The purpose of this utility model is to provide a kind of can transfer the Foldable baby carriage that the center of gravity of back car load is not moved after the meeting at backrest.

The technical solution of the utility model is: a kind of Foldable baby carriage, comprise vehicle frame, the pushing hands bar of forming by foreleg and back leg that is connected with described vehicle frame, front-wheel and the trailing wheel that is arranged at described vehicle frame below, and described vehicle frame is provided with back support bar; A be rotatably connected end of connecting rod of the bottom of described back support bar, the rear portion of the lower end of back support bar and seat board bar is rotatably connected, the other end and the vehicle frame of described connecting rod are rotatably connected, described seat board bar and vehicle frame sliding block joint, and described seat board bar is provided with seat cushion.

The utility model compared with prior art has following advantage:

When back support bar after falling, the seat board bar is subjected to the promotion of connecting rod to front slide, thereby makes seat cushion position reach, the seat board bar of its reach and the result of back support bar balance are that the center-of-gravity position of car load is constant.This being equilibrated at when transferring back support bar realized automatically, so processing ease.

The utility model will be further described below in conjunction with drawings and Examples:
