Detailed Implementation

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0048] The output terminal base plays a crucial role in the battery pack, acting as a bridge connecting the internal current of the battery pack to the external circuitry. It ensures that current flows stably and efficiently from the battery pack to power external devices. In related technologies, mounting slots are typically created in the side wall of the enclosure to house the output terminal base. However, this mounting method compromises the enclosure's structure, reducing its strength.

[0049] In view of this, the present invention proposes a box body. Figures 1 to 9 This is a structural schematic diagram of an embodiment of the enclosure provided by this utility model. The enclosure provided by this utility model enables the installation of the output stage base while ensuring sufficient strength. The enclosure will be described in detail below with reference to the main accompanying drawings.

[0050] Reference Figures 1 to 3 The enclosure 100 includes a main body 10 and a support 20. The main body 10 forms a first electrical compartment 102. The support 20 includes a connecting part 201 and a supporting part 202 connected to each other. The connecting part 201 and the supporting part 202 are arranged at an angle. The connecting part 201 is used to weld and fix to the side wall of the first electrical compartment 102. The supporting part 202 is used to support and connect to the output stage base 200.

[0051] In this embodiment of the invention, the enclosure 100 consists of a main body 10 and a support 20. The main body 10 and the support 20 are separate components, simplifying the manufacturing process of the main body 10. The support 20 is welded to the side wall of the first electrical compartment 102 of the main body 10 via a connecting part 201. This welded connection design avoids the need for connection holes in the main body 10, ensuring the integrity of the main structure of the enclosure 100 and guaranteeing sufficient strength. The connecting part 201 and the supporting part 202 are arranged at an angle, which helps optimize the spatial layout of the main body 10. The support portion 202 of the bracket 20 is used to support and connect the output stage base 200. This design effectively distributes the load of the output stage base 200 onto the bracket 20 and ensures a stable connection between the output base and the bracket 20. In addition, the output stage base 200 is supported by and connected to the support portion 202, so that the operations of placing the output stage base 200 and connecting the output stage base 200 are both performed on the support portion 202, simplifying the operation steps and making the connection operation simple.

[0052] Reference Figure 2 and Figure 3 The support section 202 includes multiple support plates 2021 spaced apart along the width direction of the enclosure body 10. Each support plate 2021 is connected to the connecting section 201. Each support plate 2021 extends along the length direction of the enclosure body 100 and supports and connects to the output stage base 200. The design of multiple support plates 2021 effectively distributes the load of the output stage base 200 on the enclosure body 10, which helps reduce the pressure at each load point, thereby reducing the risk of damage to the enclosure body 10 structure due to localized overload. The extension of the support plates 2021 along the length direction of the enclosure body 100 increases the contact area with the output stage base 200, thereby improving the stability of the connection. This design helps prevent the output stage base 200 from shaking or shifting during operation, ensuring stable operation of the equipment. The spaced arrangement of the support plates 2021 provides more installation space for other components or assemblies without increasing the overall size of the enclosure body 100. This design helps optimize the internal layout of the enclosure body 100 and improve space utilization. In addition, the spaced arrangement of the bearing plates 2021 can reduce the weight of the bracket 20 to some extent.

[0053] It should be noted that the output stage base 200 can be provided as one, two, or more; specifically, this application does not limit this. When one output stage base 200 is provided, the output stage base 200 is supported and connected by multiple carrier plates 2021. When two or more output stage bases 200 are provided, the two or more output stage bases 200 are respectively provided on multiple carrier plates 2021.

[0054] Reference Figure 3In one embodiment, the connecting part 201 includes multiple mounting plates 2011 and multiple connecting arms 2012. Each mounting plate 2011 is welded and fixed to the side wall of the first electrical compartment 102. The multiple connecting arms 2012 are provided between each two adjacent mounting plates 2011. The two ends of the connecting arms 2012 are respectively connected to the two adjacent mounting plates 2011. The multiple support plates 2021 and / or multiple mounting plates 2011 are connected to the multiple support plates 2021. Thus, the welding and fixing of the mounting plates 2011 to the side wall of the first electrical compartment 102 and the connection of the connecting arms 2012 between adjacent mounting plates 2011 form a stable frame structure. This structure can effectively resist external impacts and vibrations and ensure the stable installation of the output stage base 200. The design of multiple mounting plates 2011 and multiple connecting arms 2012 helps to distribute the load of the load-bearing plate 2021 on the connection part 201. By increasing the number of connection points, the load can be more effectively distributed throughout the connection part 201, avoiding structural damage caused by single-point overload. Welding is a high-strength connection method that ensures a firm connection between the mounting plate 2011 and the electrical compartment sidewall. Simultaneously, the multiple connecting arms 2012 connecting the multiple mounting plates 2011 into a single unit ensures that the entire connection part 201 maintains a stable shape and position under external forces. The presence of the connecting arms 2012 helps to distribute the load across the entire connection part 201, rather than concentrating it on a single mounting plate 2011. This load-distribution effect extends the service life of the connection part 201 and reduces structural damage caused by single-point overload. Furthermore, the connection arrangement of multiple connecting arms 2012 and multiple mounting plates 2011 can, to some extent, reduce the weight of the bracket 20.

