Hip joint walking aid

Abstract

The present invention discloses a hip joint walking aid. The hip joint walking aid comprises a lumbar fixation device, an energy storage and release device and a thigh support device; the energy storage and release device is connected with the lumbar fixation device and the thigh support device and the energy storage and release device comprises energy storage and release device outer shells, winding mechanism elastic devices, spline shaft sleeves, central rotating shafts, tension and compression elastic devices, rotating devices and shaft end stopping devices; inner rings of the winding mechanism elastic devices are fixed on outer rings of the spline shaft sleeves, outer rings of the winding mechanism elastic devices are fixed on inner walls of the energy storage and release device outershells, the tension and compression elastic devices sleeve the central rotating shafts and are in a compression state, the shaft end stopping devices are fixed on the central rotating shafts, the shaft end stopping devices are clamped at limiting positions of the energy storage and release device outer shells, and the rotating devices are fixed on one sides of the central rotating shafts. The hipjoint walking aid can provide effective walking assisting force for a user and has simple and light structure, low cost, reliable work and good wearing comfort.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a hip joint walker. Background technique [0002] At present, the number of robotic equipment in the field of rehabilitation medicine at home and abroad is gradually increasing. Walking robot is a type of rehabilitation medical equipment that can help patients with walking impairments recover their independent walking ability. [0003] Most of the current walking aids are driven by motors. Electric drive power-assisted joints use motors as driving components, resulting in a large weight and complex structure of the power-assisted joints. Due to the introduction of motors, the cost of power-assisted joints has increased significantly. The difficulty of maintenance and maintenance increases, and the reliability of joint work decreases. Since the motor produces a certain amount of noise, when the user wears the power-assisted joint, the comfort of wearing it will be greatly reduced...

AI Technical Summary

Problems solved by technology

[0003] Most of the current walking aids are driven by motors. Electric drive power-assisted joints use motors as driving components, resulting in a large weight and complex structure of the power-assisted joints. Due to the introduction of motors, the cost of power-assisted joints has increased significantly. The maintenance and maintenance difficulty increases, and the reliability of the joint work decreases

Due to the noise generated when the motor is working, when the user wears the power-assisted joint, the wearing comfort will be greatly reduced

Since the motor needs to consume electric energy, the battery life of the electric drive power-assisted joint also has a large defect.
