Parallelogram steering mechanism two-handed assisted chromium alloy bicycle

Abstract

The invention relates to the field of bicycles. A parallelogram steering mechanism hands-assisted chrome alloy bicycle includes a steering handlebar, a steering sleeve, a front fork horizontal shaft, a front wheel axle frame, a front wheel assembly, a rear wheel assembly, a rear fork swing frame, Frame components, paired sprockets, transmission chains and gravity seats, as well as steering steel shafts, power-assisted linkages, tension forks and power-assisted swing rods, coaxial symmetrical square shafts are symmetrically arranged under the steering handlebars, and the upper ends of the front wheel shaft brackets are connected There is a front fork horizontal shaft, and two steering steel shafts are movable and fixed between the front fork horizontal shaft and the coaxial symmetrical square shaft to realize the synchronous swing of the steering handlebar and the front wheel axle frame, which solves the problem of bicycle steering; the coaxial symmetry The axis line of the square shaft is at the same height as the shaft center line of the pivot pin of the swing rod. When the steering handlebar swings back and forth, the power-assisted swing rod is driven to swing back and forth synchronously centered on the through hole of the support. The hole is pivoted in situ at the center, and the distance between the coaxial symmetric square axis and the front fork transverse axis remains constant.

Description

technical field [0001] The invention relates to the field of bicycles, and the international patent classification is B62M, in particular to a chrome alloy bicycle with a parallelogram steering mechanism that assists both hands. 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 one-leg impairment can't handle it at all, even healthy people can't control a bicycle even if one leg 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 disadvantag...

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
