Shock absorbing bicycle

Abstract

The invention provides a shock absorbing bicycle. The shock absorbing bicycle comprises a front wheel part, a driving part and a rear wheel part. A frame and a rear fork form a scissors-shaped lever principle; a seat cushion is arranged right above a rear wheel; a handlebar is inclined towards the rear wheel to be convenient for a rider to master the steering direction; the position of the rider is integrally on the rear wheel; however, the gravity of the rider is still in the middle of the frame; as a movable connecting pin for the rear fork and the frame is arranged close to a front wheel and a rear shock absorber is arranged on the frame between the two wheels, the symmetric up-and-down moving space of the rear wheel and the seat cushion is increased and the rear fork and the frame form a big scissors shape. A bottom bracket and a crankset overrun a middle position between the two wheels and are positioned on the rear fork close to the front wheel; the rear fork is especially long and extends to a position close to the front wheel after overrunning the middle position between the rear wheel and the front wheel; the rear fork is connected with the frame through a rear fork movable connecting pin; and the handlebar is inclined to a position right above the middle position between the rear wheel and the front wheel; therefore, it is very comfortable for the rider during riding the bicycle by sitting on the seat cushion above the rear wheel.

Description

technical field [0001] The patent of the present invention relates to the field of bicycles, in particular to a shock-absorbing bicycle. Background technique [0002] Commonly used ordinary two-wheeled shock-absorbing bicycles have relatively poor shock-absorbing effect, and the seat cushion is relatively small without a backrest. It is very uncomfortable for the rider to sit on it, and the riding is not comfortable enough. Close to the rear wheel, the movable connection pin between the rear fork and the frame is also close to the rear wheel, so the rear fork is relatively short, the length of the rear fork does not exceed the middle of the front and rear wheels, the seat cushion is close to the middle of the two wheels on the frame, and the handlebar is close to the middle of the two wheels. The position of the front wheel, the center shaft and the crankshaft do not exceed the middle position of the two wheels. The position of the rider is also on the frame between the two ...

AI Technical Summary

Problems solved by technology

[0003]Aiming at the deficiencies in the above-mentioned technologies, the present invention provides a simple structure, comfortable ride, good damping effect, flexible handling, since the front wheels are steerable wheels, the rear The wheel is the driving wheel, the frame is very simple, no complicated steel structure, mainly fixed by a steel pipe, the seat cushion is on the frame directly above the rear wheel, the rear fork is relatively long, and the length exceeds the middle position of the front and rear wheels, extending directly To the position close to the front wheel, it is fixed with the frame through the movable connecting pin, and the rear shock absorber is set on the frame at the middle position of the two wheels. It is still mainly distributed on the frame between the two wheels, the front fork is tilted backward, and the handlebar and stem are close to the rear wheel, which is convenient for the rider to steer and control. This shock-absorbing bicycle is the same size as an ordinary two-wheel shock-absorbing bicycle In combination with the lever principle, the rear fork is extended beyond the middle of the two wheels on the frame, the seat cushion is set on the rear wheel, the rear shock absorber is on the frame between the two wheels, and the rear fork and the frame form a Large scissors shape, the seat cushion is symmetrical to the rear wheel, there is a large-scale up and down movement space through the rear shock sensor, so that the shock absorption distance increases, combining the advantages of shock absorption bicycles and recumbent bicycles, it solves the portability of shock absorption bicycles, Comfort, versatility, handling, and high cost of the frame, reducing the waste of resource materials, labor and cost
