Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] As described in the background section, to effectively manage battery thermal conductivity, battery modules typically have liquid cooling pipes at their bottom. Each end of the liquid cooling pipe is equipped with a collector pipe to collect and distribute coolant. The two collector pipes are connected via an inlet pipe and an outlet pipe, respectively, forming a complete coolant circulation path. Currently, the collector pipes are located on the outside of the module end plate. However, this layout not only increases the overall size of the battery module and occupies too much space in the battery casing, but also increases manufacturing costs, ultimately affecting the integration efficiency of the battery module.

[0046] Based on this, please refer to Figures 1-6 The present invention provides a battery module 100, a battery pack 1100, and a new energy vehicle 1000, which can effectively improve the technical problems mentioned above. That is, it can reduce the overall volume of the module, save space in the battery casing 200, thereby reducing manufacturing costs and improving module integration efficiency.

[0047] It should be noted that the first direction mentioned below refers to... Figures 1-6 The X direction is shown in the figure, and the second direction is... Figures 1-6 The Y direction shown in the figure, the third direction is Figures 1-6 The Z direction is shown in the diagram. The following will provide a detailed description of the battery module 100, battery pack 1100, and new energy vehicle 1000.

[0048] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of the new energy vehicle 1000 provided in this embodiment, combined with... Figure 1 The new energy vehicle 1000 includes a battery pack 1100 and a vehicle body 1200. The battery pack 1100 is installed on the vehicle body 1200 to provide electrical energy to the vehicle body 1200 so as to realize the various functions of the vehicle body 1200.

[0049] Please refer to Figure 2 , Figure 2 This is a structural schematic diagram of the battery pack 1100 provided in this embodiment, combined with... Figure 2 The battery pack 1100 includes a battery module 100 and a battery housing 200. The battery module 100 is disposed inside the battery housing 200. The battery module 100 serves as the energy source for the battery pack 1100 and can provide electrical energy to the vehicle body 1200.

[0050] Please refer to Figure 3 and Figure 4 , Figure 3 This is a first-view structural diagram of the battery module 100 provided in this embodiment. Figure 4 This is a structural schematic diagram of the battery module 100 provided in this embodiment from a second perspective. (Combined with...) Figure 3 and Figure 4 The battery module 100 includes a module body 10 and a liquid cooling component 30. The liquid cooling component 30 can conduct heat to the module body 10 to ensure that the module body 10 operates at a suitable temperature.

[0051] For details, please refer to Figure 5 and Figure 6 , Figure 5 for Figure 4 A magnified view of a portion of point A in the middle. Figure 6 for Figure 4 A magnified view of a section at point B, combined with... Figures 3-6 The module body 10 includes a first module end plate 11, a second module end plate 12, and a battery pack 13. The first module end plate 11 and the second module end plate 12 are respectively disposed on opposite sides of the battery pack 13, and a first mounting space 21 is formed between the first module end plate 11 and the battery pack 13, and a second mounting space 22 is formed between the second module end plate 12 and the battery pack 13. The liquid cooling assembly 30 includes a first liquid collecting pipe 31, a second liquid collecting pipe 32, and a liquid cooling pipe 33. The liquid cooling pipe 33 is disposed at the bottom of the battery pack 13, and the first liquid collecting pipe 31 and the second liquid collecting pipe 32 are respectively connected to both ends of the liquid cooling pipe 33. The first liquid collecting pipe 31 is disposed in the first mounting space 21, and the second liquid collecting pipe 32 is disposed in the second mounting space 22.

[0052] In other words, by setting the first mounting space 21 and the second mounting space 22, the first liquid collecting pipe 31 and the second liquid collecting pipe 32 can be installed and accommodated respectively, so that the first liquid collecting pipe 31 and the second liquid collecting pipe 32 are both located inside the module end plate, that is, in the reserved space between the first module end plate 11 and the battery pack 13, and in the reserved space between the second module end plate 12 and the battery pack 13, respectively. It is easy to understand that compared with the existing method of placing the module end plate externally, the overall volume of the battery module 100 can be reduced, thereby saving the installation space for subsequent installation of the battery module 100 in the battery housing 200, thereby reducing manufacturing costs and improving the integration efficiency of the module.

[0053] To improve the energy density of the battery pack 1100, in this embodiment, there are multiple battery packs 13, which are spaced apart along a first direction. Each battery pack 13 includes multiple battery cells 131, which are arranged sequentially along a second direction. A first module end plate 11 and a second module end plate 12 are spaced apart along the second direction. Similarly, there are also multiple liquid cooling pipes 33, which are spaced apart along the first direction and correspond one-to-one with each of the multiple battery packs 13. The liquid cooling pipes 33 are in contact with the bottom of the multiple battery cells 131. Both a first liquid collecting pipe 31 and a second liquid collecting pipe 32 extend along the first direction, with the first liquid collecting pipe 31 connected to one end of each of the multiple liquid cooling pipes 33 and the second liquid collecting pipe 32 connected to the other end of each of the multiple liquid cooling pipes 33. The first direction and the second direction form an angle.

