nib will also result in Intensity dead-soft is so that be difficult to write.And the central part of spiral shape cavity still has the silica gel entity of part that can play certain support Effect.

Further, the cylinder is electric cylinder, and the controller of electric cylinder is electrically connected with pressure inductor, electric cylinder Controller be used for adjust cylinder make pressure inductor reading tend to preset value.Setting one that should be artificial before use is default Value, then the controller of electric cylinder is adjusted written air pressure according to the feedback of pressure inductor so that reading is as possible Trend preset value, may be implemented automation adjustment pressure to improve feel.It may be arranged as only in the anti-of pressure inductor Feedback just starts automatic regulating function in a closed interval, avoids carrying out meaningless adjustment when signature pen is not used.It is described Closed interval should be possible pressure limit when normally writing.This programme can not also enable complicated control logic, be only used for Air pressure reinforcement is carried out when nib pressure is less than basic value, keeps it in basic value or more.

Specific implementation mode

Below by specific implementation mode, the present invention is described in further detail：

Reference numeral in Figure of description includes：Penholder 1, written seat 2, nib 3, cavity 4, foil gauge 5, conduit 6, gas Cylinder 7, piston 8, rotary head 9, diaphragm seal 10.

Embodiment one is basic as shown in attached drawing 1,2：This silica gel electronic signature pen shape such as common pen, vertical pen Bar 1 is plastic material.It is embedded with written seat 2 in the lower end of penholder 1 and is used as writing portion.The lower face of written seat 2 is bonded with silica gel The nib 3 of material, nib 3 is tapered, is internally provided with spiralling bar shaped cavity 4, this section of cavity 4 in figure can To see, central axes are overlapped with the central axes of penholder 1.For comparing solid nib 3, the nib 3 in this programme is due to this The presence of cavity 4 can be more soft, and the air pressure change in cavity 4 can also influence the pliability of nib 3.

The upper surface of written seat 2 is equipped with foil gauge 5, and foil gauge 5 can be used for detecting the pressure between written seat 2 and penholder 1 Power, this pressure value can change with the state that people write.The data that foil gauge 5 obtains can be by conducting wire to unofficial biography It is defeated.

The cavity 4 is connected to the cylinder 7 on 1 top of penholder by conduit 6, and piston 8, piston 8 and cylinder are equipped in cylinder 7 7 inner wall is coupled by screw thread, is with having to ensure that threaded connection place has enough leakproofness, the screw thread Made of the plastics of certain elasticity, certain elastic tight that is threaded through on 7 wall of piston 8 and cylinder fits together, and reaches Enough leakproofness.And be additionally provided with the diaphragm seal 10 of horizontal piece in the top of piston 8, the edge of diaphragm seal 10 again by Elastic material is tightly attached to 7 inner wall of cylinder, and the setting of diaphragm seal 10 can reinforce the sealing performance of the cylinder 7.When piston 8 occurs to turn When dynamic, then it can be moved up and down under the guiding role of screw thread, to change the air pressure in cylinder 7.

Cylindrical rotary head 9 is welded in the upper surface of piston 8, the interior edge of diaphragm seal 10 is fixedly bonded to rotary head 9 Outer wall, the top of rotary head 9 stretches out 1 upper end of penholder, drives piston 8 to rotate by holding rotary head 9 convenient for people.Piston 8 rotations will produce axial movement, to change the air pressure in cylinder 7, since the cavity 4 of cylinder 7 and nib 3 is by leading What pipe 6 was connected to, the air pressure change of cylinder 7 equally influences whether that the air pressure of written 3 cavitys 4, different air pressures then make nib 3 Hardness changes, and also just makes writing feel that significant change occur.In embodiment two, with embodiment one the difference is that Features described below.

The lower face of cylinder be equipped with external air check valve, ambient atmos only in cylinder air pressure be less than atmospheric pressure when into Enter check valve, the make-up gas into cylinder, this check valve can be turned off manually as needed.
