[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] The following is for reference. Figures 1-6 The description includes a central crossbeam 8 of a vehicle according to an embodiment of the present invention, wherein the central crossbeam 8 is configured as part of the lower front crossbeam assembly 98 of the vehicle.

[0037] like Figure 3 and Figure 5 As shown, the crossbeam 8 of the vehicle according to an embodiment of the present invention includes: a crossbeam body 81 and two bosses 82, the crossbeam body 81 being along a first direction ( Figure 1 , 2 Extending along the Y direction (as shown in 3, 5, and 6); along the second direction (i.e. Figure 3 , 4 The boss 82 and the crossbeam body 81 are arranged along the first direction (i.e., the Z direction shown). Figure 1 , 2 (As shown in Y direction in 3, 5, and 6), two protrusions 82 are respectively located at both ends of the crossbeam body 81. The crossbeam body 81 and the protrusions 82 together define the clearance space 83, in the first direction (i.e., Figure 1 , 2 The Y direction shown in 3, 5, and 6) and the second direction (i.e. Figure 3 , 4 The Z direction shown is perpendicular to the direction indicated.

[0038] Among them, along the second direction (i.e. Figure 3 , 4 (As shown in the Z direction), the boss 82 and the crossbeam body 81 are arranged together. Specifically, the two bosses 82 are located on the same side of the crossbeam body 81. The bosses 82 are connected to the crossbeam body 81. As some embodiments of this application, the connection between the bosses 82 and the crossbeam body 81 can be, but is not limited to, a welding connection, or the bosses 82 and the crossbeam body 81 can be integrally formed.

[0039] Along the first direction (i.e.) Figure 1 , 2(As shown in the Y direction of 3, 5, and 6), two protrusions 82 are arranged alternately, and the two protrusions 82 are located at both ends of the crossbeam body 81. The crossbeam body 81 and the two protrusions 82 together define a clearance space 83, which can accommodate other components of the vehicle. For example, the clearance space 83 can accommodate part of the high-voltage wiring harness between the front engine compartment and the power battery, or the clearance space 83 can accommodate part of the braking system piping.

[0040] It should be noted that the middle crossbeam 8 of the vehicle in this application can be part of the lower crossbeam assembly of the front bulkhead of the vehicle, for example, as Figure 1 and Figure 2 As shown, the front lower crossbeam assembly 98 may include a middle crossbeam 8 and side crossbeams 9. There may be two side crossbeams 9. The middle crossbeam 8 may be connected between the two side crossbeams 9. The ends of the two side crossbeams 9 away from the middle crossbeam 8 may be connected to the two A-pillars of the vehicle respectively. Furthermore, the front lower crossbeam assembly 98 may be connected to the vehicle's tower pack 6.

[0041] The frontal collision force borne by the tower 6 can be transferred to the central crossbeam 8 and the side crossbeams 9. By providing the boss 82, the connection area between the central crossbeam 8 and the side crossbeams 9 can be increased, facilitating their connection. The boss 82 also acts as a diagonal support, allowing for a tighter connection between the central crossbeam 8 and the side crossbeams 9 under gravity. Furthermore, it helps the central crossbeam 8 disperse collision energy to both sides, reducing the risk of stress concentration and minimizing direct impact on the passenger compartment. Moreover, the side crossbeams 9 can distribute the collision energy along the first direction (i.e.,...) Figure 1 , 2 The energy is transferred to the A-pillar in the Y direction (as shown in 3, 5, and 6). This arrangement enhances the rigidity of the entire vehicle structure, reduces deformation of the body structure under collision or dynamic load, and improves the stability and safety of the vehicle. Furthermore, it can effectively disperse and absorb collision energy, reducing the direct impact on the passenger compartment and thus protecting the safety of the occupants. In addition, during vehicle operation, especially at high speeds or during sharp turns, it can enhance the lateral stability of the vehicle, reduce body roll and sway, and improve driving control and comfort.

[0042] As some embodiments of this application, the boss 82 and the corresponding side beam 9 can be connected by means of, but not limited to, bolts, riveting, connecting plates, etc. As some embodiments of this application, the beam body 81 and the side beam 9 can be connected by means of, but not limited to, bolts, riveting, connecting plates, etc.

