Description
Technical field
The utility model belongs to electric automobiles, particularly relates to a kind of novel electric vehicle circuit.
Background technology
Electrical Bicycle, refers to using storage battery as auxiliary energy on the basis of ordinary bicycle, has installed the Personal Transporter of the electromechanical integration of the control members such as motor, controller, storage battery, handle brake lever and display instrument system." Chinese Electrical Bicycle re-invent industry summit forum " data display in 2013, Chinese Electrical Bicycle ends recoverable amount in 2013 and breaks through 200,000,000.And the Electrical Bicycle " new national standard " be among dispute also will be put into effect always.New national standard is estimated to start a large change in Electrical Bicycle industry.
Battery-driven car mainly comprises:
Charger
Charger is to the device of battery electric energy supplement, general point two-stage charge mode and Three stage mode two kinds.Two-stage charge mode: first constant-voltage charge, charging current reduces gradually with the rising of cell pressure, and wait battery electric quantity to add to a certain degree, cell pressure can rise to the setting value of charger, is now converted to trickle charge.Three stage charge modes: when charging starts, first constant-current charge, gives battery makeup energy rapidly; Transfer constant-voltage charge to Deng after cell pressure rising, now the energy content of battery is slowly supplemented, and cell pressure continues to rise; When reaching the end of charge voltage value of charger, transfer trickle charge to, to maintain the self-discharge current of battery and supply battery.
Battery
Battery be to provide electric vehicle energy with the car energy, battery-driven car mainly adopts lead-acid battery to combine.Ni-MH battery and lithium ion battery also have come to use on some Portable foldable electric motorcars in addition.
Use prompting: controller master control board is battery-driven car major loop, has larger working current, can send larger heat.Therefore, battery-driven car is not parked and is tanned by the sun in the sun, does not drench with rain for a long time, in order to avoid controller is out of order yet.
Controller
Controller controls the parts of motor speed, is also the core of electric car electrical system, has under-voltage, current limliting or overcurrent protection function.Intelligent controller also has multiple ride mode and car load electric component self-checking function.Controller is the core component of electric vehicle energy management and various control signal process.
Handle, brake lever
Handle, brake lever etc. are the signal input parts of controller.Handle signal is the drive singal that electric vehicle motor rotates.Brake lever signal is when electric vehicle brake, and brake lever internal electronics exports to an electric signal of controller; After controller receives this signal, the power supply to motor will be cut off, thus realize brake power down function.
Assistant sensor
Assistant sensor is detect pedal power bend backwards of riding to pedal the device of speed signal when battery-driven car is in power-assisted state.Controller, according to electric drive power, with bicycle torque sensor, reaches manpower and electric power Auto-matching, and the common battery-driven car that drives rotates.At present the assistant sensor of most trend is axis double-side torque sensor, and its products characteristics is the pedal force that can gather the right and left, and adopts contactless electromagnetic signal acquisition mode, thus improves particularity and the reliability of acquisition of signal.
Motor
The most important accessory of Electrical Bicycle is motor, and the motor of an Electrical Bicycle determines performance and the class of this car substantially.The motor that Electrical Bicycle uses is mostly efficient rare-earth magneto-electric machine, and wherein mainly dividing again has brush teeth+wheel reducing motor, low speed brush motor and low-speed brushless motor three kinds at a high speed.
In the scheme realizing prior art, find that prior art exists following technical matters:
The loudspeaker of existing battery-driven car can only be blown a whistle, and cannot carry out music, so user's susceptibility is low.
Utility model content
The object of the utility model embodiment is to provide a kind of novel electric vehicle circuit, and it mainly solves the problem that existing battery-driven car does not have music.
The utility model provides a kind of novel electric vehicle circuit, and described circuit comprises: audio amplifier, coil, microprocessor and bluetooth module; Wherein, microprocessor is connected with one end of K switch 1, and the other end of K switch 1 connects the signal input part of audio amplifier; One end that the negative lead circle of audio amplifier is elementary connects, the other end of coil primary connects the positive pole of audio amplifier, one end of coil primary is also connected with one end of resistance R1, the other end of electric capacity R1 is connected with one end of electric capacity C1, the other end of electric capacity C1 connects the positive level of diode D1, and the cathode of diode D1 connects power cathode; The positive level of diode D1 goes back the emitter of connecting triode T1, and the base stage of T1 is connected with one end of electric capacity C1, one end that the emitter connecting coil of T1 is secondary, another termination positive source that coil is secondary; Treater is also connected with bluetooth module.
Optionally, described novel electric vehicle circuit also comprises: SD draw-in groove, and this SD draw-in groove is connected with microprocessor.
In the utility model embodiment, the technical scheme that the utility model provides adds bluetooth module, and such user can carry out music by external equipment on battery-driven car, such as, carry out music by mobile phone.
