[0031] 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.

[0032] 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.

[0033] In the related art, a vehicle includes a body and a tailgate, the tailgate includes a first sub-door and a second sub-door, one end of the first sub-door is rotationally connected to the body, and the other end of the first sub-door is rotationally connected to the second sub-door so that the second sub-door can rotate relative to the first sub-door. Specifically, during the opening process of the tailgate, the second sub-door can be folded inward or opened outward relative to the first sub-door.

[0034] However, in the above-mentioned vehicle, when the second sub-door is folded inward compared to the first sub-door, the sealing between the first sub-door and the second sub-door cannot be guaranteed, which may cause external rainwater to enter the rear passenger space through the gap formed between the first sub-door and the second sub-door, affecting the riding experience of the passengers in the vehicle, and thus making the overall performance of the vehicle poor.

[0035] Therefore, the embodiment of the present application provides a back door assembly and a vehicle, when the back door is in a closed state, a static seal between the first sub-door and the second sub-door can be achieved through the first sealing member; when the back door is opened to a first preset angle and the second sub-door is folded inwardly to a second preset angle relative to the first sub-door, a dynamic seal between the second sub-door and the second sub-door can be achieved through the second sealing member. In this way, the sealing performance of the vehicle provided by the embodiment of the present application is good in different states, and the use performance of the vehicle provided by the embodiment of the present application is good.

[0036] Hereinafter, the embodiments of the present application will be described in detail with reference to the accompanying drawings and specific implementation methods.

[0037] See also Figure 1 , Figure 1 A schematic diagram of a partial structure of a vehicle provided in an embodiment of the present application. As shown in the figure, the present embodiment provides a back door assembly, including a back door 1, including a first sub-door 11 and a second sub-door 12, one end of the first sub-door 11 is used to be rotatably connected to the vehicle body so that the back door 1 as a whole can be closed or opened relative to the vehicle body, and the other end of the first sub-door 11 is rotatably connected to the second sub-door 12 so that the second sub-door 12 can be folded inwardly or opened outwardly relative to the first sub-door 11 when the back door 1 is in the process of opening or in the open state.

[0038] It is understandable that due to the rotational connection between the first sub-door 11 and the second sub-door 12, a connection gap will be formed between the first sub-door 11 and the second sub-door 12. When the tailgate 1 is in a closed state and an open state, external dust and liquid may enter the interior of the vehicle through the connection gap.

[0039] Therefore, the back door assembly provided in this embodiment further includes a first seal 2, one end of which is connected to the first sub-door 11, and when the back door 1 is closed relative to the vehicle body, the other end of the first seal 2 is crimped to the second sub-door 12. In this way, by setting the first seal 2, when the back door 1 is closed relative to the vehicle body, the connection gap formed between the first sub-door 11 and the second sub-door 12 can be sealed to prevent external dust and liquid from entering the interior of the vehicle to a certain extent, that is, static sealing between the first sub-door 11 and the second sub-door 12 can be achieved.

[0040] Among them, the connection relationship between the first seal 2 and the first sub-door 11 can be bonding, and in the length direction of the vehicle, the front end of the first seal 2 is connected to the first sub-door 11, and when the tailgate 1 is closed relative to the vehicle body, the rear end of the first seal 2 is crimped to the second sub-door 12.

[0041] It should be noted that the length direction of the vehicle is Figure 1 The xx-axis direction is consistent.

[0042] In some specific embodiments, the first sub-door 11 includes a first outer panel 111 and a first inner panel 112; the surface of the first outer panel 111 forms part of the appearance of the back door assembly, and the first inner panel 112 is connected to the inner side of the first outer panel 111; one end of the first sealing member 2 is connected to the first outer panel 111. The first outer panel 111 and the first inner panel 112 are both sheet metal parts, and the first outer panel 111 and the first inner panel 112 can be welded together.

