[0035] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 6 A battery rack 100 for an energy storage system 200 according to an embodiment of the first aspect of the utility model is described.

[0036] like Figure 1As shown, a battery rack 100 for an energy storage system 200 according to an embodiment of the first aspect of the utility model includes a body 1 and at least one bracket assembly 2.

[0037] Specifically, the bracket assembly 2 is disposed on the body 1, and the bracket assembly 2 includes a plurality of brackets 21, and the plurality of brackets 21 are arranged along the height direction of the body 1 (for example, Figure 1 In the description of the present utility model, the meaning of "multiple" is two or more. For example, in Figure 1 In the example, the bracket assembly 2 is arranged in the thickness direction of the body 1 (for example, Figure 1 On one side of the battery rack 100 (in the front-to-back direction), the bracket assembly 2 includes four brackets 21, and the four brackets 21 are arranged at intervals along the height direction of the main body 1. When the battery rack 100 is assembled, the integrated bracket assembly 2 can be directly positioned and fixed on the main body 1 so that multiple brackets 21 are installed on the main body 1, avoiding the operation of assembling each bracket 21 with the main body 1 separately, and reducing the time for welding or installing a single bracket 21, thereby simplifying the installation operation of the battery rack 100, shortening the installation time of the battery rack 100, and improving the assembly efficiency of the battery rack 100. In addition, after the multiple brackets 21 are welded together into a whole, it is convenient for the overall spraying, and there is no missing internal corner. It should be noted that the number and spacing of the brackets 21 in the bracket assembly 2 can be specifically set according to actual use to better meet practical applications.

[0038] According to the battery rack 100 for the energy storage system 200 of the embodiment of the utility model, by connecting multiple brackets 21 into an integrated bracket assembly 2, during the installation process of the battery rack 100, the battery bracket 21 can be directly connected to the main body 1 to achieve the connection between the multiple brackets 21 and the main body 1, which simplifies the installation operation of the battery rack 100, shortens the installation time of the battery rack 100, and improves the assembly efficiency of the battery rack 100.

[0039] According to some embodiments of the present invention, Figure 2 The bracket assembly 2 further includes at least one support member 22, the support member 22 extends along the height direction of the body 1, and the support member 22 is respectively connected to the plurality of brackets 21. Figure 2 In the example, two support members 22 can be provided, and both support members 22 extend in the up-down direction, and each support member 22 is connected to four brackets 21 respectively, and one of the two support members 22 is connected in the length direction of the adjacent multiple brackets 21 (that is, Figure 1 in the left and right directions) at the same end (for example, Figure 2The other of the two supports 22 is connected to the middle position of the plurality of brackets 21. Thus, by providing the support 22, the plurality of brackets 21 can be connected as a whole, so as to facilitate the connection between the bracket assembly 2 and the body 1. In addition, the structural strength of the bracket assembly 2 can be enhanced, and the bracket assembly 2 is not easily deformed during use, which is conducive to the long-term and stable use of the bracket assembly 2 and extends the service life of the battery rack 100. For example, the support 22 is welded to the plurality of brackets 21 respectively to improve the connection strength between the support 22 and the bracket 21.

[0040] Further, refer to Figure 2 and Figure 3 The bracket assembly 2 includes a stopper 23, which is disposed at the same end of the length direction of the plurality of brackets 21. The stopper 23 is connected to the plurality of brackets 21 respectively, and the plane where the stopper 23 is located is perpendicular to the length direction of the bracket 21. For example, Figure 2 and Figure 3 In the example, the limiter 23 is disposed at the right end of the multiple brackets 21 and is connected to the multiple brackets 21, and the limiter 23 extends in the front-to-back direction. In this way, the limiter 23 can limit the movement of the battery pack on the bracket 21, that is, when the battery pack is installed on the bracket 21, the battery pack can move from the end of the bracket 21 away from the limiter 23 to the bracket 21, and the limiter 23 can limit the battery pack from continuing to move toward the right end of the bracket 21, so as to be more conducive to the installation of the battery pack, thereby being more conducive to the use of the battery rack 100, and improving the performance of the battery rack 100. In addition, the limiter 23 has a simple structure and is easy to produce and process, thereby improving the production efficiency of the bracket assembly 2. For example, the limiter 23 is welded to the multiple brackets 21 respectively to improve the connection strength between the limiter 23 and the bracket 21, thereby improving the structural strength of the bracket assembly 2.

