Structure Design Of Exoskeleton Device Based On Virtual Reality

Nowadays,with the increasing incidence of cardiovascular and cerebrovascular diseases,especially due to cerebral artery infarction and rupture and bleeding,millions of disability sequelae have been lost,and the motor function of the limbs has been lost.How to provide a proper and effective means of rehabilitation for this huge limb dysfunction group is an important challenge for the vast numbers of scientific and technical workers and medical staff.The virtual reality technology to build out the humanization of the virtual scene can provide users with real world special effect can not be achieved,can make patients actively cooperate with treatment in the psychological sense,can effectively reduce the work intensity of rehabilitation nurses.The superiority of medical rehabilitation to make it more and more widely accepted,but its design and treatment there are also some problems,aiming at these situations,combined with virtual reality technology,selected the structural design of upper limb exoskeleton device for the reconstruction of the upper body flexibility,and puts forward a practical scheme.First of all,the paper summarizes the research and application status of virtual reality technology and exoskeleton robot at home and abroad.According to the present stage of medical rehabilitation situation,designed a set of upper limb exoskeleton rehabilitation system,according to the human body joint mechanical model,the exoskeleton robot with five degrees of freedom for shoulder rotation / flexion,rotation,elbow and wrist rotation and hand flexion / extension,and design the overall structure of upper limb exoskeleton rehabilitation robot.Secondly,according to the application requirements of the rehabilitation robot by comparing various drive,selection of light weight,high power,good flexibility,high safety of the pneumatic muscles as rehabilitation robot drive and pneumatic muscle of gas and its model and analyzed the characteristics of driving joint.Finally,by using the basic theory and method of mechanical design,the design of the pneumatic artificial muscle drive five degree of freedom upper limb exoskeleton rehabilitation robot,can realize the active and passive rehabilitation training activities,also conducted a preliminary analysis of the supply circuit design and control system.According to the current situation and the rehabilitation of patients with medical conditions,the use of virtual reality design theory,exercise therapy and psychological treatment combined,upper limb exoskeleton rehabilitation training robot designed to take a portable mechanism,has the characteristics of simple structure,small volume,light weight,low cost and good safety.The utility model can greatly improve the enthusiasm of the rehabilitation treatment of the patients,improve the effect of the rehabilitation treatment of the upper limb to a greater extent,and can carry out the upper limb rehabilitation training for the elderly and the disabled in the family or the hospital.
