Abstract

The invention provides a lower limb exoskeleton robot system based on human-machine terminal interaction, and relates to a lower limb exoskeleton robot. The system solves the problems of poor adhesionbetween the lower limb exoskeleton and the human body, uncomfortable wearing, inaccurate human-computer interaction information, poor man-machine following effect and inconspicuous power assisting effect caused by the prior lower limb exoskeleton. A low part of that back frame is symmetrically provided with two hip joint bracket, one end of the hip joint support is rotatably connected with the back frame 1 through an adduction and abduction shaft, the free end of each hip joint bracket is rotatably connected to the corresponding hip joint through an internal and external hip rotation axis, Each hip joint is connected with a corresponding thigh rod through a hip flexion and extension shaft, an inertia unit is arranged at the upper part of each thigh rod, the lower part of each thigh rod isconnected with the upper end of the corresponding calf rod through a knee joint, one end of a pneumatic spring is connected with a back frame, and the other end of the pneumatic spring is connected with a corresponding hip joint bracket. The invention is used for a lower limb exoskeleton robot.

Description

technical field [0001] The invention relates to a lower limb exoskeleton robot, in particular to a lower limb exoskeleton robot system based on human-machine terminal interaction. Background technique [0002] An exoskeleton robot is a wearable device that integrates various technologies such as sensing technology and control technology. In particular, a lower limb exoskeleton robot is an exoskeleton robot that is similar in structure to the lower limbs of a human body, and can help the wearer realize Assist walking, lower limb rehabilitation, up and down stairs and other actions. [0003] The lower extremity exoskeleton robot is mainly composed of hip joints, knee joints and ankle joints, with 15 degrees of freedom, including waist rotation, hip extension and flexion, hip abduction, hip internal and external rotation, knee extension and flexion, ankle extension and flexion, Ankle rotation, ankle inversion. [0004] At present, the existing lower extremity exoskeleton has ...
