[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] Reference Figure 1 This application discloses a miniaturized portable power supply box with an overall enclosed design to prevent the intrusion of wind and sand. It includes a power supply box body 1 and a connecting panel 2. The power supply box body 1 has an internal cavity that extends to the front end of the power supply box body 1 to form an access port. Power devices are installed inside the cavity. The connecting panel 2 is detachably embedded in the access port on the power supply box body 1 and is flush with the front of the power supply box body 1 after installation. The connecting panel 2 is used to install external connectors and is fixed by bolts. By removing the connecting panel 2, the power devices inside the power supply box body 1 can be inspected and repaired.

[0029] Reference Figures 2-6, in this embodiment, the power supply box body 1 includes an integrally arranged frame body 11, a front mounting plate 12, an upper cover plate 13 and two side support plates 14. Among them, the front end and the upper end of the frame body 11 are both open structures, and the rear end of the frame body 11 is fixedly connected with a fixed baffle 15 to form a closed structure. The front mounting plate 12 is fixedly connected to the maintenance port for the installation of the connection panel 2. The front mounting plate 12 is installed by an embedded design. The two side support plates 14 are respectively fixedly connected to the inner walls of both sides of the frame body 11 by embedded welding. The upper cover plate 13 is bolted to the two side support plates 14 to cover the top of the frame body 11, so that a closed structure is formed at the top of the frame body 11. The side support plate 14 is located at the joint between the frame body 11 and the upper cover plate 13. The side support plate 14 is a strip-shaped part, and the joint between the frame body 11 and the upper cover plate 13 is blocked by the side support plate 14 to reduce the influence of sand and dust entering on the power supply devices. The front mounting plate 12 and the side support plate 14 are embedded and welded on the frame body 11, and the embedded dimensions are respectively the same as the thicknesses of the connection panel 2 and the upper cover plate 13, ensuring that the connection panel 2 and the upper cover plate 13 are flush with the power supply box body 1 after installation, and improving the aesthetics of the power supply box. According to actual application needs, other electrical installation interfaces for power supply components are provided on the side of the assembled power supply box body 1.

[0030] Specifically, the height of the fixed baffle 15 is higher than the overall height of the frame body 11. The fixed baffle 15 is fixedly connected to the rear end of the frame body 11 and is an integrally formed structure. The fixed baffle 15 is formed by sheet metal bending, and the two sides of the fixed baffle 15 are fixedly connected to the frame body 11 by welding. The upper cover plate 13 is formed into a U-shaped structure by sheet metal processing, and its two sides are flush with the frame body 11 after installation, making the integrity of the power supply box better. The top and the top of both sides of the fixed baffle 15 are fitted to the inner wall of the upper cover plate 13. At the same time, the height of the front mounting plate 12 is the same as the height of the fixed baffle 15. The front mounting plate 12 is in a ring structure and its outer peripheral wall is fitted to the inner walls of the frame body 11 and the upper cover plate 13. In this embodiment, the front mounting plate 12 is designed in a "return" shape, and the front mounting plate 12 can be fixedly connected and installed by welding. After the upper cover plate 13 covers the frame body 11, the position of the upper cover plate 13 is limited by the fixed baffle 15 and the front mounting plate 12, making the integrity of the power supply box body 1 better, and the installation position of the upper cover plate 13 is stable and accurate.

[0031] More specifically, the power supply box body 1 also includes a first support plate 16 and a second support plate 17. The first support plate 16 is horizontally fixedly connected to the fixed baffle 15, and the second support plate 17 is horizontally fixedly connected to the front mounting plate 12. The first support plate 16 and the second support plate 17 are arranged opposite to each other, and both the first support plate 16 and the second support plate 17 are in contact with the inner wall of the upper cover plate 13. The first support plate 16 and the fixed baffle 15 are integrally formed, and the second support plate 17 is integrally formed with the front mounting plate 12 through sheet metal bending. Through the support of the first support plate 16 and the second support plate 17 for the upper cover plate 13, the installation stability of the upper cover plate 13 is further improved, and the contact area between the first support plate 16 and the second support plate 17 and the upper cover plate 13 is larger, reducing the amount of sand and dust entering the interior of the power supply box body 1. The lengths of the first support plate 16 and the second support plate 17 are both less than the distance between the inner walls on both sides of the frame body 11 to avoid interference with the installation of the side support plate 14. Threaded holes are provided on the first support plate 16, the second support plate 17, and the side support plate 14. The upper cover plate 13 is fixedly connected to the first support plate 16, the second support plate 17, and the side support plate 14 by bolts, so that maintenance can be carried out from above the frame body 11.

[0032] Furthermore, to ensure accurate installation and fixation of the side support plate 14, positioning plates 18 for installing the side support plate 14 are welded and fixedly connected to the inner walls of both sides of the frame body 11. The top of the side support plate 14 located on the positioning plate 18 is on the same horizontal plane as the top of the fixed baffle 15. To further improve the installation accuracy of the upper cover plate 13, a positioning groove 141 is provided on the side support plate 14, and a positioning element 131 that is compatible with the positioning groove 141 is provided on the inner wall of the upper cover plate 13. When installing the upper cover plate 13, the positioning element 131 is inserted into the positioning groove 141.

[0033] Furthermore, the internal cavity of the power supply box body 1 in this application is a sealed environment to prevent wind and sand from entering the power supply box body 1 and affecting the power supply operation. In actual operation, the heat generated is small, and there is no need to open additional heat dissipation holes. Heat dissipation is achieved through the outer wall of the power supply box body 1. To further improve the overall integrity of the power supply box, the front mounting plate 12 is embedded in the front end of the frame body 11, so that the inspection port has a groove structure. The connecting panel 2 is then embedded in the groove structure, that is, the surface of the connecting panel 2 and the outer surface of the power supply box body 1 form a whole plane. The entire power supply box adopts sheet metal and welding processes, which are simple to manufacture and easy to mass-produce.

[0034] To improve the portability of the power supply box, a portable handle 3 is provided on the top of the power supply box body 1. The handle can be foldable. Foot pads 4 are fixedly connected to the four corners of the bottom of the power supply box body 1 to reduce vibration and wear during placement.
