Wearable bionic hydraulic mechanical lower limb rehabilitation walking aid

Abstract

The invention discloses a wearable bionic hydraulic mechanical lower limb rehabilitation walking aid and aims to solve problems of high leg weight, poor motor coordination with human bodies and the like of existing motor drive equipment to further improve smoothness and applicability of rehabilitation walking aid equipment. The walking aid comprises a back plate, a waist plate, triaxial hip joints, double-acting hydraulic cylinders, thigh bodies, bionic link knee joints, crus bodies, two-axial ankle joints and sole plates. The triaxial hip joints comprise hip joint adduction/abduction mechanisms, hip joint flexion and extension mechanisms and hip joint pronation/supination mechanisms. Each knee joint flexion and extension mechanism comprises a thigh connector, a front rocking rod, a rear rocking rod, a crus connector, a double-acting hydraulic cylinder and a limiting mechanism. The two-axial ankle joints comprise flexion and extension rotating shafts and adduction/abduction rotating shafts, an elastic steel plate externally presses each flexion and extension rotating shaft, and the other side of each steel plate is provided with a slot connected with the sole plate. Each ankle joint hydraulic cylinder is connected between a corresponding crus supporting plate and the corresponding adduction/abduction rotating shaft to control swing of the corresponding sole plate.

Description

technical field [0001] The invention relates to the technical field of lower limb rehabilitation walking aid equipment, in particular to a wearable bionic hydraulic lower limb rehabilitation walking aid mechanical device. Background technique [0002] With the development of society, patients with lower limb paralysis have gradually received social attention, and their demand for rehabilitation walking aids is becoming more and more urgent. The lower extremity rehabilitation training mechanical device has developed rapidly under this condition as a mechanical device for treating and solving daily activities. [0003] In addition, in industrial production, mechanical devices that assist movement can increase the endurance limit of the human body to improve the productivity of some manual workers. [0004] At present, most of the similar products on the market are driven by motors. The disadvantage of motor drives is that the legs are heavy and the coordination with the human...
