It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the application described herein can, for example, be implemented in an order other than that illustrated or described herein.

[0039] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0040] As mentioned in the background technology, the threshold beam assembly in the related art includes a threshold beam and a battery pack connected to the threshold beam through FDS and sealant. When assembling the entire vehicle, the threshold beam assembly is connected to the vehicle body floor through a connecting plate, and the entire vehicle is sealed through a sealing structure.

[0041] However, the above assembly method makes the connection between the components more complicated, resulting in low integration of the entire vehicle.

[0042] In view of this, an embodiment of the present application provides a sill beam structure and a vehicle. The sill beam structure is provided with a sill beam body, a sealing member and multiple connecting members. The sill beam body includes a connecting portion and a load-bearing portion arranged in sequence. When assembling the entire vehicle, the connecting portion is located above the battery pack of the vehicle and the load-bearing portion is located on the side of the battery pack to protect the battery pack from collision force. The connecting portion is connected to the battery pack through various connecting members, and the sealing assembly is abutted between the connecting portion and the battery pack to seal the gap between the connecting portion and the battery pack. In this way, the upper cover of the battery pack can be used as the bottom plate of the vehicle body, which simplifies the connection between the various components and is conducive to improving the integration of the entire vehicle.

[0043] Hereinafter, the present application will be described in detail with reference to the accompanying drawings and specific embodiments.

[0044] See Figures 1 to 3An embodiment of the present application provides a threshold beam structure, including a threshold beam body 100, a sealing assembly 200 and a plurality of connectors 300; the threshold beam body 100 includes a connecting portion 110 and a bearing portion 120 arranged in sequence, the connecting portion 110 is used to be located above the battery pack 400 of the vehicle, the bearing portion 120 is used to be located on the side of the battery pack 400, and the connecting portion 110 is used to be connected to the battery pack 400 through each connector 300; the sealing assembly 200 is used to abut between the connecting portion 110 and the battery pack 400 to seal the gap between the connecting portion 110 and the battery pack 400.

[0045] It should be noted that the rocker beam of the embodiment of the present application can be applied to pure electric vehicles, and can also be applied to hybrid vehicles with a battery pack 400 structure, and the embodiment of the present application does not limit this.

[0046] It should also be noted that the battery pack 400 of the embodiment of the present application is a battery pack 400 integrated into the vehicle using cell-to-body (CTB) technology. The CTB technology is used to combine the upper cover of the battery pack 400 with the vehicle body floor, so that the battery is not only an energy storage unit, but also participates in the mechanical structure of the entire vehicle as part of the vehicle body structure, thereby improving the integration of the entire vehicle; by reducing intermediate structural parts, CTB technology can better utilize the space inside the vehicle, so that more batteries can be installed in the same volume, thereby improving the cruising range of electric vehicles.

[0047] During vehicle assembly, the rocker beam structure of the embodiment of the present application positions the connecting portion 110 above the battery pack 400 and connects it to the battery pack 400 via the connector 300. This ensures a secure and reliable connection between the connecting portion 110 and the battery pack 400, while facilitating assembly and disassembly and maintenance. Furthermore, the load-bearing portion 120 is positioned to the side of the battery pack 400, enhancing the rocker beam structure's lateral compressive strength. In the event of a side impact, the load-bearing portion 120 collapses first, effectively dispersing and absorbing the impact force. This improves vehicle safety in side collisions and protects the battery pack 400 and occupants.

[0048] In a specific implementation, the carrying portion 120 is located on the side of the battery pack 400. Figure 2 The left side of the X direction shown, that is, the carrying portion 120 is located on one side of the battery pack 400 along the vehicle width direction, by providing a plurality of connectors 300, so that when the connecting portion 110 is located above the battery pack 400, since the battery pack 400 and the connecting portion 110 are both along the length direction of the vehicle, Figure 2 The Y direction shown has corresponding dimensions, and the plurality of connecting members 300 are arranged along Figure 1The Y direction shown, that is, the length direction of the connecting portion 110 is arranged at intervals, so that the connecting portion 110 is connected to the battery pack 400 at the corresponding position through each connecting member 300, thereby ensuring that the relative position of the connecting portion 110 and the battery pack 400 remains stable, making the connection between the two more firm and reliable.

