[0032] Figure 1 This is a structural diagram of a back door hinge installation structure 100 provided in an embodiment of the present application. Figure 2 This is an exploded schematic diagram of a back door hinge installation structure 100 provided in an embodiment of the present application, as shown in FIG. Figure 1 and Figure 2 As shown, the embodiment of the present application provides a tailgate hinge mounting structure 100, comprising a D-pillar upper reinforcement plate 10, a water trough 20, and a roof rear crossbeam assembly 30. The roof rear crossbeam assembly 30 comprises a roof rear crossbeam 31 and a tailgate hinge mounting plate 32. The structures and connections of the various components are described in detail below.

[0033] The D-pillar upper reinforcement plate 10 includes a first extension 11 extending along the length of the vehicle, a second extension 12 extending along the width of the vehicle, and a third extension 13 extending along the vehicle's D-pillar.

[0035] Figure 3 This is an exploded schematic diagram of a roof rear crossbeam assembly 30 provided in an embodiment of the present application, as shown in FIG. Figure 2 and Figure 3 As shown, the roof rear cross member assembly 30 includes a roof rear cross member 31 and a tailgate hinge mounting plate 32. The tailgate hinge mounting plate 32 is disposed at the end of the roof rear cross member 31. The inner edge 321 of the tailgate hinge mounting plate 32 overlaps and is welded to the end edge of the roof rear cross member 31 to form the roof rear cross member assembly 30. Compared to the existing solution in which the tailgate hinge mounting plate and the D-pillar upper reinforcement plate are integrally formed, the tailgate hinge mounting plate 32 provided in the embodiment of the present application can be formed separately, exhibiting excellent molding properties.

[0036] As an example, the number of back door hinge mounting plates 32 is two, and the two back door hinge mounting plates 32 are respectively arranged at the two ends of the roof rear cross beam 31, and the inner side edge 321 of each back door hinge mounting plate 32 is overlapped under the corresponding end edge of the roof rear cross beam 31 and is welded to the corresponding end edge of the roof rear cross beam 31.

[0037] As shown in Figure 1 and Figure 2 , the back door hinge mounting plate 32 is arranged on the second extension part 12 of the D-pillar reinforcing plate 10 and is welded to the second extension part 12, and the outer side edge 322 of the back door hinge mounting plate 32 is overlapped on the upper end edge 21 of the water channel 20 and is welded to the upper end edge 21 of the water channel 20.

[0038] As shown in Figure 3 , the back door hinge mounting plate 32 is provided with a hinge mounting groove 323 and a trim mounting groove 325. The hinge mounting groove 323 is used for mounting the back door hinge, and the hinge mounting groove 323 is provided with a first hinge mounting hole 324, which is used for connecting the back door hinge with fasteners. The trim mounting groove 325 is used for mounting the rear roof trim, and the trim mounting groove 325 is provided with a trim mounting hole 326 and a trim positioning hole 327. The trim mounting hole 326 is used for connecting the rear roof trim with fasteners, and the trim positioning hole 327 is used for positioning the rear roof trim with positioning members.

[0039] As an example, a part of the hinge mounting groove 323 is arranged in the trim mounting groove 325, which is used for mounting the end part of the back door hinge 1, and after the rear roof trim 2 is mounted in the trim mounting groove 325, the end part of the back door hinge 1 is covered by the rear roof trim 2 (see Figure 7 ); another part of the hinge mounting groove 323 extends out of the trim mounting groove 325 in the rear direction of the vehicle, which is used for the main body of the back door hinge 1 to extend rearward (see Figure 7 ) to assemble with the back door; the number of the first hinge mounting hole 324 is two, which is arranged in a part of the hinge mounting groove 323; the number of the trim mounting hole 326 is three, which is distributed around a part of the hinge mounting groove 323; the number of the trim positioning hole 327 is one, which is arranged beside one of the trim mounting holes 326 on the front side of the hinge mounting groove 323.

[0040] Further, as shown in Figure 2 , the second extension part 12 of the D-pillar reinforcing plate 10 is formed with a stepped surface 121, which matches the shape of the lower surface of the back door hinge mounting plate 32 and better matches and fits the lower surface of the back door hinge mounting plate 32.

