Abstract

The air power bicycle driven with air as one traffic means consists of bicycle body, air pressure generator, air storing device, driving system and other parts. After the on-off switch is turned on, the compressed air from the air storing device drives the executor in the driving system to drive the wheel for the bicycle to go forwards. During riding, compressed air may be replenished by the rider to the air storing device via the air pressure generator for the bicycle to run further. The air power bicycle is superior to traditional bicycle, which has great physical strength consumption, slow speed and hard upslope, and is suitable for use as body building traffic means.

Description

Air power bicycle

Technical field the present invention relates to a kind of aerodynamic force bicycle driven of utilizing.

Technical background is present, public bicycle drive system mainly contains the foot-operated and rechargeable battery dual mode of manpower, the foot-operated bicycle of manpower need consume a large amount of physical efficiency of cyclist, can't continue the state that obtains running at high speed, generally can only use in the short range among a small circle, adopt the rechargeable battery bicycle driven to be called Electrical Bicycle by people, Electrical Bicycle does not need to consume people's muscle power, but its load is light, speed is slow, storage battery is heavy again and be unfavorable for environmental protection, mileages of continuation limited (general each charging can only be travelled about 70 kilometers at most), and charging duration requires very long simultaneously, the service life of battery is short, generally use less than 2 years and just scrap, price is relatively more expensive again, and (50-100 unit/12V) is so the operating cost height.The objective of the invention is to provides a kind of simple to operate at the deficiency of above-mentioned existing two kinds of drive forms, can be in operational process replenishment system power, need not to consume electric power or gasoline equal energy source, low operating cost, pollution-free, and the bicycle that can continue to run at high speed.

Fig. 2 is the supplemental instruction to Fig. 1, is the structural representation that advances system.

Among Fig. 2: it is cylinder that 5-advances; 6-chain (being divided into chain and lower chain); The 7-flywheel; The 14-piston rod; The 15-propelling unit divides top push pedal and below arm-tie); The 16-travel switch; 19-rotates little axle; The 20-leading sheave; The 21-directive slide track

Fig. 3 is two the structural representation of the embodiment of patent of the present invention.

Among the figure: the 1-bicycle body; The 2-start stop switch; The 3-accumulator unit; The 4-directional control valve; 5-gas motor; The 6-cycle chain; 7-flywheel: 8-air pressure generating means; The 9-bicycle rear; The 10-filter; The 11-reducing valve; The 12-oil sprayer; The 13-governor; The 14-noise silencer

Summary of the invention the present invention is achieved in that as Fig. 1 and shows, after the rider takes bicycle 1, open start stop switch 2, pressurized air in the accumulator unit 3 is passed through filter 10 successively, reducing valve 11, oil sprayer 12, directional control valve 4 and governor 13 enter and advance is to promote piston rod 14 in the cylinder 5 to stretch out forward, the propelling unit 15 that is positioned at the piston rod top is from starting point A, advance along the AB direction, the top push pedal of propelling unit 15 promotes chain 6, and chain 6 drives flywheel 7, flywheel 7 drives bicycle rear 9, thereby makes bicycle integral body to overtake; After propelling unit 15 arrives the B end, travel switch 16 transmits a signal to start stop switch 1, start stop switch 1 sends signal enabling directional control valve 4 automatically, pressurized air in the cylinder is under the effect of directional control valve 4, be discharged from through governor 16 and noise silencer 17, enter cylinder 6 with stylish pressurized air through governor 16, piston 14 begins to return to the A end from the B end, below arm-tie pulling chain 6 motion backward together of propelling unit 15 drives flywheel 7 driving bicycle rears 9 and advances.After getting back to the A point from the B point, finish progradation one time.So move in circles, bicycle is constantly travelled forward.

Advancing the design of system is important component part of the present invention.Show that as Fig. 2 the design of piston rod 14 top push pedals and below arm-tie is a single load bearing, its bottom is connected with piston rod, and this connection is unidirectional activity, can around rotate little 19 forward (backward) make low-angle and rotate.When the piston forward impelling, the push pedal of its top drives top chain 6 forward, drives flywheel 7 and rotates, and advances thereby drive bicycle.In this process, the below arm-tie below slide on the chain, do not influence top push pedal acting; In like manner, when the below arm-tie in the process of operation backward to below chain acting, the top push pedal does not influence the lower pulling plate acting.Be subjected to the diametral load effect for reducing in the piston motion process, prolong the service life of cylinder, leading sheave 20 is installed on piston, directive slide track 21 is installed on bicycle rack, pulley 20 moves on slide rail 21, play the guiding role, and bears most radial effect power simultaneously.

In addition, advance the pneumatic apparatus of system can also adopt the torque output shaft of gas motor or air nutsetter, pneumatic angle grinding machine directly to drive sprocket shaft, advance, show as Fig. 3 thereby drive bicycle.The propulsive effort of patent of the present invention is an air, and working medium is inexhaustible, does not need to spend.Pump-down process is simple, and is free from environmental pollution, and cost is low, and pressure rating is low, safe in utilization.

Patent air pressure generating means of the present invention is various superhigh pressure Floor Pump, existing homemade foot-operated Floor Pump can produce the high pressure gas of 1Mpa, import Sigma Floor Pump even can reach 1.2Mpa pressure, so it is no problem manually to produce pressurized air, only need the storage tank of adaptive corresponding voltage withstand class to get final product.Except manual inflation's mode, can also utilize the crank motion of cylinder piston that Floor Pump is inflated and be sent to storage tank, to alleviate manual inflation's physical consumption.

Operation pressure in the patent cruising process of the present invention is 0.63Mpa, if the double strength cylinder of configuration Φ 40 (piston rod Φ 18) is as the pneumatic element that advances system, thrust can reach 1580N, and it is that the bicycle of 200Kg advances fast that pulling force 1260N, its power are enough to drive load.As disposing the gas motor, torque＜30N.m by using reductor, can improve power output, is mainly used in long distance and continues to provide acceleration/accel; Also the two can be combined driving.

Patent cruising speed of the present invention is 40 kilometers/hour, and F-Zero can reach more than hundred kilometers.By using one-way throttle valve, can make the electrodeless adjusting of running velocity.Cylinder running velocity in the market is divided into 3 classes: low speed 0.05～0.5m/s, and common high speed 3～17m/s reaches as high as 45m/s, and high-speed cylinder needs supporting shock absorber.With the cylinder piston running velocity of 3m/s, through transforming computing, the speed that its driving bicycle advances can reach 80 kilometers/hour.Certainly, bicycle moves under fast state needs examining through national related management department.

Patent of the present invention need be equipped with the working power of 12V direct supply as travel switch and start stop switch.

Except that bicycle body, the weight that other configurations of patent of the present invention are increased can be controlled in the 15Kg.
