Foldable baby carriage and foldable electric baby carriage

Abstract

The invention discloses a foldable baby carriage. The foldable baby carriage comprises rear wheel support legs, hinge rods, two foldable side frames and a connecting rod for connecting the two foldable side frames, wherein a baby placing space is formed between the two foldable side frames; the foldable side frames comprise upper rods, lower rods, front rods and back rods; the upper rods, the back rods, the lower rods and the front rods are hinged in sequence to form square frames; one ends of the lower rods have bent parts; the tail ends of the bent parts are hinged to the middle parts of the back rods; the lower parts of the back rods are hinged with one ends of the hinge rods; the other ends of the hinge rods are hinged to the rear wheel support legs; and the upper parts of the rear wheel support legs are hinged to the middle parts of the upper rods. As the two foldable side frames synchronously fit tension springs for use, the foldable baby carriage can finish the folding and the unfolding more conveniently, more quickly and more stably, and parents can finish the folding and the unfolding of a carriage body by one hand; and the foldable baby carriage is specifically suitable for an electric baby carriage, and can save more labor in folding of the electric baby carriage with a higher weight.

Description

technical field [0001] The invention relates to a baby carriage, in particular to a folding baby carriage and a folding electric baby carriage. Background technique [0002] At present, there are mainly three folding methods for baby strollers: umbrella folding (width compression), joint folding (height and length compression), and extreme shrinkage folding according to its own structural characteristics. [0003] Because of this new folding structure, it is aimed at a kind of electric stroller with a fixed rear axle, so it adopts a fit folding that cannot compress the width. [0004] The combined folding mechanism on the market can also be divided into two types. One is the traditional and simple folding combined with the parallelogram principle. This type of mechanism has two defects: [0005] 1. Since the structural parts cannot complement each other in shape after folding, the volume cannot be compressed to the minimum after fully folding; [0006] 2. Since there is no...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the structural parts cannot complement each other in shape after folding, the volume cannot be compressed to the minimum after fully folding;

[0006] 2. Since there is no additional power assistance, it requires the coordinated operation of both hands and even feet

For parents who often need to hold their children in one hand, it is difficult to complete the folding outdoors alone

[0007] Another type of folding is a composite mechanical structure with interaction, which can automatically complete the contraction and expansion at one time with a single button. The disadvantage of this mechanism is that there are many adapters and telescopic parts, resulting in structural stability and reliability. reduction and increase in weight and cost
