Abstract

An elastically averaging alignment and retention system for a sealable compartment includes a first component and a second component. The first component includes a first alignment member and an elastically deformable alignment element fixedly disposed with respect to the first alignment member, the elastically deformable alignment element having an elongated hollow tube. The second component includes a second alignment member and an alignment feature fixedly disposed with respect to the second alignment member, the alignment feature having a blind-end pocket. The elastically deformable alignment element is configured and disposed to interferingly, deformably and matingly engage the alignment feature. Portions of the elastically deformable alignment element when inserted into the alignment feature elastically deform to an elastically averaged final configuration that aligns the first component relative to the second component in at least two of four planar orthogonal directions.

First claim

What is claimed is:

1. An elastically averaging alignment and retention system for a sealable compartment, comprising:
a first component comprising a first alignment member and an elastically deformable alignment element fixedly disposed with respect to the first alignment member, the elastically deformable alignment element comprising an elongated elastically deformable alignment element;
a second component comprising a second alignment member and an alignment feature fixedly disposed with respect to the second alignment member, the alignment feature comprising a closed alignment feature;
wherein the elastically deformable alignment element is configured and disposed to interferingly, deformably and matingly engage the alignment feature; and
wherein portions of the elastically deformable alignment element when inserted into the alignment feature elastically deform to an elastically averaged final configuration that aligns the first component relative to the second component in at least two of four planar orthogonal directions.

2. The elastically averaging alignment and retention system of claim 1 , wherein:
the elongated elastically deformable alignment element comprises a hollow tube; and
the closed alignment feature comprises a blind-end pocket.

3. The elastically averaging alignment and retention system of claim 1 , further comprising:
a third component sealingly engagable with the second component to form the sealable compartment, the first component being disposed between the second and third components and within the sealable compartment.

4. The elastically averaging alignment and retention system of claim 2 , wherein:
the hollow tube comprises a retention element configured and disposed to engage with the pocket.

5. The elastically averaging alignment and retention system of claim 2 , wherein:
the blind-end pocket comprises a retention feature configured and disposed to engage with the elongated elastically deformable alignment element.

6. The elastically averaging alignment and retention system of claim 5 , wherein:
the hollow tube comprises a retention element configured and disposed to engage with the retention feature of the pocket.

7. The elastically averaging alignment and retention system of claim 6 , wherein:
the retention element comprises a latch surface disposed at a distal end of the hollow tube;
the retention feature comprises a catch surface disposed proximate the blind-end of the pocket; and
the latch surface is configured to engage the catch surface.

8. The elastically averaging alignment and retention system of claim 7 , wherein:
the pocket has a completely open-side from an entry-end to the blind-end of the pocket.

9. The elastically averaging alignment and retention system of claim 8 , wherein:
the hollow tube is engagable with the pocket by insertion of the hollow tube into the entry-end of the pocket, and by insertion of the hollow tube into the open-side of the pocket.

10. The elastically averaging alignment and retention system of claim 7 , wherein:
the pocket has an open-side portion proximate the blind-end of the pocket, and has a closed-side portion that completely surrounds the pocket in a region between an entry-end and the open-side portion of the pocket.

11. The elastically averaging alignment and retention system of claim 1 , wherein:
the first component comprises a first, a second, a third and a fourth of the elastically deformable alignment element comprising an elongated hollow tube, the first and second hollow tubes being smaller in diameter than the third and fourth hollow tubes;
the second component comprises a first, a second, a third and a fourth of the alignment feature comprising a blind-end pocket;
each of the first and second pockets have an open-side portion proximate the respective blind-end, and have a closed-side portion that completely surrounds the respective pocket in a region between an entry-end and the open-side portion of the respective pocket;
each of the third and fourth pockets have a completely open-side from an entry-end to the blind-end of the respective pocket;
the first and second hollow tubes are disposed to interferingly, deformably and matingly engage with respective ones of the first and second pockets; and
the third and fourth hollow tubes are disposed to interferingly, deformably and matingly engage with respective ones of the third and fourth pockets.

12. The elastically averaging alignment and retention system of claim 11 , further comprising:
a third component sealingly engagable with the second component to form the sealable compartment, the first component being disposed between the second and third components and within the sealable compartment; and
wherein the third component is movably coupled to the second component via a hinge.

13. The elastically averaging alignment and retention system of claim 3 , wherein:
the third component comprises a lip that surrounds the sealable compartment;
the second component comprises a flange that surrounds the sealable compartment; and
the lip is disposed and configured to sealingly mate with the flange when the first and second components are interferingly, deformably and matingly engaged with each other.

14. The elastically averaging alignment and retention system of claim 3 , wherein:
the first component comprises a first portion of a vehicle;
the second component comprises a second portion of the vehicle; and
the third component comprises a third portion of the vehicle.

15. The elastically averaging alignment and retention system of claim 14 , wherein:
the first portion of the vehicle is a bezel insert of a charge port;
the second portion of the vehicle is a housing of the charge port; and
the third portion of the vehicle is a cover of the charge port.
