Utility Model Content

[0005] In view of this, this application aims to provide a tailgate that improves the sealing performance of the tailgate.

[0006] To achieve the above objectives, the technical solution of this application is implemented as follows: A tailgate includes a tailgate sheet metal assembly, a tailgate window frame that forms a light-transmitting hole with the tailgate sheet metal assembly, and a sealing element disposed on the tailgate window frame. The seal has a first sealing portion located on the outer wall of the rear door / window frame, the first sealing portion being arranged around the rear door / window frame, and the first sealing portion being capable of sealing the gap between the rear door / window frame and the counter piece.

[0007] Furthermore, the tailgate sheet metal assembly includes an inner tailgate panel and an outer tailgate panel that are fastened together, and a tailgate window sill reinforcement plate connected between the inner tailgate panel and the outer tailgate panel. The longitudinal beams on both sides of the rear door and window frame are welded to the rear door and window sill reinforcement plate, and the rear side wall of the rear door and window frame is bonded to the rear door glass.

[0008] Furthermore, the rear door window sill reinforcement plate is riveted to the rear door inner panel and the rear door outer panel respectively; The areas where the rear door window sill reinforcement plate and the inner panel of the rear door are bonded together are bonded together with structural adhesive, and the areas where the rear door window sill reinforcement plate and the outer panel of the rear door are bonded together are also bonded together with structural adhesive.

[0009] Furthermore, the lower part of the longitudinal beam facing the rear of the vehicle is provided with an adhesive surface, and the longitudinal beam is bonded to the outer panel of the rear door through the adhesive surface; the rear door window sill reinforcement plate is made of aluminum; the inner panel of the rear door and the outer panel of the rear door are made of steel.

[0010] Furthermore, the connection points of the horizontal beam of the rear door and window frame and the longitudinal beams on both sides are provided with supporting corner joints; the sealing element has a second sealing portion surrounding the outer periphery of the supporting corner joint, the second sealing portion being able to seal the gap between the supporting corner joint and the connecting element.

[0011] Furthermore, a slot is provided on the outer wall of the rear door and window frame, and the sealing element has a snap-fit ​​part that is snapped into the slot; The seal has a first lip that abuts against the opposing member; and / or, the seal has a second lip that abuts against the rear door glass.

[0012] Furthermore, a protrusion is provided on the rear side wall of the rear door window frame. The protrusion protrudes from the rear door window frame toward the rear door glass and is arranged close to the inner side wall of the rear door window frame.

[0013] Furthermore, the rear door / window frame is made of extruded aluminum, and / or, The rear door and window frame is a solid structure.

[0014] The front sidewall of the rear door / window frame abuts against the door frame sealing strip, which can seal the gap between the rear door / window frame and the rear door frame.

[0015] Compared with related technologies, this application has the following advantages: (1) The tailgate described in this application provides a sealing element on the rear door window frame. Specifically, the sealing element has a first sealing portion on the outer wall of the rear door window frame and the first sealing portion is arranged around the rear door window frame. This structure is particularly suitable for sealing split tailgates. The first sealing portion can seal the gap between the outer periphery of the rear door window frame and the handle. Compared with the existing structure of sealing the front side of the rear door window frame and the rear door frame, it can better prevent rainwater from entering the gap between the rear door frame and the rear door, better improve the sealing quality of the rear door in the vehicle, reduce the noise entering the vehicle from the rear door, and thus improve the quality of the vehicle.

[0016] (2) The longitudinal beams on both sides of the rear door and window frame are connected to the rear door and window sill reinforcement plate by welding. The welding process can ensure the rigid fixation of the connection part, ensure that the rear door and window frame and the rear door and window sill reinforcement plate form an integral load-bearing structure, and improve the deformation resistance of the rear door. The rear door and window frame are bonded to the rear door glass, which can achieve surface contact sealing. This can not only ensure the stability of the rear door glass installation, but also enhance the sealing between the rear door glass and the rear door and window frame, and reduce the penetration path of rainwater, dust and noise.

