DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0023] like Figures 1 to 4 As shown, the DC charging pile base described in this embodiment mainly includes a base body, a base front cover plate 30 and a base rear cover plate 40.

[0024] The base body is composed of two long base brackets 10 and two short base brackets 20. Figure 1 、 Figure 3As shown, the two long base brackets 10 are spaced between the two short base brackets 20 and welded to the two short base brackets 20 to form a square hole 50 for cable routing. Each of the long base brackets 10 and the short base bracket 20 is provided with a first mounting hole 60 for securing to the foundation or ground, and a second mounting hole 70 for securing to the charging pile body. In this embodiment, multiple first mounting holes 60 and second mounting holes 70 are provided along the length of each of the long base brackets 10 and the short base bracket 20. The design of multiple first mounting holes 60 allows for flexible installation of expansion bolts based on specific site conditions during installation, adapting to various foundation or ground conditions, such as uneven surfaces or obstacles. Furthermore, the four supporting legs and square notches 80 formed in the base body provide clearance for uneven surfaces, further enhancing installation adaptability. In this embodiment, the long base brackets 10, the short base brackets 20, the front base cover 30, and the rear base cover 40 are all made of metal.

[0025] Both the long base bracket 10 and the short base bracket 20 are provided with square notches 80 for routing cables; the square holes 50 extend vertically, and each of the square notches 80 extends horizontally, connecting the square holes 50 with the outside space. This design allows cables to enter the square holes 50 from multiple directions or extend through the square notches 80, facilitating cable layout and connection, and no longer being restricted by a single entry direction. Furthermore, the base body, enclosed by the two long base brackets 10 and the two short base brackets 20, ensures strength while also increasing the size of the square holes 50, further facilitating subsequent cable threading and maintenance.

[0026] The base front cover 30 is fixed to the same end of the two base short brackets 20 and covers the square notch 80 on the adjacent base long bracket 10; the two opposite sides of the base rear cover 40 are bent to form two side panels 41, the two side panels 41 are perpendicular to the base rear cover 40 and are the same length as the base short bracket 20, the base rear cover 40 is tightly attached to the base long bracket 10 away from the base front cover 30, and is fixed to the base short bracket 20 through the two side panels 41. That is, the base front cover 30 is fixed to the front end of the two base short brackets 20 and covers the square notch 80 on the base short bracket 20 and the adjacent base long bracket 10, playing a protective and aesthetic role. The base rear cover 40 has two side panels 41, which are perpendicular to the main part of the base rear cover 40 and are the same length as the base short bracket 20, forming a closed structure, thereby enhancing the overall stability of the base body.

[0027] During the specific implementation process, first insert the expansion bolt into the selected first mounting hole 60, then secure the base body to the foundation or ground. Next, pass the cable through the square hole 50 or square notch 80 as needed, and secure the charging pile body to the base through the second mounting hole 70. Finally, install the front base cover 30 and the rear base cover 40 to complete the installation of the entire charging pile base. This design is simple and convenient to install, and has high flexibility and adaptability.

[0028] In some embodiments, as Figure 3 As shown, a number of screw holes 21 are provided on the two short brackets 20 of the base, and the front cover plate 30 and the side plates 41 of the base are fixedly connected to the corresponding screw holes 21 by screws. This design makes the installation and removal of the front cover plate 30 and the rear cover plate 40 very simple and quick. For example, at the installation site, the staff only needs to use a screwdriver to screw the screws into the corresponding screw holes 21 to complete the fixation, without the need for welding or other complicated assembly operations, which greatly shortens the installation time. At the same time, this detachable design also facilitates subsequent maintenance and repairs. For example, if a damaged front cover plate 30 of the base needs to be replaced, it can be removed by simply removing the corresponding screws, and then a new front cover plate 30 can be installed without disassembling the entire base, thereby improving maintenance efficiency and reducing maintenance costs.

[0029] In some embodiments, as Figure 2 、 Figure 3 As shown, the short base bracket 20 is formed by bending a rectangular metal plate 22. The four sides of the rectangular metal plate 22 are bent inward to form an L-shaped fold 23. The adjacent L-shaped folds are welded and fixed together. The square notch 80 is a notch extending from the rectangular metal plate 22 to the L-shaped fold located at the bottom side of the rectangular metal plate 22. The structure of the long base bracket 10 is consistent with that of the short base bracket 20. The L-shaped fold 23 structure can effectively improve the bending strength and torsional rigidity of the bracket, which enables the base to withstand greater loads and impacts, ensuring the stability and safety of the charging pile, especially in outdoor environments, and can withstand the influence of wind, rain and external forces. In addition, the L-shaped fold 23 not only improves the strength, but also reduces the weight of the bracket because it fully utilizes the cross-sectional shape of the material, rather than simply relying on increasing the material thickness to increase the strength.

[0030] In some embodiments, as Figure 2As shown, the edge of the notch on the rectangular metal plate 22 is bent to form a flange 24. The design of the flange 24 enhances the structural strength of the base and effectively protects the cable passing through the square notch 80. Specifically, the flange 24 increases the thickness and cross-sectional area at the edge of the notch, thereby improving the bending strength and rigidity of the notch edge and preventing the notch edge from deforming or cracking. In particular, after being impacted by external forces or used for a long time, the shape of the notch can be kept stable to avoid affecting the routing of the cable and the overall structure of the base. At the same time, the flange 24 also acts as a protective layer for the cable. When the cable passes through the square notch 80, the flange 24 can prevent the cable from directly contacting the sharp edge of the metal plate 22, avoiding wear or cuts on the cable, thereby extending the service life of the cable and improving the safety of the charging pile.

[0031] In some embodiments, as Figure 2 、 Figure 3 As shown, a space (not shown) is formed between the front and rear base plates 30, 40, and the rectangular metal plate 22 to accommodate cable connectors or other accessories. This structural design utilizes the space formed between the front and rear base plates 30, 40, and the bend of the rectangular metal plate 22 to safely accommodate accessories such as cable connectors, overload protectors, and circuit breakers, protecting them from external environmental influences such as rain, dust, impact, and unexpected external damage. In addition, this space is also conducive to cable management and maintenance, avoiding cable entanglement and clutter. When maintenance or repair is required, simply open the front and rear base plates 30, 40 to easily access the internal cables and connectors, as well as the square holes 50 and square notches 80, making it convenient to operate and replace components.

[0032] The DC charging pile base provided in this embodiment is fixed by the enclosure of the long and short brackets of the base, and cooperates with the structure of the front and rear sealing plates of the base, so that the cable can enter the square hole from multiple directions, realizing a more flexible wiring method, and the long and short brackets of the base are provided with multiple first mounting holes distributed along the length direction. Some or all of the mounting holes can be selectively used for fixing according to the actual situation on site, adapting to various different foundations or ground environments, significantly improving the flexibility and efficiency of installation, and reducing the difficulty and time cost of installation.
