Description

Technical Field

[0001] This application relates to the technical field of energy storage cabinets, specifically to an energy storage cabinet. Background Technology

[0002] With the widespread application of renewable energy sources such as solar and wind power, energy storage cabinets are indispensable supporting facilities. They can store intermittent electrical energy generated by renewable energy sources, enabling these energy sources to be more stably integrated into the power grid or directly power local loads, thereby improving the self-consumption rate and utilization rate of renewable energy.

[0003] In existing technologies, energy storage cabinets include a cabinet body and multiple cabinet doors. The cabinet body contains multiple energy storage cavities arranged horizontally, and the multiple cabinet doors are connected to the cabinet body to close or open the corresponding energy storage cavities. However, in existing systems, each cabinet door uses an independent connection method, meaning that each cabinet door has an independent connection structure, which occupies a certain amount of internal space, resulting in low utilization of the internal space. Utility Model Content

[0004] This application provides an energy storage cabinet that can solve the problem of low space utilization caused by multiple cabinet doors using independent connection methods in existing energy storage cabinets.

[0005] To achieve the above objectives, the energy storage cabinet provided in this application includes:

[0006] The cabinet includes at least two energy storage compartments arranged along a first direction, and a column disposed between two adjacent energy storage compartments, with a locking groove recessed on the column.

[0007] The first cabinet door and the second cabinet door are respectively located opposite the two adjacent energy storage compartments, and both are connected to the same column.

[0008] The first connecting side of the first cabinet door is connected to the column, and the second opening and closing side of the second cabinet door is provided with a locking tongue. When the second cabinet door is locked to the cabinet body, the locking tongue on the second opening and closing side is embedded in the locking groove.

[0009] In some embodiments of this application, the column includes a first column portion and a second column portion connected together, the second column portion being located on the side of the first column portion facing the energy storage compartment;

[0011] In some embodiments of this application, the first column portion has an installation space, and the end of the first column portion facing away from the second column portion is provided with a clearance opening. The energy storage cabinet further includes:

[0012] The first connector is located within the installation space and extends at least partially through the clearance opening into the installation space. The first connector is used to connect the first column portion to the first connecting side of the first cabinet door.

[0013] In some embodiments of this application, a first sealing structure is disposed between the first column portion and the first cabinet door, and / or, the first sealing structure is disposed between the second column portion and the first cabinet door.

[0014] In some embodiments of this application, the first sealing structure includes a first sealing element, which is disposed between the first column portion and the first cabinet door;

[0015] The first column portion has a first snap-fit ​​plate, and the first sealing element has a first snap-fit ​​groove, with at least a portion of the first snap-fit ​​plate snapping into the first snap-fit ​​groove.

[0016] In some embodiments of this application, the first sealing structure includes a second sealing element disposed between the second column portion and the first cabinet door;

[0017] The outer side of the second column is connected to the first mounting plate, and the second sealing element is provided with a second snap-fit ​​groove. The end of the first mounting plate near the first cabinet door is snapped into the second snap-fit ​​groove.

[0018] In some embodiments of this application, the energy storage cabinet further includes:

[0019] A second sealing structure is disposed between the first column portion and the second cabinet door, and / or, the second sealing structure is disposed between the second column portion and the second cabinet door.

[0020] In some embodiments of this application, the cabinet has a second direction, which intersects with the first direction;

[0021] The second sealing structure includes a third sealing element and a fourth sealing element, both of which are located between the first column portion and the second cabinet door, and are completely offset in the second direction.

[0022] In some embodiments of this application, the first column portion has a second snap-fit ​​plate, and the third seal is provided with a third snap-fit ​​groove, with at least a portion of the second snap-fit ​​plate snapped into the third snap-fit ​​groove.

[0023] In some embodiments of this application, a protruding post is provided on the side of the second cabinet door facing the energy storage compartment, and a fourth sealing member is connected to the protruding post. When the second cabinet door is locked to the cabinet body, the fourth sealing member is in close contact with the first post.

[0024] The above-mentioned technical solution of this application has at least the following beneficial effects:

[0025] The locking groove is recessed into the column, and the locking tongue only needs to be inserted into the locking groove to achieve the locking function. In other words, the column is recessed inward to form the locking groove, and the design of the locking groove does not occupy any other space outside the column. At the same time, the relevant structures for the locking engagement between the locking tongue and the column are also housed within the locking groove, which does not occupy any other space outside the column. This helps to save space in the energy storage compartment inside the cabinet, improves the space utilization of the energy storage compartment, and allows the space inside the cabinet to be used more effectively for storing energy storage equipment and other structures.

