Description

BACKGROUND

1. Technical Field

The present disclosure relates to electronic devices, and particularly to an electronic device with a keyboard.

2. Description of Related Art

A supporting structure is generally secured to a bottom portion of a keyboard, especially a keyboard of a notebook, to prevent the keyboard from elastically deforming when the keyboard is tapped. Generally, the supporting structure is a supporting plate made of metal or plastic. However, the supporting plate occupies a substantial volume in the notebook chassis. Therefore, there is room for improvement in the art.

DETAILED DESCRIPTION

The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”

FIG. 1 shows one embodiment of an electronic device. The electronic device comprises a keyboard module 10, a cover 30, and a support beam 50. The electronic device may be notebook computer, for example.

The keyboard module 10 can comprise a keyboard plate 15 and a base plate 12 adhered to a bottom surface of the keyboard plate 15. The keyboard plate 15 comprises a plurality of keycaps 152. The keyboard plate 15 is substantially rectangular and comprises a top edge 155 and a bottom edge 156. The top edge 155 and the bottom edge 156 are two long edges of the keyboard plate 15. The base plate 12 comprises a plurality of touch switches (not shown) corresponding to the plurality of keycaps 152. The keyboard module 10 may be a membrane keyboard module, for example.

The cover 30 defines a keyboard area 31. The keyboard area 31 is substantially rectangular and comprises a frame 32 located in the keyboard area 31.

FIGS. 2 and 5 show that a cross section of the support beam 50 is a curved structure. In one embodiment, the support beam 50 extends straight, and the cross section of the support beam 50 is “U” shaped. The support beam 50 comprises a supporting piece 51 and two flanges 53 extending from opposite edges of the supporting piece 51. A first mounting portion 62 extends from each end of the support beam 50. A plurality of second mounting portions 64 is located between the first mounting portions 62 and extend from the support beam 50 in the opposite direction of the first mounting portions 62.

FIGS. 3-5 show that in assembly, the keyboard module 10 is received in the keyboard area 31. The first mounting portion 62 extends outside of the base board 12. The first mounting portion 62 is secured to the frame 32 by screws or other securing methods. The second mounting portions 64 are secured to the frame 32 through the base board 12. The support beam 50 is substantially parallel to the top edge 155 and the bottom edge 156 of the keyboard plate 15. The supporting piece 51 abuts the base board 12. The flanges 53 extend away from the keyboard module 10. Thus, the support beam 50 supports the keyboard module 10.

In the illustrated embodiment, the installation position of the support beam 50 can be adjusted as required. For example, if the plurality of keyboard caps 152 is adjacent to the bottom edge 156, a distance between the support beam 50 and the bottom edge 156 is smaller than a distance between the support beam 50 and the top edge 155.

In other embodiments, the support beam 50 can be secured to the top edge 155 or the bottom edge 156. The support beam 50 can be slanted relative to the top edge 155 and the bottom edge 156. The support beam 50 can define a curved structure.

FIGS. 6-7 show that in other embodiments, a cross section of the support beam 80, 90 can be other curved structures, such as “L” shaped, “D” shaped, and waved.

The number of the support beams 50 can be two or more to add strength to the keyboard module 10. The two or more supporting beams 50 can be substantially parallel to each other to support the keyboard module 10 cooperatively.

It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and the arrangement of parts within the principles of the disclosure, to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
