Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this utility model is to provide an integrated mounting bracket for an energy storage system to solve the problems existing in the prior art. It can not only achieve stable installation of battery packs, but also quickly combine and match battery packs according to the vehicle's range requirements to achieve a neat layout of multiple battery packs without requiring large-scale modifications to the vehicle chassis frame, thus making it more versatile.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-3 As shown, this embodiment provides an integrated mounting bracket for an energy storage system, including a bracket body and a connecting part fixed to the top of the bracket body. The connecting part is used to connect to the chassis frame of a vehicle. The vehicle targeted in this embodiment can be a commercial vehicle or other vehicles. The bracket body is a frame structure with multiple battery pack mounting parts arranged neatly. Each battery pack mounting part includes a first crossbeam 1 and a first longitudinal beam 2. At least two first crossbeams 1 are arranged in parallel. The two ends of the first longitudinal beam 2 are fixedly connected to two adjacent first crossbeams 1, respectively. Specifically, the first crossbeams 1 and the first longitudinal beams 2 are perpendicular to each other. The dimensions of the first crossbeams 1 and 2 can be adapted to the size of the connected battery pack 12. The first crossbeams 1 and / or the first longitudinal beams 2 are used to connect to the bottom of the battery pack 12, which can be done by bolt connection or other connection methods.

[0023] In use, the battery pack 12 is placed on the battery pack mounting part, and the first crossbeam 1 and the first longitudinal beam 2 support the battery pack 12. The battery pack 12 usually has a shell, which is fixedly connected to the first crossbeam 1 and / or the first longitudinal beam 2.

[0024] Therefore, this embodiment uses an integrated mounting bracket for the energy storage system to fix the battery pack 12, achieving stable installation and allowing for quick combination and arrangement of multiple battery packs according to the vehicle's range requirements. This eliminates the need for large-scale modifications to the vehicle chassis, enhancing applicability and significantly improving the adaptability and market competitiveness of commercial vehicles. Furthermore, the battery pack mounting section in this embodiment relies on the first crossbeam 1 and the first longitudinal beam 2 for support and fixation, resulting in a simple structure, low cost, and ease of manufacturing, thus facilitating widespread adoption.

[0025] To facilitate the fixing of the battery pack 12, in this embodiment, the upper surface of the first longitudinal beam 2 is flush with the upper surface of the first cross beam 1, so that the bottom of the battery pack 12 can fit against the first cross beam 1 and the first longitudinal beam 2. The first longitudinal beam 2 has a first through hole for passing through the bolts connecting the battery pack 12, and the battery pack 12 is detachably fixed by the bolts.

[0026] In this embodiment, the connecting part includes a vertical plate 7, on which multiple strip-shaped holes 8 are spaced apart from top to bottom. The strip-shaped holes 8 are arranged horizontally and are used for bolts connecting to the chassis frame to pass through. At the same time, the chassis frame has a connecting structure that connects to the vertical plate 7. By setting the vertical plate 7 and the strip-shaped holes 8, the main body of the bracket can be quickly and accurately installed on the chassis frame, greatly shortening the installation time and improving the assembly efficiency.

[0027] To ensure the stability of the vertical plate 7 structure, in this embodiment, a reinforcing rib 10 is also connected between the vertical plate 7 and the main body of the support.

[0028] During processing, steel plates can be bent into L-shaped plates. The short side of the L-shaped plate is fixedly connected to the main body of the support, and the long side of the L-shaped plate serves as the vertical plate 7, connecting to the chassis frame. The rib plate 10 has a right-angled triangular structure; its long side is welded to the long side of the L-shaped plate, and its short side is welded to the short side of the L-shaped plate, thereby increasing the strength of the vertical plate 7. Figure 3 As shown.

[0029] In this embodiment, the main body of the support structure includes a top layer structure and a bottom layer structure, such as Figure 2 As shown, the top and bottom structures are connected by columns 9, and both structures have multiple battery pack mounting parts. Specifically, in this embodiment, the top structure has a heat dissipation system 13 mounting part, which includes a second crossbeam 3 and a second longitudinal beam 4. The second longitudinal beam 4 has a second through hole for bolts connecting the heat dissipation system 13 to pass through. The liquid cooling pipes in the heat dissipation system 13 are connected in series with each battery pack 12 through the radiator connection outlet to form a complete circulation loop, thereby cooling the battery pack 12 and ensuring that the battery pack 12 can operate stably for a long time.

[0030] The top-level structure of this embodiment also includes a battery management system 14 mounting section, which comprises a third crossbeam 5 and a third longitudinal beam 6. The third longitudinal beam 6 has a third through hole for threading bolts that connect to the battery management system 14. The battery management system 14 is used to monitor the battery's status, such as current charge level and operating temperature.

[0031] The heat dissipation system 13 and the battery management system 14 are both commonly used devices in the art, and their structure and working principle will not be described in detail in this embodiment. The heat dissipation system 13 and the battery management system 14 are installed in the top layer structure for ease of disassembly and assembly.

[0032] This embodiment, by incorporating a heat dissipation system 13 and a battery management system 14 on the support body, enables real-time and precise monitoring and control of the battery status, achieving comprehensive protection and management of the battery pack 12. Furthermore, by integrating the battery pack 12, heat dissipation system 13, and battery management system 14 all within the support body, a neat layout of the energy storage system components is achieved, reducing the need for dispersed installation of these components on the chassis. Simultaneously, the neat layout facilitates assembly and debugging during the production process.

[0033] In the top-level structure of this embodiment, the heat dissipation system 13 mounting section and the battery management system 14 mounting section are located on both sides of the battery pack mounting section, placing the heavier battery pack in the middle position to ensure the stability of the overall system. The heat dissipation system 13 mounting section, battery pack mounting section, and battery management system 14 mounting section in the top-level structure correspond one-to-one with the multiple battery pack mounting sections in the bottom-level structure. To ensure the structural specifications of the bracket body and facilitate processing, in this embodiment, the centerlines of the first crossbeam 1, the second crossbeam 3, and the third crossbeam 5 are located on the same vertical plane along their length. The volume of the battery pack 12 is typically larger than that of the heat dissipation system 13 and the battery management system 14. To meet the installation requirements of the battery pack 12 in the top-level structure, the height of the first crossbeam 1 in the top-level structure can be slightly lower than the heights of the second crossbeam 3 and the third crossbeam 5.

[0034] The column 9 is connected to the first crossbeam 1, the second crossbeam 3, and the third crossbeam 5, and the connecting part is connected to the top of the column 9.

[0035] The underlying structure may consist of only multiple battery pack mounting sections, with the first crossbeams 1 of these mounting sections interconnected. During fabrication, a longer beam can be used to connect the columns 9, and diagonal braces 11 can be installed between the columns 9 and this longer beam to enhance support strength. Functionally, this longer beam can be divided into multiple first crossbeams 1 connected end to end.

[0036] In this embodiment, the first crossbeam 1, the second crossbeam 3, the third crossbeam 5, the first longitudinal beam 2, the second longitudinal beam 4, the third longitudinal beam 6, and the column 9 can all be made of Q345 steel and connected to each other by welding. The integrated welded bracket body in this embodiment has extremely high structural strength and stability, and can effectively resist various vibrations and impacts during vehicle operation, providing a reliable installation foundation for energy storage system components.

[0037] In this embodiment, the first crossbeam 1, the second crossbeam 3, the third crossbeam 5, and the column 9 are all square steel, while the first longitudinal beam 2, the second longitudinal beam 4, and the third longitudinal beam 6 can be channel steel with the flat surface of the channel steel facing upwards to provide good support.

[0038] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0039] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
