Installation columns are provided in the box body of the energy storage box, and the energy storage units are installed on the mounting frames of the installation columns. However, the existing energy storage box has poor structural strength. After the energy storage units are installed on the mounting frames, it is easy to cause the energy storage box to deform, affecting the service life of the energy storage box. Summary of the Invention

[0003] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, an object of the present application is to provide an energy storage box. The installation column of the energy storage box is supported between the installation beam and the bottom wall of the installation space, which can improve the structural strength of the energy storage box, thereby reducing the risk of deformation of the energy storage box, and further improving the service life of the energy storage box.

[0004] The present application further provides an energy storage device.

[0005] In a first aspect, an embodiment of the present application provides an energy storage box, including:

[0006] A box body that defines an installation space. An installation beam is provided in the installation space and is located at the top of the installation space. The installation beam is fixed to the box body. The bottom wall of the installation space and the installation beam are opposite and spaced apart in the height direction of the energy storage box. The bottom wall of the installation space is a plate-like structure;

[0007] Installation columns are disposed in the installation space, and both ends of the installation columns are fixedly connected to the installation beam and the bottom wall of the installation space respectively.

[0008] In the above technical solution, by fixedly connecting both ends of the installation column to the installation beam and the bottom wall of the installation space respectively, the installation column can be supported between the installation beam and the bottom wall of the installation space. Since the bottom wall of the installation space is a plate-like structure, the structural strength of the energy storage box can be improved, thereby reducing the risk of deformation of the energy storage box, and further improving the service life of the energy storage box.

[0009] In some embodiments, the energy storage box further includes: a mounting frame disposed in the installation space and having a limiting portion. The limiting portion is cooperatively assembled with the installation column to limit the movement of the mounting frame in the height direction of the energy storage box, and the mounting frame is riveted to the installation column.

[0010] In the above technical solution, by fitting and assembling the limiting part with the mounting column, and riveting the mounting frame to the mounting column, welding of the mounting frame and the mounting column is not required, which can simplify the assembly process of the mounting frame and the mounting column, reduce the assembly time of the mounting frame and the mounting column, and improve the assembly efficiency of the energy storage box.

[0011] In some embodiments, the mounting column has a plug hole, and the limiting part is assembled in the plug hole and is adapted to abut against the inner wall of the plug hole.

[0012] In the above technical solution, by inserting the limiting part into the plug hole, the limiting part can abut against and limit the inner wall surface of the plug hole, which can restrict the movement of the mounting frame relative to the mounting column, so that the assembly of the mounting frame and the mounting column can be reliable. Moreover, before the mounting frame and the mounting column are riveted together, inserting the limiting part into the plug hole can position the mounting frame relative to the mounting column, facilitating the riveting connection between the mounting frame and the mounting column, thereby improving the assembly efficiency of the mounting frame and the mounting column.

[0013] In some embodiments, the mounting frame has a through-hole structure, and a flanging structure bent towards the mounting column is connected to the inner wall of the through-hole structure. The flanging structure is configured as the limiting part, and the flanging structure passes through the plug hole.

[0014] In the above technical solution, by providing a through-hole structure on the mounting frame and connecting a flanging structure bent towards the mounting column to the inner wall of the through-hole structure, the arrangement of the limiting part can be realized, and the structure of the mounting frame can be simplified. When the mounting frame and the mounting column are assembled, the flanging structure passes through the plug hole, and the flanging structure can abut against and limit the inner wall surface of the plug hole, which can restrict the movement of the mounting frame relative to the mounting column, so that the assembly of the mounting frame and the mounting column can be reliable. At the same time, before the mounting frame and the mounting column are riveted together, the flanging structure passes through the plug hole, which can position the mounting frame relative to the mounting column, facilitating the riveting connection between the mounting frame and the mounting column, thereby improving the assembly efficiency of the mounting frame and the mounting column.

[0015] In some embodiments, the mounting column has a first riveting hole, and the mounting frame has a second riveting hole corresponding to the first riveting hole.