[0049] This application provides an energy storage cabinet, which will be described in detail below with reference to the accompanying drawings. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0050] An energy storage cabinet is a device cabinet used to store energy. With the widespread application of renewable energy sources such as solar and wind power, energy storage cabinets are indispensable as supporting facilities. They can store intermittent electrical energy generated by renewable energy sources, enabling these energy sources to be more stably integrated into the power grid or directly power local loads, thereby improving the self-consumption rate and utilization rate of renewable energy.

[0051] The structural design of an energy storage cabinet must prevent external objects from impacting and damaging internal components (such as battery modules, management systems, and electrical connections). Furthermore, in special environments (such as outdoor energy storage cabinets), it also needs to be dustproof, waterproof, and corrosion-resistant. The cabinet is typically made of metal materials (such as steel) to provide stable structural support for the entire energy storage cabinet.

[0052] In the following detailed description of the energy storage cabinet structure, it is assumed that cabinet 1 has a first direction X, a second direction Y, and a third direction Z that intersect each other.

[0053] This application discloses an energy storage cabinet including a cabinet body 1. The cabinet body 1 includes at least two energy storage compartments 11 arranged along a first direction X, and a column 12 disposed between two adjacent energy storage compartments 11. The column 12 is recessed with a locking groove 121. A first cabinet door 2 and a second cabinet door 3 are respectively disposed opposite to the two adjacent energy storage compartments 11 and are both connected to the same column 12. The first connecting side 21 of the first cabinet door 2 is connected to the column 12, and the second opening and closing side 31 of the second cabinet door 3 is provided with a locking tongue 4. When the second cabinet door 3 is locked to the cabinet body 1, the locking tongue 4 of the second opening and closing side 31 is embedded in the locking groove 121.

[0054] Please combine Figures 1-4 The energy storage cabinet provided in this application includes a cabinet body 1, a first cabinet door 2, and a second cabinet door 3. The cabinet body 1 includes at least two energy storage compartments 11 arranged along a first direction X (the horizontal direction shown in the figure, i.e., the length direction of the cabinet body 1), and a column 12 disposed between two adjacent energy storage compartments 11. The column 12 extends along a third direction Z (the vertical direction shown in the figure, i.e., the height direction of the cabinet body 1), and a locking groove 121 (see reference numerals) is provided on the column 12. Figure 4 The first cabinet door 2 and the second cabinet door 3 are respectively positioned opposite to the two adjacent energy storage compartments 11 and are both connected to the same column 12. Specifically, the first connecting side 21 of the first cabinet door 2 is connected to the column 12, and the second opening and closing side 31 of the second cabinet door 3 is connected to a locking tongue 4. When the second cabinet door 3 is locked to the cabinet body 1, the locking tongue 4 of the second opening and closing side 31 is embedded in the locking groove 121.

[0055] In this embodiment, the locking groove 121 is recessed into the column 12, and the locking tongue 4 only needs to be embedded in the locking groove 121 to achieve the locking function. That is to say, the column 12 is recessed into itself to form the locking groove 121, and the design of the locking groove 121 does not occupy any other space outside the column 12. At the same time, the relevant structure for the locking engagement between the locking tongue 4 and the column 12 is also accommodated in the locking groove 121, which does not occupy any other space outside the column 12. This helps to save space in the energy storage compartment 11 inside the cabinet 1, improves the space utilization rate of the energy storage compartment 11 inside the cabinet 1, and allows the space inside the cabinet 1 to be used more effectively for storing energy storage devices and other structures.

[0056] Furthermore, this application simultaneously assembles adjacent cabinet doors (e.g., the first cabinet door 2 and the second cabinet door 3) onto the same upright 12, avoiding the need for separate connection structures or support components for each cabinet door and improving the space utilization within the cabinet 1. For example, if each cabinet door uses an independent connection method, additional frames, hinges, or other connectors may be required, which would occupy space within the cabinet 1, affecting the layout and installation of the energy storage equipment. Sharing the upright 12 saves space within the cabinet, providing more usable space for the energy storage equipment.

