Foldable bike frame

Abstract

A foldable bike frame is mainly composed of a steering device (1) installed below a steering rod, a front bike frame body (8), a rear bike frame body (19), a lower supporting bike frame body (9) and a lock catch device. The foldable bike frame is characterized in that the lower supporting bike frame body (9) with connecting lugs (7 and 23) at the two ends is arranged to be a damping device. As the lower supporting bike frame body (9) is arranged to be the damping device, it is unnecessary to additionally install a damping device on the bike frame, the damping purpose can be achieved, the structure of the bike frame can be simplified, and the cost can be lowered. As the front bike frame body (8) and the lower supporting bike frame body (9) are hinged to the steering device (1) and the rear bike frame body (19) through connecting shafts via connecting lugs, the steering device (1) and the lower supporting bike frame body (9) can be rapidly folded, and the purposes of saving space and facilitating carrying are achieved.

Description

technical field [0001] The invention belongs to a folding bicycle and a light folding power vehicle, in particular to a folding frame of the folding bicycle and a light folding power vehicle. Background technique [0002] Bicycles are widely used in the world. With the development of science and technology, bicycles tend to be simple, light and portable folding bicycles. Due to these advantages, folding bicycles and light folding power vehicles have become more and more popular in recent years. focus on. The folding of a bicycle is mainly to fold the front and rear wheels. The key to folding the front and rear wheels is the folding of the frame. There are many styles of folding frames on the market, but the frame of a general folding bicycle is still very large after being folded. , It is not very convenient to carry. Although some frames can be folded a little smaller, but because of too many folding joints, the folding speed is very slow. [0003] In the prior art, the C...

AI Technical Summary

Problems solved by technology

Although this kind of folding vehicle frame solves the problem that the vehicle frame of a general folding bicycle is folded, the volume is still very large, and it is not very convenient to carry. Although some vehicle frames can be folded to be slightly smaller, it has too many folding joints. The folding speed is very slow and other disadvantages, but since there is no vibration damping device installed, the vibration generated during riding is mainly reduced and absorbed by the fully inflated tires and the spring under the seat. The vibration is still relatively large for people and the entire frame, so that the vibration generated by long-term riding will cause loosening and damage to the frame itself, and sometimes cause danger to the rider due to the loosening and damage of vehicle parts