[0041] According to some embodiments of the present invention, Figure 2 and Figure 3 The bracket 21 includes a connecting section 211 and a supporting section 212. The connecting section 211 extends along the width direction of the body 1. The connecting section 211 is connected to the body 1. The supporting section 212 is connected to the connecting section 211. The plane where the supporting section 212 is located is perpendicular to the plane where the connecting section 211 is located. For example, Figure 2 and Figure 3In the example, the connecting section 211 is connected to one side surface of the body 1 in the thickness direction, the supporting section 212 is connected to the lower side of the connecting section 211, and the cross-sectional area of ​​the bracket 21 is roughly "L"-shaped. When the battery rack 100 is used in the energy storage system 200, the edge of the battery pack can be placed on the supporting section 212 so that the battery pack is placed on the battery rack 100. In this way, the bracket 21 can be connected to the body 1 through the connecting section 211, and the battery pack can be supported by the supporting section 212 so that the battery pack can be installed in the energy storage system 200. In addition, the bracket 21 has a simple structure, is easy to produce and process, and has a low production cost.

[0042] According to some embodiments of the present invention, referring to Figure 2-Figure 4 A plurality of first positioning holes 11 are formed on the body 1, a plurality of second positioning holes 2111 are formed on the connecting section 211 of at least one of the plurality of brackets 21, the plurality of second positioning holes 2111 are arranged at intervals along the length direction of the bracket 21, the plurality of second positioning holes 2111 are respectively opposite to the plurality of first positioning holes 11, and the battery rack 100 further includes a plurality of positioning members (not shown in the figure), the positioning members pass through the second positioning holes 2111 and the first positioning holes 11.

[0043] For example, in Figure 1-Figure 4 In the example of , the body 1 includes three columns 13, which are arranged along the width direction of the body 1 (that is, the length direction of the bracket 21), and two first positioning holes 11 can be formed on each column 13, and six second positioning holes 2111 are formed on one of the multiple brackets 21 of the bracket assembly 2, and the six second positioning holes 2111 are respectively opposite to the first positioning holes 11 on the corresponding column 13. In this way, when the bracket assembly 2 is assembled with the body 1, the bracket assembly 2 can be more accurately installed at the specified position on the body 1 through the positioning member, the first positioning hole 11 and the second positioning hole 2111. Compared with the conventional technology in which each bracket 21 is positioned with the body 1 separately, the positioning time of multiple brackets 21 and the body 1 can be shortened. For example, one of the four brackets 21 in the bracket assembly 2 can be directly positioned with the body 1, thereby improving the assembly efficiency of the bracket assembly 2 and the body 1. For example, the first positioning hole 11 and the second positioning hole 2111 can be accurately opened by laser to improve the accuracy of the installation position of the bracket assembly 2, and also ensure the horizontality of the two ends of the length direction of the bracket 21. It should be noted that the number of the first positioning holes 11 and the second positioning holes 2111 can be set according to the specific use to better meet the actual application. For example, the positioning member can be a rivet positioning, but is not limited thereto.

[0044] According to some embodiments of the present invention, Figure 2 , a plurality of second positioning holes 2111 are formed on the connecting section 211 of each bracket 21. For example, Figure 2In the example, a plurality of second positioning holes 2111 are respectively formed on the four brackets 21 in the bracket assembly 2, and the structures of the plurality of brackets 21 are completely the same. With such a configuration, it is not easy to mis-install when the plurality of brackets 21 are connected to form the bracket assembly 2, and it is not necessary to distinguish the plurality of brackets 21 on the bracket assembly 2, thereby improving the installation efficiency of the bracket assembly 2, and further improving the production efficiency of the battery rack 100.