[0043] Specifically, the first outer panel 111 includes a first plate body 1111 and a first folding portion 1112 connected together, the surface of the first plate body 1111 forms a partial appearance surface of the back door assembly, and the first folding portion 1112 is folded inward compared to the first plate body 1111 and covers the end of the first inner panel 112; one end of the first seal 2 is connected to the first plate body 1111, and the connection between the first seal 2 and the first plate body 1111 can also be that one end of the first seal 2 is crimped to the first plate body 1111.

[0044] It should be noted that, in the present embodiment, part of the structure of the first sub-door 11 is formed as part of the vehicle body ceiling. Therefore, for the vehicle body ceiling, its interior should be provided with corresponding decorative parts to form the wall surface of the interior space of the vehicle body.

[0045] Therefore, in some embodiments, the first sub-door 11 further includes an interior panel (not shown) connected to the inner side of the first inner panel 112. The interior panel can be made of materials such as plastic.

[0046] Please combine Figure 2 , Figure 2 A cross-sectional view of the first seal in the tailgate assembly provided in an embodiment of the present application. In some embodiments, the first seal 2 includes a first seal body 21, one end of the first seal body 21 is crimped to the first plate body 1111; when the tailgate 1 is closed relative to the vehicle body, the other end of the first seal body 21 is crimped to the second sub-door 12, that is, when the tailgate 1 is closed relative to the vehicle body, the front end of the first seal body 21 is crimped to the first plate body 1111, and the rear end of the first seal body 21 is crimped to the second sub-door 12. In this way, when the tailgate 1 is in a closed state, the first sub-door 11 and the second sub-door 12 can be effectively sealed.

[0047] From the above, it can be seen that the first seal 2 is connected to the first sub-door 11. Therefore, in order to improve the connection efficiency between the first seal 2 and the first sub-door 11, a corresponding limiting structure can be set on the first seal 2 to limit the relative position between the first seal 2 and the first sub-door 11.

[0048] Specifically, the first sealing member 2 further includes a limiting portion 22 connected to the first sealing body 21; the limiting portion 22 is located between the first sub-door 11 and the second sub-door 12, and the limiting portion 22 is arranged close to the first sub-door 11. The setting of the limiting portion 22 can limit the position of the first sealing member 2 and the first sub-door 11 in the length direction of the vehicle, so as to improve the connection efficiency between the first sealing member 2 and the first sub-door 11.

[0049] One end of the limiting portion 22 is connected to the first sealing body 21 , and the other end of the limiting portion 22 extends toward the interior of the vehicle. When the tailgate 1 is in a closed state, the extending direction of the limiting portion 22 is consistent with the height direction of the vehicle.

[0050] It should be noted that the height direction of the vehicle is Figure 1 The direction of the zz axis is consistent.

[0051] However, in some situations, the first sealing member 2 alone is not sufficient to seal between the first sub-door 11 and the second sub-door 12. For example, when the back door 1 is in an open state and the second sub-door 12 is folded inward relative to the first sub-door 11, the second sub-door 12 has been detached from the first sealing member 2. Therefore, the first sealing member 2 cannot seal between the first sub-door 11 and the second sub-door 12 in this situation.

[0052] Therefore, the tailgate assembly provided in this embodiment also includes a second seal 3, one end of which is connected to the second sub-door 12; when the tailgate 1 is opened to a first preset angle relative to the vehicle body, and the second sub-door 12 is folded inward at a second preset angle relative to the first sub-door 11, the other end of the second seal 3 is pressed against the interior panel of the first sub-door 11.

[0053] Thus, in this use state of the back door 1, the second sealing member 3 can seal between the first sub-door 11 and the second sub-door 12, so that when the back door 1 is opened and the second sub-door 12 is folded inward relative to the first sub-door 11, it can prevent external dust and liquid from entering the vehicle interior through the connection gap between the first sub-door 11 and the second sub-door 12 to a certain extent. In this way, dynamic sealing between the first sub-door 11 and the second sub-door 12 can be achieved, thereby improving the use performance of the vehicle.

[0054] It should be noted that the first preset angle is greater than or equal to 65 degrees, and the second preset angle is greater than or equal to 50 degrees and less than or equal to 60 degrees.

