Description
Technical field
The present invention relates to a kind of Trackpad (touchpad), particularly about a kind of Trackpad that can inducing switch button sense.
Background technology
Therefore Trackpad is widely used on each electronic product because volume is little, cost is low, consumed power is low and long service life, and for example notebook computer, mouse, MP3 player, mobile phone or the like even are as input media.Known Trackpad has three kinds of resistance-type, electromagnetic type and condenser types.Resistor type touch control plate need utilize nib application of force on minimum area when operation, the electromagnetic touch-control plate need cooperate the special pen with battery to import, and with regard to performance and cost, capacitive touch control plate surmounts resistance-type and electromagnetic touch-control plate.The principle of work of capacitive touch control plate is the moment of utilizing object to touch Trackpad to produce a capacity effect, thereby can determine the object position contacting by the variation of capacitance, therefore, capacitive touch control plate must be by the input pen of electric consumption unlike the electromagnetic touch-control plate, the use of capacitive touch control plate also needs compression point to concentrate unlike resistor type touch control plate, so serviceable life is longer.Moreover the composition of capacitive touch control plate is simple, and element is few, and the product percent of pass height makes that cost was lower when capacitive touch control plate was produced in a large number.
The mode of operating capacitance touch plate has many, and modal is to touch on its surface or slide with finger or pen, so that the inductor in the Trackpad produces corresponding signal.Inductor is a device that includes one dimension or two-dimentional sensor conductor, and normally the etching trace forms on printed circuit board (PCB), and its structure has four layers, double-deck, and individual layer, and the principle of sensing article is identical haply.In order to protect inductor and effect attractive in appearance; be coated with the level and smooth insulant of one deck on the inductor; its material is generally based on insulating gel and plastic cement shell; for example with reference to plane Trackpad shown in Figure 1 and curved surface Trackpad shown in Figure 2; coverture 12 on inductor 10 has the effect of insulation; and have level and smooth surface and allow user's finger touch thereon and slide, but structure reference example " the object position sensor " that proposed for No. 5374787 as the United States Patent (USP) of awarding to Miller people such as (Miller) in more detail.
Trackpad can provide considerable function, for example in " Trackpad with scrolling and translation " that the United States Patent (USP) of awarding to history Supreme Being sweet smell people such as (Stephan) is proposed for No. 5748185, definition cursor control zone, scrolling control zone and translation control zone link graphical user's interface (Graphical User Interface; GUI) instruction in or function, and in " spool control device " that the United States Patent (USP) of awarding to Aaron people such as (Allen) is proposed for No. 5943052, the slip of finger on the scrolling control zone of definition sees through the scrolling that processor software is directly controlled window.Trackpad also can be used for analogue-key, to replace mechanical type button (mechanical switch button) in the past, for example with reference to No. the 240050th, the novel patent of TaiWan, China.Yet, when Trackpad is applied to analogue-key, because the insulant that covers on the inductor can not provide the sense of touch when operating machine the formula button, the user can't obtain feedback from finger when the virtual key of operation Trackpad, thereby can't experience pressing and decontroling of button, and can only wait for the response of control system, and do not respond if having, then need heavily come again a push action.Bring many benefits with the Trackpad analogue-key, for example press the bond distance than mechanical type serviceable life, and Trackpad is more not fragile, but the virtual key of Trackpad has the above-mentioned characteristic that is difficult to differentiate for the user.The mechanical type button is a mat application of force extruding button and produce push button signalling, and the operation Trackpad when producing signal the outward appearance of Trackpad there is no any change, therefore above-mentioned difficulty can't overcome.
Therefore, a kind of can inducing switch button sense, provide the user to be very easy to differentiate and use the Trackpad mouth of virtual key function simultaneously, be to be the institute Ji.

Embodiment
Fig. 3 to 5 is schematic perspective views of three Trackpad embodiment.In the Trackpad of Fig. 3, a coverture 14 is arranged on the inductor 10,12 key areas 16 are arranged on the coverture 14, it is the bulge-structure of D that a thickness is arranged on each key area 16.In the Trackpad of Fig. 4, the coverture 18 on the inductor 10 has 12 key areas 20, on each key area 20 sunk structure is arranged, and the thickness of coverture 18 in the sunk structure center is D.In the Trackpad of Fig. 5, it is the coverture 22 of D that a thickness is arranged on the inductor 10, and 12 key areas 24 are arranged on the coverture 22, is planar structure on it.Here alleged key area is meant the zone that will reach the virtual key function on coverture with respect to inductor, is used for allowing the user be used as the zone of button operation, presses on the key area when inductor has detected object, just in response to producing push button signalling.
