[0002] Strollers play a vital role in daily life as an essential tool for infants and toddlers. With rapid societal development and increasing family travel demands, parents are placing higher demands on the convenience, comfort, and safety of strollers. Portability has become a key factor for modern families when purchasing strollers. To adapt to the fast pace of urban life, modern strollers not only need a sturdy structure and a comfortable riding experience, but also need to be easy to store and carry to meet the needs of families in different scenarios. For example, the size of a stroller directly affects its ease of use when traveling, using public transportation, or simply storing it. Therefore, a compact and portable folding stroller has become an important direction for market development.

[0003] Most traditional children's strollers on the market today use a fixed frame structure, mainly composed of components such as the frame, wheels, seat, and sunshade.
