Description

Capacitance pen

Technical field

The utility model relates to computing machine external input device technical field, and specifically, it is a kind of capacitance pen that is applied to touch capacitance plate.

Background technology

Along with the development of science and technology, as a kind of new input equipment, touch capacitive screens is widely used on various mobile devices such as mobile phone, panel computer etc., is a kind of simple, convenient, natural man-machine interaction mode.

People adopt capacitance pen to complete better the man-machine conversation operation with touch electric capacity screen.Traditional capacitance pen generally comprises the electric capacity nib of a body and a body front end etc., by a touch capacitive screens inductance capacitance nib, both form coupling capacitance, and then determine the position of electric capacity nib by the change of Detection capacitance, with the input information of being correlated with.Because sending a faint electric current, capacitance pen is given to touch capacitance plate, on touch capacitance plate and then reflect the content of input information, but the lines of those information such as font or letter are all comparatively stiff, not attractive in appearance, also be not easy to make controller acceptance that it is stored, can not satisfy people's requirement more and more higher to the function of capacitance pen.

Therefore, prior art awaits improving and improving.

Summary of the invention

For the weak point that prior art exists, the purpose of this utility model is to provide that a kind of that the person's handwriting line weight that is presented at touch capacitance plate is changed is abundant, can produce the capacitance pen of the vigour of style in writing of nature.

For achieving the above object, the utility model is realized by following technological means: capacitance pen, comprise penholder, and the cap for brush with penholder one end is spirally connected with the upper cover that the penholder other end is spirally connected, is installed on pen core, pcb board and electric capacity in the penholder cavity;

One end cover of described pen core has a cone shape nib, and the middle part cover of this pen core has a spring, and the two ends of spring are respectively by the protruding stop bit that is arranged on penholder and cap for brush cavity inner wall; The other end of described pen core connects the induction pad by the first silicagel pad, and this induction pad moves with an end of pcb board on being fixed in the pcb board support and contacts, and one end connection one electric conductor; The other end of described pcb board is connected with electric capacity by the second silicagel pad; Described electric conductor is provided with at least two projections, and those projections contact with the button on being embedded in penholder is moving.

Compared with prior art, the beneficial effects of the utility model are: owing to having adopted above-mentioned structural design, the variation of the dynamics when the utility model can the perception personnel that write be write on touch capacitance plate, and then the faint variation by the pcb board sensory current, make the writing line weight of touch capacitance plate change, thereby make it present rich and varied and the effect vigour of style in writing.

The utility model is novel, designs ingeniously, has that the person's handwriting line weight that shows touch capacitance plate is changed is abundant, can produce the characteristics such as effect of the vigour of style in writing.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model capacitance pen.

In figure, each label is respectively: (1) penholder, (2) cap for brush, (3) upper cover, (4) pen core, (5) pcb board, (6) electric capacity, (7) nib, (8) spring, (9) projection, (10) first silicagel pad, (11) induction pad, (12) pcb board support, (13) electric conductor, (14) second silicagel pad, (15) projection, (16) button.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Referring to Fig. 1, the utility model capacitance pen comprises penholder 1, and the cap for brush 2 with penholder 1 one ends are spirally connected with the upper cover 3 that penholder 1 other end is spirally connected, is installed on pen core 4, pcb board 5 and electric capacity 6 in penholder 1 cavity; One end cover of described pen core 4 has a cone shape nib 7, and the middle part cover of this pen core 4 has a spring 8, and the two ends of spring 8 are respectively by projection 9 stop bits that are arranged on penholder 1 and the cap for brush 2 cavity inner walls; The other end of described pen core 4 connects induction pads 11 by the first silicagel pad 10, and this induction pad 11 moves with an end of pcb board 5 on being fixed in pcb board support 12 and contacts, and one end connection one electric conductor 13; The other end of described pcb board is connected with electric capacity 6 by the second silicagel pad 14; Described electric conductor 13 is provided with at least two projections 15, and those projections 15 are moved with button 16 on being embedded in penholder 1 and contacted.

Cone shape nib 7 of the present utility model adopts flexible conducting material to make, and can carry out well current delivery, and can not scratch screen.

In the utility model when work,, when near to or in contact with behind touch capacitance plate surface, nib 7 forms coupling capacitance with the surface of touch capacitance plate, and the position of nib 7 is determined in the change of Detection capacitance, realizes the handwriting input of touch capacitance plate; When extruding nib 7, pen core 4 moves along penholder 1 axial line, and then makes induction pad 11 and pcb board 5 contacts that are connected electric capacity 6; Come the slight change of inductance capacitance by PCB5, on touch capacitance plate, the person's handwriting line weight changes thereby make, and makes it present the vigour of style in writing effect of nature;

Make button trigger a certain function that sets in advance on pcb board 5 by pressing button 16, and then enrich use function of the present utility model.

In sum, the utility model has solved the existing weak point of traditional capacitance pen by above-mentioned structural design, makes the person's handwriting line weight that is presented at touch capacitance plate change abundant, can produce the vigour of style in writing of nature, has marketable value widely.

The above, only better enforcement of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize above-mentioned technology contents to be changed or be modified to the equivalent embodiment of equivalent variations, at this, all the technical solution of the utility model contents that do not break away from, just foundation technical spirit of the present utility model to any simple modification, equivalent variations and modification that above embodiment does, all still belongs in the scope of technical solutions of the utility model.
