[0001] This application belongs to the field of hybrid dump truck technology, specifically relating to an energy storage module and a hybrid dump truck. Background Technology

[0002] With the continuous expansion of the mining market, hybrid dump trucks have become mainstream transportation equipment. To meet the matching requirements of high-horsepower engines and large-capacity batteries, these vehicles typically require multiple sets of power batteries. However, although existing models generally integrate battery modules into the battery compartment, the supporting electrical control modules, thermal management systems, etc., are still distributed within the battery compartment. This results in low utilization of vehicle deck space and complex wiring, which not only limits the improvement of the vehicle's overall energy capacity but also causes inconvenience for subsequent maintenance. In addition, existing battery systems generally lack effective insulation design, resulting in low energy utilization and difficulty in adapting to the operating requirements of extremely cold conditions, thus limiting the vehicle's environmental adaptability. Summary of the Invention

[0019] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0021] Example On the one hand, please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides an energy storage module, and more particularly relates to an energy storage module for storing electrical energy, which is applied to a hybrid dump truck. The energy storage module is adaptable to the space on the deck of the hybrid dump truck.

[0022] In this embodiment, the energy storage module includes an integrated frame 100, a DC-DC converter 600, a thermal management unit 300, a high-voltage box module 400, and multiple battery modules 200. The DC-DC converter 600, thermal management unit 300, high-voltage box module 400, and multiple battery modules 200 are all integrated on the integrated frame 100, and the surface of the integrated frame 100 is encapsulated with a thermal insulation structure 700. The DC-DC converter 600, thermal management unit 300, and high-voltage box module 400 are used to coordinate and manage the input and output of electrical energy in the battery modules 200.

[0023] The integrated frame 100 has a three-layer structure, comprising a first-layer frame 110, a second-layer frame 120, and a third-layer frame 130 vertically from bottom to top. The first-layer frame 110 contains at least four battery compartments (at least two first battery compartments 110a and at least two second battery compartments 110b described below). The second-layer frame 120 contains a thermal management compartment 120c and at least two battery compartments (a third battery compartment 120a and a fourth battery compartment 120b described below). The third-layer frame 130 contains a high-voltage compartment 130a. Each battery compartment contains a battery module 200. A DC-DC converter 600 is located within the second-layer frame 120; a thermal management unit 300 is located on the second-layer frame 120 and housed within the thermal management compartment 120c; and a high-voltage module 400 is located on the third-layer frame 130 and housed within the high-voltage compartment 130a.

[0024] It is understood that the energy storage module provided in this embodiment integrates the DC converter 600, thermal management unit 300, high voltage box module 400 and multiple battery modules 200 into a whole energy management unit through the integrated frame 100. The integrated frame 100 adopts a bottom-up layout design, which can make reasonable use of horizontal and vertical space to better adapt to the space on the deck of the hybrid dump truck, maximize the utilization of the deck space, facilitate the subsequent wiring of the energy management system, and reduce the difficulty of inspection and maintenance.

[0025] Furthermore, the first layer of the integrated frame 100 has at least four battery compartments for mounting battery modules 200 on the first layer frame 110, and at least two battery compartments for mounting battery modules 200 on the second layer frame 120. In this way, at least six battery modules 200 can be installed, which greatly increases the battery capacity and thus effectively improves the energy storage capacity of the whole vehicle.

[0026] Please refer to the following: Figure 4In addition, the surface of the integrated frame 100 is encapsulated with a thermal insulation structure 700, which can provide overall thermal insulation for the DC converter 600, thermal management unit 300, high voltage box module 400 and multiple battery modules 200. Through the cooperation of the thermal insulation structure 700 and the thermal management unit 300, the stable operation of the energy system and the efficient output of energy are ensured under extremely cold conditions, so as to meet the operational requirements of extremely cold conditions.

[0027] To more clearly describe the technical solution of this application, the energy storage module provided in this embodiment is described in detail below: Please see Figure 1 and Figure 5 Each of the multiple battery modules 200 includes a mounting tray 210 and a battery body 220; the battery body 220 is detachably mounted on the mounting tray 210 by bolts, screws or rivets. Each battery compartment on the first frame 110 and the second frame 120 has a mounting position (e.g., a threaded mounting bracket) for mounting the tray 210 at its bottom.

