Abstract

The invention relates to a seven-degree-of-freedom upper limb rehabilitation robot which comprises a shoulder joint assembly, an elbow joint assembly, a wrist joint assembly and a rack assembly, the shoulder joint assembly mainly achieves three-degree-of-freedom movement, namely protraction / retroflexion, abduction / adduction and spinning of a shoulder joint, the elbow joint assembly mainly achieves two-degree-of-freedom movement, namely flexion and extension and spinning of an elbow joint, and the wrist joint assembly mainly achieves two-degree-of-freedom movement, namely valgus / adduction and radial / ulnar flexion of a wrist joint. From the consideration of human body structure, the seven-degree-of-freedom upper limb rehabilitation robot is reasonable and compact in spatial layout, convenient to wear, large in movement range and flexible in degree of freedom, single joint movement and composite movement of the whole upper limb are conveniently achieved, active, assisted or passive control strategies can be adjusted according to the control requirements of different rehabilitation periods, and the training requirements of patients in different rehabilitation periods are met.

Description

technical field [0001] The invention relates to the technical field of rehabilitation equipment, in particular to a seven-degree-of-freedom upper limb rehabilitation robot. Background technique [0002] As the global population grows, the problem of population aging is becoming more and more prominent. Stroke, commonly known as "stroke", is a common disease among the elderly. It is an acute cerebrovascular disease that can cause persistent damage to the brain and nervous system. For the rehabilitation treatment of stroke patients, the traditional rehabilitation method mainly involves physical exercise training for patients by rehabilitation doctors. At present, patients are also treated by rehabilitation robots, but the humanization, intelligence and structural optimization of rehabilitation robots still need to be greatly improved. Therefore, it is of great practical significance to design a reasonable and reliable rehabilitation institution to improve the rehabilitation ...
