Portable power assisting device for assisting lower limbs of human body to climb stairs

Abstract

The invention discloses a portable power assisting device for assisting lower limbs of a human body to climb stairs. The portable power assisting device comprises a power assisting mechanism, a controller and a direct current power supply. The power assisting mechanism comprises a waist supporting part, two executors, two leg fixing racks and two leg bandages, wherein the waist supporting part is U-shaped for being matched with the waist of the human body; the two executors are separately mounted on two ends of the U shape of the waist supporting part for assisting two lower limbs of the human body to climb stairs; the two leg fixing racks are separately mounted on the two executors; and the two leg bandages are separately mounted on the two leg fixing racks and are separately bonded to the two lower limbs of the human body if being used. The controller controls the two executors to operate and the direct current power supply provides a power supply to the two executors. A power assisting effect can be achieved by assisting flexion and extension of quadriceps femoris without a targeted structural design for integrally considering motions of hip joints, knee joints and ankle joints, so that the cost is lowered to a great extent.

Description

technical field [0001] The invention relates to a booster in the medical field, in particular to a portable booster for assisting the lower limbs of a human body to climb stairs. Background technique [0002] At present, in the field of helping the elderly and the disabled and medical rehabilitation, the general assisting devices for the lower limbs include hip joints, knee joints and ankle joints. The structure is complex, and users need to be trained before using them; poor comfort. The document (Ken YASUHARA.Walking Assist Device with StrideManagement System[J].Honda R&D Technical Review, 2009.10:57-66) provides a small assistive walking device for lower limbs. Since it adopts the structure of a disc motor combined with a planetary gear, The output torque of the device is small, and it is only used for running and walking in place training, without direct assist effect; the speed output lacks closed-loop control, and the output speed cannot be stably controlled. It is d...
