Modular joint for lower limb rehabilitation training exoskeleton

Abstract

The invention provides a modular joint for a lower limb rehabilitation training exoskeleton, and relates to an exoskeleton robot. The modular joint includes a transmission and limiting mechanism, thetransmission and limiting mechanism includes a cover plate, a driving motor, a bracket, a bottom plate, a transmission assembly and an output connecting rod, the cover plate and the bottom plate are connected together in a buckled mode, and the driving motor, the bracket, the transmission assembly and the output connecting rod are arranged between the cover plate and the bottom plate; the drivingmotor is mounted on the bracket, the bracket is mounted on the bottom plate, the driving motor drives the transmission assembly, one end of the output connecting rod is connected with the transmissionassembly, the other end of the output connecting rod extends out of the cover plate and the bottom plate, and the transmission assembly drives the output connecting rod to rotate; and an arc-shaped slide rail and a vertical slide rail are mounted on the inner side of the bottom plate, and a first limiting stop dog and a second limiting stop dog can be slidably mounted on the arc-shaped slide railand the vertical slide rail correspondingly. According to the modular joint, the structure is compact, length adjustment is flexible, the adaptability is good, the modular joint is suitable for patients to accept, and targeted training can be achieved.

Description

Technical field [0001] The invention relates to an exoskeleton robot, in particular to a modular joint for exoskeleton for lower limb rehabilitation training. Background technique [0002] As strokes, spinal cord injuries, brain injuries, brain tumors and other diseases or accidents have impaired their exercise capacity, more and more patients are suffering from hemiplegia or paraplegia, and they are showing a clear trend of younger age. More patients look forward to relying on rehabilitation training to alleviate their symptoms and improve their athletic ability. However, the existing rehabilitation treatment methods have certain drawbacks and cannot be effectively promoted and applied. For example, traditional artificial rehabilitation methods and physical rehabilitation methods have problems such as low efficiency, inaccurate movement control, difficulty in evaluating rehabilitation effects, large differences in rehabilitation effects, and high prices. Standing exoskeleton ro...

Problems solved by technology

More patients expect to rely on rehabilitation training to alleviate symptoms and improve exercise capacity, but the current rehabilitation methods have certain drawbacks and cannot be effectively promoted and applied

For example, the traditional artificial rehabilitation treatment methods and physical rehabilitation treatment methods have problems such as low efficiency, inaccurate movement control, difficulty in evaluating rehabilitation effects, large differences in rehabilitation effects, and high prices. Standing exoskeleton robots have been extensively studied, but there are also problems such as heavy equipment, complex wearing, poor adaptability and safety, poor patient acceptance and high price, and because hemiplegic or paraplegic patients often have impaired joint motion ability, through Systematic exoskeleton body is not targeted enough for rehabilitation training of disabled joints