[0049] The sill beam structure is equipped with a sealing assembly 200, which is used to abut between the connecting portion 110 and the battery pack 400. This ensures a tight seal between the connecting portion 110 and the battery pack 400, preventing moisture and dust intrusion, protecting the internal structure of the battery pack 400, and extending battery life. Furthermore, the sealing assembly 200 provides a certain degree of cushioning during minor collisions or bumps, reducing direct impact on the battery pack 400 and improving safety.

[0050] In summary, the sill beam structure of the embodiment of the present application is provided with a sill beam body 100, a sealing member and a plurality of connecting members 300. The sill beam body 100 includes a connecting portion 110 and a load-bearing portion 120 which are sequentially arranged. When assembling the entire vehicle, the connecting portion 110 is located above the battery pack 400 and the load-bearing portion 120 is located to the side of the battery pack 400 to protect the battery pack 400 from collision force. The connecting portion 110 is connected to the battery pack 400 through each connecting member 300, and the sealing assembly 200 is abutted between the connecting portion 110 and the battery pack 400 to seal the gap between the connecting portion 110 and the battery pack 400. In this way, the upper cover of the battery pack 400 can be used as the vehicle body floor, which simplifies the connection between the various components and helps to improve the integration of the entire vehicle.

[0051] In some examples, the connecting portion 110 and the carrying portion 120 are integrally formed by aluminum extrusion.

[0052] In this way, the production process is simplified, the steps of welding and adding profiles are reduced, and the process complexity of the threshold beam body 100 is reduced, which is conducive to reducing manufacturing costs and improving production efficiency and manufacturing integration.

[0053] See Figure 3 In some embodiments, the connecting portion 110 includes a first connecting section 111, the load-bearing portion 120 is connected to the first connecting section 111, the first connecting section 111 is used to be located on the side of multiple seat cross beams 420 of the battery pack 400, and there is a distance between the first connecting section 111 and each seat cross beam 420; the sealing assembly 200 includes multiple first seals 210, the connecting members 300 and the first seals 210 are alternately arranged in sequence along the extension direction of the first connecting section 111, the first seals 210 are used to be arranged one by one opposite to the seat cross beams 420, the first connecting section 111 is used to be connected to the battery pack 400 through each connecting member 300, and the first seal 210 is used to abut between the first connecting section 111 and the battery pack 400.

[0054] It can be understood that the extending direction of the first connecting section 111 is consistent with the length direction of the vehicle described in the above embodiment.

[0055] Specifically, considering that the threshold beam structure of the embodiment of the present application is connected to the battery pack 400, so that the battery pack 400 is integrated into the vehicle using CTB technology, the upper cover of the battery pack 400 is used as the vehicle body floor. When the entire vehicle is assembled, the seat cross beams 420 will be integrated on the upper cover of the battery pack 400. By setting the first connecting section 111 to be located on the side of the seat cross beam 420 and having a spacing between it and each seat cross beam 420, when the vehicle is side-collided, the first connecting section 111 is forced to collapse and transmits the collision force to the seat cross beam 420 through the spacing. The existence of the spacing can effectively disperse and absorb the collision force, which is beneficial to improving the overall structural stability of the battery pack 400 and improving the safety of the vehicle.

[0056] Exemplarily, the battery pack 400 may include a battery pack body 410 and multiple seat beams 420 connected to the battery pack 400, such that the connecting portion 110 is located above the battery pack body 410, so that the first connecting section 111 is located on the side of the seat beam 420, and the load-bearing portion 120 is located on the side of the battery pack body 410.

[0057] In specific implementation, by setting multiple first seals 210, the connecting member 300 and the first seal 210 are alternately set in sequence along the extension direction of the first connecting section 111, so that the setting position of the first seal 210 and the setting position of the connecting member 300 avoid each other, thereby avoiding the first seal 210 from affecting the fixing effect of the connecting member 300 on the first connecting section 111 and the battery pack 400, and avoiding the connecting member 300 from affecting the sealing effect of the first seal 210 on the gap between the first connecting section 111 and the battery pack 400.

