[0003] The existing tailgate assembly has uneven overlapping surfaces at the junction of the tailgate sheet metal components and the tailgate window frame, resulting in an uneven transition. When the tailgate assembly is closed, there is a problem with the seal between the overlapping surfaces and the door frame sealing strip, affecting the sealing performance of the tailgate assembly. Utility Model Content

[0004] In view of this, this application aims to provide a tailgate assembly to improve the sealing performance of the tailgate assembly.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A tailgate assembly includes a tailgate sheet metal assembly and a window frame connected above the tailgate sheet metal assembly; The longitudinal beam of the window frame and the sheet metal assembly of the rear door are welded together, and the side of the connection facing the front of the vehicle is covered with a decorative panel. The decorative panel has a first sealing surface facing the front of the vehicle. The first sealing surface, the front side of the window frame, and the second sealing surface on the tailgate sheet metal assembly are coplanar and are all used to abut against the door frame sealing strip on the vehicle body.

[0006] Furthermore, the tailgate sheet metal assembly includes a tailgate body and a reinforcing plate connected to the top of the tailgate body; The longitudinal beam is welded to the reinforcing plate, and the decorative panel covers the front side of the reinforcing plate.

[0007] Furthermore, the longitudinal beam has a first groove on the side facing forward of the vehicle, and the decorative panel has a first overlapping portion that overlaps the longitudinal beam; The first overlapping portion is embedded in the first groove, and the side of the first overlapping portion facing the front of the vehicle constitutes the upper part of the first sealing surface.

[0008] Furthermore, along the left-right direction of the entire vehicle from the inside to the outside, the upper end of the first overlapping portion slopes downward; and / or, Along the vertical direction of the vehicle, from top to bottom, the depth of the first groove gradually increases.

[0009] Furthermore, a second groove is provided on the side of the tailgate body facing the front of the vehicle, and the decorative panel has a second overlapping portion that overlaps the tailgate body; The second overlapping portion is fitted into the second groove, and the side of the second overlapping portion facing the front of the vehicle constitutes the lower part of the first sealing surface.

[0010] Furthermore, along the left-right direction of the entire vehicle from the inside to the outside, the lower end of the second overlapping portion slopes downward; and / or, Along the vertical direction of the vehicle, from bottom to top, the depth of the second groove gradually increases.

[0011] Furthermore, the decorative panel and the reinforcing plate are snapped together.

[0012] Furthermore, a sealing portion is provided between the decorative panel and the reinforcing plate. The sealing portion extends along the vertical direction of the vehicle and has a first extension portion extending to the rear side of the first overlapping portion and a second extension portion extending to the rear side of the second overlapping portion.

[0013] Furthermore, the window frame is made of extruded aluminum; and / or, The decorative panel is integrally molded using an injection molding process.

[0014] Compared with related technologies, this application has the following advantages: (1) The tailgate assembly described in this application covers the connection part of the longitudinal beam and the tailgate sheet metal assembly with a decorative panel, so that the first sealing surface, the front side of the window frame and the second sealing surface on the decorative panel are set together, which can better press against the door frame sealing strip on the vehicle body, thereby improving the sealing performance of the vehicle, effectively reducing the risk of water leakage at the tailgate, and thus improving the quality of the vehicle.

[0015] (2) The main body of the rear door is the basic load-bearing structure. The reinforcing plate is connected to the top of the main body of the rear door. Its core function is to enhance the structural strength of the upper part of the rear door and provide a stable welding foundation for the longitudinal beam. The decorative plate covers the front side of the reinforcing plate and has both decorative and structural auxiliary functions.

[0016] (3) A recessed structure, such as a first groove, is specially set on the side of the longitudinal beam facing the front of the vehicle. This provides installation space for the first overlapping part. The first overlapping part of the decorative panel is embedded in the first groove of the longitudinal beam. This makes it easier for the first sealing surface of the decorative panel to be coplanar with the front side of the window frame, and can reduce the gap between the first sealing surface and the front side connection part.

