Wherein, above-mentioned two thimble structures position grouping in an array and the key assignments one_to_one corresponding of button.
The core concept of technical solution of the present invention is that different button cap structures has uniqueness with the key assignments of this button and associates, particularly, the thimble structure of general structure is coordinated in firm banking, by the screening of button cap isolation structure, select the position grouping of a certain group of thimble structure, and array scanning circuit below conducting button, accordingly, conduction position and the button value of array scanning circuit also have one-to-one relationship, processor is according to the conduction position of this array scanning circuit, find the corresponding relation with key assignments, such as look-up table, identify this button value.By changing different button caps, the button of this position can be made to have the button value corresponding with button cap structure, completes redefining button value based on this technical scheme.
The press-key structure of remote controller and the identifying of button value in embodiment is introduced in detail below in conjunction with figure.
As shown in Figure 2, remote controller comprises pcb board 1, and multiple button 3.
The corresponding each key position of silastic-layer be positioned at above pcb board 1 all forms a silicon rubber frame 21, silicon rubber frame bottom tilts to the inside, for producing certain resilience force when silicon rubber frame is subject to downward extruding, make, during user's pressing keys, there is certain feel.
On remote controller, each button 3 comprises a button cap 31 and a firm banking.Wherein, firm banking comprises silicon rubber frame 21, and multiple thimble structure 4.This multiple thimble structure 4 is arranged in array, and does not limit concrete array formation at this, but structure based volume and compactedness are considered, array arrangement is preferably square formation.
Thimble structure 4 is made up of conductive material, such as metallic iron, copper etc., and this multiple thimble structure shape size is consistent, and thimble structure array in each button firm banking is all identical, as general part, easy to process.One end of these thimble structures 4, is fixed on pcb board 1.In one embodiment, as shown in Figure 3, thimble structure also has a public pedestal 41, and pedestal 41 is also made up of electric conducting material, therefore multiple thimble structure and pedestal can be used that identical electric conducting material is one-body molded to be made.
The corresponding each thimble structure 4 of pedestal 41 lower surface is also respectively arranged with the conductive contact 42 of projection, and this conductive contact is as the extension of thimble structure.Thimble structure 4 is fixed on pcb board 1 with welding manner by the conductive contact 42 of pedestal 41 upper process.
Equally as shown in Figure 3, on pcb board 1, corresponding each key position place is evenly equipped with the array scanning circuit 11 corresponding with above-mentioned multiple thimble structure array, this array scanning circuit 11 is also general performance circuit structure, facilitate the printing fabric swatch of pcb board, wherein Fig. 4 A is the circuit theory diagrams of this array scanning circuit, be divided into horizontal scanning line and column scan line, every bar horizontal scanning line and column scan line are all connected to processor.Above-mentioned conductive contact 42 is multiple, and as the electrode of array scanning circuit 11, can by array scanning circuit turn-on, as shown in Figure 3, conductive contact 42 can be welded on the electrode pad place of array scanning circuit 11.Array scanning circuit 11 is made up of M bar horizontal scanning line and N bar column scan line, wherein M and N sum equals the sum of thimble structure in each described thimble structure array, and M thimble structure and M bar horizontal scanning line all have the line number of 1 to M, remaining N number of thimble structure and N bar column scan line have the column number of 1 to N, wherein M, N are the integer being greater than 1.
In one embodiment, thimble structure 4 array arrangement schematic diagram as shown in Figure 4 B, the array arrangement arranged in 3 row X3 for 9 thimble structures 4, horizontal scanning line and the column scan line quantity sum of array scanning circuit also equal 9.Preferably, array scanning circuit ranks that are capable with M=5 and N=4 row are arranged, form 20 crosspoints at most like this, can certainly be that 4 row 5 arrange, it should be noted that, the combination meeting M and the N of M+N=9 has multiple, but the crosspoint formed due to the horizontal scanning line of array scanning circuit and column scan line can not be less than the number summation of thimble structure, otherwise cannot all thimble structures of one_to_one corresponding thimble structure array, if i.e. M=8, N=1 then only has 8 crosspoints, can not satisfy condition.Therefore, when selecting M and N combination, mostly comparatively being good with the crosspoint of array scanning circuit, namely choosing the combination of M and N value larger in the product of M and N.