[0016] In the above technical solution, by providing the first riveting hole and the second riveting hole, when the mounting frame and the mounting column are assembled, the first riveting hole and the second riveting hole are arranged opposite to each other, and the mounting frame and the mounting column are riveted together by passing a rivet through the first riveting hole and the second riveting hole at the same time, thereby realizing the fixed assembly of the mounting frame and the mounting column.

[0017] In some embodiments, the mounting column includes: a first assembly part, a second assembly part, and a third assembly part. The first assembly part and the third assembly part are on the same side of the second assembly part. The second assembly part is assembled with the corresponding mounting frame, and the first assembly part and the third assembly part are assembled with the corresponding mounting frame.

[0018] In the above technical solution, by providing the first assembly part, the second assembly part, and the third assembly part, mounting brackets can be mounted on opposite sides of a mounting post, achieving the effect of assembling multiple mounting brackets on the same mounting post, which is conducive to installing more energy storage units in the energy storage box.

[0019] In some embodiments, the mounting post further includes: a first connecting part and a second connecting part. The first connecting part is connected between the first assembly part and the second assembly part, and the second connecting part is connected between the second assembly part and the third assembly part.

[0020] In the above technical solution, by providing the first connecting part and the second connecting part, with the first connecting part connected between the first assembly part and the second assembly part and the second connecting part connected between the second assembly part and the third assembly part, it is conducive to the mounting post forming a "ji" - shaped structure, or a structure similar to a "ji" - shaped structure, which is beneficial to enhancing the structural strength of the mounting post. When multiple mounting brackets are assembled on the same mounting post simultaneously, the risk of deformation of the mounting post is reduced, enabling the mounting post to be reliably supported between the mounting beam and the bottom wall of the installation space, which is more conducive to enhancing the structural strength of the energy storage box.

[0021] In some embodiments, the first connecting part and the second connecting part are parallel.

[0022] In the above technical solution, by arranging the first connecting part and the second connecting part in parallel, the mounting post can form a "ji" - shaped structure, which is more beneficial to enhancing the structural strength of the mounting post. When multiple mounting brackets are assembled on the same mounting post simultaneously, the risk of deformation of the mounting post is further reduced, enabling the mounting post to be reliably supported between the mounting beam and the bottom wall of the installation space, which is more conducive to enhancing the structural strength of the energy storage box.

[0023] In some embodiments, there are multiple mounting beams, and the multiple mounting beams are arranged in sequence along a first direction. A mounting post is connected between each mounting beam and the bottom wall, and the first direction is perpendicular to the height direction of the energy storage box.

[0024] In the above technical solution, by providing multiple mounting beams and connecting a mounting post between each mounting beam and the bottom wall, more mounting brackets can be arranged in the installation space of the energy storage box, so that more energy storage units can be placed in the energy storage box simultaneously, which is conducive to enhancing the energy density of the energy storage box. Moreover, the number of mounting posts can be increased, enabling multiple mounting posts to support between the corresponding mounting beam and the bottom wall of the installation space simultaneously, which can further enhance the structural strength of the energy storage box, thereby further reducing the risk of deformation of the energy storage box and further enhancing the service life of the energy storage box.

[0025] In some embodiments, a plurality of mounting columns are connected between each mounting beam and the bottom wall, and the plurality of mounting columns are arranged in sequence along the second direction, and the first direction, the second direction and the height direction of the energy storage box are perpendicular to each other.

[0026] In the above technical solution, by connecting a plurality of mounting columns between each mounting beam and the bottom wall, and arranging the plurality of mounting columns in sequence along the second direction, the mounting frame can be fixedly assembled with a plurality of mounting columns at the same time. A plurality of mounting columns can support one mounting frame at the same time, thereby improving the position stability of the mounting frame. Moreover, the number of mounting columns can be further increased, so that more mounting columns can support between the corresponding mounting beam and the bottom wall of the mounting space at the same time, which can further improve the structural strength of the energy storage box, thereby further reducing the risk of deformation of the energy storage box, and further improving the service life of the energy storage box.

