The centrifugal locking mechanism comprises an inner shell and an armrest rotating shaft, the armrest rotating shaft is arranged on one side of the inner shell, a rotating block is arranged on the other side of the inner shell, and the outer end of the armrest rotating shaft can penetrate through the inner shell to be connected with the rotating block. An annular inner toothed plate is connected to the side, away from the armrest rotating shaft, of the inner shell, locking oblique teeth are distributed on the inner side wall of the inner toothed plate, an eccentric centrifugal locking block is hinged to the rotating block, the centrifugal locking block extends into the inner toothed plate, rotation stopping oblique teeth are arranged at the bottom of the centrifugal locking block and correspond to the locking oblique teeth, and the rotation stopping oblique teeth correspond to the locking oblique teeth. And the locking helical teeth can be correspondingly wedged with the rotation stopping helical teeth, and the mechanism is arranged on the inner side of the seat framework and is connected with a handrail. The collision locking device has the beneficial effects that the complete collision locking function can be achieved, the safety risk is reduced, and the locking function is high in response speed, is not affected by the installation inclination angle of the backrest, is irrelevant to the collision acceleration direction and is only relevant to collision energy.

    本发明公开了一种离心锁止机构及座椅扶手,包括内壳体和扶手转轴,在所述内壳体的一侧设置有所述扶手转轴,在该内壳体的另一侧设置有旋转块,所述扶手转轴的外端能够穿过内壳体与所述旋转块连接,在远离扶手转轴一侧的内壳体上连接有环状内齿板,所述内齿板的内侧壁上布有锁止斜齿,在所述旋转块上铰接有偏心离心锁止块,所述离心锁止块伸入内齿板内,该离心锁止块的底部对应所述锁止斜齿设置有止旋斜齿,所述锁止斜齿能够与该止旋斜齿对应楔紧,该机构安装在座椅骨架内侧并与扶手相连。本发明的有益效果:能够实现完整的碰撞锁止功能,降低安全风险,其锁止功能响应速度快,且不受靠背安装倾角影响,跟碰撞加速度方向无关,只跟碰撞能量有关。
