Description
Technical field
The utility model relates to a kind of battery-driven car operational and controlled key button circuit.
Background technology
Current Electrical Bicycle/Segway Human Transporter display instrument mainly divides two large classes, specific as follows:
Category-A: button and meter body coexist in a housing;
Category-B: meter body part and split button are separated in two independently in housing, connect each other by signal wire (SW).
Wherein: category-A structure is relatively simple, category-B more complicated.Button operation control circuit is mainly in the market: button is often opened or normally closed mechanical switch signal or low and high level actv. tap light current on-off signal, above circuit realiration all needs loaded down with trivial details keypress function lead-in wire, that is: a function button needs a signal wire (SW) corresponding with it, if when having the even more button of three, four buttons, need more key circuit pig-tail wire, easily realize when category-A, can be connected by circuit board wiring.But in category b cases then must by signal wire (SW) connect button with display main body, in this kind of situation, signal wire (SW) number larger impact is all existed on production efficiency, stability and cost.
Current category-B split button draws core number when button quantity is more than or equal to 2 will be more than or equal to 3, and comparision of production is numerous and diverse, and production efficiency is low, and cost is high, and without linear speed-regulating function.If increase linear Hall speed-regulating function (function of similar current electric bicycle speed-regulating handle) on category-B split button basis, about so the connection pig-tail wire quantity of split button and meter body part will increase by 2 cores on the original basis; It is even more that total core number is increased to 5 cores.So just cause split button production and processing technology numerous and diverse, inefficiency, cost is high.In addition, category-B instrument is when Full Vehicle System coupling, speed control crank function is all generally that system additionally increases an electric bicycle speed-regulating handle, and car load is by increase cost and bring system bus to increase (increase handle 3 heart yearn), and man-hour and the material cost of car load assembling all will increase.
Summary of the invention
The purpose of this utility model is just to provide a kind of electric vehicle instrument split key circuit, increases handle speed-regulating function simplified push button pig-tail wire simultaneously, reduces productive costs, enhance productivity and stability.
For achieving the above object, the utility model have employed following technical scheme:
A kind of electric vehicle instrument split key circuit, it is characterized in that: comprise the wiring board that split button is arranged, wiring board is integrated with shift knob, governor Hall element and micro controller system, micro controller system is connected with shift knob, governor Hall element respectively, is sent to meter body after the manipulation signal of micro controller system receiving key button and the output signal of governor Hall element carry out analyzing and processing by 2 heart yearns.
In technique scheme, simplify split button pig-tail wire quantity, simplify assembly process, enhance productivity, save material, reduce productive costs, on same split key circuit, be integrated with handle speed-regulating function simultaneously, manipulate easy, simplify car load assembly process, improve car load efficiency of assembling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is specifically described.Should be appreciated that following word only in order to describe one or more concrete embodiments of the present utility model, considered critical is not carried out to the protection domain that the utility model is specifically asked.
The technical scheme that this practicality is taked as shown in Figure 1, a kind of electric vehicle instrument split key circuit, comprise the wiring board 10 that split button is arranged, wiring board 10 is integrated with shift knob, governor Hall element 12 and micro controller system 11, micro controller system 11 is connected with shift knob, governor Hall element 12 respectively, is sent to meter body 14 after the manipulation signal of micro controller system 11 receiving key button and the output signal of governor Hall element carry out analyzing and processing by 2 heart yearns 13.
In technique scheme, simplify split button pig-tail wire quantity, simplify assembly process, enhance productivity, save material, reduce productive costs, on same split key circuit, be integrated with handle speed-regulating function simultaneously, manipulate easy, simplify car load assembly process, improve car load efficiency of assembling.
Concrete scheme is: the model of micro controller system 11 is STM8S003F3, and the model of governor Hall element 12 is SS49E, and the model of 2 heart yearns 13 is UL26#1007, and the model of shift knob is SW-60LTCM50F1.
Split key part internal circuit part is mainly provided with 3 electronicies package, that is shift knob, linear hall element, micro controller system, integrated installation is on a small-sized skilful wiring board simultaneously for three, and the manipulation signal of shift knob and the output signal of linear hall element all send meter body part to by power supply lines after micro controller system process.The signal wire (SW) number of connection of split button and meter body part is only 2 heart yearns (power supply just, power-).The principle of data transmission is the carrier communication based on split key circuit power lead, and the power supply of 2 heart yearns is positive and negative not only as power supply but also as the transmission path of data communication.SS49E linear Hall responds to the corresponding output linearity analog voltage signal of change of mobile magnet steel field intensity, realizes handle speed-regulating function.
In the utility model, for the traditional B class instrument circuit of Electrical Bicycle/Segway Human Transporter, reduce the connection signal line number of leads of split button and meter body, simplify production technology, reduce productive costs, increase linear Hall speed-regulating function simultaneously, strengthen system availability and do not increase pig-tail wire quantity, simplifying production technology, reduce costs, reducing car load productive costs simultaneously.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; to know in the utility model after contents; under the prerequisite not departing from the utility model principle; can also make some equal conversion to it and substitute, these convert on an equal basis and substitute and also should be considered as belonging to protection domain of the present utility model.
