Parallel-connection ectoskeleton knee joint

Abstract

The invention relates to a parallel-connection ectoskeleton knee joint in the technical field of rehabilitation engineering. The parallel-connection ectoskeleton knee joint is characterized by comprising a first thigh support frame, a second thigh support frame, a first connecting plate, a second connecting plate, a thigh coat and a leg coat, wherein the first thigh support frame and the first connecting plate are fixedly connected; the second thigh support frame and the second connecting plate are fixedly connected; the thigh coat is fixed on the first thigh support frame and the second thighsupport frame; the leg coat is located below the thigh coat. The parallel ectoskeleton knee joint further comprises a first movement branched chain and a second movement branched chain, wherein the first movement branched chain is provided with a first connection rod; the second movement branched chain is provided with a second connection rod; the first connection rod and the second connection rod are movably connected via a turning pair; both ends of the first connecting plate and both ends of the second connecting plate are respectively fixed on the first movement branched chain and the second movement branched chain; and the leg coat and the turning pair are fixedly connected. The invention has good rigidity, high bearing capacity and high bio-imitability and can satisfy the requirements of users with different sizes of the knee joints.

Description

technical field [0001] The invention relates to a knee joint in the technical field of rehabilitation engineering, in particular to a parallel exoskeleton knee joint. Background technique [0002] Every year, a large number of people in the world are physically disabled or paralyzed due to accidents or diseases, and lose their normal mobility. Clinical medical experience shows that correct and scientific rehabilitation training can play a very important role in the recovery and improvement of limb motor function. At present, physical rehabilitation training is mainly realized by professional nurses artificially simulating the joint movement of patients' limbs. This method has high requirements on the quality of professional nurses, and the labor intensity of professional nurses is relatively high, with high medical expenses and poor flexibility. . In order to solve this problem, a variety of active rehabilitation equipment has been designed and developed. The exoskeleton r...

Problems solved by technology

This technology is composed of lumbar support, hip four-bar mechanism, knee four-bar mechanism, ankle four-bar mechanism and plantar support in series. Although its skeleton can assist or enhance people's walking ability, it has obvious deficiencies and limitations. Defects: Once the size of the linkage mechanism is determined, its motion track is also determined, and it needs to be customized for different users; The structure of the rod mechanism is more complicated
