Example Embodiment
[0025] In order to make the solution of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0026] like Figure 1~3 As shown, a micro-satellite structure suitable for optical loads, including a bottom plate 1, a middle plate 2, a top plate 3, a side plate 4, a bracket 5, a bulkhead 6, a bottom plate strengthening embedded part 7, a docking ring 8 and a load 9; the bottom plate 1. The middle plate 2, the top plate 3 and the side plate 4 all adopt a rectangular plate structure. The bottom plate reinforcement embedded parts 7 for reinforcing the structure are embedded in the bottom plate 1, and the bracket 5 for supporting the load 9 is installed on the upper surface of the bottom plate 1. The bottom surface of the bottom plate 1 is equipped with a docking ring 8; the middle plate 2 and the top plate 3 are provided with through holes for passing through the load 9; Connecte...

The invention discloses a microsatellite structure suitable for an optical load. The structure comprises a bottom board, an intermediate board, a top board, side boards, supports, separation frames, abottom board reinforcing embedded part, a docking ring and the load. The bottom board, the intermediate board, the top board and the side boards are each of a rectangular board structure. The bottomboard reinforcing embedded part used for reinforcing the structure is pre-buried in the bottom board. The supports used for supporting the load are installed on the upper surface of the bottom board.The docking ring is installed on the lower surface of the bottom board. Through holes allowing the load to penetrate through are formed in the intermediate board and the top board. The bottom board, the intermediate board and the top board are parallel, and the edges of the bottom board, the intermediate board and the top board are perpendicularly and fixedly connected with the four side boards toform a box-type structure. The multiple separation frames used for reinforcing the rigidity are installed between the bottom board and the intermediate board. Through cooperation of the bottom board,the intermediate board, the top board, the side boards, the supports, the separation frames, the bottom board reinforcing embedded part, the docking ring and the load, the force transferring path ofthe optical load is shortened, the structural layout of a whole microsatellite is optimized, and the defects that parts of a traditional microsatellite truss structure are concentrated, and the mass is large are overcome.
Description
technical field [0001] The invention relates to a micro-satellite structure suitable for optical loads, in particular suitable for micro-satellites with an optical load of 50-100 kg, and belongs to the technical field of micro-satellite load assembly structures. Background technique [0002] Compared with traditional satellites, the microsatellite structure has the characteristics of small space, more equipment, high density, and high integration. Due to the space requirements of optical load microsatellites, the density of equipment in the satellite is higher. At the same time, the ratio of optical load to the weight of the whole star is relatively large, and the load is relatively concentrated. [0003] At present, microsatellites (such as CubeSat, etc.) generally adopt a metal truss structure, using metal plates to provide equipment mounting surfaces, and hollowing out appropriate parts to reduce weight to form a single truss, and several truss structures are combined to ...
