Multi-functional pneumatic bicycle

Abstract

The invention relates to a multi-functional pneumatic bicycle. The multi-functional pneumatic bicycle comprises a front wheel, a rear wheel and a unitized frame, wherein a cylinder and a control circuit are mounted on a front frame; a pneumatic motor is fixed on the side surface of a rear frame of the bicycle; a gear is mounted in a key slot of an output shaft of the pneumatic motor; a flywheel of the bicycle is mounted with a chain wheel; the gear is engaged with the chain wheel; blades are mounted between two spokes of the rear wheel; a rear wheel airbag is mounted on one side below a saddle; the lower part of the front wheel is clamped into a front wheel airbag; a push rod is mounted in a cylinder mounted on a front fork of the bicycle; the push rod is connected with a sleigh board; small crawler wheels are arranged at one ends of straight connecting rods; the straight connecting rods are connected with a curved connecting rod and a big crawler wheel; and the rear wheel, the big crawler wheel and the small crawler wheel are integrally connected with each other through a crawler belt. According to the multi-functional pneumatic bicycle provided by the invention, the multi-functional pneumatic bicycle is driven to move ahead by using compressed air and manpower as power; and the bicycle has dry land, snowfield and water walking functions. During walking on the dry land, the airbags and the sleigh board are closed up; during walking on the water, the airbags are used for supporting and the blade is used as paddles; and during walking on the snowfield, the sleigh board is driven by the cylinder to extend out downwards so as to eject up the front wheel, and the rear wheel is converted into the crawler wheels to run forwards. The multi-functional pneumatic bicycle provided by the invention is convenient and fast to switch.

Description

technical field [0001] The invention relates to a multifunctional pneumatic bicycle. Background technique [0002] Although modern people use bicycles less and less to travel, in order to solve the problem of the last few kilometers that buses cannot solve, free self-rental is still welcomed by everyone, but there are some problems in use of bicycles now, such as skidding in rainy days , When encountering waters without bridges, bicycles cannot come in handy. In the face of energy shortage and environmental pressure, the means of transportation continue to innovate, and the emergence of electric vehicles drives the development of bicycle technology. However, the disposal of hundreds of thousands of waste batteries every year is a difficult problem for a while. As a simple and green transportation tool, the use of human-powered bicycles There is still a lot of demand. [0003] Therefore, be necessary to design a kind of bicycle with arid, snow and water amphibious function....

AI Technical Summary

Problems solved by technology

The application is a brand-new bicycle without pneumatic drive: almost all of them are driven by small wheels; the structure is bloated, the speed is slow, and it is laborious; the front and rear are equipped with skis, and when walking on snow, it depends on the reaction force of the long pole ice blade to the ground It is inconvenient to push the bicycle forward and turn, and it is not safe to ride
