Description

Technical Field

[0001] The utility model relates to the technical field of folding bicycles, in particular to a high-stability folding bicycle for infants. Background Art

[0002] A baby folding stroller, also known as a baby stroller or a baby carriage, is a means of transportation designed for babies, mainly to facilitate parents or guardians to take their babies out. A baby folding stroller provides a safe and comfortable riding environment for babies, allowing parents to take their babies to walk, shop or participate in social activities in fresh air outdoors. For babies, this is also an opportunity to exercise and promote development, while allowing babies to be exposed to various stimuli and new things in the outside world. Baby folding strollers often have the function of folding and storing, which greatly enhances their portability. Whether going to the park, shopping mall or traveling, parents can easily put the folded stroller into the trunk of the car or carry it in a handbag. Some advanced baby folding strollers also have multiple functions, such as awnings, storage baskets, adjustable handle heights, etc., which further enhance their use value and convenience.

[0003] In the existing baby folding strollers, when folding, most of them use the front legs as fixed legs, and fold the rear legs and the push rod part toward the front legs. However, under this design, the rear legs are in a flexible and flippable state, which makes the rear legs unstable. The overall stability of the baby stroller is more closely related to the stability of the rear legs. Therefore, the overall stability of the existing baby strollers needs to be improved.
