[0033] The present utility model provides a assembled power supply cabinet.

[0034] Refer to Figures 1 to 7 , in an embodiment of the present utility model, an assembled power supply cabinet includes:

[0035] A cabinet body 10, the cabinet body 10 includes a first cabinet wall 11 and a second cabinet wall 12 which are oppositely arranged, a top plate 13 embedded and covering the top of the frame body 10, and a bottom plate 14 installed at the bottom of the frame body 10;

[0036] A quick-disassembly assembly component 20, the first cabinet wall 11, the second cabinet wall 12, the top plate 13 and the bottom plate 14 are detachably connected through the quick-disassembly assembly component 20;

[0037] An installation component 30, which is arranged on the outer surface of the top of the top plate 13, and the installation component 30 is used for installing an output copper row 40;

[0038] A main busbar copper row 50, the main busbar copper row 50 is at least arranged on the side wall of one of the first cabinet wall 11 and the second cabinet wall 12, and the other end is electrically connected to the output copper row 40 through an opening formed on the top plate 13.

[0039] At present, most communication energy storage cabinets are integrally welded. At the same time, the output busbar bundles or copper bars are loose parts, which are assembled separately by the client; the integrally welded cabinet has a high cost for transportation. Usually, the cabinet and the battery PACK are sent to the client separately, and then the client transports the products to the terminal; the transportation cost is relatively high. For the integrally welded cabinet, when a certain component is damaged or the appearance is worn and cannot be replaced, it can only be scrapped as a whole; the packaging cost of the integrally welded cabinet is relatively high. For the loose parts such as the module output copper bar, the busbar copper bar, and the lead-out copper bar, there are many components, and the client needs to assemble them according to the instruction manual, which increases the labor cost for the client; for the company, many accessories need to be classified and packed, increasing the packaging, transportation, and labor costs. Therefore, the present utility model is an improvement based on the above-mentioned prior art.

[0040] The solution of the present utility model describes a design of a power supply cabinet that can be quickly assembled and disassembled. The cabinet body is composed of a first cabinet wall 11, a second cabinet wall 12, a top plate 13 and a bottom plate 14, and these components are connected by a quick-disassembly assembly component 20. The quick-disassembly assembly component 20 enables each part of the cabinet body to be quickly installed and disassembled, facilitating transportation, on-site installation and maintenance. The installation component 30 is located on the outer surface of the top of the top plate 13 and is used to install the output copper busbar 40 for easy electrical connection. Maintenance personnel can fix or remove the installation component 30 through simple steps, thus quickly completing the installation or replacement of the output copper busbar 40. It can be understood that the output copper busbar 40 on the top plate can be more easily insulated, reducing the risk of electric shock. The position of the output copper busbar 40 is relatively high, which can reduce the chance of accidental contact and improve safety. The main busbar copper busbar 50 is provided on at least one side wall of the first cabinet wall 11 and the second cabinet wall 12. It can be understood that it can be provided on the side wall of the first cabinet wall 11 or the second cabinet wall 12, or both the first cabinet wall 11 and the second cabinet wall 12 are provided. The other end is electrically connected to the output copper busbar 40 through an opening on the top plate 13, simplifying the electrical connection process. By installing the main busbar copper busbar 50 on the side wall of the cabinet body instead of occupying the space inside the cabinet, it is easier to access the copper busbar for inspection and maintenance. The opening on the top plate 13 enables maintenance personnel to directly contact the connection point between the output copper busbar 40 and the main busbar copper busbar 50. This design reduces the amount of wire used, reduces the possibility of wiring errors, and improves the installation efficiency. By using the installation component 40 to fix the output copper busbar 40, it is possible to avoid loosening or falling off of the copper busbar assembly caused by vibration or other factors, thereby increasing the safety of the entire system. The stable installation method of this solution reduces electrical faults caused by loosening or vibration of the output copper busbar 40, improving the overall safety of the power supply system. Thus, the assembled power supply cabinet of this solution adopts a modular design. By integrating the module output copper busbar and the main busbar copper busbar 50 on the cabinet body, the installation efficiency can be significantly improved, the maintenance process can be simplified, and the safety of the electrical system can be ensured. This design is very suitable for application scenarios that require rapid deployment, such as mobile power stations, temporary construction sites or emergency response facilities, etc. And each component (such as the top plate, bottom plate and cabinet wall) is connected by a quick-disassembly assembly component 20. This design enables the relevant components to be easily disassembled during installation and when the copper busbar needs to be replaced or maintained, without having to disassemble the entire cabinet.

