The invention relates to the technical field of automobile plate engineering, and discloses an automobile plate sealing folded edge and an edge folding method. The sealing structure comprises an inner plate, an outer plate, edge folding glue and sealing glue. The outer plate comprises a bottom plate and a bent plate connected with the bottom plate, a cavity is formed between the bottom plate and the bent plate and comprises a first wall, a second wall and a third wall, the inner plate is inserted into the cavity, and the first wall and the second wall are connected with the inner plate through edge folding glue; a sealant connected with the inner plate is arranged at the end part of the bent plate; the inner plate, the third wall and the sealant jointly define a vent hole, and the vent hole is communicated with external air. By adjusting the distance between the coating position of the edge folding glue and the bent plate, the edge folding glue after the edge folding glue is bent does not make contact with the sealant, then the vent hole is formed, gas, close to the sealant, in the folded edge can be directly exhausted to the air through the vent hole after being heated, and therefore glue bubbles cannot be generated on the sealant.

    本发明涉及汽车板材工程技术领域,公开了一种汽车板材密封折边及折边方法。其包括:包括内板、外板、折边胶和密封胶;所述外板包括底板以及与所述底板连接的弯折板,所述底板与弯折板之间具有腔体,所述腔体包括第一壁,第二壁和第三壁,所述内板插入所述腔体,所述第一壁和第二壁通过折边胶与所述内板连接;所述弯折板的端部设有与所述内板连接的密封胶;所述内板、第三壁和密封胶三者共同围合形成通气孔,所述通气孔与外部空气连通。通过调整折边胶的涂覆位置与弯折板之间的距离,使得这边弯折后的折边胶不与所述密封胶接触,进而构成通气孔,折边内部的靠近密封胶的气体在受热之后可以直接由通气孔排向空气,因而密封胶上不会产生胶泡。
