[0047] Embodiment 1
[0048] As Figure 1 shown, this embodiment provides a rear connection structure of a vehicle side wall, including: a rear wheel arch assembly 1, an upper side member 2, a D-pillar assembly 3, a connecting plate 4, and a rear wall reinforcement plate assembly 5; the connecting plate 4 is respectively connected to the upper side member 2, the D-pillar assembly 3, and the rear wall reinforcement plate assembly 5; wherein, there is a first chamber 81 between the connecting plate 4 and the upper side member 2 (see Figure 7 and Figure 10 ); the rear wall reinforcement plate assembly 5 includes an inner reinforcement plate 51 and an outer reinforcement plate 52. The top of the inner reinforcement plate 51 is connected to the connecting plate 4, the right side of the reinforcement plate is connected to the rear wheel arch assembly 1, the left side of the outer reinforcement plate 52 is connected to the left side of the inner reinforcement plate 51, the right side of the outer reinforcement plate 52 is connected to the rear wheel arch assembly 1, the upper half of the outer reinforcement plate 52 is connected to the connecting plate 4, the top of the outer reinforcement plate 52 is connected to the upper side member 2, and a second chamber 82 is formed between the outer reinforcement plate 52 and the inner reinforcement plate 51, and between the connecting plate 4 and the rear wheel arch assembly 1 (see Figure 7 and Figure 8 ), and the second chamber 82 communicates with the first chamber 81 (see Figure 7 and Figure 12 ).
[0049] In this application, the first chamber 81 communicates with the second chamber 82, so that the rear wheel arch assembly 1, the connecting plate 4, the upper side member 2, and the rear wall reinforcement plate assembly 5 form a whole, which can form an anti-torsion deformation whole when subjected to external impact, ensuring the torsional stiffness, torsional mode, and NTF performance of the rear part of the side wall; at the same time, the D-pillar assembly 3 connected to the rear wheel arch assembly 1 and the connecting plate 4 actually forms a whole with the rear wheel arch assembly 1, the connecting plate 4, the upper side member 2, and the rear wall reinforcement plate assembly 5 during actual use to form mutual support, showing integrity and coherence, thereby improving the torsional stiffness, torsional mode, and NTF performance of the vehicle body. The first chamber 81 and the second chamber 82 in this embodiment can reduce the weight of the rear connection structure of the vehicle side wall. At the same time, the connected first chamber 81 and second chamber 82 make the rear structure of the vehicle side wall form a whole, which can achieve overall anti-torsion deformation when subjected to external impact, ensuring the torsional stiffness, torsional mode, and NTF performance of the rear part of the side wall, and further ensuring the safety performance of the vehicle.
[0050] As Figure 1 and Figure 2 , and Figures 4 to 6As shown in the figure, in a specific example provided by the present application, the rear wheelhouse assembly 1 includes an outer rear wheelhouse panel 11 and an inner rear wheelhouse panel 12 respectively disposed on both sides of the connecting plate 4; the edge of the outer rear wheelhouse panel 11 has an upward connecting edge 111 that is bent and extends outward away from the outer rear wheelhouse panel 11, and the edge of the inner rear wheelhouse panel 12 has a downward connecting edge 121 that is bent and extends away from the inner rear wheelhouse panel 12. The areas where the upward connecting edge 111 and the downward connecting edge 121 are in contact with the connecting plate 4 are respectively welded to the connecting plate 4, and the upward connecting edge 111 and the downward connecting edge 121 in the remaining areas are welded together, and the upward connecting edge 111 is located above the downward connecting edge 121.
[0051] As Figure 1 , Figure 2 and Figure 10 Figure 4 shown, in a specific example provided by the present application, the rear connection structure of the vehicle side wall further includes an inner panel assembly 6; the inner panel assembly 6 includes a first inner panel 61, a second inner panel 62, a third inner panel 63, and a support plate 64. The first inner panel 61 and the second inner panel 62 are oppositely disposed on the inner rear wheelhouse panel 12, and both the first inner panel 61 and the second inner panel 62 are connected to the connecting plate 4. The bottom of the third inner panel 63 is connected to the inner rear wheelhouse panel 12, and both sides of the third inner panel 63 are respectively connected to one side of the first inner panel 61 and the second inner panel 62. The support plate 64 is connected to the tops of the first inner panel 61 and the second inner panel 62, and the adjacent two sides of the support plate 64 are respectively connected to the connecting plate 4 and the D-pillar assembly 3; the first inner panel 61, the second inner panel 62, the third inner panel 63, the support plate 64, and the inner rear wheelhouse panel 12 form a third chamber 83 (see Figure 7 and Figure 11 ). Specifically, the support member 641 includes a U-shaped sheet metal. The top of the U-shaped sheet metal is connected to the connecting plate 4, and the bottom is connected to the inner rear wheelhouse panel 12. It should still be noted that in this embodiment, the U-shaped sheet metal is in a state of lying horizontally after being rotated 90°, so that there are three support portions between the U-shaped sheet metal and the connecting plate 4, and there are also three support portions between the U-shaped sheet metal and the support plate 64.
[0052] During actual use, when the upper side member 2 is impacted by an external force, the impact force is transmitted to the U-shaped sheet metal through the connecting plate 4. The U-shaped sheet metal can support the connecting plate 4, thereby improving the anti-collision strength of the upper side member 2. At the same time, the impact force received by the upper side member 2 is transmitted to the inner panel assembly 6 and the D-pillar assembly 3 through the support plate 64, improving the bending strength of the upper side member 2.
