Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a battery cabinet and energy storage system. Background Technology

[0002] Battery cabinets are devices specifically designed for storing and managing battery packs, and are widely used in data centers, communication base stations, energy storage systems, and new energy fields. To ensure installation stability, existing technologies typically add connectors to the outside of the cabinet, securing it to both the cabinet and the wall with screws for a robust connection. However, this design has several drawbacks: firstly, the separate connections between the connectors and the cabinet and the wall increase installation complexity and reduce construction efficiency; secondly, the exposed connectors affect the overall aesthetics of the cabinet, especially in scenarios with high requirements for the installation environment. Therefore, there is an urgent need for a battery cabinet fixing solution that simplifies the installation process and improves aesthetics. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a battery cabinet and energy storage system that is easy to install and aesthetically pleasing.

[0004] The technical solution adopted by this utility model to solve its technical problem is to propose a battery cabinet, comprising:

[0005] The cabinet includes a cavity for holding a battery pack and a connecting plate opposite to the mounting base. The connecting plate has a first fixing hole that penetrates itself and communicates with the cavity.

[0006] A fixing structure is located within the receiving cavity and is fixedly connected to or integrally formed with the connecting plate, and the fixing structure has a second fixing hole communicating with the first fixing hole;

[0007] Fasteners can pass through the second fixing hole and the first fixing hole in sequence to fix the battery cabinet to the mounting base.

[0008] In the aforementioned battery cabinet, a flow guiding cavity is formed between the fixing structure and the connecting plate. The flow guiding cavity is located between the first fixing hole and the second fixing hole, and can receive the liquid flowing in from the first fixing hole and prevent the liquid from flowing to the second fixing hole.

[0009] In the aforementioned battery cabinet, the connecting plate is also provided with a through-hole. The drain hole is located below the first fixing hole and communicates with the flow guiding cavity. Liquid in the flow guiding cavity can flow out of the connecting plate through the drain hole.

[0010] In the aforementioned battery cabinet, the fixing structure includes an inclined guide portion, and the guide portion forms an angle greater than 90° with the axis of the drain hole.

[0011] In the aforementioned battery cabinet, the fixing structure includes a barrier portion arranged opposite to the connecting plate, and the second fixing hole is provided on the barrier portion, and the second fixing hole is coaxial with the first fixing hole.

[0012] In the aforementioned battery cabinet, the barrier portion is connected to the flow guide portion, and there is a transition arc surface between the barrier portion and the flow guide portion.

[0013] In the aforementioned battery cabinet, the fixing structure includes a rectangular frame that is perpendicularly connected to the connecting plate and extends toward the receiving cavity. The blocking part and the flow guiding part are connected to the rectangular frame, and the area of ​​the rectangular frame is greater than the sum of the areas of the first fixing hole and the drainage hole 122.

[0014] In the aforementioned battery cabinet, two sets of the first fixing holes and the fixing structure are provided, and they correspond one-to-one. There is a height difference between the two sets of the first fixing holes and the fixing structure and the battery pack.

[0015] The technical solution adopted by this utility model to solve its technical problem is to also provide an energy storage system, including:

[0016] The aforementioned battery cabinet;

[0017] A battery pack, wherein the battery pack is detachably disposed within the receiving cavity;

[0018] Fasteners are detachably connected to the mounting base by passing sequentially through the second fixing hole and the first fixing hole.

[0019] In one of the above-mentioned energy storage systems, the fastener includes a head and a threaded portion connected to each other. The diameter of the head is larger than the diameter of the second fixing hole, and the diameter of the threaded portion is smaller than the diameters of the second fixing hole and the first fixing hole.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] 1. In this utility model, by setting a first fixing hole on the connecting plate, the fixing structure is built into the receiving cavity of the cabinet and fixedly connected to the connecting plate or integrally set. The fixing structure also has a second fixing hole communicating with the first fixing hole, so that fasteners can pass through the second fixing hole and the first fixing hole in sequence to fix the battery cabinet on the mounting base. This design not only simplifies the installation steps of the battery cabinet and improves the fixing efficiency, but also realizes the hidden design of the fixing structure, effectively improving the overall aesthetics of the cabinet. It is especially suitable for scenarios with high requirements for the installation environment.

[0022] 2. In this utility model, by forming a flow guiding cavity between the fixed structure and the connecting plate, and the flow guiding cavity being located between the first fixed hole and the second fixed hole, it can receive the liquid flowing in from the first fixed hole and prevent the liquid from flowing to the second fixed hole, thereby preventing the liquid from further penetrating into the receiving cavity, which significantly improves the waterproof capability of the battery cabinet.