[0055] That is to say, the opening angle of the back door 1 can be 65 degrees, 66 degrees, 67 degrees, 68 degrees, etc. The maximum opening angle of the back door 1 is determined according to the control logic for controlling the back door 1, and is not limited here.

[0056] Meanwhile, the folding angle of the second sub-door 12 relative to the first sub-door 11 can be 50 degrees, 51 degrees, 52 degrees, 53 degrees, 54 degrees, 55 degrees, 56 degrees, 57 degrees, 58 degrees, 59 degrees, 60 degrees, etc. Here, the folding angle of the second sub-door 12 relative to the first sub-door 11 is not specifically limited.

[0057] In some specific embodiments, the second sub-door 12 includes a second outer panel 121 and a second inner panel 122; the surface of the second outer panel 121 forms part of the exterior surface of the back door assembly; the second inner panel 122 is connected to the inner side of the second outer panel 121, and the surface of the second inner panel 122 is used to form part of the inner wall surface of the interior space of the vehicle body; the second sealing member 3 is pressed against the second outer panel 121.

[0058] In order to realize the connection between the second sealing member 3 and the second sub-door 12, in this embodiment, the second sub-door 12 further includes a mounting plate 123; one end of the mounting plate 123 is connected to the second inner plate 122, and the other end of the mounting plate 123 is connected to one end of the second sealing member 3, and the other end of the mounting plate 123 is not in contact with the second inner plate 122. In this way, by setting the mounting plate 123, the structural strength of the second sub-door 12 can be avoided to a certain extent due to the connection between the second sealing member 3 and the second sub-door 12. Therefore, by setting the mounting plate 123, the structural strength of the second sub-door 12 can be improved, and then the structural strength of the back door assembly provided by this embodiment can be improved.

[0059] Please continue to combine Figure 3 , Figure 3 A schematic diagram of a partial structure of a back door assembly provided in an embodiment of the present application. As shown in the figure, in some specific embodiments, the second outer plate 121 includes a second plate body 1211 and a second folding portion 1212 connected together, the surface of the second plate body 1211 forms a part of the appearance surface of the back door assembly, the second folding portion 1212 is folded inwardly compared to the second plate body 1211 and covers the end of the second inner plate 122; the second sealing member 3 is pressed against the second folding portion 1212.

[0060] Please combine Figure 4 , Figure 4A cross-sectional view of the second seal in the back door assembly provided in the embodiment of the present application. In order to connect the second seal 3 to the mounting plate 123, in some embodiments, the second seal 3 includes a second seal body 31 and a connecting portion 32, the second seal body 31 is pressed against the second outer plate 121; the connecting portion 32 is connected to the second seal body 31, and a mounting groove 33 is formed between the connecting portion 32 and the second seal body 31, and the end of the mounting plate 123 extends into the mounting groove 33 and is connected to the mounting groove 33. Specifically, the connection between the end of the mounting plate 123 and the side wall of the mounting groove 33 can also be connected together by bonding.

[0061] In order to enable the second sealing member 3 to be pressed against the interior panel of the first sub-door 11, in some embodiments, the second sealing member 3 also includes a sealing portion 34 connected to the second sealing body 31, and the sealing portion 34 and the connecting portion 32 are respectively arranged on opposite sides of the sealing body; when the tailgate 1 is opened to a first preset angle relative to the vehicle body, and the second sub-door 12 is folded inward at a second preset angle relative to the first sub-door 11, the sealing portion 34 is pressed against the first sub-door 11.

[0062] In a specific implementation of this embodiment, the connecting portion 32 and the sealing portion 34 are both lips extending outward from the second sealing body 31. Here, the specific shapes of the connecting portion 32 and the sealing portion 34 are not limited.

[0063] In some optional embodiments, in order to enhance the sealing performance of the second seal 3, a cavity 311 is formed inside the second sealing body 31. The setting of the cavity 311 can increase the deformation of the second seal 3. In this way, when the second seal 3 is pressed against the interior panel of the first sub-door 11, the fit will be more reliable, so as to effectively seal the first sub-door 11 and the second sub-door 12.
