The secondary power supply includes a display panel fixedly connected to its front side, a terminal block fixedly connected to its rear side, heat dissipation mechanisms fixedly connected to both sides, protective mechanisms at each of its four corners, and a closed top cover fixedly installed on its top.

[0018] 1. This invention provides a high-efficiency secondary power supply for satellites. Through the cooperation of a heat sink, a conductive groove, an air inlet, a dustproof net, a duct, a heat-absorbing copper sheet, a flow channel, and a flow guiding mechanism, the flow guiding mechanism can drive the hot air in the secondary power supply to circulate in the heat sink. The heat-absorbing copper sheet absorbs the heat and dissipates the absorbed heat into the duct.

Through the cooperation of a buffer baffle, a clamping column, a sliding top plate, spring one, spring two, a connecting slide plate, a limiting slide plate, a connecting groove, a limiting groove, and spring three, when the secondary power supply is impacted or dropped, the buffer baffle is compressed, which in turn pushes the clamping column to compress the sliding top plate against spring one, thus buffering the impact on the secondary power supply. At the same time, the connecting slide plate also compresses spring three, making the buffering effect even better, preventing damage to the secondary power supply, and making the secondary power supply more convenient to use.

[0020] 3. This invention provides a high-efficiency secondary power supply for satellites. Through the cooperation of a closed cover, a rotating pressure plate, a pressure block, a pull rod, a sliding baffle, a spring, and a positioning pin, the closed cover can be disassembled simply by pressing the rotating pressure plate. This causes the rotating pressure plate to rotate, which in turn allows the pull rod to slide the sliding baffle, enabling the positioning pin to slide out of the insertion slot. This removes the restriction on the closed cover, making it easier to open by rotating the pressure plate. This also facilitates maintenance of the secondary power supply in case of a malfunction, making the secondary power supply more convenient to use. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to embodiments:

[0030] Example 1

[0031] like Figure 1-4 As shown, this invention provides a high-efficiency secondary power supply for satellites, comprising a secondary power supply 1. A display panel 2 is fixedly connected to the front of the secondary power supply 1, a terminal block 3 is fixedly connected to the rear of the secondary power supply 1, heat dissipation mechanisms 4 are fixedly connected to both the left and right sides of the secondary power supply 1, protective mechanisms 5 are provided at each of the four corners of the secondary power supply 1, and a closed top cover 6 is fixedly installed on the top of the secondary power supply 1. The heat dissipation mechanism 4 includes a heat dissipation box 41, with two heat dissipation boxes 41 respectively fixedly connected to the left and right sides of the secondary power supply 1. Three conductive grooves 42 are opened on the side of the heat dissipation box 41 closest to the secondary power supply 1. An air inlet duct 43 is fixedly connected to the top of the heat dissipation box 41, and a dustproof net 44 is fixedly connected to the inner surface of the air inlet duct 43 away from the secondary power supply 1. An air guide pipe 45 is fixedly connected to the bottom of the air inlet duct 43. The bottom of the air duct 45 extends into the interior of the heat sink 41. Several heat-absorbing copper plates 46 are fixedly connected to the outer surface of the air duct 45. The outer surface of the heat-absorbing copper plates 46 is fixedly connected to the inner surface of the heat sink 41. Three through-flow grooves 47 are opened inside the heat-absorbing copper plates 46. A flow guiding mechanism 48 is fixedly connected to the middle of the bottom end of the air duct 45. The flow guiding mechanism 48 includes a connecting cylinder 481. The connecting cylinder 481 is fixedly connected to the middle of the bottom end of the air duct 45 and communicates with the air duct 45. A motor 482 is fixedly connected to the side of the connecting cylinder 481 away from the secondary power supply 1. The output shaft of the motor 482 extends into the interior of the connecting cylinder 481 and is fixedly connected to a flow guide fan 483. The end of the flow guide fan 483 near the secondary power supply 1 extends into the interior of the middle through-flow groove 42 and is fixedly connected to a flow guide fan 484.

[0032] In this embodiment, when cooling the secondary power supply 1, starting the motor 482 causes the guide fan 483 to drive the guide fan 484 to rotate, thereby causing the hot air in the secondary power supply 1 to circulate through the guide groove 42 inside the heat dissipation box 41. Through the circulation groove 47, the heat-absorbing copper plate 46 absorbs the heat in the hot air and dissipates the absorbed heat into the air duct 45. At the same time, the rotation of the guide fan 483 allows the outside air to circulate through the air inlet duct 43 in the air duct 45, thereby carrying away the heat dissipated by the heat-absorbing copper plate 46, achieving heat dissipation of the secondary power supply 1. This improves the heat dissipation effect of the secondary power supply 1, avoids the performance degradation of the secondary power supply 1 due to high temperature, and ensures that the conversion efficiency of the secondary power supply 1 is not affected.

