DETAILED DESCRIPTION

[0020] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0021] A sealing assembly 7 for a vehicle according to an embodiment of the present application will be described below with reference to FIG. 1 to FIG. 4 .

[0022] As shown in FIG. 1-FIG . 4 , at least a portion of the sealing assembly 7 is adapted to be located between the vehicle body 6 and the battery pack 5 of the vehicle to seal the gap between the vehicle body 6 and the battery pack 5 .

[0023] As some optional embodiments of the present application, the vehicle body 6 has a mounting notch 61, which can penetrate the vehicle body 6 along the height direction of the vehicle (i.e., the Z direction shown in Figure 4). The battery pack 5 is provided in the vehicle body 6, and the battery pack 5 blocks the mounting notch 61. The battery pack 5 is configured to constitute at least a portion of the floor of the vehicle body assembly 100. As some optional embodiments of the present application, at least a portion of the structure of the battery pack 5 can be located within the mounting notch 61, and the upper cover of the battery pack 5 can be configured to constitute at least a portion of the floor of the vehicle body assembly 100. By providing the vehicle body 6 with the mounting notch 61 and configuring the battery pack 5 to constitute at least a portion of the floor of the vehicle body assembly 100, part of the floor of the traditional vehicle body can be omitted, thereby reducing the weight of the vehicle body 6, facilitating the lightweight design of the vehicle and improving the vehicle's cruising range.

[0024] At least a portion of the sealing assembly 7 is located between the vehicle body 6 and the battery pack 5. In some optional embodiments of the present application, at least a portion of the sealing assembly 7 is located between the vehicle body 6 and the battery pack 5. In some optional embodiments of the present application, the sealing assembly 7 is located between the vehicle body 6 and the battery pack 5. The sealing assembly 7 is capable of sealing the gap between the vehicle body 6 and the battery pack 5.

[0025] It should be noted that because the battery pack 5 is configured to form at least a portion of the floor of the vehicle body assembly 100, a gap may exist between the battery pack 5 and the main body 6. This gap between the battery pack 5 and the main body 6 allows the passenger compartment to communicate with the outside world through the gap, resulting in passengers experiencing excessive noise and vibration. It also allows large amounts of dust to enter the passenger compartment through the gap between the battery pack 5 and the main body 6, affecting passenger comfort. Sealing the gap between the main body 6 and the battery pack 5 with the sealing assembly 7 improves the airtightness of the passenger compartment, thereby reducing the noise and vibration experienced by passengers and preventing large amounts of dust from entering the passenger compartment through the gap between the battery pack 5 and the main body 6, thus improving vehicle comfort.

[0026] The sealing assembly 7 includes: a first sealing member 77 and a second sealing member 78, the first sealing member 77 has a first sealing portion 771 and a connecting portion 772, wherein the connecting portion 772 is located on the side of the first sealing portion 771 close to the second sealing member 78, along the thickness direction of the sealing assembly 7 (i.e., the Z direction shown in Figure 4), at least part of the connecting portion 772 is located above the second sealing member 78, and the connecting portion 772 located above the second sealing member 78 is connected to the second sealing member 78.

[0027] It can be understood that since the first seal 77 includes a first sealing portion 771 and a connecting portion 772, and at least a portion of the connecting portion 772 is located above the second seal 78 and connected to the second seal 78, when it is necessary to match vehicle models with different wheelbases, it is only necessary to adaptively adjust or replace the first seal 77 or the second seal 78 to enable the sealing assembly 7 to match vehicle models with different wheelbases.

[0028] For example, the length of the first seal portion 771 in the longitudinal direction of the vehicle (i.e., the X direction as shown in FIG1 ) can be changed. This allows the vehicle to be compatible with vehicles of different wheelbases by simply replacing the first seal 77, thereby achieving universal use of the second seal 78. Alternatively, the length of the second seal 78 in the longitudinal direction of the vehicle (i.e., the X direction as shown in FIG1 ) can be changed. This allows the vehicle to be compatible with vehicles of different wheelbases by simply replacing the second seal 78, thereby achieving universal use of the first seal 77. Alternatively, the first seal 77 and the second seal 78 can be appropriately separated or brought closer together (i.e., relatively far apart or relatively close) in the longitudinal direction of the vehicle (i.e., the X direction as shown in FIG1 ), while ensuring that at least a portion of the connecting portion 772 is located above the second seal 78. This allows universal use of the first seal 77 and the second seal 78, thereby achieving universal use of the entire sealing assembly 7. However, this method will slightly reduce the sealing performance of the sealing assembly 7 compared to replacing either the first seal 77 or the second seal 78.

