Description

A kind of Hand drived scooter

Technical field

The present invention relates to a kind of scooter, more particularly to a kind of Hand drived scooter.

Background technology

Scooter is improved a kind of emerging sports products on the basis of conventional skateboard, because its speed is moderate, manipulation It is easy to learn, be difficult to fall down and welcome by each age group people, especially teenager and children, have become a kind of prevalence City walking-replacing tool and body-building recreation product, scooter in the market mainly has two kinds of type of drive：One kind is electronic Scooter, but Segway Human Transporter complex structure, volume and weight it is larger, and need Jing often to charge, it has not been convenient to carry and use；It is another Plant and driven for manpower pedal, drive scooter to advance by single the feet step on the ground, but the leg that pedal process declines on pedal needs frequently Numerous to go down on one's knees, most of weight of body can fall on the knee of bending, and to knee larger pressure is caused, and another one leg is needed Stretch and pedal ground, easily cause crotch's muscular fatigue, there is the hidden danger of knee and muscle tissue damage of crotch, in addition, when pedaling ground If overexerted, handlebar double swerve can be made, cause scooter direction unstable, to scooter driving safety unfavorable shadow is caused Ring.

The Chinese patent of Patent No. 012094994 discloses a kind of Hand drived scooter, and it is in the pivot of the rear end of a pedal Socket part wears a wheel shaft, the trailing wheel that is pivoted with the wheel shaft, and on also fixed two sprocket wheels on the wheel shaft, and two sprocket wheel one is respectively arranged Chain, its each chain one end respectively connects and sets a spring, and the other end of spring is fixed on pedal bottom；It is connected with the front end of pedal One wheel seat, the wheel seat is provided with front-wheel axle steer interlinked mechanism, and nationality is connected with a front axle by the foresteerage gear, with before this Wheel shaft two ends are respectively pivoted a front-wheel, and are respectively provided with a positioning seat in the front end both sides of pedal, and its each positioning seat is respectively pivoted one Rocker shaft, and in the fixed swivel of rocking bar axle portion, above-mentioned chain another end extends and is fixedly arranged on the swivel eccentric part.The hand cunning Wooden handcart is realized driving by two groups of chains and sprocket wheel, realizes turning to by body inclination, but complex structure, and parts are excessive, whole Body is oversized, turns to dumb.

The content of the invention

According to above the deficiencies in the prior art, the technical problem to be solved is：A kind of Hand drived scooter is provided, Advance, its simple structure can be driven by arm-shaking, it is easy to which manipulation is used, and smooth ride can mitigate the motion of leg Burden.

The present invention is realized by following technical scheme：A kind of Hand drived scooter, including vehicle body, on vehicle body Front wheels and rear wheels, front-wheel crotch be fixedly mounted on body structure head tube be set with couple, front-wheel crotch by rotating shaft hinge Rocking bar is connect, handlebar cross bar is fixed in the upper end of rocking bar, and driving gear, driving gear and the wheel shaft for supporting front-wheel are fixed in the lower end of rocking bar On driven gear be meshed.

Preferably, described rocking bar includes montant, and montant lower end is installed with bow II, under the side of support II End is provided with driving gear；Described front-wheel crotch includes being set with the central siphon for coordinating with head tube, and central siphon lower end is installed with " H " shape support I, support I lower ends are hinged with wheel shaft, and support I upper ends are hinged with support II both sides by rotating shaft.

Preferably, described front-wheel crotch includes being set with the central siphon for coordinating with head tube, and central siphon upper end is installed with company Frame is connect, central siphon lower end is installed with Y-shaped support III, and support III lower ends are hinged with wheel shaft；Described rocking bar includes perpendicular Bar, montant lower end is provided with driving gear, and montant is hinged by rotating shaft with link.

Preferably, also including the stop for limiting rocking bar pendulum angle.

Preferably, described stop include be arranged on support II sides arc-shaped slot and be matched therewith, arrange Limited block on support I.

Preferably, described stop include be fixedly mounted on central siphon upper end, upwards bending tilt two before and after support II The catch of side.

Preferably, described stop includes being enclosed within montant the spacing ring being connected with support III.

Preferably, also including the flywheel for being sleeved on restriction front-drive direction on wheel shaft.

Preferably, described flywheel inner ring suit is fixed on wheel shaft, and outer ring is fixed in the wheel hub of front-wheel.

Preferably, described flywheel inner ring suit is fixed on wheel shaft, and outer ring is fixed in driven gear.

Preferably, the handle rotated relative to handlebar cross bar is set with described handlebar cross bar.

Preferably, described body tail is provided with braking vane.

The invention has the beneficial effects as follows：

This Hand drived scooter both can drive advance in which pedal by foot-operated, can drive advance by arm-shaking again, can be with Leg and the upper limbs force of user are tempered, the motion burden of user's knee and crotch is reduced, while driving structure of the present invention Advantages of simple, parts are few, and scooter overall dimensions and weight are little, are convenient for carrying and use；

By driven by shaking, body both sides have an effect identical, can avoid the situation of scooter double swerve, increase scooter Cruising characteristic and security；

Driving and steering can simultaneously be completed by operation handlebar cross bar and rocking bar, and drive mechanism and steering mechanism are combined into one Body, it is not necessary to other body parts or action completing, turn to it is flexible, it is simple to operate, enhance the maneuverability of scooter；

The arm of force between handlebar cross bar and pin joint is more than between driving gear and driven gear meshing point and pin joint The arm of force, forms leverage, and user just can form larger driving force by less strength, saves strength and is easier to manipulate Use.
