Embodiment Construction

[0026] The following implements to further describe the present invention in conjunction with the accompanying drawings.

[0027] Fundamentally different from traditional and modern car body structure assemblies and transmission methods, a three-stage telescopic tube (19) has been developed, which is arranged in horizontal and vertical double tubes, with the central axis tube (26) and the rear wheel fork (23) , the upper casing is connected in a matching way, which simplifies the manufacturing process and is highly interchangeable. The star-shaped large toothed plate (9) overlaps with the rear wheel (12) at a 60-degree angle, greatly compresses the folding size, and folds the shelf (16 ), the saddle tube (20), the lower end is provided with a shaft sleeve and a locking handle, and when folded, the shelf is turned forward by 180 degrees in an indexing manner, and the front wheel (2) and the handlebar (6) can be tilted axially forward and backward to 30-degree angle, increasing ...

Abstract

The invention discloses an ultra small-sized bicycle with special stepless speed regulation structure, which is characterized in that essential differences occur between the traditional technical structure and the modern technical structure as well as the traditional drive mode assembly and the modern drive mode assembly. By adopting a concept on innovation, a third-grade extension tube star-type big chainwheel is superposed with a 60-degree angle of the extension semidiameters of rear bicycle wheels. Toothed chains are driven in a stepless amplitude and speed change manner and the bicycle wheels realizes the stepless speed regulation in a drive manner, which is applicable to various walking machineries, in particular to the ultra small-size bicycle, thereby solving the problem of a core transmission assembly, greatly improving the off-road performance and reducing the total weight and volume of the bicycle. Therefore, a comparatively ideal and perfect modern vehicle is provided and can be a beautiful scene.

Description

technical field [0001] The invention belongs to a non-motorized human traffic device, and is a bicycle with a stepless speed regulation ultra-miniature special structure. Background technique [0002] The invention and production of bicycles has made great achievements for human beings for more than a century. It has brought great convenience for people to travel and carry things, greatly liberated productivity to a certain extent, and made great contributions to society. China is a major producer of bicycles, with several billion bicycles. It is known as the kingdom of bicycles, and its annual export volume is more than tens of millions, which is quite impressive. Along with the development and progress of social urbanization, traditional large-wheeled bicycles have shown clumsiness, volume, storage space, weight, etc., especially can not be carried to bring a lot of inconvenience to people's travel. Bicycle is a cheap and convenient means of transportation. In order to al...
