Specifically, the detection portion of the sensor assembly 30 is located at the detection end 102, the detection end 102 faces the vehicle body outside, and the housing 10 is inserted into the mounting hole from the insertion end 101. The first guide edge 221 is a side edge connected to the connecting portion 21, and the first guide edge 221 is gradually inclined in a direction away from the insertion end 101 in a direction away from the connecting portion 21. It can be understood that, when the housing 10 is inserted into the mounting hole, the first guiding edge 221 abuts against the edge of the mounting hole on the outer surface of the bumper, and in the process of inserting the housing 10 into the mounting hole, the first guiding edge 221 has a guiding function, so that the elastic portion 22 can be gradually elastically pressed towards the outer surface of the housing 10 when the hole edge of the mounting hole is extruded, and thus, the mounting of the reversing radar 100 is facilitated.
