Height-adjustable exoskeleton seat

Abstract

The invention belongs to the field of exoskeleton related technologies, and discloses a height-adjustable exoskeleton seat. The exoskeleton seat comprises a thigh and shank structure assembly and a sitting posture supporting assembly, wherein the thigh and shank structure assembly comprises a thigh structure assembly and a shank structure assembly which are connected rotatably; the length of the thigh structure assembly is changed by movement, the length of the shank structure assembly is changed by movement, and therefore, the height of the exoskeleton seat is adjusted; the sitting posture supporting assembly comprises a slide way baffle connected to the thigh structure assembly, an adjusting slider which is slidably connected to the slide way baffle, an upper supporting rod which is rotatably connected to the adjusting slider, a lower piston rod which is rotatably connected to the upper supporting rod and a supporting cylinder which is connected to the lower piston rod and the shankstructure assembly; and the supporting cylinder is used for driving the lower piston rod to move so as to drive the adjusting slider to slide along the slide way baffle, and thus, the sitting postureheight of the exoskeleton seat is adjusted. The height-adjustable exoskeleton seat is high in adaptability, 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 a height-adjustable exoskeleton seat. Background technique [0002] At this stage, employees in many industries often need to work while standing, bending over, or kneeling, but the working conditions and environment do not allow chairs to be placed, and long-term work often brings fatigue to the back and legs and discomfort, and there are certain safety hazards in working under the condition of physical discomfort, and it may cause occupational diseases in the long run. 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, the patent CN201710709306 discloses a cylinder-supported exoskeleton se...

Problems solved by technology

[0003] At present, those skilled in the art have done some research. For example, the patent CN201710709306 discloses a cylinder-supported exoskeleton seat, which uses a gas spring as a supporting structure when sitting, so that the exoskeleton seat can be used in various sitting positions. The height provides support, but due to the principle of the air spring’s principle of moving under force and returning to the limit position without force when the switch valve is opened, the exoskel
