Description

Technical Field

[0001] This application relates to the field of aerospace solar panels, and in particular to a satellite solar panel deployment device. Background Technology

[0002] Solar panels are devices that convert solar energy into electrical energy. Almost all spacecraft rely on solar energy as their primary energy source. To enable spacecraft to operate for extended periods, solar panels must be deployed. Therefore, mechanisms for deploying solar panels are crucial in the aerospace field.

[0003] Before launch, several release mechanisms are typically used to fold and press the solar panels onto the satellite body. However, the reliability of the pressing and release mechanisms is very important. If the cutter fails or any pyrotechnic circuit fails, causing the cutter to fail to detonate, the solar panels cannot be deployed normally, and power cannot be supplied to the equipment inside the satellite, resulting in the satellite not being able to work properly. Summary of the Invention

[0004] The purpose of this application is to provide a satellite solar panel deployment device.

[0005] The satellite solar panel deployment device provided in this application adopts the following technical solution:

[0006] A satellite solar panel deployment device includes a first mounting plate and a second mounting plate. Both the first and second mounting plates are square and arranged parallel to each other. A connecting plate is provided on both the first and second mounting plates to connect them. A connecting rod for connecting the satellite body is fixedly connected to the first mounting plate. Fixed solar panels are fixedly connected to the opposite sides of the first and second mounting plates. A drive gear is provided inside the first mounting plate. A drive motor for driving the drive gear is provided on the satellite body. Four sliding grooves are formed on the first mounting plate, each groove being arranged along the angle of the first mounting plate's planar projection. Four movable solar panels are arranged between the first and second mounting plates. The fixed solar panels are parallel to the movable solar panels, and the four movable solar panels are all located in the same plane and abut against each other in a matrix configuration. A connecting component is provided inside the first mounting plate to allow the movable solar panels to slide along the sliding grooves towards the opposite sides under the action of the drive gear.

[0007] By adopting the above technical solution, when it is necessary to deploy the solar panels, the drive motor can be started to drive the four mobile solar panels to move along the slide to the corner of the first mounting plate through the connecting components, thereby quickly deploying the four mobile solar panels. In this way, the four mobile solar panels are driven to deploy along the slide by the drive gear. Not only is the structure simple and reliable, and the purpose of deploying satellite solar panels can be achieved, but the four mobile solar panels can also be deployed through independent slides, which improves the adaptability of the device.

[0008] Optionally, the first mounting plate has four mounting slots communicating with the slide groove, all located on the same side of the slide groove. The connecting assembly includes four driven gears equidistantly arranged around the axis of the driving gear. The driven gears are located at the ends of the mounting slots near the driving gear. A first rotating column is rotatably connected within the mounting slot, passing through the driven gear. The first rotating column is coaxially arranged and fixedly connected to the driven gear. A first driven wheel is fixedly connected to the first rotating column, and the first driven wheel is coaxially arranged with the driven gear. Each mounting slot is equipped with a second driven wheel, which is located at the end of the mounting slot away from the driving gear. A second rotating column is rotatably connected to the mounting slot. The second driven wheel is fixed to the second rotating column and is coaxially arranged with the second rotating column. A conveyor belt for connecting the second driven wheel and the first driven wheel in the same mounting slot is provided. The conveyor belt is arranged along the mounting slot. A slider is fixed to the conveyor belt and is slidably connected to the slide groove. The end of the slider away from the bottom of the slide groove is fixed to the movable solar panel.

[0009] By adopting the above technical solution, when the drive motor drives the active gear to rotate, the active gear can simultaneously drive the four driven gears to rotate, thereby causing the transmission belt between the first driven wheel and the second driven wheel to drive the slider to move along the slide groove, thereby causing the four mobile solar panels to move along the slide groove to the side away from each other, thus enabling the mobile solar panels to deploy quickly.

[0010] Optionally, a limiting groove is formed on the side wall of the slide away from the mounting groove, and a limiting rod is fixed to the side of the slider away from the conveyor belt, with the end of the limiting rod away from the conveyor belt placed in the limiting groove.

[0011] By adopting the above technical solution, the position of the limiting rod can be restricted by the limiting groove, thereby improving the stability of the slider sliding in the groove.