[0055] It should be noted that, in one embodiment, the connecting arm 2012 may only be abutted against the side wall of the first electrical compartment 102. In another embodiment, the connecting arm 2012 may only be welded to the side wall of the first electrical compartment 102. In other embodiments, the connecting arm 2012 may also be glued to the side wall of the first electrical compartment 102 using adhesive or double-sided tape. Specifically, this application does not limit this.

[0056] Reference Figure 3 In one embodiment, multiple mounting plates 2011 are correspondingly arranged and connected to multiple support plates 2021. This one-to-one correspondence and tight connection between the mounting plates 2011 and support plates 2021 forms a more stable structure, which helps the bracket 20 resist external impacts and vibrations. The one-to-one connection method makes it easier for the operator to identify the correspondence between each mounting plate 2011 and support plate 2021 and to install the output stage base 200 in the predetermined position. This helps improve installation efficiency and reduce rework caused by installation errors.

[0057] Reference Figure 3 In one embodiment, the connecting portion 201 and the supporting portion 202 are integrally formed. This integral design eliminates seams or connection points between the connecting portion 201 and the supporting portion 202, thereby eliminating potential weaknesses. This design significantly improves the overall strength and rigidity of the support 20 structure, enabling it to better resist external impacts and vibrations. The integral design helps to distribute stress more evenly between the connecting portion 201 and the supporting portion 202. This uniform stress distribution reduces the risk of structural failure due to stress concentration, thus improving structural stability. The integral design simplifies the manufacturing process, reducing the number of parts and fasteners required for assembly. This not only reduces manufacturing costs but also improves production efficiency. Furthermore, the reduced assembly steps also lower the quality risk caused by assembly errors. The integral design reduces the risk of structural failure due to loose or damaged connection points, significantly improving structural durability and extending service life. The one-piece molding design makes the transition between the connecting part 201 and the supporting part 202 smoother and more natural, without any abrupt seams or connection points. This design not only improves the overall aesthetics of the product, but also enhances the user's visual experience.

[0058] Reference Figure 2 In one embodiment, the support portion 202 has a first side facing away from the bottom of the first electrical compartment 102. This first side is used to abut against the bottom of the output stage base 200, thus providing support for the output stage base 200 and ensuring its stability to prevent wobbling before fixing. The support portion 202 is provided with a mounting hole 2022, which is adapted to insert a first connector for connection with the output stage base 200. Thus, through the cooperation of the mounting hole 2022 and the first connector, a firm connection can be formed between the support portion 202 and the output stage base 200. This connection not only improves the stability of the connection between the output stage base 200 and the bracket 20, but also helps to resist external impacts and vibrations, ensuring the normal operation of the output stage base 200.

[0059] It should be noted that the type of the first connector can be selected as needed. For example, in one embodiment, the first connector passes through the mounting hole 2022 and can be threadedly connected to the output stage base 200. In another embodiment, the first connector passes through the mounting hole 2022 and can be snap-fitted to the output stage base 200. Specifically, this application does not limit the connection method between the first connector and the output stage base 200.

[0060] In one embodiment, multiple mounting holes 2022 are provided, spaced apart, with each mounting hole 2022 extending along the thickness direction of the housing body 10. This arrangement of multiple mounting holes necessitates the provision of multiple corresponding first connectors, which pass through the mounting holes 2022 and connect to the output stage base 200, thus ensuring a stable installation of the output stage base 200. Furthermore, this distributed fixing method helps resist external impacts and vibrations, ensuring the stable operation of the output stage base 200. The spaced arrangement of multiple mounting holes 2022 effectively distributes the load, preventing structural damage caused by excessive stress at a single point, thus extending the service life of the bracket 20 and the output stage base 200. Multiple mounting holes 2022 provide more installation options, making the installation process more flexible. Simultaneously, by adjusting the position of the first connectors in different mounting holes 2022, the position of the output stage base 200 on the support portion 202 can be easily fine-tuned. The mounting holes 2022 extend along the thickness of the housing body 10, which helps to optimize the layout of the internal space. This design ensures that the first connector does not occupy additional horizontal or vertical space, thereby improving the compactness and space utilization of the electrical compartment.

