[0001] This application relates to the field of battery technology, and in particular to an energy storage rack. Background Technology

[0002] In the design of energy storage racks, the load-bearing capacity and stability of the racks are very important. Currently, energy storage racks are generally composed of beams and columns. As the main supporting components, the columns need to support the weight of the entire battery cluster. However, the overall strength of the existing columns is insufficient, resulting in low overall strength of the energy storage rack, limited load-bearing capacity, and poor stability. Summary of the Invention

[0003] The purpose of this application is to provide an energy storage rack with high structural strength.

[0004] To achieve the above objectives, this application provides an energy storage rack, which includes columns and beams, with the columns connected to the beams. The columns are hollow column structures formed by the joining of a first beam and a second beam. The first beam includes a first main body and a first connecting plate. The first main body has a first groove, and the first connecting plate is connected to both sides of the first main body, with the first connecting plate located at the opening of the first main body. The second beam includes a second main body and a second connecting plate. The second main body has a second groove, and the second connecting plate is connected to both sides of the second main body, with the second connecting plate located at the opening of the second main body. The two second connecting plates are respectively connected to the two first connecting plates, and the first groove and the second groove are connected to form a hollow cavity.

[0005] Compared with existing technologies, the above technical solution has the following advantages:

[0006] The first beam and the second beam are fixedly connected to each other by the first connecting plate and the second connecting plate. This connection method has a simple structure and is easy to connect, thereby improving the assembly efficiency of the column. In addition, the connection area between the first beam and the second beam is large, thereby ensuring the connection strength between the first beam and the second beam, ensuring the mechanical strength of the column formed by the first beam and the second beam, and thus ensuring the overall strength of the energy storage frame.

[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more apparent.

[0021] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0022] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The following discussion provides multiple embodiments of the present application. Although each embodiment represents a single combination of the application, different embodiments of the present application can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes A, B, and C, and another embodiment includes a combination of B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, even though such embodiments may not be explicitly described in the following content. In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0023] As Figures 1 to 7 shown, the energy storage rack provided by the present application includes columns 10 and cross beams 20. The columns 10 are connected to the cross beams 20. Specifically, the cross beam 20 is connected to the first connecting plate 112. In a specific embodiment of the present application, multiple columns 10 are arranged vertically, and multiple cross beams 20 are arranged horizontally. The columns 10 and the cross beams 20 are horizontally and vertically connected to form an energy storage rack. Specifically, both ends of each cross beam 20 are respectively connected to two columns 10, and the columns 10 are perpendicular to the cross beams 20. The columns 10 and the cross beams 20 enclose a receiving cavity for accommodating battery cassettes. In a preferred embodiment of the present application, the energy storage rack further includes diagonal beams 50. Both ends of the diagonal beams 50 are respectively connected to two columns 10, and the diagonal beams 50 are inclined with respect to the columns 10. The setting of the diagonal beams 50 increases the overall strength of the energy storage rack.

[0024] As Figure 3 、 Figures 6 to 7 shown, the column 10 is a hollow columnar structure formed by butting a first beam 11 and a second beam 12.

[0025] The first beam 11 includes a first main body 111 and a first connecting plate 112. The first main body 111 has a first groove 113. First connecting plates 112 are respectively connected to both sides of the first main body 111. Specifically, the two first connecting plates 112 are symmetrically arranged on both sides of the first main body 111 and are located at the opening of the first groove 113. The first connecting plate 112 is connected to the end of the first main body 111, making the first beam 11 as a whole in a "U" shape.

[0026] The second beam 12 includes a second main body 121 and second connecting plates 122. The second main body 121 has a second groove 123. The two sides of the second main body 121 are respectively connected with the second connecting plates 122. The two second connecting plates 122 are respectively correspondingly connected with the two first connecting plates 112. And the first groove 113 and the second groove 123 are communicated to form a hollow cavity, and the hollow cavity is the hollow part of a hollow cylinder. Along the direction in which the first connecting plate 112 is away from the first main body 111, the length of the second connecting plate 122 is less than that of the first connecting plate 112. Specifically, the two second connecting plates 122 are symmetrically arranged on the two sides of the second main body 121 and are located at the openings of the second groove 123. The second connecting plates 122 are connected to the ends of the second main body 121, so that the second beam 12 as a whole is in a "U" shape.