[0033] Example 2

[0034] like Figure 5-6As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the protective mechanism 5 includes a buffer baffle 51, which is disposed on the outer surface of the secondary power supply 1. A clamping post 52 is provided on both the upper and lower sides of the inner surface of the buffer baffle 51. A sliding groove is provided at each of the four corners of the interior of the secondary power supply 1. One end of the clamping post 52 away from the buffer baffle 51 extends into the interior of the sliding groove and is fixedly connected to a sliding top plate 53. The outer surface of the sliding top plate 53 is slidably connected to the inner surface of the sliding groove. A spring 54 is fixedly connected to the opposite surfaces of the two sliding top plates 53. A spring 55 is fixedly connected to the end of the sliding top plate 53 away from the clamping post 52. The end of the spring 55 away from the sliding top plate 53 is fixedly connected to the inner wall of the sliding groove. A connecting slide plate 56 is fixedly connected to one end of the clamping column 52 near the buffer baffle 51. Limiting slide plates 57 are fixedly connected to both the left and right sides of the outer surface of the connecting slide plate 56. Connecting grooves 58 are opened on both the upper and lower sides of the inner surface of the buffer baffle 51. The connecting slide plate 56 is slidably connected to the inside of the connecting groove 58. Limiting grooves 59 are opened on both the left and right sides of the inner surface of the connecting groove 58. Limiting slide plates 57 are slidably connected to the inside of the limiting grooves 59. By sliding the limiting slide plates 57 in the limiting grooves 59, the sliding direction of the connecting slide plate 56 can be restricted. Springs 510 are fixedly connected to both the front and rear ends of the connecting slide plate 56. The end of the springs 510 away from the connecting slide plate 56 is fixedly connected to the inner wall of the connecting groove 58.

[0035] In this embodiment, when the secondary power supply 1 is impacted or dropped, the buffer baffle 51 will be compressed, which will push the sliding top plate 53 to slide inside the sliding groove 1 by pressing the column 52. This will compress the spring 1 54 and pull the spring 2 55, thereby buffering the impact on the secondary power supply 1. At the same time, the sliding of the connecting slide plate 56 in the connecting groove 58 will compress the spring 3 510, making the buffering effect of the secondary power supply 1 better, avoiding damage to the secondary power supply 1, and making the secondary power supply 1 more convenient to use.

[0036] Example 3

[0037] like Figure 7As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the closed top cover 6 includes a closed cover plate 61, which is disposed on the top of the secondary power supply 1. Two rotating pressure plates 62 are rotatably connected to the left and right sides of the top of the closed cover plate 61. A pressure block 63 is fixedly connected to the bottom of the rotating pressure plate 62 near the secondary power supply 1. The bottom end of the pressure block 63 extends through to the bottom of the closed cover plate 61, and a pulling rod 64 is movably connected to both the front and rear sides. A sliding joint is movably connected to the end of the two pulling rods 64 away from the pressure block 63. The sliding baffle 65 and the closed cover 61 are provided with sliding grooves on the left and right sides of the bottom. The sliding baffle 65 is slidably connected to the inside of the sliding groove. A spring 66 is fixedly connected to the side of the sliding baffle 65 away from the secondary power supply 1. The end of the spring 66 away from the sliding baffle 65 is fixedly connected to the inner wall of the sliding groove. The top left and right sides of the secondary power supply 1 are provided with insertion grooves. A positioning pin 67 is fixedly connected to the side of the sliding baffle 65 close to the secondary power supply 1. The end of the positioning pin 67 away from the sliding baffle 65 passes through the inside of the insertion groove.

[0038] In this embodiment, when disassembling the closed top cover 6, simply pressing the rotating pressure plate 62 will cause it to rotate, allowing the pressure block 63 to slide downwards. This allows the pull rod 64 to pull the sliding baffle 65 to slide inside the sliding groove and compress the spring 66, thereby allowing the positioning pin 67 to slide out from the insertion groove. This removes the restriction on the closed top cover 6, making it easier to open the closed top cover 6 by rotating the pressure plate 62. This also facilitates the maintenance of the secondary power supply 1 in case of a fault, making the use of the secondary power supply 1 more convenient.

[0039] The working principle of the satellite's high-efficiency secondary power supply will be explained in detail below.

[0040] like Figure 1-7As shown, when the satellite secondary power supply is in use, the rotation of the guide fan 484 drives the hot air in the secondary power supply 1 to circulate inside the heat sink 41, allowing the heat-absorbing copper plate 46 to absorb the heat from the hot air and dissipate it into the air duct 45. The guide fan 483 then carries the heat away, achieving heat dissipation for the secondary power supply 1 and preventing performance degradation due to high temperatures. Furthermore, when the secondary power supply 1 is impacted or dropped, the buffer baffle 51 is compressed, which in turn pushes the column 52 to push the sliding top plate 53 against... Spring 54 compresses and pulls spring 55, thus buffering the impact on the secondary power supply 1 and preventing damage. By pressing the rotating pressure plate 62, the rotating pressure plate 62 can be rotated, which in turn drives the pull rod 64 to pull the sliding baffle 65 to slide, allowing the positioning pin 67 to slide out from the insertion slot. This facilitates opening the closed top cover 6 by rotating the pressure plate 62, making it easier to repair the secondary power supply 1 in case of failure and making the secondary power supply 1 more convenient to use.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