[0061] Reference Figures 4 to 6 In one embodiment, the box body 10 includes two side beams 11, two end plates 19, multiple longitudinal beams 12, and a bottom plate 18. The two side beams 11 are arranged opposite each other and spaced apart along the width direction of the box body 10, and each side beam 11 extends along the length direction of the box body 10. The two end plates 19 extend along the width direction of the box body 10 and are spaced apart along the length direction of the box body 10. Each end plate 19 is connected to the end of the two side beams 11. The multiple longitudinal beams 12 are spaced apart between the two end plates 19 along the length direction of the box body 10, and each longitudinal beam 12 extends along the width direction of the box body 10. Each longitudinal beam 12 is connected to two side beams 11 at both ends. The bottom plate 18 is connected to the two side beams 11, two end plates 19, and multiple longitudinal beams 12, so that the bottom plate 18, the two side beams 11, the two end plates 19, and the multiple longitudinal beams 12 together enclose multiple compartments 101 spaced apart. The multiple compartments 101 include at least one first electrical compartment 102. In this way, the combination of the two side beams 11, the two end plates 19, the multiple longitudinal beams 12, and the bottom plate 18 forms a robust frame structure. This design significantly enhances the overall rigidity of the enclosure body 10, enabling it to resist external impacts and vibrations. The design of multiple compartments 101 allows different functional modules to be placed in different compartments 101, thereby achieving functional zoning. This design facilitates equipment maintenance and management and improves work efficiency.

[0062] It should be noted that the base plate 18 is welded and fixed to multiple longitudinal beams 12 and / or two side beams 11. This connection method greatly enhances the overall rigidity of the housing 100, enabling it to better resist external impacts and vibrations while meeting structural strength requirements. The base plate 18, multiple longitudinal beams 12, and two side beams 11 together form multiple receiving slots. The design of multiple receiving slots provides an installation space for the battery module, making the installation of the battery module more convenient and accurate. The design of multiple receiving slots effectively supports and fixes the battery module within the housing 100, reducing the risk of deformation caused by the weight of the battery module or vehicle movement.

[0063] Reference Figure 4 and Figure 5 In one embodiment, the housing 100 further includes multiple reinforcing members 13, each corresponding to the end of a plurality of longitudinal beams 12. Each reinforcing member 13 includes a connecting seat 131 and a plug-in portion 132 protruding from the connecting seat 131. The connecting seat 131 is fixedly connected to the corresponding side beam 11, and the plug-in portion 132 is plugged into and fixedly connected to the end of the corresponding longitudinal beam 12. The reinforcement members 13 significantly enhance the strength of the connection between the longitudinal beams 12 and the side beams 11, improving the overall rigidity of the housing 100. The plugging and fixed connection of the plug-in portion 132 to the end of the longitudinal beam 12 ensures the reliability and stability of the connection. This connection method is less prone to loosening or falling off, improving the overall safety of the housing 100. The plugging of the plug-in portion 132 into the longitudinal beam 12 not only simplifies the assembly process but also increases the contact area between the plug-in portion 132 and the longitudinal beam 12, increasing the connection strength between the longitudinal beam 12 and the side beam 11, further improving the stability of the overall frame structure. The connecting seat 131 of the reinforcement 13 is fixedly connected to the side beam 11, and the plug-in part 132 is plugged into the longitudinal beam 12 and fixed with multiple second connecting parts 14. This design enables the reinforcement 13 to effectively transmit and disperse external forces, thereby enhancing the bending and torsional resistance of the frame.

[0064] Reference Figure 5 , Figure 7 and Figure 8 In one embodiment, the insertion part 132 of the reinforcement 13 has two first sidewalls 1321 arranged opposite to each other along the second direction. The two first sidewalls 1321 are fixedly connected to the corresponding longitudinal beam 12 through a plurality of second connectors 14. Thus, since the two first sidewalls 1321 are arranged opposite to each other along the second direction, there is a large operating space when the insertion part 132 is fixedly connected to the corresponding longitudinal beam 12 through the second connectors 14, making the connection and fixing operation of the insertion part 132 and the longitudinal beam simple.