[0041] Refer to Figures 1 to 7, in the embodiment of the present utility model, the main busbar copper row 50 includes a positive busbar copper row 51, a negative busbar copper row 52, a first connecting member 53 and a second connecting member 54. The cross-sections of the positive busbar copper row 51 and the negative busbar copper row 52 are both in an "L" shape. One end of the positive busbar copper row 51 extends along the height direction of the inner side wall of the first cabinet wall 11, and the other end of the positive busbar copper row 51 is connected to the first connecting member 53. The first connecting member 53 is connected to the output copper row 40 through an opening formed in the top plate 13. One end of the negative busbar copper row 52 extends along the height direction of the inner side wall of the first cabinet wall 11, and the other end of the negative busbar copper row 52 is connected to the second connecting member 54. The second connecting member 54 is connected to the output copper row 40 through an opening formed in the top plate 13.

[0042] By arranging the positive busbar 51 and the negative busbar 52 to extend along the height direction of the first cabinet wall 11, the vertical space can be fully utilized, reducing the occupation of the lateral space inside the cabinet. By using connecting members (the first connecting member 53 and the second connecting member 54) to connect the main busbar 50 and the output busbar 40, the maintenance process is simplified. This design enables maintenance personnel to more easily access the connection points for inspection or replacement. The "L"-shaped cross-section design allows the busbar to extend along the height direction of the cabinet wall, thus reducing the occupation of lateral space and facilitating the optimization of the internal layout of the cabinet. The "L"-shaped cross-section provides better structural stability compared to a planar cross-section. This shape helps resist bending and deformation, ensuring the reliability of the electrical connection. The "L"-shaped cross-section increases the surface area in contact with air, contributing to improved heat dissipation performance. Good heat dissipation helps reduce the problem of local overheating and extends the service life of electrical equipment. Therefore, the "L"-shaped cross-section design not only helps save space and improve structural stability but also can improve heat dissipation performance and reduce electromagnetic interference, making the busbar more stable and reliable. This design enables the positive busbar 51 and the negative busbar 52 to achieve efficient electrical connection within a limited space and is also convenient for installation and maintenance. Optionally, the cross-sections of the first connecting member 53 and the second connecting member 54 can be rectangular or circular, can be fixed by bolts or crimping, or can be U-shaped cross-sections, which can form a tight fit with the busbar, or T-shaped cross-sections, which can better cooperate with the busbar and the output busbar, or I-shaped cross-sections. It can be understood that bolts are used to pass through the holes on the positive busbar 51 and the negative busbar 52, and then the nuts are tightened to fix the busbars. This fixing method requires pre-drilling holes on the cabinet wall and ensuring that the positions of the holes correspond to the holes on the busbars. For a metal cabinet wall, the busbar can be directly welded to the cabinet wall. This is a permanent fixing method, but it should be noted that the heat during welding may affect the surrounding materials, so careful operation is required. It can also be to design special clamps or brackets to fix the busbar. This method can fix the clamp to the cabinet wall with screws, and the clamp holds the busbar to achieve fixation. This method is relatively flexible and convenient for installation and maintenance. It can also be to use insulating supports (such as plastic or ceramic materials) to fix the busbar to the cabinet wall, which can not only ensure the stability of the fixation but also avoid the risk of short circuit.

[0043] Referring to Figures 1 to 7 , in the embodiment of the present utility model, the cross-sections of the first connecting member 53 and the second connecting member 54 are both in an "L" shape.

[0044] The "L"-shaped cross-section design enables the connecting piece to extend along the height direction of the cabinet wall without occupying too much lateral space. This design helps to optimize the space layout inside the cabinet, leaving more space for other electrical equipment. The "L"-shaped cross-section provides better structural stability compared to a planar cross-section. This shape helps to resist bending and deformation, ensuring the reliability of the electrical connection. The "L"-shaped cross-section design enables the connecting piece to be firmly installed on the cabinet wall. Installed in this way, the connecting piece is more accessible, facilitating maintenance and inspection. Through the "L"-shaped cross-section design, the connecting piece can be more easily matched and connected with the positive busbar 51, the negative busbar 52, and the output busbar 40.

