Baby carriage frame

Abstract

The invention discloses a baby carriage frame comprising a pair of carriage handles, a pair of front feet, a pair of rear feet, a pair of first connecting rods, a pair of second connecting rods and a pair of seat pipes. The two ends of each first connecting rod are connected with the lower end of the corresponding carriage handle and a corresponding front foot in a pivoted mode, the two ends of each second connecting rod are connected with the upper end of the corresponding front foot and the corresponding carriage handle in a pivoted mode, and accordingly a four-connecting-rod structure is formed. The upper end of one of the rear feet is connected with the upper end of the corresponding front foot in a pivoted mode, the two ends of each seat pipe is connected with the corresponding rear foot and the corresponding first connecting rod in a pivoted mode, and accordingly the other four-connecting-rod structure is formed. By means of the two four-connecting-rod structures, the whole baby carriage frame is driven to be transformed between an unfolding state and a folding state. Folding operation is smoother; the small size is achieved after folding; at the time of folding, single-hand actuating folding of the baby carriage frame can be achieved through folding operation parts arranged on the carriage handles, so that folding operation is easy and convenient; and the structure of the baby carriage frame is simple.

Description

technical field [0001] The invention relates to the technical field of baby carriages, in particular to a baby carriage with smoother folding operation and smaller volume after folding. Background technique [0002] With the widespread use of baby carriers, people have higher and higher functional requirements for baby carriers. It is hoped that the baby carrier not only makes the baby feel comfortable and safe when in use, but also hopes that it can be folded into a smaller body when not in use so as to achieve the effects of beauty, space saving and convenient storage. [0003] For example, the existing stroller frames generally have a folding function. When not in use, the frame body can be folded up, and the driver can also bend down to fit the front and rear legs, thereby saving space for storage. . But the existing baby carriage frame can be provided with a plurality of pivotal connection mechanisms in order to realize folding, and the design of these pivotal connect...

AI Technical Summary

Problems solved by technology

But the existing baby carriage frame can be provided with a plurality of pivotal connection mechanisms in order to realize folding, and the design of these pivotal connection mechanisms increases the complexity of the structure of the baby carriage on the one hand, and makes the folding of the baby carriage more difficult on the other hand. The operation is not easy and smooth enough

In addition, the stroller frame is generally in a long strip after folding, and the folded stroller frame does not have a positioning structure to position it, so that the stroller frame is easy to open during carrying and transportation, which is not conducive to carrying or transportation.
