Problems solved by technology

[0003] When many flexible knee joints of exoskeleton robots in the prior art are bent, the angle of the driving force changes continuously due to the change of the joint angle, which leads to the change of the joint torque of the exoskeleton, resulting in energy loss

Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the accompanying drawings in the embodiments of the application. Apparently, the described embodiments are only part of the embodiments of the application, not all of them. Based on the implementation manners in this application, all other implementation manners obtained by persons of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

[0033] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purpos...

Abstract

The application provides a knee joint mechanism for a wearable external skeleton. The knee joint mechanism for the wearable external skeleton comprises at least two connection units connected in series in the up-down direction, wherein each connection unit comprises a connection piece and a steel rope pulley installed on the connection piece, each connection piece comprises two first connection sheets oppositely arranged and a second connection sheet clamped between the two first connection sheets, each first connection sheet comprises a first protruded part protruded upwards relatively to thecorresponding second connection sheet, each second connection sheet comprises a second protruded part protruded downwards relatively to the two corresponding first connection sheets, an installing gap is formed between the first protruded parts of the two first connection sheets oppositely arranged on each connection unit, a poisoning pin hole is formed in each first protruded part, an arc slidechute is formed in each second protruded part, an upper tooth part is arranged on the upper edge of each second connection sheet, and a lower tooth part is arranged on the lower edge of each second connection sheet.

Description

technical field [0001] The present application relates to a knee joint mechanism for a wearable exoskeleton, in particular to a high torque output adaptive knee joint mechanism for a wearable exoskeleton. Background technique [0002] Exoskeleton originally refers to a hard external structure that protects the soft internal organs of organisms in biology, but now exoskeleton robot refers to a type of mechanical device that imitates the state of human motion and enhances human motion ability, integrating bionics and ergonomics , worn on the outside of the human limbs, can improve people's ability in specific aspects such as walking durability and load-bearing capacity. Since the exoskeleton robot involves ergonomics, it requires strong adaptability, not only to be suitable for wearers of different sizes, but also to protect the human joints from danger to prevent human injury during the wearing process. [0003] When many flexible knee joints of exoskeleton robots in the pri...
