[0050] The guide groove 1 is arranged under the radar mounting hole 31 of the vehicle roof outer panel 3. The edge of the guide groove 1 is connected to the bottom surface of the vehicle roof outer panel 3 to form a seal. The guide groove 1 is a downwardly recessed structure and a drainage through hole 11 is provided at the lowest point. The drainage component 2 is arranged under the guide groove 1. The drainage component 2 is provided with a connector 21 and a drainage pipe 22. The two ends of the connector 21 are respectively connected to the drainage through hole 11 and the top end of the drainage pipe 22 to form a seal, and the bottom end of the drainage pipe 22 is led out of the vehicle. The guide groove 1 in the embodiment of the present invention is a groove structure with an opening at the top. The top opening area of ​​the guide groove 1 is larger than the area of ​​the radar mounting hole 31 of the vehicle roof outer panel 3, and the edge of the guide groove 1 is connected to the bottom surface of the vehicle roof outer panel 3 to form a seal. After the external rainwater passes through the connection between the radar and the vehicle body and enters the radar mounting hole 31, the rainwater drips into the guide groove 1 and gathers into the drainage through hole 11 along the inner wall of the guide groove 1, and is finally led out of the vehicle through the drainage component 2.

The left side 14 of the groove is lower than the right side 15 of the groove in the height direction. The left and right height differences are used for diversion, so that rainwater is easily collected downward into the left side 14 of the groove. The drainage through hole 11 is arranged at the bottom of the left side 14 of the groove, and the surface where the drainage through hole 11 is located is flush with the left side 14 of the groove in the height direction, or lower than the left side 14 of the groove. When water accumulates in the guide groove 1, the water will flow from the right side 15 of the groove to the left side 14 of the groove under the action of gravity, and collect into the drainage through hole 11. The guide groove 1 has a simple structure and cooperates with the bottom surface of the vehicle roof outer panel 3 to form a seal, thereby improving the sealing performance of the drainage device.

In the embodiment of the present invention, D1 is 0.5 mm smaller than D0, so that the connector 21 can be installed from bottom to top and is not easy to tilt in the drainage through hole 11.

[0069] As an optional implementation, in an embodiment of the invention, see Fig.11 As shown, Fig.11 is the second cross section of the drainage structure, which passes through the central axis of the first annular flange 211 of the connector 21 and is located at the midpoint of the first buckle 214. The longitudinal cross section of each first buckle 214 is a structure that is narrow at the top and wide at the bottom. In the embodiment of the present invention, the first buckle 214 is a wedge-shaped structure, and the distance between the outer surfaces of the two oppositely arranged wedge-shaped structures is D2. The inner diameter D0 of the drainage through hole 11 is 0.5-1 mm smaller than D2. The wedge-shaped structure improves the stability of the cooperation between the first buckle and the guide groove.

[0070] As an optional implementation, in an embodiment of the invention, see Figure 7 and Fig.11As shown, the drainage component 2 is also provided with an annular sealing ring 23, which is sleeved on the outer circumference of two connecting pieces 213 that are arranged around and opposite to each other. The top surface of the annular sealing ring 23 fits with the lower surface of the guide groove 1, and the bottom surface of the annular sealing ring 23 fits with the top surface of the first annular flange 211, that is, the annular sealing ring 23 is nested between the first annular flange 211 and the guide groove 1. The main material of the annular sealing ring 23 is EPDM rubber, which is a compressible material. The inner diameter of the annular sealing ring 23 is D4, and the thickness is H. The thickness H before installation is 3-5mm, and after installation, it is compressed to a thickness H of 0.5-1mm, and sealing is achieved by compression, as shown in FIG. Fig.11 As shown, the dotted line is the annular sealing ring 23 before compression, at which time the annular sealing ring 23 interferes with the guide groove 1. The annular sealing ring provided between the first annular flange and the guide groove further improves the sealing performance of the drainage structure in the automobile.
