Title:
SQUATTING HUMAN LOWER LIMBS JOINT BIOMIMETIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/253827
Kind Code:
A1
Abstract:
A squatting human lower limbs joint biomimetic device. A vertical supporting plate (23) is provided with a sliding platform (4) driven by a first motor (1) and sliding up and down or fixed in the height direction of the vertical supporting plate (23), a horizontal fixing shaft (41) is fixed on the sliding platform (4), a femoral shaft (7) is connected to the middle part of the fixing shaft (41) by means of a first universal joint, a femoral lower end simulation block (8) is fixedly connected to the lower end of the femoral shaft (7), a steel wire rope (6) is wound around a rotating shaft of a second motor (19) fixed on a base (18), one end of the steel wire rope (6) is fixed on the rotating shaft of the second motor (19), and the other end extends upwards, passes a fixed pulley set (5) fixed on the sliding platform (4)and then is connected to the upper end of a patellar ligament simulation strap (11). An applied squatting force is acquired by a tension sensor, a movement trajectory signal during a squat process is acquired by a gyroscope, and forces applied to the knee joint and the sole are acquired by a strain gauge, thereby simulating the movement trajectory and force of the human lower limbs when subjected to a certain force curve and performing squatting movement.
