[0040] Reference Figure 1 , Figure 2 According to one embodiment of the present invention, a vehicle 100 includes: a longitudinal beam assembly 10, a crossbeam connecting plate 20, and a crossbeam assembly 30.

[0041] The crossbeam connecting plate 20 is installed above the longitudinal beam assembly 10. The crossbeam assembly 30 is installed above the crossbeam connecting plate 20; wherein, the crossbeam connecting plate 20 is provided with a first connector 212 and a second connector 221, the first connector 212 connects to the crossbeam assembly 30, the second connector 221 connects to the longitudinal beam assembly 10, there are multiple second connectors 221, and the first connector 212 is located in the area enclosed by multiple second connectors 221.

[0042] In related technologies, in vehicle structural design, crossbeam assemblies are typically mounted on longitudinal beam assemblies as crucial support and connecting components to provide necessary structural strength and load-bearing capacity. However, in actual production, the manufacturing of longitudinal beam assemblies involves complex welding, stamping, and assembly processes, and their machining accuracy is affected by various factors, making it difficult to strictly control the dimensional and geometric tolerances. These machining errors are further amplified during the installation of the crossbeam assembly, resulting in significant deviations in its installation position and impacting the overall vehicle structural accuracy and stability.

[0043] Furthermore, the installation error of the crossbeam assembly not only affects its own structural strength and assembly quality, but also has a chain reaction on other components installed on the crossbeam assembly (such as the headlight assembly), further amplifying the assembly error and affecting the dynamic performance, safety and durability of the whole vehicle.

[0044] In this embodiment of the utility model, by installing a crossbeam connecting plate 20 on the longitudinal beam assembly 10 and fixing the crossbeam assembly 30 with the crossbeam connecting plate 20, it can be understood that the manufacturing of the crossbeam connecting plate 20 is simpler than that of the longitudinal beam assembly 10. The welding, stamping and assembly processes involved are simpler, and the processing accuracy is easier to control. This improves the deviation of the installation position of the crossbeam assembly 30, improves the accuracy and stability of the vehicle structure, and at the same time facilitates the installation of other components, avoids amplifying assembly errors, and improves the dynamic performance, safety and durability of the vehicle.

[0045] Specifically, the crossbeam connecting plate 20 is located above the longitudinal beam assembly 10, and the crossbeam assembly 30 is located above the crossbeam connecting plate 20. The three are stacked together for easy assembly.

[0046] Specifically, there are three second connectors 221, which are distributed around the first connector 212. The first connector 212 is located in the middle of the three second connectors 221, making the connection between the longitudinal beam assembly 10 and the transverse beam assembly 30 more stable.

[0047] According to the embodiment of the present utility model, the vehicle 100, by adding a crossbeam connecting plate 20, fixes the crossbeam assembly 30, thereby improving the deviation of the installation position of the crossbeam assembly 30, improving the accuracy and stability of the vehicle structure, reducing the accuracy requirements of the longitudinal beam assembly 10, reducing development costs, shortening the problem rectification cycle, improving stability, facilitating the installation of other components, avoiding amplification of assembly errors, improving the dynamic performance, safety and durability of the vehicle, and placing the first connecting member 212 in the middle of multiple second connecting members 221, the force is more balanced, improving overall stability and overall performance.

A tooling space 13 is provided between the fender 12 and the crossbeam assembly 30. The tooling space 13 is suitable for placing positioning tooling. During the assembly of the vehicle 100, the positioning tooling connects the fender 12 and the crossbeam connecting plate 20 respectively. The positioning tooling plays a positioning role, associates the fender 12 and the crossbeam connecting plate 20, shortens the dimensional chain link, and reduces the accuracy requirements of the longitudinal beam assembly 10.

[0077] Specifically, the fourth connector 58 extends along the Z direction, and the fifth positioning component 59 is an XY-direction positioning pin, which improves positioning stability and ensures the clearance surface difference.

[0078] In some specific embodiments, the headlight assembly 50 is made of PP + glass fiber GF30, which improves the strength and rigidity of the material and increases the reliability of the product. Structurally, the mounting point of the headlight assembly 50 is designed with a positioning structure that can achieve bidirectional adjustment in both X and Z directions. The X-direction is designed with a positioning scheme that allows for precise adjustment, achieving eight precise adjustment gradients (-1.0mm, -0.75mm, -0.5mm, -0.25mm, 0.25mm, 0.5mm, 0.75mm, and 1.0mm) by aligning the indicator mark 57 with different graduations. The Z-direction is designed with a positioning scheme that allows for coarse adjustment, achieving a rough adjustment within a range of 1.0mm by adjusting the nut and the first bracket 14 and the second bracket 52. At the same time, a crossbeam connecting plate 20 is added to the longitudinal beam assembly 10, and a positioning fixture is used to establish an X-direction precision association with the fender 12, shortening the dimensional chain link of the X-direction positioning at both ends of the headlight assembly 50. This design not only reduces the precision requirements of the longitudinal beam assembly by 10% to address the issue of the exquisite appearance of the headlight assembly, but also has advantages such as low development cost, short problem rectification cycle, and good stability.

[0079] In some specific embodiments, when the gap between the headlight assembly 50 and the hood does not meet the DTS design requirements after the headlight assembly 50 is properly assembled (i.e., the indicator mark 57 points to the center main etched line), the employee uses an electric wrench to loosen all the Z-axis tightening points of the headlight assembly 50, manually adjusts the X-axis position of the headlight assembly 50, and visually aligns the indicator mark 57 on the headlight assembly 50 with the different main and auxiliary etched lines on the grille mounting plate 40 to achieve precise X-axis adjustments in eight gradients: -1.0mm, -0.75mm, -0.5mm, -0.25mm, 0.25mm, 0.5mm, 0.75mm, and 1.0mm. After visually confirming that the gap between the headlight assembly 50 and the hood is uniform and qualified, all Z-axis tightening points are tightened sequentially to ensure the gap and parallelism requirements between the headlight assembly 50 and the hood are met.
