This results in significant cumulative tolerances between these components after connection, and the low rigidity of the LiDAR mounting area makes it prone to shaking and distortion.

[0035] To address the related technical problems, this application provides a vehicle that includes the vehicle roof assembly described below.

[0036] To address the related technical problems, this application also provides a vehicle roof assembly, for details please refer to [link / reference needed]. Figure 1 and Figure 2 , Figure 1This is a structural schematic diagram of an embodiment of the vehicle roof assembly provided in this application. Figure 2 yes Figure 1 The diagram shows the disassembled structure of the vehicle roof assembly.

[0037] The vehicle roof assembly 10 includes a radar component 100, an integrated roof 200, a roof crossbeam 300, and a support member 400. The integrated roof 200 includes an integrally formed mounting portion 210 and a vehicle roof 220. The roof crossbeam 300 is located on one side of the mounting portion 210 and connected to the mounting portion 210, forming a mounting cavity 310 with the integrated roof 200. The support member 400 is disposed in the mounting cavity 310 and connects the mounting portion 210 and the roof crossbeam 300. The mounting portion 210 includes a radar mounting area 211 with a radar mounting hole 212. The radar component 100 is located on the side of the mounting portion 210 away from the roof crossbeam 300, and the radar component 100 is fixedly connected to the support member 400 through the radar mounting hole 212.

[0038] The radar assembly 100 includes a housing and a laser assembly disposed inside the housing. The laser assembly may include a laser emitter and a laser receiver. The laser emitter emits a laser, and the emitted laser is reflected by an object along the laser's emission path so that it can be received by the laser receiver, thereby enabling object detection.

[0039] The integrated roof cover 200 includes a mounting portion 210 and a vehicle roof cover 220, which are integrally die-cast and located on the top of the vehicle. The mounting portion 210 supports the radar assembly 100. The vehicle roof cover 220 can be a closed roof cover, a small sunroof-type roof cover, or a panoramic sunroof-type roof cover. In this embodiment, the vehicle roof cover 220 is a closed roof cover, which may include sheet metal covering the top of the vehicle to reduce the risk of foreign objects intruding into the vehicle's interior cabin and to provide consumers with a vehicle configuration featuring a closed roof cover and lidar.

[0040] The profile of the top cover crossbeam 300 can match the profile of the mounting portion 210, and the top cover crossbeam 300 is disposed on the side of the mounting portion 210 opposite to the radar assembly 100. Specifically, the radar assembly 100 is disposed on the outer side of the mounting portion 210, and the top cover crossbeam 300 is disposed on the inner side of the mounting portion 210. The top cover crossbeam 300 may have a mounting groove with the groove opening facing the mounting portion 210. The ends of the two opposite side walls of the mounting groove are provided with flanges that connect to the mounting portion 210. The flanges of the two side walls are used to connect with the mounting portion 210, thereby forming a mounting cavity 310 between the top cover crossbeam 300 and the mounting portion 210. The arrangement of the top cover crossbeam 300 can improve the structural strength and rigidity of the vehicle roof assembly 10 at the mounting portion 210 position and reduce the risk of the radar assembly 100 shaking.

[0041] A support member 400 is disposed within the mounting cavity 310. The support member 400 connects the top cover beam 300 and the mounting portion 210, so that the support member 400 is supported between the top cover beam 300 and the mounting portion 210. The mounting portion 210 has a radar mounting area 211. The radar assembly 100 and the support member 400 are both disposed opposite to the radar mounting area 211. The mounting portion 210 has a radar mounting hole 212 in the radar mounting area 211. The radar assembly 100 is fixedly connected to the support member 400 through the radar mounting hole 212.

[0042] Through the above embodiments, the integrated roof 200 includes an integrally formed mounting portion 210 and a vehicle roof 220, with the mounting portion 210 connected to the roof crossbeam 300. Within the radar mounting area 211 of the mounting portion 210, the support member 400 is supported between the roof crossbeam 300 and the mounting portion 210, thereby improving the rigidity of the mounting portion 210 in the radar mounting area 211. The radar assembly 100 is located within the radar mounting area 211 of the mounting portion 210 and is connected to the mounting portion 210 and the support member 400. This results in better matching between the various components of the vehicle roof assembly 10, further improving the rigidity of the vehicle roof assembly 10 in the radar mounting area 211, reducing the risk of detection distortion caused by insufficient rigidity of the radar assembly 100 at the mounting position, and improving the detection accuracy of the radar assembly 100.

