[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] Reference below Figure 1-Figure 5 A rear panel assembly 100 of a vehicle according to an embodiment of the present invention is described.

[0034] like Figure 1-Figure 5 As shown, the rear panel assembly 100 according to the embodiment of the present invention includes: a first plate body 1 and a second plate body 2 .

[0035] The first plate body 1 and the second plate body 2 jointly define a cavity structure 3; the lower end of the first plate body 1 has a connecting flange 13, the connecting flange 13 is connected to the second plate body 2, and the connecting flange 13 is located on the side of the second plate body 2 facing the interior of the vehicle.

[0036] Specifically, the first plate body 1 and the second plate body 2 are connected and jointly define a cavity structure 3. The cavity structure 3 can collapse and absorb energy during a collision. In addition, the cavity structure 3 can also enhance the torsional stiffness of the vehicle structure, which is beneficial to improving the collision performance of the vehicle.

[0037] The lower end of the first plate body 1 has a connecting flange 13, which is connected to the second plate body 2. The connecting flange 13 and the second plate body 2 can be connected by welding. For example, the first plate body 1 and the second plate body 2 can be connected by spot welding. The connecting flange 13 is located on the side of the second plate body 2 facing the interior of the vehicle, so that the overlap of the first plate body 1 and the second plate body 2 can be located inside the cab. The second plate body 2 itself can block rainwater, and there is no need to apply glue and seal the overlap between the first plate body 1 and the second plate body 2, thereby reducing the production cost and weight of the rear panel assembly 100, and speeding up the production cycle. Moreover, since there is no need for gluing and sealing, there is no problem of cracking, falling off or aging of the glue, which can significantly improve the watertightness of the rear panel assembly 100.

[0038] Therefore, by making the connecting flange 13 at the lower end of the first plate body 1 be located on the side of the second plate body 2 facing the interior of the vehicle, the overlapping portion of the first plate body 1 and the second plate body 2 can be located inside the cab, thereby eliminating the need for gluing and sealing treatment at the overlapping portion of the first plate body 1 and the second plate body 2. This can reduce the production cost of the rear panel assembly 100, reduce the weight of the rear panel assembly 100, and is beneficial to the lightweight design of the vehicle. It can also speed up the production cycle and improve production efficiency. In addition, since there is no need for gluing and sealing treatment, the watertight effect of the rear panel assembly 100 will not deteriorate with age, which is beneficial to improving the reliability of the rear panel assembly 100.

[0039] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, along the height direction of the rear enclosure assembly 100, the cavity structure 3 is located at the upper end of the connecting flange 13, and the connecting flange 13 has at least one protrusion 131, which protrudes in a direction away from the second plate body 2 to define a drainage channel 132 together with the second plate body 2, and the drainage channel 132 is connected to the cavity structure 3.

[0040] Specifically, along the height direction of the rear panel assembly 100, the height direction is Figure 1 In the Z direction shown, the connecting flange 13 is located at the lower end of the first plate body 1. The connecting flange 13 has at least one protrusion 131, which protrudes toward the direction away from the second plate body 2, so that the protrusion 131 and the second plate body 2 together define a drainage channel 132 connected to the cavity structure 3.

[0041] It is understandable that the rear panel assembly 100 is part of the vehicle body, and the vehicle body needs to undergo electrophoresis during the production process. Since the first plate 1 and the second plate 2 jointly define the cavity structure 3, during the subsequent process, if there is electrophoretic liquid remaining in the cavity structure 3, it will seriously affect the yield of the rear panel assembly 100. By making the raised portion 131 and the second plate 2 jointly define a drainage channel 132 connected to the cavity structure 3, the electrophoretic liquid remaining in the cavity structure 3 can be quickly discharged through the drainage channel 132 to reduce the risk of electrophoretic liquid remaining in the cavity structure 3, which is conducive to improving the yield.

[0042] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, there are multiple protrusions 131, and the multiple protrusions 131 are arranged at intervals along the width direction of the vehicle, and the width direction is perpendicular to the height direction.

