Embodiment
See also Fig. 1 and Fig. 2, Fig. 1 is the explosive view according to the button 1 of one of the utility model preferred embodiment, and Fig. 2 is the sketch map after button 1 assembling.Button 1 comprises base plate 12, loam cake 14, interval box 16, film circuit board 18, elasticity dome 20, press-key structure 22 and connected structure 24.Base plate 12 is connected via connected structure 24 (as shown in Figure 5) with loam cake 14; 16 of film circuit board 18 and interval box are arranged between base plate 12 and the loam cake 14 in regular turn; Press-key structure 22 is arranged on the base plate 12, and elasticity dome 20 corresponding press-key structures 22 are arranged on the film circuit board 18 and are formed at corresponding switch contact on the film circuit board 18 being depressed with triggering by press-key structure 22.
Further, connected structure 24 comprises first interface components 242 and second interface components 244.First interface components 242 is arranged on the base plate 12 and comprises second stop section 2426 that two first stop sections 2422, correspondences being connected to base plate 12 are formed at two passages 2424 on 2422 sides, first stop section and are connected to base plate 12.Second interface components, 244 corresponding first interface components 242 are arranged on the loam cake 14 and comprise two connecting portions 2442 connecting with loam cake 14, reach the abutting part 2446 that is connected with loam cake 14 with connecting portion 2442 corresponding two kinks that are connected 2444.Kink 2444 corresponding first stop sections 2422 are provided with, and abutting part 2446 corresponding second stop sections 2426 are provided with.In present embodiment, first stop section 2422 and passage 2424 are symmetrical set with respect to second stop section 2426, and kink 2444 is symmetrical set with respect to abutting part 2446 accordingly, and this helps Stability Analysis of Structures, but the utility model is not as limit.Kink 2444 passes corresponding passage 2424 and is corresponding first stop section, 2422 blocks, and abutting part 2446 is tight against second stop section 2426 with respect to kink 2444.
What remark additionally is; In present embodiment; First stop section, 2422 block kinks 2444 can prevent that base plate 12 and loam cake 14 break away from, and abutting part 2446 is tight against second stop section 2426 and can makes 14 stable spacings that form of base plate 12 and loam cake, and then formation start space; For other member start, for example press-key structure 22 and elasticity dome 20 pushes, triggers start.Aforementioned intervals also keep to such an extent that only realize by interval box 16.In present embodiment; First interface components 242 is integrally formed with base plate 12; All towards loam cake 14 outstanding formation, second interface components 244 is integrally formed with loam cake 14 for first stop section 2422 and second stop section 2426, and for example base plate 12 and loam cake 14 are all directly with the metallic plate drawing; But this simplified structure also be convenient to make, but the utility model is not as limit.In addition, in present embodiment, first interface components 242 is arranged on the base plate 12, and second interface components 244 is arranged on the loam cake 14 accordingly, but the utility model is not as limit; For example first interface components 242 is arranged on the loam cake 14, and second interface components 244 is arranged on the base plate 12 accordingly, also can realize the utility model.
Supplementary notes is that though button 1 shown in Figure 2 only uses single connected structure 24 in single side, the utility model is not as limit again.In addition, in present embodiment, film circuit board 18 is arranged on the base plate 12, so film circuit board 18 has opening 182 and passes for first interface components 242; But the utility model is not as limit, and for example if film circuit board 18 is arranged under the base plate 12, then base plate 12 needs elasticity dome 20 places formation opening in the corresponding diagram 1 so that the make and break contact that is formed on the film circuit board 18 can be triggered by press-key structure 22.
Press-key structure 22 comprises cantilever member 222 and the keycap 224 on the cantilever member 222 is set; The stiff end 2222 of cantilever member 222 is fixedly connected on loam cake 14, and keycap 224 is exposed to loam cake 14 and can be pressed down the make and break contact that is formed at film circuit board 18 with extruding elasticity dome 20 with triggering.In present embodiment, cantilever member 222 roughly is the ㄇ font, is fixedly connected on loam cake 14 across second interface components 244.Because contiguous second interface components 244 of cantilever member 222 (or being called whole press-key structure 22) (or meaning connected structure 24) is so press-key structure 22 can be obtained firm support structure.In present embodiment, though press-key structure 22 realizes that with cantilever design the utility model is not as limit, for example the shear-type key structure of convention also has being suitable for of the utility model.
In first interface components 242 and process that second interface components 244 is connected, after the kink 2444 of second interface components 244 was waited to pass passage 2424 in practical application, again by bending, its wrap direction was as shown in Figure 3.In present embodiment, first stop section 2422 has surface 2428 (seeing also Fig. 1), is the bottom surface of first stop section 2422 among Fig. 1, and it goes up one 2448 of definition kink 2444, is approximately perpendicular to surperficial 2428.Before passing passage 2424, kink 2444 is not bending (shown in solid line among Fig. 3) as yet; After passing passage 2424, kink 2444 can see through tool and bend (shown in dotted line among Fig. 3) to be tight against surface 2428 along axle 2448.In another embodiment, the overbending direction of kink 2444 is different from the former, and is as shown in Figure 4.In this embodiment, kink 2,444 one 2450 of definition on it is roughly parallel to surface 2428.After passing passage 2424, kink 2444 can see through tool and bend (shown in dotted line among Fig. 3) to be tight against surface 2428 along axle 2450.So in practical application, the mode that the utility model kink 2444 is tight against first stop section 2422 is not exceeded with previous embodiment.
See also Fig. 5, it is the sketch map according to the keyboard 3 of one of the utility model preferred embodiment.With regard to structure; Keyboard 3 comprises a plurality of buttons 1; But base plate 12, loam cake 14, interval box 16, film circuit board 18 can be shared; During used on the historical facts or anecdotes border, keyboard 3 comprised base plate 32, loam cake 34, interval box 36, film circuit board 38, a plurality of press-key structure 22, a plurality of connected structure 24 and a plurality of elasticity dome 20.Each press-key structure 22 a corresponding connected structure 24 and elasticity dome 20.It changes the related description that aforementioned keys 1 can be directly consulted in explanation keyboard 3 each assembly, does not give unnecessary details in addition.
What remark additionally is; In present embodiment, keyboard 3 also also is provided with connected structure 24a, 24b in the both sides of total except that corresponding each press-key structure 22 is provided with the connected structure 24; Can make total more firm, but the utility model is not as limit.In addition, in present embodiment, only in corresponding press-key structure 22 place's hollow outs, still can there be supporting construction at all the other positions to interval box 36, and are as shown in Figure 6, and this also helps total more firm, but the utility model is not also as limit.
As previously mentioned; Compare the button and the keyboard of prior art, button of the utility model and keyboard adopt new assembly to be connected framework, simplify the product overall structure; Still can take into account the overall structure stability, it is huge and be difficult to lightening problem to solve convention button and keyboard structure.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
