Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0039] like Figures 1 to 6 As shown, this application provides a battery module. The battery module includes a heat exchange assembly 10, a cell assembly 20, and a mounting assembly 30. The cell assembly 20 is disposed on the heat exchange assembly 10, and the length direction of the cell assembly 20 (e.g., ...) Figure 1End plates 21 are provided at both ends of the battery cell assembly 20 (in the direction indicated by the middle arrow X). The mounting assembly 30 includes at least two mounting components. Along the length of the battery cell assembly 20, at least two mounting components are disposed on the heat exchange assembly 10 and are movable relative to the heat exchange assembly 10. The at least two mounting components are located on opposite sides of the battery cell assembly 20. On the same side of the battery cell assembly 20, the end plate 21 is connected to the mounting component on the corresponding side.

[0040] Since the actual voltage and capacitance required by the battery module differ in different application scenarios, it is necessary to increase or decrease the number of cells in the cell assembly 20 according to actual needs. In the battery module provided in this application, after increasing or decreasing the number of cells, the position of the mounting component relative to the heat exchange component 10 is adjusted so that the mounting component is connected to the end plate 21 of the cell assembly 20, which ensures the universality of the original structural components of the battery module after increasing or decreasing the number of cells, and helps to save production costs.

[0041] In this embodiment, by providing a mounting component 30 on the heat exchange assembly 10, and the mounting component 30 including at least two mounting parts that can move relative to the heat exchange assembly 10, the battery module can be adapted to different sizes of battery cell components 20 by adjusting the position of the mounting parts. The same heat exchange assembly 10 can accommodate multiple battery cell components 20 of different specifications. Compared with the prior art, there is no need to customize the heat exchange assembly 10 separately for each size of battery module, thereby improving the versatility of the heat exchange assembly 10 and significantly reducing production costs. The mounting parts can move relative to the heat exchange assembly 10. When installing the battery cell component 20, the position of the mounting parts can be flexibly adjusted according to the specific size of the battery cell component 20, and then the end plate 21 is connected to the mounting parts to complete the fixation of the battery cell component 20, making installation more convenient. Furthermore, when it is necessary to replace a battery cell component 20 of different specifications, only the position of the mounting parts needs to be readjusted, without replacing the entire heat exchange assembly 10, greatly simplifying the installation process of the battery cell component 20 and improving production and maintenance efficiency. By mounting the battery cell assembly 20 on the heat exchange assembly 10, the heat exchange assembly 10 can effectively exchange heat with the battery cell assembly 20, enabling the battery module to operate safely and efficiently within a suitable temperature range, thus ensuring the performance and lifespan of the battery module. Simultaneously, the connection between the end plate 21 and the mounting components ensures the stable mounting of the battery cell assembly 20 on the heat exchange assembly 10, further ensuring the stability and reliability of the heat exchange effect, which is beneficial for maintaining the stable performance of the battery module.

[0042] like Figure 2As shown in Figure 5, in one embodiment, the mounting component is connected to the heat exchange assembly 10 via a position adjustment structure and is movable relative to the heat exchange assembly 10. The position adjustment structure allows for precise positional adjustment of the mounting component on the heat exchange assembly 10. This battery module can accurately move the mounting component to a suitable position according to the size requirements of different cell components 20, ensuring that the cell components 20 can be precisely installed on the heat exchange assembly 10, guaranteeing installation accuracy and stability, thereby better realizing the overall performance of the battery module and improving the battery module's adaptability to cell components 20 of different specifications. Regardless of changes in the length or thickness of the cell components 20, this embodiment can accurately adapt through the position adjustment structure, expanding the applicability of the battery module.

