Among the above -mentioned technical scheme, when installing rotatory inswept first, two hall element of the carousel of magnet steel, first, two hall element have sensing signal output respectively, merge into signal output of the same kind after the treatment circuit is handled, reach the effect of the double output of signal.
Description
Technical field
The utility model is specifically related to a kind of power steering sensor for electric bicycle circuit arrangement.
Background technology
Current power steering sensor for electric bicycle device mainly contains following three classes:
The first kind is single Hall assistant sensor (1 Hall element);
Equations of The Second Kind is two Hall assistant sensors (2 Hall elements+1 micro controller system);
3rd class is many Halls assistant sensor (3 or more Hall elements+1 micro controller system);
The first kind is simple, cost is low, but has use limitation, the large and output pulse signal quantity < 8 of volume.Second and third class can be accomplished that volume is little and can be exported more multipulse signal quantity > 10, but cost is high, and the micro controller system added also has certain fault rate, causes certain fugitiveness.
Summary of the invention
The purpose of this utility model is just to provide a kind of power steering sensor for electric bicycle circuit arrangement, it is the improvement carried out on original Second Type sensor circuit device, reduce productive costs, improve the stability of system, improve the safety of battery-driven car in power-assisted is ridden.
For achieving the above object, the utility model have employed following technical scheme:
A kind of power steering sensor for electric bicycle circuit arrangement, it is characterized in that: the wiring board comprising rotating disk and the layout corresponding with rotating disk doing divertical motion, on rotating disk, circumferential uniform intervals arranges magnet steel, wiring board is provided with first and second Hall element Q1, Q2, first and second Hall element Q1, Q2 are connected with treatment circuit, and treatment circuit processes the signal that first and second Hall element Q1, Q2 input and exports the signal after process.
In technique scheme, when being provided with inswept first and second Hall element of the turntable rotation of magnet steel, first and second Hall element has sensing signal to export respectively, merges into a road signal and exports, reach the effect of the double output of signal after processing circuit processes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic diagram wiring board being arranged first and second Hall element, treatment circuit;
Fig. 3 is the waveform schematic diagram that the utility model exports.
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 the utility model is taked as shown in Figure 1, 2, a kind of power steering sensor for electric bicycle circuit arrangement, comprise the wiring board 13 of the rotating disk 11 and layout corresponding with rotating disk 11 doing divertical motion, on rotating disk 11, circumferential uniform intervals arranges magnet steel 12, wiring board 13 is provided with first and second Hall element Q1, Q2, first and second Hall element Q1, Q2 are connected with treatment circuit, and treatment circuit processes the signal that first and second Hall element Q1, Q2 input and exports the signal after process.
In technique scheme, first and second Hall element is weldingly fixed on same wiring board 13 simultaneously, time the rotating disk 11 being provided with magnet steel 12 rotates first and second Hall element inswept, first and second Hall element has sensing signal to export respectively, after processing circuit processes, merge into 1 road signal export, reach the effect of the double output of signal.
Concrete scheme is: treatment circuit comprises the first resistance R1, the second resistance R2, electric capacity C3 and light-emitting diode LD1, sequentially be connected in series with the first resistance R1, electric capacity C3, light-emitting diode LD1, the second resistance R2 after first and second Hall element Q1, Q2 parallel connection, the size of the first resistance R1 is 100R, the size of the second resistance R1 is 20R, the model of electric capacity C3 is 104K/X7R, 50V, and the model of light-emitting diode LD1 is L-5T34LRC.Wiring board 13 is arranged 3 core pig-tail wire J1 to export the signal after processing circuit processes, the model of first and second Hall element is EW732, treatment circuit superposes and output filtering first and second Hall element Q1, Q2 output signal, also plays the effect of signal designation simultaneously.
In Fig. 2: Q1 and Q2 is first and second Hall element, D1 and C1 is in parallel, D1 and C1 is the filter circuit of power supply part, and J1 is 3 core pig-tail wires, is that the positive VDD of power supply, power-GND and signal export signal-OUT respectively.
2 impulse singla T1-1 and T1-2 that Q1 exports, 2 impulse singla T2-1 and T2-2 that Q2 exports, Q1 and Q2 signal exports summed signal Q3:T3-1, T3-2, T3-4, T3-4 after merging, and can realize the double output of quantity of impulse singla, as shown in Figure 3.
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.
