[0029] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0030] like Figures 1 to 7As shown in the figure, this embodiment provides a vehicle body structure, including: a D-pillar structure 1 and a vehicle body longitudinal beam 2. The D-pillar structure 1 includes an outer D-pillar lower joint plate 11 and an inner D-pillar lower joint plate 12. The outer D-pillar lower joint plate 11 and the inner D-pillar lower joint plate 12 are arranged opposite to each other along the wheelbase direction of the vehicle body and are connected to each other. One end of the vehicle body longitudinal beam 2 is connected to the side of the inner D-pillar lower joint plate 12 away from the outer D-pillar lower joint plate 11 along the wheelbase direction of the vehicle body, and a first connection point a is formed at the connection between the vehicle body longitudinal beam 2 and the inner D-pillar lower joint plate 12.

[0031] In this embodiment, in combination with Figure 1 As shown in the figure, the vehicle body longitudinal beam 2 is a "day" - shaped cast aluminum structure, which not only meets the requirements of lightweight of the vehicle body longitudinal beam 2, but also ensures that the vehicle body longitudinal beam 2 has sufficient strength and stiffness. Furthermore, when a vehicle collision occurs, the D-pillar structure 1 will not be squeezed and crushed to invade the occupant compartment, so as to protect the safety of the occupants.

[0032] Furthermore, the vehicle body structure further includes a first reinforcing member 3. One end of the first reinforcing member 3 is connected to the vehicle body longitudinal beam 2, and a second connection point b is formed at the connection between the first reinforcing member 3 and the vehicle body longitudinal beam 2. The other end of the first reinforcing member 3 is connected to the inner D-pillar lower joint plate 12, and a third connection point c is formed at the connection between the first reinforcing member 3 and the inner D-pillar lower joint plate 12. The first connection point a, the second connection point b, and the third connection point c respectively form the three vertices of a triangle.

[0033] In this embodiment, the D-pillar structure 1 includes an outer D-pillar lower joint plate 11 and an inner D-pillar lower joint plate 12. The vehicle body longitudinal beam 2 is connected to the side of the inner D-pillar lower joint plate 12 away from the outer D-pillar lower joint plate 11 along the wheelbase direction of the vehicle body. One end of the first reinforcing member 3 is connected to the vehicle body longitudinal beam 2, and the other end of the first reinforcing member 3 is connected to the inner D-pillar lower joint plate 12. The first connection point a formed at the connection between the vehicle body longitudinal beam 2 and the inner D-pillar lower joint plate 12, the second connection point b formed at the connection between one end of the first reinforcing member 3 and the vehicle body longitudinal beam 2, and the third connection point c formed at the connection between the other end of the first reinforcing member 3 and the inner D-pillar lower joint plate 12 respectively form the three vertices of a triangle. That is, the vehicle body longitudinal beam 2, the first reinforcing member 3, and the inner D-pillar lower joint plate 12 are connected to form a triangular structure with relatively high stability, ensuring that the D-pillar structure 1 has sufficient stiffness and strength. Furthermore, when a rear collision of the vehicle occurs, the probability that the D-pillar structure 1 is squeezed and crushed to invade the occupant compartment is reduced, so as to ensure the life safety of the occupants.

[0034] In this embodiment, the vehicle body longitudinal beam 2, the first reinforcing member 3, and the inner D-pillar lower joint plate 12 are connected by bolts, which is convenient for the installation and disassembly of the vehicle body longitudinal beam 2, the first reinforcing member 3, and the inner D-pillar lower joint plate 12, and is beneficial to improving the convenience of later maintenance.

[0035] In combination with Figure 4and Figure 5 As shown, the first reinforcing member 3 includes a first reinforcing part 31, a second reinforcing part 32 and a third reinforcing part 33. The second reinforcing part 32 is connected between the first reinforcing part 31 and the third reinforcing part 33. The first reinforcing part 31 is connected to the longitudinal beam 2 of the vehicle body, and the third reinforcing part 33 is connected to the inner plate 12 of the lower connector of the D-pillar.

