Description

Technical Field

[0001] This application relates to the field of energy storage equipment technology, specifically to a load-bearing beam, a container, and an energy storage box. Background Technology

[0002] An energy storage container is a modular and standardized integrated energy storage system that uses a container as a carrier to integrate core equipment such as battery packs, battery management systems (BMS), power conversion systems (PCS), thermal management systems, and fire-fighting devices, thereby enabling the storage and flexible dispatch of electrical energy.

[0003] Conventional energy storage containers consist of interconnected crossbeams, longitudinal beams, and vertical beams forming a frame. The crossbeams, as the main load-bearing beams, have high strength design requirements. Common load-bearing beam designs include square tube, channel steel, and I-beam designs. The square tube design uses a single rectangular tube without any internal filling, thus requiring a high wall thickness. The channel steel design consists of two sections of channel steel welded together to form a rectangular tube; due to the lack of internal filling, the channel steel also requires a high wall thickness. The I-beam design uses an I-beam structure for the bottom crossbeams; however, the structural characteristics of I-beams necessitate a high thickness requirement. Because conventional load-bearing beams are structurally limited and require significant material thickness, they are inherently heavy.

[0004] Therefore, how to solve or improve the problem that the load-bearing beams in related technologies need to be designed with a large material thickness, resulting in a large weight, has become an important technical problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, this application provides a load-bearing beam, a container, and an energy storage box to solve or improve the problem that the load-bearing beam requires a large material thickness, resulting in a large weight.

[0006] In a first aspect, this application provides a load-bearing beam, comprising: The main body of the load-bearing beam; The first reinforcing rib is connected to the main body of the load-bearing beam; The second reinforcing rib is connected to the main body of the load-bearing beam and abuts against the first reinforcing rib.

[0007] Beneficial effects: Both the first and second reinforcing ribs enhance the load-bearing capacity of the main beam. Furthermore, the mutual contact between the first and second reinforcing ribs strengthens their reinforcing effect, further enhancing the load-bearing capacity of the main beam. Because the performance of the load-bearing beam is further enhanced, the wall thickness of the main beam can be reduced while still meeting load-bearing requirements, thus reducing the weight of the main beam.

[0008] In one optional embodiment, the main body of the load-bearing beam extends along a first direction and is provided with an inner hole, the inner hole having a first inner wall and a second inner wall disposed opposite to each other; The first reinforcing rib is disposed in the inner hole and connected between the first inner wall and the second inner wall, and the first reinforcing rib extends along the first direction; The second reinforcing rib is disposed in the inner hole and connected between the first inner wall and the second inner wall, and the second reinforcing rib extends along the first direction.

[0009] Beneficial Effects: When using the load-bearing beam of this embodiment, the load acts on the outer wall of the main body of the load-bearing beam, which is opposite to the first inner wall, and points towards the second inner wall. At this time, not only the main body of the load-bearing beam bears the load, but the first and second reinforcing ribs also provide support between the first and second inner walls, thus enabling them to bear the load and enhancing the load-bearing capacity of the beam. Furthermore, because the first and second reinforcing ribs abut against each other, they support each other, making it difficult for them to deform towards each other, further enhancing their load-bearing capacity and thus further strengthening the load-bearing capacity of the beam. Because the performance of the load-bearing beam is further enhanced, the wall thickness of the main body of the load-bearing beam can be reduced while ensuring the load-bearing requirements are met, thereby reducing the weight of the main body of the load-bearing beam.

[0010] In one optional embodiment, the first reinforcing rib includes: The first curved section is bent towards the second reinforcing rib, and the side of the first curved section closest to the second reinforcing rib abuts against the second reinforcing rib.

[0011] Beneficial effects: Because the first bending segment bends towards the second reinforcing rib, when the load is transferred to the side of the first bending segment closest to the second reinforcing rib, the load is decomposed into a first lateral component and a first longitudinal component. The first lateral component is borne by the second reinforcing rib. The first reinforcing rib only needs to bear the first longitudinal component, which is less than the original load, thereby enhancing the load-bearing capacity of the first reinforcing rib.