[0065] Reference Figure 7In one embodiment, the connecting seat 131 is screwed to the side beam 11 via multiple first screw fasteners 15. This screw-fixing method can withstand significant tensile and shear forces, ensuring the strength and stability of the connection between the connecting seat 131 and the side beam 11. The screw-fixing has a self-locking function, effectively preventing loosening between the connecting seat 131 and the side beam 11 due to vibration or external forces. The screw-fixing method is relatively simple and allows for quick connection between the connecting seat 131 and the side beam 11, improving installation efficiency. The screw-fixing method also allows for disassembly and reassembly of the connecting seat 131 and the side beam 11 as needed.

[0066] It should be noted that the connection method between the connecting seat 131 and the side beam 11 can be selected as needed. For example, in one embodiment, the connecting seat 131 and the side beam 11 can also be fixed by screws or welding. This improves the stability of the connecting seat 131 and the side beam 11. In another embodiment, the connecting seat 131 and the side beam 11 can also be fixed by welding or connected by a pin. In other embodiments, the connecting seat 131 and the side beam 11 can also be fixed by welding and connected by a pin. Specifically, this application does not limit this.

[0067] Reference Figure 9 In one embodiment, the plurality of second connectors 14 include a plurality of second screw connectors 141, each second screw connector 141 fixing the first sidewall 1321 to the corresponding longitudinal beam 12. This screw-on fixing method can withstand greater tensile and shear forces, ensuring the strength and stability of the connection between the insertion part 132 and the longitudinal beam 12. The screw-on fixing has a self-locking function, effectively preventing loosening between the insertion part 132 and the longitudinal beam 12 due to vibration or external forces. The screw-on fixing method is relatively simple and can quickly achieve the connection between the insertion part 132 and the longitudinal beam 12, improving installation efficiency. The screw-on fixing method allows the insertion part 132 and the longitudinal beam 12 to be disassembled as needed.

[0068] It should be noted that the connection method between the plug-in portion 132 and the longitudinal beam 12 can be selected as needed. For example, in one embodiment, the plug-in portion 132 and the longitudinal beam 12 can also be fixed by screws or welding. This improves the stability of the plug-in portion 132 and the longitudinal beam 12. In another embodiment, the plug-in portion 132 and the longitudinal beam 12 can also be fixed by welding or connected by a pin. In other embodiments, the plug-in portion 132 and the longitudinal beam 12 can also be fixed by welding and connected by a pin. Specifically, this application does not limit this.

[0069] Reference Figure 8 and Figure 9In one embodiment, the longitudinal beam 12 has two second sidewalls 121 arranged opposite each other along a second direction. Each second sidewall 121 has a plurality of first through holes 161 extending through it along the second direction. Each first sidewall 1321 has a plurality of first threaded holes 171 extending through it along the second direction. The plurality of first threaded holes 171 correspond one-to-one with the plurality of first through holes 161. The threaded ends of a plurality of second threaded connectors 141 pass through the plurality of first through holes 161 and are threadedly connected to the corresponding plurality of first threaded holes 171. Thus, the threaded connection method can withstand greater tensile and shear forces, ensuring the strength and stability of the connection between the insertion part 132 and the longitudinal beam 12. The threaded connection has a self-locking function, effectively preventing loosening between the insertion part 132 and the longitudinal beam 12 due to vibration or external forces. The threaded connection method is relatively simple and can quickly achieve the connection between the insertion part 132 and the longitudinal beam 12, improving installation efficiency. The threaded connection method allows the insertion part 132 and the longitudinal beam 12 to be disassembled as needed.

[0070] Reference Figure 7 In one embodiment, the diameter of the first through hole 161 decreases at least partially along the direction from the second sidewall 121 to the first sidewall 1321. The second screw connector 141 includes a first tapered countersunk bolt. The threaded end of the first tapered countersunk bolt is adapted to be threaded into the first threaded hole 171, and the head of the first tapered countersunk bolt is adapted to be recessed into the first through hole 161. Thus, the head of the first tapered countersunk bolt is designed to be tapered, which can fit into the first through hole 161 with decreasing diameter. When the bolt is installed in place, the head of the first tapered countersunk bolt can be recessed into the hole and will not protrude from the surface of the second sidewall 121, thereby achieving an aesthetically pleasing assembly effect. Since the head of the first tapered countersunk bolt does not protrude from the surface of the second sidewall 121, safety hazards such as scratches and collisions caused by the bolt head during use can be avoided. The countersunk design allows the head of the first tapered countersunk bolt to form a tighter contact with the second sidewall 121, which helps to enhance the stability of the connection and prevent the first tapered countersunk bolt from loosening due to vibration or external force. The compatibility between the head of the first tapered countersunk bolt and the first through hole 161 makes it easier to align the first tapered countersunk bolt with the threaded hole during installation, improving installation efficiency. Because the head of the first tapered countersunk bolt can be recessed into the first through hole 161, the utilization rate of the space enclosed by the frame is improved.

