Description

Technical Field

[0001] The present application relates to the technical field of satellites, and in particular to a satellite solar wing folding device. Background Art

[0002] A satellite solar wing is a device used to collect solar energy, typically used to power satellites. It consists of a solar panel, which includes multiple photovoltaic panels and multiple inter-panel hinges that connect the panels in sequence into a foldable structure. The inter-panel hinges use torsion springs, which provide power to the solar panel to move from a folded to an unfolded state.

[0003] In order to ensure that the sailboard is unfolded after reaching space, the solar wing also includes a tensioning and releasing device. The tensioning and releasing device mainly uses ropes to restrain each photovoltaic panel when the sailboard is in a folded state to prevent the sailboard from changing from a folded state to an unfolded state. The solar wing is unfolded after the satellite reaches space.

[0004] During the satellite transportation process, in order to accommodate more satellites, multiple satellites are folded together. The folded satellites are placed up and down, so that the solar panels are in a folded state. After the satellite separates from the rocket, the solar panels are driven to unfold under the action of the torsion spring hinge. However, the solar panels are prone to loosening after unfolding, affecting their stability. Summary of the Invention

[0037] The following is combined with Figure 1-7 This application is described in further detail.

[0038] The satellite solar wing folding device disclosed in this application. Figure 1 and Figure 2 The satellite solar wing folding device includes a mounting plate 1 mounted on the satellite body, a mounting frame 2 is provided on the mounting plate 1, and a sailboard 3 is provided on the mounting frame 2. The mounting frame 2 includes a plurality of rotatably connected mounting parts 4, and there are multiple positions for the sailboard 3, and multiple sailboards 3 and multiple mounting parts 4 are provided in a one-to-one correspondence. A torsion spring hinge is provided at the rotation connection of the mounting part 4, and the torsion spring hinge is used to drive two adjacent mounting parts 4 to rotate in a direction away from each other, that is, to rotate to an unfolded state. At the same time, the mounting part 4 and the mounting plate 1 are rotationally connected by a torsion spring hinge. In the initial state, the mounting part 4 is in a folded state. When the sailboard 3 needs to be unfolded, the restriction on the sailboard 3 is released, and the torsion spring hinge drives the multiple mounting parts 4 to rotate at the same time. While rotating, the mounting part 4 drives the sailboard 3 to rotate, so that the sailboard 3 is unfolded.

[0039] Reference Figure 2 and Figure 3 The mounting portion 4 includes a mounting rod 41 and an auxiliary rod 42. The windsurfing board 3 is mounted on the mounting rod 41. The auxiliary rod 42 is arranged at the edge of the mounting portion 4, that is, the auxiliary rod 42 is arranged near the edge of the windsurfing board 3. The auxiliary rod 42 is arranged in a direction perpendicular to the rotation axis of the mounting portion 4. A rotating sleeve 421 is provided at the end of the auxiliary rod 42. The rotating sleeve 421 is sleeved on the rotation axis of the mounting portion 4, and the rotating sleeve 421 is rotatably arranged outside the mounting portion 4. An abutment plate 5 is provided on one side of the auxiliary rod 42. The abutment plate 5 is slidably arranged on the auxiliary rod 42 along the length direction of the auxiliary rod 42. An intermediate component 7 is provided inside the auxiliary rod 42. A driving component 6 is provided on the mounting plate 1. The driving component 6 is connected to the intermediate component 7. The intermediate component 7 is connected to the abutment plate 5. The intermediate component 7 is used to drive the abutment plate 5 to slide in the direction toward the rotation axis of the mounting portion 4.

[0040] After the sailboard 3 is unfolded, the driving component 6 drives the abutment plate 5 to move through the intermediate component 7, and the abutment plate 5 moves to abut against the side of another auxiliary rod 42. When the abutment plate 5 abuts against the sides of two adjacent abutment plates 5 at the same time, it drives the auxiliary rods 42 to be in the same straight line, driving the sailboard 3 to be fully unfolded. At the same time, the auxiliary rods 42 are restricted by the abutment plate 5 to improve the stability of the sailboard 3 after unfolding.

