[0026] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0027] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0028] In some vehicles with double-opening tailgates in the related art, in order to allow both tailgates to be opened independently, a certain gap is left between the two tailgates, which makes it easy for water and dust to enter the vehicle, and the sound insulation performance of the vehicle is also poor.

[0029] Therefore, an embodiment of the present application provides a tailgate assembly and a vehicle, wherein a seal is provided between the first tailgate and the second tailgate, so that when the first tailgate and the second tailgate are both in a closed state, the first tailgate and the second tailgate can be effectively sealed, which can prevent water and dust from entering the interior of the vehicle to a certain extent and can achieve a certain sound insulation effect.

[0030] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Please combine Figures 1 to 4 , Figure 1 A schematic diagram of a partial structure of a vehicle provided in an embodiment of the present application, Figure 2 for Figure 1 A schematic diagram of the structure from another perspective. Figure 3 for Figure 1 A schematic structural diagram of a first partial structure of the structure shown, Figure 4 for Figure 1 As shown in the figure, the present embodiment provides a back door assembly, including a first back door 1 and a second back door 2, wherein the first back door 1 and the second back door 2 can be arranged along the width direction of the vehicle or along the up-down direction, and the first back door 1 and the second back door 2 are both used for active connection with the vehicle body.

[0032] In a specific implementation of this embodiment, the first back door 1 and the second back door 2 are arranged in the up-down direction, and the first back door 1 is located above the second back door 2, that is, the first back door 1 can be understood as an upper back door, and the second back door 2 can be understood as a lower back door. The following takes the example that the first back door 1 and the second back door 2 are arranged in the up-down direction, and the first back door 1 is located above the second back door 2 as an example to describe this embodiment in detail.

[0033] It should be noted that in the back door assembly provided in this embodiment, the first back door 1 and the second back door 2 can be opened or closed independently. For example, when it is necessary to place some small objects in the height direction of the vehicle, only the second back door 2 located below can be opened without opening the first back door 1, and the objects can be pushed in directly through the inner surface of the second back door 2; for another example, it is now popular to sell things in the trunk. In this case, only the first back door 1 can be opened, and the things to be sold can be hung on the first back door 1 for display and sale without opening the second back door 2. Here, the scenarios in which the first back door 1 and the second back door 2 are opened independently are not listed one by one.

[0034] Among them, the first tailgate 1 includes a sheet metal component 131 and an outer decorative panel 132, the outer decorative panel 132 is detachably connected to the sheet metal component 131, and is used to form part of the exterior appearance of the vehicle, wherein the sheet metal component 131 is connected to the door top cover 11, and the sheet metal component 131 includes an inner sheet metal part 1311 and an outer sheet metal part 1312, the inner sheet metal part 1311 includes an inner sheet metal 1313 and a first connecting portion 1314, the outer sheet metal part 1312 includes an outer sheet metal 1315 and a second connecting portion 1316, when the first tailgate 1 is in a closed state, the inner sheet metal 1313 is located at the front side of the outer sheet metal 1315, the first connecting portion 1314 is located at the lower side of the second connecting portion 1316, and the first connecting portion 1314 and the second connecting portion 1316 are welded together to connect the inner sheet metal part 1311 and the outer sheet metal part 1312 together.

[0035] It is understandable that when the first back door 1 and the second back door 2 can be opened independently without being affected by each other, inevitably, a gap will be formed between the first back door 1 and the second back door 2. Therefore, in order to prevent dust from the outside from entering the interior of the vehicle through the gap, the back door assembly provided in this embodiment should also include a sealing member 3, which is installed on one of the first back door 1 and the second back door 2, and is pressed against the other of the first back door 1 and the second back door 2 when both the first back door 1 and the second back door 2 are in a closed state. Specifically, the sealing member 3 is installed on the first back door 1, and is pressed against the top of the second back door 2 when both the first back door 1 and the second back door 2 are in a closed state. In this way, the first back door 1 and the second back door 2 can be sealed by setting the sealing member 3, so as to prevent water and dust from the outside from entering the interior of the vehicle to a certain extent, and at the same time, it can play a certain sound insulation effect and improve the user experience of the vehicle.

