[0028] Please refer to Figures 1 to 2 The embodiment of the present invention provides an electrical module frame, including a longitudinal beam 1, a transverse beam 2 and a frame unit. Among them, the longitudinal beam 1 is provided with multiple longitudinal beams 1 and the multiple longitudinal beams 1 are arranged in parallel. The connection lines between the multiple longitudinal beams 1 constitute a rectangular frame area. The frame units are sequentially arranged in multiple layers between the frame areas along the up and down directions. Each layer of frame units has an independent layout function, which can effectively separate and organize different types of electrical modules to avoid spatial conflicts. At the top of the frame area, multiple vertical beams are connected together by the transverse beam 2 to form the basic skeleton of the electrical module frame to improve stability. Among them, a first mounting plate 5 is detachably mounted on at least two frame units. In this embodiment, the first mounting plate 5 is set on the outermost frame unit and another frame unit adjacent to the outermost frame unit. The battery or electrical module is mounted on the frame unit through the first mounting plate 5, which is convenient for installation and disassembly and simplifies the installation and replacement process of the electrical module.

[0029] Preferably, the frame unit includes a load-bearing tube 11 and a reinforcement tube 12. The load-bearing tube 11 is connected between multiple longitudinal beams 1. The axes of the multiple load-bearing tubes 11 are all located in the same plane, and multiple load-bearing areas for bearing the weight of the electrical module are formed on the longitudinal beam 1. The reinforcement tube 12 is connected between the load-bearing tube 11 and the longitudinal beam 1 to reinforce the overall structure of the electrical module frame, reduce the risk of structural deformation due to external stress, and improve safety.

[0030] To further enhance the strength of the electrical module frame and the stability of the installation, such as Figure 2 As shown, in this embodiment, support tubes 13 are provided between the load-bearing tubes 11 of adjacent frame units. When the electrical module frame carries a large number of batteries and battery modules, the support tubes 13 can provide additional support therefor, thereby reducing deformation under heavy loads and improving the structural stability of the overall frame.

[0031] An embodiment of the present invention also provides a power supply device, including a rechargeable battery 3, an energy storage battery 4 and the above-mentioned electrical module frame, wherein the rechargeable battery 3 and the energy storage battery 4 are installed on the outermost frame unit among multiple frame units and another frame unit adjacent to the outermost frame unit.

[0032] In this embodiment, the frame unit is provided with three layers, two rechargeable batteries 3 and four energy storage batteries 4 are installed on the lower layer of the frame unit, the batteries are directly connected to the load-bearing tube 11 of the lower layer of the frame unit by bolts and nuts, and the wiring ports of the two rechargeable batteries 3 are installed in advance to the front end of the lower layer of the frame unit, and the wiring ports of the four energy storage batteries 4 are installed at the terminal and rear end of the lower layer of the frame unit. Four rechargeable batteries 3 and two energy storage batteries 4 are installed on the middle layer of the frame unit, and these batteries are installed on the middle layer of the frame unit through the first mounting plate 5, among them, two energy storage batteries 4 are installed at the middle end of the middle layer of the frame unit, and four rechargeable batteries 3 are installed at the front end and rear end of the middle layer of the frame unit. In electric and hybrid vehicles, the position of the vehicle's center of gravity directly affects the driving stability, and the weight of the energy storage battery 4 is larger than that of the rechargeable battery 3, so in this embodiment, the four energy storage batteries 4 are placed in the lower layer of the frame unit, so that the center of gravity of the vehicle is lower, and the two energy storage batteries 4 are placed at the middle end of the middle layer of the frame unit, so that the overall center of gravity is closer to the center of the vehicle, thereby reducing the possibility of rollover or tilting of the vehicle during driving.

[0033] In this embodiment, the power supply device further comprises three thermal management modules 10, three heating modules 9, three expansion water tanks 7 and one high-voltage box 8. The thermal management module 10, the heating module 9 and the high-voltage box 8 are all installed on the first mounting plate 5 of the upper layer of the frame unit, so that each module can be more easily accessed and operated when maintenance, inspection or replacement is required, without interfering with the batteries in the lower and middle layers of the frame unit.

[0034] As shown in Figure 3 Two thermal management modules 10 and two heating modules 9 are installed at the right front end of the upper layer of the frame unit. The thermal management module 10 and the heating module 9 serve as the main heat source and are arranged at the right front end of the upper layer of the frame unit, which can effectively concentrate heat above the power supply device, facilitating natural heat dissipation and air circulation. The high-voltage box 8 is installed at the rear end of the upper layer of the frame unit, and the other thermal management module 10 is installed at the left front end of the upper layer of the frame unit, and the other heating module 9 is installed at the right rear side of the upper layer of the frame unit, which is dispersed from the above-mentioned main heat source, which is beneficial to balance the heat distribution on both sides, avoid the heat concentration area too single, improve the overall heat dissipation efficiency.

[0035] As shown in Figure 4As shown, in this embodiment, the power supply device further includes a second mounting plate 6 disposed at the topmost portion of the electrical module frame and a sealing plate 14 arranged circumferentially along the electrical module frame. Three expansion water tanks 7 are mounted on the second mounting plate 6. Specifically, the two longitudinal beams 1 at the ends of the electrical module frame extend upward beyond the electrical module frame, and the second mounting plate 6 is mounted between these two extended longitudinal beams 1. This positions the three expansion water tanks 7 outside the electrical module frame, free from obstruction by the sealing plate 14. This makes coolant refilling more convenient, and the liquid level can be directly checked from the side, enhancing convenience.

[0036] In this embodiment, the sealing plate 14 is a segmented sealing plate 14, and the sealing plate 14 can be specially adjusted according to the position of the electrical module to be assembled. When a specific module needs to be inspected or maintained, it is only necessary to disassemble the corresponding sealing plate 14 segment without completely removing the entire sealing plate 14, thereby reducing maintenance time and workload.

[0037] An embodiment of the present invention further provides a dump truck, comprising a deck 15 and the above-mentioned power supply device, wherein the power supply device is installed on the deck 15 .

[0038] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.