[0053] When the upper side member 2 is impacted by an external force, the support member 641 is used to transmit and disperse the impact force received by the upper side member 2 to other parts. Since the contact area between the U-shaped sheet metal and the upper side member 2 is small, when receiving a large impact force, it will cause damage and failure of the connection between the upper side member 2 and the U-shaped sheet metal, as well as between the U-shaped sheet metal and the support plate 64, posing a safety hazard. For this reason, as Figure 1 ,Figure 2 and Figure 4 As shown in Figure 4 , in a specific example provided by the present application, an upper auxiliary plate 642 is provided on one side of the U-shaped sheet metal connected to the connecting plate 4. The upper auxiliary plate 642 is welded to the connecting plate 4, and there is an upper arc transition plate between the upper auxiliary plate 642 and the U-shaped sheet metal; a lower auxiliary plate 643 is provided on one side of the U-shaped sheet metal connected to the inner panel 12 of the rear wheel housing. The lower auxiliary plate 643 is welded to the inner panel 12 of the rear wheel housing, and there is a lower arc transition plate between the lower auxiliary plate 643 and the U-shaped sheet metal. Specifically, in this embodiment, an upper auxiliary plate 642 is provided on each of the three supporting portions where the U-shaped sheet metal contacts the connecting plate 4, and a lower auxiliary plate 643 is provided on each of the three supporting portions where the U-shaped sheet metal contacts the support plate 64.
[0054] In this embodiment, the upper auxiliary plate 642 increases the contact area between the U-shaped sheet metal and the upper side beam 2, and the lower auxiliary plate 643 increases the contact area between the U-shaped sheet metal and the support plate 64, which can ensure the stable connection between the U-shaped sheet metal and the upper side beam 2 and the support plate 64, and ensure the safety of the connection structure at the rear of the vehicle side wall.
[0055] As Figure 1 、 Figure 2 and Figure 4 As shown in Figure 1 , Figure 2 and Figure 4 , in a specific example provided by this embodiment, the connection structure at the rear of the vehicle side wall further includes a C-ring assembly mounting plate 7; the C-ring assembly mounting plate 7 for mounting the C-ring assembly 71 has a first connection portion 72 welded to the connecting plate 4, a second connection portion 73 welded to the inner reinforcement plate 51, and a third connection portion 74 connected to the inner panel 12 of the rear wheel housing. Specifically, in this embodiment, the C-ring assembly mounting plate 7 also has a fourth connection portion 75 welded to the second inner panel 62. It should be noted that in this example, the first connection portion 72, the second connection portion 73, the third connection portion 74 and the fourth connection portion 75 are connection ear structures and are welded to the corresponding components; however, the present application does not limit the specific structures of the first connection portion 72, the second connection portion 73, the third connection portion 74 and the fourth connection portion 75.
[0056] In this embodiment, during the use of the C-ring assembly 71, it is subjected to the pulling force of the seat belt, and thus the C-ring assembly mounting plate 7 is subjected to the C-ring pulling force. The C-ring assembly mounting plate 7 generates a pulling force on the connecting plate 4, the inner reinforcement plate 51, the inner panel 12 of the rear wheel housing and the second inner panel 62. The overall structure composed of the connecting plate 4, the inner reinforcement plate 51, the inner panel 12 of the rear wheel housing and the second inner panel 62 can ensure the stability of the C-pillar assembly mounting plate, ensure the stable operation of the seat belt used by the passengers in the vehicle, and thus ensure the safety of the passengers in the vehicle.
[0057] As Figure 3 、 Figure 7 、 Figure 8 and Figure 11As shown, in a specific example provided by the present application, the vehicle side rear connection structure further includes a rear pillar plate 9, which is respectively connected to the outer reinforcement plate 52, the rear wheel housing outer plate 11 and the upper side beam 2, and a third chamber 83 is provided between the rear pillar plate 9 and the connecting plate 4. Further, the outer reinforcement plate 52 includes an upper outer reinforcement plate 521 and a lower outer reinforcement plate 522; the lower outer reinforcement plate 522 is respectively connected to the rear wheel housing outer plate 11 and the rear wheel housing outer plate 11; the upper outer reinforcement plate 521 is respectively connected to the lower outer reinforcement plate 522, the rear wheel housing outer plate 11 and the rear pillar plate 9; the second chamber 82 is connected to the third chamber 83. In the present embodiment, the first chamber 81, the second chamber 82 and the third chamber 83 are in a connected state, so that when the rear pillar plate 9 is hit by an external force, the impact force can be dispersed and transmitted to the rear connecting structure of the vehicle side panel, and the rear pillar plate 9 and the rest of the connecting structure of the rear connecting structure of the vehicle side panel form an anti-torsion whole, thereby ensuring the torsional stiffness, torsional mode, and NTF performance of the rear part of the side panel, and further ensuring the safety performance of the vehicle.
[0058] like Figure 3 , Figure 7 , Figure 10 and Figure 13 As shown, in a specific example provided by the present application, a buffer plate 41 is provided on the connecting plate 4, a fourth chamber 84 is provided between the buffer plate 41 and the connecting plate 4, and the buffer plate 41 has a pressing portion 411 welded to the outer surface of the rear pillar plate 9. In this embodiment, 1, the fourth chamber 84 formed between the buffer plate 41 and the connecting plate 4 can buffer the impact of the connecting plate 4, improve the anti-twist performance of the connecting plate 4, and the pressing portion 411 can ensure the stability of the connection between the rear pillar plate 9 and the connecting plate 4, and further ensure the stability of the rear connection structure of the vehicle side enclosure.
