DETAILED DESCRIPTION

[0024] The following describes in detail embodiments of the present application, examples of which 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 intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] A vehicle body assembly 100 according to an embodiment of the present application will be described below with reference to FIG. 1 to FIG. 10 .

[0026] As shown in FIG. 1 to FIG. 10 , 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 .

[0027] 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 FIG3 ). The battery pack 5 is disposed in the vehicle body 6 and obscures 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, a portion 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.

[0028] Along the length of the vehicle body 6 (i.e., the X-direction shown in FIG1 ), the dash panel 321 is located in front of the sealing assembly 7, and the dash panel 621 is connected to the sealing assembly 7 to form an annular structure. 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, 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.

[0029] 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.

[0030] 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 a large amount 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 using the sealing assembly 7 and the dash panel 621 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.

[0031] 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.

[0032] Therefore, by configuring the battery pack 5 to constitute at least part of the floor of the body assembly 100, part of the floor of the traditional body can be eliminated, which is beneficial to the lightweight design of the vehicle and helps to improve the vehicle's cruising range. In addition, through the sealing assembly 7 and the front panel 621, the gap between the body body 6 and the battery pack 5 can be sealed, which can improve the airtightness of the passenger compartment, thereby helping to improve the ride comfort of the vehicle.

[0033] As some optional embodiments of the present application, the battery pack 5 can serve as the front floor of the vehicle body assembly 100 .

[0034] In some embodiments of the present application, as shown in Figures 1 and 2, the sealing assembly 7 may be formed with a relief hole 71. That is, the sealing assembly 7 may have a hollow structure, and the relief hole 71 of the sealing assembly 7 may be arranged corresponding to the mounting notch 61. The battery pack 5 may block the relief hole 71, and the battery pack 5 may also block the mounting notch 61 of the vehicle body 6. By forming the relief hole 71 in the sealing assembly 7, the weight of the sealing assembly 7 can be reduced, thereby facilitating a lightweight design of the vehicle. The relief hole 71 can also avoid the upper surface of the battery pack 5, ensuring that the battery pack 5 can be configured as at least a portion of the floor of the vehicle body assembly 100.

[0035] In some embodiments of the present application, as shown in Figures 3 and 4, the battery pack 5 can be disposed below the sealing assembly 7 along the height direction of the vehicle body 6 (i.e., the Z direction shown in Figure 3), and the battery pack 5 can be sealed with the lower surface of the sealing assembly 7. 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 sealing assembly 7. 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.

[0036] In some embodiments of the present application, as shown in Figures 1, 2, 9 and 10, the sealing assembly 7 and the front panel 621 can both be formed with a sealing boss 721 protruding toward the battery pack 5. The sealing boss 721 can protrude downward (i.e., toward the battery pack 5) along the height direction of the vehicle body 6 (i.e., the Z direction shown in Figure 3). The sealing boss 721 of the sealing assembly 7 and the sealing boss 721 of the front panel can cooperate to form an annular boss structure 72.

[0037] The lower surface of the sealing boss 721 can seal against the battery pack 5. In some optional embodiments of the present application, the lower surface of the sealing boss 721 can also seal against the upper surface of the battery pack 5. By forming the sealing boss 721 protruding toward the battery pack 5 on both the sealing assembly 7 and the front panel 621, the sealing effect between the sealing assembly 7 and the front panel 621 can be further improved.

[0038] In some embodiments of the present application, as shown in Figures 1, 2, and 5 to 10, the sealing assembly 7 may include a left seal 74, a rear seal 75, and a right seal 76. The left seal 74 and the right seal 76 may be arranged opposite and spaced apart along the width direction of the vehicle body 6 (i.e., the Y direction shown in Figure 1), and the front panel 621, the left seal 74, the rear seal 75, and the right seal 76 may be connected in sequence end to end.

[0039] 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 rear seal 75, the other end of the rear seal 75 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 rear seal 75, 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 rear seal 75, and the right seal 76 may all be connected to the vehicle body 6.

[0040] The left seal 74, the rear seal 75 and the right seal 76 can all form parts of the boss structure 72. Specifically, as shown in Figures 5 to 8, the front panel 621, the left seal 74, the rear seal 75 and the right seal 76 can all have a sealing boss 721 protruding toward the battery pack 5. The sealing boss 721 of any one of the front panel 621, the left seal 74, the rear seal 75 and the right seal 76 can all be parts of the boss structure 72. The sealing bosses 721 of the front panel 621, the left seal 74, the rear seal 75 and the right seal 76 can together constitute the boss structure 72.

[0041] Such an arrangement can make the structural form of the sealing assembly 7 and the front panel 621 reasonable, and by connecting at least one of the left seal 74, the rear seal 75, and the right seal 76 to the vehicle body 6, the connection between the sealing assembly 7 and the vehicle body 6 can be firm. By forming a portion of the boss structure 72 on the front panel 621, the left seal 74, the rear seal 75, and the right seal 76, it is beneficial to further improve the sealing effect of the sealing assembly 7 and the front panel 621.