[0071] Reference Figure 7In one embodiment, a groove 1322 is provided at the end of the plug portion 132 away from the connector 131. The groove 1322 communicates with a plurality of first threaded holes 171. Thus, due to the presence of the groove 1322, the installer can more easily pass the second screw 141 through the corresponding first threaded hole 171 and quickly complete the tightening operation, thereby improving installation efficiency. The design of the groove 1322 helps reduce stress concentration in the plug portion 132 during the connection process. When the second screw 141 is tightened, the groove 1322 can disperse some of the stress, thereby reducing the risk of cracking or damage to the plug portion 132. The presence of the groove 1322 can reduce the weight of the fastener.

[0072] Reference Figure 5 and Figure 7 In one embodiment, the connecting seat 131 is provided with a plurality of second through holes 162 along a first direction, and the plurality of second through holes 162 are located on both sides of the insertion portion 132 along a second direction. Each side beam 11 is provided with a plurality of second threaded holes 172 corresponding to the plurality of second through holes 162. The threaded ends of the plurality of first threaded members 15 pass through the plurality of second through holes 162 and are threadedly connected to the corresponding plurality of second threaded holes 172. In this way, the screw-on fixing method can withstand greater tensile and shear forces, ensuring the strength and stability of the connection between the connecting seat 131 and the side beam 11. The screw-on fixing has a self-locking function, which can effectively prevent the connecting seat 131 and the side beam 11 from loosening due to vibration or external force. The screw-on fixing method is relatively simple and can quickly realize the connection between the connecting seat 131 and the side beam 11, improving installation efficiency. The screw-on fixing method allows the connecting seat 131 and the side beam 11 to be disassembled as needed.

[0073] Reference Figure 7In one embodiment, the diameter of the second through hole 162 decreases at least partially along the direction from the insertion part 132 to the connecting seat 131. The second screw connector 141 includes a second tapered countersunk bolt. The threaded end of the second tapered countersunk bolt is adapted to be threaded into the second threaded hole 172. The head of the first tapered countersunk bolt is adapted to be recessed into the second through hole 162. Thus, the head of the second tapered countersunk bolt is designed to be tapered, which can fit into the second through hole 162 with a decreasing diameter. When the second tapered countersunk bolt is installed in place, its head can be recessed into the hole and will not protrude from the surface of the connecting seat 131, thereby achieving an aesthetically pleasing assembly effect. Since the head of the second tapered countersunk bolt does not protrude from the surface of the connecting seat 131, safety hazards such as scratches and collisions caused by the head of the second tapered countersunk bolt during use can be avoided. Because the head of the second tapered countersunk bolt matches the decreasing diameter design of the second through hole 162, when the second tapered countersunk bolt is tightened, its head fits more tightly against the inner wall of the second through hole 162, thereby enhancing the stability and reliability of the connection between the side beam 11 and the connecting seat 131. The tapered head design of the second tapered countersunk bolt helps to disperse stress during the connection process, reducing the risk of cracking or damage to the connection part 201 due to stress concentration. The compatibility between the head of the second tapered countersunk bolt and the second through hole 162 makes it easier to align the second tapered countersunk bolt with the second threaded hole 172 during installation, improving installation efficiency. Since the head of the second tapered countersunk bolt can be recessed into the second through hole 162, the utilization rate of the space formed by the frame enclosure is improved.

[0074] Reference Figure 5 and Figure 8 In one embodiment, the connecting seat 131 is further provided with a plurality of welding holes 1311 along a first direction. The plurality of welding holes 1311 are distributed on both sides of the insertion portion 132 along a second direction. The plurality of welding holes 1311 are adjacent to the periphery of the side beam 11 for welding and fixing with the side beam 11. In this way, the connection strength between the connecting seat 131 and the side beam 11 is improved, so that the frame edge can withstand greater loads and vibrations. The welding holes 1311 distributed on both sides of the insertion portion 132 along the second direction help to disperse the stress during the welding process between the connecting seat 131 and the side beam 11, and avoid connection failure caused by stress concentration.

