Description

Technical Field

[0001] The present invention relates to the technical field of navigation equipment, and more specifically, to a solar wing and navigation equipment. Background Art

[0002] With the development of the aerospace industry, satellites have undertaken more and more tasks and their scale has gradually increased, so the demand for energy has also increased. In order to meet the growing demand for energy from satellites, rigid solar wings have emerged. Rigid solar wings mostly use the structure of aluminum honeycomb sandwich and composite material panels. Due to the high reliability, quite competitive power-to-weight ratio and low cost of rigid solar wings, rigid solar wings have become the most widely used battery wings on satellites. At present, almost all satellite solar wings in my country use rigid solar wing structures, such as the Dongfanghong-3 communication satellite, the Beidou navigation experimental satellite and my country's first lunar exploration satellite "Chang'e-1".

[0003] In recent years, the number of space debris has increased due to the increase in the number of space activities. On January 22, 2013, a Russian satellite collided with a piece of debris and failed. Ecuador's first artificial satellite Pegaso was successfully launched on April 26, 2013, but was hit by Russian rocket debris on May 23 and failed. There are more than 16 satellites that have been publicly reported to have failed or abnormal due to debris impact. Relevant scholars predict that by 2035, 3 to 4 satellites will fail or lose some functions every year due to space debris impact.

[0004] However, current satellite designs mostly separate the satellite's power supply system and protection system. The satellite's power supply relies on the solar panels, while the satellite's protection relies on the installation of protective shields on its high-impact risk areas and vulnerable components. This makes the satellite structure redundant, increasing the structural weight and design cost. Summary of the invention

[0005] The purpose of the present invention is to provide a solar wing and navigation equipment to solve the technical problems in the prior art of large solar wing structure cost and weight and high design cost.

[0006] To achieve the above object, the technical solution adopted by the present invention is a solar wing, comprising:

[0007] Energy supply board;

[0008] A plurality of first protective structures are arranged in an array on the energy supply board, wherein the first protective structure includes a first frame and a second frame protruding from the surface of the energy supply board, a light-transmitting hole is formed between the first frame and the second frame, and the first frame, the second frame and the energy supply board enclose a first protective cavity with a triangular cross-section.

[0009] By adopting the above technical scheme, the first frame and the second frame are formed with light-transmitting holes, and light can pass through the light-transmitting holes directly to the energy supply board to realize the effect of solar energy supply. At the same time, the design of the light-transmitting holes makes the first protective structure hollow, which reduces the weight of the first protective structure and thus reduces the weight of the solar wing. In addition, a first protective cavity with a triangular cross-section is formed between the first frame, the second frame and the energy supply board. The first protective cavity has high mechanical strength. When hit by cosmic debris, the first protective cavity undergoes plastic deformation to absorb the impact energy, thereby effectively protecting the main body of the navigation equipment from damage caused by the impact.

[0010] It needs to be further explained that a connection structure may be provided between two adjacent first protective structures to increase the mechanical strength of the two adjacent first protective structures. Specifically, a reinforcing rod may be provided between the two first protective structures.

[0011] In one embodiment, the first protective structure also includes a third frame protruding from the surface of the energy supply plate, the light-transmitting hole is formed between the second frame and the third frame, the light-transmitting hole is formed between the third frame and the first frame, and the third frame, the first frame, the second frame and the energy supply plate enclose the first protective cavity with a triangular cross-section.

[0012] By adopting the above technical solution, the first protective structure adds a third frame, and forms a first protective cavity with the first frame, the second frame and the energy supply board, further improving the mechanical strength of the first protective cavity. At the same time, the second frame and the third frame form light-transmitting holes, and the third frame and the first frame also form light-transmitting holes, thereby avoiding the first protective structure from blocking sunlight and ensuring the energy supply function of the energy supply board.

[0013] In one embodiment, the first frame, the second frame and the third frame are arranged adjacent to each other, and the end of the first frame away from the energy supply board, the end of the second frame away from the energy supply board and the end of the third frame away from the energy supply board are connected at the same fixed point.

[0014] By adopting the above technical solution, the first protective cavity formed by the first frame, the second frame and the third frame is in the shape of a triangular pyramid, and each surface of the first protective cavity forms a stable triangle, which further improves the stability of the first protective cavity.

[0015] In one embodiment, the first protective structure also includes a fourth frame protruding from the surface of the energy supply plate, the light-transmitting hole is formed between the third frame and the fourth frame, the light-transmitting hole is formed between the fourth frame and the first frame, and the fourth frame, the third frame, the first frame, the second frame and the energy supply plate are surrounded to form the first protective cavity with a triangular cross-section.

