Hand-foot cooperative and chromium alloy oscillating bar driving bicycle

Abstract

The invention relates to the field of bicycles, in particular to a bicycle driven by a chrome alloy pendulum rod combined with hands and feet, including a handlebar assembly, a front fork assembly, a front wheel, a frame assembly, a drive system, a sprocket center shaft, a symmetrical sprocket, and a transmission chain , the rear fork assembly and the lifting seat assembly, as an improvement: the present invention adds a drive system, a triangular box is set on the frame assembly, especially a double-seat roller, and the double-seat roller can roll along the inner wall plane of the two sides of the box body, Let the power-assisted swing rod have the two-point support of the fixed pin of the swing rod and the double-seater roller on the left and right vectors. The power-assisted swing rod provides strong support for the swing car stand on the left and right vectors through the swing slider, which makes up for the fact that the universal joint connection block only It can give the defect of the vertical axial limit of the swing bike; especially the use of the buttocks of the body to act on the lifting seat assembly solves the new problem that the seat swing pin in the drive system cannot have height or front and rear displacement, so that every rider can enjoy Can be ridden in the most suitable working conditions.

Description

technical field [0001] The invention relates to the field of bicycles, and the international patent classification is B62M, in particular to a bicycle driven by a chromium alloy pendulum rod combined with hands and feet. Background technique [0002] Existing ordinary bicycles mostly rely on the alternating pedals of both legs to realize sports, and the alternating pedaling of left and right feet also causes transient force imbalance, and both hands can only grasp the direction and brake and assist the body to balance. Both hands can't help the legs at all, and people with impaired legs and feet can't handle it at all. Even healthy people can't drive a bicycle even if one of their legs is injured. The driving devices of bicycles in daily life are all of the rotary pedal type. The mechanism of alternately pedaling with both feet is like a crank linkage mechanism, which produces two dead points, the upper and lower, so it cannot perform work continuously, and there are disadva...

AI Technical Summary

Problems solved by technology

In order to allow both hands to give strength to both feet, someone uses the hand-crank mechanism of the disabled on the bicycle, such as the Hand-foot compound bicycle with double ratchet of a kind of hand-foot compound bicycle with double ratchet in US Patent US 9,056,653 B2. The mechanism brings left and right instability, and still fails to solve the inherent disadvantages of the upper and lower dead points of the swing pedal bicycle
