Abstract

The invention discloses a foldable bicycle. The foldable bicycle is formed by the combination of a front end and a rear end, wherein the front end consists of a bicycle main rack and main accessories assembled on the bicycle main rack; the bicycle main rack mainly comprises a main beam tube, a head tube, a middle tube, a rotating base and a combining device; the main accessories, namely a foldable handlebar, a front fork and a front wheel, are assembled on the head tube; a seat cushion is assembled on the middle tube through a seat bar; the rear end consists of a rear fork, and main accessories, namely a chain wheel, a chain and a rear wheel, which are assembled on the rear fork; the rotating base is arranged under the main beam tube, in the direction from the middle tube to the head tube; the rear fork is hinged to the rotating base; a connecting device through which the rear fork and the bicycle main rack can be mutually combined or separated is arranged between the rear fork and the bicycle main rack; one end of the connecting device is connected with the rear fork, and the other end of the connecting device is connected with the combining device on the bicycle main rack; an angle is designed on the central plane of the rotating base and the bicycle main rack, thereby allowing the rear wheel and the front wheel to be staggered to obtain a small folded size after the rear fork is rotated around the rotating base and folded.

Description

A kind of foldable bicycle

Technical field

The present invention relates to bicycle art, be related specifically to foldable bicycle.

Background technology

Existing Folding Bicycle, majority has come by arranging folded box at vehicle frame main beam pipe, the folding axle center of folded box is perpendicular to the ground, in folding, open the latching device of folded box, by the folding axis rotation of the trailing wheel of folded bicycle around folded box, trailing wheel and front-wheel folding to be drawn close to parallel, and collapsible tap is also rolled over to front-wheel pastes box to complete folding, reach volume-diminished, tidy up order easily.The folding mode of this folding bicycle, vehicle frame main beam pipe must be cut off, then a folded box is added to reach folding function, the shortcoming of this mode roughly has: 1, vehicle frame main beam pipe is cut off the folded box adding other shape, and the overall aesthetic of such vehicle frame main beam pipe has been destroyed; 2, originally complete vehicle frame main beam pipe is cut off, and increases and has welded complicated folded box, certainly will have sacrifice like this, add more how uncertain hazard index to riding of bicyclist in intensity and rigidity; 3, when operation is folding, heavier trailing wheel is allowed to remove tight front-wheel around folded box axis rotation, this needs to be overcome heavier trailing wheel weight removed this folding process by the larger strength of paying of people, and the people more weak to some healths brings inconvenience (as women, child etc.) when operating folding.

Summary of the invention

The technical matters solved:

Be the deficiency for existing Folding Bicycle, designing a kind ofly does not need to weld on main-beam pipe that namely folded box does not destroy folding bicycle frame main-beam pipe, folding procedure is lighter, more convenient, outward appearance is more beautiful, more comfortable foldable bicycle of riding order of the present invention.

The technical scheme of technical solution problem:

A kind of foldable bicycle, combined by front-end and back-end: front end is made up of car owner's frame and the key fitment be assemblied on car owner's frame again, car owner's frame mainly comprises main-beam pipe, head tube, middle pipe, rotation seat and combining device, key fitment folding handlebar, front fork, front-wheel are assemblied in head tube place, and seat cushion is assemblied in middle pipe place by seat bar; Rear end is made up of back vent and key fitment fluted disc, chain and the trailing wheel be assemblied on back vent, below main-beam pipe, middle pipe is provided with rotation seat toward head tube direction, back vent is hinged with by rotation seat, the connecting device that it can be made to be combined with each other or separate is provided with between back vent with car owner's frame, one end of connecting device is connected with back vent, and one end is connected with the combining device on car owner's frame in addition; The centre plane of rotation seat and car owner's frame be also designed with can make back vent rotate around it folding after trailing wheel and front-wheel mutually stagger to reach the angle of less folding volume.Time folding, bayonet lock on operation combining device, make to manage in back vent and vehicle frame to separate, now seat cushion place is up carried, whole back vent drives trailing wheel and fluted disc, chain etc. will rotate around rotation seat and is folded to trailing wheel and front-wheel is adjacent to, is more down folded to by folding handlebar to be adjacent to front-wheel and to be passed in vehicle frame by seat bar and manages the folding process down having inserted Folding Bicycle.

When opening, seat bar be retracted to appropriate location and fix, back vent rotated backward and the combining device at pipe place in vehicle frame of the connecting device on it is combined, then folding handlebar being expanded to riding condition to complete the expansion of Folding Bicycle.

To be combined with connecting device by combining device in order to fast speed or to separate, connecting device is provided with a positioning rod, also be provided with an elastic component, radius stay one end is "T"-shaped, the other end is fixed on back vent together with elastic component, "T"-shaped end through combining device base, the bayonet lock allowing radius stay block when combining device being designed with protrusion, radius stay can be made again to throw off when retracting, elastic component can also play the effect reducing vibrations in ride, makes to ride more comfortable.

In order to satisfied different bicyclist is to the requirement of riding, combining device is also designed with bayonet lock with the use of time radius stay can be stoped to move to make back vent become rigidly connected locating dowel pin with being connected from elasticity between car owner's frame, become after being rigidly connected, elastic component is by inoperative, and Folding Bicycle will lose shock-absorbing function.

In order to by folding for Folding Bicycle rear more convenient movement, be provided with hook seat at main-beam pipe place, on back vent, be provided with stay hook simultaneously, after folding, stay hook will hook the hook seat on main-beam pipe, such back vent and assemble superincumbent accessory and would not arbitrarily throw off, with facilitate folding after movement.

According to different technological requirements or hobby, connecting device can also have elastomeric firm plate by one or more and associated fixture forms.

Beneficial effect:

The main-beam pipe of Folding Bicycle is not cut off to weld the folded box for folding, and the intensity of such main-beam pipe can not be destroyed, and overall aesthetic is better simultaneously; This kind of folding mode is that longitudinal rotating folds in addition, all can come by Folding Bicycle self gravitation when folding or launch operation, more laborsaving like this, more convenient; Increase springing between back vent and car owner's frame after, riding is the part vibrations can filtering uneven road surface, more can increase comfort level of riding.
