Folding bicycle

Abstract

The invention relates to a folding bicycle, comprising a bicycle frame, a handlebar arranged at the front upper part of the bicycle frame, and a saddle arranged at the rear lower part of the bicycle frame. The folding bicycle is characterized in that a handlebar stem capable of rotating back and forth relative to the bicycle frame is arranged at the front end of the bicycle frame, a front and a rear saddle posts capable of rotating back and forth relative to the bicycle frame are arranged at the rear end of the bicycle frame, the front and rear ends of the saddle are respectively hinged with the upper ends of the front and rear saddle posts, the upper end of the handlebar stem is hinged with the front end of a first connecting rod, the rear end of a second connecting rod is connected with the lower end of the rear saddle post and rotates synchronously therewith, and the rear end of the first connecting rod is hinged with the front end of the second connecting rod. Compared with the prior art, the folding bicycle has the advantages that the handlebar and the saddle can be folded synchronously, so the folding is convenient; with the bicycle frame consisting of a first and a second bicycle frames, the integral structure of the bicycle is firm, and all parts are located between the first and second bicycle frames after the bicycle is folded, thereby causing the external structure of the bicycle to be simple.

Description

technical field [0001] The invention relates to a bicycle, in particular to a foldable bicycle. Background technique [0002] Folding bicycles are generally compact in structure and small in volume after folding, which is very suitable for people to carry when going out. Most of the existing folding bicycles are basically folded left and right along the vertical line of the frame, such as the "foldable bicycle" disclosed in the Chinese utility model patent No. ZL 95225197.3 (authorized announcement No. CN 2242842Y), The folding bicycle is equipped with a rotary pair type folding locking device at the lower end of the neutral tube, a pin hole is opened on the rotating pair type folding locking device, a spring locking pin is installed in the hole, a pull wire is drawn from the pin, and the It can be placed on any part of the car body. When folding, you only need to pull up the locking pin, and the front tripod can be rotated with the center tube as the axis until it is close...

AI Technical Summary

Problems solved by technology

However, it can be seen from the above folding process that the rear fork, handlebar and saddle need to be folded step by step in this folding bicycle, and the folding is time-consuming.

In addition, this folding bicycle has the same disadvantages as the folding bicycle given in the above-mentioned "foldable bicycle" that the frame is thin and the overall structural strength of the body is not high.