[0016] By adopting the above technical solution, the first protective structure adds a fourth frame, and forms a first protective cavity with the first frame, the second frame, the third frame and the energy supply board, further improving the mechanical strength of the first protective cavity. At the same time, the third frame and the fourth frame form light-transmitting holes, and the fourth frame and the first frame also form light-transmitting holes, thereby avoiding the first protective structure from blocking sunlight and ensuring the energy supply function of the energy supply board.

[0017] In one embodiment, the first frame, the second frame, the third frame and the fourth frame are arranged in sequence, and the end of the first frame away from the energy supply board, the end of the second frame away from the energy supply board, the end of the third frame away from the energy supply board and the end of the fourth frame away from the energy supply board are connected at the same fixed point.

[0018] By adopting the above technical solution, the first protective cavity formed by the first frame, the second frame, the third frame and the fourth frame is in the shape of a quadrangular pyramid, and each face of the first protective cavity forms a stable triangle, further improving the stability of the first protective cavity.

[0019] In one embodiment, the solar wing also includes a plurality of second protective structures arranged on the edge of the energy supply plate, the second protective structures include a first protective plate and a second protective plate protruding from the surface of the energy supply plate, the first protective plate, the second protective plate and the energy supply plate together form a second protective cavity with a triangular cross-section.

[0020] By adopting the above technical solution, the edge of the energy supply plate is susceptible to collisions with cosmic debris. At the same time, the edge of the energy supply plate is more susceptible to damage than the middle of the energy supply plate. Therefore, a first protective plate and a second protective plate are added to the edge of the energy supply plate. Since the first protective plate and the second protective plate are in the shape of plates, compared with the first protective structure with a hollow structure, the second protective structure formed by the first protective plate and the second protective plate has higher mechanical strength and stronger anti-collision capability.

[0021] In one embodiment, two adjacent first protective structures are arranged adjacent to each other.

[0022] By adopting the above technical solution, multiple first protective structures are arranged compactly, covering the entire surface of the energy supply board, thereby improving the protective performance.

[0023] It needs to be further explained that the first protective structure and the second protective structure can be integrally formed. Specifically, holes are punched out at corresponding positions on a panel of a planar structure, and then the panel is folded in sequence to form a plurality of first protective structures and second protective structures.

[0024] By adopting the above technical solution, the bonding strength between the multiple first protective structures can be increased, and the strength of the multiple second protective structures can also be increased.

[0025] In one embodiment, the energy supply panel is a foldable panel.

[0026] By adopting the above technical solution, the energy supply board can be folded to form a shape surrounding the main body of the navigation equipment, and the first protective structure and the second protective structure on the energy supply board can be used to protect the main body of the navigation equipment from collision with cosmic debris; in addition, the direction of the energy supply board can be adjusted in time through the folding design to obtain greater light intensity.

[0027] In one embodiment, the energy supply plate is a twistable plate.

[0028] By adopting the above technical solution, the energy supply board can be twisted to form a shape surrounding the main body of the navigation equipment, and the first protective structure and the second protective structure on the energy supply board can be used to protect the main body of the navigation equipment from collision with cosmic debris; in addition, the direction of the energy supply board can be adjusted in time through the twisting design to obtain greater light intensity.

[0029] Another object of the present invention is to provide a navigation device, comprising a navigation device body and the above-mentioned solar wing, wherein the solar wing is connected to the navigation device body.

[0030] Compared with the existing solar wing, the main advantages of this embodiment are:

[0031] 1. Under the same weight conditions, the in-plane Young's modulus of the first protective structure can be more than two orders of magnitude higher than that of lightweight materials such as honeycombs, and its out-of-plane strength can be more than one order of magnitude higher. At the same time, its unique microscopic periodic three-dimensional grid structure system provides a path for the application of finite element structural system to design its optimal configuration;

[0032] 2. Compared with the traditional aluminum honeycomb solar wing, the solar wing in this embodiment combines the energy supply and protection of the satellite, achieves the goal of multi-function while reducing weight, and realizes the combination of material design, structural design and functional design.

[0048] like Figures 1 to 3 As shown, a solar wing 100 provided in an embodiment of the present invention includes:

[0049] Energy supply board 1;

[0050] A plurality of first protective structures 2 are arranged in an array on the energy supply board 1. The first protective structure 2 includes a first frame 21 and a second frame 22 protruding from the surface of the energy supply board 1. A light-transmitting hole 3 is formed between the first frame 21 and the second frame 22. The first frame 21, the second frame 22 and the energy supply board 1 enclose a first protective cavity 4 with a triangular cross-section.

