The invention discloses a linear positioning damper and an automobile seat armrest, and belongs to the field of dampers and automobile armrests. The automobile seat armrest comprises a linear positioning damper and an automobile seat armrest, the linear positioning damper comprises a plurality of damping fins and a rotating shaft, each damping fin comprises a rocker arm and a holding ring, and the holding ring is provided with a notch to clamp the rotating shaft. The inner ring of the holding ring is provided with a smooth notch used for eliminating stress and guaranteeing that the clamping force of the holding ring is constant, and the damping fins are sequentially attached to and hold the rotating shaft. A table plate of the automobile seat armrest is rotationally connected with one end of a cantilever through a second damper, the other end of the cantilever is rotationally connected with a connecting arm through a third damper, a supporting beam is further arranged between the cantilever and the connecting arm, and the bottom of the connecting arm is rotationally connected with a mounting arm through a fourth damper. According to the linear positioning damper, the rotating shaft is wrapped by the damping fins, the damping force is adjusted by changing the number of the damping fins, damping adjustment is smoother, hovering at any angle can be achieved, and the service life is prolonged.
本发明公开了一种线性定位阻尼以及汽车座椅扶手,属于阻尼及汽车扶手领域。本发明包括线性定位阻尼及汽车座椅扶手,线性定位阻尼包括若干阻尼片以及转轴,阻尼片包括摇臂、抱环,抱环设有缺口以实现对转轴的夹持。抱环的内环设有圆滑的凹口用于消除应力并保证抱环的挟持力持久不变,阻尼片依次贴合并抱住转轴。汽车座椅扶手的桌板通过第二阻尼与悬臂的一端可转动式连接,悬臂的另一端通过第三阻尼与连接臂转动式连接,悬臂与连接臂之间还设有支撑梁,连接臂的底部通过第四阻尼与安装臂转动式连接。本发明提供的线性定位阻尼采用若干阻尼片包裹转轴,通过改变阻尼片的数量以调节阻尼力的大小,阻尼调节更加顺畅,可任意角度悬停并提高使用寿命。
