[0036] In addition, the description of "first", "second", etc. in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0037] The present application provides a tailgate assembly.

[0038] In the embodiments of the present application, with reference to Figure 1 and Figure 2 The tailgate assembly is installed on a vehicle, the vehicle is provided with a door opening, and the tailgate assembly comprises:

[0039] a top door 10, the top door 10 is used to cover the side of the door opening away from the chassis of the vehicle;

[0040] a main door 20, the main door 20 is used to cover the side of the door opening close to the chassis;

[0041] The tailgate assembly has an open state and a closed state, when the tailgate assembly is in the closed state, the top door 10 and the main door 20 cooperate and cover the door opening; when the tailgate assembly is in the open state, the top door 10 and the main door 20 open the door opening.

[0042] The connection mode of the top door 10 and the vehicle body 60 can be hinge connection, when the hinge connection is adopted, the top door 10 can be hinge connected with the side of the vehicle body, so that the top door 10 rotates around the axis in the height direction of the vehicle body, thereby converting the top door 10 between the open state and the closed state; the connection mode of the top door 10 and the vehicle body 60 can also be buckle connection, so that the top door 10 is in the open state by opening the buckle and disassembling the top door 10.

[0043] The main door 20 can be a double door design, i.e. Figure 1 As shown, the main door 20 has two panels, which are rotatably connected to both sides of the vehicle body 60. The main door 20 can switch between an open and closed state by rotating. Alternatively, only one main door 20 can be provided, rotatably connected to any side of the vehicle body 60. The main door 20 can also be rotatably connected to the side of the vehicle body 60 closest to the chassis, in which case the main door 20 can switch between an open and closed state by flipping up and down.

[0044] In vehicles such as vans or light passenger vehicles, the opening area of ​​the tailgate is usually smaller than the cross-sectional area of ​​the interior space of the vehicle in the direction of travel. With the top door 10 installed, the opening area of ​​the tailgate can be made almost equal to the cross-sectional area of ​​the interior space of the vehicle in the direction of travel, allowing the vehicle to carry more cargo and improving its carrying capacity.

[0045] refer to Figure 1 and Figure 2 Optionally, the top door 10 is rotatably connected to the vehicle roof 61. This allows the top door 10 to rotate relative to the vehicle body 60 in the height direction of the vehicle body 60, switching between open and closed states. Figure 1 The diagram shows the tailgate in its open state when connected to the vehicle body 60 using this connection method. Since the tailgate's width in the vehicle's height direction is often smaller than its width in the vehicle's width direction when closed, therefore... Figure 1 The top door 10 is connected to the vehicle body 60 in the manner shown. When the top door 10 is open, less space is required behind the vehicle, making it easier to open the top door 10. The swivel connection can be via a hinge or a latch.

[0046] refer to Figure 1 Furthermore, the tailgate assembly also includes a push rod, which connects the tailgate 10 to the vehicle body 60. The push rod is used to keep the tailgate 10 in the open position. The push rod can be a gas spring rod, with one end connected to the vehicle body 60 and the other end connected to the tailgate 10. When the tailgate 10 is closed, the push rod is compressed and retracted into the vehicle body 60; when the tailgate 10 is open, the push rod extends, but the gas inside the push rod remains compressed to provide a certain thrust to the tailgate 10, keeping it open. The push rod can also be a rigid rod, with one end rotatably connected to the vehicle body 60 and the other end in a free state; when the tailgate 10 is closed, the push rod is retracted into the vehicle body 60; when the tailgate 10 is open, the user abuts the free end of the push rod against the tailgate 10 to keep the tailgate 10 open.

[0047] refer to Figures 2 to 6Optionally, a first sealing strip 30 is provided on the side of the top door 10 near the main door 20. When the tailgate assembly is closed, the first sealing strip 30 abuts against the main door 20. Since vehicles inevitably encounter rain and snow during use, to prevent rainwater from entering the vehicle body 60 and wetting the cargo inside, a sealing strip is provided to seal the gap between the top door 10 and the main door 20. When the top door 10 is closed, the first sealing strip 30 abuts against the main door 20, thus preventing water from flowing into the vehicle through the gap between the top door 10 and the main door 20, achieving a sealing effect.

