Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0039] Reference Figure 1 and Figure 2 As shown, this embodiment provides a mounting bracket installation structure 1, including a housing 11, a mounting block 12 and a plurality of mounting brackets 13. The housing 11 includes at least two opposing frame beams 101, and the frame beams 101 are provided with a weight reduction cavity 102. The mounting block 12 is connected to the weight reduction cavity 102. The plurality of mounting brackets 13 are located outside the frame beams 101 and are connected to the mounting block 12.

[0040] By setting a weight-reducing cavity 102 in the side beam 101 of the box body 11 and placing the mounting block 12 in the weight-reducing cavity 102, and connecting the mounting bracket 13 to the mounting block 12, it is not necessary to process the mounting groove on the side beam 101, thus avoiding the impact on the overall strength of the side beam 101 and reducing the processing cost of the parts. Accordingly, the installation of the mounting bracket 13 can be facilitated, thereby improving the technical problems of low overall strength of the side beam 101 of the box body 11 and high processing cost of the parts.

[0041] In some embodiments, refer to Figure 1 and Figure 2 As shown, a mounting bracket installation structure 1 further includes a first connector 14, which is connected to the mounting bracket 13. One end of the first connector 14 extends into the weight-reducing cavity 102 and is connected to the mounting block 12. In this embodiment, the mounting bracket 13 is connected to the mounting block 12 via the first connector 14, eliminating the need for welding on the frame beam 101 and avoiding any impact on the overall strength of the frame beam 101 caused by welding. Furthermore, since the connection of the mounting bracket 13 does not require machining mounting grooves on the frame beam 101, the installation process is convenient and quick, allowing for more flexible adjustment of the installation position.

[0042] In this embodiment, refer to Figure 1 and Figure 2 As shown, each frame beam 101 is provided with at least five mounting brackets 13, and the five mounting brackets 13 are arranged at intervals along the axial direction of the frame to make the stress acting on the frame beam 101 more uniform, thereby reducing the possibility of deformation of the frame beam 101.

[0043] It should also be noted that, in this embodiment, reference is made to... Figure 3 As shown, the mounting block 12 is provided with a second connector 15, and the first connector 14 is connected to the second connector 15.

[0044] Specifically, the first connector 14 is a bolt, and the second connector 15 is a wire thread insert. The first connector 14 and the second connector 15 are threaded together. In other embodiments, other connectors may be selected according to actual needs.

[0045] Of course, in other embodiments, the first connector 14 may be provided with a threaded portion, the mounting block 12 may be provided with a threaded hole, and the threaded portion and the threaded hole may be threadedly connected.

[0046] In some embodiments, refer to Figure 4 As shown, the frame beam 101 is provided with a first through hole 103, which is connected to the weight reduction cavity 102; the mounting bracket 13 is provided with a second through hole 104, the diameter of which is different from that of the first through hole 103; the first connector 14 passes through the first through hole 103 and the second through hole 104 to be connected and fixed with the mounting block 12.

[0047] The first connector 14, passing through the first through hole 103 and the second through hole 104, forms a reliable connection method that effectively distributes and transmits loads, making the connection between the frame beam 101 and the mounting bracket 13 more stable. Furthermore, the different diameters of the second through hole 104 and the first through hole 103 facilitate alignment between the mounting bracket 13 and the frame beam 101, while also preventing connection failures due to tolerances between the first connector 14, the first through hole 103, and the second through hole 104, thus ensuring the assembly of the mounting bracket 13 and the frame beam 101. It is understood that in this embodiment, the mounting bracket 13 includes a first connecting surface and a second connecting surface, the first connecting surface having a second through hole 104, and the second connecting surface used to connect the first device.

[0048] It should also be further noted that, in this embodiment, reference is made to... Figure 2 As shown, there are four first connectors 14 arranged in an array. Therefore, the first connectors 14 can provide multiple connection points, thereby significantly enhancing the connection stability between the frame beam 101 and the mounting bracket 13. Furthermore, the array arrangement of the four first connectors 14 allows the stress to be evenly distributed among multiple connection points, avoiding stress concentration and better ensuring the connection between the frame beam 101 and the mounting bracket 13.

[0049] In some embodiments, refer to Figure 5 As shown, the frame beam 101 is provided with a first positioning hole 105, and the mounting block 12 is provided with a second positioning hole 121. The mounting bracket installation structure 1 also includes a positioning element 16, which passes through the first positioning hole 105 and the second positioning hole 121. By providing the first positioning hole 105 on the frame beam 101 and the second positioning hole 121 on the mounting block 12, and connecting them using the positioning element 16, high-precision positioning between the frame beam 101 and the mounting block 12 can be achieved, avoiding installation failure of the mounting block 12 due to positional deviation, and also accelerating the installation efficiency between the mounting block and the frame beam 101.

[0050] In some embodiments, refer to Figure 5 As shown, the diameter of the first positioning hole 105 is larger than the diameter of the second positioning hole 121. This avoids the possibility of the two positioning holes not being perfectly aligned due to manufacturing or installation errors. Furthermore, the larger first positioning hole 105 allows for a certain degree of positional deviation, making it easier to insert the positioning element 16. Also, because the diameter of the first positioning hole 105 is larger than the diameter of the second positioning hole 121, the position of the mounting block 12 can be fine-tuned, providing greater flexibility.