[0042] As some optional embodiments of the present application, the left seal 74, the rear seal 75 and the right seal 76 can be an integrally formed part. As some optional embodiments of the present application, the left seal 74, the rear seal 75 and the right seal 76 can be separate parts.

[0043] In some embodiments of the present application, as shown in Figures 3 and 4 , the battery pack 5 may be formed with a sealing surface 54, and the lower surface of the sealing boss 721 may mate with the sealing surface 54. In some optional embodiments of the present application, the dash panel 621, left seal 74, rear seal 75, and right seal 76 may each have a sealing boss 721 protruding toward the battery pack 5. The lower surfaces of the sealing bosses 721 of the dash panel 621, left seal 74, rear seal 75, and right seal 76 may lie in the same plane. Furthermore, the upper surface of the battery pack 5 may be configured as the sealing surface 54, which may mate with the lower surface of the sealing boss 721. For example, the sealing surface 54 may be parallel to the lower surface of the sealing boss 721. This arrangement improves the sealing between the sealing boss 721 and the battery pack 5, enabling the sealing assembly 7 and dash panel 621 to reliably seal the gap between the vehicle body 6 and the battery pack 5, thereby enhancing the airtightness of the passenger compartment.

[0044] In some embodiments of the present application, as shown in Figures 3 and 4 , the vehicle body assembly 100 may further include a flexible seal 55, which may be interposed between the battery pack 5 and the sealing assembly 7. Specifically, the flexible seal 55 may be interposed between the sealing boss 721 and 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.

[0045] As some optional embodiments of the present application, the sealing assembly 7 and the front panel 621 may each be formed with a sealing boss 721 protruding toward the battery pack 5. The lower surface of the sealing boss 721 may be sealed against the upper surface of the battery pack 5, and a flexible seal 55 may be sandwiched between the upper surface of the battery pack 5 and the lower surface of the sealing boss 721. By providing the flexible seal 55, the airtightness of the passenger compartment can be further improved, thereby further enhancing the ride comfort of the vehicle.

[0046] In some embodiments of the present application, as shown in Figures 3 and 4, the sealing assembly 7 can be located in the mounting notch 61, and along the height direction of the vehicle body 6 (i.e., the Z direction shown in Figure 3), 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.

[0047] 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.

[0048] 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.

[0049] In some embodiments of the present application, as shown in Figures 1 and 2, 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 disposed on a side of the left sill beam 47 near the right sill beam 48. The left seal 74 can have a left connecting flange 742 (as shown in Figure 6), 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 disposed on a side of the right sill beam 48 near the left sill beam 47. The right seal 76 can have a right connecting flange 761 (as shown in Figure 7), which can be welded to the right sill beam 48. The front panel 621 can be connected to the front cabin 62, and the rear seal 75 can be connected to the rear floor 63. Such an arrangement can improve the connection firmness between the sealing assembly 7 and the vehicle body 6 and reduce the probability of separation of the sealing assembly 7 from the vehicle body 6, thereby reliably sealing the gap between the vehicle body 6 and the battery pack 5.

[0050] As some optional embodiments of the present application, the sealing assembly 7 can be connected to the vehicle body 6 by welding.

[0051] In some embodiments of the present application, as shown in Figures 3 and 4 , the battery pack 5 may have multiple battery pack connection portions 53, each of which may be connected to the corresponding left and right sill beams 47 and 48. Specifically, the battery pack 5 may have two battery pack connection portions 53, located on the left and right sides of the battery pack 5 along the width direction of the vehicle (i.e., the Y direction shown in Figure 3). That is, one of the two battery pack connection portions 53 is located near the left sill beam 47, and the other battery pack connection portion 53 is located near the right sill beam 48. The battery pack connection portion 53 located near the right sill beam 48 can be connected to the right sill beam 48, and the battery pack connection portion 53 located near the left sill beam 47 can be connected to the left sill beam 47.

[0052] In some optional embodiments of the present application, as shown in Figures 3 and 4, the battery pack connection portion 53 can be located below the sill beam 4 and connected to the sill beam 4 via bolts. In some optional embodiments of the present application, the battery pack connection portion 53 can be connected to the sill inner plate 43 of the sill beam 4 via bolts. This arrangement can connect the battery pack 5 to the sill beam 4, thereby improving the installation security of the battery pack 5.

[0053] As some optional embodiments of the present application, the left and right sides of the battery pack 5 can be connected to the rocker beam 4, the front side of the battery pack 5 can be connected to the bottom of the front wall of the vehicle, and the rear side of the battery pack 5 can be connected to the rear floor 63 of the vehicle. As some optional embodiments of the present application, the battery pack 5 and the vehicle body 6 can be connected by bolts.

[0054] In some embodiments of the present application, as shown in Figures 1 to 4, the vehicle body assembly 100 may further include: a seat mounting crossbeam 199. The seat mounting crossbeam 199 may be disposed above the sealing assembly 7 along the height direction of the vehicle body 6 (i.e., the Z direction as shown in Figure 3), and the seat mounting crossbeam 199 may be welded to the sealing assembly 7. In some optional embodiments of the present application, the seat mounting crossbeam 199 may extend along the width direction of the vehicle body 6 (i.e., the Y direction as shown in Figure 3), and the ends of the seat mounting crossbeam 199 may be welded to the left seal 74 and the right seal 76, respectively.