[0054] It is understandable that each battery pack 13 has a liquid cooling pipe 33 at the bottom of multiple cells 131, so as to ensure that each cell 131 can conduct heat and exchange heat. Furthermore, this arrangement of the battery pack 13 with the first liquid collecting pipe 31, the second liquid collecting pipe 32 and the liquid cooling pipe 33 makes the overall structure of the battery module 100 compact, further reducing the volume and saving space.

[0055] Furthermore, to better install and secure the battery pack 13, in this embodiment, the module body 10 also includes a plurality of separators 14. The plurality of separators 14 are spaced apart along a first direction, and each separator 14 extends along a second direction. A battery pack 13 is provided between two adjacent separators 14. A plurality of liquid cooling pipes 33 are spaced apart from the plurality of separators 14 along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0056] like Figure 3As shown, by setting multiple separators 14, each battery pack 13 can be fixed by installing separators 14 on both sides of the first direction, thereby improving the installation stability of multiple battery packs 13; and the separation between two adjacent battery packs 13 by a separator 14 can also make the overall structure of the battery module 100 compact, further reducing the volume and saving space.

[0057] Optionally, the liquid cooling assembly 30 also includes an inlet pipe 34 and an outlet pipe 35. The inlet pipe 34 is connected to the first liquid collection pipe 31, and the outlet pipe 35 is connected to the second liquid collection pipe 32, so as to facilitate connection with the coolant supply device through the inlet pipe 34 and the outlet pipe 35, so as to realize the circulation of coolant inside the liquid cooling assembly 30 and improve the heat exchange effect.

[0058] Please continue to combine Figures 3-6 Specifically, the first module end plate 11 includes a first fixing part 111, a first connecting part 112, and a first clearance part 113 connected in sequence. The first fixing part 111 is disposed on the side of the first connecting part 112 near the battery pack 13, and the first fixing part 111 abuts against the battery pack 13. The first clearance part 113 is disposed on the side of the first connecting part 112 away from the battery pack 13, and the first clearance part 113 is spaced apart from the battery pack 13. A first mounting space 21 is formed between the first clearance part 113, the first connecting part 112, and the battery pack 13.

[0059] like Figure 5 As shown, the first fixing part 111 and the first clearance part 113 both extend along a third direction, and the first connecting part 112 extends along a second direction. During conventional assembly of the battery module 100, the first fixing part 111 can be understood as extending upwards, the first clearance part 113 as extending downwards, and the first connecting part 112 as extending in the left-right direction. By providing the first fixing part 111, one side of the battery pack 13 can be abutted and fixed. Specifically, in this embodiment, the first fixing part 111 abuts against the upper middle part of the battery pack 13, improving the installation stability and structural compactness of the battery pack 13. The first clearance portion 113 is spaced apart from the battery pack 13, and can cooperate with the first connecting portion 112 to provide a reserved installation space for the first liquid collecting pipe 31. It also facilitates one end of the liquid cooling pipe 33 to pass through the bottom of the battery pack 13 and extend into the first installation space 21, and connect with the first liquid collecting pipe 31. In addition, the first clearance portion 113 can also protect the first liquid collecting pipe 31 and the liquid cooling pipe 33.

[0060] Similarly, to improve the installation stability and structural compactness of the battery pack 13, and to facilitate the installation and protection of the liquid cooling pipe 33 and the second liquid collecting pipe 32, in this embodiment, the second module end plate 12 includes a second fixing part 121, a second connecting part 122, and a second clearance part 123 connected in sequence. The second fixing part 121 is disposed on the side of the second connecting part 122 near the battery pack 13, and the second fixing part 121 abuts against the battery pack 13. The second clearance part 123 is disposed on the side of the second connecting part 122 away from the battery pack 13, and the second clearance part 123 is spaced apart from the battery pack 13, forming a second installation space 22 between the second clearance part 123, the second connecting part 122, and the battery pack 13.

[0061] Combination Figure 3 and Figure 5 In order to further limit one side of the battery pack 13, improve the installation stability of the battery pack 13, and reduce wear on one side of the battery pack 13, the battery module 100 also includes a first limiting member 41. The first limiting member 41 is disposed between the first fixing part 111 and the battery pack 13, and simultaneously abuts against both the first fixing part 111 and the battery pack 13.

[0062] Combination Figure 3 and Figure 6 Similarly, in order to limit the other side of the battery pack 13, further improve the installation stability of the battery pack 13, and reduce wear on the other side of the battery pack 13, the battery module 100 also includes a second limiting member 42. The second limiting member 42 is disposed between the second fixing part 121 and the battery pack 13, and simultaneously abuts against the second fixing part 121 and the battery pack 13.

[0063] It should be noted that in this embodiment, the first limiting member 41 can be connected and fixed to the first module end plate 11, while the second limiting member 42 can be connected and fixed to the second module end plate 12, thereby improving the overall structural strength of the battery module 100.

