Forearm adaptive mechanism for centre drive upper limb rehabilitation robot

Abstract

The invention discloses a forearm adaptive mechanism for a centre drive upper limb rehabilitation robot, and relates to the field of upper limb rehabilitation equipment. The forearm adaptive mechanismcomprises a nut disconnecting mechanism, an adjustable arm support mechanism and a forearm compensation mechanism; the nut disconnecting mechanism, the adjustable arm support mechanism and the forearm compensation mechanism are sequentially connected; the nut disconnecting mechanism includes an I-type nut and a type II nut, and the adjustable arm support mechanism includes an adjustment washer set, a U-shaped arm support, an arm support base, and a main shaft; the forearm compensation mechanism includes a positioning guide shaft, a threaded cylindrical pin, and an I-shaped bushing. The technical solution disclosed by the invention can adapt to individual differences of different patients, and improve the comfort of a patient during the rehabilitation process and the acceptability of the patient to the upper limb rehabilitation robot equipment.

Description

technical field [0001] The invention relates to the field of upper limb rehabilitation equipment, in particular to a forearm self-adaptive mechanism for a centrally driven upper limb rehabilitation robot. Background technique [0002] With the aging of the global population and the increasing number of patients with neurological and musculoskeletal diseases, the demand for upper limb rehabilitation is also growing rapidly. The health care work for the elderly and patients is gradually being replaced by upper limb rehabilitation robots. When performing upper limb rehabilitation training, traditional upper limb rehabilitation robots cannot satisfy the slight rotation of the forearm during elbow flexion / extension training. At the same time, the fixed device designed on the forearm will cause patients to feel slight discomfort during training. [0003] The adaptability of machine equipment plays a vital role in the development of human-computer interaction machines. Traditional ...

[0002] With the aging of the global population and the increasing number of patients with neurological and musculoskeletal diseases, the demand for upper limb rehabilitation is also growing rapidly. The health care work for the elderly and patients is gradually being replaced by upper limb rehabilitation robots. When performing upper limb rehabilitation training, traditional upper limb rehabilitation robots cannot satisfy the slight rotation of the forearm during elbow flexion / extension training. At the same time, the fixed device designed on the forearm will cause patients to feel slight discomfort during training.

[0003] The adaptability of machine equipment plays a vital role in the development of human-computer interaction machines. Traditional research increases the difficulty in structural design of adaptive mechanisms, and the use of forearm parts in the process of upper limb rehabilitation training The rate is not high, so traditional research is difficult to meet the requirements, and traditional rehabilitation treatment does not pay much attention to the adaptability research of human-computer interaction, based on the current problems
