The invention discloses a lower tray structure of an aluminum alloy box. The lower tray structure comprises a bottom plate assembly; a middle beam which is fixedly arranged on the bottom plate assembly; a frame assembly which is fixedly arranged on the periphery of the bottom plate assembly in a surrounding mode.; and supporting bases which are fixedly arranged on the inner ring wall surface of the frame assembly in a bilateral symmetry manner, wherein the middle beam is distributed in the width direction of the bottom plate assembly, positioning grooves are formed in the supporting bases, andthe two opposite ends of the middle beam are fixedly arranged in the positioning grooves respectively. With application of the mode, the lower tray structure of the aluminum alloy box is good in structural strength and has the advantages of being simple in structure, stable, reliable and long in service life.
