This invention discloses a lightweight structure for a laser-radio integrated communication payload for microsatellites, belonging to the field of satellite payload lightweighting technology. The invention includes a mirror body and a substrate. Multiple honeycomb holes are evenly distributed on the back of the mirror body, and triangular ribs are provided at the intersections of these holes. A support ring is fitted to the outer edge of the mirror body, and three positioning holes and nine mounting holes are evenly distributed on the outer surface of the support ring. By evenly distributing hexagonal honeycomb holes on the back of the mirror body, the weight of the mirror body is significantly reduced. By using novel lightweight materials for the mirror body, substrate, and support, the thermal stability of the primary mirror structure is improved while maintaining structural rigidity. This reduces surface distortion while significantly compressing the weight of the primary mirror structure, achieving further optimization compared to traditional lightweighting solutions. This results in the optimization of the satellite payload structure for extreme lightweighting, ultra-stable thermal performance, and high dynamic rigidity.
