A wearable lower limb flexible power-assisted outerwear

Abstract

The invention relates to a wearable power-assisting flexible outer garment for lower limbs. The flexible power-assisting outer garment comprises an outer garment body, Bowden cable units, two linear traction units and a gait detection unit. Normal walking motion can be assisted when a human body wears the power-assisting flexible outer garment for lower limbs. The outer garment body is attached to the skin of the lower limbs or the surface of clothes; the Bowden cable units are distributed along the outer garment body; according to a signal of the gait detection unit, the linear traction units drive Bowden cables to pull and assist ankle joints and hip joints of the human body at appropriate moments. The two linear traction units are stacked together to be placed in a backpack, each linear traction unit pulls two sets of Bowden cable units to respectively pull the hip joints and the ankle joints of the lower limbs of the human body, so as to assist in the forward flexion of the hip joints and the downward flexion of the ankle joints to reduce acting forces required by Achilles tendon of feet and thighs and shanks to lift legs, thereby reducing energy consumption of corresponding muscles of the lower limbs of the human body and assisting the lower limes in moving.

Description

technical field [0001] The invention relates to a power-assisted outerwear, in particular to a wearable and flexible power-assisted outerwear. Background technique [0002] The lower limb flexible power-supporting garment can be worn for a long time, and it is used for long-distance weight-bearing walking and continuous load-bearing transportation by healthy people, especially soldiers. Metabolic consumption and delay of physical fatigue, reducing the risk of injury caused by long-term, high-load walking. For patients with motor dysfunction, the flexible power-assisted garment can provide an appropriate amount of external assistance, which is conducive to stimulating and repairing the connection between the limbs and the damaged central nervous system; at the same time, it helps to improve the strength regeneration ability of the human physiological joints, thereby improving the patient's walking gait and efficiency. The difficulty of the flexible power-assisted outerwear ...

AI Technical Summary

Problems solved by technology

Kawamura et al. developed a walking assistance system to address the aging of leg muscles, which compensates the strength during the forward swing of the lower limbs to increase the walking step length, but the assistance system cannot provide enough force, and the walking assistance effect is not obvious
