Power-assisted walking and auxiliary supporting mechanism

Abstract

The invention discloses a power-assisted walking and auxiliary supporting mechanism. The power-assisted walking and auxiliary supporting mechanism comprises a left leg, a right leg, feet, a waist wearing module and an auxiliary supporting telescopic rod, wherein the feet are installed on the left leg and the right leg correspondingly, the left leg and the right leg each comprise a hip joint connecting piece, a thigh supporting rod, a thigh rope driving mechanism, a knee joint connecting piece, a shank supporting rod, a shank rope driving mechanism, an ankle joint connecting piece and a vibration reducing module, the hip joint connecting pieces are connected with the waist wearing module, the thigh supporting rods and the hip joint connecting pieces are connected and can rotate relatively,the thigh supporting rods are rotationally connected with the shank supporting rods through the knee joint connecting pieces, the feet comprise foot bottom, electric folding wheel sets and foot binding belts, the vibration reducing module comprises vibration reducing mechanisms and foot buffer pads, the foot buffer pads are installed on the foot bottom, the vibration reducing mechanisms are connected with the ankle joint connecting pieces, and the vibration reducing mechanisms are connected with the foot buffer pads and the foot bottom. The power-assisted walking and auxiliary supporting mechanism is good in transmission efficiency, safe and reliable, and the smoothness during power-assisted walking is improved.

Description

technical field [0001] The invention relates to a wearable power-assisted walking device, in particular to a power-assisted walking and auxiliary supporting mechanism for a robot. Background technique [0002] Along with the progress and development of science and technology, people more and more hope to have a kind of device that has the function of assisting walking and assisting standing, to reduce the burden of both legs under the situation such as walking for a long time, carrying weight. A wearable power-assisted walking robot is a kind of power-assisted device that can effectively help people reduce the burden on the lower limbs. The device can be worn on the outside of the 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 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
