[0036] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0037] Reference below Figure 1-Figure 6 The side wall inner panel assembly 100 according to the embodiment of the present invention is described. The side wall inner panel assembly 100 can be applied to a vehicle.

[0038] Combination Figure 1-Figure 6 As shown, the side inner panel assembly 100 according to the utility model can mainly include: a wheel house outer panel 20, a wheel house inner panel 10 and a shock absorber support 30, the wheel house inner panel 10 is arranged on the inner side of the wheel house outer panel 20, the shock absorber support 30 is connected between the wheel house outer panel 20 and the wheel house inner panel 10, and the shock absorber support 30, the wheel house outer panel 20 and the wheel house inner panel 10 jointly define a first cavity 101.

[0039] Specifically, the wheel arch inner panel 10 and the wheel arch outer panel 20 are connected together to form a space for covering the wheel, and the shock absorber support 30 is used to set the shock absorber. The shock absorber support 30 is connected between the wheel arch outer panel 20 and the wheel arch inner panel 10, and the shock absorber support 30, the wheel arch outer panel 20 and the wheel arch inner panel 10 jointly define a first cavity 101. In this way, the shock absorber support 30 can support and strengthen the wheel arch outer panel 20 and the wheel arch inner panel 10. The first cavity 101 jointly defined by the shock absorber support 30, the wheel arch outer panel 20 and the wheel arch inner panel 10 further enhances the overall structural strength of the side inner panel assembly 100.

[0040] Furthermore, since the shock absorber support 30 is connected and fixed to the wheel arch outer panel 20 and the wheel arch inner panel 10 at the same time, the forces between the shock absorber support 30, the wheel arch outer panel 20 and the wheel arch inner panel 10 can be transmitted to each other. On the one hand, when a collision occurs at the wheel arch of the vehicle, the external force can be transmitted to the shock absorber support 30 through the wheel arch outer panel 20, and further transmitted downward to the longitudinal beam through the shock absorber support 30, thereby improving the anti-collision performance of the side panel inner panel assembly 100 and preventing the side panel inner panel assembly 100 from collapsing into the vehicle compartment during a collision. On the other hand, the upward force of the shock absorber on the shock absorber support 30 can also be transmitted to the upper part of the vehicle body through the wheel arch outer panel 20, thereby improving the structural reliability of the side panel inner panel assembly 100.

[0041] Therefore, by connecting the shock absorber support 30 between the wheel arch outer panel 20 and the wheel arch inner panel 10, the shock absorber support 30, the wheel arch outer panel 20 and the wheel arch inner panel 10 jointly define a first cavity 101, which can not only improve the structural strength of the side enclosure inner panel assembly 100, but also improve the force transmission performance and anti-collision performance of the side enclosure inner panel assembly 100, thereby improving the structural reliability of the side enclosure inner panel assembly 100.

[0042] Combination Figure 4-Figure 6 As shown, the shock absorber support 30 may include a first plate portion 31 and a second plate portion 32 connected to each other, one end of the first plate portion 31 is connected to the wheel house inner panel 10, the other end of the first plate portion 31 is spaced apart from the wheel house inner panel 10 and connected to the second plate portion 32, the second plate portion 32 is bent relative to the first plate portion 31, and one end of the second plate portion 32 away from the first plate portion 31 is connected to the wheel house outer panel 20 to define a first cavity 101.

[0043] Specifically, by connecting one end of the first plate portion 31 to the wheel house inner panel 10, the other end of the first plate portion 31 is spaced apart from the wheel house inner panel 10 and connected to the second plate portion 32, the second plate portion 32 is bent relative to the first plate portion 31, and the end of the second plate portion 32 away from the first plate portion 31 is connected to the wheel house outer panel 20, so that the structure of the shock absorber support 30 can be adapted to the structure of the wheel house inner panel 10 and the wheel house outer panel 20, which can not only facilitate the connection and fixation of the shock absorber support 30 to the wheel house inner panel 10 and the wheel house outer panel 20 respectively, but also naturally define a first cavity 101 between the shock absorber support 30, the wheel house outer panel 20 and the wheel house inner panel 10, thereby optimizing the structure of the shock absorber support 30 and even the side inner panel assembly 100, making the structure of the shock absorber support 30 and even the side inner panel assembly 100 simpler and more reliable.

[0044] Furthermore, combined with Figure 6 As shown, the first cavity 101 is an annular cavity, and the cross-section of the first cavity 101 is arc-shaped. In the length extension direction of the cross-section of the first cavity 101, the cross-sectional area of ​​the first cavity 101 is different. With such a configuration, the shape of the first cavity 101 can be optimized while ensuring that there is enough space between the wheel house inner panel 10 and the wheel house outer panel 20 to install the wheel and the shock absorber. This can not only ensure the structural stability of the first cavity 101, but also further enhance the structural strength of the side inner panel assembly 100, and optimize the force transmission performance of the first cavity 101, avoid stress concentration in the first cavity 101, and enhance the anti-collapse performance of the side inner panel assembly 100.

