A height-adjustable exoskeleton seat

Abstract

The invention belongs to the technical field of exoskeleton, and discloses a height-adjustable exoskeleton seat. The exoskeleton seat includes a thigh structure assembly and a sitting posture support assembly. The thigh structure assembly includes a thigh structure assembly that is rotatably connected and The calf structure assembly; the thigh structure assembly changes its own length by moving, and the calf structure assembly changes its own length by moving, thereby realizing the height adjustment of the exoskeleton seat; the sitting posture support assembly includes slideway baffles connected to the thigh structure assembly, The adjustment slider slidably connected to the slideway baffle, the upper support rod rotatably connected to the adjustment slider, the lower piston rod rotatably connected to the upper support rod, and the support cylinder connected to the lower piston rod and the lower leg structural components; The cylinder is used to drive the lower piston rod to move, and then drive the adjustment slider to slide along the slideway baffle, thereby realizing the adjustment of the sitting height of the exoskeleton seat. The invention has strong adaptability, high flexibility and simple 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 exoskeleton seat has certain resistance during the walking process of the person after wearing it, which affects the normal operation of the person. walk

Another example is the patent CN201710709304 which discloses a gear-positioned exoskeleton seat, which adjusts the height of the sitting posture through the positioning of the gear and rack. When people sit down and get up, they need to toggle the operating lever. For some emergency situations, they cannot get up in time. certain security risks
