An unpowered wearable auxiliary walking assist mechanism

Abstract

The invention discloses an unpowered wearable auxiliary walking assisting mechanism. The unpowered wearable auxiliary walking assisting mechanism comprises driving force formation assemblies and knee joint assisting executing assemblies. Based on a lever principle and a crank slide block structure mechanism, the walking assisting mechanism disclosed by the invention adopts a working manner of same-side parallel driving input of left and right feet; a self-gravity effect of a human body is utilized and Bowden cables are used as a medium for transmitting a pulling force between the driving force formation assemblies and the knee joint assisting executing assemblies; the driving force formation assembly of the left foot provides a driving force for a left leg knee joint auxiliary torque executing assembly; the driving force formation assembly of the right foot provides a driving force for a right leg knee joint auxiliary torque executing assembly, so that torques for assisting left and right leg knee joints to bend and extend are generated in a walking process, and the aim of assisting walking is realized. The unpowered wearable auxiliary walking assisting mechanism disclosed by the invention has small inertia; the defects that the inertia of rigid mechanisms including a common leg assisting mechanism or an external skeleton robot and the like is great, damages to knee joints of people are easy to cause, the comfort is poor and the like are overcome, and the safety and comfort of the mechanism are remarkably improved.

Description

technical field [0001] The invention belongs to the field of knee joint auxiliary equipment and walking auxiliary equipment, and in particular relates to an unpowered wearable auxiliary walking assist mechanism. Background technique [0002] Walking is the foundation of the elderly's ability to take care of themselves in daily life, and it can improve the health of the elderly. However, as the age increases, the walking ability of the elderly will gradually decline, and the elderly with inconvenient legs and feet need people's support or walking aids to walk. In addition, mild stroke patients will also cause partial disability of lower limb motor ability, affecting the patient's mobility. Daily wearable walking aids can help the elderly and patients with partial disability of lower extremities improve their motor function, improve their self-care ability and health status, and have important rehabilitation medical significance for preventing degenerative changes. With the ...

AI Technical Summary

Problems solved by technology

Although this kind of walking assistance products can help the elderly or patients with partially disabled lower limbs maintain their balance or move, but because they have no power, they need to rely on the strength of their 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 the elderly or patients with partial disabilities of the lower limbs.
