  • Patent number: 11754153
    Abstract: The present invention discloses a distributed active/passive hybrid cable drive system, including a direct current motor, a magnetorheological actuator module, and a drive gear set. The direct current motor provides power for the system, the magnetorheological actuator adjusts output, a cable is driven to move by using a reel fixedly connected to an output shaft, the power is transmitted to a tail end by using the cable along a Bowden cable, and the tail end is connected to a controlled object, to implement control. The distributed active/passive hybrid cable drive system can implement controllable force output with large torque, small inertia, and high bandwidth, and has a small volume, high efficiency, and low costs compared with a pure motor drive system.

  • Publication number: 20220110815
    Abstract: A rope-driven soft hand function rehabilitation device includes four finger exoskeleton mechanisms, a thumb exoskeleton mechanism, and a soft rubber glove. An index-finger exoskeleton mechanism includes an index-finger distal phalanx loop, an index-finger middle phalanx loop, and an index-finger proximal phalanx loop which are mutually connected via a hinge structure. The thumb exoskeleton mechanism includes a thumb proximal phalanx loop and a thumb distal phalanx loop which are connected via a hinge structure. The rope is fastened to the hand function rehabilitation device via an aluminum sleeve which prevents the rope from slipping off during finger flexion/extension and abduction/adduction when the fingers are pulled by the rope at the palm and the hand back.
