The patent of the invention provides a stable noise reduction device for automobile glass. The stable noise reduction device mainly comprises a suction cup, a wedge block, a hard plastic plate and plastic ropes. The wedge block is a soft block which comprises a hollow cavity and has a triangular cross section, bulges are uniformly distributed on the outer surface of the wedge block, and a protruded limiting plate is arranged at the expanded end part of the cross section; the hard plastic plate is inserted into the hollow cavity of the wedge block; two plastic ropes extend out of the suction cup, one plastic rope is connected with the wedge block, and the other plastic rope is connected with the hard plastic plate; the natural length of the wedge block is 2-5 cm, and the natural thickness of the wedge block is 3mm-2cm. The device is attached to glass through the suction cup, the sharp end of the wedge block can be plugged into the gaps between the glass or between the glass and a windowframe through the hard plastic plate, stabilization is achieved, and noise is reduced.
本发明专利提供一种车玻璃稳定减噪装置,主要包括吸盘、楔形块、硬塑板与塑胶绳。楔形块为含中空腔体且横截面呈三角的柔软块,同时外表面有均布凸起且在横截面扩大的端部有突出的限位板;硬塑板穿插在楔形块的中空腔体内;吸盘上伸出两根塑胶绳,一根连接楔形块,另一根连接硬塑板;楔形块自然长度为两至五公分,自然厚度为三毫米至两公分。该装置依靠吸盘附着在玻璃上,可借助硬塑板把楔形块的尖端塞入玻璃间或玻璃与窗框间缝隙中实现稳定并减少噪音。