[0017] (4) Along the left and right direction of the whole vehicle, from the inside side of the vehicle to the outside side, the upper end of the first overlapping part is inclined downward. When rainwater flows to the connection between the first sealing surface and the front side, the first overlapping part will guide the water flow to the outside side of the vehicle. This can effectively prevent water from flowing into the vehicle through the tiny seams of the connection part, which can better reduce the risk of rainwater entering the vehicle and further ensure the sealing performance of the rear door assembly.

[0018] Along the vertical direction of the vehicle, from top to bottom, the depth of the first groove gradually increases, and the thickness of the corresponding first overlapping part will gradually increase accordingly, so that the connection between the first sealing surface and the front side can be smoothly transitioned, which is conducive to ensuring the coplanarity of the first sealing surface and the front side.

[0019] (5) A second groove is specially provided on the side of the rear door body facing the front of the vehicle to provide installation space for the second overlapping part. The second overlapping part of the decorative panel is embedded in the second groove of the rear door body, which makes it convenient for the first sealing surface of the decorative panel to be coplanar with the second sealing surface of the rear door body, and can reduce the gap at the connection between the first sealing surface and the second sealing surface.

[0020] (6) Along the left and right direction of the whole vehicle, from the inside side to the outside side, the lower end of the second overlapping part is inclined downward. When rainwater flows to the connection of the first sealing surface and the second sealing surface, the lower part of the second overlapping part will guide the water flow to the outside side of the vehicle. This can effectively prevent water from flowing into the vehicle through the tiny seams of the connection part, which can better reduce the risk of rainwater entering the vehicle and further ensure the sealing performance of the tailgate assembly.

[0021] Along the vertical direction of the vehicle from bottom to top, the depth of the second groove gradually increases, and the thickness of the corresponding second overlapping part will gradually increase accordingly, so that the connection between the first sealing surface and the second sealing surface can be smoothly transitioned, which is conducive to ensuring the coplanarity of the first sealing surface and the second sealing surface.

[0022] (7) The decorative panel and the reinforcing plate are connected by snap-fit. No additional tools are required. During installation, simply align the snap-fit ​​of the decorative panel with the corresponding snap-fit ​​hole of the reinforcing plate and press firmly to complete the installation. During disassembly, simply apply a certain amount of external force to make the snap-fit ​​come out of the snap-fit ​​hole. The operation is simple and quick, which can greatly improve the assembly efficiency and reduce the installation cost.

[0023] (8) A sealing part is provided between the decorative panel and the reinforcing plate, which can better seal the gap between the decorative panel and the reinforcing plate. The sealing part extends along the vertical direction of the whole vehicle and extends to the rear side of the first overlapping part through the first extension part, which can better seal the gap between the decorative panel and the longitudinal beam connection part. It extends to the rear side of the second overlapping part through the second extension part, which can better seal the gap between the rear door body and the longitudinal beam connection part, which can ensure full height sealing from the upper part to the lower part of the rear door sealing surface, and prevent local air leakage and water leakage caused by the segmented design.

[0024] (9) The window frame is made of extruded aluminum, which can improve the structural strength of the window frame and improve the dimensional accuracy of the window frame. The production efficiency and material utilization rate of the window frame are high. The decorative panel is integrally formed by injection molding, which is convenient to cooperate with the longitudinal beam and the main body of the rear door, improves the coplanarity of the first sealing surface, the front side and the second sealing surface, thereby improving the sealing performance of the rear door assembly.

[0025] Another object of this application is to provide a vehicle having a tailgate assembly as described above.

[0026] The vehicle described in this application, by applying the above-mentioned tailgate assembly, the sealing surface formed by the first sealing surface, the front side of the window frame, and the second sealing surface, can better press against the door frame sealing strip on the vehicle body, thereby improving the sealing performance of the vehicle, reducing the risk of water leakage at the tailgate, and thus improving the quality of the vehicle.

