Pose-adjustable outer skeleton chair

Abstract

The invention belongs to the technical field related to outer skeletons and discloses a pose-adjustable outer skeleton chair. The chair comprises a thigh structural assembly, a shank structural assembly and a pose supporting assembly. Two ends of the pose supporting assembly are separately connected to the thigh structural assembly and the shank structural assembly, and the thigh structural assembly and the shank structural assembly are rotatably connected; the thigh structural assembly moves in the length direction to adjust the length and the shank structural assembly also moves in the length direction to adjust the length; the pose supporting assembly comprises two working states: a locking state and a moving state. In the moving state, the pose supporting assembly slides to change thepose of the chair. The pose supporting assembly is driven by the thigh structural assembly or / and the shank structural assembly. The pose-adjustable outer skeleton chair disclosed by the invention isrelatively high in adaptability, relatively high in flexibility and simple in structure.

Description

technical field [0001] The invention belongs to the technical field related to exoskeleton, and more specifically relates to an exoskeleton seat with adjustable posture. Background technique [0002] At present, employees in many industries often need to work while standing, bending over, and knees. However, the working conditions and environment do not allow chairs to be placed. Long-term work often causes fatigue in the back and legs And discomfort, and there are certain safety hazards in working under the condition of physical fatigue and discomfort, and it may also cause occupational diseases for a long time. Among them, the appearance of exoskeleton seats can improve the ergonomic working environment, allow workers to maintain a correct posture for work, and at the same time prevent occupational diseases and avoid some safety problems. [0003] At present, those skilled in the art have done some research. For example, patent CN201710709306 discloses a cylinder-supporte...

AI Technical Summary

Problems solved by technology

[0003] At present, those skilled in the art have done some research. For example, patent CN201710709306 discloses a cylinder-supported exoskeleton seat, which uses a gas spring as a supporting structure when sitting, so that it can provide support at various sitting heights. , but due to the principle that the gas spring recovers to the limit position without force when the switch valve is opened

In addition, after the bone seat is worn, there is a certain resistance during the walking process of the person, which affects the normal walking of the person.
