Abstract
The invention discloses a double-piston stroke inductive type resistance change damping structure which comprises a cylinder. An upper piston and a lower piston are arranged in the cylinder. An inner barrel is arranged between the upper piston and the lower piston and sleeved with an outer barrel. The inner barrel and the outer barrel are movably connected. An inner damping hole is formed in the inner barrel. An outer damping hole is formed in the outer barrel. The inner damping hole or the outer damping hole is a through hole with the variable width or the variable height. Due to the fact that the outer damping hole or the inner damping hole is a through hole with the variable width or the variable height, when the relative positions of the upper piston and the lower piston are changed, the inner barrel and the outer barrel are driven so as to change the relative positions; and under the common effect of the outer damping hole and the inner damping hole, the size of a through hole making the outer damping hole and the inner damping hole coinciding with each other is changed, so that damping force is changed, and damping is changed.
