[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs. The terms used in this specification in the description of the present application are only for the purpose of describing specific embodiments and are not used to limit the present application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0027] The present application provides an energy storage device. The energy storage device includes structures such as a cabinet 1000 and an energy storage module (not shown in the figure). The energy storage module is installed in the cabinet 1000 and is used for storing electric energy.

[0028] For the aforementioned cabinet 1000, in some embodiments, see Figure 1 and Figure 2 The cabinet 1000 includes a cabinet body 100 and a hanging assembly 200, and the cabinet body 100 and the hanging assembly 200 are connected.

[0029] In some embodiments, the cabinet 100 includes a first plate 110, an upper frame 120, and a column 130. The first plate 110 is provided with a through hole 111 that passes through along a preset direction F. Along the preset direction F, the upper frame 120 is provided on one side of the first plate 110, the column 130 is provided on a side of the upper frame 120 that is away from the first plate 110, and the column 130 is connected to the upper frame 120.

[0030] In some embodiments, the cabinet 100 includes a lower frame 180, and along a preset direction F, the column 130 is located between the upper frame 120 and the lower frame 180 and connects the upper frame 120 and the lower frame 180. In some embodiments, the hanging assembly 200 includes a load-bearing member 210 and a hanging ring 220, and the load-bearing member 210 includes a load-bearing seat 211 and a connecting member 212. Along the preset direction F, at least a portion of the load-bearing seat 211 is located between the first plate 110 and the column 130, the load-bearing seat 211 is fixed to the column 130, the connecting member 212 is fixed to the load-bearing seat 211, the connecting member 212 is penetrated through the through hole 111 and connected to the hanging ring 220, and along the preset direction F, the hanging ring 220 is located on the side of the first plate 110 away from the column 130.

[0031] In combination with the above embodiment, the two sides of the connecting member 212 connect the load-bearing seat 211 with the lifting ring 220, and the load-bearing seat 211 is fixed to the column 130, so that the tension exerted on the lifting ring 220 can be transmitted along the connecting member 212, the load-bearing seat 211, the column 130 and the upper frame 120, which is beneficial to alleviate the tension exerted on structures such as the lifting ring 220, the first plate 110 and the load-bearing member 210, and is beneficial to improve the force-bearing capacity of the cabinet 1000 and reduce the phenomenon of damage to the cabinet 1000 during lifting.

[0032] On the one hand, compared with the currently common hollow "C"-shaped beam structure, setting the load-bearing seat 211 as a solid block structure is conducive to improving the structural strength of the load-bearing seat 211; on the other hand, in order to achieve the required connection strength and load-bearing capacity of the "C"-shaped beam structure, it is necessary to connect the "C"-shaped section to the surface of the cabinet 100, and other structures cannot be set in the hollow area in the "C"-shaped section, resulting in an increase in the internal volume occupied by the beam. The load-bearing member 210 in the present application improves the connection strength through the block structure of the load-bearing seat 211 itself, and improves the load-bearing capacity by increasing the contact area.

[0033] In some embodiments, the cabinet 1000 is a hexahedron. The cabinet body 100 includes a first plate 110, a second plate 140, a third plate 150, a fourth plate 160, and a fifth plate 170. The cabinet body 100 formed by these plates is enclosed by at least five sides to form a receiving cavity for receiving the aforementioned energy storage module, and at least one side is provided with a structure that can communicate the receiving cavity with the external environment.

[0034] It should still be noted that the upper rack body 120 and the lower rack body 180 are fixed by the columns 130, so that the upper rack body 120, the columns 130, and the lower rack body 180 together form a frame structure for load-bearing. The upper rack body 120 and the lower rack body 180 serve as the installation base of the cabinet 1000, thereby facilitating the fixation of the aforementioned energy storage module and other functional modules of the energy storage device.

[0035] It should still be noted that the upper rack body 120 and the lower rack body 180 are arranged in a rectangle. In some embodiments, the load-bearing capacity can also be improved by providing structures such as load-bearing beams, force-dividing beams, or reinforcing ribs on the upper rack body 120 and / or the lower rack body 180.

[0036] In some embodiments, please refer to Figures 3 to 5 , the column 130 has a hollow structure. One end of the column 130 is provided with a first mounting hole 121, the upper rack body 120 is provided with a second mounting hole 121, and the surface of the bearing seat 211 facing away from the connecting member 212 is provided with a first screw hole 2111. The hoisting assembly 200 (refer to Figure 1 ) includes a bolt 230. The bolt 230 is located inside the column 130, and the screw rod of the bolt 230 sequentially passes through the first mounting hole 121 and the second mounting hole 121 and is screwed into the first screw hole 2111 to fix the bearing seat 211 to the column 130.

[0037] Among them, the hollow structure of the column 130 means that the main body of the column 130 is hollow inside. Thus, while ensuring its own force transmission ability and load-bearing capacity, the weight of the material inside the column 130 is reduced, and it is beneficial to the connection of structures such as the column 130 and the bearing seat 211.