[0041] Reference Figure 3 and Figure 4 An auxiliary slot (not shown) is defined within the auxiliary rod 42. The intermediate assembly 7 includes a rotating rod 71 and a slider 72. The rotating rod 71 is positioned along the length of the auxiliary rod 42 and rotates within the auxiliary slot. A slide slot 422 is defined on the side of the auxiliary rod 42 proximal to the abutment plate 5. The slide slot 422 communicates with the auxiliary slot. The slider 72 is sleeved onto the exterior of the rotating rod 71 and slides within the slide slot 422 along the length of the rotating rod 71. A threaded portion 711 is provided on the exterior of the rotating rod 71, threadedly engaging the rotating rod 71 and the slider 72. The side of the slider 72 extends through the slide slot 422 to the exterior of the auxiliary rod 42 and connects to the abutment plate 5. To adjust the position of the abutment plate 5, the rotating rod 71 is rotated, which in turn moves the slider 72, thereby adjusting the position of the abutment plate 5.

[0042] Reference Figure 1 and Figure 2 , a plurality of abutment plates 5 and a plurality of auxiliary rods 42 are correspondingly provided. When the windsurfing board 3 is folded, the plurality of auxiliary rods 42 are in a folded state. The abutment plates 5 are provided near the end of the auxiliary rod 42. The plurality of abutment plates 5 and the rotation axes of the plurality of auxiliary rods 42 are correspondingly provided. The abutment plates 5 are provided on the side of the auxiliary rod 42 close to another auxiliary rod 42, which is the side close to another auxiliary rod 42 when the auxiliary rod 42 is folded. The threaded portion 711 on the auxiliary rod 42 and the position of the abutment plates 5 are provided correspondingly. After the plurality of mounting parts 4 are fully unfolded, the plurality of abutment plates 5 are respectively cross-arranged on both sides of the mounting part 4 to support and fix the mounting part 4 as a whole. When the auxiliary rod 42 rotates, the plurality of abutment plates 5 are respectively driven to move at the connection point of the plurality of auxiliary rods 42 until they abut against the side of another auxiliary rod 42, so that the plurality of auxiliary rods 42 are in the same straight line so as to be fixed after the overall unfolding.

[0043] Reference Figure 4 and Figure 5The intermediate assembly 7 comprises multiple groups, each mounted on a plurality of auxiliary rods 42. The rotating sleeves 421 on two auxiliary rods 42 are arranged along the rotation axis of the mounting portion 4. A connecting assembly 8 is located within the rotating sleeves 421, connecting the rotating rods 71 ​​within the two intermediate assemblies 7. The connecting assembly 8 comprises a first connecting rope 81 and a steering member 82. The steering member 82 comprises two sets, one mounted within each rotating sleeve 421. One end of the first connecting rope 81 is wrapped around the rotating rod 71. The other end passes through the rotating sleeve 421 and then through the two sets of steering members 82, one within each auxiliary rod 42, where it is wrapped around the rotating rod 71 within the other auxiliary rod 42. The steering member 82 can be configured as a roller, with the first connecting rope 81 wrapped around the side of the roller. As the rotating rod 71 rotates, the first connecting rope 81 is wound around its side, simultaneously pulling the other rotating rod 71 to rotate, thereby achieving synchronized rotation of the multiple rotating rods 71 ​​within the multiple intermediate assemblies 7.

[0044] Reference Figure 4 and Figure 5 The portion of the first connecting rope 81 between the two rollers is aligned with the rotation axis of the mounting portion 4. A retaining groove 821 is provided on the side of the roller. The retaining groove 821 is circular and located on the outer side of the roller. The first connecting rope 81 is retained within the retaining groove 821. Specifically, the first connecting rope 81 moves through different locations on the inner wall of the retaining groove 821 to drive the roller to rotate. As the rotating sleeve 421 rotates, the retaining groove 821 restricts the position of the first connecting rope 81, preventing it from disengaging from the roller. This keeps the first connecting rope 81 and the rotating rod 71 stationary, minimizing interference with the rotation of the rotating sleeve 421. This allows the rotating rod 71 to rotate via the first connecting rope 81 after the rotating sleeve 421 stops rotating.

[0045] Reference Figure 4 and Figure 5 A correction rod 83 is provided in the auxiliary groove. The correction rod 83 is arranged in a direction perpendicular to the rotating rod 71. The correction rod 83 and the rotating rod 71 are spaced apart. After entering the auxiliary rod 42, the first connecting rope 81 passes through the correction rod 83 and is wrapped around the outside of the rotating rod 71. The provision of the correction rod 83 facilitates the winding of the first connecting rope 81 around the rotating rod 71 and facilitates the rotation of the rotating rod 71 when the first connecting rope 81 and the rotating rod 71 are separated, thereby improving the stability of the connection between the first connecting rope 81 and the rotating rod 71.

