Problems solved by technology

At the same time, it adds a manually operable posture adjustment structure. When the user is in a sitting or squatting position, the user can manually adjust the knob so that the device does not provide auxiliary force.
[0004] However, the existing knee exoskeleton is not sufficiently bionic, and the user may experience discomfort when using it for a long time; in addition, the existing passive knee exoskeleton cannot automatically determine whether to provide auxiliary force according to the posture of the user, and some products It can be manually adjusted by the user, but the manual adjustment method is not convenient enough

Abstract

The application provides a boosted exoskeleton for a knee joint. The boosted exoskeleton comprises a thigh structure, a shank structure, a link structure and a gear structure arranged on the link structure; the thigh structure is movably connected with the shank structure through the link structure; an energy storage assembly is arranged on the thigh structure; the gear structure comprises a driving wheelset rotating along with the link structure, an intermediate wheelset for driving the energy storage assembly to store energy and a locking mechanism for limiting the intermediate wheelset to rotate along a preset direction; the driving wheelset is in transmission connection with the intermediate wheelset; the locking mechanism comprises a lock component, ratchets, a driving wheel, a first ratchet mechanism and a locking wheel; the lock component rotates along with the driving wheelset; the ratchets are arranged at a movable end of the lock component and are used for limiting the locking wheel to rotate along a preset direction; the driving wheel is in engaged connection with the middle wheelset and is in transmission connection with the locking wheel through the first ratchet mechanism; and the first ratchet mechanism is used for driving the locking wheel to reversely rotate along the preset direction. The device provided by the application can achieve automatic locking after knee bending without providing boost.

Description

technical field [0001] The present application relates to the field of walking assistance devices, in particular to a knee joint assisting exoskeleton. Background technique [0002] As of the end of 2019, the number of people suffering from knee arthritis in my country has reached 120 million. Knee exoskeletons can help patients with knee-related diseases to provide a certain amount of assistance when walking, improving the durability of walking and knee joints. carrying capacity, thereby improving the quality of life of such groups of people. [0003] There is an existing non-powered knee exoskeleton, which adopts a double pivot hinge structure in the knee joint, which is similar to the motion mode of the knee joint to a certain extent. At the same time, it has added a manually operable posture adjustment structure. When the user is in a sitting or squatting position, the user can manually adjust the knob, so that the device does not provide auxiliary force. [0004] Howev...
