Rehabilitation walking-aid assistive device

Abstract

Disclosed is a rehabilitation walking-aid assistive device. The rehabilitation walking-aid assistive device comprises an exoskeleton frame, an elastic energy storage device, a clutch and a sensor, wherein the exoskeleton frame is worn on the shanks and legs of a wearer, one end of the elastic energy storage device is fixed to the exoskeleton frame, and in a walking process, energy can be stored and released to reduce muscle strength requirements and lower walking energy consumption, the clutch is fixed to the exoskeleton frame and one end of the clutch is connected with the other end of the elastic energy storage device; the sensor is connected with the other end of the clutch, and is used for sensing information of pressure exerted by the sole and controlling the clutch based on the information of the pressure. The sensor transmits a sensed signal to the clutch, and the clutch controls an energy storing and releasing opportunity of the elastic energy storage device based on the received signal, so that the elastic energy storage device is matched with gaits of the wearer. The rehabilitation walking-aid assistive device can lower the maximal muscle strength requirement and energy consumption in the walking process of the wearer, old people with the weaker strength can walk longer, and the rehabilitation walking-aid assistive device can also assist other injury patients with the weak strength in legs in conducting rehabilitation walking training.

Description

technical field [0001] The invention relates to a walking aid for rehabilitation, which can help elderly people with weakened leg muscles and injured and sick people to walk and perform rehabilitation training. It belongs to the field of rehabilitation assistive technology. Background technique [0002] When a person enters the old age, the muscle strength of the legs will drop significantly, which will make the elderly reluctant to walk outdoors, and further lead to a decline in their various physiological functions. At present, the number of elderly people over 60 years old in my country has reached 230 million, and the social problems of aging are becoming increasingly prominent. The use of rehabilitation walking aids can reduce the muscle strength and energy requirements of people walking, enable the elderly to participate in outdoor sports more actively, delay the aging process, and reduce the burden on families and society.
