[0002] With the continuous development of modern science and technology, artificial intelligence and intelligent design have been widely used in the field of children's products. In this context, multifunctional baby strollers have emerged. They not only provide basic baby travel functions, but also integrate a variety of intelligent and convenient features to meet the needs of modern families. These vehicles usually have multiple functions such as lightweight high-view, 360-degree rotation, and flat lying to meet the use needs of children of different ages. In addition, the design research of multifunctional smart baby strollers also shows that the intelligent design of baby strollers can be reformed and innovated in combination with technological trends to make them market-rational and user-demanding.

[0003] The multifunctional strollers currently on the market have been designed with considerations of ergonomics, material science, mechanical design, electronic technology, user experience and other fields in mind. These strollers usually have the following features: adjustable seat height, backrest angle and armrest height to suit the growth and development stages of different children; use of lightweight and high-strength materials such as carbon fiber and aluminum alloy to reduce weight and facilitate carrying and handling; integrated sensors and control systems to achieve functions such as automatic rocking, rotating seats, and smart brakes; design of human-computer interaction interfaces such as touch screens or voice control so that parents can easily control the various functions of the stroller. In addition, some strollers also have power-assisted systems, which are suitable for use when older parents are looking after babies, or for power-assisted use when taking babies for morning jogging, sports, mountain climbing and other activities.

[0004] Although the existing multifunctional baby strollers have been designed with many convenience and comfort factors in mind, there are still some technical problems when equipping educational institutions with baby balance strollers. Traditional balance strollers usually use bolts and other parts to adjust the height of the seat and handlebars.
