[0018] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0019] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0020] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0021] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0022] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0023] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0024] Before transportation, the battery packs can be mounted on mounting racks. These racks can support multiple battery packs, and the racks themselves can be housed within a storage container, thus allowing for a higher energy density within the container. These mounting racks can constitute an energy storage container.

[0025] As the energy density requirements of energy storage containers increase, more battery packs need to be arranged within the limited space inside the energy storage container. This requires the size of the mounting frame to be reduced as much as possible, for example, by reducing the width of the longitudinal beams on the mounting frame to provide more installation space for the battery packs. However, this will reduce the structural strength and seismic resistance of the mounting frame, and will prevent the container carrying the mounting frame from being transported over long distances at full load.

[0026] To address the aforementioned technical problems, this application provides a mounting bracket. Figure 1 This is a schematic diagram of the structure of the mounting bracket located in the receiving device according to one embodiment of this application, as shown below. Figure 1 As shown, the mounting bracket 200 can be installed in the housing device 100. Exemplarily, the housing device 100 includes a housing 110 with a housing space inside, and the mounting bracket 200 can be entirely housed in the housing space.

[0027] The housing 110 may include a top beam 111 and a bottom beam 112, both of which can be made of H-beams. The top end of the mounting bracket 200 can be connected to the top beam 111 of the housing 110, and the bottom end of the mounting bracket 200 can be connected to the bottom beam 112 of the housing 110, thereby ensuring the stability of the mounting bracket 200 in the housing 110.

[0028] The mounting bracket 200 includes a longitudinal beam 1 and a crossbeam 2. The crossbeam 2 is connected to the longitudinal beam 1 and can be used to support the battery pack 300. The crossbeam 2 and the longitudinal beam 1 can be welded together. Multiple crossbeams 2 and multiple longitudinal beams 1 can be provided, and multiple mounting positions for mounting the battery pack 300 can be formed between the multiple crossbeams 2 and multiple longitudinal beams 1 to achieve the bearing capacity of multiple battery packs 300.

[0029] Multiple crossbeams 2 can be connected to both sides of the longitudinal beam 1, and multiple battery packs 300 can be supported on the corresponding crossbeams 2. This places high demands on the structural strength of the longitudinal beam 1. However, as the energy density requirements of the housing increase, the number of battery packs 300 also increases, and the number of battery packs 300 that the longitudinal beam 1 needs to support also increases. This makes it difficult for the structural strength of the longitudinal beam 1 to meet the requirements, especially at the connection between the longitudinal beam 1 and the housing body 110, where it is prone to breakage.

[0030] Therefore, in this embodiment, the mounting bracket 200 further includes a first reinforcing member 3. The first reinforcing member 3 is connected to the bottom end of the longitudinal beam 1 along the length direction of the longitudinal beam 1, and the end of the first reinforcing member 3 away from the longitudinal beam 1 is used to connect with the housing device. The first reinforcing member 3 is an independently manufactured component and can be independently welded to the longitudinal beam 1 of the mounting bracket 200 and the bottom beam 112 of the housing 110 of the housing device 100. The strength of the first reinforcing member 3 can be much greater than the strength of the longitudinal beam 1, and the connection strength between the longitudinal beam 1 and the bottom beam 112 of the housing 110 can be enhanced by the first reinforcing member 3.

[0031] The first reinforcing member 3 is arranged between the longitudinal beam 1 and the box 110 along the length of the longitudinal beam 1. The longitudinal beam 1 does not need to be directly connected to the box 110, thereby reducing the length of the longitudinal beam 1, reducing stress concentration, and significantly reducing the maximum stress and deformation of the longitudinal beam 1. This can significantly improve the seismic performance of the mounting bracket 200 in the box 110.

[0032] The first reinforcing member 3, the longitudinal beam 1, and the housing 110 can all be made of metal. After the first reinforcing member 3 is connected to the longitudinal beam 1 and the housing 110 respectively, an electrical connection can be formed between the longitudinal beam 1, the first reinforcing member 3, and the housing 110. The current of the battery pack 300 can be transmitted to the housing 110 along the longitudinal beam 1 and the first reinforcing member 3 to achieve grounding, ensuring the safety of the battery pack 300 during transportation or use in the housing device 100.

