Description

Technical Field

[0001] This application relates to the field of energy storage equipment technology, specifically to a support frame and an energy storage box. Background Technology

[0002] An energy storage container is an energy storage device that integrates core equipment such as battery packs, battery management systems (BMS), power conversion systems (PCS), thermal management systems, and fire suppression systems into a single container, enabling the storage and flexible dispatch of electrical energy. The energy storage container includes a support frame and vertical beams. The support frame is located at the bottom of the container, and the battery packs are connected to the vertical beams. The support frame also includes horizontal beams, with the vertical beams connected to the top of the horizontal beams, thus transferring the weight of the battery packs to the support frame via the vertical beams.

[0003] Since the support frame relies solely on the crossbeams to support the weight of the battery pack, its load-bearing capacity is poor. Prolonged use may cause severe deformation of the support frame, which in turn leads to damage to the paint and accelerated corrosion.

[0004] Therefore, how to solve or improve the problem of poor support capacity of energy storage box support frames in related technologies 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 support frame and an energy storage box to solve the problem that the support frame of the energy storage box has poor capacity to support the battery pack in the related art.

In the second direction, the first connection point is closer to the bearing surface than the second connection point.

[0007] In one alternative embodiment, the connecting beam is inclined relative to the third direction toward the second direction, and the inclination angle is configured to be between 5 and 30 degrees.

[0008] In one optional implementation, the cross-sectional area A of the first beam and the cross-sectional area B of the connecting beam satisfy: 2≤A / B≤5; And / or, the cross-sectional area C of the second beam and the cross-sectional area B of the connecting beam satisfy: 2≤C / B≤5.

[0009] In one optional embodiment, the first beam and the second beam are arranged in multiple intervals along the third direction, and the second beam is arranged between two adjacent first beams. A connecting beam is arranged between each adjacent first beam and second beam, and each connecting beam forms a wave shape in the third direction.

[0010] In one alternative embodiment, the portion of the bearing surface used to support the vertical beam is located at the crest of the wave.

[0011] In an optional embodiment, it further includes a first side beam and a second side beam, the first side beam and the second side beam being spaced apart along the first direction, and both the first side beam and the second side beam extending along the third direction; the two ends of the first beam and the second beam are respectively connected to the first side beam and the second side beam.

[0012] In one optional embodiment, the first side beam is provided with a first extension edge on the side near the second side beam, the side of the first beam away from the bearing surface abuts against the first extension edge, and the side of the second beam away from the bearing surface in a second direction abuts against the first extension edge. And / or, the second side beam is provided with a second extension edge on the side near the first side beam, the side of the first beam away from the bearing surface abuts against the second extension edge, and the side of the second beam away from the bearing surface in a second direction abuts against the second extension edge.

[0013] In one optional embodiment, a plurality of connecting beams are provided between the first beam and the second beam, and each of the connecting beams is arranged sequentially along a first direction.

[0014] In one alternative embodiment, each of the connecting beams is inclined toward the first direction relative to the third direction, and adjacent connecting beams are inclined in opposite directions.

[0015] Secondly, this application also provides an energy storage box, comprising: A container, comprising vertical beams and any of the support frames described above, wherein the vertical beams extend along the second direction and are connected to the bearing surface on the first beam body; The battery pack is connected to the vertical beam.

[0016] In one alternative embodiment, the connecting beam and the vertical beam are arranged adjacent to each other on the third-direction side.

[0017] In one optional embodiment, multiple connecting beams and vertical beams are provided on the first beam body along the first direction. The number of connecting beams and vertical beams is the same, and the connecting beams are arranged adjacent to the vertical beams on the side of the third direction in a one-to-one correspondence.

