[0009] Furthermore, the joint body is provided with a welding through hole, and at least two of the first reinforcing rib, the second reinforcing rib, the third reinforcing rib, the fourth reinforcing rib, the fifth reinforcing rib and the sixth reinforcing rib extend to the edge of the welding through hole.

[0010] Furthermore, the edges of the welding through holes are provided with flanges.

[0011] Furthermore, a support plate is provided at the end of the third connecting part, and the third connecting part is connected to the D-column structure through the support plate.

[0043] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0044] Combination Figures 1 to 8 As shown, according to a specific embodiment of this application, a D-pillar connector is provided.

[0045] Specifically, the D-pillar connector includes: a connector body 1, which includes a first connecting part 10, a second connecting part 20, and a third connecting part 30. The first connecting part 10 is used to connect with the rear crossbeam 2 of the roof, the second connecting part 20 is used to connect with the connecting plate 3 on the C-pillar, and the third connecting part 30 is used to connect with the D-pillar structure 4. The first connecting part 10 extends in the width direction of the vehicle body and has a first boss 11 formed thereon. The first boss 11 has a hinge mounting hole 111 and protrudes outward from the vehicle body. The first connecting part 10 has a first reinforcing rib 12 and a second reinforcing rib 13. The first reinforcing rib 12 extends in the width direction of the vehicle body, and the second reinforcing rib 13 extends in the first direction to the edge of the first boss 11, and the second reinforcing rib 13 intersects with the first reinforcing rib 12.

[0046] In this embodiment, the connector body 1 is an integrally formed structure. The connector body 1 has an integrally formed first connecting portion 10, a second connecting portion 20, and a third connecting portion 30. The first connecting portion 10 has an integrally formed first boss 11, which has a hinge mounting hole 111. The first boss 11 protrudes outwards from the vehicle body to enhance the strength and rigidity of the hinge mounting point. A first reinforcing rib 12 on the first connecting portion 10 extends along the width direction of the vehicle body. The first reinforcing rib 12 not only increases the strength and rigidity of the first connecting portion 10 and the hinge mounting point, but also... Rib 12 also serves to transmit force, distributing the stress on the first connecting part 10 to other components. The second reinforcing rib 13 on the first connecting part 10 intersects with the first reinforcing rib 12, forming a mesh-like reinforcing rib structure. This further increases the strength and rigidity of the first connecting part 10 and the hinge mounting point. The second reinforcing rib 13 extends to the edge of the first boss 11, meaning that stress around the hinge mounting point can be dispersed by the second reinforcing rib 13, thus preventing cracking or deformation around the hinge mounting point due to stress concentration. The aforementioned first boss 11, first reinforcing rib 12, and second reinforcing rib 13 are integrally formed on the first connecting part 10. This integral forming process is simple, and the material thickness can be reduced through a reasonably designed reinforcing structure, solving the technical problems of complex structure and heavy weight of existing D-pillar joints.

[0047] In one exemplary embodiment of this application, such as Figure 1As shown, the connector body 1 is formed by integral die casting and has a Y-shaped structure. The connector body 1 includes a first connecting part 10, a second connecting part 20, and a third connecting part 30. The first connecting part 10 extends towards the width of the vehicle body to connect with the rear crossbeam 2 of the roof. The second connecting part 20 extends towards the front of the vehicle to connect with the connecting plate 3 on the C-pillar. The third connecting part 30 extends towards the bottom of the vehicle to connect with the D-pillar structure 4. A first boss 11 is formed on the first connecting part 10. The first boss 11 protrudes outward from the vehicle body. The side of the first boss 11 is an inclined surface. A hinge mounting hole 111 is provided on the top surface of the first boss 11. Three first reinforcing ribs 12 are provided on the first connecting part 10. The three first reinforcing ribs 12 are spaced apart along the width direction of the first connecting part 10, and each first reinforcing rib 12 extends along the width direction of the vehicle body. The first connecting part 10 is provided with four second reinforcing ribs 13. The four second reinforcing ribs 13 are spaced apart along the length direction of the first connecting part 10. The second reinforcing ribs 13 extend along the width direction of the first connecting part 10 and are perpendicular to the first reinforcing ribs 12. Both the second reinforcing ribs 13 and the first reinforcing ribs 12 have a certain height. The second reinforcing ribs 13 and the first reinforcing ribs 12 intersect to form a grid-like reinforcing rib structure. Part of the second reinforcing ribs 13 extend to the edge of the first boss 11.

