Dynamically adjustable flexible arch-ankle system and control method thereof

Abstract

The invention discloses a dynamically adjustable flexible arch-ankle system and a control method thereof. The left foot flexible arch-ankle module and the right foot flexible arch-ankle module are connected with the air pressure source and the sensing control module; the left foot flexible arch-ankle module and the right foot flexible arch-ankle module are the same in structure, shoes in the flexible arch-ankle modules are electrically connected with the sensing control module, flexible drivers are installed in the shoes and connected with an air pressure source through air pipes and electromagnetic switch valves, and the electromagnetic switch valves are electrically connected with the sensing control module; the shoe is worn on the foot of a wearer, according to the gait of the wearer, the sensing control module controls the opening and closing of the electromagnetic switch valve to control the on-off of the air path where the corresponding flexible driver is located, and then the state of each flexible driver is controlled, so that the supporting force of each flexible driver on the arch and ankle joint of the wearer is dynamically adjusted. The system can be tightly attached to the arch and the ankle of a wearer, supporting is carried out only when needed, and the normal assisting effect can be achieved.

Description

technical field [0001] The invention relates to a foot arch-foot-ankle system, in particular to a dynamically adjusted flexible foot-arch-foot-ankle system and a control method thereof. Background technique [0002] The human foot is a very complex system that contains numerous bones, joints, muscles, ligaments, nerves and blood vessels. Among them, the arch of the foot and the ankle joint play a very important role in bearing the weight of the human body, absorbing the ground impact, distributing the pressure on the sole of the foot and maintaining balance, while the normal gait of the human body bears overload for a long time, such as standing or walking for a long time, the foot The arch may drop, causing injury or pain in the foot, followed by foot disorders such as gait disorders or even flat feet. [0003] In order to prevent the arch of the foot from being too low and reduce the damage caused by the drop of the foot arch, the orthopedic insole has been continuously d...

Problems solved by technology

[0005] In order to overcome the problems of existing foot orthotics, the present invention provides a dynamically adjustable flexible arch-ankle system and its control method, which can The bottom pressure sensor acquires the current gait of the wearer, and dynamically supports and assists the arch of the foot and the ankle joint according to different gait events of the human body; at the same time, the pneumatic flexible driver is used to realize flexible active assist and relieve the driver from affecting the human foot.
