Lower limb active exoskeleton for earth surface weightlessness training

Abstract

The invention discloses a lower limb active exoskeleton for earth surface weightlessness training. The lower limb active exoskeleton comprises a tibia connecting rod, a femur connecting rod and a solepedal for fixing a foot, one end of the tibia connecting rod is connected with one end of the femur connecting rod through a first direct current servo motor, the other end of the femur connecting rod is connected with one end of an auxiliary support connection connecting rod through a second direct current servo motor, a tibia sensing module forming a C-shaped structure is arranged on the tibiaconnecting rod, a femur sensing module forming a C-shaped structure is arranged on the femur connecting rod, the sole pedal is connected with the tibia connecting rod through a rotating shaft, and thetibia sensing module and the femur sensing module are used for cooperating with a binding belt to correspondingly connect the tibia connecting rod and the femur connecting rod to a thigh and a shankof a human body. According to the lower limb active exoskeleton for earth surface weightlessness training, the sizes and shapes of the exoskeleton connecting rods and sensors can be designed accordingto the body shapes of different trainees, and high universal applicability is achieved.

Description

technical field [0001] The invention relates to the technical field, in particular to an active exoskeleton for ground weightlessness training lower limbs. Background technique [0002] When people are on the earth, they will be subjected to the gravitational effect on the ball, which is the gravitational effect. When astronauts work in outer space, they will be in a state of weightlessness or low gravity, so in order to achieve efficient operations and other physiological activities in this state, it is necessary to carry out systematic weightlessness training for astronauts. [0003] Astronauts undergo low-gravity training on the Earth's surface before operating in outer space. The surface training methods commonly used by scientific research institutions around the world include high-altitude free fall method, water buoyancy simulation method, etc., but they are all limited by cost, time or space. Contents of the invention [0004] The purpose of the present invention...
