Description
(1) technical field:
The present invention relates to vehicle, particularly a kind of two take turns or three-wheel upset or fold concertina-wise car.
(2) background technology:
Existing two take turns or the three-wheel folding car is mainly the folding of vehicle frame, the vehicle frame that connects front-wheel and trailing wheel is divided into front vehicle frame and back vehicle frame, forward and backward vehicle frame is provided with side to be changeed the joint or lifts the joint, but the superimposition of forward and backward vehicle frame side lifts by folded, folding car structure after the side superimposition lifts is at random not to become the car sample, lateral thickness increases, or highly increases, and inconvenience is deposited and guided and supported.
(3) summary of the invention:
At the weak point of original folded bicycle, the purpose of this invention is to provide littler, the upset or the fold concertina-wise car of depositing, guiding and supporting and carrying out of being more convenient for of a kind of folding back longitudinal size.
Can realize the upset or the fold concertina-wise car of above-mentioned purpose, comprise the forward and backward vehicle frame that connects forward and backward wheel, described front vehicle frame is by the turning cylinder of the front fork connection front vehicle wheel of barre, and different is:
1, described folded bicycle is convertible.Be that described forward and backward vehicle frame is horizontal forward and backward framework, rear frame is to after-opening, connect by the rotary joint that can lock between the described forward and backward framework, the axis parallel of described rotary joint is in the turning cylinder of forward and backward wheel, the width of described forward and backward framework is greater than the rear wheel width, front baffle length is greater than the rear wheel diameter, and the connection mode of described rear frame and rear wheel is that the back vent of rear frame and the turning cylinder of rear wheel are hinged.
When upset is folding, remove locking, back vehicle frame is turned over, front vehicle frame upwards lift backward and after vehicle frame overlapping in the rear wheel place, front and rear wheel draw close mutually finish folding; Counteragent then is the expansion of folded bicycle.
2, described folded bicycle is telescopic.Be that described forward and backward vehicle frame is the horizontal forward and backward framework of level, the corresponding frame pipe between the described forward and backward framework adopts the flexible insertion that can lock to connect.
Folding when flexible, remove locking, insert between the forward and backward framework and shorten, front and rear wheel draw close mutually finish folding; Counteragent then is the expansion of folded bicycle.
In upset or the fold concertina-wise structure, described forward and backward wheel is single-wheel, and the identical or front vehicle wheel diameter of forward and backward wheel diameter is less than rear wheel, and forward and backward wheel is the shortest folding position when colliding.
Described front vehicle wheel has side changes the structure parallel with rear wheel, in the shortest above-mentioned folded position, changes by the side of front vehicle wheel, can further shorten the folding position.
The another kind of mode that shortens the folding position is that described forward and backward wheel is respectively two-wheel and single-wheel, described two-wheel is positioned at the single-wheel both sides, and the identical or front vehicle wheel diameter of described forward and backward wheel diameter is less than rear wheel, when folding, two front vehicle wheels and rear wheel can be overlapped, and reach the shortest folding position.
The vehicle seat of folded bicycle is supported by the seat bar, and the seat bar is plugged in the bar cover and can locks, and in convertible foldable structure, described seat bar cover is installed on front vehicle frame or the back vehicle frame.
The back seat rotation lock of folded bicycle is on the seat bar, and back seat turns to the rear wheel top forward when folding.
When folded bicycle is when comprising the battery-driven car that drives battery, described driving battery is installed on back seat or the barre.
When folded bicycle is when comprising the manpower of chain drive or motor-driven upset folded bicycle, chain drum in the described chain drive is installed on the front vehicle frame, the chain drooping section of described chain drive is supported by the tension wheel that is installed on the front vehicle frame, and chain is not loose when making the vehicle frame upset.
Installation activity stretcher on the described front vehicle frame.
For realizing compacter foldable structure, described barre is that its rotary joint is higher than rear wheel to the folding body of rod of rear wheel, and barre is folded in the rear wheel top behind the vehicle frame folding; Install on the described barre to the folding handle of the body of rod.
Advantage of the present invention:
1, upset of the present invention or fold concertina-wise car have proposed a kind of brand new folding mode, and the tricycle structure that is designed to is more reasonable, the vehicle collapsed compact, and volume is minimum and can stablize implementation, is that traditional folded bicycle is incomparable.
2, the present invention is simple in structure, and is folding very light and handy, quick and easy with expansion process, is easy to carry, and makes car with the people extremely, on very close terms.