[0029] As some optional embodiments of the present application, the number of first seals 77 can be set to two, the two first seals 77 can be arranged opposite to and spaced apart along the width direction of the vehicle (i.e., the Y direction shown in Figure 1), and the two first seals 77 can be extended along the length direction of the vehicle (i.e., the X direction shown in Figure 1). In other words, the two first seals 77 can be the left seal 74 and the right seal 76 respectively, and the second seal 78 can be approximately regarded as a structure extending along the width direction of the vehicle (i.e., the Y direction shown in Figure 1) (the two ends of the second seal 78 extend along the length direction of the vehicle), and the two connecting parts 772 of the two first seals 77 can be respectively connected to the two ends of the second seal 78.

[0030] As some optional embodiments of the present application, as shown in Figures 1 to 3, the number of second seals 78 can be set to two, the two second seals 78 can be arranged opposite to and spaced apart along the width direction of the vehicle (i.e., the Y direction shown in Figure 1), and the two second seals 78 can be extended along the length direction of the vehicle (i.e., the X direction shown in Figure 1). In other words, the two second seals 78 can be a left seal 74 and a right seal 76, respectively, and, along the width direction of the vehicle, both ends of the first seal 77 have a connecting portion 772. The first seal 77 can be approximately regarded as a structure extending along the width direction of the vehicle (the two ends of the first seal 77 extend along the length direction of the vehicle), and the two second seals 78 are connected to the two connecting portions 772 at one end close to the first seal 77.

[0031] As some optional embodiments of the present application, as shown in FIG4 , a portion of the connecting portion 772 may be located above the second sealing member 78. As some optional embodiments of the present application, the entire connecting portion 772 may be located above the second sealing member 78. As some optional embodiments of the present application, as shown in FIG4 , the connecting portion 772 and the first sealing portion 771 may be parallel to each other.

[0032] Therefore, by designing the first seal 77 to have a structure with a first sealing portion 771 and a connecting portion 772, and making at least part of the connecting portion 772 located above the second seal 78 and connected to the second seal 78, when it is necessary to match vehicle models with different wheelbases, it is only necessary to adaptively adjust or replace the first seal 77 or the second seal 78 to enable the sealing assembly 7 to match vehicle models with different wheelbases, thereby improving the versatility of the sealing assembly 7, helping to reduce the production cost of the vehicle, and ensuring the sealing performance of the sealing assembly 7.

[0033] In some embodiments of the present application, a sealing layer may be provided between the connecting portion 772 and the second sealing member 78 along the thickness direction of the sealing assembly 7. Specifically, a sealing layer may be provided between the connecting portion 772 located above the second sealing member 78 and the second sealing member 78.

[0034] As some optional embodiments of the present application, the sealing layer can be but not limited to rubber type, resin type, oil-based type, wet air vulcanized type, chemical vulcanized type sealant, etc. The sealant has viscosity. By arranging the sealant between the connecting part 772 located above the second seal 78 and the second seal 78, the connecting part 772 and the second seal 78 can be bonded together by the sealant. In addition, the sealant has a sealing effect, which can effectively improve the sealing performance of the sealing assembly 7, which is beneficial to improving the ride comfort of the vehicle.

[0035] As some optional embodiments of the present application, the sealing layer can be a flexible seal (such as foam), and foam can be arranged between the connecting portion 772 located above the second seal 78 and the second seal 78. Then, the connecting portion 772 is connected to the second seal 78 by means of but not limited to screwing, riveting, clamping, etc., so that the foam can be squeezed between the connecting portion 772 and the second seal 78, thereby effectively improving the sealing performance of the sealing assembly 7, which is beneficial to improving the ride comfort of the vehicle.

