Abstract
A baby carriage is disclosed. Its carriage frame (1) comprises a first front wheel bracket (11), a first push rod (12) with the lower end rotatablely connected to the upper portion of the first front wheel bracket (11), a first seat rod (13) with the front portion rotatablely connected to the first front wheel bracket (11), a second front wheel bracket (21), a second push rod (22) with the lower end rotatablely connected to the upper portion of the second front wheel bracket (21), a second seat rod (23) with the front portion rotatablely connected to the second front wheel bracket (21), a back supporting frame (40) composed of a first back rod (41) and a second back bottom rod (42) that intersect and rotatablely connect with each other at the intersection joint, and a bottom supporting frame (30) composed of a first bottom rod (31) and a second bottom rod (32) that intersect and rotatablely connect with each other at the intersection joint. The upper end of the first back rod (41) is rotatablely arranged to the first push rod (12), and the upper end of the second back rod (42) is rotatablely arranged to the second push rod (22). The back portion of the first seat rod (13) is rotatablely connected to the second back rod (42), and the back portion of the second seat rod (23) is rotatablely connected to the first back rod (41). The bottom supporting frame (30) is disposed between the two front wheel brackets (11, 21) and the two seat rods (13, 23). The back end of the first bottom rod (31) is rotatablely connected to the back portion of second seat rod (23) through a fourth rotational joint (36), and the back end of the second bottom rod (32) is rotatablely connected to the back portion of the first seat rod (13) through a third rotational joint (35). The back portion of the first seat rod (13) is rotatablely connected to the second back rod (42) through a seventh rotational joint (45), and the back portion of the second seat rod (23) is rotatablely connected to the first back rod (41) through a eighth rotational joint (46). It is noted that the fewer rods of the carriage frame significantly reduce the production cost.