[0019] This application provides a support frame including a first beam, a second beam, and a connecting beam. The first beam extends along a first direction and has a bearing surface in a second direction. The second beam extends along the first direction and is spaced apart from the first beam along a third direction. The connecting beam has a first end connected to a first connection point on the first beam and a second end connected to a second connection point on the second beam. Because the distance between the first connection point and the bearing surface is smaller than the distance between the second connection point and the bearing surface in the second direction, the load transmitted from the first beam to the connecting beam generates not only a component force along the third direction but also a component force along the second direction. Therefore, the connecting beam can also bear a portion of the load along the second direction on the first beam and transfer it to the second beam for bearing. When the vertical beam carrying the battery pack is arranged along the second direction and connected to the bearing surface, the bearing surface of the first beam bears the vertical beam along the second direction. After the weight of the battery pack and the vertical beam is borne by the first beam along the second direction, part of the load is borne by the connecting beam and transferred to the second beam, thereby enhancing the first beam's ability to bear the battery pack and the vertical beam.

[0023] 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.

[0024] The following is combined with Figures 1 to 7 This describes an embodiment of the present application.

[0025] According to embodiments of this application, in one aspect, a support frame is provided, such as... Figure 1 As shown, the structure includes a first beam 1, a second beam 2, and a connecting beam 3. The first beam 1 extends along a first direction X and has a bearing surface 11 in a second direction Y, which supports the vertical beam 6. The second beam 2 extends along the first direction X and is spaced apart from the first beam 1 in a third direction Z. The first end of the connecting beam 3 is connected to a first connection point on the first beam 1, and the second end of the connecting beam 3 is connected to a second connection point on the second beam 2. In the second direction Y, the first connection point is closer to the bearing surface 11 than the second connection point; that is, in the second direction Y, the distance between the first connection point and the bearing surface 11 is less than the distance between the second connection point and the bearing surface 11. The connecting beam 3 is inclined relative to the third direction Z.

[0026] Since the first beam 1 is connected to the second beam 2 via the connecting beam 3, part of the load borne by the first beam 1 is transferred to the connecting beam 3 and then to the second beam 2. Because the distance between the first connection point and the bearing surface 11 in the second direction Y is less than the distance between the second connection point and the bearing surface 11, the load transferred from the first beam 1 to the connecting beam 3 generates not only a component force along the third direction Z but also a component force along the second direction Y. Therefore, the connecting beam 3 can bear not only the load of the upper part of the first beam 1 along the third direction Z but also the load of the upper part of the first beam 1 along the second direction Y, and transfer it to the second beam 2 for bearing. Thus, with the auxiliary bearing capacity of the connecting beam 3 and the second beam 2, the bearing capacity of the first beam 1 in both the second direction Y and the third direction Z is enhanced.

[0027] Specifically, the support frame is located at the bottom of the energy storage box, and the vertical beam 6 supporting the battery pack is arranged along the second direction Y and connected to the bearing surface 11, so that the bearing surface 11 of the first beam 1 supports the vertical beam 6 along the second direction Y. After the weight of the battery pack and the vertical beam 6 is supported by the first beam 1 along the second direction Y, part of the weight of the battery pack and the vertical beam 6 is supported by the connecting beam 3 and transferred to the second beam 2, so that the connecting beam 3 and the second beam 2 can enhance the ability of the first beam 1 to support the battery pack and the vertical beam 6.

[0028] This enhances the deformation resistance of the first beam 1 and increases its service life.

[0029] The first beam 1 can be a square beam, the connecting beam 3, and the second beam 2 can be a square beam or other types of beams.

[0030] In one embodiment, such as Figure 2 As shown, the connecting beam 3 is inclined relative to the third direction Z in the second direction Y, and the angle between the connecting beam 3 and the third direction Z is configured to be between 5 degrees and 30 degrees. It can be 5 degrees, 20 degrees or 30 degrees.

[0031] When the angle between the connecting beam 3 and the third direction Z is less than 5 degrees, the inclination of the connecting beam 3 relative to the third direction Z towards the second direction Y is small, which makes the component force along the second direction Y generated by the load transmitted from the first beam 1 to the connecting beam 3 small, and thus the enhancement effect on the bearing capacity of the first beam 1 along the second direction Y is poor.