[0036] In some embodiments of the present application, as shown in FIG4 , along the thickness direction of the sealing assembly 7 (i.e., the Z direction shown in FIG4 , i.e., the height direction of the vehicle), the sealing assembly 7 is adapted to be located above the battery pack 5. That is, the battery pack 5 can be disposed below the sealing assembly 7, and the lower surface of the first sealing portion 771 and the lower surface of the second sealing member 78 are both adapted to seal with the battery pack 5. As some optional embodiments of the present application, the upper surface of the battery pack 5 can be sealed with the lower surface of the first sealing portion 771 and the lower surface of the second sealing member 78. This arrangement can reasonably position the sealing assembly 7 and the battery pack 5 relative to each other, which is conducive to improving the sealing effect of the sealing assembly 7.

[0037] In some embodiments of the present application, as shown in FIG4 , the lower surface of the first sealing portion 771 and the lower surface of the second sealing member 78 can be coplanar. As some optional embodiments of the present application, the upper surface of the battery pack 5 can be configured as a sealing surface, which can align with the lower surfaces of the first sealing portion 771 and the second sealing member 78. It is understood that if the sealing surface is parallel to a horizontal plane, then the lower surfaces of the first sealing portion 771 and the second sealing member 78 are both parallel to the horizontal plane, and the lower surfaces of the first sealing portion 771 and the second sealing member 78 are coplanar. If the sealing surface is at an angle to the horizontal plane, then the lower surfaces of the first sealing portion 771 and the second sealing member 78 are both at an angle to the horizontal plane, and the lower surfaces of the first sealing portion 771 and the second sealing member 78 are coplanar, and the angles between the sealing surface and the horizontal plane, the angle between the lower surface of the first sealing portion 771 and the horizontal plane, and the angle between the lower surface of the second sealing member 78 and the horizontal plane are the same. By making the lower surface of the first sealing portion 771 and the lower surface of the second sealing member 78 coplanar, the sealing effect of the sealing assembly 7 is improved.

[0038] In some embodiments of the present application, as shown in FIG4 , the first sealing member 77 may further include a connecting segment 773, which may be connected between the first sealing portion 771 and the connecting portion 772, so that the first sealing portion 771 and the connecting portion 772 are staggered along the thickness direction of the sealing assembly 7. Specifically, an end of the connecting segment 773 close to the first sealing portion 771 may be connected to the first sealing portion 771, and an end of the connecting segment 773 close to the connecting portion 772 may be connected to the connecting portion 772.

[0039] In some optional embodiments of the present application, the connecting section 773 can be a straight section, and an angle is formed between the connecting section 773 and the connecting portion 772, and between the connecting section 773 and the first sealing portion 771, so that the first sealing portion 771 and the connecting portion 772 are staggered along the thickness direction of the sealing assembly 7. In other words, the connecting section 773 can be an inclined straight section. In some optional embodiments of the present application, the connecting section 773 can also be an arcuate section, which can also cause the first sealing portion 771 and the connecting portion 772 to be staggered along the thickness direction of the sealing assembly 7.

[0040] As for the first sealing portion 771 and the connecting portion 772 being staggered along the thickness direction of the sealing assembly 7, it can be understood as setting a plane that is perpendicular to the length direction of the vehicle (i.e., the X direction shown in Figure 1), and the orthographic projection of the first sealing portion 771 on the plane and the orthographic projection of the connecting portion 772 on the plane do not completely overlap, or the orthographic projection of the first sealing portion 771 on the plane and the orthographic projection of the connecting portion 772 on the plane do not have an overlapping area.

