Bionic energy-storing walking aiding external skeleton

Abstract

The invention discloses a bionic energy-storing walking aiding external skeleton. The bionic energy-storing walking aiding external skeleton comprises two foot supports, two lower leg support bars, two thigh support bars, a hip joint assembly, and an energy-storing assembly, wherein the hip joint assembly comprises two pelvis brackets and a connecting piece connected between the two pelvis brackets; the two pelvis brackets are connected to the thigh support bars through rotatable hip joints respectively; the energy-storing assembly is connected between the pelvis brackets and the thigh support bars, and is used for storing or releasing energy in order to assist a paraplegic patient in switching between a standing posture and a sitting posture. According to the walking aiding external skeleton disclosed by the invention, energy generated through stretching exercise of the waist of the paraplegic patient on a sagittal plane is stored in the energy-storing assembly, the energy is released during hip flection to provide hip flection assistance, a part of energy is stored in the energy-storing assembly which is connected with the pelvis brackets and the thigh support bars and is used for simulating the hip joint extensor of a human body in a hip flection, and a flexible girdle for providing hip extension assistance is used for aiding walking of the external skeleton, so that the physical energy consumption of the patient during walking is lowered.

AI Technical Summary

Benefits of technology

This patented technology allows an orthopedic device called BIO-SUPPORT helps people with disabilities walk more comfortably without having them physically restrain their legs or stretches out during exercise movements. It uses its own power source (battery) connected between two parts - one on each side – which simulates how much weight your body needs while sitting down at home. When they are bent over towards this wheelchair, some energy from it goes into storing there instead. By doing these things we reduce our physical effort compared to trying hard just like jumping up again after being tired.

Problems solved by technology

This technical problem addressed in this patented text relates to improving prosthetic devices called interstitroplegy legs or staggerers, particularly those implanted during surgery due to their limited ability to actively control motion. Existing solutions have limitations including lack of energy stored and useable energy sources, difficulty fitting them around obstacles like low screw injuries, poor stability caused by existing designs, and potential safety concerns associated therewith.
