Problems solved by technology

However, the existing rigid wearable devices have the following disadvantages in terms of cooperating with the human body and improving the efficiency of movement: (1) There is interference between the device and the biological joint due to misalignment between the device joints and the human body joints during motion ; (2) The degree of freedom of movement of biological joints is restricted due to the degree of freedom of the device being less than that of the joints of the lower limbs of the human body; (3) Due to the large weight and inertia that are not fully controlled and compensated by the device itself, the user is in the When wearing the device, it needs to pay extra energy consumption to drive some devices
That is, these devices provide assisting forces to the user's limb joints on one side, and apply tangential forces tangential to the user's skin surface on the other side, and these tangential forces cause the user's skin surface to be rubbed , squeezing, and thus causing user discomfort
Moreover, these devices will not be able to provide sufficient assisting force when the user's skin is loose and the muscles are not rigid enough to provide a sufficient tangential force as a reaction to the assisting force

Abstract

The invention relates to an ankle-assisted exoskeleton device. The ankle-assisted exoskeleton device can be easily worn, does not restrain joints of a user, and does not depend on the skin surface of the user to provide tangential force while providing lower limb assistance, so that the daily action ability and the action efficiency of the user can be improved.

Description

technical field [0001] The present invention relates to the technical field of wearable devices, in particular to an ankle assisting exoskeleton device that provides auxiliary force for a user's ankle and can be used daily. Background technique [0002] At present, wearable devices for lower limbs are designed for different purposes, including wearable devices that enhance human strength, provide rehabilitation training, improve mobility efficiency and reduce human energy consumption. For human strength and rehabilitation purposes, wearable lower-limb devices or exoskeletons typically rely on full-leg rigid metal structures to provide external body support. These lower extremity exoskeleton systems could enable the able-bodied or physically handicapped to perform tasks that they would not be able to do using their own strength. However, the existing rigid wearable devices have the following disadvantages in terms of cooperating with the human body and improving the efficien...
