Headrest anti-collision early warning system

The invention provides a headrest anti-collision early warning system which comprises a four-way electric headrest mechanism and a sound mechanism arranged on the four-way electric headrest mechanism and further comprises a vehicle body distance sensor arranged on a vehicle body and used for measuring the distance between the vehicle and a front vehicle or/and a rear vehicle. The distance data output end of the vehicle body distance sensor is connected with the distance data input end of the intelligent driving controller; the intelligent driving controller controls the four-direction electric headrest mechanism to move or/and the sound mechanism to give out prompts according to distance data collected by the vehicle body distance sensor. The position of the headrest can be automatically adjusted, and the comfort of a passenger is improved. 本发明提出了一种头枕防碰撞预警系统，包括四向电动头枕机构及设置在所述四向电动头枕机构上的音响机构，还包括设置在车身上的用于测量本车与前车或/和后车距离的车身距离传感器；车身距离传感器的距离数据输出端与智能驾驶控制器的距离数据输入端相连；智能驾驶控制器根据车身距离传感器采集的距离数据，控制器四向电动头枕机构运动，或/和音响机构发出提示。本发明