[0012] Optionally, the limiting rod is provided with a pulley, which is slidably connected in the limiting groove.

[0013] By adopting the above technical solution, the resistance encountered by the limiting rod when sliding in the groove can be reduced, and the stability of the slider when sliding in the groove can be further improved.

[0014] Optionally, multiple positioning grooves are provided at each of the four corners of the second mounting plate. The positioning grooves are located on the side of the second mounting plate closer to the first mounting plate, and a positioning rod is provided in the positioning groove. A spring is fixed between the end of the positioning rod near the bottom of the positioning groove and the bottom of the positioning groove. The end of the positioning rod away from the second mounting plate abuts against the side wall of the movable solar panel. A positioning hole is provided on the upper plate of the movable solar panel. When the slider slides the end of the slide groove near the edge of the mounting plate, the positioning rod is inserted into the positioning hole.

[0015] By adopting the above technical solution, when the mobile solar panel is deployed, the positioning rod can be inserted into the positioning hole under the action of the spring, thereby fixing the position of the mobile solar panel and improving the stability of the solar panel when it is deployed.

[0016] Optionally, the opening of the positioning groove is set to be arc-shaped and the spring is in close contact with the inner wall of the positioning groove.

[0017] By adopting the above technical solution, the direction of spring contraction or extension can be restricted, thereby improving the stability of the positioning rod.

[0018] Optionally, a locking groove is provided on the side wall of the slide near the edge of the first mounting plate. A threaded rod is rotatably connected in the locking groove. The axis of the threaded rod is parallel to the axis of the drive gear. A threaded cylinder is externally threaded to the threaded rod. The threaded cylinder is rectangular in shape, and one end of the threaded cylinder away from the threaded rod passes through the first mounting plate and is slidably connected to the first mounting plate. A positioning gear is fixedly connected to the side wall of the threaded rod. The positioning gear is coaxially arranged with the threaded rod. A rack is fixedly connected to the slider. When the slider moves to the locking groove side, the rack meshes with the positioning gear. A sliding hole is provided on the movable solar panel for the threaded cylinder to pass through. An insertion groove is provided on the side wall of the second mounting plate near the first mounting plate. When the slider moves to the end of the slide near the corner of the first mounting plate, the threaded cylinder passes through the sliding hole and is inserted into the insertion groove.

[0019] By adopting the above technical solution, when the slider moves along the slide groove to the locking groove side, the rack on the slider meshes with the positioning gear, which in turn drives the threaded rod to rotate. This causes the threaded cylinder on the threaded rod to pass through the slider and be inserted into the insertion groove on the second mounting plate, thereby fixing the position of the moving solar panel and improving the stability of the panel.

[0020] Optionally, the cross-section of the sliding hole on the side closer to the first mounting plate is larger than the cross-section of the sliding hole on the side farther from the first mounting plate.

[0021] By adopting the above technical solution, since the threaded cylinder gradually rises under the drive of the positioning gear, the opening area of ​​the sliding hole can be reduced, thereby increasing the area of ​​the mobile solar panel that receives light energy.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By starting the drive motor, the drive motor can drive the four mobile solar panels to move along the slide to the corner of the first mounting plate through the connecting components, thereby quickly unfolding the four mobile solar panels. In turn, the four mobile solar panels are unfolded along the slide through the drive gear. This not only has a simple and reliable structure and can achieve the purpose of satellite solar panel unfolding, but also the four mobile solar panels can be unfolded through independent slides, which improves the adaptability of the device.

[0024] 2. The driving gear can simultaneously drive four driven gears to rotate, which in turn causes the transmission belt between the first driven sprocket and the second driven wheel to drive the slider to move along the slide, thereby enabling the four mobile solar panels to move along the slide to the side away from each other, thus enabling the mobile solar panels to deploy quickly.