[0043] See Figure 3 , Figure 3 yes Figure 2 A schematic diagram of one embodiment of the support member is shown.

[0044] In some embodiments, the support member 400 includes a mounting body 410, which includes two spaced-apart first reinforcing bosses 411. Each of the two first reinforcing bosses 411 has a first connecting boss 412 protruding toward the mounting portion 210. A first connecting boss 412 is also provided between the two first connecting bosses 412. The three first connecting bosses 412 are arranged in a triangle and are connected to the side of the mounting portion 210 away from the radar assembly 100. At least two of the first connecting bosses 412 have through holes 413 corresponding to the radar mounting holes 212 for fixed connection with the radar assembly 100.

[0045] The support member 400 includes a mounting body 410 for connection with the mounting portion 210 and the radar assembly 100. The mounting body 410 has two spaced-apart first reinforcing bosses 411, each protruding from the mounting body 410 toward the mounting portion 210. The two first reinforcing bosses 411 may be spaced apart along the length of the top cover beam 300, which can also be understood as the width direction of the vehicle. Alternatively, in some other embodiments, the two first reinforcing bosses 411 may also be spaced apart along the width of the top cover beam 300, which can also be understood as the length direction of the vehicle. Each of the two first reinforcing bosses 411 is provided with a first connecting boss 412. The first connecting boss 412 is a boss that protrudes from the end face of the first reinforcing boss 411 towards the mounting part 210. The size of the first connecting boss 412 is smaller than the size of the first reinforcing boss 411, thereby forming a multi-layered stepped combination structure between the first reinforcing boss 411 and the first connecting boss 412, which can effectively improve the structural strength of the support member 400. The two first connecting bosses 412 provided on the first reinforcing boss 411 are provided with through holes 413. The through holes 413 are correspondingly provided with the radar mounting holes 212 of the mounting part 210, so that the radar assembly 100 can be connected to the mounting body 410 of the support member 400 through the radar mounting holes 212 and the through holes 413. This allows the radar assembly 100 to be fixedly connected to the first connecting boss 412, which can effectively improve the overall structural strength of the radar mounting area 211, and also improve the rigidity at the mounting point of the radar assembly 100, reducing the risk of detection distortion of the radar assembly 100.

[0046] Furthermore, a first connecting boss 412 is provided between the two first connecting bosses 412 located on the two first reinforcing bosses 411. The three first connecting bosses are arranged in a triangle. The side of the three first connecting bosses 412 closest to the mounting part 210 is connected to the mounting part 210. The three first connecting bosses 412 can be screwed to the mounting part 210 by fasteners; or welded; or some of the first connecting bosses 412 can be screwed and some of the first connecting bosses 412 can be welded. This can further improve the structural stability and rigidity of the vehicle roof assembly 10 in the radar mounting area 211.

[0047] See Figure 4 , Figure 4 yes Figure 2 The diagram shows a structural schematic of one embodiment of the integrated top cover.

[0048] In some embodiments, in the radar mounting area 211 of the mounting part 210, the mounting part 210 includes a second reinforcing boss 230, the second reinforcing boss 230 and the first reinforcing boss 411 are spaced apart, the second reinforcing boss 230 is provided with two spaced second connecting bosses 240, the two second connecting bosses 240 are provided with radar mounting holes 212, and each first connecting boss 412 is connected to a corresponding second connecting boss 240.

[0049] The mounting section 210 includes a second reinforcing boss 230, which is disposed in the radar mounting area 211 of the mounting section 210. The second reinforcing boss 230 is a boss that protrudes from the mounting section 210 toward the radar assembly 100, providing a reference platform for the radar assembly 100. The second reinforcing boss 230 has two second connecting bosses 240, which are connected one-to-one with the two first connecting bosses 412 disposed on the two first reinforcing bosses 411, and the second reinforcing bosses 230 and the first reinforcing bosses 411 are spaced apart. Therefore, the second reinforcing boss 230 and the first reinforcing boss 411 are connected only by two second connecting bosses 240 and two first connecting bosses 412, so that the first reinforcing boss 411 and the second reinforcing boss 230 form a bridge-like structure, which can effectively improve the structural rigidity between the support member 400 and the mounting part 210. The radar assembly 100 is also connected to the mounting body 410 through two second connecting bosses 240 and two first connecting bosses 412, thereby effectively improving the stability and rigidity of the fixed part of the radar assembly 100 and reducing the risk of distortion of the radar assembly 100.