[0027] For the energy storage rack provided in the present application, the first beam 11 and the second beam 12 are fixedly connected through the first connecting plate 112 and the second connecting plate. This connection method has a simple structure and is convenient for connection, thereby improving the assembly efficiency of the column 10; and the connection area between the first beam 11 and the second beam 12 is relatively large, thereby ensuring the connection strength between the first beam 11 and the second beam 12, ensuring the mechanical strength of the first beam 11 and the second beam 12 constituting the column 10, and further ensuring the overall strength of the energy storage rack.

[0028] In addition, the communication between the first groove 113 and the second groove 123 forms a chamber in the middle of the column 10. On the one hand, on the premise of ensuring the overall strength of the column 10, the overall weight of the column 10 can be effectively reduced. On the other hand, the first beam 11 and the second beam 12 have a multi-folded edge structure, and the multi-folded edge structure is beneficial to increasing the mechanical strength of the first beam 11 and the second beam 12, so that the column 10 is not easily broken, not easily deformed, has high use reliability, and further improves the overall use reliability of the energy storage rack, reduces the probability of damage to the energy storage rack, prolongs the service life of the product, and increases the market competitiveness of the product. The multi-folded edge structure refers to a bent structure with three, four or more folded edges.

[0029] Such as Figure 3 、 Figures 6 to 8 As shown in the figure, in an embodiment of the present application, a reinforcing folded edge 14 is provided at one end of the first connecting plate 112 away from the first main body 111. Specifically, the reinforcing folded edge 14 is arranged perpendicular to the first connecting plate 112.

[0030] The reinforced folded edge 14 increases the number of folded edges on the first beam 11, giving it more folded structures and further increasing its mechanical strength. This makes the column 10 made from the first beam 11 less prone to breakage and deformation, resulting in higher reliability. Consequently, it improves the overall reliability of the energy storage rack, reduces the probability of rack damage, extends product lifespan, and enhances market competitiveness. Furthermore, the reinforced folded edge 14 eliminates sharp corners at the contact point between the column 10 and the battery compartment 60, preventing the column 10 from scratching the battery compartment 60 and ensuring the reliability of the battery compartment.

[0031] In another specific embodiment of this application, the end of the first connecting plate away from the first main body is bent toward the plate surface of the first connecting plate to form a folded edge. The plate surface of the folded edge is in contact with the plate surface of the first connecting plate, and the folded edge is parallel to the first connecting plate. The folded edge ensures that there are no sharp corners in the part of the column that contacts the battery box, thereby avoiding the situation where the column scratches the battery box and ensuring the reliability of the battery box.

[0032] like Figure 3 , Figure 6 and Figure 7 As shown, in one embodiment of this application, the first beam 11 is a beam formed by bending sheet metal. And / or the second beam 12 is a beam formed by bending sheet metal. That is, the first beam 11 and the second beam 12 are an integral structure manufactured using a one-piece molding process.

[0033] The bending and forming process is simple, easy to manufacture, and has high production efficiency, thereby reducing the production cost of the first beam 11 and the second beam 12 and increasing the product's market competitiveness. Furthermore, the first beam 11 and the second beam 12 are both integral structures, ensuring their overall strength, which in turn ensures the overall strength of the column 10 formed from the first beam 11 and the second beam 12. This makes the column 10 less prone to breakage and deformation, and ensures high reliability, thus improving the overall reliability of the energy storage rack.

[0034] like Figure 2 and Figure 3 As shown, in one embodiment of this application, a plurality of nuts 30 are provided on the first connecting plate 112, and through holes (not shown in the figure) are provided on the first connecting plate 112 corresponding to the threaded holes of the nuts 30.

