Description

A kind of pedal-type scooter

Technical field

The utility model relates to a kind of pedal-type scooter, particularly a kind of Kickboard Scooter that adopts human body to drive in the both legs mode of trampling.

Background technology

The Kickboard Scooter that on market, popular various employing human bodies are stood and driven in the both legs mode of trampling at present, by basic type of drive, can be divided into two large classes: a class is to adopt intermittently-driving mode, two legs drive respectively different drive mechanisms when stepping on pedal, this structure is simpler, take small volume, but driving efficiency is lower.Another kind of is traditional bicycle transmission structure, by piston crank mechanism, drives chain drum and chain drive trailing wheel, and this structure is more complicated, and possessive volume is larger, but driving efficiency is higher.

As the pedal-type scooter driving in the mode of standing, above existing these pedal-type scooters are owing to there being some shortcomings in various degree in volume, structure and type of drive, not ideal enough in addition as walking-replacing tool.As everybody knows, the mankind are through long-term natural evolution, according to human engineering, human body in operational process mainly by the realization that swings up and down away or come before and after both legs, therefore, make pedal-type scooter can reach faster running velocity and meet human engineering mode of motion, and there is less volume and simple structure, being convenient for carrying and collecting, should be the main development direction of pedal-type scooter.

Summary of the invention

The utility model provides a kind of pedal-type scooter, adopts human body in the mode of standing, the Kickboard Scooter that the mode swinging up and down before and after both legs drives, and type of drive more meets the feature of human engineering, simple and reliable for structure, can obtain running velocity faster.

In order to achieve the above object, a kind of pedal-type scooter of the utility model mainly consists of following basic structure: with the front vehicle frame of headstock, front-wheel, in the upper end of front vehicle frame, there is a rod swinging frame, a fork is respectively equipped with by bearing in both sides, front vehicle frame and rear vehicle frame can be hinged by rotating shaft, rear vehicle frame dress trailing wheel, trailing wheel employing axletree and driving crank connecting rod mechanism are coaxially arranged, by transmission, speed-changing mechanism and free-wheel clutch concentrate in trailing wheel, two pedals in left and right, one end of each pedal is connected by bearing with the rear wheel crank of homonymy, the other end is connected with the fork that is positioned at vehicle frame the same side by bearing with fork.In addition, the layout of two pedals can only separate by a metal tube makes rear vehicle frame, or metal tube is made to rear vehicle frame lower than the lowest order of pedal, and can make two Active foot plates only separate the distance of a seam, user pastes between two legs also can trample and ride when very near.

Its concrete structure has several large features: the one, and employing hind axle and piston crank mechanism coaxial configuration, concentrate on transmission, speed-changing mechanism and free-wheel clutch in trailing wheel, simple and reasonable, and do not take the external space of Kickboard Scooter.The 2nd, two of left and right Active foot plate is again the slide plate that is equivalent to Kickboard Scooter simultaneously, has simplified complete vehicle structure.The 3rd, when human body station drives Kickboard Scooter onboard, because two of left and right pedal and crank connecting link hinge portion are to move in a circle, hinged with fork is to do the hunting motion that great circle arc is similar to straight line, therefore essentially no driving dead point when pushes pedals drives Kickboard Scooter, being better than directly tramping with one's feet, moving crank connecting link moves in a circle or other unidirectional drive mode.

Pedal-type scooter of the present utility model is compared with existing similar various pedal-type scooters, has multiple advantages: 1, mode of motion is reasonable.With respect to other, adopt the exterior piston crank mechanism of pedal drive or pull chain or the type of drive of tooth bar is compared, the present invention is when foot pedal, its path of motion includes upper and lower and seesaws, quite approach human body in the path of motion of walking or running, meet the mode of motion of human engineering.2, type of drive is identical with conventional cycling mode, and the running velocity of acquisition is also identical with bicycle, and the pedal-type scooter of other different driving mode is more difficult, reaches this level.3, car load external structure is simple, almost identical with the Kickboard Scooter without drive configuration.4, because user's two legs are all to step down on Active foot plate, the center of gravity of human body is very low, can also use the larger-diameter trailing wheel center of gravity of human body when riding that also can not raise simultaneously, has higher stability and safety.

Wherein, Hinged by rotating shaft between between front vehicle frame and rear car, car load can be simply folding;

Wherein: trailing wheel employing axletree and driving crank connecting rod mechanism are coaxially arranged, in trailing wheel, speed-changing mechanism and overriding clutch are housed simultaneously;

Wherein, metal tube can be made to rear vehicle frame lower than the lowest order of pedal;

Wherein, can make two Active foot plates only separate the distance of a seam.
