[0022] like Figures 1 to 3 As shown, an embodiment of the present invention provides a front cabin crossbeam assembly, including a crossbeam 1, a first connecting block 2, and a second connecting block 3; the two ends of the crossbeam 1 are respectively used to connect two shock absorber seats of the vehicle; the first connecting block 2 is located in the middle of the crossbeam 1 and is used to connect the instrument panel crossbeam 1 of the vehicle; the two second connecting blocks 3 are respectively located at the two ends of the crossbeam 1 and are respectively used to connect the front frame of the vehicle.

[0023] It should be noted that the crossbeam 1, the first connecting block 2, and the second connecting block 3 can be extruded independently and then welded together. Specifically, each end of the crossbeam 1 can be provided with two connecting holes for connecting to the shock absorber seat, that is, each end of the crossbeam 1 can have two connection points at the shock absorber seat; the first connecting block 2 can be provided with one connecting hole for connecting to the instrument panel crossbeam 1, that is, the first connecting block 2 can have one connection point at the instrument panel crossbeam 1; the second connecting block 3 can be provided with one connecting hole for connecting to the front frame, that is, the second connecting block 3 can have one connection point at the front frame, for a total of 8 connection points, realizing the connection between the front compartment crossbeam assembly and the surrounding parts.

[0024] In this embodiment, the two ends of the crossbeam 1 can be used to connect the two shock absorber mounts of the vehicle, so that the front compartment crossbeam assembly has a connection point at the shock absorber mount. At the same time, the first connecting block 2 is located in the middle of the crossbeam 1 and can be used to connect the dashboard crossbeam 1, so that the front compartment crossbeam assembly has a connection point at the dashboard crossbeam 1. In addition, two second connecting blocks 3 are located at the two ends of the crossbeam 1 and can be used to connect the front frame, so that the front compartment crossbeam assembly has a connection point at the front frame. Thus, the entire front compartment crossbeam assembly can form multiple connection points with the surrounding parts through the crossbeam 1, the first connecting block 2 and the second connecting block 3. This can improve the connection stability and torsional stiffness of the front compartment crossbeam assembly, better resist the impact generated during vehicle driving, and thus improve the vehicle's handling stability.

[0025] Optionally, such as Figures 4 to 6 As shown, the crossbeam 1 gradually bends downward from the middle to both ends, and the lower side of the end of the crossbeam 1 is partially recessed to form a connecting plane 13, which is used to fit and connect with the shock absorber seat.

[0026] Specifically, the connecting plane 13 can be obtained by flattening the end of the crossbeam 1 after it has been extruded.

[0027] In this optional embodiment, by gradually bending the crossbeam 1 downwards from the middle to both ends, the crossbeam 1 can be made to have a two-dimensional arc curvature. This allows for the passage of some components in the forward compartment through the space created by the bend, effectively solving the space arrangement problem caused by the complex boundaries of surrounding components. Furthermore, the curved crossbeam 1 provides better overall torsional stiffness compared to a straight beam. Additionally, because the crossbeam 1 is curved, the lower surface of its ends is no longer flat, making it difficult to align with the upper surface of the shock absorber seat, which would affect the connection. Therefore, this solution partially recesses the lower surface of the ends of the crossbeam 1 to form a connecting plane 13. This allows the crossbeam 1 to align with the upper surface of the shock absorber seat through the connecting plane 13 when connected, ensuring a tight connection and improving the connection effect.

[0028] Furthermore, a notch 14 can be opened in the middle of the crossbeam 1, which can avoid some components in the forward compartment and prevent interference with these components.

[0029] Optionally, such as Figure 4 As shown, the crossbeam 1 is a hollow structure, and a first reinforcing rib plate 11 is formed inside the crossbeam 1 along its length direction. The first reinforcing rib plate 11 is connected to the front side wall and the rear side wall of the crossbeam 1 respectively.

[0030] Specifically, the crossbeam 1 can be extruded along its length.

