Hydraulic buffering leg cushion

A hydraulic buffering leg cushion, mounted to a supporting platform, comprising:

• a leg cushion body, provided with a leg cushion accommodating space, and including an upper cover, and a lower cover, wherein the upper cover is arranged on the lower cover;
• a movable unit, received in the leg cushion accommodating space, and including a piston, a membrane assembly, a rubber bowl, and a movable portion, wherein the rubber bowl is clamped, at its outer circumference, by and between the upper cover and the lower cover, so as to partition a damping accommodating space for receiving damping oil, and the damping accommodating space includes a first damping accommodating space located above the piston, and a second damping accommodating space located below the piston, and wherein the movable portion and the rubber bowl are pressed, in sequence, onto the piston, and the piston is provided with a damping channel for communicating with the first damping accommodating space and with the second damping accommodating space, and wherein the membrane assembly is disposed underneath the piston, so as to press against the piston and to make the damping channel unable to communicate with the first damping accommodating space and the second damping accommodating space, or on the other hand, the membrane assembly does not press against the piston so as to make the damping channel communicate with the first damping accommodating space and the second damping accommodating space, and the piston is connected with the lower cover through a restoring spring, and the restoring spring passes through the membrane assembly;
• and
• a fixed connecting member, fixedly arranged on the movable portion of the movable unit.
