Embodiment
A kind of electric bicycle universal charging inlet transducer, unlike the prior art
Including small-power rectifier bridge stack module, power module, photoelectric coupler module, LED lamp module, power rectifier bridge heap mould
Block and relay module.
The effect of described small-power rectifier bridge stack module is to provide power supply to power module.
The effect of described power module is to provide power supply to photoelectric coupling module and relay module.
The effect of described photoelectric coupler module is the interface modes obtaining electric bicycle from electric bicycle interface
Control relay module after information, make relay jump to corresponding interface modes.
The effect of described LED lamp module is after the charging inlet accessing car, transducer again with the delivery outlet phase of charger
Docking, LED lamp module obtains the interface modes of charger from the output interface of charger, and controls LED and correctly indicate charging
The interface modes of device.As it is shown in figure 1, electric bicycle interface modes LED indicating circuit is by 3 LED, resistance and audion
Composition.P1 with R1 connects, P2 with R2 connects, P3 with R3 is in parallel with R12 after connecting.Because LED is belonging to the one of diode,
So can only powering with unidirectional current and there is the characteristic of one-way conduction.So only when outN-2 be positive pole outL-2 be negative
During pole, the LED being numbered P1 just turns on shinny, in like manner only when outL-2 be positive pole outN-2 be that negative pole, outL-2 are for just
When pole outT-2 is negative pole, the LED being numbered P2, P3 just turns on shinny, the most then will not be bright.Because outL-2 multiplexing
, and audion serves not only as signal and amplifies, and can also use as switch.So audion effect is in order to really
Protect only outL-2 be positive pole outT-2 be that negative pole is numbered the LED of P1 in this case and just turns on shinny, it is ensured that whole
LED can correctly indicate.
The effect of described power rectifier bridge heap module is that the electric current to charger output carries out rectification.
The effect of described relay module is to be communicated to electric bicycle again by relay module, is finally completed and is transformed into
The process of charging.
As in figure 2 it is shown, electric bicycle respectively with LED lamp module, photoelectric coupler module, small-power rectifier bridge stack module
Connect with relay module；Wherein LED lamp module is connected with charger；Wherein photoelectric coupler module is with relay module even
Connect；Its middle low power rectifier bridge stack module is connected with power module, power module respectively with photoelectric coupler module and relay
Module connects；Wherein relay module is connected with power rectifier bridge heap module, and power rectifier bridge heap module is with charger even
Connect.
Described photoelectric coupler module is obtained, each photoelectrical coupler correspondence detection one by three photoelectrical couplers parallel connections
Plant charger interface pattern.As it is shown on figure 3, photoelectrical coupler is internal by passing through that light emitting diode and phototriode form
Light realizes the device controlled.Photoelectrical coupler is the device with light as transmission medium, because the transmission of light is unlike the signal of telecommunication
Transmission equally needs public ground wire, so the circuit of photoelectrical coupler both sides can not altogether.Therefore photoelectrical coupler is anti-
Interference performance is stronger, and efficiency of transmission is the highest and Comparision stable simultaneously.Three photoelectrical couplers are as this partial circuit
Critical piece is used for three kinds of different Interface status of detection respectively.When outN be positive pole outL be negative pole time, photoelectrical coupler G1
Work and G2 and G3 does not works, when outL be positive pole outN be negative pole time, photoelectrical coupler G2 work and G1 and G3 does not works, when
OutL is positive pole outT when being negative pole, photoelectrical coupler G3 work and G1 and G1 does not works.The effect of resistance is to photoelectric coupling
Device current limliting, prevents the electric current because flowing through its inside excessive and burns.The effect of commutation diode is to prevent photoelectrical coupler by instead
Guarantee that the light emitting diode inside device can normally work to puncturing.The effect of PNP triode is present to ensure that only outL is
Positive pole outT-is that negative pole photoelectrical coupler G3 in this case just works, it is ensured that optocoupler circuit can correctly detect difference
The state of interface, photoelectrical coupler plays very important effect in the isolation in the input and output of circuit.Ensure that outL,
The circuit of these high pressure of outN and outT does not interferes with the normal work of VCC_5V low-voltage circuit part, ensures that whole
Detection module can be properly functioning.
Described power rectifier bridge heap module is made up of three power rectifier full-bridges, and each power rectifier full-bridge is just
Pole is all connected with power supply, and negative pole is all connected with 0 line, after the outfan of each power rectifier full-bridge self connects, and correspondence respectively
For L, T, N-port；Two rectifier bridge stack cooperation change the voltage of a kind of Interface status, it is achieved input end interface is different
Dipole inversion is unified for fixing positive and negative polarity.
Described relay module uses maximum service rating to be 300W, and running voltage is 5V, 12V, 24V, 36V or 48V
Relay.
Relay is commonly used in electronic control circuit as a kind of switching device, and having can be with the big electricity of Small current control
Stream, low-voltage control high voltage, efficiently and the advantage such as safety.As the important module of the present invention, relay is electronic certainly at each
Mutually change and the work of turning circuit play the effect of key between driving interface modes.Two relay co-controllings one
Redirecting of the pattern of kind, uses altogether redirecting of 6 Control Three models.As shown in Figure 4, when the interface of electric bicycle
" L " is negative pole " N " when being positive pole, and relay K 1 and K2 works, and K1 turns on cathode voltage, and K2 turns on negative pole；Work as electric bicycle
Interface " L " be positive pole " N " when being negative pole, relay K 3 and K4 works, and K3 turns on cathode voltage, and K4 turns on negative pole；When electronic
The interface " L " of bicycle is positive pole " T " when being negative pole, and relay K 5 and K6 works, and K5 turns on cathode voltage, and K6 turns on negative pole,
Thus achieve the conversion of three kinds of distinct interface patterns.Because the coil within relay has the feature of inductance, so working as
When circuit disconnects, coil can produce a induction electromotive force the highest.Therefore to prevent induction electromotive force from damaging circuit
Other original papers or interfere circuit, need in the power supply both sides of relay and connect a diode, in order to consume sensing
Electromotive force.The faintest signal can be amplified by audion, makes so being commonly used to do signal amplification.Because controlling what relay redirected
Signal is sent by photoelectrical coupler, and the control signal that photoelectrical coupler sends is the most weak, is not enough to drive relay, so with three
Control signal is amplified by pole pipe.According to audion, there is " saturated " and the special state of " cut-off ", audion can be used for
Use as switching device.So, control redirecting of relay with audion.In general, the unlatching electricity of silicon type audion
Pressure is about 0.3V, and voltage is less than this value, and audion just enters cut-off state, in order to reliably end, typically to add in base stage
Negative feedback resistor.So being not resulted in relay false tripping to ensure audion energy reliable on off, need the base stage at audion
And between control signal, adding a current-limiting resistance, base stage concatenates a resistance to emitter stage as negative feedback simultaneously.
As it is shown in figure 5, interface convertor of the present invention is connected charger and electric bicycle respectively, conversion can be realized.