[0032] When the angle between the connecting beam 3 and the third direction Z is greater than 30 degrees, the inclination of the connecting beam 3 relative to the third direction Z towards the second direction Y is relatively large. This results in a larger component of the load transmitted from the first beam 1 to the connecting beam 3 along the second direction Y. Although this can enhance the load-bearing capacity of the first beam 1 along the second direction Y to a greater extent, it also leads to a smaller component of the load transmitted from the first beam 1 to the connecting beam 3 along the third direction Z. In other words, the auxiliary support capacity of the connecting beam 3 for the first beam 1 along the third direction Z is poor, making the first beam 1 more prone to deformation along the third direction Z.

[0033] When the angle between the connecting beam 3 and the third direction Z is between 5 degrees and 30 degrees, it can not only ensure that the connecting beam 3 effectively supports the first beam 1 in the third direction Z, but also greatly enhance the load-bearing capacity of the first beam 1 in the second direction Y, that is, greatly enhance the ability of the first beam 1 to bear the battery pack and the vertical beam 6.

[0034] In one embodiment, the relationship between the cross-sectional area A of the first beam 1 and the cross-sectional area B of the connecting beam 3 satisfies: 2≤A / B≤5.

[0035] The ratio between the cross-sectional area A of the first beam 1 and the cross-sectional area B of the connecting beam 3 can be 2, 3, or 5.

[0036] When the ratio between the cross-sectional area A of the first beam 1 and the cross-sectional area B of the connecting beam 3 is less than 2, the cross-sectional area B of the connecting beam 3 is too large. However, the actual auxiliary support function of the connecting beam 3 for the first beam 1 is limited. The excessive cross-sectional area leads to the over-performance of the connecting beam 3, resulting in waste and excessively high usage costs.

[0037] When the ratio of the cross-sectional area A of the first beam 1 to the cross-sectional area B of the connecting beam 3 is less than 5, the cross-sectional area B of the connecting beam 3 is too small, resulting in poor load-bearing capacity and thus poor auxiliary support for the first beam 1. The connecting beam 3 is also more prone to damage and has a shorter service life.

[0038] In one embodiment, the relationship between the cross-sectional area C of the second beam 2 and the cross-sectional area B of the connecting beam 3 satisfies: 2≤C / B≤5.

[0039] The ratio between the cross-sectional area C of the second beam 2 and the cross-sectional area B of the connecting beam 3 can be 2, 3 or 5.

[0040] When the ratio between the cross-sectional area C of the second beam 2 and the cross-sectional area B of the connecting beam 3 is less than 2, the cross-sectional area C of the second beam 2 is too small, resulting in poor load-bearing capacity of the second beam 2 for the connecting beam 3. Even if the connecting beam 3 itself has sufficient performance to provide good auxiliary support for the first beam 1, due to the poor load-bearing capacity of the second beam 2, the connecting beam 3 will still fail to provide effective auxiliary support for the first beam 1 due to the failure of the force-bearing point, thus resulting in a poor enhancement effect on the load-bearing capacity of the first beam 1 along the second direction Y.

[0041] When the ratio between the cross-sectional area C of the second beam 2 and the cross-sectional area B of the connecting beam 3 is greater than 5, the cross-sectional area B of the second beam 2 is too large. The auxiliary support function of the first beam 1 still actually depends on the cross-sectional area B of the connecting beam 3, resulting in the overperformance of the second beam 2 and waste, and excessive use cost.

[0042] In one embodiment, the relationship between the cross-sectional area A of the first beam 1 and the cross-sectional area B of the connecting beam 3, and the relationship between the cross-sectional area C of the second beam 2 and the cross-sectional area B of the connecting beam 3, satisfy the following: 2≤A / B≤5; 2≤C / B≤5.

[0043] In one embodiment, such as Figures 2 to 4 As shown, multiple first beams 1 are spaced apart along the third direction Z, and each first beam 1 can support the battery pack and the vertical beam 6. Multiple second beams 2 are spaced apart along the third direction Z, and a second beam 2 is arranged between two adjacent first beams 1 in the third direction Z.

