Satellite load cabin structure

The invention provides a satellite load cabin structure and belongs to the technical field of spacecraft structures. The satellite load cabin structure comprises a main body structure and a truss supporting structure. The main body structure comprises a top plate, a bottom plate and a plurality of side supporting plates arranged between the top plate and the bottom plate; the truss supporting structure comprises a plurality of truss rods and a plurality of joints; the multiple joints are connected with the top plate or the bottom plate; at least every two truss rods are fixed to the corresponding joint; and the multiple truss rods are connected into an integrated structure through the joints. The satellite load cabin structure is suitable for mounting of a large load part on a satellite through a plurality of large-span dispersed mounting points, and meanwhile avoiding mounting of the large load part on one side of the satellite can be met.
