Below in conjunction with the drawings and specific embodiments, describe the present invention, but not as a limitation of the invention.
Accompanying drawing explanation
Fig. 1 is the generalized section of the button of prior art;
The schematic perspective view that Fig. 2 is the keyboard that proposes according to one embodiment of the invention;
Fig. 3 is that button in Fig. 2 is along the generalized section of X-X hatching.
Embodiment
Refer to Fig. 2, the schematic perspective view that Fig. 2 is the keyboard 2 that proposes according to one embodiment of the invention.As shown in Figure 2, keyboard 2 comprises base plate 30, circuit board 32 and a plurality of button 3.Circuit board 32 is arranged on base plate 30, and each button 3 is arranged on base plate 30, and button 3 is available for users to press, and then carries out the function of user institute wish input.Keycap proposed by the invention design can be applicable at least on one of them of a plurality of buttons 3, its quantity number is looked closely the practical application of keyboard 2 and is determined, the button 3 that has this design for one of them is below described, the structural design that has the button 3 of same design as for other, it can be by that analogy.
Refer to Fig. 3, Fig. 3 is that button 3 in Fig. 2 is along the generalized section of X-X hatching.As shown in Figure 3, button 3 comprises base plate 30, circuit board 32, luminescence unit 34, keycap 36, liftable supporter 38 and elastic component 40.Circuit board 32 is arranged on base plate 30, and luminescence unit 34 is electrically connected at circuit board 32, and circuit board 32 is formed with assembling slotted eye 321 on the position of contiguous luminescence unit 34.Keycap 36 is arranged at the top of circuit board 32, and liftable supporter 38 is arranged between keycap 36 and base plate 30.In this embodiment, circuit board 32 can be film circuit board, and luminescence unit 34 can be light-emitting diode (Light Emitting Diode, LED).In addition, elastic component 40 is arranged between circuit board 32 and keycap 36, and elastic component 40 is used to provide elastic force so that the relative circuit board 32 of keycap 36 moves up and down.In addition, in this embodiment, elastic component 40 can be rubber washer (rubber dome), but not as limit.For instance, it also can be dome reed (metal dome), in other words, so long as the structural design of elastic force to keycap 36 can be provided, all belongs to the category that the present invention protects.
It is worth mentioning that on circuit board 32, to there are a plurality of switches 322, thin film switch (membrane switch) or other triggering property switch for example, a plurality of switches 322 are corresponding a plurality of buttons 3 respectively.When the keycap 36 of button 3 is pressed, the corresponding switch 322 that elastic component 40 gets final product on circuits for triggering plate 32, and then carry out the function that user institute wish is inputted.
Further, keycap 36 has the first chute 361 and the first draw-in groove 363, and base plate 30 has the second chute 303 and the second draw-in groove 305.Liftable supporter 38 further comprises the first strutting piece 381 and the second strutting piece 383, wherein the second strutting piece 383 and the first strutting piece 381 pivot joints.The first strutting piece 381 has the first sliding part 3810 and the first articulated section 3812.When assembling the first strutting piece 381, the first sliding part 3810 is mounted slidably in the first chute 361, and the first articulated section 3812 is articulated in the second draw-in groove 305 rotationally.The second strutting piece 383 has the second sliding part 3830 and the second articulated section 3832.When assembling the second strutting piece 383, the second sliding part 3830 is mounted slidably in the second chute 303, and the second articulated section 3832 is articulated in the first draw-in groove 363 rotationally.By this, when the keycap 36 of button 3 is pressed, keycap 36 can move up and down with respect to base plate 30 by liftable supporter 38.
As shown in Figure 3, button 3 also includes shading cover 42, on the position of the assembling slotted eye 321 of base plate 30 corresponding circuits plates 32, is formed with accommodation space 301, in this embodiment, accommodation space 301 can be through hole, but not limit by this, and it also can be the groove that does not run through base plate 30.The first side S1 of shading cover 42 has extended to form side arm 421 downwards, side arm 421 has extended to form the first shirt rim 422, side arm 421 is arranged in assembling slotted eye 321, the first shirt rim 422 is placed in accommodation space 301 and is attached on circuit board 32, by this, shading cover 42 can be fixed on circuit board 32 and cover in luminescence unit 34.In addition, shading cover 42 has light hole 423.By this, the light that luminescence unit 34 is launched can penetrate outside shading cover 42 via light hole 423.Further, keycap 36 has transmittance section 365 in the position of corresponding light hole 423.Thus, the light that luminescence unit 34 is launched can penetrate outside keycap 36 via the light hole 423 of shading cover 42 and the transmittance section of keycap 36 365, thereby reaches the effect that makes button 3 luminous.In addition, as shown in Figure 3, in this embodiment, extensible second shirt rim 424 that is formed with of the second side S2 of shading cover 42 can more firmly be fixed on circuit board 32 shading cover 42 to be attached on circuit board 32, to use.
See through above-mentioned configuration, the present invention can utilize the side arm 421 of shading cover 42 to be arranged in the assembling slotted eye 321 of circuit board 32 and the first shirt rim 422 of shading cover 42 is placed in the design in the accommodation space 301 of base plate 30, to replace prior art, directly shading cover is attached to the design on circuit board, thereby produce the whole height of reduction shading cover 42 to reduce the effect in the required key inside space taking of shading cover 42, use the restriction of pressing stroke that effectively reduces by 42 pairs of keycaps 36 of shading cover, be beneficial to the slimming design of button 3, and the problem that also can avoid further keycap 36 to interfere with shading cover 42 in the process of pressing and cause assembly to damage.In addition, see through the contraposition assembling design of the assembling slotted eye 321 on shading cover 42 and circuit board 32, operating personnel can be assembled to shading cover 42 on the position that corresponds to luminescence unit 34 exactly, use light can accurately be sent from light hole 423 forwards, thus the illumination effect of lifting button 3.
It is worth mentioning that, the first shirt rim 422 of above-mentioned shading cover 42 and the accommodation space 301 of the second shirt rim 424 and base plate 30 are omissible configuration, use the object that reaches the structural design of simplifying button 3, that is to say, in another embodiment of configuration that omits the first shirt rim 422 of shading cover 42 and the accommodation space 301 of the second shirt rim 424 and base plate 30, button 3 can only utilize the side arm 421 of shading cover 42 to be fixed on the design in the assembling slotted eye 321 of circuit board 32, reach the object that shading cover 42 is fixed on circuit board 32 and covers in luminescence unit 34, the side arm 421 of shading cover 42 can adopt common fixed form carry out and the assembling slotted eye 321 of circuit board 32 between fixing, for instance, side arm 421 can the friction tight mode of structure be inserted in assembling slotted eye 321, or utilize viscose juncture cemented in assembling slotted eye 32, its associated description is common in prior art, therefore repeat no more in this.
Certainly; the present invention also can have other various embodiments; in the situation that not deviating from spirit of the present invention and essence thereof; those of ordinary skill in the art can make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