Fig. 6 to 8 is sectional views of the Trackpad of Fig. 3 to 5, but coverture 14,18 and 22 is all the insulator of deformation, can be out of shape because of external force pressure.With reference to Fig. 9 to 11, when finger pushes button the zone, coverture 14,18 and 22 deforms in key area 26,28 that is pressed and 30 places, make finger near inductor 10, thereby generation push button signalling, after finger was decontroled, coverture 14,18 and 22 restored to the original state again, as shown in Fig. 6 to 8.The feedback impression that coverture 14,18 and 22 deformation produce the user allows the user have to press and decontrol the sensation of button, and inductor 10 also receives the action that the user pressed and decontroled button because of this deformation simultaneously.
Figure 12 to 14 is sectional views of the other embodiment of Trackpad.In Figure 12, have a stilt 32 between inductor 10 and the coverture 14, it has the space 34 that a degree of depth is D below key area 16.In Figure 13, have a stilt 32 between inductor 10 and the coverture 18, it has the space 34 that a degree of depth is D below key area 20.In Figure 14, have a stilt 32 between inductor 10 and the coverture 22, it has the space 34 that a degree of depth is D below key area 24.Shown in Figure 15 to 17, when finger pushes button the zone, coverture 14,18 and 22 in the key area 36,38 that is pressed and 40 places deform and fill in the space 34, make finger near inductor 10, thereby produce push button signalling.After finger was decontroled, coverture 14,18 and 22 restored to the original state again, as shown in Figure 12 to 14.In these three embodiment, stilt 32 is an insulator, and coverture 14,18 and 22 is insulator or conductor.In certain embodiments, the very thin thickness of stilt, it does not have the space below the key area.The effect of protection inductor only merely is provided.
When these Trackpads of operation, the user need just not know whether via the response of control system and finish the action of pressing and decontrol button, can be directly from feedback sensation that obducent alteration of form provided and learn whether oneself is through finishing the input of button.With level and smooth surperficial different of past Trackpad, the structure of making on the coverture key area allows the user can be very clearly and easily find and operation push-button, particularly when using night.
Figure 18 is the vertical view of Trackpad, the figure that has the expression button on each key area 44 of coverture 42, this figure can be the plane, for example be printed on surface, key area 44 or be attached on the key area 44, also can be three-dimensional, for example pattern that on key area 44, moulds or uneven surface.
Except the flat shape of aforementioned each embodiment, Trackpad also can be made curve form, and as shown in figure 19, inductor 10 is curved surfaces with coverture 22, and can form the bulge-structure or the sunk structure of previous embodiment on the key area.
Figure 20 is the graph of a relation between the capacitance change Δ C that produces of obducent deformation quantity Δ D and inductor.When the key area was not pressed, coverture did not deform, so capacitance change Δ C is zero.When the key area is pressed when dark more, obducent deformation quantity Δ D is big more.That is point more near inductor, so capacitance change Δ C is big more, shown in curve 46.C1 represents to produce the critical value of push button signalling, its correspondence according to pressing depth be D1.When the depth delta D that is pressed when the key area surpassed critical value D1, inductor just produced push button signalling.The size of adjusting critical value can be adjusted the sensitivity of button, and for example critical value setting is that the Trackpad of C2 is than the easier triggering push button signalling of the Trackpad that is set at C1.Obducent pliability also influences the sensitivity of button, and for example soft coverture just surpasses critical value D1 and produces push button signalling under less pressure.The running of relevant inductor is a known technology, can utilize hardware, software or firmware to reach.
Coverture can use gummed, screws togather, chimeric or alternate manner is fixed on and answers on device or the stilt.Trackpad with Fig. 3 is an example, and as shown in figure 21, adhesive agent 48 is coated on around the surface of inductor 10, thus gummed coverture 14 and inductor 10.Trackpad with Figure 12 is an example, and as shown in figure 22, mat screw 50 is solid on stilt 32 with coverture 14 spiral shells in four corners of Trackpad.Trackpad with Figure 14 is an example, and as shown in figure 23, there is projection 52 coverture 14 belows, on stilt 32 and the inductor 10 embedded hole 54 are arranged, and mat pushing projection 52 is fixed on coverture 14 on the stilt 32 to embedded hole 54.In certain embodiments, it is removable covering a lid thing, for example changes the coverture with different key figure or structure for the position that Trackpad is applied in different button of simulation or transposing key area.Change the sensitivity that softer or harder coverture can change button.Use removable coverture to have extra advantage.For example can renew during dirty or scratch at it.
Though Trackpad of the present invention utilizes obducent deformation to produce the sensation of button, the shortcoming that does not but have the mechanical type button, for example Jing Mi electrical contact point, remove spring (debouncer) mechanism and mechanical abrasion etc., therefore, the present invention obtains the advantage of Trackpad and mechanical type button simultaneously, has but lacked the shortcoming of mechanical type button.
