A folding method of a foldable bicycle saddle

Abstract

The invention relates to an automatic folding method of a folding type bicycle saddle seat. The automation means that the folding action is finished under the non-contact state of the hand and the saddle seat or a saddle pipe; the folding means that the saddle seat is shrunk to a set position under the folding state, is restored automatically to a preset height in unfolding and the preset height can be adjusted randomly; the principle is as follows: a pull rope mechanism and a pin expanding and retracting sleeve mechanism are matched to control the folding of the saddle seat; the pin expanding and retracting sleeve mechanism mainly comprises a fixed pipe, an expanding and retracting pipe, an expanding and retracting pipe resetting spring, a pin and a pin resetting spring; the fixed pipe is provided with a plurality of positioning holes; the expanding and retracting pipe is provided with one or a pair of positioning hole(s) corresponding to the positioning holes on the fixed pipe; the saddle seat is fixedly connected on the expanding and retracting pipe; the pin penetrates through the corresponding holes of the expanding and retracting pipe and the fixed pipe to lock the mutual positions; in folding, the locked state of the pin is eliminated by a pull rope, and simultaneously the pull rope pulls the expanding and retracting pipe to the set position; and in unfolding, the pull rope is released and the expanding and retracting pipe resetting spring pushes the saddle seat to a preset height.

Description

[0001] The invention relates to a vehicle, in particular to a method for folding a foldable bicycle saddle. 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 still have a large volume after folding, especially the folding operation of the saddle is very inconvenient. . Contents of the invention [0003] The present invention provides a method for folding a saddle, aiming at the fact that the volume of the existing foldable bicycle is large after folding and the folding is inconvenient, especially the folding of the saddle is inconvenient. [0004] The basic idea o...
