[0034] In the embodiment of the present application, the energy storage box 100 is a box structure of the energy storage device, and the energy storage unit of the energy storage device is installed in the energy storage box 100.

[0035] The energy storage unit can be a battery, a battery module, a battery cell, etc.

[0036] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0037] The battery cells can be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc., which are not limited in the embodiments of the present application.

[0038] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity. When there are multiple battery cells, the multiple battery cells are connected in series, in parallel or in hybrid through a busbar.

[0040] In some embodiments, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are housed in the case.

[0041] The development of battery technology must take into account multiple design factors at the same time, such as energy density, cycle life, discharge capacity, charge and discharge rate and other performance parameters. In addition, the safety performance of the battery also needs to be considered.

[0042] In energy storage equipment, the energy storage box serves as the outer shell of the energy storage equipment to protect the energy storage unit. The energy storage unit is arranged in the energy storage box. The box body of the energy storage box is provided with mounting columns. The energy storage unit is installed on the mounting frame of the mounting columns. The existing energy storage box has poor structural strength. After the energy storage unit is installed on the mounting frame, the energy storage box is easily deformed under the action of the gravity of the energy storage unit, which affects the service life of the energy storage box.

[0043] In view of this, an embodiment of the present application provides an energy storage box, which includes a box body and an installation column. The box body defines an installation space. A mounting beam is provided in the installation space, and the mounting beam is fixed to the box body. The bottom wall of the installation space is a plate-like structure. The installation column is provided in the installation space, and the two ends of the installation column are fixedly connected to the mounting beam and the bottom wall of the installation space respectively.

[0044] In such an energy storage box, by setting the bottom wall of the installation space as a plate-like structure and fixing the two ends of the installation column to the installation beam and the bottom wall of the installation space respectively, the structural strength of the energy storage box can be improved, the risk of deformation of the energy storage box can be reduced, and the service life of the energy storage box can be increased.

[0045] The energy storage box 100 according to an embodiment of the present application is described below with reference to Figures 1 to 9. The energy storage device includes an energy storage unit and the energy storage box 100. The energy storage unit is installed in the energy storage box 100.

[0046] The energy storage box 100 according to an embodiment of the present application includes a box body 10 and mounting posts 20. The box body 10 defines an installation space 11. A mounting beam 12 is disposed within the installation space 11 and is located at the top of the installation space 11. The mounting beam 12 is fixed to the box body 10. The bottom wall 13 of the installation space 11 and the mounting beam 12 are opposed to and spaced apart from each other along the height of the energy storage box 100. The bottom wall 13 of the installation space 11 is a plate-like structure. The mounting posts 20 are disposed within the installation space 11, with their ends fixedly connected to the mounting beam 12 and the bottom wall 13 of the installation space 11, respectively.

[0047] As shown in FIG3 , the box body 10 defines an installation space 11. A mounting beam 12 is disposed within the installation space 11. Mounting beam 12 is located at the top of the installation space 11, vertically relative to the energy storage box 100 (i.e., along the Z direction in FIG3 ). Mounting beam 12 is fixedly connected to the box body 10. The mounting beam 12 and the box body 10 may be welded or bolted. A bottom wall 13 of the installation space 11 and the mounting beam 12 are disposed opposite each other along the height of the energy storage box 100. The bottom wall 13 of the installation space 11 and the mounting beam 12 are spaced apart along the height of the energy storage box 100. The bottom wall 13 of the energy storage box 100 and the bottom wall 13 of the installation space 11 are the same wall. The bottom wall 13 of the installation space 11 is a plate-like structure. It should be noted that the bottom wall 13 of the installation space 11 is a single, integral plate-like structure, or similar to a single, integral plate-like structure. The two ends of the mounting column 20 are fixedly connected to the mounting beam 12 and the bottom wall 13 of the mounting space 11 respectively. It can also be understood that the upper end of the mounting column 20 is fixedly connected to the mounting beam 12, and the lower end of the mounting column 20 is fixedly connected to the bottom wall 13 of the mounting space 11. The mounting column 20 and the mounting beam 12 and the bottom wall 13 of the mounting space 11 can be welded, and the mounting column 20 and the mounting beam 12 and the bottom wall 13 of the mounting space 11 can also be connected by bolts.

