Section three of U-shaped expansion bracket before being compressed to together；
Backrest and rear U-shaped expansion bracket fold：Backrest U-shaped frame is rotated forward about 10 degree, backrest alignment pin is retracted and pinned,
Then backrest U-shaped frame back rotation is folded to and be attached on rear U-shaped expansion bracket first segment, now the bottom compression of backrest U-shaped frame
Rear first pin buckle so that the tail end of lock have left the second section position-arresting groove, backrest U-shaped frame and rear U-shaped expansion bracket first segment one
Saved with rear U-shaped expansion bracket second is folded to, while the lower end of rear U-shaped expansion bracket first segment opens rear second lock, so far
U-shaped expansion bracket first segment, rear U-shaped expansion bracket second save and backrest U-shaped frame all folds into minimum position afterwards and complete backrest and
U-shaped expansion bracket folds afterwards；
M framves fold：M frame fixed plates are lifted, rotation M frame fixed mounts make it be buckled in the upside of the 4th section of M framves, make whole M framves
Fold up；
Pedal folds：It is rotated up right-hand tread plate swivel mount, drives hook to rotate simultaneously, when rotates to certain angle aft hook
On hook steel ball fall into the hook fixing hole of running-board bracket, hook stops operating, and now down rotates pedal swivel mount, when
The bottom that pedal swivel mount touches hook is turned to, continues to rotate in right-hand tread plate to running-board bracket, pedal, which folds, to be completed, and is hung simultaneously
Hook is also reset to original position.
Present inventive concept is novel, and reasonable in design, compact-sized, vehicle does not have any screw in folding process, needs to the greatest extent several
Second is just deployable or folds, and can be folded into the shape of push-and-pull car or both shoulders bag, and mobile storage is very convenient；Pin can during traveling or so
Alternately to trample left and right pedal, meet body mechanics's principle, while reach the purpose of sport and body-building and traffic means of transport, and lean on
Back of the body design makes waist buttocks lean against the intensity that can be lessened fatigue significantly on back；Great sense of the times, it is adapted to above and below City Youth men and women
Class uses, applied widely, is the vehicles of a new generation.

[embodiment]
The invention will be further described below in conjunction with the accompanying drawings, for the structure and principle of this device people professional to this
It is very clear.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to limit this
Invention.
As shown in Figure 1, Figure 2, Figure 3 shows, the present invention by handle, preceding wheel assembly, rear wheel assembly, M framves assembly, preceding U-shaped expansion bracket,
Pedal assembly and rear U-shaped expansion bracket composition.
Handle includes direction assembly and rotating handles, is the structure of rotating handles in the square frame of the upper right corner referring to Fig. 4, in figure
Decomposing schematic representation, direction are top plate assembly top, and bottom is the middle connecting rod for being provided with cavity, and top plate bottom is provided with two groups of rotations
Handle hand, rotary shaft chip are arranged at connecting rod top, and rotary shaft chip connection handle shrinks rotary shaft, and rotating handles can be along rotation
Rotating shaft chip rotary folding is to direction the cavity in assembly lower coupling pole, and U-shaped is stretched before assembly bottom is arranged connection by direction
Contracting frame, direction are top plate assembly top, and bottom is the middle connecting rod for being provided with cavity, and top plate is respectively arranged on the left side and the right side direction
Fixing groove, top plate bottom is provided with two groups of rotating handleses, and every group of rotating handles includes：Rotary shaft chip is arranged in connecting rod
Portion, rotary shaft chip connection handle shrink rotary shaft, and handle shrinks rotary shaft and axis connection in handle, handle interior axle lateral ends
Provided with shaft-cup in handle, interior shaft-cup chute is offered in the middle part of shaft-cup in handle, four-piece type handle is mutual by four arc connection sheets
Be hinged to form, four-piece type handle is set in ovalizing deflection and put, and ovalizing deflection set rectangular in cross-section, ovalizing deflection set can be by four
Formula handle struts rounded, and ovalizing deflection set side opens up fluted, and spring, four-piece type handle interior side company are provided with groove
Handle fixing axle is connect, handle fixing axle is provided with handle clip, and handle clip is engaged fixing groove with direction.
During folding, four-piece type handle is pulled outwardly, makes handle clip departure direction that fixing groove, order pin direction is (left
Handle direction is opposite) 90 degree of rotating handles, then handle is contractd forward and exposes shaft-cup in handle, at the same time due to little spring
Effect makes ovalizing deflection set leave four-piece type handle, and four-piece type handle can roll ovalisation by circle, be rotated down 90 degree and push away
Enter handle and shrink chute.The slope groove of shaft-cup bottom simultaneously opens the axis one of bottom in handle, another handle
Contraction method is identical.
