Summary of the invention
The above-mentioned disadvantage that exists for overcoming existing pedal scooter, the purpose of the invention provide a kind of simple and reasonable, operation is light, speed fast, good stability, can body-building can be ridden instead of walk again, both feet are all exerted oneself two three-wheel scooters of stepping on.
The invention solves the problems of the technologies described above the technical scheme that adopts, it comprises handle, standpipe, the front fork sleeve pipe, vehicle frame, front-wheel, hind axle, trailing wheel, described vehicle frame is provided with back wheel driving gear, this device comprises left and right sides stretcher, imput shaft, left and right sides crank, roller, driving gear, driven gear, front sprocket wheel, chain, unidirectional rear sprocket wheel, left and right sides stretcher is hinged on the front portion of vehicle frame, imput shaft is rotating to be arranged on the vehicle frame, left and right sides crank correspondence is fixed on the two ends of imput shaft, roller is separately positioned on the crank of the left and right sides and rolls with corresponding left and right sides stretcher and cooperates, driving gear is fixed on the imput shaft, driven gear and rotating coaxial being arranged on the vehicle frame of front sprocket wheel, unidirectional rear sprocket wheel is installed on the hind axle, driven gear and driving gear engagement, chain is connected between front sprocket wheel and the unidirectional rear sprocket wheel.
In order to guarantee that chain cooperates reliably with the front and back sprocket wheel, described vehicle frame is provided with the expansion tightening wheel that compresses chain, and the pivoted arm of expansion tightening wheel is provided with torsion spring.
For the ease of packed and transported and collection, be connected with Foldable assembly between described front fork sleeve pipe and the vehicle frame.
Safety performance when travelling in order to improve Kickboard Scooter, described handle is provided with the brake handgrip, is hinged with the rear wheel brake sheet that matches with trailing wheel on the vehicle frame, and the rear wheel brake sheet is connected with the brake handgrip by brake cable.
After adopting said structure, have the following advantages compared with the prior art and effect, the one, the user can trample left and right sides pedal by both feet, left and right sides pedal drives driving wheel by crank, driving wheel is by flower wheel and chain-driving hind axle, and hind axle drives trailing wheel and advances, and drive mechanism is simple, travel steadily, riding safety is reliable; The 2nd and since both feet simultaneously firmly and stressed evenly, not only easy and simple to handle, laborsaving during driving, and can greatly improve speed of advance and the ability that continues, both can be used as body-building sports apparatus and used, the walking-replacing tool that can be used as again fashion uses.
