Description
The utility model relates to a kind of morpet, particularly a kind of intelligent electric boosted bike.
At present, the Electrical Bicycle of selling on the domestic and international market mostly is greatly that brush direct current motor (accounting for 90%) and dc brushless motor (10%) and control setup thereof drive, and the power-assisted type of drive mostly is mechanical type, promptly determines the power-assisted ratio with mechanical system.Main developed country bans use of all-electric bicycle legally, and all-electric bicycle is included into the battery-operated motor cycle field in the world.The defective of brush direct current motor is: 1) brush life is limited, needs periodic cleaning brush powder or changes brush; 2) because of motor moment high temperature or the vibrations of travelling of Electrical Bicycle can cause the demagnetization of permanent magnet or come off; 3) because the demagnetization of permanent magnetism and the spark of commufafor make it to be difficult to directly start from quiescence, generally needing manpower to pedal after 3～5 kilometers/hour (printed wiring formula brush direct current motors) could starter motor; 4) because the commufafor spark is difficult to speed-raising and cost height.The defective of dc brushless motor is: 1) vibrations of travelling of the high temperature of electric motor starting moment or Electrical Bicycle can cause the demagnetization of permanent magnetism or come off; 2) owing to the centrifugal action of rotor, speed-raising is subjected to certain restriction; 3) capacity motor is restricted, and the cost height.More than the deadly defect of two kinds of drive motor are poor stability, traveling comfort and durability not insufficient, efficient is low, power consumption is big, the cost height.
The purpose of this utility model is at the deficiencies in the prior art and defective, a kind of intelligent electric boosted bike that adopts the asynchronous squirrel-cage motor of low-voltage three-phase AC is proposed, it can improve safety, traveling comfort, motor combined efficiency, increases the flying power of once charging under equal capacity of cell, and reduces manufacturing cost.
The purpose of this utility model is achieved through the following technical solutions.
A kind of intelligent electric boosted bike, it comprises front-wheel, trailing wheel, handlebar, vehicle frame, pedal, double-stranded bar, seat, back vehicle frame, retarder, speed sensor, pedaling force sensor, electromagnetic braking switch and battery, and intelligence control system, it is characterized in that it has adopted an asynchronous squirrel-cage motor of low-voltage three-phase AC.
The asynchronous squirrel-cage motor of described low-voltage three-phase AC uses the 12V three phasevoltage.
Described retarder is efficient spiral bevel gear retarder.
Described pedaling force sensor only is the chain tension switch.
The asynchronous squirrel-cage motor of 12V low-voltage three-phase AC under DC24V maintenance-free battery power supply, as propulsion source, the auxiliary manpower bicycle of riding.Pedaling force sensor is sent the legpower signal into intelligence control system, carries out by the output torque of the asynchronous squirrel-cage motor of inverter control low-voltage three-phase AC, implementing power-assisted after power-assisted calculates.
The utility model compared with prior art has the following advantages: 1) improved traveling comfort, safety and motor combined efficiency greatly; 2) under equal capacity of cell, increased the flying power of once charging; 3) reduced manufacturing cost, be convenient to promote; 4) noise is little, and is energy-conservation.
Accompanying drawing 1 is the scheme drawing of intelligent electric boosted bike.
Embodiment:
Introduce a kind of intelligent electric boosted bike in conjunction with the accompanying drawings, it comprises front-wheel 1, trailing wheel 2, handlebar 3, vehicle frame 4, pedal 5, double-stranded bar 6, seat 7, back vehicle frame 8, retarder 10, speed sensor 11, pedaling force sensor 12, electromagnetic braking switch 13 and battery 14, and intelligence control system 15, it has adopted an asynchronous squirrel-cage motor 9 of low-voltage three-phase AC.
The asynchronous squirrel-cage motor of low-voltage three-phase AC 9 uses the 12V three phasevoltages, carries out vector controlled, under DC24V maintenance-free lead acid colloid battery 14 (12V5Ah * 2) power supply, and as propulsion source, the auxiliary manpower bicycle of riding.
Retarder 10 is efficient spiral bevel gear retarder, and speed ratio is 1: 5.86.
Pedaling force sensor 12 only is the chain tension switch.
Pedaling force sensor 12 is sent the legpower signal into intelligence control system, carries out by the output torque of the asynchronous squirrel-cage motor of inverter control low-voltage three-phase AC, implementing power-assisted after signal conditioning and power-assisted calculate.Pacifically under the state, maximum speed was defined as 24 kilometers/hour to this intelligent electric boosted bike 1: 1 power-assisted, hill climbing ability≤10 °, flying power 〉=70 kilometer of once charging.This intelligent electric boosted bike is ridden fool proof, comfortable, and power-assisted sensation obviously and can be set the power-assisted ratio arbitrarily, and it is little also can to carry out electromagnetic braking (brake) noise, and low cost of manufacture is easy to popularization.
