Abstract

A vehicle front end structure includes a bumper fascia, a headlamp assembly and a front grille. The bumper fascia has a main body and a projecting portion extending upwardly from the main body. An inboard side of the projecting portion includes a flange. The headlamp assembly includes a housing installed to the bumper fascia above the main body via a projection extending in an inboard direction from an inboard side of the housing. The projection includes an attachment part releasably fastened to the flange. The front grille is installed to the bumper fascia above the main body and inboard of the projecting portion of the bumper fascia. The front grille also attaches to the flange such that the projecting portion of the bumper fascia extends between an outboard edge of the front grille and an inboard side of the lens.

First claim

What is claimed is:

1. A vehicle front end structure comprising
a bumper fascia having a main body and a projecting portion, the projecting portion extending upwardly from the main body and having an inboard side and an outboard side, the inboard side including a flange with a first attachment part and a second attachment part, the first attachment part of the flange of the projecting portion includes a controlled deformation zone such that in response to a low speed impact event areas of the first attachment part adjacent to the controlled deformation zone deform;
a headlamp assembly having a housing and a lens attached to the housing, the housing being installed to the bumper fascia above the main body and including a projection that extends in an inboard direction from an inboard side of the housing along a rearward surface of the flange of the projecting portion of the bumper fascia, the projection including a third attachment part that is releasably fastened to the first attachment part of the bumper fascia; and
a front grille installed to the bumper fascia above the main body and having a fourth attachment part releasably fastened to the second attachment part of the flange, the front grille covering the first attachment part and the third attachment part of the flange of the projecting portion, the projecting portion of the bumper fascia extending between an outboard edge the front grille and an inboard side of the lens such that the main body, the projecting portion, an outer surface of the lens and an outer surface of the front grille define a contoured outer front surface of a vehicle.

2. The vehicle front end structure according to claim 1 , wherein
the controlled deformation zone is defined by a slot in a portion of flange adjacent to the first attachment part, the slot extending from an inboard surface of the flange to an outboard surface of the flange.

3. The vehicle front end structure according to claim 2 , wherein
the slot extends in a horizontal direction.

4. The vehicle front end structure according to claim 2 , wherein
the slot extends in a vertical direction.

5. A vehicle front end structure comprising
a bumper fascia having a main body and a projecting portion, the projecting portion extending upwardly from the main body and having an inboard side and an outboard side, the inboard side including a flange with a first attachment part and a second attachment part;
a headlamp assembly having a housing and a lens attached to the housing, the housing being installed to the bumper fascia above the main body and including a projection that extends in an inboard direction from an inboard side of the housing along a rearward surface of the flange of the projecting portion of the bumper fascia, the projection including a third attachment part that is releasably fastened to the first attachment part of the bumper fascia; and
a front grille installed to the bumper fascia above the main body and having a fourth attachment part releasably fastened to the second attachment part of the flange, the front grille covering the first attachment part and the third attachment part of the flange of the projecting portion, the projecting portion of the bumper fascia extending between an outboard edge the front grille and an inboard side of the lens such that the main body, the projecting portion, an outer surface of the lens and an outer surface of the front grille define a contoured outer front surface of a vehicle,
the flange of the projecting portion of the bumper fascia includes a doghouse structure with the first attachment part being defined by a fastener receiving opening that extends from a recessed surface of the doghouse to the rearward surface of the flange.

6. The vehicle front end structure according to claim 5 , wherein
the doghouse structure includes a controlled deformation zone adjacent to the first attachment part such that in response to a low speed impact event areas of the doghouse structure adjacent to the controlled deformation zone deform.

7. The vehicle front end structure according to claim 6 , wherein
the controlled deformation zone is defined by a slot in a portion of the doghouse structure adjacent to the first attachment part, the slot extending from an inboard surface of the doghouse structure to an outboard surface of the doghouse structure.

8. The vehicle front end structure according to claim 7 , wherein
the slot extends in a horizontal direction.

9. The vehicle front end structure according to claim 7 , wherein
the slot extends in a vertical direction.

10. The vehicle front end structure according to claim 5 , wherein
the doghouse structure includes:
an upright surface that extends rearward from a forward facing surface of the flange,
a lower surface that extends rearward from the forward facing surface of the flange and extends in an outboard direction from the upright surface, and
the recessed surface, the recessed surface being perpendicular to the upright surface and extending from the upright surface to the lower surface.

11. The vehicle front end structure according to claim 10 , wherein
the doghouse structure includes a controlled deformation zone located in an area corresponding to a convergence of the upright surface, the lower surface and the recessed surface.

12. The vehicle front end structure according to claim 11 , wherein
the controlled deformation zone is defined by a slot that extends from a first side of the doghouse structure to a second side of the doghouse structure in the area corresponding to the convergence of the upright surface, the lower surface and the recessed surface.

13. The vehicle front end structure according to claim 5 , wherein
the outboard edge of the front grille and an upper inboard edge of the lens extend alongside one another above the projecting portion of the bumper fascia.

14. The vehicle front end structure according to claim 13 , wherein
the outboard edge of the front grille overlays a section of the lens adjacent to the upper inboard edge of the lens above the projecting portion of the bumper fascia.

15. The vehicle front end structure according to claim 14 , wherein
the lens of the headlamp assembly has a lower inboard edge that extends upward that intersects with the upper inboard edge of the lens defining tapered inboard end, and
the projecting portion of the bumper fascia has an upwardly extending inboard edge and an upwardly extending outboard edge that define an upper tapered end located adjacent to the tapered inboard end of the lens and the front grill.

16. The vehicle front end structure according to claim 15 , wherein
the first attachment part of the flange of the projecting portion includes a controlled deformation zone such that in response to a low speed impact event areas of the first attachment part adjacent to the controlled deformation zone deform.

17. The vehicle front end structure according to claim 16 , wherein
the controlled deformation zone is defined by slot in a portion of the flange adjacent to the first attachment part, the slot extending from a first surface of the attachment flange to a second surface of the attachment flange.

18. The vehicle front end structure according to claim 13 , wherein
the outboard edge of the front grille further extends cornerlessly from the upper inboard edge of the lens along the inboard side of the projecting portion of the bumper fascia.

19. A vehicle front end structure comprising
a bumper fascia having a main body and a projecting portion, the projecting
