Abstract

A radar support structure includes a vehicle body structure, an emblem, a radar attachment assembly and a radar unit. The vehicle body structure has a front end, with the emblem being attached to the front end of the vehicle body structure. The radar attachment assembly has an attachment portion, a mounting portion and an energy absorbing portion. The energy absorbing portion is disposed between the attachment portion and the mounting portion. The attachment portion is fixedly attached to the front end of the vehicle body structure. The radar unit is installed to the mounting portion such that the radar unit is spaced apart from and aligned with the emblem.

First claim

What is claimed is:

1. A radar support structure, comprising:
a vehicle body structure having a front end;
an emblem attached to the front end of the vehicle body structure;
a radar attachment assembly having an attachment portion, a mounting portion and an energy absorbing portion disposed between the attachment portion and the mounting portion, the attachment portion being fixedly attached to the front end of the vehicle body structure; and
a radar unit installed to the mounting portion such that the radar unit is spaced apart from and aligned with the emblem.

2. The radar support structure according to claim 1 , wherein
the front end of the vehicle body structure includes a front bumper assembly having a support bracket, an energy absorbing member, a facia member and a grill portion attached to forward portions of a vehicle, the support bracket having a surface spaced apart from the energy absorbing member.

3. The radar support structure according to claim 2 , wherein
the surface of the support bracket is an upper surface thereof.

4. The radar support structure according to claim 3 , wherein
the upper surface of the support bracket is a horizontal surface that extends in a vehicle lateral direction.

5. The radar support structure according to claim 4 , wherein
the attachment portion of the radar attachment assembly is supported by the upper surface of the support bracket of the front bumper assembly.

6. The radar support structure according to claim 1 , wherein
the energy absorbing portion of the radar attachment assembly includes a plurality of fasteners that extend through respective openings is the attachment portion and the mounting portion with a corresponding plurality of spring members being retained between the attachment portion and the mounting portion by corresponding ones of the plurality of fasteners such that in response to impacting forces acting on a forward surface of the radar unit, the plurality of spring members are compressed absorbing at least a portion of the impacting forces.

7. The radar support structure according to claim 3 , wherein
the attachment portion of the radar attachment assembly includes an elongated section and a plate section such that the plate section is supported by the upper surface of the support bracket of the front bumper assembly, and the elongated section is dimensioned and shaped to flex in response to impacting forces acting on a forward surface of the radar unit.

8. The radar support structure according to claim 1 , wherein
the emblem is made of a non-interfering material configured to allow radar signals to pass therethrough.

9. The radar support structure according to claim 8 , wherein
the radar unit is positioned and aligned with the emblem such that radar signals from the radar unit pass through the emblem and radar signals reflected from nearby objects back to the front end of the vehicle body structure pass through the emblem to the radar unit.

10. The radar support structure according to claim 1 , wherein
the emblem includes a vehicle manufacturer's logo.

11. A radar support structure, comprising:
a front bumper assembly having a support bracket, an energy absorbing member and a facia member and attached to forward portions of a vehicle, the support bracket having a surface spaced apart from the energy absorbing member;
a radar attachment assembly having an attachment portion, a mounting portion and an energy absorbing portion disposed between the attachment portion and the mounting portion, the attachment portion being fixedly attached to the surface of the support bracket of the front bumper assembly; and
a radar unit installed to the mounting portion.

12. The radar support structure according to claim 11 , wherein
the surface of the support bracket is an upper surface thereof.

13. The radar support structure according to claim 12 , wherein
the upper surface of the support bracket is a horizontal surface that extends in a vehicle lateral direction.

14. The radar support structure according to claim 13 , wherein
the attachment portion of the radar attachment assembly is supported by the upper surface of the support bracket of the front bumper assembly.

15. The radar support structure according to claim 11 , wherein
the energy absorbing portion of the radar attachment assembly includes a plurality of fasteners that extend through respective openings is the attachment portion and the mounting portion with a corresponding plurality of spring members being retained between the attachment portion and the mounting portion by corresponding ones of the plurality of fasteners such that in response to impacting forces acting on a forward surface of the radar unit, the plurality of spring members are compressed absorbing at least a portion of the impacting forces.

16. The radar support structure according to claim 11 , wherein
the attachment portion of the radar attachment assembly includes an elongated section and a plate section such that the plate section is installed to the upper surface of the support bracket of the front bumper assembly, and the elongated section is dimensioned and shaped to flex in response to impacting forces acting on a forward surface of the radar unit.

17. The radar support structure according to claim 11 , wherein
the front bumper assembly further includes a grill portion attached to the facia member, and an emblem attached to the grill.

18. The radar support structure according to claim 17 , wherein
the emblem is made of a non-interfering material configured to allow radar signals to pass therethrough.

19. The radar support structure according to claim 18 , wherein
the radar unit is positioned and aligned with the emblem such that radar signals from the radar unit pass through the emblem and radar signals reflected from nearby objects back to the front end of the vehicle body structure pass through the emblem to the radar unit.

20. The radar support structure according to claim 18 , wherein
the emblem includes a vehicle manufacturer's logo.
