DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; and "inside" and "outside" refer to the outline of the device.

[0033] Figure 1 This is a front view of the energy storage container frame provided in an embodiment of the present application. Figure 2 yes Figure 1 The enlarged structural diagram of part A is shown. Figure 3 This is a schematic diagram of a first connection surface of a corner piece of an energy storage container frame provided in an embodiment of the present application.

[0034] Please also refer to Figures 1 to 3An embodiment of the present application provides an energy storage container frame, comprising a corner post 1, a crossbeam 2, and a corner fitting 3. In some embodiments, the crossbeam 2 has a first connection portion 21 at its end; the corner fitting 3 has a first connection surface 31, which includes a first connection region 311 and a second connection region 312. The first connection portion 21 is connected to the first connection region 311, and the corner post 1 is connected to the second connection region 312. The first connection region 311 is smaller than the second connection region 312.

[0035] It is understood that when stacked, the weight of the energy storage containers is transferred from the corner fittings 3 to the underlying containers or the ground. Since the corner posts 1 are connected to the corner fittings 3 in the direction of gravity, the corner posts 1 are also related to the load-bearing strength of the energy storage containers. Therefore, to increase the load-bearing strength of the energy storage containers, the corner posts 1 can be adjusted. In this embodiment, the corner posts 1 are connected to the first connection surface 31 of the corner fitting 3 at a second connection area 312. The second connection area 312 is larger than the first connection area 311. This differs from the prior art arrangement in which the area of ​​the corner fitting 3 used to connect to the corner post 1 and the area used to connect to the crossbeam 2 are substantially the same. By increasing the area of ​​the area of ​​the corner fitting 3 used to connect to the corner post 1 (i.e., by making the second connection area 312 larger than the first connection area 311), the present invention increases the portion of the corner post 1 involved in load-bearing, thereby improving the load-bearing strength of the energy storage containers and thereby resolving the technical issue of energy storage containers failing to meet stacking strength requirements due to their poor load-bearing strength.

[0036] See also Figure 3 In some embodiments, a first connection region 311 and a second connection region 312 are sequentially provided along the length of the crossbeam 2, and the first connection region 311 and the second connection region 312 are connected. Furthermore, along the length of the crossbeam 2, the sum of the lengths of the first connection region 311 and the second connection region 312 is equal to the length of the first connection surface 31. This allows the first connection surface 31 of the corner piece 3 to be utilized as much as possible along the length of the crossbeam 2, thereby maximizing the load-bearing strength of the energy storage container.

[0037] In some embodiments, the second connection region 312 of the corner piece 3 accounts for 70% to 80% of the area of ​​the first connection surface 31 .

[0038] It should be noted that energy storage containers require not only load-bearing strength but also lifting strength. Therefore, when determining the area of ​​the area where the corner piece 3 connects to the corner post 1 (i.e., the second connection area 312), both load-bearing strength and lifting strength must be taken into consideration. Otherwise, the load-bearing strength may meet the requirements but the lifting strength may be insufficient, resulting in a situation where the container cannot be lifted. This application sets the area of ​​the second connection area 312 connected to the corner post 1 to 70% to 80% of the first connection surface 31. This not only maximizes the load-bearing strength of the energy storage container, but also helps ensure the lifting strength of the container. The specific area ratio of the second connection area 312 to the first connection surface 31 can be determined based on the actual load-bearing strength requirements. For example, if the energy storage container has a high load-bearing strength requirement, the area ratio of the second connection area 312 to the first connection surface 31 can be set to 80%. If the energy storage container has a relatively low load-bearing strength requirement, the area ratio of the second connection area 312 to the first connection surface 31 can be set to 70%.

[0039] In some embodiments, the area ratio of the first connection region 311 to the second connection region 312 of the corner piece 3 is 1:2.5 to 1:4.

[0040] As mentioned above, the energy storage container not only has load-bearing strength requirements, but also has lifting strength requirements. When improving the load-bearing strength of the energy storage container, the lifting strength of the energy storage container should also be taken into consideration. Therefore, in the embodiment of the present application, the area ratio of the first connection area 311 and the second connection area 312 is set to 1:2.5 to 1:4, which can not only improve the load-bearing strength of the energy storage container as much as possible, but also help to ensure the lifting strength of the energy storage container. Specifically, the area ratio of the first connection area 311 to the second connection area 312 can be selected according to the actual load-bearing requirements. For example, when the load-bearing strength requirement of the energy storage container is high, the area ratio of the first connection area 311 to the second connection area 312 can be selected as 1:4. When the load-bearing strength requirement of the energy storage container is relatively low, the area ratio of the first connection area 311 to the second connection area 312 can be selected as 1:2.5.

