Abstract
A key device capable of using one key to execute different instructions comprises a base plate, a circuit unit which is arranged on the base plate and comprises a first switch and a second switch, a pressing unit, a first triggering component and a second triggering component, wherein the pressing unit is downwardly extended so as to form the first triggering component and the second triggering component. The pressing unit comprises a keycap located above the circuit unit and an elastic element arranged between the keycap and the circuit unit. The elastic element constantly generates an elastic restoring force so that the keycap restores to an original position. Through two-stage force application and pressing along a same direction, the triggering component and the second triggering component move along the direction with the pressing unit so as to turn on the first switch and the second switch successively and respectively. Therefore, different key signals are emitted.

This first trigger part 5 be one by these flexible member 42 bottom surfaces to the projection that extends below; And can with this push unit 4 in the direction A move down and press the topmost thin film 23 of this circuit unit 2; Cause this topmost thin film 23 of this circuit unit 2 to deflect distortion, make the upper conductor 211 and the lower conductor 212 contact conductings of this first switch 21 then.This first triggering part 5 also can be designed to other arbitrary structures, is used to press this topmost thin film 23.The first triggering part 5 and this flexible member 42 of this first preferred embodiment is formed in one made, but also can be an independent element of making, and then is connected with this flexible member 42 again.
This second trigger part 6 be one by these keycap 41 bottom surfaces to the projection that extends below; And can with this push unit 4 in the direction A move down and press the topmost thin film 23 of this circuit unit 2; Cause this topmost thin film 23 of this circuit unit 2 to deflect distortion, make the upper conductor 221 and the lower conductor 222 contact conductings of this second switch 22 then.This second triggering part 6 also can be designed to other arbitrary structures, is used to press this topmost thin film 23.The second triggering part 6 and this keycap 41 of this first preferred embodiment is formed in one made, but also can be an independent element of making, and then is connected with this keycap 41 again.
Make the distance of the distance of this first triggering part 5 to this first switch 21 less than this second triggering part 6 to this second switch 22.Therefore, when pushing this keycap of pushing unit 4 41 A moves in the direction, can make this first trigger part 5 and second and trigger part 6 and successively open this first switch 21 and this second switch 22 respectively.
Consult Fig. 2,3; Apply one strength and push this keycap 41, this push unit 4 in the direction A move, cause the 42 compressing distortion of this flexible member; Can make this first triggering part 5 press the topmost thin film 23 of this circuit unit 2 earlier; Cause this topmost thin film 23 to deflect distortion, and the upper conductor 211 that moves this first switch 21 removes to contact the lower conductor 212 of this first switch 21, and then make this circuit unit 2 produce one first keying signal.At this moment, this second triggers the topmost thin film 23 that part 6 does not press this circuit unit 2 as yet, and the upper conductor 221 of this second switch 22 and lower conductor 222 do not contact conducting as yet.
Consult Fig. 3,4; Continue to apply bigger together strength and push this keycap 41; This pushes unit 4, and A is mobile once more in the direction, then makes this second triggering part 6 press the topmost thin film 23 of this circuit unit 2, causes this topmost thin film 23 to deflect distortion; And the upper conductor 221 that moves this second switch 22 removes to contact the lower conductor 222 of this second switch 22, and then makes this circuit unit 2 produce one second keying signal.
The said switch the 21, the 22nd of this first preferred embodiment is electrically connected with said corresponding lower conductor 212,222 respectively and successively opens by said upper conductor 211,221.Said upper conductor 211,221 directly contacts and conducting with said corresponding lower conductor 212,222 respectively, but also can be by indirect contact and conducting.For example: upper conductor 211 and this corresponding lower conductor 212 of this first switch 21 all are arranged on the end face of this lower film 24 at each interval; And this first trigger part 5 the bottom be provided with a conducting strip; Be electrically connected with the upper conductor 211 and the lower conductor 212 of this first switch 21 respectively by this conducting strip, and make upper conductor 211 and lower conductor 212 conducting indirectly (figure does not show) of this first switch 21.
Consult Fig. 5; One the second preferred embodiment place different with this first preferred embodiment that the utility model can borrow singly-bound to carry out the key device of different instruction is: one second triggering part 6 of this second preferred embodiment is that second articulated section 436 by second framework 434 of this scissors support 43 is to extending below; Can move down and press the topmost thin film 23 of this circuit unit 2 with this keycap 41; Cause this topmost thin film 23 to deflect distortion, make the upper conductor 221 and the lower conductor 222 contact conductings of this second switch 22 then.
Second of this second preferred embodiment triggers part 6 also can be arranged at other positions of this scissors support 43, and makes the distance of the distance of this second triggering part 6 to this second switch 22 greater than this first triggering part 5 to this first switch 21.Therefore, when pushing this keycap 41 A moves in the direction, can make said first to trigger part 5, second and trigger part 6 and successively open this first switch 21 and second switch 22 respectively.
Consult Fig. 5,6; Apply one strength and push this keycap 41, this push unit 4 in the direction A move, cause the 42 compressing distortion of this flexible member; Can make this first triggering part 5 press the topmost thin film 23 of this circuit unit 2 earlier; Cause this topmost thin film 23 to deflect distortion, and the upper conductor 211 that moves this first switch 21 removes to contact the lower conductor 212 of this first switch 21, and then make this circuit unit 2 produce one first keying signal.At this moment, this second triggering part 6 does not press the topmost thin film 23 of this circuit unit 2 as yet, and the upper conductor 221 of this second switch 22 and lower conductor 222 contact as yet.
Consult Fig. 6,7; Continue to apply bigger together strength and push this keycap 41; This pushes unit 4, and A is mobile once more in the direction, then makes this second triggering part 6 press the topmost thin film 23 of this circuit unit 2, causes this topmost thin film 23 to deflect distortion; And the upper conductor 221 that moves this second switch 22 removes to contact the lower conductor 222 of this second switch 22, and then makes this circuit unit 2 produce one second keying signal.
In sum; Push this keycap 41 by applying different strength continuously; Make this first trigger part 5 and this second trigger part 6 with this push unit 4 in the direction A move, can successively press the topmost thin film 23 of this circuit unit 2 respectively, and successively operatively make the upper conductor 211 of this first switch 21 contact conducting with this corresponding lower conductor 212 respectively; And make the upper conductor 221 of this second switch 22 contact conducting, and then send the different keys signal with this corresponding lower conductor 222.
The above person; Be merely two preferred embodiments of the utility model; When not limiting the scope that the utility model is implemented with this, promptly all simple equivalent of being done with the utility model claims and specification change and modify, and all still belong to the scope of the utility model patent.