[0048] In the present application, by configuring the bottom wall 13 of the installation space 11 as a plate-like structure, the structural strength of the bottom wall 13 of the installation space 11 can be improved, and the supporting strength of the bottom wall 13 of the installation space 11 can be improved. By fixing the two ends of the installation column 20 to the installation beam 12 and the bottom wall 13 of the installation space 11 respectively, the installation column 20 can be reliably supported between the installation beam 12 and the bottom wall 13 of the installation space 11, thereby improving the overall structural strength of the energy storage box 100. After the energy storage unit is placed in the energy storage box 100, the risk of deformation of the energy storage box 100 can be reduced, thereby improving the service life of the energy storage box 100.

[0049] In the above technical solution, the two ends of the mounting column 20 are fixedly connected to the mounting beam 12 and the bottom wall 13 of the mounting space 11, respectively, so that the mounting column 20 can be supported between the mounting beam 12 and the bottom wall 13 of the mounting space 11. Since the bottom wall 13 of the mounting space 11 is a plate-like structure, the structural strength of the energy storage box 100 can be improved, thereby reducing the risk of deformation of the energy storage box 100 and further increasing the service life of the energy storage box 100.

[0050] According to some embodiments of the present application, as shown in Figures 3 to 6, the energy storage box 100 may further include: a mounting bracket 30, which is arranged in the installation space 11 and has a limiting portion 31. The limiting portion 31 is assembled with the mounting column 20 to limit the movement of the mounting bracket 30 in the height direction of the energy storage box 100, and the mounting bracket 30 is riveted to the mounting column 20.

[0051] The mounting bracket 30 is used to mount and support the energy storage unit. The mounting bracket 30 is assembled with the mounting post 20 and is fixedly mounted thereto. The mounting bracket 30 has a limiting portion 31. When the limiting portion 31 is assembled with the mounting post 20, the limiting portion 31 is engaged with the mounting post 20. As an example, the limiting portion 31 is inserted into the groove structure or hole structure of the mounting post 20, thereby limiting the movement of the mounting bracket 30 relative to the mounting post 20 in the height direction of the energy storage box 100. The mounting bracket 30 is riveted to the mounting post 20, as an example, the mounting bracket 30 and the mounting post 20 are riveted together using rivets 60.

[0052] It should be noted that the conventional welding connection between the mounting bracket 30 and the mounting post 20 is complex and time-consuming, which affects the assembly efficiency of the energy storage box 100. In the present application, however, the positioning portion 31 is assembled with the mounting post 20, and the mounting bracket 30 and the mounting post 20 are riveted together, eliminating the need for welding the mounting bracket 30 and the mounting post 20. This simplifies the assembly process of the mounting bracket 30 and the mounting post 20, reduces the assembly time of the mounting bracket 30 and the mounting post 20, and improves the assembly efficiency of the energy storage box 100.

[0053] In the above technical solution, the limiting portion 31 is assembled with the mounting column 20, and the mounting frame 30 and the mounting column 20 are riveted together. There is no need to weld the mounting frame 30 and the mounting column 20, which can simplify the assembly process of the mounting frame 30 and the mounting column 20, and can also reduce the assembly time of the mounting frame 30 and the mounting column 20, which can improve the assembly efficiency of the energy storage box 100.

[0054] According to some embodiments of the present application, as shown in FIG. 7 , the mounting post 20 has an inserting hole 32 , and the limiting portion 31 is assembled in the inserting hole 32 and is adapted to abut against an inner wall of the inserting hole 32 .

[0055] Among them, when the mounting bracket 30 and the mounting column 20 are assembled together, the limiting portion 31 is inserted into the plug hole 32, and the limiting portion 31 can abut against the inner wall surface of the plug hole 32 to limit the position, which can limit the movement of the mounting bracket 30 relative to the mounting column 20, so that the mounting bracket 30 and the mounting column 20 can be assembled reliably. Moreover, before the mounting bracket 30 and the mounting column 20 are riveted together, the limiting portion 31 is inserted into the plug hole 32, which can position the mounting bracket 30 relative to the mounting column 20, making it easier for the mounting bracket 30 to be riveted together with the mounting column 20, thereby improving the assembly efficiency of the mounting bracket 30 and the mounting column 20.

