Back connecting device for lower limb rehabilitation robot

Abstract

The invention provides a back connecting device for a lower limb rehabilitation robot. The back connecting device comprises a bottom layer structure connected with the lower limb rehabilitation robot,a middle structure arranged in the bottom layer structure and capable of moving up and down, a connecting structure installed on the middle structure, an upper backrest structure and a lower backreststructure, wherein the upper backrest structure and the lower backrest structure are arranged on the side, away from the bottom layer structure, of the connecting structure, and the extending lengthof the upper backrest structure and the extending length of the lower backrest structure are adjustable. A lead screw is vertically arranged in the middle of the bottom layer structure, a worm and gear pair is arranged on the top of the lead screw, a first worm gear is coaxial with the lead screw, a worm is perpendicular to the lead screw, first hand wheels are arranged at the two ends of the worm, the lead screw is provided with a moving block matched with the lead screw in a sleeving manner, and the middle structure is fixedly connected with the moving block. The problems that a left leg fixing mechanism and a right leg fixing mechanism of the lower limb rehabilitation robot are not flexible in up-down and left-right adjustment, and the supporting positions of the backrest structures areinconvenient to adjust are solved.

Description

technical field [0001] The invention relates to the technical field of rehabilitation robot equipment, in particular to a back connection device for a lower limb rehabilitation robot. Background technique [0002] According to statistics, only 3% to 10% of patients suffering from disabling neurological diseases such as stroke, spinal cord injury, trauma, and Green-Barre can recover to walk 50m independently within 3 years. For many patients who are temporarily unable to walk due to various reasons, restoring walking is their first wish, and it is also an important part of rehabilitation medicine research. Weight-reducing walking training is a new rehabilitation treatment technique aimed at lower limb dysfunction and improving walking ability. It started in the 1980s in foreign countries, and has been widely used and developed in China in the past ten years. It is also one of the hot spots of rehabilitation medicine research in recent years. [0003] The exoskeleton-type l...
