A portable flexible walking aid

Abstract

The invention discloses portable flexible walking assisting equipment. The portable flexible walking assisting equipment comprises knee joint flexible actuating mechanisms (1), air pressure forming mechanisms (2), flexible fixing bands (3) and air pipes (4). In the walking process of a person, the air pressure forming mechanisms (2) make the air pressure of air bags of the knee joint flexible actuating mechanisms (1) rapidly increased or decreased, and the knee joint flexible actuating mechanisms (1) generate torque assisting the knees in bending and stretching. The weight of the person is adopted as the driving force of the equipment, and no other additional energy is needed; the flexible driving mode combining the pneumatic driving force of the air bags and the elastic force of torsion springs is adopted for the actuating parts, and the pneumatic driving force and the elastic force compensate for each other in the walking process of the person. By adopting the flexible driving mode combining the pneumatic driving force and the elastic force of the torsion springs, the structural inertia is small, the defects that a rigid mechanism like a common leg assistance device or an exoskeleton robot is large in inertia, likely to injure the knee joints of a person, poor in comfort and the like are overcome, and the safety and comfort of the equipment are improved.

Description

technical field [0001] The invention belongs to the field of knee joint auxiliary equipment and flexible walking auxiliary equipment, and particularly relates to a portable flexible walking auxiliary equipment suitable for people with reduced lower limb exercise capacity or partially disabled lower limb movement. Background technique [0002] Due to the decline of physiological functions, in the aging process from middle age to old age, there are phenomena such as unsteady standing and walking, reduced range of joint motion, and decreased ligament elasticity and absolute muscle strength. Studies have shown that falls are the leading cause of sudden death in people over the age of 75. A large part of this is related to the physiological degeneration and injury of the knee joint. This has brought great inconvenience to the life of the elderly, and the quality of life cannot be guaranteed, seriously impairing physical and mental health. However, in our country, the developmen...

Problems solved by technology

Although such assistive products can help the elderly or patients with partial disabilities of the lower limbs to maintain balance or move, but because they have no power, they need to rely on the strength of the upper limbs, which will make people feel strenuous in walking

In addition, exoskeleton robots are also a hot spot in the research of walking assistance, but their volume and weight are large, the inertia of the rigid mechanism is large, and the comfort is poor. At present, they have not been practically applied to the daily walking of people with reduced lower limb movement ability or partially disabled lower limb movement. middle
