Automobile safety seat with intelligent and adjustable head support height and head support height adjusting method

Abstract

The invention discloses an automobile safety seat with an intelligent and adjustable head support height and a head support height adjusting method. The automobile safety seat with the intelligent and adjustable head support height comprises a backrest, a head support and a height adjusting module, wherein the head support is arranged on the backrest, and the height adjusting module is used for adjusting the height of the head support; the height adjusting module comprises a power mechanism, a transmission mechanism, a detection sensor and a controller; the transmission mechanism is arranged in a main shell of the backrest; the head support is fixedly connected with the transmission mechanism through a fixed connecting piece; the transmission mechanism is connected with an output end of the power mechanism; the detection sensor is arranged on the head support; the power mechanism and the detection sensor are electrically connected with the controller; the controller receives position relation information, detected by the detection sensor, of the head support and a human body sitting in the safety seat and controls the power mechanism to act; and under the driving effect of the power mechanism, the transmission mechanism drives the head support to move up and down. According to the automobile safety seat with the intelligent and adjustable head support height, the height of the head support is automatically adjusted by using a sensing technology to adapt to taking demands of sitting postures of different children or the same child at different times; and therefore, the automobile safety seat with the intelligent and adjustable head support height is time-saving and labor-saving.

Description

technical field [0001] The invention relates to the field of automobile safety seats, in particular to an automobile safety seat with an intelligently adjustable height of the headrest and a method for adjusting the height of the headrest. Background technique [0002] The car safety seat has become an essential product for children when traveling in a vehicle. Its basic function is that it can cushion the impact and protect the child when the vehicle equipped with the car safety seat collides.

Among them, the headrest on the car safety seat is particularly critical for the protection of children's heads. [0003] In order to ensure that the headrest plays an important role on the child's head, the height of the headrest needs to be adjusted according to the height of the child's shoulders. A low headrest height will affect the child's...

AI Technical Summary

Problems solved by technology

[0005] First, the height is adjusted manually, which cannot ensure that the adjusted height is the optimal height position;

[0006] Second, after adjusting the height of the headrest once, it will not be adjusted for a long time, and the height of the headrest cannot be fine-tuned with the growth of the child's height or the difference in the child's sitting posture;

[0007] Third, if children of different heights use the same safety seat, the headrest must be manually adjusted every time, which is time-consuming and laborious