[0043] As some embodiments of this application, the first direction (i.e. Figure 1 , 2 The Y-direction shown in 3, 5, and 6 can be the Y-direction of the vehicle, and the second direction (i.e., Figure 3 ,4 The Z direction shown can be the Z direction of the vehicle.

[0044] As some embodiments of this application, both the middle crossbeam 8 and the side crossbeam 9 can be made of aluminum. For example, the middle crossbeam 8 can be made of extruded aluminum, and the side crossbeam 9 can be made of die-cast aluminum.

[0045] Therefore, by setting the boss 82, the connection area between the middle crossbeam 8 and other components can be increased, making it easier to connect the middle crossbeam 8 with other components and making the connection between the middle crossbeam 8 and other components tighter. This is beneficial for the middle crossbeam 8 to disperse collision energy to both sides, reduce the risk of stress concentration, and improve the safety performance of the vehicle. In addition, by having the crossbeam body 81 and the boss 82 jointly define the clearance space 83, other components of the vehicle can be accommodated through the clearance space 83, reducing the difficulty of arranging vehicle parts.

[0046] In some embodiments of this utility model, such as Figure 4 As shown, the beam body 81 includes: a beam top plate 812, the beam top plate 812 including a first sub-top plate 8121 and a second sub-top plate 8122, along a third direction (i.e. Figure 4 , 5 (as shown in the X direction of 6), the first sub-top plate 8121 and the second sub-top plate 8122 are arranged and connected. From the end of the first sub-top plate 8121 near the second sub-top plate 8122 to the end away from the second sub-top plate 8122, the first sub-top plate 8121 and the boss 82 are along the second direction (i.e., Figure 3 , 4 The spacing in the Z direction (as shown) gradually increases, while the spacing in the third direction (i.e.) Figure 4 , 5 The X direction shown in Figure 6) and the first direction (i.e. Figure 1 , 2 , the Y direction shown in 3, 5 and 6), the second direction (i.e. Figure 3 , 4 The Z-direction shown is perpendicular to all directions.

[0047] Among them, along the third direction (i.e. Figure 4 , 5 As shown in the X direction (as indicated by 6), the first sub-top plate 8121 and the second sub-top plate 8122 are arranged and connected. As some embodiments of this application, the first sub-top plate 8121 and the second sub-top plate 8122 can be fixedly connected. For example, the connection method between the first sub-top plate 8121 and the second sub-top plate 8122 can be, but is not limited to, welding, riveting, etc., or the first sub-top plate 8121 and the second sub-top plate 8122 can be integrally formed. As some embodiments of this application, the third-party direction (i.e....) Figure 4 , 5 The X direction shown in Figure 6 can be the X direction of the vehicle.

[0048] From the end of the first sub-top plate 8121 near the second sub-top plate 8122 to the end away from the second sub-top plate 8122, the first sub-top plate 8121 and the boss 82 are along the second direction (i.e. Figure 3 , 4 The spacing in the Z direction (as shown) gradually increases. As some embodiments of this application, the first sub-top plate 8121 can be constructed as an arc-shaped plate; as some embodiments of this application, the first sub-top plate 8121 can be constructed as a flat plate. Furthermore, along the X direction of the vehicle (i.e., Figure 4 , 5 (As shown in the X direction of 6), the first sub-top plate 8121 is located in front of the second sub-top plate 8122.

[0049] This arrangement makes the structure of the top plate 812 of the crossbeam reasonable. The first sub-top plate 8121 can smoothly transfer part of the force transmitted by the middle crossbeam 8 to the second sub-top plate 8122, reducing the risk of stress concentration and improving the reliability of the middle crossbeam 8.

[0050] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the vehicle's central crossbeam 8 also includes: an overlap plate 84, along a third direction (i.e., Figure 4 , 5 (As shown in the X direction of 6), the overlapping plate 84 is connected to the end of the first sub-top plate 8121 away from the second sub-top plate 8122. The overlapping plate 84 is adapted to be connected to the front bulkhead of the vehicle, and the second sub-top plate 8122 is adapted to be connected to the front floor of the vehicle.

