Abstract

The invention discloses an elbow freedom degree achieving device for wearable rehabilitation training device and a working principle thereof. A motor is connected with a left rotating and right rotating integrated lead screw and fixed to a motor fixing base. The upper arm and the forearm of the arm are sleeved with an upper arm support and a front arm support respectively, a synchronous belt fixing device is arranged on the lower side of a left rotating nut, a synchronous belt adjusting device is arranged on the upper side of a right rotating nut, and the synchronous belt fixing device and the synchronous belt fixing device are connected through a synchronous belt wound around a synchronous pulley. The driving motor and the transmission mechanism are arranged on the outer side of an upper arm body in the axis direction of the upper arm, the interference with the outside environment is reduced in the movement process, the left and right rotating integrated rolling ball lead screw and a sliding block mechanism serve as a transmission system, good self-locking performance is achieved, the controllability is good, both the left rotating nut and the right rotating nut have a certain stroke, and it is ensured that the integral mechanism has the limit function. More existing standard components are utilized in the whole mechanism, and compared with the scheme that the same function is achieved by utilizing a speed reducer, the economic cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical mechanical appliances, in particular to a device for realizing the degree of freedom of the elbow of a wearable rehabilitation trainer and its working principle. Background technique [0002] The upper limb rehabilitation training orthosis is a medical device that assists patients with inflexible movements of the upper limbs to perform rehabilitation training. The upper limbs of the human body include multiple degrees of freedom of the elbow and shoulder, and the degree of freedom of the elbow is to realize the flexion and relaxation of the forearm relative to the upper arm. It is an important movement hub for picking, moving, and lifting objects in daily life and work. The defect of the degree of freedom of the elbow will bring great inconvenience to the life of the patient. Most of the existing upper limb rehabilitation training devices are non-wearable upper limb rehabilitation training device...