[0025] 3. After the mobile solar panel is deployed, the positioning rod can be inserted into the positioning hole under the action of the spring, thereby fixing the position of the mobile solar panel and improving the stability of the solar panel when it is deployed. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be described in further detail below. Example 1

[0037] A satellite solar panel deployment device, referring to Figure 1 It includes a first mounting plate 1, a second mounting plate 2 on one side of the first mounting plate 1, the first mounting plate 1 and the second mounting plate 2 are parallel to each other and opposite to each other, a connecting plate 15 for connecting the two is fixedly connected between the first mounting plate 1 and the second mounting plate 2, and a fixed solar panel is fixedly connected to the side of the first mounting plate 1 and the second mounting plate 2 that is far away from each other. The fixed solar panel is not shown in the figure.

[0038] Reference Figure 1 and Figure 2 A cavity 3 is provided in the center of the first mounting plate 1, and a drive gear 13 is provided in the cavity 3. A drive motor 16 for driving the drive gear 13 is provided on the side of the first mounting plate 1 away from the second mounting plate 2. The output shaft of the drive motor 16 passes through the side wall that fixes the solar panel and the first mounting plate 1 and is fixedly connected to the drive gear 13. The output shaft of the drive motor 16 is coaxial with the drive gear 13. Two connecting rods for connecting the satellite body are fixedly connected on the first mounting plate 1. The drive motor 16 is located between the two connecting rods, and the connecting rods are not shown in the figure.

[0039] Reference Figure 1 , Figure 2 and Figure 3The first mounting plate 1 has four sliding grooves 11, which are arranged diagonally along the first mounting plate 1. One end of the sliding groove 11 is connected to the cavity 3, and the other end of the sliding groove 11 is located at the corner of the first mounting plate 1. A mounting groove 12 is provided on one side wall of the sliding groove 11, located on the same side as the sliding groove 11 and connected to the sliding groove 11. A connecting assembly 5 is provided in the mounting groove 12. The connecting assembly 5 includes a first rotating column 54 located at one end of the mounting groove 12 near the driving gear 13. The first rotating column 54 is rotatably connected in the mounting groove 12. A driven gear 51 is fixedly connected to the first rotating column 54, passing through the driven gear 51 and coaxially arranged with the driven gear 51. The driven gear 51 is fixedly connected to the first rotating column 54. The four driven gears 51 are equidistantly arranged around the axis of the driving gear 13 and mesh with the driving gear 13.

[0040] A first driven wheel 52 is fixedly connected to the first rotating column 54. The first driven wheel 52 is coaxially arranged with the driven gear 51. A second rotating column 57 is provided at the end of the mounting groove 12 away from the driving gear 13. The second rotating column 57 is rotatably connected in the mounting groove 12. A second driven wheel 53 is fixedly connected to the second rotating column 57. The second driven wheel 53 is coaxially arranged with the second rotating column 57. A transmission belt 55 for connecting the first driven wheel 52 and the second driven wheel 53 is sleeved between them. A connecting block 564 is fixedly connected to the side of the transmission belt 55 near the slide groove 11. A slider 56 is fixedly connected to the end of the connecting block 564 away from the transmission belt 55. The slider 56 is slidably connected in the slide groove 11. A movable solar panel 4 is fixedly connected to the end of the slider 56 away from the slide groove 11. The four movable solar panels 4 are all located in the same plane and arranged in a matrix, with their adjacent corners abutting each other.

[0041] When the drive motor 16 is started, it drives the drive gear 13 to rotate. The drive gear 13 then drives the driven gear 51, which meshes with the drive gear 13, to rotate. At the same time, the driven gear 51 drives the first rotating column 54 to rotate. The first rotating column 54 drives the first driven wheel 52 to rotate. Simultaneously, the second rotating column 57 and the second driven wheel 53 begin to rotate. As a result, the conveyor belt 55 drives the slider 56 to slide along the slide groove 11. Thus, the slider 56 drives the movable solar panels 4 to slide along the direction of the slide groove 11. Therefore, starting the drive motor 16 can make the four movable solar panels 4 slide simultaneously to the side that is far away from each other.