[0045] Referring to Figures 1 to 7 In the embodiment of the present utility model, the mounting assembly 30 includes a first annular enclosing plate 31 and a second annular enclosing plate 32. The first annular enclosing plate 31 is disposed at the opening 14, and the second annular enclosing plate 32 is disposed above the first annular enclosing plate 31. A first mounting gap and a second mounting gap are formed between the two side walls of the second annular enclosing plate 32 and the two side walls of the first annular enclosing plate 31. The output busbar 40 is disposed above the second annular enclosing plate 32. The first connecting piece 53 and the second connecting piece 54 extend out from the first mounting gap and the second mounting gap respectively through the opening to be electrically connected to the output busbar 40.

[0046] The first annular enclosing plate 31 is installed at the opening 14 on the top plate 13 to form a closed boundary around the opening. The second annular enclosing plate 32 is installed above the first annular enclosing plate 31, jointly forming a first mounting gap and a second mounting gap with the first annular enclosing plate 31, so that the first connecting piece 53 and the second connecting piece 54 can be conveniently connected to the output busbar 40, facilitating installation and maintenance. The output busbar 40 is installed above the second annular enclosing plate 32 and is located within the area formed by the first annular enclosing plate 31 and the second annular enclosing plate 32, which can significantly improve the installation efficiency and maintenance convenience. At the same time, it optimizes the space layout inside the cabinet and improves the safety of the system. This solution realizes the stable installation of the output busbar 40 by using the mounting assembly 30 composed of the first annular enclosing plate 31 and the second annular enclosing plate 32, and is connected to the main busbar 50 through the first connecting piece 53 and the second connecting piece 54, simplifying the electrical connection process. This design not only improves the installation efficiency and maintenance convenience, but also optimizes the space layout inside the cabinet and improves the safety of the system.

[0047] Referring to Figures 1 to 7 In the embodiment of the present utility model, the annular enclosing plate 31 and / or the second annular enclosing plate 32 are / is polygonally arranged, and the cross-sectional area of the annular enclosing plate 31 is larger than the cross-sectional area of the second annular enclosing plate 32.

[0048] Specifically, the first annular shroud 31 and / or the second annular shroud 32 are arranged in a polygon shape. By adopting a polygon design, the structural stability of the annular shroud 31 and the second annular shroud 32 can be enhanced, thereby improving the reliability of electrical connection. Moreover, by adjusting the angles and side lengths of the polygon, the shapes of the annular shroud 31 and the second annular shroud 32 can be optimized to adapt to different space requirements. The annular shroud 31 and the second annular shroud 32 with a polygon design can provide better structural stability, optimize the space layout, improve safety, facilitate maintenance, and simplify the installation process.

[0049] Referring to Figures 1 to 7 , in the embodiment of the present utility model, the assembled power supply cabinet further includes a frame 60, the cabinet body 10 covers the outer surface of the frame 60, the frame 60 has a first connecting beam 61 extending in the X direction, a second connecting beam 62 extending in the Y direction, and a third connecting beam 63 extending in the Z direction. The quick-disassembly assembly component 20 includes a first mounting member 21, a second mounting member 22, and a third mounting member 23 that are connected to each other. The first mounting member 21 is detachably connected to the first connecting beam 61, the second mounting member 22 is detachably connected to the second connecting beam 62, and the third mounting member 23 is detachably connected to the third connecting beam 63.

[0050] A stable support structure is provided by the connecting beams in the three XYZ directions of the frame 60. The quick-disassembly assembly component 20 is connected to the frame 60 through the first mounting member 21, the second mounting member 22, and the third mounting member 23, which can ensure that the forces on the cabinet in different directions are evenly distributed, improving the overall structural strength. Through the detachable connection method, the cabinet body 10 can be quickly installed or disassembled without tools. The design of adopting the frame 60 and the quick-disassembly assembly component 20 can improve the structural stability, optimize the space layout, simplify the installation process, and improve the installation efficiency. This design not only enhances the overall performance of the cabinet but also improves the safety of the system, making the installation and maintenance simpler and more efficient. Through the cooperation of the connecting beams in the three directions of the frame 60 and the quick-disassembly assembly component 20, the stability and reliability of the cabinet in different directions can be ensured.

