A passive lower extremity exoskeleton device for energy transfer in the human body

Abstract

The invention discloses a passive lower limb exoskeleton device for achieving human body energy migration. The passive lower limb exoskeleton device comprises a sole pressure sensor assembly arrangedon an insole, a lower limb connecting assembly is arranged at the back end of the insole, a plurality of control switch assemblies in signal connection with the sole pressure sensor assembly are hinged to the back side of the lower limb connecting assembly, and a bionic spring assembly is in sliding connection to each control switch assembly and is matched with the control switch assembly in a clamped manner to achieve limitation; and sole pressure sensors are used for collecting signals, the signals are used for controlling switches, then the stretching / contracting states of the bionic springassemblies are controlled, energy generated when the knee joint does negative work in the human body walking process is converted into elastic potential energy to be collected and stored, and the energy is transferred to the ankle joint in the standing phase later period, and energy dissipation of muscle during positive work doing of the ankle joint is reduced. By means of the passive lower limbexoskeleton device, external connection energy resources are avoided, the structure is simple, the mass is small, and wearing is convenient.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation physical therapy auxiliary equipment, and in particular relates to a passive lower limb exoskeleton device for realizing energy transfer of a human body. Background technique [0002] As a new type of wearable human-machine integration system, exoskeleton is mainly used in military operations and rehabilitation medical fields. In the military field, exoskeletons can improve the strength, speed and endurance of soldiers, thereby improving individual combat capabilities; in the field of rehabilitation medicine, exoskeletons can assist patients such as stroke, paraplegia or osteoarthritis to walk, thereby restoring or partially restoring their life activities . [0003] At present, exoskeletons at home and abroad are mainly divided into active exoskeletons and passive exoskeletons. Active exoskeletons are mainly composed of energy devices, drive systems, control systems and actuators. The dri...
