Document Type and Number:
WIPO Patent Application WO/2024/087310
Kind Code:
A1
Abstract:
A stroller, comprising: an underframe (1), an upper enclosure frame (2), and a folding mechanism arranged between the underframe (1) and the upper enclosure frame (2) and used for driving the upper enclosure frame (2) to move closer to or away from the underframe (1). The folding mechanism comprises a first linkage assembly and a second linkage assembly. The first linkage assembly comprises a first upper link rod (61) and a first lower link rod (62), wherein the upper end of the first upper link rod (61) is rotatably connected to the upper enclosure frame (2), the lower end of the first lower link rod (62) is rotatably connected to the underframe (1), and the lower end of the first upper link rod (61) is rotatably connected to the upper end of the first lower link rod (62). The second linkage assembly comprises a second upper link rod (63) and a second lower link rod (64), wherein the upper end of the second upper link rod (63) is rotatably connected to the upper enclosure frame (2), the lower end of the second lower link rod (64) is rotatably connected to the underframe (1), and the lower end of the second upper link rod (63) is rotatably connected to the upper end of the second lower link rod (64). The first linkage assembly cooperates with the second linkage assembly, and when one of the first linkage assembly and the second linkage assembly moves, the other one is driven to move synchronously, such that the upper enclosure frame (2) performs a translational motion up and down relative to the underframe (1).
