[0032] The present application provides a trunk lid assembly and a vehicle.

[0033] The trunk lid assembly of the embodiment of the present application is described below.

[0034] See also Figure 1-Figure 3 , Figure 1 A three-dimensional diagram of a trunk lid assembly provided in some embodiments of the present application, Figure 2 A cross-sectional view of a trunk lid assembly provided in some embodiments of the present application, Figure 3 Schematic diagram of a reinforcement plate provided in some embodiments of the present application. The present application provides a trunk lid assembly 100. The trunk lid assembly 100 includes an outer panel 1, an inner panel 2 and a reinforcement plate 3.

[0035] The inner panel 2 may be disposed on one side of the outer panel 1 .

[0036] The reinforcing plate 3 may include a body 31, a first flange 32 and a second flange 33. The body 31 is connected to the inner plate 2. For example, the body 31 may be connected to the inner plate 2 by welding.

[0037] The body 31 has a groove 314 and a hinge connection part 313. The reinforcing plate 3 can be connected to the hinge seat through the hinge connection part 313. Exemplarily, the hinge connection part 313 can be located at the bottom of the groove 314, and the hinge connection part 313 can be a hole formed on the body 31. A nut can be provided to be welded to the reinforcing plate 3, and then the hinge connection part 313 is penetrated by a bolt to connect the body 31 and the hinge seat.

[0038] The groove 314 may have an opening 351, and the opening 351 is opposite to the outer panel 1. Specifically, the surface of the body 31 on one side close to the outer panel 1 may be recessed away from the outer panel 1 to form the groove 314, and the orthographic projection of the opening 351 of the groove 314 on the plane where the outer panel 1 is located is located inside the outer panel 1.

[0039] The groove 314 and the outer plate 1 form a cavity 35. Specifically, the outer plate 1 is covered with the groove 314, so that the outer plate 1 and the groove 314 can enclose the cavity 35 together.

[0040] The first flange 32 and the second flange 33 may be arranged at intervals on the outer periphery of the opening 351 and extend in a direction away from the body 31, and both the first flange 32 and the second flange 33 are connected to the outer panel 1. Specifically, the first flange 32 and the second flange 33 are arranged at intervals, and the first flange 32 and the second flange 33 are folded from the edge of the opening 351 in a direction away from the side wall of the body 31, and the surface of the first flange 32 away from the inner panel 2 is connected to the outer panel 1, and the surface of the second flange 33 away from the inner panel 2 is connected to the outer panel 1.

[0041] Exemplarily, the first flange 32 and the second flange 33 may be connected to the outer panel 1 by welding.

[0042] Therefore, by providing the first flange 32 and the second flange 33 , a surface for connecting the reinforcing plate 3 and the outer panel 1 can be reserved, so that the reinforcing plate 3 and the outer panel 1 can be effectively connected, which is beneficial to improving the rigidity of the trunk lid assembly 100 .

[0043] According to the trunk lid assembly 100 of the embodiment of the present application, the groove 314 of the reinforcement plate 3 and the outer plate 1 form a cavity 35, and the first flange 32 and the second flange 33 are arranged at the opening 351 of the groove 314, so that the reinforcement plate 3 can be connected to the outer plate 1 through the first flange 32 and the second flange 33, and connected to the inner plate 2 through the body 31, so that when the trunk lid assembly 100 is subjected to external force, the force can be transmitted to the inner plate 2 and the outer plate 1, which is conducive to improving the structural strength and torsion resistance of the trunk lid assembly 100, and because the connection between the reinforcement plate 3 and the outer plate 1 is an effective connection, it is conducive to further improving the strength of the trunk lid assembly 100. In addition, when the outer plate 1 is subjected to a load, the load is transmitted to the reinforcement plate 3 through the first flange 32 and the second flange 33, and the cavity 35 can evenly distribute the load to the reinforcement plate 3, which can reduce local stress concentration, thereby facilitating the improvement of the bearing capacity and structural strength of the trunk lid assembly 100. Meanwhile, the reinforcing plate 3 having the groove 314 is helpful to reduce the deadweight of the trunk lid assembly 100 .

[0044] Please continue reading Figure 2 and Figure 3 In some embodiments, the first flange 32 and the second flange 33 can be respectively arranged on two opposite sides of the opening 351 in the first direction. Specifically, in the first direction, the first flange 32 can be arranged on one side of the opening 351, and the second flange 33 can be arranged on the other side of the opening 351. The extension direction of the first flange 32 is opposite to the extension direction of the second flange 33. The first direction can be the width direction of the reinforcing plate 3, that is, Figure 3 The X-axis direction is shown in .

[0045] Thus, the first flange 32 and the second flange 33 located on opposite sides of the opening 351 can be connected to the outer panel 1 so that the load on the outer panel 1 can be more evenly transferred to the reinforcing plate 3, thereby facilitating improving the structural strength of the trunk lid assembly 100.