These horizontal scanning lines and 6-9 is given respectively to these column scan lines numbering respectively with 1-5,9 thimble structures also have the numbering of 1-9 simultaneously, the thimble structure wherein with a numbering and the horizontal scanning line with identical numbering or column scan line corresponding, such as be numbered the thimble structure corresponding row scan line 1 of 1, be numbered the thimble structure respective column scan line 6 of 6.
Array scanning circuit 11 on the pcb board 1 that each button is corresponding is arranged also identical, and the line of these array scanning circuit same positions numbering is all in parallel, and is connected to a pin input port of processor IC.As shown in Figure 5, the horizontal scanning line being numbered 1 in such as all push-button array scanning circuits is connected in parallel, and be connected to pin 1 place of processor IC, in like manner, all horizontal scanning lines being numbered 2 are connected in parallel and are connected to pin 2 place of processor, by that analogy, all column scan line parallels being numbered 9 together and be connected to pin 9 place of processor.
The shape of button cap 31 can sheet or tabular, is the tabular of rounded square in the present embodiment.
The usual silk-screen of button cap 31 upper surface or be pasted with label, facilitates user to identify the button title of this button.As shown in Figure 6A, button cap 31 lower surface is coated with conductive layer 311, and this conductive layer can be metal level also can be graphite linings.Button cap 31 lower end is also provided with isolation structure parts, and this isolation structure preferably adapts with button cap shape, and be the spacer 312 of square sheet, this spacer 312 is connected to button cap lower surface by bonding way, namely bonds on conductive layer 311.Spacer is that non-conductive material is made, and can be such as resin, can certainly be silicon rubber, plastic material.Spacer 312 can stop the contact of some thimble structures and conductive layer 311, and allows other thimble structures and conductive layers make contact, to thimble structure 4 by playing screening effect.
In one embodiment spacer 312 has perforate, spacer 312 perforate schematic diagram as shown in Figure 6B, number identical with thimble structure array is offered and hole corresponding to position near the one side of thimble structure array at spacer, and only have two in this some holes for through hole, lay respectively at the position of the first row first row, reference numeral is the thimble structure of 1, and be positioned at the tertial position of the third line, reference numeral is the thimble structure of 6, all the other are blind hole (representing with black circles in figure), and the position of opening of through hole is uniquely determined by the key assignments of button.
When button cap is pressed, as shown in Figure 6A, button cap 31 moves down, two through holes in spacer 312 only allow in multiple thimble structure 4 be arranged in array, two thimble structures that position is corresponding with it, are that numbering 1 and 6 is passed respectively, and contact with the conductive layer 311 of button cap lower surface, remain 7 thimble structures and insert blind hole, can not spacer be penetrated thus cannot conductive layer be touched.Like this, the combination of spacer 312 vias position is determined by the key assignments of button, lead to the hole site determines again the position grouping of the thimble structure that can play conducting effect, thus the position grouping of two thimble structures that button value and spacer filter out has one-to-one relationship.For example, key assignments " A " may correspond in Fig. 4 and is numbered 1, and the thimble structure position grouping of 6 is corresponding, the thimble structure position grouping of key assignments " B " reference numeral 2,8, those skilled in the art's easy understand, key assignments A herein, B is only citing, does not represent actual button value.
Now, two thimble structures through through hole utilize the conductive layer touched, the electric conductivity of self, and conductive contact is by the array scanning circuit turn-on of pcb board, thus send the signal of telecommunication to processor, follow-up processor of introducing how according to signal of telecommunication key range key assignments, and performs corresponding function.
And when button is not pressed, above-mentioned two thimble structures completely by the through hole of spacer, can not still keep a segment distance with the conductive layer of button cap lower surface, cannot contact, thus can not array scanning circuit on conducting pcb board.
Above-mentioned spacer structure can also offer groove by the lower surface at button cap, groove inner surface applying conductive coatings, and spacer structure embeds in groove, or spacer can be fixed together with button cap by screw etc. and to be connected.The size of spacer is less than or equal to the size of button cap usually, and thickness is less than the thickness of button cap.
What the spacer structure of above-mentioned button cap is realized to the process need explanation of thimble structure position grouping screening is, choose the incompatible unique corresponding key assignments of set of locations of two thimble structures, higher as conductive media reliability than being used alone a thimble structure on the one hand, important Consideration is simultaneously, the compound mode of two thimble structures is very many, may correspond to multiple key assignments.