[0050] In some embodiments, the two first connecting bosses 412 each have one and two radar mounting holes 212, the three radar mounting holes 212 are arranged in a triangle, and the two second connecting bosses 240 have three through holes 413 corresponding to the three radar mounting holes 212. The radar assembly 100 is connected to the mounting part 210 and the support member 400 through the three radar mounting holes 212 and the three through holes 413.

[0051] For example, a first connecting boss 412 disposed in one of the first reinforcing bosses 411 has a through hole 413, and a first connecting boss 412 disposed in the other first reinforcing boss 411 has two through holes 413. The two through holes 413 disposed in one of the first connecting bosses 412 are spaced apart in a direction perpendicular to the distance between the two first reinforcing bosses 411, so that the three through holes 413 are arranged in a triangle. Two second connecting bosses 240 are disposed corresponding to the two first connecting bosses 412 disposed in the two first reinforcing bosses 411, and the two second connecting bosses 240 have three radar mounting holes 212 corresponding to the three through holes 413 of the two first connecting bosses 412. The radar assembly 100 is connected to the mounting part 210 and the support member 400 through the three radar mounting holes 212 and the three through holes 413 arranged in a triangle. Therefore, the three first connecting bosses 412 are arranged in a triangle and are connected to the mounting part 210. The two first connecting bosses 412 and the two second connecting bosses 240 are respectively provided with three through holes 413 and three radar mounting holes 212 arranged in a triangle. The triangle formed by the three through holes 413 intersects with the triangle formed by the three first connecting bosses 412, thereby further improving the structural strength and rigidity of the vehicle roof assembly 10 in the radar mounting area 211, improving the stability of the radar assembly 100 fixed in the radar mounting area 211, and reducing the risk of detection distortion of the radar assembly 100.

[0052] In some embodiments, the support member 400 includes a first support body 420 connected to the mounting body 410. The mounting body 410 is spaced apart from the bottom wall of the top cover beam 300. One end of the mounting body 410 away from the first support body 420 is connected to one side wall of the top cover beam 300. The other side wall of the top cover beam 300 is connected to the other end of the first support body 420. The side of the first support body 420 is also connected to the bottom wall of the top cover beam 300.

[0053] The support member 400 includes a mounting body 410 and a first support body 420, which are connected in the width direction of the roof beam 300. Specifically, one end of the mounting body 410 is connected to a side wall of the roof beam 300, which is located on the side of the roof beam 300 away from the vehicle roof 220. The first support body 420 is connected to the end of the mounting body 410 away from the side wall in the width direction of the roof beam 300. The first support body 420 extends in the width direction of the roof beam 300, and its side is connected to the bottom wall of the roof beam 300. The end of the first support body 420 away from the mounting body 410 is also connected to another side wall opposite to the side wall of the roof beam 300. Therefore, the mounting body 410 and the bottom wall of the top cover beam 300 are spaced apart, and one side of the first support body 420 is connected to the bottom wall of the top cover beam 300, so that the mounting body 410 and the first support body 420 form a concave-convex structure. The mounting body 410 and the first support body 420 work together to support the two opposite side walls of the top cover beam 300, thereby improving the structural strength of the support member 400 itself, improving the overall structural rigidity of the support member 400 and the top cover beam 300, improving the stability of the radar assembly 100, and reducing the risk of detection distortion of the radar assembly 100.

[0054] In some embodiments, the first support body 420 includes a first reinforcing rib 421, which extends in a direction perpendicular to the two first reinforcing protrusions 411 spaced apart. The two first reinforcing protrusions 411 are spaced apart to form a second reinforcing rib 422, which extends in the same direction as the first reinforcing rib 421, and the first reinforcing rib 421 and the second reinforcing rib 422 are arranged opposite to each other.

