The invention relates to the technical field of exoskeleton joint assisting equipment, in particular to a wearable knee-joint. The wearable knee-joint comprises a fixing part and a rotating part. Thefixing part comprises a first magnetic shielding disc and a magnet exciting coil, and a plurality of first magnetic conductive bushings connected each other in a sleeving manner are arranged on a surface of the first magnetic shielding disc. The rotating part comprises a second magnetic shielding disc, the second magnetic shielding disc and the first magnetic shielding disc are opposite and are coaxially and rotatably connected, a plurality of second magnetic conductive bushings connected each other in a sleeving manner are arranged on the surface of the second magnetic shielding disc, each magnetic conductive bushing is inserted between adjacent two first magnetic conductive bushings and a gap exists between two second magnetic conductive bushings, the first magnetic shielding disc, the second magnetic shielding disc, the first magnetic conductive bushings and the second magnetic conductive bushings form a working chamber filled with a magnetorheological fluid, and the magnet excitingcoil generates a magnetic field and is acted to the magnetorheological fluid. By arranging the bushings, the effective action area of the magnetorheological fluid can be increased, so that the damping force generated by the magnetorheological fluid is increased. The wearable knee-joint provided by the invention is simpler and more compact in structure and easy to assemble, so that the cost of thewearable knee-joint is lowered.
Description
technical field [0001] The invention relates to the technical field of exoskeleton joint auxiliary equipment, in particular to a wearable knee joint. Background technique [0002] As an important device to assist the user's knee joint movement, the wearable knee joint is more and more widely used in daily life. Among them, the passive wearable knee joint can protect the user's knee joint from damage when it is subjected to a large impact force. damage. [0003] Most of the existing passive wearable knee joint devices use a rod structure or a disc structure with magnetorheological fluid to provide damping force. In the rod structure, the amount of magnetorheological fluid used is limited and the active area is small, so the resulting damping The force is small and cannot provide sufficient protection for the user's knee joints. Although the multi-disc structure increases the area of action of the magneto-rheological fluid and provides greater damping force, the multi-disk ...
