Abstract

The invention relates to a foldable bicycle and a manufacturing process thereof. The foldable bicycle comprises a front frame and a rear frame, the front frame is composed of a front fork pipe, a stem handle connected at the upper end of the front fork pipe, a front wheel connected with a fork end of the front fork pipe, and an L-shaped fixing bowl group pipe connected in the middle of the front fork pipe in a pivoted manner, the rear frame is composed of a rear fork pipe, a pipe cap connected at the upper end of the rear fork pipe, a rear wheel connected with a fork end of the rear fork pipe, and a seat rod connected in one of two supporting pipes in an inserted manner, a chain wheel power mechanism is arranged on the rear fork pipe which is connected with the supporting pipes, a folding mechanism is arranged between the L-shaped fixing bowl group pipe and the rear fork pipe and composed of an L-shaped sliding lift pipe which is mounted on the front fork pipe in a sleeved manner and positioned between a handlebar stem and the L-shaped fixing bowl group pipe, a front connecting pipe connected with a side pipe end of the L-shaped sliding lift pipe in a pivoted manner, and a double-row flat iron connecting rod connected with a side pipe end of the L-shaped fixing bowl group pipe in a pivoted manner, a position where the double-row flat iron connecting rod, the front connecting pipe and the pipe cap of the rear fork pipe are intersected forms a pivoted connection mechanism through a pivot, a free end head of the double-row flat iron connecting rod is connected with the seat rod in a contacting manner, and the foldable bicycle further comprises a self-locking mechanism after folding.

Description

technical field [0001] The invention relates to a folding bicycle and its manufacturing process. Background technique [0002] Currently commercially available folding bicycles have a slow folding speed and are bulky after being folded, making them inconvenient to carry. Contents of the invention [0003] The purpose of the present invention is to provide a folding bicycle with fast folding speed, small volume after folding 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 a front fork tube and a handle connected to the upper end of the front fork tube, a front wheel connected to the fork end of the front fork tube, and an L-shaped fixed bowl set pivotally connected to the middle of the front fork tube Tube, the folding mechanism pivotally connected with the front fork tube to form the front frame; it also incl...
