Abstract

The utility model discloses a novel overall folding structure of a foldable bicycle/foldable electric vehicle. The novel overall folding structure comprises a main pipe, a vehicle handle and a storage rack rod, wherein the main pipe is provided with two folding parts; the vehicle handle is provided with an interlocking folding structure; three shafts of the bicycle are compressed in the length direction; and a binding clock storing and binding structure is arranged below the storage rack rod. A bound (or unbound) portable foldable bicycle with a thin cuboid structure is formed by folding the bicycle with the conventional program and binding, and can be carried on a public transportation vehicle like a lengthened draw-bar box; and an electric vehicle can also be folded into a foldable electric vehicle which has a small size and is convenient to carry.

Description

The novel car load foldable structure of folding bicycle electric motor bicycle with folding

Technical field

The utility model relates to a kind of novel car load foldable structure of folding bicycle electric motor bicycle with folding, after folding, becomes the folding bicycle electric motor bicycle with folding of the less carrying convenience of volume.

Background technology

Folding bicycle and electric motor bicycle with folding on the present known market have many different-formats and kind, the utility model car load foldable structure, be on folding bicycle and the electric motor bicycle with folding kind and function on expansion.

The utility model content

In order to expand folding bicycle and electric motor bicycle with folding function, the utility model provides a kind of novel car load foldable structure, and after folding, it is less to become volume, and profile rule is neat, and the thin type cuboid of outer wrapping is arranged.Folding and expanding is quick, the folding bicycle that is easy to carry, rides, deposits, electric motor bicycle with folding.

The technical scheme that its technical matters that solves the utility model adopts is:

In car load, comprise the person in charge, handlebar, shelf bar, front and back flower-drum axle, large toothed disk axle, establish vertical direction folder and horizontal direction folder on the described person in charge; Establish the interlock foldable structure on the described handlebar.

Establish the vertical direction folder on the person in charge, make bicycle front fork forward that direction is parallel, front and back wheel axle center vertex staggers, and effectively reduces folding volume in being responsible for to; The handlebar stem end, the left and right sides of handlebar respectively has a gear to carry out the interlock foldable structure and the compressing structure of engaged transmission, thrust is added in the handlebar stem top, be not subjected to thrust on the gear, handlebar is converted into I shape and is parallel to person in charge's direction by T shape, makes folded formation form cuboid; The length dimension compression of front and back flower-drum axle, three axles of large toothed disk axle makes and wraps up body integral thickness attenuate; Wrapping cloth and shelf wrapping structure, make the external table of wrapping clean and tidy, facility is carried, is ridden, bicycle folds the back together with the wrapping function through conventional procedure, becoming a kind of portable folding bicycle with slim cuboid band wrapping (also can not wrapping up), is a kind of novel car load foldable structure, its highly versatile, the portable folding bicycle of wheel diameter can be common to, the portable folding battery-driven car can be common to equally from 8 inches to 24 inches scopes.

The utility model beneficial effect

Bicycle is after folding, and volume is less, becomes a kind of portable folding bicycle with thin type cuboid band wrapping (also can not wrapping up), as the trolley luggage of lengthening, can carry to take advantage of and change mass transportation facilities; It is less that battery-driven car also can be folded into volume, and the electric motor bicycle with folding that facility is carried is realized on folding bicycle, the electric motor bicycle with folding kind and the expansion on the function.

Among Fig. 1 Fig. 2 Fig. 3,1. be responsible for 2.3. folder, 4. handlebar, 5.7.8. shelf bar fabricate block, 6. wrapping cloth, 9. Brake lever, 10. handlebar stem, 11. front-wheels, 12. trailing wheels, 13. shelf, 14. flywheels, 15. around all wrapping cloths, 16. saddles, 17. pedal rods, 18. large toothed disks, 19. standpipes.

The specific embodiment

In Fig. 1, shelf when shelf bar 5.7.8. is expansion, wrapping cloth 6 is deposited thereunder.Be responsible on 1 and establish vertical direction folder 2, horizontal direction folding device 3, handlebar is established interlock foldable structure 4.

In Fig. 2, when shelf bar 5 turns to I by H, make wrapping cloth stretching, can carry out around folded formation one week wrapping, when the first shelf bar 8. during at the J place, on the second shelf bar 7. handle is arranged, the wrapping body can be walked (trailing wheel rolling) in tow, when the first shelf bar 8. during in the k position, the second shelf bar 7 can carried the wrapping body walk.

Shown in Figure 4, folder 2, when first tommy bar 20 is in tension, be responsible for front end 21 at the P place, be the bicycle expanded position this moment, when first tommy bar 20 is in releasing orientation, is responsible for front end 21 and turns to the Q place by the P place, bicycle front fork is forwarded to be responsible for direction parallel, finish the vertical folding action.

Shown in Figure 5, when folder 3. is in tension when second tommy bar 22, being responsible for I is the bicycle expanded position at the V place this moment, when second tommy bar 22 is in releasing orientation, be responsible for 1 and turn to the W place by the V place, bicycle wheels axle center vertex is staggered, attenuate folded formation thickness, finish horizontal folding action.

Among Fig. 6 Fig. 7 Fig. 8,23 eccentric tommy bars, 24 handlebar stems, 25 clamping sleeves, 26 gears, 27 springs, 28 pipes.

Shown in Fig. 6 Fig. 7, pull loose eccentric rod 23, clamping sleeve 25, upspring by action of the spring, at this moment handlebar stem 24 becomes flexible and turns to the X places, and gear transmission other end handlebar stem 24 ' turns to X ' to locate simultaneously, realize that left and right sides handlebar stem interlock is folding, otherwise action is for launching rideable state, and thrust is added in the handlebar stem top, and gear is not subjected to thrust.

As shown in figure 10: AL L=120～140 new structures get 120