[0031] In this optional embodiment, by setting the crossbeam 1 as a hollow structure, a lightweight design of the crossbeam 1 can be achieved, reducing material costs. At the same time, the first reinforcing rib 11 can provide support for the front and rear side walls, effectively preventing the crossbeam 1 from being crushed during installation, thereby improving the structural strength of the crossbeam 1. Thus, while ensuring structural strength, material costs can be reduced.

[0032] Optionally, such as Figure 5 and Figure 6 As shown, the end of the crossbeam 1 is provided with a first connecting hole 12. The first connecting hole 12 passes through the upper side wall of the crossbeam 1, the first reinforcing rib plate 11 and the lower side wall of the crossbeam 1 in sequence and passes through the connecting plane 13. The crossbeam 1 is used to connect the shock absorber seat through the first connecting hole 12.

[0033] It should be noted that two first connecting holes 12 can be opened at each end of the crossbeam 1, and the two first connecting holes 12 can be a round hole and an oblong hole, respectively.

[0034] In this optional embodiment, since the first connecting hole 12 is used to connect the crossbeam 1 to the shock absorber seat, based on this, by having the first connecting hole 12 pass through the upper side wall of the crossbeam 1, the first reinforcing rib plate 11 and the lower side wall of the crossbeam 1 in sequence and pass through the connecting plane 13, when the first connecting hole 12 is connected to the shock absorber seat by means of a connector such as a bolt, the design of passing through the upper side wall, the first reinforcing rib plate 11 and the lower side wall in sequence can ensure the installation firmness of the connector, thereby improving the connection strength between the crossbeam 1 and the shock absorber seat.

[0035] Optionally, such as Figures 7 to 10 As shown, the front side of the first connecting block 2 is fitted and connected to the rear side of the crossbeam 1, and the rear end of the first connecting block 2 is provided with a second connecting hole 23 arranged vertically; the front cabin crossbeam assembly also includes a first sleeve 4, which passes through the second connecting hole 23, and the first connecting block 2 is used to connect the instrument panel crossbeam 1 through the first sleeve 4.

[0036] It should be noted that the front side of the first connecting block 2 can be welded to the rear side of the crossbeam 1. Specifically, a first weld 24 is formed on each of the two edges of the front side of the first connecting block 2 to connect with the crossbeam 1. Furthermore, chamfers can be provided on the two edges of the front side of the first connecting block 2 to facilitate welding and improve welding strength.

[0037] In this optional embodiment, inserting the first sleeve 4 into the second connecting hole 23 can increase the strength of the first connecting block 2 near the second connecting hole 23. In this way, when the first connecting block 2 is connected to the instrument panel beam 1 through the first sleeve 4, the higher strength near the second connecting hole 23 can ensure the stability and strength of the connection between the first connecting block 2 and the instrument panel beam 1.

[0038] Optionally, such as Figures 7 to 9 As shown, the first connecting block 2 has a first cavity 21 that extends through the length of the crossbeam 1, and the first cavity 21 has a second reinforcing rib 22 that extends through it.

[0039] Specifically, the first connecting block 2 can be extruded and formed along the through direction of the first cavity 21.

[0040] In this optional embodiment, by forming a first cavity 21 inside the first connecting block 2 and providing a second reinforcing rib plate 22 inside the first cavity 21, the overall cross-section of the first connecting block 2 can be approximately H-shaped. This achieves both lightweight design of the first connecting block 2 and structural strength of the first connecting block 2.

[0041] Optionally, such as Figure 10 As shown, the second connecting hole 23 includes a first through hole and a second through hole arranged coaxially. The first through hole passes through the upper side wall of the first connecting block 2, and the second through hole passes through the lower side wall of the first connecting block 2. The lower outer edge of the first sleeve 4 is provided with a stepped surface 41. The lower end of the first sleeve 4 extends into the first cavity 21 through the first through hole, and the stepped surface 41 is engaged with the upper edge of the hole wall of the second through hole. The outer wall surface of the first sleeve 4 is welded to the outer surface of the upper side wall of the first connecting block 2.

[0042] Specifically, the outer wall of the first sleeve 4 and the outer surface of the upper side wall of the first connecting block 2 can be connected by an annular weld, that is, the outer wall of the first sleeve 4 is connected to the outer surface of the upper side wall of the first connecting block 2 by forming an annular second weld 42.

