Description

Technical Field

[0001] This invention relates to the field of aerospace satellite technology, and specifically to an integrated irregularly shaped unfolding structure for aerospace satellites. Background Technology

[0002] A spaceborne synthetic aperture radar (SAR) satellite is a modern radar satellite capable of acquiring high-level information about ground targets around the clock and in all weather conditions. A SAR satellite is mainly composed of a satellite body, solar panels, and radar antennas, with the radar antenna being the largest part of the entire satellite in terms of effective volume.

[0003] Currently, SAR radar antennas can be divided into bulk-mounted (non-deployable) and collapsible-deployable types according to their deployment method. To ensure radar performance, synthetic aperture radar satellites usually require a large antenna size. Therefore, collapsible-deployable antennas are often used to both increase the antenna size and reduce the size during transmission. However, the existing collapsible-deployable antennas are usually simply folded on the outside of the satellite. Repeated folding on a single surface will increase the envelope area on the outside of the satellite, thereby increasing the size of the outer cover and increasing manufacturing costs. In addition, most antennas rely on their own elasticity to deploy automatically, which may lead to deployment failures such as jamming. Summary of the Invention

[0004] Therefore, this invention was made in view of the above problems. The purpose of this invention is to unfold the push antenna panel located at the bottom of the satellite by means of the cooperation between the satellite, unfolding mechanism one, and unfolding mechanism two, so as to solve the problem that the antenna has a large envelope area due to being folded on the outside of the satellite and that it will malfunction when unfolded by relying on the elasticity of the antenna itself.

[0015] Beneficial effects of this invention:

[0016] 1. The satellite's built-in motor drives the push rod in the deployment mechanism to rotate. The rotation of the push rod pushes the stacked antenna panels, allowing the antenna panels located on different horizontal planes to be deployed simultaneously. Finally, the push rod in the second deployment mechanism is used to horizontally align the antenna panels at both ends, thus successfully completing the antenna panel deployment process. This can greatly reduce the satellite's outer envelope area, thereby reducing launch costs.

[0017] 2. The antenna panel is unfolded by pushing a push rod, which ensures reliable unfolding and reduces unfolding failures. Attached Figure Description

The invention can also be implemented in various other forms, and therefore is not limited to the embodiments described below. Furthermore, for clarity, components not connected to the invention will be omitted from the drawings;

[0052] like Figure 1 , 2 As shown, an integrated irregularly shaped deployment structure for aerospace satellites includes: satellite 100, deployment mechanism one 200, deployment mechanism two 300, and cover plate 400.

[0053] like Figure 3 As shown, the satellite 100 includes: a circular partition 110, a motor 120, and a shell 130;

[0054] The circular partition 110 is mounted on the housing 130 and is used for limiting movement.

[0055] The motor 120 is located below the circular partition 110. The motor 120 is rotatably connected to the circular partition 110. The motor 120 provides power. The upper half of the motor shaft of the motor 120 is threaded.

[0057] The limiting circular hole 131 is located in the middle of the main body of the housing 130. The circular partition 110 and the motor 120 are fixedly installed inside the limiting circular hole 131, and the limiting circular hole 131 serves to limit the motor 120.

[0058] The semicircular track 132 is located on one side of the limiting circular hole 131, and the semicircular track 132 plays a guiding role.

[0059] like Figure 5 , 6 As shown, the second semicircular track 133 is located on one side of the limiting circular hole 131. The height of the second semicircular track 133 is half that of the first semicircular track 132. The second semicircular track 133 plays a guiding role.

[0060] The transverse ejection track 134 is located on one side of the limiting circular hole 131, and the transverse ejection track 134 plays a guiding role.

[0061] The stacking area 135 is located on one side of the limiting hole 131, and the stacking area 135 serves to store the limiting function.

[0062] The sliding track 136 is located on one side of the stacking area 135, and the sliding track 136 serves as a guide;

[0063] like Figure 7 As shown, the unfolding mechanism 200 includes: a limiting plate 210, an antenna panel 220, and a push rod 230;

[0064] The limiting plate 210 is installed at the stacking area 135. The limiting plate 210 can move up and down relative to the stacking area 135. A spring is installed on the top of the limiting plate 210.

[0065] The antenna panel 220 is located below the limiting plate 210. The antenna panel 220 is installed in the stacking area 135. Four antenna panels 220 are stacked downwards (the number depends on the situation). The antenna panel 220 rotates around the motor 120 and is finally pushed out laterally through the horizontal push-out track 134. The thickness of the antenna panel 220 is the same as the height of the semicircular track 132. Half of the thickness of the antenna panel 220 is the height of the semicircular track 133. When the antenna panel 220 rotates to the semicircular track 133, the antenna panel 220 will be limited by the semicircular track 133, so that the antenna panel 220 will no longer rotate.

