Wherein, in order to ensure well being connected and fixed of rear row's taking-up device adapter plate 4, as shown in Fig. 2 composition graphs 1, rear row's taking-up device adapter plate 4 can comprise C post connecting portion 41 connected horizontally, rear side window connecting portion 42 and D post connecting portion 43 successively, thus the outside of above-mentioned C post connecting portion 41 can be connected and fixed with C post inner panel 2, the outside of rear side window connecting portion 42 can be connected and fixed with rear side delthyrial plate 1, the tail side of D post connecting portion 43 can be connected and fixed with D post inner panel 3.Certainly, when actual production manufactures, according to different vehicles, concrete shape and the size of above-mentioned rear row's taking-up device adapter plate 4 should carry out appropriate design, can carry out Matching installation well simultaneously fix to make rear row's taking-up device adapter plate 4 with C post inner panel 2, rear side delthyrial plate 1 and D post inner panel 3.Particularly, as shown in Figure 2, the cross-sectional plane of rear row's taking-up device adapter plate 4 can be inverted "L" shaped structure, thus the tail side of D post connecting portion 43 can be connected and fixed by the inverted "L" shaped cross-sectional plane of rear row's taking-up device adapter plate 4 and D post inner panel 3, to realize being connected with D post by C post by rear row's taking-up device adapter plate 4, improve the effect of C post and D column stiffness simultaneously.
Particularly, for the ease of rear row's taking-up device adapter plate 4 connection and improve its fixed effect, as shown in Figure 2, the outside of the C post connecting portion 41 of rear row's taking-up device adapter plate 4 upwards can be extended with the first welding edge 411, and this first welding edge 411 may be used for being welded and fixed with C post inner panel 2; The outside of rear side window connecting portion 42 upwards can be extended with the second welding edge 421, and this second welding edge 421 may be used for being welded and fixed with rear side delthyrial plate 1; One end face of the D post connecting portion 43 tail side of rear row's taking-up device adapter plate 4 can be extended with the first connection side 431 downwards, other end can be outward extended with the second connection side 432, this first connection side 431 and the second connection side 432 can be welded and fixed with D post inner panel 3 respectively in the two directions, thus the overall steadiness improving rear row's taking-up device adapter plate 4, make it have good bracing reinforcement effect, and become excellent propagation medium.Wherein, this is not restricted for the concrete form of welding, can be spot welding or seam weldering etc.
Wherein, the connection mode of the D post connecting portion 43 tail side of rear row's taking-up device adapter plate 4 can be not only welding, also can be other the mode that is connected and fixed, as shown in Figure 3, above-mentioned first connection side 431 and the second connection side 432 can be respectively equipped with multiple bolt hole 433, corresponding above-mentioned D post inner panel 3 also can be provided with mounting hole that is multiple and this bolt hole 433 Corresponding matching, thus cross first by bolt-through, second connection side (431, 432) mounting hole on the bolt hole 433 on and D post inner panel 3, with being connected and fixed between D post connecting portion 43 and D post inner panel 3 in row's taking-up device adapter plate 4 after completing.
During practical application, in order to improve the intensity of rear row's taking-up device adapter plate 4 self, as shown in Figure 3, rear row's taking-up device adapter plate 4 can be provided with reinforced rib 44.Wherein, reinforced rib 44 can be metal rod or bonding jumper; Particularly, above-mentioned reinforced rib 44 can be positioned at the bottom side that cross-sectional plane is rear row's taking-up device adapter plate 4 of inverted "L" shaped structure, and one end of reinforced rib 44 can be fixedly connected with an end face of rear row's taking-up device adapter plate 4, the other end can be fixedly connected with the other end of rear row's taking-up device adapter plate 4.
Particularly, in the vehicle side rear structure that the embodiment of the present invention provides, as shown in Figure 1, the bottom side of the C post connecting portion 41 of rear row's taking-up device adapter plate 4 can be connected with C post connecting panel 5.Wherein, shown in composition graphs 4, the outside of C post connecting panel 5 can be connected with the lower area of C post inner panel 2, the bottom side of C post connecting panel 5 can be connected with wheel cover inner panel stay bearing plate 6; The outside of wheel cover inner panel stay bearing plate 6 can be connected with rear wheel casing inner plate 7; The outside of rear wheel casing inner plate 7 can be connected with rear shock absorber adapter plate 8, the upper area of rear shock absorber adapter plate 8 can be provided with rear shock absorber attachment point 81, thus rear side delthyrial plate 1, C post inner panel 2, D post inner panel 3, rear row's taking-up device adapter plate 4, C post connecting panel 5, wheel cover inner panel stay bearing plate 6, rear wheel casing inner plate 7 and rear shock absorber adapter plate 8 entirety form vehicle side rear structure.
Wherein, installation for the ease of rear row's taking-up device adapter plate 4 is located, as shown in Figures 2 and 3, rear row's taking-up device adapter plate 4 can be provided with multiple knock hole 45, thus the accurate installation that can realize rear row's taking-up device adapter plate 4 by knock hole 45 is fixed, and then ensure the overall assembly quality of vehicle side rear structure, meet the comprehensive build guality of automobile.
Preferably, the C post connecting portion 41 of rear row's taking-up device adapter plate 4, rear side window connecting portion 42 and D post connecting portion 43 can one-body moldedly be arranged, thus the stability after improving during row's taking-up device adapter plate 4 transmissibility, avoid power, in transmittance process, disturbance occurs, and the one-body molded service life that better can ensure rear row's taking-up device adapter plate 4.
In the vehicle side rear structure provided the embodiment of the present invention below in conjunction with Fig. 1 and Fig. 4, the propagation path of vibrations and noise is described in detail.
When rear shock absorber attachment point 81 is subject to coming from the excitation of rear shock absorber in suspension, excitation (vibrations or/noise) is delivered to rear wheel casing inner plate 7 by rear shock absorber adapter plate 8, and is delivered to wheel cover inner panel stay bearing plate 6 and C post connecting panel 5 by rear wheel casing inner plate 7.Because C post connecting panel 5 is connected with C post inner panel 2 and rear row's taking-up device adapter plate 4 simultaneously, and rear row's taking-up device adapter plate 4 is connected with D post inner panel 3 again, therefore the excitation come from C post connecting panel 5 can be delivered to C post inner panel 2 successively, rear side delthyrial plate 1 and D post inner panel 3 on, namely the vibrations that are subject to of rear shock absorber attachment point 81 and noise finally can be delivered on C post and D post simultaneously, C post and D post are connected and fixed by rear row's taking-up device adapter plate 4 again simultaneously, therefore C post and D post have good rigidity, make the rigidity of rear shock absorber attachment point 81 also higher, thus make the control effects of internal car noise and vibrations better, and then improve traveling comfort and the NVH performance of automobile.
Another object of the present invention is to propose a kind of automobile, comprise vehicle side rear structure described above, with the problem of the internal car noise and shake control poor effect that solve automobile in prior art.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