[0045] Combination Figure 1-Figure 6As shown, the side enclosure inner panel assembly 100 may also include: a rear side window inner panel 40 and a shock absorber support reinforcement plate 50, the rear side window inner panel 40 and the wheel house outer panel 20 are connected and fixed, the shock absorber support reinforcement plate 50 is respectively connected and fixed to the rear side window inner panel 40 and the wheel house inner panel 10, the shock absorber support reinforcement plate 50, the wheel house outer panel 20 and the wheel house inner panel 10 jointly define a second cavity 102.

[0046] Specifically, the rear side window inner panel 40 is arranged above the wheel house outer panel 20 and is connected and fixed to the wheel house outer panel 20. By arranging the shock absorber support reinforcement plate 50 on the side of the wheel house inner panel 10 away from the shock absorber support 30, the shock absorber support reinforcement plate 50 is respectively connected and fixed to the rear side window inner panel 40 and the wheel house inner panel 10, and the shock absorber support reinforcement plate 50, the wheel house outer panel 20 and the wheel house inner panel 10 jointly define a second cavity 102, so that the shock absorber support reinforcement plate 50 can support and strengthen the rear side window inner panel 40 and the wheel house outer panel 20, and the second cavity 102 jointly defined by the shock absorber support reinforcement plate 50, the wheel house outer panel 20 and the wheel house inner panel 10 can further enhance the overall structural strength of the side inner panel assembly 100.

[0047] Furthermore, since the shock absorber support reinforcement plate 50 is respectively connected and fixed to the rear side window inner panel 40 and the wheel arch inner panel 10, and the wheel arch inner panel 10 is connected and fixed to the shock absorber support 30, on the one hand, when a collision occurs at the wheel arch of the vehicle, the external force can be transmitted to the shock absorber support 30 through the wheel arch outer panel 20. In addition to being transmitted downward to the longitudinal beam through the shock absorber support 30, the force can also be transmitted to the shock absorber support reinforcement plate 50 and then to the rear floor crossbeam. In this way, the external force can be dispersed to different parts, thereby preventing the side panel inner panel assembly 100 from collapsing into the vehicle compartment and reducing damage to users in the vehicle compartment. On the other hand, the shock absorber force exerted on the shock absorber support 30 can also be transmitted upward through the rear side window inner panel 40, thereby further improving the force transmission performance of the side panel inner panel assembly 100 and improving the structural reliability of the side panel inner panel assembly 100.

[0048] Furthermore, combined with Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the shock absorber support reinforcement plate 50 may include: a third plate portion 51 and a fourth plate portion 52 that are interconnected, one end of the third plate portion 51 is connected to the wheel house inner panel 10, the other end of the third plate portion 51 is spaced apart from the wheel house inner panel 10 and connected to the fourth plate portion 52, the fourth plate portion 52 is bent relative to the third plate portion 51, and one end of the fourth plate portion 52 away from the third plate portion 51 is connected to the rear side window inner panel 40 to define a second cavity 102.

[0049] Specifically, by connecting one end of the third plate portion 51 to the wheel house inner panel 10, the other end of the third plate portion 51 is spaced from the wheel house inner panel 10 and connected to the fourth plate portion 52, the fourth plate portion 52 is bent relative to the third plate portion 51, and the end of the fourth plate portion 52 away from the third plate portion 51 is connected to the rear side window inner panel 40, so that the structure of the shock absorber support reinforcement plate 50 can be adapted to the structures of the rear side window inner panel 40 and the wheel house inner panel 10, which can not only facilitate the connection and fixation of the shock absorber support reinforcement plate 50 to the rear side window inner panel 40 and the wheel house inner panel 10 respectively, but also naturally define a first cavity 101 between the shock absorber support reinforcement plate 50, the wheel house outer panel 20 and the wheel house inner panel 10, thereby optimizing the structure of the shock absorber support reinforcement plate 50 and even the side panel inner panel assembly 100, making the structure of the shock absorber support reinforcement plate 50 and even the side panel inner panel assembly 100 simpler and more reliable.

[0050] Combination Figure 6 As shown, the second cavity 102 is an annular cavity, and the second cavity 102 is arranged on the upper side of the first cavity 101. The second cavity 102 may include a first sub-cavity 1021 and a second sub-cavity 1022. The cross-section of the first sub-cavity 1021 is arc-shaped and the cross-sectional area gradually increases in the extension direction from bottom to top. The first sub-cavity 1021 and at least part of the first cavity 101 are in contact with each other and support each other with the first cavity 101. The second sub-cavity 1022 is connected to the upper end of the first sub-cavity 1021 and extends upward.

[0051] In this way, on the one hand, the shape of the second cavity 102 can be optimized, which not only ensures the structural stability of the second cavity 102, but also strengthens the connection between the rear side window inner panel 40 and the wheel arch inner panel 10, further improves the structural strength of the side panel inner panel assembly 100, and optimizes the force transmission performance of the second cavity 102, avoids stress concentration in the second cavity 102, and enhances the anti-collapse performance of the side panel inner panel assembly 100. On the other hand, the second cavity 102 and the first cavity 101 can be at least partially supported by each other in the up and down directions, thereby further improving the structural strength of the side panel inner panel assembly 100, and improving the force transmission performance and anti-collapse performance of the side panel inner panel assembly 100.