[0043] The position adjustment structure includes a first through hole, a second through hole, and a fastener. The first through hole is along the height direction of the cell assembly 20 (e.g., ...). Figure 1The first through hole (in the direction indicated by the middle arrow Y) is provided through the mounting component. A second through hole is provided through the heat exchange component 10 along the height direction of the battery cell assembly 20. Multiple second through holes are provided, spaced apart along the length direction of the battery cell assembly 20. Fasteners are detachably connected to the heat exchange component 10 through the first and second through holes to adjust the position of the mounting component relative to the heat exchange component 10. To adjust the position of the mounting component, first unlock the fasteners to separate the mounting component from the heat exchange component 10, then move the mounting component to a preset mounting position on the heat exchange component 10 and align the first through hole on the mounting component with the second through hole at the preset mounting position. The fasteners then pass through the first and second through holes to fix the mounting component to the heat exchange component 10. Specifically, the fasteners can be bolts. Connection and position adjustment are achieved by the fasteners passing through the first through hole of the mounting component and the second through hole of the heat exchange component 10, making the operation simple and direct. By simply loosening the fasteners, the mounting component can be moved to the appropriate position along the length of the cell assembly 20 as needed, and then the fasteners can be tightened to secure it. This allows for quick and efficient adjustment of the mounting component's position relative to the heat exchange assembly 10, facilitating easy and rapid adaptation to cell assemblies 20 of different sizes. The heat exchange assembly 10 has multiple second through holes spaced apart along the length of the cell assembly 20, providing multiple precise positioning points for the mounting component. Depending on the specific dimensions of the cell assembly 20, appropriate second through holes can be selected and aligned with the first through holes, connected by fasteners, thereby achieving relatively precise position adjustment. This meets the installation accuracy requirements of different specifications of cell assemblies 20, ensuring the overall performance and stability of the battery module. Fasteners passing through the first and second through holes detachably connect the mounting component to the heat exchange assembly 10. This connection method provides reliable fastening force, ensuring that the mounting component will not loosen or shift during battery module operation. Even when the battery module is subjected to external forces such as vibration and impact, the connection stability can be maintained, thus ensuring the relative position between the cell assembly 20 and the heat exchange assembly 10 is fixed, which is beneficial to improving the safety and reliability of the battery module. Adjusting the position of the mounting component relative to the heat exchange assembly 10 through the first through hole, the second through hole, and fasteners eliminates the need for complex mechanical transmission devices or high-precision positioning mechanisms, resulting in lower manufacturing costs. The structure is also convenient for production and assembly, improving production efficiency and further reducing production costs. Multiple first and second through holes can be spaced along the width direction of the cell assembly 20, which helps to enhance the stability of the mounting component.

[0044] Alternatively, the mounting component can be fixed to the heat exchange assembly 10 by welding. When it is necessary to adjust the position of the mounting component, the mounting component and the heat exchange assembly 10 can be separated by gas cutting, plasma cutting or laser cutting, so as to adjust the position of the mounting component.

[0045] Alternatively, two sliding grooves can be provided on the heat exchange component 10, with the two sliding grooves respectively located in the width direction of the cell assembly 20 (e.g., Figure 1 On opposite sides of the direction indicated by the middle arrow Z, the slide grooves extend along the length of the cell assembly 20, and the mounting components are connected between the two slide grooves and can slide along the length of the slide grooves.

[0046] In one embodiment, along the length of the cell assembly 20, the end plates 21 on opposite sides of the cell assembly 20 are respectively a first end plate 211 and a second end plate 212. The mounting components include a first end connecting beam 31 and a second end connecting beam 32. Along the length of the cell assembly 20, both the first end connecting beam 31 and the second end connecting beam 32 are disposed on the heat exchange assembly 10 and located on opposite sides of the cell assembly 20. The first end connecting beam 31 is connected to the bottom end of the first end plate 211, and the second end connecting beam 32 is connected to the bottom end of the second end plate 212. The connection between the first end connecting beam 31 and the first end plate 211, and the connection between the second end connecting beam 32 and the second end plate 212, provides stable support for the cell assembly 20 from the bottom. When the battery module is subjected to external forces, such as vibration or impact, the first end connecting beam 31 and the second end connecting beam 32 can effectively disperse the external forces, reducing the possibility of the cell assembly 20 shaking or displacing, thereby improving the structural stability of the entire battery module and ensuring that the battery module can operate safely and reliably under various working conditions. Both the first end connecting beam 31 and the second end connecting beam 32 can be moved along the length of the cell assembly 20 by a position adjustment structure to change the position of the first end connecting beam 31 and the second end connecting beam 32 relative to the heat exchange assembly 10.

