The invention discloses a coaming reinforcing structure, a vehicle body coaming and a vehicle, the coaming reinforcing structure comprises a framework and a foaming piece, the foaming piece is arranged on the framework, the framework is fixed in a concave part of the coaming sunken towards an air window component, the shape of the framework is matched with the shape of the concave part, and the foaming piece is arranged on the framework. The space between the framework and the inner wall of the concave part is filled with the foaming part after foaming, the framework is provided with a stopping part, the stopping part is used for preventing the foaming part from overflowing out of the framework when the foaming part is foamed, and a gap is formed between the end, close to the air window component, of the framework and the end, close to the air window component, of the surrounding plate. The concave part is provided with a first side wall corresponding to the inclined surface of the air window component, and a first gap is formed between the foaming piece and the first side wall before the foaming piece is foamed. The supporting rigidity of the air window component can be enhanced, shaking of the air window component is reduced, and the NVH performance is improved.

    本发明公开了一种围板加强结构、车身围板及车辆,其中围板加强结构包括骨架和发泡件,所述发泡件设置在所述骨架上,所述骨架固定在围板向风窗部件凹陷的凹入部内,所述骨架的形状与所述凹入部的形状相适应,所述发泡件发泡后填充在所述骨架与所述凹入部内壁之间,所述骨架上设有止挡部,所述止挡部用于阻止所述发泡件发泡时溢出所述骨架,所述骨架靠近所述风窗部件的一端与所述围板靠近所述风窗部件的一端之间设有间距,所述凹入部具有与所述风窗部件的倾斜面对应的第一侧壁,所述发泡件未发泡前,所述发泡件与所述第一侧壁之间设有第一间隙。本发明能够加强对风窗部件的支撑刚度,降低风窗部件的抖动,提升NVH性能。