[0064] Please continue to combine Figure 5 The first clearance portion 113, the first liquid collecting pipe 31, and the battery pack 13 are arranged sequentially at intervals. The first limiting member 41 has a first extension portion 411 at one end near the liquid cooling pipe 33. The first extension portion 411 abuts against the battery pack 13 and is spaced apart from the first liquid collecting pipe 31. It is easy to understand that in this embodiment, by providing the first extension portion 411, the lower middle part of one side of the battery pack 13 can also be abutted and fixed, thereby improving the overall fastening effect of the battery pack 13; at the same time, the first extension portion 411 is spaced apart from the first liquid collecting pipe 31, which can avoid interference between the two, ensure the flow of coolant in the first liquid collecting pipe 31, and reduce vibration and noise.

[0065] It should be noted that in this embodiment, when one end of the liquid cooling pipe 33 enters the first mounting space 21 through the bottom of the battery pack 13, a bend is required to facilitate connection with the first liquid collecting pipe 31. Therefore, in order to better avoid the bend of the liquid cooling pipe 33 and the first liquid collecting pipe 31 and improve the service life of both, the thickness of the first extension 411 gradually decreases along the direction close to the liquid cooling pipe 33, that is, as... Figure 5 As shown, the first extension 411 is inclined on the side near the first liquid collection pipe 31 and has an inclined surface.

[0066] Please continue to combine Figure 6 The second clearance part 123, the second liquid collecting pipe 32, and the battery pack 13 are arranged sequentially at intervals. The second limiting member 42 has a second extension part 421 at one end near the liquid cooling pipe 33. The second extension part 421 abuts against the battery pack 13 and is spaced apart from the second liquid collecting pipe 32. Similarly, by providing the second extension part 421, the lower middle part of the other side of the battery pack 13 can also be abutted and fixed, thereby improving the overall fastening effect of the battery pack 13. Furthermore, the spaced arrangement of the second extension part 421 and the second liquid collecting pipe 32 can also avoid interference between the two, thereby ensuring the flow of coolant in the second liquid collecting pipe 32 and reducing vibration and noise.

[0067] Similarly, in order to better avoid the bends in the liquid cooling pipe 33 and the second manifold 32, and to improve the service life of both, the thickness of the second extension 421 gradually decreases along the direction close to the liquid cooling pipe 33, that is, as... Figure 6 As shown, the second extension 421 is inclined on the side near the second liquid collection pipe 32 and has an inclined surface.

[0068] It should be noted that during transportation or when the battery module 100 is actually installed on the vehicle body 1200 and moves with the vehicle body 1200, it may experience up-and-down vibration or shaking. Therefore, in order to better protect the first liquid collecting pipe 31 and prevent the first liquid collecting pipe 31 from directly contacting the first connecting part 112 when shaking, the battery module 100 also includes a first protective member 51, which is disposed on the side of the first liquid collecting pipe 31 near the first connecting part 112.

[0069] Similarly, in order to better protect the second liquid collection tube 32, the battery module 100 also includes a second protective member 52, which is disposed on the side of the second liquid collection tube 32 near the second connection portion 122.

[0070] It should be noted that both the first protective component 51 and the second protective component 52 can be structures with elastic buffering function, which can absorb vibration energy and further improve the protection of the first liquid collecting pipe 31 and the second liquid collecting pipe 32, thereby improving their service life.

[0071] In summary, the embodiments of this utility model provide a battery module 100, a battery pack 1100, and a new energy vehicle 1000. The battery module 100 includes a module body 10 and a liquid cooling assembly 30. The module body 10 includes a first module end plate 11, a second module end plate 12, and a battery pack 13. The first module end plate 11 and the second module end plate 12 are respectively disposed on opposite sides of the battery pack 13, and a first mounting space 21 is formed between the first module end plate 11 and the battery pack 13, and a second mounting space 22 is formed between the second module end plate 12 and the battery pack 13. The liquid cooling assembly 30 includes a first liquid collecting pipe 31, a second liquid collecting pipe 32, and a liquid cooling pipe 33. The liquid cooling pipe 33 is disposed at the bottom of the battery pack 13, and the first liquid collecting pipe 31 and the second liquid collecting pipe 32 are respectively connected to both ends of the liquid cooling pipe 33. The first liquid collecting pipe 31 is disposed in the first mounting space 21, and the second liquid collecting pipe 32 is disposed in the second mounting space 22. By providing the first mounting space 21 and the second mounting space 22, the first liquid collecting pipe 31 and the second liquid collecting pipe 32 can be installed and accommodated respectively, so that both the first liquid collecting pipe 31 and the second liquid collecting pipe 32 are located inside the module end plate, that is, in the reserved space between the first module end plate 11 and the battery pack 13, and in the reserved space between the second module end plate 12 and the battery pack 13, respectively. It is easy to understand that compared to the existing method of placing the module end plate externally, this reduces the overall volume of the battery module 100, thereby saving installation space for subsequent installation of the battery module 100 within the battery casing 200, thus reducing manufacturing costs and improving module integration efficiency.

[0072] The battery pack 1100 includes a battery module 100, which has all the functions and benefits of the battery module 100.

[0073] The new energy vehicle 1000 includes a battery pack 1100, which has all the functions and benefits of the battery pack 1100.