[0043] Specifically, the plurality of raised portions 131 and the second plate body 2 together define a plurality of drainage channels 132. The plurality of raised portions 131 are arranged at intervals along the width direction of the vehicle, wherein the width direction is perpendicular to the height direction. Figure 1 In the Y direction shown, by having multiple protrusions 131, the electrophoretic fluid remaining in the cavity structure 3 can be quickly discharged to further reduce the risk of electrophoretic fluid remaining in the cavity structure 3. In addition, since the protrusions 131 are arranged at intervals along the width direction of the vehicle, the risk of electrophoretic fluid remaining in some corners of the cavity structure 3 can be reduced.

[0044] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the first plate body 1 includes: a first sub-plate body 11 and a second sub-plate body 12, the lower end of the first sub-plate body 11 has a connecting flange 13, one end of the second sub-plate body 12 is connected to the upper end of the first sub-plate body 11 and the other end of the second sub-plate body 12 extends toward the interior of the vehicle and is connected to the second plate body 2 to jointly define a cavity structure 3.

[0045] The first sub-plate 11 has two opposing ends along the height of the vehicle. The lower end of the first sub-plate 11 has a connecting flange 13. The upper end of the first sub-plate 11 is connected to one end of the second sub-plate 12. The other end of the second sub-plate 12 extends toward the interior of the vehicle and connects to the second plate 2. This arrangement optimizes the structure of the first plate 1 and allows the first and second plates 1 and 2 to jointly define a larger cavity structure 3, thereby improving the vehicle's collision performance and enhancing the torsional rigidity of the vehicle structure.

[0046] In some embodiments of the present invention, Figure 1-Figure 3As shown, the second plate body 2 includes: a third sub-plate body 21 and a fourth sub-plate body 22, the connecting flange 13 is connected to the third sub-plate body 21, at least part of the structure of the fourth sub-plate body 22 extends toward the interior of the vehicle, one end of the fourth sub-plate body 22 is connected to the third sub-plate body 21, and the other end of the fourth sub-plate body 22 is connected to the end of the second sub-plate body 12 away from the first sub-plate body 11.

[0047] Among them, along the height direction of the vehicle, the fourth sub-plate body 22 is arranged above the third sub-plate body 21, and part of the structure of the fourth sub-plate body 22 extends toward the interior of the vehicle, or the entire structure of the fourth sub-plate body 22 extends toward the interior of the vehicle, the lower end of the fourth sub-plate body 22 is connected to the upper end of the third sub-plate body 21, and the upper end of the fourth sub-plate body 22 is connected to the end of the second sub-plate body 12 away from the first sub-plate body 11, and the connecting flange 13 is connected to the third sub-plate body 21 (for example, but not limited to, welding connection). This arrangement can make the structural form of the second plate body 2 reasonable, and can make the first plate body 1 and the second plate body 2 jointly define a larger cavity structure 3, which is beneficial to improving the collision performance of the vehicle and can enhance the torsional stiffness of the vehicle structure.

[0048] In some embodiments of the present invention, Figure 2 As shown, the third sub-board body 21 has a connecting portion 211 , which is connected to the connecting flange 13 and is located at one end of the third sub-board body 21 close to the fourth sub-board body 22 .

[0049] Specifically, the third sub-panel 21 has a connecting portion 211 at one end near the fourth sub-panel 22, and the connecting flange 13 at the lower end of the first sub-panel 11 is connected (e.g., welded) to the connecting portion 211 of the third sub-panel 21. In other words, the connecting flange 13 at the lower end of the first sub-panel 11 is connected to the end of the third sub-panel 21 near the fourth sub-panel 22. This arrangement allows the overlapping position of the connecting flange 13 and the second panel 2 to be positioned midway along the height of the second panel 2, ensuring a reasonable overlapping position between the connecting flange 13 and the second panel 2 and significantly improving the watertightness of the rear panel assembly 100.

As some embodiments of the present application, the reinforcing bracket 4 is welded to the first plate body 1 and the second plate body 2. It should be noted that the first plate body 1 and the second plate body 2 can jointly define a larger cavity structure 3. By arranging the reinforcing bracket 4 in the cavity structure 3, the structural strength of the rear panel assembly 100 can be significantly improved, thereby significantly improving the rear collision performance of the vehicle, which is beneficial to improving the safety of the vehicle. In addition, such an arrangement can reduce the probability of abnormal noise generated by the first plate body 1 and the second plate body 2, which is beneficial to improving the NVH (noise, vibration and harshness) performance of the vehicle.
