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. The self-weight of the human body is utilized as a driving force during the walking process to enable the left foot power output assembly to provide the left leg knee joint assistance execution assembly with a pulling force for its stretching and to provide the right leg knee joint assistance execution assembly with a pulling force for its bending, and to enable the right foot power output assembly to provide the right leg knee joint assistance execution assembly with a pulling force for its stretching and to provide the left leg knee joint assistance execution assembly with a pulling force for its bending, so that a torque fo…
