1. The utility model provides a structure of making an uproar falls for automobile body sheet metal component cavity which characterized in that:

  • the noise reduction structure comprises an expansion rubber block assembly arranged in a cavity of a sheet metal part of an automobile body, the expansion rubber block assembly divides the cavity of the sheet metal part into a plurality of cavities, the surface of the expansion rubber block and the cavity of the sheet metal part are arranged along the cross section of a horizontal plane horizontally or in an included angle, an insertion part fixed with a process hole of the surface of the sheet metal part is arranged on the expansion rubber block, a gap for electrolyte to pass through is arranged between the expansion rubber block assembly and the sheet metal part, and/or a process hole for the electrolyte to pass through is arranged on the expansion rubber block assembly;

    the automobile body sheet metal part is an automobile A column (10), an A column expansion rubber block (10A) is arranged at the middle section position of the automobile A column (10) in the length direction, the peripheral outline of the plate surface of the A column expansion rubber block (10A) is arranged to be matched with the outline of the cavity section of the automobile A column (10), a fabrication hole (11) is formed in the A column expansion rubber block (10A), and an inserting part (12) fixed with the automobile A column (10) is arranged at the edge of the A column expansion rubber block (10A);

    the length direction of A post inflation gluey piece (10A) face and car A post (10) is perpendicular, and the edge of A post inflation gluey piece (10A) is laminated with the internal face of car A post (10), and fabrication hole (11) are waist shape and interval and are provided with two, still be provided with on A post inflation gluey piece (10A) with spacing post (111) that the inboard face of car A post (10) leaned on, grafting portion (12) are the elasticity non return plug of gluing piece (10A) edge for setting up at A post inflation, and elasticity non return plug constitutes the grafting cooperation with the fabrication hole that sets up on car A post (10).