[0027] In some embodiments, the bottom wall of the mounting space has a drain hole, and a drain valve is provided in the drain hole.

[0028] In the above technical solution, by providing the drain hole and the drain valve, when the liquid in the mounting space of the energy storage box accumulates on the bottom wall of the mounting space, the liquid can be discharged from the drain valve out of the energy storage box, reducing the risk of liquid accumulation in the mounting space of the energy storage box, reducing the risk of short circuit of the energy storage unit in the energy storage box caused by the accumulated liquid, and also reducing the risk of electric shock to the user.

[0029] In some embodiments, the drain valve is configured as a check valve.

[0030] In the above technical solution, by setting the drain valve as a check valve, when the liquid in the mounting space of the energy storage box accumulates on the bottom wall of the mounting space, the liquid can be discharged from the drain valve out of the energy storage box, reducing the risk of liquid accumulation in the mounting space of the energy storage box. In addition, objects outside the energy storage box cannot flow into the mounting space of the energy storage box through the check valve, which can improve the cleanliness of the mounting space of the energy storage box.

[0031] In some embodiments, a guiding inclined surface is formed on the inner surface of the bottom wall, the guiding inclined surface is adjacently arranged with the drain hole, and the guiding inclined surface is adapted to guide the liquid to the drain hole.

[0032] In the above technical solution, by providing the guiding inclined surface, when the liquid in the mounting space of the energy storage box accumulates on the bottom wall of the mounting space, under the guiding action of the guiding inclined surface, it is beneficial for the liquid to flow along the guiding inclined surface to the corresponding drain hole, thereby facilitating the discharge of the liquid in the mounting space of the energy storage box out of the energy storage box, and further enabling the liquid in the mounting space of the energy storage box to be quickly discharged.

[0033] In some embodiments, the guiding inclined surface is arranged around the drain hole.

[0034] In the above technical solution, by arranging the diversion inclined plane around the liquid discharge hole, when liquid accumulates on the bottom wall of the installation space of the energy storage box, under the diversion effect of the diversion inclined plane, it is more conducive to the liquid flowing along the diversion inclined plane towards the corresponding liquid discharge hole, thereby making it more conducive to the liquid in the installation space of the energy storage box to be discharged from the energy storage box, and further enabling the liquid in the installation space of the energy storage box to be discharged more quickly.

[0035] In some embodiments, the energy storage box further includes: a plurality of cover plates, the bottom wall of the installation space has a plurality of wire routing holes, and the plurality of cover plates are respectively adapted to cover the plurality of wire routing holes.

[0036] In the above technical solution, by providing a plurality of cover plates and a plurality of wire routing holes, a plurality of wire harnesses can respectively pass through the plurality of wire routing holes. After the wire harness passes through the corresponding wire routing hole and the corresponding cover plate, the cover plate is covered on the corresponding wire routing hole to close the wire routing hole, reducing the risk of external objects of the energy storage box entering the energy storage box through the wire routing hole. Moreover, by providing a plurality of wire routing holes, after the wire harness passes through the corresponding wire routing hole, it is conducive to the installation of the cover plate after threading, thereby improving the assembly efficiency of the energy storage box.

[0037] In some embodiments, the box body further defines an electrical compartment, and the electrical compartment is located at the end of the energy storage box.

[0038] In the above technical solution, by arranging the electrical compartment at the end of the energy storage box, when an electrical component in the electrical compartment fails, it is convenient to repair the electrical component in the electrical compartment on site, thereby facilitating the on-site maintenance of the energy storage box.

[0074] The development of battery technology needs to consider multiple design factors at the same time. For example, performance parameters such as energy density, cycle life, discharge capacity, charge and discharge rate, etc. In addition, the safety performance of the battery also needs to be considered.

