Below in conjunction with accompanying drawing the utility model critical component is described further:

As Fig. 1-shown in Figure 4, the utility model leisure chair car is by car halter 1, electric-control system 2, chair 3, front fork 4, front-wheel 5, Front brake 6, vehicle frame 7, foot pedal apparatus 8, chain 9, hind axle 10, back brake 11 up and down, motor reduction gearbox 12.The foot-operated up and down propulsive effort device 8 of this car is connected on the vehicle frame 7; Foot drive device 8 is by axle bed 81 up and down, connect the anchor shaft 82 that the axially parallel on the axle bed 81 is provided with, and connect respectively the tooth axle 83,83 on two sides ', the nail axle 84 of vertical direction, connect turning cylinder 85, be connected the bevel gear 86 on the nail axle 84, be connected on the anchor shaft 82 step on handle 87,87 ' and pedal 88,88 ', be connected the gear 89,89 at two ends on the turning cylinder 85 ' and overriding clutch 90,90 ', an end of turning cylinder 85 also connects sprocket wheel 91 and constitutes; Bevel gear 86 mesh respectively step on handle 87,87 ' on umbrella tooth piece, step on handle 87,87 ' on the straight-tooth piece respectively engaging tooth axle 83,83 ' on miniature gears, tooth axle 83,83 ' on big gear wheel engaging gear 89,89 ' and overriding clutch 90,90 ' action respectively.Step in addition handle 87,87 ' and umbrella tooth piece and straight-tooth piece be all one respectively.Tooth axle 83,83 ' and big gear wheel, miniature gears be all one respectively.Overriding clutch 90,90 ' on have respectively gear 89,89 '.Also having on the electrical motor has gear reduction box to be connected with hind axle, in an embodiment in order to reduce friction drag, in rotation place graphite oilless sintered-metal bearing and antifriction-bearing box is arranged all certainly.

The effect operational process of this car is such: when people's foot pedal 88 downward, step on umbrella tooth piece on the handle 87 drive bevel gear 86 and step on handle 87 ' on the swing of umbrella tooth piece, make pedal 89 ' upwards, by step on handle 87 ' on the straight-tooth piece drive tooth axle 83 ' on miniature gears, and by tooth axle 83 ' on big gear wheel driven gear 89 ', it turns to and can make overriding clutch 90 ' automatically throw off, idle running.And the miniature gears on the straight-tooth piece drive tooth axle of stepping on the handle 87 83, and by the big gear wheel driven gear 89 on the tooth axle 83, it turns to and can make overriding clutch 90 automatic combinations, drives turning cylinder 85 and sprocket wheel 91 rotations, pass to flywheel on the hind axle 10 by chain 9, wheel is rolled forward.Same principle: when people's foot pedal 88 ', sprocket wheel 91 is rotated, so two top-cross for foot pedal 88,88 ', just can make wheel rolling forward continuously.Also can directly drive wheel by motor reduction gearbox 12 in addition rolls forward.When car retreats, turning cylinder 85 counter-rotatings, it turns to and can make two overriding clutchs 90,90 ' disengagement automatically, idle running.