[0035] One end of the screw passes through the crossbeam 20 and the through hole in sequence and is screwed into the nut 30. The other end of the screw interferes with the crossbeam 20. That is, the crossbeam 20 is fixed to the column 10 by the cooperation of the screw and the nut 30. The connection between the nut 30 and the screw is simple and has high connection strength, thereby increasing the fixing strength between the crossbeam 20 and the column 10, ensuring the overall strength of the energy storage frame, extending the service life of the product, and increasing the market competitiveness of the product.

[0036] like Figure 6 and Figure 7 As shown, in one embodiment of this application, the second connecting plate 122 extends to the nut 30. In a specific embodiment of this application, the length of the second connecting plate 122 is less than the length of the first connecting plate 112, so that the second connecting plate 122 does not interfere with the nut 30. In addition, the second connecting plate is also provided with a clearance groove corresponding to the nut.

[0037] The second connecting plate 122 extends to the nut 30, increasing the thickness of the first connecting plate 112 at that point. This makes the nut 30 more stable and securely fixed to the first beam 11, thereby ensuring the fixing strength between the crossbeam 20 and the column 10, which are fixedly connected by screws and the nut 30. This ensures the overall strength of the energy storage rack, extends the product's service life, and increases the product's market competitiveness.

[0038] like Figure 6 and Figure 7 As shown, in one embodiment of this application, the depth D1 of the first groove 113 is 1 to 4 times the depth D2 of the second groove 123. In a specific embodiment of this application, the depth D1 of the first groove 113 is the same as the depth D2 of the second groove 123.

[0039] By rationally configuring the depths of the first groove 113 and the second groove 123, the first beam 11 and the second beam 12 can be guaranteed to have greater strength, thereby ensuring the overall strength of the column 10 formed by the first beam 11 and the second beam 12. This makes the column 10 less prone to breakage and deformation, and more reliable in use. In turn, it improves the overall reliability of the energy storage rack, reduces the probability of damage to the energy storage rack, extends the service life of the product, and increases the product's market competitiveness.

[0040] like Figures 2 to 5 As shown, in one embodiment of this application, a plurality of functional holes 40 are provided on the first beam 11 and / or a plurality of functional holes 40 are provided on the second beam 12.

[0041] Functional holes 40 include, but are not limited to, weight-reducing holes, copper busbar holes, and cable routing holes. While ensuring the overall strength of the column 10, the weight-reducing holes are located on the second beam at the bottom of the second groove. These holes reduce the weight of the column 10, thereby lowering the overall weight of the energy storage rack and facilitating its handling. The copper busbar holes are located on the first beam on the side wall of the first groove, allowing copper busbars to pass through easily. The cable routing holes are also located on the first beam on the side wall of the first groove, enabling wires to be routed inside the column 10, facilitating wiring. Furthermore, when powder coating is required on the inner wall of the column 10, it can be done through the functional holes 40, facilitating the powder coating process.

[0042] In this application, the shape of the functional hole can be circular, oblong, elliptical, etc., which will not be listed here. In addition, the functional hole can be set at any position on the column as needed. Those skilled in the art can select the shape and setting position of the functional hole as needed.

[0043] like Figure 3 , Figure 6 and Figure 7 As shown, in one embodiment of this application, the column 10 further includes a reinforcing beam 13.

[0044] The reinforcing beam 13 is supported between the first beam 11 and the second beam 12, and the reinforcing beam 13 is fixedly connected to the first beam 11 and the second beam 12 respectively, that is, the reinforcing beam 13 is set in the hollow cavity of the column 10.

[0045] like Figure 2 and Figure 2a As shown, in a specific embodiment of this application, a reinforcing beam 13 is provided inside the column 10. The reinforcing beam 13 is arranged along the length direction L1 of the column 10. Specifically, the length of the reinforcing beam 13 is the same as the length of the column 10, so that the reinforcing beam 13 effectively supports the column 10. Or, as Figure 2b As shown, multiple reinforcing beams 13 are provided inside the column 10. The multiple reinforcing beams 13 are arranged along the length direction L1 of the column 10 and are equally spaced inside the column 10. While ensuring that the reinforcing beams 13 effectively support the column 10, the overall weight of the energy storage rack can be reduced.