[0036] In this embodiment, the first reinforcing part 31 is connected to and fits against the longitudinal beam 2 of the vehicle body; the third reinforcing part 33 is connected to and fits against the inner plate 12 of the lower connector of the D-pillar. The fit between the first reinforcing part 31 and the longitudinal beam 2 of the vehicle body, and the fit between the third reinforcing part 33 and the inner plate 12 of the lower connector of the D-pillar, helps to improve the rigidity of the connection between the first reinforcing part 31 and the longitudinal beam 2 of the vehicle body, and the rigidity of the connection between the third reinforcing part 33 and the inner plate 12 of the lower connector of the D-pillar, thus ensuring the rigidity of the connection between the first reinforcing member 3 and the longitudinal beam 2 of the vehicle body and the inner plate 12 of the lower connector of the D-pillar, thereby ensuring the reinforcing effect of the first reinforcing member 3 on the D-pillar structure 1.

[0037] Combination Figure 4 and Figure 5 As shown, the first reinforcing member 3 also includes an interior trim assembly part 34, which is located on the side of the third reinforcing member 33 away from the inner panel 12 of the lower connector of the D-pillar, and is connected to the third reinforcing member 33.

[0038] In this embodiment, the first reinforcing member 3 can serve as a load-bearing component for the vehicle interior, i.e., the interior assembly part 34 of the first reinforcing member 3 can install and support interior components; the first reinforcing member 3 can also serve as a connecting reinforcing member for the vehicle body longitudinal beam 2 and the inner panel 12 of the lower joint of the D-pillar. The first reinforcing part 31 of the first reinforcing member 3 is connected to the vehicle body longitudinal beam 2, and the third reinforcing part 33 of the first reinforcing member 3 is connected to the inner panel 12 of the lower joint of the D-pillar, which is beneficial to improving the rigidity and strength of the D-pillar structure 1, so as to realize the multi-purpose function of the first reinforcing member 3.

[0039] In this embodiment, combined with Figure 1 and Figure 2 As shown, the vehicle body structure also includes a tailgate sill outer panel 4. The tailgate sill outer panel 4 includes a first tailgate outer panel 41 and a second tailgate outer panel 42. The first tailgate outer panel 41 and the inner panel 12 of the lower connector of the D-pillar are arranged opposite to each other along the wheelbase direction of the vehicle body and are connected to each other. The first tailgate outer panel 41 is connected to the lower connector outer panel 11 of the D-pillar along the height direction of the vehicle body. The first tailgate outer panel 41 is connected to the second tailgate outer panel 42 along the track direction of the vehicle body.

[0040] It should be understood that the tailgate sill outer panel 4, which is disposed opposite to the inner panel 12 of the lower connector of the D-pillar, is part of the D-pillar structure 1, that is, the first tailgate outer panel 41 is part of the D-pillar structure 1.

[0041] In this embodiment, combined with Figure 4As shown, the vehicle body structure also includes a second reinforcing member 5, which is connected between the inner panel 12 of the lower connector of the D-pillar and the outer panel 41 of the first tailgate. This significantly increases the rigidity of the outer panel 4 of the tailgate sill, which not only improves the rigidity of the D-pillar structure 1, thereby improving the stability and smoothness of the whole vehicle, but also ensures the torsional rigidity of the tailgate, avoiding the problem of abnormal noise in the tailgate opening due to insufficient torsional rigidity of the tailgate.

[0042] In addition, the second reinforcing member 5 is connected to the first tailgate outer panel 41 by welding to ensure the firmness of the connection between the second reinforcing member 5 and the first tailgate outer panel 41.

[0043] In this embodiment, combined with Figure 3 and Figure 4 As shown, the first reinforcing member 3 and the second reinforcing member 5 are connected to the inner panel 12 of the lower joint of the D-pillar in the same area. When the triangular structure formed by the connection of the body longitudinal beam 2, the first reinforcing member 3 and the inner panel 12 of the lower joint of the D-pillar is bolted to the assembly formed by the connection of the second reinforcing member 5 and the outer panel 41 of the first tailgate, it can not only improve the stability of the triangular structure formed by the connection of the body longitudinal beam 2, the first reinforcing member 3 and the inner panel 12 of the lower joint of the D-pillar, but also improve the rigidity of the assembly formed by the inner panel 12 of the lower joint of the D-pillar, the second reinforcing member 5 and the outer panel 41 of the first tailgate, so as to further improve the rigidity of the entire D-pillar structure 1.

