The invention discloses a noise reduction type interior trim panel for a high-speed train. The interior trim panel comprises a bottom plate, the left side of the bottom plate is connected with one ends of a plurality of second sound insulation frames which are arranged at equal intervals, the other ends of the second sound insulation frames are connected with the left side of a sound insulation layer, a plurality of first sound insulation frames and third sound insulation frames which are arranged at equal intervals are arranged on the right side of the sound insulation layer, an interior trim panel is arranged on the right side of each first sound insulation frame, and several sound absorption panels are placed in the first sound insulation frames, the second sound insulation frames, and the third sound insulation frames in a penetrating mode. According to the automobile interior trim panel, the structure is simple, the design is novel, the structural strength of the interior trim panel is improved, the overall weight is reduced through a honeycomb-shaped three-dimensional hollow structure, noise in an automobile is reduced through the arrangement of the sound insulation layer and the sound absorption panels, the sound insulation and noise reduction effects and the comfort of the whole vehicle are improved, the honeycomb-shaped three-dimensional hollowed-out sound absorption panels effectively absorb sound of all frequencies, meanwhile, a heat dissipation effect is achieved, and the service life is longer.

    本发明公开了高铁列车用减噪型内饰板,包括底板,底板的左侧与若干个等距排列的第二隔音架的一端相连,第二隔音架的另一端均与隔音层的左侧相连,隔音层的右侧设有若干个等距间隔排列的第一隔音架、第三隔音架,第一隔音架的右侧设有内饰板,第一隔音架、第二隔音架、第三隔音架内均贯穿放置若干个吸声板,本装置结构简单,设计新颖,提高了内饰板的结构强度,蜂窝状立体镂空结构减轻了整体的重量,设置隔音层、吸声板降低了车内的噪音,提高了隔音降噪效果和整车的舒适性,蜂窝状立体镂空的吸声板有效吸收各个频率的声音,同时起到散热的效果,使用寿命更长。
