Description

Bidirectional baby stroller

Technical Field

The invention belongs to the technical field of baby strollers, and particularly relates to a bidirectional baby stroller.

Background

The baby carriage is a tool carriage designed for providing convenience for outdoor activities of babies, and has various vehicle types, the baby carriage is generally played by children aged 1 to 2 years, the toy carriage with wheels is played by children aged over 2 years, the baby carriage can bring certain benefits to the intelligence development of the children, and the brain development of the children is increased.

The baby carriage is a favorite walking vehicle for babies, and is an essential product for mothers to take babies to shop on the street. However, the baby carriage can be divided into various types according to the growth and usage of the baby. Mainly according to the standard of the load capacity, and the general test standard is nine to fifteen kilograms. A typical stroller can be used for about four to five years.

Generally speaking, the baby carriages of the asian market (of japan or taiwan) are divided into two major types, type a and type B. The A-type vehicle can be used after the head of the baby is supported after the baby is full of 2 months; the B-type vehicle can be used after the baby is seated stably for about 7 months. In any style, the product can be used for about 2 years old. The two vehicles are respectively of a long distance, the vehicle A is suitable for walking outside, and the vehicle B is suitable for riding an electric car or shopping outside. Wherein, the A-shaped baby carriage (i.e. the full-function baby carriage) can be laid in the baby carriage, the 175-degree lying is more suitable, which can not only prevent milk spitting, but also is beneficial to the growth and development of bones, and even if the baby falls asleep, the baby does not need to worry about. Because the wheels are large and have the function of shock absorption, the jolt caused by the uneven ground is less, so that the baby feels very safe when sitting and the brain development of the baby is facilitated. If the direction of the handle can be switched, the baby can be seen to go out to walk; if the automobile body is provided with the air filter cover, the automobile can also go out in rainy days or haze days. However, such vehicles are heavy and take up a lot of space. The B-type baby carriage (i.e. the portable folding baby carriage) is small and portable, the handle is simple to control, and the turning is convenient. Can be used for shopping in shops with narrow passage or for shuttling at crowded places. The folding cart can be seated and laid, does not occupy space even in an electric car after being folded, and can be placed in a car trunk or a trunk to be used when going out of a door. Compared with the A-type vehicle, the seat is slightly narrower, and the adjustable angle is smaller. The baby carriage is unidirectional in direction, cannot change the orientation of a child, can only look forward, and is single in function. There are also baby carriages with 360 ° rotation seats, which are relatively rare on the market, and which, apart from being able to lie flat, have a unique 360 ° rotation of the seat and do not require lifting of the seat. The baby can look forward at the 0-degree direction, and can look at scenery at two sides of the road at 90-degree and 270-degree directions without looking at the heels of adults and smelling automobile tail gas, and the front side faces to the mother at 180-degree direction. Although the orientation of the child can be changed by rotating the seat, the structure is complicated and the operation is inconvenient.