[0057] Please refer to Figure 5 and Figure 6 The column 12 has a locking groove 121 with a locking element 1211. When the second cabinet door 3 is locked to the cabinet body 1, the locking element 1211 connects to the latch 4. The connection between the locking element 1211 and the latch 4 provides an additional locking point. In the event of external impact (such as a collision, vibration, or an attempt to illegally open the cabinet door), the double locking can more effectively prevent the cabinet door from opening accidentally, greatly improving the reliability of the cabinet door locking. Specifically, the locking element 1211 can adopt various connection methods such as snap-fit, hook, or threaded connection to ensure that the cabinet door remains stable in the closed state and avoids accidental opening due to accidental collision or operational errors. For example, the connection between the locking element 1211 and the latch 4 can only be released by a specific unlocking method (such as using a key or special tool), thereby improving the security of the cabinet body 1.

[0058] Specifically, a door lock includes a lock cylinder, a transmission mechanism, and a bolt 4. The lock cylinder and the bolt 4 are usually connected by a specific transmission mechanism. For example, when the lock cylinder rotates, the bolt 4 rotates synchronously with the lock cylinder under the drive of the transmission mechanism, thereby unlocking or locking the bolt 4.

[0059] Please continue to refer to Figure 4 The column 12 includes a first column portion 122 and a second column portion 123 connected together. The second column portion 123 is located on the side of the first column portion 122 facing the energy storage compartment 11. A locking groove 121 is provided on the second column portion 123. The first column portion 122 is connected to the first connecting side 21. In this embodiment, the second column portion 123 is located closer to the energy storage compartment 11 than the first column portion 122. That is, the first column portion 122 is relatively closer to the outer side of the cabinet 1, and the second column portion 123 is relatively closer to the inner side of the cabinet 1. The first column portion 122 is used to connect with the first cabinet door 2, and the second column portion 123 is provided with a locking groove 121 for locking with the second cabinet door 3. The first column part 122 mainly bears the force related to the first cabinet door 2, while the second column part 123 mainly bears the force related to the locking of the second cabinet door 3. This avoids the external force on the cabinet door being concentrated on a single column, thereby improving the overall mechanical stability of the column 12 and enhancing the structural strength of the column 12.

[0060] In some embodiments, the first column portion 122 and the second column portion 123 may be two independent columns.

[0061] When the locking groove 121 is worn or damaged, because it is relatively independent from the first column part 122, maintenance personnel can more easily inspect or replace the second column part 123 and its locking groove 121 without causing too much interference to the connection structure between the first column part 122 and the first cabinet door 2. Similarly, when the connection between the second column part 123 and the second cabinet door 3 is faulty or damaged, the second column part 123 and the second cabinet door 3 can be handled separately, making maintenance and replacement easier.

[0062] Please refer to Figure 4 and Figure 7 The first column portion 122 has an installation space 1221, and a clearance opening 1222 is provided at the end of the first column portion 122 facing away from the second column portion 123. The energy storage cabinet also includes a first connector 5, which is located within the installation space 1221 and extends at least partially through the clearance opening 1222. The first connector 5 is used to connect the first column portion 122 to the first connecting side 21 of the first cabinet door 2. The fact that the first connector 5 is located within the installation space 1221 of the first column portion 122 provides a relatively independent space for it, effectively utilizing the internal space of the first column portion 122 and preventing the first connector 5 from being directly exposed to the outside and occupying additional space. Since most of the first connector 5 is located within the installation space 1221, with only a portion extending through the clearance opening 1222, it effectively prevents the first connector 5 from being directly affected by external factors such as dust, moisture, and accidental collisions.

[0063] For example, the first connecting member 5 can be a hinge, spring hinge, or long-row hinge, etc., resulting in a hinged connection. Alternatively, the first connecting member 5 can be a door hinge. For instance, when the first connecting member 5 is a hinge, the hinge consists of two leaf blades and a pivot pin. One leaf blade is fixed to the cabinet body 1, and the other leaf blade is fixed to the cabinet door. The two leaf blades are connected by the pivot pin, allowing the cabinet door to rotate around the pivot pin, thereby opening and closing the cabinet door.

[0064] Of course, in other embodiments, the energy storage cabinet may also include a second connector for connecting the first column portion 122 of one of the columns 12 adjacent to the aforementioned column 12 to the second connecting side 33 of the second cabinet door 3. The first opening / closing side 22 of the first cabinet door 2 is locked to the second column portion 123 of the other column 12 adjacent to the aforementioned column 12.

