Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0028] Unless otherwise specified, the fixing methods described in the following embodiments are all known in the prior art, such as opening screw holes and fixing with screws.

[0029] like Figure 1 and Figure 2 As shown, this utility model is a satellite power controller housing structure, including a second frame 20 and a first frame 10 that are connected and fixed to each other in an upper and lower position, a cover plate 30 fixed to the top of the second frame 20, and a base plate 40 fixed to the bottom of the first frame 10, wherein:

[0030] Combination Figure 3As shown, the first frame 10 is a square aluminum alloy frame, with its four corners thickened to form four first platforms 11. Each first platform 11 has screw holes 1 for fixing to the second frame 20 using fasteners, such as screws 2. Four mounting feet 12 extend from the outer sides of the four corners, each mounting foot 12 having through holes 3 for fixing to a satellite mounting surface (not shown). The interior of the first frame 10 has a cross-shaped reinforcing rib 13 to enhance its mechanical strength. Each cross-shaped reinforcing rib 13 has several first bosses 14, each with screw holes 1 for mounting a printed circuit board (PCB) 51. A second platform 15 is located between the center of the cross-shaped reinforcing rib 13 and the inner wall of the first frame 10, combined with… Figure 4 As shown, the second platform 15 divides the first frame 10 into left and right halves. Screw holes 1 are provided on both the upper and lower surfaces of the second platform 15. The screw holes 1 on the upper surface are used to install electronic components 52, while the screw holes 1 on the lower surface are used to fix the base plate 40 via fasteners, such as screws 2. It is easy to understand that through holes are provided on the base plate 40 corresponding to the positions of the screw holes 1. Two U-shaped grooves 16 are provided on one side of the first frame 10. Screw holes 1 are provided on both sides of the U-shaped grooves 16, and the first side plate 17 and the second side plate 18 are fixed thereto via fasteners, such as screws. Figure 5 As shown, the first side plate 17 and the second side plate 18 are used to mount the electrical connector 53.

[0031] like Figure 6 As shown, the second frame 20 is a square aluminum alloy frame adapted to the first frame 10. Its four corners are recessed to form connecting platforms 21. The connecting platforms 21 have through holes 3. They are connected and fixed to the first platform 11 of the first frame 10 by fasteners, such as screws 2, thereby fixing the first frame 10 and the second frame 20 to each other. The interior of the second frame 20 is provided with a Π-shaped reinforcing rib 22 to strengthen the strength of the second frame 20. The Π-shaped reinforcing rib 22 is provided with several second protrusions 23. The upper surface of the second protrusions 23 is provided with screw holes 1. The cover plate 30 is installed by fasteners, such as screws. Several slots 24 are provided on one side of the second frame 20 for installing electrical connectors 53.

[0032] Preferably, the upper surfaces of the four corners of the second frame 20 are provided with screw holes 1, and the cover plate 30 is provided with through holes corresponding to the screw holes 1, for further fixing the cover plate 30 by screws 2.

[0033] Furthermore, such as Figure 3As shown, the first boss 14 is located at the intersection of the cross-shaped reinforcing rib 13 and at the connection point with the inner wall of the first frame 10. The PCB 51 is fixed by screws using screws 1 and screw holes 1 on the first boss 14. Preferably, each of the first platforms 11 also has a lower platform 19 on one side. The lower platform 19 has the same height as the first boss 14 and also has screw holes 1 for further fixing the PCB 51 by fasteners such as screws.

[0034] Furthermore, such as Figure 6 As shown, the second frame 20 has four slots 24 on its side, and the shape of the slots 24 is adapted to the electrical connectors 53. Four electrical connectors 53 are installed using the four slots 24.

[0035] Back Figure 2 The base plate 40 has two parts, corresponding to the left and right halves of the first frame 10 respectively, and is fixed to the bottom surface of the first frame 10 by fasteners, such as screws.

[0036] Preferred, such as Figure 4 As shown, the bottom surface of the second platform 15 and the bottom surface of the square aluminum alloy frame of the first frame 10 are an integral structure, forming a mounting surface together.

[0037] It should be noted that the first frame 10 and the second frame 20 differ in their mounting methods for the PCB 51. The PCB 51 is mounted from top to bottom on the upper surface of the cross-shaped reinforcing rib 13 of the first frame 10, while it is mounted from bottom to top on the lower surface of the second frame 20. Because the PCB 51 is mounted from top to bottom on the upper surface of the cross-shaped reinforcing rib 13 of the first frame 10, a U-shaped groove 16 must be opened on the side of the first frame 10 to accommodate the electrical connector 53. Multiple electrical connectors 50 are mounted on the first side plate 17 and the second side plate 18, and then the first side plate 17 and the second side plate 18 are installed in the U-shaped groove 16 of the first frame 10. The second frame 20 mounts the PCB 51 from bottom to top, so only a slot 24 for the electrical connector 51 needs to be opened on the side.

[0038] The first frame 10 has four first platforms 11 inside which multiple electronic components 51 (such as MOSFETs) are installed. The square aluminum alloy frame of the first frame 10, the four first platforms 11, and the second platform 15 of the mounting surface are integrated into one structure. This allows the heat generated by the simultaneous operation of these electronic components to be transferred to the power controller mounting surface through the aluminum alloy frame in a timely manner, and then transferred from the power controller mounting surface to the satellite mounting surface, thereby reducing the temperature of the electronic components and achieving the purpose of protecting the devices.

[0039] Although the present invention has been described in detail above through specific embodiments, it should be understood that the above description is only a preferred embodiment of the present invention. Those skilled in the art can make appropriate modifications, equivalent substitutions and improvements within the spirit and principles of the present invention, all of which should be included within the protection scope of the present invention.
