Abstract

The invention belongs to the field of lower limb assisting exoskeletons, and discloses a hip joint passive exoskeleton device based on energy time-sharing regulation. The hip joint passive exoskeletondevice comprises a waist arc-shaped support assembly, hip joint assemblies, thigh assemblies and elastic component connecting assemblies, wherein the waist arc-shaped support assembly comprises surrounding support devices and flexible bandages; each hip joint assembly comprises a hip joint inwards folding and outward unfolding connector and a hip joint bending and stretching connector; each thighassembly comprises a thigh outer-side connecting rod, a thigh front hoop and a thigh rear hoop; each elastic component connecting assembly comprises an L-shaped cantilever, an force arm, a digging rope clutch, an extension spring and a flexible rope. For the hip joint passive exoskeleton device based on energy time-sharing regulation provided by the invention, through the digging rope clutches triggered along with the joint angle, the extension springs stretch for storing the mechanical energy of the human body when the human hip joint does negative work and contract for releasing the energywhen the human hip joint does positive work, so that the time-sharing regulation on the mechanical energy of the human body is realized finally, the movement of the hip joint is assisted, the metabolic energy consumption generated during walk is reduced, in addition, the hip joint passive exoskeleton device has the advantages that the structure is simple, the cost is low, the weight is small, andthe wearing is comfortable.

Description

technical field [0001] The invention belongs to the field of lower limb power assist exoskeletons, and more particularly relates to a passive hip joint exoskeleton device based on energy time-sharing regulation. Background technique [0002] Traditional wheeled vehicles are easily limited by terrain conditions, and the good adaptability of human lower limbs to complex road surfaces makes them irreplaceable in such occasions. However, the physical strength of humans cannot be compared with the carrying capacity of vehicles. Due to the friction of a large number of soft tissues inside the limbs and the existence of dissipative energy such as sliding friction on the soles of the feet, the utilization rate of metabolic energy per body weight of the limbs is not very economical. At the same time, factors such as muscle fatigue and metabolic energy consumption caused by long-term walking make the body's physical function weaker. The lower extremity exoskeleton, as a wearable mech...
