A kind of child intelligent seat and control method

Abstract

The invention discloses a child intelligent seat and a control method. The seat comprises a backrest, a base, pressure sensors, a weight sensor, angle regulating devices, a servo motor and a controller, wherein the pressure sensors are used for detecting pressure applied to the chair back by the human body, and the weight sensor is used for detecting the weight of the human body; each angle regulating device comprises an upper piece and a lower piece, one end of each upper piece is connected with the backrest, one end of each lower piece is connected with the base, an inner circular boss at the other end of each upper piece and an outer circular boss at the other end of each lower piece are in rotation connection, and the inner side of each angle regulating device is arranged at the joint of the base and the backrest; the center of each inner circular boss is provided with an inner gear; a rotating shaft of the servo motor is meshed with the corresponding inner gear so as to drive the corresponding upper piece to rotate, and the servo motor is arranged on the outer side of the corresponding upper piece; the controller is used for controlling the servo motor to be started and closed, and the controller is connected with a sensor set and the servo motor. According to the seat, the angle required to be regulated is judged according to the pressure and the height of children, and an angle regulating device is intelligently sensed and controlled to regulate the seat to be required angle.

Description

technical field [0001] The invention relates to a child seat. More specifically, the present invention relates to an intelligent child seat and a method for controlling the adjustment angle of the seat. Background technique [0002] At present, the penetration rate of private cars is very high. Most parents use cars to take their children to and from school, but many parents mistakenly believe that it is the safest way to hold their children in their arms and sit in the passenger seat. Such behavior often underestimates vehicle collisions When the speed of the vehicle reaches 50km / h (common speed for driving in the city), a child with a body weight of 40kg is equivalent to a 1-ton moving object. And the momentum generated by the child in a high-speed impact is equivalent to the weight of an elephant. Hugging the child at this time is equivalent to using your hands to rescue an adult who has fallen from the fourth floor. Not only that, the child is also easily crushed by th...

AI Technical Summary

Problems solved by technology

However, there are certain problems with child safety seats on the market. 1. The backrest angle of some seats cannot be adjusted. When the chair is installed in reverse, if the backrest angle cannot be adjusted, young children cannot lie in the seat, and the comfort of the child will be reduced

2. Although the other part of the child seat can adjust the angle, the recliner is generally complex in structure, inconvenient to operate, difficult to control when adjusting, poor in reliability, and prone to dislocation of the recliner, which poses a threat to children's safety 3. The seat can only be adjusted by the child's guardian