[0055] Two first reinforcing protrusions 411 are spaced apart in a direction perpendicular to the two sidewalls to form a second reinforcing rib 422 between the two first reinforcing protrusions 411. The second reinforcing rib 422 extends in the direction perpendicular to the two sidewalls, which can be understood as the width direction of the top cover beam 300. The first support body 420 includes a first reinforcing rib 421, which extends in a direction perpendicular to the spaced first reinforcing protrusions 411, and the first reinforcing rib 421 and the second reinforcing rib 422 are arranged opposite to each other in the direction perpendicular to the two sidewalls. Of course, in some other embodiments, the first reinforcing rib 421 and the second reinforcing rib 422 may also be connected in the direction perpendicular to the two sidewalls. Thus, the first reinforcing rib 421 of the first support body 420 and the second reinforcing rib 422 of the mounting body 410 extend in the same direction and are arranged opposite to each other, so that the first reinforcing rib 421 and the second reinforcing rib 422 can jointly improve the structural strength of the support member 400, thereby improving the stability of the radar assembly 100 in the direction perpendicular to the two sidewalls and reducing the risk of detection distortion of the radar assembly 100. In this embodiment, in addition to the two first connecting bosses 412 disposed on the two first reinforcing bosses 411, another first connecting boss 412 may be disposed between the first reinforcing rib 421 and the second reinforcing rib 422, so that the first reinforcing rib 421 is connected to the second reinforcing rib 422 through the first connecting boss 412, thereby enabling the first reinforcing rib 421, the second reinforcing rib 422 and the corresponding first connecting boss 412 to cooperate with each other, further improving the structural strength of the support member 400.

[0056] In some embodiments, the support member 400 may further include at least two second support bodies, which are disposed at both ends of the mounting body 410 in the spaced direction of the two first reinforcing bosses 411. The ends of the two second support bodies away from the mounting body 410 extend toward the bottom wall of the top cover beam 300 and are connected to the bottom wall of the top cover beam 300, thereby supporting the two second support bodies between the bottom wall of the top cover beam 300 and the mounting body 410, further improving the structural strength of the support member 400.

[0057] See Figure 5 , Figure 5 yes Figure 2 A partial cross-sectional view of the first sealing strip shown.

[0058] In some embodiments, the vehicle roof assembly 10 includes a trim panel assembly 500 and a first sealing strip 510. The trim panel assembly 500 is connected to the side of the mounting portion 210 away from the support member 400. The first sealing strip 510 is disposed around the edge of the mounting portion 210 and is located between the trim panel assembly 500 and the mounting portion 210. The first sealing strip 510 is provided with a water guide groove 511 and a water guide outlet that communicate with each other. The opening of the water guide groove 511 faces the trim panel assembly 500, and the water guide outlet is disposed on the side of the first sealing strip 510 away from the vehicle roof 220.

[0059] The trim panel assembly 500 is connected to the side of the mounting portion 210 opposite to the support member 400. The outline of the trim panel assembly 500 matches the outline of the mounting portion 210, thereby covering the side of the mounting portion 210 opposite to the support member 400 and the radar assembly 100 disposed on that side. Specifically, the trim panel assembly 500 includes a mounting protrusion corresponding to the radar mounting area 211, thereby forming a radar mounting space between the mounting protrusion and the mounting portion 210, within which the radar assembly 100 is located. The vehicle roof assembly 10 also includes a first sealing strip 510, which is disposed around the edge of the mounting portion 210, or possibly around the edge of the trim panel assembly 500. The first sealing strip 510 is disposed between the trim panel assembly 500 and the mounting portion 210, thereby reducing the risk of liquid entering the interior of the vehicle roof assembly 10 from the gap between the mounting portion 210 and the trim panel assembly 500. The first sealing strip 510 is also provided with interconnected water guide grooves 511 and water guide ports. The water guide grooves 511 are arranged along the sealing direction of the first sealing strip 510, with the opening of the water guide grooves 511 facing the trim assembly 500. The water guide ports are located on the side of the first sealing strip 510 away from the vehicle roof 220, communicating with the water guide grooves 511 and with the external space, which refers to the vehicle's external environment. Therefore, even if liquid enters the gap between the trim assembly 500 and the mounting portion 210, the liquid can be discharged along the water guide grooves 511 and through the water guide ports, thereby reducing the risk of damage to the radar assembly 100. Multiple water guide ports can be provided at intervals on the side of the first sealing strip 510 away from the mounting portion 210, thereby increasing the drainage capacity of the water guide grooves 511.

[0060] In some embodiments, the trim panel assembly 500 has a sealing protrusion on the side facing the first sealing strip 510. The sealing protrusion is arranged along the direction of the water guide groove 511 and is embedded in the sealing groove 513. This improves the sealing effect between the trim panel assembly 500 and the first sealing strip 510, restricts the position of the first sealing strip 510, reduces the possibility of displacement of the first sealing strip 510, and allows liquid to be discharged through the water guide groove 511 and the water outlet.