[0044] A connecting beam 3 is provided between each adjacent first beam 1 and second beam 2. For any second beam 2, it has a first side and a second side in the third direction Z. A first beam 1 is provided on each side of the second beam 2. A second connection is provided on the first side and the second side of the second beam 2. That is, the first side and the second side of the second beam 2 are respectively connected to a first beam 1 through the connecting beam 3. Thus, the two sides of the second beam 2 can respectively bear part of the load borne by the first beam 1. This not only enables the second beam 2 to simultaneously provide auxiliary load for the two first beams 1, but also makes the load borne by the two sides of the second beam 2 symmetrical, the force is more stable, and the second beam 2 is prevented from deforming along the third direction Z due to auxiliary load.

[0045] On the third direction Z, adjacent first beams 1 and second beams 2 are connected by connecting beams 3, so that multiple first beams 1 and multiple second beams 2 are connected into one unit in sequence by connecting beams 3, resulting in higher overall structural strength and stronger load-bearing capacity.

[0046] In the third direction Z, for a first beam 1 with second beams 2 on both sides, it has a first side and a second side in the third direction Z. Both the first and second sides of the first beam 1 have a first connection point, meaning that the first and second sides of the first beam 1 are respectively connected to a second beam 2 via connecting beams 3. This allows the load on both sides of the first beam 1 to be distributed to a second beam 2, and the two second beams 2 simultaneously share the load for the first beam 1, making the load-bearing capacity of the first beam 1 stronger. At the same time, the first beam 1 distributes the load to both sides simultaneously, making the stress on the first beam 1 more uniform, reducing the lateral force on the first beam 1, and thus reducing the lateral deformation of the first beam 1.

[0047] Furthermore, for each first beam 1, the connecting beams 3 on both sides in the third direction Z are inclined towards the bearing surface 11 in the direction towards the first beam 1 along the third direction Z. For each second beam 2, the connecting beams 3 on both sides in the third direction Z are inclined away from the bearing surface 11 in the direction towards the second beam 2 along the third direction Z. This results in each connecting beam 3 forming a wave-like shape in the third direction Z, thus enhancing the overall load-bearing capacity.

[0048] In one embodiment, such as Figure 7 As shown, the portion of the bearing surface 11 used to support the vertical beam 6 is located at the crest of the wave.

[0049] The vertical beam 6, which carries the battery pack, is positioned along the second direction Y and connected to the bearing surface 11. The vertical beam 6 is located at the crest of the wave. The load transmitted from the vertical beam 6 to the bearing surface 11 is then transferred via the connecting beam 3 to the trough of the wave, and finally to the second beam 2, where it is borne by the second beam 2. This provides better auxiliary bearing capacity for the vertical beam 6.

[0050] In one embodiment, such as Figure 3 and Figure 4 As shown, the support frame also includes a first side beam 4 and a second side beam 5. The first side beam 4 and the second side beam 5 are spaced apart along a first direction X, and both the first side beam 4 and the second side beam 5 extend along a third direction Z.

[0051] The first beam 1 and the second beam 2 are connected at both ends to the first side beam 4 and the second side beam 5, respectively. That is, the first end of the first beam 1 is connected to the first side beam 4, and the second end of the first beam 1 is connected to the second side beam 5; the first end of the second beam 2 is connected to the first side beam 4, and the second end of the second beam 2 is connected to the second side beam 5.

[0052] This configuration allows the first side beam 4 and the second side beam 5 to support the first beam 1 and the second beam 2 respectively, enhancing the load-bearing capacity of the first beam 1. Furthermore, the first side beam 4 connects the first beam 1 and the second beam 2 into a single unit, forming a frame structure. This strengthens the connection between the first beam 1 and the second beam 2, further enhancing the load-bearing capacity of the first beam 1.