[0066] like Figure 8 As shown, the antenna panel 220 includes: a T-shaped limiting protrusion 221, a T-shaped limiting groove 222, and a limiting hole 223;

[0067] The T-shaped limiting protrusion 221 is located at one end of the main body of the antenna panel 220. The T-shaped limiting protrusion 221 serves as a connector. The T-shaped limiting protrusion 221 is tangent to the semicircular track 132 and the semicircular track 133. The semicircular track 132 and the semicircular track 133 limit the antenna panel 220.

[0068] The T-shaped limiting groove 222 is located at the other end of the main body of the antenna panel 220, and the T-shaped limiting groove 222 is connected to the T-shaped limiting protrusion 221 on another antenna panel 220.

[0069] The limiting hole 223 is located on both sides of the T-shaped limiting groove 222, and the limiting hole 223 plays a limiting role;

[0070] like Figure 7 As shown, the push rod 230 is mounted on the motor 120. The push rod 230 pushes the antenna panel 220 to rotate. The thickness of the push rod 230 is half the thickness of the antenna panel 220. The push rod 230 is not blocked by the semicircular track 133. The push rod 230 can rotate 360°.

[0071] like Figure 9 As shown, the push rod 230 includes: a circular hole 231 and an outer circumferential surface 232;

[0072] The circular hole 231 is fixedly connected to the motor shaft of the motor 120, and the motor 120 drives the push rod 230 to rotate.

[0073] The outer circumferential surface 232 is located around the circular hole 231. The outer circumferential surface 232 is tangent to the circumferential surface where the T-shaped limiting groove 222 is located. The outer circumferential surface 232 limits the circumferential surface where the T-shaped limiting groove 222 is located, so that the antenna panel 220 rotates along the correct track.

[0074] like Figure 10 , 11 As shown, the second deployment mechanism 300 is located on the side of the first deployment mechanism 200 away from the satellite 100, and the other side of the second deployment mechanism 300 is provided with a cover plate 400. The second deployment mechanism 300 includes: a limiting frame 310, an adhesive plate 320, a second limiting plate 330, a second antenna panel 340, and a second push rod 350.

[0075] like Figure 12 , 13 As shown in Figure 14, the limiting frame 310 includes: push rod notch 311, semi-circular track three 312, semi-circular track four 313, transverse push-out track two 314, stacking area two 315, round hole two 316, and positioning pin one 317.

[0076] The push rod notch 311 is located in the middle of the limit frame 310, and the push rod notch 311 allows the push rod 350 to pass through without obstruction.

[0077] The semicircular track 312 is located on one side of the push rod notch 311. The height of the semicircular track 312 is the same as that of the semicircular track 132. The semicircular track 312 serves to guide the antenna panel 120 and the limiting plate 230.

[0078] The semicircular track 4 313 is located on the other side of the push rod notch 311. The height of the semicircular track 4 313 is the same as that of the semicircular track 2 133. The semicircular track 4 313 serves to guide the antenna panel 1 220 and the limiting plate 2 330.

[0079] The second lateral push-out track 314 is located on one side of the push rod notch 311. The second lateral push-out track 314 serves to guide the first antenna panel 220 and the second limiting plate 330.

[0080] The stacking area 2 315 is located on one side of the push rod notch 311, and the stacking area 2 315 serves to store the limiting antenna panel 1 220 and the limiting plate 2 330.

[0081] The second round hole 316 is located below the limiting frame 310, and the second round hole 316 serves to store the first positioning pin 317.

[0082] The positioning pin 317 is installed on the round hole 316, and a spring is installed on the positioning pin 317. The lower end of the positioning pin 317 cooperates with the limiting hole 223 for limiting.

[0083] like Figure 10 As shown, the adhesive plate 320 is bonded to the limiting frame 310, and the adhesive plate 320 can be separated from the limiting frame 310 when it is squeezed.

[0084] like Figure 11 As shown, the second limiting plate 330 is located below the first antenna panel 220, and three first antenna panels 220 are arranged above the second limiting plate 330.

[0085] like Figure 15 As shown, the second antenna panel 340 includes: a second T-shaped limiting protrusion 341, a limiting plate 342, a protruding baffle 343, and a second limiting hole 344.

[0086] The second T-shaped limiting protrusion 341 is located at one end of the main body of the second antenna panel 340, and the second T-shaped limiting protrusion 341 is connected to the T-shaped limiting groove 222 on the first antenna panel 220.

[0087] The limiting plate 342 is located at the other end of the main body of the antenna panel 340, and the protruding baffle 343 is located on one side of the limiting plate 342. The limiting plate 342 and the protruding baffle 343 serve to limit the push rod 350.

[0088] The second limiting hole 344 is located on both sides of the limiting plate 342, and the second limiting hole 344 plays a limiting role;

[0089] like Figure 16 As shown, the second push rod 350 includes: a third circular hole 351, an adhesive ring 352, a second outer circumferential surface 353, an annular notch 354, and a limiting groove 355;

[0090] The three circular holes 351 are connected to the motor shaft of the motor 120 by threads. The adhesive ring 352 is fixedly installed below the three circular holes 351. The inner ring of the adhesive ring 352 is bonded to the motor shaft of the motor 120, which temporarily prevents the push rod 350 from moving up and down relative to the motor 120, so that the push rod 350 rotates with the motor 120.