[0065] To achieve the sealing function of the energy storage cabinet, the energy storage cabinet also includes a first sealing structure 6. The first sealing structure 6 is disposed between the first column portion 122 and the first cabinet door 2 to achieve a sealed connection between the first column portion 122 and the first cabinet door 2, and / or, the first sealing structure 6 is disposed between the second column portion 123 and the first cabinet door 2 to achieve a sealed connection between the second column portion 123 and the first cabinet door 2.

[0066] Specifically, the first sealing structure 6 can be used to seal the connection between the first column portion 122 and the first cabinet door 2; or, the first sealing structure 6 can also be used to seal the connection between the second column portion 123 and the first cabinet door 2; or, the first sealing structure 6 can also be used to simultaneously seal the connection between the first column portion 122 and the first cabinet door 2, and seal the connection between the second column portion 123 and the first cabinet door 2.

[0067] When the first sealing structure 6 seals the connection between the first column portion 122 and the first cabinet door 2 and / or the second column portion 123 and the first cabinet door 2, the first sealing structure 6 can effectively prevent dust or moisture from entering the cabinet 1 through the gap between the first cabinet door 2 and the column (first column portion 122 and / or second column portion 123), which may affect the normal operation of the equipment inside the cabinet 1, such as accumulating on electronic components, affecting heat dissipation, causing short circuits, etc., thus ensuring the safety and stability of the equipment inside the cabinet 1.

[0068] When the first sealing structure 6 is disposed between the first column portion 122 and the first cabinet door 2, and between the second column portion 123 and the first cabinet door 2, the first sealing structure 6 simultaneously includes a first sealing element 61 and a second sealing element 62. The first sealing element 61 is disposed on the first column portion 122 to seal the connection between the first column portion 122 and the first cabinet door 2. The second sealing element 62 is disposed on the second column portion 123 to seal the connection between the second column portion 123 and the first cabinet door 2. In other words, the first sealing element 61 and the second sealing element 62 are respectively located on the first column portion 122 and the second column portion 123, providing a double seal between the first cabinet door 2 and the column 12. That is, through multiple sealing barriers, the IP66 protection level is ultimately achieved. Compared with a single sealing structure, this double sealing structure can more effectively prevent external substances (such as dust, moisture, etc.) from entering the interior of the cabinet 1. For example, in some places with high environmental requirements, such as energy storage cabinets and computer rooms, even if there is a tiny gap in one seal, the other seal can still play a protective role, greatly improving the sealing performance of cabinet 1.

[0069] When the seals need to be replaced, since the first seal 61 and the second seal 62 are installed separately, maintenance personnel can quickly locate the fault and perform targeted repairs or replacements. For example, the first seal 61 and the second seal 62 can be operated independently without disassembling the entire cabinet door or other complex components, saving maintenance time and costs.

[0070] like Figure 7 As shown, the first sealing structure 6 includes a first sealing element 61, which is disposed between the first column portion 122 and the first cabinet door 2. The first column portion 122 has a first snap-fit ​​plate 1223, and the first sealing element 61 has a first snap-fit ​​groove 611. At least a portion of the first snap-fit ​​plate 1223 snaps into the first snap-fit ​​groove 611. During installation, simply align the first snap-fit ​​groove 611 of the first sealing element 61 with the edge of the first snap-fit ​​plate 1223, and then press the first sealing element 61 to complete the connection. Compared to traditional adhesive methods, this significantly shortens installation time and improves installation efficiency. The snap-fit ​​structure uses the shape fit and friction between the first snap-fit ​​plate 1223 and the first snap-fit ​​groove 611 to firmly fix the first sealing element 61 to the first column portion 122. During normal use of the cabinet 1, even if subjected to certain external impacts or vibrations, the connection between the first sealing element 61 and the first column part 122 will not easily loosen or fall off, thus ensuring the sealing performance of the cabinet door.

[0071] Furthermore, if it is necessary to inspect, repair or replace the first seal 61, simply apply a certain external force to disengage the first snap plate 1223 from the first snap groove 611, and the first seal 61 can be removed. The snap connection structure facilitates the disassembly of the first seal 61 and allows for quick replacement of the new first seal 61.

