Wearable upper limb rehabilitation auxiliary training robot

Abstract

The invention discloses a wearable upper limb rehabilitation auxiliary training robot. The robot comprises an elbow joint speed reducer box, a rotator located at the shoulder joint of the robot, an elbow joint crank rocker mechanism and a wearing part, the rotator is fixedly connected with a shoulder side frame of the wearing part through one end of a rotator lower circular truncated cone piece installed on the rotator, the wearing part is fixedly connected with the elbow joint crank rocker mechanism, the elbow joint crank rocker mechanism is rotationally connected with a large gear long shaft of the elbow joint speed reducer box, a stepping motor is fixedly arranged in the elbow joint speed reducer box, and the rotator rotates in two directions. Reciprocating swinging motion of the small arm relative to the large arm is achieved through the elbow joint crank rocker mechanism, and high-speed turnover motion is converted into low-speed reciprocating swinging motion suitable for the rhythm of the human body through the elbow joint speed reducer box and the crank rocker. The shoulder joint rotator also realizes bidirectional free relative rotation of the shoulder and the big arm through the movement of the moving pair.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a wearable auxiliary training robot for upper limb rehabilitation. Background technique [0002] Stroke, also known as apoplexy in life, is a disease in which blood circulation is destroyed due to acute cerebrovascular disease, resulting in local or even whole brain neurological dysfunction. Stroke, as a disease with a high incidence in my country, is a major chronic disease that endangers the health of most residents in China. With the continuous development of my country's economy, people's requirements and expectations for living standards continue to increase, and it is imminent to provide effective and timely rehabilitation exercise therapy for stroke patients. Timely and reasonable upper limb rehabilitation training can improve most of the body functions of patients and even restore them to the original state, thereby improving the quality of life of most patients and reduc...

Problems solved by technology

At present, most of the traditional medical rehabilitation training is based on the manual operation of professional rehabilitation therapists. This method is a time-consuming, laborious, tedious and complicated work for the patients themselves, their families and even the medical staff.

At the same time, due to the large population in our country, the number of patients is immeasurable, and the number of professional rehabilitation therapists is seriously lacking (therapists account for no more than 1%). The recovery effect cannot reach the ideal state of recovery