[0012] In one optional embodiment, multiple first bending segments are provided, and the multiple first bending segments are connected in sequence to form a corrugated shape; the side of each first bending segment near the second reinforcing rib abuts against the second reinforcing rib.

[0013] Beneficial effects: The load is decomposed into multiple first lateral components and multiple first longitudinal components at multiple first bending segments. The multiple first lateral components are borne by the second stiffener, thereby further enhancing the load-bearing performance of the first stiffener.

[0014] In one optional embodiment, the second reinforcing rib includes: The second bending segment is bent towards the first reinforcing rib, and the side of the second bending segment closest to the second reinforcing rib abuts against the first bending segment.

[0015] Beneficial effects: Because the second bending segment bends towards the first reinforcing rib, when the load is transferred to the side of the second bending segment closest to the first reinforcing rib, the load is decomposed into a second lateral component and a second longitudinal component. Since the second bending segment abuts against the first bending segment, the first lateral component and the second lateral component cancel each other out, reducing the lateral load borne by the first and second reinforcing ribs, thereby enhancing the load-bearing capacity of the first and second reinforcing ribs.

[0016] In one optional embodiment, multiple first and second curved segments are provided, and multiple second curved segments are connected in sequence to form a corrugated shape, with the sides of each first curved segment and each second curved segment corresponding to each other and abutting against each other.

[0017] Beneficial effects: The load is decomposed into multiple first lateral components and multiple first longitudinal components at multiple first bending sections, and into multiple second lateral components and multiple second longitudinal components at multiple second bending sections. Each first lateral component and each second lateral component cancel each other out, further reducing the lateral load borne by the first and second reinforcing ribs, thereby further enhancing the load-bearing performance of the first and second reinforcing ribs.

[0018] In one optional embodiment, the bending angle of the first bending segment and / or the bending angle of the second bending segment are in the range of 15° to 30°, and the first inner wall and the second inner wall are disposed opposite each other along the second direction; The bending angle of the first bending segment is the angle between the tangent at the end of the first bending segment and the second direction; The bending angle of the second bending segment is the angle between the tangent at the end of the second bending segment and the second direction.

[0019] Beneficial effects: When the bending angle R1 of the first bending segment is in the range of 15° to 30°, the degree of bending of the first bending segment toward the direction of the second reinforcing rib is moderate. When the load is decomposed into the first lateral component and the first longitudinal component, not only is the load-bearing capacity of the first reinforcing rib greatly improved, but the second reinforcing rib can also withstand the first lateral component. When the bending angle R1 of the second bending segment is in the range of 15° to 30°, the degree of bending of the second bending segment toward the first reinforcing rib is moderate. When the load is decomposed into the second lateral component and the second longitudinal component, not only is the load-bearing capacity of the second reinforcing rib greatly improved, but the first reinforcing rib can also withstand the second lateral component.

[0020] In one optional embodiment, the first reinforcing rib includes: The first connecting segment is fitted and connected to the first inner wall; The second connecting segment is fitted and connected to the second inner wall, and the first reinforcing rib is connected between the first connecting segment and the second connecting segment. And / or, the second reinforcing rib includes: The third connecting segment is fitted and connected to the first inner wall; The fourth connecting segment is fitted and connected to the second inner wall, and the second reinforcing rib is connected between the third connecting segment and the fourth connecting segment.

