The invention provides an encircling type expansion rubber block, and relates to the technical field of automobile NVH. The encircling type expansion rubber block comprises an expansion rubber block main body, bending plates and a fixing buckle, the expansion rubber block main body comprises a fixing framework and EVA, the EVA wraps the surface of the fixing framework, the bending plates and the fixing framework are integrally formed, and the bending plates are located on the two sides of the fixing framework; and each bending plate is provided with a concave part facilitating bending of the bending plate, and the fixing buckle is connected with the surface of the fixing framework through a connecting plate. By arranging the bending plates, the technical problem that the expansion rubber block cannot be arranged when a metal plate is flanged is effectively solved, and the blocking requirement when the metal plate is flanged is met on the premise that the sensory feeling of passengers in the front row is effectively improved.
本发明提供了一种环抱型膨胀胶块,涉及汽车NVH技术领域,包括膨胀胶块主体,弯折板以及固定卡扣,所述膨胀胶块主体包括固定骨架以及EVA,所述EVA包覆在固定骨架的表面,所述弯折板与固定骨架一体成型且位于固定骨架的两侧,所述弯折板上设有便于弯折板进行弯折的凹陷部,所述固定卡扣通过连接板与固定骨架的表面相连。通过设置弯折板使有效的解决有钣金翻边时无法布置膨胀胶块的技术难题,在有效提高前排乘客感官感受的前提下,解决了有钣金翻边时封堵需求。