[0041] As some optional embodiments of the present application, as shown in Figure 4, the lower surface of the connecting portion 772 can be higher than the lower surface of the first sealing portion 771. It can be understood that in an embodiment where the sealing surface of the battery pack 5 is parallel to the horizontal plane, the lower surface of the first sealing portion 771 and the lower surface of the second sealing member 78 are both parallel to the horizontal plane, and the lower surface of the first sealing portion 771 and the lower surface of the second sealing member 78 are coplanar, the lower surface of the connecting portion 772 is made higher than the lower surface of the first sealing portion 771, so that the lower surface of the first sealing portion 771 and the lower surface of the second sealing member 78 are both parallel to and coplanar with the horizontal plane. Such a setting is conducive to improving the sealing effect of the sealing assembly 7, thereby helping to improve the ride comfort of the vehicle.

[0042] As some optional embodiments of the present application, the first sealing member 77 may be an integrally formed member, which can reduce the difficulty of producing the first sealing member 77 and improve the production efficiency of the first sealing member 77 .

[0043] In some embodiments of the present application, as shown in FIG4 , a gap space 79 may be defined between the first sealing portion 771 and the second sealing member 78 along the length direction of the vehicle (i.e., the X direction shown in FIG1 ). A viscous material layer 80 may be disposed within the gap space 79. It should be noted that at least a portion of the gap space 79 is located below the connecting section 773.

[0044] Specifically, as some optional embodiments of the present application, the entire gap space 79 can be located below the connecting section 773. In this embodiment, the end of the second seal 78 close to the first sealing portion 771 and the end of the connecting portion 772 close to the first sealing portion 771 are aligned in the thickness direction of the sealing assembly 7 (i.e., the Z direction shown in Figure 4). In other words, along the length direction of the vehicle (i.e., the X direction shown in Figure 1), the distance between the end of the second seal 78 close to the first sealing portion 771 and the first sealing portion 771 is equal to the distance between the end of the connecting portion 772 close to the first sealing portion 771 and the first sealing portion 771.

[0045] As some optional embodiments of the present application, a portion of the gap space 79 may be located below the connecting section 773, and another portion of the gap space 79 may be located below the connecting portion 772. In this embodiment, along the length direction of the vehicle (i.e., the X direction shown in Figure 1), the distance between the end of the second seal 78 close to the first sealing portion 771 and the first sealing portion 771 is greater than the distance between the end of the connecting portion 772 close to the first sealing portion 771 and the first sealing portion 771.

[0046] Among them, the viscous material layer 80 is composed of a viscous material, which can be but not limited to rubber type, resin type, oil-based type, wet air vulcanized type, chemical vulcanized type sealant, etc. By arranging the viscous material layer 80 in the gap space 79, the sealing performance of the sealing component 7 can be effectively improved.

[0047] In some embodiments of the present application, as shown in FIG4 , the lower surface of the viscous material layer 80 can be coplanar with the lower surface of the first sealing portion 771. As some optional embodiments of the present application, the lower surface of the viscous material layer 80 can be made coplanar with the lower surface of the first sealing portion 771 by scraping. As some optional embodiments of the present application, the lower surface of the viscous material layer 80, the lower surface of the first sealing portion 771, and the lower surface of the second sealing member 78 can all be parallel to the horizontal plane, and the lower surface of the viscous material layer 80, the lower surface of the first sealing portion 771, and the lower surface of the second sealing member 78 can be coplanar. Such an arrangement can more effectively improve the sealing performance of the sealing assembly 7 and can effectively ensure the watertight seal between the vehicle body 6 and the battery pack 5.

[0048] In some embodiments of the present application, as shown in Figure 4, along the length direction of the vehicle (i.e., the X direction shown in Figure 1), the distance between the end of the second sealing member 78 close to the first sealing portion 771 and the end of the connecting portion 772 close to the first sealing portion 771 is A, and A can satisfy the relationship: 0mm≤A≤5mm, that is, A can be but not limited to any value between 0mm and 5mm, for example, A can be but not limited to 0mm, 1mm, 2mm, 3mm, 4mm, 5mm, etc., such a setting can make the distance between the end of the second sealing member 78 close to the first sealing portion 771 and the end of the connecting portion 772 close to the first sealing portion 771 reasonable, thereby ensuring the sealing performance of the sealing assembly 7, which is conducive to improving the ride comfort of the vehicle.

