[0022] Radar 3 is installed into radar sleeve 4 from bottom to top. There is a gap between the inner wall of radar sleeve 4 and the outer surface of radar 3. A glue-filling port is formed between adjacent elastic side plates 42. Sealant is poured into the inner cavity of radar sleeve 4 from the bottom to fill it. The leak-proof glue component 9 can be a ring-shaped foam gasket, a ring-shaped soft rubber gasket, or glue (dispensing sealant), etc., to prevent glue from leaking out from the gap between the limiting ring 41 and radar 3 when glue is poured into radar sleeve 4. In this embodiment, the leak-proof glue component 9 is preferably a ring-shaped foam gasket.

[0023] The waterproof soft rubber gasket 7 is fitted onto the upper end of the radar 3, specifically onto the outside of the radar 3 detector. The inner hole of the waterproof soft rubber gasket 7 forms an interference fit with the outer diameter of the radar 3 detector. Two annular grooves are provided on the inner wall of the waterproof soft rubber gasket 7 along the axial direction of the inner hole, forming multiple sealing sections with the radar.

[0024] The waterproof soft rubber pad 7 includes a base plate 71, a first protrusion 72 extending upward from the top surface of the base plate 71, and a second protrusion 73 extending upward from the top surface of the first protrusion 72; the top surface of the base plate 71 is provided with three (or one, two, or more) first water-blocking rings 74 from the inside out, the first water-blocking rings 74 are in close contact with the bottom surface of the limiting ring 41; the bottom surface of the base plate 71 is provided with two (or one, two, or more) second water-blocking rings 75 from the inside out; the top surface of the radar sleeve 4 is provided with two (or one, two, or more) waterproof grooves 46 from the inside out, and the two second water-blocking rings 75 are respectively pressed tightly in the two waterproof grooves 46; the top surface of the first protrusion 72 is provided with one (or more) third water-blocking rings 76, the third water-blocking ring 76 is in close contact with the canopy sheet metal 1, and the second protrusion 73 is inserted into the mounting hole 11 on the canopy sheet metal 1.

[0025] The inner wall of the radar outer bracket 2 is partially expanded outward to form a positioning groove 21, and the side wall of the radar sleeve 4 is partially protruded outward to form a positioning protrusion 45. The positioning protrusion 45 and the positioning groove 21 cooperate to achieve the positioning and assembly of the radar sleeve 4 in the radar outer bracket 2.