[0036] Of course, in some usage scenarios, the seal 3 cannot block all external dust or water from entering the vehicle. In this case, in order to prevent external water from entering the vehicle, a downwardly recessed water guide groove 2111 can be formed on the second back door 2, and when the first back door 1 and the second back door 2 are both in a closed state, the water guide groove 2111 is located in front of the seal 3. In this way, by providing the water guide groove 2111, external water can flow into the water guide groove 2111 and flow to the outside of the vehicle through the guidance of the water guide groove 2111.

[0037] It should be noted that the above-mentioned "the water guide groove 2111 is located in front of the seal 3" can be understood as that the water guide groove 2111 is located on the side of the seal 3 closer to the front of the vehicle. At this time, when the seal 3 cannot block the water, the external water can flow into the water guide groove 2111, and then the water flows to the outside of the vehicle through the guiding effect of the water guide groove 2111.

[0038] For example, in some rainstorms, there is a lot of water outside. At this time, when the seal 3 cannot block all the water outside the vehicle, the water outside the vehicle can be guided to a certain extent by the combined effect of the water guide groove 2111.

[0039] When the seal 3 is installed on the first back door 1 and the first back door 1 is in a closed state, the seal 3 may interfere with the second back door 2 during the process of opening or closing the second back door 2. Therefore, in order to avoid this phenomenon, a relief portion 21 may be formed on the top of the second back door 2. When the first back door 1 is in a closed state, the relief portion 21 is used to avoid the seal 3 during the process of opening or closing the second back door 2. In this way, by forming the relief portion 21 on the top of the second back door 2, when the first back door 1 is in a closed state, the top of the second back door 2 can be prevented from interfering with the seal 3 when the second back door 2 is closed or opened. On the one hand, the convenience of opening or closing the second back door 2 can be improved, and the use performance of the whole vehicle can be improved; on the other hand, the surface wear of the seal 3 can be avoided to a certain extent, so that the seal 3 maintains a good sealing performance.

[0040] The water guide groove 2111 is formed on the avoidance portion 21 .

[0041] In order to ensure that the seal 3 can effectively seal between the first back door 1 and the second back door 2 when both are in the closed state, as an optional embodiment, a seal portion 22 may be formed at the top of the second back door 2, and the seal 3 is pressed against the seal portion 22 when both are in the closed state; when the second back door 2 is in the closed state, the seal portion 22 is located at the rear side of the avoidance portion 21, and the top of the seal portion 22 is higher than the top of the avoidance portion 21. In this way, by forming the seal portion 22, the seal 3 can effectively seal between the first back door 1 and the second back door 2, and by limiting the position of the top of the seal portion 22 and the top of the avoidance portion 21, not only the sealing performance of the seal 3 is ensured, but also no interference is generated between the seal 3 and the second back door 2 during the opening or closing of the second back door 2.

[0042] Specifically, the sealing portion 22 includes a first sealing surface 221 and a second sealing surface 222 that are angled and connected to each other. The sealing member 3 is pressed against the intersection of the first sealing surface 221 and the second sealing surface 222 when the first back door 1 and the second back door 2 are both in a closed state. The avoidance portion 21 includes an avoidance surface 211, and the second sealing surface 222 is connected between the first sealing surface 221 and the avoidance surface 211. When the second back door 2 is in a closed state, the first sealing surface 221 is higher than the avoidance surface 211. In this way, during the process of opening or closing the second back door 2, the avoidance portion 21 can avoid the sealing member 3, so that the first back door 1 and the second back door 2 can be opened or closed independently, and the sealing performance between the first back door 1 and the second back door 2 is better.

[0043] In order to improve the structural compactness of the vehicle, in some optional embodiments, the first sealing surface 221 extends in the horizontal direction, and the avoidance surface 211 and the first sealing surface 221 are arranged in parallel. In this way, the vehicle has a stronger structural compactness in the height direction.

