[0037] This embodiment provides a battery box base structure to provide support and mobility for easy disassembly and maintenance.

[0038] Please refer to Figs. 1 to 3 Specifically, the battery box base structure includes a base box 10 and multiple rolling support structures 20. The base box 10 is used to support the battery pack. The multiple rolling support structures 20 are evenly distributed at the bottom of the base box 10 and are rotatably connected to the base box 10. The rolling support structures 20 are used to support the base box 10 and make the base box 10 movable.

[0039] In this embodiment, the battery box base structure utilizes multiple rolling support structures 20 at the bottom of the base box 10 to provide support for the base box 10, ensuring stability whether in a moving or fixed state. Simultaneously, the rolling support structures 20 are rotatably connected to the base box 10, allowing the battery box with the base structure to be moved during installation or maintenance. This facilitates the disassembly and maintenance of the battery box, solving the problem of traditional bases requiring additional equipment for movement, reducing operational complexity and time costs. Furthermore, the even distribution of the rolling support structures 20 improves the stability of the support for the battery box, preventing swaying or tipping during movement. Moreover, all rolling support structures 20 are identical and of uniform specifications, making maintenance relatively convenient.

[0040] Optionally, the base tray housing 10 includes a base plate and side beams 11. The side beams 11 are disposed on the base plate and enclose a receiving cavity for accommodating the battery pack. Optionally, the base tray housing 10 can be manufactured by extruding and welding aluminum profiles, or by stamping and welding sheet metal, etc., without specific limitations. Exemplarily, the base tray housing 10 is manufactured by extruding and welding aluminum profiles, which has a high degree of lightweighting and high structural strength, and can also integrate a thermal management device 12 to achieve thermal management of the battery.

[0041] Specifically, a thermal management device 12 is integrated inside the base box 10. A heat exchange fluid flows inside the thermal management device 12. The thermal management device 12 is used to perform thermal management on the battery pack loaded in the base box 10, so as to achieve thermal management of the battery.

[0042] Optionally, the thermal management device 12 can be a cold plate structure, and the cooling cavity of the cold plate can be directly adopted as the cavity structure inside the aluminum profile box of the bottom support box 10.

[0043] More specifically, the thermal management device 12 also includes two connecting water pipes that are connected to the cooling chamber as inlet and outlet water pipes, thereby enabling the flow of heat exchange fluid in the cooling chamber to achieve better heat dissipation for the battery.

[0044] Furthermore, the base box 10 also includes a fixing beam 13, which is connected inside the base box 10 and is used to support and install the battery pack.

[0045] Optionally, the base box 10 is also provided with fixing holes for connecting with the cover of the battery box, so that the battery box can form a sealed chamber for battery pack installation.

[0046] Please continue to refer to Figs. 1 to 3In this embodiment, the base box 10 includes two symmetrically arranged side beams 11, and multiple rolling support structures 20 are evenly distributed on the two side beams 11. This arrangement ensures that the rolling support structures 20 are installed only on the side beams 11 used for fixing, without damaging other structures of the base box 10, and without affecting the installation and use of the thermal management device 12.

[0047] Optionally, the specific number of rolling support structures 20 can be adapted to actual needs and is not specifically limited here.

[0048] For example, in this embodiment, each side beam 11 is provided with three rolling support structures 20 at intervals, which can realize the support of the battery box bottom support structure.

[0049] Specifically, the bottom of the side beam 11 is provided with a mounting hole 111. A part of the rolling support structure 20 is disposed inside the side beam 11, and the other part passes through the mounting hole 111 and extends out of the side beam 11, so that only a part of the rolling support structure 20 extends out of the side beam 11. This ensures that even if the rolling support structure 20 is added, the overall size of the battery box base structure will not increase too much. This arrangement also limits the rolling support structure 20, preventing it from shaking or tipping over, and improving the stability of the battery box base structure.

[0050] Furthermore, the battery box base structure also includes multiple fasteners 30, each corresponding to a multiple rolling support structure 20. The rolling support structure 20 is fitted onto the fastener 30, and the fastener 30 can be fixed to the side beam 11, allowing the rolling support structure 20 to be rotatably connected to the base box 10. Specifically, the side beam 11 is provided with a nut, and the fastener 30 is sequentially passed through one side of the side beam 11, the roller, and the other side of the side beam 11, and threadedly connected to the nut, thus enabling the installation of the rolling support structure 20.

[0051] Optionally, the rolling support structure 20 can be a rotating component such as a roller, which can support and rotate the battery box base structure. No specific limitation is made here.

[0052] Specifically, the battery box base structure also includes multiple connectors 40, which are disposed on the side beam 11 and are used to connect with the external battery compartment. The connectors 40 are used to fix the battery box base structure and the battery box.

[0053] More specifically, the connector 40 includes a lifting hole 41 and a threaded hole 42. The lifting hole 41 is used for positioning and lifting the battery, and the threaded hole 42 is used for fixed connection with the external battery compartment, thereby realizing the fixing and lifting of the battery box with the battery box base structure.

[0054] This embodiment also provides a battery box, characterized by including the battery box base structure described in any of the above-described solutions. By using this battery box base structure, the battery box can be made movable, thereby improving the portability for disassembly, assembly, and maintenance.

[0055] This embodiment also provides an energy storage device, which includes the battery box described in any of the above-described solutions. Using this battery box makes the assembly and maintenance of the energy storage device more convenient.
