Passive elbow joint assisting exoskeleton capable of storing energy

Abstract

The invention discloses a passive elbow joint assisting exoskeleton capable of storing energy, and belongs to the field of object processing systems. The passive elbow joint assisting exoskeleton comprises an upper arm unit, a lower arm unit and an elbow joint unit located between the upper arm unit and the lower arm unit, wherein the upper arm unit is rotationally connected with the lower arm unit; the elbow joint unit comprises an anti-gravity mechanism, a coil spring mechanism and a lower arm unit self-locking mechanism; the anti-gravity mechanism generates balance moment to eliminate the influence of the arm weight of a user and the weight of the device on the elbow joint; the lower arm unit self-locking mechanism is used for locking / releasing the lower arm unit at any specified rotation angle; and the coil spring mechanism is used for obtaining and storing the motion energy of rotating and swinging of the arm of the user and releasing the motion energy in time. The lifting capacity of the elbow of a person is enhanced by utilizing the energy of the person and the mechanical advantages of the device, so that the problem that an existing passive exoskeleton lacks the capacity ofcollecting the kinetic energy of movement of human body parts is solved, and muscle fatigue and injury of the user in the material carrying / lifting process are avoided.

Description

technical field [0001] The invention belongs to the field of object processing systems, in particular to the field of exoskeletons that can be worn on elbow joints and help the elbow joints to lift or carry loads, and in particular relate to a passive energy-storable elbow joint power-assisted exoskeleton. Background technique [0002] Lifting / carrying heavy objects by hand may cause fatigue or injury to the associated muscles. According to statistics, muscle injuries account for about 30% of all injuries and diseases in the workplace. To prevent these injuries, general strategies include educating workers on proper lifting techniques, requiring several workers to share lifting tasks, and using mechanical lifting equipment as much as possible. Since most mechanical lifting equipment is slower than manual handling, less readily available, and often limited by the environment, when loads are considered to be within a person's lifting capacity, people often tend to do it direc...
