[0044] Specifically, body joints refer to nodes in the vehicle body frame structure, such as the upper and lower ends of the B-pillar. Body joints are formed by welding together the reinforcing plates that make up the body frame, and their function is to transmit and distribute forces. Body joints involve many overlapping parts, numerous weld edges, and dense weld points, thus their structure affects the vehicle's weight and cost. The structural form of body joints also influences the vehicle's crash test, torsional stiffness, torsional mode response, and durability performance levels. Therefore, improving the structural form of body joints can effectively improve torsional stiffness and torsional mode response.

[0045] In this application embodiment, the vehicle body connector refers to... Figure 1 Points A and B shown are the upper ends of the D-pillar, specifically the upper left and upper right corners of the rear door frame, serving to connect the vehicle body in four directions: upper, lower, front, and rear. Specifically, the lower, front, and rear directions of the vehicle body, as well as the lower, front, and rear directions of the body joints, are as follows... Figure 2 As indicated by the middle arrow, the top of the vehicle body and the top of the vehicle body joint are both in the opposite direction to downward.

[0046] In the embodiments of this application, Figure 5 The front view of the vehicle body connector shown is from the left side of the vehicle body looking towards the right side. Figure 6 The left view of the vehicle body connector shown is a perspective from the front of the vehicle body to the rear. Figure 7 The top view of the vehicle body joint shown is a perspective taken from the upper part of the vehicle body to the lower part.

[0047] like Figure 2 As shown, the connection relationship between the body joint and the surrounding parts is as follows: the outer front part of the body joint connects to the C-pillar reinforcing plate 5; the inner front part of the body joint connects to the C-pillar inner panel 6; the rear part of the body joint connects to the roof rear crossbeam 7; and the lower part of the body joint connects to the lower D-pillar inner panel 8. Specifically, the outer front part of the upper D-pillar reinforcing plate 1 connects to the C-pillar reinforcing plate 5; the inner front part of the upper D-pillar inner panel 3 connects to the C-pillar inner panel 6; the rear parts of the upper D-pillar reinforcing plate 1 and the upper D-pillar inner panel 3 connect to the roof rear crossbeam 7; and the lower parts of the upper D-pillar reinforcing plate 1 and the upper D-pillar inner panel 3 connect to the lower D-pillar inner panel 8.

[0048] like Figure 3 and Figure 4 As shown, the reinforcing plate 1, the connecting plate 2, and the inner plate 3 on the D-pillar of the body joint are arranged from top to bottom. Among them, the connecting plate 2 is located at the front of the body joint.

[0049] The structure of the front part of the D-pillar upper reinforcement plate 1 and the front part of the D-pillar inner plate 3 connected by the D-pillar connecting plate 2, the structure of the rear part of the D-pillar upper reinforcement plate 1 and the rear part of the D-pillar inner plate 3, the structure of the lower part of the D-pillar upper reinforcement plate 1 and the lower part of the D-pillar inner plate 3, and the structure of the connection of the D-pillar upper reinforcement plate 1 and the D-pillar inner plate 3 and the peripheral parts, the C-pillar reinforcement plate 5, the C-pillar inner plate 6, the roof rear cross beam 7 and the D-pillar lower inner plate 8, make the vehicle body joint improve the torsional stiffness and torsional mode of the vehicle body, and have the advantages of simple process and strong implementability.

[0050] As shown in Figure 2 , Figure 6 and Figure 8 , in an embodiment, the rear lower part of the D-pillar upper reinforcement plate 1 and the rear lower part of the D-pillar inner plate 3 have two connection positions, which are the first connection position 10 and the second connection position 11, respectively. The first connection position 10 is located at the outer periphery of the rear lower part of the D-pillar upper reinforcement plate 1 and the outer periphery of the rear lower part of the D-pillar inner plate 3. The second connection position 11 is located at the bending part of the D-pillar upper reinforcement plate 1 and is located on the inner side of the first connection position 10. The D-pillar upper reinforcement plate 1, the D-pillar connecting plate 2, the D-pillar inner plate 3 and the second connection position 11 form a first cavity 12. The D-pillar upper reinforcement plate 1, the D-pillar inner plate 3, the first connection position 10 and the second connection position 11 form a second cavity 13.

[0051] As shown in Figure 8 , the rear lower part of the D-pillar upper reinforcement plate 1 and the rear lower part of the D-pillar inner plate 3 are locally connected through the second connection position 11. The rear lower part of the D-pillar upper reinforcement plate 1 and the rear lower part of the D-pillar inner plate 3 are connected through two connection positions, so that the connection structure of the D-pillar upper reinforcement plate 1 and the D-pillar inner plate 3 is stable, the torsional stiffness and torsional mode of the vehicle body are improved, and the weight of the vehicle body is reduced due to the formation of the first cavity 12 and the second cavity 13, and has better implementability.

[0052] In an embodiment, the second connection position 11 is welded to connect the D-pillar upper reinforcement plate 1 and the D-pillar inner plate 3.

[0053] Welding is a manufacturing process and technology that connects metal or other thermoplastic materials such as plastic by heating, high temperature or high pressure. It has the advantages of good connection performance, large welding structure stiffness and good integrity. The welding of the D-pillar upper reinforcement plate 1 and the D-pillar inner plate 3 makes the vehicle body joint have the advantages of simple process and strong implementability.

[0054] In an embodiment, the D-pillar upper reinforcement plate 1, the D-pillar connecting plate 2 and the D-pillar inner plate 3 are all welded.

