[0046] The following is combined with Figures 1 to 12 The embodiments shown illustrate the technical solution of this utility model:

[0047] This utility model embodiment provides a battery module, such as Figures 1 to 4 As shown, it includes: battery bracket 1, busbar 2, fixing rod 3, battery unit 4, and connector 5;

[0048] The battery support 1 has multiple battery brackets arranged coaxially in parallel. Multiple battery mounting holes 101 are provided on the mounting surface of each battery bracket 1, and the center lines connecting adjacent battery mounting holes 101 form an equilateral triangle. The mounting surfaces of adjacent battery brackets 1 are positioned opposite each other. Multiple busbars 2 are conductive components and are respectively located on the non-mounting surfaces of the battery brackets 1. Multiple electrode springs 201 are formed on the busbars 2 and are disposed within the battery mounting holes 101. Multiple fixing rods 3 penetrate multiple battery brackets 1 and are detachably connected to the outermost battery bracket 1. Multiple battery units 4 are respectively mounted in the battery mounting holes 101. A connector 5 is detachably connected to the outermost battery bracket 1.

[0049] In some embodiments, the battery support 1 can be a triangle, rectangle or other complex geometric shape, which can realize the internal space layout of a special battery compartment or improve the structural strength of the battery module, and can install the battery unit 4.

[0050] In this embodiment, as Figure 3 As shown, the battery holder 1 has a circular structure, with the battery holders arranged coaxially and parallel to each other. Multiple battery mounting holes 101 are formed on the mounting surface of the battery holder 1. Since the center lines connecting adjacent battery mounting holes 101 form equilateral triangles, a periodic pattern of mounting holes is created using 120° symmetry. This minimizes the spacing between adjacent battery mounting holes 101, reduces wasted space at the edges of the battery holder 1, and maximizes the use of space on the battery holder 1. Figure 4 As shown, the busbar 2 is a conductive component, located between the non-mounting surfaces of the battery support 1. Multiple electrode springs 201 are formed on the busbar 2, and these multiple electrode springs 201 are disposed within the battery mounting holes 101. By welding the busbar 2 to the battery support 1, multiple battery units 4 are connected together, improving the heat dissipation performance of the battery units 4, ensuring the stable operation of the battery units 4, and improving the current utilization efficiency of the battery units 4. The fixing rod 3 connects multiple battery supports 1 through and is detachably connected to the battery support 1 at the outermost end, connecting the battery support 1, battery units 4, and busbar 2 to form a whole, realizing the modular installation of the battery module. The connector 5 is detachably connected to the battery support 1 at the outermost end, facilitating the subsequent installation of the battery module and battery compartment.

[0051] This utility model provides a battery module and an underwater pressure-bearing battery compartment. By modularly assembling the battery units 4 and using the shape of the connectors 5 to constrain the cable installation path, it effectively solves the problems of unscientific arrangement of battery units 4 in existing underwater pressure-bearing battery modules, resulting in wasted space in the underwater pressure-bearing compartment, and the cumbersome process of installing multiple battery modules sequentially. Specifically:

[0052] By setting up the battery support 1, the battery units 4 are arranged evenly, allowing more battery units 4 to be accommodated within the effective space; by setting up the fixing rod 3, multiple battery supports 1 busbars 2 are fixed on the fixing rod 3 and become a whole, realizing the modular assembly of the battery module; by setting up the connector 5, the installation path of external cables is constrained, reducing the use of cables and allowing more space in the underwater pressure tank to install battery units 4.

[0053] According to the battery module provided in the embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the connector 5 includes a Z-shaped connecting plate 501, and there are at least two Z-shaped connecting plates 501, which are disposed opposite to each other on the battery support 1.

[0054] In some embodiments, bolt holes are provided on the battery support 1, and the connector 5 is selected as a combination of bolts and nuts, or multiple connecting rods, etc., as long as it can connect the battery module and the underwater pressure battery compartment.

[0055] In this embodiment, the connector 5 is preferably a Z-shaped connecting plate 501, with at least two of them arranged opposite each other on the battery support 1. The battery module and the underwater pressure tank are connected by the Z-shaped connecting plate 501, so that the battery module is fixed in the pressure tank. The Z-shaped connecting plate 501 also constrains the installation path of the cable, thereby reducing the length of the external cable and requiring only a small amount of space to install the cable, so that the pressure tank has more space to install the battery unit 4.