[0051] Among them, along the third direction (i.e. Figure 4 , 5 (As shown in the X direction of 6), the overlapping plate 84 is connected to the end of the first sub-top plate 8121 away from the second sub-top plate 8122. As some embodiments of this application, the connection method between the overlapping plate 84 and the first sub-top plate 8121 can be welding or riveting, or the overlapping plate 84 and the first sub-top plate 8121 can be integrally formed.

[0052] The overlapping plate 84 is adapted to connect with the front bulkhead of the vehicle, and the second sub-roof plate 8122 is adapted to connect with the front floor of the vehicle. As some embodiments of this application, the overlapping plate 84 can be located below the front bulkhead and connected to it. The connection method between the overlapping plate 84 and the front bulkhead can be, but is not limited to, bolt connection, riveting, etc. As some embodiments of this application, the second sub-roof plate 8122 can be located below the front floor. As some embodiments of this application, the second sub-roof plate 8122 can be located above the front floor. The connection method between the second sub-roof plate 8122 and the front floor can be, but is not limited to, bolt connection, riveting, etc. Furthermore, the upper surface of the second sub-roof plate 8122 can serve as a foot surface for occupants.

[0053] This configuration allows the middle crossbeam 8 to be connected to the front bulkhead and front floor, integrating the front bulkhead and front floor into the overall vehicle structure, thus improving the vehicle's torsional resistance. Furthermore, the first sub-roof plate 8121 can smoothly transfer some of the force transmitted by the middle crossbeam 8 to the second sub-roof plate 8122 and front floor, reducing the risk of stress concentration.

[0054] In some embodiments of this utility model, such as Figure 4 As shown, the upper surface of the second sub-top plate 8122 is planar, and / or the upper surface of the overlapping plate 84 is planar.

[0055] The upper surface of the second sub-top plate 8122 is planar, or the upper surface of the overlapping plate 84 is planar, or the upper surface of the second sub-top plate 8122 is planar, and the upper surface of the overlapping plate 84 is planar.

[0056] The upper surface of the second sub-roof plate 8122 is flat. As some embodiments of this application, the second sub-roof plate 8122 can be located below the front floor of the vehicle. The upper surface of the second sub-roof plate 8122 is fitted and connected to the front floor. The connection between the second sub-roof plate 8122 and the front floor can be, but is not limited to, bolt connection, riveting, etc. In addition, the upper surface of the second sub-roof plate 8122 can serve as a foot surface for occupants.

[0057] By constructing the upper surface of the second sub-top plate 8122 as a plane, the contact area between the second sub-top plate 8122 and the front floor can be increased, which facilitates connection and improves connection strength.

[0058] The upper surface of the lap plate 84 is flat. As some embodiments of this application, the lap plate 84 can be located below the front bulkhead of the vehicle. The upper surface of the lap plate 84 mates with and connects to the front bulkhead. The connection method between the lap plate 84 and the front bulkhead can be, but is not limited to, bolt connection, riveting, etc.

[0059] By constructing the upper surface of the overlap plate 84 as a plane, the contact area between the overlap plate 84 and the front bulkhead can be increased, making the connection easier and improving the connection strength.

[0060] In some embodiments of this utility model, such as Figure 4 As shown, the vehicle's middle crossbeam 8 also includes: a first partition plate 85, a crossbeam body 81 defining a first cavity 811 and also including: a crossbeam bottom plate 813, and a crossbeam top plate 812 and a crossbeam bottom plate 813 along a second direction (i.e. Figure 3 , 4 The first partition plate 85 is connected between the top plate 812 and the bottom plate 813 of the crossbeam to divide the first cavity 811 into two first sub-cavities 8111, along the second direction (i.e., the Z-direction shown). Figure 3 ,4 (as shown in the Z direction), one of the first sub-cavities 8111 is directly opposite the boss 82 and has a larger cross-sectional area than the other first sub-cavity 8111.

[0061] In some embodiments of this application, the first cavity 811 is along a first direction (i.e. Figure 1 , 2 The Y-direction (as shown in 3, 5, and 6) penetrates through the crossbeam body 81, meaning the crossbeam body 81 is constructed as a hollow structure.

