Abstract

The invention discloses stepless variable rigid elastic energy storage elements for exoskeleton. Each stepless variable rigid elastic energy storage element comprises a hollow support shell, a hollowrotating shaft disposed in the support shell, a compression stopping block disposed in the support shell, a Kevlar line, a cylindrical spiral compression spring and an adjusting hand wheel, wherein the bottom end of the Kevlar line is connected with the compression stopping block, and the upper end of the Kevlar line penetrates the middle of the rotating shaft and extends upwardly out of the support shell. The bottom end of the cylindrical spiral compression spring is fixedly connected with the compression stopping block, and the upper end of the cylindrical spiral compression spring is arranged on the rotating shaft in a sleeving mode. The adjusting hand wheel is arranged at the upper end of the rotating shaft and used for adjusting the amount of compression of the cylindrical spiral compression spring. By rationally arranging the stepless variable rigid elastic energy storage elements for the exoskeleton on each joint moving part of an exoskeleton device, the energy of the joints ofthe exoskeleton device is cyclically stored and released in a gait cycle by the energy storage elements, patients are helped to walk, and specific active training actions are completed.

Description

technical field [0001] The invention relates to the field of medical rehabilitation equipment, in particular to a steplessly variable stiffness elastic energy storage element for an exoskeleton. Background technique [0002] The exoskeleton device can effectively support part of the patient's body weight, realize active assisted walking, improve the coordination of lower limb muscles, increase the range of motion of the lower limb joints, thereby improving the movement function of the patient's lower limbs; the energy storage element is to realize its The key technology of the function is to store and release the energy of each joint of the exoskeleton equipment in a gait cycle through the energy storage element, to help the patient walk with assistance, and to complete specific active training actions. Among the existing energy storage components, the electric energy storage generates a large amount of heat, and the wiring is complicated. The external power supply increases...
