Description
Technical field
The present invention relates to a kind of keyboard equipment, more particularly to a kind of mechanical thin-film keyboard.
Background technology
With reference to Fig. 1, conventional membrane keyboard mainly includes keycap 11, is arranged on scissor (the X-type support of the lower section of keycap 11
12) and silica gel push-button 13, X-type support 12 is used for fixing and stable keycap 11, then bottom setting of arranging in pairs or groups thin film electricity
Road floor 14；Wherein, silica gel push-button 13 is bowl-shape in back-off, and its rim of a bowl portion is arranged in membrane circuit layer 14, and its bowl of bottom projection is used for
Keycap 11 is contacted, its internal shaft core with connection bump.When pressing keycap 11, silica gel push-button 13 is then driven simultaneously by keycap 11
Down trigger, make axle stamen inside silica gel push-button 13 drive the realization that contacts with each other of the electrode contact point 15 in membrane circuit layer 14 to lead
It is logical, and reset keycap 11 by the elastic force of silica gel push-button 13.Coordinate silica gel push-button 13 because membrane keyboard employs scissor
Structure, and coordinate frivolous membrane circuit layer 14, thus have the advantages that frivolous, cost is low.With reference to Fig. 2, because it is used
Silica gel push-button 13 is as trigger element, and it is turned on, and stroke S1 (mm) is shorter and corresponding conducting power F1 (g) is smaller, can be easily
Realize triggering and conducting, but the feel of operator can be poor during its actual mechanical process, be frequently present of no pressing touch and
Cause the defect pressed repeatedly, and the relative mechanical component life of silica gel push-button 13 is shorter.
With reference to Fig. 3, conventional mechanical keyboard mainly includes keycap, the key axle 21 being connected with keycap, the line of connecting key axle 21
Property spring 22, the electroconductive elastic sheet 23 of corresponding keys axle 21 and the flexible PCB wiring board 24 for installing Hookean spring 22.Work as pressing
During keycap, Hookean spring 22 is compressed by key axle 21, so that trigger electroconductive elastic sheet 23 and turn on conducting wire 25, and by linear
Spring 22, which is realized, to be resetted.With reference to Fig. 4, due to which employs the mechanical structure of key axle 21 and Hookean spring 22 as trigger element,
It turns on that stroke S2 (mm) is longer and corresponding conducting power F2 (g) is larger, thus during pressing sense of touch preferably, so as to have sensitivity
The advantage of high, good hand touch and long lifespan, has very big influence power, its reaction speed and feel are all in game player group
There is the advantage that membrane keyboard is incomparable.But this kind of mechanical keyboard coordinates Hookean spring 22 due to needing by key axle 21,
Each button is required for an independent switch (electroconductive elastic sheet 23) and can only use the PCB circuits with certain mechanical strength
Plate 24 could realize the installation connection of said structure, thus have the shortcomings that overall volume is thick and heavy and cost is high.
Thus, it is an object of the invention to develop, one kind can with combination film keyboard, frivolous, cost be low and mechanical keyboard is clever
The mechanical thin-film keyboard of both sensitivity height, good hand touch and long lifespan advantages, to meet need of the society to high quality keyboards now
Ask.
