Title:
ROTARY BUFFERING POWER-ASSISTED MECHANISM AND EXOSKELETON ANKLE-JOINT-BUFFERING POWER-ASSISTED DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/062706
Kind Code:
A1
Abstract:
Provided are a rotary buffering power-assisted mechanism and an exoskeleton ankle-joint-buffering power-assisted device. The rotary buffering power-assisted mechanism comprises a rotary external expansion assembly, an elastic reset member and an inner supporting heterogeneous component, wherein the rotary external expansion assembly comprises a first rotary member and a second rotary member, an external expansion cabin being defined by the first rotary member and the second rotary member; the elastic reset member is connected to free ends of the first rotary member and the second rotary member; and the inner supporting heterogeneous component is rotatably arranged in the external expandable cabin. When an external force drives the inner supporting heterogeneous component to rotate in the external expandable cabin, the inner supporting heterogeneous component exerts a force to do work to achieve conversion of elastic potential energy for storage, the functions of buffering and damping force are achieved in the storage process, and after the external force is finished, the elastic potential energy is released and converted into kinetic energy to help the free ends of the two rotary members approach each other, and a power assistance function is achieved.
