Abstract

A damping device (110), wherein a housing (111) defines a chamber (240) filled with a damping liquid, and partition portions (213) on an inner wall (211) of the housing (111) define extreme positions (201); a damping control core (112) in the chamber (240) can rotate relative to the housing (111), and wing portions (232) of the damping control core (112) are provided with limiting surfaces (233) capable of being stopped by the partition portions (213); the chamber (240) comprises proximal accommodating cavities (241) and distal accommodating cavities (242) formed by partitioning by the partition portions (213) or the wing portions (232), and the volumes of each proximal accommodating cavity (241) and the corresponding distal accommodating cavity (213) change oppositely along with the movement of the damping control core (112) relative to the housing (111); inner connection channels (250) are formed in the wing portions (232) or the partition portions (213), and outer connection channels (270) are formed between the wing portions (232) and the inner wall (211) or between the partition portions (213) and the damping control core (112); and the inner and outer connection channels can be controllably connected to the proximal accommodating cavities (241) and the distal accommodating cavities (242); when the limiting surfaces (233) are not between a control position and the extreme positions (201) or when the limiting surfaces (233) move away from the extreme positions (201) between the control position and the extreme positions (201), the damping device (110) provides small damping; and when the limiting surfaces (233) move towards the extreme positions (201) between the control position and the extreme positions (201), the damping device (110) provides large damping.
