Abstract

The utility model relates to a folding chair type bicycle, which includes a driving component, a three-dimensional folding connecting component, and a folding chair. A long frame, a horizontal frame, and a horizontal shaft of the folding chair are respectively hinged with a short frame of the folding chair. The three-dimensional folding connecting component consists of a hinging shaft, an extensible rod, and a furcated sleeve. The driving component is positioned on and hinged with the extensible rod through the hinging shaft; the hinging shaft is rotationally connected with the bicycle frame of the driving component through a bearing and is fastened and positioned by a nut. The extensible rod is inserted into the furcated sleeve and is fixed by a fastening sleeve; the fork opening end of the furcated sleeve is cruciformly hinged with the horizontal shaft through a vertical shaft. The lower end of the long framework is provided with a folding frame and a universal wheel, the lower end of the short frame is provided with a direction finding wheel. The connection between the driving component and the folding chair of the utility model has a universal and three-directional DOF, can run on a bumpy curved road, can carry persons and articles, and can be ridden; after the driving component is folded, the bicycle becomes a folding chair type handcart. The bicycle can be fully folded for facilitating carrying, storage, and safekeeping.

Description

Folding chair form bicycle

Technical field

The utility model relates to a kind of vehicle, particularly a kind of folding chair form bicycle.

Background technology

Existing two-wheeled Folding Bicycle is convenient to carrying, is deposited and take care of very much, but it only is suitable for a people and rides, and inconvenience is manned or transport object; Traditional hand barrow can manned fortune thing, but can only can not ride by hand push.

Summary of the invention

The technical problems to be solved in the utility model provide a kind of not only can manned fortune thing, but also rideable folding chair form bicycle.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of folding chair form bicycle comprises driven unit, three dimensional fold link and folded seat; Folded seat is made up of long framework, short framework and horizontal frame, and long framework is hinged with short framework by bearing pin, and the left beam of horizontal frame is hinged with the back timber of short framework by hinged sleeve, and the two ends of horizontal shaft are hinged with short framework.The three dimensional fold link is made up of jointed shaft, expansion link and fork-shaped sleeve, and driven unit is hinged by jointed shaft and expansion link location, and jointed shaft is rotationally connected by the vehicle frame of bearing and driven unit, and relies on nut tightening location; The expansion link running-fit inserts the fork-shaped sleeve, and the small end of fork-shaped sleeve is provided with sleeve, and the intersection end of fork-shaped sleeve is hinged by vertical shaft and horizontal shaft cross.The right-hand member both sides of horizontal frame are provided with backing pin, and backing pin snaps in the crossbeam of long framework.The upper end of long framework is provided with flexible handrail, and the lower end of long framework is provided with folding stand and cardan wheel, and the lower end of short framework is provided with directional wheel.The cushion of driven unit is installed on the three joint telescopic props, and the pedal of driven unit is provided with folding step.

The beneficial effects of the utility model are:

1. being connected between driven unit and the folded seat has universal and three-dimensional degree of freedom, can rise and fall at height, travel on the rugged bend.

2. not only can manned fortune thing, but also rideable.

3. collapsible driven unit becomes folding chair form hand barrow.

4. can all fold, be convenient to carrying, deposit and take care of.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment 1 is shown in Fig. 1-2: a kind of folding chair form bicycle comprises driven unit, three dimensional fold link and folded seat; Folded seat 1 is made up of long framework 15, short framework 16 and horizontal frame 20, long framework 15 is hinged with short framework 16 by bearing pin 12, the left beam 19 of horizontal frame 20 is hinged with the back timber 18 of short framework 16 by hinged sleeve 17, and the two ends of horizontal shaft 11 are hinged with short framework 16.The right-hand member both sides of horizontal frame 20 are provided with backing pin 21, and backing pin 21 snaps in the crossbeam 23 of long framework 15.Lift the right-hand member of horizontal frame 20, horizontal frame 20 upwards can be rotated around back timber 18, superimposed with long framework 15; Draw long framework 15 and short framework 16 again in, folded seat 1 is folding.The upper end of long framework 15 is provided with flexible handrail 22, and the lower end of long framework 15 is provided with folding stand 14 and cardan wheel 13, and the lower end of short framework 16 is provided with directional wheel 9.

The three dimensional fold link is made up of jointed shaft 6, expansion link 7 and fork-shaped sleeve 10; Driven unit 4 is hinged with expansion link 7 location by jointed shaft 6, and jointed shaft 6 is rotationally connected by the vehicle frame of bearing 26 with driven unit 4, and relies on nut 5 tightenings location; Driven unit 4 is free to rotate with respect to jointed shaft 6 and connected folded seat 1.Expansion link 7 running-fits insert fork-shaped sleeve 10, and the small end of fork-shaped sleeve 10 is provided with sleeve 8, unclamps sleeve 8, but expansion link 7 retraction fork-shaped sleeves 10 are convenient to fold.The intersection end of fork-shaped sleeve 10 is hinged by vertical shaft 24 and horizontal shaft 11 crosses, and driven unit 4 can swing on the ground around the line of centers of vertical shaft 24.The two ends of horizontal shaft 11 are hinged with short framework 16, make driven unit 4 with respect to folded seat 1 bending up and down when the raised or sunken road traveling.Like this, being connected between driven unit 4 of the present utility model and the folded seat 1 has universal and three-dimensional degree of freedom, can rise and fall at height, travel on the rugged bend.

The cushion 2 of driven unit 4 is installed on the three joint telescopic props 3, and pedal is provided with folding step 25, is convenient to dwindle oad, folds.

Embodiment 2: be affiliated in the back of folded seat 1, as shown in Figure 3 after driven unit of the present utility model 4 is collapsible; Also quick release driven unit and three dimensional fold link become folding chair form hand barrow.Also folded seat can be drawn in as shown in Figure 4, unfolded frame 14 just becomes the light luggage car.

Embodiment 3: as compact internal combustion engine being installed on driven unit 4 or by battery-driven DC machine, just being become folding chair form boosted vehicle.