[0058] It should be noted that after the first connecting section 111 is connected to the battery pack 400 through each connecting member 300, the gap between the structure of the first connecting section 111 located between two adjacent connecting members 300 and the battery pack 400 is sealed by the first sealing member 210. However, there is still a gap between the structure of the first connecting section 111 located at the position of the connecting member 300 and the battery pack 400. Therefore, in order to further improve the sealing effect between the first connecting section 111 and the battery pack 400, refer to Figure 4In some examples, the connecting portion 110 further includes a plurality of second connecting segments 112 connected to the first connecting segment 111, and each second connecting segment 112 and the load-bearing portion 120 are located on opposite sides of the first connecting segment 111; each second connecting segment 112 is spaced apart along the extension direction of the first connecting segment 111 so that the second connecting segments 112 are opposite to the connecting member 300 one by one, and the second connecting segment 112 is used to be located between two adjacent seat cross beams 420.

[0059] The sealing assembly 200 further includes a plurality of second sealing members 220 . The second sealing members 220 correspond one-to-one to the second connecting segments 112 . The second sealing members 220 are configured to abut between the corresponding second connecting segments 112 and the battery pack 400 .

[0060] Specifically, by arranging each second connecting section 112 and the load-bearing portion 120 on opposite sides of the first connecting section 111, that is, each second connecting section 112 is located on the side of the first connecting section 111 facing the seat cross beam 420, each second connecting section 112 is spaced apart along the extension direction of the first connecting section 111 so that the second connecting sections 112 and the connecting members 300 are opposite to each other one by one. In this way, the second sealing members 220 correspond to the second connecting sections 112 one by one, and the second sealing members 220 are used to abut between the corresponding second connecting sections 112 and the battery pack 400, so that the second sealing members 220 seal the gap between the structure at the position of the connecting member 300 on the first connecting section 111 and the battery pack 400, thereby achieving effective coverage of the sealing assembly 200 as a whole between the sill beam body 100 and the battery pack 400, which is beneficial to improving the sealing performance of the entire vehicle.

[0061] The embodiment of the present application does not limit the specific structure of the second connecting section 112 . For example, the second connecting section 112 may be a plate-shaped structure. This simplifies the structure and helps reduce the difficulty of processing the sill beam body 100 .

[0062] See Figures 3 to 5 In the specific example, the first connecting section 111 has a first connecting surface 1112, and the second connecting section 112 has a second connecting surface 1121. The first connecting surface 1112 and the second connecting surface 1121 are both used to be arranged opposite to the battery pack 400. The first connecting surface 1112 is used to connect to the battery pack 400 through each connecting member 300. The first connecting surface 1112 abuts the first sealing member 210, and the second connecting surface 1121 abuts the second sealing member 220; the first connecting surface 1112 and the second connecting surface 1121 are located on the same horizontal plane.

[0063] Such a configuration enables the first seal 210 to be tightly abutted between the first connecting surface 1112 and the battery pack 400, and the second seal 220 to be tightly abutted between the second connecting surface 1121 and the battery pack 400, which is beneficial to improving the fit and ensuring that the contact surfaces between the sealing assembly 200 and the battery pack 400 and between the sealing assembly 200 and the connecting part 110 are uniform, thereby avoiding poor sealing problems caused by unevenness.

[0064] At the same time, the horizontal plane design enables the pressure on the first sealing member 210 and the second sealing member 220 to be evenly distributed, thereby reducing local stress concentration, improving the sealing effect, and extending the service life.

[0065] Furthermore, it can be understood that since the first connecting surface 1112 and the second connecting surface 1121 are located on the same horizontal plane, it is beneficial to achieve universal interchangeability of the first sealing component 210 and the second sealing component 220.

[0066] In some embodiments, a first distance is located between the side of the second connecting segment 112 facing away from the first connecting segment 111 and the first connecting segment 111 , and the first distance is greater than the spacing, wherein the spacing is 3 mm-7 mm.

[0067] Among them, by setting the first distance to be greater than the spacing between the first connecting section 111 and each seat cross beam 420, on the one hand, since the connecting member 300 and the first sealing member 210 are alternately arranged, and the first sealing member 210 is arranged one-to-one opposite to the seat cross beam 420, the second connecting section 112 arranged one-to-one opposite to the connecting member 300 is located between two adjacent seat cross beams 420, which can avoid the position of the second connecting section 112 and the position of the seat cross beam 420 from interfering with each other; on the other hand, the design of the first distance is used to provide more sufficient space for the second sealing member 220, so that it can better abut between the second connecting surface 1121 and the battery pack 400, avoiding the problem of poor sealing due to too small a space, and further improving the sealing effect.

