Description

Folding backwards-run tricycle
Technical field:
The present invention relates to a kind of bicycle, especially a kind of can folding tricycle.
Background technology:
Two-wheeled cycle is that people are the simplest, vehicles of common, and market is extremely wide.But it is uncomfortable that two-wheeled cycle seat cushion person of low position is seated, and two-wheeled cycle also has an equilibrium problem, certain operative technique be arranged, so nearly 1/3rd crowds do not use two-wheeled cycle.
Summary of the invention:
The object of the invention provides a kind of can folding, ride comfort, easy to operate new bicycle.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it is to be the basis according to existing deck chair, other makes two front-wheel supports, two vibration damping spring supports, a pedal frame, two five cover assemblies, three axis, three central axis seats, a bicycle front fork is back vent, a direction lever, one collapsible little seat.Parallel front-wheel with two and be connected with forward foot in a step lower end, the chaise longue left and right sides by front-wheel support respectively, can rotate up and down, and load onto separately vibration damping spring with the vibration damping spring support.These two wheels the right bicycle rears, with flying as drive wheel, the left side is used for slip with front wheel.Axis all is equipped with at pedal frame two.Front axis is in one of front, and axis is in one of back, at front axis pedal and chain wheel is housed, and dress flies on the axis, puts chain.This flies the side and is welded with a dice.In addition the 3rd axis is housed in chaise longue right crus of diaphragm lower end also, is right axle, also just in time at the forward foot in a step and front-wheel support intersection.Right axle left end also is equipped with a dice, is that minor axis entangles this two dices with one section square tube.Right axle right-hand member is equipped with second chain wheel, connects with flying on another root chain and the front-wheel.The axis upper chain wheel is by flying on the axis in the chain-driving before when stepping on pedal like this, and dice makes right axle interlock by square tube on the axis, and right axle upper chain wheel is by second chain-driving front-wheel.There is central axis seat front axis and axis outside, with two steel pipes two central axis seats are welded just to consist of pedal frame.Middle central axis seat is contained in and is welded in the chaise longue forward foot in a step, in two annulus in crossbeam middle part, can rotate up and down.
In addition with one with brake wheel that rises as trailing wheel, be contained on the back vent, so-called back vent is exactly existing bicycle front fork, so change and be back vent because be contained in the back.The back vent upper end is passed one five cover assemblies and is fixed.Five cover assemblies are welded on the rear foot crossbeam, are welded with one section rocking arm on the back vent.In the chaise longue side direction lever is housed, it becomes 7 sub-shapes, at front end handgrip is housed, brake lever, and the lower end fills one section rocking arm after passing another five cover assemblies, couples together with connecting rod and back vent upper rocker arm again.These five covers are welded in chaise longue rear foot lower end and fix, and strengthen with a strut in addition.Trailing wheel can and then turn during the direction lever left-right rotation like this.Above the chaise longue rear foot, load onto a collapsible little seat.Little seat has a seat surface, a backrest.Side weld has two joint short tubes to entangle in face of present, chaise longue rear foot entablatrance, side is welded with two sections push rods and withstands cross sill, its backrest bottom also is welded with two joint short tubes and entangles the seat surface back, side is connected with two armrests, the armrest front end has dop, is stuck in the draw-in groove on the chaise longue backrest, and this is deployed condition of the present invention just.Throw off little seat two armrests, make it sagging, backrest and seat surface close up, upwards translate into perpendicular direction, catch the chaise longue seat surface on the other hand again, another hand catches backrest to close up, the front and back wheel can and then be drawn close, tangle with having contact with between the pin of front and back, pedal is upwards turned over seat surface front one hook hook again, Here it is folded state of the present invention.The people is sitting in the chair and operates, and pin is stepped on pedal, and car will advance, and hand is caught direction lever, bar left, car left-handed turning, bar be the car right-hand turning to the right.Because the wheel in two wheel back, this car front is so be the backward car.Object has a forward force of inertia owing to moving, and there are two wheels the front, is difficult for during turning overturning.So this car beneficial effect is ride comfort, and is easy to operate, traffic safety, cheap energy-conservation, environmental protection.Can work as chaise longue during parking and use, be convenient to leisure, can fold and be convenient to collection.Low-carbon economy importance is unanimously generally acknowledged in the whole world now, so add that again promotion sport and body-building market outlook of the present invention are wide, will respectively account for half of rivers and mountains with two wheel bicycles, if trailing wheel is loaded on storage battery and can becomes mini-motorcycle, better effects if with motor certainly.
