Abstract

The utility model relates to a folding multifunction bicycle, mainly composed of a discrete front bicycle body, a discrete back bicycle body, a cross beam and an oblique beam. The cross beam and the oblique beam can rotate around a cross shaft. The bicycle bodies are provided with a front goods shelf and a back goods shelf, and the back bicycle body is provided with symmetrical small wheels. The cross beam of the bicycle and a vertical upright of a saddle form a two-stage folding structure. The bicycle can be quickly and smartly folded into a baggage car and can transport the goods when people go upstairs or down stairs. The folding bicycle has the advantages of reasonable and reliable structure, convenience, practicality and portability. The folding bicycle is an ideal tool for riding and carrying goods in households and traveling.

Description

Multifunctional foldable bicycle

The utility model relates to a kind of folding multi-functional bicycle.

Present various bicycle style is more, but mostly big, the Collapsible bicycle of form fixed volume or function singleness or complex structure, moulding is not attractive in appearance, poor practicability.

The purpose of this utility model be to provide a kind of simple and reliable for structure, collapsible, variation is flexible, multi-functional, volume after folding is little, the formula multifunction bicycle is folded in portative demolition, for travelling at home provides a kind of comparatively desirable walking-replacing tool.

The utility model comprises: front vehicle body, aftercarriage, overarm brace, cant beam, steamboat, steamboat colligator are formed.Specifically front vehicle body is by front vehicle wheel, preceding shelf, front fork, preceding pivoted frame, handle riser and handlebar are formed, and aftercarriage is by vehicle seat, the vehicle seat core bar, vertical rod, rear wheel support, back shelf, rear wheel, steamboat, steamboat colligator and by pedal, axis, the power drive that sprocket wheel constitutes is formed, and front vehicle body assembles into bicycle with cant beam by movable axis by overarm brace with aftercarriage.Above-mentioned overarm brace is the two sectional type structure, and middle by the movable axis connection, overarm brace can be folding around movable axis.The structure of vertical rod is also identical with overarm brace to be constituted by folding two sections, and junction is added with movable axis.Symmetrical steamboat in the bicycle is the position that is installed in the back axle both sides by the steamboat colligator, and this colligator is the adapter plate of a band connecting rod, and the connecting rod other end is equipped with steamboat, and adapter plate is fixed on the back axle position of rear wheel support.In addition, for increasing the intensity of bicycle, be with lock collar two sections overarm brace junctions, it is a sleeve pipe that is enclosed within on the crossbeam, and when being positioned at the movable axis position, two sections overarm braces can not fold.In the structure of the present utility model except that folding position be connect with movable axis, and overarm brace is rolled over downwards, axis is partly upwards rolled over, outside the vertical rod part is rolled over backward, other parts such as front vehicle body, aftercarriage and motivation transfer motion part all can design by common bicycle structure and assemble.When the lock collar of drawing back on the overarm brace, just can as shown in Figure 2, fall handlebar and vehicle seat again by the above-mentioned vehicle frame that has folded bicycle, bicycle just is minimum folding volume shape.

The utility model is owing to adopted suitable being connected of novel annex flexibly.Promptly guarantee the reliable intensity that bicycle has, can realize the folding of multiduty variation and minimum volume again.So the utlity model has higher utility, be easy to apply.

Accompanying drawing is a constructional drawing of the present utility model:

Fig. 1 is the general assembly sketch of the utility model multifunctional foldable bicycle;

Fig. 2 is a kind of invagination scheme drawing of Fig. 1.

Among the figure: 1. front vehicle wheel; 2. preceding shelf; 3. preceding pivoted frame; 4. front rotary shaft; 5. handle riser; 6. handlebar; 7,9,11,15,23,26. movable axis; 8,10. overarm brace; 12. vehicle seat; 13. vehicle seat core bar; 14. vertical rod; 16. back shelf; 17. rear wheel; 18. steamboat; 19. steamboat colligator; 20. rear wheel support; 21. pedal; 22. axis; 24. sprocket wheel; 25. cant beam; 27. front fork.

The utility model is to realize like this according to the project organization of figure (1): by front vehicle wheel (1), and preceding shelf (2), front fork (27), preceding pivoted frame (3), handle riser (5) and handlebar (6) are formed front vehicle body, vehicle seat (12), vehicle seat core bar (13), vertical rod (14), back shelf (16), rear wheel (17), steamboat (18), steamboat colligator (19), pedal (21), axis (22), sprocket wheel (24) is formed aftercarriage.Wherein stem (5) is set in the front fork (27), and standpipe (5) can move up and down or rotate in (27), and can lock in desired location, and the combination of these parts is identical with the structure of ordinary bicycle and installation process.Pedal (21), axis (22), sprocket wheel (24) and rear wheel (17) also can be assembled into bicycle driving partial sum aftercarriage by the structure and the installation process of ordinary bicycle.Between front vehicle body and the aftercarriage with two sections overarm braces (8) and (10) and cant beam (25) by movable axis (7) and (26) on the preceding pivoted frame (3), movable axis (11) in the vertical rod (14) and (15) fit together the formation bicycle with the movable axis (23) of rear wheel support (20) front end, symmetrical steamboat (18) in the aftercarriage is installed in the back axle position of bracket of back axle both sides by steamboat colligator (19), and symmetrical steamboat (18) can rotate up and down around back axle with car body.Install by the method for ordinary bicycle as shelf (2) before the annex of bicycle and back shelf (16), but back shelf (16) are folding in each junction.

Fig. 2 is the structural form scheme drawing after the utility model folds.For clear, only provide the position of each movable axis and the shape of each chief component of folding back among the figure.Folding process is to push the lock collar that is enclosed between overarm brace (8) and (10) aside particularly, mention axis, crossbeam (8) and (10) are folding downwards, cant beam (25) and rear wheel support (20) be folding upwards, vertical rod (14) is folding outwards, and symmetrical steamboat (18) turns to the middle two positions of front and back wheel with car body in trailing wheel.

In sum, the utility model makes up by dress easily by various novelties and general-duty parts, can realize bicycle, baggage car, the multiple function of purchase.Be people house, travel, manned loading, instrument easy to carry.
