A walking aid and auxiliary support mechanism

Abstract

A power-assisted walking and auxiliary support mechanism, which includes a left leg, a right leg, a foot, a waist wearing module and an auxiliary support telescopic rod, the left leg and the right leg are respectively equipped with feet; the left leg and the right leg respectively include hip joints Connector, thigh support rod, thigh rope drive mechanism, knee joint connector, calf support rod, calf rope drive mechanism, ankle joint connector and shock absorption module, hip joint connector is connected with waist wearable module; thigh support rod and hip The joint joints are connected and the two can rotate relatively; the thigh support bar is rotationally connected with the calf support bar through the knee joint joint, and the foot includes soles, electric folding wheels and foot straps; The shock-absorbing module includes a shock-absorbing mechanism and a foot cushion, the foot cushion is installed on the sole of the foot, the shock-absorbing mechanism is connected with the ankle joint connector, and the shock-absorbing mechanism is respectively connected with the foot cushion and the sole of the foot. The invention has good transmission efficiency, is safe and reliable, and improves the smoothness of assisting walking.

Description

technical field [0001] The invention relates to a wearable power-assisted walking device, in particular to a power-assisted walking and auxiliary support mechanism for a robot. Background technique [0002] With the advancement and development of science and technology, people increasingly hope to have a device with functions of assisting walking and assisting standing, so as to reduce the burden on the legs in long-term walking, weight-bearing walking, etc. A wearable power-assisted walking robot is a power-assisted device that can effectively help people reduce the burden on the lower limbs. The device can be worn on the outside of human limbs, and can improve people's ability in specific aspects such as walking durability and weight-bearing capacity. In the future, wearable power-assisted walking robots will be widely used in medical, civil and other fields, greatly improving people's lives. [0003] In recent years, with the development of various driving methods and t...

Problems solved by technology

Among them, the hydraulic drive has the disadvantages of heavy weight and high energy consumption.

However, the pneumatic artificial muscle drive has the disadvantages that it is difficult to control accurately, and it is easy to cause partial damage or even explosion of the pneumatic muscle under high working pressure.

In addition, the existing walking robots with lower limbs lack shock-absorbing devices at joints such as ankle joints and knee joints, and have no auxiliary support function, which cannot alleviate the impact brought by the road surface when walking, which reduces the service life of the exoskeleton and reduces the walking time. The smoothness, reliability and safety of the time, but also accelerate the wear and tear on the human joints