[0048] refer to Figures 2 to 6 Optionally, a second sealing strip 90 is provided on the edge of the vehicle body 60 that forms the door opening; when the tailgate assembly is closed, the second sealing strip 90 abuts against the periphery of the tailgate assembly. The second sealing strip 90 abuts against the top door 10, preventing rainwater from flowing into the vehicle through the mating gap between the top door 10 and the vehicle body 60. At the same time, the second sealing strip 90 also abuts against the main door 20, preventing rainwater from flowing into the vehicle through the mating gap between the main door 20 and the vehicle body 60, which further increases the waterproofness of the tailgate.

[0049] refer to Figure 4 and Figure 6 Optionally, the first sealing strip 30 includes a first body 31 and a first overlapping portion 32, with the first overlapping portion 32 disposed at both ends of the first body 31. The thickness of the first overlapping portion 32 in the thickness direction of the top door 10 is less than the thickness of the first body 31 in the thickness direction of the top door 10. When the tailgate assembly is in the closed state, the first overlapping portion 32 overlaps with the second sealing strip 90. The thickness of the first overlapping portion 32 is smaller than the thickness of the first body 31. On the one hand, this allows the first body 31 to maintain an interference fit in the fitting gap between the top door 10 and the main door 20, providing sufficient sealing effect. On the other hand, it reduces the squeezing effect of the first overlapping portion 32 on the second sealing strip 90, preventing the second sealing strip 90 from causing a fitting gap between itself and the top door 10 or the vehicle body due to deformation, thereby improving the waterproof effect.

[0050] refer to Figure 4 and Figure 6 Optionally, a third sealing strip 70 is also provided on the side of the top door 10 near the main door 20. The third sealing strip 70 is arranged parallel to the first sealing strip 30. When the tailgate assembly is closed, the third sealing strip 70 abuts against the main door 20. The third sealing strip 70 and the first sealing strip 30 can form a double seal together to improve waterproofing.

[0051] refer to Figure 1 , Figure 4 and Figure 5Optionally, the main door 20 includes a first side door 21 and a second side door 22. The first side door 21 and the second side door 22 are rotatably connected to the vehicle body on both sides in the y-axis direction. A fourth sealing strip 80 is provided on the first side door 21. When the tailgate assembly is in the closed state, the fourth sealing strip 80 abuts against the edge of the second side door 22. The first side door 21 and the second side door form a double-door configuration, which allows the tailgate to occupy less space when opened, improving ease of use. The fourth sealing strip 80 seals the gap between the first side door 21 and the second side door 22, resulting in better tailgate sealing.

[0052] refer to Figure 1 , Figure 4 and Figure 5 Optionally, the fourth sealing strip 80 includes a second body 81 and a second overlapping portion 82. The second overlapping portion 82 is disposed at both ends of the second body 81. When the tailgate assembly is in the closed state, the second overlapping portion 82 disposed at the end of the body near the chassis overlaps with the second sealing strip 90, and the second overlapping portion 82 disposed at the end of the body away from the chassis overlaps with the first sealing strip 30. The thickness of the second overlapping portion 82 in the thickness direction of the first side door 21 is less than the thickness of the second body 81 in the thickness direction of the first side door 21. The thickness of the second overlapping portion 82 is less than the thickness of the second main body 81. On the one hand, this reduces the squeezing effect of the second overlapping portion 82 on the first sealing strip 30, preventing deformation of the first sealing strip 30 and thus avoiding gaps between the first sealing strip 30 and the top door 10 or the main door 20. On the other hand, it also reduces the squeezing effect of the second overlapping portion 82 on the second sealing strip 90, preventing deformation of the second sealing strip 90 and thus avoiding gaps between the second sealing strip 90 and the main door 20 or the vehicle body, thereby improving waterproofing.

[0053] refer to Figure 2Optionally, the top door 10 is provided with a first locking part, and the main door 20 is provided with a second locking part; when the tailgate assembly is in the closed state, the first locking part and the second locking part are locked together. The locking of the first locking part and the second locking part can prevent relative movement between the top door 10 and the main door 20. In this way, when the main door 20 is closed, it can be ensured that the top door 10 will not open, which improves the strength of the tailgate when it is closed and prevents the tailgate from accidentally opening under the pressure of goods. The first locking part can be a lock body 50, and the second locking part can be a retaining ring 40; when the retaining ring 40 is engaged with the lock body 50, the top door 10 is fixed by the main door 20. The first locking part can also be a pin movably connected to the top door 10, and the pin can move along its length direction; the second locking part can be a pin hole corresponding to the pin position when the tailgate is closed; the extension direction of the pin is in the direction of gravity, and when the tailgate is closed, the pin engages with the pin hole, thereby preventing relative movement between the top door 10 and the main door 20. In addition, locking structures can be independently installed between the main door 20 and the vehicle body 60, as well as between the top door 10 and the vehicle body 60, to improve the strength when the tailgate is closed.

