Embodiment 1
[0054] This embodiment proposes a spring energy storage and quick unloading lower limb power-assisted exoskeleton, its structure is as follows Figure 4 , including a thigh mount 1 , an upper adapter part 2 , an air support part 3 , a middle adapter part 4 , a link part 5 , a lower adapter part 6 and a shoe part 7 .
[0055] The specific assembly relationship of the upper adapter part 2 is as follows: Figure 5 , the main function of the adapter part is to connect the thigh mounting seat 1 and the air support part 3, so that the air support part 3 can rotate around an axis of the thigh mounting seat 1. In addition to this function, the upper adapter part 2 also provides the air support part 3 top support. The upper adapter part 2 is composed of a U-shaped joint 201, a first rotating bearing 202, a first nut 203, a first retaining ring 204, a first bearing seat 205, a first sleeve 206, a first bolt 207 and a first screw 208 , wherein, the hole below the U-shaped joint 201 is ...

The invention relates to an air-supported passive lower limb power-assisted exoskeleton device, comprising a thigh mounting seat, an upper transfer part, an air support part tending to elongate, a middle transfer part, a connecting rod part, a lower transfer part and a shoe part , wherein, the upper transfer part is respectively connected to the upper part of the thigh mounting seat and the air support part, and allows the air support part to rotate relatively around the thigh mounting seat, and the middle transfer part is respectively connected to the air support part and the connecting rod components, and allow relative rotation between the top of the link component and the air support component, and the lower transition component connects the link component and the shoe component respectively, and enables the link component to rotate relatively around the shoe component. Compared with the prior art, the invention has the advantages of compact structure, low manufacturing and maintenance costs, and realizes power assist through passive elements without external energy input.
Description
technical field [0001] The invention belongs to the field of power-assisted bones, and relates to an air-supported passive lower limb power-assisted exoskeleton device. Background technique [0002] Arthritis and muscle damage caused by joint disease or excessive load exercise make people's lower limbs lose their original ability to move. The aging problem of the human body also leads to a series of lower limb inconveniences. Exoskeleton can improve these problems. There are some commercialized exoskeletons on the market. Most of them adopt active power-assisted solutions, which input energy to the human body through motors to support the human body. However, the problem with active exoskeletons is that they are often bulky, require complex control algorithms, and require high manufacturing and maintenance costs. Passive exoskeletons can avoid this problem, and the compact design can make the equipment small and reduce the cost, which is suitable for daily use. [0003] At...
