Electric waist auxiliary exoskeleton

Abstract

The invention provides an electric waist auxiliary exoskeleton. The electric waist auxiliary exoskeleton comprises a back plate (1), shoulder straps (2), a driving actuating device (3), thigh sleeves(4), a left thigh connecting rod (5) and a right thigh connecting rod (6), wherein the upper end of the back plate (1) is connected with the shoulder straps (2), the lower end of the back plate (1) isconnected with the driving actuating device (3), two sides of the driving actuating device (3) are connected with the left thigh connecting rod (5) and the right thigh connecting rod (6), and the thigh sleeves (4) are arranged on the left thigh connecting rod (5) and the right thigh connecting rod (6). The electric waist auxiliary exoskeleton is simple and reasonable in structure, small, exquisite and light, the electric waist auxiliary exoskeleton is worn through the shoulder straps and the thigh sleeves, after wearing, the driving actuating device is located on the waist and can assist thewaist in bending down and stretching, a slider, a hip flexion curve and a hip extension line are adopted, auxiliary force control is executed through a series elastic actuation method, and stooping and squatting actions of a wearer are supported.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electric waist assisting exoskeleton. Background technique [0002] Currently, many workers are suffering from musculoskeletal disorders caused by repetitive motion industrial tasks, which can negatively affect the workers' daily life, one of the representative symptoms is low back pain, especially in construction, transportation, storage, human health and In the field of social work activities, the incidence of back disease is higher. Exoskeleton technology is considered to be an effective solution to prevent musculoskeletal diseases, but traditional lumbar-assisted exoskeletons are uncomfortable to wear due to their heavy weight and insufficient torque transmission, and most lumbar-assisted exoskeletons have long backs and hard materials, which interfere The wearer's natural lumbar movement. [0003] Traditional active waist-assisted exoskeletons usually use motors...

Problems solved by technology

However, the speed of the gas spring driving mechanism is easy to change, it is difficult to control accurately, and the low temperature characteristics are poor. Due to the lack of external energy in the system, the power output of the system is relatively small, and it cannot be adjusted in real time according to changes in external loads.
