The application discloses a joint detachable artificial limb, which comprises a thigh artificial limb, a lower leg artificial limb and a foot artificial limb, a waistband is arranged above the thigh artificial limb, fixed blocks and magic tape thorn surfaces are fixedly connected to the front and back sides of the thigh artificial limb, a through slot is formed in the fixed block, a connecting belt is movably arranged in the through slot, and the magic tape hair surfaces are fixedly connected to the side of the connecting belt close to the thigh artificial limb.

The utility model discloses an artificial lower limb capable of intelligently adjusting damping based on an IMU (Inertial Measurement Unit) and magnetorheological fluid. Comprising a stump mounting sleeve, an artificial thigh part, a knee rotary magnetorheological fluid damper, an artificial shank part, a leg telescopic magnetorheological fluid damper, an ankle rotary magnetorheological fluid damper, an artificial foot part, a foot telescopic magnetorheological fluid damper, an inertia measurement sensor, a first pressure sensor, a second pressure sensor and a damping controller, the stump mounting sleeve is arranged at the upper end of the thigh artificial limb part and used for being connected with a thigh amputation part, and the bottom end of the thigh artificial limb part is rotationally connected with the shank artificial limb part through the knee rotary magnetorheological fluid damper; the bottom end of the lower leg artificial limb part is connected with the artificial foot part through the ankle rotary magnetorheological fluid damper, a gravity center cavity is formed in the gravity center position of the whole artificial lower limb, and the inertia measurement sensor is installed in the gravity center cavity.

The application belongs to the technical field of human exoskeletons, and specifically discloses a thigh prosthesis knee joint exoskeleton and a control method thereof. The application comprises a driving module, a thigh fixing module, a shank fixing module and a knee joint connecting module, wherein the exoskeleton is fixed on the prosthesis through the thigh fixing module, the shank fixing module and the knee joint connecting module. The rotation movement of the motor output shaft is converted into the linear movement of the sliding block through the screw transmission mechanism in the driving module, and then the linear movement of the sliding block is converted into the rotation movement of the shank of the prosthesis around the rotation shaft of the knee joint of the prosthesis through the crank slider mechanism, and the size of the initial installation angle is set by the variable force arm characteristics of the crank slider mechanism, so that the output torque of the shank of the prosthesis can better match the gait of the user, thereby significantly improving the gait stability, power assistance efficiency and wearing comfort of the existing unpowered prosthesis.
