The invention discloses an automobile door panel sound absorption structure which comprises a foaming shock absorption layer, a glass fiber flame retardant layer, a heat insulation layer, a hollow sound absorption cavity layer and a resin rubber plate connected with a sound absorption structure installation assembly from outside to inside. The foaming damping layer in the door plate sound absorption structure achieves the damping effect of the vehicle door plate, the glass fiber flame retardant layer achieves the flame retardant effect of the vehicle door plate, the heat insulation layer achieves the heat insulation effect of the vehicle door plate, the sound absorption cavity layer achieves the sound absorption and noise reduction effect of the vehicle door plate, and then the resin rubber plate and the sound absorption structure installation assembly are movably installed. Wherein an upper vortex plate in the sound absorption cavity layer can eliminate noise transmitted into holes, the honeycomb plate at the bottom layer is matched to further improve the sound absorption effect, meanwhile, due to the fact that vortex holes formed in the vortex plate are opened in the upper portion and closed in the lower portion, introduction of external noise can be further blocked, and the sound absorption and noise reduction capacity is improved.

    本发明公开了一种汽车门板吸音结构,自外而内包括发泡减震层、玻璃纤维阻燃层、隔热层、内部中空的吸音腔层及与吸音结构安装组件连接的树脂胶板,通过门板吸音结构中的发泡减震层起到车门板的减震效果、通过玻璃纤维阻燃层起到车门板的阻燃效果、通过隔热层起到车门板的隔热效果、通过吸音腔层起到车门板的吸音降噪效果,而后通过树脂胶板与吸音结构安装组件活动安装,其中,吸音腔层中的上层涡流板能够将传递至孔内的噪声进行消除,配合底层的蜂窝板进一步提高吸音的作用,同时,由于涡流板上设置的涡流孔上开下合能够进一步阻断外部噪声的传入,提高吸音降噪的能力。
