Description

[Technical Field]

[0001] This utility model relates to a children's stroller that can be folded up with one click. [Background Technology]

[0002] Strollers are mobile tools designed to facilitate the travel of infants, and they are becoming increasingly popular with parents. However, while strollers make travel convenient for infants, the portability of the stroller is also a major concern for parents. Most strollers on the market have a folding function, but traditional strollers are quite bulky when folded, and the folding operation is cumbersome. Not only do they need to be unlocked, but some also require both hands to operate, and some even require multiple people to complete the folding. This is very inconvenient for parents when traveling, especially when taking public transportation such as cars, buses, or subways. Furthermore, existing folding structures are complex, costly, cumbersome to assemble, and time-consuming to manufacture. [Utility Model Content]

No other operation is required. It is easy to operate, quick and convenient to fold up, has a simple structure, low cost, and saves time and effort in assembly.

[0018] This invention allows the stroller to be folded up and its overall size to be smaller than the carry-on size, making it easier to carry the folded stroller directly onto the plane without checking it in.

[0019] This invention allows the stroller to stand upright when folded. When folded, the rear wheels, front wheels, and the lower part of the handle extension rod are on the same horizontal plane, making the stroller stand stably without tilting or falling over.

[0020] When folding, the rotating rod drives the armrest assembly, which can slide backward. Since the connecting sleeve is rotatable, the armrest assembly can rotate while sliding, allowing it to retract into the entire folded size. Unlike existing strollers, the armrest assembly does not need to be disassembled, making it more convenient. [Attached Image Description]
