The invention discloses a dewatering anti-dazzling rearview mirror based on the piezoelectric property. The dewatering anti-dazzling rearview mirror based on the piezoelectric property comprises a fixing base and a threaded sleeve, a mounting hole is formed in the bottom of the threaded sleeve, an adjusting groove is formed in the upper end of the threaded sleeve, a connecting shaft is slidably connected to the inner wall of the adjusting groove, a conveying rod is fixed to the upper end of the connecting shaft, and the conveying rod is fixed to the lower end of the connecting shaft. A mirror table is fixed to the upper end of the conveying rod, a reflective mirror is fixed to the inner wall of the mirror table, a fine adjustment mechanism is arranged in an adjustment groove, a piezoelectric block is embedded in the side wall of the conveying rod, a knocking mechanism is arranged on the side wall of the threaded sleeve, and a propelling cavity is formed in the side wall of the mirror table. The dewatering anti-dazzling rearview mirror has the advantages that by arranging the pressing rod and the piezoelectric block, when the mirror surface of the reflective mirror is wetted to block sight, the pressing rod is pushed to enable the knocking head to impact the piezoelectric block, so that the electrorheological fluid expands, hydraulic oil moves, a sliding block moves to drive a scraper to move, and then scraping cleaning of the mirror surface of the reflective mirror is achieved; therefore, the reflector can remove water and recover the effective reflection effect.
本发明公开了一种基于压电特性的除水防眩目后视镜,包括固定座和螺套,所述螺套的底部开设有安装孔,所述螺套的上端开设有调整槽,所述调整槽的内壁滑动连接有连接轴,所述连接轴的上端固定有输送杆,所述输送杆的上端固定有镜台,所述镜台的内壁固定有反光镜,所述调整槽的内部设有微调机构,所述输送杆的侧壁嵌设有压电块,所述螺套的侧壁设有敲击机构,所述镜台的侧壁开设有推进腔。优点在于:通过设置压杆和压电块,在反光镜镜面沾水阻碍视线时,推动压杆使得敲击头撞击压电块,从而使得电流变液膨胀,引起液压油运动,使得滑块运动带动刮板运动,进而实现对反光镜镜面的刮擦清理,使得反光镜得以除水而恢复有效反射作用。
