Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a sealing structure. This application also relates to a vehicle using this sealing structure. Background Technology

[0002] On vehicles, the tailgate sealing strip is usually fitted with clips. The tailgate sealing strip is snapped onto the tailgate sheet metal, which can play a role in preventing dust and rain from the joint between the tailgate and the body.

[0003] In related technologies, the split-type rear door includes a window frame and a rear door body that forms the window with the window frame. Because the window frame and the rear door body need to be connected as one piece by welding, the shape of the base of the window frame is complex, and existing sealing strips cannot meet the sealing performance requirements of the base of the window frame. Utility Model Content

[0004] In view of this, this application aims to provide a sealing structure to facilitate increasing the gap between the tailgate and the countertop.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A sealing structure includes a first sealing portion for sealing the gap between the outer side of a window frame and a countersegment, and a second sealing portion disposed on the first sealing portion; The first sealing part includes a transverse sealing section that can be locked onto the window frame crossbeam of the window frame, and longitudinal sealing sections that are respectively connected to both ends of the transverse sealing section. Each of the longitudinal sealing sections can be locked onto the two window frame longitudinal beams of the window frame. Each of the longitudinal sealing sections has a second sealing part at the end away from the transverse sealing section. The upper part of each second sealing part can seal the gap between the window frame interior panel and the opposing component, and the lower part of each second sealing part can seal the gap between the rear door body and the opposing component.

[0006] Furthermore, a recessed portion is provided on the outer side of the lower part of the window frame longitudinal beam, and the recessed portion is recessed towards the inside of the vehicle along the left-right direction of the vehicle. The interior trim panel of the window frame has a trim flange embedded in the recess, and a groove for locking the longitudinal sealing section is formed between the trim flange and the longitudinal beam of the window frame.

[0007] Furthermore, the window frame longitudinal beam is provided with a first overlapping joint, and the edge of the trim panel flange is provided with a second overlapping joint, the first overlapping joint and the second overlapping joint being arranged continuously in the vertical direction of the vehicle; One side of the longitudinal sealing section is provided with an overlapping portion, the upper part of which overlaps with the first overlapping mating portion, and the lower part of which overlaps with the second overlapping mating portion.

[0008] Furthermore, the second sealing part includes a sealing part body, a lower lip provided on the outer side of the sealing part body, and a support part provided on the inner side of the sealing part body; The first side of the sealing part body is formed by conforming to the flange of the trim panel, and the second side of the sealing part body is formed by conforming to the edge of the rear door body; The lower lip is used to abut against the opposing component, and the support portion is used to abut against the outer side of the rear door body.

[0009] Furthermore, the support portion includes a first support plate extending inward from the inner side of the sealing portion body, and a second support plate respectively connected to the first support plate and the sealing portion body; The first support plate and the second support plate are arranged intersectingly and can both abut against the outer side of the rear door body.

[0010] Furthermore, the longitudinal sealing section has an upper lip located on its outer side, and the lower lip and the upper lip are arranged continuously in the vertical direction of the vehicle.

[0011] Furthermore, a first snap-fit ​​hole is provided on the outer side of the rear door reinforcing beam in the rear door body, and a second snap-fit ​​hole is provided on the outer side of the rear door body. The second sealing part is provided with two snap-fit ​​members, which are respectively snapped into the first snap-fit ​​hole and the second snap-fit ​​hole.

[0012] Furthermore, each of the aforementioned snap-fit ​​components includes an insert portion embedded within the second sealing portion, an extension portion extending from the insert portion in a direction away from the second sealing portion, and a snap-fit ​​ring surrounding the outer periphery of the extension portion.

[0013] Furthermore, the first sealing part and the second sealing part are molded into an integral structure through a rubber vulcanization process; and / or, The hardness of each of the second sealing portions is greater than that of the first sealing portion.

[0014] Compared with related technologies, this application has the following advantages: (1) The sealing structure described in this application is divided into a first sealing part and a second sealing part, and the first sealing part and the second sealing part are connected together for easy installation on the tailgate. The first sealing part can better seal the gap between the window frame and the counters. The second sealing part is located at the end of the longitudinal sealing section away from the transverse sealing section. When applied, it can be arranged at the connection between the window frame longitudinal beam and the tailgate body. The upper part of the second sealing part can seal the gap between the window frame interior panel and the counters, and the lower part of the second sealing part can seal the gap between the tailgate body and the counters, so that the sealing structure is continuous and complete, and can better seal the gap between the tailgate and the counters, thereby improving the sealing performance of the vehicle.

