[0022] The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see also Figures 1 to 12 One embodiment of this application provides an outdoor cabinet including a cabinet body 10, a first reinforcing structural component 31, and a second reinforcing structural component 32. The cabinet body 10 serves as a support structure for the first reinforcing structural component 31, the second reinforcing structural component 32, and various electrical components. The first reinforcing structural component 31 and the second reinforcing structural component 32 are respectively fixed to opposite sides of the cabinet body 10. The first reinforcing structural component 31 and the second reinforcing structural component 32 are used to cooperate with multiple lifting rings. After the multiple lifting rings are respectively installed and fixed to the first reinforcing structural component 31 and the second reinforcing structural component 32, the multiple lifting rings are connected and fixed to the ropes of the lifting equipment, thereby transporting the outdoor cabinet.

[0024] For cabinet 10, please refer to Figure 10 and Figure 11 See also Figures 1 to 7 In some embodiments, as shown in any of the accompanying drawings, the cabinet 10 has a cavity 10a for accommodating multiple battery packs. The cavity 10a has an opening that can be selectively closed or opened by rotating the cabinet door 22. Furthermore, the cabinet 10 has multiple alignment holes 10c, and both the first reinforcing structural assembly 31 and the second reinforcing structural assembly 32 include multiple welding nuts 302. The multiple alignment holes 10c are respectively aligned with the multiple welding nuts 302 of the first reinforcing structural assembly 31 and the multiple welding nuts 302 of the second reinforcing structural assembly 32. Specifically, the cabinet 10 has an overall rectangular box structure, including a top plate 11, a bottom plate 12, a back plate 13, a first side plate 14, and a second side plate 15. The top plate 11 and the bottom plate 12 are arranged opposite each other, and the first side plate 14 and the second side plate 15 are arranged opposite each other. The first side plate 14, the back plate 13, and the second side plate 15 are connected in sequence. The top ends of the first side plate 14, the back plate 13, and the second side plate 15 are respectively connected to the perimeter of the top plate 11, and the bottom ends of the first side plate 14, the back plate 13, and the second side plate 15 are respectively connected to the perimeter of the bottom plate 12. The top plate 11, the bottom plate 12, the first side plate 14, the back plate 13, and the second side plate 15 together form the aforementioned open cavity 10a. The first side plate 14 and the second side plate 15 each have multiple spaced alignment holes 10c.

[0025] For example, such as Figure 3 As shown, the top plate 11 bends downward around its perimeter to form a edging 111.

[0026] For example, such as Figure 12 As shown, the left end of the base plate 12 bends upward to form the seventh fold 121, the right end of the base plate 12 bends upward to form the eighth fold 122, and the rear end of the base plate 12 bends upward to form the ninth fold 123.

[0027] For example, such as Figure 11 As shown, the left end of the back panel 13 is continuously bent to the left to form a first folded edge 131, and the right end of the back panel 13 is continuously bent to the right to form a second folded edge 132.

[0028] For example, continue as follows Figure 11As shown, the first side plate 14 includes a first side plate body 141, a third folded edge 142, and a fourth folded edge 143. The top end of the first side plate body 141 is fixed to the edge 111 of the top plate 11 by fasteners, but not limited to fasteners. The rear end of the first side plate body 141 is also fixed to the ninth folded edge 123 by fasteners, but not limited to fasteners. The third folded edge 142 is integrally formed at one end of the first side plate body 141 near the back plate 13, and the third folded edge 142 abuts against the first folded edge 131. The two are fixed by fasteners, but not limited to fasteners. The fourth folded edge 143 is integrally formed at the bottom end of the first side plate body 141, and the fourth folded edge 143 abuts against the seventh folded edge 121. The two are fixed by fasteners, but not limited to fasteners. The first side plate body 141 has a plurality of spaced-apart alignment holes 10c.

