AI Technical Summary
Existing strollers are too long when folded, making them difficult to fit in small spaces such as the trunk of a compact car or the overhead bins of an airplane. Furthermore, traditional folding methods take up a lot of space, affecting portability.
Employing a multi-port adapter and angle adjustment structure, the eccentric rod is driven by rotating the multi-port adapter, which in turn drives the folding linkage. Combined with the angle adjustment structure, the stroller can be folded quickly and compactly, shortening its longitudinal length. The angle of components such as the push handle and sunshade can be adjusted to adapt to different usage scenarios.
It enables convenient storage of children's strollers in small spaces, shortens the folded length by about 50%, and is easy to operate, folding it in ten seconds with one hand, improving portability and user comfort.

[0002] The mainstream child's cart currently adopts the one-time folding mode of horizontal overall compression, that is, the components such as frame and seat are synchronously folded along the horizontal direction by linkage mechanism. Although this folding mode can realize the volume reduction to a certain extent, the longitudinal length of the cart after folding is still relatively long, and the structure is loose. For example, when the cart needs to be placed in the trunk of a compact car or the luggage compartment of an airplane or other space-limited scenarios, the relatively long longitudinal size often leads to unsuccessful placement or repeated angle adjustment and compression, which not only wastes time but also may damage the cart components. In addition, in the standing area of public transportation (such as subway and bus) or the narrow aisle of a small family house, the traditional folded cart still occupies a lot of space, which is not conducive to carrying and passing. With the acceleration of urban life rhythm and the diversification of family travel needs, consumers have higher requirements for the "extreme portability" of child's carts.
