Flexible mounting heat shield door for on-board remote sensing camera

Abstract

This invention discloses a flexible thermal protection door for an onboard remote sensing camera, belonging to the field of onboard remote sensing camera design technology. The thermal protection door includes a flexible unloading and mounting structure, a thermal protection door panel, a thermal protection door panel connecting structure, a hotspot drive mechanism, an unloading spring structure, and an electromagnet locking and unlocking structure. One end of the flexible unloading and mounting structure is clamped between the unloading spring structure and the thermal protection door panel, and the other end is equipped with the locking and unlocking structure, which is connected to the satellite module or camera barrel. The hotspot drive mechanism is connected to the thermal protection door panel through the hotspot door panel connecting structure, providing the driving force for the opening and closing of the thermal protection door panel. This invention has the advantages of light weight, high hotspot temperature stability, strong hotspot interface adaptability, and high thermal protection door reliability.
