Problems solved by technology

[0002] The most frequent trips in people's lives are short-distance travel, but currently there are few means of transportation suitable for short-distance travel. Tricycles have good stability and flexible steering, which is very suitable for short-distance travel, especially for the elderly and the disabled. With the aging of my country's population With the advent of modernization, the market prospect is very broad, but the existing tricycles are large in size and have few functions, which limit people's use. If the tricycle can be deformed like "Transformers", the problem will be solved.

Abstract

The invention discloses a folding tricycle. The tricycle can be folded into a two-wheel trolley. The technical scheme of the invention is that: the folding tricycle comprises a front face, a main beam, a pull rod, a chassis, a seat plane, a hook, a seat back, a fork arm, a pedal, a connecting rod, and other components. The front face is hinged with the main beam and the pull rod; the pull rod is hinged with the chassis; the chassis and the main beam are crossly hinged to form a front parallelogram; the main beam and the seat plane are hinged; and the seat back is hinged with the seat plane and the chassis to form a rear parallelogram. By opening and closing the hook which is arranged at the front end of the seat plane, the transformation between the parallelogram and the triangle is realized. When the hook is closed, the frame is two triangles, and the stability of the triangles makes the tricycle body firm; and when the hook is opened, the frame is two parallelograms, and the tricycle is folded into the two-wheel trolley by using the mobility of the parallelogram.

Description

technical field [0001] The invention relates to a tricycle, in particular to a folding tricycle. Background technique [0002] The most frequent trips in people's lives are short-distance travel, but currently there are few means of transportation suitable for short-distance travel. Tricycles have good stability and flexible steering, which is very suitable for short-distance travel, especially for the elderly and the disabled. With the aging of my country's population With the advent of modernization, the market prospect is very broad, but the existing tricycles are large in size and have few functions, which limit people's use. If the tricycle can be deformed like "Transformers", the problem will be solved. Contents of the invention [0003] The purpose of the present invention is to provide a folding tricycle, which can instantly fold the tricycle into a two-wheel handcart. [0004] In order to achieve the above object, the present invention adopts the following technic...