[0051] Referring to Figures 1 to 7 , in the embodiment of the present utility model, at least part of the interiors of the first connecting beam 61, the second connecting beam 62, and the third connecting beam 63 are hollow, for the first mounting member 21, the second mounting member 22, and the third mounting member 23 to be inserted correspondingly one by one.

[0052] The design of the slots enables each mounting component to be directly inserted into the slots of the corresponding connecting beams, simplifying the installation process. This design can reduce the installation time and lower the possibility of wiring errors. The cooperation of the first connecting beam 61, the second connecting beam 62, and the third connecting beam 63 with the slot design and the first mounting component 21, the second mounting component 22, and the third mounting component 23 can significantly improve the installation efficiency and maintenance convenience. At the same time, it optimizes the space layout inside the cabinet and enhances the system's safety. This design not only simplifies the electrical connection process but also enhances the overall performance and reliability of the system. Through the cooperation of the slots and the mounting components, the stability and reliability of the cabinet in different directions can be ensured. It can be understood that the extension range of the first mounting component 21, the second mounting component 22, and the third mounting component 23 within the corresponding slots is less than the length inserted into the slots.

[0053] Referring to Figures 1 to 7 , in the embodiment of the present utility model, both the first connecting beam 61 and the first mounting component 21 are provided with a plurality of connecting through holes arranged at intervals, and the first mounting component 21 is detachably mounted on the first connecting beam 61 by means of connecting pins in cooperation with the connecting through holes.

[0054] The cooperation of the connecting pins and the connecting through holes can ensure a firm connection between the mounting component and the connecting beam, improving the safety of electrical connections. This design helps reduce the risk of electrical failures. Moreover, the design of the connecting through holes can reduce the interference between the mounting components, making the installation of other electrical equipment more flexible. This design can better utilize the space inside the cabinet and improve the layout efficiency inside the cabinet. Therefore, the design using connecting pins and connecting through holes can significantly improve the installation efficiency and maintenance convenience. At the same time, it optimizes the space layout inside the cabinet and enhances the system's safety. This design not only simplifies the electrical connection process but also enhances the overall performance and reliability of the system. Through the cooperation of the connecting pins and the connecting through holes, the stability and reliability of the cabinet in different directions can be ensured.

[0055] Referring to Figures 1 to 7 , in the embodiment of the present utility model, the cabinet body 10 further includes a cabinet door 15 and a third cabinet wall 16. The cabinet door 15 and the third cabinet wall 16 are arranged opposite to each other and are both detachably connected to the first cabinet wall 11, the second cabinet wall 12, the top plate 13, and the bottom plate 14 through the quick-release assembly component 20.

[0056] Through the quick-release assembly component 20, the cabinet door 15 and the third cabinet wall 16 can be easily disassembled for maintenance or replacement. At the same time, it can also ensure that the cabinet door 15 and the third cabinet wall 16 are firmly installed on the cabinet, improving the safety of electrical connections. This design helps reduce the risk of electrical failures.

[0057] Referring to Figures 1 to 7, in the embodiment of the present utility model, the assembled power supply cabinet further includes a shielding cover 70, and the shielding cover 70 covers the output copper busbar 40.

[0058] The shielding cover 70 covers the output copper busbar 40, which is used to protect the output copper busbar and reduce electromagnetic interference. The shielding cover 70 can prevent personnel from accidentally contacting the live output copper busbar 40 and improve electrical safety. This design helps to reduce the risk of electric shock. The shielding cover 70 can reduce the influence of the electromagnetic field generated by the output copper busbar 40 on external devices. This design helps to improve the overall performance and reliability of the system. The shielding cover 70 can protect the output copper busbar 40 from the influence of the external environment, such as dust, moisture, etc. The design of using the shielding cover 70 to cover the output copper busbar 40 can significantly improve the safety of the system, reduce electromagnetic interference, and protect the output copper busbar from external factors. This design not only enhances the overall performance and reliability of the system, but also optimizes the space layout inside the cabinet. The material selection of the shielding cover 70, metal materials and composite materials are relatively common choices. It can be understood that in the solution of the present application, the material of the shielding cover 70 is preferably acrylic material.
