Abstract

The invention provides a personalized wearable rehabilitation mechanical arm device. The device comprises a shoulder structure, an elbow structure and a wrist structure, the shoulder structure can rotate around a first direction, a second direction and a third direction respectively, the elbow structure comprises an elbow driving unit, an elbow driving rope set, a first rotating plate, a second rotating plate and an elbow shell set, the elbow driving unit is arranged on the shoulder structure, the elbow driving unit is in driving connection with the first rotating plate and the second rotatingplate through the elbow driving rope set so as to drive the first rotating plate and the second rotating plate to rotate relatively, the wrist structure comprises a wrist driving unit, a wrist driving rope set, a wrist rotating disc and a wrist shell set, the wrist driving unit is arranged on the shoulder structure, and the wrist driving unit is in driving connection with the wrist rotating discthrough the wrist driving rope set so as to drive the wrist rotating disc to rotate relative to the wrist shell set. The technical scheme can solve the technical problems that rehabilitation mechanical arms in the prior art are large in size, complex in structure and low in motion precision.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a personalized wearable rehabilitation mechanical arm device. Background technique [0002] In the prior art, most of the exoskeleton-type upper limb rehabilitation mechanical arms are general-purpose, and the size is adjusted according to the needs of different patients during rehabilitation training. However, this mechanical arm cannot fully meet the arm size of each patient. When the lengths are equal, the position of the joint is often determined according to the patient's own feelings. There will inevitably be a certain degree of error in the coordinates and angles, which will eventually lead to a decrease in motion accuracy and affect the effect of rehabilitation training. During the rehabilitation training process, the arm may slip relative to the mechanism and cause danger. The fragility of the stroke patient itself requires the designed rehabilitation equipment to have a ...
