Abstract

The utility model provides an umbrella-shaped writing pen which can input signals on a capacitance touch screen, which belongs to the electronics input field. The utility model comprises a pen point which is made from conducting materials and of which the external appearance is umbrella shape. Due to the adoption of the above technical scheme, when the umbrella-shaped writing pen is used for writing in the capacitance touch screen, the pen point and the touch screen form a larger effective area of discharging the capacitance. While the pen point is fully close to the capacitance touch screen, the position where the pen is located is detected. Therefore, the pen point during writing moves on the capacitance touch screen, the circuit in the capacitance screen can easily capture the exact position of the pen point, thus realizing the smooth input.

Description

A kind of umbrella-shaped writing pen

Technical field

The utility model belongs to electronic equipment input field, relate in particular to a kind of on capacitance touch screen the umbrella-shaped writing pen of input signal.

Background technology

The principle of work of existing capacitance touch screen is: during near capacitance touch screen, can form an electric capacity when hand or by other conductors between human body and capacitance plate, the size of this electric capacity is inversely proportional to distance, is directly proportional with surface of conductors is long-pending.When the numerical value of electric capacity reaches the setting value of capacitance plate (electric capacity is the important parameter of capacitance plate, can pass through software or hardware adjustment), the high-frequency current of capacitance plate itself will form discharge loop between human body and capacitance plate.Discharge loop simultaneously can and 4 reference points of capacitance plate between varying in size of electric current detect the relative position of point of discharge with respect to reference point.A lot of such reference points are arranged, 3～5 millimeters of mutual distances on the capacitance plate.When detecting spark location, at first be by being which group reference point is determined a general position in discharge, again by calculating an exact position with respect to the distribution of current on the quaternate reference point (terminal in other words discharges).

The most common operation means are still used finger manipulation on the capacitance plate at present.On the market pointer needs nib could detected by capacitance plate after by compressive strain on the touch-screen, but because pushing the back nib can't move, also just can't realize handwriting functions, even the operation of scrawl can not realize also.It is a cylinder of cutting sth. askew that product is abroad arranged, and instructions points out that it can realize the function of brushing away.Infer that from design concept this structure can't realize hand-written, product description does not propose this product yet handwriting functions.

As the handwriting input on the capacitance plate, must satisfy two conditions: the one, nib can move at capacitance plate surface any direction; The 2nd, the circuit of capacitance plate inside can detect written position in real time, exactly in the moving process.And existing pointer all can not satisfy above two conditions preferably.

In order to solve the existing problem that realizes capacitance touch screen input existence with hand or felt pen, Beijing Chinese princes and dukes department provides a kind of capacitor touch screen pen (application number is 200710179287.9), this pen is made by soft conductive material, hand-held have this pen firmly when capacitance touch screen, nib can produce deformation, thereby the surface of contact that adds writing and capacitance touch screen makes capacitance touch screen can accurately capture the coordinate of pen.But this pen is owing to be that flexible material is made, and when hand-held its write, writes strength and alters a great deal, and causes the variation of surface of contact of itself and capacitance touch screen also very big, and it is not high to write sensitivity yet.The capacitor touch screen pen that practical operation the said firm produces can only be realized clicking operation, can not realize the handwriting input operation.

The utility model content

The purpose of this utility model is to provide a kind of umbrella-shaped writing pen, is intended to solve that hand-written operation that existing pointer exists is insensitive maybe can not realize hand-written problem.

The utility model is achieved in that a kind of umbrella-shaped writing pen, comprises a nib, and described nib is made by conductive material, and its profile is umbrella.

Wherein, described nib is made for the metallic conduction material.

Wherein, described nib is made by the hard conductive material.

Wherein, also comprise a penholder, described penholder is made by conductive material, and described nib is connected with penholder.

Wherein, described nib and penholder part of joining and the part of holding penholder are conductive material.

After adopting above technical scheme, when umbrella-shaped writing pen when capacitance touch screen is write, its nib is bigger with significant surface that touch-screen constitutes electric capacity, so capacitance touch screen can accurately capture the position of nib easilier, thereby realizes smooth input.Because the nib on the utility model does not need to produce deformation when writing, therefore form stable discharge path between nib and the touch-screen, realize smooth writing thereby nib can guarantee in real time, detect accurately written position when capacitance plate surface any direction moves.With respect to for finger direct control capacitance plate, this writing pencil can effectively improve the discrimination of Chinese character hand-written and the comfortableness of operation.An effect the most direct is: can write out littler Chinese character and accurately identification on capacitance plate.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

A kind of umbrella-shaped writing pen of the utility model comprises a nib, and described nib is made by conductive material, and its profile is umbrella.After adopting above technical scheme, when umbrella-shaped writing pen when capacitance touch screen is write, its nib is bigger with significant surface of capacitance touch screen, so capacitance touch screen can accurately capture the position of nib, thereby realizes smooth input.Because the nib on the utility model does not need to produce deformation when writing, as long as it is fully approaching, not necessarily to directly contact, therefore the discharge path between nib and the capacitance touch screen is comparatively stable, and convenient nib moves on the capacitance plate surface, can not occur in moving owing to the unstable not high problem of input sensitivity that produces of the surface of contact between nib and the capacitance touch screen.Below the utility model is elaborated.

See also Fig. 1-3, a kind of umbrella-shaped writing pen 1 of the utility model comprises that nib 3 and penholder 2, described written 3 is connected with penholder 2.Nib 3 on the described umbrella-shaped writing pen 1 and penholder 2 are the conductive material of hard and make, they both metal material make, also can on non-conducting material, coat layer of conductive material, make the surface of umbrella-shaped writing pen 1 have electric conductivity; Described written 3 with penholder 2 between also be connected with conductive material, when human finger was held penholder 2, umbrella-shaped writing pen 1 formed a path to guarantee the normal use of umbrella-shaped writing pen 1 with human body.In addition, because penholder 2 makes for the material of hard, so deformation can not take place in it with capacitance touch screen 5 time, thereby keeps stablizing of itself and capacitance touch screen 5 contacts area.

See also Fig. 1-3 described written 3 and be umbrella, its workplace is a umbrella shape face 4, and described umbrella shape face 4 is similar to spherome surface, and such design can make the umbrella shape face 4 and the surface of contact of capacitance touch screen 5 increase.When umbrella-shaped writing pen 1 on capacitance touch screen 5 during input information, the user hands penholder 2, the part of umbrella shape face 4 contacts with capacitance touch screen 5 on the umbrella-shaped writing pen 1, forms a capacity plate antenna between umbrella shape face 4 and the capacitance touch screen 5; Because the radian on umbrella shape face 4 surfaces is bigger, the surface of contact of itself and capacitance touch screen 5 is also bigger, thereby capacitance can reach setting value and form discharge path and detected by capacitance touch screen 5 between umbrella shape face 4 and the capacitance touch screen 5.

Particularly, see also Fig. 3, when umbrella-shaped writing pen 1 touching capacitance touch screen 5, detect at contact point 6 places formation discharge path and by capacitance touch screen 5, mobile umbrella-shaped writing pen 1, itself and capacitance touch screen 5 form a series of continuous contact points 6, and these contact points 6 are all detected by capacitance touch screen 5 easily, thereby realize realizing smoothly the handwriting input of umbrella-shaped writing pen 1, very convenient.

Similarly, when umbrella-shaped writing pen 1 is realized clicking operation, only need can be detected by capacitance touch screen 5, realize the signal input with the arbitrary position on umbrella-shaped writing pen 1 nib fully near the appointed part on the capacitance touch screen 5.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
