Detailed description of the invention
Below in conjunction with specific embodiment, a kind of D column reinforcement plate of the utility model structure is further described.
As shown in figures 1 to 6, a kind of D column reinforcement plate structure, comprises D column reinforcement plate 1, safety belt reinforced plate 2, rear side wall internal panel 6, top cap rear cross beam outside plate 7 and top cover rear cross beam internal plate 10; Described D column reinforcement plate 1 and described safety belt reinforced plate 2 one-body molded, safety strap is fixed on described D column reinforcement plate 1, described D column reinforcement plate 1 top is Y type, described rear side wall internal panel 6 is fixed on the inside of the upper left side of described D column reinforcement plate 1, and the lateral surface of described rear side wall internal panel 6 upper right quarter and the medial surface of described D column reinforcement plate 1 upper left quarter fit tightly; Described top cap rear cross beam outside plate 7 is fixed on the outside of the upper right side of described D column reinforcement plate 1; Described top cover rear cross beam internal plate 10 is fixed on the inside of the upper right side of D column reinforcement plate 1; Described D column reinforcement plate 1 surrounds internal chamber with described rear side wall internal panel 6, top cap rear cross beam outside plate 7 and top cover rear cross beam internal plate 10.Like this, by described D column reinforcement plate 1 and described safety belt reinforced plate 2 one-body molded, decrease welding, improve rigidity, avoid the fatigue cracking caused owing to welding too much; What decrease tail-gate frame fillet place dodges welding breach simultaneously, and the stress decreasing breach is concentrated.D column reinforcement plate 1 top is Y type, and the both sides, top of Y type can be fixed with rear side wall internal panel 6, top cap rear cross beam outside plate 7 and top cover rear cross beam internal plate 10 respectively, and the continuity of rigidity is good, improves the torsional stiffness of D rod structure.The upper right side of described rear side wall internal panel 6 and the upper left quarter of described D column reinforcement plate 1 fit tightly, and fixing-stable, can play common support effect to tail-gate, reduce tail-gate frame deflection, reduce vibrations, improve intrinsic vibration frequency.
See accompanying drawing 1-6, a kind of D column reinforcement plate structure of the present utility model is on the basis of technique scheme, can be: the external stability of described D column reinforcement plate 1 arranges D post assistant reinforcement plate 4, described safety strap be fixedly installed on D column reinforcement plate 1 by described D post assistant reinforcement plate 4.Like this, safety strap can be made to be fixed on D column reinforcement plate 1.Preferred technical scheme can be further: front portion and the described D column reinforcement plate 1 of described D post assistant reinforcement plate 4 are fixed, the outward-dipping extension of postmedian of described D post assistant reinforcement plate 4, the end of described extension is bent to form the cavity 5 of evagination to the inside, and described cavity 5 is provided with the hole can passed for safety strap.Like this, described cavity 5 serves the effect of dispersive stress, avoids stress and to concentrate and on the fixing impact of safety strap; Simultaneously instead of the less and adapter plate of flat structure of size with the increase D post stiffening plate of cavity 5, improve the installation strength of safety strap.Preferred technical scheme also can be further: the external stability of the upper right side of described D column reinforcement plate 1 arranges tail-door hinge support 3, and described tail-door hinge support 3 is in described top cap rear cross beam outside plate 7 and described top cover rear cross beam internal plate 10 and dodges position.Like this, tail-gate can be connected with D column reinforcement plate 1 by tail-door hinge.
See accompanying drawing 5, a kind of D column reinforcement plate structure of the present utility model is on the basis of technique scheme, can be: described rear side wall internal panel 6 and described top cap rear cross beam outside plate 7 are welded and fixed with described D column reinforcement plate 1, described top cover rear cross beam internal plate 10 be spirally connected fixing with described D column reinforcement plate 1.Like this, described rear side wall internal panel 6 and described top cap rear cross beam outside plate 7 are welded and fixed simple possible, convenient operation with described D column reinforcement plate 1, and cost is low.Described top cover rear cross beam internal plate 10 is spirally connected fixing with described D column reinforcement plate 1 simultaneously, avoids the rigidity caused due to the welding of D column reinforcement plate 1 many places and reduces.Further preferred technical scheme: the position 9 be welded and fixed described in described rear side wall internal panel and described D column reinforcement plate is positioned at the below of the position 8 that described top cover rear cross beam internal plate and described D column reinforcement plate are spirally connected fixing.Like this, avoid top cover rear cross beam internal plate 10 and be fixed on D column reinforcement plate 1, and the problem causing not prison welding to lean on.
Above-mentionedly only a kind of specific embodiment in the utility model to be illustrated; but can not as protection domain of the present utility model; every according to the change of the equivalence done by design spirit in the utility model or modification, all should think and fall into protection domain of the present utility model.
