The invention discloses a bionic stretch-draw integral multi-degree-of-freedom self-supporting flexible ankle joint wearing power assisting device, which relates to the field of walking assisting and power assisting equipment, and comprises a foot wearing assembly, a leg fixing assembly, passive flexible rope assemblies and a flexible stranded wire driving assembly; the passive flexible rope assemblies are connected to the left side and the right side between the foot wearing assembly and the leg fixing assembly, and the flexible stranded wire driving assemblies are connected to the front side and the rear side between the foot wearing assembly and the leg fixing assembly. The foot wearing assembly, the leg fixing assembly, the passive flexible rope assemblies and the flexible stranded wire driving assembly jointly form an overall tensioning mechanism which can adjust the change of the relative position and posture between the foot and the leg and has the self-supporting performance. According to the invention, the overall tensioning mechanism has the characteristics of flexibility, light weight and reconfigurability, has a self-supporting characteristic, can provide effective supporting force for a wearer and reduce pressure borne by ankle joints during walking, and the stranded wire driving assembly can realize light-weight and flexible driving.
Description
technical field [0001] The invention relates to the technical field of walking aids and power-assisted equipment, and more specifically relates to the technical field of bionic tensegrity multi-degree-of-freedom self-supporting flexible ankle joints. Background technique [0002] The ankle joint is an important joint that connects the legs and feet, and is also a key part that provides support and movement for the body during walking. Because the ankle joint is the most frequently used joint in daily activities, it is more prone to injury than other joints. [0003] Existing wearable power assist devices can be divided into rigid wearable devices and flexible wearable devices. Among them, rigid devices are the most widely researched type of devices, and in practical applications, rigid wearable devices are mostly used. Rigid wearable devices use rigid components such as rods to simulate the skeletal system of the human body. Multiple sets of rigid components form a system ...
