Abstract

The invention discloses a wide-angle reversing baby carriage base which is formed by mechanically linking a horizontal reversing assembly and a vertical reversing assembly. The horizontal reversing assembly comprises a seat body, a rotating shaft shell and a limiting assembly with a spring inserted rod, and the vertical reversing assembly comprises a bearing seat, a bottom plate and a wheel carrier assembly with an elastic clamping column. The rotating shaft shell is driven to rotate by turning over the same handlebar, the pressing part on the rotating shaft shell pushes the inserted rod to be inserted into the clamping hole of the bottom plate to realize horizontal limiting, and meanwhile, the pushing part pushes the pushing piece to be matched with the elastic clamping column in the wheel carrier joint, so that vertical hinging is locked. The design realizes bidirectional linkage reversing in the horizontal and vertical directions, has the advantages of simple operation, quick response, compact structure, stable locking and the like, and effectively improves the reversing consistency and user experience of the baby carrier.
