Rear fall protection device for lower limb exoskeleton robot

Abstract

The invention relates to the field of wearable rehabilitation medical treatment, in particular to a rear fall protection device for a lower limb exoskeleton robot. The device comprises a lower limb exoskeleton robot body, and the lower limb exoskeleton robot body comprises a lumbar support, mechanical legs and pressure shoes, and is characterized in that a protection device is arranged on the backof the lumbar support. The protection device comprises a protective shell, a head protector, a control panel, a back cotton pad and a rotating plate. Two locking buckles are symmetrically arranged onboth sides of the rotating plate, the two locking buckles and the pressure shoes are electrically connected to a control board, a wireless module is arranged on the control board, and the locking buckles can be opened by the parallel control of two modes. The rear fall protection device for the lower limb exoskeleton robot can cooperate with the exoskeleton robot body, can effectively reduce thedamage of a human body when a person falls, and can be reused.

Description

technical field [0001] The invention relates to the field of wearable rehabilitation medicine, in particular to a fall protection device for a lower extremity exoskeleton robot. Background technique [0002] At present, the lower extremity exoskeleton robot is a human-machine parallel system, which is mainly used in rehabilitation medicine and assisting in walking direction. During the walking process of normal people, the human body may fall due to its own physical condition or external conditions, especially for the elderly. People, whose falls have a high rate of medical treatment and hospitalization, have brought serious economic and social burdens. With the aging of Chinese society, the problem of falls has also received great attention from the industry. After wearing exoskeleton robots, The weight of the overall human-machine system increases, causing more serious injuries when falling, and the degree of damage to the body is also different in the direction of the fal...

[0002] At present, the lower extremity exoskeleton robot is a human-machine parallel system, which is mainly used in rehabilitation medicine and assisting in walking direction. During the walking process of normal people, the human body may fall due to its own physical condition or external conditions, especially for the elderly. People, whose falls have a high rate of medical treatment and hospitalization, have brought serious economic and social burdens. With the aging of Chinese society, the problem of falls has also received great attention from the industry. After wearing exoskeleton robots, The weight of the overall human-machine system increases, causing more serious injuries when falling, and the degree of damage to the body is also different in the direction of the fall. When falling forward or sideways, there are crutches or arms as support, and the damage to the human body will Correspondingly, when falling backwards, it is easier to cause great damage to the human body. Most of the existing protection devices for human body fall use inflatable airbags. The device is equipped with sensors, protective sleeves, cushioning airbags, etc. at the hip joint. The fall behavior is judged by the sensors, and the gas stored in the gas cylinder is triggered to rush into the airbag to ensure that when the human body falls to the ground, the back of the head Cushioning with the cervical spine, but the repeatability of the airbag used in this method is poor. After each fall, the airbag needs to be reinflated. For the fall protection measures of the exoskeleton rehabilitation robot, there are also fixed brackets at this stage. Fixing the upper body of the human body can protect the human body in this way, but due to the fixity of the facility, it cannot be used for daily walking. A protective device that can effectively reduce the damage to the human body and can be reused
