Embodiment

As shown in Figures 1 to 4, the utility model is a kind of slim condenser type keyboard：It includes：One keycap 10, one is built bridge Mechanism 20, an elastomer 30, a cone shaped elastic part 40, a button deckle board 50, a stator 60 and a sensor circuit plate 70.

On the keycap 10, its press component being generally square；Disymmetrical lead is formed on the basal surface of the keycap 10 The pivot connected slot 12 of chute 11 and two.

The bridge formation mechanism 20 (is commonly called as by 22 integral rotating mechanisms of intersecting axle pivot of one first framework 21 and one second framework For scissor type structure), and the apical margin of the bridge formation mechanism 20 and root edge are pivotally connected are linked to the keycap 10 and the button deckle board 50 respectively Between, form a bridge type press-key structure.

From the figure 3, it may be seen that the two corresponding slide-bars 211 that the epitaxial lateral overgrowth of 21 apical margin of the first framework two is stretched are articulated in the bottom of keycap 10 In the corresponding guide runner 11 of the two of face, the corresponding pivot 221 of the another apical margin of second framework 22 is in then rotationally to be articulated in the keycap In the corresponding pivot connected slot 12 of the two of 10 bottom surfaces；Then, the two corresponding slide-bars 222 that the epitaxial lateral overgrowth of 22 root edge of the second framework two is stretched slide Ground is located in the two corresponding guide runners 53 that the button deckle board 50 is folded upward at, and two epitaxial lateral overgrowths of the root edge of the first framework 21 are stretched Two corresponding pivots 212 be articulated in two corresponding pivot connected slots 52 of the button deckle board 50.

The middle position of first framework 21 is equipped with a pair of axis holes 213, and the middle position of second framework 22 stretches out There is a pair of pivot 223, enable two on first framework 21 corresponding axis holes 213 and two pivots 223 on second framework 22 Pivot joint links integral, and then is center of rotation by two pivot 223, and makes the first framework 21 and the second framework 22 formed Bridge type press-key structure has the effect of relative revolution.

On the elastomer 30, it is fixedly arranged on a pad 31, and is pushed up and pulled in the bottom surface of the keycap 10；Also, the pad 31 is set In on the button deckle board 50 and having multiple elongated holes 32, the bridge formation mechanism 20 passes the elongated hole 32 of the pad 31 and is pivotally connected chain It is connected to the button deckle board 50.

The button deckle board 50 has a perforation 51；The stator 60 has a fixing hole 61, and the sensor circuit plate 70 has There is a capacitive sensing area 71；Also, perforation 51 and the capacitive sensing area 71 of the fixing hole about 61 corresponding to the button deckle board 50.

Also, the cone shaped elastic part 40 top is pulled in the accommodation space of the internal layer of the elastomer 30, and the bottom of cone shaped elastic part 40 The perforation 51 of the button deckle board 50 is passed, and position is set in the fixing hole 61 for being fixed on the stator 60, and the cone shaped elastic part 40 It is metal material with the capacitive sensing area 71 corresponding to the sensor circuit plate 70.Wherein size of fixing hole 61 of the stator 60 etc. In or slightly larger than the bottom of cone shaped elastic part 40, the cone shaped elastic part 40 is set to be limited in the fixing hole 61, and then keep the cone The relative induction position of the bottom of shape elastic component 40 and the capacitive sensing area 71；Also, the cone shaped elastic part 40 is a metal conic bullet Spring, and base diameter is more than top diameter person.

Thus, when the keycap 10 is depressed, it presses downwards the top surface of elastomer 30 and makes the elastomer 30 downward Deformation, and then the cone shaped elastic part 40 is pressed towards the capacitive sensing area 71 of the sensor circuit plate 70 to compress its relative spacing, enter And its inductance capacitance variable quantity shows that it presses power with corresponding, output one is set to correspond to the keyboard pressing letter of the pressing force intensity Number.

As shown in Figure 4 A, when the keycap 10 is not pressed, the elastic force meeting ejection of the elastomer 30 keycap 10 is located at one First position P1, and the not yet depressed power of the cone shaped elastic part 40 also non-compressive deformation, now, the electricity of the sensor circuit plate 70 Hold induction zone 71 and also do not produce capacitive sensing variable quantity；Then, as shown in Figure 4 B, when the keycap 10 is pressed and by this first When putting P1 and being moved to a second place P2, then the keycap 10 can press the top surface of elastomer 30 downwards so that the elastomer 30 to Lower deformation, and the cone shaped elastic part 40 also downward compression, now, the cone shaped elastic part 40 produces with the capacitive sensing area 71 The change of spacing is compressed, and its inductance capacitance variable quantity (namely induced electricity capacitance) corresponds to it and presses power, exports a correspondence In the compression signal of this pressing force intensity.

Certainly, Fig. 4 A and Fig. 4 B are only the schematic diagram that the utility model illustrates push action, the change in location of the keycap 10 It is non-to be only limited to first position P1 and second place P2, but the pressing force of the keycap 10 can be pressed with user and make the cone Shape elastic component 40 produces different degrees of compression, and then the keycap 10 is located at different height and positions.

In more detail, when user press the intensity of the keycap 10 it is bigger and when producing larger pressing stroke spacing, The cone shaped elastic part 40 compresses to the capacitive sensing area 71 of the sensor circuit plate 70 and caused pressing force is also bigger, the electric capacity sense The induced electricity capacitance for answering area 71 to sense is also relatively large；That is, the intensity of the induced electricity capacitance and pressing force into Direct ratio.

Because the utility model controls using the power for pressing the power of keycap 10 the induced electricity capacitance of output, can apply In in general input through keyboard, computer is set to perform different orders because of its induced electricity received capacitance size；Such as：In word During input, when pressing keyboard P bonding forces road is smaller, it inputs the p for small letter, and when pressing P bonding forces road is larger, then input is The P of capitalization.

As shown in figure 5, it is second embodiment of the present utility model, the bottom surface group of its sensor circuit plate 70 is provided with a hair Optical assembly 90, and the luminescence component 90 is LED light source, its light source is by the one of the middle position of sensor circuit plate 70 Perforation 72, and the keycap 10 of printing opacity is produced efficiency limpid in sight, even if the keycap 10 obtains the effect of illumination and printing opacity extremely should The top surface of keycap 10.

In summary, this creation produces different compression signals using the compression degree of the cone shaped elastic part, and then According to pressing power control output signal, to perform the function of different command.
