Description

Bidirectional baby stroller

Technical Field

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

Background

The baby carriage is a tool carriage designed for facilitating outdoor activities of babies, and has various vehicle types, and generally, the baby carriage is played by children of 1 to 2 years old, and the toy carriage with wheels is played by children of 2 years old, so that the baby carriage brings 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 a necessary product for the babies to shop on the street. However, the strollers are classified into various types according to the growth and use of babies. Mainly according to the load capacity as standard, and the general test standard is nine to fifteen kilograms. Typical strollers are available for about four to five years.

In general, strollers in asian markets (japan or taiwan) are divided into two major categories, type a and type B. The A-shaped vehicle can be used after the baby is full for 2 months, and the head can be supported; the B-type vehicle can be used after the baby is full for about 7 months and can be stably seated. Whichever style is available, it is about 2 years old. The two vehicles are all good, the A-type vehicle is suitable for walking, and the B-type vehicle is suitable for riding an electric car or shopping. Wherein, the A-type baby carriage (namely the full-function baby carriage) can be used for lying in the carriage, and the baby can lie in the carriage at 175 degrees, so that the baby can not only prevent milk from spitting, but also be beneficial to bone growth and development, and the baby does not need to worry about sleeping. Because the wheels are larger and have the function of shock absorption, the bump caused by the rugged ground is less, the baby can feel very safe when sitting, and the brain development of the baby is facilitated. If the direction of the handle is switchable, the baby can also walk out of the face; if the automobile body is provided with the air filter cover, the automobile body can go out in rainy days or haze days. But such vehicles are relatively heavy and take up much space. The B-type baby carriage (namely the portable folding baby carriage) is small, exquisite and portable, and the handle is easy to control and convenient to turn. Can be bought in shops with narrow channels or shuttled back and forth in crowded places. The folding cart can be used for sitting and lying, does not occupy space even in an electric car after being folded, and can be placed in a trunk of an automobile or a suitcase, and a large dispatching place is used when going out. Compared with the type A vehicle, the seat is slightly narrower, and the adjustable angle is smaller. The directions of the baby carriage are unidirectional, the direction of the child cannot be changed, the baby carriage can only look forward, and the function is relatively single. There are also existing strollers with 360 ° rotatable seats, which are relatively rare in the market, and which are unique to 360 ° rotation of the seat, except for lying flat, and do not lift the seat. The baby is convenient to watch in different directions by positioning at four different angles of 0 degrees, 90 degrees, 180 degrees and 270 degrees, the baby can watch the scenery on two sides of the road in the directions of 90 degrees and 270 degrees forwards, the heel of a adult does not need to be watched and automobile exhaust is not smelled, and the direction of 180 degrees is opposite to the mother. Although the child's orientation can be changed by rotating the seat, the structure is complicated and the operation is inconvenient.