[0041] Figure 3 : is a schematic diagram of a first connection surface of a corner piece of an energy storage container frame provided in an embodiment of the present application, Figure 4 Schematic diagram of the connection profiles of the corner columns and beams with the corner fittings provided in the embodiments of the present application. Figure 5 yes Figure 1 A top view of section A is shown.

[0042] Please also refer to Figures 3 to 5In one embodiment of the present application, the second connection area 312 and the first connection area 311 are sequentially arranged along the length direction of the energy storage container frame.

[0043] As mentioned above, while improving the load-bearing strength of the energy storage container, the lifting strength must also be considered. The lifting strength of the energy storage container is mainly related to the crossbeam 2 and the corner piece 3, specifically the area of ​​the first connection area 311 connected to the first connection portion 21 of the crossbeam 2, and the strength of the crossbeam 2 itself. Figure 5 In the front view direction of the energy storage container frame provided in the embodiment of the present application, the width of the crossbeam 2 is the same as the width of the first connecting portion 21. Therefore, in the embodiment of the present application, the second connecting area 312 and the first connecting area 311 are sequentially arranged along the length direction of the energy storage container frame (refer to Figure 3 ), so that in the front view direction of the energy storage container frame provided in the embodiment of the present application, the width of the first connecting portion 21 can be set to be the same as the width of the first connecting area 311, so that the width of the beam 2 is also the same as the width of the first connecting area 311, thereby improving the strength of the beam 2 itself, and further improving the lifting strength of the energy storage container.

[0044] Figure 2 yes Figure 1 The enlarged structural diagram of part A is shown. Figure 4 Schematic diagram of the connection profiles of the corner columns and beams with the corner fittings provided in the embodiments of the present application.

[0045] Please also refer to Figure 2 and Figure 4 In one embodiment of the present application, the corner post 1 includes a main body 11 and an extension 12, each connected to the other. The main body 11 and the extension 12 form a smooth transition at their junction. Both the main body 11 and the extension 12 are connected to the second connection region 312. The contour of the connection between the extension 12 and the second connection region 312 aligns with the contour of the connection between the first connection portion 21 and the first connection region 311. On the side of the second connection region 312 facing away from the first connection region 311, the contour of the connection between the main body 11 and the second connection region 312 is the same as the contour of the second connection region 312.

[0046] refer to Figure 4 In the present embodiment of the present application, the connection profile of the main body 11 and the second connection area 312 is the main body connection profile 110, the connection profile of the extension portion 12 and the second connection area 312 is the extension connection profile 120, the connection profile of the first connection portion 21 and the first connection area 311 of the crossbeam 2 is the first connection portion connection profile 210, and the main body connection profile 110 is connected to the extension connection profile 120, and at the same time, the extension connection profile 120 is also connected to the first connection connection profile 210. Figure 2It can be seen that the structure of the corner post 1 provided in the embodiment of the present application, as well as the positional relationship between the main body 11, the extension 12, and the connecting profile 210 of the first connecting portion, can fully utilize the first connecting surface 31 of the corner fitting 3. Not only does a larger area of ​​the first connecting surface 31 of the corner fitting 3 be used for connection with the corner post 1, but the area not connected to the corner post 1 is also fully utilized for connection with the first connecting portion 21. This not only improves the load-bearing strength of the energy storage container, but also ensures the lifting strength of the energy storage container.

[0047] In one embodiment of the present application, the corner post 1 is in contact with the first connecting portion 21 of the cross beam 2 in the length direction of the cross beam 2 .

[0048] When designing an energy storage container frame, both the load-bearing strength and the lifting strength of the energy storage container must be considered. In this embodiment, the corner posts 1 are brought into contact with the first connecting portion 21 of the crossbeam 2 along its length. This not only improves the load-bearing strength of the energy storage container, but also maximizes the length of the first connecting portion 21 of the crossbeam 2, increasing the connection area between the crossbeam 2 and the first connecting region 311, thereby improving the lifting strength of the energy storage container.

