[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] The following is for reference. Figures 1-3 This invention describes a battery module assembly 100, a battery device, and a vehicle according to embodiments of the present invention.

[0032] like Figures 1-3 As shown, according to an embodiment of the present invention, a battery module assembly 100 of a battery device includes a housing, and the battery module assembly 100 is installed in the housing. The battery module assembly 100 includes: a mounting base 10 for fixing to the housing; and a plurality of module units 20 located on the same side of the mounting base 10 along a first direction. Each module unit 20 includes a heat exchanger 21 and a battery module 22. The battery module 22 is fixed to the corresponding heat exchanger 21. The heat exchanger 21 and the mounting base 10 are detachably connected, and the heat exchanger 21 is detachably fixed to the housing.

[0033] Among them, such as Figure 1 As shown, the first direction is Figure 1 The Z-direction, the second direction is Figure 1 In the X direction, the third direction is Figure 1The Y-axis, first direction, second direction, and third direction are perpendicular to each other. The battery device includes a housing, in which the battery module assembly 100 is installed, making the overall structure of the battery device more compact and making effective use of space. Furthermore, the housing can resist the intrusion of external factors such as dust and moisture, thereby protecting the internal battery module assembly 100 from damage and improving the service life and reliability of the battery device.

[0034] The battery module assembly 100 includes a mounting base 10, which provides a stable support for the battery module assembly 100, ensuring that the battery module assembly 100 will not shift or shake due to vibration or impact during vehicle operation within the housing, thus helping to prevent damage to the internal components of the battery module assembly 100 and extending the service life of the battery module assembly 100.

[0035] Mounting base 10 is used to fix to the box body. In some embodiments of this application, mounting base 10 and box body can be fixedly connected by bolts, or mounting base 10 and box body can be fixedly connected by welding. However, this utility model is not limited to this. Mounting base 10 and box body can also be fixedly connected by other means, as long as mounting base 10 is used to fix to the box body.

[0036] The battery module assembly 100 includes a plurality of module units 20. In some embodiments of this application, the battery module assembly 100 may include two, three, four or other numbers of module units 20. However, this utility model is not limited to this. The battery module assembly 100 may also include other numbers of module units 20, as long as the battery module assembly 100 includes a plurality of module units 20.

[0037] Along the first direction, multiple module units 20 are located on the same side of the mounting base 10, making the connection and wiring between multiple module units 20 simpler and clearer. This helps to reduce the assembly difficulty of the battery module assembly 100 and improve production efficiency, and also facilitates subsequent maintenance and management of the battery device. The module units 20 arranged in the same direction can also more easily achieve a unified design of heat dissipation channels, which helps to reduce the operating temperature of the battery module assembly 100 and extend the service life of the battery device.

[0038] Each module unit 20 includes a heat exchanger 21 and a battery module 22, forming a highly modular structure. This makes the maintenance or replacement of a single module unit 20 simple and quick, without requiring large-scale disassembly of the entire battery module assembly 100. The battery module 22 is fixed to the corresponding heat exchanger 21. In some embodiments of this application, the battery module 22 and the heat exchanger 21 can be fixedly connected by adhesive or bolts. However, this utility model is not limited to these methods, and the battery module 22 and the heat exchanger 21 can also be fixedly connected by other means, as long as the battery module 22 is fixed to the corresponding heat exchanger 21. The heat exchanger 21, as a medium for heat transfer, can quickly dissipate the heat generated by the battery module 22. By cooperating with an external cooling system (such as a liquid cooling system), the temperature of the battery module 22 can be effectively controlled, improving heat dissipation efficiency.

[0039] The heat exchanger 21 and the mounting base 10 are detachably connected, allowing for easy disassembly and reinstallation of the module unit 20 when maintenance or replacement is required. This simplifies the maintenance process, reduces maintenance costs and time, and allows the remaining undamaged module units 20 to continue to be used, thereby improving the reusability of the module units 20. Furthermore, the heat exchanger 21 is detachably fixed to the housing, allowing for flexible adjustment of the number and layout of the module units 20 according to actual needs.

[0040] According to the battery module assembly 100 of the battery device in this embodiment of the present invention, each module unit 20 includes a heat exchanger 21 and a battery module 22. The battery module 22 is fixed to the corresponding heat exchanger 21, and the heat exchanger 21 is detachably connected to the mounting base 10. The heat exchanger 21 is also detachably fixed to the housing. This allows each module unit 20 to be repaired and replaced individually, eliminating the need to repair and replace the entire battery module assembly 100 when a single module unit 20 fails. This significantly reduces the maintenance cost of the battery module 22. Furthermore, when a single module unit 20 fails, the remaining unfailed module units 20 can still be used, improving the reusability of the module units 20.

