Automobile, and headrest and control system thereof

Abstract

The invention discloses an automobile, and a headrest and a control system thereof. The headrest includes a headrest body and an adjusting device; the headrest body is installed on the top of a seat backrest; and the adjusting device can control the headrest body to perform displacement and / or rotation relative to the seat backrest, so that the headrest body can perform reliable support on the head and neck of a human body. The adjusting device can control the headrest body to perform displacement and / or rotation relative to the seat backrest, so that the position of the headrest body relativeto the seat backrest can be changed with multiple degrees of freedom; for human bodies with different statures, the headrest can perform reliable support on the heads and necks of the human bodies, so that protection effects on the heads and necks of the human bodies can be better achieved; and the above adjusting processes can be accomplished through the adjusting device, so that the adjusting processes are simple and convenient.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an automobile, a headrest and a control system thereof. Background technique [0002] With the development of society and the advancement of science and technology, automobiles have gradually become a common travel tool in people's lives due to their advantages such as convenience, speed, and convenience. However, the popularization of automobiles has also caused a large number of accidents while bringing convenience to people, which has brought pain and even death to countless people. [0003] Whiplash injury is a common injury in automobile accidents. When a car collides with the rear, due to inertia, the head and neck of the driver and human body are thrown out rapidly, just like whipping. Sudden overstretching of the neck can easily cause neck sprains, and in severe cases, it may even cause high paraplegia below the neck, causing great harm to people. [0004] In view of t...

AI Technical Summary

Problems solved by technology

[0008] First, the adjustment process is complicated. When adjusting, passengers first need to sit on the corresponding seat to feel the height difference between the current headrest and their own head, and then turn around and kneel on the seat to adjust the height of the headrest. It takes a lot of effort to pull out or press down the headrest, which is an extremely difficult operation for passengers with less strength; in this way, it makes it difficult or "lazy" for passengers to adjust the headrest, which is not conducive to Cultivation of safety awareness;

[0009] Second, the freedom of headrest adjustment is not enough. Due to the difference in personal sitting posture, when sitting down, the front and rear distances between the head and the headrest of different people are also different. If the front and back distance between the headrest and the human head is large, the It is difficult to effectively protect the head and neck
