Description

The hydrofoil bicycle

Technical field: the utility model relates to a kind of amusement on water fitness tool that exactly likes bicycle, especially a kind of hydrofoil bicycle.

Background technology: along with expanding economy, people's living standard improves constantly, and is also increasingly high to the requirement of quality of life simultaneously.Nowadays, the various amusements on the market, fitness tool are lifted and are unequal to number.But the fitness tool that is adapted at aquatic sports but seldom.The hydrofoil bicycle is exactly in order to satisfy everybody demand and the design-calculated of outdoor activity on the water.

Hydrofoil bicycle and standard bicycle have a great difference.On purposes, standard bicycle is mainly as a kind of vehicle of land use, to satisfy everybody trip needs.And the hydrofoil bicycle is positioned the amusement on water fitness tool, is devoted to make everybody in amusement and recreation, to reach the purpose of body-building.See that from profile both maximum differences are exactly that the hydrofoil bicycle does not have the indispensable structure of standard bicycles such as wheel, chain.

The hydrofoil bicycle is more similar with at present popular " leaper's waterborne " function ratio, but both are different again.We can say that the hydrofoil bicycle is " leaper waterborne " significant improvement structurally.The structure of " leaper waterborne " is between jet-propelled surfboard and spring stilt.The principle that it moves on the water is similar to the aerodynamics of aircraft flight." leaper waterborne " has the hydrofoil of two similar wings, when it in water the inside motion time, can notify by the current difference of hydrofoil upper and lower surfaces by Bernoulli's theorem and to produce lift.A bigger hydrofoil is mainly used in and produces lift and thrust in the back; A little hydrofoil in front, with control direction and stability.When the jockey drives it,,, advance to promote " leaper waterborne " Yi Bian on a little stretcher of its back, ceaselessly jump up and down with pin Yi Bian hold the fwd direction lever.It does not have spiral propeller; The action that its thrust is coordinated from driver's the jump action and the elastic deformation of whole physical construction mutually; So that producing, rear wing pats action; Hydrofoil is just as wing, thereby just a large amount of water drained generation thrust forward backward, promotes " leaper waterborne " with this and on the water surface, moves.

Because this principle of work of " leaper waterborne " makes it have following three major defects:

1) traveling comfort is poor: when the jockey drives, need to keep stance, ceaselessly jump simultaneously.Traveling comfort and nature of leisure when the jockey moves have directly been influenced.

2) physical demands is too big: make the machine planking, the jockey must be on pedal ceaselessly spring, if thereby stopping to beat will lose thrust and consequent lift is fallen in the water so.Because it is big especially especially to the loss of waist that the characteristics in its design make to jockey's physical demands.Common people play and will feel tired out especially so be not suitable for prolonged exercise in 5 to 10 minutes.

3) operating difficulties: when sliding, people and machine must keep balance, otherwise are easy to fall in the water, the most important thing is that beating of human body will be coordinated with the elastic deformation of machinery mutually otherwise are difficult to produce the thrust of advancing, and therefore the technical ability to the jockey has certain requirement.

Above shortcoming all ascribes the work principle of design of " leaper waterborne " to.Therefore wanting to overcome these defectives will change some original mechanical structure and principle of work.

The utility model content: to the deficiency of above-mentioned prior art, the utility model provides the hydrofoil that a kind of traveling comfort is good, physical demands is less, simple to operate bicycle.

For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: the hydrofoil bicycle comprises front wing, yaw rudder, handlebar, pedal mechanism, tubulose vehicle frame, vehicle seat, back wing support, rear wing, screw propeller, conical insert wheels, transmission shaft and flexible clutch.Front wing, yaw rudder, handlebar constitute steering hardware, and yaw rudder and handlebar are fixed together, and yaw rudder is fixed on the centre of front wing.The front end of tubulose vehicle frame is connected with handlebar, and the rear end is connected with screw propeller with flexible clutch through transmission shaft.Pedal mechanism is connected with the tubulose vehicle frame through the conical insert wheels.The vehicle seat front end is connected with the tubulose vehicle frame, and the lower end is fixed on the rear wing through the back wing support.

The hydrofoil bicycle is exactly the different of mechanical drive and power mode with " leaper waterborne " maximum difference." leaper waterborne " is the beating action that is transformed into rear wing through the rhythmical jump of jockey, with this power that advances as hydrofoil.And the hydrofoil bicycle is more as bicycle, and it is stepped on through the driver and pedals pedal and drive screw propeller and rotate and produce power, produces lift by former and later two hydrofoils during motion.The hydrofoil bicycle has also incorporated other advantages of bicycle simultaneously, and the jockey need not be moved on one's feet again.

