[0031] Along the length direction of the vehicle body component 100 (ie Figure 2The first air chamber plate 10 is located in front of the second air chamber plate 20; the first air chamber plate 10 includes a first connecting portion 11, the second air chamber plate 20 includes a second connecting portion 21, and the front panel 30 includes a third connecting portion 31. The first connecting portion 11, the second connecting portion 21, and the third connecting portion 31 are connected along the length direction of the vehicle body component 100 (i.e. Figure 2 The third connection portion 31 is located between the first connection portion 11 and the second connection portion 21 or on a side of the second connection portion 21 away from the first connection portion 11.

[0032] Among them, along the length direction of the body component 100 (i.e. Figure 2 The first air chamber plate 10 is located in front of the second air chamber plate 20, the first air chamber plate 10 includes a first connecting portion 11, the second air chamber plate 20 includes a second connecting portion 21, and the front panel 30 includes a third connecting portion 31. The first connecting portion 11, the second connecting portion 21, and the third connecting portion 31 are connected along the length direction of the vehicle body component 100 (i.e. Figure 2 The first connection portion 11, the second connection portion 21, and the third connection portion 31 are arranged in connection. As some embodiments of the present invention, the first connection portion 11, the second connection portion 21, and the third connection portion 31 are connected by three-layer spot welding.

[0033] The third connection portion 31 is located between the first connection portion 11 and the second connection portion 21 or on a side of the second connection portion 21 away from the first connection portion 11. That is, the third connection portion 31 can be located between the first connection portion 11 and the second connection portion 21, or the third connection portion 31 can be located on a side of the second connection portion 21 away from the first connection portion 11, that is, along the length direction of the vehicle body component 100 (i.e. Figure 2 The third connection portion 31 may be located at the rear side of the second connection portion 21 (in the X direction shown).

[0034] As some embodiments of the present application, the dash panel 30 may be located between the first air chamber panel 10 and the second air chamber panel 20 , or the dash panel 30 may be located on a side of the second air chamber panel 20 away from the first air chamber panel 10 .

[0035] In the embodiment where the third connection part 31 is located between the first connection part 11 and the second connection part 21, glue may be applied between the third connection part 31 and the first connection part 11 and / or between the third connection part 31 and the second connection part 21; in the embodiment where the third connection part 31 is located on the side of the second connection part 21 away from the first connection part 11, glue may be applied between the second connection part 21 and the third connection part 31 and / or between the second connection part 21 and the first connection part 11.

[0036] It should be noted that the first connecting portion 11, the second connecting portion 21 and the third connecting portion 31 are connected along the length direction (ie Figure 2 The arrangement of the first connecting part, the second connecting part and the third connecting part can be made to be in the length direction of the body component (i.e., the X direction). Figure 2 The X direction shown in the figure) can increase the adhesion of the colloid, reduce the difficulty of gluing, and make it easy to check whether the gluing is reliable, which is beneficial to improving production efficiency, and further can reduce the probability of water entering the passenger compartment due to poor sealing of the passenger compartment, which is beneficial to improving the sealing of the body component 100 and the reliability of the body component 100.

[0037] Thus, by making the first connection portion 11, the second connection portion 21 and the third connection portion 31 along the length direction (ie, Figure 2 The first connecting portion 11, the second connecting portion 21, and the third connecting portion 31 are arranged and connected in the X direction as shown, which can reduce the intrusion of the second air chamber plate 20 into the passenger compartment, which is beneficial to increase the passenger compartment space. In addition, the gluing direction of the connection between the first connecting portion 11, the second connecting portion 21, and the third connecting portion 31 can be the length direction of the body component 100 (i.e. Figure 2 The X direction shown in the figure is helpful to reduce the difficulty of gluing, improve the adhesion of the colloid, and reduce the difficulty of gluing inspection, reduce the probability of poor sealing, and improve the sealing performance.

[0038] In some embodiments of the present invention, Figure 3 As shown, along the length direction of the body component 100 (ie Figure 2 The spacing distance between the end of the second air chamber plate 20 away from the first air chamber plate 10 and the front panel 30 is A, which satisfies the relationship: 28 mm ≤ A ≤ 38 mm.

[0039] Among them, the spacing distance between the end of the second air chamber plate 20 away from the first air chamber plate 10 and the front panel 30 is A, and A can satisfy the relationship: 28mm≤A≤38mm, that is, the spacing distance A between the end of the second air chamber plate 20 away from the first air chamber plate 10 and the front panel 30 can be any value between 28mm and 38mm. For example, the spacing distance A between the end of the second air chamber plate 20 away from the first air chamber plate 10 and the front panel 30 can be but not limited to 28mm, 33mm, 38mm, etc. As some embodiments of the present application, the spacing distance A between the end of the second air chamber plate 20 away from the first air chamber plate 10 and the front panel 30 can be 33mm.

[0040] As some embodiments of the present application, along the length direction of the vehicle body component 100 (i.e. Figure 2The maximum spacing distance between the end of the second air chamber plate 20 away from the first air chamber plate 10 and the front panel 30 is A.

