Description

Foldable two-wheel vehicle and multifunctional folding box thereof Technical Field The invention relates to the technical field of two-wheelers, in particular to a folding two-wheeler and a multifunctional folding box body matched with the folding two-wheeler. Background Folding bicycles are increasingly favored by urban commuter due to their convenience in storage and portability. However, the folded two-wheeled vehicle has a small volume, but is irregular in shape, and is not convenient to carry, and particularly, is difficult to properly place when taking public transportation means such as buses and subways. In the prior art, the existing folding bicycle is transported mainly through a trunk of an automobile, or a simple two-wheeled carriage is provided, but most of the folding bicycle is simple in structure and single in function, and can not meet storage requirements in riding and carrying requirements after folding. Therefore, there is a need for a multi-functional folding case that can be used as a riding trunk as well as converted to a trailer. Disclosure of Invention The present invention aims at solving the drawbacks of the prior art and has a main object to provide a compact folding box for a two-wheeled vehicle. When the two-wheel vehicle is in a folded state, the folding box of the two-wheel vehicle can be unfolded to serve as a small trailer for carrying the folding two-wheel vehicle, thereby being convenient for carrying and taking public transportation means such as buses and the like. The two-wheeled vehicle can be folded by double-section folding, overturning the handle and the telescopic front wheel rod. In order to achieve the above purpose, the present invention adopts the following technical scheme: the utility model provides a multi-functional two wheeler folding box, wholly is symmetrical structure, includes mainboard, back plate, curb plate, baffle, main support pipe and floor mechanism. Two sides of the main board are hinged with the two rear boards respectively, the two rear boards are hinged with the two side boards respectively, and the two side boards are provided with baffle plates in a sliding mode.