[0044] It should be understood that when the first reinforcing member 3 and the second reinforcing member 5 are connected to the inner panel 12 of the lower D-pillar in the same area, the orthographic projection of the first reinforcing member 3 along the wheelbase direction of the vehicle body overlaps with the orthographic projection of the second reinforcing member 5 along the wheelbase direction of the vehicle body.

[0045] Of course, in other embodiments, the first reinforcing member 3 and the second reinforcing member 5 may also be connected to the inner plate 12 of the lower connector of the D-pillar in different regions.

[0046] It should be understood that when the first reinforcing member 3 and the second reinforcing member 5 are connected to the inner panel 12 of the lower connector of the D-pillar in different areas, the orthographic projection of the first reinforcing member 3 along the wheelbase direction of the vehicle body and the orthographic projection of the second reinforcing member 5 along the wheelbase direction of the vehicle body do not overlap.

[0047] Combination Figure 4 and Figure 6 As shown, the second reinforcing member 5 includes a first reinforcing plate 51, a middle reinforcing plate 52, and a second reinforcing plate 53. The middle reinforcing plate 52 is connected between the first reinforcing plate 51 and the second reinforcing plate 53. The first reinforcing plate 51 and the second reinforcing plate 53 are arranged opposite each other along the wheel track direction of the vehicle body. The first reinforcing plate 51 and the second reinforcing plate 53 are connected between the outer panel 41 of the first tailgate and the inner panel 12 of the lower connector of the D-pillar. The middle reinforcing plate 52 is connected to the inner panel 12 of the lower connector of the D-pillar and fits together.

[0048] In this embodiment, the second reinforcing member 5 has a "U"-shaped structure, and the opening of the second reinforcing member 5 faces the outer panel 41 of the first tailgate. The first reinforcing plate 51 and the second reinforcing plate 53 can support the space between the outer panel 41 of the first tailgate and the inner panel 12 of the lower connector of the D-pillar, improve the rigidity of the D-pillar structure 1, and reduce the probability of the D-pillar structure 1 being squeezed and crushed due to collision and intruding into the passenger compartment, so as to ensure the safety of the occupants; the intermediate reinforcing plate 52 is connected to the inner panel 12 of the lower connector of the D-pillar and fits against each other, so that the second reinforcing member 5 can abut against the first reinforcing member 3, so as to further improve the rigidity of the entire D-pillar structure 1.

[0049] Furthermore, the distance between the first reinforcing plate 51 and the second reinforcing plate 53 gradually increases in the direction away from the intermediate reinforcing plate 52, making the stress on the first reinforcing plate 51 and the second reinforcing plate 53 more uniform and avoiding stress concentration that could damage the second reinforcing member 5. Both the first reinforcing plate 51 and the second reinforcing plate 53 are provided with a first connecting part 54, which connects to the outer panel 41 of the first tailgate; the intermediate reinforcing plate 52 is provided with a second connecting part 55, which connects to the outer panel 41 of the first tailgate and the inner panel 12 of the D-pillar lower connector, thus improving the connection strength of the second reinforcing member 5.

[0050] In this embodiment, combined with Figure 4 and Figure 7 As shown, the D-pillar lower joint structure also includes a third reinforcing member 6, which is connected between the inner plate 12 and the outer plate 11 of the D-pillar lower joint by welding. The connection of the third reinforcing member 6 between the inner plate 12 and the outer plate 11 of the D-pillar lower joint further enhances the rigidity and strength of the D-pillar structure 1 to meet the requirements of rigidity and strength of the D-pillar structure 1.

