Power-assisted walking device with auxiliary lower limbs

Abstract

A power-assisted walking device with auxiliary lower limbs is composed of back support, active lower limbs, auxiliary lower limbs, driving motor, power supply system, sensing system and control system. The back bracket, active lower limb and auxiliary lower limb all have the function of length adjustment, so as to meet the requirements of body width, height and leg length of different users. Whenworking, under the action and control of driving motor (4), power supply system (5), sensing system (6) and control system (7), the active lower limb (2) and auxiliary lower limb (3) can advance in turn according to a certain logical order to ensure the balance and stability of the user when walking.

Description

Technical field [0001] The invention relates to the field of power-assisted mechanical exoskeleton equipment, in particular to a power-assisted walking device with auxiliary lower limbs. technical background [0002] With the advent of an aging society, how to help the elderly who are physically weak, inconvenient to walk, and have insufficient stamina to effectively integrate into the society has attracted more and more attention. The development of a booster equipment suitable for the elderly with lower limb injuries, especially muscle strength degradation, can not only help them expand their range of activities, improve their quality of life, and restore their confidence in life, but also to a certain extent can relieve the social pressure brought by aging And family pressure. Although there are many wheelchairs with different structures and functions on the market, due to the inherent deficiencies in the design and construction of my country’s infrastructure, the passage of ...

Problems solved by technology

Although there are many wheelchairs with different structures and functions to choose from on the market, due to the inherent deficiencies in the design and construction of our country's infrastructure, the passage of wheeled equipment is more or less difficult when going up and down stairs or in some public places and leisure places. Subject to certain restrictions, and because the user's lower limbs cannot be effectively exercised, it is not conducive to the treatment and rehabilitation of lower limb diseases

In recent years, there are many kinds of power-assisted devices invented for the elderly who have difficulty walking. The common disadvantages are complex and bulky structures, high prices, and unaffordability for ordinary families, and most of them cannot be separated from the design of the two lower limbs based on anthropomorphic mechanical exoskeletons. concept, it is quite difficult to promote it

In fact, the elderly who need to wear power-assisted devices are not only slowed down due to muscle atrophy of the lower limbs and spinal cord injury, but also many of them are accompanied by cardiovascular diseases such as stroke and hemiplegia. Inability to recover and accurately master walking motor skills, especially body balance skills while walking

The purpose of the present invention is to provide a simple structure, stable and reliable power-assisted mechanical exoskeleton equipment technology with auxiliary lower limbs to solve the problems of balance stability and power-assisted device reliability when the elderly walk
