STROLLER
Document Type and Number:
WIPO Patent Application WO/2023/155462
Kind Code:
A1
Abstract:
A stroller, comprising a stroller frame (1), which has an unfolding position and a folding position, and a plurality of wheel assemblies, which are disposed at the bottom of the stroller frame (1). The stroller frame (1) comprises a base (10), bottom wheel frames (11) that are sleeved on the base (10) and can use their own center lines as flipping axes (X4), and connecting rods (12) that are disposed on the base (10) in a manner of rotating about a first folding axis (X1). The central line of the first folding axis (X1) is spatially perpendicular to the central lines of the flipping axes (X4). The connecting rods (12) are each provided with a connecting rod swing section (121) thereon. The bottom wheel frames (11) are each provided with a fixed upper limiting portion (11a) and a fixed lower limiting portion (11b) thereon. The connecting rod swing section (121) is located between the upper limiting portion (11a) and the lower limiting portion (11b). When the stroller frame (1) is folded or unfolded, the connecting rod swing section (121) abuts against the upper limiting portion (11a) or the lower limiting portion (11b) to drive the bottom wheel frames (11) to rotate relative to the base (10), such that the effects of the wheel assemblies synchronously extending downwards when the stroller frame (1) is unfolded and synchronously retracting upwards when the stroller frame (1) is folded are achieved.