[0055] It can be understood that, in actual applications, in order to achieve different processing requirements and functions, the connection mode of the D-pillar upper reinforcement plate 1 and the D-pillar inner plate 3 can be adjusted accordingly, and the embodiments of the present application do not limit this.

[0056] As shown in Figure 5 and Figure 11 , in an embodiment, the lower part of the D-pillar upper reinforcement plate 1 is provided with a downwardly extending flange, and the flange is connected with the D-pillar inner plate 3.

[0057] The flange refers to a structure that a certain angle straight wall or flange is formed along a closed or non-closed curved edge on the planar part or curved surface part of the blank by the action of the die. Generally, the flanging process is the last processing procedure for the profile shape or three-dimensional shape forming of the stamping part. The flange part in the embodiments of the present application is mainly used for the connection of the lower part of the D-pillar upper reinforcement plate 1 and the D-pillar inner plate 3, and the flange is connected with the D-pillar inner plate 3 to form a sealing structure.

[0058] As shown in Figure 1 and Figure 2 , in an embodiment, the upper part of the D-pillar upper reinforcement plate 1 is used for connecting with the roof sunroof reinforcement plate 9.

[0059] The upper part of the D-pillar upper reinforcement plate 1 is connected with the roof sunroof reinforcement plate 9, which can improve the torsional stiffness and torsional mode of the vehicle body.

[0060] In an embodiment, the D-pillar upper reinforcement plate 1 is welded with the roof sunroof reinforcement plate 9.

[0061] As shown in Figures 1 to 4 , in an embodiment, the vehicle body joint further comprises a hinge mounting plate 4, the hinge mounting plate 4 is located on the upper side of the rear part of the D-pillar upper reinforcement plate 1, the periphery of the hinge mounting plate 4 is connected with the D-pillar upper reinforcement plate 1, and the hinge mounting plate 4 and the D-pillar upper reinforcement plate 1 form a third cavity 14 after being connected.

[0062] The hinge mounting plate 4 is used for mounting functional parts, so that the vehicle body joint is connected with the functional parts, and the strength of the vehicle body joint can be increased, thereby improving the torsional stiffness and torsional mode of the vehicle body.

[0063] As shown in Figure 5 , Figure 7 , Figure 9 and Figure 10As shown, in one embodiment, the connection between the upper rear side of the reinforcing plate 1 on the D-pillar and the upper rear side of the inner plate 3 on the D-pillar is connected to the upper side of the hinge mounting plate 4; the connection between the rear rear side of the reinforcing plate 1 on the D-pillar and the rear rear side of the inner plate 3 on the D-pillar is connected to the rear side of the hinge mounting plate 4; and the connection between the lower rear side of the reinforcing plate 1 on the D-pillar and the lower rear side of the inner plate 3 on the D-pillar is connected to the lower side of the hinge mounting plate 4.

[0064] And such as Figure 10 As shown, the reinforcing plate 1 on the D-pillar is connected to the front side of the hinge mounting plate 4.

[0065] like Figure 7 and Figure 9 As shown, in one embodiment, a portion of the connection between the upper rear part of the reinforcing plate 1 on the D-pillar and the upper rear part of the inner plate 3 on the D-pillar is the cavity wall of the third cavity 14.

[0066] Specifically, such as Figure 9 As shown, the connection point between the right side of the reinforcing plate 1 on the D-pillar and the right side of the inner plate 3 on the D-pillar is the third connection position 15, and the right side of the hinge mounting plate 4 is connected to the third connection position 15. The left side of the reinforcing plate 1 on the D-pillar and the left side of the inner plate 3 on the D-pillar is the fourth connection position 16, and the left side of the hinge mounting plate 4 is connected to the fourth connection position 16. The fourth connection position 16 is part of the cavity wall of the third cavity 14. This structure can increase the strength of the body joint and improve the torsional stiffness and torsional mode of the body.

[0067] like Figure 9 As shown, the connection of the D-pillar reinforcing plate 1, the D-pillar inner plate 3, and the hinge mounting plate 4 forms two cavities, the first cavity 12 and the third cavity 14, at the rear of the body joint.

[0068] like Figure 5 and Figure 10 As shown, in one embodiment, a portion of the connection between the rear rear side of the reinforcing plate 1 on the D-pillar and the rear rear side of the inner plate 3 on the D-pillar is the cavity wall of the third cavity 14.

[0069] Specifically, such as Figure 10 As shown, the connection between the upper side of the reinforcing plate 1 on the D-pillar and the upper side of the inner plate 3 on the D-pillar is the fifth connection position 17. The upper side of the hinge mounting plate 4 is connected to the fifth connection position 17, and part of the fifth connection position 17 is the cavity wall of the third cavity 14. This structure can increase the strength of the body joint and improve the torsional stiffness and torsional mode of the body.

[0071] like Figures 1 to 11 As shown, the hinge mounting plate 4 is on the top layer of the body joint, located at the rear of the body joint. The layer below the hinge mounting plate 4 is the upper D-pillar reinforcing plate 1, and the bottom layer is the upper D-pillar inner plate 3. At the front of the body joint, the upper D-pillar reinforcing plate 1 and the upper D-pillar inner plate 3 are connected by the D-pillar connecting plate 2. The upper D-pillar reinforcing plate 1 and the upper D-pillar inner plate 3 run through the four directions of up, down, front, and back.

[0072] An embodiment of this application also discloses a vehicle including the body joint described in the above embodiment.

[0073] Because the body joints improve the torsional stiffness and torsional mode of the vehicle body, the vehicle's driving performance and comfort are enhanced.

[0074] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