[0056] In the above technical solution, by inserting the limiting portion 31 into the plug-in hole 32, the limiting portion 31 can abut against the inner wall surface of the plug-in hole 32 for limiting the position, which can limit the movement of the mounting bracket 30 relative to the mounting column 20, so that the mounting bracket 30 and the mounting column 20 can be assembled reliably. Moreover, before the mounting bracket 30 and the mounting column 20 are riveted together, the limiting portion 31 is inserted into the plug-in hole 32, which can position the mounting bracket 30 relative to the mounting column 20, facilitating the riveting connection between the mounting bracket 30 and the mounting column 20, thereby improving the assembly efficiency of the mounting bracket 30 and the mounting column 20.

[0057] According to some embodiments of the present application, as shown in Figure 7, the mounting frame 30 has a through-hole structure 33, the inner wall of the through-hole structure 33 is connected to a flange structure 34 bent toward the mounting column 20, the flange structure 34 is constructed as a limiting portion 31, and the flange structure 34 is passed through the plug-in hole 32.

[0058] Among them, the mounting frame 30 has a through-hole structure 33, which passes through the mounting frame 30 along the thickness direction of the mounting frame 30. The inner wall of the through-hole structure 33 is connected to a flange structure 34. One end of the flange structure 34 is connected to the inner wall of the through-hole structure 33. The flange structure 34 is bent toward the mounting column 20. The flange structure 34 can be integrally formed with the mounting frame 30. The flange structure 34 is constructed as a limiting portion 31. When the mounting bracket 30 and the mounting column 20 are assembled together, the flange structure 34 is passed through the plug-in hole 32. The flange structure 34 can abut against the inner wall surface of the plug-in hole 32 to limit the movement of the mounting bracket 30 relative to the mounting column 20, so that the mounting bracket 30 and the mounting column 20 can be assembled reliably. Moreover, before the mounting bracket 30 and the mounting column 20 are riveted together, the flange structure 34 is passed through the plug-in hole 32, which can position the mounting bracket 30 relative to the mounting column 20, facilitating the riveting connection between the mounting bracket 30 and the mounting column 20, thereby improving the assembly efficiency of the mounting bracket 30 and the mounting column 20.

[0059] In the above technical solution, by providing the mounting frame 30 with a through-hole structure 33, and connecting the inner wall of the through-hole structure 33 with a flange structure 34 that bends toward the mounting post 20, the arrangement of the limiting portion 31 can be achieved, thereby simplifying the structure of the mounting frame 30. Furthermore, when the mounting frame and the mounting post 20 are assembled, the flange structure 34 is provided through the insertion hole 32, and the flange structure 34 can abut against the inner wall surface of the insertion hole 32 to limit the movement of the mounting frame 30 relative to the mounting post 20, thereby ensuring a reliable assembly of the mounting frame 30 and the mounting post 20. At the same time, before the mounting frame 30 and the mounting post 20 are riveted together, the flange structure 34 is provided through the insertion hole 32 to position the mounting frame 30 relative to the mounting post 20, facilitating the riveted connection between the mounting frame 30 and the mounting post 20, thereby improving the assembly efficiency of the mounting frame 30 and the mounting post 20.

[0060] According to some embodiments of the present application, as shown in FIG. 7 , the mounting post 20 has a first rivet hole, and the mounting bracket 30 has a second rivet hole corresponding to the first rivet hole.

[0061] The mounting post 20 has a first rivet hole, and the mounting bracket 30 has a second rivet hole. The first rivet hole and the second rivet hole are arranged in a corresponding manner. When the mounting bracket 30 and the mounting post 20 are assembled, the first rivet hole and the second rivet hole are arranged opposite each other. The rivet 60 is simultaneously inserted through the first rivet hole and the second rivet hole to rivet the mounting bracket 30 and the mounting post 20, thereby achieving a fixed assembly of the mounting bracket 30 and the mounting post 20.

[0062] In the above technical solution, by setting the first rivet hole and the second rivet hole, when the mounting frame 30 and the mounting column 20 are assembled together, the first rivet hole and the second rivet hole are arranged relative to each other, and the rivet 60 is passed through the first rivet hole and the second rivet hole at the same time to make the mounting frame 30 and the mounting column 20 riveted together, thereby realizing the fixed assembly of the mounting frame 30 and the mounting column 20.

[0063] According to some embodiments of the present application, as shown in FIG7 , a plurality of first rivet holes and a plurality of second rivet holes may be provided, and the plurality of first rivet holes and the plurality of second rivet holes are provided in one-to-one correspondence, and a plurality of rivets 60 respectively and simultaneously pass through the corresponding first rivet holes and the second rivet holes, so that the mounting frame 30 and the mounting column 20 can be firmly assembled, and the assembly reliability of the mounting frame 30 and the mounting column 20 can be improved.

