Asymmetric cavity channel contact enhanced wearable soft rehabilitation glove

Abstract

The invention provides an asymmetric cavity contact enhanced wearable soft rehabilitation glove which comprises a soft glove body and a soft driver, and the soft driver and the soft glove body are used in cooperation. The soft driver comprises air cavity upper-layer composite cloth, air cavity lower-layer composite cloth and restraint layer composite cloth, the air cavity upper-layer composite cloth and the air cavity lower-layer composite cloth are connected through hot pressing to form an air cavity with air tightness, the air cavity upper-layer composite cloth and the air cavity lower-layercomposite cloth are unequal in width, and an air cavity upper-layer and air cavity lower-layer asymmetric structure is formed. The air cavity is folded to form corrugated wrinkles, and one side of the air cavity is connected to the restraint layer composite cloth. The grabbing force output by the rehabilitation glove is improved through the contact enhancing effect of the asymmetric air cavitiesand the contact pads, the driver is manufactured through the asymmetric cavity channels with the unequal widths up and down, the sectional inertia moment is changed, and the output grabbing force is improved.

Description

technical field [0001] The invention relates to the technical field of soft rehabilitation exoskeleton, in particular to a wearable soft rehabilitation glove with asymmetric cavity contact enhancement. Background technique [0002] Hand motor dysfunction caused by stroke, spinal injury, Parkinson's syndrome, etc. can significantly reduce the patient's daily activities, such as grasping objects, drinking water, etc., thereby reducing the patient's quality of life. The development of rehabilitation robots provides an important tool for rehabilitation training of patients' hand function. [0003] Traditional rigid hand function rehabilitation exoskeletons have disadvantages such as large mass, complex mechanism, and joint dislocation; recently developed soft rehabilitation gloves have improved safety and comfort, but the grip provided by gloves is insufficient, which limits the use of soft rehabilitation gloves in rehabilitation training. and applications in daily life.

Problems solved by technology

[0003] Traditional rigid hand function rehabilitation exoskeletons have disadvantages such as large mass, complex mechanism, and joint dislocation; recently developed soft rehabilitation gloves have improved safety and comfort, but the grip provided by gloves is insufficient, which limits the use of soft rehabilitation gloves in rehabilitation training. and applications in daily life

[0004] After searching, the patent document CN111631904A discloses a semi-wearable palm rehabilitation exoskeleton. The exoskeleton is driven by a hydraulic cylinder, a piston rod, etc. to drive the connecting rod mechanism to drive the fingers to rotate, and can assist the hand in rehabilitation training; but the exoskeleton The quality of the parts is large, the types are many and complex, and the human-machine compatibility of the mechanism is insufficient

[0005] Patent document CN109223430A discloses a wearable software rehabilitation glove and its control method and system, which have better wearing comfort and safety; width, forming a symmetrical cavity; the grip force output by the driver is insufficient, which limits the gripping ability of rehabilitation gloves and the application in rehabilitation training
