Abstract
The utility model discloses an interdigital transducer windscreen wiper device, including supersonic generator, the last interdigital transducer who installs on the windshield that is connected with of supersonic generator. The utility model discloses can the more effective rainwater of driving away windshield, make the effect of driving away the rainwater better.
Description
Technical field
The utility model relates to Wiping device.
Background technology
Vehicle in the process of moving, keep away and unavoidably run into rainy day, when rainwater is fallen after on Windshield, if disposing not in time, the sight line of chaufeur will be affected, there is larger potential safety hazard, for rainwater can be disposed timely, past and even be all now adopt wiper rubber device to realize, this mode has continued many years, also there is no a kind of device can removing rainwater in actual use at present, and when present wiper motion is frequent, can affect the sight line of chaufeur yet.
Therefore, the structure adopting other mode to substitute existing wiper has been described in some document, be in the patent documentation of 2013.8.21, disclose a kind of super sonic wiper as be 201320077564.6 applyings date in Chinese Patent Application No. being 2013.2.18 authorized announcement date, and specifically disclose and comprise Windshield, hot-air system, ultrasonic vibrator, rain sensor.When raining, automatically start ultrasonic vibrator and hot-air system by rain sensor, rain is vibrated into tiny raindrop by ultrasonic vibrator, blows raindrop off completely by hot-air system.Although this structure changes the mode of traditional removal rainwater, be difficult to blow raindrop off by hot-air system, remove the poor effect of rainwater.
Summary of the invention
In order to the more effective rainwater exorcising Windshield, allow and drive away the better effects if of rainwater, the utility model provides a kind of interdigital transducer Wiping device.
For achieving the above object, a kind of interdigital transducer Wiping device, comprises ultrasonic generator; Ultrasonic generator is connected with the interdigital transducer be installed on Windshield.
Said structure, interdigital transducer can produce horizontal table ground roll, and the particle at dielectric surface during lateral surfaces wave traveling does elliptic motion; Oval long axis normal is in surperficial direction of wave travel, and minor axis parallel is in surperficial direction of wave travel, and the elliptical vibration of medium particle can be considered the synthesis of compressional wave and shear wave.Horizontal table ground roll runs into surface rain water in communication process, then part ultrasonic surface wave is converted into leaky wave pattern list ground roll, and by certain angle to emittance in drop, thus drive the flowing of rainwater.Therefore, the hypracoustic horizontal table ground roll utilizing interdigital transducer to produce changes the moving direction of windscreen surface attachment, and the surface attachments such as the dirt of rainwater, separation, the foreign material of separation are expelled Windshield, improves the effect of driving away rainwater.
Further, the interdigital transducer of more than two is installed on the top of Windshield or bottom.In general, the lateral dimension of Windshield is greater than longitudinal size, the interdigital transducer of more than two is transversely arranged, when fork value transducer works, horizontal table ground roll drives rainwater to move downward or upward, reduce the travel of rainwater at Windshield, can rainwater be allowed faster to leave Windshield.
Further, mucigel is provided with between interdigital transducer and Windshield.Convenient firm, failure-free fixation fork finger transducer.
Further, the connection lead between ultrasonic generator and interdigital transducer is along the edge placement of perspex.In order to avoid connection lead affects the sight line of chaufeur.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1, interdigital transducer Wiping device comprises ultrasonic generator 1; Ultrasonic generator 1 is connected with the interdigital transducer 3 be installed on Windshield 100 by connection lead 2.
Connection lead 2 is arranged in the edge of Windshield 100, prevents connection lead 2 from disturbing the sight line of chaufeur, improves safety performance.
The interdigital transducer 3 of more than two is installed on the top of Windshield 100.In general, the lateral dimension of Windshield 100 is greater than longitudinal size, the interdigital transducer of more than two is transversely arranged, when fork value transducer 3 works, horizontal table ground roll drives rainwater to move downward, and reduce the travel of rainwater at Windshield, and rainwater itself has gravity, under the effect of self gravitation, rainwater can be allowed faster to leave Windshield 100.
Mucigel is provided with between interdigital transducer 3 and Windshield 100.Convenient firm, failure-free fixation fork finger transducer 3.
In the present embodiment, interdigital transducer 3 can produce horizontal table ground roll, and the particle at dielectric surface during lateral surfaces wave traveling does elliptic motion; Oval long axis normal is in surperficial direction of wave travel, and minor axis parallel is in surperficial direction of wave travel, and the elliptical vibration of medium particle can be considered the synthesis of compressional wave and shear wave.Horizontal table ground roll runs into surface rain water in communication process, then part ultrasonic surface wave is converted into leaky wave pattern list ground roll, and by certain angle to emittance in drop, thus drive the flowing of rainwater.Therefore, the hypracoustic horizontal table ground roll utilizing interdigital transducer 3 to produce changes the moving direction of windscreen surface attachment, and the surface attachments such as the dirt of rainwater, separation, the foreign material of separation are expelled Windshield, improves the effect of driving away rainwater.
