Embodiment
The direction term mentioned in following examples such as: upper and lower, left and right, front or rear etc., is only the direction with reference to annexed drawings.Therefore, the direction term of use is used to illustrate and is not used for limiting the present invention.Refer to Fig. 1, Fig. 1 is the schematic diagram of first embodiment of the invention keyboard 1.As shown in Figure 1, keyboard 1 comprises base plate 30 and a plurality of button 2, and button 2 is arranged on base plate 30, for user pressing, and then perform user institute for input function, such as input characters, symbol or numeral etc.
Refer to Fig. 2 to Fig. 4, Fig. 2 is the schematic appearance of first embodiment of the invention button 2, and Fig. 3 is the exploded perspective view of first embodiment of the invention button 2, and Fig. 4 is the generalized section of first embodiment of the invention button 2.As shown in Figures 2 to 4, button 2 includes keycap 32 and lifting supporting mechanism 34, and keycap 32 is arranged at above base plate 30, and lifting supporting mechanism 34 is connected between base plate 30 and keycap 32.When the keycap 32 of user's pressing keys 2, the pressing force of user can be averagely allocated to keycap 32 by lifting supporting mechanism 34, can move downward by opposed bottom 30 reposefully to make keycap 32.In other words, be elevated supporting mechanism 34 and when keycap 32 is pressed, pressing force can be averagely allocated to keycap 32, to drive keycap 32 along the descent direction X1 shown in Fig. 4 reposefully near base plate 30.
In this embodiment; lifting supporting mechanism 34 can include two balance bars (linkbar); and lifting supporting mechanism 34 of the present invention comprise balance bar quantity can be not limited to that this embodiment is graphic to be illustrated; such as be elevated supporting mechanism 34 and also only can include a balance bar; as long as that is lifting supporting mechanism 34 includes the structural design of at least one balance bar, all in the category that the present invention protects.In addition, the structural design of lifting supporting mechanism 34 of the present invention can be not limited to that this embodiment is graphic to be illustrated, such as, be elevated supporting mechanism 34 and also can be scissor (plunger) mechanism.As for the above-mentioned whichever design of employing, determined by actual demand.
As shown in Figures 2 to 4, button 2 separately includes connecting elements 36, elastic component 38, sliding groove structure 40 and pin-jointed structure 42, and connecting elements 36 has sliding part 361 and articulated section 363, and elastic component 38 has first end 381 and the second end 383.Sliding groove structure 40 is arranged at base plate 30 and it moves towards substantially parallel to the reset direction Y1 shown in Fig. 4, the sliding part 361 of connecting elements 36 is slidably disposed in sliding groove structure 40, the sliding part 361 of connecting elements 36 just can slidably be arranged on base plate 30 by this, and because the trend of sliding groove structure 40 is substantially parallel to reset direction Y1, therefore the sliding part 361 that sliding groove structure 40 can limit connecting elements 36 slides along reset direction Y1 or along the deformation direction Y2 in contrast to reset direction Y1.
In this embodiment, connecting elements 36 made by metal material, but can not limit by this, and such as connecting elements 36 also can made by plastic cement material.As for the above-mentioned whichever design of employing, determined by actual demand.In addition, pin-jointed structure 42 is arranged at keycap 32, and pin-jointed structure 42 can be used to the articulated section 363 of pivot joint connecting elements 36, and the articulated section 363 of connecting elements 36 just can pivotally be arranged on keycap 32 by this.In this embodiment, elastic component 38 is arranged in sliding groove structure 40, and the first end 381 of elastic component 38 is connected to the sliding part 361 of connecting elements 36, and the second end 383 of elastic component 38 is connected to the inwall 401 of sliding groove structure 40.In this embodiment, elastic component 38 can be spring, but the structural design of elastic component of the present invention 38 can be not limited to that this embodiment is graphic to be illustrated, and such as elastic component 38 also can be elastic piece structure or rubber mount etc.As for the above-mentioned whichever design of employing, determined by actual demand.
Refer to Fig. 4 and Fig. 5, Fig. 5 is the generalized section that first embodiment of the invention button 2 is in pressed state.As shown in FIG. 4 and 5, when the keycap 32 of user's pressing keys 2, lifting supporting mechanism 34 drives keycap 32 along the descent direction X1 shown in Fig. 4 near base plate 30, the now articulated section 363 of connecting elements 36 pin-jointed structure 42 pivotable relatively, and the sliding part 361 that sliding groove structure 40 limits connecting elements 36 slides along deformation direction Y2.Thus, keycap 32 just can be moved to pressing position as shown in Figure 5 by reset position as shown in Figure 4, to trigger the circuit board (not being illustrated in figure) be arranged on base plate 30, and then perform user institute for input function.It is worth mentioning that, in the process that keycap 32 is pressed, the sliding part 361 of connecting elements 36, along deformation direction Y2 compression elastic piece 38, stores elasticity potential energy to make elastic component 38.
Further, when user complete for input function time, the keycap 32 of user's no longer pressing keys 2, now elastic component 38 just can discharge this elasticity potential energy to produce elastic-restoring force along reset direction Y1, use and drive the sliding part 361 of connecting elements 36 to slide along reset direction Y1 in sliding groove structure 40, and make connecting elements 36 articulated section 363 pivotable relatively.Thus, connecting elements 36 just can drive keycap 32 along the ascent direction X2 in contrast to descent direction X1 away from base plate 30, and moves to this reset position as shown in Figure 4 by this pressing position as shown in Figure 5.
It is worth mentioning that, the trend (i.e. reset direction Y1 or deformation direction Y2) of sliding groove structure 40 is substantially perpendicular to descent direction X1 or ascent direction X2, therefore sliding groove structure 40 can save button 2 in descent direction X1 or ascent direction X2(and button 2 short transverse) volume, button 2 of the present invention just can reduce the whole height of button by this, thus is conducive to the development trend of the slimming of keyboard 1.Moreover as shown in Figure 4, have an angle θ between connecting elements 36 of the present invention and base plate 30, known via experiment, the time that the FORCE FEEDBACK peak value (peakforce) that the size of angle θ and button 2 produce in the process pressed occurs is proportionate.That is, when angle θ is larger, button 2 FORCE FEEDBACK peak value in the process of pressing more early occurs; Otherwise, when angle θ more hour, button 2 more late generation of FORCE FEEDBACK peak value in the process of pressing.It is worth mentioning that, angle θ can not equal 90 degree, that is be not orthogonal to base plate 30 and keycap 32 in the upper connecting elements 36 of design, cannot pivotable and sliding part 361 cannot to slide the situation that caused button 2 blocks to avoid the articulated section 363 of connecting elements 36 when button 2 is pressed.
