Portable wearable power-assisted glove

Abstract

The invention provides a portable wearable power-assisted glove. The portable wearable power-assisted glove comprises a glove body, a bent sensor, a lead screw motor driving device, a steel wire transmission mechanism and a control mechanism. The motion intention of fingers of the human body is obtained by using the bent sensor, the forward rotation and the reverse rotation of a lead screw motor are controlled by the controller, and the bent sensor is tightly connected with a finger stall through a silica sol solution, so that the reading of the sensor is high in stability. According to the portable wearable power assist glove, a rope drive mode is adopted, a steel wire rope simulates a tendon transmission mode so as to drive the fingers to move, so that the glove has an obvious power-assisted effect, the motion form of the glove can be well unified with the hand motion of the human body, and the glove has wearable comfort. Moreover, the rope drive mode has drive flexibility and man-machine interaction safety. A minitype lead screw motor drive mode is adopted in the driving device, and the driving device has the advantages of being small in size, large in driving force, low in mass, high in integration level, simple in control and the like.

Description

technical field [0001] The invention belongs to the field of medical rehabilitation and health products, and in particular relates to a portable wearing power-assisted glove. Background technique [0002] Due to the growth of age, the elderly's finger muscle function continues to decline, or the phenomenon of finger fatigue caused by various diseases is very common. It is often difficult for them to clench their fists, and they seem powerless when they lift things up the stairs or hold the handrails on a bumpy bus. In some fine operations, such as holding a water glass, it is sometimes difficult to restrain the shaking of hands, which seriously affects the daily life of the elderly. In some workplaces, such as production workshops, workers need to carry parts or tools for long hours of labor, which puts a lot of physical pressure on workshop workers. It is of great practical significance to design a portable power-assisted glove for people with degraded finger grasping fun...

AI Technical Summary

Problems solved by technology

Most of the existing power-assisted exoskeletons are driven by mechanical structures, the structure is complex, the wearing process is cumbersome, and its movement form cannot be well unified with the movement form of the human hand, which is uncomfortable to wear. At the same time, the motor is directly connected to the mechanical structure. Drive, high rigidity, unsafe for human-computer interaction

Some existing power-assisted gloves have the flexibility of driving, but they are directly driven by micro-motors, and there is a problem of small driving force. Generally, they can only be used in rehabilitation training, and the power-assisted effect is not obvious.
