The pedal-crank driving mechanism adopts the structure that two cranks, pedals and pedal levers are respectively arranged on left and right sides; one end of each crank is driven by a ratchet wheel transmission mechanism to drive the rear wheels to rotate; the other end of each crank is connected with the rear end of the pedal through a steel wire; the front end of the pedal is connected with the scooter beam through the pedal lever; and the front end and the rear end of the pedal lever are respectively hinged with the scooter beam and the pedal. The scooter has simple structure, adopts the pedal-crank driving mechanism, and is more practical and durable.
Description
Technical field
The utility model relates to a kind of scooter.
Technical background
Children's the unpowered mechanism of the Kickboard Scooter of playing, really not too practical as walking-replacing tool; The actuating unit of bicycle is comparatively complicated again, therefore, also is out of order easily; The Folding Bicycle volume is still bigger, is not easy to carry at any time.Therefore, be necessary to design a kind of more practical bicycle.
The utility model content
Technical problem to be solved in the utility model is to propose a kind of scooter, and this scooter arrangements is simple, employing pedal-crank-drive mechanism, and is more practical, more durable.
Technical solution of the present utility model is as follows:
A kind of scooter comprises tap, car beam, front-wheel, trailing wheel and back vehicle frame, and trailing wheel is arranged on the lower end of back vehicle frame, and back vehicle frame is arranged on the rear end of car beam, and the driver train of scooter is pedal-crank-drive mechanism.
Described pedal-crank-drive mechanism is: about crank, pedal and treadle are each one, one end of 2 cranks drives the trailing wheel rotation by transmission device, the other end of 2 cranks connects the rear end of pedal by steel wire, the front end of pedal connects the car beam by treadle, and the front-end and back-end of treadle are hinged with car beam and pedal respectively.
Two cranks are separately fixed at the left and right sides of the rotating shaft of trailing wheel.
Rotating shaft is connected with the wheel hub of trailing wheel by ratchet, and rotating shaft is connected with the back vehicle frame by bearing-bearing frame.
The rear end of car beam is provided with brake pedal.
The car beam is made up of for two sections front and back, and two sections joint portion is provided with and is used for the folding means that the car beam is folding in the front and back of car beam.Beneficial effect:
Scooter arrangements of the present utility model is simple and reliable, and the operation quick and stable meets human cinology's principle.Descend 2/3 than bicycle fault rate, weight reduces 1/3rd, can fast folding, and design size hour is carried in the bag of can packing into.In scooter advances process, as danger, can finish man-machine separation moment, safety is good, and the adaptation population is wide, and productive costs is low.

The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
Embodiment 1:
As Fig. 1, a kind of scooter comprises tap, car beam, front-wheel, trailing wheel and back vehicle frame, and trailing wheel is arranged on the lower end of back vehicle frame, and back vehicle frame is arranged on the rear end of car beam, and the driver train of scooter is pedal-crank-drive mechanism.Described pedal-crank-drive mechanism is: about crank, pedal and treadle are each one, one end of 2 cranks drives the trailing wheel rotation by transmission device, the other end of 2 cranks connects the rear end of pedal by steel wire, the front end of pedal connects the car beam by treadle, and the front-end and back-end of treadle are hinged with car beam and pedal respectively.As Fig. 2, two cranks are separately fixed at the left and right sides of the rotating shaft of trailing wheel.Rotating shaft is connected with the wheel hub of trailing wheel by ratchet, and rotating shaft is connected with the back vehicle frame by bearing-bearing frame.The rear end of car beam is provided with brake pedal.
The car beam is made up of for two sections front and back, and two sections joint portion is provided with and is used for the folding means that the car beam is folding in the front and back of car beam.Also be provided with fold mechanism on tap, this fold mechanism and these parts are identical with the fold mechanism structure and the principle of traditional folding bicycle, belong to existing mature technology.
Fig. 3 discloses the principle of work of this scooter, establishes the long n of being of left and right sides pedal, the long m of steel wire, there is a necessary condition in long l of crank and axle center 9 to the long h of rear axis, n+m=l+h, and two cranks are mutually 180 degree, when left-hand tread plate when the nadir, right-hand tread plate is to vertex, and just crosses above-mentioned condition line.A mechanics principle is arranged here, this is a parallelogram diagram of component forces, establishes G and is people's body weight, when α=180 °, F1 and F2 pulling force are the several times of G, because this power effect time is short and power is big, claim on the physics that momentum mv=Ft is big again, momentum moment is big, force of explosion is strong, momentum is big, so inertia is big, can ensure that the scooter kinematic velocity is fast.
This car movement characteristic: stance motion, thereby pedal both had been used to support manned, was again power plate.When stepping on left foot, right crus of diaphragm must be taken advantage of a situation and be lifted, and leaves pedal, and vice versa, up and down reciprocatingly, drives car body and human body and advances.
Braking vane adopts the spring steel plate punch forming, and pin steps down in oppresses car foreign steamer generation friction with braking above the braking vane.
In this example: vehicle commander 1100mm, wheel footpath 300mm, overall height 1200mm, folding back length/width/high parameter is: 650/320/90, unit is a millimeter.
The working process explanation: depress pedal drive steel wire pulling crank earlier and make rotating shaft rotate, rotating shaft is by the ratchet drives trailing wheel, and under the effect of ratchet, trailing wheel can only just change and can not reverse.