[0023] 3. In this utility model, by making the fixed structure have an inclined guide part and forming an angle greater than 90° between the guide part and the axis of the drain hole, it is ensured that the liquid can flow smoothly along the guide part to the drain hole, effectively reducing the risk of liquid backflow.

[0036] like Figures 1 to 6 As shown, in this embodiment, a battery cabinet includes:

[0037] The cabinet 100 includes a receiving cavity 110 for placing a battery pack 300, and a connecting plate 120 opposite to the mounting base (not shown in the figure). The connecting plate 120 is provided with a first fixing hole 121 that passes through itself and communicates with the receiving cavity 110.

[0038] The fixing structure 200 is located inside the receiving cavity 110 and is fixedly connected to or integrally formed with the connecting plate 120. The fixing structure 200 has a second fixing hole 210 that communicates with the first fixing hole 121.

[0039] Fasteners (not shown in the figure) can pass through the second fixing hole 210 and the first fixing hole 121 in sequence to fix the battery cabinet to the mounting base. This design not only simplifies the installation steps of the battery cabinet and improves the fixing efficiency, but also realizes the concealed design of the fixing structure 200, effectively improving the overall aesthetics of the cabinet, and is especially suitable for scenarios with high requirements for the installation environment.

[0040] Specifically, such as Figures 1 to 5 As shown, in this embodiment, the cabinet 100 is rectangular, formed by multiple side panels, a top panel, and a bottom panel, and forms a closed rectangular receiving cavity 110 for storing and managing the battery pack 300. One side panel, located near and opposite the mounting base, is a connecting plate 120 for fixing to the mounting base, which can be any fixing interface such as a wall or bracket.

[0041] In traditional designs, the cabinet 100 is fixed to the mounting base using an external connector. However, external connectors suffer from low installation efficiency and poor aesthetics. Therefore, in this embodiment, the connecting plate 120 has a first fixing hole 121 that penetrates through itself and communicates with the receiving cavity 110. This hole is used to connect with the mounting base using fasteners, allowing the cabinet 100 to be fixed to the mounting base. This design allows the fasteners to be hidden inside the cabinet 100, improving the aesthetics of the cabinet's exterior and simplifying the fixing process. Preferably, the first fixing hole 121 is an oblong hole, which provides a wider adjustment range, adapts to various installation environments, and reduces the requirements for installation precision.

[0042] However, the single first fixing hole 121 design suffers from low connection strength. To address this, this embodiment also includes a fixing structure 200. This fixing structure 200 is located within the receiving cavity 110 and is fixedly connected to or integrally formed with the connecting plate 120. The fixing structure 200 also has a second fixing hole 210 communicating with the first fixing hole 121. This design, on the one hand, ensures the connection strength between the cabinet 100 and the mounting base through the fixed connection between the fixing structure 200 and the connecting plate 120, reducing installation steps and improving construction efficiency; on the other hand, the concealed design makes the overall appearance of the cabinet more concise and integrated, making it particularly suitable for scenarios with high environmental requirements. It also reduces the risk of aging and damage to external components, extending the service life of the cabinet.

[0043] In practical use, after the fasteners pass through the second fixing hole 210 and the first fixing hole 121 sequentially and are connected to the mounting base, liquids from the external environment (such as rainwater, cleaning water, or condensate) may seep into the receiving cavity 110 along the fasteners through the first fixing hole 121, thereby damaging the battery pack 300 inside the receiving cavity 110. Therefore, in this embodiment, the fixing structure 200 protrudes towards the receiving cavity 110 and forms a guide cavity 220 between it and the connecting plate 120. This guide cavity 220 is located between the first fixing hole 121 and the second fixing hole 210, and can receive the liquid flowing in from the first fixing hole 121 and prevent it from flowing to the second fixing hole 210. Through the design of the guide cavity 220, the liquid flowing in from the first fixing hole 121 can be received and temporarily stored, preventing the liquid from further penetrating into the receiving cavity 110, which significantly improves the waterproof capability of the battery cabinet.

[0044] In this embodiment, the connecting plate 120 is provided with a through-hole 122. This drain hole 122 is located directly below the first fixing hole 121 and communicates with the guide cavity 220. Liquid within the guide cavity 220 can flow out of the connecting plate 120 through the drain hole 122. The layout of the drain hole 122 conforms to the principle of gravity drainage, enabling rapid drainage of liquid from the guide cavity 220, keeping the inside of the cabinet dry, effectively reducing the risk of short circuits or leakage, and improving the safety of equipment operation. Simultaneously, the presence of the drain hole 122 reduces the need for manual cleaning of accumulated liquid, lowering maintenance costs.