[0049] In some embodiments of the present application, the number of first seals 77 can be set to two. The two first seals 77 can be arranged opposite each other and spaced apart along the width direction of the vehicle (i.e., the Y direction as shown in FIG1 ). Furthermore, the two first seals 77 can extend along the length direction of the vehicle (i.e., the X direction as shown in FIG1 ). In other words, the two first seals 77 can be a left seal 74 and a right seal 76 , respectively. The second seal 78 can be roughly regarded as a structure extending along the width direction of the vehicle (i.e., the Y direction as shown in FIG1 ) (with both ends of the second seal 78 extending along the length direction of the vehicle). The two connecting portions 772 of the two first seals 77 can be respectively connected to the two ends of the second seal 78. This arrangement can seal the gap between the vehicle body 6 and the battery pack 5, improve the airtightness of the passenger compartment, and thus improve the ride comfort of the vehicle.

[0050] In some embodiments of the present application, as shown in Figures 1-3, the number of second seals 78 can be set to two. The two second seals 78 can be arranged opposite each other and spaced apart along the width direction of the vehicle (i.e., the Y direction shown in Figure 1). Moreover, the two second seals 78 can extend along the length direction of the vehicle (i.e., the X direction shown in Figure 1). In other words, the two second seals 78 can be a left seal 74 and a right seal 76, respectively. In addition, along the width direction of the vehicle, both ends of the first seal 77 have a connecting portion 772. The first seal 77 can be roughly regarded as a structure extending along the width direction of the vehicle (the two ends of the first seal 77 extend along the length direction of the vehicle), and the two second seals 78 are connected to the two connecting portions 772 at their ends near the first seal 77. This arrangement can seal the gap between the vehicle body 6 and the battery pack 5, improve the airtightness of the passenger compartment, and thus improve the ride comfort of the vehicle.

[0051] In some embodiments of the present application, as shown in FIG4 , the sealing assembly 7 may further include a flexible seal 55 , which is adapted to be interposed between the battery pack 5 and the sealing assembly 7 . Specifically, the flexible seal 55 may be interposed between the lower surface of the first sealing portion 771 and the upper surface of the battery pack 5 , and between the lower surface of the second seal 78 and the upper surface of the battery pack 5 . By providing the flexible seal 55 between the battery pack 5 and the sealing assembly 7 , the flexible seal 55 is squeezed by the battery pack 5 and the sealing assembly 7 , providing a good sealing effect.

[0052] A vehicle body assembly 100 according to an embodiment of the present application will be described below with reference to FIG. 1 to FIG. 4 .

[0053] As shown in FIG. 1-FIG . 4 , the vehicle body assembly 100 according to an embodiment of the present application includes: a vehicle body 6 , a battery pack 5 , a sealing assembly 7 and a front panel 621 .

[0054] The vehicle body 6 has a mounting notch 61, which can penetrate the vehicle body 6 along the height direction of the vehicle (i.e., the Z direction shown in FIG. 4 ). The battery pack 5 is disposed on the vehicle body 6 and obstructs the mounting notch 61. The battery pack 5 is configured to constitute at least a portion of the floor of the vehicle body assembly 100. In some optional embodiments of the present application, at least a portion of the structure of the battery pack 5 can be located within the mounting notch 61, and the upper cover of the battery pack 5 can be configured to constitute at least a portion of the floor of the vehicle body assembly 100. By providing the vehicle body 6 with the mounting notch 61 and configuring the battery pack 5 to constitute at least a portion of the floor of the vehicle body assembly 100, part of the floor of a conventional vehicle body can be eliminated, thereby reducing the weight of the vehicle body 6, facilitating a lightweight design of the vehicle and improving the vehicle's range.

[0055] Along the length of the vehicle body 6 (i.e., the X-direction shown in FIG1 ), the dash panel 621 is located in front of the sealing assembly 7 and is connected to the sealing assembly 7 to form an annular structure. At least a portion of the dash panel 621 is located between the vehicle body 6 and the battery pack 5. In some optional embodiments of the present application, a portion of the dash panel 621 is located between the vehicle body 6 and the battery pack 5. In some optional embodiments of the present application, the dash panel 621 is located between the vehicle body 6 and the battery pack 5. The dash panel 621 can seal the gap between the vehicle body 6 and the battery pack 5.

