Flat folding mechanism for front and rear wheel sets of baby stroller

Abstract

The invention discloses a flat folding mechanism for front and rear wheel sets of a stroller, which comprises a foldable skeleton, a front wheel set, a pair of rear wheel sets and a driving assembly. Wherein the pair of rear wheel sets can be horizontally pivotally sleeved on the bottom of the rear end of the collapsible frame, and the drive assembly is linked between each rear wheel set and the collapsible frame, and the collapsible frame self-expands The rotation of the folded to the folded state interlocks the pair of rear wheel sets, so that each rear wheel set turns from the angle of longitudinal rolling forward to the angle of deflection of 90 degrees at the same time. The flattening and folding mechanism of the front and rear wheel sets of the stroller of the present invention can make the two rear wheel sets rotate 90 degrees at the same time when the stroller pivots from the expanded state in use to the folded state, and are roughly flat and side by side on the same plane. The plane can indeed achieve the function and purpose of flattening the folding of the baby carriage and reducing the packaging volume and storage and transportation space.

Description

technical field [0001] The invention relates to a flattening folding mechanism for front and rear wheel sets of a baby carriage, in particular to a folding mechanism capable of flattening the baby carriage and reducing packaging volume and storage and transportation space. Background technique [0002] The stroller is a means of transportation specially designed for infants. In order to minimize the packaging volume for storage and transportation, it must be locked in the unfolded state during use, and can be folded during storage and transportation to minimize the size. [0003] However, the rear wheels of traditional baby carriages are all fixed in the direction of rolling forward. Unless they are removed in advance, after the baby carriage is folded, the wheel diameter of the rear wheels will cause a basic obstacle that is difficult to reduce the volume of storage and transportation. There is room for further improvement. Contents of the invention [0004] In order to ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned problem that the volume cannot be further reduced, the object of the present invention is to provide a flattened folding mechanism for the front and rear wheel sets of the baby carriage that can flatten the foldable stroller and reduce the packaging volume and storage and transportation space.