[0021] Beneficial effects: Because the first connecting segment is attached to the first inner wall, the contact area between the first connecting segment and the first inner wall is larger, thus making the support of the first reinforcing rib to the first inner wall more stable and reliable. Because the second connecting segment is attached to the second inner wall, the contact area between the second connecting segment and the second inner wall is larger, thus making the support of the first reinforcing rib to the second inner wall more stable and reliable. Because the third connecting segment is fitted to the first inner wall, the contact area between the third connecting segment and the first inner wall is larger, thus making the support of the second reinforcing rib to the first inner wall more stable and reliable. Because the fourth connecting segment is fitted to the second inner wall, the contact area between the fourth connecting segment and the second inner wall is larger, thus making the support of the second reinforcing rib to the second inner wall more stable and reliable.

[0022] In one optional embodiment, the main body of the load-bearing beam includes a first U-shaped beam and a second U-shaped beam. The second U-shaped beam is disposed inside the first U-shaped beam. The two sides of the second U-shaped beam are respectively connected to the inner wall of the first U-shaped beam. The opening directions of the first U-shaped beam and the second U-shaped beam are opposite to each other. The first U-shaped beam and the second U-shaped beam enclose and form the inner hole.

[0023] Beneficial effects: The combination of the first U-shaped beam and the second U-shaped beam forms the main load-bearing beam, which has a stronger load-bearing capacity than the square tube structure and has a lower manufacturing cost.

[0024] Secondly, this application also provides a container, including crossbeams, longitudinal beams and vertical beams connected to each other to form a frame, wherein the crossbeams are configured as any of the load-bearing beams described above.

[0025] Beneficial effects: The technical effects brought by this container are the same as those of the load-bearing beam, so they will not be elaborated further.

[0026] Thirdly, this application also provides an energy storage box, including an outer casing and a battery module disposed within the outer casing, wherein the outer casing is provided with any of the aforementioned load-bearing beams, or is configured as the aforementioned container.

[0027] Beneficial effects: The technical effects brought by this energy storage box are the same as those of containers or load-bearing beams, so they will not be elaborated further. Attached Figure Description

Detailed Implementation To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The following is combined with Figures 1 to 7This describes an embodiment of the present application.

[0032] According to embodiments of this application, in one aspect, a load-bearing beam is provided, such as... Figure 1 and Figure 2 As shown, Includes: the main body of the load-bearing beam 1, the first reinforcing rib 2, and the second reinforcing rib 3.

[0033] The first reinforcing rib 2 is connected to the main body 1 of the load-bearing beam, and the second reinforcing rib 3 is connected to the main body 1 of the load-bearing beam, with the first reinforcing rib 2 and the second reinforcing rib 3 abutting against each other.

[0034] This configuration enhances the load-bearing capacity of the main beam 1 by both the first reinforcing rib 2 and the second reinforcing rib 3. Furthermore, the mutual contact between the first reinforcing rib 2 and the second reinforcing rib 3 strengthens their reinforcing effect, further enhancing the load-bearing capacity of the main beam 1. Because the performance of the load-bearing beam is further enhanced, the wall thickness of the main beam 1 can be reduced while ensuring load-bearing requirements are met, thereby reducing the weight of the main beam 1.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, the supporting beam body 1 is arranged along a first direction X, which is the length direction of the supporting beam body 1. An inner hole is formed inside the supporting beam body 1 along the first direction X. The inner hole has a first inner wall 101 and a second inner wall 102, wherein the first inner wall 101 and the second inner wall 102 are arranged opposite to each other, so that a placement space is formed between the first inner wall 101 and the second inner wall 102 for placing the first reinforcing rib 2 and the second reinforcing rib 3.

[0036] The first reinforcing rib 2 is disposed in the inner hole of the main body of the supporting beam 1 and extends along the first direction X. One side of the rib is connected to the first inner wall 101 and the other side is connected to the second inner wall 102, so that the first reinforcing rib 2 is connected between the first inner wall 101 and the second inner wall 102.

[0037] The second reinforcing rib 3 is disposed within the inner hole of the main body of the supporting beam 1 and extends along the first direction X. One side of the rib is connected to the first inner wall 101, and the other side is connected to the second inner wall 102, thereby connecting the second reinforcing rib 3 between the first inner wall 101 and the second inner wall 102. Furthermore, the sides of the first reinforcing rib 2 and the second reinforcing rib 3 that are close to each other abut against each other, making it difficult for the first reinforcing rib 2 and the second reinforcing rib 3 to come into close proximity and deform.

