High-intensity folding vehicle head component

Abstract

The invention discloses a high-intensity folding vehicle head component which comprises a vertical pipe, a front fork, a frame head pipe and a cross pipe integrally welded with the frame head pipe, wherein a joint place between the vertical pipe and the frame head pipe is further provided with a vertical pipe folder, the vertical pipe folder comprises an upper joint and a lower joint, the upper joint is integrally welded with a lower-end pipe opening of the vertical pipe, the lower joint is locked at the upper-end pipe opening of the frame head pipe by a fixed component, the fixed component comprises a long-diameter bolt, a spring washer, a metal washer and a positioning pipe, an inclined fixed block is fixed in the front fork, a threaded hole is arranged in the inclined fixed block, and an outer ring of the lower joint downwards extends to form into an outer lantern ring. According to the high-intensity folding vehicle head component, the connection structure mode and somepart of structure shapes in the vehicle head component are improved, so that the whole connection strength of the high-intensity folding vehicle head component can be improved, the service life of the vehicle head component can be greatly prolonged, and the folding mode is simpler and more reliable, so that the folding size is more compact, and the safety and the usability can be greatly improved.

Description

technical field [0001] The invention relates to the field of vehicle parts, in particular to a high-strength folding vehicle head assembly. Background technique [0002] The frame component is the basic structure that constitutes the bicycle, and it is also the skeleton and main body of the bicycle. Other components are also directly or indirectly installed on the frame. The front fork part is in the front position in the bicycle structure, its upper end is connected with the handlebar part, the vehicle frame part is matched with the front tube, and the lower end is matched with the front axle part to form the guiding system of the bicycle. Turning the handlebar and front fork can change the direction of the front wheel and play a guiding role in the bicycle. In addition, it can also play a role in controlling the running of the bicycle. The stress of the front fork is in the nature of a cantilever beam, so the front fork must have sufficient strength and other properties. ...

AI Technical Summary

Problems solved by technology

[0003] The folding and fixing devices in the front fork parts of the prior art are generally exposed outside, and are directly fixed by lock nuts, and the fixing method is not strong enough, which easily leads to deformation of the front of the car

At the same time, the structure of the joints of existing bicycles is complex, the strength and rigidity are not enough, and the folding effect is not good.