[0017] (3) The rear door window sill reinforcement plate is the installation reference for the rear door window frame and glass. It is connected to the rear door inner panel and rear door outer panel by riveting process, and is also connected by structural adhesive. It has the characteristics of high connection strength and good stability, which can ensure that the rear door window frame is accurately positioned and not easily displaced during vehicle operation. It can provide a stable structural reference for the sealing of the seal and the fixing of the rear door glass, and prevent the sealing gap from becoming larger due to loose connection.

[0018] (4) The longitudinal beam serves as the supporting component on both sides of the rear door window frame. Its connection point with the rear door outer panel is located at the lower part of the rear side of the vehicle. This can specifically enhance the connection strength between the lower part of the door window frame and the outer panel. Especially during the opening and closing of the rear door, this area is the key path for force transmission. It can effectively disperse the impact force when opening and closing the door and reduce the deformation caused by excessive local force.

[0019] The tailgate window sill reinforcement plate is made of aluminum, which can significantly reduce the overall weight of the tailgate while ensuring a certain structural strength, in line with the development trend of vehicle lightweighting. The tailgate inner panel and tailgate outer panel, as the outer and inner skeleton of the tailgate, are made of steel, which can effectively withstand the impact force of opening and closing the door, the vibration load during vehicle driving, and the protection requirements during external collisions, ensuring the structural stability of the tailgate.

[0020] (5) A support joint is provided at the connection between the crossbeam and the longitudinal beam, so that the seal has a second sealing part around the outer periphery of the support joint, which can better adapt to the existing vehicle body and play a better sealing role. The support joint can provide sufficient support strength for the second sealing part, which is conducive to ensuring the sealing performance of the second sealing part.

[0021] (6) A slot is provided on the outer wall of the rear door and window frame, and the seal is snapped into the slot, so that the seal is easy to install on the rear door and window frame and is reliable and not easy to fall off. A first lip is provided on the seal, which can better seal the gap between the rear door and window frame and the seal. A second lip is provided, which can better seal the gap between the rear door and window frame and the rear door glass.

[0022] (7) The protrusion protrudes towards the side of the rear door glass. The part of the rear door window frame near the inner wall contacts the rear door glass through the protrusion, which can cover the bonding part of the rear door glass and the rear door window frame, improving the appearance quality of the rear door. At the same time, during the bonding process of the rear door glass and the rear door window frame, the protrusion can also better prevent the adhesive from overflowing, which also has the effect of improving the appearance quality.

[0023] (8) The rear door and window frame is made of extruded aluminum, which can effectively improve the bending and torsional strength of the window frame and resist the deformation caused by vehicle driving bumps and door opening and closing impacts. Aluminum easily forms a dense oxide film in the air, and can resist the corrosion of rain and humid environments without additional complicated anti-rust treatment. The rear door and window frame adopts a solid structure, which can maximize the rigidity, strength and deformation resistance of the rear door and window frame, achieving the same performance as steel window frames. Moreover, the low density of aluminum material makes the overall weight the same as steel.

[0024] (9) By pressing the front sidewall of the tailgate window frame against the door frame sealing strip, the gap between the tailgate window frame and the tailgate frame can be sealed. In conjunction with the aforementioned sealing components, two seals are formed at the tailgate. The combination of these two seals can significantly improve the sealing quality of the tailgate and reduce noise entering the vehicle from the tailgate, thereby improving the vehicle's quality. At the same time, this solution can eliminate the need for a tailgate trim panel and also reduce the number of work steps, resulting in a reduction in the weight and cost of the tailgate.

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

[0026] The vehicle described in this application, by applying the aforementioned tailgate, can significantly improve the sealing quality of the tailgate, enhance the driver's rear visibility, ensure the structural strength of the tailgate, and reduce the weight and cost of the tailgate.

[0036] 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.

