Lower limb exoskeleton auxiliary load bearing foot device

Abstract

The invention discloses a lower limb exoskeleton auxiliary load bearing foot device comprising a contact plate, a support plate, a human body foot arch mechanism and an elastic damping mechanism. Thecontact plate is used for being in complete contact with the human body foot; the human body foot arch mechanism is arranged between the contact plate and the support plate and is connected with the contact plate and the support plate to be used for simulating the human body arch buffer stress; the elastic damping mechanism is mounted on the lower surface of the support plate and used for increasing elastic damping of the foot device; the human body foot arch mechanism comprises an elastic connecting plate, a longitudinal arch unit and a transverse arch unit; the elastic connecting plate is located at the center position of the upper surface of the support plate; the longitudinal arch unit is longitudinally connected with the elastic connecting plate and the support plate to realize simulation of a longitudinal arch of the foot; and the transverse arch unit is transversely connected with the elastic connecting plate and the support plate to realize simulation of the transverse arch ofthe foot. The problems that the lower limb exoskeleton auxiliary load bearing foot device and the ground are in contact and generate large impact, and the work efficiency is reduced are solved.

Description

technical field [0001] The invention relates to the field of robot exoskeleton, in particular to a foot device for assisting load-bearing lower extremity exoskeleton. Background technique [0002] Since the beginning of the 21st century, scientific research on humanoid robots has become a popular research direction in the field of robotics research. All over the world, different scientific research institutions have developed various types of humanoid robots with different uses, and they play a pivotal role in assisting or replacing human beings in life and production. However, it is accompanied by many problems in actual use. For example, robots are operated and executed by previously set programs, and they cannot predict, and cannot adapt to emergencies like humans, so it is difficult to mass-produce them in large areas and put them into practical use. In order to overcome this problem, some scientists have proposed a wearable robot that can rely on human limbs and joint...

AI Technical Summary

Problems solved by technology

[0003] Existing exoskeletons often work under heavy loads, and when the feet touch the ground, there will be a large impact, and the feet will definitely feel tired, reducing the comfort of the user, unable to maintain speed and endurance, and impacting the spine at the same time and brain, damage to health, and the impact reduces productivity

At present, the foot structure of the exoskeleton at home and abroad is only one plate, which will produce a large impact when it comes into contact with the ground. None of them involve the comfort of the foot joints, and the design of the foot is not perfect.