[0038] Combining the above embodiments, it can be obtained that the hollow column 130 can effectively reduce the weight of the column 130 itself, and the side walls of the column 130 can fully support the upper frame 120 and the lower frame 180. Secondly, the hollow column 130 is convenient for drilling holes, so as to facilitate the installation of the energy storage module or other functional modules on the column 130. By sequentially passing the screw of the bolt 230 through the first mounting hole 121, the second mounting hole 121 and the first screw hole 2111, the column 130, the upper frame 120 and the connecting member 212 are screwed and fixed, so that when the connecting member 212 transmits force to the upper frame 120, the force is then transmitted to the column 130, thereby reducing the component force on the cabinet shell, evenly distributing the load, and improving the stress-bearing capacity of the connecting member 212.

[0039] In some embodiments, the first mounting hole 121 and the second mounting hole 121 are not provided with threads, which is beneficial to reducing the risk of interference and the installation process difficulty.

[0040] In some embodiments, please refer to Figure 4 and Figure 5 , the hoisting assembly 200 further includes a reinforcing member 240. The reinforcing member 240 is located inside the column 130. The reinforcing member 240 includes a first reinforcing piece 241 and a second reinforcing piece 242 connected to each other. The first reinforcing piece 241 and the second reinforcing piece 242 are arranged at an angle. The first reinforcing piece 241 is fixed to the inner side wall of the column 130. The second reinforcing piece 242 is provided with a third mounting hole 2421. The screw of the bolt 230 sequentially passes through the third mounting hole 2421, the first mounting hole 121 and the second mounting hole 121 and is screwed into the first screw hole 2111.

[0041] In some embodiments, the reinforcing piece is arranged in an "L" shape, and the angle between the first reinforcing piece 241 and the second reinforcing piece 242 is 90°. Thus, the thickness in the extending direction of the screw of the bolt 230 is increased to enhance the structural strength of the column 130 and the upper frame 120.

[0042] In some embodiments, in some embodiments, the angle can be 30°, 60° or 120° and other angles, so as to enhance the stress-bearing capacity of the column 130. It can be understood that inclined reinforcing ribs can also be provided between the first reinforcing piece 241 and the second reinforcing piece 242, so that the first reinforcing piece 241 and the second reinforcing piece 242 can also transmit force through the reinforcing ribs to enhance the stress-bearing capacity of the column 130. By providing the first reinforcing piece 241 and the second reinforcing piece 242, the contact area between the first reinforcing piece 241 and the second reinforcing piece 242 and the column 130 is increased, and the stress concentration phenomenon is reduced, preventing the connection between the column 130 and the connecting member 212 from being damaged due to excessive local stress when connected by the bolt 230.

[0043] In some embodiments, please refer toFigure 3 and Figure 4 , the hoisting assembly 200 (refer to Figure 1 ) further includes a gasket 250. The gasket 250 is sleeved on the screw rod of the bolt 230. Along the preset direction F, the gasket 250 is arranged between the second reinforcing piece 242 and the nut of the bolt 230. By providing the gasket 250, the contact area between the second reinforcing piece 242 and the bolt 230 is increased, the pressure on the surface of the nut of the bolt 230 is reduced, and the loosening of the screw connection is prevented.

[0044] In some embodiments, please refer to Figure 5 , the number of the third mounting holes 2421, the first mounting holes 121, the second mounting holes 121, the first screw holes 2111 and the bolts 230 are all multiple.

[0045] In some embodiments, the number of the third mounting holes 2421, the first mounting holes 121, the second mounting holes 121, the first screw holes 2111 and the bolts 230 are equal.

[0046] In some embodiments, the number of the third mounting holes 2421, the first mounting holes 121, the second mounting holes 121, the first screw holes 2111 and the bolts 230 are equal. The number of the third mounting holes 2421 can be any one of 2, 3, 4, 5, 6, 7 or 8, or any number between the two.

[0047] In some embodiments, multiple first screw holes 2111 are arranged in a ring shape on the load-bearing seat 211. The screw rod of a bolt 230 sequentially passes through a third mounting hole 2421, a first mounting hole 121 and a second mounting hole 121 and then is screwed to a first screw hole 2111.

[0048] Among them, the arrangement of multiple first screw holes 2111 in a ring shape can be understood as that multiple first screw holes 2111 are arranged in a circular ring shape, a triangular shape, a parallelogram shape, etc., which is beneficial to improving the connection strength between the load-bearing seat 211 and the column 130.

[0049] In this application, the description is made with the number being four, and other numbers will not be elaborated one by one. The load-bearing seat 211 is a cube. Four first screw holes 2111 are located at the four corners of the load-bearing seat 211. The screw rod of a bolt 230 sequentially passes through a third mounting hole 2421, a first mounting hole 121 and a second mounting hole 121 and then is screwed to a first screw hole 2111. Thus, the connection strength between the second reinforcing piece 242, the column 130 and the connecting piece 212 is uniformly strengthened from the four corners. And the distances between the above-mentioned bolts 230 can be equal, so as to evenly distribute the load.