[0053] In some embodiments, when multiple first beams 1 and second beams 2 are provided along a third direction Z, the first end of each first beam 1 is connected to the first side beam 4, and the second end of each first beam 1 is connected to the second side beam 5; the first end of each second beam 2 is connected to the first side beam 4, and the second end of each second beam 2 is connected to the second side beam 5.

[0054] In this way, the first side beam 4 and the second side beam 5 can respectively support each first beam 1 and each second beam 2. Moreover, the first side beam 4 connects each first beam 1 and each second beam 2 into one unit, forming a frame structure, which enhances the connection strength of the first beam 1 and the second beam 2, and further enhances the load-bearing capacity of each first beam 1.

[0055] In one embodiment, such as Figure 3 and Figure 4 As shown, the first side beam 4 is provided with a first extension edge 41 on the side near the second side beam 5. The side of the first beam 1 away from the bearing surface 11 abuts against the first extension edge 41, and the side of the second beam 2 away from the bearing surface 11 in the second direction Y abuts against the first extension edge 41.

[0056] Specifically, the first end of the first beam 1 is connected to the first side beam 4, and the side of the first end of the first beam 1 away from the bearing surface 11 abuts against the first extension edge 41 along the second direction Y. The first end of the second beam 2 is connected to the first side beam 4, and the side of the second beam 2 away from the bearing surface 11 abuts against the first extension edge 41 along the second direction Y. Thus, not only can the first side beam 4 be connected to the first end of the first beam 1 and the first end of the second beam 2 respectively to enhance the load-bearing capacity of the first beam 1, but the first extension edge 41 can also support the first end of the first beam 1 and the first end of the second beam 2, further enhancing the load-bearing capacity of the first beam 1.

[0057] In one embodiment, such as Figure 4 and Figure 5 As shown, the second side beam 5 is provided with a second extension edge 51 on the side close to the first side beam 4. The side of the first beam 1 away from the bearing surface 11 abuts against the second extension edge 51, and the side of the second beam 2 away from the bearing surface 11 in the second direction Y abuts against the second extension edge 51.

[0058] Specifically, the second end of the first beam 1 is connected to the second side beam 5, and the side of the second end of the first beam 1 away from the bearing surface 11 abuts against the second extension edge 51 along the second direction Y. The second end of the second beam 2 is also connected to the second side beam 5, and the side of the second beam 2 away from the bearing surface 11 abuts against the second extension edge 51 along the second direction Y. Thus, not only can the second side beam 5 be connected to the second ends of the first beam 1 and the second ends of the second beam 2 respectively, thereby enhancing the load-bearing capacity of the first beam 1, but the first extension edge 41 can also support the second ends of the first beam 1 and the second ends of the second beam 2, further enhancing the load-bearing capacity of the first beam 1.

[0059] In one embodiment, such as Figure 4 and Figure 5 As shown, the first side beam 4 has a first extension edge 41 on the side near the second side beam 5, and the second side beam 5 has a second extension edge 51 on the side near the first side beam 4.

[0060] In one embodiment, such as Figure 3 and Figure 4 As shown, multiple connecting beams 3 are provided between the first beam 1 and the second beam 2, and each connecting beam 3 is arranged sequentially along the first direction X.

[0061] Specifically, the first beam 1 has multiple first connection points along the first direction X on one side, and the first end of each connecting beam 3 is connected to the first connection point in a corresponding manner. The second beam 2 has multiple second connection points along the first direction X on one side, and the second end of each connecting beam 3 is connected to the second connection point in a corresponding manner.

[0062] Thus, multiple first beams 1 transmit loads between the first beam 1 and the second beam 2, further enhancing the load-bearing capacity of the first beam 1.

[0063] In one embodiment, such as Figure 5 As shown, each connecting beam 3 is inclined relative to the third direction Z to the second direction Y, so that the connecting beam 3 can provide a certain support for the first beam 1 in the first direction X.

