Embodiment
Below in conjunction with accompanying drawing the shield keyboard according to preferred embodiment of the present utility model is described in detail.
Base plate according to the shield keyboard of the utility model preferred embodiment comes from
The keyboard of SK-8845 type band mouse after the button of this type keyboard and shell remove, can obtain being used to implementing the base plate of the shield keyboard of the utility model preferred embodiment.Yet, on common keyboard not, also can be transformed into according to shield keyboard of the present utility model with mouse.
General requirement to above-mentioned base plate is, circuit board 300 is fixed on (as shown in Figure 1) on the base plate 30, and circuit board is provided with the elasticity keycap 310 that triggers push button signalling, can be switched on or switched off button and transmits signal by pressing the elasticity keycap.And additionally, also being provided with piezoelectric ceramic piece 330 on the circuit board 300, this piezoelectric ceramic piece is operated by the button 450 of mouse, thereby finishes mouse function.
Fig. 1 is the sectional structure schematic diagram of shield keyboard, and as shown in Figure 1, shield keyboard mainly comprises barricade 20, is fixed on the base plate 30 below the barricade 20, is fixed on the guide plate 10 above the barricade 20.Wherein barricade 20 is fixed on the opening of shield 70, thereby the closed shield body forms electromagnetic shielding, and particularly, shield 70 comprises shielding body wall 730 and adjoining edge 710 compositions, and adjoining edge 710 is defined for the opening of fixed mask plate 20.Barricade can be welded on the opening, also can be bolted in opening.
Be fixed with waveguide 210 on the barricade 20, particularly, on barricade 20, quantity, the position of the elasticity keycap on the quantity of set waveguide, position and the base plate are corresponding.Certainly, under the situation that is provided with piezoelectric ceramic piece 320 on the circuit board, also be provided with on the barricade waveguide 230 that should piezoelectric ceramic piece 320.In the waveguide 210,230 is waveguide aperture, and it can stop the electromagnetic wave of corresponding frequencies to pass through, thereby obtains the effect of electromagnetic shielding.
An outstanding feature of the utility model shield keyboard is, be provided with the guide plate 10 that is used for button (for example button 410,430) guiding separately at barricade 20, though this does not get rid of the possibility of utilizing existing keyboard guiding mechanism, yet the structure that is arranged so that the utility model shield keyboard of guide plate 10 goes for the keyboard of number of different types.
On the guide plate 10, the quantity of corresponding waveguide and position offer corresponding guide through hole 110, and the waveguide that extends above barricade part promptly is arranged in this guide through hole 110, as shown in Figure 4.Alternatively, the cross section of guide through hole can be rectangle, triangle or other on-circular cross-section.
Introduce another outstanding feature of the utility model shield keyboard below, in the waveguide aperture of each waveguide, be provided with insulating bar 510,530, insulating bar can move up and down, so that press the elasticity keycap downwards.The structure of insulating bar as shown in Figure 6, the one end has the pressure head 533 that diameter increases, the other end has bellmouth 511.This bellmouth is used for engaging with the tapered portion or the pin of button.Here, the tapering of tapered portion and cone pin is very little, because just as the purpose that engages.The typical structure of button as shown in Figure 5, it comprises surface element 435, the guide part 431 that shape matches with guide through hole 110 and insert cone pin 433 in the insulating bar bellmouth.Thereby button can be on the one hand and insulating bar be bonded together, be guiding with the on-circular cross-section guide through hole on the other hand, be unlikely to rock or rotate.
In addition, some button also need satisfy other requirement, requirement such as stability, it is particularly outstanding that this shows in common so-called space bar and since the space bar length-width ratio than other button greatly, therefore, except the guide part corresponding with waveguide is set, guide part can also additionally be set on space bar, certainly, also need to be provided with corresponding guide through hole on the guide plate.Certainly, might on some buttons, not need guiding yet, thereby on such button, then guide part can be set.
Obviously, button drives insulating bar and moves, press the elasticity keycap, thereby finish the basic function of keyboard, and, because barricade has sealed the opening of shield, between the button of button, mouse and elasticity keycap, the piezoelectric ceramic piece by being located in the insulating bar transmission in the waveguide aperture, thereby the electromagnetic wave that the circuit board in shield produces can not let out, and plays the effect of electromagnetic shielding.
The base plate of shield keyboard of the present utility model can be fixed by following fixture, and as shown in Figure 3, this fixture comprises the distance piece that is fixed on the barricade or strutting piece 610, base plate is fixed on latch hook member 630 on the spacer block.The exemplary configurations of spacer block is promptly arranged around the key area as shown in Figure 2 substantially.Spacer block can be fixed on the barricade 20 by being spirally connected or welding, and latch hook member 630 1 ends are screwed onto on the sidewall of spacer block, and the other end is a latch hook portion, latches in the edge of base plate.For stable fixed base plate, can also in base plate, offer through hole, through hole 301,303 etc. for example, and utilize the screw that wears through hole or alignment pin etc. to make base plate relative barricade location and/or fixing.Obviously, through hole 301,303 will be located at the position that can not influence circuit board or functional structure in the base plate.
In addition, the barricade outside also is provided with panel 100, and this panel is fixed on the guide plate, and covers the zone between the button selectively.
Be preferred embodiment of the present utility model only below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes, variation and omission.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
