Zusammenfassung: | To provide an optical detection system and a method capable of automatically removing foreign substances.SOLUTION: An optical detection system according to the present invention includes a housing, a transparent protection cover, an optical sensor, a lens module, a sealing material having flexibility and stiffness, and a piezoelectric element. The sealing material has an annular sheet shape, and is provided between the transparent protection cover and the piezoelectric element, and extended and fixed to the housing to seal internal space defined by the housing and the transparent protection cover. The piezoelectric element performs vibration, which is transmitted to the transparent protection cover through the sealing material to remove foreign substances from the transparent protection cover. The present invention not only effectively transmits the vibration and has excellent foreign matter removal performance, but also can achieve effect such as load reduction, power consumption reduction, service life prolongation, and moisture or water leakage prevention.SELECTED DRAWING: Figure 3
【課題】本発明は、異物を自動的に除去できる光検出システム及び方法を提供する。【解決手段】本発明に係る光検出システムは、筐体と、透明保護カバーと、光センサーと、レンズモジュールと、可撓性及び剛性を有する封止材と、圧電素子とを含む。封止材は、環状のシート形状を有し、透明保護カバーと圧電素子との間に設置され、かつ、伸長して筐体に固定されることにより、筐体と透明保護カバーによって規定された内部空間を封止する。圧電素子が振動を行い、前記振動が封止材を介して透明保護カバーに伝送されることにより、透明保護カバーから異物を除去する。本発明は、振動を有効に伝送して優れた異物除去性能を具備することだけではなく、負荷の低減、消費電力の低下、使用寿命の延長、蒸気または水漏れの防止などの効果を達成することができる。【選択図】図3 |