[0056] The underwater pressure battery compartment provided according to the embodiments of this utility model, such as Figure 1 , Figures 6 to 8 As shown, the battery module described above also includes:

[0057] The cabin 6 has a battery mounting cavity 601 with one end open;

[0059] The battery module is installed in the battery mounting cavity 601, and the connector 5 is connected to the end cover 7.

[0060] In this embodiment, an underwater pressure battery compartment is provided. The compartment 6 has a battery mounting cavity 601 inside for mounting a battery module connected as a whole by a fixing rod 3, and an end cap 7 installed at the opening end 602 of the compartment 6. The end cap 7 has a first through hole 701, through which cables can be connected to the connector on the battery module, thereby using or charging the battery module in the compartment 6. At the same time, the connector 5 is connected to the end cap 7, which restricts the path of the cable to the connector on the battery module, reduces the use of cables, and reduces the proportion of space occupied by cables in the compartment 6, providing more space for the installation of the battery module in the compartment 6, and thus enabling the installation of more cables.

[0061] The underwater pressure battery compartment provided according to the embodiments of this utility model, such as Figure 9 As shown, the end cap 7 is also provided with a second through hole 702; a plug 8 is movably fitted into the second through hole 702, and part of the plug 8 extends to the outside of the second through hole 702;

[0062] There is a sealing structure between the plug 8 and the end cap 7.

[0063] In some embodiments, the sealing structure between the plug 8 and the end cap 7 can be selected as a sealing ring or direct welding, etc., so that the external environment cannot interfere with the battery module inside the pressure battery compartment.

[0064] In this embodiment, the end cap 7 is provided with a second through hole 702 and a plug 8 that is movably engaged with the second through hole 702. A sealing structure is provided between the plug 8 and the end cap 7, and part of the plug 8 is inside the end cap 7 and part of the plug 8 is on the surface of the end cap 7. By setting the plug 8, it is ensured that when the pressure battery compartment is working underwater, water pressure and other factors will not cause damage to the battery module.

[0065] The underwater pressure battery compartment provided according to the embodiments of this utility model, such as Figures 9 to 11 As shown, the plug 8 includes a disc body 801 and a rod body 802, with the rod body 802 coaxially connected to the disc body 801;

[0066] A first annular groove 8011 is coaxially formed on the end face of the disc body 801 near the rod body 802, and a first sealing ring 8012 is provided in the first annular groove 8011.

[0067] A second annular groove 8021 is provided on the outer surface of the rod 802 along the circumferential direction, and a second sealing ring 8022 is provided in the second annular groove 8021.

[0068] In this embodiment, the plug 8 includes a disc body 801 and a rod body 802. The disc body 801 has a first annular groove 8011 on its end face near the rod body 802. A first sealing ring 8012 is provided in the first annular groove 8011, and the first sealing ring 8012 is axially arranged to ensure that the disc body 801 and the end cover 7 fit tightly. The rod body 802 has a second annular groove 8021 on its circumference, and a second sealing ring 8022 is provided in the second annular groove 8021, and the second sealing ring 8022 is radially arranged. During use, the first sealing ring 8012 first provides a sealing effect. When the first sealing ring 8012 fails due to aging, external damage, etc., the second sealing ring 8022 inside the end cover 7 then provides a sealing effect, so that the sealing effect of the pressure chamber has double protection, reducing the risks encountered by the battery module.

[0069] The underwater pressure battery compartment provided according to the embodiments of this utility model, such as Figure 1 and Figure 8 As shown, the cabin 6 is cylindrical, and the battery mounting cavity 601 is cylindrical.

[0070] In some embodiments, the housing 6 is rectangular, square or other shapes, and the battery mounting cavity 601 is cubic or other shapes, as long as the battery mounting cavity 601 is inside the housing 6.

[0071] In this embodiment, the battery mounting cavity 601 is cylindrical and the compartment 6 is cylindrical, making the most of the space in the compartment 6 so that the compartment 6 can accommodate more battery units 4.

[0072] The underwater pressure battery compartment provided according to the embodiments of this utility model, such as Figure 9 and Figure 12 As shown, the end cap 7 is threadedly connected to the cabin 6, and multiple third sealing rings 9 are provided at the threaded connection.

[0073] In this embodiment, the end cap 7 is threadedly connected to the cabin 6, so that the end cap 7 and the cabin 6 fit tightly together and will not easily loosen. At the same time, multiple third sealing rings 9 are provided at the connection between the end cap 7 and the cabin 6 to ensure that the end cap 7 and the cabin 6 fit tightly together even more. During underwater use, the battery module inside the cabin 6 will not be damaged by external factors.
