Exoskeleton lower limb assistance mechanical device for old people

Abstract

The invention relates to physical rehabilitation equipment, in particular to an exoskeleton lower limb assistance mechanical device for old people. The aim of the invention is to provide the exoskeleton lower limb assistance mechanical device for old people, which is convenient to operate, simple in structure and low in cost. The exoskeleton lower limb assistance mechanical device for old people comprises a transmission mechanism, an energy storage mechanism and a locking mechanism, wherein the transmission mechanism comprises a pedal; an ankle joint ball is installed on the pedal; a steady rod is movably connected to the upper portion of the ankle joint ball; a stop sliding block is movably installed on the steady rod; positioning holes are machined in the side face of the stop sliding block; a plurality of pin holes are machined in the steady rod in the movement direction of the stop sliding block; the pin holes correspond to the positioning holes in position; a driving pull rod is movably installed on the upper portion of the steady rod; the energy storage mechanism is installed between the driving pull rod and the stop sliding block; the locking mechanism is installed on one side of the stop sliding block and comprises a stop pin which can be close to or away from the stop sliding block; and the stop pin is used for penetrating through the positioning holes and the pin holes to lock the position of the stop sliding block.

Description

technical field [0001] The invention relates to the technical field of rehabilitation equipment, in particular to an auxiliary mechanical device for assisting the lower limbs of an exoskeleton for the elderly. Background technique [0002] Now the aging population is serious, most of the elderly have the ability to take care of themselves but lack mobility, and the vast majority of the elderly have inflexible legs and feet, most of which are caused by diseases that fell when they were young. The weakness of the elderly lies in the insufficient support of the ankle and hip joints, and the ankle joint lies in the stability of standing. [0003] Aiming at the above-mentioned inconveniences of the elderly, wearable auxiliary equipment is generally used to improve it. The function of the auxiliary equipment is to enable the elderly to stand up easily and safely, and no longer rely too much on the waist support to stand up, so as to avoid the elderly who may fall during the standi...

AI Technical Summary

Problems solved by technology

[0004] The existing auxiliary mechanical devices for lower limbs have complex structures and cumbersome wearing process, which is not conducive to wearing by the elderly

In addition, the existing auxiliary mechanical devices for lower limbs lack necessary protection measures. The auxiliary mechanical devices for lower limbs themselves can move with the movement of the lower limbs. Auxiliary mechanical devices are also difficult to play a protective or auxiliary role
