Thus, the first-step installation and fixation of the radar body 3 are realized.

[0043] Preferably, as Figures 5 to 7As shown, in the embodiment, a plurality of first mounting holes 302 are formed on one side of the radar body 3 facing the connecting cross beam 1. The number of the first mounting positions 101 is multiple, and the multiple first mounting positions 101 surround the middle area. The multiple first mounting holes 302 are arranged in one-to-one correspondence with the multiple first mounting positions 101. The radar body 3 can be mounted on the connecting cross beam 1 through the cooperation of the multiple first mounting holes 302 and the multiple first mounting positions 101. In this way, the second-step installation and fixation of the radar body 3 are realized. Through two-step fixation, the radar body 3 can be stably mounted on the front end frame 6, avoiding the problem of loosening and abnormal noise.

[0044] Preferably, as Figures 5 to 8 shown, in the embodiment, the number of the multiple first mounting positions 101 can be, for example, three.

The first sealing member 402 is arranged between the radar body 3 and the connecting cross beam 1. The first screw member 401 sequentially passes through the connecting cross beam 1 and the radar body 3 along the third direction S3. The first sealing member 402 can be, for example, a gasket, and the gasket can improve the NVH performance and can also avoid water leakage.

[0047] Preferably, as Figure 4 and Figure 8 shown, in the embodiment, a plurality of fourth mounting positions 102 are arranged at both ends of the connecting cross beam 1 in the first direction S1.

Six fourth mounting positions 102 and seven fourth mounting positions 102 are respectively arranged at both ends of the connecting cross beam 1 in the first direction S1 to correspond to the multiple third mounting positions 203 of the decorative plate 2. Similarly, the number of the third mounting positions 203 is multiple, and the multiple third mounting positions 203 are arranged in one-to-one correspondence with the multiple fourth mounting positions 102. An installation position for the radar body 3 is arranged in the middle area of the connecting cross beam 1, and the radar body 3 is arranged here.

[0048] Preferably, in the embodiment, the distance between two adjacent fourth mounting positions 102 is less than 200 mm. Such a setting is to ensure the stability of the connection and avoid looseness and abnormal noise.

[0049] Preferably, in the embodiment, the distance between two adjacent first mounting positions 101 is also less than 200 mm. Since the position connection lines of the three first mounting positions 101 form a triangle, the distance between each two adjacent first mounting positions 101 is less than 200 mm to ensure the stable installation of the radar body 3.

[0050] Preferably, as Figure 4 、 Figure 8 、 Figure 10 、 Figure 11 and Figure 13 shown, in the embodiment, the third mounting position 203 is connected to the fourth mounting position 102 through a second connecting member. Both the third mounting position 203 and the fourth mounting position 102 can be formed into a hole-like structure, and the second connecting member can pass through these two hole-like structures at the same time to realize the fixed connection between the decorative plate 2 and the connecting cross beam 1.

[0051] Preferably, as Figure 4 、 Figure 8 、 Figure 10 、 Figure 11 and Figure 13 shown, in the embodiment, the second connecting member may include a second nut member 501, a second screw member 502 and a second sealing member 503. The second sealing member 503 is arranged between the connecting cross beam 1 and the decorative plate 2. The second screw member 502 passes through the third mounting position 203 and the fourth mounting position 102, and the second nut member 501 is sleeved on the second screw member 502 along the third direction S3. The second sealing member 503 can be, for example, a sealing gasket, and the sealing gasket can improve the NVH performance and at the same time can avoid water leakage.

[0052] The assembly process of the connection structure at the top of the front end of the vehicle is as follows: As Figure 6 shown, the radar body 3 can be installed on the second mounting position 202 of the decorative plate 2 through two connecting ears 301. As Figure 9 shown, the decorative plate 2 is along Figure 9It is placed on the connecting cross beam 1 in the direction indicated by the arrow (i.e., the direction from above the vehicle to below the vehicle), and then the decorative panel 2 is connected to the connecting cross beam 1 using the first connecting member. Since the number of the fourth mounting positions 102 and the third mounting positions 203 is thirteen each, thirteen first connecting members can be used. Finally, the radar body 3 is connected to the connecting cross beam 1 using the second connecting member. Since the number of the first mounting holes 302 and the first mounting positions 101 is three each, three second connecting members can be used. During assembly, both the first connecting member and the second connecting member are connected and assembled along the third direction S3, and the third direction S3 can be, for example, the direction extending from the bottom of the vehicle towards the top. In this way, both the first connecting member and the second connecting member can be arranged inside the vehicle body, improving the aesthetics.

[0053] The connecting structure at the top of the front end of the vehicle can ensure that the radar body and the decorative panel are firmly installed. The radar body is connected first, and then the decorative panel is fixedly connected to the connecting cross beam, thereby making the overall structure reliable and the installation stable, without looseness and abnormal noise. Due to the special assembly method during assembly, the connecting members can be hidden inside the vehicle body, which can improve the NVH performance of the vehicle while enhancing the aesthetics of the vehicle. Also, because the decorative panel and the radar body are firmly installed, there will be no phenomena such as water leakage or dust ingress, further improving the user experience of the passengers.