[0037] An embodiment of the first aspect of this application provides a tailgate that improves the sealing performance of the tailgate by modifying its structure, while also ensuring the structural strength and rigidity of the tailgate and improving its light transmission performance.

[0038] In related technologies, the tailgate window frame is located at the upper part of the tailgate and provides mounting points for the tailgate glass, tailgate trim, etc., ensuring the strength and rigidity requirements of the tailgate. A conventional tailgate typically includes a stamped steel outer tailgate panel, a stamped steel inner tailgate panel, a stamped steel reinforcing plate, tailgate glass, and tailgate trim.

[0039] The rear door outer panel is welded to the rear door inner panel, and the rear door reinforcing plate is welded between the rear door outer panel and the rear door inner panel to form the rear door sheet metal assembly. The rear door glass is glued to the rear door outer panel with glass glue, and the rear door trim panel is snapped to the rear door inner panel with clips.

[0040] The door frame sealing strip at the rear door is usually installed on the rear door frame. When the rear door is closed, the front side of the inner panel of the rear door presses against the door frame sealing strip to achieve a seal. This sealing structure has a poor sealing effect.

[0041] In addition, relevant requirements stipulate that drivers should observe their rear view through the rearview mirror, and the rear door and window frame area should not obstruct the view.

[0042] However, in related technologies, the tailgate window frame and lower sheet metal are integrally stamped. Due to the stamping process and rigidity limitations, the tailgate sheet metal assembly is relatively wide in the lateral direction of the vehicle, which reduces the driver's rear visibility. Furthermore, the sharp edges of the stamped tailgate sheet metal assembly affect the perceived refinement, necessitating the addition of a tailgate trim panel. This further increases the lateral size of the tailgate window frame, easily obstructing the driver's rear view.

[0043] In view of this, in order to overcome the shortcomings of related technologies, the rear door of this embodiment combines... Figures 1 to 3 As shown, the overall design includes a rear door sheet metal assembly 1, a rear door window frame 2 that forms a light-transmitting hole d with the rear door sheet metal assembly 1, and a sealing element 3 provided on the rear door window frame 2.

[0044] Reference Figures 1 to 3 As shown in the preferred example, the seal 3 has a first sealing portion 30A located on the outer wall 201 of the rear door frame 2. The first sealing portion 30A is arranged around the rear door frame 2 and is capable of sealing the gap between the rear door frame 2 and the counter.

[0045] It should be noted that the rear door in this embodiment specifically relates to a split rear door, wherein the rear door window frame 2 is in the shape of "∩" and is connected to the rear door sheet metal assembly 1 at the lower part of the rear door to form the overall structure of the rear door.

[0046] To better understand the rear door of this embodiment, please refer to the following: Figure 6 and Figure 8 A brief description of the structure of the rear door window frame 2 is provided. The rear door window frame 2 is in the shape of a "∩". It includes a crossbeam 20a extending along the left and right direction of the vehicle, and two longitudinal beams 20b. The two longitudinal beams 20b extend downward from both ends of the crossbeam 20a, and each longitudinal beam 20b is arranged along the up and down direction of the vehicle.

[0047] It should also be noted that, in this application, the counterparts to the rear door window frame 2 include the vehicle side panel and the vehicle roof. The counterpart to the crossbeam 20a is the vehicle roof, while the counterpart to the longitudinal beam 20b is the vehicle side panel. Specifically, the counterpart to the left longitudinal beam 20b is the left side panel, and the counterpart to the right longitudinal beam 20b is the right side panel.

[0048] For ease of explanation, it should be understood that the sealing element 3 in this embodiment is located on the outer side wall 201 of the rear door and window frame 2. The outer side wall 201, inner side wall 202, front side wall 203 and rear side wall 204 of the rear door and window frame 2 will be described in detail below.

