At present, the folding electric bicycle structure is numerous, for the function that realizes folding, basically all be the improvement of body frame structure for automotive, the patent of invention of a kind of " Folding Bicycle " by name is disclosed as Chinese patent ZL 87106328, publication number 87106328, open day, 1988.04.27, a kind of Folding Bicycle, the crossbeam of pillar and at least one connection front and back post before and after having, purpose provides a kind of bicycle, and in seconds the autograph letter one action is several just can fold up car down compactly, and car body was fastening when bicycle was in normal operating condition, very dexterous when being in folded state, only folding to a direction.The crossbeam of car body is divided into two parts, and the mutual movable joint of two parts of crossbeam connects, and is connected with the front and back pillar, when two parts of crossbeam are in folded state respectively towards back prop.But also there is shortcoming still compact inadequately behind the whole vehicle frame folding in this design.
Summary of the invention
The purpose of this utility model has provided the compact Folding Bicycle in a kind of folding back.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of Folding Bicycle, comprise front-wheel, trailing wheel, handlebar, seat cushion and vehicle frame, described vehicle frame comprises front fork stem, rear fork, seat cushion pole, last cross support arm, following cross support arm, front tension bar and back stay
The left end of last cross support arm and following cross support arm is articulated in A point and B point with front fork stem respectively;
The right-hand member of last cross support arm and following cross support arm is articulated in D point and C point with seat cushion pole respectively;
The lower end of front tension bar and last cross support arm are articulated in the E point;
The lower end of back stay and rear fork are articulated in the H point;
The upper end of front tension bar and the upper end of back stay are articulated in F point and G point with slide block respectively, slide on the present advance expenditure bar of described slide block set, are provided with positioning and locking device on slide block;
The lower end of seat cushion pole and the front end of rear fork are articulated in the I point.
As preferably, the left end of last cross support arm and following cross support arm is articulated in A point and B point with preceding articulated slab respectively, and preceding articulated slab is fixed on front fork stem; The right-hand member of last cross support arm and following cross support arm is articulated in D point and C point with the back articulated slab respectively, and back articulated slab is fixed on the seat cushion pole.
As preferably, latching device comprises locating dowel pin and is arranged on knock hole on the seat cushion pole relevant position.
As preferably, back stay be associated with damping spring after be articulated in the H point with rear fork again.
As preferably, the rear fork front end also is fixed with a strut bar.
Therefore, the utlity model has the compact characteristics in folding back.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is a structure principle chart of the present utility model.
The specific embodiment
Below by embodiment, and, the technical solution of the utility model is described in further detail in conjunction with the accompanying drawings 1 to accompanying drawing 2.
Embodiment, referring to accompanying drawing 1 to accompanying drawing 2, a kind of Folding Bicycle, comprise front-wheel 1, trailing wheel 12, handlebar 3, seat cushion 8 and vehicle frame, described vehicle frame comprises front fork stem 2, rear fork 14, seat cushion pole 7, last cross support arm 4, following cross support arm 16, front tension bar 5 and back stay 10
The left end of last cross support arm 4 and following cross support arm 16 is articulated in A point and B point with preceding articulated slab 21 respectively, and preceding articulated slab 21 is fixed on front fork stem 2; The right-hand member of last cross support arm 4 and following cross support arm 16 is articulated in D point and C point with back articulated slab 22 respectively, and back articulated slab 22 is fixed on the seat cushion pole 7.
The lower end of front tension bar 5 and last cross support arm 4 are articulated in the E point;
The lower end of back stay 10 and rear fork 14 are articulated in the H point;
The upper end of the upper end of front tension bar 5 and back stay 10 is articulated in F point and G point with slide block 6 respectively, described slide block 6 is enclosed within on the seat cushion pole 7 and slides, be provided with positioning and locking device 9 on slide block 6, described latching device 9 comprises locating dowel pin and the knock hole that is arranged on seat cushion pole 7 relevant positions;
The front end of the lower end of seat cushion pole 7 and rear fork 14 is articulated in the I point;
Rear fork 14 front ends also are fixed with a strut bar 15.
When needs used by bike, the locating dowel pin of the latching device 9 on the slide block 6 just was inserted in the knock hole, in order to the position of fixing slide block 6 present advance expenditure bars 7, made and can carry the people by the fixing of whole vehicle frame.
But when needing to fold, unplug locating dowel pin, slide block 6 slides from the bottom up along seat cushion pole 7, thereby drive front tension bar 5 and back stay 10 pullings upward cross support arm 4 and rear fork 14, form a folding structure, in folding process, because front-wheel has folded to seat cushion pole 7 directions and has drawn close, so increase a strut bar 15, by strut bar 15, trailing wheel 12 with support 13 and form a gusseted, prevent that the flywheel in the folding process from contacting with ground with chain.