[0043] In this optional embodiment, because the stepped surface 41 is engaged with the upper edge of the second through hole wall, the first sleeve 4 cannot move axially or radially relative to the second connecting hole 23 under this engagement. In this way, the outer wall of the first sleeve 4 can be welded to the outer surface of the upper side wall of the first connecting block 2, thus ensuring sufficient connection stability between the first sleeve 4 and the first connecting block 2, without having to weld both the upper and lower side walls of the first sleeve 4 to the first connecting block 2. This reduces welding costs while ensuring connection stability.

[0044] Optionally, such as Figure 7 , Figure 11 , Figure 12 and Figure 13 As shown, the rear side of the second connecting block 3 is fitted and connected to the front side of the crossbeam 1. The front end of the second connecting block 3 is provided with a third connecting hole 33, which passes through the upper side wall and the lower side wall of the second connecting block 3 in sequence. The front compartment crossbeam assembly also includes a second sleeve 5, which passes through the third connecting hole 33. The second connecting block 3 is used to connect the front frame through the second sleeve 5.

[0045] It should be noted that the rear side of the second connecting block 3 can be welded to the front side of the crossbeam 1. Specifically, a third weld 34 is formed on both sides of the rear side of the second connecting block 3 to connect with the crossbeam 1. Furthermore, chamfers can be provided on both sides of the rear side of the second connecting block 3 to facilitate welding and improve welding strength.

[0046] In this optional embodiment, inserting the second sleeve 5 into the third connecting hole 33 can increase the strength of the second connecting block 3 near the third connecting hole 33. Thus, when the second connecting block 3 is connected to the front frame through the second sleeve 5, the higher strength near the third connecting hole 33 can ensure the stability and strength of the connection between the second connecting block 3 and the front frame.

[0047] Optionally, such as Figure 7 , Figure 11 and Figure 12 As shown, the interior of the second connecting block 3 is provided with a second cavity 31 that extends through the length of the crossbeam 1, and the second cavity 31 is provided with a third reinforcing rib plate 32 that extends through it.

[0048] Specifically, the second connecting block 3 can be extruded and formed along the through direction of the second cavity 31.

[0049] In this optional embodiment, by forming a second cavity 31 inside the second connecting block 3 and providing a third reinforcing rib 32 inside the second cavity 31, the overall cross-section of the second connecting block 3 can be approximately H-shaped. This achieves both a lightweight design for the second connecting block 3 and ensures its structural strength.

[0050] Optionally, such as Figure 13 and Figure 14 As shown, the lower end of the second sleeve 5 extends into the second cavity 31 and abuts against the inner surface of the lower side wall of the second connecting block 3, and the outer wall surface of the second sleeve 5 is welded to the outer surface of the upper side wall of the second connecting block 3.

[0051] Specifically, the outer wall surface of the second sleeve 5 and the outer surface of the upper side wall of the second connecting block 3 can be connected by an annular weld, that is, the outer wall surface of the second sleeve 5 is connected to the outer surface of the upper side wall of the second connecting block 3 by forming an annular fourth weld 51.

[0052] In this optional embodiment, since the lower end of the second sleeve 5 abuts against the inner surface of the lower sidewall of the second connecting block 3, the axial movement of the second sleeve 5 can be restricted. In this way, the outer wall surface of the second sleeve 5 can be welded to the outer surface of the upper sidewall of the second connecting block 3, which can ensure sufficient connection stability between the second sleeve 5 and the second connecting block 3, without having to weld both the upper and lower sidewalls of the second sleeve 5 to the second connecting block 3. Thus, welding costs can be reduced while ensuring connection stability.

[0053] This utility model provides a vehicle including the aforementioned front compartment crossbeam assembly. Since the vehicle includes the aforementioned front compartment crossbeam assembly, it possesses all the beneficial effects brought about by all embodiments of the aforementioned front compartment crossbeam assembly, which will not be elaborated upon here.

[0054] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
