Description

Amphibian bicycle

The utility model relates to bicycle, is a kind of amph bicycle.

Existing bicycle is of a great variety, and the Regular Bicycle of single speed, many speed is arranged, and also has the narrower racing car of wheel, and the mountain bike of wheel broad comprises three-wheel vehicle with three wheels etc.All include vehicle frame, front fork, front and rear rolling wheel, direction handgrip, seat cushion, pedal and transmission device in its keystone configuration.The bicycle of this spline structure, its mode of motion is to drive wheel rolling with pedal by chain drive.As everyone knows, such bicycle can't move on the water.It is existing that can to make the utensil that similar bicycle amusement waterborne uses be a kind of waterwheel of stepping on waterborne, two pontoons, vehicle frame, seat cushion, pedal and transmission device, propeller and a yaw rudder about including in its keystone configuration, utilize the buoyancy of two pontoons that vehicle frame and people are held up, drive propeller by transmission device and rotate, make and step on waterwheel and advance.This waterborne when stepping on waterwheel and moving on the water stability better but advance slowly, the difficulty of turning lacks pungency, the match property of aquatic sports amusement.The inventor has consulted some data in the creation process of several years, yet there are no a kind of amphibious, particularly be suitable for the bicycle of riding on waterborne or the sandy beach.

The purpose of this utility model provide a kind of can be mainly places such as outdoor bathing place, park lake surface, snowfield or the marshy area Amphibian bicycle of riding by the sea, to open up a more later-model sports events, enrich people's entertainment life.

Realize the utility model of above-mentioned purpose, consist predominantly of vehicle frame, front fork, front and rear rolling wheel, direction handgrip, seat cushion and pedal, the forward and backward roller in the utility model is cylindric expanded letter wheel, and the diameter of rear roller is bigger than the diameter of front wheel.Adopting the purpose of expanded letter roller is in order to make it produce corresponding buoyancy, bicycle to be swum on the water surface.In the utility model, the pedal on-line equipment that drives the bicycle roller is on the turning cylinder of rear roller, but then pedal direct drive rear roller rotates.Also include a swing frame, an adjusting tension wheel and a zone face in the utility model and be provided with one group of driving slurry band of the paddle of opening and closing automatically; Swing frame is hinged in the center of rear roller with its center of oscillation that is positioned at the middle part, articulate tension wheel in its back-end, the front end of swing frame extends the handgrip rear, and is provided with the swing control pull rod thereon, drives the slurry band and is stretched on the wide edge face of wheel of rear roller and tension wheel.So Amphibian bicycle is identical with ordinary bicycle in the time of on land, rides pedal stretcher onboard, and rear roller promptly drives front wheel and rolls on the ground together and move ahead.When the utility model was put into ice, bicycle relied on the buoyancy of front and rear wheel to float on the surface, and the people rides when pedaling pedal, rear roller promptly rotates, at this moment, the driving slurry band that is stretched on its edge face rotates thereupon, because the slurry zone face is provided with paddle, and the direction of opening of paddle is met to water (flow) direction, so when paddle is rotated and when arriving the water surface, paddle just begins ＂ drinking water ＂, and along with the rotation of rear roller, draft amount is big more, and its propelling thrust is also big more.Be with because of slurry one group of paddle is housed, each paddle is just struck by turns, and then bicycle can advance on the water surface fast.

Be to improve the stability of the utility model in water, make it can bear bigger stormy waves and be in the left alone without help state of sailing of pulsation-free, the both sides of the driving slurry band portion of the utility model between rear roller and tension wheel are provided with and can downward open opening and closing regulate kickboard.Also can be hinged with on the main shaft of front wheel one be boots accordingly with the front wheel width at the bottom of the bouyant wheel shell of shape.The flexible kickboard of a ligulate is set in the inner chamber of the head of bouyant wheel shell again, and this flexible kickboard is connected with the regulating control that installs on handlebar with regulating line.When water surface stormy waves is bigger, perhaps need in the process of moving left alone without helply to get off during rest, as long as operating handle opens regulating kickboard, then bicycle has just obtained bigger buoyancy and stability.Be arranged on shape bouyant wheel shell and ligulate expansion plate wherein at the bottom of the boots in front wheel the place ahead, have the effect of protection front wheel on the one hand, can increase and regulate simultaneously the buoyancy of bicycle.In the bottom of this bouyant wheel shell a convex tendon sheet that plays the rudder for ship effect can be set also, to improve turning efficiency of the present invention.

The utility model has the advantages that, in face of the wide edge, rear roller and be arranged on the bouyant wheel shell at front wheel place and the adjusting kickboard at rear roller rear, make bicycle have enough buoyancy, can on the water surface, travel steadily or left alone without help leaning on.The driving slurry band that is stretched on the rear roller can be struck under foot-operated the driving continuously, makes bicycle fast forward.And the buoyancy of bicycle and waterpower propelling thrust can be regulated by bouyant wheel shell and swing frame.When need travel on land, snowfield or marshy area, as long as bouyant wheel shell or tension wheel suitably are pulled upwardly or put down, can adapt to different driving conditions, realize the purpose of motion.

A preferred embodiment of the present utility model as shown in drawings.Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

See that by figure the basic structure of present embodiment is similar to Regular Bicycle, include direction handgrip 1, front fork 4, vehicle frame 10, seat cushion 11, pedal 21 and front wheel 7 and rear roller 12.Forward and backward roller 7,12 in the present embodiment is cylindrical circular expanded letter roller, therefore, just can float when the utility model is placed in the water.A bouyant wheel shell 6 is hinged on the main shaft 8 of front fork 4 ends, be set with the flexible kickboard 3 of a ligulate in the inner chamber of this bouyant wheel shell 6, control kickboard 3 flexible controllers are regulating controls 2 that are installed on the handgrip 1, and flexible kickboard 3 is connected with regulating control 2 by regulating line 5.See by figure, on the main shaft of the Rear Ends/Dropouts part device rear roller 12 of vehicle frame 10, be articulated with a swing frame 20, the rear end of this swing frame 20 is articulated with a tension wheel 16, on rear roller 12 and tension wheel 16, be with one and drive paddle band 13, be connected with one group on it along with the variation of its strained condition paddle of opening and closing voluntarily, when paddle forwarded lower position to, paddle was opened voluntarily, when forwarding the top position to, paddle is combined on the slurry zone face.Paddle band 13 usefulness elastomeric materials in the present embodiment are made, and the tensioning degree on rear roller 12 is regulated with tension wheel 16.The front end of swing frame 20 is stretched and is put to the handgrip rear, and it is provided with tension wheel regulating control 9 and opening and closing control pull rod 22.Pedal 21 is packed on the turning cylinder 18 of rear roller 12 by connecting rod 19.In the present embodiment, respectively be hinged with one in the both sides of the swing frame 20 of 16 of rear roller 12 and tension wheels and regulate kickboard 14, perpendicular leaning against on the framework 20 when packing up, expansible is to level attitude when opening downwards.Number in the figure 17 is the screw that hangs tight of tension wheel 16.
