An adaptive ankle exoskeleton

Abstract

The present invention relates to the technical field of robot exoskeleton, and discloses an adaptive ankle joint exoskeleton, which includes a housing box; the housing box is provided with an underfoot pressure mechanism and an underfoot transmission mechanism connected to each other, and the outside of the housing box is provided with a The reset linkage mechanism matched with the underfoot transmission mechanism, the reset linkage mechanism is connected with a calf sheath belt; the wearer wears and connects to the exoskeleton through the calf sheath belt; the underfoot pressure mechanism is used to bear the wearer's the underfoot pressure and transmit it to the underfoot transmission mechanism; the underfoot transmission mechanism moves under the action of the underfoot pressure and drives the reset linkage mechanism to work; the reset linkage mechanism is used to store energy, And when the pressure under the foot is released, the energy is released to assist walking. The invention can reduce the energy consumption of walking, and has the advantages of simple structure, light weight, reliable function and the like.

Description

technical field [0001] The present invention relates to the technical field of robot exoskeleton, and more specifically relates to an adaptive ankle exoskeleton. Background technique [0002] my country has entered an aging society. As of 2017, my country's elderly population over the age of 60 exceeded 240 million. Due to the decline of their own muscle strength, the elderly have varying degrees of decline in walking ability. Medical assistive devices help the elderly to live independently and complete basic tasks of daily life during the decline stage of muscle strength. As a portable and efficient medical auxiliary device, the unpowered ankle exoskeleton does not require external energy input, and can assist the elderly in walking only by relying on the body's own gravity and limb movement to do work. Compared with the driven lower extremity exoskeleton, which relies on complex and heavy energy, drive, sensing and control systems to adapt to the changing gait of the hum...

However, due to its own structural design, it has a great impact on the normal movement of the ankle joint

[0006] Patent CN207722054U proposes a new type of exoskeleton ankle joint device, which has a simple structure and the effect of cushioning and shock absorption, but due to the design considering the cushioning effect and the use of too much rigid structure, the free movement of the ankle joint will be limited.
