The side air curtain can be arranged between the A column and the B column, so that the side air curtain can impact the upright post decorative plate after being detonated. The inventor designs an air bag buckle device (patent number 201420382296.3), which comprises a clamp seat and a buckle, wherein the clamp seat comprises an insertion part, a base and a fixed seat, the insertion part is arranged below the base and is inserted into an automobile fixing piece so as to be fixed, the fixed seat is arranged on the base, clamping grooves are arranged on the front side and the rear side of the fixed seat, and an insertion hole is arranged in the middle of the fixed seat; the clamping buckle comprises a clamping buckle seat and a clamping piece, wherein the clamping piece is arranged on the clamping buckle seat, the bottom of the clamping buckle seat is provided with an insertion rod, the clamping body is arranged twice in the front and at the back of the clamping buckle seat, during assembly, the insertion rod is inserted into an insertion hole, and the clamping body is embedded into a clamping groove, so that the clamping buckle is detachably connected onto the clamping seat.
However, the buckle of the airbag buckle with the structure is completely fastened with the matched automobile fixing piece, and the disassembly is laborious and the structure of the automobile body is easily damaged if the buckle is repaired or the like; and the air bag belt with the structure is formed by injection molding, so that the problems of low strength, high cost, easy breakage under the huge impact force of air bag blasting and the like exist.
Therefore, the inventor also designs a safety buckle of the side air curtain of the automobile, which comprises a first buckle and a second buckle, wherein a connecting rope is arranged between the first buckle and the second buckle, and two ends of the connecting rope are respectively detachably arranged on the first buckle and the second buckle; the first buckle comprises a clamping part, an insertion rib and a first connecting column; the clamping part is suitable for clamping the upright post decorative plate to fix; the inserting rib is fixedly arranged above the clamping part, a metal buckle is arranged on the inserting rib, the metal buckle is clamped and fixed on the inserting rib, and the first buckle is inserted into the automobile sheet metal through the metal buckle for fixing; first spliced pole fixed set up in the clamping part below, first spliced pole is the mushroom, connect rope one end twine in fix on the first spliced pole. Compare and compare current gasbag buckle, this scheme can only trade partial subassembly when needs, reprocess more convenient and save the cost.
However, this car side air curtain safety buckle has the not firm problem of metal buckle installation, and first buckle separates with the metal buckle easily, makes it have the possibility that drops from the car panel beating. In addition, the connecting rope needs to stretch into the upright post decorative plate for internal installation, and the problem of inconvenient installation exists.
Therefore, how to improve the existing safety buckle of the side air curtain of the automobile so as to overcome the above disadvantages is a problem to be solved urgently by those skilled in the art.
Disclosure of Invention
The invention aims to provide a safe buckle component of a side air curtain of an automobile, which is convenient to mount and dismount and is firmly mounted.
In order to achieve the above purposes, the technical scheme adopted by the invention is as follows: a safety buckle assembly of an automobile side air curtain comprises a first buckle and a second buckle, wherein the first buckle is suitable for fixedly connecting an automobile metal plate and an upright post decorative plate, and the second buckle is suitable for being fixedly arranged on the automobile metal plate; a connecting rope is arranged between the first buckle and the second buckle, and two ends of the connecting rope are detachably arranged on the first buckle and the second buckle respectively; the method is characterized in that:
the first buckle comprises a clamping part, an inserting part and a first connecting column; the clamping part is suitable for clamping the upright post decorative plate to fix; the first connecting column is fixedly arranged above the clamping part, the first connecting column is in a mushroom shape, and one end of the connecting rope is wound on the first connecting column for fixing; the insertion part is provided with an installation groove, and a metal buckle is installed in the installation groove;
the metal buckle comprises an A-shaped spring piece, and a first connecting piece, a second connecting piece, an upper limiting piece and a lower limiting piece are symmetrically arranged on two sides of the A-shaped spring piece; the A-shaped spring piece can deform towards the middle; the first connecting piece is fixedly arranged at the lower end of the A-shaped spring piece, and the first connecting piece inclines towards the middle from top to bottom; the second connecting piece is fixedly arranged at the lower end of the first connecting piece, the second connecting pieces on two sides are suitable for entering the mounting groove, when the metal buckle is in a natural state, the second connecting pieces are slightly inclined towards two sides from top to bottom, and when the metal buckle is mounted on the insertion part, the second connecting pieces tend to be in a vertical direction; the first connecting sheet and the second connecting sheet are sunken towards the middle to form a groove, and the groove is suitable for clamping the metal buckle in a mounting hole of the automobile sheet metal; go up the spacing piece with spacing piece from top to bottom sets up in on the second connecting plate, go up the spacing piece with spacing piece extends to both sides down, is suitable for the centre gripping the inserted part.