[0049] For the longitudinal beam 20b on the left side in the left-right direction of the vehicle, the left-facing sidewall of the longitudinal beam 20b is called the outer sidewall 201. For the longitudinal beam 20b on the right side in the left-right direction of the vehicle, the right-facing sidewall of the longitudinal beam 20b is called the outer sidewall 201. For the crossbeam 20a, the upward-facing sidewall along the vertical direction of the vehicle is called the outer sidewall 201. The sidewall opposite to each outer sidewall 201 is called the inner sidewall 202. Along the front-rear direction of the vehicle, the sidewall on the front side of the rear door window frame 2 is called the front sidewall 203, and the sidewall on the rear side of the rear door window frame 2 is called the rear sidewall 204.

[0050] In this embodiment, by providing a sealing element 3 on the rear door frame 2, specifically, by providing a first sealing part 30A on the outer wall 201 of the rear door frame 2 and arranging the sealing element 3 around the rear door frame 2, this structure is particularly suitable for sealing split rear doors.

[0051] The first sealing part 30A can seal the gap between the rear door window frame 2 and the countersleeve, which can improve the sealing quality of the rear door in the vehicle, reduce the noise entering the vehicle from the rear door, and thus improve the quality of the vehicle.

[0052] In some of these exemplary implementations, refer to Figures 1 to 6As shown, the tailgate sheet metal assembly 1 includes an inner tailgate panel 101 and an outer tailgate panel 102 that are fastened together, and a tailgate window sill reinforcement plate 103 connected between the inner tailgate panel 101 and the outer tailgate panel 102. The longitudinal beams 20b on both sides of the tailgate window frame 2 are welded to the tailgate window sill reinforcement plate 103, and the rear sidewall 204 of the tailgate window frame 2 is bonded to the tailgate glass 4.

[0053] Here, the inner panel 101 and the outer panel 102 of the rear door serve as the core skeleton, forming the basic outline of the rear door through fastening connection, and can bear the supporting role of the overall structure of the rear door. The rear door window sill reinforcement plate 103 is located between the inner panel 101 and the outer panel 102 of the rear door, which can better strengthen the structural strength of the window sill area, provide a stable foundation for the installation of the rear door window frame 2 and the rear door glass 4, and prevent deformation caused by long-term stress.

[0054] The longitudinal beams 20b on both sides of the rear door / window frame 2 are connected to the rear door / window sill reinforcing plate 103 by welding. Welding ensures the rigid fixation of the connection, guaranteeing that the rear door / window frame 2 and the rear door / window sill reinforcing plate 103 form an integral load-bearing structure, thus improving the rear door's resistance to deformation. The rear door / window frame 2 is bonded to the rear door glass 4, achieving surface contact sealing. This ensures the stability of the rear door glass 4 installation and enhances the sealing between the rear door glass 4 and the rear door / window frame 2, reducing the penetration paths of rainwater, dust, and noise.

[0055] In a preferred example, such as Figures 6 to 9 As shown, the weld e formed by the rear door and window sill reinforcement plate 103 and the rear door and window frame 2 can be machined to fit the shape of the rear door and window sill reinforcement plate 103 during actual processing, so that the two can be firmly welded together. Specifically, aluminum arc welding process is adopted.

[0056] The rear door window frame 2 and the rear door window sill reinforcement plate 103 are connected by aluminum arc welding on their YZ and XZ surfaces. It should be noted that the X direction is the front-to-back direction of the vehicle, the Y direction is the left-to-right direction of the vehicle, and the Z direction is the up-and-down direction of the vehicle.

[0057] In some exemplary embodiments, the rear door sill reinforcement plate 103 is riveted to the rear door inner panel 101 and the rear door outer panel 102, respectively. The bonding area between the rear door sill reinforcement plate 103 and the rear door inner panel 101, which mainly refers to the bonding area of ​​steel and aluminum, is bonded by structural adhesive, and the bonding area between the rear door sill reinforcement plate 103 and the rear door outer panel 102, which mainly refers to the bonding area of ​​steel and aluminum, is bonded by structural adhesive, forming the entire rear door sheet metal assembly 1.