[0075] In one embodiment, the periphery of the connecting seat 131 is welded to the side beam 11, thereby improving the connection strength between the connecting seat 131 and the side beam 11, enabling the frame edge to withstand larger loads and vibrations. Fixing the periphery of the connecting seat 131 to the side beam 11 by welding effectively prevents displacement or deformation of the connecting seat 131 during use, thus ensuring the stability of the entire structure. The welded connection has good long-term stability, ensuring that the connection between the connecting seat 131 and the side beam 11 remains firmly in place.

[0076] It should be noted that the feature of welding the periphery of the welding hole 1311 to the side beam 11 and the feature of welding the periphery of the connecting seat 131 to the side beam 11 can be set separately or simultaneously. When set simultaneously, the connection between the connecting seat 131 and the side beam 11 is stable and firm.

[0077] The method of achieving the insertion fit between the end of the longitudinal beam 12 and the insertion part 132 can be selected as needed, referring to... Figure 9 In one embodiment, the end of the longitudinal beam 12 is provided with a plug-in hole 122, and the plug-in part 132 is inserted into the plug-in hole 122. The connecting seat 131 abuts against the end of the longitudinal beam 12. The matching design of the plug-in hole 122 and the plug-in part 132 makes the connection process between the plug-in part 132 and the longitudinal beam 12 simple and quick, thereby improving the connection efficiency. The tight fit between the plug-in hole 122 and the plug-in part 132 increases the contact area between the longitudinal beam 12 and the plug-in part 132, which can ensure the stability and reliability of the connection position 201 between the plug-in hole 122 and the plug-in part 132, and prevent structural failure at the connection point. The plug-in connection design helps to disperse the stress at the connection position 201, avoid structural damage caused by stress concentration, and thus improve the overall stability of the frame structure. The matching design of the plug-in hole 122 and the plug-in part 132 can ensure the precise positioning of the connection position 201, and avoid deviation or misalignment during the connection process. Precise fit and positioning help improve the quality of frame assembly and ensure the robustness and reliability of the 201-position connection.

[0078] In other embodiments, the end of the insertion portion 132 may be provided with an insertion hole 122, and the longitudinal beam 12 may be inserted into the insertion hole 122. In other embodiments, the insertion portion 132 may be provided with a first insertion hole 122, and the longitudinal beam 12 may be provided with a second insertion hole 122, with the end of the longitudinal beam 12 inserted into the first insertion hole 122 and the end of the insertion portion 132 inserted into the second insertion hole 122. Specifically, this application does not limit this to any particular embodiment.

[0079] Reference Figure 4 and Figure 6 In one embodiment, the first electrical compartment 102 is located between the end plate 19 and the longitudinal beam 12, and the connecting part 201 is welded to the longitudinal beam 12. By placing the first electrical compartment 102 between the end plate 19 and the longitudinal beam 12 and welding it to the longitudinal beam 12 using the connecting part 201, this design avoids directly drilling holes or making other forms of destructive connections on the longitudinal beam 12. In this way, the overall structure of the longitudinal beam 12 remains intact, avoiding strength reduction or safety hazards caused by damage. This design simplifies the installation process of the electrical compartment, eliminating the need for additional processing or treatment of the longitudinal beam 12. This reduces installation difficulty and cost while improving installation efficiency.

[0080] Reference Figure 1 and Figure 4 In one embodiment, the end plate 19 corresponding to the first electrical compartment 102 includes a mounting frame 191 and a cover plate 192. The mounting frame 191 is connected to the two side beams 11 and the bottom plate 18 respectively. The cover plate 192 is detachably connected to the mounting frame 191 and is used to cover the opening of the mounting frame 191. This detachable connection between the mounting frame 191 and the cover plate 192 allows for easy access to components inside the electrical compartment by simply removing the cover plate 192 when maintenance or replacement is needed. This significantly reduces maintenance difficulty and cost while improving maintenance efficiency. The cover plate 192 effectively prevents external contaminants such as dust and moisture from entering the electrical compartment, thus protecting the internal equipment from damage. The mounting frame 191 is connected to the two side beams 11 and the bottom plate 18, forming a stable support structure. This design improves the overall structural strength of the electrical compartment and enhances its ability to withstand external loads.
