Abstract

An electronic device includes at least one electronic component. The electronic device also includes a first housing of a single piece of metal. The first housing defines a length, a width, and a height that is less than both the length and the width. The housing has at least five side walls defining an internal cavity and an open end to the cavity that spans the width and height of the first housing. The electronic component is contained within the cavity. A cover is removably affixed over the open end of the housing so as to contribute to a retaining force applied on the electronic component therein. The first housing can be a base housing for a portable computer, and the cover can be a first portion of a hinge assembly. The electronic device can further include a display assembly operatively connected to the base housing by the hinge assembly.

Claims

1. An electronic device, comprising:

at least one electronic component;

a first housing of a single piece of material, the first housing defining a length, a width, and a height that is less than both the length and the width, the first housing having at least five side walls defining an internal cavity and an open end to the cavity that spans the width and height of the first housing, the electronic component being contained within the cavity; and

a cover removably affixed over the open end of the first housing so as to contribute to a retaining force applied on the electronic component therein.

2. The device of claim 1, wherein the single piece of material is a single piece of metal.

3. The device of claim 1, wherein the first housing is a base housing for a base assembly of a portable computer, and wherein the cover is a first portion of a hinge assembly, the electronic device further including a lid assembly operatively connected to the base housing by the hinge assembly.

4. The device of claim 3, wherein the lid assembly includes a lid housing substantially of a single piece of material and having at least five side walls defining an internal cavity and an open end thereto, the lid assembly further including a display unit received within the cavity of the lid housing, and wherein the hinge assembly includes a second portion removably affixed over the open end of the display housing.

5. The device of claim 1, wherein the first housing is a lid housing for a lid assembly of a portable computer, and wherein the cover is a first portion of a hinge assembly, the device further including a base assembly operatively connected to the lid assembly by the hinge assembly.

6. The device of claim 1, wherein at least one of the side walls of the first housing includes an opening to expose a portion of the electronic component.

7. The device of claim 6, wherein the electronic component is a trackpad assembly including a touch-sensitive surface, and wherein the touch-sensitive surface is exposed within the opening.

8. The device of claim 6, wherein the electronic component is a keyboard assembly including a plurality of keys, and wherein at least the keys of the keyboard assembly are exposed within the opening.

9. The device of claim 6, wherein the electronic component includes at least one external connection element, and wherein the at least one external connection element is exposed within the opening.

10. The device of claim 1, wherein the electronic element is positioned within a space defined between two spaced apart and parallel ones of the side walls, the electronic device further including a shim member wedged between the electronic component a first one of the two side walls and forcing at least a portion of the electronic element against a second one of the two side walls.

11. The device of claim 10, wherein the shim member is a portion of a second electronic component received within the internal cavity of the housing.

12. The device of claim 1, wherein at least one of the side walls includes a hole therethrough, and wherein the electronic component includes a threaded hole therein aligned with the hole in the side wall, the electronic device further including a screw passing through the hole in the first housing and engaging with the threaded hole of the electronic component.

13. The device of claim 1, wherein the electronic component is an assembly of a printed circuit board and one or more support units configured to contact at least two of the side walls of the housing within the internal cavity, the one or more support units being assembled with the printed circuit board to retain the printed circuit board within the housing and spaced apart from the side walls.

14. The device of claim 1, wherein the electronic component is one of a plurality of electronic components within the housing, at least some of the electronic components contacting at least one of the side walls, respectively, and the at least some of the electronic components contacting each other along respective portions thereof to help retain the at least some of the electronic components in predetermined positions within the housing.

15. The device of claim 1, wherein the cover exerts a retention force on the electronic component to help retain the electronic component in a predetermined position within the housing.
