Description

Technical Field

[0001] The present invention relates to the technical field of cubic satellites, and in particular to a multi-model cubic satellite adaptive separation device. Background Art

[0002] Cubic satellites are low-cost micro-satellites that adopt international standards. The volume of its basic unit (1U) is 10cm×10cm×10cm, and its weight does not exceed 1.33 kg. On this basis, it can be expanded to different sizes of cubic satellites such as "2U", "3U" and even "12U" (20cm×20cm×30cm). The design concept of cubic satellites has greatly reduced the cost of satellite development and promoted the widespread application of commercial off-the-shelf products in the field of cubic satellites;

[0003] With its low cost, short cycle, flexibility and high functional density, CubeSats show broad application prospects in aerospace scientific research and education, commercial applications and other fields;

[0004] After the CubeSat is transported to space by a launch vehicle, it is ejected into a predetermined orbit through a release device.

[0065] Basic principles of the present invention:

[0066] 1U CubeSat launch process:

[0067] like Fig.17 As shown, the driving member 1 41 drives the telescopic shaft 411 to contract, and drives the release bin 6 to move toward the storage device 1 through the connecting rod 412. When the release bin 6 moves to a certain position, the electric baffle 13 contracts, the elastic rod 12 extends, and the cubic satellite 1 2 is pushed into the release bin 6 through the push plate 11. As the cubic satellite 1 2 enters the release bin 6, the cubic satellite 1 2 squeezes the block 61, and the block 61 is contracted by compressing the elastic rod 9 611; after the cubic satellite 1 2 enters the release bin 6, the block 61 loses its restriction, the elastic rod 9 611 extends, the block 61 limits the cubic satellite 1 2 inside the release bin 6, and the electric baffle 13 extends to limit the card slot 21 of the cubic satellite 2 3 (2U cubic satellite) to prevent subsequent cubic satellites from entering the release bin 6;

[0068] like Fig.18 As shown, the driving member 1 41 drives the telescopic shaft 411 to extend, and drives the release chamber 6 to move in the opposite direction of the storage device 1 through the connecting rod 412. After the release chamber 6 is restored, the ejection plate 51 of the ejection device 5 ejects the cube satellite 1 2 to the predetermined orbit;

[0069] 2U CubeSat launch process:

[0070] like Fig.19 As shown, the driving member 1 41 drives the release bin 6 to move toward the storage device 1, and the push plate 11 pushes the CubeSat 2 3 into the release bin 6, so that the telescopic plate 66 is extended, and the elastic rod 11 661 is stretched, and then the block 61 limits the CubeSat 2 3 in the release bin 6, and the electric baffle 13 limits the remaining satellites in the storage device 1;

[0071] like Fig. 20 As shown, when the release bin 6 carrying the CubeSat 2 3 moves in the opposite direction toward the storage device 1, the telescopic plate 66 squeezes the push block 3 46, driving the telescopic tube 3 462 to extend, so that the ejection device 5 moves to one side and compresses the elastic rod 8 54; the ejection plate 51 of the ejection device 5 contracts, making the ejection device 5 more elastic, thereby completing the release of the CubeSat 2 3;

[0072] During the movement of the release chamber 6, the limit slot 65 enters the limit rod 421 of the rotating rod 42;

[0073] During the movement of the release chamber 6, the control column 436 of the control block 435 inside the base 4 enters the control column slot 663 of the telescopic plate 66, driving the control block 435 to move to one side, compressing the elastic rod 3 437. At this time, the fixed block 1 443 is inside the fixed slot 1 432, the control rod 43 cannot move, and the elastic rod 2 434 is extended;

[0074] like Fig.21 As shown, when the control block 435 moves to the limit, the push block 1 44 is compressed, the telescopic tube 1 442 is extended, the fixed block 1 443 is driven to move upward, the elastic rod 444 is compressed, the fixed block 1 443 loses the restriction on the fixed groove 1 432, and the control rod 43 moves toward the control block 435 under the action of the elastic rod 2 434. When the control rod 43 moves to a certain extent, the fixed block 2 455 will move downward into the fixed groove 2 433 under the action of the elastic rod 6 456, and limit the control rod 43 to prevent the control rod 43 from recovering under the action of the elastic rod 3 437.

[0075] As the control rod 43 moves, the gear 422 is driven to rotate through the rack 431, thereby driving the rotating rod 42 to rotate. At this time, the limiting clamping rod 421 is combined with the limiting clamping groove 65, driving the release bin 6 to rotate, and the connecting rod 412 is separated from the connecting groove 64;

[0076] like Fig. 22 As shown, when the release chamber 6 is turned over, the push block 47 loses its restriction, the elastic rod 7 474 extends, and drives the fixed block 3 473 to enter the limiting groove 56 of the limiting rod 55, thereby limiting the ejection device 5 and increasing the stability of the ejection release process;

[0077] Since the ejection device 5 is limited, the length of the telescopic tube 3 462 is fixed, and the push block 3 46 cannot be restored, when the release chamber 6 is turned over, the push block 3 46 will enter the interior of the release chamber 6 through the notch of the release chamber 6, and will not interfere with the turning of the release chamber 6;

[0078] The release chamber 6 stops after rotating 90 degrees, and the squeezing block 48 of the base 4 squeezes the pushing block 5 615, driving the telescopic tube 5 613 to extend, thereby driving the moving plate 612 to move to one side, and the block 61 loses the restriction on the CubeSat 2 3, and the ejection device 5 ejects and releases the CubeSat 2 3;

[0079] like Fig.23 As shown, after the release of the cubic satellite 2 3 is completed, the telescopic plate 66 is restored under the action of the elastic rod 11 661. When the telescopic plate 66 moves upward, it will compress the push block 2 45 on the inner wall of the base 4, drive the telescopic tube 2 452 to extend, drive the moving block 453 to move upward, and compress the elastic rod 5 454. As the moving block 453 moves upward, it drives the fixed block 2 455 and the elastic rod 6 456 to move upward. The fixed block 455 will extend from the fixed groove 2 433 and lose the restriction on the control rod 43. The control rod 43 and the control block 435 will move to one side under the action of the elastic rod 3 437, and drive the gear 422 to rotate in the opposite direction through the rack 431. Through the cooperation of the limit clamping rod 421 and the limit clamping groove 65, the release chamber 6 is driven to flip in the opposite direction (restore).

[0080] When the release chamber 6 is turned over in the opposite direction, the connection groove 64 of the release chamber 6 is reconnected with the connection rod 412;

[0081] When the release chamber 6 turns over in the opposite direction, the release chamber 6 compresses the push block 47, drives the telescopic tube 472 to extend, and mobilizes the fixed block 3 473 to move upward. The fixed block 3 473 loses the restriction on the limit groove 56, and the elastic device 5 recovers under the action of the elastic rod 8 54, and the ejection device 5 moves to the initial position, and the push block 3 46 recovers;

[0082] By repeating the above movements, adaptive adjustment and release of different models (i.e., 1U and 2U cubic satellites) can be completed, which reduces the use of electronic components, reduces the failure rate, and increases the stability of release.
