DETAILED DESCRIPTION OF THE EMBODIMENTS

The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. This present disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.
Certain terms are used throughout the description and following claims to refer to particular components. As one skilled in the art will appreciate, manufacturers may refer to a component by different names. This document does not intend to distinguish between components that differ in name but function. In the following description and in the claims, the terms “include/including” and “comprise/comprising” are used in an open-ended fashion, and thus should be interpreted as “including but not limited to”. “Substantial/substantially” means, within an acceptable error range, the person skilled in the art may solve the technical problem in a certain error range to achieve the basic technical effect.
The following description is of the best-contemplated mode of carrying out the disclosure. This description is made for the purpose of illustration of the general principles of the disclosure and should not be taken in a limiting sense. The scope of the disclosure is best determined by reference to the appended claims.
Moreover, the terms “include”, “contain”, and any variation thereof are intended to cover a non-exclusive inclusion. Therefore, a process, method, object, or device that includes a series of elements not only includes these elements, but also includes other elements not specified expressly, or may include inherent elements of the process, method, object, or device. If no more limitations are made, an element limited by “include a/an” does not exclude other same elements existing in the process, the method, the article, or the device which includes the element.
In the following embodiment, the same reference numerals are used to refer to the same or similar elements throughout the disclosure.
FIG. 1 and FIG. 2 are schematic diagram and cross-sectional view of an input device of one embodiment of the present disclosure. The input device 1 of this embodiment includes a housing 10, a keyboard assembly 20, and a first light source 30. The housing 10 comprises a body 11 and a plurality of sidewalls 12. The body 11 is opaque, which can be made of opaque material or can be coated with an opaque layer to a surface thereon. The plurality of side walls 12 is transparent. In one embodiment, the surface of the plurality of sidewalls 12 is coated with a translucent layer, such as a translucent layer having a color similar to the color of the body 11, maintaining consistency from the appearance for the housing 10. However, whether the surface of the plurality of sidewalls 12 needs to be coated with a translucent layer and whether the color of the translucent layer needs to be changed according to the actual situation, which is not limited by the present disclosure.
In this embodiment, the plurality of sidewalls 12 is connected to the body 11. The plurality of sidewalls 12 is disposed along the body 11 and extends downward to form an accommodating space 13. It should be noted that the plurality of sidewalls 12 and the body 11 could be integrally formed into one piece, for example, manufactured by double injection molding, or could be connected by other methods such as pasting and riveting after they have been individually molded, but the connecting methods are not limited thereto. The keyboard assembly 20 is disposed in the accommodating space 13, which means the body 11 and the plurality of sidewalls 12 is disposed along the periphery of the keyboard assembly 20. The first light source 30 is disposed below the body 11. The “below” means that the first light source 30 is lower than the body 11 in vertical height, and the present disclosure would not limit any overlapping between the first light source 30 and the body 11 in vertical projection. The first light source 30 comprises a first light emitting element 31 and a first light source circuit board 32. The first light emitting element 31 is disposed on the first light source circuit board 32. Since the plurality of sidewalls, 12 is transparent, the light emitted from the first light emitting element 31 can be emitted from the plurality of sidewalls 12, thereby lighting up the periphery of the keyboard assembly 20.
In one embodiment, the input device 1 further comprises a controller (not shown in) connected to the first light emitting element 31 for activating and deactivating the first light emitting element 31. The electronic device can also have the lighting effects of the first light emitting component 31 corresponding to the using modes of the electronic device, to facilitate the discrimination of the current mode or the electronic device. For example, when the first light emitting element 31 is turned on, that is, the light is coming out from the plurality of sidewalls 12, the electronic device is under a state of e-competition; when the first light emitting element 31 is turned off, that is, the light is not coming out from the plurality of sidewalls 12, the electronic device is under a state of sleep. In this way, the current mode or state of the electronic device can be simply discriminated according to the light emitting state of the plurality of sidewalls 12.
In one embodiment, the keyboard assembly 20 comprises a baseplate 21 and a plurality of keyswitches 22 disposed on the baseplate 21. The plurality of sidewalls 12 extends from the joint between the body 11 toward the baseplate 21. In this embodiment, the angle between the plurality of sidewalls 12 and the body 11 is an obtuse angle. In other embodiments, the angle between the plurality of sidewalls 12 and the body 11 may also be an acute angle or a right angle, which is changeable according to actual requirements, and it is not limited by the present disclosure.
In one embodiment, the input device 1 further comprises an outer frame 40 which is disposed in the accommodating space 13 and is sleeved on the keyboard assembly 20. The outer frame 40 is provided with a plurality of openings 41 adapted to the plurality of keyswitches 22. The plurality of keyswitches 22 protrudes from the plurality of openings 41. The outer frame 40 can protect and position the plurality of keyswitches 22. In addition, the height of the outer frame 40 is lower than that of the body 11. That is, a height difference exists between the outer frame 40 and the body 11, which prevents the outer frame 40 from blocking light coming out from the plurality of sidewalls 12.

As shown in FIG. 4, this embodiment describes the light emitting state of one of the plurality of second light emitting elements 25 disposed on the side of the second light guide plate 27 in a cross-sectional view. The light from the second light emitting element 25 diffuses when passing through the second light guiding plate 27 and is emitted to the plurality of keyswitches 22. It should be noted that the second light guide plate 27 may be provided with a reflective layer and/or a light shielding layer according to the requirements to improve the luminous efficiency, but it is not limited by the present disclosure.