[0056] By sealing the gap between the vehicle body 6 and the battery pack 5 through the sealing assembly 7 and the front panel 621, the airtightness of the passenger compartment can be improved, thereby reducing the noise and vibration felt by passengers in the passenger compartment, and also preventing a large amount of dust from entering the passenger compartment through the gap between the battery pack 5 and the vehicle body 6, which is beneficial to improving the ride comfort of the vehicle.

[0057] Furthermore, by connecting the sealing assembly 7 and the dash panel 621 to form an annular structure, the gap between the vehicle body 6 and the battery pack 5 can be reliably sealed.

[0058] Furthermore, by designing the first seal 77 to have a structure with a first sealing portion 771 and a connecting portion 772, and making at least part of the connecting portion 772 located above the second seal 78 and connected to the second seal 78, when it is necessary to match vehicle models with different wheelbases, only the first seal 77 or the second seal 78 needs to be adaptively adjusted or replaced to enable the sealing assembly 7 to match vehicle models with different wheelbases, thereby improving the versatility of the sealing assembly 7, helping to reduce the production cost of the vehicle, and ensuring the sealing performance of the sealing assembly 7.

[0059] As some optional embodiments of the present application, the battery pack 5 can serve as the front floor of the vehicle body assembly 100 .

[0060] As a specific embodiment of the present application, as shown in Figures 1 to 3, the number of second seals 78 can be set to two, and the two second seals 78 can be arranged opposite to and spaced apart along the width direction of the vehicle (i.e., the Y direction shown in Figure 1), and the two second seals 78 can be extended along the length direction of the vehicle (i.e., the X direction shown in Figure 1). In other words, the two second seals 78 can be the left seal 74 and the right seal 76 respectively, and, along the width direction of the vehicle, both ends of the first seal 77 have a connecting portion 772, and the first seal 77 can be approximately regarded as a structure extending along the width direction of the vehicle (the two ends of the first seal 77 extend along the length direction of the vehicle), and the ends of the two second seals 78 close to the first seal 77 are respectively connected to the two connecting portions 772, and the ends of the two second seals 78 close to the front panel 621 are respectively connected to the two ends of the front panel 621. In other words, the front panel 621, the left seal 74, the first seal 77, and the right seal 76 can be connected in sequence end to end.

[0061] Specifically, one end of the dash panel 621 may be connected to one end of the left seal 74, the other end of the left seal 74 may be connected to one end of the first seal 77, the other end of the first seal 77 may be connected to one end of the right seal 76, and the other end of the right seal 76 may be connected to the other end of the dash panel 621. At least one of the left seal 74, the first seal 77, and the right seal 76 may be connected to the vehicle body 6. As some optional embodiments of the present application, the left seal 74, the first seal 77, and the right seal 76 may all be connected to the vehicle body 6.

[0062] The lower surfaces of the first seal 771, the second seal 78, and the dash panel 621 are coplanar and parallel to the horizontal plane. Furthermore, the connecting portion 772 is parallel to the first seal 771. Along the length of the vehicle (i.e., the X-direction shown in FIG1 ), a gap 79 is defined between the first seal 771 and the second seal 78. A viscous material layer 80 is disposed within this gap 79, with the lower surface of the viscous material layer 80 coplanar with the lower surface of the first seal 771. This arrangement improves the airtightness of the passenger compartment, thereby reducing noise and vibration experienced by passengers within the passenger compartment and enhancing vehicle ride comfort.

[0063] In some embodiments of the present application, as shown in Figures 1-4, the front panel 621 may be formed with a third sealing portion 622 protruding toward the battery pack 5, the second sealing member 78 may be formed with a second sealing portion 781 protruding toward the battery pack 5, and the first sealing member 77 may be formed with a first sealing portion 771 protruding toward the battery pack 5. The first sealing portion 771, the second sealing portion 781, and the third sealing portion 622 may cooperate to form an annular boss structure 72, the lower surface of which may be sealed against the battery pack 5. This arrangement further improves the sealing effect between the sealing assembly 7 and the front panel 621.

