Description

静音汽车内饰板
技术领域
本发明设计一种内饰板,具体涉及一种静音汽车内饰板,属于汽车内饰技术领域。
背景技术
目前,汽车内饰板的生产工艺大致有如下几种:1、注塑成型;2、PP 材料、棉板、木
粉板以及麻纤维板模压成型;3、PU 发泡成型。这几种材料及所使用的工艺、技术都有各自的技术缺陷:首先,注塑成型;塑料粒子从石油当中提取,属重化工、重污染产业,其原材料本身能耗及成本很高,且是一种不可再生资源;塑料多次回用后的废弃物在自然环境中很难降解,人类对注塑的过量使用必然对环境产生破坏(俗称白色污染);其次,PP 材料、棉板、木粉板以及麻纤维板模压成型;这三种材料都是天然不可再生材料,受自然条件限制,棉、麻、木材生长周期较长。最后,PU 发泡成型;采用这种技术PU 用料大,废弃物不可回收,在自然环境中也很难降。此外,现有的汽车内饰板隔音效果不理想。
发明内容
为了解决上述问题,本发明提供了一种静音汽车内饰板,结构简单、设计合理,设计了四层结构,且在前后两层设计双层隔音板,创新地设计了隔音板的结构,将隔音板设计为基座和基座上的横向设置的三棱柱结构的消音条,第二隔音板包括自下而上依次设置的第一基座、以及第一基座上设置的若干行第一隔音块组,第一隔音块组包括自左至右依次设置的第一隔音条、第二隔音条;大大提高了产品的隔音效果,自重轻,环保安全。
本发明的目的是通过以下技术方案实现的,一种静音汽车内饰板,其特征是,设有第一饰板本体、第一隔音板、支撑层、第二隔音板、第二饰板本体,第一饰板本体、第一隔音板、支撑层、第二隔音板、第二饰板本体自上而下依次设置,所述第一隔音板包括自下而上依次设置的基座、以及基座上设置的若干个消音条,消音条为横向设置的三棱柱结构;
第二隔音板包括自下而上依次设置的第一基座、以及第一基座上设置的若干行第一隔音块组,第一隔音块组包括自左至右依次设置的第一隔音条、第二隔音条;第一隔音条、第二隔音条之间设有U形槽,第一隔音条、第二隔音条均为横向设置的四棱柱结构,第一隔音条的厚度大于第二隔音条的厚度。
优选的,所述第一饰板本体由玻纤毡和PU 材料构成,PU 材料喷涂在玻纤毡上发泡成型而成。
优选的,所述第二饰板本体由玻纤毡和PU 材料构成,PU 材料喷涂在玻纤毡上发泡成型而成。
优选的,所述支撑层为铝箔。
优选的,所述隔音板为聚氨酯材料。
与现有技术相比,本发明具有以下益效果:
第一,本发明结构简单、设计合理,设计了四层结构,且在前后两层设计双层隔音板,创新地设计了隔音板的结构,将隔音板设计为基座和基座上的横向设置的三棱柱结构的消音条,第二隔音板包括自下而上依次设置的第一基座、以及第一基座上设置的若干行第一隔音块组,第一隔音块组包括自左至右依次设置的第一隔音条、第二隔音条;大大提高了产品的隔音效果,自重轻,环保安全。
第二,本发明四层结构中在前后两层各设计了由玻纤毡和PU 材料构成的第一内饰板、第二内饰板,在内饰板的玻纤毡上喷涂PU 材料,PU 定量、定点喷涂提高材料利用率,减少耗用PU 原料,有利于环境保护。
第三,本发明支撑层采用铝箔,使得汽车内饰板的自重降低,实现零件轻质化,有利于汽车节能减排。
