Abstract

The invention discloses a full folding bicycle, and relates to transportation. At present, all bicycles can be only folded locally and singly, the invention aims to achieve a good folding effect to make up for defects and disadvantages of the bicycles. The full folding bicycle is a novel product adopting a double plate type frame proposal and breaking away from a tube type mode, and consists of a horizontal handlebar, a vertical handlebar, front and back wheels, foot pedals and a back seat upright post. The bicycle is crucially characterized in that: 1, a double-chain three-shaft four-wheel (also named a three-joint shaft) transmission system has multiple functions of speed ratio, intermediary agent, no falling of chains, and adjustment of tightness degree of the chains to achieve the aim of folding the back wheel; and 2, the size after the folding can be lessened in the length, width and height, and the operation is simple and convenient without other tools in the folding process and unfolding process.

Description

But full-foldable bicycle

Technical field

The vehicle

Background technology

Folding bicycle, along with development in science and technology, the raising that people require, existing multiple product has been made great contribution for society on the market.But carry out thinking from the angle of technology innovation, its conclusion is innovate more convenient carrying, the bicycle of also conveniently depositing, thus satisfy real people's demand to a greater degree, but the innovative idea of full folding type bicycle is just arisen spontaneously.

In the existing bicycle series product, the design plan that pursuit is convenient for carrying, all be to reduce wheel diameter and wheelspan, to reduce its dimensions length, the height of handlebar and the height of vehicle seat, take the mode conveniently disassembled ... the collapsible purpose of bicycle is to reduce the link for convenience, reduces parking space, is beneficial to and carries.Based on this present situation, be the innovative idea of feature but proposed the full folding type bicycle.The tubular structure that changes vehicle frame is a plank frame, makes that front and back wheel is all removable moves, and handlebar, vehicle seat, stretcher are all removable to be moved.Size after complete the folding can both diminish on a length and width Senior Three orientation, and folding process and expansion process, and is easy and simple to handle, do not need other instruments.

Summary of the invention

Can " full folding type bicycle " being the technology innovation theory, the technical scheme main points of the novel employing of the present invention be:

1. adopt the structure of double-plate vehicle frame to see Fig. 5, it is characterized in that: the hollow crossbeam (4-1) on the vehicle frame is cubic cast section The crooked body frame of vehicle body (4-2) is a channel-section steel type section

Weldering connects.

2. its transmission adopted two-stage chain is called double-stranded three four-wheels (claiming three connecting shafts again) driving system and sees Fig. 8

3. being provided with cross handle folded box (see figure 2) carries out laterally folded

4. being provided with to erect carries out the folded box (see figure 3) vertically folded

5. be provided with car front fork folded box (see figure 4) and carry out the back, make front vehicle wheel fold into the position of regulation to folding.

6. be provided with stretcher folded box (see figure 9)

7. the gathering mechanism of vehicle seat column (seeing Fig. 6 Fig. 1 Fig. 5)

8. shaft lock (see figure 7) after

The specific embodiment

But the present invention is with the simple and direct practicality of novel full-foldable bicycle, its overall dimensions can be decided according to wheel size, here the wheel of selecting for use is 14 o'clock, each needs the used material suggestion of part, can use high strength, the light aluminum alloy materials of High Performance, also can select high light strong matter plastics etc. for use for expendable weight, total weight is no more than 8 kilograms and is advisable.

Fig. 1 always illustrates 1. 2. 3. 4. 5. 6. 8. stretcher of 7. double-stranded three four-wheels (the claiming three connecting shafts again) driving system of back shaft lock of vehicle seat column of the hollow crossbeam of vehicle frame of front vehicle wheel folded box of folded box on the front fork of the flat box body of half dollar of part figure

The flat box of 2 cross handle half dollars: (1-1) the flat box body of semicircle, it is that to support that the right cross handle of the main framework of left and right sides cross handle (1-2) contains into box portion be that square (1-3) takes off the mouthpart movable axis, when its by (1-4) spring tension time (1-3) take off mouthpart be buckled in (1-5) on the box body right axle slightly be again the support (1-6) of spring to contain into box portion be square, it is the perpendicular handle that supports whole box body.

