  • Unpowered wearable walking assistance knee equipment with gait self-adaptivity
    Patent number: 11633319
    Abstract: The present disclosure discloses an unpowered wearable walking assistance knee equipment with gait self-adaptivity comprising a left foot power output assembly, a right foot power output assembly, a left leg knee joint assistance execution assembly, a right leg knee joint assistance execution assembly and a driving force transmission device. The equipment of the present disclosure is based on lever principle and crank block structure principle and adopts an operation mode of combining ipsilateral parallel driving input and different sides cross driving input.

  • Soft knee exoskeleton driven by negative-pressure linear actuator
    Patent number: 11497672
    Abstract: The present invention discloses a soft knee exoskeleton driven by a negative-pressure linear actuator, including: an exoskeleton controller, a left leg knee joint soft actuator, a right leg knee joint soft actuator and the like. The soft knee exoskeleton mainly uses a miniature vacuum negative pressure pump as an air pressure power source. A DSP embedded control system performs real-time processing on the data, such as a muscle force, a knee joint angle and a human-machine interaction force, detected by a sensing system, estimates a human-machine cooperation state, and performs real-time control on the switching of the negative pressure flow and an air channel of the miniature vacuum negative pressure pump.