[0064] In some embodiments of the present application, the sealing assembly 7 can be located in the mounting notch 61, and along the thickness direction of the sealing assembly 7 (i.e., the Z direction shown in Figure 4), the distance between the sealing assembly 7 and the upper end of the mounting notch 61 can be smaller than the distance between the sealing assembly 7 and the lower end of the mounting notch 61.

[0065] By setting the sealing component 7 in the installation notch 61, the setting position of the sealing component 7 can be made reasonable, and by setting the sealing component 7 so that the distance between the sealing component 7 and the upper end of the installation notch 61 is smaller than the distance between the sealing component 7 and the lower end of the installation notch 61, the sealing component 7 can be located in the middle and upper part of the installation notch 61, thereby providing a larger space for the battery pack 5, which is beneficial to increasing the capacity of the battery pack 5, and thus is beneficial to increasing the cruising range of the vehicle.

[0066] In some embodiments of the present application, as shown in Figures 1 and 2, the vehicle body 6 may include a front engine compartment 62, a rear floor 63, a left sill beam 47, and a right sill beam 48. The front engine compartment 62 may be connected to the left sill beam 47 and the right sill beam 48, and the rear floor 63 may be connected to the left sill beam 47 and the right sill beam 48. In the longitudinal direction of the vehicle (i.e., the X direction shown in Figure 1), the front engine compartment 62 may be located forward of the rear floor 63. Furthermore, the left sill beam 47 and the right sill beam 48 may be located between the front engine compartment 62 and the rear floor 63. Both the left sill beam 47 and the right sill beam 48 may extend along the longitudinal direction of the vehicle. In the width direction of the vehicle (i.e., the Y direction shown in Figure 1), the left sill beam 47 and the right sill beam 48 may be spaced apart. The front engine compartment 62, the rear floor 63, the left sill beam 47, and the right sill beam 48 may collectively define a mounting notch 61. This arrangement can make the size of the installation gap 61 larger, which is beneficial to the lightweight design of the vehicle. In addition, by having the front cabin 62, the rear floor 63, the left door sill beam 47, and the right door sill beam 48 jointly define the installation gap 61, the position of the installation gap 61 can be made reasonable, so that the setting position of the battery pack 5 can be reasonable, and the space impact of the battery pack 5 on the vehicle trunk can be reduced.

[0067] In some embodiments of the present application, as shown in FIG1 , a left seal 74 can be connected to the left sill beam 47. In some optional embodiments of the present application, the left seal 74 can be located on the side of the left sill beam 47 near the right sill beam 48. The left seal 74 can have a left connecting flange, which can be welded to the left sill beam 47. A right seal 76 can be connected to the right sill beam 48. In some optional embodiments of the present application, the right seal 76 can be located on the side of the right sill beam 48 near the left sill beam 47. The right seal 76 can have a right connecting flange, which can be welded to the right sill beam 48. A front panel 621 can be connected to the front cabin 62, and a first seal 77 can be connected to the rear floor 63. This arrangement can enhance the secure connection between the seal assembly 7 and the vehicle body 6 and reduce the likelihood of separation, thereby reliably sealing the gap between the vehicle body 6 and the battery pack 5.

[0068] As some optional embodiments of the present application, the sealing assembly 7 can be connected to the vehicle body 6 by welding.

[0069] According to the vehicle of the embodiment of the present application, including the above-mentioned body assembly 100, the first seal 77 is designed to have a structure with a first sealing portion 771 and a connecting portion 772, and at least part of the connecting portion 772 is located above the second seal 78 and connected to the second seal 78. When it is necessary to match vehicle models with different wheelbases, only the first seal 77 or the second seal 78 needs to be adaptively adjusted or replaced to enable the sealing assembly 7 to match vehicle models with different wheelbases, thereby improving the versatility of the sealing assembly 7, helping to reduce the production cost of the vehicle, and ensuring the sealing performance of the sealing assembly 7.
