Joint stiffening device of repeatable flexible space suit based on cylindrical air bag and joint stiffening device of repeatable flexible space suit application thereof

Abstract

The invention discloses a joint stiffening device of repeatable flexible space suit based on a cylindrical air bag and a joint stiffening device of repeatable flexible space suit application thereof. The joint stiffening device of repeatable flexible space suit is made on the basis of a cylindrical air bag and the initial shape of the space suit is a straight cylinder shape. The cylindrical air bag is composed of a base, a cylindrical air bag and a film, wherein a plurality of cylindrical air bags are arranged between the base and the film. The joint stiffening device of repeatable flexible space suit provided is characterized in that according to the change of the limb strength and bending tendency of the astronaut, the positive or reverse bending state of a plurality of cylindrical air bags in the space joint stiffening device can be changed continuously; adaptability and repeatability of joint stiffening device of space suits is achieved; the problem that the limbs and joints of astronauts in space suits are not easy to bend in the space environment is solved. The plurality of cylindrical air bags in the space joint stiffening device have good elasticity, and can adjust the tightness, and avoid problems such as stiffness of joints and swelling of the limbs due to lack of flexibility in space suits.

Description

technical field [0001] The invention relates to a joint stiffening device for space suits and a method for using the same. Background technique [0002] In the space environment, vacuum, high and low temperature, cosmic radiation, micro meteors, etc. will all cause harm to astronauts. Spacesuits can not only ensure the safety of astronauts, but also provide the necessary working ability for astronauts to complete their tasks. Human blood contains nitrogen, which turns into gas in the space environment and makes the human body expand. Therefore, if an astronaut does not wear a pressurized and airtight spacesuit, he will die due to the huge difference in pressure between the inside and outside. However, due to the high internal pressure in traditional space suits, the bending of astronauts' joints is limited, which makes it difficult for them to flexibly complete work tasks. [0003] At the same time, because the traditional spacesuit has no stiffening device, astronauts nee...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem of the lack of power configuration at the joints of traditional space suits and the difficulty of bending the joints of astronauts' limbs due to the need for pressure balance in the space environment in the space environment, the present invention provides a repeatable flexible space suit based on a columnar inflatable bag.
