Embodiment
What introduce below is some in maybe embodiment of the utility model a plurality of, aims to provide the basic understanding to the utility model.Be not intended to confirm the crucial or conclusive key element of the utility model or limit claimed scope.
For the purpose, technical scheme and the advantage that make the utility model is clearer, the utility model is done further to describe in detail below in conjunction with accompanying drawing.
First embodiment
Fig. 1 is the synoptic diagram of structure of the touching device of expression the utility model one embodiment.
As shown in Figure 1, the touching device that uses in the vehicle-mounted full touch entertainment systems of the utility model mainly comprises: pcb board is a printed-wiring board (PWB) 4; Be arranged on the resistive touch screen 6 of pcb board 4 tops; Be arranged on these resistive touch screen 6 tops and be used for fixing the resistive touch screen fixed bed 2 of this resistive touch screen 6; And surface coating 1.
As shown in Figure 1, surface coating 1 covers said resistive touch screen fixed bed 2 and the pcb board 4 that includes capacitance type touch key 11.Like this, make capacitance type touch key 11 and resistive touch screen 6 constitute one through covering surfaces overlayer 1.
For surface coating 1, preferably adopt transparent material to constitute.This is because adopt under the situation of transparent material formation, can not stop that the user sees through the resistive touch screen 6 that surface coating 1 is seen the below.As transparent material, preferably can adopt PET (polyethylene terephthalate) or glass.PET molecular structure height symmetry has certain crystalline orientation ability, so have higher film forming and become second nature.And PET has good optical property and weatherability, and amorphous PET has the good optical transparency.PET has good abrasion performance frictional property and dimensional stability and electrical insulating property in addition.Equally, glass also has the light transmission and the abrasion performance frictional property of height.
Therefore; Adopting PET material or glass to constitute under the situation of surface coating 1, not only can seek transparency, and can have certain wearing quality; When touch-surface; Even when touching, because PET or glass are hard material, so also be not easy to scratch the touch screen surface because of hard things such as for example nails.
PET film or glass through an integral body form surface coating 1, can bring incorporate sensation to the user.Can on surface coating 1, print necessary symbol, font or sign etc., also can be different through the thickness of printing, reach easy effect.
But, be preferably less than 0.2mm about the thickness of surface coating 1.This is the dimensional requirement that proposes for the sensitivity in the capacitive sensing zone of satisfying capacitance type touch key.Again, surface coating 1 is bonded on resistive touch screen fixed bed 2 and the resistive touch screen 6 through viscous adhesive.
Like this,, there is not the free gap one by one of mechanical type button in the prior art, operates, can realize same operating experience because the covering of surface coating 1 on the surface, can realize incorporate effect.
In the touching device of the utility model, pcb board 4 is provided with the control chip (not shown) of capacitance type touch key 11 (not shown in Fig. 1, that expression is arranged) and capacitance type touch key in Fig. 2.Resistive touch screen 6 is set above pcb board 4, and the user can realize the direct control of content on the screen through resistive touch screen 6.
On the other hand, in the touching device of the utility model, also comprise: be arranged on being used on the said pcb board 4 to capacitance type touch key 11) LED lamp backlight is provided; Be arranged on the top of said pcb board 4 and be positioned at resistive touch screen 6 the below, be used for the LGP of controlling 3 backlight that provides by said LED lamp; Fixed frame 5 is used for fixing structures such as above-mentioned surface coating 1, resistive touch screen fixed bed 2, LGP 3 and pcb board 4; Gib screw 9 is used for pcb board 4, LGP 4 are fixed to said fixing frame 5; And pcb board connecting line 8, be used to derive the various signals of pcb board 4.
For capacitance type touch key 11, the requirement backlight of whole button is even, need be provided with a lot of backlight, if use the LED lamp separately, can cause backlight inhomogeneously, therefore, LED lamp front increased is provided with LGP 3.The effect of LGP 3 is cross sections that the even oriented users of light of the LED lamp of back can be seen.That is to say that the position of LED lamp is arrived the front through LGP 3 with light transmission on the pcb board 4 of the back of LGP 3, present to the user through the surface coating 1 that above-mentioned transparent material constitutes.
Capacitive touch screen button 11 and resistive touch screen 6 in the utility model, have been combined.Following simple declaration is the capacitive touch screen (button) commonly used and the principle of resistive touch screen in the prior art once.
The working method of capacitive touch screen commonly used is following: capacitance type touch key utilizes the resistance of human body to carry out work, and its touch-screen is made up of four layers of compound glass screen, and sticks particulate metal conductive materials of layer of transparent on the surface.When finger touch was on touch-screen, because people's bulk electric field, user and touch screen surface form with a coupling capacitance, for high-frequency current, electric capacity was direct conductor, so finger siphons away a very little electric current from contact point.This electric current flows out the electrode from four jiaos of touch-screens respectively, and the electric current of these four electrodes of flowing through is directly proportional with the distance of pointing four jiaos, and controller draws touch point position information through the accurate Calculation to these four current ratios.
Resistive touch screen working method commonly used is following: the screen body portion of electric resistance touch screen is a multi-layer compound film; By one deck glass or organic glass as basic unit; The surface scribbles the conductive layer (for example ITO film) of layer of transparent, is stamped one deck outside surface above again through cure process, smooth scratch resistant plastic layer.Its inside surface also scribbles one deck ITO, between two conductive layers, has the transparent isolating points of many tiny (less than mils) to separate them.When the finger contact screen; Two-layer ITO comes in contact, and resistance changes, and on X and Y both direction, produces signal; Controller calculates the XY coordinate of contact point according to detected resistance variations; Operate accordingly according to this coordinate, therefore this technology must be to use the hard thing application of force to screen, could obtain the touch-control effect again.
Fig. 2 is the circuit control block diagram of the touching device of expression the utility model one embodiment.
As shown in Figure 2, in a plurality of contacts 11 ' that are dispersed with a plurality of capacitance type touch keys 11 on every side of resistive touch screen 6.The diameter of above-mentioned contact 11 ' is at least more than the 10mm.As shown in Figure 2, a plurality of contacts 11 ' of capacitance type touch key 11 can be the buttons of different shape, the different shape of circle, triangle etc. for example, and a plurality of contacts 11 ' are distributed in around the said resistive touch screen 6.
In the utility model, capacitance type touch key 11 adopts general matrix keyboard control mode.Key information from capacitance type touch key 11 is transferred to main MCU14 through IC2, so that main MCU reacts accordingly.The output signal of resistive touch screen 6 is directly exported to the main MCU14 of control, the operation that comes the senses touch screen through the output terminal of this touch-screen on the other hand.
Touching device that above example has mainly been explained and the car entertainment system that comprises this touching device.Although only the embodiment to some of them the utility model is described, those of ordinary skills should understand, and the utility model can be in not departing from its purport and scope be implemented with many other forms.Therefore, example of being showed and embodiment are regarded as schematic and nonrestrictive, are not breaking away under the situation of liking defined the utility model spirit of each claim and scope enclosed, and the utility model possibly contained various modifications and replacement.
