Portable wearable power-assisted glove

Abstract

The portable wearing power-assisted glove of the present invention comprises: a glove body, a bending sensor, a lead screw motor driving device, a steel wire transmission mechanism and a control mechanism. The bending sensor is used to judge the movement intention of the human finger, and the forward and reverse rotation of the lead screw motor is controlled by the controller. The bending sensor is closely connected with the finger cot through the silicone solution, so that the sensor reading has high stability. The invention adopts the rope driving mode, and the steel wire rope simulates the tendon transmission form to drive the fingers to move, so that the glove has an obvious power-assisted effect. The compliance of the drive has the safety of human-computer interaction. The driving device of the present invention adopts the driving form of a miniature lead screw motor, and has the advantages of small size, large driving force, light weight, high integration, simple 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.
