Squatting-type human lower limb joint biomimetic device

Abstract

The invention relates to a squatting-type human body lower limb joint biomimetic device. The technical scheme is as follows, a sliding table which is driven by a first motor and slides up and down oris fixed in the height direction of a vertical supporting plate is arranged on the vertical supporting plate, a horizontal fixed shaft is fixed on the sliding table, the middle part of the fixed shaftis connected to a femoral shaft through a first universal joint, the lower end of the femoral shaft is fixedly connected to a femur lower end simulation block, a steel wire rope is wound on a rotating shaft, on which a second motor is fixed, of a base, one end of the steel wire rope is fixed on the rotating shaft of the second motor, and the other end extends upwards, bypasses a fixed pulley block fixed on the sliding table and then is connected to the upper end of a patella ligament simulation belt. According to the invention, the condition of applying squatting force is acquired through a tension sensor, the motion trail signal in the squatting process is acquired through a gyroscope, and the stress of knee joints and soles is acquired through strain gauges, so that the motion trail andthe stress condition of squatting motion of the lower limbs of a human body under the condition of a certain stress curve are simulated.

Description

Technical field [0001] The invention relates to the field of biomechanics, in particular to a squatting bionic device for human lower limb joints. Background technique [0002] The most important thing in the design process of human lower limb devices is the structural design of hip joints, knee joints and ankle joints. The hip joint is a ball and socket joint, and the change in the position of the rotation center during rotation is not obvious; although the ankle joint is a compound joint, its rotation angle is small during walking, so the change in the rotation center is not obvious. The exoskeleton joints of these two parts are considered to be simplified into a single joint that rotates around a fixed axis; the knee joint is a compound joint and the largest and most complex joint in the human body. It plays an extremely important role in the load-bearing and movement of the human body. The knee joint It consists of the skeleton, the distal end of the femur, the proximal...