[0072] For example, the first column portion 122 is generally U-shaped, having a first base plate and two side plates connected to both ends of the first base plate in a first direction X. The two side plates and the first base plate, when connected, enclose an installation space 1221. Each side plate has a flange at its end facing away from the first base plate, and the two flanges extend towards each other. One of the flanges forms a first snap-fit ​​plate 1223. The end of the first base plate facing away from the side plates is connected to the second column portion 123. A gap exists between the free ends of the two flanges, forming a clearance opening 1222. The cross-sectional shape of the second column portion 123, in the portion without the locking groove 121, is approximately the same as the cross-sectional shape of the first column portion 122.

[0073] In this embodiment, the first sealing structure 6 includes a second sealing element 62, which is disposed between the second column portion 123 and the first cabinet door 2. A first mounting plate 124 is connected to the outer side of the second column portion 123. The second sealing element 62 has a second snap-fit ​​groove 621, and the end of the first mounting plate 124 near the first cabinet door 2 snaps into the second snap-fit ​​groove 621. That is, in this embodiment, the second sealing element 62 and the first mounting plate 124 are snap-fit ​​connected, which is the same as the connection method between the first sealing element 61 and the first snap-fit ​​plate 1223 in the above-mentioned technical solutions, achieving the same technical effect, and will not be elaborated further here.

[0074] For example, the first mounting plate 124 includes a first plate portion 1241 and a second plate portion 1242 connected together. The first plate portion 1241 and the second plate portion 1242 are generally L-shaped after being connected and are an integral structure. The first plate portion 1241 is connected to the second column portion 123, and the portion of the second plate portion 1242 facing away from the first plate portion 1241 is engaged in the second engaging groove 621.

[0075] In some embodiments of this application, the energy storage cabinet further includes a second sealing structure 7, which is disposed between the first column portion 122 and the second cabinet door 3 to achieve a sealed connection between the first column portion 122 and the second cabinet door 3, and / or, the second sealing structure 7 is disposed between the second column portion 123 and the second cabinet door 3 to achieve a sealed connection between the second column portion 123 and the second cabinet door 3. Specifically, the second sealing structure 7 can be used to seal the connection between the first column portion 122 and the second cabinet door 3. Alternatively, the second sealing structure 7 can also be used to seal the connection between the second column portion 123 and the second cabinet door 3. Or, the second sealing structure 7 can also be used to seal the connection between the first column portion 122 and the second cabinet door 3, and to seal the connection between the second column portion 123 and the second cabinet door 3.

[0076] When the second sealing structure 7 seals the connection between the first column portion 122 and the second cabinet door 3 and / or the second column portion 123 and the second cabinet door 3, the second sealing structure 7 can effectively prevent dust or moisture from entering the cabinet 1 through the gap between the second cabinet door 3 and the column (first column portion 122 and / or second column portion 123), which may affect the normal operation of the equipment inside the cabinet 1, such as accumulating on electronic components, affecting heat dissipation, causing short circuits, etc., thus ensuring the safety and stability of the equipment inside the cabinet 1.

[0077] Please continue to refer to Figure 4When the second sealing structure 7 seals the connection between the first column portion 122 and the second cabinet door 3, the second sealing structure 7 includes a third sealing element 71 and a fourth sealing element 72. Both the third sealing element 71 and the fourth sealing element 72 are disposed between the first column portion 122 and the second cabinet door 3, and are completely offset in the second direction Y (the thickness direction of the cabinet body 1 shown in the figure, also referring to the thickness direction of the cabinet door). Specifically, the third sealing element 71 is disposed on the first column portion 122 to seal the connection between the first column portion 122 and the second cabinet door 3. The fourth sealing element 72 is disposed on the second cabinet door 3 to seal the connection between the first column portion 122 and the second cabinet door 3.

[0078] In other words, the third seal 71 and the fourth seal 72 are located on the first column portion 122 and the second cabinet door 3, respectively, providing a double seal at the connection between the second cabinet door 3 and the first column portion 122. Compared to a single seal structure, this double-seal structure can more effectively prevent external substances (such as dust and moisture) from entering the cabinet 1. For example, in some places with high environmental requirements, such as energy storage cabinets and computer rooms, even if a small gap appears in one seal, the other seal can still provide protection, greatly improving the sealing performance of the cabinet 1.