[0033] The longitudinal beam 1 can be a columnar structure, and the cross-sectional shape of the longitudinal beam 1 can be square, rectangular, etc. The first reinforcing member 3 can also be a columnar structure, and the cross-sectional shape of the first reinforcing member 3 can also be square, rectangular, etc. The width of the first reinforcing member 3 is greater than the width of the longitudinal beam 1, or the outline area of ​​the cross-section of the first reinforcing member 3 is greater than the outline area of ​​the cross-section of the longitudinal beam 1, so that the projection of the cross-sectional outline of the longitudinal beam 1 lies within the projection of the cross-sectional outline of the first reinforcing member 3. This improves the connection strength between the first reinforcing member 3 and the housing 110 and the longitudinal beam 1. The width of the first reinforcing member 3 refers to its dimension perpendicular to the length of the longitudinal beam 1, and the width of the longitudinal beam 1 is also a dimension perpendicular to its length.

[0034] In some embodiments, the cross-sectional shapes of the first reinforcing member 3 and the longitudinal beam 1 can also be circular, elliptical, polygonal, etc. The outline area of ​​the cross-section of the first reinforcing member 3 is larger than the outline area of ​​the cross-section of the longitudinal beam 1, thereby enhancing the connection strength between the first reinforcing member 3 and the longitudinal beam 1 and the box 110.

[0035] The first reinforcing member 3 includes a first end face and a second end face. The first end face is the end face of the first reinforcing member 3 facing the bottom beam 112, and the second end face is the end face of the first reinforcing member 3 facing the longitudinal beam. The first end face is connected to the bottom beam 112 of the receiving device 100, and the second end face is connected to the longitudinal beam 1. Both the first and second end faces can be planar. The first end face can fit against the upper surface of the bottom beam 112, and the second end face can fit against the bottom of the longitudinal beam 1. Along the length of the longitudinal beam 1, the projected area of ​​the longitudinal beam 1 on the second end face is smaller than the area of ​​the second end face. Therefore, the first reinforcing member 3 has a larger area for supporting the longitudinal beam 1, which helps to improve the reliability of the support for the longitudinal beam 1.

[0036] Figure 2 for Figure 1 The enlarged view at point A, as shown Figure 2 As shown, the longitudinal beam 1 is fixedly connected to the first reinforcing member 3 by bolts 5 and nuts 6. The first reinforcing member 3 is a hollow structure, and its side wall 31 facing the longitudinal beam 1 has a first mounting hole. The bottom of the longitudinal beam 1 has a base 11, and the base 11 has a second mounting hole that mates with the first mounting hole. Bolts 5 can pass through the second mounting hole and the first mounting hole sequentially from the side of the base 11 away from the first reinforcing member 3. Then, nuts 6 can be tightened onto bolts 5 from the side wall 31 away from the longitudinal beam 1. Thus, the longitudinal beam 1 and the first reinforcing member 3 are locked together by the cooperation of bolts 5 and nuts 6, which facilitates the assembly of the longitudinal beam 1 and the first reinforcing member 3 and ensures the reliability of the connection between the longitudinal beam 1 and the first reinforcing member 3.

[0037] The mounting bracket 200 also includes a first adjusting shim 7, which is disposed between the longitudinal beam 1 and the first reinforcing member 3. Exemplarily, the first adjusting shim 7 can be disposed between the base 11 of the longitudinal beam 1 and the side wall 31 of the first reinforcing member 3. By providing the first adjusting shim 7, the installation accuracy of the longitudinal beam 1 in the vertical direction can be adjusted.

[0038] Figure 3 This is a schematic diagram showing the cooperation between the longitudinal beam 1 and the first reinforcing member 3 in the mounting bracket 200 provided in the embodiments of this application, as shown below. Figure 3As shown, the first reinforcing member 3 is provided with a slot 32, and the first reinforcing member 3 is fixedly sleeved to the longitudinal beam 1 through the slot 32. The portion of the longitudinal beam 1 near the bottom can extend into the slot 32, and the bottom end of the longitudinal beam 1 can be fixedly connected to the bottom beam 112 of the box body 110, for example, by welding the bottom end of the longitudinal beam 1 to the bottom beam 112 of the box body 110. After the longitudinal beam 1 passes through the slot 32 of the first reinforcing member 3, the first reinforcing member 3 can be fixedly connected to the longitudinal beam 1. The first reinforcing member 3 can strengthen a portion of the length at the connection between the longitudinal beam 1 and the box body 110, preventing stress concentration at the connection between the longitudinal beam 1 and the box body 110, which could lead to breakage of the longitudinal beam 1 at the connection with the box body 110.

