Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the structure of an energy storage cabinet equipped with an electrical box assembly 30 according to an embodiment of the present invention. Figure 2 This is a front view of the electrical box assembly 30 without the first cover 34 and the second cover 35 provided in this embodiment of the utility model. Figure 3 This is a structural schematic diagram provided by an embodiment of the present invention to illustrate the first connecting hole 323, the second connecting hole 324, and the third connecting hole 361.

[0031] This utility model provides an energy storage device, including multiple battery packs and an energy storage cabinet, wherein the multiple battery packs are housed within the energy storage cabinet. Note that in the appendix... Figures 1-5 The battery pack was not shown in the video.

[0032] Specifically, the energy storage cabinet includes a cabinet body 20 and an electrical box assembly 30. The cabinet body 20 is provided with an electrical compartment 21 for assembling electrical equipment. The electrical box assembly 30 includes an outer shell 32, a partition 33, a first cover 34, and a second cover 35. The outer shell 32 is disposed in the electrical compartment 21, and the inner walls of the outer shell 32 and the electrical compartment 21 are connected. The partition 33 is disposed inside the outer shell 32 to separate the space inside the outer shell 32 to form a high-voltage compartment 321 and a low-voltage compartment 322. At least a portion of the high-voltage compartment 321 extends along a first direction 70, and at least a portion of the low-voltage compartment 322 extends along a second direction 80. The high-voltage compartment 321 and the low-voltage compartment 322 are L-shaped, and the first direction 70 and the second direction 80 are perpendicular to each other. The first cover 34 is disposed on the outer shell 32 to cover the high-voltage compartment 321, and the second cover 35 is disposed on the outer shell 32 to cover the low-voltage compartment 322.

[0033] In practical applications, the separation design of the high-voltage compartment 321 and the low-voltage compartment 322 effectively prevents mutual interference between electrical equipment, ensuring that high-voltage and low-voltage equipment operate independently, thus improving equipment safety and stability. The outer shell 32 is positioned along the first direction 70 and the second direction 80, allowing it to support the cabinet 20 from both directions when connected. This design effectively improves the overall strength of the energy storage cabinet, enabling it to withstand more external stress and internal loads, enhancing its structural stability, and effectively preventing deformation and damage, especially during transportation and use. The L-shaped arrangement of the outer shell 32 improves adaptability to the internal space of the energy storage cabinet. This design allows for more flexible space utilization within the electrical compartment 21, enabling electrical equipment to be rationally arranged according to actual needs, thus optimizing the layout of the electrical equipment. For example, when multiple electrical devices are installed and the remaining space is L-shaped, the housing 32 is embedded in the L-shaped space, so that the housing 32 is adjacent to multiple electrical devices at the same time, and multiple holes for wiring are opened on the housing 32. At this time, the wiring harnesses of multiple electrical devices can be connected to the electrical components inside the housing 32 through the holes for wiring on the housing 32, thereby saving the space in the electrical compartment 21 for additional wiring channels.

[0034] In this embodiment, the second direction 80 is the height direction of the cabinet 20, the first direction 70 is the width direction of the cabinet 20, the high-voltage compartment 321 is disposed above the low-voltage compartment 322, and the electrical box assembly 30 is a component independent of the cabinet 20. The electrical box assembly 30 is connected to the cabinet 20 by bolts. In other embodiments of this application, the electrical box assembly 30 may also be a component integrated with the cabinet 20, or it may be partially integrated with the cabinet 20 and partially independent of the cabinet 20. For example, when at least a portion of the electrical box assembly 30 is integrated with the cabinet 20, the side wall of the cabinet 20 may also be the side wall of the high-voltage compartment 321 and / or the low-voltage compartment 322.

[0035] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The outer shell 32 is connected to the opposite side walls and bottom wall of the electrical compartment 21, and multiple electrical devices in the electrical compartment 21 are respectively installed on the upper and lower sides of the high-voltage compartment 321.

