Upper limb rehabilitation training device based on grouping coupling drive

Abstract

The invention discloses an upper limb rehabilitation training device based on grouping coupling drive. The upper limb rehabilitation training device based on the grouping coupling drive comprises a shoulder three-degree-of-freedom self-adapting mechanism, a first coupling movement mechanism, a shoulder connecting component, a second coupling movement mechanism and a wrist two-degree-of-freedom self-adapting mechanism, the first coupling movement mechanism is firmly connected with the shoulder three-degree-of-freedom self-adapting mechanism, the shoulder connecting component is rotationally connected with the first coupling movement mechanism, the second coupling movement mechanism is firmly connected with the shoulder connecting component, and the wrist two-degree-of-freedom self-adapting mechanism is firmly connected with the second coupling movement mechanism. The upper limb rehabilitation training device based on the grouping coupling drive is capable of regulating automatically according to the affected limb sizes of different patients and the concrete use situations, the human body can coordinate with the mechanism, the human body comfort and safety coefficient are greatly improved, and the movements transit smoothly and coordinate with each other so that the upper limb rehabilitation training device based on the grouping coupling drive is capable of finishing various complex active and passive training actions.

Description

technical field [0001] The invention belongs to the field of rehabilitation medical equipment, and more specifically relates to an upper limb rehabilitation training device based on group coupling drive. Background technique [0002] Today, with the rapid development of science and technology and the general improvement of people's living standards, some groups still suffer physically and mentally due to problems such as limb motor dysfunction. There are many reasons for human limb movement dysfunction, such as industrial production accidents, traffic accidents and other accidents, stroke, hemiplegia and other diseases, as well as the inconvenience and slowness of movement caused by human aging. Most of these limb movement dysfunction patients cannot take care of themselves , has caused a heavy blow to the physical and mental health of patients, and has also caused a great impact and burden on social development. In this context, the development and production of rehabilita...

Problems solved by technology

[0006] If it involves the movement of the shoulder joint, elbow joint and wrist joint, including five active degrees of freedom and five adaptive passive degrees of freedom, the active degrees of freedom need to provide power drive, most of the robotic arms today use a free The degree corresponds to a driving control mode, which not only increases the complexity of the control, but also makes the overall mechanism relatively cumbersome, requires more raw materials, and the cost is also higher