[0061] In some embodiments, the vehicle roof assembly 10 includes a second sealing strip disposed inside the first sealing strip 510 and also between the mounting portion 210 and the trim assembly 500, thereby providing a second layer of protection for the seal between the mounting portion 210 and the trim assembly 500, further reducing the risk of water ingress into the vehicle roof assembly 10. In this embodiment, the mounting portion 210 may be inclined in the opposite direction of the two side walls. Specifically, the side of the mounting portion 210 closer to the vehicle roof 220 is higher than the side of the mounting portion 210 farther from the vehicle roof 220. The second sealing strip has water inlets penetrating the two opposing surfaces of the second sealing strip in the opposite direction of the two side walls, and the water inlets communicate with the water guides of the first sealing strip 510. Thus, even if liquid enters the mounting portion 210, it can be discharged in a timely manner along the mounting portion 210 and through the water inlets and water guides, reducing the risk of damage to the radar assembly 100.

[0062] In some embodiments, the vehicle roof assembly 10 further includes a third sealing strip. The radar assembly 100 includes a light-emitting end 110, and the mounting protrusion of the trim assembly 500 is provided with a light-emitting port 520. The light-emitting end 110 includes a mask and an abutment portion disposed around the periphery of the mask. The mask protrudes from the abutment portion and is located within the light-emitting port 520 so that laser light can be emitted from the mask. The third sealing strip is disposed around the abutment portion and is located between the inner side of the light-emitting port 520 and the abutment portion. Thus, the third sealing strip can seal the light-emitting port 520 and the light-emitting end 110, reducing the risk of water ingress between the radar assembly 100 and the trim assembly 500. A connecting strip may also be provided on the side of the third sealing strip near the first sealing strip 510. The connecting strip is used to connect the third sealing strip and the first sealing strip 510 so that the first sealing strip 510 and the third sealing strip are integrated, making it easier to install the sealing strip. There may be multiple connecting strips, which are spaced apart.

[0063] In some embodiments, the first sealing strip 510 includes a sealing body 512 and a sealing groove 513. The sealing groove 513 and the water guide groove 511 are disposed on opposite sides of the sealing body 512, and the opening of the sealing groove 513 faces the mounting portion 210.

[0064] The first sealing strip 510 includes a water guiding groove 511, a sealing body 512, and a sealing groove 513. The water guiding groove 511 and the sealing groove 513 are disposed on opposite sides of the sealing body 512 in the direction from the trim assembly 500 to the mounting portion 210. The opening of the water guiding groove 511 faces the trim assembly 500, and the opening of the sealing groove 513 faces the mounting portion 210. Thus, when the first sealing strip 510 is interference-fitted between the trim assembly 500 and the mounting portion 210, the sidewall of the sealing groove 513 can deform. The sealing groove 513 can increase the contact area between the first sealing strip 510 and the mounting portion 210, thereby further improving the sealing performance between the first sealing strip 510 and the mounting portion 210. In addition, the sealing groove 513 is also connected to the water inlet. When a large amount of liquid is inside the water inlet 511, the sealing groove 513 can also be used to store the liquid when the water inlet cannot drain the liquid in time. This has a buffering effect on the rapidly increasing liquid, reducing the risk of liquid volume being stored in the space between the mounting part 210 and the trim assembly 500, and reducing the risk of the radar assembly 100 being damaged by water accumulation.

[0065] In some embodiments, the trim panel assembly 500 includes a trim panel outer shell and a trim panel inner shell. The trim panel inner shell has a plurality of limiting holes that penetrate both opposite surfaces of the trim panel inner shell and are distributed throughout the trim panel. The trim panel outer shell has a plurality of limiting strips that match the multiple limiting holes, with each limiting strip inserted into one of the limiting holes to position the trim panel inner shell and the trim panel outer shell. The trim panel inner shell and the trim panel outer shell can be connected to each other by adhesive bonding or by snap-fit ​​connection. The trim panel outer shell is smoothly connected to the vehicle roof 220, thereby giving the vehicle roof assembly 10 a streamlined appearance and reducing the risk of liquid entering the interior of the vehicle roof assembly 10. In this embodiment, the multiple snap-fit ​​holes can be arranged in different directions, for example, some snap-fit ​​holes are arranged along the length direction of the trim panel inner shell and some snap-fit ​​holes are arranged along the width direction of the trim panel inner shell, thereby limiting the trim panel inner shell and the trim panel outer shell in different directions. The snap-fit ​​strip may include a main strip and sub-strips disposed on both sides of the main strip. The number of sub-strips may be multiple, thereby improving both the structural strength of the snap-fit ​​strip and the snap-fit ​​effect. Multiple snap-fit ​​members are also distributed on the side of the inner panel facing the mounting portion 210. These multiple snap-fit ​​members surround the area of ​​the first sealing strip 510. The mounting portion 210 is provided with snap-fit ​​holes that match the multiple snap-fit ​​members. Each snap-fit ​​strip is snapped into one snap-fit ​​hole, thereby ensuring a stable connection between the trim assembly 500 and the mounting portion 210, and also providing better sealing between the trim assembly 500, the first sealing strip 510, and the mounting portion 210.