[0028] Thus, when installing the battery module 200 in the battery compartment, the battery body 220 is first installed onto the corresponding mounting tray 210, and then the tray is installed into the corresponding mounting position in the battery compartment. The mounting tray 210 can be secured to the mounting position using bolts, screws, or rivets for easy installation and removal.

[0029] It is understandable that the battery bodies 220 in different battery modules 200 can be the same or different in size, meaning that the batteries vary in size. The mounting tray 210 is adapted to the size of the corresponding battery body 220; that is, small batteries have small trays, and large batteries have large trays. The mounting trays 210 used in the battery modules 200 are of the same type of construction, differing only in size. This makes installation and removal easier and improves overall maintainability.

[0030] In this embodiment, the mounting tray 210 adopts a frame structure, which saves materials and reduces weight while ensuring structural strength. Specifically, the mounting tray 210 includes a frame 211 with a hollow center. An "X"-shaped stabilizer 212 is arranged in the center of the frame 211. The four top ends of the stabilizer 212 extend to the four corners of the frame and are welded to the frame 211. The frame 211 has battery mounting seats at both ends along its length that mate with the battery compartment, and mounting holes for mounting the battery body 220 are provided on both sides along its width.

[0031] Please see Figure 1 , Figure 2 and Figure 3Furthermore, the first-layer frame 110 is provided with a first battery mounting area and a second battery mounting area along a first horizontal direction, and each of the first and second battery mounting areas is provided with at least two battery compartments. The battery compartments in the first and second battery mounting areas are arranged along a second horizontal direction, wherein, along the first horizontal direction, the length of the battery compartment in the first battery mounting area is greater than the length of the battery compartment in the second battery mounting area.

[0032] In this embodiment, the first horizontal direction intersects with the second horizontal direction, or alternatively, the first horizontal direction and the second horizontal direction are perpendicular to each other. Therefore, this embodiment establishes a three-dimensional coordinate system, with the X-axis representing the first horizontal direction, the Y-axis representing the second horizontal direction, and the Z-axis representing the vertical direction.

[0033] For ease of description, the battery compartment located in the first battery mounting area is defined as the first battery compartment 110a, and there are two first battery compartments 110a; the battery compartment located in the second battery mounting area is defined as the second battery compartment 110b, and there are two second battery compartments 110b. Along the first horizontal direction, the length of the first battery compartment 110a is greater than the length of the second battery compartment 110b. Thus, the first battery compartment 110a is used to install a large-capacity battery module 200, while the second battery compartment 110b can be used to install a relatively small-capacity battery module 200.

[0034] Furthermore, the openings of the first battery compartment 110a and the second battery compartment 110b face opposite directions and are parallel to the first horizontal direction, respectively. This allows for both adaptation to the space on the deck of the hybrid dump truck and convenient installation, removal, and maintenance of the battery modules 200 from the corresponding openings.

[0035] The two battery compartments within the second-layer frame 120 are a third battery compartment 120a and a fourth battery compartment 120b, which are arranged on adjacent sides of the thermal management compartment 120c. Furthermore, along the first horizontal direction, the length of the third battery compartment 120a is greater than the length of the fourth battery compartment 120b. Thus, the third battery compartment 120a is used to install a large-capacity battery module 200, while the fourth battery compartment 120b can be used to install a relatively smaller-capacity battery module 200.

[0036] It should be noted that the battery body 220 is usually an outsourced component, and the customization cost is relatively high. To save costs, a fixed-size model produced by the manufacturer can be directly selected. Therefore, in this embodiment, a battery compartment combination structure of one large and one small is set on the first layer frame 110 and the second layer frame 120 to accommodate the combined use of the purchased battery body 220, saving manufacturing costs while maximizing battery capacity and output power, thereby effectively improving the energy storage capacity of the entire vehicle. Of course, in some embodiments, without considering cost, battery bodies 220 of the same size can be customized, so that battery compartments of the same size can be designed on the first layer frame 110 and the second layer frame 120.

