Abstract
The utility model provides an induction type touch keystroke, comprising a keystroke unit, a first resistance, a processing unit, a second resistance and a switch, wherein the keystroke unit at least comprises a conductor layer and an insulating layer, and the first resistance is electronically connected with the conductor layer; the processing unit is electronically connected with the first resistance, and the second resistance is electronically connected with the processing unit; and the switch is electronically connected with the first resistance, the second resistance and the processing unit. In this way, when the human hand touches the insulation layer, the processing unit is used to detect the change in the surface charge, and a starting signal is output by the processing unit to drive the switch when the surface charge changes, thereby achieving the effect of safety when in use.
Description
Technical field
The utility model relates to a kind of induction type touch key-press, relates in particular to a kind of variation startup diverter switch of utilizing surface charge, and reaches the induction type touch key-press that has the effect of fail safe when using.
Background technology
General existing button 8 (as shown in Figure 3), two contacts 82,83 that it includes a press section 81 and is located at 81 belows, described press section respectively; Like this, can impose an external force of being scheduled in use on press section 81, described press section 81 be contacted with two contacts 82,83 of its below, and reach the effect that conducting starts.
Though above-mentioned existing button 8 can utilize pushing of external force to reach the effect that conducting starts; But because described press section 81 is the design of mechanism's formula; therefore; regular meeting produces the situation of loose contact or damage because of described press section 81 long-term pressurizeds after using a period of time; cause to have the phenomenon generation of getting an electric shock and influencing other equipment operations when using, cause the fail safe of described button 8 on using relatively poor.
Summary of the invention
Therefore, main purpose of the present utility model is to provide a kind of induction type touch key-press, in the time of can touching insulating barrier at the hand of human body, utilize processing unit to detect the variation of its surface charge, when changing, then export an enabling signal and drive diverter switch, have the effect of fail safe when using and reach by processing unit.
In order to achieve the above object, the utility model provides a kind of induction type touch key-press, includes a push-button unit that has conductor layer and insulating barrier at least; One first resistance that is electrically connected with conductor layer; One processing unit that is electrically connected with first resistance; One second resistance that is electrically connected with processing unit; An and diverter switch that is electrically connected with second resistance and processing unit.
Compared with prior art, induction type touch key-press described in the utility model, in the time of can touching insulating barrier at the hand of human body, utilize processing unit to detect the variation of its surface charge, when changing, then export an enabling signal and drive diverter switch, have the effect of fail safe when using and reach by processing unit.

Embodiment
See also shown in Figure 1, basic framework schematic diagram of the present utility model.As shown in the figure: the utility model provides a kind of induction type touch key-press, and it switches switch 5 by a push-button unit 1, one first resistance 2, a processing unit 3, one second resistance 4 and one and is constituted.
Described push-button unit 1 has a conductor layer 11 at least, reaches an insulating barrier 12 that is laminated on the described conductor layer 11.
Described first resistance 2 is electrically connected with the conductor layer 11 of above-mentioned push-button unit 1, and described first resistance 2 can be an impedance matching resistance.
Described processing unit 3 is electrically connected with above-mentioned first resistance 2, and described processing unit 3 can be a charge detection and Signal Processing Element.
Described second resistance 4 is electrically connected with described processing unit 3, and described second resistance 4 can be a current-limiting resistance.
Described diverter switch 5 is electrically connected with described second resistance 4 and processing unit 3, and described diverter switch 5 can be a relay.Like this, constitute a brand-new induction type touch key-press by above-mentioned structure.
See also shown in Figure 2, user mode schematic diagram of the present utility model.As shown in the figure:, can be connected with required power subsystem 6 by described processing unit 3 and diverter switch 5, and required electronic equipment 7 can be connected with diverter switch 5 when when utilization; And when using if during the insulating barrier 12 of user's hand touch key-press unit 1, the electric charge on described insulating barrier 12 surfaces then can change (just equivalent capacity changes), at this moment, detection and analysis that described processing unit 3 promptly is correlated with, and the electric charge that detects and analyze described insulating barrier 12 surfaces when described processing unit 3 is when changing, then cooperate second resistance 4 outputs, one enabling signal to drive diverter switch 5 by processing unit 3, and allow diverter switch 5 open, to allow 7 starts of required electronic equipment, and because described push-button unit 1 insulate the hand of human body and conductor layer 11 with insulating barrier 12 fully, take place with the situation of avoiding getting an electric shock, so, can reach preferable fail safe in use.
In sum, the utility model induction type touch key-press, in the time of can touching insulating barrier at the hand of human body, utilize processing unit to detect the variation of its surface charge, when changing, then export an enabling signal and drive diverter switch, have the effect of fail safe and reach when using, and then make generation of the present utility model can more progressive, more practical, more meet the required of user by processing unit, really meet the important document of utility application, proposed patent application in accordance with the law.
But the above only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this; Therefore, all simple equivalent of being done according to the utility model claim and utility model description change and modify, and all should still belong in the scope that the utility model patent contains.
