The technical scheme adopted by the utility model for solving the technical problems is as follows: a smart damped prosthesis with active bending capabilities comprising a thigh member, a calf member and an ankle foot member, the calf member comprising: the hydraulic system comprises a rack and a joint head hinged to the top of the rack, wherein the bottom of the rack is connected with an ankle foot piece, a hydraulic cylinder is hinged to the rack, a hydraulic rod of the hydraulic cylinder is hinged to the joint head, an overflow valve servo motor is arranged on the hydraulic cylinder, and an active servo motor connected with the hinged end of the hydraulic rod is arranged on the joint head; and the hydraulic cylinder, the overflow servo motor and the active servo motor are all connected with a controller.
Furthermore, the hydraulic rod is connected with two pistons in the hydraulic cylinder, the middle of the two pistons is separated by a fixed plug to form two oil cavities for knee joint extension and flexion respectively, the two oil cavities are connected with a one-way valve and a needle valve driven by an overflow valve servo motor respectively, and the overflow valve servo motor receives a control instruction which is controlled and output by a controller and is used for controlling the opening of the needle valve to adjust the knee joint damping force.
Furthermore, a bending pressure sensor which can be contacted with the bottom end of the hydraulic cylinder is arranged at the bottom of the inner side of the frame.
Furthermore, a standing pressure sensor which can be contacted with the bottom end of the thigh piece is arranged at the upper part of the joint head.
Further, the hydraulic rod is hinged with the rear end of the joint head.
Further, the frame is hinged on two sides of the joint head.
Furthermore, a limiting plate for limiting the rotation range of the joint head is arranged on the rear side of the top of the rack.
Further, the controller is arranged on the rear side of the hydraulic cylinder.
The working principle is as follows: on the frame, the active servo motor is directly connected with the rotating shaft of the joint head, and can finish active bending; the standing pressure sensor and the bending pressure sensor collect standing pressure and bending pressure, the controller controls the active servo motor to rotate timely, and the overflow valve servo motor to rotate, so that the bending and stretching damping of the hydraulic cylinder is controlled, and the joint damping sense during walking is adjusted.
The utility model has the advantages of realizing the intelligent adjustment of the bending damping of the artificial limb, having the joint active bending function, being intelligent and labor-saving, greatly facilitating the walking of the patient, realizing the complete smooth walking process by a flexible feedback driving mechanism, realizing the real-time artificial limb mode switching by the signal acquisition of a multipoint sensor, realizing the smooth and correct damping adjustment by the driving of a high-speed motor, and improving the user experience of the patient.
