Design of Disables pneumatic knee

The overall structure of the pneumatic knee joint: the pneumatic knee joint is composed of a four-bar linkage mechanism and a damping cylinder  According to the requirement that the rotation range of the knee joint of the human body is less than 180°, the four-bar linkage mechanism can adopt a double rocker structure. To ensure the stability of the simulated human body when it is standing, the rotation direction of the joystick should be limited. It can only start from the limit point, rotate clockwise and return to the limit point counterclockwise. The limit point is exactly the position where the person is standing. Four The connecting rod mechanism is low-amplitude movement, with low wear and tear, and can meet the requirements of long-term use. The connecting rod mechanism is simple, small in size, light in weight, and suitable for the requirements of prosthetics. The design of 0.6～1MPa can meet the needs of 60～80kg weight. The damper can be designed on the cylinder body or on the piston.