[0037] Furthermore, the openings of the third battery compartment 120a and the fourth battery compartment 120b face opposite directions and are parallel to the first horizontal direction, respectively. This allows for both adaptation to the space on the deck of the hybrid dump truck and convenient installation, removal, and maintenance of the battery modules 200 from the corresponding openings.

[0038] In this embodiment, the opening of the thermal management compartment 120c is located on the side away from the fourth battery compartment 120b, and the opening of the thermal management compartment 120c faces a direction parallel to the second horizontal direction. Specifically, the side of the thermal management compartment 120c away from the fourth battery compartment 120b is a wide side, so setting the opening on this side allows for a larger design space, thus facilitating the connection of the wiring or piping of the thermal management unit 300.

[0039] In terms of vertical projection, the projected area of ​​the third-layer frame 130 is smaller than that of the second-layer frame 120, and the projected area of ​​the second-layer frame 120 is smaller than that of the first-layer frame 110. This layout makes better use of the vertical space of the hybrid dump truck's deck, resulting in a more rational spatial arrangement.

[0040] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the first-layer frame 110 includes a lower frame 111, a first-layer upper frame 112, a plurality of main support columns 113, and a plurality of first secondary columns 114. The lower frame 111 has a plurality of right-angle corners, and the plurality of main support columns 113 are all disposed on the lower frame 111 and respectively arranged at the corner positions of the lower frame 111. Thus, the main support columns 113 are constructed as the side edges of the first-layer frame 110.

[0041] The first upper frame 112 is positioned above the lower frame 111 and mounted on the main support column 113. Multiple first secondary columns 114 support and connect the lower frame 111 and the first upper frame 112. Thus, the space between the first upper frame 112 and the lower frame 111 is divided by the first secondary support columns 113 into two first battery compartments 110a and two second battery compartments 110b. The first secondary columns 114 enhance the structural strength between the first upper frame 112 and the lower frame 111, and also effectively protect the battery modules.

[0042] In this embodiment, both the lower frame 111 and the first-layer upper frame 112 include a middle beam 1112, multiple horizontal beams 1110 spaced apart along a first horizontal direction, and two longitudinal beams 1111 spaced apart along a second horizontal direction. The two longitudinal beams 1111 are arranged at both ends of the horizontal beams 1110 and welded to the horizontal beams 1110. A middle beam 1112 spaced along the first horizontal direction is welded between two adjacent horizontal beams 1110. Battery mounting positions corresponding to the first battery compartment 110a and the second battery compartment 110b are formed between the middle beam 1112 and the longitudinal beams 1111 in the lower frame 111; battery mounting positions corresponding to the third battery compartment 120a or the fourth battery compartment 120b are formed between the middle beam 1112 and the longitudinal beams 1111 in the first-layer upper frame 112. The battery mounting position is provided with a reinforcing beam structure 115, which is arranged along the second horizontal direction and welded to the intermediate beam 1112 and the longitudinal beam 1111 at the corresponding ends.

[0043] The reinforcing beam structure 115 includes inclined tubes 1150 and horizontal tubes 1151. The horizontal tubes 1151 are arranged along a second horizontal direction, and their two ends are welded to corresponding intermediate beams 1112 and longitudinal beams 1111, respectively. An inclined tube 1150 is provided on each side of the horizontal tube 1151 in a first horizontal direction. One end of the inclined tube 1150 is welded to the body of the horizontal tube 1151, and the other end is welded to the corresponding intermediate beam 1112 or longitudinal beam 1111. In this way, the horizontal tubes 1151 and inclined tubes 1150 structurally reinforce the battery mounting position of the battery compartment, enabling the battery mounting position to withstand the weight of the battery module 200 and improving the stability of the entire integrated frame 100.

