[0032] The following provides a detailed description of the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.

[0033] In the present disclosure, unless otherwise stated, the directional words used, such as "upper, lower, top, and bottom", generally refer to the upper, lower, top, and bottom of the corresponding component in the direction of gravity when in use, and "inside and outside" refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first, second, and third", etc., are used to distinguish one element from another, and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0034] In related technologies, such as Figure 2 As shown, the side edge of the D-pillar is connected to the body floor through a connecting plate, and the cavity structure of the D-pillar is interrupted, resulting in a relatively weak connection between the D-pillar and the body floor and insufficient strength.

[0035] The present disclosure provides a D-pillar connection device, comprising: a connection seat 2, the connection seat 2 is used to be arranged on the upper surface of the vehicle body bottom plate 4, and one end of the connection seat 2 facing away from the vehicle body bottom plate 4 is connected to the end of the D-pillar 1, so that the installation point of the D-pillar 1 is located on the upper surface of the vehicle body bottom plate 4.

[0036] Through the above technical solution, in the D-pillar connection device provided by the present disclosure, the D-pillar 1 is installed on the upper surface of the vehicle body bottom plate 4 through the connection seat 2, so that the end surface of the D-pillar 1 is completely connected to the vehicle body bottom plate 4, the connection area between the D-pillar 1 and the vehicle body bottom plate 4 is increased, and at the same time, the D-pillar 1 and the vehicle body bottom plate 4 form a continuous cavity, such as Figure 3 As shown, the rigidity of the D-pillar 1 and the connection strength with the vehicle body bottom panel 4 are enhanced.

[0037] As an optional implementation, Figure 1 As shown, the end of the connecting seat 2 away from the vehicle body bottom plate 4 has a mounting opening that matches the outer diameter of the D-pillar 1. The D-pillar 1 is inserted into the mounting opening and connected to the side wall of the mounting opening, rather than directly connecting the end surface of the D-pillar 1 with the end surface of the connecting seat 2. The mounting opening can limit and fix the D-pillar 1, thereby ensuring the connection strength between the D-pillar 1 and the connecting seat 2.

[0038] As an optional implementation, Figure 6 As shown, the connecting seat 2 is constructed as a first cavity, and the D-pillar 1 is connected to the vehicle body bottom plate 4 through the connecting seat 2, so that the cavity of the D-pillar 1 remains continuous. The connecting seat 2 is constructed as a cavity to reduce the weight of the vehicle body and increase the strength compared to the connecting plate.

[0039] Alternatively, if Figures 4 - 6As shown, the connecting seat 2 includes a first connecting plate 21 and a second connecting plate 25. The first connecting plate 21 and the second connecting plate 25 are connected and both are configured as L-shaped to enclose a first cavity. The connecting seat 2 is a rectangular cavity formed by two L-shaped connecting plates. By setting the connecting seat 2 in a split manner, on the one hand, it is convenient for processing and installation in terms of technology, convenient for welding points, and at the same time convenient for connecting and installing the components inside the first cavity. For example, during installation, the first connecting plate 21 can be welded to the vehicle body floor 4 first, and the second connecting plate 25 can be welded to the bottom of the D-pillar 1. Then, the D-pillar 1 is placed at the installation point position, the D-pillar 1 is welded to the first connecting plate 21, and the second connecting plate 25 is welded to the first connecting plate 21 and the vehicle body floor 4. This welding method can make the welding points of the first connecting plate 21 and the second connecting plate 25 with the D-pillar 1 not on the same cross-section. For example, the welding position of the second connecting plate 25 is higher than the welding position of the first connecting plate 21 and the D-pillar 1, so as to disperse the stress and increase the stability of the D-pillar 1. It can also make the height of the second connecting plate 25 greater than the height of the first connecting plate 21 to increase the connection area between the second connecting plate 25 and the D-pillar 1, and prevent the D-pillar 1 from being inserted too deep into the first cavity and affecting the installation of the components inside the first cavity. Of course, in other embodiments, the connecting seat 2 can also be integrally provided, or can be surrounded by three or four connecting plates.

[0040] Optionally, as Figures 5 - 6 and Figure 8 shown, a rear bulkhead assembly 3 is provided on the vehicle body floor 4. The rear bulkhead assembly 3 is used to connect the rear bulkhead of the vehicle body. The rear bulkhead assembly 3 is configured as a second cavity extending along the edge of the vehicle body floor 4. The first cavity is communicated with the second cavity. The D-pillar 1 not only forms a continuous cavity with the vehicle body floor 4, but also forms a continuous cavity with the rear bulkhead assembly 3, increasing the connection strength on the side of the D-pillar 1.

[0041] Optionally, as Figure 5 、 Figure 8 and Figure 10 shown, the first cavity includes a connecting section 23 and a transition section 24. The connecting section 23 is used to connect with the D-pillar 1, and the transition section 24 extends towards the rear bulkhead assembly 3 and is used to connect with the rear bulkhead assembly 3. The connecting device further includes an inner support plate 8. One end of the inner support plate 8 is located inside the transition section 24 and is connected to the transition section 24, and the other end is located inside the second cavity and is connected to the second cavity. The first cavity is communicated with the second cavity through the transition section 24. An inner support plate 8 is connected between the transition section 24 and the second cavity to increase the connection strength. For example, the inner support plate 8 includes a connecting edge connected to at least two side walls of the second cavity and a second flanging 82 used to connect with the first cavity and the second cavity. A welding through hole 81 is provided on the side of the inner support plate 8 facing the first cavity for welding the connecting plate and the second flanging 82 to the second cavity. This is also the advantage of setting the connecting seat 2 in a split manner.