[0038] With this configuration, the load-bearing direction of the load-bearing beam is from the first inner wall 101 to the second inner wall 102. When using the load-bearing beam of this embodiment, the load acts on the outer wall of the main body 1 of the load-bearing beam, which is opposite to the first inner wall 101, and points towards the second inner wall 102. At this time, not only the main body 1 of the load-bearing beam bears the load, but the first reinforcing rib 2 and the second reinforcing rib 3 also provide support between the first inner wall 101 and the second inner wall 102, and the direction of the support is consistent with the load direction. Therefore, the first reinforcing rib 2 and the second reinforcing rib 3 can also bear the load, thus enhancing the load-bearing performance of the load-bearing beam.

[0039] Moreover, since the first reinforcing rib 2 and the second reinforcing rib 3 abut against each other, they support each other, making it difficult for them to deform towards each other, thus enhancing the load-bearing capacity of the first reinforcing rib 2 and the second reinforcing rib 3, and further enhancing the load-bearing capacity of the load-bearing beam.

[0040] Because the performance of the load-bearing beam is further enhanced, the wall thickness of the main body 1 of the load-bearing beam can be reduced while ensuring the load-bearing requirements are met, thereby reducing the weight of the main body 1 of the load-bearing beam.

[0041] In one embodiment, such as Figure 1 and Figure 2 As shown, the first reinforcing rib 2 includes a first bent section 21, which is bent toward the second reinforcing rib 3, and the side of the first bent section 21 that is near the second reinforcing rib 3 abuts against the second reinforcing rib 3.

[0042] Thus, when the load acts on the outer wall of the main beam 1, which is opposite to the first inner wall 101, part of it is borne by the first reinforcing rib 2. Since the first curved section 21 bends towards the second reinforcing rib 3, when the load is transmitted to the side of the first curved section 21 near the second reinforcing rib 3, the direction of the load tilts towards the second reinforcing rib 3, thereby decomposing into a first lateral component F1 and a first longitudinal component. Because the side of the first curved section 21 near the second reinforcing rib 3 abuts against the second reinforcing rib 3, the first lateral component F1 is borne by the second reinforcing rib 3. The first reinforcing rib 2 only needs to bear a first longitudinal component less than the original load, thereby enhancing the load-bearing capacity of the first reinforcing rib 2 and further enhancing the load-bearing capacity of the main beam.

[0043] The first curved segment 21 can be arc-shaped.

[0044] The first reinforcing rib 2 also includes an arc-shaped first transition section, which is disposed at both ends of the first curved section 21 to form an arc transition at both ends of the first curved section 21.

[0045] In one embodiment, such as Figure 1 and Figure 2As shown, multiple first bending segments 21 are provided, and the multiple first bending segments 21 are connected sequentially from the first inner wall 101 to the second inner wall 102, forming a corrugated shape. The side of each first bending segment 21 closest to the second reinforcing rib 3 abuts against the second reinforcing rib 3.

[0046] When the load acts on the outer wall of the main beam 1, which is opposite to the first inner wall 101, part of it is borne by the first reinforcing rib 2. Therefore, when the load is transferred to the side of each first bending segment 21 near the second reinforcing rib 3, it is decomposed into a first lateral component F1 and a first longitudinal component. Since the side of each first bending segment 21 near the second reinforcing rib 3 abuts against the second reinforcing rib 3, the first lateral component F1 at each first bending segment 21 is borne by the second reinforcing rib 3.

[0047] In this way, the load borne by the first reinforcing rib 2 is decomposed into multiple first transverse components F1, and only needs to bear the remaining first longitudinal component, thereby further enhancing the load-bearing capacity of the first reinforcing rib 2.

