1. A damping device, comprising:
a damping member;
a structural bracket, wherein the structural bracket connects the damping member to a mass block arranged on an object to be damped, wherein the structural bracket comprises a gear, and the gear is rotatably arranged on the structural bracket;
a guide rail having a predetermined curvature, wherein a first end of the guide rail is configured to be rotatably connected to the object to be damped, and a second end of the guide rail is supported on the structural bracket, wherein a side portion of the guide rail is formed with a tooth portion that meshes with the gear,
wherein, when the mass block swings, the swing of the mass block is converted into rotation through meshing transmission between the guide rail and the gear, and the rotation is transmitted to the damping member.
