Mounting structure, pipeline structure and vehicle

The utility model relates to a mounting structure, a pipeline structure and a vehicle, which are used for mounting a sensor on a pipeline, and the mounting structure comprises a mounting seat arranged on the pipeline, and a first limiting part and a second limiting part which are arranged on the mounting seat. Wherein the sensor is provided with a detection part inserted into the pipeline, and the sensor rotates around the axis of the detection part and can enter the assembly position. Moreover, at the assembly position, the first limiting part and the sensor form limiting fit and limit the rotation of the sensor around the axis of the detection part, and the second limiting part limits the sensor on the mounting seat along the insertion direction of the detection part. According to the installation structure, the sensor can enter the assembly position by rotating around the axis of the detection part, and the sensor can be firmly located at the assembly position by arranging the first limiting part and the s