[0042] To improve the stability of the slider 56 sliding along the slide groove 11, a limiting groove 14 is formed on the side wall of the slide groove 11 away from the mounting groove 12. The limiting groove 14 is set along the slide groove 11. Two limiting rods 561 are fixedly connected to the side of the slider 56 away from the connecting block 564. The ends of the two limiting rods 561 away from the slider 56 are placed in the limiting groove 14. A pulley 562 is rotatably connected between the two limiting rods 561. The pulley 562 is located at the end of the limiting rod 561 away from the slider 56, and the pulley 562 abuts against the side wall of the limiting groove 14. When the slider 56 slides in the slide groove 11, the pulley 562 can slide in the limiting groove 14, thus confining the slider 56 within the slide groove 11.

[0043] Reference Figure 1 , Figure 4 and Figure 5 Two positioning grooves 22 are provided at each of the four corners of the second mounting plate 2. The positioning grooves 22 are located on the side of the second mounting plate 2 closest to the first mounting plate 1, and the diagonal of the second mounting plate 2 is located between the two positioning grooves 22. The opening of the positioning groove 22 is arc-shaped and a spring 221 is provided inside the positioning groove 22. One end of the spring 221 is fixedly connected to the bottom of the positioning groove 22, and the other end of the spring 221 is fixedly connected to a positioning rod 222. The positioning rod 222 abuts against the side wall of the movable solar panel 4 under the action of the spring 221. The movable solar panel 4 is provided with a positioning hole 41 for receiving the positioning rod 222. When the movable solar panel 4 moves to the edge of the first mounting plate 1, the positioning rod 222 can be inserted into the positioning hole 41 on the movable solar panel 4 under the action of the spring 221, thereby fixing the movable solar panel 4 between the first mounting plate 1 and the second mounting plate 2.

[0044] The implementation principle of Example 1 is as follows: when it is necessary to deploy the satellite's solar panels, the drive motor 16 can be started to make the slider 56 move along the slide groove 11 to move the four movable solar panels 4 to a side away from each other. When the slider 56 moves to the end of the slide groove 11 away from the drive gear 13, the positioning rod 222 is inserted into the positioning groove 22 under the action of the spring 221, thereby fixing the position of the movable solar panels 4, thus completing the deployment of the satellite's solar panels. Example 2

[0045] The difference from Example 1 is that: (Refer to...) Figure 6 , Figure 7 and Figure 8A locking groove 111 is formed on the side wall of the slide groove 11 away from the mounting groove 12. A rack 563 is fixedly connected to the side of the slider 56 near the locking groove 111. A threaded rod 6 is provided in the locking groove 111 and is rotatably connected in the locking groove 111. A positioning gear 61 is fixedly connected to the threaded rod 6. The positioning gear 61 meshes with the rack 563 and is axially connected to the threaded rod 6. A threaded cylinder 62 is threadedly connected to the threaded rod 6. The threaded cylinder 62 passes through the side wall of the first mounting plate 1 and is slidably connected to the first mounting plate 1. The threaded cylinder 62 is rectangular. A sliding hole 42 is formed on the movable solar panel 4. The end of the threaded cylinder 62 away from the threaded rod 6 passes through the movable solar panel 4 and is placed in the sliding hole 42. (Refer to...) Figure 9 The second mounting plate 2 has an insertion groove 21 for receiving the threaded cylinder 62 on the side facing the first mounting plate 1. When the slider 56 moves along the slide groove 11 towards the corner of the first mounting plate 1, the rack 563 on the slider 56 meshes with the positioning gear 61. As a result, the positioning gear 61 drives the threaded rod 6 to rotate in the locking groove 111, thereby causing the threaded cylinder 62 to slide along the threaded rod 6 towards the insertion groove 21 in the slide hole 42. Finally, the threaded cylinder 62 is inserted into the insertion groove 21. At the same time, in order to reduce the impact of the slide hole 42 on the light energy receiving area of ​​the moving solar panel 4, the cross section of the slide hole 42 on the side closer to the first mounting plate 1 is larger than the cross section of the slide hole 42 on the side farther away from the first mounting plate 1.

[0046] The implementation principle of Example 2 is as follows: When the movable solar panel 4 is deployed, the threaded cylinder 62 can move gradually into the insertion groove 21 along the threaded rod 6 under the drive of the slider 56. When the slider 56 moves to the corner of the groove 11, the threaded cylinder 62 is inserted into the insertion groove 21, thereby fixing the position of the movable solar panel 4.

[0047] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