[0029] For example, continue as follows Figure 11 As shown, the second side plate 15 includes a second side plate body 151, a fifth folded edge 152, and a sixth folded edge 153. The top end of the second side plate body 151 is fixed to the edge 111 of the top plate 11 by fasteners, but not limited to fasteners. The rear end of the second side plate body 151 is also fixed to the ninth folded edge 123 by fasteners, but not limited to fasteners. The fifth folded edge 152 is integrally formed at the end of the second side plate body 151 near the back plate 13, and the fifth folded edge 152 abuts against the second folded edge 132. The two are fixed by fasteners, but not limited to fasteners. The sixth folded edge 153 abuts against the eighth folded edge 122. The two are fixed by fasteners, but not limited to fasteners. The second side plate body 151 has a plurality of spaced-apart alignment holes 10c.

[0030] The advantages of adopting the aforementioned technical solution are that the cabinet structure is relatively simple, uses fewer parts and has low manufacturing cost. Each board is joined by multiple folded edges and fixed with screws, which ensures connection strength while reducing welding workload. It is also easy to combine to form multiple waterproof surfaces, improving protection performance.

[0031] like Figures 1 to 6 As shown in any of the accompanying drawings, in some embodiments, the cabinet 10 includes a partition 16. The partition 16 is connected between the top plate 11 and the bottom plate 12 and is disposed opposite to the back plate 13. The partition 16 divides the opening of the cavity 10a into two side-by-side openings 10b. Exemplarily, the partition 16 is located in the middle of the opening, and the partition 16 evenly divides the opening of the cavity 10a into two openings 10b. The number of cabinet doors 22 is the same as the number of openings 10b, and there are also two cabinet doors 22. The two cabinet doors 22 are respectively hinged to the first side plate 14 and the second side plate 15. An opening 10b can be optionally closed or opened by rotating a cabinet door 22.

[0032] Furthermore, the front end of the edging 111 of the top plate 11 is continuously bent inward, downward, and outward to form two first sealing edges 112. The front end of the bottom plate 12 is continuously bent upward and outward to form two second sealing edges 124. The front end of the first side plate 14 is continuously bent to the right and outward to form a third sealing edge 144. The opposite ends of the partition plate 16 are bent outward to form two fourth sealing edges 161 respectively. The front end of the second side plate 15 is continuously bent to the right and outward to form a fifth sealing edge 154. A first sealing edge 112, a second sealing edge 124, a third sealing edge 144, and a fourth sealing edge 161 together form an opening 10b. Another first sealing edge 112, another second sealing edge 124, a fifth sealing edge 154, and another fourth sealing edge 161 together form another opening 10b. A cabinet door 22 is fixed to the third sealing edge 144 by an embedded hinge, and another cabinet door 22 is also fixed to the fifth sealing edge 154 by an embedded hinge. Furthermore, the gap between the cabinet door and the periphery of the opening is sealed by foam strips on the inner door frame of each cabinet door 22.

[0033] Continue as Figure 10As shown, in some embodiments, the cabinet 10 includes multiple first side beams 17, multiple second side beams 18, multiple intermediate beams 19, a first tray assembly 20, and a second tray assembly 21. Along the height direction of the outdoor cabinet, the multiple first side beams 17 are spaced apart on the first side panel 14, the multiple second side beams 18 are spaced apart on the second side panel 15 along the height direction of the outdoor cabinet, and the multiple intermediate beams 19 are all fixed between the back panel 13 and the partition plate 16, and are spaced apart. The first tray assembly 20 and the second tray assembly 21 are arranged side-by-side in the cavity 10a, and are respectively exposed in their respective openings 10b. Both the first tray assembly 20 and the second tray assembly 21 include four uprights 101 and multiple sets of battery trays 102. The four uprights 101 are rectangularly distributed, and the multiple sets of battery trays 102 are respectively connected to the four uprights 101, and are spaced apart along the height direction of the outdoor cabinet. In this design, the two uprights 101 of the first tray assembly 20 near the first side plate 14 are fixed to multiple first side beams 17 via crossbeam supports, while the two uprights 101 of the first tray assembly 20 away from the first side plate 14 are fixed to multiple intermediate crossbeams 19. Similarly, the two uprights 101 of the second tray assembly 21 near the second side plate 15 are also fixed to multiple second side beams 18 via crossbeam supports, and the two uprights 101 of the second tray assembly 21 away from the second side plate 15 are also fixed to multiple second side beams 18. In this technical solution, the cavity 10a is divided into left and right compartments that are interconnected, facilitating the series and parallel connection of various battery packs, reducing cabling, and lowering costs. Furthermore, the various types of crossbeams and uprights 101 are connected longitudinally and transversely, resulting in a compact layout, high utilization of the internal space of the cavity 10a, and improved support strength within the cabinet.