[0075] In an energy storage device, the energy storage box serves as the outer shell of the energy storage device to protect the energy storage unit. The energy storage unit is arranged inside the energy storage box. There are mounting posts in the box body of the energy storage box, and the energy storage unit is mounted on the mounting frame of the mounting post. The existing energy storage box has poor structural strength. After the energy storage unit is mounted on the mounting frame, under the action of the gravity of the energy storage unit, the energy storage box is likely to be deformed, affecting the service life of the energy storage box.

[0076] In view of this, the embodiments of the present application provide an energy storage box. The energy storage box includes a box body and mounting posts. The box body defines a mounting space. There is a mounting beam in the mounting space. The mounting beam is fixed to the box body. The bottom wall of the mounting space is a plate-like structure. The mounting posts are arranged in the mounting space, and both ends of the mounting posts are fixedly connected to the mounting beam and the bottom wall of the mounting space respectively.

[0077] In such an energy storage box, by setting the bottom wall of the mounting space as a plate-like structure and fixedly connecting both ends of the mounting posts to the mounting beam and the bottom wall of the mounting 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 thus the service life of the energy storage box can be improved.

[0078] Next, refer to Figures 1-9Describe the energy storage box 100 according to the embodiments of the present application. The energy storage device includes an energy storage unit and the energy storage box 100, and the energy storage unit is installed inside the energy storage box 100.

[0079] The energy storage box 100 according to the embodiments of the present application includes: a box body 10 and a mounting post 20. The box body 10 defines an installation space 11, and an installation beam 12 is provided inside the installation space 11 and is located at the top of the installation space 11. The installation beam 12 is fixed to the box body 10. The bottom wall 13 of the installation space 11 and the installation beam 12 are opposite and spaced apart along the height direction of the energy storage box 100. The bottom wall 13 of the installation space 11 is a plate-like structure. The mounting post 20 is provided inside the installation space 11, and both ends of the mounting post 20 are fixedly connected to the installation beam 12 and the bottom wall 13 of the installation space 11 respectively.

[0080] Among them, as Figure 3 shown, the box body 10 defines an installation space 11, and an installation beam 12 is provided inside the installation space 11. Along the up and down direction of the energy storage box 100, that is, along the Figure 3 Z direction in

[0081] In the present application, by constructing 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 support strength of the bottom wall 13 of the installation space 11 can be improved. By fixedly connecting both ends of the mounting post 20 to the installation beam 12 and the bottom wall 13 of the installation space 11 respectively, the mounting post 20 can be reliably supported between the installation beam 12 and the bottom wall 13 of the installation space 11, and the overall structural strength of the energy storage box 100 can be improved. After the energy storage unit is placed inside the energy storage box 100, the risk of deformation of the energy storage box 100 can be reduced, and thus the service life of the energy storage box 100 can be improved.

[0082] In the above technical solution, by fixedly connecting both ends of the mounting column 20 to the mounting beam 12 and the bottom wall 13 of the mounting space 11 respectively, 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.

[0083] According to some embodiments of the present application, as Figures 3-6 shown, the energy storage box 100 may further include: a mounting frame 30, the mounting frame 30 is disposed in the mounting space 11 and has a limiting portion 31, the limiting portion 31 is cooperatively assembled with the mounting column 20 to limit the movement of the mounting frame 30 in the height direction of the energy storage box 100, and the mounting frame 30 is riveted to the mounting column 20.

[0084] Among them, the mounting frame 30 is used to mount the energy storage unit, and the mounting frame 30 can support the energy storage unit. The mounting frame 30 is cooperatively assembled with the mounting column 20, the mounting frame 30 is fixedly installed on the mounting column 20, the mounting frame 30 has a limiting portion 31, when the limiting portion 31 is cooperatively assembled with the mounting column 20, through the limiting cooperation between the limiting portion 31 and the mounting column 20, as an example, the limiting portion 31 is inserted into a groove structure or a hole structure of the mounting column 20, which can limit the relative movement of the mounting frame 30 with respect to the mounting column 20 in the height direction of the energy storage box 100, and moreover, the mounting frame 30 is riveted to the mounting column 20, as an example, the mounting frame 30 and the mounting column 20 are riveted by a rivet 60.