[0015] (2) A recess is provided on the outer side of the lower part of the window frame longitudinal beam, so that the trim flange of the window frame interior panel is embedded in the recess. When applied to the rear door, the window frame interior panel can be made of plastic material, which can make up for the problem of uneven surface at the welding connection position of the window frame longitudinal beam and the rear door body. Because a recess is provided on the outer side of the lower part of the window frame longitudinal beam, the lower part of the window frame longitudinal beam cannot form a complete groove for locking the first sealing structure due to material removal. The trim flange can cooperate with the window frame longitudinal beam to form a groove, thereby ensuring the stability and reliability of the first sealing structure.

[0016] (3) The first overlapping joint on the longitudinal beam of the window frame and the second overlapping joint on the trim panel flange are continuously arranged in the vertical direction of the vehicle, with the upper part of the overlapping joint overlapping the first overlapping joint and the lower part overlapping the second overlapping joint. This multi-part overlapping joint structure makes the connection between the components tighter and more stable. Compared with simple connection methods, this overlapping structure can effectively distribute and bear forces from different directions, reduce the relative displacement between components, and thus improve the stability of the window frame and the window frame interior panel structure.

[0017] (4) The lower lip of the second sealing part abuts against the opposing part, which can fit tightly against the opposing part to form an effective sealing barrier, preventing water, dust, air and other external elements from entering the vehicle through this part. The matching design of the sealing part body with the trim panel flange and the tailgate body can improve the appearance quality and greatly enhance the sealing performance. The support part is used to abut against the outer side of the tailgate body, so that the sealing part body is not easily deformed, thereby ensuring the sealing performance of the second sealing part stably.

[0018] (5) The first support plate extends inward from the inner side of the sealing part body. The second support plate is connected to the first support plate and the sealing part body respectively and the two are arranged to intersect. This cross structure can form a stable frame similar to a triangle, which has high stability and can effectively resist external forces from different directions, greatly enhance the structural strength of the support part itself, thereby effectively preventing the sealing part body from deforming, providing a solid support foundation for the second sealing part, and effectively ensuring the sealing effect of the second sealing part.

[0019] (6) The upper and lower lips are arranged continuously in the vertical direction of the vehicle, which can form a continuous and uninterrupted sealing barrier between the tailgate and the countertop. This continuous seal can effectively prevent water, dust, air and other external elements from entering the vehicle from different heights, avoiding leakage problems caused by discontinuous sealing, thereby greatly improving the sealing performance of the sealing structure.

[0020] (7) The two snap-fit ​​parts provided on the second sealing part correspond to the first snap-fit ​​hole on the outer side of the rear door reinforcing beam and the second snap-fit ​​hole on the outer side of the rear door body, respectively. During the assembly of the second sealing part, the operator only needs to accurately insert the snap-fit ​​parts into the corresponding snap-fit ​​holes to realize the connection between the second sealing part and the rear door reinforcing beam and the rear door body. This snap-fit ​​method is simple and quick to operate, does not require complicated tools and cumbersome operation steps, can greatly shorten the assembly time, improve production efficiency, and is easy to install and disassemble.

[0021] (8) The embedded part is embedded in the second sealing part. This design allows the snap-fit ​​part and the second sealing part to form a tight whole. The snap-fit ​​ring surrounding the outer periphery of the extension part can form a stable snap-fit ​​with the corresponding snap-fit ​​hole, such as the first snap-fit ​​hole of the rear door reinforcing beam and the second snap-fit ​​hole of the rear door body, during the snap-fit ​​process.

[0022] (9) The rubber vulcanization process forms a continuous and uninterrupted sealing structure between the first and second sealing parts. This structure can effectively prevent external water, dust, and air from entering the vehicle from different locations, improving the reliability and durability of the seal. The hardness of the second sealing part is greater than that of the first sealing part, and the first and second sealing parts are continuously arranged in the vertical direction of the vehicle. According to different sealing requirements, the first and second sealing parts can play their respective sealing roles, and can better ensure the sealing reliability of the tailgate.