[0064] According to some embodiments of the present application, as shown in Figures 5 and 9, the mounting column 20 includes: a first assembly portion 22, a second assembly portion 23 and a third assembly portion 24, the first assembly portion 22 and the third assembly portion 24 are located on the same side of the second assembly portion 23, the second assembly portion 23 is assembled with the corresponding mounting frame 30, and the first assembly portion 22 and the third assembly portion 24 are assembled with the corresponding mounting frame 30.

[0065] The mounting post 20 may be an integrally formed part. The mounting post 20 may include a first assembly portion 22, a second assembly portion 23, and a third assembly portion 24. Each of the first assembly portion 22, the second assembly portion 23, and the third assembly portion 24 may be a plate-like structure. The second assembly portion 23 may be provided with a first rivet hole and a plug hole 32. At least one of the first assembly portion 22 and the third assembly portion 24 may be provided with a first rivet hole and a plug hole 32. The first assembly portion 22 and the third assembly portion 24 are located on the same side of the second assembly portion 23, and the first assembly portion 22 and the third assembly portion 24 are opposite and spaced apart from each other. The second assembly portion 23 is assembled with a corresponding mounting bracket 30, and the first assembly portion 22 and the third assembly portion 24 are assembled with the corresponding mounting bracket 30. As an example, mounting brackets 30 are provided on opposite sides of a single mounting post 20, with the mounting post 20 positioned between the two mounting brackets 30. The mounting bracket 30 located on the side of the second assembly portion 23 facing away from the first assembly portion 22 is assembled with the second assembly portion 23, while the mounting bracket 30 located on the side of the first assembly portion 22 facing away from the second assembly portion 23 is assembled with the first assembly portion 22 and the third assembly portion 24. By providing the first assembly portion 22, the second assembly portion 23, and the third assembly portion 24, mounting brackets 30 can be installed on opposite sides of a single mounting post 20, enabling the installation of multiple mounting brackets 30 on the same mounting post 20, thereby facilitating the installation of more energy storage units within the energy storage box 100.

[0066] In the above technical solution, by providing the first assembly portion 22, the second assembly portion 23 and the third assembly portion 24, the mounting brackets 30 can be installed on opposite sides of a mounting column 20, so that the same mounting column 20 can be equipped with multiple mounting brackets 30, which is conducive to installing more energy storage units in the energy storage box 100.

[0067] According to some embodiments of the present application, as shown in Figures 5 and 9, the mounting column 20 may further include: a first connecting portion 25 and a second connecting portion 26, the first connecting portion 25 being connected between the first assembly portion 22 and the second assembly portion 23, and the second connecting portion 26 being connected between the second assembly portion 23 and the third assembly portion 24.

[0068] The mounting post 20 may further include a first connecting portion 25 and a second connecting portion 26. Both the first connecting portion 25 and the second connecting portion 26 may be plate-shaped structures. The first connecting portion 25 has opposing first and second sides along the arrangement direction of the first and second mounting portions 22, 23. The first side of the first connecting portion 25 is connected to the first mounting portion 22, and the second side of the first connecting portion 25 is connected to the second mounting portion 23. The second connecting portion 26 has opposing third and fourth sides. The third side of the second connecting portion 26 is connected to the second mounting portion 23, and the fourth side of the second connecting portion 26 is connected to the third mounting portion 24. This spaced the first and second mounting portions 22, 23 apart along the arrangement direction of the first and second mounting portions 22, 23, and also spaced the second and third mounting portions 23, 24 apart along the arrangement direction of the first and second mounting portions 22, 23. In a direction perpendicular to the arrangement direction of the first and second mounting portions 22, 23, the first and third mounting portions 24 are opposed to and spaced apart. By providing the first connecting portion 25 and the second connecting portion 26, the first connecting portion 25 is connected between the first assembly portion 22 and the second assembly portion 23, and the second connecting portion 26 is connected between the second assembly portion 23 and the third assembly portion 24, which is conducive to the installation column 20 forming a "J"-shaped structure, or the installation column 20 forming a structure similar to the "J"-shaped structure, which is conducive to improving the structural strength of the installation column 20. When multiple mounting brackets 30 are simultaneously assembled on the same installation column 20, the risk of deformation of the installation column 20 is reduced, so that the installation column 20 is reliably supported between the mounting beam 12 and the bottom wall 13 of the installation space 11, which is more conducive to improving the structural strength of the energy storage box 100.

