Intelligently adjustable headrest height car safety seat and headrest height adjustment method

Abstract

The invention discloses a car safety seat with an intelligently adjustable height of the headrest and a method for adjusting the height of the headrest. The safety seat includes a backrest, a headrest arranged on the backrest, and a height adjustment module for adjusting the height of the headrest. The adjustment module includes a power mechanism, a transmission mechanism, a detection sensor and a controller. The transmission mechanism is arranged in the main shell of the backrest. The headrest is fixedly connected with the transmission mechanism through a fixed connector. On the headrest, the power mechanism and the detection sensor are electrically connected to the controller; the controller receives the positional relationship information between the headrest and the human body in the safety seat detected by the detection sensor, and controls the action of the power mechanism. Under the action, the transmission mechanism drives the head support to move up and down. The car safety seat of the present invention adopts the sensor technology to automatically adjust the height of the headrest, adapts to the riding needs of different children or the same child in different periods and sitting postures, and saves time and effort.

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.

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
