The height of trailing wheel 22 wheel hubs and the ratio of diameter are 2: 1, make the front and back center of gravity of scooter keep balance.
The operation principle of this foot-controlled electric scooter:
Direction-control apparatus: when straight-line travelling, driver's both feet are placed on the wide placing device 23 of castor.In the time that driver needs toward left steering, left foot heel is stepped on the friction striped of the wide placing device 23 of castor, and tiptoe moves to left on pedal 1 taking heel as the center of circle.While stepping on left to pedal 1, power is passed to left tooth bar 6, left tooth bar 6 down slidings, and the back-moving spring 20 in left side compresses.Left tooth bar 6 engages with left gear 7, and left gear 7 engages rotation with idler gear 9, and idler gear 9 engages rotation with right gear 11, and right tooth bar 13 engages upward sliding with right gear 11, and the back-moving spring 20 on right side stretches.Tooth sector 14 drives steering rack 15 levels to slide left, and steering control level 16 is rotated counterclockwise around abutment sleeve 29 by turnbarrel connecting rod 17 driven rotary sleeves 18, thereby two front-wheels 19 turn left, and scooter is realized left steering.In left steering process, back-moving spring 20 decrements in left side are identical with back-moving spring 20 amount of tension on right side, in the time that scooter finishes to turn to, driver lifts left foot, retract on the wide placing device 23 of castor, left is homing under 20 effects of corresponding back-moving spring to pedal 1 and right pedal 2, and scooter continues straight-line travelling forward.In like manner, when driver needs toward right turn, right crus of diaphragm heel is stepped on the friction striped of the wide placing device 23 of castor, and tiptoe moves on right pedal 2 taking heel as the center of circle.While stepping on right pedal 2, power is passed to right tooth bar 13, and the back-moving spring 20 on right side compresses.Right tooth bar 13 engages with right gear 11, and right gear 11 engages rotation with idler gear 9, and idler gear 9 engages rotation with left gear 7, and left tooth bar 6 engages upward sliding with left gear 7, and the back-moving spring 20 in left side stretches.Tooth sector 14 drives steering rack 15 levels to slide to the right, and steering control level 16 turns clockwise around abutment sleeve 29 by turnbarrel connecting rod 17 driven rotary sleeves 18, thereby two front-wheels 19 turn right, and scooter is realized right turn.In right turn process, back-moving spring 20 decrements on right side are identical with back-moving spring 20 amount of tension in left side, in the time that scooter finishes to turn to, driver lifts right crus of diaphragm, retract on the wide placing device 23 of castor, left is homing under 20 effects of corresponding back-moving spring to pedal 1 and right pedal 2, and scooter continues straight-line travelling forward.
Power accelerator: while normally travelling, driver's both feet are placed on the wide placing device 23 of castor.In the time that scooter accelerates, driver's right crus of diaphragm heel is stepped on the friction striped of the wide placing device 23 of castor, and tiptoe moves on gear shift pedal 3 taking heel as the center of circle.While stepping on gear shift pedal 3, push rod 31 is along push rod housing 28 down slidings, and return spring 27 compresses, and contact switch 30 is activated; Slide down to along push rod housing 28 at push rod 31 in the process of range, from large to small, the electric current in control circuit changes from small to big the resistance of slide rheostat, and wheel hub motor rotating speed accelerates, and realizes accelerator.In the time that scooter finishes to accelerate, driver lifts right crus of diaphragm, retracts on the wide placing device 23 of castor, and the restoring force of return spring 27 promotes treadle supporting piece 26 and gear shift pedal 3 returns to elemental height automatically.The dynamics that driver can trample gear shift pedal 3 according to right crus of diaphragm is controlled the acceleration degree of scooter.
Slow down and brake apparatus: while normally travelling, driver's both feet are placed on the wide placing device 23 of castor.In the time that scooter slows down or brakes, driver's left foot heel is stepped on the friction striped of the wide placing device 23 of castor, and tiptoe moves on gear shift pedal 3 taking heel as the center of circle.While stepping on gear shift pedal 3, return spring 27 compresses, contact switch 30 is activated, slide down to along push rod housing 28 in the process of range at push rod 31, displacement transducer obtains the positional information of gear shift pedal 3 by detecting the displacement of push rod 31 down slidings, control circuit is according to the positional information of gear shift pedal 3, output pwm signal, according to the change of wheel hub motor rotor hall sensor signal, select the conducting sequential of " three-phase six-beat ", the IGBT power tube output reversing the current that conducting is corresponding, the time of IGBT power tube conducting is longer, reversing the current value is larger, wheel hub motor rotating speed is slower, realize moderating process.The dynamics that driver can trample gear shift pedal 3 according to left foot is carried out the size of output pwm signal control reversing the current.In the time that driver need to make scooter slowly slow down, only need step on 1/3rd of gear shift pedal 3, the time of IGBT power tube conducting is shorter, and the reversing the current of control circuit output is less; In the time that driver need to make scooter slow down fast, can step on 2/3rds of gear shift pedal 3, the time of IGBT power tube conducting is relatively long, and the reversing the current that control circuit output is larger is realized fast and being slowed down; In the time that driver need to make scooter brake immediately, can step on gear shift pedal 3 to range, the conducting always of IGBT power tube is until scooter stops, and control circuit is exported specified maximum reverse current, realizes braking immediately.