[0062] The top plate 812 and the bottom plate 813 of the crossbeam are along the second direction (i.e. Figure 3 , 4 The interval shown is in the Z direction, that is, along the second direction (i.e. Figure 3 , 4 As shown in the Z direction), the top plate 812 and the bottom plate 813 of the crossbeam have a certain distance. As some embodiments of this application, along the second direction (i.e. Figure 3 , 4 (As shown in the Z direction), the top plate 812 of the crossbeam can be located at the upper end of the bottom plate 813 of the crossbeam.

[0063] A first partition plate 85 connects the top plate 812 and the bottom plate 813 of the crossbeam, dividing the first cavity 811 into two first sub-cavities 8111. As some embodiments of this application, along the second direction (i.e....) Figure 3 , 4 (As shown in the Z direction), the first partition plate 85 is located between the top plate 812 and the bottom plate 813 of the crossbeam, and one end of the first partition plate 85 is connected to the top plate 812 of the crossbeam, and the other end of the first partition plate 85 is connected to the bottom plate 813 of the crossbeam. As some embodiments of this application, the connection between the first partition plate 85 and the top plate 812 and the bottom plate 813 of the crossbeam can be welded, or the first partition plate 85 and the top plate 812 and the bottom plate 813 of the crossbeam can be integrally formed.

[0064] As some embodiments of this application, along the second direction (i.e. Figure 3 , 4 (As shown in the Z direction), the first partition plate 85 can be arranged perpendicular to the bottom plate 813 of the crossbeam, that is, the first partition plate 85 is arranged perpendicular to the X direction of the vehicle.

[0065] Along the second direction (i.e.) Figure 3 , 4 As shown in the Z direction), one of the first sub-cavities 8111 is directly opposite the boss 82 and has a larger cross-sectional area than the other first sub-cavity 8111. As some embodiments of this application, along the X direction of the vehicle (i.e. Figure 4 , 5The two first sub-cavities 8111 are arranged in the X direction (as shown in Figure 6), with the first sub-cavity 8111 located in front along the second direction (i.e., Figure 3 , 4 The cross-sectional area of ​​the first sub-cavity 8111 (in the Z direction shown) is opposite to the boss 82 and located in front of it is greater than the cross-sectional area of ​​the other first sub-cavity 8111.

[0066] By aligning one of the first sub-cavities 8111 directly with the boss 82, the bending and compressive strength of the middle crossbeam 8 can be improved. This makes the middle crossbeam 8 of this application more stable and reliable when the vehicle is subjected to a collision or large dynamic loads, improving the vehicle's safety performance and helping to extend the service life of the middle crossbeam 8. Furthermore, by making the cross-sectional area of ​​the front first sub-cavity 8111 larger than that of the rear first sub-cavity 8111, it is beneficial to direct the collision energy from the first sub-cavity 8111 with the larger cross-sectional area along the first direction (i.e., Figure 1 , 2 The impact is dispersed in the Y direction (as shown in 3, 5, and 6), thereby reducing the direct impact on the passenger compartment and further improving the vehicle's safety performance.

[0067] In some embodiments of this utility model, such as Figure 4 As shown, one end of the first partition plate 85 connected to the top plate of the crossbeam 812 is connected between the end of the first sub-top plate 8121 near the second sub-top plate 8122 and the end away from the second sub-top plate 8122, or one end of the first partition plate 85 connected to the top plate of the crossbeam 812 is connected at the connection between the first sub-top plate 8121 and the second sub-top plate 8122.

[0068] This arrangement allows for a reasonable connection position of the first partition plate 85, which can improve the deformation resistance of the first sub-cavity 8111 directly opposite the boss 82, thereby increasing the bending and compressive strength of the middle crossbeam 8. This makes the middle crossbeam 8 of this application more stable and reliable when the vehicle is subjected to a collision or bears a large dynamic load, thus improving the vehicle's safety performance.

