Description

35 centimetres of portable folding bicycles

Technical field

The utility model relates to a kind of later-model method for folding, after folding, and the folding bicycle of the less carrying convenience of volume.

Background technology

Folding bicycle on the present known market has many different-formats and kind, 35 centimetres of portable bicycles of the utility model, be on the folding bicycle kind and function on expansion.

The utility model content

In order to expand the folding bicycle function, the utility model provides a kind of wheel diameter 35 centimetres of portable bicycles, 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.

The new solution technical scheme that its technical matters adopted of this practicality is:

A kind of wheel diameter portable folding bicycle has two bursts on it is responsible for: the interlock of handlebar two ends is folding; The compression of three shaft lengths; Shelf are established wrapping cloth and are deposited a kind of new type foldable method with folding device, can be folded into the less profile of volume neatly has wrapping (also can not wrapping up) book shape cuboid than rule portable folding bicycle by this jackknife method.

A kind of new type foldable method, be folded into the portable folding bicycle of the neat less book shape of the volume cuboid of rule of profile, same being suitable for: 25 centimetres of (10 inches), 30 centimetres (12 inches) of wheel diameter, 40 centimetres (16 inches), 45 centimetres (18 inches), 50 centimetres (20 inches), 55 centimetres (22 inches), 60 centimetres (24 inches) eight specification bicycles, form serial portable folding bicycle.Be equally applicable to make the portable folding electric moving aid vehicle.

In car load, comprise the person in charge, handlebar, shelf bar, establish vertical direction foldable structure and horizontal direction foldable structure on the described person in charge; Establish the interlock foldable structure on the described handlebar; The shelf bar is transferred and is provided with wrapping cloth.

Front and back wheel flower-drum axle, the large toothed disk axis compresses on the length dimension of these three axles; Shelf establish that wrapping cloth is deposited and folding device, carry out the folding back of bicycle conventional procedure together with the wrapping function, become a kind of portable folding bicycle with the wrapping of thin type cuboid band, are a kind of new type foldable methods.

The beneficial effects of the utility model are: bicycle is after folding, oad: about 0.68 * 0.38 * 0.18 meter of length, long-pending about 0.05 cubic meter of three, the three and about 1.25 meters thin type cuboid, as the little shape trolley luggage of lengthening, can carry to take advantage of and change mass transportation facilities, realize on the folding bicycle kind and the expansion on the function.

Principal parameter among Fig. 1 Fig. 2:

A. wheel diameter 350, b. the two-wheeled width between centers 1000, c. in the large toothed disk with trailing wheel width between centers 370, it is high by 300 that d. large toothed disk center is liftoff, it is high by 1100 that the e handlebar is liftoff, f. the handlebar lifting is apart from 200, g. saddle is liftoff high by 1000, h. saddle lifting distance 250, i. folded formation length about 680, j. the folded formation width is about 380, k. folded formation height about 180.

Among Fig. 1 Fig. 2,1. be responsible for, 2.4.5. shelf bar fabricate block, 3. wrapping cloth, 6. Brake lever, 7. handlebar, 8. front-wheel, 9. trailing wheel, 10. shelf, 11. flywheels, 12. around all wrapping cloths, 13. saddles, 14. pedal rods, 15. large toothed disks, 16. standpipes.

The specific embodiment

In Fig. 1, shelf bar the 2,4, the 5th, shelf when launching, wrapping cloth 3 is deposited thereunder.Be responsible on 1 and establish vertical direction foldable structure A, horizontal direction foldable structure B; Interlock foldable structure C is established at the handlebar two ends.

In Fig. 2, when shelf bar 2 turns to the I place by the H position, make wrapping cloth 3 stretching carrying out around folded formation one week wrapping, when the first shelf bar 5 during at the J place, on the second shelf bar 4 handle is arranged, the wrapping body can be walked (trailing wheel rollings) in tow, when the first shelf bar 5 during in the k position the second shelf bar 4 make the delivery of cargo handles and the wrapping body can carried, the wrapping physical efficiency is erect placement.

As shown in Figure 4, first tommy bar 17 is at the M place, first tie rod 19 is at the O place, this is the tension that is in when launching, when turning to the L place, first tommy bar 17 drives eccentric shaft 18 backward rotation, unclamp first tie rod 19 and turn to the N place to stop by the O place, at this moment hinge can rotate, and makes the person in charge's 1 front end 21 turn to the Q place to finish the vertical folding action by the P place.

As shown in Figure 5, second tommy bar 22 is at the S place, second tie rod 25 is at the u place, this is the tension that is in when launching, when turning to the R place, second tommy bar 22 drives eccentric shaft 24 backward rotation, unclamp second tie rod 25 and turn to the T place to stop by the U place, at this moment hinge can rotate, and makes the person in charge 1 turn to the W place to finish the horizontal folding action by the V place.

Among Fig. 6: 27. eccentric tommy bars, 28. handlebar stems, 29. clamping sleeves, 1/30.th 3 gear, 31. springs, 32. pipes

As shown in Figure 6, pull loose eccentric tommy bar 27, clamping sleeve 29 actions of the spring are upspring, and at this moment handlebar stem 28 becomes flexible and turns to the X places, and other end handlebar stem 28 ' turns to X ' to locate simultaneously, realized that interlock is folding, otherwise action are a deployed condition.

As shown in figure 10, AL (l)=120 ~ 140; 35 centimetres of type cars get 120

As shown in figure 11, preceding flower-drum shaft length (m)=70 ~ 100:35 centimetre type car gets 70

(n)=35 ~ 45; 35 centimetres of type cars get 35

Rear drum shaft length (m)=100 ~ 150; 35 centimetres of type cars get 100

(n)=35 ~ 45; 35 centimetres of type cars get 35

Wheel both sides steel wire angle (α) are the principal parameters of correction wheel circularity, the front and back flower-drum shaft size after the compression, its α value and 70 centimetres (28 ") large-scale bicycle, the α value of wheel flower-drum shaft size is suitable, and therefore 35 centimetres of wheels select for use n=35 to be suitable for.

Claims (1)

1. 35 centimetres of portable folding bicycles comprise the person in charge, handlebar, shelf bar, it is characterized in that: establish vertical direction foldable structure and horizontal direction foldable structure on the described person in charge; Establish the interlock foldable structure on the described handlebar; The shelf bar is transferred and is provided with wrapping cloth.