[0034] Please combine Figure 8 See also Figure 1 To facilitate user assembly and maintenance of the battery packs housed within the cavity 10a, in some embodiments, the outdoor cabinet includes multiple busbar connection modules 40. Each busbar connection module 40 includes a transparent cover 401, a module frame 402, a busbar 403, and multiple terminals 404. The busbar 403 is screwed to the bottom of the module frame 402 using insulated nuts, and the multiple terminals 404 are screwed into the screw holes of the busbar 403 using multiple screws. The transparent cover 401 covers the top of the module frame 402. The module frame 402 is used to cooperate with the cabinet 10 to fix the busbar module to the cabinet 10, and the multiple terminals 404 are used for passing and fixing the connection cables of each battery pack.

[0035] Multiple busbar connection modules 40 are respectively fixed to the surface of the first side plate 14 facing the cavity 10a and the surface of the second side plate 15 facing the cavity 10a. And / or, multiple busbar connection modules 40 are respectively fixed between multiple intermediate crossbeams 19. Exemplarily, at least one busbar connection module 40 is fixed to the side of the first side plate body 141 near the cabinet door 22, at least one busbar connection module 40 is fixed to the side of the second side plate body 151 near the cabinet door 22, and / or, at least one busbar connection module 40 is fixed between two adjacent intermediate crossbeams 19 by a bracket. Compared to related technologies where the busbar is directly installed on the cabinet 10 using guide rails, resulting in exposed connecting cables, this technical solution uses modular busbar connection modules 40, which can be added or removed as needed to facilitate overall installation, disassembly, and maintenance.

[0036] Please combine Figure 9 See also Figure 1 To enhance the safety performance of outdoor cabinets, in some embodiments, the outdoor cabinet includes multiple power distribution boxes 50, each equipped with a circuit breaker 501. The circuit breaker 501 automatically disconnects the circuit when an overload or short circuit occurs. The multiple power distribution boxes 50 are respectively fixed to the surfaces of the first side plate 14 and the second side plate 15 facing the cavity 10a. And / or, multiple distribution boxes are respectively fixed between multiple intermediate crossbeams 19. Exemplarily, at least one power distribution box 50 is fixed to the side of the first side plate body 141 near the cabinet door 22, at least one power distribution box 50 is fixed to the side of the second side plate body 151 near the cabinet door 22, and / or, at least one power distribution box 50 is fixed between two adjacent intermediate crossbeams 19 by a bracket.

[0037] For the first reinforcing structural component 31 and the second reinforcing structural component 32. For example... Figure 3 As shown, in some embodiments, both the first reinforcing structural component 31 and the second reinforcing structural component 32 include a structural reinforcing plate 301 and a plurality of weld nuts 302.

[0038] Multiple welded nuts 302 of the first reinforcing structural component 31 are fixed to the surface of the first side plate 14 facing the cavity 10a via the structural reinforcing plate 301 of the first reinforcing structural component 31. Multiple welded nuts 302 of the second reinforcing structural component 32 are fixed to the surface of the second side plate 15 facing the cavity 10a via the structural reinforcing plate 301 of the second reinforcing structural component 32. The screw holes of the multiple welded nuts 302 correspond one-to-one with the multiple alignment holes 10c, and the screw holes of each welded nut 302 are used for screwing and fixing multiple lifting eyelets.

