Embodiment
See also Fig. 1, Fig. 1 is the schematic diagram of the keyboard 10 of the embodiment of the invention.Keyboard 10 includes base plate 12 and a plurality of button 14.Base plate 12 can be monolithic metal, and 14 of a plurality of buttons are separately positioned on the base plate 12.
See also Fig. 2, Fig. 2 is the element exploded perspective view of the button 14 of the embodiment of the invention.Take a button 14 as example, button 14 includes keycap 16, lifting supporting mechanism 18, the first locating part 20, elastomer 22 and film circuit board 24.Lifting supporting mechanism 18 and elastomer 22 are arranged at respectively between keycap 16 and the base plate 12, in the parallel process of keycap 16 relative base plates 12 in order to support keycap 16.Film circuit board 24 is arranged between elastomer 22 and the base plate 12, when keycap 16 is pressed and so that elastomer 22 when strain occurs, but elastomer 22 striking film circuit boards 24 and produce a signal of telecommunication.In the present embodiment, elastomer 22 is a rubber elastomer, but not as limit, the user can select elastomeric material according to actual needs voluntarily.The first locating part 20 can adopt with keycap 16 integrated modes and form, and also can adopt the mode that is fixedly connected with to be connected with keycap 16, not as limit.
In order to control the actuating travel of button 14, the present invention is connected in keycap 16 with the first locating part 20.The first locating part 20 has the first guide groove 32, and can relatively movable mode being arranged on the first guide block 26 of lifting supporting mechanism 18.The length H of the first guide groove 32 is for being set as the ultimate range of keycap 16 relative base plate 12 motions, therefore when keycap 16 is pressed by external force, the first guide block 26 just can slide in the first guide groove 32, until the first guide block 26 only is butted on an end of the first guide groove 32, make to stop keycap 16 moving relative to base plate 12.In other words, the first guide groove 32 in fact vertically extends, so that the coasting distance of the first guide block 26 in the first guide groove 32 can be equal to the shift motion that keycap 16 moves up and down in fact.
In addition, the second lifters 30 of the present invention also can comprise the second guide block 34, be arranged on the position of relative the first guide block 26 on the second main body 301, and lifting supporting mechanism 18 also can comprise the second locating part 36, be connected in another side of relative the first locating part 20 on the keycap 16.The first locating part 20 and the second locating part 36 utilize respectively the first guide groove 32 and the second guide groove 38 with chimeric corresponding the first guide block 26 and the second guide block 34 of being socketed on, therefore, button 14 is in operating process, and its keycap 16 just can balancedly utilize the first locating part 20 and the second locating part 36 to reach the purpose of Stroke Control.
See also Fig. 3 and Fig. 4, Fig. 3 is the schematic diagram of the keycap of the button of the embodiment of the invention when being positioned at the peak of its shift motion, and Fig. 4 is the schematic diagram of the keycap of the button of the embodiment of the invention when being positioned at the minimum point of its shift motion.As shown in Figure 3, keycap 16 is positioned at the peak of its shift motion, and this moment, the first guide block 26 was connected to the lower end of the first guide groove 32.Then, as shown in Figure 4, when the user presses keycap 16, along with keycap 16 moves closer to base plate 12, the first guide block 26 also can slide along the first guide groove 32, until the first guide block 26 backstops just stop the shift motion of keycap 16 relative base plates 12 in the upper end of the first guide groove 32.In other words, button 14 of the present invention utilizes the combination of the first guide block 26 and the first locating part 20 to limit the shift motion of keycap 16.Therefore the shift motion of keycap 16 can limit keycap 16 movings range accurately corresponding to the length H of the first guide groove 32 of the first locating part 20, promotes the operating handle of button 14.
Comprehensive, the edge in keycap in button of the present invention and the keyboard arranges locating part, sees through the combination that guide groove is embedded in guide block, so that locating part is set on the lifting supporting mechanism in mobilizable mode.Locating part of the present invention is except limiting the shift motion of the relative base plate of keycap by its guide groove length, also can assist and improve the structural stability that keycap is incorporated into the lifting supporting mechanism, therefore keycap is difficult for rocking when mobile, therefore that button of the present invention and keyboard thereof have is simple in structure, processing ease, cheap, the high structural rigidity of cost of manufacture, and be easy to the advantage of the shift motion of precisely control product.
Certainly; the present invention also can have other various embodiments; in the situation that do not deviate 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.
