Abstract
The utility model relates to a frame type touch screen protective hood, consisting of a glass sound wave touch screen, four Y and Z axial receiving and sending reflective stripes which are arranged at the four edges of the touch screen, four Y and Z axial receiving and sending transducers. The four reflective stripes and the four transducers which are positioned on the sound wave touch screen are covered by the four touch screen embedding elements of the plastic or metal square frame type dust protective hood on the four edges of the sound wave touch screen, thereby isolating the reflective stripe and the transducer from outside, preventing dust from depositing on the transducer and the reflective stripe of the touch screen so as to avoid the dust from seriously interfering and influencing the precision and the performance of the touch screen, with easy mounting and using capability.
Description
The utility model relates to a kind of corollary apparatus of computer screen display technique, particularly a kind of frame-type touch-screen protective cover.
At present touch screen technology also is in developing stage in the world, and in China, 8.4 " above surface acoustic wave touch screen technology only has a company to grasp the large-scale production technology in Sichuan.Touch screen technology is used very extensive, as: the inquiry of public information: as the service inquiry of departments such as telecommunications, the tax, bank, insurance, electric power, the data check in the flight at airport, station, train query, museum, the Art Museum, library; Be applied to public telephone equipment for surfing the net, network POS terminal, leader's office, Industry Control, military commanding, electronic game, choosing song or selecting dish, multimedia teaching, real estate sale or the like in addition.
Existing touch-screen, screen the body upper left corner and the lower right corner have been fixed one respectively vertically and the ultrasound transmitting transducer 4 of horizontal direction, and two corresponding ultrasound wave receiving transducers have then been fixed in the upper right corner.Four peripheries of screen body then are carved with miter angle by dredging to the point-device reflection strip 2 of close spacing.With the Y-axis is example, and transmitting transducer YS is the electrical signal conversion that is produced by controller that ultrasonic energy sends.Transducer designs makes it have narrower deflection and propagates acoustic surface wave energy left, in the transmittance process, upwards be reflected into the even face propagation of the perpendicular direction of screen surface again by base 45 degree reflection strips 2, gathered into line to the right by the reflection strip 2 of top again then and be transmitted to Y-axis receiving transducer YS, and finally transfer electric signal to and penetrate the signal plug by the transmitting-receiving of cable and transducer and be transported to controller.
When not touching, the waveform of received signal is with just the same with reference to waveform.When the finger touch screen, finger a part of acoustic wave energy, controller then detects received signal in the decay at certain a moment, can calculate the position of touch point on Y-axis thus, same principle can obtain the position of the X-axis of touch point, as shown in Figure 1.The X that can respond except general touch-screen, the Y coordinate, surface acoustic wave touch screen also responds its 3rd exclusive Z axial coordinate, just can perception user touch pressure sizes values.Its principle is that the damping capacity by the receiving signal attenuation place calculates.Three in case determine that controller is just passed to main frame to them.Because surface acoustic wave is highly stable, and the controller of surface acoustic wave touch screen comes calculated touch location by measuring the position of attenuation initiation on time shaft, so surface acoustic wave touch screen is highly stable, precision is also very high.
But a big weakness of surface acoustic wave touch screen is afraid of dust exactly.Because said above, the sensitivity of surface acoustic wave touch screen is very high, if dust accretions on the transducer 4 and reflection strip 2 of touch-screen, can serious precision and the performance of disturbing and influencing touch-screen, sometimes even can not work.
The purpose of this utility model is to disclose and a kind ofly can makes the emission striped not disturbed by dust and influence, thereby can guarantee the acoustic wave touching screen operating accuracy, guarantees whole complete machine service property (quality) and the frame-type touch-screen protective cover of being convenient to install.
The technical scheme that frame-type touch-screen protective cover is adopted is:
Adopt plastics or metal quadro frame shape dust cover 3, on similar the same four limits that are embedded in acoustic wave touching screen 1 mutually with frame, four touch-screen inserts of quadro frame shape dust cover 3 cover four reflection strips 2 on the acoustic wave touching screen 1 and transducer 4, it is fixedly connected with four touch-screen inserts of dust cover 3 to re-use connecting elements 5, make reflection strip 2 and transducer 4 with extraneous hide every.As Fig. 1, shown in Figure 5.
Press from both sides frame 3.2 after adopting dust cover fore-clamp frame 3.1 and dust cover, with screw that forward and backward dust cover folder frame is fixedly connected, after fixedly connected the getting well of forward and backward dust cover folder frame, identical with the size of dust cover 3, promptly be embedded in mutually on four limits of acoustic wave touching screen 1, quadro frame shape dust cover 3 covers four reflection strips 2 on the acoustic wave touching screen 1 and transducer 4, make reflection strip 2 and transducer 4 with extraneous hide every.As Fig. 2, shown in Figure 6.
Two kinds of the built-in type of described dust cover 3 and front and back folder frames, the wiring of abandoning " P " of built-in type is fixing with connecting elements 5, and the nothing of the front and back folder frame wiring " P " of abandoning is screwed.
Have plastics or metal dust cover mounting hole 6 on the described dust cover 3, be convenient to installing and fixing of whole touch screen.
Advantage of the present utility model is:
1, avoided surface acoustic wave touch screen to be afraid of a big weakness of dust.Avoid dust accretions on the transducer and reflection strip of touch-screen, can seriously disturb and influence the precision and the serviceability of touch-screen, make the operate as normal of touch-screen that assurance arranged.
2, touch-screen 1 is embedded in the dust cover 3 mutually; make reflection strip and transducer be hedged off from the outer world, make the emission striped not disturbed by dust and influence, and obtain well protection; even when sweeping the clean-up dust, also can guarantee acoustic wave touching screen precision and service property (quality).
3, the science owing to the simple in structure of dust cover 3 of the present utility model, very convenient when using installation, effect is obvious.
The utility model is described in further detail below in conjunction with description of drawings and embodiment.
