The invention discloses a flexible installation thermal protection door for an on-satellite remote sensing camera, and belongs to the technical field of on-satellite remote sensing camera design. The thermal protection door comprises a flexible unloading mounting structure, a thermal protection door plate, a thermal protection door plate connecting structure, a thermal door driving mechanism, an unloading spring structure and an electromagnet locking and unlocking structure. One end of the flexible unloading installation structure is clamped between the unloading spring structure and the thermal protection door plate, and the other end of the flexible unloading installation structure is provided with a locking and unlocking structure which is connected with a satellite deck or a camera lens cone. The hot door driving mechanism is connected with the thermal protection door plate through the thermal protection door plate connecting structure and provides driving force for opening and closing of the thermal protection door plate. The thermal protection door has the advantages of being light in weight, high in thermal door temperature stability, high in thermal door connector adaptability and high in thermal protection door reliability.
