Passive exoskeleton device based on energy cross-joint transfer

Abstract

The invention belongs to the technical field related to exoskeletons, and discloses a passive exoskeleton device based on energy cross-joint transfer. The exoskeleton device comprises a waist wearing assembly, hip joint energy storage assemblies, ankle joint assisting assemblies and clutch assemblies, the waist wearing assembly is worn on the waist, the hip joint energy storage assemblies are worn on the thighs, and the ankle joint assisting assemblies are worn on the ankle joints; the clutch assembly is used for enabling the exoskeleton device to be switched between an energy storage mode and a power assisting mode; when the exoskeleton is in an energy storage mode, the tension spring is stretched, and the elastic potential energy of the tension spring is stored; when the exoskeleton is in a power-assisted mode, the feet of a power-assisted object step on the ground, the thighs swing backwards, the trigger rope is straightened and drives the trigger block to move upwards, the tension spring retracts to drive the sliding block to move upwards, the pull force generated when the sliding block moves upwards is transmitted to the ankle joint power-assisted assembly, and then power assistance of the power-assisted object is achieved. According to the invention, the problem that electronic elements and circuit control are needed in the exoskeleton is solved.

Description

technical field [0001] The invention belongs to the related technical field of exoskeleton, and more specifically, relates to a passive exoskeleton device based on energy transfer across joints. Background technique [0002] During military training, field search and rescue, etc., people often need to walk long distances. However, walking consumes a lot of physical energy, and people's field activities are therefore limited, and even affect the execution of tasks. In order to improve walking efficiency, various exoskeleton designs have been proposed. Due to its heavy weight and severe restrictions on the human body, active exoskeletons are difficult to achieve the goal of reducing the consumption of metabolic energy for walking. The passive exoskeleton can be effectively embedded in the energy transfer circuit of the musculoskeletal system of the human lower limbs. With the help of the efficient energy conversion characteristics of the elastic elements, the metabolic energ...
