Baby carriage

Abstract

The invention discloses a baby carriage. The baby carriage comprises two side frames and transverse levers, wherein each of the side frames comprises a front foot lever, a rear foot lever and a push lever; the push lever comprises a push lever handgrip, an upper push lever, a middle push lever and a lower push lever, wherein the upper push lever is arranged in the middle push lever in an inserting manner to realize locking or expanding or contracting, and the middle push lever and the lower push lever can be locked or folded when being hinged; each of the front foot levers is divided into an upper front foot lever and a lower front foot lever, a front support lever and a rear support lever are connected between each of the upper front foot levers and the corresponding lower push lever, and a foldable first four-connecting-lever mechanism is formed; the upper front foot lever and the rear foot lever are sequentially connected with a first connecting lever and a second connecting lever, and a second four-connecting-lever mechanism is formed; one end of each of the first connecting levers and the lower end of the corresponding front support lever are fixedly connected or integrally formed; and each first four-connecting-lever mechanism in a foldable state is overlaid on the upper side of the corresponding upper front foot lever, and each rear foot lever is overlaid on the lower side of the corresponding upper front foot lever. The baby carriage adopting the technical scheme is reasonable in structure, small in size after being folded and convenient and effortless to operate.

Description

technical field [0001] The invention relates to the technical field of strollers for children, in particular to a foldable stroller for children. Background technique [0002] Stroller is a tool cart designed for the convenience of baby's outdoor activities. It is the baby's favorite means of transportation for walking, and it is also a must-have for mothers when they take their baby to the street for shopping. With the progress of production and life, there are more and more usage scenarios of baby carriages. [0003] The Chinese patent document with publication number CN101544242 discloses a foldable stroller, which belongs to the technical field of folding mechanism structure. A foldable stroller, comprising a push rod and a front wheel bracket and a rear wheel bracket with wheels at the bottom, characterized in that the front wheel bracket and the rear wheel bracket are movably connected to the upper push rod through a center plate, and the middle part of the push rod i...

Problems solved by technology

This technical solution still has the following problems: 1. When unfolding, the front frame, the side rod and the push rod frame are unfolded into a straight line, and the locking mechanism locks the car body by squeezing the push rod frame and the side rod. It is necessary to push the push rod frame to rotate to form a lever to fold, which is not only inconvenient to fold, but also requires a lot of force, and the force is concentrated, which is easy to damage the push rod frame; 2. The push rod frame adopts two-stage telescopic, and the length is still long Long, the front frame cannot be folded and the length is too long, so that the frame is still bulky after being folded; 3. If you need to fold the rear wheels together to make the frame smaller, you need to squat down first and then fold it After the rear wheels are put away by the frame, the two side supports are then folded. The operation is inconvenient, the process is unreasonable, and the requirements for the use skills are too high; , it is inconvenient to collect and use; 5. The locking mechanism and multiple joint mechanisms are exposed, which is easy to cause harm to children and affect the safety of use

This solution adopts the chassis seat structure. In order to ensure the stability of the frame, the chassis seat is bulky and cannot be folded, so that the folded frame is still large in size, although it also shows that the push rod can be retracted or folded. Yes, a simple bending structure is also given, but even after the push rod is bent, the frame volume is still large
