[0002] In related technologies, the bottom of the vehicle is usually equipped with a battery pack and various external pipelines. However, the arrangement of external pipelines will take up a lot of space at the bottom of the vehicle, which will limit the size of the battery pack and thus affect the vehicle's range. Utility Model Content

[0005] Optionally, the support beam includes interconnected beam bodies and multiple connecting portions. The connecting portions extend along the length of the beam body and have channels within them. Both ends of the connecting portions are used to connect to the external pipelines so that the channels connect to the external pipelines.

[0013] Optionally, the pipeline includes one or more of the following: brake pipeline, fuel pipeline, refrigerant pipeline, motor coolant pipeline, air conditioning inlet and outlet water pipeline, and gas supply pipeline.

[0014] According to a second aspect of this application, a battery pack frame is provided, including a support beam as described above, wherein the support beam has a plurality of channels that pass through the support beam along the length direction of the support beam, and the plurality of channels are used to connect to external pipelines.

[0015] Optionally, the battery pack frame is used in a vehicle, and the support beam extends along the longitudinal direction of the vehicle.

Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0034] This application provides a support beam, a battery pack frame, a battery pack, and a vehicle.

[0035] Figure 1 This is a schematic diagram of the structure of one embodiment of the vehicle provided in this application. Figure 2 This is a schematic diagram of the structure of one embodiment of the battery pack provided in this application. Figure 1 and Figure 2 As shown, vehicle 1 includes a battery pack 10. The battery pack 10 may be disposed at the bottom of vehicle 1. The battery pack 10 includes a battery pack frame 100 and a battery module 140, with the battery module 140 mounted on the battery pack frame 100. The battery pack frame 100 includes a receiving cavity 110, and the battery module 140 is mounted within the receiving cavity 110 of the battery pack frame 100.

[0036] like Figures 2 to 4 As shown, the battery pack frame 100 includes a support beam 120 for connection to the vehicle frame of the vehicle 1 to secure the battery pack 10 to the vehicle frame of the vehicle 1. In some embodiments, such as Figure 3As shown, the support beam 120 is provided with multiple channels 1220, which pass through the support beam 120 along its length and are used to connect to external pipelines.

[0037] In this embodiment, multiple channels 1220 are provided within the support beam 120, extending along the length of the support beam 120 and connecting to external pipelines. When the battery pack 10 is installed in the vehicle 1, both ends of the support beam 120 can be connected to external pipelines, allowing the external pipelines to connect through the channels 1220 within the support beam 120. This allows a portion of the external pipelines to be replaced by the channels 1220 of the support beam 120, reducing the space occupied by the external pipelines and allowing the battery pack 10 frame to occupy more space. This means the battery pack 10 frame can be designed to be larger, improving its size and capacity, and ultimately increasing the range of the vehicle 1.

[0038] In some embodiments, such as Figure 2 As shown, the battery pack frame 100 can be used in vehicle 1. The support beam 120 of the battery pack frame 100 is used to connect to the frame of vehicle 1. The support beam 120 of the battery pack frame 100 can extend in the longitudinal direction of vehicle 1. Thus, the channel 1220 of the support beam 120 can replace a portion of the external pipelines extending in the longitudinal direction in vehicle 1, which helps to further reduce the space occupied by external pipelines.

[0039] In some embodiments, the battery pack frame 100 may include a receiving cavity 110 and two support beams 120, the receiving cavity 110 for receiving the battery module 140, and the two support beams 120 located on both sides of the receiving cavity 110. This allows for a further increase in the number of connecting portions 122 to replace more external pipes, thereby further reducing the space occupied by external pipes.

[0040] Specifically, two support beams 120 are located on both sides of the receiving cavity 110 along the width direction of the vehicle 1. The two support beams 120 extend along the length direction of the vehicle 1, respectively.

[0041] Of course, the support beam 120 in this embodiment can be used not only for the battery pack frame 100, but also for other devices with external pipelines.