[0041] According to some embodiments of the present invention, the battery module 22 is detachably disposed on the corresponding heat exchange component 21. In some embodiments of the present application, the battery module 22 and the corresponding heat exchange component 21 can be detachably connected by bolts, snap-fits, etc., so that when the battery module 22 malfunctions or needs maintenance, it can be easily removed from the heat exchange component 21, simplifying the maintenance process of the battery module 22 and reducing the maintenance difficulty of the battery module 22.

[0042] According to some embodiments of the present invention, such as Figure 2As shown, the corresponding heat exchanger 21 and battery module 22 are arranged along the first direction, and the heat exchanger 21 is located between the mounting base 10 and the corresponding battery module 22.

[0043] The heat exchanger 21 and the battery module 22 are arranged closely in the same direction, reducing space waste and making the battery device more compact and lightweight, thus improving space utilization. The heat exchanger 21 is located between the battery module 22 and the mounting base 10, which can directly and effectively dissipate the heat generated by the battery module 22, ensuring a short heat transfer path and improving heat dissipation efficiency.

[0044] According to some embodiments of the present invention, such as Figure 2 As shown, the heat exchanger 21 includes a heat exchange plate 211 and a first mounting beam 212. The heat exchange plate 211 is located between the mounting base 10 and the corresponding battery module 22. The heat exchange plate 211 and the mounting base 10 are detachably connected. The first mounting beam 212 is located on the side of the heat exchange plate 211 away from the mounting base 10 and is fixed to the heat exchange plate 211. The battery module 22 is fixed to the corresponding first mounting beam 212.

[0045] The heat exchange plate 211 is located between the mounting base 10 and the corresponding battery module 22, and can quickly and effectively absorb and dissipate the heat generated by the battery module 22, ensuring a short heat transfer path and thus improving heat dissipation efficiency. The heat exchange plate 211 and the mounting base 10 are detachably connected. In some embodiments of this application, the heat exchange plate 211 and the mounting base 10 can be detachably connected by bolts, snap-fits, etc., allowing a single module unit 20 to be easily removed from the mounting base 10 for maintenance or replacement. This effectively avoids the need to maintain or replace the entire battery module assembly 100 when a single module unit 20 fails, greatly reducing the maintenance difficulty of the battery device. Furthermore, when a single module unit 20 fails and cannot be used, its disassembly and replacement will not affect the remaining module units 20, allowing the remaining intact module units 20 to continue to be used, thus improving the reusability of the module units 20.

[0046] The first mounting beam 212 is located on the side of the heat exchange plate 211 away from the mounting base 10 and is fixed to the heat exchange plate 211. In some embodiments of this application, the first mounting beam 212 and the heat exchange plate 211 can be fixedly connected by bolts, or the first mounting beam 212 and the heat exchange plate 211 can be fixedly connected by welding. However, this utility model is not limited to this. The first mounting beam 212 and the heat exchange plate 211 can also be fixedly connected by other means, as long as the first mounting beam 212 is located on the side of the heat exchange plate 211 away from the mounting base 10 and is fixed to the heat exchange plate 211.

[0047] As an example of this application, the first mounting beam 212, the heat exchange plate 211, and the battery module 22 can be fixedly connected by bolts. The heat exchange plate 211 and the battery module 22 can also be bonded together by thermally conductive structural adhesive. This arrangement allows the battery module 22 to be more securely fixed to the heat exchange plate 211, thereby improving the stability and heat dissipation of the battery module 22. The heat exchange plate 211 can be made of a metal plate with high thermal conductivity (such as copper or aluminum), with holes or milled grooves inside to form flow channels, allowing coolant to circulate inside the heat exchange plate 211. The surface of the heat exchange plate 211 is usually in close contact with the surface of the battery module 22 to ensure that the heat of the battery module 22 can be efficiently transferred to the coolant and dissipated into the environment through the heat exchanger, thereby keeping the battery module within a suitable operating temperature range.

[0048] The battery module 22 is fixed to the corresponding first mounting beam 212. In some embodiments of this application, the battery module 22 and the first mounting beam 212 can be fixedly connected by bolts or by welding. However, this utility model is not limited to this. The battery module 22 and the first mounting beam 212 can also be fixedly connected by other means, as long as the battery module 22 is fixed to the corresponding first mounting beam 212.

