Baby carriages

Abstract

The invention provides a baby carriage, belonging to the field technology of the baby carriage. The baby carriage is provided with an anti-squeeze turning structure, an obliquity adjustable operating mechanism, a four wheel earth-clawing structure and a middle rotating shaft. The invention ensures that squeezing and cutting can not be produced by an exposed structure for simple structure. The baby carriage which is characterized in that the obliquity of an operating arm can be adjusted, the earth-clawing capability of four legs is stable, and the front driving as well as the back driving are smooth not only meets the requirement of safety standards of international toy but also reduces manufacture cost.

Description

technical field [0001] The invention belongs to the technical field of children's vehicles, and in particular relates to a four-wheeled children's vehicle such as a kart. Background technique [0002] Karting is a transliteration of English Karting, which means a miniature sports car, which originated in the United States in the late 1950s. The structure of the kart is extremely simple: a frame, a two-stroke engine, and four independent wheels constitute the whole of the kart. Because karting is easy to drive, safe and exciting, it quickly became popular all over the world. It is called "karaoke" in motorsports. People of all ages can drive karting regardless of whether they know how to drive a car. Japan's Yamaha company has also specially designed a K30 kart for children, and children as young as 7 years old can drive it. [0003] Due to the influence of go-karts, various pedal go-karts and toy go-karts have emerged as the times require, and have become leisure and game ...

AI Technical Summary

Problems solved by technology

[0005] (1) The mechanical structure of the exposed structure has a large safety hazard, and the angle between some rods is easy to pinch children. During the steering process, the steering of the four-wheel stroller needs to realize the synchronous parallel steering of the front wheels, and the connecting rod structure is generally used , but the connecting rod structure is very easy to produce the angle between the rods when turning, which is easy to pinch and shear, which will cause harm to children's safety

Therefore, the shielding method is often used to close the unsafe structure when realizing the parallel steering of the front wheels. However, because the front wheels and related components cannot be completely closed, the shielding effect is not good, which not only increases the cost, but also still has accessible unsafe structures. structure

[0006] (2) Adapt to different objects of use with various specifications. The saddle seat (that is, the distance from the saddle seat to the pedal mechanism) of some products can be adjusted, but the inclination angle of the operating mechanism is generally not adjustable;

[0007] (3) Ordinary four-wheel heavy vehicles can only be used on flat ground, and it is rarely considered to set up a four-wheel grip mechanism suitable for different site conditions;

[0008] (4) In the functional design of the four-wheeled children's car, the driving function and the braking function are considered separately, and the ready-made driving parts and braking parts are used. There are many components and the structure is relatively complicated, and the setting is not considered to realize braking and front and back at the same time.
