Description
Technical field
The utility model relates to a kind of toy car, specifically the dynamo-electric road of a kind of toy car one-key switch.
Background technology
Usually, when we require that in toy car an operation push-button realizes two kinds of functions, mostly to come by single-chip microcomputer, when there is no single-chip microcomputer, just have to use two buttons respectively, or adopting the modes such as double-pole switching, these process means all greatly add the volume of toy car or toy car telepilot.
Utility model content
The purpose of this utility model is the dynamo-electric road of toy car one-key switch providing a kind of volume little, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
The dynamo-electric road of a kind of toy car one-key switch, comprise chip U1, resistance R1, key switch SB, electric capacity C1 and triode VT1, described key switch S1 one end connects power supply VCC and triode VT1 emitter respectively, key switch S1 other end distribution contact resistance R1, earth resistance R2, resistance R3 and chip U1 pin 5, the resistance R1 other end connects ground capacity C1 and chip U1 pin 3 respectively, the described resistance R3 other end connects ground capacity C2 and chip U1 pin 4 respectively, chip U1 pin 2 is by resistance R4 connecting triode VT1 base stage, triode VT1 collector electrode connects ground capacity C3 and ground connection load RL, chip U1 pin 6 ground connection.
As further program of the utility model: described chip U1 model is CD4013.
As further program of the utility model: described load RL is toy car loading section.
As the utility model further scheme: described power supply VCC voltage is 9V.
Compared with prior art, the beneficial effects of the utility model are: the dynamo-electric road of the utility model toy car one-key switch adopts chip CD4013 as control chip, and circuit structure is simple, and cost is low, and volume is little, is applicable to very much promoting the use of.
Accompanying drawing explanation
Fig. 1 is the circuit diagram on the dynamo-electric road of toy car one-key switch.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, the dynamo-electric road of a kind of toy car one-key switch, comprise chip U1, resistance R1, key switch SB, electric capacity C1 and triode VT1, key switch S1 one end connects power supply VCC and triode VT1 emitter respectively, key switch S1 other end distribution contact resistance R1, earth resistance R2, resistance R3 and chip U1 pin 5, the resistance R1 other end connects ground capacity C1 and chip U1 pin 3 respectively, the resistance R3 other end connects ground capacity C2 and chip U1 pin 4 respectively, chip U1 pin 2 is by resistance R4 connecting triode VT1 base stage, triode VT1 collector electrode connects ground capacity C3 and ground connection load RL, chip U1 pin 6 ground connection.
Chip U1 model is CD4013.
Load RL is toy car loading section.
Power supply VCC voltage is 9V.
Operation principle of the present utility model is: refer to Fig. 1, when push button switch S B time, R1, C1 and R3, C2 forms two integrating circuit, when CLK (3 pin of CD4013), when the current potential that R (4 pin of CD4013) holds rises to 1/2 ∞, CD4013 output changes, and the time that CLK end arrives is the t1 after SB presses, the time that R end arrives is the t2 after SB presses, t1=R1*C1*In2, t2=R3*C2*In2, that is: when to press time t be t1<t<t2 to SB, CD4013 is after CLK and D end receives the signal that SB sends here, its 2 pin is made to be that low level makes VT1 conducting, load RL obtains electric, when to press time t be t2<t to SB, VT1 turns off, load RL dead electricity.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
