Double-rear-wheel drive mechanism of bicycle

Abstract

A bicycle dual rear wheel drive mechanism comprises a disk, a power shaft, a crank, a pedal, a chain, a connecting rod, a dual power rear wheel structure, a power storage rack structure, an anti-deflection reverse tilt brace structure, a vehicle seat, a front wheel, a front fork, a steering handle, a mounting rod, a handlebar governor and a connecting pipe, wherein the power shaft is installed atthe middle position of the lower end of the power storage rack structure. The bicycle dual rear wheel drive mechanism comprises a disk, a power shaft, a crank, a pedal, a chain, a connecting rod, a dual power rear wheel structure, a power storage rack structure, a vehicle seat, a front wheel, a front fork, a steering handle, a mounting rod, a handlever and a connecting pipe. As that rear wheel, the pow motor, the connecting shaft and the rear gear disk of the invention are mutually cooperate with the disk, the double power can be provided and the vehicle frame can be pushed forward; The frame,storage box, battery, plug-in seat and storage pipe are arranged to facilitate the storage of batteries and rain-shielding tools, facilitate the sheltering of rainwater when raining, and prevent rainwater from eroding the frame and causing battery damage; Sliding pipes, buffer pipes, buffer springs and buffer rods are arranged so as to play a cushioning role when the frame is tilted, and preventthe frame from tilting and injuring the rider.

Description

technical field [0001] The invention belongs to the technical field of bicycles, in particular to a bicycle double rear wheel drive mechanism. Background technique [0002] Most traditional bicycles control the handlebars and front wheels of the bicycle by hand. People sit on the bicycle seat and use the power of their feet and legs to drive the pedals. A flywheel on the wheel keeps the bike going. The bicycle with this structure only relies on the legs to exert force, which wastes the energy of the gravity of the human body, and the posture is single, which is not conducive to exercising the body. If the riding time is too long, it will cause pain in the buttocks and legs. With the advancement of science and technology, the improvement of people's living standards, the pace of life has also been greatly accelerated, thus often ignoring physical exercise. People can only exercise the lower limbs when they use the above-mentioned bicycles, but the muscles of the arms cannot...