[0051] In some embodiments, refer to Figure 2 As shown, there are at least two first positioning holes 105, and each end of the frame beam 101 along the axial direction is provided with a first positioning hole 105. The provision of at least two positioning holes can prevent the mounting block 12 from rotating or shifting during installation, thereby ensuring that the mounting block 12 is fixed in position on the frame beam 101, thus improving the stability of the entire structure.

[0052] In some embodiments, refer to Figure 1 and Figure 2 As shown, the mounting block 12 extends axially along the frame beam 101, and at least two mounting blocks 12 are provided, which are spaced apart and parallel to each other. In this embodiment, the mounting block 12 extends axially along the frame beam 101 to form a strip shape, thereby acting as a reinforcing block and increasing the overall strength of the frame beam 101; furthermore, the spaced arrangement of the two mounting blocks 12 along the axial direction of the frame beam 101 provides multi-point support to ensure the connection of the mounting bracket 13 on the frame beam 101; at the same time, the spaced arrangement of the two mounting blocks 12 can also increase the bending stiffness of the frame beam 101 and improve the rigidity of the frame beam 101, thereby avoiding bending deformation of the frame beam 101.

[0053] In some embodiments, refer to Figure 3 As shown, the weight-reducing cavity 102 is provided with reinforcing ribs 17, which extend axially along the frame beam 101. The reinforcing ribs 17 divide the internal space of the frame beam 101 into multiple sub-cavities 1021, and at least two sub-cavities 1021 are provided with mounting blocks 12. In this embodiment, the strength of the frame beam 101 can be increased without adding too much weight through the reinforcing ribs 17, and the mounting blocks 12 placed in the sub-cavities 1021 can further enhance the local stability of the frame beam 101 and ensure the structural strength of the frame beam 101.

[0054] In some embodiments, the length ratio of the mounting block 12 to the side beam 101 is between 0.8 and 1. By setting the above parameters, the length of the mounting block 12 can be reasonably designed to ensure the connection between the side beam 101 and the mounting bracket 13, as well as the overall strength of the side beam 101, and to achieve a lightweight structure of the side beam 101.

[0055] In summary, when installing the mounting bracket 13, by setting the mounting block 12 in the weight-reducing cavity 102 on the side beam 101, and connecting the mounting bracket 13 to the mounting block 12 via the first connector 14, it is possible to avoid setting machining grooves on the side beam 101, reducing the production cost of parts, and also enhancing the installation flexibility of the mounting bracket 13, thereby allowing for flexible adjustment of the installation position of the mounting bracket 13 and facilitating the installation process; at the same time, since the mounting bracket 13 does not need to be connected to the side beam 101 by welding, the impact on the overall strength of the side beam 101 during the installation of the mounting bracket 13 is reduced, thus lowering production costs.

[0056] Furthermore, since the side beam 101 is provided with a weight-reducing cavity 102 and a plurality of reinforcing ribs 17 are provided in the weight-reducing cavity 102, and the mounting block 12 is placed in the sub-cavity 1021, the local stability of the side beam 101 can be further enhanced. The mounting block 12 and the reinforcing ribs 17 can also increase the strength of the side beam 101 without increasing the weight of the side beam 101 too much, ensuring the structural strength of the side beam 101, thereby reducing the possibility of deformation of the side beam 101 and extending the service life of the box 11.

[0057] Secondly, this embodiment provides a battery pack, including a mounting bracket structure 1 for multiple battery modules and a mounting structure 1. The housing 11 is provided with multiple mounting cavities 2, and each mounting cavity 2 is provided with at least one battery module.

Accordingly, the installation of the mounting bracket 13 can be facilitated, thereby improving the technical problems of low overall strength of the side beam 101 of the box body 11 and high processing cost of the parts.

[0060] In this embodiment, the housing 11 is provided with multiple partitions, which divide the internal space of the housing 11 into multiple mounting cavities 2 to facilitate the installation of the battery module.

[0061] In summary, when installing the mounting bracket 13, by setting the mounting block 12 in the weight-reducing cavity 102 on the side beam 101, and connecting the mounting bracket 13 to the mounting block 12 via the first connector 14, it is possible to avoid setting machining grooves on the side beam 101, reducing the production cost of parts, and also enhancing the installation flexibility of the mounting bracket 13, thereby allowing for flexible adjustment of the installation position of the mounting bracket 13 and facilitating the installation process; at the same time, since the mounting bracket 13 does not need to be connected to the side beam 101 by welding, the impact on the overall strength of the side beam 101 during the installation of the mounting bracket 13 is reduced, thus lowering production costs.

The mounting block 12 and the reinforcing ribs 17 can also increase the strength of the side beam 101 without increasing the weight of the side beam 101 too much, ensuring the structural strength of the side beam 101, thereby reducing the possibility of deformation of the side beam 101 and extending the service life of the box 11.
