Flexible driver

Abstract

The invention discloses a flexible driver. A bending driving unit and an extension driving unit are alternatively connected to form a combined driving unit, a flexible seal cover is connected to one end of the combined driving unit, and a tubular structure with one closed end and one opened end is formed; the opening end of the tubular structure communicates with an air inlet guide pipe, a partition board is arranged in the tubular structure, an inner cavity of the tubular structure is divided into an upper cavity and a lower cavity, flexible valves are arranged on openings of the upper cavityand the lower cavity, an opening is formed in the partition board on the flexible seal cover area, a flexible valve is arranged on the opening, a torsion driving unit is connected between the open end of the tubular structure and the air inlet guide pipe, under extension, bending and torsion of the driver, fingers or limb joints are driven to move within the proper angle range, long-term rigidityof the hand is avoided, hand functional rehabilitation actions of hand bending, extension, inward buckling, outward extending, limb extension and the like can be finished, physical ergonomics are met, flexible degree is high, and the comfort is good.

Description

Technical field [0001] The invention relates to the technical field of training and rehabilitation equipment, and more specifically to a flexible drive. Background technique [0002] With the improvement of my country's medical standards, the average life expectancy of our population has increased year by year. Data shows that the average life expectancy of our country is 75 years old. According to the United Nations standard for aging society, our country has already entered an aging society. At the same time, the aging population is a high incidence of stroke, the incidence rate is as high as 12.3%, and most of the patients with hemiplegia caused by stroke are those with hand dysfunction. Scientific research has found that people have to perform approximately 1,500 grasping movements every day. Hands are the most frequently used body parts in daily life. The healthy and flexible hands are an important guarantee for people's quality of life. [0003] At present, patients with han...

Problems solved by technology

At present, on the one hand, the soft finger part of the existing pneumatic software rehabilitation gloves has the problem of low bending range. For example, the patent CN 102920568 A discloses a McKibben type pneumatic artificial muscle, which can be stretched by inflation and deflation; on the other hand, such as Patent CN 109431744 A discloses a portable software rehabilitation finger device and its control method, its driver adopts PneuNet cavity structure to realize the bending and stretching of the whole finger

The above scheme can achieve the relaxation of long-term stiff hand muscles, but neglects to give sports patients hand joints appropriate angle rehabilitation training

At the same time, the soft actuators connected in parallel with the existing pneumatic rehabilitation gloves usually require independent gas pipeline control, and the function conversion of the soft fingers is realized through the external electromagnetic reversing valve, but the common structure is relatively complicated, the volume is large, the portability is poor, and the cost is high. and other shortcomings
