Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Among the utility model embodiment, layout has the touch key-press position on the panel of electronic equipment, be distributed with at least two induction electrodes on the substrate of the induction installation of key panel below, combination of electrodes when touching detection based on mutual capacitance with formation, wherein, the relative position of these at least two electrodes and shape can be provided with flexibly.
Fig. 2 A shows the cross-sectional view of touch key-press induction installation in the electronic equipment that the utility model first embodiment provides.For convenience of description, only show the part relevant with the utility model.
With reference to Fig. 2 A, key panel 202 is used to bear the push action of finger 201, and key panel 202 belows are pasted with the touch sensible parts substrate 205 of having arranged induction electrode.Be distributed with circular outer ring electrode 203 above the touch sensible parts substrate 205 and be positioned at inner and isolated with outer ring electrode 203 central electrode 204 of outer ring electrode 203, the position relation of outer ring electrode 203 and central electrode 204 is shown in Fig. 2 B.Touch sensible parts substrate 205 is generally printed circuit board (PCB), and (Printed Circuit Board, PCB), this moment, outer ring electrode 203 and central electrode 204 were exactly this wiring above pcb board.Central electrode 204 is connected on the main control board 208 by electric conductor 206, and 203 of peripheral electrode are connected on the main control board 208 by flexible conductor 207.In the present embodiment, electric conductor 206 is selected metal spring for use.Touch sensible parts substrate 205 is close to the inner face of panel 202 when considering installation, spring meeting pressurized generation deformation, and correspondingly, lead 207 is selected the soft wire rod of quality for use, and keeps necessary latitude on the length.Metal spring 206 plays dual parts resiliency supported material and electric conductor simultaneously in this embodiment.If adopt other idioelectric elastomeric materials to do support, central electrode 204 still adopts flexible conductor 207 with being connected of main control board 208.
Further, making the electrode of circle or annular into other symmetric figure can't the appreciable impact effect. and therefore, the wiring of outer ring electrode 203 and central electrode 204 also can be adopted other symmetrical shape, the octangle shown in Fig. 2 C sometimes.
Sometimes consider special panel material or the installation site relation of adapting to, or touch the detection principle of control chip,, need sometimes the locus of induction electrode is placed on the different aspects in order to obtain best detection effect according to difference.Fig. 3 shows a kind of distressed structure of first embodiment, and wherein, central electrode 204 is positioned at the lower floor of peripheral electrode 203, keeps certain vertical range.Fig. 4 shows the another kind of distressed structure of first embodiment, and wherein, central electrode 204 is positioned at the upper strata of peripheral electrode 203, keeps certain vertical range equally.In the distressed structure of these two first embodiment, because central electrode 204 is on the different aspects with peripheral electrode 203, therefore, can suitably dwindles the peripheral electrode size or enlarge the central electrode size, it is overlapping to allow them to have in vertical direction, and then obtains best detection effect.In this case, the composition that forms on vertical plane of the electrode that distributes on the different aspects is symmetrical.Also it may be noted that, in the time of necessary, in order to allow the electrode on two aspects keep certain vertical range, two electrode aspects can be arranged in and not be on the same substrate, that is to say, can insert the polylith substrate between two electrode aspects or allow and leave the space between the substrate.
Fig. 5 shows the section projection structure figure of the induction electrode unit of touch key-press induction installation in the electronic equipment that the utility model second embodiment provides, and for convenience of description, only shows the part different with first embodiment.Present embodiment comprises three electrodes, and the quantity of increase outer ring electrode can realize the function that some are specific better, for example near detecting identification human body touch, wet rag and water covering or the like situation.
Fig. 6, Fig. 7 and Fig. 8 show the cross-section structure of the induction electrode unit of touch key-press induction installation in the electronic equipment that the utility model the 3rd embodiment provides, and for convenience of description, equally only show the part different with first embodiment.The absolute electrode of peripheral electrode circle with a plurality of circles (Fig. 6) or other shapes (Fig. 7, Fig. 8) replaced, form the array that is symmetrically distributed around central electrode, also can realize the function that some are specific preferably, for example near detecting situations such as identification human body touch, wet rag and water covering.
Be to be understood that, the various embodiments described above all beyond the electrode position relation that comprises central electrode be described, the shape of each electrode and the relation of position each other are not limited to this during concrete enforcement, as long as the two or more electrodes with clearance for insulation are set.
Because the touch of mentioning here detects the detecting that all is based on for mutual capacitance between the electrode, and the approaching or touch of the relative panel of human finger causes that the mutual capacitance between the induction electrode changes just, touches the detection control circuit and can judge the appearance of touch action by detecting this capacitance variations.And in fact, except that human body, other materials, water for example, the position that appears at touch button device also can cause the variation of mutual capacitance between the electrode, causes that just the characteristics of variation are different.Therefore, utilize the touch key-press induction installation that the utility model proposes, can also be used for detecting the amount of liquid of panel surface well.The application of a conversion of its these characteristics is exactly as a kind of rain sensor, is used to equip the automatic wiper device on the automobile.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