[0023] Another object of this application is to provide a vehicle having a sealing structure on its rear door as described above.

[0024] The vehicle described in this application, by applying the above-mentioned sealing structure, ensures that the sealing structure at the connection between the window frame and the main body of the tailgate is continuous and complete, which can better seal the gap between the tailgate and the other parts, thereby improving the sealing performance of the vehicle.

[0034] 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.

[0035] An embodiment of the first aspect of this application provides a sealing structure that, by improving its own structure, can better seal the gap between the tailgate and the countertop, thereby improving the sealing performance of the tailgate.

[0036] In related technologies, on vehicles, the tailgate sealing strip is typically fitted with clips, and the tailgate sealing strip is snapped onto the tailgate sheet metal, serving to prevent dust and rain from entering the area where the tailgate and the vehicle body meet. The split tailgate in related technologies includes the tailgate sheet metal and the glass installed at the window position on the tailgate sheet metal.

[0037] The rear door sheet metal includes the window frame and the rear door body, which together form the aforementioned window. It should be noted that because the window frame and the rear door body need to be welded together, the base of the window frame has a complex shape, and existing sealing strips cannot meet the sealing performance requirements at the base of the window frame.

[0038] In view of this, in order to overcome the shortcomings of related technologies, the sealing structure of this embodiment combines... Figures 1 to 4As shown, the overall design includes a first sealing part 2 for sealing the gap between the outer side of the window frame 1 and the counter piece, and a second sealing part 3 provided on the first sealing part 2.

[0039] In detail, the first sealing part 2 includes a transverse sealing section that can be locked onto the window frame beam of the window frame 1, and longitudinal sealing sections 201 connected to both ends of the transverse sealing section. Each longitudinal sealing section 201 can be locked onto the two window frame beams 101 of the window frame 1.

[0040] Each longitudinal sealing section 201 has a second sealing part 3 at the end away from the transverse sealing section. The upper part of each second sealing part 3 can seal the gap between the window frame interior panel 4 and the counter piece, and the lower part of each second sealing part 3 can seal the gap between the rear door body 5 and the counter piece.

[0041] To better understand the sealing structure of this embodiment, please refer to the following: Figures 1 to 3 The structure of window frame 1 is described below. Window frame 1 includes a window frame horizontal beam and window frame vertical beams 101 placed on the left and right sides of the window frame horizontal beam. The window frame horizontal beam extends along the left and right direction of the vehicle, and the window frame vertical beams 101 extend along the up and down direction of the vehicle.

[0042] Window frame 1 is shaped like a "∩". During processing, it is formed by bending extruded aluminum. The cross-section of the horizontal beam of the window frame is the same as the cross-section of the vertical beam 101 of the window frame. Its structure can be referred to Figure 3 The structure shown is not shown in the figure.

[0043] Given that the cross-sectional shapes of the window frame horizontal beam and the window frame vertical beam 101 are the same, in this application, the cross-sections of the transverse sealing section and the longitudinal sealing section 201 are also the same. For details, please refer to... Figure 3 Therefore, the following description of this application will take the cross-section of the longitudinal sealing section 201 as an example, given the structure shown.

[0044] It should be noted that the counterpart parts mentioned in this application are the roof sheet metal of the vehicle for the window frame crossbeam and the side sheet metal of the vehicle for the window frame longitudinal beam 101.

[0045] The sealing structure described in this application is divided into a first sealing part 2 and a second sealing part 3, and the first sealing part 2 and the second sealing part 3 are connected together for easy installation on the rear door. The first sealing part 2 can better seal the gap between the window frame 1 and the counters.

[0046] The first sealing part 2 is formed by extrusion, and its cross-sectional shape remains unchanged along its extension direction. The second sealing part 3 is formed by injection molding.

[0047] The second sealing part 3 is located at the end of the longitudinal sealing section 201 away from the transverse sealing section. In application, it can be arranged at the connection between the window frame longitudinal beam 101 and the rear door body 5. The upper part of the second sealing part 3 can seal the gap between the window frame interior panel 4 and the counter piece, and the lower part of the second sealing part 3 can seal the gap between the rear door body 5 and the counter piece, so that the sealing structure is continuous and complete, and can better seal the gap between the rear door and the counter piece, thereby improving the sealing performance of the vehicle.

