Technical field
The utility model is related to bicycles, and in particular to a kind of folding bicycle.
Background technology
Folding bicycle carries, easy to use, production technology comparative maturity.At present folding bicycle be all to miniaturization and
Lightweight direction is developed, and but ignores the comfort ridden.Mostly using two wheel constructions, stop needs to use existing folding bicycle
Foot or stent support can just come to a complete stop.Mode of riding is sitting formula, and back does not have supporter, fatiguability of riding for a long time.
Invention content
Technical problem to be solved in the utility model is：In view of the above-mentioned problems, providing one kind sets backed Three-wheel type
Folding bicycle.
The technical solution of the utility model is：Folding bicycle, including vehicle frame, front fork, back vent, handlebar, vehicle seat, preceding
Wheel, trailing wheel and sprocket wheel, front wheels and rear wheels are fixed on the front and back ends of vehicle frame by front fork and back vent respectively, and handlebar is fixed on front fork
Top, the vehicle frame are made of front fork casing, upper beam and underbeam, and upper beam and underbeam are formed by two sections be hinged, vehicle seat
Upper beam back segment is fixed on, upper beam rear end is hinged with backrest, upper beam and underbeam in vehicle seat rear and is hinged on front fork respectively at its front end
The upper and lower part at casing rear, is detachably connected with damper between upper beam and underbeam, front fork by front fork casing rotationally
It is fixed in front of vehicle frame, back vent is fixed on underbeam rear end, is equipped with flywheel at front-wheel wheel shaft, sprocket wheel is fixed on by forked stent
Front-wheel front upper place simultaneously passes through chain and is connect with flywheel.
The utility model has the technical effect that：It has it is reasonable in design, small, light-weight, be convenient for carrying and make
With and ride the advantages of comfortable, the structure design to be landed using three-wheel can stop stabilization without supporter, and backrest both may be used
By rest, and power can be borrowed when riding.

Specific embodiment
As shown in Figures 1 to 4, folding bicycle, including vehicle frame 1, front fork 2, back vent 3, handlebar 4, vehicle seat 5, front-wheel 6, trailing wheel 7
With sprocket wheel 8, front-wheel 6 and trailing wheel 7 are fixed on the front and back ends of vehicle frame 1 by front fork 2 and back vent 3 respectively, and handlebar 4 passes through on front fork 2
The upright bar at end is fixed on 2 top of front fork, and the vehicle frame 1 is made of front fork casing 9, upper beam 10 and underbeam 11, upper beam 10 and underbeam
11 are formed by two sections be hinged, and vehicle seat 5 is fixed on 10 back segment of upper beam, and 10 rear end of upper beam is hinged in 5 rear of vehicle seat and leans on
The back of the body 12, upper beam 10 and underbeam 11 are hinged on the upper and lower part at 9 rear of front fork casing respectively at its front end, upper beam 10 and underbeam 11 it
Between be detachably connected with damper 13, front fork 2 can be fixed on to left-right rotation 1 front of vehicle frame, back vent 3 by front fork casing 9
11 rear end of underbeam is fixed on, is equipped with flywheel at 6 wheel shaft of front-wheel, sprocket wheel 8 is fixed on 6 front upper place of front-wheel simultaneously by forked stent 14
Realization transmission is connect with flywheel by chain.
The back segment of the underbeam 11 is forked, and the trailing wheel 7 is two, is fixed on underbeam 11 by a back vent 3 respectively
The end of two bifurcateds of back segment makes front-wheel 6 and two trailing wheels 7 form the support construction of triangle.
Between the leading portion and back segment of the underbeam 11 be equipped with changeover portion 15,15 both ends of changeover portion respectively with after the leading portion of underbeam 11
End and back segment front end are hinged.Damper 13 is fixed on the back segment of upper beam 10 and the changeover portion 15 of underbeam 11.Changeover portion 15
It can be integrated with leading portion, the shape of bending be made, in favor of vehicle frame folding.
The handlebar 4 is made of interlude 16 and handle section 17, and handle section 17 is hinged on the both ends of interlude 16.
Articulated section is equipped at the prong of the lower end of the front fork 2, stent 14 is hinged on the articulated section.
The upright bar of the handlebar 4 and 2 upper end of front fork is by articulated connection, so as to can be with upper beam 10 1 when car body folds
Play folded deformation.Or upright bar is formed by two sections be hinged, handlebar 4 is fixed on the epimere of upright bar.Handlebar 4 can also be with upright bar
It is fixedly connected, but the junction of its upright bar need to be designed to the shape being bent forwards, interferes to avoid with the upper beam 10 after folding.
Handlebar 4 highly can be suitable with vehicle seat 5, and when riding, 4 top of handlebar is lifted in leg, and human body back leans against backrest 12
On, power can be borrowed when stepping on tap pedal drive sprocket.