[0048] For the two first transition segments between the two first bending segments 21, the two are smoothly connected to form an arc transition.

[0049] In one embodiment, such as Figure 1 and Figure 2 As shown, based on the first reinforcing rib 2 including a first bent section 21, the second reinforcing rib 3 includes a second bent section 31. The second bent section 31 is bent towards the first reinforcing rib 2, and the side of the second bent section 31 closest to the first reinforcing rib 2 abuts against the first bent section 21.

[0050] Thus, when the load acts on the outer wall of the main body 1 of the load-bearing beam, which is opposite to the first inner wall 101, part of it is borne by the second reinforcing rib 3. Since the second curved section 31 bends towards the first reinforcing rib 2, when the load is transmitted to the side of the second curved section 31 near the first reinforcing rib 2, the direction of the load tilts towards the first reinforcing rib 2, thereby decomposing into a second lateral component F2 and a second longitudinal component. Because the side of the second curved section 31 near the first reinforcing rib 2 abuts against the first curved section 21, the second lateral component F2 is borne by the first curved section 21 of the first reinforcing rib 2. The second reinforcing rib 3 only needs to bear a second longitudinal component less than the original load, thereby enhancing the load-bearing capacity of the second reinforcing rib 3 and further enhancing the load-bearing capacity of the load-bearing beam.

[0051] The second curved segment 31 can be arc-shaped.

[0052] Furthermore, since the first curved segment 21 bends towards the second reinforcing rib 3, the first lateral force F1 points towards the second reinforcing rib 3. Since the second curved segment 31 bends towards the first reinforcing rib 2, the second lateral force F2 points towards the first reinforcing rib 2, that is, the directions of the first lateral force F1 and the second lateral force F2 are opposite.

[0053] Furthermore, since the second bending segment 31 abuts against the first bending segment 21, the points of application of the first lateral component force F1 and the second lateral component force F2 coincide and cancel each other out. This reduces the lateral load borne by the first reinforcing rib 2 and the second reinforcing rib 3, thereby enhancing the load-bearing capacity of the first reinforcing rib 2 and the second reinforcing rib 3.

[0054] The first reinforcing rib 2 can have the same shape and size, that is, the first bending segment 21 and the second bending segment 31 have the same shape and size, so that the first lateral component force F1 and the second lateral component force F2 are the same, and thus the first lateral component force F1 and the second lateral component force F2 can cancel each other out, so that the first reinforcing rib 2 and the second reinforcing rib 3 do not bear lateral load, avoid lateral deformation of the first reinforcing rib 2 and the second reinforcing rib 3, and enhance the load-bearing capacity of the first reinforcing rib 2 and the second reinforcing rib 3.

[0055] The second reinforcing rib 3 also includes an arc-shaped second transition section, which is disposed at both ends of the second curved section 31 to form an arc transition at both ends of the second curved section 31.

[0056] In one embodiment, such as Figure 1 and Figure 2 As shown, based on the first reinforcing rib 2 including a first curved section 21 and the second reinforcing rib 3 including a second curved section 31, multiple first curved sections 21 and multiple curved sections 31 are provided. Multiple first curved sections 21 are connected sequentially from the first inner wall 101 to the second inner wall 102, forming a corrugated shape. Multiple second curved sections 31 are connected sequentially from the first inner wall 101 to the second inner wall 102, forming a corrugated shape. The number of first curved sections 21 and second curved sections 31 is the same.

[0057] For each first bending segment 21 and each second bending segment 31, each first bending segment 21 abuts against a corresponding second bending segment 31.

[0058] Thus, when the load is applied to the outer wall of the main beam 1 that is opposite to the first inner wall 101, part of it is borne by the first reinforcing rib 2 and part of it is borne by the second reinforcing rib 3.

