Description
【０００１】[0001]
この考案は車両用バックミラーのごときミラーの表面に付着した水滴を超音波 振動を利用して除去する装置に関する。 The present invention relates to a device for removing water droplets adhering to the surface of a mirror such as a vehicle rearview mirror by utilizing ultrasonic vibration.
【０００２】[0002]
従来、降雨中や多湿時季の走行により、バックミラー表面に雨滴が付着したと き、後方の視認が不十分になり、自動車の走行安全性に問題を生ずる。これを防 ぐためミラーの裏面に圧電振動子を取りつけ、この振動子を振動させてミラー表 面を振動させる事によりミラー表面に付着した水滴を霧化除去する超音波雨滴除 去ミラーが提案されている（特開昭 59-8548号、特開昭 62-238149号及び実開昭 63-69646号等）。 Conventionally, when raindrops adhere to the surface of the rearview mirror due to running in the rain or in a high humidity season, the rear view becomes insufficient, causing a problem in driving safety of the vehicle. To prevent this, a piezoelectric vibrator is attached to the back surface of the mirror, and an ultrasonic raindrop removal mirror is proposed that atomizes and removes water droplets adhering to the mirror surface by vibrating this vibrator to vibrate the mirror surface. (JP-A-59-8548, JP-A-62-238149 and JP-A-63-69646).

ところで従来の超音波雨滴除去ミラーは、ミラーの裏面に振動板を介して振動 子を取付け、この振動子を発振器により駆動するものが通常用いられている。発 振器により駆動される振動子としては主にセラミック等の無機圧電材料が使用さ れ、またミラーの裏面に配設して前記振動子の振動をミラー表面に伝達するため の振動板も金属またはガラス等を用いて形成されていた。 By the way, a conventional ultrasonic raindrop removing mirror is usually used in which a vibrator is attached to the back surface of the mirror via a diaphragm and the vibrator is driven by an oscillator. Inorganic piezoelectric materials such as ceramics are mainly used for the oscillator driven by the oscillator, and the diaphragm for transmitting the vibration of the oscillator to the mirror surface by being placed on the back surface of the mirror is also made of metal. Alternatively, it is formed using glass or the like.
【０００４】 しかしながらこのような従来構造のものは、ミラーアッセンブリが大型化して 嵩ばるばかりか、その重量が重くなる傾向があることから、高速走行時にミラー にビビリ振動を生じ易いという問題がある。 一般に、車両の走行中の振動はエンジン回転数に応じて変化するが、高速走行 時（たとえばエンジン回転数5000ｒｐｍ以上）に、ミラーの固有振動周波数帯に 近ずく傾向がある。ミラーは一般に同一剛性では重量が重くなるとその共振周波 数が下がり、軽くすると共振周波数が上がる特性がある。 そこで本考案は、ミラーを軽量化することによりミラーの共振周波数を高くし て、高速走行時の耐振動性を改善し、かつミラー表面に付着した水滴を超音波振 動により霧化除去できるコンパクトな超音波雨滴除去ミラーを提案することを目 的としている。However, such a conventional structure has a problem that chatter vibration is likely to occur in the mirror during high-speed traveling because not only the mirror assembly becomes large and bulky but also its weight tends to be heavy. Generally, the vibration of a vehicle while traveling changes according to the engine speed, but tends to approach the natural vibration frequency band of the mirror during high-speed driving (for example, engine speed of 5000 rpm or more). Mirrors generally have the characteristic that when the weight is the same, the resonance frequency decreases as the weight increases, and as the weight decreases, the resonance frequency increases. Therefore, the present invention is a compact that can reduce the weight of the mirror to increase the resonance frequency of the mirror, improve the vibration resistance during high-speed traveling, and atomize and remove water droplets adhering to the mirror surface by ultrasonic vibration. The aim is to propose a new ultrasonic raindrop removal mirror.

上記目的を達成するために、本考案は、ハウジングの前面開口部に、傾動自在 に支持されるミラーの裏面に、発振器によって駆動される振動子を設けたミラー 水滴除去装置であって、前記振動子を圧電性高分子材料からなるフイルムまたは シートより形成してこれを前記ミラーの裏面に貼り合せたことを特徴とするもの である。 In order to achieve the above object, the present invention is a mirror water drop removing device, wherein a vibrator driven by an oscillator is provided on a rear opening of a mirror that is tiltably supported in a front opening of a housing. This is characterized in that the child is formed of a film or sheet made of a piezoelectric polymer material and is bonded to the back surface of the mirror.

次ぎに本考案の構成を具体的に説明する。図１は本考案の一実施例である車両 用ドアミラーを示す概略正面図、図２は同上要部の拡大断面図である。 符号１は車両に固定されるハウジング、２はハウジングの前面開口部に傾動自 在に支持される板状のミラー（反射鏡ユニット）である。このミラーは、図２に 拡大して示すように、反射膜３を有するガラスパネル４の裏側に、圧電性高分子 フイルム５が接着剤により一体に取り付けられている。 Next, the configuration of the present invention will be specifically described. FIG. 1 is a schematic front view showing a vehicle door mirror that is an embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view of an essential part of the same. Reference numeral 1 is a housing fixed to the vehicle, and 2 is a plate-shaped mirror (reflecting mirror unit) which is tiltably supported in the front opening of the housing. As shown in the enlarged view of FIG. 2, the mirror has a piezoelectric polymer film 5 integrally attached to the back side of a glass panel 4 having a reflective film 3 by an adhesive.
【０００７】 前記圧電性高分子フイルム５の両端には、電極６及び７が一体に形成されてい る。そしてこの電極６と７とにリード線８を介して発振回路９が接続され、これ により圧電性高分子フイルムに電力が印加される。Electrodes 6 and 7 are integrally formed on both ends of the piezoelectric polymer film 5. An oscillating circuit 9 is connected to the electrodes 6 and 7 via a lead wire 8, whereby electric power is applied to the piezoelectric polymer film.
【０００８】 前記フイルムは、電力が入力すると圧電振動を生じるのでミラー２は共振し、 その振動によりミラーに付着した水滴は霧化除去される。When electric power is input to the film, piezoelectric vibration occurs, so that the mirror 2 resonates, and the vibration causes atomization and removal of water droplets attached to the mirror.
【０００９】 圧電性高分子フイルムとしては、例えばポリフッ化ビリニデン（ＰＶＤＦ）の ごとき圧電フイルムが使用できるが、これに限らず圧電性を有する既知のフイル ムまたはシート状高分子材料ならば、いずれも使用できる。As the piezoelectric polymer film, for example, a piezoelectric film such as polyvinylidene fluoride (PVDF) can be used, but not limited to this, any known film or sheet polymer material having piezoelectricity can be used. Can be used.