[0042] Optionally, asFigure 5 , Figure 9 and Figure 11 As shown, the connection seat 2 also includes a third connection plate 22, a transition section 24 is formed on the first connection plate 21 to connect with the rear panel assembly 3, one side plate of the first connection plate 21 is connected to the side of the rear panel assembly 3 away from the vehicle body bottom plate 4, and the other side plate is connected to the side of the rear panel assembly 3 close to the inner side of the vehicle body bottom plate 4, the third connection plate 22 and the transition section 24 extend in the same direction and are connected to the first connection plate 21 and the rear panel assembly 3, and the third connection plate 22 is connected to the vehicle body bottom plate 4, the third connection plate 22 connects the first connection plate 21, the rear panel assembly 3 and the vehicle body bottom plate 4, and enhances the strength of the connection between the three. At the same time, because the first connection plate 21 is both L-shaped and needs to form a transition section 24, the processing difficulty is relatively large. By setting the third connection plate 22 to connect the first connection plate 21 with the vehicle body bottom plate 4, the processing difficulty of the first connection plate 21 is also reduced. In other embodiments, the first connection plate 21 can also be directly connected to the vehicle body bottom plate 4.

[0043] As an optional implementation, Figure 7 As shown, the connecting device also includes a hinge reinforcement plate 7 for installing the tailgate hinge 6. The hinge reinforcement plate 7 is arranged in the first cavity. The first cavity is provided with a mounting hole so that the tailgate hinge 6 can be installed and extend into the first cavity through the mounting hole to be connected with the hinge reinforcement plate 7. The tailgate disclosed in the present invention is a side-opening tailgate, so the tailgate hinge 6 is located on the side of the vehicle body. The higher the rigidity of the installation point of the tailgate hinge 6, the more conducive it is to resist the sinking deformation of the vehicle door, so a hinge reinforcement plate 7 is provided. The hinge reinforcement plate 7 is arranged in the first cavity to reduce the occupied space, while enhancing the strength of the connecting seat 2, thereby enhancing the stability of the D-pillar 1.

[0044] Among them, the hinge reinforcement plate 7 includes a mounting plate 71 and a reinforcement plate 72. The mounting plate 71 is constructed in an L shape. The reinforcement plate 72 is arranged on the inner side of the mounting plate 71 and connected to the two side plates of the mounting plate 71. The two side plates of the mounting plate 71 and the reinforcement plate 72 are both provided with a first flange 73. The two side plates of the mounting plate 71 are connected to one of the first connecting plate 21 or the second connecting plate 25, and are connected to the other of the two through the first flange 73. For example, the mounting plate 71 is connected to the second connecting plate 25, and the first flange 73 is connected to the first connecting plate 21. The mounting plate 71 is L-shaped and welded to the two side plates of the second connecting plate 25. The reinforcement plate 72 is vertically arranged to the mounting plate 71 to increase the strength of the hinge reinforcement plate 7. The hinge reinforcement plate 7 strengthens the connection strength with the first connecting plate 21 by setting the first flange 73. The hinge reinforcement plate 7 is connected to both the first connecting plate 21 and the second connecting plate 25, thereby increasing the connection strength between the first connecting plate 21 and the second connecting plate 25.

[0045] like Figure 1 andFigures 4 - 5 As shown in the figure, the second object of the present disclosure is to provide a vehicle body structure, including: a vehicle body floor 4; a D-pillar 1; and the connecting device of the above-mentioned D-pillar. The D-pillar 1 is connected to the vehicle body floor 4 through the connecting device. The D-pillar 1 is installed on the upper surface of the vehicle body floor 4 through a connecting seat 2, so that the end face of the D-pillar 1 is completely connected to the vehicle body floor 4, increasing the connection area between the D-pillar 1 and the vehicle body floor 4. At the same time, a continuous cavity is formed between the D-pillar 1 and the vehicle body floor 4 to enhance the stiffness of the D-pillar 1 and the connection strength with the vehicle body floor 4.

[0046] Optionally, as Figure 4 shown, the vehicle body structure further includes an inner wheelhouse panel 5 provided on the vehicle body floor 4. The D-pillar 1 overlaps and is connected to one side of the inner wheelhouse panel 5. The inner wheelhouse panel 5 is also configured as a cavity structure. The side surfaces of the D-pillar 1 and the inner wheelhouse panel 5 overlap and are connected, increasing the connection area between the two. At the same time, a continuous strength is formed between the D-pillar 1 and the inner wheelhouse panel 5, increasing the stability of the D-pillar 1.

[0047] The third object of the present disclosure is to provide a vehicle, including: the above-mentioned vehicle body structure. The vehicle body structure of the present disclosure can increase the connection strength between the D-pillar 1, the vehicle body floor 4, and the inner wheelhouse panel 5, thereby increasing the strength and stiffness of the vehicle body and making the vehicle safer.

[0048] The components in the present disclosure are connected by welding. Spot welding can be directly used for welding at unobstructed places, and plug welding holes can be provided for plug welding at obstructed places. When performing plug welding, two or several workpieces are overlapped, and one or several of them are provided with plug welding holes, and then welds are formed in the plug welding holes to fill the plug welding holes.
