Specific embodiment
Below by way of specific instantiation, embodiments of the present invention are described, those skilled in the art can be by this specification
Disclosed content understands other advantages and effect of the present invention easily.The present invention can also be by addition different concrete realities
The mode of applying is carried out or applies, and the every details in this specification can also be based on different viewpoints and application, without departing from
Carry out various modifications and changes under the spirit of the present invention.It should be noted that, the embodiment in the case of not conflicting, in the application
And the feature in embodiment can be mutually combined.
As shown in Figures 1 and 2, the present invention provides a kind of trigger-type contact making device 1, for for located at capacitance touch screen 2 table
Face, carries out unartificial triggering with the specified location to capacitance touch screen 2 surface；Wherein, described trigger-type contact making device 1 includes:
Holder 11, fixture 12, conductive contact 13, electrically connect described conductive contact 13 and be also associated with the derailing switch of capacitive device 14
Part 15, electrically connect described switching device 15 and be connected with the drive circuit 17 of external communication interface 16.
Described holder 11, lower surface is provided with the fixture 12 for being fixed to capacitance touch screen 2 surface；In one embodiment,
In the form of sheets, described fixture 12 includes described holder 11: sucker, is mechanically fixed support, stretching elastic ring or viscose etc., by for example
Described trigger-type contact making device 1 is fixed on described capacitance touch screen by the modes such as sucker suction, stretching elastic ring colligation, viscose bonding
2.
Described conductive contact 13, located at described holder 11 lower surface and corresponding to described capacitance touch screen 2；In described triggering
Formula contact making device 1 is fixed to the surface of described capacitance touch screen 2 by fixture 12, makes described conductive contact 13 correspond to electricity
Hold the part needing to realize touch operation on touch-screen 2, such as button etc..
And, as shown in Fig. 2 in one embodiment, described switching device 15, capacitive device 14 and drive circuit 17 set
In the upper surface of described holder 11, preferably, the position of setting is positive and negative with described conductive contact 13, so can subtract
Few length of arrangement wire, reduces the impact to conductive contact 13 capacitance characteristic for the wiring lead.
See also Fig. 3, in order to the operation principle of electric signal interaction between above-mentioned device to be described.
Described switching device 15, connects described conductive contact 13 and is also connected with described capacitive device 14, described derailing switch
The conducting of part 15 makes described capacitive device 14 turn on conductive contact 13 so that described conductive contact 13 carries capacitance characteristic, from
And trigger described capacitance touch screen 2；The shutoff of described switching device 15 makes described capacitive device 14 and conductive contact 13 disconnect
To eliminate the capacitance characteristic of described conductive contact 13 it is preferred that the capacitance that described conductive contact 13 has during capacitance characteristic is use up
The coupling capacitance that amount is produced with trigger-type capacitance touch screen 2 close to finger, such as 3～5 pico farads, so to simulate finger
Touch capacitance touch screen 2.
In one embodiment, described conductive contact 13 includes: conductive sponge, conductive rubber, electric silica gel or conductive fabric；By
Almost nil in the capacitance of this conductive contact 13 itself, even if often keeping therefore between conductive contact 13 and capacitance touch screen 2
Contact condition also will not trigger capacitance touch screen 2, and can make this conductive contact 13 and capacitive character device when switching device 15 turns on
Part 14 conducting is got up, thus moment increases the capacitance of conductive contact 13, then triggers capacitance touch screen 2.
As long as due to when most of capacitive touch screen is touched by object this object carry and its faint coupled capacitor just
Screen can be triggered, and the output capacitance of the pin of most of electronic device or contact is both greater than the coupling capacitance of human finger,
Therefore in the state of conductive contact 13 keeps often contacting with capacitance touch screen 2, use electronics device simulation human finger's capacitance characteristic
It is difficult, once common electronic device is difficult to accomplish the mode directly driving conductive contact 13 to trigger screen because having pin and lead
Electric contact 13 be joined directly together may result in conductive contact 13 capacitance rise towards or more than human finger capacitance from
And false triggering touch-screen, common electronic device must realize conductive contact 13 and capacitive device 14 by being able to ensure that during shutoff
Between the switching device 14 that is electrically isolated completely to indirectly to drive conductive contact 13, described switching device 15 can be with machinery
The device of formula switchblade knife, and or electromagnetic type relay etc.；Described capacitive device 14 includes: electric capacity or metal pad, example
Such as small capacitances (such as 3～5pf about) or a larger metal pad or directly and circuit board power supply or
Ground metal pad be connected can because the capacitance under any of the above mode all be not less than human finger touch touch-screen
Coupling capacitance, but can be closer to.
From the above, described switching device 15 can include electromagnetic type relay or mechanical relay, certainly also can be
Other are able to ensure that the implementation realizing the switch of electrical isolation between conductive contact 13 and capacitive device 14 during shutoff, reason
Think under state, be to realize completely electrical isolation.
Described drive circuit 17, connects described switching device 15 and is connected with external communication interface 16 (for example conventional string
Mouthful, general i/o mouth etc.), turn on described switching device for receiving triggering electric signal from described external communication interface 16 to drive
15.In one embodiment, described drive circuit 17 includes process chip, and described process chip is according to described triggering electric signal come right
Described switching device 15 is turned on；In one embodiment, described drive circuit 17 includes process chip, described process chip
According to prestored instruction, described switching device 15 can be turned on or off.
Specifically, the application mode of the present invention is: the trigger-type contact making device 1 of the present invention is fixed on capacitive touch
Touch on screen, conductive contact 13 is contacted by the region of automatic touch-control with needing on capacitive touch screen or keeps producing triggering
Distance, the function in this region and shape all can be arbitrarily it is only necessary to make described in the contact making device 1 when setting out of the present invention to be used
Conductive contact 13 and described region align, and such as this region shows a button, the drive circuit 17 of apparatus of the present invention
Receive the triggering electric signal of such as curtage form by external communication interface 16, conducting switching device 15 is to incite somebody to action then
Capacitive device 14 and conductive contact 13 mutual conduction are got up, and moment makes the capacitance of conductive contact 13 become greater to close to human body hand
The capacitance referring to, thus the button simulating on the state triggering capacitance touch screen 2 that finger presses down reaches automatic triggering
Purpose；When described triggering electric signal disappears, drive circuit 17 can turn off switching device 15, so that the capacitance of conductive contact 13
Revert to the state close to zero, be equivalent to and simulate the state that finger lifts thus the button that discharges on screen, complete with regard to this
Become entirely automatic touch-control process.