[0058] It should be noted that the riveting mentioned in this embodiment specifically adopts SPR (Self-Piercing Riveting), which is a mechanical connection technology that does not require pre-drilling.

[0059] like Figure 6 and Figure 8 The structure shown has a rear door window sill reinforcement plate 103 extending along the left-right direction of the vehicle. It includes an inner reinforcement plate 1031, an outer reinforcement plate 1032, and a connecting plate 1033 connecting the inner reinforcement plate 1031 and the outer reinforcement plate 1032.

[0060] The inner reinforcing plate 1031 and the inner rear door panel 101 are riveted together, and are bonded together with structural adhesive in the area where they are attached. The outer reinforcing plate 1032 and the outer rear door panel 102 are riveted together, and are bonded together with structural adhesive in the area where they are attached.

[0061] In the above implementation, the rear door window sill reinforcement plate 103 serves as the installation reference for the rear door window frame 2 and the rear door glass 4. It is connected to the rear door inner panel 101 and the rear door outer panel 102 by riveting and structural adhesive bonding, which has the characteristics of high connection strength and good stability. It can ensure that the rear door window frame 2 is accurately positioned and not easily displaced during vehicle operation. It can provide a stable structural reference for the sealing of the seal 3 and the fixing of the rear door glass 4, preventing the sealing gap from increasing due to loose connection.

[0062] Structural adhesive is used because it combines bonding strength with a certain degree of flexibility. In terms of strength, it firmly bonds the rear door window sill reinforcement plate 103 to the rear door inner panel 101 and the rear door outer panel 102, enhancing the overall rigidity of the three and further strengthening the deformation resistance of the window sill area. In terms of sealing, the structural adhesive fills the tiny gaps in the bonding area, blocking the path of air and moisture penetration through the gaps between the panels, thus improving the overall sealing performance of the rear door.

[0063] To ensure the strength of the connection structure, such as Figure 8 and Figure 9 As shown, in some exemplary embodiments, the lower part of the longitudinal beam 20b facing the rear of the vehicle has an adhesive surface 206, and the longitudinal beam 20b is bonded to the outer panel 102 of the tailgate through the adhesive surface 206.

[0064] It should be noted that the bonding surface 206 is formed by a material removal molding process. It is bonded to the outer panel 102 of the tailgate, which can better ensure the bonding strength between the two. At the same time, it is beneficial to ensure that the outer surface of the outer panel 102 of the tailgate and the outer surface of the tailgate window frame 2 are coplanar, which can better ensure the appearance of the vehicle.

[0065] Here, the longitudinal beam 20b serves as a support component on both sides of the rear door window frame 2. Its connection point with the rear door outer panel 102 is located at the lower part of the rear side of the vehicle. This can specifically enhance the connection strength between the lower part of the window frame and the outer panel. Especially during the opening and closing of the rear door, this area is a key path for force transmission, which can effectively disperse the impact force when opening and closing the door and reduce deformation caused by excessive local force.

[0066] In terms of sealing performance, the rear and lower part of the vehicle are areas where rainwater and airflow can easily penetrate. Setting the adhesive surface 206 in this area can effectively seal the gaps in this area, thereby reducing the possibility of rainwater and dust entering the tailgate.

[0067] In some of the exemplary embodiments, the rear door window sill reinforcement plate 103 is made of aluminum, which can significantly reduce the overall weight of the rear door while ensuring a certain structural strength, in line with the development trend of vehicle lightweighting.

[0068] In some exemplary embodiments, the inner tailgate panel 101 and the outer tailgate panel 102 are made of steel, which may be formed, for example, by stamping. It should be noted that the inner tailgate panel 101 and the outer tailgate panel 102, as the outer and inner framework of the tailgate, are made of steel to effectively withstand the impact of opening and closing the door, the vibration load during vehicle movement, and the protection requirements during external collisions, ensuring the structural stability of the tailgate.

