Abstract
A variable stiffness hand exoskeleton device based on antagonistic driving, includes a power mechanism, a support base, a spring-link composite transmission mechanism, and a distal finger sleeve connected to a power output end of the spring-link composite transmission mechanism for fingers. The power mechanism drives the fingers to perform rotational movements through the spring-link composite transmission mechanism. The distal finger sleeve is fixed to a distal joint periphery of a finger joint using a first elastic adjustment band, and provides force feedback to an end of the finger joint under driving force of a link structure. An inner surface of the support base is contoured to match a palm, and a back of the support base is provided with a rotary support seat and a motor fixing seat. A motor group of the power mechanism is mounted on the motor fixing seat.
