Abstract

The invention provides a hand exoskeleton device with flexibility and a sectional drive function. The device comprises a forearm platform, a palm platform and multiple finger assemblies; the finger assemblies at least comprise a thumb assembly, an index finger assembly and a middle finger assembly, the palm platform is located among the forearm platform and the finger assemblies, is used for connecting the thumb assembly, the index finger assembly and the middle finger assembly and contains a rotating drive system used for making fingers perform abduction and adduction, and the forearm platform is used for being connected to the finger assemblies and contains a linear drive system used for making the fingers carry out extension and buckling; and the linear drive system comprises an antergic linear drive device and a linear elastic tendon device in pair. The hand exoskeleton device has flexibility, and the degree of freedom consistent with finger joints of the human is obtained, so thatthe hand exercise is more flexible and comfortable.

Description

technical field [0001] The invention relates to the field of human body motion auxiliary equipment, in particular to a hand exoskeleton device with flexibility and segmented driving functions. Background technique [0002] Stroke is the second leading cause of disability among people with dementia. Current rehabilitation programs aimed at improving motor function include inpatient rehabilitation and home rehabilitation. Home rehabilitation provides enhanced health training effects, but requires reliable, portable and inexpensive rehabilitation equipment more than usual hospital rehabilitation. [0003] Exoskeleton rehabilitation offers solutions that ideally include portable rehabilitation devices and are pre-programmed within their platforms for rehabilitation needs, eliminating the need to prepare the patient's home or recruit service providers. Therefore, exoskeleton rehabilitation training robots have good practical value in affordable home rehabilitation training. ...