[0044] Please see Figure 1 , Figure 2 and Figure 3The second-layer frame 120 and the first-layer frame 110 can share some main support columns 113. Specifically, the second-layer frame 120 includes a second-layer upper frame 121 and multiple second-layer auxiliary columns 122. The second-layer upper frame 121 is arranged above the first-layer upper frame 112 and welded to the top of the main support columns 113; the multiple second-layer auxiliary columns 122 support and connect between the first-layer upper frame 112 and the second-layer upper frame 121. Thus, the space formed between the second-layer upper frame 121 and the first-layer upper frame 112 can be divided by the second-layer auxiliary columns 122 into a third battery compartment 120a, a fourth battery compartment 120b, and a thermal management compartment 120c. The third battery compartment 120a can be located directly above the first battery compartment 110a, and the fourth battery compartment 120b can be located directly above the second battery compartment 110b.

[0045] Furthermore, such as Figure 2 and Figure 3 As shown, the second-layer frame 120 also includes a sub-frame 123, which is disposed on top of the first-layer upper frame 112 and connected to the second sub-column 122. A DC converter compartment 120d for mounting the DC converter 600 is formed between the sub-frame 123 and the first-layer upper frame 112. The distance from the top of the sub-frame 123 to the first-layer upper frame 112 is less than the distance from the top of the second-layer upper frame 121 to the first-layer upper frame 112.

[0046] Please see Figure 1 , Figure 2 and Figure 3 The third-layer frame 130 includes a third-layer upper frame 131 and multiple third-layer auxiliary columns 132. The third-layer upper frame 131 is arranged above the second-layer upper frame 121; the multiple third-layer auxiliary columns 132 support and connect the second-layer upper frame 121 and the third-layer upper frame 131, and are arranged around the periphery between the third-layer upper frame 131 and the second-layer upper frame 121. Thus, the space formed between the third-layer upper frame 131 and the second-layer upper frame 121 is the high-voltage compartment 130a. In this embodiment, the high-voltage compartment 130a is located above the third battery compartment 120a.

[0047] Understandably, in this embodiment, the entire integrated frame 100 is constructed using frame welding, ensuring structural strength and providing comprehensive protection for the DC-DC converter 600, thermal management unit 300, high-voltage box module 400, and multiple battery modules 200. Furthermore, the integrated frame 100 employs a three-layer structure to adapt to the space on the deck, resulting in a rational structural design and a more compact layout. This integration method also saves on wiring distances, simplifies wiring, and facilitates subsequent inspection and maintenance of the entire energy management unit.

[0048] Please see Figure 4and Figure 6 The insulation structure 700 covers the entire outer surface of the integrated frame 100. The insulation structure 700 includes multiple end plates 710 and multiple insulation layers 720. The end plates 710 are mounted to the integrated frame 100 using fasteners 730 (e.g., screws, bolts, or rivets). The insulation layers 720 are located on the side of the end plates 710 facing the integrated frame 100.

[0049] Thus, the integrated frame 100 adopts a segmented sealing plate 710 and insulation layer 720 on the outside. The sealing plates 710 are optimized and adjusted according to the location of the electrical modules to be installed and the maintenance requirements, making each sealing plate 710 easy to install and remove, self-consistent in terms of hierarchy, and improving the insulation effect. Furthermore, through the cooperation of the insulation structure 700 and the thermal management unit 300, the stable operation of the energy system and the efficient output of energy are ensured under extremely cold conditions.

[0050] Optionally, the insulation layer 720 is bonded to the sealing plate 710, wherein the insulation layer 720 can be made of materials such as insulation cotton, vacuum insulation board, polyimide foam or aerogel.

[0051] Please see Figure 2 and Figure 3 In this embodiment, the energy storage module also includes an expansion tank 500, which is arranged on the top of the integrated frame 100 and connected to the third-layer frame 130 via a tank mounting base 140. The expansion tank 500 is connected to the thermal management unit 300 and is located on the outward side of the high-pressure chamber 130a in the second horizontal direction, which facilitates the addition of coolant and allows for easy observation of the coolant level from the side of the dump truck.

[0052] On the other hand, please see Figures 1 to 6 This embodiment also provides a hybrid dump truck. The hybrid dump truck includes the energy storage module provided above. Thus, the hybrid dump truck has all the beneficial effects brought by the energy storage module described above, which will not be repeated here as they have already been described in detail.