[0047] Along the length of the battery cell assembly 20, the battery cell assembly 20 comprises multiple sets, which are arranged at intervals. The mounting components also include an intermediate connecting beam 33. The intermediate connecting beam 33 is disposed on the heat exchange assembly 10 and located between two adjacent battery cell assemblies 20. On two adjacent battery cell assemblies 20, the bottom end of the second end plate 212 of the first battery cell assembly 20 and the bottom end of the first end plate 211 of the second battery cell assembly 20 are both connected to the intermediate connecting beam 33. When the multiple sets of battery cell assemblies 20 are arranged at intervals, the end plate 21 of the first set of battery cell assemblies 20 furthest from the last set of battery cell assemblies 20 is connected to the first end connecting beam 31, and the end plate 21 of the last set of battery cell assemblies 20 furthest from the first set of battery cell assemblies 20 is connected to the second end connecting beam 32. That is, the first end connecting beam 31 and the second end connecting beam 32 are located on both sides of the overall end of the multiple sets of battery cell assemblies 20, and an intermediate connecting beam 33 is provided between two adjacent battery cell assemblies 20. Multiple battery cell modules 20 are arranged at intervals and connected to the bottom ends of the end plates 21 of adjacent battery cell modules 20 by an intermediate connecting beam 33. This allows for the rational arrangement of multiple battery cell modules 20 within a limited space and stable fixation of the battery cell modules 20 to the heat exchange assembly 10. This effectively utilizes the internal space of the battery module, making the battery module structure more compact and contributing to increased energy density, meeting the high energy density requirements of the equipment. The intermediate connecting beam 33 connects adjacent battery cell modules 20 together, forming a unified structure and increasing the structural strength and stability of the battery module. When the battery module is subjected to external forces, the intermediate connecting beam 33 can transfer and disperse stress, reducing the external force borne by individual battery cell modules 20, lowering the risk of damage to the battery cell modules 20, and improving the reliability and durability of the entire battery module. The interval arrangement of multiple battery cell modules 20 forms an air circulation channel, which is beneficial for heat dissipation. Meanwhile, the intermediate connecting beam 33 does not obstruct the flow of air between the cell components 20, and the connection between the connecting beam and the end plate 21 also helps to transfer the heat generated by the cell components 20 to the heat exchange component 10 for heat dissipation, further optimizing the heat dissipation performance of the battery module, ensuring that the battery module remains within a suitable temperature range during operation, and improving the performance and lifespan of the battery.

[0048] The intermediate connecting beam 33 can be moved along the length of the cell assembly 20 via a position adjustment structure to change its position relative to the heat exchange assembly 10. When installing cell assemblies 20 of different sizes on the heat exchange assembly 10, by adjusting the positions of the first end connecting beam 31, the second end connecting beam 32, and the intermediate connecting beam 33 relative to the heat exchange assembly 10, cell assemblies 20 of different sizes can be installed on the heat exchange assembly 10, improving the versatility and application range of the battery module.

[0049] like Figures 4 to 5As shown, in one embodiment, a first connecting portion 41 is provided on the first end connecting beam 31, the second end connecting beam 32, and the intermediate connecting beam 33. A second connecting portion 42, which mates with the first connecting portion 41, is provided at the bottom end of the first end plate 211 and the bottom end of the second end plate 212. The first connecting portion 41 and the second connecting portion 42 cooperate with each other, enabling rapid and precise positioning and connection between the first end connecting beam 31, the second end connecting beam 32, and the intermediate connecting beam 33 and the end plate 21. During installation, workers can quickly complete assembly by connecting the corresponding first connecting portions 41 and the second connecting portions 42, reducing adjustment and alignment time during installation and improving assembly efficiency.

[0050] The first connecting part 41 and the second connecting part 42 each include a groove, and the other includes a protrusion that mates with the groove. The protrusion is embedded in the groove. The mating of the protrusion and the groove enables precise positioning between the first end connecting beam 31, the second end connecting beam 32, the intermediate connecting beam 33, and the end plate 21. During installation, the protrusion can only be inserted into the groove in a specific direction, ensuring the accuracy of the connection and avoiding misalignment or deviation that may occur during installation, thus improving the assembly accuracy of the entire battery module. The protrusion is tightly embedded in the groove, which can restrict the relative movement between the cell assembly 20 and the heat exchange assembly 10 in multiple directions. This tight fit can effectively resist external forces such as vibration and impact generated during the operation of the battery module, reduce loosening and wear of the connection parts, thereby improving the stability and reliability of the connection and ensuring the structural integrity of the battery module. The connection method of the protrusion being embedded in the groove is relatively simple. During installation, the protrusion is simply aligned with the groove and inserted, which is convenient and quick, and helps to improve assembly efficiency. Disassembly is also relatively easy, without complicated tools or operating procedures, making it convenient for maintenance, repair, or replacement of parts of the battery module.