[0039] For example, the first reinforcing member 3 is welded and fixed to the longitudinal beam 1, thereby ensuring the reliability of the connection between the first reinforcing member 3 and the longitudinal beam 1 and ensuring the effectiveness of the structural reinforcement of the longitudinal beam 1.

[0040] Figure 4 A schematic diagram of the structure of the mounting bracket located in the receiving device according to another embodiment of this application is shown below. Figure 4 As shown, the mounting bracket 200 also includes a second reinforcing member 4. The first end of the second reinforcing member 4 is connected to the end of the longitudinal beam 1 away from the first reinforcing member 3, and the second end of the second reinforcing member 4 is used to connect to the top beam 111 of the housing 100. In this embodiment, the top end of the longitudinal beam 1 and the top beam 111 of the housing 110 do not need to be in direct contact. By connecting the second reinforcing member 4 to both the longitudinal beam 1 and the top beam 111, relative fixation between the longitudinal beam 1 and the housing 110 can be achieved. The second reinforcing member 4 can improve the strength of the longitudinal beam 1 after connection, preventing breakage of the longitudinal beam 1 near the top beam 111 when subjected to vibration.

[0041] Figure 5 for Figure 4 The enlarged view at point B, as shown Figure 5As shown, the second reinforcing member 4 includes a first structural member 41 and a second structural member 42. The first structural member 41 is configured to be connected to the longitudinal beam bolt 5 to create an adjustable gap between the longitudinal beam 1 and the receiving device 100. The second structural member 42 is welded and fixed to the receiving device 100. Specifically, the first structural member 41 and the second structural member 42 have an included angle α between them. The first structural member 41 is fixedly connected to the side of the longitudinal beam 1 by the cooperation of the longitudinal beam bolt 5 and the nut 6. The second structural member 42 is used to be welded and fixed to the top beam 111 of the housing 110. In this embodiment, the longitudinal beam bolt 5 can pass through the longitudinal beam 1 and the first structural member 41 from the side of the longitudinal beam 1 along the width direction of the longitudinal beam 1, and then the longitudinal beam 1 and the second reinforcing member 4 are fastened by the cooperation of the nut 6 and the longitudinal beam bolt 5. This facilitates the assembly of the longitudinal beam 1 and the second reinforcing member 4, and ensures the reliability of the connection between the longitudinal beam 1 and the second reinforcing member 4. The second reinforcing member 4 can be welded to the top beam 111, thereby ensuring the reliability of the fixation between the second reinforcing member 4 and the top beam 111, and thus ensuring the reliable fixation of the longitudinal beam 1 relative to the top beam 111. Therefore, in this embodiment, the second reinforcing member 4 can improve the strength of the longitudinal beam 1 after installation, preventing problems such as deformation and breakage of the longitudinal beam 1.

[0042] The second reinforcing member 4, the longitudinal beam 1, and the housing 110 can all be made of metal. After the second reinforcing member 4 is connected to the longitudinal beam 1 and the housing 110 respectively, an electrical connection can be formed between the longitudinal beam 1, the second reinforcing member 4, and the housing 110. The current of the battery pack 300 can be transmitted to the housing 110 along the longitudinal beam 1 and the second reinforcing member 4 to achieve grounding, ensuring the safety of the battery pack 300 during transportation or use in the housing device 100.

[0043] like Figure 5 As shown, the mounting bracket 200 also includes a second adjusting shim 8, which is disposed between the first structural member 41 and the side of the longitudinal beam 1. The second adjusting shim 8 allows for adjustment of the installation accuracy of the longitudinal beam 1 in the width direction.

[0044] The first adjusting shim 7 and the second adjusting shim 8 can have the same structure, and both can be metal sheet structures. By adjusting the thickness of the second adjusting shim 8, it can be ensured that the longitudinal beam 1 is vertical after installation, avoiding excessive tilting of the longitudinal beam 1.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
