Flexible rehabilitation chair based on variable stiffness adjustment

Abstract

The invention provides a flexible rehabilitation chair based on variable stiffness adjustment. The flexible rehabilitation chair comprises a supporting base, a bent pipe framework, an edge covering shell and a deformation assembly. The upper end of the supporting base is fixedly connected with the bent pipe framework, and the movable filler is distributed in the axial direction of the hose and fills a cavity of the whole hose. In the deformation assembly, the fixed end of a hose is fixedly connected with a bent pipe framework through a fastening hoop, the first end of a first rotating shaft and the first end of a second rotating shaft penetrate through a first belt wheel and a third belt wheel to be fixedly connected with the driving end of the hose, and the second end of the first rotating shaft penetrates through the center of the second belt wheel to be suspended out. The second end of the second rotating shaft penetrates through the center of the fourth belt wheel and is connected with a servo motor through a worm gear reducer. The flexible pipe is twisted, the internal space of the flexible pipe is compressed, the mobility of the filler is reduced, the rigidity change within a certain range is achieved, the twisting angle is adjusted according to the morphological characteristic curve and the weight in the use requirement, and the excellent supporting effect can be provided.

Description

technical field [0001] The invention relates to the field of medical rehabilitation, in particular to a flexible rehabilitation chair based on variable stiffness adjustment. Background technique [0002] Medical rehabilitation equipment can effectively improve the effect of postoperative rehabilitation. The market scale of the rehabilitation medical industry is large, and the demand for rehabilitation products is increasing rapidly. Therefore, medical rehabilitation equipment has gradually become a current research hotspot. As a new product of medical rehabilitation equipment, the medical rehabilitation chair can be widely used in orthopedic rehabilitation, traditional Chinese medicine physiotherapy, postpartum rehabilitation, spinal cord injury rehabilitation, and sports injury rehabilitation and other special disease fields. Variable stiffness technology relies on changing the different states and properties of materials and structures to achieve changes in stiffness withi...
