Problems solved by technology

[0005] The present invention provides a tensioned flexible ankle wearable booster device driven by twisted pairs. The booster introduces the twisted pair into the ankle booster mechanism to solve the problem of mass and size caused by the need for a large reduction ratio system when driven by a motor. The problem of being too large, with a special flexible joint, can reduce the discomfort caused by misalignment, so as to solve the problems mentioned in the above background technology

Abstract

The invention provides twisted-pair-driving-based tensioned flexible ankle joint wearing boosting equipment. The boosting equipment comprises a foot region supporting plate, a flexible joint made froma soft material and a rigid element, an ankle wearing assembly connected with the flexible joint and a twisted line driving part for driving an ankle joint to move, wherein the flexible joint is composed of a limiting rod fully encapsulated in the soft material and a rigid connecting member fully encapsulated in the soft material, and the twisted line driving part is composed of a motor, a gear transmission system and a twisted pair. According to the ankle joint boosting mechanism, two fine lines are driven to twist mutually through the motor so as to form a dual-spiral structure through pre-twisting, muscle-similar stretching and tensioning motions are achieved through tightness of twisting, and then, a wearer is assisted to walk. According to the boosting equipment, free motions in dorsal flexion, plantar flexion, intorsion and extorsion directions can be achieved through the purpose-made flexible joint, twisted-pair structures at two sides are driven by one motor to simultaneouslyachieve double-sided stretching and tensioning functions, and a safe protecting function for the ankle joint can be provided.

Description

technical field [0001] The invention relates to the field of walking aids, in particular to a stretchable and flexible wearable assisting device driven by a twisted pair. 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. Since the ankle joint is the most frequently used joint in daily activities, it is more prone to injury than other joints. Existing wearable assistive walking devices can be divided into two categories: active assisting devices and passive assisting devices. Passive assisting devices are mainly composed of various elastic components, which are light in weight, but can only adapt to fixed several gaits. , and the boosting effect is not as obvious as that of the active type, and the introduction of the driver in the active type boosting device leads to an increase in the weight of the overall structure and increases the burd...
