The child car seat is used to adjust the car seat belt to a position suitable for the baby after the baby is raised. The baby can use the car seat belt to protect himself like an adult. Because the safety belt has been adjusted to an appropriate position, the vehicle safety belt can directly cushion the forward inertia of the baby and the child car seat when the car is in collision, and pull the baby back without rushing forward indefinitely. At this time, the protection principle of the child car seat is the same as that of an adult using the safety belt to protect himself. In addition, the materials inside the seat play a cushioning role to effectively reduce the impact of collision, so as to protect the safety of children and reduce the casualty rate.
The principle of adjustable children's chair is that the lifting of the chair is mainly realized by the lifting device at the lower part of the chair surface. The current lifting devices are mainly divided into three categories: oil pressure, mechanical type and air pressure. Pneumatic lift is the most common lift. There is an air bar in the air pressure lift chair. The air bar is an elastic element that uses gas and liquid as working medium and can support, buffer, brake, height adjustment, angle adjustment, etc. Its basic principle is that the interior is filled with high-pressure nitrogen. Because there is a through hole in the piston, the gas pressures at both ends of the piston are equal, and the sectional areas at both sides of the piston are different, one end is connected with a piston rod and the other end is not, Under the action of gas pressure, pressure will be generated to the side with small sectional area, that is, the elasticity of the air bar. When people sit up to pressure the lifting shaft, the lifting shaft will fall gently, at an even speed, and can drop to the lowest point. No external force is applied to the lifting shaft, and the lifting shaft is lifted back to the highest point. Normal manufacturers use nitrogen to fill, the concentration is generally above 99%, and the pressure is about one or two atmospheres.