[0059] For the first reinforcing rib 2, when the load is transmitted to the side of each first bending segment 21 that is close to the second reinforcing rib 3, the direction of the load on each first bending segment 21 is inclined toward the direction close to the second reinforcing rib 3, so that the load on each first bending segment 21 is decomposed into a first lateral component force F1 and a first longitudinal component force, wherein the first lateral component force F1 points toward the second reinforcing rib 3.

[0060] For the second reinforcing rib 3, when the load is transmitted to the side of the second bending segment 31 that is close to the first reinforcing rib 2, the direction of the load on each second bending segment 31 is inclined toward the direction close to the first reinforcing rib 2, so that the load on each second bending segment 31 is decomposed into a second lateral component force F2 and a second longitudinal component force, wherein the second lateral component force F2 points toward the first reinforcing rib 2.

[0061] Since the first bending segment 21 and the second bending segment 31 are adjacent to each other on one side, the first lateral force F1 on the first bending segment 21 and the second lateral force F2 on the second bending segment 31 cancel each other out, thereby reducing the lateral load borne by the first reinforcing rib 2 and the second reinforcing rib 3.

[0062] For the first reinforcing rib 2, the load it bears is decomposed into multiple first transverse components F1 at multiple first bending segments 21, leaving only multiple first longitudinal components. Each first transverse component F1 is then canceled out by the second bending segment 31, thereby enhancing the load-bearing capacity of the first reinforcing rib 2.

[0063] For the second reinforcing rib 3, the load it bears is decomposed into multiple second transverse components F2 at multiple second bending segments 31, leaving only multiple second longitudinal components. Each second transverse component F2 is then canceled out by the first bending segment 21, thereby enhancing the load-bearing capacity of the second reinforcing rib 3.

[0064] For the two second transition segments between the two second curved segments 31, the two are smoothly connected to form an arc transition.

[0065] The first inner wall 101 and the second inner wall 102 are arranged along the second direction Y, that is, the first inner wall 101 and the second inner wall 102 are arranged opposite to each other along the second direction Y.

[0066] In one embodiment, the bending angle R1 of the first bending segment 21 is in the range of 15° to 30°, such as 15°, 20° or 30°.

[0067] like Figure 3 As shown, the bending angle R1 of the first bending segment 21 is the angle between the tangent at the end of the first bending segment 21 and the second direction Y. The first bending segment 21 has two ends, and the angle between the tangent at both ends of the first bending segment 21 and the second direction Y is the bending angle R1 of the first bending segment 21.

[0068] When the bending angle R1 of the first bending segment 21 is too small and less than 15°, the degree to which the first bending segment 21 bends towards the second reinforcing rib 3 is small. When the load is transferred to the side of the first bending segment 21 near the second reinforcing rib 3, the direction of the load tilts towards the second reinforcing rib 3 less. When the load is decomposed into the first lateral component F1 and the first longitudinal component, the first lateral component F1 is small and the first longitudinal component is large. Therefore, only the smaller first lateral component F1 can be borne by the second reinforcing rib 3, while the first reinforcing rib 2 still bears the larger first longitudinal component, resulting in a small improvement in the load-bearing capacity of the first reinforcing rib 2.

[0069] When the bending angle R1 of the first bending segment 21 is too large and exceeds 30°, the first bending segment 21 bends more towards the second reinforcing rib 3. When the load is transferred to the side of the first bending segment 21 near the second reinforcing rib 3, the load direction tilts more towards the second reinforcing rib 3. When the load is decomposed into the first lateral component F1 and the first longitudinal component, the first lateral component F1 is larger and the first longitudinal component is smaller. Although the longitudinal load borne by the first reinforcing rib 2 is greatly reduced, the first lateral component F1 is larger, which easily leads to the second reinforcing rib 3 being unable to bear the first lateral component F1, causing the first bending segment 21 to deform laterally and lose its load-bearing capacity.