[0036] Furthermore, the high-voltage compartment 321 is located above the low-voltage compartment 322. The outer shell 32 at both ends of the high-voltage compartment 321 is connected to the opposite side walls of the electrical compartment 21, and the outer shell 32 at the end of the low-voltage compartment 322 away from the high-voltage compartment 321 is connected to the bottom wall of the electrical compartment 21.

[0037] In practical applications, the outer shell 32 is connected to the opposite side walls and bottom wall of the electrical compartment 21. This design enhances the overall structural connection between the outer shell 32 and the electrical compartment 21, effectively improving the stability of the cabinet 20. During the use of the energy storage cabinet, external pressure or vibration is evenly transmitted through this connection method, reducing local stress concentration and preventing local deformation or damage to the cabinet 20, thus enhancing the energy storage cabinet's impact resistance during transportation, handling, and use. The connection method between the outer shell 32 and the side walls and bottom wall allows the outer shell 32 to provide support in both the first direction 70 and the second direction 80. Through support from multiple directions, the overall load-bearing capacity of the energy storage cabinet structure is further improved. Especially when subjected to large external loads, it can effectively disperse stress and prevent structural damage to the cabinet 20 caused by excessive local load.

[0038] Optionally, see Figure 2 and Figure 3 The outer casing 32 has a first connecting hole 323 and a second connecting hole 324, which are respectively located on opposite side walls of the high-voltage compartment 321 along a first direction 70. The electrical box assembly 30 has a third connecting hole 361 along a third direction, which is perpendicular to the first direction 70 and the second direction 80. The energy storage cabinet includes a first locking member 40, a second locking member 50, and a third locking member 60. The first locking member 40 passes through the first connecting hole 323, the second locking member 50 passes through the second connecting hole 324, and the third locking member 60 passes through the third connecting hole 361. The outer casing 32 and the cabinet body 20 are connected to the cabinet body 20 through the first locking member 40, the second locking member 50, and the third locking member 60.

[0039] Further, see Figure 2 and Figure 3 The electrical box assembly 30 also includes a connecting plate 36, which is located at the end of the weak current compartment 322 away from the strong current compartment 321. The connecting plate 36 is connected to the outer shell 32 and a third connecting hole 361 is opened in the connecting plate 36. The third locking member 60 connects the outer shell 32 and the cabinet 20 through the connecting plate 36.

[0040] In practical applications, by opening a first connection hole 323 and a second connection hole 324 on opposite side walls of the high-voltage compartment 321 of the outer shell 32, and cooperating with a third connection hole 361 on the connecting plate 36, a three-point locking connection is formed between the outer shell 32, the connecting plate 36, and the cabinet 20. This three-dimensional locking structure ensures a firm connection between the components of the energy storage cabinet, effectively preventing loosening or displacement of connections due to long-term use or external forces, thereby improving the stability and service life of the energy storage cabinet.

[0041] In one embodiment, the high-voltage compartment 321 includes a first compartment 3211, the length of which extends along a first direction 70, and the length of the low-voltage compartment 322 extends along a second direction 80. The first compartment 3211 and the low-voltage compartment 322 are L-shaped.

[0042] In practical applications, the partition 33 and the outer shell 32 are integrally molded, ensuring a tight structural connection between these key components. This eliminates potential gaps and joints in traditional designs, thereby improving overall structural stability. Energy storage cabinets designed in this way are less prone to loosening or misalignment under external pressure or vibration. Furthermore, the reduced number of splicing and connection points between components results in more uniform deformation of the overall structure under external forces, avoiding localized deformation or damage caused by weaker connections in traditional designs. This gives the energy storage cabinet higher compressive strength and impact resistance during transportation and use.

[0043] Furthermore, referring to Figure 5 The high-voltage compartment 321 includes a second compartment 3212 that is connected to the first compartment 3211. The length of the second compartment 3212 extends along the second direction 80. The low-voltage compartment 322 is located at the end of the second compartment 3212 away from the first compartment 3211. The first compartment 3211, the second compartment 3212 and the low-voltage compartment 322 are L-shaped. A partition 33 is located between the second compartment 3212 and the low-voltage compartment 322 to separate the second compartment 3212 and the low-voltage compartment 322.