[0046] Please continue reading Figure 2 and Figure 3 In some embodiments, the reinforcing plate 3 may further include a third flange 34. The third flange 34 is disposed at the periphery of the opening 351 and is located between the first flange 32 and the second flange 33. The third flange 34 is connected to the outer panel 1. Specifically, the first flange 32, the third flange 34 and the second flange 33 are sequentially disposed at the periphery of the opening 351, and the third flange 34 may be folded from the edge of the opening 351 in a direction away from the side wall of the body 31, and the surface of the third flange 34 away from the inner panel 2 may be connected to the outer panel 1.

[0047] Therefore, the reinforcing plate 3 can be connected to the outer panel 1 through the first flange 32, the second flange 33 and the third flange 34, so that the reinforcing plate 3 and the outer panel 1 have three connection positions, so that the connection between the reinforcing plate 3 and the outer panel 1 can be more reliable, and at the same time, it can also withstand loads from multiple directions, which is beneficial to improve the structural strength of the trunk lid assembly 100.

[0048] See also Figure 3 and Figure 4 , Figure 4 A partial schematic diagram of a trunk lid assembly provided for some embodiments of the present application. In some embodiments, a first connection hole 321 may be provided on the first flange 32, and the first flange 32 may be plug-welded to the outer panel 1 through the first connection hole 321. A second connection hole 331 may be provided on the second flange 33, and the second flange 33 may be plug-welded to the outer panel 1 through the second connection hole 331. Plug welding is a welding process, which refers to connecting two plates up and down, filling the first connection hole 321 and the second connection hole 331 with weld metal, melting the weld metal by melting welding, and connecting the two plates after the metal cools.

[0049] Therefore, the first flange 32 and the second flange 33 can be connected to the outer panel 1 through the first connecting hole 321 and the second connecting hole 331. The connection method is simple, which is beneficial to reducing the manufacturing cost of the trunk lid assembly 100, and can also ensure the connection strength between the reinforcing plate 3 and the outer panel 1.

[0050] Please continue reading Figure 3 and Figure 4 In some embodiments, the number of the first connection holes 321 can be multiple. The multiple first connection holes 321 are arranged at intervals on the first flange 32. The number of the second connection holes 331 is multiple. The multiple second connection holes 331 are arranged at intervals on the second flange 33. Therefore, by providing multiple first connection holes 321 and multiple second connection holes 331, the connection strength between the first flange 32 and the second flange 33 and the outer panel 1 can be ensured, which is conducive to improving the reliability of the connection between the reinforcing plate 3 and the outer panel 1.

[0051] Please continue reading Figure 3 and Figure 4 In some embodiments, the third flange 34 may be provided with a third connection hole 341. The third flange 34 is connected to the outer panel 1 by plug welding through the third connection hole 341. Thus, the first flange 32, the second flange 33 and the third flange 34 can all be connected to the outer panel 1 by plug welding, so that it is convenient for the staff to connect the reinforcing plate 3 and the outer panel 1, which is conducive to reducing the manufacturing cost of the trunk lid assembly 100. At the same time, the connection strength between the reinforcing plate 3 and the outer panel 1 can also be better improved.

[0052] Exemplarily, the number of the third connection holes 341 may be multiple, wherein the total number of the first connection holes 321, the second connection holes 331 and the third connection holes 341 may be ten, thereby ensuring the connection strength between the reinforcing plate 3 and the outer plate 1.

[0053] See also Figure 5 , Figure 5 A partial schematic diagram of a trunk lid assembly provided in some other embodiments of the present application. In some embodiments, the body 31 may be provided with a plurality of plug welding holes 311. The body 31 is plug welded to the inner panel 2 through the plug welding holes 311. Thus, the connection strength between the reinforcing plate 3 and the inner panel 2 can be ensured, and it is also helpful to reduce the manufacturing cost of the trunk lid assembly 100.

[0054] Please continue reading Figure 5 In some embodiments, the reinforcing plate 3 may further include an extension plate 36. The extension plate 36 is disposed between the first flange 32 and the second flange 33. A plurality of plug welding holes 311 are disposed at intervals around the circumferential direction of the body 31, and are partially located on the extension plate 36. Among them, the plurality of plug welding holes 311 may be disposed at the edge of the body 31. Thus, the edge of the reinforcing plate 3 may be connected to the inner plate 2, and the connection strength between the inner plate 2 and the reinforcing plate 3 may be ensured. At the same time, the cavity 35 may be maximized, which is beneficial to improving the structural strength of the reinforcing plate 3.

[0055] Please continue reading Figure 5 In some embodiments, the body 31 may be provided with a plurality of reinforcing ribs 312. The plug welding holes 311 are provided at the reinforcing ribs 312. The structural strength of the reinforcing plate 3 can be improved by providing a plurality of reinforcing ribs 312. The plug welding holes 311 are provided at the reinforcing ribs 312, so that the connection strength between the inner plate 2 and the reinforcing plate 3 can be better ensured.
