Foldable exoskeleton wheelchair integrated motion assisted robot

Abstract

The invention discloses a foldable exoskeleton wheelchair integrated motion assisted robot. The robot comprises two foot pedals, two shank rods, two thigh rods and two waist rods which are bilaterally symmetry. The drive motors of the shank rods drive rear wheel shafts, small gears are fixedly connected to the rear wheel shafts, the small gears mesh with big gears, the big gears are fixedly installed at the outer end of knee joints, bottom rods are arranged at the outer side of the big gears, the bottom rods are rotatably connected to the rear wheel shafts, the shank rods are arranged at the inner side of the bottom rods, small connecting rods are arranged between the bottom rods and the shank rods, and the lower end of the bottom rods and the lower end of the shank rods are connected through ankle joints; thigh rod sliding blocks and shank rod sliding blocks are connected through big connecting rods which are located at the outer side of the thigh rod sliding blocks and the shank rod sliding blocks, front wheels and rear wheels are installed on the bottom rods, universal wheels are arranged in front of the front wheels, a back plate is connected between the two waist rods, and a flexible seat cushion is connected between the two thigh rods. According to the foldable exoskeleton wheelchair integrated motion assisted robot, a fast motion function, an assisted standing function and an assisted walking function of a wheelchair are integrated.

Description

technical field [0001] The invention relates to a mobility assistance robot, in particular to a foldable exoskeleton wheelchair integrated mobility assistance robot. Background technique [0002] With the development of society, our country has stepped into an aging society. By the end of 2014, my country's elderly population over the age of 60 had reached 212 million, accounting for 15.5% of the total population. Moreover, most of the elderly have problems such as insufficient joint strength and inconvenient legs and feet, and they need people to take care of them in their daily life. In addition, there are a relatively large proportion of patients with cerebrovascular diseases in our country. They are usually accompanied by hemiplegia and paraplegia, which seriously affect the movement of lower limbs. Medical research shows that after the condition of cerebrovascular patients is stable, the damaged nervous system will be repaired automatically, but the natural recovery p...