[0048] like Figure 3 , Figure 4 , Figure 8 As shown, the first connecting portion 10 has an overall L-shaped structure, and has a first connecting segment extending vertically and a second connecting segment extending horizontally. The first connecting segment has two first reinforcing ribs 12, and the second connecting segment has one first reinforcing rib 12. The second connecting segment has a first boss 11, which is located near the rear edge of the first connecting portion 10.

[0049] Furthermore, the first connecting portion 10 is provided with a second protrusion 14, which protrudes outward from the vehicle body. The second protrusion 14 is connected to the first protrusion 11 along the first direction and extends to the edge of the first connecting portion 10 along the width direction of the vehicle body.

[0050] In the embodiments of this application, the second protrusion 14 extends along the width direction of the vehicle body to the edge of the first connecting portion 10. The second protrusion 14 not only serves as a positioning structure to overlap and cooperate with the protrusion on the rear crossbeam 2 of the roof, but also serves as a force transmission path to distribute the force on the first connecting structure to the rear crossbeam 2 of the roof. The second protrusion 14 is disposed with the first protrusion 11 along the first direction, which can not only increase the strength of the root of the first protrusion 11, but also distribute the force on the first protrusion 11 along the first direction to the first protrusion 11, thereby reducing the stress concentration at the root of the first protrusion 11 and improving the strength and rigidity of the first protrusion 11.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown, the first connecting portion 10 extends in the width direction of the vehicle body to connect with the rear crossbeam 2 of the roof. A second protrusion 14 on the first connecting portion 10 protrudes outwards from the vehicle body, extending along the width direction to the edge of the first connecting portion 10 to overlap with a protrusion on the rear crossbeam 2 of the roof. The second protrusion 14 is aligned with the first protrusion 11 along the width direction of the vehicle body, forming a complete force transmission channel so that the force on the first protrusion 11 is distributed to the rear crossbeam 2 of the roof via the second protrusion 14.

[0052] Furthermore, the second connecting portion 20 extends toward the front of the vehicle and is provided with a third reinforcing rib 21 and a fourth reinforcing rib 22. The third reinforcing rib 21 extends along the front of the vehicle, and the fourth reinforcing rib 22 extends along the second direction and intersects with the third reinforcing rib 21.

[0053] In the embodiments of this application, the third reinforcing rib 21 and the fourth reinforcing rib 22 intersect to form a grid-like reinforcing rib structure to enhance the rigidity and strength of the second connecting part 20. At the same time, the third reinforcing rib 21 and the fourth reinforcing rib 22 serve as force transmission structures to distribute the force on the second connecting part 20.

[0054] like Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, the second connecting portion 20 extends towards the front of the vehicle to connect with the connecting plate 3 on the C-pillar. The second connecting portion 20 has three third reinforcing ribs 21, spaced apart along the width direction of the second connecting portion 20, with each third reinforcing rib 21 extending towards the front of the vehicle. The second connecting portion 20 also has two fourth reinforcing ribs 22, spaced apart along the length direction of the second connecting portion 20. The fourth reinforcing ribs 22 are perpendicular to the third reinforcing ribs 21 to form a mesh-like reinforcing structure. Both the third reinforcing ribs 21 and the fourth reinforcing ribs 22 have a certain height.

[0055] Furthermore, the third connecting part 30 extends toward the bottom of the vehicle and is provided with a fifth reinforcing rib 31 and a sixth reinforcing rib 32. The fifth reinforcing rib 31 extends along the bottom of the vehicle and the sixth reinforcing rib 32 extends along the third direction and intersects with the fifth reinforcing rib 31.

[0056] In the embodiments of this application, the fifth reinforcing rib 31 and the sixth reinforcing rib 32 intersect to form a grid-like reinforcing rib structure to enhance the rigidity and strength of the third connecting part 30. At the same time, the fifth reinforcing rib 31 and the sixth reinforcing rib 32 serve as force transmission structures to distribute the force on the third connecting part 30.

