Embodiment
A kind of universal charging interface converter of electric bicycle, unlike the prior art
Including small-power rectifier bridge stack module, power module, photoelectric coupler module, LED lamp module, power rectifier bridge
Heap module and relay module.
The effect of the small-power rectifier bridge stack module is to provide power supply to power module.
The effect of the power module is to provide power supply to photoelectric coupling module and relay module.
The effect of the photoelectric coupler module is that the charging of electric bicycle is obtained from electric bicycle charging interface
Relay module is controlled after the information of mouth mold formula, relay is made to jump to corresponding interface modes.
The effect of the LED lamp module be access electric bicycle charging interface after, converter again with charger
Output interface is connected to each other, and LED lamp module obtains the interface modes of charger from the output interface of charger, and controls LED light just
The really interface modes of instruction charger.As shown in Figure 1, electric bicycle interface modes LED light indicating circuit is by 3 LED light, electricity
Resistance and triode composition.P1 connects with R1, and P2 connects with R2, and P3 is in parallel with R12 after connecting with R3.Because LED light is to belong to two
One kind of pole pipe, so the characteristic of one-way conduction can only be powered and be had with unidirectional current.So only when outN-2 is just
When pole outL-2 is cathode, be just connected marked as the LED light of P1 shinny, it when outL-2 is positive outN-2 is negative similarly to only have
Pole, outL-2 are positive outT-2 when being cathode, be just connected marked as the LED light of P2, P3 it is shinny, in turn then will not be bright.Cause
It is multiplexed for outL-2, and triode serves not only as signal amplification, and switch can also be regarded to use.So triode
It is that hair is just connected in LED light of the cathode in this case marked as P1 that effect, which is in order to ensure there was only outL-2 be positive outT-2,
It is bright, it is ensured that whole LED light can be indicated correctly.
The effect of the power rectifier bridge heap module is to carry out rectification to the electric current that charger exports.
The effect of the 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 shown in Fig. 2, electric bicycle respectively with LED lamp module, photoelectric coupler module, small-power rectifier bridge stack module
It is connected with relay module；Wherein LED lamp module is connect with charger；Wherein photoelectric coupler module connects with relay module
It connects；Its middle low power rectifier bridge stack module is connect with power module, power module respectively with photoelectric coupler module and relay
Module connects；Wherein relay module is connect with power rectifier bridge heap module, and power rectifier bridge heap module connects with charger
It connects.
The photoelectric coupler module is in parallel by three photoelectrical couplers and obtains, each photoelectrical coupler corresponds to detection one
The charging interface pattern of kind electric bicycle.As shown in figure 3, photoelectrical coupler be inside by light emitting diode and phototriode
The device that control is realized by light of composition.Photoelectrical coupler is the device using light as transmission medium, because the transmission of light is not
Public ground wire is needed as the transmission of electric signal, so the circuit of photoelectrical coupler both sides can not altogether.Therefore photoelectricity
The stronger simultaneous transmission efficiency of anti-interference ability of coupler is very high and Comparision is stablized.Three photoelectrical couplers are used as should
The critical piece of partial circuit is used for detecting three kinds of different Interface status respectively.When it is cathode that outN, which is positive outL, light
Electric coupler G1 work and G2 and G3 do not work, when it is cathode that outL, which is positive outN, photoelectrical coupler G2 work and G1 and
G3 does not work, when it is cathode that outL, which is positive outT, and photoelectrical coupler G3 works and G1 and G1 do not work.The effect of resistance is
Photoelectrical coupler current limliting is given, prevents from burning because the electric current for flowing through its inside is excessive.The effect of rectifier diode is to prevent photoelectricity
Coupler, which is reversed breakdown, ensures that the light emitting diode inside device can work normally.The effect of PNP triode be in order to ensure
Only outL is that positive outT- is that photoelectrical coupler G3's cathode just works in this case, it is ensured that optocoupler circuit can be just
Really the state of detection distinct interface, photoelectrical coupler play very important effect in the isolation of circuit output and input.
It ensure that the circuit of these high pressures of outL, outN and outT does not interfere with the normal work of VCC_5V low-voltage circuits part, from
And ensure entire detection module can normal operation.
The power rectifier bridge heap module is made of three power rectifier full-bridges, and each power rectifier full-bridge is just
Pole is all connect with power supply, and cathode is all connect with zero curve, after the output end connection of each power rectifier full-bridge itself, is corresponded to respectively
For L, T, N-port；Two rectifier bridge stacks, which work together, converts a kind of voltage of Interface status, realizes input end interface is different
Dipole inversion is unified for fixed positive and negative polarity.
The relay module uses maximum service rating for 300W, operating voltage 5V, 12V, 24V, 36V or 48V's
Relay.
Relay is commonly used in as a kind of switching device in electronic control circuit, and having can be with the big electricity of Small current control
Stream, low-voltage control high voltage, it is efficient and safe the advantages that.As the present invention important module, relay it is each it is electronic from
It mutually converts between driving interface modes and is played a key role in the work with turning circuit.Two relay co- controllings one
Kind pattern redirects, and uses 6 relays to control redirecting for Three models altogether.As shown in figure 4, when the interface of electric bicycle
" L " is cathode " N " when being anode, and cathode voltage is connected in relay K1 and K2 work, K1, and cathode is connected in K2；Work as electric bicycle
Interface " L " when to be positive " N " be cathode, cathode voltage, K4 conducting cathode is connected in relay K3 and K4 work, K3；When electronic
The interface " L " of bicycle is positive " T " when be cathode, relay K5 and K6 work, and K5 is connected cathode voltage, K6 conducting cathode,
Thereby realize the conversion of three kinds of distinct interface patterns.Because the coil inside relay has the characteristics that inductance, work as
When circuit disconnects, coil will produce a very high induced electromotive force.Therefore induced electromotive force damages circuit in order to prevent
Other original papers interfere circuit, need in the power supply both sides of relay and connect a diode, to consume induction
Electromotive force.Triode can amplify very faint signal, so being commonly used to do signal amplification makes.It is redirected because of relay in order to control
Signal is sent out by photoelectrical coupler, and the control signal that photoelectrical coupler is sent out is too weak, driving relay is not enough to, so with three
Pole pipe will control signal amplification.Triode, can be used for by the special state according to triode with " saturation " and " cut-off "
It is used as switching device.So controlling redirecting for relay with triode.In general, the unlatching electricity of silicon type triode
Pressure is 0.3V or so, and voltage is less than this value, and triode just enters cut-off state and generally to add in base stage to reliably end
Negative feedback resistor.So in order to ensure that triode energy reliable on off without leading to relay false tripping, needs the base stage in triode
Add a current-limiting resistance between control signal, while base stage concatenates a resistance and is used as negative-feedback to emitter.
As shown in figure 5, interface convertor of the present invention is separately connected charger and electric bicycle, you can realize conversion.
