Drop prevention system based on lower limb exoskeleton robots

Abstract

The invention relates to a drop prevention system based on lower limb exoskeleton robots. The drop prevention system comprises the lower limb exoskeleton robots, a wide-plain-strip elastic band and amain control box, wherein the main control box is arranged at the upper side of the wide-plain-strip elastic band; the main control box comprises a power supply module, a gravity center acquisition module and a data analysis module; the gravity center acquisition module and the data analysis module are integrated on a bottom plate, and the bottom plate is composed of various small components; thewide-plain-strip elastic band is internally provided with a vibrator; the number of the lower limb exoskeleton robots is two, and the lower limb exoskeleton robots are arranged at the two sides of thewide-plain-strip elastic band respectively. The drop prevention system has high adaptability, can be adapted to all lower limb exoskeleton robots such as walking aid exoskeleton robots or assisting exoskeleton robots, and various functions can be added according to the requirements of a wearer, and the expansibility is high.

Description

technical field [0001] The invention relates to the field of exoskeleton robot system control, in particular to an anti-fall system based on a lower limb exoskeleton robot. Background technique [0002] The lower extremity exoskeleton robot is a human-machine integrated mechanical device that can be worn by humans. It integrates robotics, bionics, ergonomics and other fields of technology. Its main function is to expand or enhance a person's physiological functions, and to provide assistance, protection, and support for the human body. It is currently mainly used in medical rehabilitation and military fields. For example, paraplegic patients can stand up again with the help of lower limb exoskeleton robots, and can drive the human body to walk through lower limb exoskeleton robots, and perform rehabilitation training to slow down the atrophy of human lower limb muscles. [0003] When wearing a lower extremity exoskeleton robot, one of the most critical issues is how to main...

Problems solved by technology

However, this patent does not consider other situations where the exoskeleton robot falls, but only considers a special case of power failure

The patent with the publication number CN103263339 B introduces a bionic control method for the anti-fall gait of an exoskeleton walker robot, which judges the patient's fall state and integrates the human body posture reflection mechanism. Response to emergencies, once the gait simulation is wrong, resulting in an unstable center of gravity, the body cannot adjust the center of gravity in time, and the patient will still fall and cause serious injury