[0045] Preferably, in this embodiment, the drain hole 122 is a waist-shaped hole. This design increases the drainage flow rate, ensures smooth liquid outflow, and effectively avoids liquid stagnation.

[0046] In this embodiment, the fixing structure 200 includes an inclined guide section 230, which is inclined toward the receiving cavity 110 and forms an angle greater than 90° with the axis of the drain hole 122. This design creates a natural guiding path, allowing liquid to flow along the guide section 230 to the drain hole 122 instead of flowing back to other areas, significantly reducing the possibility of liquid backflow, and utilizing gravity to accelerate liquid flow and reduce drainage time.

[0047] In this embodiment, the fixing structure 200 further includes a rectangular barrier portion 240 arranged opposite to and parallel to the connecting plate 120. A second fixing hole 210 is provided on the barrier portion 240, and the second fixing hole 210 is coaxial with the first fixing hole 121. The design of the barrier portion 240 enhances the overall rigidity of the fixing structure 200, enabling it to better withstand external loads and avoid deformation or failure caused by vibration or impact. The coaxial design of the first fixing hole 121 and the second fixing hole 210 reduces installation errors, allowing for convenient insertion of fasteners and effectively improving the connection strength and convenience of the fasteners.

[0048] In this embodiment, the barrier portion 240 is disposed above and connected to the guide portion 230, and a transition arc surface 241 is provided between the barrier portion 240 and the guide portion 230. The design of this transition arc surface 241 not only eliminates the stress concentration problem caused by sharp connection and extends the service life of the fixing structure 200, but also allows the liquid to flow smoothly along the transition arc surface 241, reducing stagnation.

[0049] In this embodiment, the fixing structure 200 includes a rectangular frame 250 that is perpendicularly connected to the connecting plate 120 and extends toward the receiving cavity 110. The barrier portion 240 and the guide portion 230 are connected to the rectangular frame 250, and the area of ​​the rectangular frame 250 is greater than the sum of the areas of the first fixing hole 121 and the drain hole 122. The design of the rectangular frame 250 provides a stable connection base for the barrier portion 240 and the guide portion 230, ensuring the stability of the entire fixing structure 200, significantly enhancing the overall rigidity of the fixing structure 200, and improving the load-bearing capacity. At the same time, the area of ​​the rectangular frame 250 ensures that the guide cavity 220 has sufficient space to cover the liquid inflow and outflow paths of the first fixing hole 121, thereby effectively preventing liquid from entering the receiving cavity 110, significantly improving the waterproof capability of the battery cabinet, and protecting the battery pack 300 from the effects of a humid environment.

[0050] Preferably, in this embodiment, the rectangular frame 250 is composed of four connecting edges that are connected end to end in sequence.

[0051] To further enhance the connection strength between the cabinet 100 and the mounting base, in this embodiment, two sets of first fixing holes 121 and fixing structures 200 are provided, each corresponding to one above the connecting plate 120, and there is a height difference between the two sets of first fixing holes 121 and fixing structures 200 and the battery pack 300. This design avoids stress concentration problems that may occur at a single fixing point, extending the service life of the cabinet; on the other hand, it improves the convenience of fastener assembly and avoids interference between the battery pack 300 and the fastener installation.

[0052] In this embodiment, during battery cabinet installation, simply place the cabinet 100 in the designated position, then horizontally insert the fasteners into the second fixing hole 210 and the first fixing hole 121 in sequence, and connect them to the mounting base through the first fixing hole 121 to complete the fixing of the battery cabinet. Compared with the traditional design, this saves the step of connecting the fixing structure 200 to the cabinet 100, and also achieves a concealed design for the fixing structure 200.

[0053] like Figures 1 to 6 As shown, in this embodiment, an energy storage system is also provided, including:

[0054] The aforementioned battery cabinet;

[0055] A battery pack 300, wherein multiple battery packs 300 are provided and are detachably disposed within the receiving cavity 110;

[0056] Fasteners (not shown in the figure) are detachably connected to the mounting base by passing sequentially through the second fixing hole 210 and the first fixing hole 121. This design ensures that the energy storage system can be easily and efficiently fixed to the mounting base, while also improving the overall aesthetics of the energy storage system.

[0057] In this embodiment, the fastener is an expansion screw, which includes an interconnected head and a threaded portion. The diameter of the head is larger than the diameter of the second fixing hole 210, and the diameter of the threaded portion is smaller than the diameters of the second fixing hole 210 and the first fixing hole 121. This design ensures that the fastener will not completely pass through the first fixing hole 121 and the second fixing hole 210, avoiding the risk of the fastener falling off.
