Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings.

[0058] Such as Figures 1 to 18 A kind of folding bicycle shown comprises: headstock assembly 3, saddle assembly 2, front wheel assembly 1, rear wheel assembly 4 and the X-shaped center frame that can be combined in the middle.

[0059] 1. Front assembly 3:

[0060] The headstock assembly 3 includes a hollow headstock rod 31, a transmission rod 30, a three-way support 34 and an annular handrail 33 for holding or leaning on an elbow. Wherein: the upper end of the transmission rod 30 is fixed on the tee support 34, and the lower end of the transmission rod 30 extends into the hollow headstock rod 31; on the transmission rod 30.

[0061] Specifically, the upper end of the hollow headstock rod 31 is movably mounted on the transmission rod 30 near the three-way support 34 through the bearing, and the hollow headstock rod 31 is fixed on the outer ring of the bearing, so w...

Abstract

The invention discloses a high-strength folding bicycle. A hollow bicycle head rod, a rear wheel frame and a first shell are integrally formed. A first part is lengthened to be used for fixing a bicycle head assembly and a rear wheel assembly. A seat rod, a front wheel hollow front wheel sleeve rod and a second shell are integrally formed. A second part is lengthened to be used for fixing a front wheel assembly and a saddle assembly. After the parts are integrally formed, the connection among the first part, the second part and all the parts is firmer, and the connected parts are not prone to fracture. The structural strength of a bicycle frame is high, the bicycle is not prone to deformation or fracture on account of physical impact in the using process, and the connection firmness between the other assemblies and the middle bicycle frame of the bicycle can be effectively enhanced.

Description

technical field [0001] The invention relates to a vehicle, which is a high-strength folding bicycle. Background technique [0002] A bicycle, also known as a bicycle or bicycle, is usually a small land vehicle with two wheels. After a person rides on the car, it is powered by pedals, which is a green and environmentally friendly means of transportation. English bicycle. Among them, bi means two, and cycle means wheel, that is, a two-wheeled vehicle. In Mainland China, Taiwan, Singapore, it is usually called "bicycle" or "bicycle". There are many types of bicycles, including single bicycles, tandem bicycles and multi-person bicycles. [0003] As an environmentally friendly means of transportation, bicycles are used for transportation and travel; more and more people use bicycles as fitness equipment for cycling and exercising; cycling itself is also a competitive sport, including road cycling, mountain biking, Track cycling, stunt bike racing, etc. [0004] Folding bicy...