[0069] In some embodiments of this utility model, such as Figure 4 As shown, the boss 82 includes: two boss side plates 822, the two boss side plates 822 being along a third direction (i.e. Figure 4 , 5 The beam body 81 also includes two beam side plates 814, spaced along a third direction (i.e., X direction as shown in Figure 6). Figure 4 , 5 The top plate 812, one side plate 814, the bottom plate 813, and the other side plate 814 of the crossbeam are connected end to end along the second direction (i.e., the X direction shown in Figure 6). Figure 3 , 4(shown in the Z direction), one of the beam side plates 814 is directly opposite to one of the boss side plates 822, and the first partition plate 85 is directly opposite to the other boss side plate 822.

[0070] Among them, the two boss side plates 822 are along the third direction (i.e. Figure 4 , 5 The interval (as shown in Figure 6) is along the third direction (i.e., the X direction). Figure 4 , 5 As shown in Figure 6 (in the X direction), two boss side plates 822 are spaced apart. In some embodiments of this application, the two boss side plates 822 are arranged in parallel. Two crossbeam side plates 814 are arranged along a third direction (i.e., ...). Figure 4 , 5 The interval (as shown in Figure 6) is along the third direction (i.e., the X direction). Figure 4 , 5 (As shown in the X direction of 6), the two crossbeam side plates 814 are spaced apart. In some embodiments of this application, the two crossbeam side plates 814 are arranged in parallel.

[0071] A top beam 812, a side beam 814, a bottom beam 813, and another side beam 814 are connected end-to-end. In some embodiments of this application, the top beam 812 corresponds to the bottom beam 813, and one side beam 814 corresponds to another side beam 814. These components are connected end-to-end to form a first cavity 811. In some embodiments of this application, the connection method between any two adjacent components can be, but is not limited to, welding or integral molding.

[0072] Along the second direction (i.e.) Figure 3 , 4 In the Z direction shown, one of the beam side plates 814 is directly opposite to one of the boss side plates 822, and the first partition plate 85 is directly opposite to the other boss side plate 822. As some embodiments of this application, along the second direction (i.e. Figure 3 , 4 (As shown in the Z direction), the beam side plate 814 near the lap plate 84 is directly opposite the boss side plate 822 near the lap plate 84, and the first partition plate 85 is directly opposite the boss side plate 822 away from the lap plate 84. As some embodiments of this application, the beam side plate 814 and the corresponding boss side plate 822 can be integrally formed.

[0073] This arrangement allows for a reasonable placement of the two boss side plates 822 and the two crossbeam side plates 814, thereby improving the bending and compressive strength of the middle crossbeam 8.

[0074] In some embodiments of this utility model, such as Figure 4As shown, the vehicle's middle crossbeam 8 also includes: a second partition plate (not shown in the figure), the second partition plate being connected between the first sub-top plate 8121 and the crossbeam side plate 814 connected to the first sub-top plate 8121, the second partition plate being connected to the second direction (i.e. Figure 3 , 4 The Z direction shown is perpendicular to the direction indicated.

[0075] In some embodiments of this application, one end of the second partition plate is connected to the first sub-top plate 8121, and the other end of the second partition plate is connected to the crossbeam side plate 814. Furthermore, the second partition plate is connected to the second direction (i.e., Figure 3 , 4 The Z direction shown is perpendicular to the second partition plate, meaning the normal to the second partition plate is perpendicular to the second direction (i.e., the Z direction shown). Figure 3 , 4 (The Z direction shown is parallel). As some embodiments of this application, the connection between the second partition plate and the first sub-top plate 8121 and the crossbeam side plate 814 can be, but is not limited to, welding or integral molding.

[0076] As some embodiments of this application, one end of the second partition plate connected to the first sub-top plate 8121 is connected between the end of the first sub-top plate 8121 near the second sub-top plate 8122 and the end away from the second sub-top plate 8122, or one end of the second partition plate connected to the first sub-top plate 8121 is connected at the connection between the first sub-top plate 8121 and the second sub-top plate 8122.

[0077] In some embodiments of this application, the first partition plate 85 and the second partition plate are staggered, for example, the first partition plate 85 and the second partition plate are orthogonally arranged. In some embodiments of this application, the connection method between the first partition plate 85 and the second partition plate can be, but is not limited to, welding or integral molding.