And, also mention above, on remote controller, the thimble structure array of multiple button is all general part mutually, different key-value pairs answers the different position groupings that can play two thimble structures of conducting effect, embody in the spacer structure of button cap, the combination of two lead to the hole site that this spacer structure is offered is different.
Same for the thimble structure array of the 3X3 shown in Fig. 4 B, the thimble structure of 9 kinds of Position Numbers, utilizes mathematical combination principle, can realize at most 36 kinds of combinations, in theory can corresponding 36 kinds of key assignments, so remote controller utilize this structure can arrange at most 36 kinds of buttons.Those skilled in the art can understand, the species number of key assignments as required can select the number of thimble structure, such as, if need the key assignments of more than 40 kinds, so according to combinatorial principle, then at least need 10 thimble structures, because these 10 thimble structure combination of two, 45 kinds of key assignment combination can be realized.
The process that button value is identified is described in detail below in conjunction with Fig. 5 and Fig. 6.When button A is pressed, the thimble structure 4 being numbered 1 and the thimble structure 4 being numbered 6 pass the through hole of correspondence position on spacer and touch conductive layer 311, the horizontal scanning line being numbered 1 is communicated with the column scan line being numbered 6 with 6 by the conductive contact 1 that thimble structure is corresponding, thus be numbered the horizontal scanning line of 1 and be numbered column scan line electrode place's conducting of 6, form path.The pin 1 of processor and pin 6 place receive the signal of telecommunication of conducting, it can be such as high level signal, processor judges the signal from which two pin, thus determine the key assignments content of the combination correspondence of these two pins, wherein the combination of pin and the corresponding relation of key assignments can write processor in advance, and processor is known with lookup table mode.
When button is not pressed, although the thimble structure 4 being numbered 1 and 6 inserts through hole, not completely by conductive layer 311 can not be touched, array scanning circuit 11 corresponding below it also would not be started.
Thus, because of the structure of button cap, the namely choice structure of spacer, uniquely can reflect button value, select the PCB circuit of thimble structure conducting below it of diverse location combination, key assignments also uniquely can be reflected in the position that on pcb board, array scanning circuit is switched on, if to when the button base in somewhere installs different button caps, so the button value at this place is also just redefined along with button cap structure is different.
Next the removable process realizing button cap is introduced by reference to the accompanying drawings.
In an embodiment of the present invention, button cap is connected removably with firm banking, and specific implementation can be: be provided with magnetic element in button cap inside and firm banking, this magnetic element can be ferrimagnet, such as magnet.

As shown in Figure 8, button cap 31 is the sheet made of silica gel or resin material or plate body, and its inside has space can embed magnet piece 6 or iron block.It should be noted that magnet piece or iron block avoid touching the conductive layer of button cap lower surface as far as possible, in order to avoid when forming galvanic circle, magnet piece or iron block or ferrimagnet may produce interference to galvanic circle.
As shown in Figure 2, in order to realize detachable connection, firm banking also comprises a support 5, this support 5, as magnetic element, is in particular the bearing structure of magnet piece 6, and this support bottom snaps in silicon rubber frame 21 opening part, the resilience force of silicon rubber frame is utilized to be clamped, support 5 upper extending wall is taken in silicon rubber frame wall along upper, or supporting structure also can be socketed and silicon rubber edge edge lower end, utilizes the resilience force of self and silicon rubber frame to clamp.
Support 5 top caves inward formation groove structure, and for holding magnet piece 6, in order to prevent magnet piece from coming off from support, magnet piece does not generally protrude from support, and shape and the groove of magnet piece adapt.Simultaneously, to be fixed on pcb board 1 because of thimble structure 4 one end and to stretch out in silicon rubber frame 21 and close with button cap 31, therefore this support 5 is preferably hollow frame structure, allow thimble structure array to extend there through, now rack groove can be an annular or racetrack continuous print groove, and this is relevant with the shape of support, such as support is circular, an annular groove may be formed, also can be rounded square, racetrack groove may be formed.Accordingly, the magnet piece in groove, preferably, can adapt with the global shape of groove, be also hollow structure.
Certainly, this magnet piece 5 can be a complete hollow structure, also can be multiple little magnet piece, be distributed in the groove of support, and correspondingly, the groove in support is also multiple, and along support perimeter distribution, does not limit at this.