[0048] In one example, still refer to Figures 1 to 4 and combined Figure 12 As shown, the tailgate body 5 includes an inner tailgate panel 501 and an outer tailgate panel 502 that forms a cavity with the inner tailgate panel 501. A tailgate reinforcing beam 503 connects the inner tailgate panel 501 and the outer tailgate panel 502. The tailgate reinforcing beam 503 extends along the left-right direction of the vehicle and is located at the lower edge of the window. The tailgate reinforcing beam 503 is made of aluminum.

[0049] The rear door reinforcing beam 503 is connected to the rear door inner panel 501 by riveting, and the rear door reinforcing beam 503 is also connected to the rear door outer panel 502 by riveting. Then, the rear door body 5 is welded to the two longitudinal beams of the window frame 1 through the rear door reinforcing beam 503, thus forming a window.

[0050] For ease of overall layout, such as Figure 4 and Figure 12 As shown, in some preferred embodiments, a recess 1012 is provided on the outer side of the lower part of the window frame longitudinal beam 101, and the recess 1012 is recessed towards the interior side in the left-right direction of the vehicle. The window frame interior panel 4 has a trim flange 401 embedded in the recess 1012, and a groove 1013 for engaging the longitudinal sealing section 201 is formed between the trim flange 401 and the window frame longitudinal beam 101.

[0051] It should be noted that the window frame interior trim panel 4 is a trim panel located at the connection between the window frame longitudinal beam 101 and the rear door reinforcing beam 503. This window frame interior trim panel 4 covers the welded connection between the window frame longitudinal beam 101 and the rear door reinforcing beam 503, which can effectively shield the connection between the window frame longitudinal beam 101 and the rear door reinforcing beam 503, ensuring the appearance quality of the rear door, and at the same time ensuring the fitting accuracy between the rear door and the other parts.

[0052] In this embodiment, a recess 1012 is provided on the outer surface of the lower part of the window frame longitudinal beam 101, so that the trim flange 401 of the window frame interior panel 4 is embedded in the recess 1012. When applied to the rear door, the window frame interior panel 4 can be made of plastic material, which can compensate for the uneven surface at the welding connection between the window frame longitudinal beam 101 and the rear door body 5. Because the recess 1012 is provided on the outer surface of the lower part of the window frame longitudinal beam 101, some material is removed from the lower part of the window frame longitudinal beam 101, and the lower part of the window frame longitudinal beam 101 cannot form a complete groove 1013 for locking the first sealing structure. However, the trim flange 401 can cooperate with the window frame longitudinal beam 101 to form the groove 1013, thereby ensuring the stability and reliability of the first sealing structure.

[0053] In detail, to ensure the reliability of the first sealing part 2 being fixed to the window frame 1, it is still referred to Figure 3 As shown, in one example, the inner side of the longitudinal sealing section 201 is provided with two snap-fit ​​parts 2013, each snap-fit ​​part 2013 extending along the extension direction of the longitudinal sealing section 201. The window frame longitudinal beam 101 is provided with two slots 1013, both extending along the direction of the window frame longitudinal beam 101. The two snap-fit ​​parts 2013 are respectively snapped into the two slots 1013. The mating structure of the window frame horizontal beam and the transverse sealing section refers to the mating structure of the window frame longitudinal beam 101 and the longitudinal sealing section 201, and can still be referred to... Figure 3 As shown, it will not be described in detail here.

[0054] It should be noted that, referring to Figure 11 As shown, in the longitudinal direction of the vehicle, the window frame longitudinal beam 101 has two slots 1013. The rear slot 1013 is structurally complete along the entire extension direction of the window frame longitudinal beam 101. The front slot 1013 is structurally complete in the upper part of the window frame longitudinal beam 101. Due to the removal of some material in the lower part of the window frame longitudinal beam 101, it needs to cooperate with the window frame interior panel 4 to form a complete slot 1013. For details, please refer to... Figure 4 The structure shown.