[0039] Exemplarily, the structural reinforcing plate 301 of the first reinforcing structural assembly 31 can be fixed to the surface of the first side plate body 141 facing the cavity 10a by means of welding, but not limited to welding. The structural reinforcing plate 301 of the first reinforcing structural assembly 31 is close to the top end of the first side plate body 141. The first reinforcing structural assembly 31 has two welding nuts 302, both of which are welded to the surface of the structural reinforcing plate 301 facing the cavity 10a. Corresponding to the two welding nuts 302 of the first reinforcing structural assembly 31, the first side plate body 141 has two alignment holes 10c, which are aligned one-to-one with the screw holes of the two welding nuts 302.

[0040] Exemplarily, the structural reinforcing plate 301 of the second reinforcing structural assembly 32 can be fixed to the surface of the second side plate body 151 facing the cavity 10a by welding, but not limited to welding. The structural reinforcing plate 301 of the second reinforcing structural assembly 32 is located near the top end of the second side plate body 151. The second reinforcing structural assembly 32 also has two welding nuts 302, both of which are welded to the surface of the structural reinforcing plate 301 facing the cavity 10a. Corresponding to the two welding nuts 302 of the aforementioned second reinforcing structural assembly 32, the second side plate body 151 has two alignment holes 10c, which are aligned one-to-one with the screw holes of the two welding nuts 302.

[0041] Furthermore, the screw holes of the plurality of welded nuts 302 in the first reinforcing structural component 31 are blind holes, and / or, the screw holes of the plurality of welded nuts 302 in the second reinforcing structural component 32 are blind holes. This further reduces the possibility of water seeping into the outdoor cabinet and causing short circuits or other malfunctions in electrical components such as the energy storage battery pack, thereby further improving the safety of the battery energy storage system.

[0042] Continue as Figure 1 As shown, to reduce water droplets falling into the screw holes of each weld nut 302 and subsequently accumulating water in those holes, in some embodiments, the outdoor cabinet includes multiple sealing elements 60. Each sealing element 60 passes through a corresponding alignment hole 10c and engages with a corresponding weld nut 302. Exemplarily, each sealing element 60 is a sealing screw, which passes through the corresponding alignment hole 10c and is screwed into the screw holes of the weld nuts 302.

[0043] In summary, the outdoor cabinet involved in this application relocates the lifting ring mounting holes originally located around the top of the cabinet to the opposite sides of the cabinet. The first side plate 14, where the welding nut 302 is located, is structurally reinforced using a first reinforcing structural component 31, and the second side plate 15, where the welding nut 302 is located, is structurally reinforced using a second reinforcing structural component 32. This ensures that the structural strength of the outdoor cabinet remains essentially unchanged while reducing the accumulation of water droplets in the screw holes of the welding nut 302. This reduces the likelihood of water seeping into the interior of the outdoor cabinet and causing short circuits or other malfunctions in electrical components such as the energy storage battery pack, thereby improving the safety of the battery energy storage system.

[0044] Furthermore, this outdoor cabinet features a double-door design with left and right compartments within a 10a cavity, supporting simultaneous operation from both sides. It is suitable for installing multiple battery packs simultaneously, reducing the number of connecting cables between cabinets and improving maintenance efficiency. The power distribution box and busbar connection modules are modular and highly integrated, reducing deployment costs. The cabinet's panels utilize overlapping and folded edges to ensure mechanical strength and waterproof performance.

[0045] Based on the same technical concept, this utility model embodiment also provides a battery energy storage system, including the outdoor cabinet mentioned in any of the above embodiments and multiple battery packs, which are housed within the cavity 10a, and the battery packs are connected in series, parallel, or mixed connections. Since the specific structure, functional principles, and technical effects of the outdoor cabinet have been detailed above, they will not be repeated here. Any technical content related to the outdoor cabinet can be found in the preceding description of the outdoor cabinet.

[0046] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