[0069] In the above technical solution, by providing the first connecting portion 25 and the second connecting portion 26, the first connecting portion 25 is connected between the first assembly portion 22 and the second assembly portion 23, and the second connecting portion 26 is connected between the second assembly portion 23 and the third assembly portion 24, which is conducive to the installation column 20 forming a "J"-shaped structure, or the installation column 20 forming a structure similar to the "J"-shaped structure, which is conducive to improving the structural strength of the installation column 20. When multiple mounting frames 30 are simultaneously assembled on the same installation column 20, the risk of deformation of the installation column 20 is reduced, so that the installation column 20 is reliably supported between the installation beam 12 and the bottom wall 13 of the installation space 11, which is more conducive to improving the structural strength of the energy storage box 100.

[0070] According to some embodiments of the present application, as shown in FIG. 5 and FIG. 9 , the first connection portion 25 and the second connection portion 26 are parallel.

[0071] Among them, the first connecting part 25 and the second connecting part 26 can both be plate-like structures. The first connecting part 25 and the second connecting part 26 are arranged oppositely and spaced apart in a direction perpendicular to the arrangement direction of the first assembly part 22 and the second assembly part 23. The first connecting part 25 and the second connecting part 26 are parallel to each other, which can enable the mounting column 20 to form a "J"-shaped structure, which is more conducive to improving the structural strength of the mounting column 20. When multiple mounting frames 30 are simultaneously assembled on the same mounting column 20, the risk of deformation of the mounting column 20 is further reduced, so that the mounting column 20 can be reliably supported between the mounting beam 12 and the bottom wall 13 of the mounting space 11, which is more conducive to improving the structural strength of the energy storage box 100.

[0072] In the above technical solution, by arranging the first connecting portion 25 and the second connecting portion 26 in parallel, the mounting column 20 can be formed into a "J"-shaped structure, which is more conducive to improving the structural strength of the mounting column 20. When multiple mounting frames 30 are simultaneously assembled on the same mounting column 20, the risk of deformation of the mounting column 20 is further reduced, so that the mounting column 20 is reliably supported between the mounting beam 12 and the bottom wall 13 of the mounting space 11, which is more conducive to improving the structural strength of the energy storage box 100.

[0074] As shown in Figure 4 , when the energy storage box 100 is positioned in the orientation shown in Figure 4 , the X direction in Figure 4 is the first direction. Multiple mounting beams 12 are provided, and the number of mounting beams 12 can be two, three, four, or the like. The multiple mounting beams 12 are sequentially spaced apart along the first direction. The multiple mounting beams 12 can be parallel to each other, and the spacing between adjacent mounting beams 12 along the first direction is the same. A mounting post 20 is connected between each mounting beam 12 and the bottom wall 13. By providing multiple mounting beams 12, and each mounting post 20 is connected between each mounting beam 12 and the bottom wall 13, more mounting racks 30 can be installed within the installation space 11 of the energy storage box 100, thereby allowing for the simultaneous placement of more energy storage units within the energy storage box 100, thereby facilitating the improvement of the energy density of the energy storage box 100. Furthermore, the number of mounting columns 20 can be increased, so that multiple mounting columns 20 can be simultaneously supported between the corresponding mounting beams 12 and the bottom wall 13 of the mounting space 11, which can further improve the structural strength of the energy storage box 100, thereby further reducing the risk of deformation of the energy storage box 100, and further improving the service life of the energy storage box 100.

[0075] In the above technical solution, by providing multiple mounting beams 12, with mounting posts 20 connected between each mounting beam 12 and the bottom wall 13, more mounting racks 30 can be installed within the installation space 11 of the energy storage box 100, thereby allowing more energy storage units to be placed simultaneously within the energy storage box 100, thereby facilitating an increase in the energy density of the energy storage box 100. Furthermore, the number of mounting posts 20 can be increased, allowing multiple mounting posts 20 to be simultaneously supported between corresponding mounting beams 12 and the bottom wall 13 of the installation space 11, further enhancing the structural strength of the energy storage box 100, thereby further reducing the risk of deformation of the energy storage box 100 and further increasing the service life of the energy storage box 100.