The principal feature of hydrofoil bicycle is:

1) traveling comfort is better: owing to produce the difference of power mode, needn't as original, stand and beat but the jockey is sitting in to pedal above the saddle and steps on pedal, drive screw propeller and produce power.Both hands are held handlebar and are controlled direction, have avoided the unnecessary waste of muscle power.

2) physical demands is less: produce power with waist and rhythmical the beating of health before needn't looking like, but the jockey is sitting in to pedal above the saddle and steps on pedal, the drive screw propeller produces power, the strength of major requirement shank.Mode of motion is with basic identical by bike, and this should be unchallenged for we of bicycle first big country.

3) simple to operate: the jockey can almost not require jockey's technical ability as the light hydrofoil bicycle of controlling by bike, more need not accept special training.Only need when practical operation, practise regulating the skill of centre of body weight, will soon grasp its hints on operation.

The specific embodiment:

Like Fig. 1-shown in Figure 6: the hydrofoil bicycle comprises front wing 1, yaw rudder 2, handlebar 3, pedal mechanism 4, tubulose vehicle frame 5, vehicle seat 6, back wing support 7, rear wing 8, screw propeller 10, conical insert wheels 11, transmission shaft 12 and flexible clutch 13.Front wing 1, yaw rudder 2, handlebar 3 constitute steering hardware, and yaw rudder 2 is fixed together with handlebar 3, and yaw rudder 2 is fixed on the centre of front wing 1.Front wing 1 time produces a fraction of lift in work, cooperates the effect of mainly playing balance with rear wing 8, thus when rotating handlebar 3 yaw rudder 2 also and then rotation play the effect that turns to.The front end of tubulose vehicle frame 5 is connected with handlebar 3, and the rear end is connected with screw propeller 10 with flexible clutch 13 through transmission shaft 12.Pedal mechanism 4 is connected with tubulose vehicle frame 5 through conical insert wheels 11.Vehicle seat 6 front ends are connected with tubulose vehicle frame 5, and the lower end is fixed on the rear wing 8 through back wing support 7.The two ends of rear wing 8 are provided with wing tip winglet 9.

To be pedal mechanism 4 change the power of human body shank input the shp of transmission shaft 12 into through conical insert wheels 11 with the actuating unit of hydrofoil bicycle, and transmission shaft 12 is through the inside of bearing installation at tubulose vehicle frame 5 with flexible clutch 13.After vehicle frame 5 knees change certain angle through flexible clutch 13 with the rotating shaft moment of torsion, pass to screw propeller 10 and produce the thrust of advancing with this.

Back wing support 7 is joined together to form a triangle (like Fig. 1) with tubulose vehicle frame 5 and rear wing 8; Back wing support 7 links together with rear wing 8 and also forms a triangle (like Fig. 3); This spline structure is promptly firm simply again; No matter because be that hydrofoil bicycle or " leaper waterborne " produce current difference up and down and produce lift at aerofoil when relying on current to flow through the front and back hydrofoil; So the overall weight of body is more gently good more under the prerequisite of proof strength; Demanded power output to the thrust and the person of riding is just little like this, because the horsepower output of common people by bike the time is about 500W according to statistics, the power under the maximum force of explosion of better sportsman is generally about 1000W.Therefore selected material mainly is a high strength aluminum alloy; Strength-to-density ratio and the higher materials of stiffness-to-density ratio such as composite material (comprising the compound of metallic material and composite material) and highstrenghtpiston; Can use the high strength aluminum alloy section bar like vehicle frame; Hydrofoil alleviates the body total weight with making such as composite materials with this.

Wing tip winglet 9 is the one section winglet that is connected the back tip extension, and its effect is to reduce induced drag.Because the hydrofoil upper surface is crooked than lower surface, its lower surface rate of flow of fluid low pressure is high when motion, and hydrofoil upper surface flow velocity high pressure is low; Therefore the high pressure liquid cognition below the hydrofoil flows to the hydrofoil upper surface along the spanwise of rear wing; The difference of pressure that has reduced last lower aerofoil has thus promptly reduced the lift of hydrofoil, because hydrofoil is proal, therefore also can produce the eddy current of spiral at the wing tip afterbody; The loss part energy has reduced the efficient of hydrofoil.Therefore, in its end a wing tip winglet is installed and is reduced the efficient that induced drag improves hydrofoil.

The core part of the utility model is to change the principle that the hydrofoil onward impulse produces through the combination that utilization is similar to this structure and the screw propeller of transmission mechanism of bicycle; Next is the utilization of simplifying design and wing tip winglet of animal economy framework; Make it have comfortable operating characteristic easily, succinct profile attractive in appearance and power transmission performance efficiently.
