Quick folding structure for electric bicycle or bicycle

Abstract

The invention discloses a quick folding structure for an electric bicycle or a bicycle. A self-locking connecting rod is arranged, the upper end of the self-locking connecting rod is hinged to and linked with the rear end of a first front connecting rod, and the lower end of the self-locking connecting rod is hinged to and linked with the front end of a rear frame. When the upper end link joint of the self-locking connecting rod moves to the rear side of a motion borderline, the folding structure is folded and locked; when the upper end link joint of the self-locking connecting rod moves to the front side of the motion borderline, the folding structure is unlocked and unfolded. The self-locking connecting rod is connected with the first front connecting rod and the rear frame and plays a role in linkage, it is guaranteed that the first front connecting rod and the rear frame can move simultaneously when unfolding or folding operation is carried out, a bicycle body cannot be automatically opened because of the angle self-locking function of the self-locking connecting rod under the folding state, and the electric bicycle or the bicycle can be folded as long as a connecting plate is lifted. The quick folding structure has the advantages of being simple in folding process, high in folding speed and convenient to use.

Description

technical field [0001] The invention relates to the technical field of foldable electric vehicles or bicycles, in particular to a fast folding structure for electric vehicles or bicycles. Background technique [0002] Traditional electric vehicles or bicycles cannot be folded, and take up a large space when stored. The foldable electric vehicles or bicycles disclosed in the prior art have the disadvantages of cumbersome folding process and slow folding speed, and often require multi-step operations to be able to move the electric bicycle. The car or bicycle is adjusted from the unfolded state to the folded state, which is inconvenient for users to use. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a fast folding structure for electric vehicles or bicycles to achieve the purpose of simplifying the folding process of folding electric vehicles or bicycles, increasing the folding speed, and making folding elec...
