Embodiment Construction

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] It should be noted that when an element is referred to as being “connected to” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity o...

Abstract

The invention provides a power-assisted type bionic joint. The power-assisted type bionic joint comprises an upper joint component, a lower joint component and a power-assisted mechanism. The power-assisted mechanism comprises a harmonic speed reducer and a driving motor for driving the harmonic reducer. The upper joint component is rotationally connected with the lower joint component, and the lower joint component comprises a first joint seat and a second joint seat, the first joint seat and the second joint seat are arranged side by side. An accommodation cavity is arranged between the first joint seat and the second joint seat and accommodates the power-assisted mechanism. The power-assisted mechanism with the driving motor and the harmonic speed reducer is placed in the accommodationcavity, so that the power-assisted mechanism driving the rotation of the upper joint component and the lower joint component is placed into the inner bionic joint, the structure of the power-assistedtype bionic joint is compact, the size of the power-assisted type bionic joint is small and the weight of the power-assisted type bionic joint is light. When the power-assisted type bionic joint is inuse, the driving motor drives the harmonic speed reducer to provide enough power, drives the upper joint component to rotate relative to the lower joint component, and reduces the motion inertia of the bionic joint, so that the influence and restriction on the normal flexion and extension motion of the bionic prosthesis or the bionic robot is little.

Description

technical field [0001] The invention belongs to the technical field of bionic joints, and more specifically relates to a power-assisted bionic joint. Background technique [0002] In recent years, with the development of mechatronics technology / robot technology, bionic prosthetics or bionic robots have gradually developed from low-level, simple drive control to high-level, complex intelligent drive control. Due to bionic prosthetics or bionic robots, it is usually necessary to set dynamic bionic joints at the movable joints of the moving limbs to realize the flexion and extension of the limbs, so as to reduce the energy consumption of the bionic prosthetics or bionic robots during the movement. However, the dynamic bionic joints currently used in bionic prosthetics or bionic robots usually adopt the transmission structure of bevel gear transmission, worm gear transmission or rope pulley transmission, which not only requires a large power motor to drive, but also leads to a l...
