[0002] With the rapid development of the smart car market, the diversification of vehicle configuration has become an important consideration for manufacturers and consumers. As a high-precision sensing device, LiDAR plays a vital role in the intelligent driving system. LiDAR can accurately capture information about the surrounding environment by emitting laser beams and measuring the reflected light, providing important data support for smart driving cars. Most vehicles use skylight glass and panoramic sunroofs. The front crossbeam of the roof is used to improve the structural strength of the top of the vehicle. In order to ensure the beauty of the vehicle's appearance and prevent water from entering the vehicle, a decorative panel is often installed above the front crossbeam of the roof. Auxiliary driving modules such as LiDAR are often configured in high-end models and installed on the front crossbeam of the roof. The lower end of the radar usually needs to be connected and fixed to the body, and the gap and surface difference between the radar and the decorative panel need to be matched. In the current technical implementation, when the LiDAR is fixed on the front crossbeam of the roof, due to the long dimension chain and the need to consider aesthetics, there are a series of challenges in the matching of the front crossbeam of the roof and the decorative panel.

[0036] Figure 3 For a schematic diagram of the structure of a front crossbeam assembly installed on a vehicle body provided by an embodiment of the utility model, please refer to Figure 1 and Figure 3In this embodiment, the front cross beam assembly 10 includes a front cross beam inner plate 12 and a front cross beam outer plate 11 which are arranged in sequence. A gap is provided between the front cross beam outer plate 11 and the front cross beam inner plate 12 to avoid interference between the front cross beam outer plate 11 and the front cross beam inner plate 12. The first accommodating portion 111 of the front cross beam assembly 10 is provided on the front cross beam outer plate 11, and the second connecting hole 112 is provided on the front cross beam outer plate 11. The edges of the front cross beam outer plate 11 and the front cross beam inner plate 12 are fixed by welding. The front cross beam assembly 10 adopts a hot-formed steel plate, and the rigidity meets the performance requirements of the automobile. There is no need to additionally provide a supporting structure between the front cross beam outer plate 11 and the front cross beam inner plate 12. The front cross beam assembly 10 can ensure safety performance such as top pressure and NVH comfort.

[0037] Figure 4 This is a schematic diagram of the structure of the front cross beam outer plate provided by an embodiment of the utility model. Figure 1 , Figure 3 and Figure 4 In this embodiment, a first avoidance hole 121 is provided at a position corresponding to the second connection hole 112 on the front cross beam inner plate 12. The first avoidance hole 121 may be a square hole. The first avoidance hole 121 is used for avoidance when installing and fixing the decorative plate 20.

[0039] Furthermore, auxiliary driving modules such as radar are often configured in high-end models and installed on the roof crossbeam, while low-end models are not equipped with radar systems. This configuration difference leads to differences in the design and installation of trim panels between high-end cars and low-end cars. In traditional designs, for different configuration models with or without radar, manufacturers often need to design two different sets of beam structures to adapt to the trim panels of high-end and low-end models respectively, which not only increases the complexity of design and production, but also increases production costs. In low-end models, the glue-coated area 113 can be directly used to connect the trim panel and the front crossbeam assembly 10, so that the front crossbeam assembly 10 is sealed and fixed on the vehicle body 40. Therefore, the setting of the glue-coated area 113 allows a front crossbeam assembly 10 to be simultaneously adapted to the assembly of low-end models and high-end models, and has universality, thereby reducing production costs.
