Input end grounding.
Two output ends of optocoupler part connect+brake cable and-brake cable respectively when use, and first diode anode connects motor phase
Line.
The beneficial effects of the utility model are: to click acknowledgement key electric vehicle could travel, operator can be allowed to understand
Understanding oneself operation behavior, avoid carelessness, hurry in the raw generations such as disorderly safety accident.And circuit structure is simple, function
Consume extremely low, the service life is long, safe and reliable.
Detailed description of the invention
The utility model will be further described with reference to the accompanying drawing.
Fig. 1 is the electrical structure schematic diagram of the utility model.
Specific embodiment
Referring to attached drawing, a kind of electric vehicle driving safety confirmation switch of the utility model, it is characterised in that: first diode D1
Anode connects signal wire, and cathode connects confirmation switch K first end, first capacitor C1 first end, 3rd resistor R3 first end and the 4th electricity
R4 first end is hindered, it is negative that confirmation switch K second terminates first resistor R1 first end, the 8th resistance R8 first end and the second diode D2
Pole, the second diode D2 anode connect power supply, and first resistor R1 second terminates second resistance R2 first end and PNP type triode V1 base
Pole, PNP type triode V1 emitter connect 3rd resistor R3 second end, the 4th resistance R4 second end and the 7th resistance R7 first end and
5th resistance R5 first end connects, and the 5th resistance R5 second terminates adjustable resistance RP first end, and the 7th resistance R7 second terminates NPN
Type triode V2 base stage, NPN type triode V2 collector connect the 8th resistance R8 second end and optocoupler part U1 positive input terminal, the second electricity
Resistance R2 second end, PNP type triode V1 collector, first capacitor C1 second end, adjustable resistance RP second end and centre tap,
NPN type triode V2 emitter and optocoupler part U1 negative input end ground connection.
Acknowledgement key K is mounted on right hand handle nearby inactive portion and the light accessible position of right thumb energy.Signal wire connects
Any phase line of motor.High brake type brake cable "+" pole connects the direct current or former vehicle brake supply lines of adaptation, and ' "-" pole connects brake cable
The high power-off line of stopping of controller for electric vehicle；Low brake type brake cable "+" pole connects the low brake power-off line anode of controller for electric vehicle, brake
Line "-" cathode connects controller for electric vehicle cathode.
Power supply, motor phase line (signal wire) no current are opened, triode V2 is not turned on, and the pole C of V2 exports high level, light
Coupling U1 must be conducted, the positive and negative conducting of brake cable, motor power-off.
Acknowledgement key K is clicked, capacitor C1 charging and moment pass through partial pressure shunt resistance and V2 are connected, and the pole C of V2 exports low electricity
Flat, optocoupler U1 power loss cut-off, the positive and negative disconnection of brake cable, motor waits for electricity.
It rotates and handle motor is accelerated to obtain electric electric vehicle traveling, any phase line output electric current of motor adds after diode D1 rectification
Capacitor C1 is continued on signal wire to charge and continue conducting V2, continues previous step, the positive and negative disconnection of brake cable, motor obtains electric.
It unclamps electric vehicle and accelerates handle, motor power-off, the input of signal wire no current, but the electricity of capacitor C1 storage continues to
Turn-on transistor V2 20 seconds or so (can be adjusted by resistance RP), motor continued to standby to electricity at this time, when capacitor C1 electricity
For amount consumption to when being not enough to that V2 is connected, optocoupler U1 obtains electricity output conducting, the positive and negative conducting of brake cable, motor power-off.
It powering off, the electricity of capacitor C1 discharges rapidly the charge of capacitor C1 by suitable resistance, it is again switched on power supply,
System returns to original state.
It that is acknowledgement key K will be clicked, can travel, be more than setting time without correct efficient operation, it is necessary to press again
Once acknowledgement key could start motor.
The utility model can allow clearer oneself the operation behavior of understanding of operator, and clicking acknowledgement key K could go
Sail, rotate acceleration handle in traveling in 20 seconds, for example slip long slope and nor affect on normal operation behavior, this with this is not installed
The electric vehicle of device does not rotate acceleration handle without any difference after 20 seconds, that is, without operational motion, electric vehicle motor is powered off,
Rethink starting motor, it is necessary to click acknowledgement key.
Electric vehicle is mute when stopping, and due to various reasons, operator may not power off in time, if installing this hair additional
Bright device is just avoided that those are careless, hurries middle raw random, foreign object interferes and others is not intended to touching, and child plays and gets acceleration
Handle goes out electric vehicle rapidly, has also just prevented the safety accident generated by such case even great personal injury and wealth
Produce loss.Also as must sometimes click acknowledgement key, so operator can also be allowed to become apparent from oneself traveling behavior, with
When it is watchful, rectify posture, also can effectively reduce other safety accidents.