[0055] To ensure the appearance quality of the sealed door, in some preferred embodiments, reference is still made to... Figure 2 , Figure 3 , Figure 4 , Figure 11 and Figure 12 As shown, the window frame longitudinal beam 101 is provided with a first overlapping mating part 1014, and the edge of the decorative panel flange 401 is provided with a second overlapping mating part 4011. One side of the longitudinal sealing section 201 is provided with an overlapping part 2011, the upper part of the overlapping part 2011 overlaps with the first overlapping mating part 1014, and the lower part of the overlapping part 2011 overlaps with the second overlapping mating part 4011.

[0056] It should be noted that, referring to Figure 4 , Figure 7 , Figure 8 and Figure 12 As shown, in one example, the overlapping portion 2011 and the upper lip 2012 of the front part are integrally formed. The overlapping portion 2011 extends from the upper lip 2012 of the front part towards the front of the vehicle, and the overlapping portion 2011 extends along the extending direction of the upper lip 2012. The overlapping portion 2011 and the first overlapping mating portion 1014 are interference-fitted, which not only ensures that the first sealing portion 2 is firmly fixed, but also that the first sealing portion 2 and the window frame interior panel 4 can fit tightly together. This can better ensure the fit quality between the longitudinal beam sealing section and the window frame interior panel 4, and better prevent water, dust, etc. from entering the slot 1013 from the mating part of the two. At the same time, from the outside, there is no visible gap between the first sealing portion 2 and the window frame interior panel 4, and the mating surface has a strong sense of refinement.

[0057] In one example, still refer to Figure 3 , Figure 4 , Figure 8 and Figure 12 As shown, the longitudinal sealing section 201 includes a main body 2015, a skeleton 2014 disposed within the main body 2015, an upper lip 2012 disposed on the outer side of the main body 2015, and a snap-fit ​​portion 2013 disposed on the inner side of the main body 2015. The main body 2015, the skeleton 2014, the upper lip 2012, and the snap-fit ​​portion 2013 all extend along the length direction of the longitudinal sealing section 201.

[0058] The skeleton 2014 is made of a hard material, such as metal, while the main body 2015, the upper lip 2012 and the snap-fit ​​part 2013 are all made of rubber.

[0059] To ensure a good seal, in one example, we still refer to... Figure 8 As shown, the upper part of the main body 2015 has a notch, and the upper connecting part 20151 is filled in the notch. The main body 2015 and the upper connecting part 20151 can be made of rubber with different hardness to ensure a better sealing effect.

[0060] In the above embodiment, the first overlapping part 1014 on the window frame longitudinal beam 101 and the second overlapping part 4011 on the trim panel flange 401 are continuously arranged in the vertical direction of the vehicle. The upper part of the overlapping part 2011 overlaps with the first overlapping part 1014, and the lower part of the overlapping part 2011 overlaps with the second overlapping part 4011. This multi-part overlapping structure makes the connection between the components tighter and more stable. Compared with simple connection methods, this overlapping structure can effectively distribute and bear forces from different directions, reduce the relative displacement between components, and thus improve the stability of the window frame 1 and the window frame interior panel 4 structure.

[0061] Reference Figures 1 to 4 and combined Figures 7 to 9 As shown, in some preferred embodiments, the second sealing part 3 includes a sealing part body 301, a lower lip 302 provided on the outer side of the sealing part body 301, and a support part 303 provided on the inner side of the sealing part body 301.

[0062] The first side 3011 of the sealing body 301 is shaped to conform to the trim panel flange 401, and the two are interference-fitted to ensure the continuity of the surface and a good appearance. The second side 3012 of the sealing body 301 is shaped to conform to the edge of the tailgate body 5, and the two are interference-fitted to ensure that the installed sealing body 301 can fit snugly against the edge of the tailgate inner panel 501, preventing the edge from warping. The lower lip 302 is used to abut against the opposing part, and the support part 303 is used to abut against the outer side of the tailgate body 5.

[0063] It should be noted that the edge of the inner rear door panel 501 is the edge portion of the inner rear door panel 501 facing the front of the vehicle, and the outer rear door panel 502 has an edge that folds onto the edge, hence it is called the edge of the inner rear door panel 501.

[0064] In the above implementation, the lower lip 302 on the second sealing part 3 abuts against the opposing part, ensuring a tight fit and forming an effective sealing barrier to prevent external water, dust, air, etc., from entering the vehicle interior. The matching design of the sealing part body 301 with the trim panel flange 401 and the tailgate body 5 significantly improves the appearance quality and greatly enhances the sealing performance. The support part 303 abuts against the outer side of the tailgate body 5, preventing the sealing part body 301 from collapsing or deforming, thus stably ensuring the sealing performance of the second sealing part 3.