[0037] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0038] An embodiment of the first aspect of this application provides a tailgate assembly that, by improving its structure, can better enhance the sealing performance of the tailgate.

[0039] In related technologies, the tailgate sealing surface is a profiled surface on the tailgate assembly, which is the sealing surface on the tailgate assembly used to press the door frame sealing strip on the vehicle body.

[0040] Existing tailgate assemblies generally include an inner tailgate panel and an outer tailgate panel. Both the inner and outer tailgate panels are made of metal materials such as steel, and both are formed by stamping.

[0041] The inner and outer panels of the tailgate are welded together, and both panels have stamped windows. Because the inner and outer panels are formed into a single structure using a stamping process, this type of tailgate assembly is generally referred to as a one-piece tailgate assembly.

[0042] For unibody tailgate assemblies, the use of steel for both the inner and outer tailgate panels results in a relatively heavy overall weight. With the increasing demand for weight reduction and cost reduction, split tailgate designs have emerged.

[0043] A split-type tailgate consists of a "∩"-shaped window frame and a roughly square tailgate sheet metal assembly. The tailgate window frame and the tailgate sheet metal assembly are connected together to form the window for installing glass. Because the tailgate window frame and the tailgate sheet metal assembly are manufactured separately, this type of tailgate is called a split-type tailgate.

[0044] In the structure of a split-type rear door, since both the rear door sheet metal components and the rear door window frame are made of metal, there are uneven overlapping surfaces at the joints between the rear door sheet metal components and the rear door window frame, making it impossible to set up a suitable structure to make the transition smooth.

[0045] In detail, in order to effectively reduce the weight of the rear door assembly, the inventors invented a rear door window frame made of extruded aluminum and formed by roll forming process.

[0046] Due to limitations in metal forming, protrusions and pits may occur at the connection points between the tailgate window frame and the tailgate sheet metal assembly, making it impossible to form a smooth sealing surface. When the tailgate assembly is closed, there is a problem of incomplete sealing between the sealing surface and the door frame sealing strip, affecting the sealing performance of the tailgate assembly.

[0047] In view of this, in order to overcome the shortcomings of the related technology, the rear door assembly of this embodiment combines... Figures 1 to 5As shown, in terms of overall design, the tailgate assembly mainly includes a tailgate sheet metal component 1 and a window frame 3 connected to the top of the tailgate sheet metal component 1.

[0048] It should be noted that this tailgate assembly is a split tailgate. Along the left-right direction of the vehicle, the structures on both sides of the tailgate assembly are symmetrical. To clearly understand the structure of the tailgate assembly, Figures 1 to 9 The structures shown are the connection structures of the left longitudinal beam 301 of the rear tailgate assembly and the sheet metal component 1 of the rear tailgate assembly.

[0049] Because the structure of the tailgate assembly is symmetrical on both sides, the following text will refer to... Figures 1 to 9 The rear tailgate assembly of this embodiment will be described using the left side structure of the rear tailgate assembly as an example.

[0050] The material and structure of the window frame 3 are as described above. The window frame 3 has longitudinal beams 301 located on both sides of itself, and a longitudinal beam 301 connecting the two longitudinal beams 301 together. The longitudinal beams 301 extend along the vertical direction of the whole vehicle, and the crossbeams extend along the horizontal direction of the whole vehicle.

[0051] The window frame 3 is welded to the tailgate sheet metal assembly 1 via two longitudinal beams 301, and each connection part is covered with a decorative panel 2 on the side facing the front of the vehicle. The decorative panel 2 is integrally molded using injection molding, and its material is plastic, which facilitates the molding of a structure that matches the longitudinal beams 301 and the tailgate sheet metal assembly 1 during processing.

