[0054] This embodiment provides a satellite, which includes a satellite body and a power controller. The power controller is installed on the satellite body and can convert the electrical energy stored in the solar panels or lithium batteries into different voltage standards to power different payloads and individual units on the satellite body, so as to ensure the normal operation of the satellite body.

[0055] Existing power controllers are typically based on PC104 (i.e., mechanical size 3.6 inches × 3.8 inches) circuit boards, which are stacked and plugged into other individual units to work. However, due to their standardized size, when dealing with cylindrical or hexagonal prism-shaped micro-nano satellites weighing less than 10 kg, the power controller is inconsistent with the shape of the entire satellite, resulting in low space utilization and greatly affecting the internal space layout of the micro-nano satellite.

[0056] To solve the above problems, such as Figures 1-3 As shown, the power controller 100 provided in this embodiment includes a top frame 10, a bottom frame 30, a connector 40, and multiple circuit boards 20. The top frame 10 abuts against the circuit boards 20 located on the upper layer. The top frame 10, circuit boards 20, and bottom frame 30 are arranged in parallel. The connector 40 passes through the top frame 10 and multiple circuit boards 20 and is connected to the bottom frame 30. The projection of the circuit board 20 on the horizontal plane has two oppositely arranged outwardly convex arcs at both ends along the first horizontal direction. The outer contours of the top frame 10 and the bottom frame 30 are the same as those of the circuit board 20.

[0057] The power controller 100 provided in this embodiment sets the two ends of the projection of the circuit board 20 on the horizontal plane along the first horizontal direction as two oppositely arranged outward convex arcs. That is, the two sides of the circuit board 20 along the first direction are outward convex arc surfaces. The outer contours of the top frame 10 and the bottom frame 30 are the same as those of the circuit board 20. The space of the cylindrical satellite can be fully utilized. In the hexagonal prism satellite, the above-mentioned arc surfaces are tangent to the hexagon formed by the hexagonal prism, which also makes good use of the space size. It has the characteristics of small size and high space utilization.

[0058] Optionally, the top frame 10 and / or the bottom frame 30 are made of metal. When the heat dissipation of the circuit board 20 is high, the top frame 10 and the bottom frame 30 are in contact with the circuit board 20 to conduct heat. The positions of different circuit boards 20 can be adjusted according to the function. When the overall heat dissipation is high, the top frame 10 or the bottom frame 30 can be installed between the two circuit boards 20 to improve the heat dissipation effect.

[0059] Optionally, the power controller 100 also includes a partition post 50. A partition post 50 is provided between two adjacent circuit boards 20 and between the circuit board 20 and the bottom frame 30. The partition post 50 is sleeved on the outer periphery of the connector 40. The partition post 50 can ensure that a certain distance is maintained between two adjacent circuit boards 20 and between the circuit board 20 and the bottom frame 30. The height of the partition post 50 can be adaptively selected according to the height of the components on the circuit board 20. By sleeved on the outer periphery of the connector 40, the partition post 50 can be prevented from shifting or falling off.

[0060] like Figures 1-4 As shown, the connector 40 includes a pull rod portion 41 and an abutment portion 42. The pull rod portion 41 extends vertically, and the abutment portion 42 is disposed at one axial end of the pull rod portion 41. The pull rod portion 41 passes through the top frame 10 and multiple circuit boards 20 and is threadedly connected to the bottom frame 30. The abutment portion 42 abuts against the top frame 10. In other embodiments, the pull rod portion 41 passes through the bottom frame 30 and multiple circuit boards 20 and is threadedly connected to the top frame 10, and the abutment portion 42 abuts against the bottom frame 30, resulting in a reliable connection and convenient assembly and disassembly.

[0061] like Figure 5 As shown, the top frame 10 is provided with a recess 11, and the abutment part 42 is provided in the recess 11 to save the space occupied by the power controller 100 in the vertical direction, and the surface is flat and beautiful.

[0062] Optionally, the abutment portion 42 is provided with a slot 421 to facilitate the installation of the connector 40 by an installation tool through the slot 421. Specifically, the installation tool is a flathead screwdriver.

[0063] Optionally, there may be multiple connectors 40, which are arranged at intervals along the circumference of the circuit board 20 to improve the overall support strength of the power controller 100.

[0064] Optionally, the connector 40 is made of titanium alloy, which has the advantages of high strength, light weight and high temperature resistance.

[0065] Optionally, the power controller 100 also includes an inter-board cable 60, which connects adjacent circuit boards 20 to ensure the stable operation of the entire satellite system. It is understood that the inter-board cable 60 is soldered on the same side of different circuit boards 20. Circular holes are made in the circuit boards 20 to allow the cable to cross the boards, and adhesive is applied to the circular holes to fix the inter-board cable 60, eliminating the stress caused by the inter-board cable 60 swinging during testing. When the number of signal points required between two adjacent circuit boards 20 is too large, a standard inter-board connector can also be used to connect the two adjacent circuit boards 20.

[0066] Optionally, the power controller 100 further includes connectors 70 and connecting cables 80. The circuit board 20 is connected to the connectors 70 via the connecting cables 80, and the connectors 70 are used to connect to the satellite body. In this embodiment, there are four connectors 70, with two connectors 70 located on both sides of the top frame 10 along the second horizontal direction, and the other two connectors 70 located on both sides of the bottom frame 30 along the second horizontal direction. The circuit board 20 is provided with a first clearance groove 21, and / or the top frame 10 is provided with a second clearance groove 12, and / or the bottom frame 30 is provided with a third clearance groove 31. Connecting cables 80 are provided in the first clearance groove 21, the second clearance groove 12, and the third clearance groove 31. The first clearance groove 21, the second clearance groove 12, and the third clearance groove 31 achieve the function of avoiding the corresponding connecting cables 80, so as to further save the space occupied by the power controller 100. Of course, in other embodiments, the number of connectors 70 can also be one, two, three, or more, and designers can make adaptive selections according to actual needs.

[0067] In this embodiment, among the two connectors 70 disposed on both sides of the top-level frame 10 along the second horizontal direction, one connector 70 is a structurally fixed connector. The top-level frame 10 has a socket 14, and at least a portion of the structurally fixed connector is located within the socket 14 and fixed to the top-level frame 10 by fasteners. The fasteners are screws, ensuring a secure connection and facilitating easy assembly and disassembly. The other connectors 70 are wire-spinning connectors, allowing for selection of the fixing method of the connector 70 according to the position of different individual units on the satellite body.

[0068] Optionally, the top frame 10 has a first mounting hole 13 on its side, and / or the bottom frame 30 has a second mounting hole 32 on its side. The first mounting hole 13 and the second mounting hole 32 are used to connect to the satellite body, so that the power controller 100 will not interfere with other components when connected to the satellite body. Optionally, the power controller 100 is connected to the satellite body by screws or other fasteners.
