Problems solved by technology

At present, there are more than 10 laboratories in the world engaged in the research of wearable walking aids, and most of them are used for the assistance of normal people or the rehabilitation of patients with lower limb dysfunction, and few are used to help paralyzed people stand up again. Research on walking devices
Moreover, most of the existing researches use motor direct drive or pneumatic, and the cost is also very expensive.
In addition, the existing powered walking aids do not have the function of abduction and adduction of the thigh, and the movements are stiff when walking, and the simulation and comfort are not good

Abstract

The invention relates to a line angle driving lower limb walking aid. The walking aid comprises bilaterally symmetrical waist support brackets, thigh support rods, shank support rods, feet support plates, first hip joint revolute pairs, second hip joint revolute pairs, knee joint revolute pairs, ankle joint revolute pairs, abduction and adduction driving mechanisms, flexion and extension driving mechanisms, thigh fastening straps and shank fastening straps. The walking aid has the following advantages: the walking aid has a scientific and reasonable structure design, can assist patients with paralysis of lower limbs to stand and walk, is stable in operation and reliable in support, is easy to produce and has low cost.

Description

technical field [0001] The invention relates to a walking aid, in particular to a walking aid for lower limbs driven by wire angles. Background technique [0002] Powered walking aids are the result of the combination of modern scientific and technological progress and the needs of human rehabilitation. The purpose is to research and develop various walking aids for the evaluation, diagnosis, recovery, walking compensation and nursing of paraplegics. At present, there are more than 10 laboratories in the world engaged in the research of wearable walking aids, and most of them are used for the assistance of normal people or the rehabilitation of patients with lower limb dysfunction, and few are used to help paralyzed people stand up again. The study of walking devices. And most of the existing researches use motor direct drive or pneumatic, and the cost is also very expensive. In addition, the existing powered walking aids do not have the function of abduction and adduction...