Operation: throw off from the flat box body of half dollar when (1-3) will take off the mouthpart movable axis, cross handle (right) comes off folding automatically.Otherwise, (1-3) take off the mouthpart movable axis and be buckled on the flat box of half dollar body, be to launch.

3 is perpendicular folded box: (1-6) perpendicular column and (2-1) front fork core junction one folded box is arranged, (2-1) down box is welded on front fork core column upper end (1-6), last box be welded on perpendicular end place (2-2) screw rod (2-3) slightly head be locked and buckle nose (2-5) folding that is opened at (2-4) on the front-wheel crotch and put down (1-6) formation 90 and spend and be folded in the 4th position of (consulting total scheme drawing) on the hollow crossbeam of vehicle frame.Otherwise (1-6) perpendicular folding is closed erecting, and (2-4) the button nose is buckled, and is expansion.

4 car front fork folded box: (3-1) fork core and (3-2) folded box arranged between the front truck wheel carrier in the front truck wheel carrier, (3-1) upper box cover be welded in the front truck wheel carrier fork core end place (3-2) down box be welded on the front truck wheel carrier (3-3) and buckle nose and open (3-4) folding and put down, form 90 degree front truck wheel carriers rolls over backward, be folding (consulting total scheme drawing 1) the 3rd dotted line position, otherwise (3-2) the front truck wheel carrier is rolled over (3-4) folding forward and is closed, (3-3) the button nose is buckled, and is expansion.

5 double-plate vehicle frames: (4-1) the hollow crossbeam of vehicle frame is a square tube type section

(4-2) the crooked body frame of vehicle body is a channel-section steel type section

Welding (4-3) is a body support, and effect (4-4) the direction seat that plays support and connection is a vitals of accepting vehicle seat column direction

6 vehicle seat column (5-1) vehicle seat column holding screws (5-2) are extracted the formation in-line with disposable the mixing up of vehicle seat column clip screw (5-3) vehicle seat column from the hollow crossbeam direction of vehicle frame seat, and straight fork is gone into (consulting total scheme drawing 1) the 5th position in the hollow crossbeam of (4-1) vehicle frame.

7 back shaft locks: (6-1) be a long high-wide flat box lock body, (each parts of (6-7) spring are assembled in respectively wherein with (6-2) dead bolt (6-3) axis handle (6-4) spring (6-5) handle, make it to become an independently lock body, be fixed on vehicle frame rear axle place with (6-6) screw, Yi Bian one.

Operation after (6-8) rear axle is pinned by (6-2) dead bolt, is promptly finished expansion.Otherwise (6-5) handle advances, and compresses that ((6-7) spring, dead bolt withdraws from simultaneously, promptly finishes once folding.

8 vehicle bodies: be that the top view of vehicle body and lateral plan (7-1) axis (7-2) of double-stranded four-wheel (claiming three connecting shafts again) driving system are that the folding frame (7-5) of paying of speed ratio folding shaft (7-3) rear axle (7-4) is double-stranded bar driving system (7-6) back shaft lock

9 stretchers: the top view and folded sides view and movable axis (8-3) stretcher base (8-4) spring shaft (8-5) rectangle of expansion lateral plan (8-1) handle (8-2) the spring rectangular pipe section that are stretcher

Operate: (8-3) move down and block, both finished once and launched by (8-2) spring movable axis.Otherwise (8-1) handle is opened, and promptly finishes once folding.

Though novel the changing greatly greatly of the present invention moves, and obtained some achievements, also should continue to optimize, particularly in appearance must be well-designed, can consider that if any small portable power the portable conventional components of brake can be selected voluntarily.
