The invention discloses a vibration noise suppression structure for an automobile body structure, which comprises sound-absorbing cotton, inner plates, sound-absorbing holes, shells and extension mechanisms, the extension mechanisms are arranged on the outer sides of the shells, the two shells drive positioning strips to enter the inner sides of positioning grooves of the adjacent shells, and at the moment, the two plates are attached to each other; and then the U-shaped plate is fixed to the two plate bodies, so that the two shells are fixed, and the beneficial effects that the length of the sound absorbing material is adjusted according to the length of a part needing noise of an automobile, material waste is reduced, and production is convenient are achieved.

    本发明公开了一种用于汽车车身结构振动噪声抑制结构,包括吸音棉、内板、吸音孔、外壳和延伸机构,本发明通过设置了延伸机构于外壳外侧,通过将两个外壳带动定位条进入到相邻的外壳的定位槽内侧,此时两个板体相贴合,然后将U型板固定于两个板体上,从而实现两个外壳进行固定,达到了根据需要汽车所制造噪音的部件的长度对吸音材料长度进行调节,降低了材料浪费,便于生产的有益效果。