[0046] The reinforcing beam 13 provides support for the first beam 11 and the second beam 12, improving the impact resistance of the column 10 and further increasing the overall strength of the column 10. This makes the column 10 less prone to breakage and deformation, and more reliable in use. Consequently, it improves the overall reliability of the energy storage rack, reduces the probability of damage to the energy storage rack, extends the product's service life, and increases the product's market competitiveness.

[0047] The following describes several embodiments of the reinforcing beam 13 with reference to the accompanying drawings:

[0048] Example 1

[0049] like Figure 6 As shown, in one embodiment of this application, the reinforcing beam 13 includes a first plate 131, a second plate 132 and a third plate 133 connected in sequence.

[0050] The first plate 131 and the third plate 133 are located on the same side of the second plate 132. The first plate 131 is connected to the first beam 11, and the third plate 133 is connected to the second beam 12. Specifically, the first plate 131 is connected to the bottom wall of the first groove 113, and the third plate 133 is connected to the bottom wall of the second groove 123. In a specific embodiment of this application, the surface of the first plate 131 is in contact with the bottom surface of the first groove 113; the surface of the third plate 133 is in contact with the bottom surface of the second groove 123.

[0051] The reinforcing beam 13 of the above structure is C-shaped. The first plate 131 ensures the connection area between the reinforcing beam 13 and the first beam 11, and the third plate 133 ensures the connection area between the reinforcing beam 13 and the second beam 12, thereby ensuring the connection strength between the reinforcing beam 13 and the first beam 11 and the second beam 12. The second plate 132 provides support for the first beam 11 and the second beam 12, so that the reinforcing beam 13 can effectively support the first beam 11 and the second beam 12, thereby improving the impact resistance of the column 10, further increasing the overall strength of the column 10, making the column 10 less prone to breakage and deformation, and ensuring high reliability. This, in turn, improves the overall reliability of the energy storage rack, reduces the probability of damage to the energy storage rack, extends the service life of the product, and increases the market competitiveness of the product.

[0052] Example 2

[0053] like Figure 7 As shown, in one embodiment of this application, the reinforcing beam 13 has a plurality of third grooves 134, and the opening directions of two adjacent third grooves 134 are opposite. In a specific embodiment of the application, the reinforcing beam 13 includes a plurality of vertical plates 135 and a plurality of horizontal plates 136, the horizontal plates 136 and the vertical plates 135 are alternately arranged, two vertical plates 135 and one horizontal plate 136 form a third groove 134, part of the horizontal plate 136 is in contact with the bottom surface of the first groove 113, and another part of the horizontal plate 136 is in contact with the bottom surface of the second groove 123, and the plurality of vertical plates 135 are supported between the first beam 11 and the second beam 12.

[0054] The reinforcing beam 13 of the above structure has a square wave shape, which gives it multiple connection surfaces with the first beam 11 and the second beam 12. This increases the connection area between the reinforcing beam 13 and the first beam 11 and the second beam 12, ensuring the connection strength between them. In addition, multiple parts of the reinforcing beam 13 provide support for the first beam 11 and the second beam 12, enabling it to effectively support them. This improves the impact resistance of the column 10, further increasing its overall strength and making it less prone to breakage and deformation, thus improving the overall reliability of the energy storage rack, reducing the probability of damage, extending the product's service life, and increasing its market competitiveness.

[0055] Those skilled in the art should understand that, in addition to the shapes described above, reinforcing beams can also be I-shaped, Z-shaped, U-shaped, etc., which will not be listed here.

[0056] In the description of this application, it should be noted that the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Unless otherwise expressly stated and limited, this also applies to other applications.

[0057] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. The term "multiple" refers to two or more, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0058] The present application has been described above with reference to preferred embodiments; however, these embodiments are merely exemplary and illustrative. Various substitutions and modifications can be made to the present application based on these embodiments, all of which fall within the protection scope of the present application.
