The invention discloses a sound insulation rubber block structure avoiding motion interference, a movable metal plate is arranged on the outer side of an A column inner metal plate, a foaming bin is arranged between the A column inner metal plate and the movable metal plate, a mounting framework is arranged on the A column inner metal plate in the foaming bin, a first foaming groove is formed in one side of the mounting framework, a second foaming groove is formed in the other side of the mounting framework, first polystyrene foam is arranged in the first foaming groove, second polystyrene foam is arranged in the second foaming groove, a foaming groove is formed in the middle of the mounting framework, and main polystyrene foam is arranged in the foaming groove; according to the invention, the foaming expansion of the polystyrene foam is limited by the three groups of different foaming grooves, and the three groups of independent polystyrene foam structures are matched to realize multi-direction foaming plugging, so that the plugging of a motion interference cavity is realized, the product performance and the cost are well considered, the effect of improving the NVH can be achieved, and the effects of reducing the cost and simplifying the process can also be achieved.
本发明公开一种避让运动干涉的隔音胶块结构,所述A柱内钣金外侧设有活动钣金,所述A柱内钣金与活动钣金之间设有发泡仓,所述发泡仓内A柱内钣金上设有安装骨架,所述安装骨架一侧设有第一发泡槽,所述安装骨架另一侧设有第二发泡槽,所述第一发泡槽中设有第一发泡胶,所述第二发泡槽中设有第二发泡胶,所述安装骨架中部设有发泡槽,所述发泡槽中设有主发泡胶;本发明通过三组不同的发泡槽对发泡胶发泡膨胀的限制,配合三组独立的发泡胶结构可实现多方向发泡封堵,从而达到对运动干涉腔体的封堵,很好的做到产品性能与成本兼顾,既能达到改善NVH的效果,又能做到降低成本,简单工艺的效果。