[0041] By making the spacing distance A between the end of the second air chamber plate 20 away from the first air chamber plate 10 and the front panel 30 any value between 28 mm and 38 mm, the design of the body component 100 can be reasonable, the intrusion amount of the second air chamber plate 20 into the passenger compartment can be effectively reduced, and the layout space in the vehicle can be increased. In addition, such a setting can also reduce the size and weight of the second air chamber plate 20, which is beneficial to the lightweight design of the body component 100 and helps save development costs.

[0042] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the vehicle body assembly 100 further includes: a windshield lower cross beam 40 , which is connected to the first air chamber plate 10 and the second air chamber plate 20 and together defines a chamber 60 .

[0043] The vehicle body assembly 100 further includes a windshield lower cross beam 40, which is connected to the first air chamber plate 10 and the second air chamber plate 20. The windshield lower cross beam 40 and the first air chamber plate 10 and the second air chamber plate 20 are connected by welding, clamping, etc., but not limited to. In some embodiments of the present application, the windshield lower cross beam 40 and the first air chamber plate 10 and the second air chamber plate 20 are connected by welding. The windshield lower cross beam 40 and the first air chamber plate 10 and the second air chamber plate 20 jointly define a chamber 60.

[0044] By connecting the lower cross beam 40 of the windshield with the first air chamber plate 10 and the second air chamber plate 20 and jointly defining the chamber 60, the structure of the body assembly 100 can be made reasonable. When the vehicle collides from the front, the chamber 60 can collapse and absorb energy to reduce the intrusion of the body assembly 100 into the passenger compartment, which is beneficial to improving the safety performance of the vehicle.

[0045] In some embodiments of the present invention, Figure 2 As shown, there is a drain hole 70 between the first connection part 11 and the second connection part 21 or between the first connection part 11 and the third connection part 31 , and the drain hole 70 is connected to the chamber 60 .

[0046] Among them, there is a drain hole 70 between the first connection part 11 and the second connection part 21 or between the first connection part 11 and the third connection part 31, that is, there is a drain hole 70 between the first connection part 11 and the second connection part 21, or there is a drain hole 70 between the first connection part 11 and the third connection part 31, and the drain hole 70 is connected to the chamber 60.

[0047] Specifically, in the embodiment where the third connection portion 31 is located between the first connection portion 11 and the second connection portion 21 , a drain hole 70 is provided between the first connection portion 11 and the third connection portion 31 .

[0048] In the embodiment where the third connection portion 31 is located on a side of the second connection portion 21 away from the first connection portion 11 , a drain hole 70 is defined between the first connection portion 11 and the second connection portion 21 .

[0049] By providing a drain hole 70 between the first connection part 11 and the second connection part 21 or between the first connection part 11 and the third connection part 31, and connecting the drain hole 70 with the chamber 60, the liquid in the chamber 60 can be discharged from the chamber 60 through the drain hole 70, thereby reducing the amount of liquid accumulated in the chamber 60, thereby reducing the probability of rusting of the body component 100, and helping to increase the service life of the body component 100.

[0051] Among them, the first air chamber plate 10 also includes a first chamber plate body 12, and the first chamber plate body 12 is connected to the first connecting part 11. As some embodiments of the present application, the first chamber plate body 12 and the first connecting part 11 are constructed as an integrally formed part, and the integrally formed part has good structural strength. By integrally forming the first chamber plate body 12 and the first connecting part 11, the connection reliability between the first chamber plate body 12 and the first connecting part 11 can be improved, and the probability of breakage at the connection between the first chamber plate body 12 and the first connecting part 11 can be reduced.

[0052] Furthermore, along the length direction of the vehicle body component 100 (i.e. Figure 2 The first chamber plate body 12 is gradually tilted downward from one end of the first chamber plate body 12 away from the first connection portion 11 to one end close to the first connection portion 11 to guide the liquid to the drain hole 70.

[0053] Such a configuration enables the liquid entering the chamber 60 to flow along the first chamber plate body 12 to the drain hole 70 under the action of gravity and the guiding action of the first chamber plate body 12, and then be discharged through the drain hole 70, thereby effectively reducing the probability of liquid accumulation in the chamber 60, and can effectively reduce the probability of rust of the body component 100, which is beneficial to increasing the service life of the body component 100.

The fifth connection part 43 is connected to the second air chamber plate 20, and the connection method of the fifth connection part 43 and the second air chamber plate 20 can be, but not limited to, welding, clamping, etc. As some embodiments of the present application, the fifth connection part 43 is connected to the second air chamber plate 20 by welding.

In other words, the lower beam body 41 is constructed as a multi-section bent structure.

[0064] By making the lower beam body 41 tilt gradually from one end close to the fifth connecting portion 43 to the end far away from the fifth connecting portion 43, at least a portion of the lower beam body 41 is gradually tilted downward, so that the structural design of the lower beam body 41 can be reasonable, which is beneficial to the forming of the lower beam body 41 by the stamping process, and can also reduce the structural size of the lower beam body 41, reduce the weight of the lower beam body 41, and reduce the development cost.
