The invention provides a turnover-speed-controllable vehicle seat headrest turnover mechanism which comprises a headrest rod and a horizontal rotating shaft and further comprises an adjusting motor, a left side fixing support and a right side fixing support, the headrest rod is vertically welded to the horizontal rotating shaft, the left end of the horizontal rotating shaft is rotatably installed on the left side fixing support through a self-lubricating bush, and the right end of the horizontal rotating shaft is rotatably installed on the right side fixing support through a self-lubricating bush. The right end of the horizontal rotating shaft is rotationally installed on the right side fixing support through a self-lubricating bush, and the adjusting motor is fixed to the left side fixing support or the right side fixing support and drives the horizontal rotating shaft to rotate through a motor output shaft. According to the electric folding headrest, electric folding of the headrest rod can be rapidly achieved, the folding speed is controllable, and the problem that impact force at the moment of unlocking is too large due to the fact that a traditional headrest uses mechanical unlocking is solved; and moreover, a modular design is adopted, so that the device can be directly mounted on an existing automobile rear-row seat framework or a framework platform.

    本发明提出了一种翻转速度可控的车用座椅头枕翻折机构,包括头枕杆和水平旋转轴,还包括调节电机、左侧固定支架和右侧固定支架,头枕杆垂直焊接在水平旋转轴上,水平旋转轴的左端通过自润滑衬套转动安装于左侧固定支架上,水平旋转轴的右端通过自润滑衬套转动安装于右侧固定支架上,调节电机固定于左侧固定支架上或右侧固定支架上,并通过电机输出轴带动水平旋转轴转动。本发明能快速实现头枕杆的电动翻折,翻折速度可控,解决了传统头枕使用机械解锁带来的解锁瞬间冲击力过大的问题;而且采用了模块化设计,可直接安装于现有的汽车后排座椅骨架或骨架平台上。
