[embodiment]
See also Fig. 1 and Fig. 2, Fig. 1 is the sketch map according to the keyboard 10 of the utility model one embodiment, and Fig. 2 is the part explosive view of keyboard 10 shown in Figure 1.Like Fig. 1 and shown in Figure 2, keyboard 10 comprises base plate 12, framework 14 and a plurality of button 30.Framework 14 all is arranged on the base plate 12 with button 30, and framework 14 has a plurality of containing holes 140.A plurality of buttons 30 are corresponding a plurality of containing holes 140 respectively, and after framework 14 and button 30 all were arranged on the base plate 12, the top of button 30 protruded on the framework 14.Thus, button 30 can supply the user to push, and then carries out the function of user institute desire input.
See also Fig. 3, it is button 30 a shown in Figure 1 profile along the X-X line.As shown in Figure 3, button 30 includes keycap 32, circuit board 34, film 36, liftable supporter 38, an elastic component 40 and a buffer structure 42.Circuit board 34 is arranged on the base plate 12, and film 36 is arranged on the circuit board 34, and film 36 is used for protective circuit plate 34, causes circuit board 34 short circuits to prevent foreign matters such as dust.In this embodiment, film 36 can be by forming like materials such as rubber.Liftable supporter 38 is arranged between base plate 12 and the keycap 32.Further, keycap 32 has first chute 320 and first draw-in groove 322, and base plate 12 has second chute 120 and second draw-in groove 122.Liftable supporter 38 comprises first strutting piece 380 and second strutting piece 382, and wherein second strutting piece 382 and first strutting piece 380 articulate.First strutting piece 380 has first sliding part 3800 and first articulated section 3802.When assembling first strutting piece 380, first sliding part 3800 is mounted slidably in first chute 320, and first articulated section 3802 is articulated in second draw-in groove 122 rotationally.Second strutting piece 382 has second sliding part 3820 and second articulated section 3822.When assembling second strutting piece 382, second sliding part 3820 is mounted slidably in second chute 120, and second articulated section 3822 is articulated in first draw-in groove 322 rotationally.Thus, connect design through above-mentioned structure, keycap 32 can move up and down with respect to base plate 12 by liftable supporter 38.
In addition, elastic component 40 also is arranged between keycap 32 and the base plate 12, required elastic force source when moving up and down as keycap 32 relative base plates 12.In practical application, elastic component 40 can be rubber washer (rubber dome).In addition, have on the circuit board 34 and button 30 corresponding switch (not shown)s, for example thin film switch (membrane switch) or other triggering property switch.When button 30 is pressed, the switch on the elastic component 40 meeting circuits for triggering plates 34, and then carry out the function that user institute desire is imported.
Please consult Fig. 3 again; Keycap 32 includes body 324 and abutting part 326; Body 324 is arranged in the corresponding containing hole 140 movably; And abutting part 326 stretches out from the edge of body 324, and is formed with stopper section 142 respectively on the position on every side of framework 14 corresponding each containing hole 140.In this embodiment, buffer structure 42 is arranged on the abutting part 326 of keycap 32 and can be made up of the rubber material, and buffer structure 42 is used in the process that body 324 moves upward, the stopper section 142 that stops abutting part 326 contact frame 14 of keycap 32.In other words; When the body 324 of keycap 32 moves upward with respect to base plate 12 by liftable supporter 38; Buffer structure 42 on the abutting part 326 of keycap 32 can be connected to the stopper section 142 of framework 14, but not directly is connected to the stopper section 142 of framework 14 by the abutting part 326 of keycap 32.Thus, button 30 is the damping characteristics of buffer structure 42 capable of using, with the bump power between buffering absorption abutting part 236 and stopper section 142.By this; Buffer structure 42 can reduce the noise that keyboard 10 is produced when using; To improve the noise jamming that the user collides and brought because of keycap and framework when using keyboard; More can help simultaneously the use of keyboard under quiet environment (for example office, library etc.), thereby promote the application of elastic of keyboard on all kinds of environment.
In practical application; Keycap 32 is made up of plastic cement material, rubber material, metal material or its combination in any material; And buffer structure 42 is preferably integrally formed with the mode of extra quality ejaculation with keycap 32, but not as limit, it also can utilize other common Fixed Design.For instance, buffer structure 42 also can be the independent component that is formed separately with keycap 32, the mode of buffer structure 42 with gummed is adhered on the abutting part 326 of keycap 32 again.What deserves to be mentioned is that buffer structure 42 can be half a cylindrical projections structure or a hemispherical projections structure, thus; Line contacts or the design of some contact through being essentially between buffer structure 42 and the stopper section 142; The utility model can reduce the noise that keyboard 10 is produced further when using, but not limit by this, and buffer structure 42 also can be other raised structures with identical buffering effect; Like flat column raised structures etc.; In other words, so long as utilize buffer structure to be formed at the design between the stopper section of abutting part and framework of keycap, all belong to the protection range of the utility model; Adopt which kind of structural design as for buffer structure, it is looked closely the practical application of keyboard 10 and decides.
In addition, the set-up mode of buffer structure 42 can be not limited to the mentioned mode of the foregoing description.See also Fig. 4, its be according to another embodiment of the utility model button 30 ' profile.Like Fig. 4 and shown in Figure 3, button 30 ' be that with the main difference part of above-mentioned button 30 buffer structure 42 is arranged on the stopper section 142 of framework 14.As for button 30 ' the action principle of buffer structure 42, it is similar in appearance to the action principle of the buffer structure 42 of button 30, for the sake of clarity, so repeat no more in this.
See also Fig. 5, it is the button 30 according to another embodiment of the utility model " profile.Like Fig. 5 and shown in Figure 3, button 30 " is that with the main difference part of above-mentioned button 30 buffer structure 42 is arranged on the stopper section 142 of abutting part 326 and framework 14 of keycap 32 simultaneously, and is against each other between buffer structure 42 and the buffer structure 42.When the body 324 of keycap 32 moved upward with respect to base plate 12 by liftable supporter 38, the buffer structure 42 on the abutting part 326 of keycap 32 can be connected to the buffer structure 42 on the stopper section 142 of framework 14.Thus, so the vibrations that produced in the time of can absorbing butt because of buffer structure 42 are the bump power between available buffer abutting part 236 and the stopper section 142.By this, buffer structure 42 can reduce the noise that keyboard 10 is produced when using.
Compared to prior art; The utility model utilization optionally is arranged at the buffer structure on the abutting part of stopper section and/or keycap of framework; In the process that moves upward with body at keycap; Stop abutting part contactor banking stop portion, and utilize the damping characteristics of buffer structure, absorb the bump power between abutting part and the stopper section with buffering.Thus; The buffer structure of the utility model can reduce the noise that keyboard is produced when using; To improve the noise jamming that the user collides and brought because of keycap and framework when using keyboard; More can help simultaneously the use of keyboard under quiet environment, thereby promote the application of elastic of keyboard under all kinds of environment.
The above is merely the embodiment of the utility model, and the utility model protection range is as the criterion with claim.