[0065] To ensure the sealing effect of the second sealing part 3, in some preferred embodiments, the support part 303 includes a first support plate 3031 extending inward from the inner side of the sealing part body 301, and a second support plate 3032 connected to the first support plate 3031 and the sealing part body 301 respectively. The first support plate 3031 and the second support plate 3032 are arranged intersectingly. As in this application, there are two second support plates 3032. The first support plate 3031 and the two second support plates 3032 are arranged orthogonally, and both the first support plate 3031 and the two second support plates 3032 can abut against the outer side of the tailgate body 5 in the left-right direction of the vehicle.

[0066] In this embodiment, the first support plate 3031 extends inward from the inner side of the sealing part body 301, and the second support plate 3032 is connected to the first support plate 3031 and the sealing part body 301 respectively and the two are arranged to intersect. This cross structure can form a stable frame similar to a triangle, which has high stability and can effectively resist external forces from different directions, greatly enhancing the structural strength of the support part 303 itself, thereby effectively preventing deformation of the sealing part body, providing a solid support foundation for the second sealing part 3, and effectively ensuring the sealing effect of the second sealing part 3.

[0067] In some preferred embodiments, the longitudinal sealing section 201 has an upper lip 2012 located on its outer side, and the lower lip 302 and the upper lip 2012 are arranged continuously in the vertical direction of the vehicle.

[0068] It should be noted that, in one example, such as Figure 9 As shown, there are two lower lips 302, each extending along the vertical direction of the vehicle. The two lower lips 302 are spaced apart in the longitudinal direction of the vehicle, and the interference between the front lower lip 302 and the counterpart is smaller than the interference between the rear lower lip 302 and the counterpart.

[0069] In addition, two upper lips 2012 are provided on the outer side of the longitudinal beam sealing section, still referring to Figure 3 As shown, the two upper lips 2012 are arranged at a distance in the front-rear direction of the vehicle, and the interference between the front upper lip 2012 and the counter part is smaller than the interference between the rear upper lip 2012 and the counter part.

[0070] It should be noted that the number of upper lips 2012 is the same as the number of lower lips 302, and the upper lips 2012 and lower lips 302 correspond one-to-one. In the vertical direction of the vehicle, each upper lip 2012 and its corresponding lower lip 302 are arranged continuously.

[0071] In the above embodiment, the upper lip 2012 and the lower lip 302 are continuously arranged in the vertical direction of the vehicle, forming a continuous and uninterrupted sealing barrier between the tailgate and the countertop. This continuous seal can effectively prevent external water, dust, air, etc. from entering the vehicle from different heights, avoiding leakage problems caused by discontinuous sealing, thereby greatly improving the sealing performance of the sealing structure.

[0072] like Figure 5 and Figure 6 and combined Figure 9 As shown, in some preferred embodiments, a first snap-fit ​​hole 5031 is provided on the outer side of the rear door reinforcing beam 503, and a second snap-fit ​​hole 5011 is provided on the outer side of the rear door body 5. The second sealing part 3 is provided with two snap-fit ​​members 304, which are respectively snapped into the first snap-fit ​​hole 5031 and the second snap-fit ​​hole 5011.

[0073] In this embodiment, the second sealing part 3 is provided with two snap-fit ​​parts 304, both of which are made of relatively hard rubber material, such as standard parts. The two snap-fit ​​parts 304 correspond to the first snap-fit ​​hole 5031 on the outer side of the rear door reinforcing beam 503 and the second snap-fit ​​hole 5011 on the outer side of the rear door body 5, respectively. During the assembly of the second sealing part 3, the operator only needs to accurately insert the snap-fit ​​parts 304 into the corresponding snap-fit ​​holes to achieve a stable connection between the second sealing part 3 and the rear door reinforcing beam 503 and the rear door body 5. This snap-fit ​​method is simple and quick to operate, does not require complicated tools and cumbersome operating steps, can greatly shorten the assembly time, improve production efficiency, and is easy to install and disassemble.