[0068] For example, the spacing may be set to 3 mm, 5 mm, 7 mm, etc.

[0069] See Figure 4 and Figure 5 In some examples, the first connecting section 111 has a first energy absorption cavity 1111, the connecting member 300 includes a bolt 310 and a nut 320 matching the bolt 310, and a connecting hole 1113 connected to the first energy absorption cavity 1111 is opened on the first connecting surface 1112. The bolt 310 is used to sequentially pass through the avoidance hole 430 and the connecting hole 1113 of the battery pack 400 and to be sleeved with the nut 320.

[0070] Specifically, by providing a first energy-absorbing cavity 1111 in the first connecting section 111, on the one hand, the first energy-absorbing cavity 1111 can absorb energy during a vehicle collision, thereby reducing the impact on the seat crossbeam 420 located on the side of the first connecting section 111 and improving the safety of the vehicle in a side collision.

[0071] On the other hand, the first energy absorption cavity 1111 provides a placement space for the connector 300. For example, the connector 300 includes a bolt 310 and a nut 320. When in use, the bolt 310 is passed through the avoidance hole 430 of the battery pack 400 and the connection hole 1113 on the first connection surface 1112 in sequence, so that part of the bolt 310 is placed in the accommodating cavity and the nut 320 in the accommodating cavity is sleeved. In this way, part of the bolt 310 is hidden by the first energy absorption cavity 1111, so that the assembly layout of the sill beam body 100 and the battery pack 400 is more reasonable. Furthermore, through the connection method of the bolt 310 and the nut 320, the assembly of the first connecting section 111 and the battery pack 400 is simpler, and the connection strength and stability between the first connecting section 111 and the battery pack 400 can be ensured.

[0072] See Figures 4 to 6 In some embodiments, the supporting portion 120 has a plurality of second energy absorbing cavities 121 arranged in an array, and the volume of each second energy absorbing cavity 121 decreases sequentially along the direction in which the supporting portion 120 moves away from the connecting portion 110 .

[0073] When the vehicle collides, the second energy-absorbing cavity 121 farthest from the connection portion 110 absorbs the collision force first, and then the external force is transmitted to the adjacent second energy-absorbing cavity 121 and then to the second energy-absorbing cavity 121 closest to the connection portion 110 .

[0074] By setting the volume of each second energy absorption cavity 121 to decrease successively along the direction of the load-bearing portion 120 away from the connecting portion 110, that is, the cavity wall thickness of the second energy absorption cavity 121 farthest from the connecting portion 110 can be designed to be greater than the cavity wall thickness of the second energy absorption cavity 121 closest to the connecting portion 110, thereby ensuring that the load-bearing portion 120 as a whole has good structural strength, and utilizing each second energy absorption cavity 121 to form a step-by-step energy absorption effect, thereby reducing the impact of the collision force on the battery pack 400.

[0075] Continue reading Figure 5 and Figure 6 For example, one of the plurality of second energy absorbing cavities 121 is used to place the cooling water pipe 500 of the vehicle, and one of the plurality of second energy absorbing cavities 121 is provided with a support rib 122, which is used to support the cooling water pipe 500 to limit the displacement of the cooling water pipe 500.

[0076] In this way, the second energy absorbing cavity 121 and the supporting ribs 122 provided therein provide a hidden installation space and a fixing structure for the cooling water pipe 500 , thereby saving the layout space of the vehicle power system.

[0077] See Figure 2 An embodiment of the present application also provides a vehicle, including a battery pack 400 and a sill beam structure in any of the above embodiments connected to the battery pack 400.

[0078] The overall structure and working principle of the threshold beam structure are the same as those in the aforementioned embodiment and will not be described in detail here.

[0079] In some examples, the battery pack 400 includes a battery pack body 410 and a plurality of seat cross beams 420 connected to the battery pack body 410, wherein the plurality of seat cross beams 420 are arranged at intervals along the extension direction of the battery pack body 410; the number of sill beam structures is two, and the connecting portions 110 of the two sill beam structures are respectively connected to the opposite sides of the battery pack body 410; wherein the extension direction of the battery pack body 410 is consistent with the extension direction of the first connecting section 111 of the sill beam structure.
