Embodiment Construction

[0026] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right", "inner", "outer" and similar expressions are used in this specification for the purpose of description only.

[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. Terms used in the description of the pre...

Abstract

The embodiment of the invention relates to the technical field of folding bicycles, and discloses a folder. The folder comprises a first folding part, a second folding part and a locking part, whereinthe first folding part is provided with a first connecting part; the second folding part is provided with a second connecting part, and the second connecting part is rotationally connected with the first connecting part, and is provided with a first annular tooth; the locking part comprises a matching assembly and a control assembly, the matching assembly is provided with second annular teeth matched with the second connecting part, the control assembly is connected with the matching assembly, is used for controlling the first annular tooth to be engaged with the second annular teeth and controlling the matching assembly to be fixed to the first connecting part in a first state so that the second folding part can be fixed to the first folding part, and is used for controlling the first annular tooth to be separated from the second annular teeth and controlling the matching assembly and the first connecting part to be separated from fixation in a second state so that the second foldingpart can rotate relative to the first folding part. Occurrence of the phenomenon that due to overlarge force, a hinging shaft is loosened is avoided.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of folding bicycles, in particular to a folder. Background technique [0002] Folders are commonly used in the field of folding bicycles, folding electric vehicles, or folding scooters. In order to reduce the volume of the folded vehicle, it is a common way to fold the girder, frame, etc. through the folder. [0003] One end of the existing folder joint is connected by a hinge shaft, and the other end is fixed by a clamping block. Usually the upper and lower joints are connected to the hinge shaft with relatively small apertures. If too much force is applied, the hinge shaft may become loose. [0004] In the process of realizing the present invention, the inventors found that the prior art has at least the following problems: the hinge shaft may become loose during high-strength use, and the locking position of the clamping block is easily deformed. Contents of the invention [0005]...
