Description

引擎盖隔音垫
技术领域
本实用新型涉及一种车用垫子，尤其是涉及一种引擎盖隔音垫。
背景技术
众所周知，汽车引擎盖隔音垫是安装在车头盖钣金下方，因此就要求其具有一定的强度，不能塌陷。一般的引擎盖隔音垫为玻璃棉或再生棉制品。但是，如果要发挥隔热吸音垫的作用，该隔热吸音垫的厚度往往要达到30mm以上，而要达到这个厚度的话则产品的强度就会较差，且安装困难、容易塌陷，从而影响外观。本实用新型的设计目的就是为了既能达到强度要求，又能起到隔音的较好效果。
发明内容
本实用新型主要是针对现有技术所存在的隔音效果不佳、产品强度低、安装困难、容易塌陷等的技术问题，提供一种隔音效果佳、产品强度高、安装简便、防止塌陷的引擎盖隔音垫。
本实用新型的上述技术问题主要是通过下述技术方案得以解决的：一种引擎盖隔音垫，包括垫体，其特征在于所述的垫体由隔音层和吸音层构成，所述的隔音层设置在吸音层上方，所述的隔音层上表面敷设有无纺布层。隔音层采用EVA或PVC塑料材料制造，吸音层是玻璃棉层，无纺布层则主要起到阻止灰尘和美观的作用，由于EVA或PVC层密度较大，能有效阻隔声音，声音经过此隔音层后，一部分被阻隔反射，透过的声音则再次经过吸音层能得到有效吸收，经过这种处理后，吸音层的厚度可大大减少，同时，由于产品型腔变薄，产品强度得以提高。
作为优选，所述的隔音层采用片材材料制造。隔音层采用EVA或PVC制造，其密度较大，能有效阻隔声音
作为优选，所述的吸音层采用海绵材料制造。吸音层可采用玻璃棉层或PU海绵层。
因此，本实用新型具有隔音效果佳、产品强度高、安装简便、防止塌陷等特点。
附图说明
附图1是本实用新型的一种结构示意图。
具体实施方式
下面通过实施例，并结合附图，对本实用新型的技术方案作进一步具体的说明。
实施例1：
如说明书附图1所示，一种引擎盖隔音垫，包括垫体，垫体由隔音层1和吸音层2构成，隔音层设置在吸音层上方，隔音层上表面敷设有无纺布层3。隔音层采用片材材料制造。吸音层采用海绵材料制造。使用者只需将引擎盖隔音垫安装在引擎盖内表面，即可实现隔音效果。
隔音层采用EVA或PVC塑料材料制造，吸音层是玻璃棉层，无纺布层则主要起到阻止灰尘和美观的作用，由于EVA或PVC层密度较大，能有效阻隔声音，声音经过此隔音层后，一部分被阻隔反射，透过的声音则再次经过吸音层能得到有效吸收，经过这种处理后，吸音层的厚度可大大减少，同时，由于产品型腔变薄，产品强度得以提高。

Claims (3)
