The schematic diagram of portion's explosion；Fig. 3 is the schematic diagram that confined explosion is switched in Fig. 2；Fig. 4 is the explosive view switched in Fig. 2；Fig. 5 is Fig. 3
The sectional view of X-X along middle switch；Fig. 6 is sectional view of the switch when press section that it triggers bracket is pressed in Fig. 5.First
The press-key structure 1 of embodiment includes keycap 12, bottom plate 14, elevating mechanism 16 and switch 18.Bottom plate 14 is set to 12 lower section of keycap.
Elevating mechanism 16 is arranged in correspondence between bottom plate 14 and keycap 12, and keycap 12 can be relative to bottom plate 14 via elevating mechanism 16
It moves up and down.In this present embodiment, elevating mechanism 16 is scissors foot support, is connected to keycap 12 and is set to its 122 following table of cap body
Connection structure 124 and bottom plate 14 on face are set to the connection structure 144 of its 142 upper surface of plate body；But the present invention not as
Limit, such as with the telescoping mechanism or two bracket implementation elevating mechanisms being provided separately of cantilever design, the cannula-like structure that changes.It opens
It closes 18 and includes pedestal 182, fixed magnetic absorption member 184, triggering bracket 186, conducting bracket 188, the first electric terminal 190 and the second electricity
Gas terminal 192.Pedestal 182 is fixedly installed on 12 lower section of keycap relative to bottom plate 14.In this present embodiment, pedestal 182 is directly solid
Due on plate body 142, such as pedestal 182 is embedded to the groove or opening being formed on plate body 142, and or pedestal 182 to stick together
Mode is fixed on plate body 142 with fixing piece (such as screw, coupler construction).Fixed magnetic absorption member 184, the first electric terminal
190 and second electric terminal 192 be fixedly installed on pedestal 182.Triggering bracket 186 and conducting bracket 188 are rotatably arranged
In on pedestal 182.Triggering bracket 186 has press section 1862, the first magnetic part 1864, first end 1868 and the first pushing portion
1866, bracket 186, which is triggered, with first end 1868 is rotatablely connected with pedestal 182.Press section 1862 protrudes from pedestal 182 and sets
12 lower section of keycap is set and be located at, generates the first magnetic attraction F1 (with double-head arrow between the first magnetic part 1864 and fixed magnetic absorption member 184
It is shown in Fig. 5 and Fig. 6).Be connected bracket 188 have contact portion 1882, the second magnetic part 1884 and the second pushing portion 1886 and
The second end 1888, contact portion 1882 are oppositely arranged with the first electric terminal 190, and bracket 188 is connected with the second end 1888 and is
Fulcrum is in be rotatably connected with pedestal 182.The second magnetic attraction F2 is generated between second magnetic part 1884 and fixed magnetic absorption member 184
(being shown in Fig. 5 and Fig. 6 with double-head arrow), the first pushing portion 1866 are oppositely arranged with the second pushing portion 1886.
Wherein, in principle, the torque that the first magnetic attraction F1 generates triggering bracket 186 is greater than the second magnetic attraction F2 to conducting
The torque that bracket 188 generates, therefore as shown in figure 5, when press section 1862 is not pressed (such as not pressed by keycap 12), first
Magnetic attraction F1 drives the fixed magnetic absorption member 184 of triggering 186 rotation direction of bracket, so that triggering bracket 186 is supported via the first pushing portion 1866
The second pushing portion 1886 is pushed away so that the fixed magnetic absorption member 184 of conducting 188 whiz of bracket makes contact portion 1882 far from the first electrical end
Son 190；In other words, the first electric terminal 190 and the second electric terminal 192 do not turn on (or meaning is not electrically connected), that is, switch
18 are not triggered.Also, as shown in fig. 6, when keycap 12 towards bottom plate 14 it is mobile to press press section 1862 when (such as 12 quilt of keycap
User's pressing causes 122 following table face contact of cap body and presses down on press section 1862), triggering bracket 186 by external force (i.e. pair
The pressing force of press section 1862) it restrains, the first magnetic attraction F1 is overcome by the external force, the fixed magnetic absorption member of triggering 186 whiz of bracket
184, the second magnetic attraction F2 drive the second pushing portion 1886 of conducting bracket 188 persistently to abut the first pushing portion 1866, conducting branch
188 rotation direction of frame fixes magnetic absorption member 184.
