Description
Technical field
A kind of circuit is the utility model is related to, particularly a kind of electric car rate-limiting control circuit.
Background technology
Electric car, i.e. electric drive vehicle, also known as electricity are driven.Electric car is divided into alternating current electric vehicle and DC electric car.Generally
The electric car said is using battery as energy source, by parts such as controller, motors, converts electrical energy into mechanical energy motion,
Change the vehicle of speed with control electric current size.With electric car development it is varied, electric car function is also constantly being lifted,
But existing electric car, only speed-regulating function, when electric car is being run at high speed, driving can be caused in the case of brake suddenly,
Which adds the danger of electric car trip.
The content of the invention
The purpose of this utility model is to provide a kind of electric car rate-limiting control circuit, and circuit connection is simple, works as electric car
When running at high speed, reach the purpose of limitation speed.
To achieve the above object, the technical solution adopted in the utility model is：A kind of electric car rate-limiting control circuit, resistance
R8-1 one end ground connection, one end with resistance R8-2, resistance R10-1 one end are connected its other end respectively, and resistance R10-1's is another
One end is connected with diode D6 negative pole, resistance R80 one end, electric capacity C11 one end, handle power supply, resistance R8-2's
The other end connects the port 1 of control chip, and diode D6 positive pole connects after being connected with the resistance R80 other end with 5V dc sources
Mouth connection, electric capacity C11 other end ground connection, the port 2 of the control chip connects resistance R8 one end, the one of resistance R10-2
End and electric capacity C5 one end, electric capacity C5 other end ground connection, resistance R8 other end connection handle rate signal, the one of resistance R9
End, resistance R9 other end ground connection, the resistance R10-2 other end are connected with speed limit selection line.
Further, the model STC15F2K16S of the control chip.
The beneficial effects of the utility model are：When speed limit selection line is with negative pole short circuit, speed handle voltage signal will be electric
R8 and resistance R10-2 pro rata distributions are hindered, voltage scale declines in Acquisition Circuit, so as to reach the purpose of rate limitation；Turn
The detection of power supply, whether working properly, prevent vehicle abnormality from starting if can react handle；Circuit connection is simple, works as electric car
When running at high speed, reach the purpose of limitation speed, bicyclist is driven safely during trip.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, the technical solution adopted in the utility model is：A kind of electric car rate-limiting control circuit, resistance R8-1
One end ground connection, one end with resistance R8-2, resistance R10-1 one end are connected its other end respectively, the resistance R10-1 other end
Negative pole, resistance R80 one end, electric capacity C11 one end, handle power supply with diode D6 are connected, and resistance R8-2's is another
The port 1 of end connection control chip, diode D6 positive pole be connected with the resistance R80 other end after with 5V dc power interfaces company
Connect, electric capacity C11 other end ground connection, the port 2 of the control chip connect resistance R8 one end, resistance R10-2 one end and
Electric capacity C5 one end, electric capacity C5 other end ground connection, resistance R8 other end connection handle rate signal, resistance R9 one end,
Resistance R9 other end ground connection, the resistance R10-2 other end are connected with speed limit selection line.
Further, the model STC15F2K16S of the control chip.
During work, when speed limit selection line is with negative pole short circuit, speed handle voltage signal will be pressed by resistance R8 and resistance R10-2
Pro rata distribution, voltage scale declines in Acquisition Circuit, so as to reach the purpose of rate limitation；The detection of handle power supply, can be anti-
Answer handle whether working properly, prevent vehicle abnormality from starting；When handle rate signal transmits 0.7,4.2 hair, by resistance R8
Control chip is passed to, when speed limit selection line and negative pole short circuit, handle rate signal need to enter by resistance R8, resistance R10-2
Row partial pressure passes to control chip, and at this moment control chip can only collect 0.35V, 2.1V voltage, so as to reach the mesh of speed limit
's；Control chip is monitored to handle power supply 5V power supplys, when 5V power supplys collection value will not stop in estimated range, control chip
Motor rotates, and carries out preventing driving from protecting；Internal 5V power supplys pass through electricity by feed speed handle after diode D6
After hindering R8, resistance R10-2 signal partial pressures, control chip is sent to, carries out 5V voltage signal acquisitions.