[0085] It should be noted that in the prior art, the mounting frame 30 and the mounting column 20 are welded together, the welding process is complex, time-consuming, and affects the assembly efficiency of the energy storage box 100. In the present application, through the cooperative assembly of the limiting portion 31 and the mounting column 20 and the riveting connection between the mounting frame 30 and the mounting column 20, welding of the mounting frame 30 and the mounting column 20 is not required, which can simplify the assembly process of the mounting frame 30 and the mounting column 20, and also reduce the assembly time of the mounting frame 30 and the mounting column 20, and can improve the assembly efficiency of the energy storage box 100.

[0086] In the above technical solution, through the cooperative assembly of the limiting portion 31 and the mounting column 20 and the riveting connection between the mounting frame 30 and the mounting column 20, welding of the mounting frame 30 and the mounting column 20 is not required, which can simplify the assembly process of the mounting frame 30 and the mounting column 20, and also reduce the assembly time of the mounting frame 30 and the mounting column 20, and can improve the assembly efficiency of the energy storage box 100.

[0087] According to some embodiments of the present application, as Figure 7 shown, the mounting column 20 has a socket hole 32, and the limiting portion 31 is assembled in the socket hole 32 and is adapted to abut against the inner wall of the socket hole 32.

[0088] Among them, when the mounting bracket 30 is assembled with the mounting column 20, the limiting portion 31 is inserted into the insertion hole 32. The limiting portion 31 can abut against and limit the inner wall surface of the insertion hole 32, which can limit the movement of the mounting bracket 30 relative to the mounting column 20. Thus, 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 insertion 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, and thus improving the assembly efficiency of the mounting bracket 30 and the mounting column 20.

[0089] In the above technical solution, by inserting the limiting portion 31 into the insertion hole 32, the limiting portion 31 can abut against and limit the inner wall surface of the insertion hole 32, which can limit the movement of the mounting bracket 30 relative to the mounting column 20. Thus, 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 insertion 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, and thus improving the assembly efficiency of the mounting bracket 30 and the mounting column 20.

[0090] According to some embodiments of the present application, as Figure 7 shown, the mounting bracket 30 has a through-hole structure 33. A flanging structure 34 that bends towards the mounting column 20 is connected to the inner wall of the through-hole structure 33. The flanging structure 34 is configured as the limiting portion 31, and the flanging structure 34 passes through the insertion hole 32.

[0091] Among them, the mounting bracket 30 has a through-hole structure 33. The through-hole structure 33 penetrates through the mounting bracket 30 along the thickness direction of the mounting bracket 30. A flanging structure 34 is connected to the inner wall of the through-hole structure 33. One end of the flanging structure 34 is connected to the inner wall of the through-hole structure 33. The flanging structure 34 bends towards the mounting column 20, and the flanging structure 34 can be integrally formed with the mounting bracket 30. The flanging structure 34 is configured as the limiting portion 31. When the mounting bracket 30 is assembled with the mounting column 20, the flanging structure 34 passes through the insertion hole 32. The flanging structure 34 can abut against and limit the inner wall surface of the insertion hole 32, which can limit the movement of the mounting bracket 30 relative to the mounting column 20. Thus, 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 flanging structure 34 passes through the insertion 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, and thus improving the assembly efficiency of the mounting bracket 30 and the mounting column 20.

[0092] In the above technical solution, since the mounting bracket 30 is provided with a through-hole structure 33 and the inner wall of the through-hole structure 33 is connected with a flanging structure 34 bent towards the mounting post 20, the arrangement of the limiting portion 31 can be realized, and the structure of the mounting bracket 30 can be simplified.
