The invention belongs to the technical field of sound insulation pads, and discloses an automobile sound insulation pad which comprises sound insulation cotton, transparent structures are arranged at the upper end and the lower end of the sound insulation cotton, a shock suppression structure is arranged at one end of each transparent structure, and a sound absorption structure is arranged at one end of each shock suppression structure; short and small fibrous dust in the sound insulation cotton can be effectively reduced through the thin film layer mounted on the outer wall of the sound insulation cotton, so that the emission of the short and small fibrous dust is reduced when the combined automobile sound insulation pad is used, and the situation that the short and small fibrous dust penetrates through the fabric and floats in the air to harm the health of a human body can be effectively avoided; by means of the synthesized shock-proof plate, some poisonous and harmful gas generated in an existing automobile sound insulation pad can be replaced and avoided, harm to a human body is prevented, and the foam layer can effectively absorb noise when the noise passes through the automobile sound insulation pad in the using process of the automobile sound insulation pad, so that the noise reduction effect is achieved.
本发明属于隔音垫技术领域,且公开了一种汽车隔音垫,包括隔音棉,所述隔音棉的上下两端均设有透明结构,每个所述透明结构的一端上均设有抑震结构,每个所述抑震结构的一端上均设有吸音结构;通过安装在隔音棉外壁上的薄膜层可有效减少隔音棉中短小的纤维状粉尘,从而降低组合后的汽车隔音垫在使用时,短小的纤维状粉尘的排放,由此可以有效避免因为短小的纤维状粉尘,穿透面料飘浮于空气中而危害到人体的健康,通过合成的止震板,可替代避免现有汽车隔音垫中产生的一些有毒有害气体,防止对人体产生危害,泡沫层可在汽车隔音垫使用过程中,有效起到对噪声经过汽车隔音垫时进行吸音,起到降噪效果。
