Embodiment Construction

[0058] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0059] see figure 1 , Figure 1A , Figure 1B As shown, a three-degree-of-freedom hip exoskeleton designed in the present invention for assisting applications is aimed at the flexion and extension of the human hip joint, and is actively driven by a motor to assist the human body to walk. It includes a hip joint backrest assembly 1 , a right thigh assembly 2 , a right assist wearing assembly 3 , a left thigh assembly 4 and a left assist wearing assembly 5 .

[0060] In the present invention, the right thigh and the left thigh are driven by only one DC motor (2E, 4E) respectively to realize the mechanism design of double rotating pair plus moving pair. Therefore, you can consider choosing a motor with a lighter weight (such as the HT-02 motor produced by Shanghai Haitai Electromechanical Company) when selecting the motor type. The DC motor has a rated torqu...

Abstract

The invention discloses a three-degree-of-freedom hip joint exoskeleton for power-assisted application, which aims at the flexion and extension movement of a hip joint of a human body and adopts a motor active driving mode to assist the human body to walk. The three-degree-of-freedom hip joint exoskeleton comprises a hip joint back backup plate assembly (1), a right thigh assembly (2), a right assisting wearable assembly (3), a left thigh assembly (4) and a left assisting wearable assembly (5). Aiming at the abduction and adduction movement of the hip joint of the human body, a mechanism with double revolute pairs and a sliding pair is designed; a wearing mechanism capable of rotating around the thigh is designed aiming at the internal and external rotation motion of the hip joint; and a back mechanism is symmetrically adjusted on the two sides through meshing of a gear and a rack. Therefore, the adaptation of three degrees of freedom of motion of the hip joint of the rehabilitative patient is realized.

Description

technical field [0001] The invention relates to a rehabilitation mechanism, more specifically, a three-degree-of-freedom hip exoskeleton for assisting applications, which is aimed at the flexion and extension of the human hip joint and is actively driven by a motor to assist the human body to walk. Background technique [0002] At present, population aging is a common problem in the world. China's elderly population will exceed 300 million, and China will enter a moderately aging society. The elderly may suffer from lower limb dysfunction due to stroke and other reasons. Traditional rehabilitation training methods mainly rely on rehabilitation physiotherapists to conduct one-on-one rehabilitation training, which is labor-intensive and time-consuming and cannot meet the rehabilitation training needs of a large number of patients. In this case, the exoskeleton rehabilitation machine can well solve the problem of highly repetitive rehabilitation training, and the precise contro...