[0077] As shown in Figure 4 , when the energy storage box 100 is positioned in the orientation shown in Figure 4 , the Y direction in Figure 4 is the second direction. Multiple mounting posts 20 are connected between each mounting beam 12 and the bottom wall 13.

The multiple mounting posts 20 may be parallel to each other, and the spacing between adjacent two mounting posts 20 along the second direction is the same. By connecting multiple mounting posts 20 between each mounting beam 12 and the bottom wall 13, and by sequentially arranging the multiple mounting posts 20 along the second direction, the mounting frame 30 can be fixedly assembled with the multiple mounting posts 20 at the same time. The multiple mounting posts 20 can support one mounting frame 30 at the same time, thereby improving the position stability of the mounting frame 30. In addition, the number of mounting posts 20 can be further increased, so that more mounting posts 20 can be simultaneously supported between the corresponding mounting beams 12 and the bottom wall 13 of the installation space 11, which can further improve the structural strength of the energy storage box 100, thereby further reducing the risk of deformation of the energy storage box 100, and further improving the service life of the energy storage box 100.

[0078] In the above technical solution, multiple mounting posts 20 are connected between each mounting beam 12 and the bottom wall 13, and the multiple mounting posts 20 are arranged sequentially along the second direction. Therefore, the mounting frame 30 can be fixedly assembled with the multiple mounting posts 20 at the same time. The multiple mounting posts 20 can support one mounting frame 30 at the same time, thereby improving the position stability of the mounting frame 30. In addition, the number of mounting posts 20 can be further increased, so that more mounting posts 20 can be supported simultaneously between the corresponding mounting beams 12 and the bottom wall 13 of the installation space 11, which can further improve the structural strength of the energy storage box 100, thereby further reducing the risk of deformation of the energy storage box 100, and further improving the service life of the energy storage box 100.

[0079] According to some embodiments of the present application, as shown in FIG8 , the bottom wall 13 of the installation space 11 has a drainage hole 14 , and a drainage valve 15 is provided in the drainage hole 14 .

[0080] The bottom wall 13 of the installation space 11 is provided with a drainage hole 14, which extends through the bottom wall 13 of the installation space 11 along its thickness. A drainage valve 15 may be provided within the drainage hole 14. As an example, multiple drainage holes 14 and multiple drainage valves 15 may be provided, with each drainage hole 14 and each drainage valve 15 corresponding to each other, i.e., each drainage hole 14 is provided with a drainage valve 15. By providing the drainage holes 14 and drainage valve 15, when liquid accumulates on the bottom wall 13 of the installation space 11 of the energy storage box 100, the liquid can be discharged from the energy storage box 100 through the drainage valve 15, thereby reducing the risk of liquid accumulation within the installation space 11 of the energy storage box 100, the risk of short-circuiting the energy storage units within the energy storage box 100 due to the accumulated liquid, and the risk of electric shock to users.

[0081] In the above technical solution, by providing the drain hole 14 and the drain valve 15, when liquid in the installation space 11 of the energy storage box 100 accumulates on the bottom wall 13 of the installation space 11, the liquid can be discharged from the energy storage box 100 through the drain valve 15, thereby reducing the risk of liquid accumulation in the installation space 11 of the energy storage box 100, reducing the risk of short circuit of the energy storage unit in the energy storage box 100 caused by the accumulated liquid, and also reducing the risk of electric shock to the user.

[0082] According to some embodiments of the present application, as shown in FIG8 , the drain valve 15 can be configured as a one-way valve. By configuring the drain valve 15 as a pilot valve, when liquid within the installation space 11 of the energy storage box 100 accumulates on the bottom wall 13 of the installation space 11, the liquid can be discharged from the energy storage box 100 through the drain valve 15, thereby reducing the risk of liquid accumulation within the installation space 11 of the energy storage box 100. Furthermore, objects outside the energy storage box 100 cannot flow through the pilot valve into the installation space 11 of the energy storage box 100, thereby improving the cleanliness of the installation space 11 of the energy storage box 100.

[0083] In the above technical solution, by configuring the drain valve 15 as a pilot valve, when liquid in the installation space 11 of the energy storage box 100 accumulates on the bottom wall 13 of the installation space 11, the liquid can be discharged from the energy storage box 100 through the drain valve 15, thereby reducing the risk of liquid accumulation in the installation space 11 of the energy storage box 100. In addition, objects outside the energy storage box 100 cannot flow into the installation space 11 of the energy storage box 100 through the pilot valve, thereby improving the cleanliness of the installation space 11 of the energy storage box 100.