[0052] For example Figure 3 As shown, each decorative panel 2 has a first sealing surface 205 facing the front of the vehicle. The first sealing surface 205, the front side 3012 of the window frame 3 and the second sealing surface 10112 on the tailgate sheet metal assembly 1 are coplanar and are all used to press against the door frame sealing strip 4 on the vehicle body.

[0053] It should be noted that the second sealing surface 10112 is specifically formed on the inner panel 1011 of the rear door described below. It should be understood that the sealing surface on the rear door sheet metal assembly 1 is referred to as the second sealing surface 10112 here, simply for the convenience of distinguishing it from the first sealing surface 205 on the decorative panel 2.

[0054] The tailgate assembly described in this embodiment covers the connection between the longitudinal beam 301 and the tailgate sheet metal assembly 1 with a decorative panel 2, so that the first sealing surface 205, the front side 3012 of the window frame 3, and the second sealing surface 10112 on the decorative panel 2 are coplanar. This can better press against the door frame sealing strip 4 on the vehicle body, thereby improving the vehicle's sealing performance, reducing the risk of water leakage at the tailgate, and thus improving the quality of the vehicle.

[0055] For ease of overall arrangement, in some exemplary embodiments, the tailgate sheet metal assembly 1 includes a tailgate body 101 and a reinforcing plate 102 connected above the tailgate body 101. Each longitudinal beam 301 is welded to the reinforcing plate 102, and a decorative panel 2 covers the front side of the reinforcing plate 102.

[0056] It should be noted that the main body 101 of the tailgate mainly includes an inner tailgate panel 1011 and an outer tailgate panel 1012. A cavity is formed between the inner tailgate panel 1011 and the outer tailgate panel 1012. The upper parts of the inner tailgate panel 1011 and the outer tailgate panel 1012 are connected by a tailgate reinforcing beam 1013. The tailgate reinforcing beam 1013 is positioned at the upper opening of the cavity, and an outer panel support plate 1014 is installed inside the cavity. The aforementioned reinforcing plate 102 is formed by a partial structure of the tailgate reinforcing beam 1013, which makes processing and assembly more convenient.

[0057] Since the inner rear door panel 1011 and the outer rear door panel 1012 are still made of steel, while the window frame 3 is made of extruded aluminum, they cannot be directly welded together due to structural limitations. Therefore, in a preferred embodiment, the rear door reinforcing beam 1013 has a first reinforcing plate 10131 attached to the outside of the inner rear door panel 1011, and a second reinforcing plate 10132 attached to the inside of the outer rear door panel 1012.

[0058] The rear door reinforcing beam 1013 is made of aluminum. It is riveted to the inner rear door panel 1011 via a first reinforcing plate 10131, and to the outer rear door panel 1012 via a second reinforcing plate 10132. Because the rear door reinforcing beam 1013 is made of aluminum, the longitudinal beam 301 of the window frame 3 can be welded to the rear door reinforcing beam 1013 to ensure the structural strength of the window frame 3 and the rear door sheet metal assembly 1, thereby ensuring the structural strength of the rear door assembly.

[0059] The main body 101 of the tailgate is the basic load-bearing structure and the main mounting carrier for other components, forming the main frame of the tailgate. The tailgate reinforcing beam 1013 is connected to the top of the tailgate main body 101. Its core function is to enhance the structural strength of the upper area of ​​the tailgate and provide a stable welding base for the longitudinal beam 301. The reinforcing plate 102 is used as part of the tailgate reinforcing beam 1013, which is convenient for processing and assembly. The decorative plate 2 covers the front of the reinforcing plate 102, serving both decorative and structural auxiliary functions.

[0060] Reference Figures 4 to 7As shown, in some exemplary embodiments, the longitudinal beam 301 has a first groove 3011 on the side facing forward of the vehicle, and the decorative panel 2 has a first overlapping portion 201 that overlaps the longitudinal beam 301. Preferably, the first overlapping portion 201 is embedded in the first groove 3011, and the side of the first overlapping portion 201 facing forward of the vehicle forms the upper part of the first sealing surface 205.