[0066] In some embodiments, the radar assembly 100 includes a housing and three fasteners connected to the outside of the housing. The three fasteners pass through three radar mounting holes 212 and three through holes 413 to securely connect the radar assembly 100 to the support member 400 and the mounting portion 210. The fasteners may include bolts, sleeves, and shims. The sleeves and shims are connected, and the bolts pass through the three through holes 413 and the three radar mounting holes 212, and are inserted within the sleeves and shims to securely connect the housing to the mounting body 410 and the support member 400. The housing and the mounting portion 210 are spaced apart, and the shims are located between the housing and the mounting portion 210. This reduces the risk of the radar assembly 100 directly contacting liquids.

[0067] See Figures 6 to 8 , Figure 6 Yes Figure 2 A schematic diagram of one embodiment of the decorative panel assembly shown. Figure 7 The diagram shown is an enlarged structural schematic of the trim assembly at the dashed box I. Figure 8 yes Figure 2 A schematic diagram of one embodiment of the radar assembly shown.

[0068] In some embodiments, the trim assembly 500 is provided with a light outlet 520 and two first limiting portions 530. The radar assembly 100 includes a light-emitting end 110 and a fixing component 120. The light-emitting end 110 and the fixing component 120 are located at both ends of the radar assembly 100. The light-emitting end 110 is partially embedded in the light outlet 520. A plurality of second limiting portions 540 are provided on the inner side of the light outlet 520 around the periphery of the light outlet 520 to limit the light-emitting end 110. The two first limiting portions 530 are spaced apart in the width direction of the radar assembly 100 to limit the radar assembly 100 between the two first limiting portions 530. The fixing component 120 is connected to the trim assembly 500.

[0069] The radar assembly 100 can be first installed on the trim panel assembly 500, and then connected to the mounting part 210. Exemplarily, the trim panel assembly 500 also includes two first limiting parts 530, and the radar assembly 100 also includes a fixing part 120 located at the end of the radar assembly 100 away from the light-emitting end 110. A plurality of second limiting parts 540 are provided inside the light-emitting port 520, surrounding the periphery of the light-emitting port 520. The light-emitting end 110 is located between the plurality of second limiting parts 540, so that the plurality of second limiting parts 540 limit the radar assembly 100 from the periphery of the light-emitting end 110. Two first limiting portions 530 are located in the middle of the radar assembly 100, and are spaced apart in the width direction of the radar assembly 100. The radar assembly 100 is located between the two first limiting portions 530, thereby limiting the radar assembly 100 by the two first limiting portions 530. The width direction of the radar assembly 100 can also be understood as the length direction of the top cover beam 300. In addition, the fixing component 120 is also fixedly connected to the trim panel assembly 500. Thus, the two first limiting portions 530 and the plurality of second limiting portions 540 limit the radar assembly 100 in multiple directions. The radar assembly 100 is fixedly connected to the trim panel assembly 500 through the fixing component 120, thereby simplifying the installation process between the radar assembly 100 and the trim panel assembly 500 and providing a better fixing effect.

[0070] In summary, the integrated roof 200 includes an integrally formed mounting portion 210 and a vehicle roof 220, with the mounting portion 210 connected to the roof crossbeam 300. Within the radar mounting area 211 of the mounting portion 210, the support member 400 is supported between the roof crossbeam 300 and the mounting portion 210, thereby improving the rigidity of the mounting portion 210 in the radar mounting area 211. The radar assembly 100 is located within the radar mounting area 211 of the mounting portion 210 and is connected to the mounting portion 210 and the support member 400. This results in better matching between the various components of the vehicle roof assembly 10, further improving the rigidity of the vehicle roof assembly 10 in the radar mounting area 211, reducing the risk of detection distortion caused by insufficient rigidity of the radar assembly 100 at the mounting position, and improving the detection accuracy of the radar assembly 100.