[0055] The battery pack 5 can be connected to the seat-mounted crossbeam 199. It is understood that the seat-mounted crossbeam 199 can be positioned above the battery pack 5 along the height direction of the vehicle body 6 (i.e., the Z direction as shown in FIG3 ). The battery pack 5 and the seat-mounted crossbeam 199 can be connected by bolts. In some optional embodiments of the present application, the battery pack 5 and the seat-mounted crossbeam 199 can be connected by multiple bolts, and the multiple bolts can be arranged at intervals along the width direction of the vehicle body 6 (i.e., the Y direction as shown in FIG3 ). By connecting the battery pack 5 to the seat-mounted crossbeam 199, the installation security of the battery pack 5 can be improved, and the battery pack 5 can be prevented from separating from the vehicle. Furthermore, in the event of a side collision, the seat-mounted crossbeam 199 and the battery pack 5 can form at least two transmission paths, which can transfer the side collision load to the non-collision area, thereby improving the vehicle's impact energy resistance and increasing the torsional rigidity of the vehicle body.

[0056] As some optional embodiments of the present application, the seat mounting cross beam 199 may include a front seat mounting rear cross beam 2 , and the battery pack 5 may be connected to the front seat mounting rear cross beam 2 .

[0057] As some optional embodiments of the present application, along the length direction of the vehicle (ie, the X direction shown in FIG. 1 ), the seat mounting cross beam 199 is located between the front cabin 62 and the rear floor 63 .

[0058] In some embodiments of the present application, as shown in Figures 1 and 2, the sealing assembly 7 may have a connecting arm 741 protruding toward the inside of the sealing assembly 7, and the connecting arm 741 may be connected to the seat mounting cross beam 199. Specifically, the connecting arm 741 may be welded to the seat mounting cross beam 199. As some optional embodiments of the present application, the connecting arm 741 may be welded to the bottom of the seat mounting cross beam 199. It should be noted that when the vehicle is involved in a side collision, the connection between the seat mounting cross beam 199 and the sealing assembly 7 is the main stress point. By providing the sealing assembly 7 with a connecting arm 741 protruding toward the inside of the sealing assembly 7 and connecting the connecting arm 741 to the seat mounting cross beam 199, the connection strength at the connection between the seat mounting cross beam 199 and the sealing assembly 7 can be improved, thereby improving the vehicle's impact resistance and improving the safety of the vehicle.

[0059] In some embodiments of the present application, as shown in FIG. 1 and FIG. 2 , the sealing assembly 7 may include a left seal 74 , a rear seal 75 , and a right seal 76 , and both the left seal 74 and the right seal 76 may be connected to the rear seal 75 .

[0060] 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 rear seal 75, the other end of the rear seal 75 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. The left seal 74 may have a connecting arm 741 that extends toward the right seal 76 along the width of the vehicle (i.e., the Y direction as shown in FIG1 ). Alternatively, the right seal 76 may have a connecting arm 741 that extends toward the left seal 74 along the width of the vehicle (i.e., the Y direction as shown in FIG1 ). Alternatively, both the left and right seals 74 and 76 may have connecting arms 741 that extend toward each other. It can be understood that the seat mounting beam 199 can be connected to the left seal 74 and the right seal 76. By making the left seal 74 and the right seal 76 both have a connecting arm 741, and connecting the connecting arm 741 to the seat mounting beam 199, the connection strength between the seat mounting beam 199 and the left seal 74 and the right seal 76 can be improved, and the risk of cracking at the connection between the seat mounting beam 199 and the left seal 74 and the right seal 76 can be reduced, thereby improving the safety of the vehicle.

[0061] In some embodiments of the present application, as shown in FIG1 , the length of the connecting arm 741 may be J1, and J1 may satisfy the relationship: 60 mm ≤ J1 ≤ 100 mm. That is, the length of the connecting arm 741 may be any value between 60 mm and 100 mm. For example, the length of the connecting arm 741 may be, but is not limited to, 60 mm, 80 mm, 100 mm, etc. It should be explained that the length of the connecting arm 741 is the length of the connecting arm 741 along the width direction of the vehicle (i.e., the Y direction shown in FIG1 ). This arrangement can make the length of the connecting arm 741 reasonable, can reliably improve the connection strength between the left seal 74 and / or the right seal 76 and the seat mounting crossbeam 199, and can reduce the risk of cracking at the connection between the seat mounting crossbeam 199 and the left seal 74 and the right seal 76.

[0062] According to the vehicle of the embodiment of the present application, including the above-mentioned body assembly 100, by configuring the battery pack 5 to constitute at least part of the floor of the body assembly 100, part of the floor of the traditional body can be omitted, which is beneficial to the lightweight design of the vehicle and is beneficial to improving the vehicle's cruising range. In addition, through the sealing assembly 7 and the front panel 621, the gap between the body body 6 and the battery pack 5 can be sealed, which can improve the airtightness of the passenger compartment, thereby helping to improve the ride comfort of the vehicle.