[0069] Depend on Figures 1 to 3 Combination Figure 6 As shown, in some exemplary embodiments, the connection points of the crossbeam 20a and the longitudinal beams 20b on both sides of the rear door / window frame 2 are provided with support corner joints 5. The seal 3 has a second sealing portion 30B surrounding the outer periphery of the support corner joint 5, which is capable of sealing the gap between the support corner joint 5 and the joint.

[0070] In a preferred embodiment, the support bracket 5 is made of a metal material, such as aluminum or steel, and is fixed to the connection between the crossbeam 20a and the longitudinal beam 20b by welding, screwing, or other means.

[0071] The support angle 5 is roughly triangular. When the seal 3 passes through the connection between the crossbeam 20a and the longitudinal beam 20b, it surrounds the outer periphery of the support angle 5 through the second sealing part 30B. The support angle 5 can support the seal 3 so that the seal 3 bends along a preset bending path.

[0072] Specifically, the second sealing part 30B extends along the left-right direction of the vehicle to seal the gap between the tailgate and the vehicle roof, and the second sealing part 30B extends along the up-down direction of the vehicle to seal the gap between the tailgate and the vehicle side panel.

[0073] It should be noted that the seal 3 adopts an integral molding structure, that is, each first sealing part 30A and each second sealing part 30B are connected together, which makes processing and assembly relatively convenient.

[0074] In this embodiment, a support angle 5 is provided at the connection between the crossbeam 20a and the longitudinal beam 20b, so that the seal 3 has a second sealing portion 30B surrounding the outer periphery of the support angle 5. This allows for better adaptation to the existing vehicle body and provides a better sealing effect. The support angle 5 provides sufficient support strength for the second sealing portion 30B, which helps to ensure the sealing performance of the second sealing portion 30B.

[0075] To improve the sealing performance of the seal 3, in some exemplary embodiments, a groove 2011 is provided on the outer wall 201 of the rear door frame 2, and the seal 3 has a snap-fit ​​part 301 that snaps into the groove 2011. The groove 2011 is provided on the outer wall 201 of the rear door frame 2, and the seal 3 snaps into the groove 2011, so that the seal 3 is easy to install on the rear door frame 2, and the installation is reliable and not easy to fall off.

[0076] In one example, there are two slots 2011, which are spaced apart along the front-rear direction of the vehicle, thus improving the reliability of the seal 3 on the rear door window frame 2. It should be understood that the number of slots 2011 can also be other, such as one, three, etc.

[0077] To improve the sealing performance of seal 3, such as Figure 3 and Figure 4 As shown, in one example, the seal 3 has a first lip 302 that abuts against the opposing member. Here, the first lip 302 on the seal 3 can better seal the gap between the rear door / window frame 2 and the opposing member.

[0078] It should be noted that the first lip 302 extends along the extension direction of the seal 3. Specifically, the seal 3 has a longitudinal beam sealing section located on the longitudinal beam 20b and a transverse beam sealing section located on the transverse beam 20a. The longitudinal beam sealing section extends along the extension direction of the longitudinal beam 20b, and the transverse beam sealing section extends along the extension direction of the transverse beam 20a.

[0079] The first lip 302 on the longitudinal beam sealing section extends along the extension direction of the longitudinal beam 20b, and the first lip 302 on the transverse beam sealing section extends along the extension direction of the transverse beam 20a. The first lip 302 on the longitudinal beam sealing section can abut against the corresponding side of the vehicle side panel, and the first lip 302 on the transverse beam sealing section can abut against the vehicle roof.

[0080] In one example, there are multiple first lips 302, and these multiple first lips 302 are arranged at intervals along the front-rear direction of the vehicle. For example... Figure 4 In the middle, the first lip edge 302 is two. It should be understood that the first lip edge 302 can also be one, three, four, etc.

