Arrangement of a headlamp shell, a sensor and a protective plate for the sensor in a vehicle
View Patent ↗A sensor mounting arrangement for a vehicle has a headlamp shell ( 5 ) with a recess ( 14 ) and a hole ( 16 ) spaced from the recess ( 14 ). A protective plate ( 11 ) has a projection ( 15 ) that protrudes into the recess ( 14 ) of the headlamp shell ( 5 ). A blind rivet bolt ( 18 ) is riveted to the protective plate ( 11 ) at a location spaced from the projection ( 15 ) of the protective plate ( 11 ). The blind rivet bolt ( 18 ) has a bolt head ( 17 ) that passes through the hole ( 16 ) in the headlamp shell ( 5 ). A crash sensor ( 19 ) is connected firmly to the blind rivet bolt ( 18 ) and hence to the protective plate ( 11 ). The connection ensures that forces generated in the event of a crash will not cause the protective plate ( 5 ) to shear off the headlamp shell ( 5 ) before the sensor ( 19 ) has time to respond.
1. A sensor mounting arrangement for a vehicle, comprising:
a headlamp shell formed with a recess and a hole spaced from the recess;
a protective plate engaged with the headlamp shell and having a projection that protrudes into the recess of the headlamp shell;
a blind rivet bolt riveted to the protective plate at a location spaced from the projection of the protective plate, the blind rivet bolt having a shank and a bolt head that passes through the hole in the headlamp shell; and
a sensor connected firmly to the shank of the blind rivet bolt and to the protective plate.
2. The arrangement of claim 1 , wherein the headlamp shell and the protective plate are made of aluminum or an aluminum alloy.
3. The arrangement of claim 1 , wherein the projection of the protective plate is a boss, and the recess of the headlamp shell is a through hole.
4. The arrangement of claim 1 , wherein the headlamp shell is a metal sheet.
5. The arrangement of claim 4 , wherein the protective plate and the headlamp shell are connected together in an area of a substantially flat section of the headlamp shell.
6. The arrangement of claim 5 , wherein the protective plate and the headlamp shell are firmly connected by clinched connections.
7. The arrangement of claim 6 , wherein four clinched connections are provided and are arranged to form a rectangle.
8. The arrangement of claim 7 , wherein the hole in the headlamp shell for the blind rivet bolt is located inside the rectangle and the recess on the headlamp shell is not arranged outside the rectangle.
9. The arrangement of claim 1 , wherein the protective plate is cap-shaped and has a roof section connected to the headlamp shell in an area of a base of the headlamp shell.
10. The arrangement of claim 1 , wherein the shank of the blind rivet bolt is threaded, the arrangement further comprising a nut threaded to the shank for securely connecting the sensor to the protective plate.
11. A sensor mounting arrangement for a vehicle, comprising:
a headlamp shell formed from aluminum or an aluminum alloy and having a recess and a hole spaced from the recess;
a protective plate formed from aluminum or an aluminum alloy and having a projection that protrudes into the recess of the headlamp shell, the protective plate being connected to the headlamp shell at a plurality of spaced apart clinch connections disposed so that the projection is not outside an area bounded by the clinch connections;
a blind rivet bolt riveted to the protective plate at a location spaced from the projection of the protective plate and within the area bounded by the clinch connections, the blind rivet bolt having a threaded shank and a bolt head that passes through the hole in the headlamp shell;
a crash sensor mounted on the threaded shank of the blind rivet bolt; and
a nut threaded on the shank of the blind rivet bolt and securely connecting the crash sensor to the protective plate.
12. The arrangement of claim 11 , wherein the protective plate and the headlamp shell are connected together in an area of a substantially flat section of the headlamp shell.
13. The arrangement of claim 11 , wherein four clinched connections are provided and are arranged to form a rectangle.
14. The arrangement of claim 11 , wherein the protective plate is cap-shaped and has a roof section connected to the headlamp shell in an area of a base of the headlamp shell.