When press section 1862 is pressed into setting position (as shown in Figure 6), contact portion 1882 contacts the first electric terminal
190 to be connected the first electric terminal 190 and the second electric terminal 192, and the first pushing portion 1866 is supported with the second of conducting bracket 188
Pushed section 1886 is initially separated；In other words, the first electric terminal 190 and the second electric terminal 192 conducting (or meaning is electrically connected), also
I.e. switch 18 is triggered.When renewing downward push press section 1862, the first pushing portion 1866 divides completely with the second pushing portion 1886
From；By the structure of switch 18 it is found that the contact force that contact portion 1882 contacts the first electric terminal 190 at this time depends on the second magnetic
Power F2, unrelated with the pressing force that press section 1862 is arrived, therefore, each contact portion 1882 contacts the first electric terminal 190 in principle
Contact force it is all the same, therefore can reach protection contact (electric terminal 190,192) the effect of.In addition, being opened shown in supplementary explanation Fig. 6
18 state is closed, wherein contact portion 1882 has contacted the first electric terminal 190, and the first pushing portion 1866 still contacts second and supports
Pushed section 1886, but triggering bracket 186 may continue to be pressed and continue to rotate clockwise and cause the first pushing portion as seen from the figure
1866 are kept completely separate with the second pushing portion 1886, therefore Fig. 6 is only for display triggering bracket 186 in from state up time shown in fig. 5
During needle rotates (because being pressed), when not pressed completely, i.e., contact portion 1882 can be made to contact the first electric terminal
190, eventually to when being pressed completely, natural energy is kept completely separate the first pushing portion 1866 with the second pushing portion 1886, and contact portion
1882 keep being kept in contact with the first electric terminal 190 by the second magnetic attraction F2.
In addition, the first magnetic attraction F1 drives the fixed magnetic of triggering 186 rotation direction of bracket when the external force for pressing keycap 12 disappears
Part 184 simultaneously pushes the fixed magnetic absorption member 184 of conducting 188 whiz of bracket so that contact portion 1882 far from the first electric terminal 190 (also
That is the first electric terminal 190 and the second electric terminal 192 are not turned on), and press section 1862 is moved up to drive keycap 12 to return
To original position；In other words, the first magnetic attraction F1 is also driving keycap 12 to return to original position at this time, or the first magnetic attraction F1 also conduct of meaning
The restoring force of keycap 12.In addition, in this present embodiment, when contact portion 1882 contacts the first electric terminal 190 so that the first electricity is connected
When gas terminal 190 and the second electric terminal 192, the first pushing portion 1866 and the separation of the second pushing portion 1886, this can ensure that contact
Portion 1882 contacts the first electric terminal 190, but is not limited in practical operation, such as based on triggering bracket 186 and conducting
Still there is a degree of cantilever spring characteristic in 188 structure of bracket, it can be suitably designed so that the first pushing portion 1866 and the
Two pushing portions 1886 must be still kept in contact when contact portion 1882 contacts the first electric terminal 190.In addition, when triggering bracket 186
And when conducting 188 equal gold mining category structure fabrication of bracket, aforementioned cantilever spring characteristic can be become apparent from.Also, in this present embodiment, conducting
The contact portion 1882 of bracket 188 and the second pushing portion 1886 are relative to the second magnetic part 1884 (or second end of conducting bracket 188
Portion 1888) for, it also can be considered separated cantilever design, therefore mutually pushed in the first pushing portion 1866 and the second pushing portion 1886
When, the gearing between contact portion 1882 and the second pushing portion 1886 can also introduce the elastic deformation amount of cantilever design, this is based on general
Cantilever beam theory and will appreciate that, do not repeat separately.
In addition, in this present embodiment, pedestal 182 is hollow structure, and it includes upper cover 1822 and lower seat 1824, upper covers 1822
It is connected (such as being connected by buckle, card slot) formation accommodating space 1826 with lower seat 1824.Upper cover 1822 and lower seat 1824 clamp
Fixed magnetic absorption member 184.Triggering bracket 186 is set to through-hole of in accommodating space 1826 and its press section 1862 from upper cover 1822
1822a stretches out upper cover 1822 (or meaning pedestal 182), first end 1868, the first pushing portion 1866 and first towards keycap 12
Magnetic part 1864 is then located in accommodating space 1826.Conducting bracket 188 is set in accommodating space 1826.First electric terminal
190 and second electric terminal 192 (such as clamp and/or be embedded to lower seat 1824 via upper cover 1822 and lower seat 1824 and project
Mode and be fixed on lower seat 1824) from accommodating space 1826 stretch out pedestal 182.Thereby, pedestal 182, which can provide, accommodates in it
Component protection, also provide a degree of dust-proof effect to electric terminal 190,192, facilitate between electric terminal 190,192
The maintenance of conducting resistance also facilitates the service life of lifting switch 18.In practical operation, the effect of pedestal 182 is not to protect
Shield, it is dust-proof be limited, therefore even if pedestal 182 is made with frame structure, it is only necessary to which it has structure of fixed magnetic absorption member 184, supplies