[0052] In addition, unlike the prior art that uses multiple shock absorber support reinforcement plates to ensure the structural strength of the side inner panel assembly, the shock absorber support reinforcement plate 50 of the present application only requires one shock absorber support reinforcement plate 50 while improving the structural strength of the side inner panel assembly 100, thereby reducing the number of components, which can not only improve welding accuracy, but also reduce the number and weight of molds, reduce mold development costs and stamping costs, and shorten mold development time.

[0053] Combination Figure 1-Figure 6As shown, the side enclosure inner panel assembly 100 may also include: a C-pillar reinforcement plate 60, the C-pillar reinforcement plate 60 is located in front of the rear side window inner panel 40 and is connected and fixed to the rear side window inner panel 40, the C-pillar reinforcement plate 60 is connected and fixed to the wheel house outer panel 20, and the C-pillar reinforcement plate 60 and the wheel house outer panel 20 jointly define a third cavity 103.

[0054] Specifically, by connecting and fixing the C-pillar reinforcement plate 60 to the rear side window inner panel 40 and the wheel house outer panel 20 respectively, the C-pillar reinforcement plate 60 and the wheel house outer panel 20 jointly define a third cavity 103, so that the C-pillar reinforcement plate 60 can support and strengthen the wheel house outer panel 20 and the rear side window inner panel 40, and the third cavity 103 jointly defined by the C-pillar reinforcement plate 60 and the wheel house outer panel 20 can further enhance the overall structural strength of the side inner panel assembly 100.

[0055] Furthermore, since the C-pillar reinforcement plate 60 is respectively connected and fixed to the rear side window inner panel 40 and the wheel house outer panel 20, force can be transmitted between the C-pillar reinforcement plate 60, the wheel house outer panel 20 and the rear side window inner panel 40, and the wheel house outer panel 20 is connected and fixed to the shock absorber support 30, the upward force of the shock absorber on the shock absorber support 30 can be transmitted to the upper body through the C-pillar reinforcement plate 60, thereby improving the force transmission performance of the side panel inner panel assembly 100 and improving the structural reliability of the side panel inner panel assembly 100.

[0056] Furthermore, combined with Figure 6 As shown, the third cavity 103 is an annular cavity, which is arranged on the upper side of the first cavity 101 and supported between the second sub-cavity 1022 and the first cavity 101, and the cross-sectional area of ​​the third cavity 103 gradually decreases in the direction from bottom to top. With such an arrangement, on the one hand, the shape of the third cavity 103 can be optimized, which can not only ensure the structural stability of the third cavity 103, but also strengthen the connection between the rear side window inner panel 40 and the wheel arch outer panel 20, and further improve the structural strength of the side enclosure inner panel assembly 100, but also optimize the force transmission performance of the third cavity 103, avoid stress concentration in the third cavity 103, and enhance the anti-collapse performance of the side enclosure inner panel assembly 100. On the other hand, the third cavity 103 and the first cavity 101 can at least partially support each other in the up and down directions, so as to further improve the structural strength of the side enclosure inner panel assembly 100, and improve the force transmission performance and anti-collapse performance of the side enclosure inner panel assembly 100.

[0057] In the above, the side inner panel assembly 100 is formed with at least a first cavity 101, a second cavity 102 and a third cavity 103, and the second cavity 102 and the third cavity 103 are arranged in the inward and outward directions, and the first cavity 101 is located below the second cavity 102 and the third cavity 103. In this way, the first cavity 101, the second cavity 102 and the third cavity 103 can support and reinforce each other, thereby effectively improving the structural strength of the side inner panel assembly 100, and effectively improving the NVH performance and durability performance of the side inner panel assembly 100.

[0058] Furthermore, the shock absorber support 30 is respectively connected and fixed to the C-pillar reinforcement plate 60 and the shock absorber support reinforcement plate 50. Specifically, by connecting and fixing the shock absorber support 30 to the C-pillar reinforcement plate 60 and the shock absorber support reinforcement plate 50, on the one hand, the upward force of the shock absorber received by the shock absorber support 30 can also be directly transmitted to the C-pillar reinforcement plate 60 and the shock absorber support reinforcement plate 50, that is, the shock absorber support 30 can directly transmit force through the C-pillar reinforcement plate 60 and the shock absorber support reinforcement plate 50, thereby further improving the force transmission effect of the side inner panel assembly 100 to the upper part of the vehicle body and improving the structural reliability of the side inner panel assembly 100.

[0060] In addition, the side inner panel assembly 100 also includes: a shock absorber support plate 80, the shock absorber support 30 is provided with an avoidance hole 33, the shock absorber support plate 80 is arranged in the avoidance hole 33, and is connected and fixed to the wheel arch inner panel 10, thereby further improving the structural strength of the side inner panel assembly 100.
