[0023] Example:

[0024] Reference Figures 1-4 This application is a pull-out modular charging cabinet, including a cabinet body 1. A placement opening 2 is provided on one side of the cabinet body 1. A DC output component 3, a module component 6, a control component 7 and an AC input module component 8 are stacked in the cabinet body 1 from top to bottom. The DC output component 3 includes a DC positive output component 4 and a DC negative output component 5. The DC positive output component 4 is located above the DC negative output component 5. DC positive output component 4 and DC negative output component 5 are components with opposite positive and negative poles, both including a DC control contactor, a meter with a shunt, and connecting copper busbars; Module component 6 includes a module support frame and several AC / DC rectifier modules, each standard module component 6 can be freely interchanged within the module support frame; Control component 7 includes a switching power supply, DC / DC power supply, relays, miniature circuit breakers, and other control components; AC input module component 8 includes fuses, molded case circuit breakers, and AC contactors, serving as the AC input power input and output for the charging pile, outputting AC power to each AC / DC module of module component 6. The aforementioned DC positive output component 4, DC negative output component 5, module component 6, control component 7, and AC input module component 8 are all drawer-type structures. Specifically, each component has a frame for installation, allowing each component to be prefabricated externally and then pushed in as a whole, facilitating assembly.

[0025] like Figure 3 and Figure 4As shown, two support bars 14 are vertically arranged inside the cabinet 1 and on opposite sides of the placement opening 2. Several support blocks 15 are arranged between each pair of support bars 14 on the same side. The support blocks 15 on both sides of the placement opening 2 correspond one-to-one and are parallel. The DC output component 3, module component 6, control component 7, and AC input module component 8 are slidably mounted on two opposite support blocks 15. Each of the DC output component 3, module component 6, control component 7, and AC input module component 8 has a mounting plate 16 fixed on the side facing the placement opening 2. Each mounting plate 16 is detachably connected to two opposite support bars 14. By sliding on the two opposite support blocks 15, the above components can be pulled out of the cabinet 1. The mounting plate 16 is limited by its contact with the support bars 14, and the mounting plate 16 is fixed to the support bars 14 by external bolts. Figure 1 and Figure 2 As shown, the DC output component 3, module component 6, control component 7, and AC input module component 8 all have several prefabricated connectors 17 on the side facing the mounting port 10. The design of the prefabricated connectors 17 facilitates the wiring of the entire charging cabinet.

[0026] like Figure 1 As shown, a placement door 9 is hinged to the placement opening 2. An installation opening 10 is provided on one side of the cabinet body 1 opposite to the placement opening 2, and an installation door 11 is hinged to the installation opening 10. A cabinet opening 12 is provided on one side of the cabinet body 1, and a cabinet door 13 is hinged to the cabinet opening 12. The placement door 9, installation door 11, and cabinet door 13 are all connected and rotated via hinges. The three-sided door configuration facilitates subsequent maintenance and component replacement.

[0027] like Figure 1 and Figure 2 As shown, the cabinet 1 has a charging cable hole 18 communicating with the interior of the cabinet 1. A swing arm for hanging the charging cable is rotatably mounted on the top of the cabinet 1. The swing arm includes a fixed rod 20, a connecting rod 21, and a hook 22. One end of the fixed rod 20 is rotatably mounted on the top of the cabinet 1 via a pivot, and the other end extends horizontally outward from the cabinet 1. One end of the connecting rod 21 is horizontally hinged to the end of the fixed rod 20 extending outward from the cabinet 1 via a pivot. The hook 22 is located at the other end of the connecting rod 21. The cabinet door 13 has a storage box 23 for hanging the charging gun head. This arrangement, through the rotation of the fixed rod 20 and connecting rod 21 at the top of the charging station, facilitates the movement and connection of the charging cable extending from the charging cable hole 18, providing good flexibility and making it easier for personnel to retrieve the charging cable. Several cooling fans 24 are provided on the mounting door 11 for heat dissipation.

[0030] The basic stacking principle is that the external power supply line is rectified by the module and connected to the DC output. The wiring is done according to the principle of proximity based on the prefabricated connector 17. The primary current and secondary control circuits of each component are laid out in relatively fixed positions. The complete wiring can complete the secondary wiring of the entire assembly in a few minutes. This not only saves the amount of wires used, but also makes it more convenient for on-site installation and wiring, greatly improving the wiring efficiency and reducing the overall cost of the charging cabinet.