[0051] Alternatively, through holes can be provided on the first end connecting beam 31, the second end connecting beam 32, the intermediate connecting beam 33, and the end plate 21 along the height direction of the cell assembly 20, and the connecting column passes through the through holes to limit the cell assembly 20 on the heat exchange assembly 10.

[0052] In one embodiment, the heat exchange assembly 10 includes a support frame component 11 and a heat exchange component. The heat exchange component includes a first plate and a second plate. The second plate is connected to the support frame component 11, and a heat exchange channel is provided on the side of the second plate facing away from the support frame component 11. The first plate covers the second plate and closes the top surface of the heat exchange channel. The side of the first plate facing away from the second plate is connected to the mounting assembly 30 and the cell assembly 20. The heat exchange channel provides a flow path for the coolant, effectively carrying away the heat generated by the cell assembly 20. The combined structure of the first and second plates allows the heat exchange channel to form a closed space, ensuring stable flow of the coolant within the channel and sufficient heat exchange with the cell assembly 20, thereby improving heat dissipation efficiency, maintaining the cell assembly 20 within a suitable operating temperature range, and contributing to improved battery module performance and lifespan. The second plate, connected to the support frame component 11, provides stable support for the entire heat exchange assembly 10 and also enhances the stability of the connection between the heat exchange assembly 10 and the mounting assembly 30 and the cell assembly 20. The support frame component 11 can bear the weight of the battery cell assembly 20 and the mounting assembly 30, ensuring the reliability and stability of the heat exchange assembly 10 and reducing poor heat dissipation or other problems caused by structural loosening. The side of the first plate facing away from the second plate is connected to the mounting assembly 30 and the battery cell assembly 20, ensuring that the heat generated by the battery cell assembly 20 can be transferred to the first plate more quickly, which is beneficial for faster heat dissipation of the battery cell assembly 20. An inlet 12 and an outlet 13 are respectively provided at both ends of the heat exchange channel.

[0053] like Figure 6As shown, the support frame component 11 includes a first support beam 111 and a second support beam 112. The first support beam 111 comprises two beams, which are spaced apart on opposite sides of the cell assembly 20 in the width direction. The two ends of the second support beam 112 are perpendicularly connected to the sides of the two first support beams 111 that are close to each other. Multiple second support beams 112 are spaced apart along the length direction of the first support beams 111. The side of the second plate facing away from the first plate is connected to the upper surface of the first support beam 111. The two first support beams 111, spaced apart on opposite sides of the cell assembly 20 in the width direction, provide stable lateral support for the cell assembly 20, effectively preventing the cell assembly 20 from swaying or shifting in the width direction. Multiple second support beams 112 are vertically connected between two first support beams 111 and spaced apart along the length of the first support beams 111, forming a stable frame structure. This greatly enhances the overall strength and stability of the support frame component 11, enabling it to withstand the weight of the cell assembly 20 and ensuring the reliability of the entire battery module structure. The even distribution of the multiple second support beams 112 ensures uniform support for the second plate and the heat exchange components and cell assembly 20 connected to it. This avoids excessive local stress due to uneven support, reducing the risk of component deformation or damage, ensuring uniform stress on all components within the battery module, and extending the overall lifespan of the battery module. In this embodiment, the two ends of the second support beams 112 are vertically connected to the sides of the two first support beams 111 that are close to each other. This ensures that the upper surface of the first support beams 111 is relatively flat, allowing the second plate to fit more closely to the upper surface of the first support beams 111, ensuring good stability of the heat exchange components.

[0054] On the other hand, this application embodiment also provides a battery pack, which includes a battery case 50 and the aforementioned battery module. The battery case 50 is fitted onto the heat exchange assembly 10, and the cell assembly 20 and the mounting assembly 30 are located inside the battery case 50. The outer edge of the battery case 50 may be provided with a bent flange, which is fixedly connected to the upper surface of the first plate. This battery pack includes all the technical effects of the aforementioned battery module. Since the technical effects of the battery module have been described in detail above, they will not be repeated here.

[0055] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0056] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0057] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