[0051] Combination Figure 3 , Figure 4 and Figure 7 As shown, the third reinforcing member 6 includes a third reinforcing plate 61, a fourth reinforcing plate 62, and a fifth reinforcing plate 63. The fourth reinforcing plate 62 is connected between the third reinforcing plate 61 and the fifth reinforcing plate 63. The third reinforcing plate 61 and the fifth reinforcing plate 63 are arranged opposite each other along the height direction of the vehicle body. The third reinforcing plate 61 and the fifth reinforcing plate 63 are connected between the inner plate 12 and the outer plate 11 of the lower D-pillar connector. The fourth reinforcing plate 62 is connected to the outer plate 11 of the lower D-pillar connector and fits against each other.

[0052] In this embodiment, the third reinforcement member 6 has a "ji" - shaped structure, and the opening of the third reinforcement member 6 faces the inner panel 12 of the D - pillar lower joint. The third reinforcement plate 61 and the fifth reinforcement plate 63 can support the space between the inner panel 12 of the D - pillar lower joint and the outer panel 11 of the D - pillar lower joint, improve the rigidity and strength of the D - pillar structure 1, reduce the probability that the D - pillar structure 1 is squeezed and crushed into the passenger compartment due to collision, so as to ensure the safety of the occupants; the fourth reinforcement plate 62 is connected to the outer panel 11 of the D - pillar lower joint and is in mutual contact. The fourth reinforcement plate 62 can enhance the rigidity and strength of the outer panel 11 of the D - pillar lower joint, so that when the vehicle undergoes a rear collision, the outer panel 11 of the D - pillar lower joint is not easily deformed, which is beneficial to improving the overall performance of the D - pillar structure 1.

[0053] In addition, the distance between the third reinforcement plate 61 and the fifth reinforcement plate 63 gradually increases along the direction away from the fourth reinforcement plate 62, making the forces on the third reinforcement plate 61 and the fifth reinforcement plate 63 more uniform, avoiding stress concentration and resulting in damage to the third reinforcement member 6. Both the third reinforcement plate 61 and the fifth reinforcement plate 63 are provided with a third connection portion 64, and the third connection portion 64 is connected to the inner panel 12 of the D - pillar lower joint; the fourth reinforcement plate 62 is provided with a fourth connection portion 65, and the fourth connection portion 65 is connected between the inner panel 12 of the D - pillar lower joint and the outer panel 11 of the D - pillar lower joint, which is beneficial to enhancing the connection strength of the third reinforcement member 6.

[0054] In this embodiment, the openings of the second reinforcement member 5 and the third reinforcement member 6 are arranged in different directions, making the forces on the D - pillar structure 1 more uniform, which is beneficial to enhancing the overall performance of the D - pillar structure 1.

[0055] Combined with Figure 4 As shown, a cavity 101 is formed between the inner panel 12 of the D - pillar lower joint, the outer panel 11 of the D - pillar lower joint, and the first outer panel 41 of the tailgate; among them, the second reinforcement member 5 and the third reinforcement member 6 are respectively located at both ends of the cavity 101 along the wheelbase direction of the vehicle body to cover the cavity 101.

[0056] In this embodiment, the second reinforcement member 5 and the third reinforcement member 6 cover both ends of the cavity 101, making the D - pillar structure 1 form a closed cavity 101 to enhance the torsional and bending resistance performance of the D - pillar structure 1.

[0057] In this embodiment, combined with Figure 5 、 Figure 6 and Figure 7 As shown, the first reinforcement member 3 is provided with a first weight - reducing hole 301, the second reinforcement member 5 is provided with a second weight - reducing hole 501, and the third reinforcement member 6 is provided with a third weight - reducing hole 601. The first weight - reducing hole 301, the second weight - reducing hole 501, and the third weight - reducing hole 601 can not only reduce the weight of the components to meet the requirements of lightweight; but also avoid stress concentration and resulting in damage to the components.

[0058] In addition, the directions of screwing or welding the first reinforcing member 3, the second reinforcing member 5 and the third reinforcing member 6 are all designed to take into full account the direction of force on the components, so that the stress area of ​​the D-pillar structure 1 can be smoothly transitioned and stress concentration can be avoided.
