Abstract

A wearable DOF (dual degrees of freedom) elbow rehabilitation training device relates to elbow rehabilitation training devices and in particular relates to the wearable DOF elbow rehabilitation training device. The wearable DOF elbow rehabilitation training device is used for solving the problem that the existing elbow rehabilitation devices inconveniently improve elbow joint drive and are complicated in structure, relatively low in accuracy and efficiency and poor in adaptability. The wearable DOF elbow rehabilitation training device comprises a forearm, an upper arm, a link assembly, a first motor, a second motor and a connecting plate, wherein the first motor is mounted at one end of the forearm, one end of the connecting plate is connected with a rotating shaft of the first motor, the other end of the connecting plate is connected with one end of the upper arm through the link assembly, and a rotating shaft of the second motor is connected with the link assembly. The invention belongs to the field of medical apparatus and instruments.

Description

technical field [0001] The invention relates to an elbow rehabilitation training device, in particular to a wearable two-degree-of-freedom elbow rehabilitation training device, which belongs to the field of medical devices. Background technique [0002] Exoskeleton robot is a kind of complex man-machine combination technology, which integrates the knowledge of many scientific fields such as machinery, sensing, control, information, electronic technology and artificial intelligence, and combines human intelligence with the mechanical energy of mechanical power devices. , through human-machine physical contact to transmit force and motion to realize functions such as motion assistance and posture detection, and rely on sensors to realize information interaction with the wearer. [0003] After more than 40 years of development, exoskeletons have become more and more common in many fields. For example, in the military, the assistance of exoskeletons will enhance the endurance o...