[0042] In some embodiments, such as Figure 3 and Figure 4As shown, the support beam 120 can include interconnected beam bodies 121 and multiple connecting portions 122. These connecting portions 122 extend along the length of the beam bodies 121, and each connecting portion 122 has a channel 1220. Both ends of the connecting portion 122 are used to connect to external pipelines, allowing the channel 1220 to communicate with external pipelines. This makes the formation of the channel 1220 within the support beam 120 more convenient.

[0043] It should be noted that a channel 1220 may be provided in the connecting part 122, or multiple channels 1220 may be provided in the channel part 12.

[0044] In some embodiments, such as Figure 4 As shown, the beam body 121 can include a cavity 1210 extending along its length, with multiple connecting portions 122 located within the cavity 1210. Thus, the beam body 121 can protect the multiple connecting portions 122, reducing the risk of deformation or even damage to the connecting portions 122 due to impact or compression.

[0045] In some embodiments, such as Figure 4 As shown, the cavity 1210 of the beam body 121 can include multiple mutually isolated sub-cavities 1211, with each sub-cavity 1211 extending along the length of the beam body 121. At least two connecting portions 122 are located within different sub-cavities 1211. This allows at least two connecting portions 122 to be isolated from each other, reducing the risk that damage to one connecting portion 122 could affect the other connecting portions 122.

[0046] It should be noted that a portion of the connecting part 122 can be located within one sub-cavity 1211 of the beam body 121, while another portion can be located within another sub-cavity 1211 of the beam body 121. Alternatively, each connecting part 122 can be located within a different sub-cavity 1211 of the beam body 121. Of course, the latter can further improve the isolation effect on each connecting part 122.

[0047] The beam body 121 has multiple partitions 123 within its cavity 1210. The partitions 123 extend along the length of the beam body 121. The two side edges of the partitions 123 connect to the inner surface of the cavity 1210 of the beam body 121, thereby dividing the cavity 1210 of the beam body 121 into multiple sub-cavities 1211. The partitions 123 also strengthen the beam body 121, which helps improve the structural stability of the supporting beam 120.

[0048] In some embodiments, such as Figure 4As shown, the support beam 120 may include a reinforcing rib 124 connected to the beam body 121. The reinforcing rib 124 extends along the length of the beam body 121, and the connecting portion 122 is connected to the reinforcing rib 124. Thus, the reinforcing rib 124 can increase the strength of the beam body 121, thereby improving the structural stability of the support beam 120. Furthermore, by connecting the connecting portion 122 to the reinforcing rib 124, the strengths of the reinforcing rib 124 and the connecting portion 122 can be mutually reinforced, thereby improving the overall structural strength of the connecting portion 122 and the support beam 120.

[0049] The reinforcing rib 124 may include two reinforcing plates 1241, which are located on both sides of the corresponding connecting portion along the radial direction of the channel 1220. One edge of the reinforcing plate 1241 is connected to the corresponding connecting portion 122, and the other edge of the reinforcing plate 1241 is connected to the beam body 121. This further enhances the reinforcement effect on the connecting portion 122.

[0050] Alternatively, the beam body 121 can include a cavity 1210 extending along its length, with the reinforcing rib 124 located within the cavity 1210. This allows the connecting portion 122, which communicates with the reinforcing rib 124, to be located within the cavity 1210 of the beam body 121, thus protecting the connecting portion 122 through the beam body 121. Furthermore, by placing the reinforcing rib 124 within the cavity 1210 of the beam body 121, both edges of the reinforcing rib 124 can be connected to the beam body 121, improving the connection strength between the reinforcing rib 124 and the beam body 121, thereby enhancing the reinforcing effect of the reinforcing rib 124 on the beam body 121 and increasing the overall strength of the supporting beam 120.

[0051] In some embodiments, the connecting portion 122 and the beam body 121 can be integrated into one structure. This allows for a higher connection strength between the connecting portion 122 and the beam body 121, which is beneficial for improving the structural strength of both the beam body 121 and the connecting portion 122.

