The specific embodiment

Below by drawings and Examples the technical solution of the utility model is described in further detail.

Contrast Fig. 1, Fig. 2, Fig. 3, Fig. 4, the foot-operated up and down scooter that drives described in the utility model is by handle component before the car 1, handrail 2, front-wheel 3, link slot 4, car pedal 5, pedal shaft 6, stretcher supporting blade 7 (two), tooth bar 8 (two), vehicle frame 9, hinge wheel 10, bicycle freewheel 11 (two), flywheel sleeve 12 (two), chain 13, trailing wheel 14 (two), minor sprocket 15, retracing spring 16 (two), flywheel shaft support 17 (two), bracket of back axle 18 (two), flywheel shaft 19, rear axle 20, stretcher 21 (two), stretcher axle sleeve 22 (two) is formed.

During use, the people stands onboard, and the both hands walker is 12, and bipod is placed on respectively on two stretchers 21, and the car pedal is being stepped in pin the place ahead, and body support, heel lift along the angle of inclination of stretcher 21 and put down gently.A pin is temporarily motionless, the heel of another pin is firmly down stepped on, stretcher 21 and be connected following stretcher supporting blade 7 and also have tooth bar 8 then toward pressing down, at this moment, it is the center of circle with the axle center of pedal shaft 6 all that stretcher 21, stretcher supporting blade 7 also have tooth bar 8, carry out loose-leaf system and rotate, loose-leaf system rotates and has just rotated certain angle; Retracing spring 16 is stretched in current the rotation.In rotation, the teeth of tooth bar 8 drive and its ingear bicycle freewheel 11 rotates, and the rotation of bicycle freewheel 11 is stressed rotations, and it drives flywheel sleeve 12 and rotates together, and flywheel sleeve 12 drives flywheel shaft 19 rotations; The rotation of flywheel shaft 19 also drives hinge wheel 10 and rotates; The chain 13 drive minor sprockets 15 that are enclosed within on the hinge wheel 10 rotate, and after minor sprocket 15 is driven, drive the rear axle 20 that is fixed together with it again and rotate, and rear axle 20 also drives the trailing wheel 14 that is fixed on above it and rotates, thereby whole car is advanced.

When unclamping stretcher 21, be connected retracing spring 16 retracted for clearance under the effect of elastic force on the tooth bar 8, make stretcher 21, stretcher supporting blade 7 and tooth bar 8 upwards return to the home position, prepare to trample next time.The recovery principle is: when stretcher 21 upwards recovers, drive tooth bar 8 upward movements, the teeth of this hour rack 8 drive bicycle freewheel 11 counter-rotation (reversing sense of bicycle freewheel 11 is meant: opposite with the direction that bicycle freewheel 11 rotates when down stepping on stretcher 21 just now).Because bicycle freewheel 11 during counter-rotation, is the idle running that does not stress,, therefore do not influence the original hand of rotation of flywheel shaft 6 and a series of associated components that link together so can not drive flywheel sleeve 12 and flywheel shaft 6 counter-rotation.

Its main effect is exactly, and when trampling, under the effect of power, by a series of mechanical movements, car advanced downwards, and when unclamping stretcher 21, power can not act on the car, can opposite effect power not arranged to car, does not influence the original service direction of car.

The user steps stretcher 21 in turn by both feet, user's strength is become drive the power that car advances, and impels the car motion.
