[0029] The assembly of multiple parts such as the D-pillar upper connector, electric strut mounting plate and hinge reinforcement plate is difficult to control in terms of assembly accuracy. On the other hand, it increases the weight of the vehicle body and the connection strength between multiple parts is insufficient. Therefore, it is necessary to improve the rear structure of the vehicle body, improve assembly accuracy, reduce the weight of the vehicle body and increase the strength of the vehicle body.
[0030] In order to solve the problems in the related art, the present application provides a D-pillar connector, see Figure 1 , Figure 1 This is a first-perspective structural diagram of the D-pillar connector provided in this application.
[0031] The D-pillar connector 1 of the present application includes an integrally arranged D-pillar connector body 10 and an electric strut mounting structure 20. The D-pillar connector body 10 has a first connector portion 110, a second connector portion 120 and a third connector portion 130 that are interconnected. The first connector portion 110, the second connector portion 120 and the third connector portion 130 are bent and connected to each other. The first connector portion 110 is used to connect to the vehicle's D-pillar, the second connector portion 120 is used to connect to the vehicle's C-pillar, and the third connector portion 130 is used to connect to the vehicle's cross beam. The electric strut mounting structure 20 is located at the first connector portion 110.
[0032] The first joint portion 110, second joint portion 120, and third joint portion 130 of the integrated D-pillar connector 1 connect the vehicle's D-pillar, vehicle's C-pillar, and vehicle's cross beam into a single unit, providing more uniform stress distribution and strengthening the connection strength between the vehicle's D-pillar, vehicle's C-pillar, and vehicle's cross beam. The integrated electric strut mounting structure 20 on the D-pillar connector 1 provides a mounting location for the electric strut, eliminating the need for additional components to install the electric strut, reducing the use of components and allowing the electric strut mounting structure 20 to be integrally connected to the D-pillar connector 1. This avoids assembly precision issues between the D-pillar connector 1 and the electric strut mounting structure 20, as well as the need to separately weld the electric strut mounting structure 20, which would pose a greater risk of cracking and falling off due to excessive local stress. This improves assembly precision and the connection strength of the electric strut, thereby increasing the strength of the entire vehicle and reducing its weight. It should be noted that the D-pillar joint 1 is cast from aluminum alloy material, so various structures can be formed on the D-pillar joint 1, making it convenient to integrate the electric strut mounting structure 20 thereon, avoiding the risk of falling off during additional welding of the electric strut mounting structure 20, resulting in insufficient connection strength of the electric strut. The D-pillar joint 1 is connected to the vehicle's D-pillar, vehicle's C-pillar and vehicle's cross beam using the SPR process, which helps to further improve the connection strength. The overall material thickness of the D-pillar joint 1 is 2.5 to 3 mm.
[0033] The D-pillar joint 1 includes a hinge mounting structure 30, which is integrally formed with the D-pillar joint body 10 and located on the third joint portion 130. The hinge mounting structure 30 is used to mount the tailgate hinge, which connects the tailgate. Therefore, stress on the tailgate is transmitted to the hinge mounting structure 30 through the tailgate hinge. The integration of the hinge mounting structure 30 into the D-pillar joint 1 eliminates the need for separate welding of the hinge mounting structure 30, avoids assembly precision issues between the D-pillar joint 1 and the hinge mounting structure 30, and reduces vehicle weight. Furthermore, stress on the hinge mounting structure 30 is shared by the D-pillar joint 1 and then transmitted to the vehicle's D-pillar, C-pillar, and cross member. This ensures more uniform stress distribution and avoids the risk of cracking and separation of the hinge mounting structure 30 due to excessive localized stress that can occur when the hinge mounting structure 30 is welded separately.
[0034] The D-pillar joint 1 includes a rubber coating structure 40, which is integrally formed with the D-pillar joint body 10. The rubber coating structure 40 is located in the third joint portion 130 and is connected to the hinge mounting structure 30. The rubber coating structure 40 is used to strengthen the connection to the vehicle roof. The integration of the rubber coating structure 40 on the D-pillar joint 1 avoids assembly precision issues between the D-pillar joint 1 and the rubber coating structure 40, improving assembly accuracy. The D-pillar joint 1 and the rubber coating structure 40 share the load, preventing the risk of the rubber coating structure 40 falling off due to excessive local stress when welding the rubber coating structure 40 separately, thereby improving the overall connection strength. The rubber coating structure 40 and the hinge mounting structure 30 are integrally connected in an L-shape, creating a good force transmission path between the vehicle roof and tailgate, which helps to improve vehicle strength.
