An upper limb rehabilitation exoskeleton based on spatial gravity balance

Abstract

The invention relates to the technical field of upper limb rehabilitation, and discloses an upper limb rehabilitation exoskeleton based on space gravity balance, which includes a flexible bag, the inside of which is movably connected with a ratchet, and the surface of the ratchet is movably connected with pawls, the pawls are away from One end of the ratchet is movably connected with a chuck, the surface of the chuck is sleeved with a scroll spring, the surface of the ratchet is movably connected with an elastic belt, both ends of the elastic belt are movably connected with a rotating shaft, and the bottom of the rotating shaft is fixedly connected with a telescopic rod , when the patient wants to bend the arm, the bending of the elbow will stretch the flexible capsule, so the screw is given a certain speed by the meshing shaft and drives the shaft to rotate counterclockwise, so the elastic band on its surface is released, and the tension on the elastic band becomes Therefore, its elastic force shrinks and pulls the elbows on both sides of the flexible capsule to approach each other, thereby achieving the effect of overcoming the potential energy of gravity and allowing it to be adjusted to help patients perform training.

Description

technical field [0001] The invention relates to the technical field of upper limb rehabilitation, in particular to an upper limb rehabilitation exoskeleton based on space gravity balance. Background technique [0002] With the development of modern technology, some bionic exoskeletons have been developed to help patients recover. They are equipped with modern technology products, such as Internet of Things, sensors, information transmission and other technologies, so that they can assist patients in training and prevent patients from being injured by two It is used in the medical field and has good feedback. [0003] However, the disadvantage of this kind of exoskeleton is that due to its many metal parts, its own weight is relatively large. When patients wear it for rehabilitation training, they need to spend extra energy to resist the gravitational potential energy generated by the metal parts, and this gravitational potential energy It cannot be adjusted, so the training...

Problems solved by technology

[0003] However, the disadvantage of this kind of exoskeleton is that due to its many metal parts, its own weight is relatively large. When patients wear it for rehabilitation training, they need to spend extra energy to resist the gravitational potential energy generated by the metal parts, and this gravitational potential energy It cannot be adjusted, so the training effect of the patient is not very good. In addition, when the patient uses this part to train, the muscles cannot be rested during the reciprocating motion stroke, and they are always in a working state, which will cause muscle fatigue. The upper limb rehabilitation exoskeleton with space gravity balance came into being
