DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0021] like Figure 1-2 As shown, the satellite solar wing sailboard structure includes a sailboard fixing plate 1, a first solar wing sailboard 2, a second solar wing sailboard 3, and a third solar wing sailboard 4. The sailboard fixing plate 1 is fixedly connected to the side of the satellite by bolts. The first solar wing sailboard 2 is connected to the sailboard fixing plate 1 by a hinge structure. The third motor is installed in the circular hole of the hinge, and the third motor drives the rotating shaft of the hinge to rotate, thereby driving the first solar wing sailboard 2 to rotate around the rotating shaft, so that the entire solar wing sailboard can be rotated to a state parallel or vertical to the satellite. A wiring hole is designed at the hinge structure of the sailboard fixing plate 1 to provide a line installation space for the third motor.
[0022] The first solar wing sailboard 2, the second solar wing sailboard 3, and the third solar wing sailboard 4 are all square plate structures. The bottom surface of the first solar wing sailboard 2 is close to the top surface of the second solar wing sailboard 3, and the bottom surface of the second solar wing sailboard 3 is close to the top surface of the third solar wing sailboard 4.
[0023] like Figure 4 As shown, the first solar wing sailboard 2 extends horizontally outward from a corner of the sailboard fixing plate 1, and a circular hole is provided on the extended protruding corner. Figure 5As shown, the second solar wing sailboard 3 extends horizontally outward near a corner of the first solar wing sailboard 2, and a circular hole is provided at the extended protruding corner. The first rotating shaft 7 is arranged in the two circular holes, and the first rotating shaft 7 is rotatably connected to the first solar wing sailboard 2 and fixedly connected to the second solar wing sailboard 3. The first motor 5 is fixedly connected to the first solar wing sailboard 2, drives the first rotating shaft 7 to rotate, and thus drives the second solar wing sailboard 3 to rotate with the first rotating shaft 7 as the center.
[0024] At the same time, the first solar wing sailboard 2 is also provided with a first guide member 21 on the side away from the sailboard fixing plate 1, and the top surface of the second solar wing sailboard 3 is provided with a first guide groove 31. When the second solar wing sailboard 3 rotates around the first rotating shaft 7, the first guide member 21 moves along the first guide groove 31.
[0025] An embodiment of the first guide member 21 is a roller structure. The cross section of the first guide groove 31 is a T-shaped structure. When the roller rolls in the first guide groove 31 , the roller surface rolls in contact with the upper and lower bottom surfaces of the first guide groove 31 .
[0026] Another embodiment of the first guide member 21 is a rotating shaft structure, which is rotatably connected to the first solar wing sailboard 2. The bottom end of the rotating shaft is a pillow block, and the bottom surface of the pillow block can be set to a spherical shape to reduce friction. The cross-section of the first guide groove 31 is a T-shaped structure. When the rotating shaft moves in the first guide groove 31, it rotates and contacts with the inner side surface of the first guide groove 31.
[0027] like Figure 5 As shown, the second solar wing sailboard 3 extends outward away from the corner of the first solar wing sailboard 2 and is provided with a circular hole, and the third solar wing sailboard 4 extends outward close to the corner of the second solar wing sailboard 3 and is provided with a circular hole. The second rotating shaft 8 is arranged in the two circular holes. The second rotating shaft 8 is fixedly connected to the second solar wing sailboard 3 and is rotationally connected to the third solar wing sailboard 4. The second motor 6 is fixedly connected to the bottom surface of the third solar wing sailboard 4. The second motor 6 drives the second rotating shaft 8 to rotate, thereby driving the third solar wing sailboard 4 to rotate around the axis of the second rotating shaft 8.
[0028] A second guide groove 41 is provided on the top surface of the third solar wing sailboard 4, and a second guide member 32 is provided on the side of the second solar wing sailboard 3 away from the first solar wing sailboard 2. When the third solar wing sailboard 4 rotates around the axis of the second rotating shaft 8, the second guide member 32 moves in the second guide groove 41.
[0029] The structure of the second guide member 32 may be consistent with that of the first guide member 21 , and the structure of the second guide groove 41 may be consistent with that of the first guide groove 31 .
[0030] The initial state of the entire solar wing sailboard is that the solar wing surface is attached to the side surface of the satellite. When the satellite is in operation, the solar wing sailboard works. First, the third motor of the sailboard fixing plate 1 enters the operation state, and the entire solar wing structure is rotated 90° to be perpendicular to the side of the satellite. The third motor in the sailboard fixing plate 1 stops running. At this time, the motor connecting the second solar wing sailboard 2 and the third solar wing sailboard 4 starts to be powered on. The second motor 6 drives the third solar wing sailboard 4 to rotate 90° relative to the second solar wing sailboard 3 and then stops. The first motor 5 drives the second solar wing sailboard 3 to rotate 90° relative to the first solar wing sailboard 2 and then stops. At this time, the entire solar wing has been fully unfolded and entered the working posture.
[0031] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
