Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

Referring to figs. 1 through Fig. 4, a kind of Portable double-foldable bicycle that this utility model provides, before being sequentially connected with Wheel 4, chassis assembly and trailing wheel 12, chassis assembly includes handlebar 1, front frame 3, cross bar assembly, Rear frame 11 and vehicle seat 14, front-wheel 4 are connected in front frame 3, and handlebar 1 is detachably connected on front frame 3 upper end, and trailing wheel 12 is connected in Rear frame 11, cross bar assembly Including the front rail 5 being sequentially connected with from front to back, middle cross bar 7 and rear transverse rod 9, front rail 5 front end is fixing with front frame 3 to be connected, Front rail 5 rear end is connected by the first folder 6 with middle cross bar 7 front end, and middle cross bar 7 rear end and rear transverse rod 9 front end are by second Folder 8 connects, and rear transverse rod 9 rear end is fixing with Rear frame 11 to be connected, and vehicle seat 14 is detachably connected on rear transverse rod 9, the first folding The size that angle of inclination is A, A of folded device 6 is: 58 °≤A≤62 °, the size that angle of inclination is B, B of the second folder 8 is: 89°≤B≤94°.The cross bar assembly of the technical program is bi-fold configuration meant, and the angle of inclination of the first folder 6 be set to 58 °～ 62 °, the angle of inclination of the second folder 8 is set to 89 °～94 °, the first folder 6 and the second folder 8 all for tilting backwards, When the second folder 8 tilt backwards angle be set to 90 °～94 ° time, be i.e. comparable to the angle that turns forward of the second folder 8 It is set to 86 °～90 °, so makes handlebar 1 can tilt backwards after folding, conveniently tow；The front-wheel 4 of the technical program and trailing wheel 12 after folding, and front-wheel 4 and trailing wheel 12 are on same axis, and in use front-wheel 4 folds back, and trailing wheel 12 is rolled over forward Folded, save the space that bicycle takies, and front-wheel 4 is identical with the diameter of trailing wheel 12, then vehicle seat 14 dismounting is plugged into jack On, thus can tow smoothly；Again handlebar 1 is disassembled needs are put into knapsack when and be plugged on jack, folding The bicycle of poststack is rectangle structure, is conveniently placed in knapsack and carries walking, and the first folder 6 and the second folder 8 are all For bi-directional folded device, so can meet the folding custom of different use, such structure folds and dismounting is all simple, conveniently goes out OK.

More specifically, A=60 °, B=93 °, front-wheel 4 and a diameter of 25cm of trailing wheel 12, it is put into the height in knapsack after folding Degree not higher than 60cm, and front wheels and rear wheels is as bottom, will not damage bottom knapsack.

Handlebar 1 is removably connected with front frame 3 by vertical handgrip 2, and vertical handgrip 2 is expansion link, so can adjust handlebar Height, shake hands as collapsible or demountable structure, this makes it possible to more fully reduce folding in two, the left and right on handlebar 1 Space shared by rear bicycle.

Vehicle seat 14 is removably connected with rear transverse rod 9 by seat rod 13, and seat rod 13 is expansion link, so can adjust car The height of seat, can sufficiently reduce after folding the space shared by bicycle by expansion link.

Cross bar assembly is provided with at least one jack.The technical program is two, and one is used for grafting vertical handgrip 2, another Individual for grafting seat rod 13, can be with placement vehicle 1 and vehicle seat 14, the sky that saving folding rear bar and vehicle seat take by jack Between.

Rear frame 11 is provided with foot-operated 10, and Rear frame 11 is provided with motor driver.Realize voluntarily by foot-operated 10 The function of car stepped on by car.Power-assisted can be realized by driving means to ride, reduce the muscle power output of people, make to go out the most convenient. Driving means includes driving power supply and driving motor, and during using, driving power supply can be according to actual installation requirement Can also be arranged in rear transverse rod, so can more save space.

This utility model several structures in use are as follows:

1, not folded structure: the i.e. structure of cycling, is available for people and rides, referring in particular to Fig. 1.

2, dragging structure: make front wheels and rear wheels coaxial by rotating the first folder and the second folder, and vehicle seat is torn open Unload down and be plugged on jack, reach reduce space and tow with handlebar, referring in particular to Fig. 3.

3, portable structure: disassemble handlebar to be plugged on jack on the basis of dragging structure and be put in backpack Face, referring in particular to Fig. 4.

In sum, this utility model passes through to be provided with the first folder and the second folder on cross bar assembly, and The angle of inclination of the first folder is set to 58 °～62 °, the angle of inclination of the second folder is set to 89 °～94 °, so makes Handlebar can tilt backwards after folding, conveniently tows, and front wheels and rear wheels can be made coaxial, facilitates parallel towing, also Being put into inside knapsack together with bicycle after can being disassembled with vehicle seat by handlebar with folding, such enhanced convenience is gone on a journey, Thus improve the serviceability of bicycle on the whole.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model Protection domain within.