[0078] This arrangement allows the second partition plate, the side plate 814 of the crossbeam, and the first sub-top plate 8121 to form a triangular structure, which can significantly improve the structural strength and rigidity of the crossbeam body 81 and improve the reliability of the middle crossbeam 8.

[0079] In some embodiments of this utility model, such as Figure 4 As shown, the vehicle's middle crossbeam 8 also includes: a third partition plate 86, a boss 82 defining a second cavity 821, and the third partition plate 86 disposed in the second cavity 821 to divide the second cavity 821 into multiple second sub-cavities 8211.

[0080] The boss 82 defines the second cavity 821. As some embodiments of this application, the second cavity 821 is along the first direction (i.e. Figure 1 , 2 The Y-direction shown in Figures 3, 5, and 6 penetrates through the boss 82, meaning that the boss 82 is constructed as a hollow structure.

[0081] The third partition plate 86 is provided on the second cavity 821 to divide the second cavity 821 into multiple second sub-cavities 8211.

[0082] As some embodiments of this application, there are multiple third partition plates 86, each including at least one first sub-partition plate 861 and at least one second sub-partition plate 862, with the first sub-partition plate 861 and the second sub-partition plate 862 being arranged alternately.

[0083] As some embodiments of this application, the number of third partition plates 86 is multiple, and the multiple third partition plates 86 may include first sub-partition plates 861 and second sub-partition plates 862. The number of first sub-partition plates 861 may be one or more, and the number of second sub-partition plates 862 may be one or more. As some embodiments of this application, the first sub-partition plate 861 is along a third direction (i.e. Figure 4 , 5 Extending in the X direction (as shown in Figure 6), when there are multiple first sub-separators 861, the multiple first sub-separators 861 extend along the second direction (i.e., Figure 3 , 4 The second sub-separator 862 is arranged at intervals along the second direction (i.e., the Z-direction shown), and the second sub-separator 862 is arranged along the second direction (i.e., the Z-direction shown). Figure 3 , 4 Extending in the Z direction (as shown), when there are multiple second sub-separators 862, the multiple second sub-separators 862 extend along a third direction (i.e., Figure 4 , 5 The sub-separators 861 and 862 are arranged at intervals in the X direction (as shown in Figure 6). Furthermore, the first sub-separator 861 and the second sub-separator 862 are staggered, for example, the first sub-separator 861 and the second sub-separator 862 are orthogonal.

[0084] As some embodiments of this application, such as Figure 4 As shown, the plurality of third partitions 86 include a first sub-partition 861 and two second sub-partitions 862. As some embodiments of this application, the first sub-partition 861 is along a third direction (i.e., Figure 4 , 5 Extending in the X direction (as shown in Figure 6), both second sub-separators 862 extend along the second direction (i.e., Figure 3 , 4 Extending in the Z direction (as shown), the two second sub-separators 862 extend along the third direction (i.e., Figure 4 , 5 The sub-separators 861 and 862 are arranged at intervals in the X direction (as shown in Figure 6). Furthermore, the first sub-separator 861 and the second sub-separator 862 are orthogonally arranged.

[0085] This design can improve the structural strength of the boss 82, enhance its resistance to deformation, and thus improve the bending and compressive strength of the middle crossbeam 8. This makes the middle crossbeam 8 of this application more stable and reliable when the vehicle is subjected to a collision or a large dynamic load, thereby improving the vehicle's safety performance.

[0086] According to the present invention, the vehicle includes the middle crossbeam 8 of the vehicle described above. By providing the boss 82, the connection area between the middle crossbeam 8 and other components can be increased, making it easier to connect the middle crossbeam 8 with other components. This also makes the connection between the middle crossbeam 8 and other components tighter, which is beneficial for the middle crossbeam 8 to disperse collision energy to both sides, reduce the risk of stress concentration, and improve the safety performance of the vehicle. In addition, by having the crossbeam body 81 and the boss 82 jointly define the clearance space 83, other components of the vehicle can be accommodated through the clearance space 83, reducing the difficulty of arranging vehicle parts.
