Lower limb assistance exoskeleton seat capable of being adjusted at multiple angles

Abstract

The invention relates to the field of lower limb assistance exoskeletons, and particularly provides a lower limb assistance exoskeleton seat capable of being adjusted at multiple angles. The lower limb assistance exoskeleton seat is composed of a waist fixator and two supporting legs. Each supporting leg comprises a shank structure, a thigh structure, an internal movement assembly and a leg fixator. One end of each shank rod is connected to one end of a corresponding thigh shell, one end of each bearing rod is connected to the middle of the corresponding shank rod, and the other end of each bearing rod is connected with a shock absorber. The shock absorbers do linear movement in cavities, the cavities are embedded in the thigh shells, and the shank rods, the bearing rods and the shock absorbers jointly form a crank sliding block mechanism. The cavities are provided with clamping groove holes, adjusting buckles do linear movement in the cavities, and the adjusting buckles can be manually fixed to different positions in the cavities. The adjusting buckles can limit the movement distance of the shock absorbers, and therefore the rotating angles of the shank rods and the thigh shells are limited. The lower limb assistance exoskeleton can be adjusted at multiple angles so as to meet the requirements of a wearer for different sitting postures, and normal walking of the wearer is not affected after the wearer wears the lower limb assistance exoskeleton.

Description

technical field [0001] The invention relates to the field of lower limb power-assisted exoskeleton, and in particular provides a wearable seat exoskeleton based on human body weight support. Background technique [0002] Many jobs in the society require people to engage in knee-bending movements for a long time. Some need to keep standing for a long time, and some need to keep squatting for a long time, such as workshop workers, medical staff performing operations, etc. Many working environments do not allow, or do not satisfy The condition of the seat. On the one hand, when the human body maintains a standing or squatting position for a long time, the muscles of the body are easily fatigued, which affects work efficiency. On the other hand, working in this working environment for a long time will cause huge damage to the human muscles and joints, causing occupational diseases. [0003] The development of supporting exoskeletons provides a good choice for such workers. Usin...

AI Technical Summary

Problems solved by technology

At present, there are many deficiencies in the supporting exoskeleton in this field. For example, the patent CN109330257A discloses a wearable exoskeleton seat, which includes thigh structural parts and calf structural parts. The belt design needs to be optimized. When the human body wears it, the center of gravity is on the back, and it is easy to fall backwards.