[0045] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 A plurality of reinforcing members 213 are welded to one side of the support section 212 of each bracket 21 away from the connecting section 211, and the plurality of reinforcing members 213 are arranged at intervals along the length direction of the bracket 21. Figure 2 and Figure 3 In the example, three reinforcement members 213 are welded on the lower surface of the support section 212 of each bracket 21, and the three reinforcement members 213 are arranged at intervals along the length direction of the bracket 21. In this way, the reinforcement member 213 supports the support section 212, thereby strengthening the supporting effect of the support section 212 on the battery pack. In addition, the structural strength of the support section 212 is also strengthened, which is conducive to the long-term and stable use of the bracket 21 and prolongs the service life of the bracket 21. For example, the shape of the reinforcement member 213 is roughly "L"-shaped, and the horizontal section of the reinforcement member 213 is welded to the support section 212. As a result, the structure of the reinforcement member 213 is simple, and the connection between the reinforcement member 213 and the bracket 21 is relatively tight, which improves the stability of the bracket 21.

[0046] According to some embodiments of the present invention, Figure 2-Figure 4 A plurality of first fixing holes 12 are formed on the main body 1, and at least one second fixing hole 2131 is formed on each reinforcement member 213. The battery rack 100 further includes a plurality of fixing members 3, and one end of the fixing member 3 is penetrated by the second fixing hole 2131 and the first fixing hole 12 and connected to the main body 1.

[0047] For example, in Figure 2-Figure 4In the example, two second fixing holes 2131 are formed on each reinforcement member 213, and a first fixing hole 12 is reserved at the corresponding position of the body 1 and the bracket assembly 2. The first fixing hole 12 can be accurately opened on the body 1 by laser, and the fixing member 3 can be set as a bolt, which is connected to the body 1 through the second fixing hole 2131 and the first fixing hole 12 to fix the bracket 21 locally. In this way, each bracket 21 can be firmly mounted on the body 1 through the fixing member 3, and it is also convenient for the installation and removal of the bracket 21. In addition, when the fixing of a fixing member 3 in the bracket assembly 2 fails, since the multiple brackets 21 in the bracket assembly 2 are welded into a whole through the support member 22, the fixing member 3 that has not failed will weaken the failure effect, ensure that the overall performance meets the functional requirements, and the overall performance will be more stable. In addition, the bracket assembly 2 and the body 1 can be powder-sprayed separately, that is, the body 1 can complete the cylindrical powder spraying before installing the bracket assembly 2, and the large surface powder spraying is uniform, without dead angles, and the waste of paint powder is reduced. Then the bracket assembly 2 is also powder-sprayed separately and then connected to the main body 1, so that there is no dead angle in the powder spraying of the bracket assembly 2. The present application adopts an integrated method combining welding and connection with a fixing member 3. The bracket assembly 2 composed of multiple brackets 21 is welded together through a support member 22 and then positioned and fixed on the main body 1 as a whole with a fixing member 3. This can achieve the stability and strength of welding, and can also meet the advantages of convenient spraying and reduced installation workload. It should be noted that the number of the first fixing hole 12 and the second fixing hole 2131 can be set according to the specific use to better meet the actual application.

[0048] According to some embodiments of the present invention, Figure 1 There are multiple bracket assemblies 2, and the multiple bracket assemblies 2 constitute a first bracket group 24 and a second bracket group 25. The first bracket group 24 and the second bracket group 25 are respectively arranged on both sides of the thickness direction of the body 1. The first bracket group 24 includes multiple first bracket assemblies 241, and the multiple first bracket assemblies 241 are arranged along the height direction of the body 1. The second bracket group 25 includes multiple second bracket assemblies 2, and the multiple second bracket assemblies 2 are arranged along the height direction of the body 1.

[0049] For example, in Figure 1In the example, the first bracket group 24 is installed on the front side of the body 1, and the second bracket group 25 is installed on the rear side of the body 1. The first bracket group 24 includes two first bracket assemblies 241, and the two first bracket assemblies 241 are arranged in the up-down direction. The second bracket group 25 includes two second bracket assemblies 2, and the two second bracket assemblies 2 are arranged in the up-down direction. As a result, multiple brackets 21 can be installed on both sides of the thickness direction of the body 1. When the battery rack 100 is used for the energy storage system 200, the corresponding brackets 21 of the two adjacent battery racks 100 can jointly support the battery pack, and multiple battery packs can be installed, thereby effectively utilizing the space on the body 1, thereby improving the space utilization rate inside the energy storage system 200, and improving the performance of the energy storage system 200. In addition, it is more conducive to the installation of the body 1 and multiple brackets 21, and further improves the assembly efficiency of the battery rack 100.
