Luggage cart type front drive folding tricycle

Abstract

The invention relates to a luggage cart type front drive folding tricycle which comprises a front wheel, a handlebar, a front fork tube, a fork tube, a transverse beam, a saddle, a rear wheel rack, rear wheels and pedals, wherein the front wheel is a large wheel, and the rear wheels are small wheels; a folding device is directly arranged at the upper part of the front fork tube; the folding device is hinged with the transverse beam; the transverse beam is of a double-tube structure; the arc-shaped forked rear wheel rack is directly and fixedly arranged in the same plane at the lower end of the transverse beam; two lower ends of the rear wheel rack are fixedly arranged on the axis of the rear wheels; a fork rack is fixedly arranged on the rear wheel rack; a positioning support leg is fixedly arranged downwards at the middle part of the fork rack; and the positioning support leg and the two rear wheels form a stable plane when the transverse beam is upright. The folding tricycle disclosed by the invention is simple in structure, convenient and rapid to fold, high in riding efficiency and high in stability, a luggage cart can be formed after the tricycle is folded up, the application is widened, and the folding tricycle is small in size and convenient to store.

Description

technical field [0001] The invention belongs to the field of vehicles, and relates to a folding tricycle, in particular to a luggage cart type front-drive folding tricycle. Background technique [0002] The defect of tricycle is that it takes up a lot of space, heavy in weight, and its storage and use are not very convenient, thus producing folding tricycle. In order to reduce the size and weight, most of the existing folding tricycles are folded on the middle part of the upper beam, the pedals, and the handlebars. The folding of the pedals and the handlebars is relatively simple and has been innovated to a certain height. It is to cause the frame to be unstable and the service life is limited. At present, the folding of the wheels and the saddle cannot be satisfactorily solved, resulting in insufficient improvement in the storage space of the tricycle after being folded. [0003] By searching, it is found that there are many patent publications on folding tricycles, but t...

Problems solved by technology

[0002] The defect of the tricycle is that it takes up a lot of space and is heavy, and it is not very convenient to store and use, thus creating a folding tricycle.

[0007] Through the comparison of technical features, the applicant believes that in the first document, the tricycle is rear-drive, and the crossbeam is folded twice, resulting in unstable operation of the vehicle; in the second document, the tricycle is front-drive, but the folding In the middle of the beam, the saddle is canceled, and a stand appears again. Although the horizontal space can be folded and reduced, the height space is increased again; in the third document, its form is similar to the application of the present invention, which is a pioneering method, but a Small-wheeled tricycles have low operating efficiency. Although the front fork tube is hinged at the root of the beam, it is folded up and down on the same plane, and the folding effect is average; at the same time, the entire structure, such as the casing, is complex and costly, which is not conducive to popularization.
