Abstract

The utility model discloses an electric (manpower) foldable bicycle belonging to two-wheel bicycles, in particular to a foldable electric (manpower) bicycle. Based on the foundation of a traditional foldable bicycle consisting of a front wheel, a back wheel, a frame, a gemel and a drive sprocket, the utility model is characterized in that a rotary shaft connecting and separating the gemal of the frame is vertical to the frame lengthways. The front and back parts of the frame are folded lengthways and an obtuse angle is formed when the front and back parts extend. The bicycle has the advantages of simple and reasonable structure as well as low cost and can be still adapted to running on a road with certain fluctuations when adopting a trundle.

Description

Electronic, manpower Folding Bicycle

Technical field

The utility model belongs to, two-wheeled cycle, particularly electronic (manpower) Folding Bicycle.

Technical background

The hinge of traditional folding bicycle is contained in the vehicle frame middle part, and its rotating shaft is perpendicular to the ground, and the vehicle frame front and rear part is laterally folded.This folding bicycle is because what adopt is laterally folded structure, and its hinge catch gear needs bigger power when therefore launching, and the front and rear part that could guarantee vehicle frame otherwise will occur swinging on same straight line, influences to ride and bicycle service life; Ride in order to scrunch, the wheel of this car is all done greatlyyer, and weight and cost that this has just increased car load also are not easy to folding carrying, and therefore can not give full play to the folding benefit of bringing; If will adopt electricity to drive, though wheel can be changed the very difficult adaptation of little, straight body frame structure for automotive the road traveling of fluctuating is being arranged, or carrying out topping bar.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of electronic (manpower) Folding Bicycle, and it is simple in structure and reasonable, and cost is low, and still can adapt to when adopting trundle is having the road traveling of certain fluctuating.

Solving the scheme that technical matters of the present utility model adopts is: at traditional being made of on the folding bicycle basis front-wheel, trailing wheel, vehicle frame, hinge and driving chain wheel, folding hinge is connected the vehicle frame that separates with rotating shaft with the vertical vertical and parallel ground-surface mode of vehicle frame, and the vehicle frame front and rear part forms an obtuse angle when becoming longitudinal folding structure and front and rear part expansion.

The hinge of this car adopts longitudinal folding structure, thereby can guarantee that vehicle frame is upon deployment vertically at same straight line, the possibility of having eliminated the swing about front and back wheel in service so can avoid the undue wear of union piece and rotational parts, therefore can increase the service life greatly; The front and rear part formed an obtuse angle when vehicle frame launched, just in time this position is overhead higher, still can satisfy when wheel is dwindled to top bar or do not clip ground at the fluctuating road traveling, therefore can alleviate car weight thus, cost-cutting has also really reached the portable purpose of folded bicycle; Vehicle frame launches to have constituted stable triangle with ground, and when riding, the folded edge of vehicle frame tightens mutually, meets the stress characteristic of hinge.

The specific embodiment

Referring to Fig. 1,3, this car is in traditional mainly being made of on the folding bicycle basis front-wheel 1, trailing wheel 2, vehicle frame 3, hinge 4 and driving chain wheel 5, front and back two parts of vehicle frame 3 are connected with longitudinal folding structure, and the front and rear part forms an obtuse angle when launching, that is, the rotating shaft of folding hinge 4 is with the vertical vertical of vehicle frame 3 and be parallel to ground.When vehicle frame 3 launches, the front and rear part is vertically in line, form stable triangular structure with ground, when riding, the folding hinge 4 of vehicle frame 3 is subjected to the power vertical with it, and the interface of front and back vehicle frame 3 bears the people's that rides pressure, and body weight is heavy more, then the pressure at interface place is big more, in conjunction with also tight more.Adopt small wheels when the walking of rugged road surface, can not clip ground, hold handlebar stem 7 after folding and just can move easily.Handlebar stem 7 lower ends of this bicycle have the hinge 9 that links to each other with the dwang 8 of front-wheel 1, be with fixed cover 10 on the handlebar stem 7, when riding that fixed cover 10 is drop-down, can limit the rotation of 8 of handlebar stem 7 and dwangs, if will draw on the fixed cover 10, the restriction that handlebar stem 7 and dwang are 8 is eliminated, collapsible (seeing Fig. 2 for details).See Fig. 3, when scheme of the present utility model was used for the dual purpose car of small wheels, pedal 11 and hinge wheel 5 should be loaded on the position by folding hinge 4 of vehicle frame 3, and be overhead higher herein, can guarantee not clip ground.Motor 14 is loaded on the rear portion of folding stand 3, just can easily power be passed to trailing wheel.

Claims (3)

1, a kind of electronic, manpower Folding Bicycle, mainly form by front-wheel, trailing wheel, vehicle frame, hinge and driving chain wheel, the rotating shaft that it is characterized in that connecting the hinge that separates vehicle frame is vertical vertical with vehicle frame, and the vehicle frame front and rear part is longitudinal folding and form an obtuse angle when launching.

2, by the described Folding Bicycle of claim 1, the handlebar stem lower end that it is characterized in that bicycle has between dwang with front-wheel has hinge to be connected, and is with fixed cover on the handlebar stem.

3,, it is characterized in that pedal and hinge wheel are loaded on the position by folding hinge of vehicle frame by the described Folding Bicycle of claim 1.