[0081] Still refer to Figure 4 As shown, in one example, the seal 3 has a second lip 303 that abuts against the rear door glass 4. It should be noted that the second lip 303 also extends along the extension direction of the seal 3. Specifically, the second lip 303 on the longitudinal beam sealing section extends along the extension direction of the longitudinal beam 20b, and the second lip 303 on the transverse beam sealing section extends along the extension direction of the transverse beam 20a.

[0082] Here, by setting a second lip 303, it can press against the rear door glass 4, thereby better sealing the gap formed by the adhesive structural glue f between the rear door glass 4 and the rear door window frame 2. This can better prevent rainwater from entering the gap and affecting the bonding performance between the rear door glass 4 and the rear door window frame 2, and can also better improve the appearance quality of the rear door.

[0083] Continue to refer to Figure 4 As shown, in some exemplary embodiments, a protrusion 2041 is provided on the rear sidewall 204 of the rear door window frame 2. The protrusion 2041 protrudes from the rear door window frame 2 toward the rear door glass 4 and is arranged close to the inner sidewall 202 of the rear door window frame 2.

[0084] The protrusion 2041 extends along the extension direction of the seal 3. Specifically, the protrusion 2041 on the longitudinal beam sealing section extends along the extension direction of the longitudinal beam 20b, and the protrusion 2041 on the transverse beam sealing section extends along the extension direction of the transverse beam 20a.

[0085] In the above implementation, the protrusion 2041 protrudes towards the rear door glass 4, so that the part of the rear door window frame 2 near the inner wall 202 contacts the rear door glass 4 through the protrusion 2041. This can cover the bonding part of the rear door glass 4 and the rear door window frame 2, improving the appearance quality. At the same time, during the bonding process of the rear door glass 4 and the rear door window frame 2, the protrusion 2041 can also effectively prevent the adhesive from overflowing, which also has the effect of improving the appearance quality.

[0086] In some exemplary embodiments, the rear door and window frame 2 is made of extruded aluminum, which can effectively improve the bending and torsional strength of the window frame and resist the deformation caused by vehicle driving bumps and door opening and closing impacts. Aluminum easily forms a dense oxide film in the air, which can resist the corrosion of rain and humid environments without additional complicated anti-rust treatment.

[0087] In some exemplary embodiments, the rear door / window frame 2 is a solid structure. (Referring to...) Figure 4 As shown, the interior of the rear door and window frame 2 is a solid structure, which can maximize the rigidity, strength and deformation resistance of the rear door and window frame 2, so that the aluminum rear door and window frame 2 can achieve the same performance as the steel window frame. Moreover, the aluminum material has a low density and the overall weight is the same as that of the steel.

[0088] For example Figure 4 The diagram illustrates the structure of a rear door window frame 2. The front sidewall 203 of the rear door window frame 2 has a dimension of approximately 20mm in the lateral direction of the vehicle, such as 18mm, 19mm, 20mm, 21mm, or 22mm. The inner sidewall 202 of the rear door window frame 2 has a dimension of approximately 35mm in the longitudinal direction of the vehicle, such as 34mm, 35mm, 36mm, or 37mm. Compared to the existing rear door window frame with a dimension of approximately 100mm, this increases the lateral visibility of the vehicle by more than 60mm on one side.

[0089] In this embodiment, the rear door and window frame 2, as a key component of the window frame assembly structure, is designed with aluminum profiles as the material and a solid structure as the cross-section. This design can enhance the rigidity of the window frame assembly structure while ensuring lightweighting, thus meeting the rigidity requirements of the rear door assembly.

[0090] In some of these exemplary implementations, reference is still made to... Figure 3 and Figure 4 As shown, the front sidewall 203 of the rear door and window frame 2 abuts against the door frame sealing strip, which can seal the gap between the rear door and window frame 2 and the rear door frame.