[0035] The glue coating structure 40 is formed with a glue coating groove 410, which is located at the third joint portion 130. The third joint portion 130 is connected to the vehicle cross beam. The glue coating groove 410 is used to apply glue to assist in strengthening the connection between the vehicle roof and the vehicle cross beam.
[0036] See also Figure 2 , Figure 2 This is a schematic structural diagram of the D-pillar connector 1 provided in this application from a second perspective.
[0037] The glue coating structure 40 has a glue coating cavity 420, the opening of which faces away from the glue coating groove 410. A glue coating reinforcement rib 430 is disposed within the glue coating cavity 420. The glue coating structure 40 is a raised cavity structure. The glue coating cavity 420 allows the glue coating structure 40 to bend and extend in different directions, which helps to improve the torsional stiffness of the glue coating structure 40 and the D-pillar joint 1. The glue coating groove 410 is located on one side of the D-pillar joint 1, and the glue coating cavity 420 opens on the other side of the D-pillar joint 1. The glue coating reinforcement rib 430 further enhances stiffness.
[0038] The electric support pole mounting structure 20 comprises a base boss 210 and a fixing boss 220. The base boss 210 is connected to the first joint portion 110, and the fixing boss 220 is connected to the base boss 210. The fixing boss 220 is provided with a mounting hole. The base boss 210 protrudes from one side of the D-pillar joint 1, allowing the electric support pole mounting structure 20 to bend and extend in different directions, which helps to improve the torsional stiffness of the electric support pole mounting structure 20 and the D-pillar joint 1. The base boss 210 is also provided with multiple fixing bosses 220. The fixing bosses 220 protrude from the base boss 210 and are arranged at intervals. The number of fixing bosses 220 can be two, three, or other numbers, depending on the actual situation. The mounting holes in the fixing bosses 220 are used for threaded connection with the electric support pole.
[0039] The D-pillar joint 1 is also provided with crisscross fence reinforcement ribs 50 , which extend on the first joint portion 110 , the second joint portion 120 and the third joint portion 130 , and are simultaneously connected to the circumference of the base boss 210 and the fixing boss 220 .
[0040] The fence reinforcement rib 50 is in a convex shape, which further strengthens the strength of the D-pillar joint 1, and at the same time enables better force transmission between the first joint part 110, the second joint part 120 and the third joint part 130. The fence reinforcement rib 50 simultaneously connects the base boss 210 and the surrounding sides of the fixed boss 220 and between adjacent fixed bosses 220, which helps to improve the strength of the electric support pole mounting structure 20.
[0041] The base boss 210 forms a base cavity 2110, the opening of the base cavity 2110 is away from the fixed boss 220, and a base reinforcement rib 2120 is provided in the base cavity 2110. The base boss 210 protrudes from one side of the D-pillar joint 1, and the opening of the base cavity 2110 faces the other side of the D-pillar joint 1. The base reinforcement ribs 2120 are arranged in a crisscross manner. The arrangement of the base reinforcement ribs 2120 helps to further strengthen the strength of the base boss 210, thereby further improving the strength of the electric support pole mounting structure 20 and the D-pillar joint 1.
[0042] To sum up, the D-pillar joint 1 of the present application integrates the electric strut mounting structure 20 in the first joint part 110, and integrates the hinge mounting structure 30 and the glue coating structure 40 in the third joint part 130, which reduces the use of parts, avoids the assembly accuracy problems of the D-pillar joint 1 and multiple parts, improves the assembly accuracy, reduces the weight, reduces the risk of cracking and falling off of the electric strut mounting structure 20, the hinge mounting structure 30 and the glue coating structure 40, strengthens the connection strength between the D-pillar joint 1 and the electric strut mounting structure 20, the hinge mounting structure 30 and the glue coating structure 40, and optimizes the stress condition.

The D-pillar connector 1 is connected to the D-pillar, the vehicle C-pillar, and the vehicle cross beam. The D-pillar connector assembly of the present application has high assembly precision, light weight, and high strength. It should be noted that the edge where the first connector portion 110 and the third connector portion 130 of the D-pillar connector 1 are connected is also bent and connected to a D-pillar connecting plate 2. The D-pillar connecting plate 2 also connects the vehicle cross beam and the D-pillar. The D-pillar connector 1 does not cover the surface of the D-pillar connecting plate 2. The surface of the D-pillar connecting plate 2 is used for the installation of a sealing strip. The size of the D-pillar connector 1 is designed to leave space to avoid affecting the installation of the sealing strip.
