Abstract

An electronic mobile device includes a device housing and a spacer supported within the device housing. An outer panel is supported by the spacer, and the outer panel and the spacer together define an internal recess. A display configured to display information is supported by the device housing within the internal recess. A gasket is compressed between the device housing, the spacer, and the outer panel to inhibit debris ingress to the device housing. The gasket has a first side that engages the device housing and a second side that engages the spacer and the outer panel.

Claims

1. An electronic mobile device, comprising:

a device housing;

a spacer supported within the device housing;

an outer panel supported by the spacer, the outer panel and the spacer together defining an internal recess;

a display configured to display information and being supported by the device housing within the internal recess;

a gasket compressed between the device housing, the spacer, and the outer panel to inhibit debris ingress to the device housing, the gasket having a first side engaging the device housing and a second side engaging the spacer and the outer panel; and

wherein the gasket presses against the outer panel more loosely than it does against the spacer, the second side has a surface area, and the spacer engages at least two-thirds of the surface area and the outer panel engages at most one-third of the surface area.

2. The electronic mobile device of claim 1, wherein the spacer and the display define a gap there between to inhibit forces from being transferred from the spacer directly to the display.

3. The electronic mobile device of claim 1, wherein the gasket has a rectangular cross-sectional shape with two arcuate corners.

4. The electronic mobile device of claim 3, wherein the two arcuate corners engage the device housing.

5. The electronic mobile device of claim 1, wherein the gasket comprises an elastically-deformable polymer.

6. The electronic mobile device of claim 1, wherein the gasket is compressed against an outer perimeter of the outer panel.

7. An electronic mobile device, comprising:

a device housing including;

a back wall;

a plurality of side walls adjacent the back wall, the plurality of side walls defining a front recess opposite the back wall;

a display assembly disposed within the front recess and including;

a display configured to display information and having an outer perimeter;

a spacer extending about the outer perimeter;

an outer panel overlaying the display and the spacer;

a gasket having a first side abutting the plurality of side walls and a second side abutting the spacer and the outer panel to inhibit debris ingress to the device housing; and

wherein the gasket presses against the outer panel more loosely than it does against the spacer, the second side has a surface area, and the spacer engages at least two-thirds of the surface area and the outer panel engages at most one-third of the surface area.

8. The electronic mobile device of claim 7, wherein the spacer and the display define a gap there between to inhibit forces from being transferred from the spacer directly to the display.

9. The electronic mobile device of claim 7, wherein the display assembly further comprises a display base supporting the display and the spacer.

10. The electronic mobile device of claim 7, wherein the outer panel is a touch-sensitive panel.

11. The electronic mobile device of claim 7, wherein the plurality of side walls defines a gasket channel in which the first side of the gasket is disposed.

12. A method of manufacturing an electronic mobile device, comprising the steps of:

providing a display base;

connecting a spacer to the display base such that the spacer and the display base together define an internal recess;

positioning a gasket about an outer perimeter of the spacer opposite the internal recess;

positioning a display within the internal recess;

positioning an outer panel proximate the display and the spacer and outside of the internal recess such that an outer perimeter of the outer panel is spaced apart from the gasket; and

deforming the gasket such that the gasket engages the outer perimeter of the outer panel.

13. The method of claim 12, wherein the step of deforming the gasket such that the gasket engages the outer perimeter of the outer panel includes engaging a side of the gasket opposite the outer panel with a plurality of side walls of a device housing.

14. The method of claim 13, wherein the step of engaging the gasket with the plurality of side walls of the device housing includes positioning the gasket within a gasket channel defined by the plurality of side walls.

15. The method of claim 12, wherein the step of positioning the display within the internal recess includes positioning the display such that an outer perimeter of the display is spaced apart from the spacer.

16. The method of claim 12, wherein the step of connecting the gasket about the outer perimeter of the spacer includes co-molding the gasket to the spacer.

17. The method of claim 12, wherein the step of connecting the spacer to the display base includes insert molding the spacer to the display base.

18. The method of claim 12, further comprising the step of connecting a first adhesive to the display base within the internal recess, and wherein the step of positioning the display within the internal recess includes connecting the display to the first adhesive opposite the display base.

19. The method of claim 18, further comprising the step of connecting a second adhesive to the display opposite the display base, and wherein the step of positioning the outer panel proximate the display includes connecting the outer panel to the second adhesive opposite the display.
