Description

Bolt type folding mechanism and scooter

Technical Field

The application relates to the technical field of folding devices, in particular to a plug pin type folding mechanism and a scooter.

Background

Scooter generally comprises a transverse handle assembly (hereinafter referred to as a handle), a vertical pipe assembly (hereinafter referred to as a vertical pipe), a front fork assembly (hereinafter referred to as a front fork), a front wheel assembly, a frame (including a head pipe) assembly, a rear fork assembly and a rear wheel assembly, wherein the common setting positions of the folding mechanism are between the front fork and the vertical pipe and between the head pipe and the frame.

The folding mechanism arranged between the front fork and the vertical pipe in the market at present is generally realized by adopting a combination of a triangle structure and a cam, mainly applying the principle of triangle geometric stability (the front fork and the vertical pipe are connected through a shaft to form a triangle vertex A with a rotation center, the cam and the front fork are connected through a shaft to form a triangle vertex B with a rotation center, the cam and the vertical pipe are connected through a buckle to form a triangle vertex C with a opening point of the front fork and the vertical pipe, and the cam is used for compensating the manufacturing tolerance of parts. When the scooter stand pipe is in an open state (i.e. a state capable of riding), the folding mechanism is closed (mainly connecting the front fork and the stand pipe in a buckle mode), the cam is manually locked, and the stand pipe, the front fork and the folding mechanism form a triangular stable structure. When the scooter stand pipe is required to be switched to a folding state (namely a state capable of being stored or carried), the cam is manually unlocked, the folding mechanism is opened (the buckle is disengaged), and the stand pipe and the front fork are connected only through the rotating shaft.

The present inventors found that there are at least the following technical problems in the prior art:

1. when the riser is in an open state, the user sometimes forgets to manually lock the cam, resulting in the locking function being disabled. The stand pipe and the front fork have risks of shaking, disengaging, breaking and the like in the riding process, and if the stand pipe and the front fork are disengaged or broken, the situation of falling people can be caused.

2. Because the parts forming the folding mechanism are all made of steel, the cam is mainly used for compensating the gap generated after assembly caused by manufacturing errors, and finally locking is realized to avoid the problem of shaking in the riding process. The cam can generate tiny deformation under the locking state, so that interference fit is achieved, a certain external force is needed for locking, and otherwise, the locking cannot be achieved.

3. When the vertical pipe is in an open state, the vertical pipe is realized by means of buckling, end face lamination of the vertical pipe and a front fork and cam locking combination, and when the vertical pipe is used for a long time or is assembled for the first time on a product line, the tightness degree of the mechanism needs to be manually adjusted, so that the requirement on quality control of products is high.
