Abstract

The technology provides for an electronic device. The electronic device includes a housing, a display cover, and a modular component configured to provide a seal between the housing to the display cover. The modular component is configured to be attached to the housing. Further, the modular component includes a first surface configured to be attached to the display cover. The modular component includes a channel extending along the first surface, where the channel is configured to hold a liquid adhesive that bonds with the display cover. The modular component further includes a radial protrusion disposed on the first surface, the radial protrusion is configured to be in contact with the display cover when the display cover is attached to the housing and to prevent the liquid adhesive from moving out of the channel.

First claim

The invention claimed is:

1. An electronic device, comprising:
a housing;
a display cover;
a modular component configured to be attached to the housing and to provide a seal between the housing and the display cover, the modular component including:
a first surface configured to be attached to the display cover;
a channel extending along the first surface, the channel configured to hold a liquid adhesive that bonds with the display cover;
a radial protrusion disposed on the first surface, the radial protrusion configured to be in contact with the display cover when the display cover is attached to the housing and to prevent the liquid adhesive from moving out of the channel.

2. The electronic device of claim 1 , wherein the modular component further includes one or more antennas.

3. The electronic device of claim 2 , wherein the one or more antennas are disposed on the first surface, and the radial protrusion is disposed between the one or more antennas and the channel such that the radial protrusion prevents the liquid adhesive from moving to the one or more antennas.

4. The electronic device of claim 2 , wherein the radial protrusion is configured to provide a predetermined clearance distance between the one or more antennas and the display cover.

5. The electronic device of claim 2 , wherein the modular component is configured to provide a predetermined clearance distance between the one or more antennas and the housing.

6. The electronic device of claim 1 , wherein the display cover has a three-dimensional shape with one or more curved portions, wherein the channel is positioned such that the liquid adhesive bonds with the one or more curved portions of the display cover, and wherein the radial protrusion is configured to be in contact with the one or more curved portions of the display cover.

7. The electronic device of claim 1 , wherein the display cover has one or more viewing regions with a display underneath and one or more peripheral regions configured to be attached to the housing, wherein the channel is positioned so that the liquid adhesive bonds with the one or more peripheral regions, and wherein the radial protrusion is configured to be in contact with the one or more peripheral regions such that the radial protrusion prevents the liquid adhesive from moving to the one or more viewing regions.

8. The electronic device of claim 1 , wherein the radial protrusion is configured to have dimensions matching at least a portion of an inside surface of the display cover.

9. The electronic device of claim 1 , wherein the modular component has an arcuate shape configured to fit along a portion of an edge of the housing.

10. The electronic device of claim 1 , wherein the modular component has a ring shape configured to fit along an entire edge of the housing.

11. The electronic device of claim 1 , wherein an edge of the housing configured to be in contact with the display cover includes an indent providing additional space for holding the liquid adhesive.

12. The electronic device of claim 1 , wherein the housing is made of a conductive material, and the display cover is made of a dielectric material.

13. A modular component for sealing a display cover to a housing of an electronic device, the modular component configured to be attached to the housing, the modular component comprising:
a first surface configured to be attached to the display cover;
a channel extending along the first surface, the channel configured to hold a liquid adhesive that bonds with the display cover;
a radial protrusion disposed on the first surface, the radial protrusion configured to be in contact with the display cover when the display cover is attached to the housing and to prevent the liquid adhesive from moving out of the channel.

14. The modular component of claim 13 , further comprising:
one or more antennas.

15. The modular component of claim 14 , wherein the one or more antennas is disposed on the first surface, and the radial protrusion is disposed between the one or more antennas and the channel.

16. The modular component of claim 13 , wherein the modular component has an arcuate shape configured to fit along a portion of an edge of the housing.

17. The electronic device of claim 13 , wherein the modular component has a ring shape configured to fit along an entire edge of the housing.

18. An antenna carrier for an electronic device, the antenna carrier comprising:
a first surface, the first surface having a first area configured to be attached to an inside surface of a housing of the electronic device;
a channel extending along the first surface in the first area, the channel configured to hold a liquid adhesive that bonds with the inside surface of the housing;
one or more antennas disposed in a second area on the first surface;
a radial protrusion disposed on the first surface in the first area between the channel and the one or more antennas, the radial protrusion configured to be in contact with the inside surface of the housing to prevent the liquid adhesive from moving out of the channel to the one or more antennas.

19. The antenna carrier of claim 18 , wherein the one or more antennas are disposed on the first surface by laser direct structuring (LDS).

20. The antenna carrier of claim 18 , wherein the one or more antennas includes a plurality of antennas configured to operate in different frequency ranges.