[0091] Here, by pressing the front side wall 203 of the rear door window frame 2 against the door frame sealing strip, the gap between the rear door window frame 2 and the rear door frame can be sealed. This sealing structure, together with the sealing structure formed by the aforementioned sealing element 3, can form two seals at the rear door, which can significantly improve the sealing quality at the rear door, reduce the noise entering the vehicle from the rear door, and thus improve the quality of the vehicle.

[0092] It should also be noted that since the rear door window frame 2 uses a one-piece aluminum frame, both its front sidewall 203 and inner sidewall 202 are flat, resulting in better appearance quality. Furthermore, this design reduces the need for rear door trim panels and manufacturing processes, thus lowering the weight and cost of the rear door. In addition, eliminating the rear door trim panel reduces its obstruction of the light-transmitting opening d, thereby improving the driver's rear visibility.

[0093] It is worth noting that, regarding the rear door of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still [details omitted]. Figures 1 to 3 As shown, it may include, for example, a rear door sheet metal assembly 1, a rear door window frame 2 that forms a light-transmitting hole d with the rear door sheet metal assembly 1, and a sealing element 3 provided on the rear door window frame 2.

[0094] The seal 3 has a first sealing portion 30A located on the outer wall 201 of the rear door / window frame 2. The first sealing portion 30A is arranged around the rear door / window frame 2 and can seal the gap between the rear door / window frame 2 and the counters. The connection points of the crossbeam 20a and the longitudinal beams 20b on both sides of the rear door / window frame 2 are provided with support corner joints 5. The seal 3 has a second sealing portion 30B surrounding the outer periphery of the support corner joint 5 and can seal the gap between the support corner joint 5 and the counters.

[0095] The tailgate sheet metal assembly 1 includes a tailgate inner panel 101 and a tailgate outer panel 102 that are fastened together, and a tailgate window sill reinforcement plate 103 connected between the tailgate inner panel 101 and the tailgate outer panel 102; the longitudinal beams 20b on both sides of the tailgate window frame 2 are welded to the tailgate window sill reinforcement plate 103 respectively, and the rear side wall 204 of the tailgate window frame 2 is bonded to the tailgate glass 4.

[0096] The rear door sill reinforcement plate 103 is riveted to the rear door inner panel 101 and the rear door outer panel 102 respectively. The contact areas of the rear door sill reinforcement plate 103 and the rear door inner panel 101 are bonded with structural adhesive, and the contact areas of the rear door sill reinforcement plate 103 and the rear door outer panel 102 are also bonded with structural adhesive. The front side wall 203 of the rear door frame 2 abuts against the door frame sealing strip, which can seal the gap between the rear door frame 2 and the rear door frame.

[0097] This embodiment relates to a tailgate with a narrow-edge window frame structure that improves rear visibility and passability. The tailgate window frame 2 is formed from aluminum profiles through extrusion and bending processes. Specifically, the tailgate window frame 2 is a narrow, solid frame structure. The tailgate glass 4 is attached to the tailgate window frame 2. This structure eliminates the need for sharp edges formed by stamped sheet metal, eliminates the need for tailgate trim panels, reduces the number of parts, and further improves rear visibility and passability by reducing the cross-sectional area of ​​the tailgate window frame 1 in the left-right direction of the vehicle.

[0098] In the preferred embodiment of the rear door described above, the specific settings and arrangements of the rear door window frame 2, the rear door window sill reinforcement plate 103, etc., can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the rear door window frame 2, the rear door window sill reinforcement plate 103, etc., can also be referred to the descriptions in the above exemplary embodiments.

[0099] An embodiment of the second aspect of this application provides a vehicle having a tailgate as described in the above embodiment.

[0100] The vehicle described in this embodiment, by applying the aforementioned tailgate, can significantly improve the sealing quality of the tailgate, enhance the driver's rear visibility, ensure the structural strength of the tailgate, and reduce the weight and cost of the tailgate, thereby improving the overall quality of the vehicle.

[0101] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations.