[0051] By adopting the above technical scheme, the first frame 21 and the second frame 22 are formed with a light-transmitting hole 3, and light can pass through the light-transmitting hole 3 directly to the energy supply board 1 to realize the function of solar energy supply. At the same time, the design of the light-transmitting hole 3 makes the first protective structure 2 hollow, which reduces the weight of the first protective structure 2 and further reduces the weight of the solar wing 100; in addition, a first protective cavity 4 with a triangular cross-section is formed between the first frame 21, the second frame 22 and the energy supply board 1, which has high mechanical strength. When hit by cosmic debris, the first protective cavity 4 undergoes plastic deformation to absorb the impact energy, thereby effectively protecting the main body of the navigation equipment from damage caused by the impact.

[0052] It needs to be further explained that a connection structure may be provided between two adjacent first protective structures 2 to increase the mechanical strength of the two adjacent first protective structures 2 . Specifically, a reinforcing rod may be provided between the two first protective structures 2 .

[0054] By adopting the above technical solution, the first protective structure 2 adds a third frame 23, and also forms a first protective cavity 4 with the first frame 21, the second frame 22 and the energy supply board 1, thereby further improving the mechanical strength of the first protective cavity 4. At the same time, the second frame 22 and the third frame 23 form a light-transmitting hole 3, and the third frame 23 and the first frame 21 also form a light-transmitting hole 3, thereby preventing the first protective structure 2 from blocking sunlight and ensuring the energy supply function of the energy supply board 1.

[0055] In one embodiment, the first frame 21, the second frame 22 and the third frame 23 are arranged adjacent to each other, and the end of the first frame 21 away from the energy supply board 1, the end of the second frame 22 away from the energy supply board 1 and the end of the third frame 23 away from the energy supply board 1 are connected at the same fixed point.

[0056] By adopting the above technical solution, the first protective cavity 4 formed by the first frame 21, the second frame 22 and the third frame 23 is in the shape of a triangular pyramid, and each face of the first protective cavity 4 forms a stable triangle, further improving the stability of the first protective cavity 4.

[0057] In one embodiment, the first protective structure 2 also includes a fourth frame 24 protruding from the surface of the energy supply plate 1, a light-transmitting hole 3 is formed between the third frame 23 and the fourth frame 24, a light-transmitting hole 3 is formed between the fourth frame 24 and the first frame 21, and the fourth frame 24, the third frame 23, the first frame 21, the second frame 22 and the energy supply plate 1 enclose a first protective cavity 4 with a triangular cross-section.

[0058] By adopting the above technical solution, the first protective structure 2 adds a fourth frame 24, and also forms a first protective cavity 4 with the first frame 21, the second frame 22, the third frame 23 and the energy supply board 1, thereby further improving the mechanical strength of the first protective cavity 4. At the same time, the third frame 23 and the fourth frame 24 form a light-transmitting hole 3, and the fourth frame 24 and the first frame 21 also form a light-transmitting hole 3, thereby preventing the first protective structure 2 from blocking sunlight and ensuring the energy supply function of the energy supply board 1.

[0059] In one embodiment, the first frame 21, the second frame 22, the third frame 23 and the fourth frame 24 are arranged in sequence, and the end of the first frame 21 away from the energy supply board 1, the end of the second frame 22 away from the energy supply board 1, the end of the third frame 23 away from the energy supply board 1 and the end of the fourth frame 24 away from the energy supply board 1 are connected at the same fixed point.

At the same time, the edge of the energy supply plate 1 is also more susceptible to damage than the middle of the energy supply plate 1. Therefore, a first protective plate 51 and a second protective plate 52 are added to the edge of the energy supply plate 1. Since the first protective plate 51 and the second protective plate 52 are plate-shaped, compared with the first protective structure 2 with a hollow structure, the second protective structure 5 formed by the first protective plate 51 and the second protective plate 52 has higher mechanical strength and stronger anti-collision capability.

[0064] By adopting the above technical solution, multiple first protective structures 2 are arranged compactly, covering the entire surface of the energy supply board 1, thereby improving the protective performance.

[0065] It needs to be further explained that the first protective structure 2 and the second protective structure 5 can be integrally formed. Specifically, holes are punched out at corresponding positions on a panel of a planar structure, and then the panel is folded in sequence to form a plurality of first protective structures 2 and second protective structures 5.

[0072] Specifically, the navigation equipment 200 includes satellites, spacecraft, airplanes, cars, ships, trains, and the like.

[0073] Compared with the existing solar wing 100, the main advantages of this embodiment are:

[0074] 1. Under the same weight conditions, the in-plane Young's modulus of the first protective structure 2 can be more than two orders of magnitude higher than that of lightweight materials such as honeycombs, and its out-of-plane strength can be more than one order of magnitude higher.