[0079] In this embodiment, such as Figure 7 As shown, the first column portion 122 has a second snap-fit ​​plate 1224, and the third sealing member 71 is provided with a third snap-fit ​​groove 711. At least a portion of the second snap-fit ​​plate 1224 is snapped into the third snap-fit ​​groove 711. That is to say, in this embodiment, the third sealing member 71 and the second snap-fit ​​plate 1224 are snap-fit ​​connected, which is the same as the connection method of the first sealing member 61 and the first snap-fit ​​plate 1223 in the above-mentioned technical solutions. Therefore, the two can achieve the same technical effect, which will not be described in detail here.

[0080] It should be noted that, as Figure 7 As shown, the first column part 122 is roughly U-shaped, having a first base plate and two side plates connected to the two ends of the first base plate in the first direction X. After the two side plates and the first base plate are connected, they enclose an installation space 1221. Each side plate has a flange at the end facing away from the first base plate, and the two flanges extend toward each other. One of the flanges is used to form a first snap-fit ​​plate 1223, and the other flange is used to form a second snap-fit ​​plate 1224.

[0081] In this embodiment, such as Figure 4As shown, a protruding post 32 protrudes from the side of the second cabinet door 3 facing the energy storage compartment 11. A fourth sealing element 72 is connected to the protruding post 32. When the second cabinet door 3 is locked to the cabinet body 1, the fourth sealing element 72 is in close contact with the first column portion 122. Specifically, the fourth sealing element 72 is adhered to the protruding post 32, and the protruding post 32 is positioned so that the fourth sealing element 72 is in a protruding position. When the second cabinet door 3 is closed, the fourth sealing element 72 on the protruding post 32 can fit more tightly against the corresponding part of the first column portion 122, thereby enhancing the sealing effect at that location.

[0082] For example, such as Figure 4 As shown, the fourth seal 72 is bonded to the protrusion 32, which provides a clear mounting position for the fourth seal 72. During installation, installers can easily bond the fourth seal 72 to the protrusion 32 without the need for complex measuring or positioning tools. This design simplifies the installation process, improves installation efficiency, and reduces installation costs.

[0083] Or, such as Figure 8 As shown, another installation method for the fourth seal 72 is provided. Specifically, the fourth seal 72 is provided with a fourth snap-fit ​​groove 721, and at least a portion of the protrusion 32 is snapped into the fourth snap-fit ​​groove 721. That is to say, in this embodiment, the fourth seal 72 and the protrusion 32 are snapped together, which is the same as the connection method between the first seal 61 and the first snap-fit ​​plate 1223 in the above-mentioned technical solutions. Therefore, the two can achieve the same technical effect, and will not be described in detail here.

[0084] Or, as Figure 9 As shown, when the second sealing structure 7 seals the connection between the first column portion 122 and the second cabinet door 3, and between the second column portion 123 and the second cabinet door 3, the second sealing structure 7 includes a third sealing element 71 and a fourth sealing element 72. The third sealing element 71 seals the connection between the first column portion 122 and the second cabinet door 3, and the fourth sealing element 72 seals the connection between the second column portion 123 and the second cabinet door 3. The third sealing element 71 and the fourth sealing element 72 are located on the first column portion 122 and the second column portion 123, respectively, providing a double seal at the connection between the second cabinet door 3 and the column 12. Compared with a single sealing structure, this double sealing structure can more effectively prevent external substances (such as dust, moisture, etc.) from entering the cabinet 1. For example, in some places with high environmental requirements, such as energy storage cabinets and computer rooms, even if a small gap appears in one seal, the other seal can still provide protection, greatly improving the sealing performance of the cabinet 1.

[0085] Specifically, a second mounting plate 125 is connected to the outer side of the second column portion 123, and the fourth sealing element 72 is connected to the second mounting plate 125. When the second cabinet door 3 is locked to the cabinet body 1, the fourth sealing element 72 is in close contact with the second cabinet door 3. This method effectively fills the gap between the second cabinet door 3 and the second column portion 123, preventing dust, moisture, noise, etc., from entering the cabinet body 1 through the gap. Furthermore, the transition through the second mounting plate 125 allows for better adjustment of the position and fit of the fourth sealing element 72, thereby achieving a more optimized sealing effect.

[0086] In this embodiment, the fourth sealing element 72 and the second mounting plate 125 are snap-fitted together, which is the same as the connection method between the first sealing element 61 and the first snap-fit ​​plate 1223 in the above-mentioned technical solutions. Therefore, the two can achieve the same technical effect, which will not be described in detail here.
