The existing detachable connection modes of the cavity section aluminum profile in the field of automobile bodies mainly comprise the following steps: firstly, a first connecting cavity aluminum profile is pressed into a blind rivet nut, a second connecting cavity aluminum profile is drilled with a through hole and then is connected by screwing a bolt, the connecting mode is that the profile pressed into by the blind rivet nut has the requirement on the thickness of a pressed wall, the wall thickness cannot be too thick, and the technical cost is that the nominal diameter of the existing blind rivet nut is generally smaller than 12mm, so that the connecting method can only be used in the occasion with low requirement on the connecting strength, the number of the blind rivet nuts is required to be increased, the labor hour and the material cost are increased undoubtedly, and the blind rivet nut is provided with a boss on the connecting surface, so that the complete joint connection of the two pieces is influenced, the blind rivet nut is required to be overcome, and the surface of the piece is required to be opened with a counter bore, and the labor hour is increased to increase the cost; secondly, the first and second connecting cavity section aluminum profiles are perforated and welded with smooth through hole sleeves or internal thread sleeves, and then are connected through bolts and nuts, so that the mode can provide higher connecting strength, but the mode still has the defects in several aspects: 1) the welding requirement of the aluminum profile is high, the welding process needs to add a lot of working hours and cost, 2) the strength of materials around the welding line can be reduced by the welding of the aluminum profile, and 3) the connecting matching surface is provided with a bulge, so that the sealing is not facilitated.
As disclosed in chinese patent CN202251344U, a flat head riveting nut, which is a detachable connection mode of an aluminum profile used in the automotive field and is screwed into a workpiece by a bolt, is a common connection mode of flat head riveting nut, and when the nut is used, only the rod part of the nut is pressed into a machined round hole on an assembling surface, a certain connection strength is obtained by friction force, but the head part of the nut is supported on a mounting surface in such a mode, so that a gap with flat head thickness is formed between two connecting pieces, which results in poor sealing effect, and the nut cannot provide a larger connection strength requirement due to limited friction force after being mounted.
