Light guide rail component with elastic adapting function

Abstract

The invention relates to a light guide rail component for realizing cabinet and load installation. The guide rail component comprises a guide component, a back insertion component and a power assisting component. The inner wall of a cabinet and the side wall of a load are in slide connection through the guide component, the back of the cabinet and the back of the load are connected through the back insertion component, one end of the power assisting component is connected with the front end of the load, and the other end of the power assisting component is connected with the back of the cabinet. The light guide rail component has advantages that an independent mechanical system is formed by the guide component, the back insertion component and the power boosting component, mounting of thecabinet and the load can be well realized, and a series of effective loads in different standards can be provided with corresponding mechanical and electrical interfaces; besides meeting of upward mechanical conditions, corresponding man-machine ergonomic design is carried out so as to meet the requirement on on-orbit operation of astronauts; in addition, the guide rail component is available foron-orbit reconstruction and supportive to on-orbit mounting, experiments, replacement, repair and maintenance of different effective load units in a full life cycle.

Description

technical field [0001] The invention relates to the technical field of space station equipment, in particular to a light guide rail assembly with elastic adaptation function. Background technique [0002] The existing guide rail components used in space experiment cabinets are all designed to support space station experiment cabinets. The relevant research on space station experiment cabinets is still in its infancy in China; abroad, NASA has developed a series of experiment cabinets and formed international standards ( International Standard Payload Rack, ISPR), in addition, the European Space Agency, Russia and Japan have also developed experimental cabinets similar to the ISPR / ER series with reference to this standard and installed them on the current International Space Station. This type of cabinet is an independent mechanical and thermal control system that can provide corresponding interfaces for a series of large payloads and support sustainable experiments in space....

AI Technical Summary

Problems solved by technology

Because the guide rail assembly of this kind of experimental cabinet is designed in conjunction with the cabinet body, the design basically only supports the uplink mode of the standard unit. As a part of the load, the guide rail assembly is designed to be durable, high bearing capacity, and high support rigidity. However, it occupies a large effective experimental space, has high weight, and poor adaptability seriously restricts the design and development of payloads.
