Abstract

The utility model provides an improvement project of a bicycle which is comfortable to ride and stable to drive. The project of the utility model is characterized in that a saddle is a chair with a backrest; a direction handle is positioned at both sides of the saddle like the armrest of the chair. A rotation shaft of the direction handle is connected with the wheel fork of a rear wheel via a cardan shaft; the wheel fork and the rear wheel can be driven to change direction by that the direction handle moves up and down; a foot pedal and a chain wheel are arranged in the front of a front wheel, and drive the front wheel via a chain. The utility model has low gravity center and stable driving, and a rider can feel comfortable when riding on the chair.

Description

A kind of bicycle

The utility model relates to the manually driven vehicle, especially a kind of two-wheeled cycle of single driving.

Existing two-wheeled cycle is no matter which kind of structure all is to adopt to ride, because vehicle seat is to ride on, so all less triangle makes the people feel extremely uncomfortable, all be that both hands are steering handle during existing besides cycling, bipod is pedaled downwards, stretcher rotates under vehicle seat, so vehicle seat is higher, and the center of gravity of bicycle is raise, the cyclist gets on and off extremely inconvenient, particularly very easily occurs dangerous under the situation of more-person-more-vehicle.

The purpose of this utility model is exactly weak point little at vehicle seat in the prior art, that the vehicle body center of gravity is high, and a kind of improved bike tech scheme is provided.

For clearly demonstrating the technical pattern of this programme, now by a specific embodiment, and in conjunction with its accompanying drawing, the technical characterictic of this programme is described in detail.

Accompanying drawing 1 is the structural representation of the utility model embodiment;

Fig. 2 is the schematic top plan view of Fig. 1.

As can be seen from Figure, the bicycle of this programme has the vehicle frame 5 of an inverted triangle, at the middle part that vehicle frame 5 is put the beams in place vehicle seat 6 is housed, this vehicle seat 6 is the seats that backrest 8 is arranged, and steering handle 7 is positioned at the both sides of vehicle seat 6, as the handrail of seat, the rotating shaft of steering handle 7 is in the behind of backrest 8, direction of passage grip 9 connects a versatile spindle 10, and this versatile spindle 10 can adopt conventional Oldham's coupling to constitute, and then connects the wheel fork 11 of trailing wheel 12 at the other end of versatile spindle 10.This structure can be utilized the upper and lower swing of steering handle 7 to control the rotation of wheel fork 11 and the working direction of trailing wheel 12, thereby reach the purpose that maneuver vehicle turns to.Front-wheel 1 is contained on the vehicle frame 5 of vehicle seat 6 front lower places, and the flywheel 13 on the front-wheel 1 is connected with chain wheel 3 on being contained in front-wheel 1 front upper place vehicle frame 5 by chain 2, and stretcher 4 then is connected with chain wheel 3.

In this programme, vehicle seat has made backed seat into, stretcher and chain wheel move on to the front upper place of front-wheel again, changed the conventional mode of riding, the people is felt comfortably cool, simultaneously wheel diameter is reduced, reduce the height of vehicle seat, vehicle's center of gravity is moved down significantly, increased the stability of vehicle.Turning to by traditional front-wheel steering of vehicle changes rear-axle steering into, and steering handle is arranged in the both sides of seat, this can be specially with hand go controlling party to, use the change that gets final product the maneuver vehicle direction of rocking of arm or health, therefore, the disabled person that this structure can be fit to some no hand rides usefulness.This car is being ridden the time spent, because vehicle seat is low, can be seated at earlier that bipod lands on the car, holds steering handle, supports with foot-operated pedal one pin of living then, can stablize after the startup and travel.This shows, the utility model compared with prior art, its effect is conspicuous.

Embodiment illustrates in technical scheme, so no longer repeat.