[0061] In detail, the size and shape of the first groove 3011 need to match the first overlapping part 201 of the decorative panel 2, so as to provide a suitable space for the subsequent embedding of the first overlapping part 201, and to better ensure the coplanarity of the first sealing surface 205 and the front side surface 3012.

[0062] In the above implementation, a recessed structure, namely a first groove 3011, is specially provided on the side of the longitudinal beam 301 facing the front of the vehicle. Specifically, the first groove 3011 is located at the lower part of the front side 3012 of the longitudinal beam 301, which can provide installation space for the first overlapping part 201.

[0063] The first overlapping part 201 of the decorative panel 2 is embedded in the first groove 3011 of the longitudinal beam 301. This makes it easier for the first sealing surface 205 on the decorative panel 2 to be coplanar with the front side 3012 of the window frame 3, and can reduce the gap between the first sealing surface 205 and the front side 3012.

[0064] To further improve sealing performance, in some exemplary embodiments, the upper end of the first overlapping portion 201 slopes downwards along the left-right direction of the vehicle from the interior side to the exterior side. For example... Figure 6 As shown, arrow a indicates the upper end of the first overlapping portion 201. Figure 6 In the middle, the left side of the first overlapping part 201 is the side closer to the outside of the vehicle, and the right side of the first overlapping part 201 is the side closer to the inside of the vehicle.

[0065] In this exemplary embodiment, the upper end of the first overlapping portion 201 is inclined downward along the left-right direction of the vehicle from the inside side to the outside side. When rainwater flows to the connection between the first sealing surface 205 and the front side 3012, the first overlapping portion 201 will guide the water flow to the outside side of the vehicle. This can effectively prevent water from flowing into the vehicle through the tiny seams of the connection, which can better reduce the risk of rainwater entering the vehicle and further ensure the sealing performance of the tailgate assembly.

[0066] Still refer to Figure 6 and Figure 7 As shown, in some exemplary embodiments, the depth of the first groove 3011 gradually increases from top to bottom along the vertical direction of the vehicle. For example... Figure 7In order to facilitate welding and connection with the aforementioned reinforcing plate 102, the bottom wall of the first groove 3011 is uneven and cannot be smoothly transitioned, thus making it difficult to guarantee the sealing performance of the rear door.

[0067] In this embodiment, the decorative panel 2 is made of plastic, and a first sealing surface 205 is formed on the side facing the front of the vehicle. The decorative panel 2 can be easily processed into a shape that matches the shape of the first groove 3011, so that the first sealing surface 205 and the front side surface 3012 of the longitudinal beam 301 are coplanar.

[0068] In detail, along the vertical direction of the vehicle, from top to bottom, the depth of the first groove 3011 gradually increases, and the thickness of the corresponding first overlapping part 201 will gradually increase accordingly, so that the connection between the first sealing surface 205 and the front side 3012 can be smoothly transitioned, which is conducive to ensuring the coplanarity of the first sealing surface 205 and the front side 3012.

[0069] To further ensure sealing performance, refer to Figures 4 to 6 and Figure 8 As shown, in some exemplary embodiments, the tailgate body 101 has a second groove 10111 on the side facing forward of the vehicle, and the trim panel 2 has a second overlapping portion 202 that overlaps the tailgate body 101. The second overlapping portion 202 is embedded in the second groove 10111, and the side of the second overlapping portion 202 facing forward of the vehicle forms the lower part of the first sealing surface 205.

[0070] In detail, the size and shape of the second groove 10111 need to match the second overlapping part 202 of the decorative panel 2, so as to provide a suitable space for the subsequent embedding of the second overlapping part 202, and to better ensure the coplanarity of the first sealing surface 205 and the second sealing surface 10112.