Because the size of magnetic attraction is relevant with the contact area of two the magnetic element parts attracted each other, therefore the magnet piece that is embedded in of button cap or iron block, preferably, corresponding with the magnet piece position in rack groove, and contact with the acting surface of maximum area as far as possible, button cap and firm banking are fixed together by magnetic attraction by both.
As shown in Figure 8, one that provides for the embodiment of the present invention complete press-key structure assembly drawing.Wherein, thimble structure 4 one end is fixed on pcb board 1, and successively through the silicon rubber frame 21 above pcb board 1, support 5, is positioned at the magnet piece 6 on support 5, and inserts in the spacer 312 of button cap 31 lower end.Wherein, the key-press shell 7 on remote controller body, for fixed support 5, prevents support 5 and magnet piece 6 from coming off from silicon rubber frame 21, ensures firmness and the reliability of whole press-key structure.
Magnet piece in button cap 31 or iron block (not shown in Fig. 8) are fixed by magnetic attraction is attracting with the magnet piece 6 on support 5.
In order to make the convenient disassembly of button cap, in one embodiment as shown in Figure 2, button cap 31 side is provided with breach 313, special instrument can be used or lever up device and in indentation, there, button cap be levered up gently with certain active force, taken off by button cap, the button being positioned at marginal position can be taken off by this mode levered up, also can along sliding in outward direction, make the magnetic attraction suffered by button cap more and more less, complete dismounting.When installing button cap, above the base that only button cap need be placed in this button, just can easily button cap be adsorbed onto on firm banking by magnetic attraction.
In another embodiment, other ferrimagnets can be filled with in button cap inside, such as iron powder.Magnet piece installed by the support of firm banking, realizes fixing by magnetic attraction between button cap and firm banking.
Above-described embodiment is by arranging magnetic element respectively by button cap and button base, magnetic principle is utilized to be linked together by these two structure members, remote controller housing can be destroyed on the one hand and affect other press-key structures and just can realize the button cap of single button and being separated of button base, achieve the detachable of press-key structure.
Simultaneously, compared with the connected mode of carrying out adopting clamping of buckle draw-in groove etc. tangible with two parts, technical solution of the present invention decoration structure features simple design, do not relate to syndeton when dismantling, such as buckle, disassembling of the structural member that draw-in groove etc. are tangible, can not produce physical damage to syndeton, improves the reliability standard that parts connect.
embodiment two,
The embodiment of the present invention and above-described embodiment one difference are, provide the mode that removably connects of another button, facilitate user taken off from firm banking by button cap or install.
In the present embodiment, button cap is connected with the detachable mode of firm banking, specifically can make: connected by an elastomeric element.Elastomeric element can be spring, and spring members structural design is simple, and owing to having certain retractility, the pressing feel of button can be better.Wherein, spring one end can overlap in the upstanding portion of the silicon rubber frame opening part of access firm banking, or silicon rubber frame upstanding portion outwards turns down in the turnover part of formation and the gap of upstanding portion, or and the spring other end can snap on button cap, in the protrusion of such as button cap bottom surface, this protrusion has limit rib or rotates helicitic texture, and what produce after can preventing or weaken spring snapping rocks.Button cap can depart from from spring upper end using of certain force, realize being separated of button cap and button base, thus button cap is detachable.
Because thimble structure need run through multiple parts, therefore the internal diameter of spring members is larger than the catercorner length of thimble structure square formation, and thimble structure stretches out from silicon rubber frame successively, through spring members inside, and inserts in the spacer of button cap lower end.
When pressing keys cap, spring is compressed, and two thimble structures touch the conductive layer of button cap, and conduction array scanning circuit completes the identification of key assignments.
In above-described embodiment two, there is thimble structure and spacer equally, the array scanning circuit of button value can be reflected according to the selection index system conducting of button cap, corresponding button value is determined according to the conduction position of array scanning circuit by processor, its operation principle and detailed process, with embodiment one, do not repeat them here.
And, in order to realize detachable connection, its connection scheme also can be: described button cap has buckle structure, key-press shell has draw-in groove, by button cap and button can between buckle and draw-in groove coordinate and realize being connected, when key-press shell will be dismantled, only need to apply with certain active force, make buckle generation deformation, deviate from from draw-in groove.
