Abstract
The utility model relates to an intelligent motor-boosted wheel chair which comprises a front wheel 1, a rear wheel 2, a bicycle handle 3, a frame 4, pedals 5, a double chain 6, a seat 7 and a rear bicycle frame 8, and also a three-phase alternating current asynchronous motor 9 which is in a squirrel cage shape and has a low voltage of 12 V, a curved teeth bevel gear reducer 10 high efficiency, a speed sensor 11, a hand swinging force sensor 12 only for switching a chain tension, an electromagnetic brake switch 13, an overall electrodynamic mode switch 14, a battery 15 and an intelligent control system 16. The utility model can be electrically and intelligently boosted with obviously sensed boosting force, and a boost ratio can be set arbitrarily; the utility model can be fully automatically driven to run comfortably and safely; the overall efficiency of the motor is improved, so the utility model can be charged only one time to run continuously with less energy, low noise and low cost.
Description
This utility model relates to a kind of electric boosted tricycle for the disabled, particularly a kind of intelligent electric boosted tricycle for the disabled.
At present, the electronic tricycle for the disabled of selling on the domestic and international market mostly is the all-electric mode that brush direct current motor (about 90%) and dc brushless motor (10%) and control device thereof drive.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 electronic tricycle for the disabled can cause the demagnetization of permanet magnet or come off; 3) owing to need directly start,, cost is improved so bigger motor surplus will be arranged from resting state.The defective of dc brushless motor is: 1) vibrations of travelling of the high temperature of electric motor starting moment or electronic tricycle for the disabled 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 motors are poor stability, comfortableness 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 tricycle for the disabled is proposed, it can improve safety, comfortableness, motor overall efficiency, increases the flying power of once charging under equal battery capacity, and reduces manufacturing cost.
The purpose of this utility model is achieved through the following technical solutions.
A kind of intelligent electric boosted tricycle for the disabled, it comprises front-wheel, trailing wheel, handlebar, vehicle frame, wind, double-stranded bar, seat, back vehicle frame, it is characterized in that it also comprises the asynchronous squirrel-cage motor of low-voltage three-phase AC, decelerator, velocity sensor, hand force transducer, electromagnetic braking switch, all-electric mode switch and a battery, and intelligence control system.
The asynchronous squirrel-cage motor of low-voltage three-phase AC uses the 12V three-phase voltage.
Decelerator is efficient spiral bevel gear decelerator.
Hand force transducer only is the chain tension switch.
The asynchronous squirrel-cage motor of 12V low-voltage three-phase AC is under the power supply of DC24V maintenance-free battery, and as power source, auxiliary manpower is sat the row tricycle for the disabled.Hand force transducer will shake the force signal intelligence control system of making a gift to someone, and carry out by the output torque of the asynchronous squirrel-cage motor of inverter control low-voltage three-phase AC, implementing power-assisted after signal processing and power-assisted calculate, also can be under all-electric pattern all-electric travelling.
This utility model compared with prior art has the following advantages: 1) improved comfortableness, safety and motor overall efficiency greatly; 2) under equal battery capacity, 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 sketch map of intelligent electric boosted tricycle for the disabled.
Embodiment:
Introduce a kind of intelligent electric boosted tricycle for the disabled in conjunction with the accompanying drawings, it comprises front-wheel 1, trailing wheel 2, handlebar 3, vehicle frame 4, wind 5, double-stranded bar 6, seat 7, back vehicle frame 8, it also comprises the asynchronous squirrel-cage motor 9 of low-voltage three-phase AC, decelerator 10, velocity sensor 11, hand force transducer 12, electromagnetic braking switch 13, all-electric mode switch 14 and a battery 15, and intelligence control system 16.
The asynchronous squirrel-cage motor 9 of low-voltage three-phase AC uses the 12V three-phase voltage, carry out vector controlled, under DC24V maintenance-free lead acid colloid battery 15 (12V12Ah * 2) power supply, as power source, auxiliary manpower shakes capable tricycle for the disabled, or under all-electric pattern all-electric travelling.