[0064] The two adjacent connecting beams 3 are inclined in opposite directions. The two adjacent connecting beams 3 are connected to the first beam 1 and the second beam 2 in a trapezoidal shape, making the overall structure more stable and stronger in resistance to deformation.

[0065] In some embodiments, the angle between the connecting beam 3 and the first direction X is configured to be 60 degrees to 80 degrees. It can be 60 degrees, 70 degrees or 80 degrees.

[0066] When the angle between the connecting beam 3 and the first direction X is greater than 80 degrees, the connecting beam 3 is tilted too much relative to the first direction X, resulting in poor support capacity of the connecting beam 3 for the first beam 1 in the first direction X.

[0067] When the angle between the connecting beam 3 and the first direction X is less than 60 degrees, the connecting beam 3 is too inclined relative to the first direction X. Although the connecting beam 3 provides good support for the first beam 1 in the first direction X, the connecting beam 3 provides poor support for the first beam 1 in the third direction Z, which makes the first beam 1 prone to deformation along the third direction Z.

[0068] When the angle between the connecting beam 3 and the first direction X is between 5 degrees and 30 degrees, it can not only ensure that the connecting beam 3 effectively supports the first beam 1 in the third direction Z, but also greatly enhance the supporting capacity of the connecting beam 3 for the first beam 1 in the first direction X.

[0069] According to embodiments of this application, another aspect also provides an energy storage box, such as... Figure 7 As shown, it includes a container and a battery pack. The container includes a vertical beam 6 and any of the above support frames. The vertical beam 6 extends along the second direction Y and is connected to the bearing surface 11 of the first beam 1. The battery pack is connected to the bearing surface 11.

[0070] The bearing surface 11 of the first beam 1 bears the vertical beam 6 along the second direction Y. After the weight of the battery pack and the vertical beam 6 is borne by the first beam 1 along the second direction Y, part of the weight of the battery pack and the vertical beam 6 is borne by the connecting beam 3 and transferred to the second beam 2, thereby the connecting beam 3 and the second beam 2 can enhance the ability of the first beam 1 to bear the battery pack and the vertical beam 6.

[0071] In one embodiment, such as Figure 7 As shown, in the third direction Z, the side of the vertical beam 6 is adjacent to the connecting beam 3, that is, the first connection of the first beam body 1 is adjacent to the side of the vertical beam 6 in the third direction Z.

[0072] With this configuration, after the weight of the battery pack and vertical beam 6 acts on the bearing surface 11 of the first beam 1, a portion of the load can be directly distributed to the connecting beam 3. This reduces the load transmission path on the first beam 1, thereby lowering the bearing pressure on the first beam 1.

[0073] In one embodiment, such as Figure 7 As shown, multiple connecting beams 3 and vertical beams 6 are arranged along the first direction X on the first beam 1. The number of connecting beams 3 and vertical beams 6 is the same, and the connecting beams 3 are arranged adjacent to the side of the vertical beam 6 in the third direction Z. That is, multiple first connection points are provided on one side of each first beam 1, and each first connection point is adjacent to the side of a vertical beam 6 in the third direction Z.

[0074] With this configuration, each vertical beam 6 can support a battery pack, increasing the number of battery packs that can be installed. Moreover, after the weight of each vertical beam 6 and the battery pack acts on the bearing surface 11 of the first beam 1, a portion of the load can be directly distributed to the connecting beam 3, thereby reducing the load transmission path generated by each vertical beam 6 and lowering the bearing pressure on the first beam 1.

[0075] In one embodiment, such as Figure 6 As shown, the energy storage box also includes a lower skin 7, which covers both sides of the support frame in the second direction Y, and the lower skin 7 is connected to the second beam 2.

[0076] With this configuration, the second beam 2 serves as the support beam for the lower skin 7. This allows the support beam for the lower skin 7 to not only fix the lower skin 7 but also assist the first beam 1 in bearing load through the connecting beam 3.

[0077] That is, the original support beam used to support and fix the lower skin 7 is used as the second beam 2, which saves the installation cost.

[0078] 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.
