Abstract

The invention requests protection of a wearable forearm active rehabilitation training exoskeleton device with myoelectric perception and belongs to robot field. The wearable forearm active rehabilitation training exoskeleton device consists of an exoskeleton support, a forearm rotation mechanism, an elbow flexion-extension mechanism, a driving motor and a myoelectric signal acquisition device, and can achieve the active rehabilitation training with two degrees of freedom for elbow flexion-extension and arm rotation. A large forearm support is easier to wear with a semi-open structure, and themyoelectric signal acquisition device is embedded in a key position of lining to collect arm myoelectric signals during the process of the rehabilitation training, and then motor movements of each joint can be adjusted according to the muscle tension, improving the security and efficiency of training. The forearm rotation mechanism adopts two sets of motor-bevel gear transmission, achieving forearm flexion-extension movements through synchronous coordinated movements of two motors. The forearm rotation mechanism adopts the driving mode of wire, and the forearm rotation angle is 180 degrees. The wearable forearm active rehabilitation training exoskeleton device with the myoelectric perception is more convenient, safer and more effective in rehabilitation training and can be widely used inhospitals, communities and families.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a wearable forearm active rehabilitation training exoskeleton device with myoelectric sensing, specifically an active rehabilitation training designed for the two joints of forearm rotation and elbow flexion and extension exoskeleton device. Background technique [0002] The functional disability of the upper arm of the human body caused by diseases such as stroke will have a great impact on the lives of patients. Timely and effective rehabilitation training can help patients rebuild upper arm motor function and improve the quality of life of patients. Designing rehabilitation robots for the needs of human upper arm rehabilitation training has become a hot topic in the field of rehabilitation medicine in recent years. In traditional artificial physical therapy, therapists are labor-intensive and require highly skilled skills. Rehabilitation robots are designed to us...