[0057] like Figure 1 As shown, the third connecting portion 30 extends towards the bottom of the vehicle to connect with the D-pillar structure 4. The third connecting portion 30 is provided with three fifth reinforcing ribs 31, which are spaced apart along the width direction of the third connecting portion 30, and each fifth reinforcing rib 31 extends along the bottom direction of the vehicle. The third connecting portion 30 is provided with three sixth reinforcing ribs 32, which are spaced apart along the length direction of the third connecting portion 30. The sixth reinforcing ribs 32 are perpendicular to the fifth reinforcing ribs 31 to form a grid-like reinforcing structure.

[0058] Furthermore, the joint body 1 is provided with a welding through hole, and at least two of the first reinforcing rib 12, the second reinforcing rib 13, the third reinforcing rib 21, the fourth reinforcing rib 22, the fifth reinforcing rib 31 and the sixth reinforcing rib 32 extend to the edge of the welding through hole.

[0059] In the embodiments of this application, the connector body 1 is provided with a welding through hole to facilitate welding of the connector body 1 to other vehicle components; at least two of the first reinforcing rib 12, the second reinforcing rib 13, the third reinforcing rib 21, the fourth reinforcing rib 22, the fifth reinforcing rib 31, and the sixth reinforcing rib 32 extend to the edge of the welding through hole to increase the strength and rigidity of the edge of the welding through hole. Simultaneously, the stress on the edge of the welding through hole is dispersed by the reinforcing ribs to prevent deformation of the edge of the welding through hole due to stress. In addition, the welding through hole also plays a role in weight reduction.

[0060] like Figure 1 As shown, the connector body 1 is provided with a first welding through hole 40, a second welding through hole 50, and a third welding through hole 60. The first welding through hole 40 is located near the connection between the first connecting part 10 and the second connecting part 20, and a portion of the first reinforcing rib 12, a portion of the third reinforcing rib 21, and a portion of the fifth reinforcing rib 31 extend to the edge of the first welding through hole 40. The second welding through hole 50 is located at the connection between the first connecting part 10 and the third connecting part 30, and a portion of the first reinforcing rib 12, a portion of the third reinforcing rib 21, and a portion of the sixth reinforcing rib 32 extend to the edge of the second welding through hole 50; two seventh reinforcing ribs are also provided at the edge of the second welding through hole 50, one of which extends to connect with the fifth reinforcing rib 31, and the other extends to the edge of the third welding through hole 60. The third welding through hole 60 is located at the connection between the first connecting part 10 and the third connecting part 30, and a portion of the fifth reinforcing rib 31 extends to the edge of the third welding through hole 60.

[0061] Furthermore, the edge of the welding through hole is provided with a flange 70.

[0062] In the embodiments of this application, the flange 70 increases the strength and rigidity of the welded through hole edge; at the same time, the flange 70 helps to disperse the impact force and avoid stress concentration at the welded through hole edge.

[0063] like Figure 3 , Figure 5 , Figure 7 As shown, the connector body 1 is provided with a first welding through hole 40, a second welding through hole 50 and a third welding through hole 60, and the edges of the first welding through hole 40, the second welding through hole 50 and the third welding through hole 60 are all provided with flanges 70.

[0064] Furthermore, such as Figure 1 As shown, the end of the third connecting part 30 is provided with a support plate 33, and the third connecting part 30 is connected to the D-column structure 4 through the support plate 33.

[0065] In the embodiments of this application, the support plate 33 provides a more stable and rigid connection point between the third connection portion 30 and the D-column structure 4.

[0066] Furthermore, such as Figure 1 As shown, the fifth reinforcing rib 31 extends along the vehicle bottom direction to connect with the support plate 33. This arrangement helps to distribute the force on the third connection part 30 to the support plate 33 via the fifth reinforcing rib 31, and then to the D-pillar structure 4 via the support plate 33.

[0067] Furthermore, such as Figure 1 , Figure 2 As shown, the first connecting part 10 has an extension plate 15 on the side near the tailgate. The extension plate 15 extends outward toward the vehicle body and is used to connect with the lower connecting plate 5 of the rear roof crossbeam.

[0068] In the embodiments of this application, the first connecting part 10 is connected to the lower connecting plate 5 of the rear top crossbeam via the extension plate 15. The lower connecting plate 5 of the rear top crossbeam is provided with a water-stop sealing strip. This arrangement is beneficial for the installation of the water-stop sealing strip.

[0069] According to another specific embodiment of this application, a vehicle is also provided, the vehicle including the D-pillar joint in the above embodiment.