[0052] Specifically, the connecting part 122 and the reinforcing rib 124 are an integral structure. The reinforcing rib 124 and the beam body 121 are an integral structure. The partition 123 and the reinforcing rib 124 intersect each other. The partition 123 and the reinforcing rib 124 are an integral structure. The partition 123 and the beam body 121 are an integral structure.

[0053] In some embodiments, such as Figure 3As shown, connectors 130 can be provided at both ends of the support beam 120. These connectors 130 are used to connect with external pipelines, so that the channel 1220 can be connected to the external pipelines. That is, the external pipelines located at both ends of the support beam 120 can be connected through the channel 1220. As a result, the support beam 120 can be connected to the external pipelines more stably, and the connection method is very convenient, which helps to improve the connection efficiency and stability of the support beam 120 and the external pipelines.

[0054] Each of the multiple connecting parts 122 may have a connector 130 at both ends. Each of the two ends of each connecting part 122 is connected to a different external pipeline through the connector 130, so that multiple external pipelines at one end of the support beam 120 are connected to multiple external pipelines at the other end of the support beam 120 through corresponding channels 1220.

[0055] In some embodiments, the external piping connected to the support beam 120 may include one or more of the following: brake piping, fuel piping, refrigerant piping, motor coolant piping, air conditioning inlet / outlet water piping, and air supply piping. That is, a portion of one or more of the brake piping, fuel piping, refrigerant piping, coolant piping, and air supply piping can be replaced by the connecting portion 122 of the support beam 120. Naturally, the more types of external piping the support beam 120 replaces, the less space the external piping occupies, allowing for a larger battery pack 10 design.

[0056] In some embodiments, the external pipeline may include a braking pipeline, and both ends of the connecting portion 122 of the support beam 120 are connected to the braking pipeline so that the braking pipeline is connected through the channel 1220.

[0057] Among them, such as Figure 4 As shown, the braking lines can include a left rear wheel brake line and a right rear wheel brake line. The left rear wheel brake line is used for braking the left rear wheel of vehicle 1, and the right rear wheel brake line is used for braking the right rear wheel of vehicle 1. The connecting part 122 includes a first connecting part 1221 and a second connecting part 1222. The two ends of the first connecting part 1221 are connected to the two sections of the left rear wheel brake line respectively, so that the two sections of the left rear wheel brake line are connected through the channel 1220 of the first connecting part 1221. The two ends of the second connecting part 1222 are connected to the two sections of the right rear wheel brake line respectively, so that the two sections of the right rear wheel brake line are connected through the channel 1220 of the second connecting part 1222.

[0058] like Figure 3As shown, first connectors 1301 can be provided at both ends of the first connecting part 1221, and the two first connectors 1301 are connected to the two sections of the left rear wheel brake lines one-to-one, so that the two sections of the left rear wheel brake lines are connected through the channel 1220 of the first connecting part 1221. Second connectors 1302 can be provided at both ends of the second connecting part 1222, and the two second connectors 1302 are connected to the two sections of the right rear wheel brake lines one-to-one, so that the two sections of the right rear wheel brake lines are connected through the channel 1220 of the second connecting part 1222.

[0059] In some embodiments, the external pipeline may include a fuel pipeline, and both ends of the connecting portion 122 of the support beam 120 are connected to the fuel pipeline so that the fuel pipeline is connected through the channel 1220 of the connecting portion 122.

[0060] The fuel lines may include a supply line and a return line. The supply line supplies fuel to the engine, and the return line returns fuel from the engine to the fuel tank. The connecting portion 122 includes a third connecting portion 1223 and a fourth connecting portion 1224. The two ends of the third connecting portion 1223 are connected to two corresponding sections of the supply line, allowing the two supply lines to be connected through a channel 1220. The two ends of the fourth connecting portion 1224 are connected to two corresponding sections of the return line, allowing the two return lines to be connected through a channel 1220.

[0061] like Figure 3 and Figure 4 As shown, third connectors 1303 can be provided at both ends of the third connecting part 1223, and the two third connectors 1303 are connected to the two oil supply lines one-to-one, so that the two oil supply lines are connected through the channel 1220 of the third connecting part 1223.