[0071] In the above embodiment, a second groove 10111 is specially provided on the side of the tailgate body 101 facing the front of the vehicle, which can provide installation space for the second overlapping part 202. The second overlapping part 202 of the decorative panel 2 is embedded in the second groove 10111 of the tailgate body 101. This makes it convenient for the first sealing surface 205 on the decorative panel 2 to be coplanar with the second sealing surface 10112 of the tailgate body 101, and can reduce the gap at the connection between the first sealing surface 205 and the second sealing surface 10112.

[0072] In the above implementation, a first overlapping portion 201 and a second overlapping portion 202 are provided simultaneously. The first overlapping portion 201 is used to overlap with the longitudinal beam 301 to realize the connection between the decorative panel 2 and the longitudinal beam 301, improve the assembly stability between the two, and can better ensure the smoothness of the connection between the first sealing surface 205 and the front side 3012 of the window frame 3.

[0073] The second overlapping part 202 is used to overlap with the rear door body 101, so that the decorative panel 2 is fixed on the rear door body 101 at the same time, which can ensure the overall assembly is firm, and at the same time can conveniently ensure the smoothness of the connection between the first sealing surface 205 and the second sealing surface 10112.

[0074] Still refer to Figure 6 and Figure 8 As shown, in some exemplary embodiments, the lower end of the second overlapping portion 202 slopes downward along the left-right direction of the vehicle from the inside side to the outside side. Figure 6 In the diagram, the position indicated by arrow b is the lower end of the second overlapping part 202.

[0075] In this implementation, the direction is from the inside of the vehicle to the outside along the left-right direction of the entire vehicle, that is... Figure 6 As shown, from right to left, the lower end of the second overlapping portion 202 slopes downward. When rainwater flows to the connection between the first sealing surface 205 and the second sealing surface 10112, the lower part of the second overlapping portion 202 will guide the water flow to the outside of the vehicle. This can effectively prevent water from flowing into the vehicle through the tiny seams at the connection, thus reducing the risk of rainwater entering the vehicle and further ensuring the sealing performance of the tailgate assembly.

[0076] Continue to refer to Figure 6 and Figure 8 As shown, in order to better ensure the sealing performance of the connection between the reinforcing plate 102 and the inner panel 1011 of the rear door, in some exemplary embodiments, the depth of the second groove 10111 gradually increases from bottom to top along the vertical direction of the vehicle.

[0077] In a preferred embodiment, a portion of the inner panel 1011 of the tailgate is recessed outwards to form a second groove 10111. The connection between the lower sidewall of the second groove 10111 and the second sealing surface 10112 is arc-shaped. Since the decorative panel 2 is made of plastic, the lower end of the second overlapping portion 202 can be processed into a matching arc shape through injection molding, thereby effectively reducing the surface difference between the first sealing surface 205 and the second sealing surface 10112.

[0078] In this embodiment, the depth of the second groove 10111 gradually increases from bottom to top along the vertical direction of the vehicle, and the thickness of the corresponding second overlapping part 202 will gradually increase accordingly, so that the connection part of the first sealing surface 205 and the second sealing surface 10112 can be smoothly transitioned, which is conducive to ensuring the coplanarity of the first sealing surface 205 and the second sealing surface 10112.

[0079] To improve ease of assembly and disassembly, in some exemplary embodiments, the decorative panel 2 and the reinforcing plate 102 are snap-fitted together. For example... Figure 9 The structure of the trim panel 2 is shown, with a buckle 203 and a limiting part 204 provided on the rearward side of the trim panel 2. (See reference...) Figure 2 and Figure 4 As shown, a card hole 1021 and a limiting groove 1022 are formed on the reinforcing plate 102.

[0080] There are two buckles 203, each corresponding to a corresponding hole 1021. Each buckle 203 is inserted into its corresponding hole 1021 to secure the decorative panel 2 to the reinforcing plate 102.
