A three-degree-of-freedom passive force-interaction upper limb rehabilitation training instrument

Abstract

The invention discloses a three-degree-of-freedom passive force interaction upper limb rehabilitation training instrument. The three-degree-of-freedom passive force interaction upper limb rehabilitation training instrument comprises a mounting bottom plate; a training unit and a motion detection unit are sequentially arranged on a plate body of the mounting bottom plate; the training unit comprises a handle structure and a resistance structure; the handle structure comprises a handle, an upper base, a lower base, a ball rotor, a movable shaft rod, a gyroscope and a movable shaft which are connected in sequence; and the resistance structure comprises a limiting base, a first ox eye wheel, a second ox eye wheel and a friction plate. The training unit and the motion detection unit are sequentially arranged on the plate body of the mounting bottom plate; a user is trained and rehabilitated by operating the training unit; and the motion detection unit is used for detecting the training intensity of the training unit in real time.

Description

technical field [0001] The invention relates to the technical field of rehabilitation, in particular to a three-degree-of-freedom passive force-interaction upper limb rehabilitation training instrument. Background technique [0002] At present, there are mainly two types of structural design schemes for upper limb rehabilitation machines at home and abroad: the end-support type and the exoskeleton type. The end-support type uses an ordinary linkage mechanism or a series robot mechanism as the main mechanism to support the end of the rehabilitation trainer's movement. and traction, so as to realize the rehabilitation of upper limbs. The way of introducing force interaction technology into the upper limb rehabilitation training system and assisting the injured in rehabilitation treatment has been gradually accepted by researchers at home and abroad, and has become one of the preferred methods for upper limb recovery. Traditional The force interaction device mainly uses active ...

Problems solved by technology

[0002] At present, there are mainly two types of structural design schemes for upper limb rehabilitation machines at home and abroad: the end-support type and the exoskeleton type. The end-support type is based on an ordinary linkage mechanism or a series robot mechanism as the main mechanism to support the end of the rehabilitation trainer's movement. and traction, so as to realize the rehabilitation of upper limbs. The way of introducing force interaction technology into the upper limb rehabilitation training system and assisting the injured in rehabilitation treatment has been gradually accepted by researchers at home and abroad, and has become one of the preferred methods for upper limb recovery. Traditional The force interaction device is mainly based on active force feedback, which has problems such as poor safety, long response time, non-adjustable friction, complex structure, and high cost. Therefore, it is urgent for those skilled in the art to solve this problem
