Manpower tricycle

Abstract

The present invention provides a manpower tricycle which comprises a frame, a pedal mechanism, a driving mechanism, a front wheel and two rear wheels. Two side edges of the pedal are respectively connected with the front supporting rod and the driving mechanism through front and rear arms; and the driving mechanism comprises a grooved wheel, a rear supporting rod and a chain, and the two ends of the chain are fixedly connected with fixing points of the rear supporting rod and the rear arm respectively and wound on the grooved wheel and the small fly. According to the tricycle with the structure, a user can walk on lower steps, continuous driving is achieved in a small-amplitude moving mode, and physical output is greatly reduced; and moreover, the legs of the user do not need to be stretched greatly, the free control space is large, reciprocating pedaling is facilitated, and riding of the user is not affected. The driving force is alternately provided by the two rear wheels, so that the stable operation of the bicycle is ensured. Meanwhile, by arranging a sliding block mechanism or a reset spring, an auxiliary pedal is reset, the operation difficulty is reduced, and a folding mechanism is designed so that a user can conveniently carry and store the tricycle.

Description

technical field [0001] The invention relates to a vehicle, in particular to a manpower tricycle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may constitute prior art. During the process of realizing the present invention, the inventors have found at least the following problems in the prior art. [0003] Traditional bicycles, due to the circular pedaling movement, have low transmission efficiency and are relatively laborious. And when the pedal was in the vertical position, there was a movement stop and it was difficult to operate. When used in a sitting position, the power of the legs is completely used to drive, especially when the power of the legs is used for a long time, it is easy to make the legs fatigue; The range of motion is large, which causes great physical exertion of people and increases the difficulty of controlling the bicycle. [0004] Aiming at the problems of t...

AI Technical Summary

Problems solved by technology

However, in the actual sample manufacturing, it was found that since most of the mechanisms are installed near the center beam, the center beam is very bloated. When the user stands on the center beam and rides, his legs are spread wide, and the space for free manipulation is small, which affects the The user rides, which is not conducive to reciprocating pedaling
