Embodiment
The utility model is described for reaching employed technological means of purpose and effect hereinafter with reference to the accompanying drawing of enclosing, and the cited embodiment of the following drawings only is an aid illustration, your in order to juror understand, but the technological means of this case is not limited to cited accompanying drawing.
See also Fig. 2 and Fig. 3, it is respectively the three-dimensional exploded view and the end view (wherein for ease of signal, Fig. 3 omits elastomer) of the utility model luminous button structure.The utility model luminous button structure 2 comprises a button assembly 20, a light guide plate 21, and a light source 22.Button assembly 20 comprises a keycap 200; Be arranged at keycap 200 belows and have the base plate 201 of some perforation 2010; A scissor structure 202 that is arranged between this keycap 200 and this base plate 201 and is connected with this base plate 201 with this keycap 200 respectively, this scissor structure 202 is articulated by one first support 202a and one second support 202b and forms, thereby keycap 200 can move up and down with respect to base plate 201 thus; More be provided with a film circuit board 203 on this base plate 201, this film circuit board 203 is provided with contactor 2030; For ease of the switching of contactor 2030, more be provided with an elastomer 204 between this film circuit board 203 and this keycap 200, this elastomer 204 places on this contactor 2030 and passes this scissor structure 202; These base plate 201 belows are provided with light guide plate 21, and light guide plate 21 has some accommodation spaces 210; And this film circuit board 203 is provided with some light sources 22 (for example LED), and these light sources 22 are placed in corresponding accommodation space 210 via these perforation 2010; So, light source 22 just can be positioned at same horizontal level with this light guide plate 21, and then makes the keyboard integral thickness can not increase because having set up light source 22.
