Impact-reducing support structure suitable for single machine with small heat conduction amount requirement on spacecraft

The invention relates to an impact reducing support structure suitable for a single machine with a small heat conduction amount requirement on a spacecraft, and belongs to the technical field of impact reduction support structures. The impact reducing support structure comprises an upper fastening device, an impact reducing support, a lower fastening device and a connecting embedded part. The impact reducing support provides a threaded mounting hole for the single machine; a single machine mounting foot is a through hole and is connected with the single machine through a fastening screw and apressing gasket; a support interface, connected with the single machine, of the impact reducing support adopts an eccentric design; the connecting embedded part is arranged in a cellular board and provides a threaded mounting hole for the impact reducing support, and the mounting hole of the impact reducing support and the mounting hole of the cellular board are through holes and the impact reducing support and the cellular board are connected with the single machine through fastening screws and pressing gaskets. According to the impact reducing support structure, the step-by-step impact reduction mode is adopted, and the impact reduction efficiency is high; the upper support interface adopts an eccentric design, so that the bearing capacity is high; the impact reducing support is of a cylindrical hollow shell structure, and has the advantage of being low in structural weight and wide in application range.