[0050] In some embodiments, please refer to Figure 2, a receiving groove 122 is provided on the surface of the upper frame body 120 facing away from the column 130, and the load-bearing seat 211 is received in the receiving groove 122. The load-bearing seat 211 is arranged in the receiving groove 122, so that the occupied spaces of the upper frame body 120 and the load-bearing seat 211 in the preset direction F overlap, which is beneficial to reducing the occupied space of the load-bearing seat 211, and thus beneficial to reducing the overall occupied space of the cabinet 1000.

[0051] In some embodiments, the second mounting hole 121 is located at the bottom of the receiving groove 122. It can be understood that the receiving groove 122 is arranged in a "U" shape, so that at least three sides of the load-bearing seat 211 are in contact with the receiving groove 122, thereby increasing the connection strength between the load-bearing seat 211 and the column 130, and improving the force transmission ability between the load-bearing seat 211 and the column 130, so as to improve the force-bearing ability of the cabinet 1000.

[0052] In some embodiments, the receiving groove 122 and the load-bearing seat 211 are in interference fit, or through the provision of matching protrusions and grooves on the surfaces of the receiving groove 122 and the load-bearing seat 211 in contact, thereby further increasing the contact area between the receiving groove 122 and the load-bearing seat 211 to improve the connection strength. By providing the receiving groove 122, the connection parts between the upper frame body 120 and other structures can also be increased.

[0053] In some embodiments, for the above-mentioned lifting ring 220, please refer to Figure 2 , the lifting ring 220 includes a seat body 221 and an annular member 222, the annular member 222 is connected to the seat body 221, and the seat body 221 is fixed to the connecting member 212. By providing the seat body 221, the connection area between the lifting ring 220 and the connecting member 212 is increased, thereby enhancing the connection strength.

[0054] In some embodiments, the shape of the annular member 222 includes a circular ring shape, a square ring shape or a special-shaped ring shape with an opening.

[0055] In some embodiments, the annular member 222 is fixedly connected to the seat body 221, for example, by welding, integral forming, screwing and other methods.

[0056] In some other embodiments, the annular member 222 is rotatably connected to the seat body 221. In some embodiments, please refer to Figure 2 and Figure 3 , and in combination with other drawings, the part of the connecting member 212 extending out of the cabinet body 100 is provided with an external thread.

[0057] In some embodiments, the seat body 221 is provided with a second screw hole 2211, and a part of the connecting member 212 extending out of the first plate 110 is screwed into the second screw hole 2211, so that the seat body 221 and the connecting member 212 are detachably fixed. It can be understood that by setting the threaded connection, the connection strength between the connecting member 212 and the seat body 221 is improved, and the seat body 221 can also jointly clamp the cabinet shell with the connecting member 212 and the load-bearing seat 211. On the one hand, the contact area can be increased to improve the connection strength, and on the other hand, the force can be transmitted to other surfaces of the cabinet body 100 by clamping the first plate 110, so as to facilitate the direct hoisting of the cabinet body 100.

[0058] In some embodiments of the present application, please refer to Figure 2 , the hoisting assembly 200 further includes a backing plate 260. The backing plate 260 is provided with an opening 261. The backing plate 260 is disposed between the cabinet shell and the seat body 221. A part of the connecting member 212 extending out of the first plate 110 passes through the opening 261 and is screwed into the second screw hole 2211. By providing the backing plate 260 between the cabinet shell and the seat body 221, the contact area is increased, thereby facilitating the reduction of the stress concentration phenomenon of the seat body 221 on the cabinet shell.

[0059] In some embodiments of the present application, the cabinet 1000 of the present application is provided with four groups of lifting rings 220, which are respectively arranged at the four corners of the upper frame body 120 and the lower frame body 180. When the cabinet 1000 needs to be hoisted, installed or disassembled, taking the lifting ring 220 receiving a tensile force as an example: the tensile force is transmitted from the annular member 222 to the seat body 221, and the seat body 221 transmits the tensile force to the backing plate 260. A part of the tensile force transmitted to the backing plate 260 is transmitted towards the connecting member 212, and the other part is transmitted to the cabinet shell to balance the gravity received by the cabinet shell. The tensile force transmitted to the connecting member 212 is transmitted towards the load-bearing seat 211, and the load-bearing seat 211 is disposed in the receiving groove 122 and connected to the column 130, so that the tensile force is transmitted along the upper frame body 120 and the column 130 to the lower frame body 180, and further force can be applied through the gasket 250, the first reinforcing piece 241 and the second reinforcing piece 242, thereby enhancing the overall force-bearing capacity of the cabinet body 100.

[0060] In an embodiment of the present application, a cabinet 1000 is provided. The cabinet 1000 includes a cabinet body 100 and a hanging assembly 200.