[0046] Reference Figure 6A mounting slot 11 is provided on the mounting plate 1. The drive assembly 6 includes a drive member 61 and a second connecting rope 62. The drive member 61 is disposed within the mounting slot 11 and can be configured as a motor. One end of the second connecting rope 62 is wound around the output end of the motor, while the other end extends into the auxiliary rod 42 and is wound around the outside of the rotating rod 71. When the windsurfing board 3 needs to be fixed, the drive member 61 rotates to wrap the second connecting rope 62 around the output end of the motor. The second connecting rope 62 drives the rotating rod 71 to rotate. Simultaneously, under the action of the first connecting rope 81, multiple rotating rods 71 ​​are simultaneously rotated, thereby simultaneously adjusting the positions of multiple abutment plates 5 and fixing the rotating connections of multiple mounting portions 4, thereby improving the stability of the windsurfing board 3.

[0047] Reference Figure 4 and Figure 7 A clearance slot 423 is defined on the auxiliary rod 42 near the abutment plate 5, communicating with the auxiliary slot. Initially, the abutment plate 5 is positioned within the clearance slot 423, with the side of the abutment plate 5 flush with the side of the auxiliary rod 42. When the windsurfing board 3 is fully retracted, the side of the abutment plate 5 abuts the side of the other auxiliary rod 42, allowing the auxiliary rod 42 to rotate to the retracted position and preventing the abutment plate 5 from interfering with the folding of the windsurfing board 3.

[0048] Reference Figure 4 and Figure 7 To facilitate the movement of the abutment plate 5 by the rotating rod 71, the abutment plate 5 can move to the outside of the clearance groove 423 and cooperate with the side of the other auxiliary rod 42. The slider 72 includes a sleeve block 721 and an inner block 722. The sleeve block 721 is provided with a sleeve groove 723 in a direction perpendicular to the abutment plate 5. The inner block 722 is slidably arranged in the sleeve groove 723 in a direction perpendicular to the abutment plate 5. The sleeve block 721 is connected to the rotating rod 71, and the inner block 722 is connected to the abutment plate 5. A sloped surface 424 is provided on the side wall of the clearance groove 423. The sloped surface 424 is arranged on the side of the clearance groove 423 close to the rotation axis of the mounting portion 4. In the initial state, the abutment plate 5 is within the clearance groove 423, while the inner block 722 is within the sleeve block 721. The rotating rod 71 rotates through the sleeve block 721 and the inner block 722, driving the abutment plate 5 to move. When the abutment plate 5 moves to the inclined surface 424, it gradually moves to the outside of the clearance groove 423 under the action of the inclined surface 424. At the same time, the inner block 722 slides within the sleeve block 721, allowing the abutment plate 5 to move to abut the other auxiliary rod 42, placing the entire assembly in a tensioned state. A guide surface 9 is provided on the side of the abutment plate 5 near the other auxiliary rod 42. The guide surface 9 is arranged at an angle. When the abutment plate 5 moves, the guide surface 9 abuts the inclined surface 424, allowing the abutment plate 5 to move through the inclined surface 424 to the outside of the clearance groove 423, thereby improving the fixing efficiency.

[0049] The implementation principle of the present application is as follows: the mounting part 4 drives the sailboard 3 to rotate to unfold under the action of the torsion spring hinge, and then the driving part 61 drives the rotating rod 71 to rotate through the second connecting rope 62, and at the same time drives multiple rotating rods 71 ​​to rotate synchronously through the first connecting rope 81. The rotating rod 71 rotates while driving the slider 72 to move. The movement of the slider 72 drives the abutment plate 5 to move to the outside of the give way groove 423 and then continues to move until the abutment plate 5 moves between the two auxiliary rods 42 and abuts against the sides of the two auxiliary rods 42 at the same time. Under the action of multiple abutment plates 5, the mounting part 4 is unfolded as a whole and supported and fixed, thereby improving the stability of the sailboard 3 after unfolding and reducing the loosening phenomenon after the solar wing is unfolded.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
