Abstract

The invention discloses a wheelchair device which can help a patient to perform lower limb rehabilitation training, can achieve adjustment of three postures, and can be applied to the field of medical rehabilitation apparatuses. The lower limb rehabilitation wheelchair includes a flexible adjustment mechanism arranged on a chair back, a three-posture adjustment mechanism which is arranged on a base and is fixedly connected to the chair back, a leg mechanism which is fixedly connected to a three-posture adjustment frame, and a leg auxiliary support system. A step function section is driven by a push rod, and bionics steps of human body natural walking are simulated through a preset program to achieve a training effect. The leg auxiliary support system can support legs in a seat posture through coordination of bevel gears, screw rods and support plates, and can automatically move backward in a stand posture and will not affect the legs. The chair back adjustment mechanism has the function of multi-dimension automatic flexible adjustment, and can adjust the chair back according to the demands of a user. The three-posture adjustment mechanism can adjust a stand posture, a seat posture and a lie posture. The lower limb rehabilitation wheelchair can provide various posture training manners.

Description

technical field [0001] The invention relates to the field of intelligent wheelchairs, in particular to a three-state adjustable lower limb rehabilitation wheelchair. Background technique [0002] Population aging, natural disasters and various accidents have caused a large number of vulnerable groups to need care. The recovery treatment of patients with inconvenient lower limbs often requires a long treatment cycle, and the recovery effect is not ideal. Exercise therapy is a common method of lower extremity rehabilitation. Traditional rehabilitation training involves the therapist manually driving the patient's lower limbs to perform exercise training, which is highly subjective, time-consuming and laborious, and the effect is not ideal. As an automated, precise, and intelligent medical device, lower limb rehabilitation institutions have strong advantages in providing continuous and quantitative rehabilitation training, which can effectively make up for the shortcomings of ...
