Abstract

The utility model belongs to a bicycle among vehicles. The vehicle frame center of gravity of the existing bicycle is equipped with a spring shock absorber, the left side of the vehicle frame is equipped with a booster pressure bar, the left side of the rear axle is equipped with a booster flywheel, and the rear fork is a flat rear fork. Utilizing the elastic force generated during riding, while slowing down the vibration, the booster lever acts the vibration energy on the rear wheel through the booster flywheel, so that the body increases the power to move forward. The utility model has the advantages of simple structure, low cost of newly added components, convenient installation, etc., and fully utilizes the characteristics of the bicycle itself undulating and bouncing during riding, turning disadvantages into advantages, and making the rider labor-saving and comfortable.

Description

The utility model belongs to a bicycle among vehicles.

Existing bicycle has multiple, but its main component all is to be made of vehicle frame, wheel, handlebar, front and rear fork, saddle, pedal, chain, gear, bearing and some other components. At present, there is also a kind of speed change gear, booster engine etc. installed on the bicycle, but all fail to make full use of the characteristics of the car itself, so that the cyclist is labor-saving and comfortable.

The purpose of the utility model is to provide a power-assisted bicycle which can make use of the characteristics of the bicycle itself and make the rider labor-saving and comfortable.

In the bicycle of the present utility model, a spring shock absorber is installed at the center of gravity of the existing bicycle frame; Change to a flat rear fork. Utilize the bumpy elastic force generated during riding, while slowing down the vibration, use the booster lever to apply the vibration energy to the rear wheel through the booster flywheel, so that the body increases the power to move forward, and the more uneven the road surface, the better the effect significantly.

Embodiments of the utility model are shown in the accompanying drawings.

Accompanying drawing is the structural representation of the utility model. Among the figure: vehicle frame (1), vehicle seat lifting button (2), spring shock absorber (3), booster pressure bar (4), flat rear fork (5), booster flywheel (6). A power-assisted flywheel (6) is adorned on the left side of the rear axle of the existing bicycle rear wheel, and a flywheel is respectively arranged on the left and right sides of the rear axle like this, and the flywheel on the right side is an original chain drive wheel, and the left side is a newly installed power-assisted flywheel (6). Change the original rear fork into a flat rear fork (5) that can increase the load-bearing, and fix it behind the central axis, and make it movable up and down on the fixed bolt. A spring shock absorber (3) is adorned at the center of gravity place of vehicle frame (1), and fulcrum is placed on the rear truck fork, and the method for connection can be above with iron pin, riveted below, but must have certain amount of activity. There is a seat lift button (2) for adjusting the lift under the seat, and a booster pressure rod (4) is installed on the left side of the frame (1) behind the seat, and is connected with the left side booster flywheel (6) with a movable shaft , the length of the booster pressure rod (4) can be determined according to the size of the vehicle body. In this way, when a person rides on the bike, the frame (1) and the booster lever (4) are pressed down, and the booster lever (4) then transmits force to the booster flywheel (6), and the booster flywheel (6) It also drives the rear wheels, and the frame (1) will drive the booster pressure rod (4) to move up and down from time to time due to the up and down elastic force generated by stepping on the pedals with both feet and the impact of the ups and downs on the rear wheels when the road surface is uneven. , so as to form a natural power-assisted effect on the rear wheels, making the rider feel labor-saving and comfortable.

The utility model has the advantages of simple structure, slow release of vibration, low cost of newly added components, convenient installation and the like. In particular, it makes full use of the ups and downs and bouncing characteristics of the bicycle itself during riding, turning disadvantages into advantages, and making the rider both labor-saving and comfortable.
