Embodiment

In order to make feature of the present utility model more clear, below will disclose the various embodiment of the utility model.

Please refer to Fig. 2 and illustrate STRUCTURE DECOMPOSITION schematic diagram according to one preferred embodiment of the utility model keyboard sidelight structure, the keyboard sidelight structure of present embodiment comprises key groups 10, light guide plate 20 and luminescence component 30, wherein light guide plate 20 can be single plate body or is made of the plural pieces plate body, in the present embodiment as an illustration with single plate body, as shown in the figure, each light guide plate 20 is disposed at key groups 10 belows, luminescence component 30 then is set in parallel in a side of each light guide plate 20, in more detail, one side of each light guide plate 20 is an incidence surface 201, and luminescence component 30 is the enforcement means with the light-emitting diode in present embodiment, certainly it only is a kind of execution mode of the utility model luminescence component 30, its luminescence component 30 regards to each incidence surface 201 and is provided with, and parallel with each light guide plate 20, that is in the same plane, by this, the light that luminescence component 30 is sent is injected in each light guide plate 20 via the incidence surface 201 of each light guide plate 20, is penetrated by the front of each light guide plate 20 again.

For the integral body that more clearly demonstrates the utility model keyboard sidelight structure is formed, see also Fig. 3 and shown in Figure 4, key groups 10 includes a base plate 11, one film circuit board 12, a transparent membrane 13 and a button 14, wherein, has a hole 111 on the base plate 11, and also has a filling member 112 in the hole 111, and film circuit board 12 is arranged on the base plate 11, transparent membrane 13 is arranged on the film circuit board 12 again, button 14 is arranged on the transparent membrane 13 again, and utilize bridge formation 15 to be installed on the base plate 11, and it is corresponding with hole 111 positions, filling member 112 and button 14 are positioned on the same vertical line, and in addition, filling member 112 is constituted by transparent material, by this, after the light of luminescence component 30 penetrates via light guide plate 20, penetrable filling member 112, film circuit board 12, the user can be convenient to look from outside the sight for transparent membrane 13 and the button 14 that arrives.

In addition, in another embodiment of the present utility model, as shown in Figure 5,10 of its key groups include base plate 11, a film circuit board 12, transparent membrane 13 and a button 14 of a transparent material, because the base plate 11 of transparent material itself promptly has light peneration, so need not to be provided with hole, light just can directly penetrate the base plate 11, film circuit board 12, transparent membrane 13 of transparent material and the user can be convenient to look from outside the sight for the button 14 that arrives again.

In addition, each light guide plate can set up a reflector plate 206 ' (as shown in Figures 2 and 3) 20 times in the present embodiment, or as shown in Figure 4, be formed with a catoptric arrangement 206 in the bottom surface of light guide plate 20, be used for reflection ray, make the light extraction efficiency of each light guide plate 20 better, and catoptric arrangement 206 can be formed at the back side of light guide plate 20 with printing or integrated mode, or utilizing a reflector plate to be attached at light guide plate 20 back sides also can.

The 6th to Fig. 9, be used for explanation at each embodiment of the present utility model, the configuration aspect of its luminescence component 30, as shown in Figure 6, with a luminescence component 30 configured in parallel in a side of each light guide plate 20, or can be as shown in Figure 7, for making light extraction efficiency higher, configurable a plurality of luminescence component 30, and configured in parallel is in the two sides of each light guide plate 20, and relative two sides of light guide plate 20 have also formed incidence surface 201 respectively, each luminescence component 30 promptly respectively with incidence surface 201 corresponding settings, also can be as shown in Figure 8, each luminescence component 30 configured in parallel is the side around each light guide plate 20, certainly, more can be as shown in Figure 9, be provided with more than one hole 202 in light guide plate 20, then wall then is an incidence surface 201 around the hole 202, luminescence component 30 is set in parallel in 202 of each holes of this light guide plate 20, light is injected in each light guide plate 20 via the incidence surface 201 of 202 of each light guide plate 20 each holes, penetrate by the front of each light guide plate 20 again, they are different with the mode that luminescence component 30 is arranged at light guide plate 20 belows with tradition, because luminescence component 30 is positioned on the same horizontal plane with each light guide plate 20 in the present embodiment, so the thickness that the integral body of keyboard sidelight structure is formed in the present embodiment is littler, when it is applied on the Keysheet module, the integral thickness of Keysheet module is reduced, to reach the purpose of thin typeization.

What deserves to be mentioned is, as shown in Figures 3 and 4, luminescence component 30 comprises a circuit board 31 independently, in other words, this circuit board 31 only provides luminescence component 30 to use, please refer to Fig. 2 simultaneously, the film circuit board 12 of key groups 10 utilizes an independent power supply line 16 to provide key groups 10 power supplys to use, and the circuit board 31 of luminescence component 30 also utilizes an independent power supply line 32 thus, luminescence component 30 can make the operation usefulness and the luminous efficacy of key groups 10 and luminescence component 30 better because of not needing to share one group of power supply supply with key groups 10.

Be with, keyboard sidelight structure provided by the utility model the most important thing is to make Keysheet module to reach whole purpose of thinness, is arranged at the design of light guide plate side by luminescence component, reaches the requirement that reduces keyboard sidelight structural entity thickness.Therefore the utility model has novelty and progressive, and fills and part meet the important document of applying for utility model patent, so file an application in accordance with the law, prays an ancient unit of weight office and grants quasi patent early, and the true feeling moral just.

Below the utility model is done one and describe in detail, however above-described, only be preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented.Be that all equalizations of doing according to the utility model application range change and modify etc., all should still belong in the patent covering scope of the present utility model.
