Folded pedal for folded bicycle

Abstract

The invention discloses a folded pedal for a folded bicycle, and relates to a technology for a structure of a folded pedal for a folded bicycle. The folded pedal mainly comprises a crank base, a crank, a pawl, a pawl returning spring, a series drive cam and a returning spring, wherein the crank is hinged to the crank base; the pawl is hinged to the crank base and is meshed with a corresponding ratchet on the crank; the series drive cam is hinged to the crank base; a cam higher pair is arranged between the series drive cam and the pawl and the crank; the series drive cam sequentially drives the pawl to separate from the crank and drives the crank to be rotationally folded under the action of external force; the external force is from a drive ring sleeved on a center shaft seat; the drive ring is controlled by a folding control mechanism; when the folded pedal is unfolded, the pawl is meshed with the ratchet on the crank, the crank is relatively fixed with the crank base, and the drive ring is separated from the series drive cam; when the pedal is folded, the drive ring pushes the series drive cam outwards to drive the crank to be rotationally folded; and after the external force is cancelled, the returning spring drives the crank to be rotationally unfolded.

Description

technical field [0001] The invention relates to a vehicle, in particular to a folding pedal structure technology of a folding bicycle. Background technique [0002] As a non-polluting means of transportation, bicycles have been gradually recognized and valued by people in today's era of advocating green and low-carbon life, but their large size restricts its use, especially in public transportation systems. Those who are the main means of transportation and those who have experienced bicycle theft have a deep understanding. Although there are various folding bicycles for sale on the market, they are still relatively large in size after folding, and the folding operation is not very convenient. Contents of the invention [0003] The present invention provides a folding pedal with high folding rate and convenient folding operation, aiming at the fact that the existing folding bicycle is still large in volume after being folded and is inconvenient to fold, especially the peda...