[0054] refer to Figure 2 Optionally, the first locking part is configured as a retaining ring 40, and the second locking part is configured as a lock body 50. The lock body 50 is located on the main door 20, so that when the top door 10 does not have other locking structures, both locking and unlocking of the top door 10 can be controlled by the main door 20. Since the top door 10 usually only needs to be opened when the main door 20 is open, unlocking the top door 10 at the main door 20 is more convenient for the user. Furthermore, the lock body 50 can be linked with other locking structures of the main door 20, allowing both the main door 20 and the top door 10 to be unlocked by unlocking only one point, improving the ease of use of the tailgate assembly.

[0055] refer to Figure 2 Optionally, at the junction of the top door 10 and the main door 20, the main door 20 is located on the side of the top door 10 away from the vehicle body 60. In this way, when the main door 20 is closed, it can prevent the top door 10 from opening. Especially when the top door 10 is rotatably connected to the side of the vehicle body 60 away from the chassis, the rotatable connection structure of the top door 10 and the main door 20 can restrict the movement of the top door 10 from both ends, preventing the top door 10 from being accidentally pushed open by cargo.

[0056] refer to Figure 1Optionally, the side of the top door 10 that mates with the main door 20 is configured as a first side 11, and the side of the main door 20 that mates with the top door 10 is configured as a second side 23. The first side 11 arches away from the chassis, and the second side 23 matches the first side 11. This ensures that when the rainwater flows through the top door 10 and the main door 20 at their mating position (i.e., where the first side 11 and the second side 23 are located), rainwater will be guided by the first side 11 or the second side 23 to flow towards the side of the vehicle, thereby flowing into the drainage channel provided on the side of the vehicle and further towards the vehicle chassis. This prevents rainwater from accumulating at the mating point of the top door 10 and the main door 20.

[0057] refer to Figure 1 Optionally, a handle is provided on the side of the top door 10 facing the vehicle body 60. The handle is used to open the top door 10. When the top door 10 is rotatably connected to the vehicle body 60 and switches between open and closed states by rotation, the handle for opening the top door 10 is located on the side of the top door 10 facing the vehicle body 60, making it convenient for the user to operate the top door 10. In particular, when the top door 10 is rotatably connected to the side of the vehicle body 60 away from the chassis, and the top door 10 is opened by lifting it upwards, if the handle is located on the side of the top door 10 away from the vehicle body 60, the handle will rise continuously as the top door 10 is lifted upwards, eventually completely away from the user standing on the ground or inside the vehicle, making it inconvenient for the user to operate. However, when the handle is located on the side of the top door 10 facing the vehicle body 60, the handle faces the operator after the top door 10 is opened, making it convenient for the user to operate.

[0058] The present invention also proposes a vehicle including a tailgate assembly. The specific structure of the tailgate assembly is as described in the above embodiments. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0059] Vehicles on the market often come in two versions for the same model: a standard version and a high-roof version. The difference lies in the roof height; the high-roof version has a higher roof, increasing cargo space. However, to save costs, the high-roof version shares the same tailgate mold as the standard version. Creating a new tailgate mold for the high-roof version would incur millions of dollars in additional costs, significantly increasing production costs. This cost-saving measure of sharing the tailgate results in a smaller tailgate size for the high-roof version, with the tailgate opening area much smaller than the cross-sectional area of ​​the vehicle's interior space in the direction of travel. Consequently, while the high-roof version offers more cargo space than the standard version, the maximum size of cargo that can be transported is roughly the same. This drastically reduces the cargo capacity of the high-roof version.

[0060] refer to Figure 1 The top door 10 can work in conjunction with the main door 20 to further enlarge the tailgate opening of the high-roof version vehicle, thereby increasing its carrying capacity. Meanwhile, the main door 20 can be shared with the standard version vehicle, reducing the manufacturing cost of the high-roof version. Especially when the vehicle length exceeds 5m, there is a greater probability that the vehicle will transport larger cargo; adding or removing the top door 10 can better meet user needs.

[0061] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
