Description

Two-wheeled manned tool

Technical Field

The utility model relates to a two-wheeled manned instrument.

Background

The bicycle has been invented for over two hundred years, and in the period of over two hundred years, people always try to improve and perfect various performances of the bicycle, so that the original toy type wooden horse bicycle is changed into various novel or leisure or sports bicycles which are deeply loved by people today, the development purpose of the bicycle is also changed into a tool for transportation, transportation and leisure sports from the earliest entertainment purpose, and the advantages of no noise, no pollution, light weight, simple structure, high quality, low price and convenient use and maintenance of the bicycle are continuously developed, so that the bicycle can be used as a tool for transportation, goods transportation, sports and competition, and is widely used by people. Particularly, nowadays, global carbon emission is increasingly serious and living environment is continuously deteriorated, green traveling of bicycles is more distinguished to be precious and important!

Although the traditional bicycle is closely related to the life of human beings and brings much welfare to human beings, some places which are not fully satisfactory exist in the using process of human beings, and the long-term existence of the problems is probably an obstacle influencing the large-scale popularization and the popularization.

Firstly, the riding posture of a person designed by a traditional bicycle is a slightly forward-downward type, and the design mode enables partial muscles of limbs such as arms, shoulders, waist and the like of the person to be subjected to static force for a long time, so that fatigue is easy to generate;

in addition, the saddle design of the traditional bicycle is not reasonable, the narrow saddle easily causes fatigue of gluteus maximus, the riding time is a little longer, the part of a human body contacting with the saddle can be painful, numb and even unconscious, and the saddle is very unfavorable for long-distance riding.

In addition, the traditional bicycle pedals rotate for one circle, the effective acting angle is not more than ninety degrees, most of the remaining rotating angles are invalid intervals, and the cycle is repeated, so that physical strength is wasted, working time is occupied, and the bicycle is not cost-effective.

Finally, the traditional bicycle has a high gravity center, a large windward side and a slightly accelerated speed due to the structure, and can bear large wind resistance related to the square of the speed, so that the physical strength of a rider can be exhausted quickly. Likewise, the high center of gravity is disadvantageous for the installation of rain shelters, while also not occupying the wind in safety.
