Accompanying drawing explanation
Fig. 1 is the three-dimensional exploded view of the press-key structure of a kind of keyboard of the utility model;
Fig. 2 is the stereogram of keycap in Fig. 1.
In figure: 1, base; 11, positioning supports boss; 12, concane gap; 13, clinching 13; 14, printing opacity through hole 14; 3, film circuit board; 31, hole is dodged; 5, elastic component; 51, printing opacity through hole; 7, linear fixture is justified; 71, power point; 72, balance pivot; 73, resistance point; 74, the linear fixture of cylinder; 9, keycap; 91, buckle; 92, sliding tray; 93, guide angle is assembled.
Embodiment
As shown in Figure 1-2, the press-key structure of a kind of keyboard of the utility model embodiment, comprises base 1, by lower film circuit board 3, elastic component 5, the linear fixture 7 of circle and keycap 9 from being above successively set on base 1.
Base 1 is provided with at least two positioning supports boss 11, multiple clinching 13 and multiple printing opacity through hole 14, and positioning supports boss 11 is provided with concane gap 12; Film circuit board 3 is provided with corresponding with positioning supports boss 11 and clinching 13 dodges hole 31; Elastic component 5 is provided with at least one printing opacity through hole 51; The linear fixture 7 of circle is provided with the leverage of balance pivot 72, resistance point 73 and power point 71 composition; Keycap 9 is provided with at least two buckles 91, and buckle 91 is provided with the sliding tray 92 that coordinates with circle linear fixture 7 and assembles guide angle 93.
Wherein, justifying linear fixture 7 is the linear fixture 74 of cylinder.The linear of the linear fixture of cylinder 74 comprises linear, many fold-line-shapeds and shaped form.
By the positioning supports boss 11 on base 1 and clinching 13, assembling location and fixation are played to the linear fixture 7 of circle; When printing opacity through hole 14 on base 1 is directed to and does backlight keycap, play and increase glazed area effect; The effect of dodging is played to this press-key structure in hole 31 of dodging on film circuit board 3, and plays positioning action to the assembling of film circuit board 3; Printing opacity through hole 51 on elastic component 5, for when doing backlight keycap, plays and increases glazed area effect; The linear fixture 7 of circle adopts the linear fixture 74 of cylinder, plays an important role, provide good guide effect to the assembling of keycap 9 to reduction keyboard thickness; Leverage on the linear fixture 7 of circle, plays reduction key press, improves key stroke and feel effect; Fixed structure on the linear fixture 7 of circle and the combination of lever, play and simplify press-key structure, reduction button thickness and reduce costs effect; Sliding tray on keycap 9 92 pairs of keycaps 9 play the spacing and guide effect that moves up and down; Guide effect is played in the assembling of the assembling guide angle 93 pairs of keycaps 9 on keycap 9.
During concrete assembling: when film circuit board 3 is arranged on base 1, the positioning supports boss 11 on base 1, clinching 13 coordinate position film circuit board 3 with the holes 31 of dodging on film circuit board 3.Elastic component 5 is arranged on film circuit board 3.When the linear fixture 7 of circle is arranged on base 1, the positioning supports boss 11 on base 1 carries out plane positioning to the linear fixture 7 of circle, and the clinching 13 on base 1 is fixed the linear fixture 7 of circle.When keycap 9 is arranged on the linear fixture 7 of circle, because linear fixture 7 cross section of circle is circular, have assembling guide effect to the buckle 91 on keycap 9, add on buckle 91 and have guide angle 93 also to play guide effect to assembling, convenient keycap 9 loads on the linear fixture 7 of circle.
During concrete use: when keycap 9 is not subject to the power of pressing downwards in nature, base 1 supports film circuit board 3, film circuit board 3 supports elastic component 5, and elastic component 5 supports the resistance point 73 on the linear fixture 7 of circle, and the power point 71 on the linear fixture 7 of circle supports keycap 9.Clinching 13 on base 1 is fixed motionless to the linear fixture 7 of circle.When buckle 91 on keycap 9 is assembled on the linear fixture 7 of circle, secure the plan position approach of keycap 9, the sliding tray 92 of keycap 9 with justify linear fixture 7 and have and corresponding slide up and down space.
When keycap 9 is subject to the power of pressing downwards, the relative sliding space that sliding tray 92 has with the linear fixture 7 of circle, makes keycap 9 move downward.When keycap 9 moves downward, the power point 71 on the linear fixture 7 of circle moves downward simultaneously.Due to the leverage effect on the linear fixture 7 of circle, resistance point 73 also does and moves downward accordingly.Resistance point 73 is pressed in downwards on elastic component 5, makes elastic component 5 deformation.Elastic component 5 deformation is pressed into the switch of film circuit board 3, thus realizes the function of input through keyboard.
When the power that keycap 9 is subject to pressing is downwards cancelled, because elastic component 5 deformation resets, resistance point 73 is stressed simultaneously moves upward, due to the leverage effect on the linear fixture 7 of circle, power point 71 on the linear fixture 7 of circle upwards does corresponding motion simultaneously, and power point 71 moves upward thus keycap 9 is also moved upward simultaneously.Due to the sliding tray 92 on keycap 9 and the relative spacing relation of slip of the linear fixture 7 of circle, keycap 9 is moved upward stopping, and keycap 9 resets.
The utility model press-key structure, is guaranteeing that button has scissors corner structure more conventional than keyboard of notebook computer in the market on good use feel basis also thin.Notebook computer, flat computer keyboard, cell phone keyboard etc. can be helped to a certain extent to reduce certain thickness, and the life for people brings more portable service.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
