Description
Technical field
The present invention relates to a kind of capacitance pens, in particular to a kind of passive type capacitance pen.
Background technique
Capacitance pen point active capacitance pen and passive type capacitance pen at present on the market.Active capacitance pen is defeated using power supply
Enter electromagnetic signal simulation touch point and realizes that touch is write, it is with high costs because joined the logistics such as chip, circuit, power supply；Passively
Formula capacitance pen utilizes the electric conductivity of pen body material, realizes that touch-control is write, low in cost, but in the case that pen body is conductive, by
Material limitation is larger, and causes the mistake of touch screen to touch in the case where the setting of a part of capacitance plate identifies a lower height of situation, does not have
The characteristic of imitative interference.
Summary of the invention
In order to overcome the shortcomings of that existing technology, the present invention provide a kind of passive type capacitance pen.
Technical solution of the present invention is as described below:
A kind of passive type capacitance pen, including conductive pen point, non-conductive pen body and the circuit being arranged in inside the non-conductive pen body
Component, which is characterized in that

Specific embodiment
With reference to the accompanying drawing and the present invention is further described in embodiment:
As shown in Figs. 1-2, a kind of passive type capacitance pen, including conductive pen point 1, non-conductive pen body 2 and setting are described non-conductive
Circuit unit inside pen body 2, circuit unit include the first copper sheet 3, energy storage capacitor 4, the second copper sheet 5, spring 6 and circuit board
7, the first copper sheet 3, energy storage capacitor 4, the second copper sheet 5, spring 6 are arranged on circuit board 7, one end of energy storage capacitor 4 and the first bronze medal
Piece 3 connects, and the other end of energy storage capacitor 4 is connect with the second copper sheet 5, and the first copper sheet 3 is connect by spring 6 with conductive pen point 1, the
Two copper sheets 5 are located at the inside of non-conductive 2 hand grip portion 21 of pen body, and the size of the second copper sheet 5 is matched with hand grip portion 21.When with quilt
When capacitance plate is write, manpower comes into contact in a large area dynamic formula capacitance pen with non-conductive 2 hand grip portion 21 of pen body, hand and the second copper sheet 5 it
Between formed an equivalent capacity, due to the second copper sheet have lower potential, the electric current that energy storage capacitor 4 is absorbed from capacitance plate, and
The second copper sheet 5 is flowed to, the potential of the second copper sheet 5 is higher than manpower at this time, and electric current is transferred to manpower from the second copper sheet 5, and passes through
Human body is discharged into the lower surrounding enviroment of potential, completes absorption and release that point electric current is corresponded to capacitance plate.
Preferably, spring 6 is scroll spring.
Preferably, circuit board 7 is provided with the card slot 71 matched with spring 6, and spring 6 is fixed on circuit board by card slot 71
On 7.
Preferably, the first copper sheet 3 is connect by way of scolding tin with spring 6.
The present invention is with following the utility model has the advantages that the present invention in the case where pen body is non-conducting material, is added in inside
One circuit realizes passive conductive, can effectively avoid the mistake touching to touch screen；The configuration of the present invention is simple, production cost is low, touching
It is splendid to control writing experience, greatly improves writing experience and application range.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
Illustrative description has been carried out to the invention patent above in conjunction with attached drawing, it is clear that the realization of the invention patent not by