[0070] When the bending angle R1 of the first bending segment 21 is within the range of 15° to 30°, the degree to which the first bending segment 21 bends towards the second reinforcing rib 3 is moderate. When the load is transferred to the side of the first bending segment 21 near the second reinforcing rib 3, the direction of the load tilts towards the second reinforcing rib 3 to a moderate degree. When the load is decomposed into a first lateral component F1 and a first longitudinal component, not only is the load-bearing capacity of the first reinforcing rib 2 significantly improved, but the second reinforcing rib 3 can also withstand the first lateral component F1.

[0071] Alternatively, the bending angle R2 of the second bending segment 31 is in the range of 15° to 30°, such as 15°, 20° or 30°.

[0072] like Figure 4 As shown, the bending angle R2 of the second bending segment 31 is the angle between the tangent at the end of the second bending segment 31 and the second direction Y. The second bending segment 31 has two ends, and the angle between the tangent at both ends of the second bending segment 31 and the second direction Y is the bending angle R2 of the second bending segment 31.

[0073] When the bending angle R2 of the second bending segment 31 is too small and less than 15°, the degree to which the second bending segment 31 bends towards the first reinforcing rib 2 is small. When the load is transferred to the side of the second bending segment 31 near the first reinforcing rib 2, the direction of the load tilts towards the first reinforcing rib 2 less. When the load is decomposed into the second lateral component F2 and the second longitudinal component, the second lateral component F2 is small and the second longitudinal component is large. Therefore, only the smaller second lateral component F2 can be borne by the first reinforcing rib 2, while the second reinforcing rib 3 still bears the larger second longitudinal component. The improvement of the load-bearing performance of the second reinforcing rib 3 is small.

[0074] When the bending angle R2 of the second bending segment 31 is too large and exceeds 30°, the second bending segment 31 bends more towards the first reinforcing rib 2. When the load is transferred to the side of the second bending segment 31 near the first reinforcing rib 2, the load direction tilts more towards the first reinforcing rib 2. When the load is decomposed into the second lateral component F2 and the second longitudinal component, the second lateral component F2 is larger and the second longitudinal component is smaller. Although the longitudinal load borne by the second reinforcing rib 3 is greatly reduced, the second lateral component F2 is larger, which can easily cause the first reinforcing rib 2 to be unable to bear the second lateral component F2, resulting in the second bending segment 31 deforming laterally and losing its load-bearing capacity.

[0075] When the bending angle R2 of the second bending segment 31 is within the range of 15° to 30°, the degree to which the second bending segment 31 bends towards the first reinforcing rib 2 is moderate. When the load is transferred to the side of the second bending segment 31 near the first reinforcing rib 2, the direction of the load tilts towards the first reinforcing rib 2 to a moderate degree. When the load is decomposed into the second lateral component F2 and the second longitudinal component, not only is the load-bearing capacity of the second reinforcing rib 3 greatly improved, but the first reinforcing rib 2 can also withstand the second lateral component F2.

[0076] Alternatively, the bending angle R1 of the first bending segment 21 and the bending angle R2 of the second bending segment 31 are both within the range of 15° to 30°.

[0077] In one embodiment, such as Figure 1 and Figure 2As shown, the load-bearing beam also includes a first connecting section 7 and a second connecting section 8. The first connecting section 7 is fitted to the first inner wall 101, and the second connecting section 8 is fitted to the second inner wall 102. A first reinforcing rib 2 is connected between the first connecting section 7 and the second connecting section 8. Thus, the first reinforcing rib 2 is connected to the first inner wall 101 via the first connecting section 7 and to the second inner wall 102 via the second connecting section 8. Because the first connecting section 7 is fitted to the first inner wall 101, the contact area between the first connecting section 7 and the first inner wall 101 is larger, making the support of the first reinforcing rib 2 for the first inner wall 101 more stable and reliable. Similarly, because the second connecting section 8 is fitted to the second inner wall 102, the contact area between the second connecting section 8 and the second inner wall 102 is larger, making the support of the first reinforcing rib 2 for the second inner wall 102 more stable and reliable.

