Waist power-assisted outer skeleton mechanism and power-assisted method thereof

Abstract

The invention relates to a waist power-assisted outer skeleton mechanism and a power-assisted method thereof. The mechanism comprises a front chest supporting unit and a bearing unit, the front chestsupporting unit comprises a chest plate, a carapace, two oxter supports and two hydraulic cylinder system assemblies, and the side faces of the lower portions of the chest plate and the carapace are connected together through the two oxter supports. The carapace, the chest plate and the oxter supports overall constitute a vest shape, and the connecting positions of the carapace, the chest plate and the oxter supports are connected through elastic connecting belts. The two hydraulic cylinder system assemblies are mounted on the front end face of the chest plate in a left-right symmetry mode, each hydraulic cylinder system assembly comprises an upper hinging support, a hydraulic cylinder and a lower hinging support, and the two ends of each hydraulic cylinder are provided with rod end ball bearings. The bearing unit comprises an artificial spine part and a back frame part, the back frame part is connected to the left portion and the right portion of the carapace, and the artificial spinepart is connected to the middle position of the carapace. The waist power-assisted outer skeleton mechanism can provide assisted power when people carry heavy objects and help people to save more labor when people bend down and get up during heavy object carrying.

Description

technical field [0001] The invention relates to the technical field of power-assisted exoskeleton robots, in particular to a waist power-assisted exoskeleton mechanism and a power-assisted method thereof. Background technique [0002] Diseases of the lower back in the current society, such as lumbar muscle strain, lumbar disc herniation, etc., are showing a trend of younger age, especially those who need to bend down for a long time or frequently for heavy physical labor, need a device to reduce the burden on the lower back and reduce the risk of lower back pain. The risk of back disease, so in order to strengthen the protection of workers' lumbar spine, it will be inevitable to introduce exoskeleton mechanism for lumbar spine protection, and the application potential is very huge. For example, the patent whose publication number is CN106821682A proposes a wearable waist assist device, which outputs torque at the hip joint through the cooperation of steering gear and torsion...
