Detailed description of the invention
The invention provides a kind of D post lower adaptor structure, for making object of the present invention, technical scheme and effect clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The application provides a kind of D post lower adaptor structure, solves the problem of D post lower adaptor structural stability difference, comprises D post and rear end beam structure.Refer to Fig. 2 a, its D post lower end schematic diagram provided for the application.As shown in Figure 2 a, described D post lower end comprises outside plate 21, D post lower reinforcing plate 22 under extended type D post, and two edges of boards of described D post lower reinforcing plate 22 are overlapped on the medial surface of outside plate 21 under described D post, form cavity body structure.
Further, see also Fig. 2 b, the cross sectional representation of its described D post provided for the application, as shown in Figure 2 b, described D post lower reinforcing plate 22 is in arch face, and under its two ends and described D post, the medial surface of outside plate 21 overlaps; Under the interior arch face of described arch face and D post, the medial surface of outside plate 21 forms cavity, guarantees the rigidity continuity of described D post, is conducive to the stability improving D post, when being connected with described rear end beam structure, and the stability of corresponding raising body tail.
Further, described lower adaptor structure also comprises rear end beam structure, for being connected with the lower end of described D post, form rigidity continuous print structure for vehicle body rear portion, refer to Fig. 3 a, its a kind of example structure schematic diagram of rear end floor beam provided for the application, described rear end beam structure comprises rear end floor beam inner panel 31, rear end floor beam outside plate 32, described rear end floor beam inner panel 31 has inner panel bottom surface 311 and inner panel side 312, described rear end floor beam 32 outside plate has outer plate top surface 321 and outside plate side 322, described inner panel bottom surface 311 overlaps with described outside plate side 322 seamed edge, described inner panel side 312 overlaps with described outer plate top surface 321 seamed edge, form the cavity body structure of both ends open.Concrete, the mode that described rear end beam structure is connected with described D post lower end is not specifically limited.
Further, consider the rigidity improving described rear end beam structure, suppress cavity generation deformation, see also Fig. 3 b, the schematic diagram of its beam structure one end, described rear end provided for the application, as shown in Figure 3 b, described rear end beam structure also comprises rear end floor beam brace panel 33, and described rear end floor beam brace panel 33 is welded on rear end floor beam two ends.Concrete, described rear end floor beam brace panel 33 welds with the inner side of described rear end floor beam inner panel 31, described rear end floor beam outside plate 32 respectively, form closed cavity, described rear end floor beam brace panel 33 is for supporting described end floor beam inner panel 31, described rear end floor beam outside plate 32, in the rear end floor beam structure be collided power time, after effective guarantee, end floor beam is stable, improves the rigidity of described rear end beam structure.
Further, if consider, described D post is connected in a welding manner with described rear end beam structure, needs to offer technique via hole, then can reduce the integrally-built body in white mode at car rear portion, screw is also offered in the two ends of described D post and rear end beam structure.During concrete enforcement, refer to Fig. 4 a, under described D post, the lower end of outside plate 21 all has screw 41; The two ends of described rear end floor beam inner panel 31 and described rear end floor beam outside plate 32 all have screw; Described D post and the connection mode of rear end beam structure are that bolt is connected.Connect compared to traditional flash butt welding, use bolt to connect can to evade the problem that car body rigidity that technique via hole brings is inadequate.
Further, refer to Fig. 4 b, it sees D post lower adaptor schematic diagram in car.As Fig. 4 b, described D post lower adaptor structure also comprises rear backplate 42, and described rear backplate 42 overlaps with described rear end floor beam inner panel 31, the stability of lifting car rear structure.Concrete, refer to Fig. 4 c, the cross-sectional of its D post lower adaptor structure provided for the application.As illustrated in fig. 4 c, described D post lower reinforcing plate 22 forms closed cavity with outside plate 21 under described D post, described rear end floor beam brace panel 33 connects described rear end floor beam inner panel 31 and described rear end floor beam outside plate 32, during described D post is connected with described rear end beam structure, described rear backplate 42 overlaps with described rear end floor beam inner panel 31, and under described D post, outside plate 21 is connected in bolt mode with described rear end floor beam outside plate 32.On the basis that the rigidity of end floor beam structure and D post improves in the rear, the rigidity of D post lower adaptor structure is improved, and then improves the mode of body in white.