[0044] The water guide groove 2111 is formed on the avoidance surface 211, and part of the groove side wall of the water guide groove 2111 is formed on the second sealing surface 222. In this way, part of the groove side wall of the water guide groove 2111 can be formed with the help of the structure of the second sealing surface 222, which can reduce the manufacturing cost of the second back door 2; and a plurality of spaced water guide holes (not shown in the figure) can be formed on the bottom wall of the water guide groove 2111.

[0045] The bottom of the second rear door 2 is provided with a hole for allowing the flow of swimming liquid and the like, and the water flowing out through the water guide hole can flow into the hole and finally flow out of the vehicle.

[0046] Please combine Figure 5 , Figure 5 A cross-sectional view of a seal in a back door assembly provided in an embodiment of the present application. As shown in the figure, in some embodiments, the seal 3 includes a seal body 31, the outer surface of the seal body 31 is a circular arc surface, and the seal portion 22 also includes a rounded structure 223 formed at the intersection of the first sealing surface 221 and the second sealing surface 222; the seal body 31 presses against the rounded structure 223 when both the first back door 1 and the second back door 2 are in a closed state. By making the contact between the seal body 31 and the seal portion 22 a rounded structure 223, the seal 3 can effectively seal between the first back door 1 and the second back door 2.

[0047] Furthermore, in order to install the seal 3, the seal 3 may also include a connecting portion 32 and an extending portion 33, both of which are connected to the sealing body 31, and the connecting portion 32 extends between the exterior panel 132 and the sheet metal assembly 131 to be connected to the sheet metal assembly 131; the extending portion 33 is connected to the side of the sealing body 31, and extends to the exterior panel 132 to be connected to the exterior panel 132.

[0048] Among them, the connecting part 32 includes a first connecting section 321, a second connecting section 322 and a third connecting section 323. The first connecting section 321 is connected to the sealing body 31 and extends between the exterior trim panel 132 and the sheet metal assembly 131. The second connecting section 322 is connected to the first connecting section 321 and extends toward one side of the outer sheet metal 1315. The third connecting section 323 is connected to the second connecting section 322 and extends toward the second connecting part 1316 to have an interference fit with the second connecting part 1316.

[0049] It is understandable that when installing the seal 3, in order to facilitate the assembly of the seal 3, a deformation notch 324 can be formed on the third connecting section 323. By setting the deformation notch 324, the assembly efficiency between the seal 3 and the sheet metal component 131 can be improved.

[0050] In addition, a plurality of sealing lips 34 are formed on the sealing body 31 and are spaced apart from each other. The plurality of sealing lips 34 are located on the side of the first connection portion 1314 that is away from the second connection portion 1316 , and the plurality of sealing lips 34 are interference fit with the first connection portion 1314 . In this way, the seal 3 can be installed on the sheet metal component 131 .

[0051] Among them, during the assembly process of the tailgate assembly, when assembling the first tailgate 1, the inner sheet metal 1311 and the outer sheet metal 1312 are first welded together and assembled to the vehicle body, and then the seal 3 is installed on the sheet metal component 131. Finally, the exterior trim 132 is connected to the outside of the outer sheet metal 1312 by snap-fitting or screwing to fix the seal 3. In this way, the assembly of the first tailgate 1 is completed.

[0052] It is understandable that when the first back door 1 is in a closed state, the second back door 2 will inevitably come into contact with the seal 3 during the process of opening or closing the second back door 2. In order to prevent the seal 3 from breaking when in contact with the second back door 2, the seal 3 may have a larger deformation amount. Thus, in some optional embodiments, a cavity 35 may be formed inside the seal 3. In this way, the service life of the seal 3 can be extended by providing the cavity 35.

[0053] It should be noted that the above-mentioned cavity 35 is disposed in the sealing body 31 , and there may be a plurality of cavities 35 . Here, the number of cavities 35 is not specifically limited.

[0054] This embodiment further provides a vehicle, comprising a vehicle body and the back door assembly in the above embodiment. The structure of the back door assembly has been described in detail in the above embodiment, and will not be described in detail here.

[0055] It should be noted that the vehicle provided in this embodiment should also include other modules or components, which are not introduced one by one here.

[0056] The above contents are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