[0044] In practical applications, by adding a second compartment 3212 within the high-voltage compartment 321 and arranging it in an L-shape with the low-voltage compartment 322, not only is the internal space of the high-voltage compartment 321 effectively expanded, but greater flexibility is also provided for the arrangement of electrical equipment. This structural arrangement allows the energy storage cabinet to accommodate more electrical equipment while maintaining an overall compact structure, thereby improving the space utilization efficiency of the energy storage cabinet.

[0045] In one embodiment, reference is made to Figure 4 and Figure 5The low-voltage compartment 322 includes an adjacent and connected first opening 3221 and a second opening 3222, which are perpendicular to each other. The electrical box assembly 30 includes a second cover 35, which is disposed on the outer shell 32 to cover the low-voltage compartment 322. The second cover 35 includes a first part 351 and a second part 352, which are bent and connected. The first part 351 is connected to the outer shell 32 to cover the first opening 3221, and the second part 352 is connected to the outer shell 32 to cover the second opening 3222. The first part 351, the second part 352, and the partition 33 together form a clearance groove 37.

[0046] In practical applications, the perpendicular arrangement of the first opening 3221 and the second opening 3222 facilitates the installation of electrical hardware components such as air switches in the low-voltage compartment 322 by assembly personnel from different directions. Simultaneously, the first and second components 351 and 352 are connected by bending to the outer shell 32, sealing off all openings and improving the compartment's airtightness. This prevents external environmental interference with the internal equipment and enhances the overall safety of the energy storage cabinet. The combination of the first component 351, the second component 352, and the partition 33 forms a clearance groove 37. This groove design not only effectively provides additional space to accommodate wiring and other equipment but also makes the installation of electrical components more convenient. The presence of the clearance groove 37 better prevents damage or improper installation of electrical equipment during installation due to limited space in the electrical compartment 21.

[0047] In one embodiment, reference is made to Figure 4 and Figure 5 The electrical box assembly 30 includes a circuit breaker 38 and a first cover 34. The first cover 34 is disposed on the outer casing 32 to cover the high-voltage compartment 321. The first cover 34 has a clearance hole 341. The circuit breaker 38 is assembled in the high-voltage compartment 321 and extends through the clearance hole 341. The circuit breaker 38 includes an actuator 381 and a control unit 382. The actuator 381 is electrically connected to a conductor and is used to switch between the disconnected and connected states of the conductor. One end of the control unit 382 extends through the clearance hole 341 and is used to control the operation of the actuator 381.

[0048] In practical applications, by opening a clearance hole 341 in the first cover 34 and assembling the circuit breaker 38 in the high-voltage compartment 321, it is ensured that the circuit breaker 38 can easily pass through the hole, allowing operators to directly operate the control unit 382 from the outside. This design not only facilitates the control and maintenance of electrical equipment but also reduces the risk of misoperation or contact current during operation, thus improving safety.

[0049] In one embodiment, reference is made to Figure 4The electrical box assembly 30 includes a second cover 35, which is disposed on the outer shell 32 to cover the low-voltage compartment 322. The second cover 35 has an operation hole 353. The electrical box assembly 30 includes a guide rail 39 and a socket. The guide rail 39 is disposed in the low-voltage compartment 322. The socket and the guide rail 39 are slidably connected. The socket passes through the operation hole 353.

[0050] In practical applications, an operation hole 353 is provided on the second cover 35, which makes it convenient for operators to connect or disconnect the socket from the outside. This design greatly improves the ease of operation of the energy storage cabinet in daily use. Especially when plugging and unplugging is required, it can be operated without opening the cabinet 20 or disassembling other parts, reducing maintenance costs and time.

[0051] In this embodiment, the guide rail 39 can not only slide to connect the socket, but also slide to connect electrical hardware components such as air switches. The projections of the guide rail 39 and the socket on the plane where the operation hole 353 is located partially coincide with the operation hole 353.

[0052] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0053] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0054] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
