Abstract

The invention relates to the technical field of spaceflight, in particular to a spacecraft cabin door opening and closing device which comprises a power assisting mechanism and a damping mechanism, wherein the power assisting mechanism and the damping mechanism are fixedly mounted on a cabin body and a cabin door of a spacecraft through pins and hinge supports, and the power assisting mechanism and the damping mechanism are arranged in parallel. Through parallel connection of the power assisting mechanism and the damping mechanism, the spacecraft cabin door can be autonomously and slowly opened, instantaneous impact of residual air pressure in the cabin on the cabin door can be counteracted in the opening process, the cabin door is prevented from being closed too fast in the closing process, operation of astronauts in the cabin leaving process is reduced, and high safety and operability are achieved.

Description

technical field [0001] The present application relates to the field of aerospace technology, in particular, to an opening and closing device for a cabin door of a spacecraft. Background technique [0002] Astronauts will wear space suits before leaving the cabin. Due to time constraints, it is impossible to completely pump the cabin to a vacuum state. Then open the cabin door. There will be a certain amount of residual gas in the cabin, which will be generated during the door opening process. A certain impact will endanger the safety of the astronauts. At the same time, in order to reduce the operation of the astronauts, the hatch needs to be able to automatically open to the specified position. Contents of the invention [0003] The main purpose of this application is to provide a spacecraft door opening and closing device, through the cooperation of the booster mechanism and the damping mechanism, the door is opened, and the impact of the residual air pressure in the cab...