[0041] The second extension portion 12 is also provided with a second hinge mounting hole 122 and an avoidance hole 123. The second hinge mounting hole 122 corresponds to the first hinge mounting hole 324 on the tailgate hinge mounting plate 32 and is used to cooperate with a fastener to connect the tailgate hinge 1. The avoidance hole 123 corresponds to the trim mounting hole 326 and the trim positioning hole 327 on the tailgate hinge mounting plate 32 and is used to avoid the fastener that cooperates with the trim mounting hole 326 and the positioning piece that cooperates with the trim positioning hole 327. As an example, there are two second hinge mounting holes 122 and one avoidance hole 123. The avoidance hole 123 is a waist-shaped hole and corresponds to the positions of a trim mounting hole 326 and a trim positioning hole 327 arranged adjacent to each other on the tailgate hinge mounting plate 32.

[0042] Figure 4 A schematic diagram of the welding sequence of a back door hinge installation structure 100 provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the welding sequence of the back door hinge mounting structure 100 is as follows: first, the third extension portion 13 of the D-pillar upper reinforcement plate 10 is welded to the water channel 20, and the top cover rear cross beam 31 is welded to the back door hinge mounting plate 32 to form the top cover rear cross beam assembly 30, and then Figure 4 As shown by the middle arrow, the tailgate hinge mounting plate 32 is welded to the second extension portion 12 of the D-pillar upper reinforcement plate 10 and the upper edge 21 of the water trough 20 to form the tailgate hinge mounting structure 100 .

[0043] Since the tailgate hinge mounting plate 32 is the last welding level, its dimension chain is short and the tolerance is small, and there will be no situation where errors are easily accumulated during welding due to the long dimension chain. Therefore, the tailgate hinge mounting structure 100 can improve the installation accuracy of subsequent tailgate hinges and rear roof trim panels.

[0044] Since the welding level of the back door hinge mounting plate 32 is arranged after the water flow channel 20, as shown in FIG. Figure 5 The top view of the back door hinge mounting structure 100 and Figure 6 As shown in the AA line cross-sectional diagram, the upper edge 21 of the water trough 20 is located below the outer edge 322 of the back door hinge mounting plate 32. When water flows from the back door hinge mounting plate 32 to the water trough 20, the water flows on the upper surface of the back door hinge mounting plate 32 and the water trough 20, and will not flow through the upper edge 21 of the water trough 20, thereby ensuring the sealing performance of the joint between the water trough 20 and the back door hinge mounting plate 32 and reducing the risk of water leakage.

[0045] When the back door hinge 1 and the rear roof trim 2 are installed on the back door hinge mounting plate 32, Figure 7As shown, the back door hinge 1 is a swan neck hinge, one end of the back door hinge 1 is fixed in the hinge mounting groove 323 of the back door hinge mounting plate 32 through fasteners, the main body of the back door hinge 1 extends from the hinge mounting groove 323 towards the rear direction of the vehicle for assembling the back door; the rear roof trim 2 is fixed in the trim mounting groove 325 of the back door hinge mounting plate 32 through fasteners and positioning members, and the rear roof trim 2 covers one end of the back door hinge 1. In addition, Figure 7 The side outer panel 3 connected with the first extension part 11 of the D-pillar upper reinforcement 10 and the curtain 4 connected with the rear roof trim 2 are also shown.

[0046] The embodiment of the present application also provides a vehicle comprising the back door hinge mounting structure 100.

[0047] In summary, the back door hinge mounting structure and the vehicle provided by the embodiment of the present application, the back door hinge mounting structure comprises a D-pillar upper reinforcement, a water flow groove and a roof rear cross beam assembly, the roof rear cross beam assembly comprises a roof rear cross beam and a back door hinge mounting plate, the back door hinge mounting plate can be formed separately, compared with the scheme of being formed integrally with the D-pillar upper reinforcement, the back door hinge mounting plate has good forming performance; the welding level of the back door hinge mounting plate is arranged last, has the characteristics of short size chain and small tolerance, and the situation that the error is easily accumulated in the welding process due to the long size chain does not occur, so that the installation precision of the back door hinge and the rear roof trim can be improved; the upper end edge of the water flow groove is located below the outer side edge of the back door hinge mounting plate, when the water flows from the back door hinge mounting plate to the water flow groove, the water will not flow through the upper end edge of the water flow groove, so that the sealing performance of the lap joint part of the water flow groove and the back door hinge mounting plate is ensured, and the risk of water leakage is reduced.

[0048] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of various changes or replacements within the technical range disclosed by the present application, and these should be covered within the protection scope of the present application.