[0084] According to some embodiments of the present application, as shown in FIG8 , a diversion slope 16 is formed on the inner surface of the bottom wall 13 . The diversion slope 16 is disposed adjacent to the drainage hole 14 and is suitable for diverting liquid to the drainage hole 14 .

[0085] The inner surface of the bottom wall 13 may be formed with a diverter slope 16, that is, the upper surface of the bottom wall 13 of the installation space 11 may be formed with a diverter slope 16. Multiple diverter slopes 16 may be provided, each disposed adjacent to a corresponding drainage hole 14. The diverter slopes 16 are adapted to guide liquid to the corresponding drainage hole 14. When liquid within the installation space 11 of the energy storage box 100 accumulates on the bottom wall 13 of the installation space 11, the diverter slopes 16 facilitate the liquid's flow along the diverter slopes 16 toward the corresponding drainage hole 14, thereby facilitating the liquid's discharge from the installation space 11 of the energy storage box 100 and enabling rapid drainage of the liquid within the installation space 11 of the energy storage box 100.

[0086] In the above technical solution, by providing the guiding slope 16, when liquid in the installation space 11 of the energy storage box 100 accumulates on the bottom wall 13 of the installation space 11, the guiding effect of the guiding slope 16 facilitates the liquid to flow along the guiding slope 16 to the corresponding drainage hole 14, thereby facilitating the liquid in the installation space 11 of the energy storage box 100 to be discharged from the energy storage box 100, thereby enabling the liquid in the installation space 11 of the energy storage box 100 to be quickly discharged.

[0087] According to some embodiments of the present application, as shown in FIG. 8 , the guiding slope 16 is disposed around the drainage hole 14 .

[0088] The guiding slope 16 may be arc-shaped or annular, and is disposed along the circumferential edge of the drainage hole 14 and around the drainage hole 14. By disposing the guiding slope 16 around the drainage hole 14, when liquid in the installation space 11 of the energy storage box 100 accumulates on the bottom wall 13 of the installation space 11, the guiding effect of the guiding slope 16 facilitates the liquid to flow along the guiding slope 16 toward the corresponding drainage hole 14, thereby facilitating the liquid in the installation space 11 of the energy storage box 100 to drain out of the energy storage box 100, thereby enabling the liquid in the installation space 11 of the energy storage box 100 to be drained more quickly.

[0089] In the above technical solution, the guiding slope 16 is arranged around the drainage hole 14. When liquid in the installation space 11 of the energy storage box 100 accumulates on the bottom wall 13 of the installation space 11, the guiding effect of the guiding slope 16 is more conducive to the liquid flowing along the guiding slope 16 to the corresponding drainage hole 14, thereby further facilitating the liquid in the installation space 11 of the energy storage box 100 to be discharged from the energy storage box 100, thereby enabling the liquid in the installation space 11 of the energy storage box 100 to be discharged more quickly.

The electrical components inside the energy storage box 100 are connected to the exterior of the energy storage box 100 via wiring harnesses. There may be multiple wiring harnesses, each of which can be passed through the wiring holes 17. After the wiring harnesses pass through the corresponding wiring holes 17 and the corresponding cover plates 40, the cover plates 40 are placed over the corresponding wiring holes 17 to seal the wiring holes 17. This reduces the risk of external objects entering the energy storage box 100 through the wiring holes 17. Furthermore, the provision of multiple wiring holes 17 facilitates the installation of the cover plates 40 after the wiring harnesses pass through the corresponding wiring holes 17, thereby improving the assembly efficiency of the energy storage box 100.

[0092] In the above technical solution, by providing multiple cover plates 40 and multiple wiring holes 17, multiple wiring harnesses can be respectively passed through the multiple wiring holes 17. After the wiring harness passes through the corresponding wiring hole 17 and the corresponding cover plate 40, the cover plate 40 is covered on the corresponding wiring hole 17 to close the wiring hole 17, thereby reducing the risk of external objects from the energy storage box 100 entering the energy storage box 100 through the wiring hole 17. In addition, by providing multiple wiring holes 17, after the wiring harness passes through the corresponding wiring hole 17, it is convenient to install the cover plate 40 after threading the wires, thereby improving the assembly efficiency of the energy storage box 100.