[0049] The heat exchange plate 211, the first mounting beam 212 and the battery module 22 are assembled as independent units, forming a highly modular structure. This makes it simple and quick to repair or replace a single module unit 20 without having to disassemble the entire battery device on a large scale.

[0050] According to some embodiments of the present invention, such as Figure 2 As shown, the first mounting beam 212 extends along the second direction, and the battery module 22 is fixedly connected to the first mounting beam 212, so that the first mounting beam 212 can support the battery module 22 in the second direction, which helps to prevent the battery module 22 from deforming or being damaged when subjected to external forces.

[0051] According to some embodiments of the present invention, such as Figure 2 As shown, the heat exchanger 21 may include a plurality of first mounting beams 212, and the plurality of first mounting beams 212 of each heat exchanger 21 are arranged sequentially at intervals along a third direction, with the first direction, the second direction and the third direction being perpendicular.

[0052] The heat exchanger 21 may include multiple first mounting beams 212. In some embodiments of this application, the heat exchanger 21 may include two, three, four, or other numbers of first mounting beams 212. However, this invention is not limited to this, and the heat exchanger 21 may also include other numbers of first mounting beams 212, as long as the heat exchanger 21 includes multiple first mounting beams 212. The multiple first mounting beams 212 of each heat exchanger 21 are arranged sequentially at intervals along a third direction, and the first mounting beams 212 are fixedly connected to the battery module 22. This allows the multiple first mounting beams 212 to uniformly support the battery module 22, thereby improving the stability and reliability of the battery module 22.

[0053] According to some embodiments of this utility model, multiple module units 20 can be arranged sequentially along a second direction, with the first and second directions perpendicular. This arrangement makes the entire battery device more compact and efficient. The module units 20 typically have the same size and interface. The sequential arrangement of multiple module units 20 along the second direction facilitates orderly wiring between the module units 20 for a cleaner, more organized appearance. It also makes it easier to design a heat dissipation system to ensure effective heat dissipation between the module units 20, helping to maintain the battery device's operating temperature within a safe range and improving the stability and reliability of the battery device.

[0054] According to some embodiments of this utility model, the mounting base 10 includes a second mounting beam 11, and the heat exchange component 21 of each module unit 20 is detachably disposed on the second mounting beam 11. In some embodiments of this application, the heat exchange component 21 and the second mounting beam 11 can be fixedly connected by bolts, or the heat exchange component 21 and the second mounting beam 11 can be connected by snap-fit. However, this utility model is not limited to this, and the heat exchange component 21 and the second mounting beam 11 can also be detachably connected by other means, as long as the heat exchange component 21 of each module unit 20 is detachably disposed on the second mounting beam 11. This configuration realizes the modular design of each module unit 20, so that each module unit 20 can be installed, disassembled and replaced as an independent component, which greatly improves the maintainability and scalability of the battery device. When a module unit 20 fails or needs to be upgraded, it can be handled separately without affecting the operation of the entire battery device.

[0055] The detachable design makes the installation and removal of the module unit 20 more convenient. Operators can easily fix the module unit 20 to the second mounting beam 11 or remove it from the mounting base 10, which not only improves work efficiency but also reduces the difficulty and cost of operation.

[0056] Furthermore, the first mounting beam 212 is fixedly assembled with the battery module 22, and the second mounting beam 11 is fixedly assembled with the heat exchange plate 211 and the housing. Along the third direction, both ends of the heat exchange plate 211 can have mounting points evenly arranged along the second direction, so that the heat exchange plate 211 can be fixedly connected to the housing, enabling it to function as described above. Figure 3 The uniformly distributed assembly points of the battery module assembly 100 and the housing, as shown, can improve the rigidity and stability of the battery device.

[0057] The battery device according to an embodiment of the present invention includes: a housing; a battery module assembly 100, wherein the battery module assembly 100 is installed in the housing, the battery module assembly 100 is the same as the battery module assembly 100 described above, a mounting base 10 is fixed to the housing, and a heat exchange component 21 is detachably fixed to the housing, so that each module unit 20 can be repaired and replaced individually, which greatly reduces the maintenance cost of the battery device and improves the reusability of the module unit 20.

[0058] The vehicle according to the present invention includes the battery device of the above embodiment, so that each module unit 20 can be repaired and replaced individually, which greatly reduces the maintenance cost of the battery device and improves the reusability of the module unit 20, thereby reducing the manufacturing cost of the vehicle.
