An anti-rotation and anti-off mounting structure for an automobile sensor

Abstract

The invention provides a rotation and disconnection preventing mounting structure of a car sensor. The rotation and disconnection preventing mounting structure comprises a front protection anti-collision beam and the car sensor. A flanging hole is formed in the front protection anti-collision beam. The car sensor is provided with at least two clamp feet. The flanging hole comprises a flanging flange. A rotation preventing grooves is formed in the flanging flange. The clamp feet penetrate the flanging hole and connected with the same in a fastening manner. The clamp feet are disposed in the rotation preventing groove. The rotation and disconnection preventing mounting structure has the advantages that the car sensor is prevented from being disconnected by the fastening connection of the flanging hole and the clamp feet, rotation of the car sensor can be prevented by the coordination of the clamp feet and the rotation preventing groove, and the rotation and disconnection preventing mounting structure is few in parts, simple to machine, low in cost, good in stability and good in rotation and disconnection preventing effect.

Description

technical field [0001] The invention relates to an automobile body, in particular to an anti-rotation and anti-off installation structure of an automobile sensor in the automobile body. Background technique [0002] At present, most of the fixing methods of automotive sensors are that the sensor is connected with a plastic bracket or a sheet metal bracket, fixed on the body with bolts and nuts, and the sensor is stopped by the bracket structure, or directly fixed on the sheet metal, and other auxiliary structures are needed for collision avoidance . Its main disadvantages: [0003] 1) Add anti-rotation bracket separately, add parts (sensor mounting bracket) and connectors (bolts, nuts), and increase the cost; [0004] 2) The anti-rotation feature of the part is small, the processing is difficult, and the stability is poor; [0005] 3) Due to the small size of the sensor, the characteristics of the sheet metal surface are affected by stamping, and the anti-rotation effect ...

AI Technical Summary

Problems solved by technology

[0003] 1) Add anti-rotation bracket separately, add parts (sensor mounting bracket) and connectors (bolts, nuts), and increase the cost;

[0004] 2) The anti-rotation feature of the part is small, the processing is difficult, and the stability is poor;

[0005] 3) Due to the small size of the sensor, the characteristics of the sheet metal surface are affected by stamping, and the anti-rotation effect is prone to failure, resulting in the loose connection between the sensor and the wiring harness and functional failure;

[0006] 4) There is no anti-rotation structure or anti-rotation failure, resulting in loosening of the sensor harness, and repeated movement is worn through by the sheet metal, resulting in sensor function failure