[0049] In one embodiment of the present application, a corner post 1, a corner piece 3, and a crossbeam 2 constitute a frame assembly. The energy storage container frame includes at least two frame assemblies, two of which are arranged on diagonal lines on the top side of the energy storage container frame.

[0050] As is well known, energy storage containers are often stacked, and the closer the stacked position is to the ground, the greater the weight the energy storage container bears. As mentioned above, the load-bearing capacity of the energy storage container is related to the corner fittings 3 and the corner posts 1. When designing the load-bearing strength of the energy storage container, its lifting strength also needs to be considered. Therefore, in the embodiment of the present application, a frame assembly is formed using a corner post 1, a corner fitting 3, and a crossbeam 2. A frame assembly is also provided at each end of the diagonal line of the top of the energy storage container frame. This not only improves the load-bearing strength of the energy storage container frame, but also ensures the stability of the energy storage container frame.

[0051] In one embodiment of the present application, the energy storage container frame includes four frame assemblies, the corner pieces 3 of the four frame assemblies are respectively arranged at the four top corners of the energy storage container frame, the corner columns 1 of the four frame assemblies are parallel to each other and extend in the same direction, and among the four frame assemblies, two frame assemblies arranged at intervals along the length direction of the energy storage container share a crossbeam 2.

[0052] In the embodiment of the present application, the top of the energy storage container frame includes four frame components, and the top of the energy storage container is closely related to the load-bearing strength and lifting strength of the energy storage container. Therefore, in the embodiment of the present application, frame components are provided at the four top corners of the top of the energy storage container frame to improve the load-bearing strength of the energy storage container frame.

[0053] In one embodiment of the present application, the crossbeam 2 includes an end surface 22 at its end, and the first connecting portion 21 extends from one side of the end surface 22 along the length of the crossbeam 2. The corner piece 3 also has a second connecting surface 32, and the end surface 22 is connected to the second connecting surface 32. The second connecting surface 32 and the first connecting surface 31 are adjacent surfaces.

[0054] For reference Figure 2 In the embodiment of the present application, the end face 22 of the beam 2 is connected to the second connecting face 32 of the corner piece 3, which increases the area of ​​the connecting region between the beam 2 and the corner piece 3, thereby improving the lifting strength of the energy storage container.

[0055] In one embodiment of the present application, an energy storage container frame is provided, comprising a corner post 1, a crossbeam 2, and a corner fitting 3. The crossbeam 2 has a first connection portion 21 at its end; the corner fitting 3 has a first connection surface 31, which includes a first connection region 311 and a second connection region 312. The first connection portion 21 is connected to the first connection region 311, and the corner post 1 is connected to the second connection region 312, with the first connection region 311 being smaller than the second connection region 312. Along the length of the crossbeam 2, the corner post 1 contacts the first connection portion 21 of the crossbeam 2. One corner post 1, one corner fitting 3, and one crossbeam 2 constitute a frame assembly. The energy storage container frame includes four frame assemblies, each of which has corner fittings 3 disposed at the four corners of the energy storage container frame. The corner posts 1 of the four frame assemblies are parallel to each other and extend in the same direction. Two of the four frame assemblies, spaced apart along the length of the energy storage container, share a common crossbeam 2. The crossbeam 2 includes an end surface 22 at an end thereof. The first connecting portion 21 extends from one side of the end surface 22 along the length direction of the crossbeam 2 .

[0056] In this embodiment of the present application, the area of ​​the second connection region 312 connected to the corner post 1 is set to be larger than the area of ​​the first connection region 311 connected to the first connection portion 21 of the crossbeam 2. By increasing the area of ​​the second connection region 312, the corner post 1 participates more in bearing the energy storage container's load, thereby improving the container's load-bearing strength. The top of the energy storage container frame in this embodiment of the present application includes four frame assemblies, and the first connection region 311 in each frame assembly is smaller than the second connection region 312, similarly improving the load-bearing strength of the energy storage container frame. Furthermore, along the length of the crossbeam 2, the corner post 1 contacts the first connection portion 21 of the crossbeam 2, which not only increases the load-bearing strength of the energy storage container frame but also maximizes the connection area between the first connection portion 21 of the crossbeam 2 and the first connection region 311, thereby enhancing the lifting strength of the energy storage container.

[0057] On the other hand, the present application also provides an energy storage container, which includes the above-mentioned energy storage container frame.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for those skilled in the art, based on the ideas of the present application, there may be changes in the specific implementation methods and application scope.
