Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0048] see figure 1 Shown is a schematic diagram of the vehicle components. It includes a front frame assembly 1 and a rear frame assembly 2. The front vehicle frame assembly 1 is made up of front fork tube 11 and front wheel 12, fixed bowl tube 13, pull tube 14, handlebar 15, pivot joint tube 16, lower link 17 socket or pivot connection. Rear vehicle frame assembly 2 is made up of seat post 21, rear fork tube 22, pipe cap 23, rear wheel 24, seat tube 25, positioning plate 26, chainring shaft 27. The front and rear vehicle frames are pivotally connected with the pipe cap 23 through the pivot pipe 16 .

[0049] see figure 2 Shown is a schematic diagram of component alignment. The upper six ports 131 and the lower six ports 141 are hexagonally socketed to make the mechanism more stable. The shaft holes 130 / 170, 140 / 160, and 164 / 171 are pivotally connected, and...

Abstract

The invention relates to a folding bicycle and a manufacturing process thereof. The folding bicycle comprises a front fork pipe, a handlebar disc, a front wheel and a folding mechanism which form a front bicycle frame, wherein the handlebar disc and the front wheel are connected with the two ends of the front fork pipe, and the middle of the front fork pipe is sleeved with the folding mechanism. The folding bicycle further comprises a rear fork pipe, a pipe cap, a rear wheel, a positioning plate, a seat pipe and a crankset shaft which form a rear bicycle frame, wherein the pipe cap and the rear wheel are connected with the two ends of the rear fork pipe, and the positioning plate and the seat pipe are welded to the middle of the rear fork pipe. The rear fork pipe is pivotally connected with the folding mechanism to enable the front bicycle frame and the rear bicycle frame to form the whole bicycle. The folding bicycle is characterized in that during folding, the rear bicycle frame can rotate by 90 degrees, the two wheels are axially folded, and the folding bicycle can be pulled to travel after two shaft heads are inserted and positioned; during semi-folding, a seat rod and the oval handlebar disc are bolted into an inclined strut shape and mounted on a fork shoulder to form a seat, and universal wheels are mounted under a stool to form a trolley; and during unfolding, the rear bicycle frame is rotated back by 90 degrees to enable the front bicycle frame and the rear bicycle frame to form a ridable stable state. The most important characteristics of the folding bicycle are that folding and unfolding are brisk, and functions are practical.

Description

technical field [0001] The invention relates to a folding bicycle and its manufacturing process. Background technique [0002] Currently commercially available folding bicycles have slow folding speed, single function and are not easy to carry. Contents of the invention [0003] The purpose of the present invention is to provide a foldable bicycle that can be ridden, folded quickly, half-folded into a seat or a stroller, and easy to carry. Another object of the present invention is to provide a manufacturing process of a folding bicycle. [0004] The technical solution of the present invention is that the folding bicycle includes the front fork tube and the front fork tube connected to the front fork tube and the front wheel, and the folding mechanism in the middle of the front fork tube to form a front frame; it also includes the rear fork tube And the caps connected to the two ends of the rear fork tube and the rear wheel, the positioning plate welded in the middle of ...