[0091] The outer circumferential surface 2 353 is located around the circular hole 351. The outer circumferential surface 2 353 is tangent to the T-shaped limiting groove 222. The outer circumferential surface 2 353 limits the circumferential surface where the T-shaped limiting groove 222 and the limiting plate 342 are located, so that the antenna panel 1 220 and the antenna panel 2 340 rotate along the correct track.

[0092] The annular notch 354 is located in the middle of the outer circumferential surface 353. The annular notch 354 can accommodate the limiting plate 342, so that the outer circumferential surface 353 can limit the circumferential surface where the limiting plate 342 is located.

[0093] The limiting groove 355 is located at one end of the push rod 350, and the limiting groove 355 cooperates with the limiting plate 342 to limit the movement.

[0094] like Figure 17 As shown, the cover plate 400 includes: a limiting hole 3 410 and a positioning pin 2 420;

[0095] The limiting hole 3 410 is located at one end of the main body of the cover plate 400, and the limiting hole 3 410 serves to store the positioning pin 2 420.

[0096] The second positioning pin 420 is installed in the third limiting hole 410. A spring is installed on the second positioning pin 420. The lower end of the second positioning pin 420 cooperates with the first limiting hole 223 and the second limiting hole 344 for limiting.

[0097] Working principle of this invention:

[0098] Initial state as Figure 2 As shown, after the satellite launch is successful, motor 120 is started. The motor shaft on motor 120 drives push rod 350 and push rod 230 to rotate. The rotation of push rod 350 and push rod 230 pushes antenna panel 220, as shown. Figure 18 As shown, in the second unfolding mechanism 300, the circumferential surface of the T-shaped limiting groove 222 on the first antenna panel 220 is limited by the outer circumferential surface 353, and the outer circumferential surface of the T-shaped limiting protrusion 221 is limited by the semicircular track 312, so that the first antenna panel 220 can rotate around the motor 120, as shown. Figure 19 As shown, in the unfolding mechanism 200, the circumferential surface of the T-shaped limiting groove 222 on the antenna panel 220 is limited by the outer circumferential surface 232, and the outer circumferential surface of the T-shaped limiting protrusion 221 is limited by the semicircular track 132, allowing the antenna panel 220 to rotate around the motor 120. The push rods 250 and 230 continue to rotate, respectively pushing the antenna panel 220 to continue rotating until one side of the antenna panel 220 is blocked by the semicircular track 313 and 133, respectively, preventing the antenna panel 220 from rotating further (e.g., ...). Figure 20 , 21 As shown), push rod 250 and push rod 230 continue to rotate, pushing antenna panel 220 outward along horizontal extension track 214 and horizontal extension track 134 respectively. When antenna panel 220 moves to the designated position (e.g. Figure 22 , 23As shown), the antenna panels 220 are positioned by positioning pins 317 and 420 respectively, allowing them to connect smoothly. Push rods 350 and 230 continue to rotate, passing through semicircular tracks 313 and 133 respectively, returning to their initial positions. At this point, due to the spring force of limiting plates 330 and 210, the antenna panels 220 stacked in stacking areas 315 and 135 automatically fill in the gaps. Push rods 350 and 230 continue to rotate, pushing the antenna panels 220 to connect with the already deployed antenna panels 220 (e.g., ...). Figure 24 As shown), the T-shaped limiting protrusion 221 connects with the T-shaped limiting groove 222 during rotation, and the above process is repeated, ultimately allowing the four stacked antenna panels 220 to be fully unfolded (as shown). Figure 25 As shown), the unfolding mechanism 200 unfolding process is complete, as follows: Figure 26 , 27 As shown, when the second push rod 350 pushes the last antenna panel 220 out, the limiting groove 355 gradually coincides with the limiting plate 342, as... Figure 28 , 29 As shown, the limiting groove 355 has completely overlapped with the limiting plate 342. At this time, the second push rod 350 is still rotating, but it is restricted by the protruding baffle 343. Ultimately, the adhesive ring 352 and the motor 120 are disconnected, and the motor 120 continues to rotate. Since the motor 120 and the second push rod 350 are connected by threads, when the second push rod 350 is restricted and cannot rotate, the rotation of the motor 120 drives the second push rod 350 to move downward. Due to the cooperation between the limiting groove 355 and the limiting plate 342, the second push rod 350 drives the second antenna panel 340 and the first antenna panel 220 to move downward together (as shown). Figure 30 As shown), antenna panel 2 340 moves downwards, pressing the adhesive plate 320, causing the adhesive plate 320 to break its bond with the limiting frame 310. When antenna panel 2 340 and antenna panel 1 220 move along the sliding track 136 to the same horizontal position as antenna panel 1 220 on the other side, the motor 120 stops rotating. Figure 31 As shown, the first unfolding mechanism 200 and the second unfolding mechanism 300 have now been fully unfolded.