[0078] After the first connecting segment 7 is attached to the first inner wall 101, it can be connected by welding. After the second connecting segment 8 is attached to the second inner wall 102, it can be connected by welding.

[0079] The first connecting segment 7 and the second connecting segment 8 can be perpendicular to the first reinforcing rib 2 to form a U-shaped structure. At this time, the first reinforcing rib 2 can be set as a channel steel.

[0080] The first connecting segment 7, the first reinforcing rib 2, and the second connecting segment 8 can be connected as one unit.

[0081] Alternatively, the load-bearing beam may also include a third connecting segment 9 and a fourth connecting segment 10. The third connecting segment 9 is fitted to the first inner wall 101, and the fourth connecting segment 10 is fitted to the second inner wall 102. A second reinforcing rib 3 is connected between the third connecting segment 9 and the fourth connecting segment 10. Thus, the second reinforcing rib 3 is connected to the first inner wall 101 via the third connecting segment 9 and to the second inner wall 102 via the fourth connecting segment 10. Because the third connecting segment 9 is fitted to the first inner wall 101, the contact area between the third connecting segment 9 and the first inner wall 101 is larger, thereby making the support of the second reinforcing rib 3 for the first inner wall 101 more stable and reliable. Similarly, because the fourth connecting segment 10 is fitted to the second inner wall 102, the contact area between the fourth connecting segment 10 and the second inner wall 102 is larger, thereby making the support of the second reinforcing rib 3 for the second inner wall 102 more stable and reliable.

[0082] After the third connecting segment 9 is attached to the first inner wall 101, it can be connected by welding. After the fourth connecting segment 10 is attached to the second inner wall 102, it can be connected by welding.

[0083] The third connecting segment 9 and the fourth connecting segment 10 can be perpendicular to the second reinforcing rib 3 to form a U-shaped structure. At this time, the second reinforcing rib 3 can be set as a channel steel.

[0084] The third connecting segment 9, the second reinforcing rib 3, and the fourth connecting segment 10 can be connected as one unit.

[0085] Alternatively, based on the first reinforcing rib 2 including the first connecting segment 7 and the second connecting segment 8, the second reinforcing rib 3 includes the third connecting segment 9 and the fourth connecting segment 10.

[0086] In one embodiment, such as Figure 1 and Figure 2 As shown, the main body 1 of the load-bearing beam includes a first U-shaped beam 11 and a second U-shaped beam 12. The first U-shaped beam 11 is slightly larger than the second U-shaped beam 12. After aligning the opening directions of the first U-shaped beam 11 and the second U-shaped beam 12, the second U-shaped beam 12 is inserted into the first U-shaped beam 11, and both sides of the second U-shaped beam 12 are connected to the inner wall of the first U-shaped beam 11. At this time, the first U-shaped beam 11 and the second U-shaped beam 12 combine to form the main body 1 of the load-bearing beam, and the first U-shaped beam 11 and the second U-shaped beam 12 enclose an inner hole.

[0087] This design offers greater load-bearing capacity and lower manufacturing costs compared to a square tube structure.

[0088] According to embodiments of this application, another aspect also provides a container, such as... Figures 5 to 7 As shown, the container includes crossbeams 4, longitudinal beams 5, and vertical beams 6 connected to each other to form a frame, wherein the crossbeams 4 are configured as any of the above load-bearing beams. This allows the crossbeams 4 of the container to have a reduced wall thickness and thus reduce weight while meeting load-bearing requirements, thereby reducing the overall weight of the container.

[0089] According to an embodiment of this application, in another aspect, an energy storage box is also provided, including an outer casing and a battery module disposed within the outer casing.

[0090] The outer casing can include any of the load-bearing beams mentioned above, or it can be configured as a container as described above. This allows for a reduction in the weight of the energy storage container while still meeting load-bearing requirements.

[0091] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by this application.