[0074] Continue to refer to Figure 10 As shown, in some preferred embodiments, each snap-fit ​​member 304 includes an insert portion 3041 embedded in the second sealing portion 3, an extension portion 3042 extending from the insert portion 3041 in a direction away from the second sealing portion 3, and a snap-fit ​​ring 3043 surrounding the outer periphery of the extension portion 3042.

[0075] In one example, the insert 3041 is in the shape of a round rod, the extension 3042 is in the shape of a rod, and the snap ring 3043 is a plate-shaped ring. The insert 3041, the extension 3042 and the snap ring 3043 are arranged coaxially.

[0076] It should be understood that the embedded part 3041 is embedded in the second sealing part 3. This design allows the snap-fit ​​part 304 and the second sealing part 3 to form a tight whole. The snap-fit ​​ring 3043 surrounding the outer periphery of the extension part 3042 can form a stable snap-fit ​​with the corresponding snap-fit ​​holes, such as the first snap-fit ​​hole 5031 of the rear door reinforcing beam 503 and the second snap-fit ​​hole 5011 of the rear door body 5, during the snap-fit ​​process.

[0077] In one example, multiple snap-fit ​​rings 3043 are arranged at intervals along the extending direction of the extension 3042. Compared with a single snap-fit ​​ring 3043, multiple snap-fit ​​rings 3043 can form a multi-level snap-fit ​​structure, which greatly improves the stability and load-bearing capacity of the snap-fit. Even under large external impact, it can ensure a reliable connection between the snap-fit ​​member 304 and the snap-fit ​​hole, preventing loosening or detachment. It should be understood that a single snap-fit ​​ring 3043 is also feasible.

[0078] In some preferred embodiments, both the first sealing part 2 and the second sealing part 3 are made of rubber, and are molded into a single structure through a rubber vulcanization process, making the sealing structure easy to install and disassemble. The rubber vulcanization process forms a continuous, uninterrupted sealing structure between the first sealing part 2 and the second sealing part 3. This structure effectively prevents external water, dust, and air from entering the vehicle from different locations, improving the reliability and durability of the seal.

[0079] In some preferred embodiments, the hardness of each second sealing part 3 is greater than that of the first sealing part 2. Since the first sealing part 2 and the second sealing part 3 are arranged continuously in the vertical direction of the vehicle, the first sealing part 2 and the second sealing part 3 can perform their sealing functions according to different sealing requirements, and can better ensure the sealing reliability of the tailgate.

[0080] The rear door mentioned in this application specifically relates to a split rear door, which can solve the sealing problem between the rear door and the adjacent parts when the window frame 1 in the rear door is a roll-formed part. Moreover, the sealing structure is easy to install. By matching with the surrounding parts, it can not only be firmly installed, but also ensure sealing performance, while taking into account the exquisite appearance.

[0081] It is worth noting that, regarding the sealing structure of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 4 As shown, it may include, for example, a first sealing part 2 for sealing the gap between the outer side of the window frame 1 and the counter piece, and a second sealing part 3 provided on the first sealing part 2.

[0082] The first sealing part 2 includes a transverse sealing section that can be engaged on the window frame crossbeam of the window frame 1, and longitudinal sealing sections 201 connected to both ends of the transverse sealing section. Each longitudinal sealing section 201 can be engaged on the two window frame longitudinal beams 101 of the window frame 1. Each longitudinal sealing section 201 has a second sealing part 3 at the end away from the transverse sealing section. The upper part of each second sealing part 3 can seal the gap between the window frame interior panel 4 and the countertop, and the lower part of each second sealing part 3 can seal the gap between the rear door body 5 and the countertop.

[0083] In the preferred embodiment of the sealing structure above, the specific configuration and arrangement of the first sealing part 2, the second sealing part 3, etc. can still be referred to the description in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the first sealing part 2 and the second sealing part 3, etc., can also be referred to the description in the above exemplary embodiments.

[0084] An embodiment of the second aspect of this application provides a vehicle having the above-described sealing structure on its tailgate.

[0085] The vehicle in this embodiment, by applying the above-mentioned sealing structure, can effectively improve the sealing performance of the tailgate, ensure the reliability of the sealing strip installation, and guarantee the appearance quality of the tailgate, thereby improving the overall quality of the vehicle.

[0086] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
