Description

Technical Field

[0001] This application belongs to the field of vehicle door sealing technology, and more specifically, relates to a vehicle door gap sealing component, a vehicle door assembly, and a vehicle. Background Technology

[0002] With the increasing popularity of automobiles, users are paying more and more attention to aspects such as car appearance, driving noise, and sealing. Door gap sealing strips are often used between car doors to enhance the sense of luxury in appearance. In addition, the sealing performance of door gap sealing strips can also reduce noise generated during driving.

[0003] In existing technologies, due to the complex structure of the corner of the car door, the door gap sealing strip cannot be installed directly, or the door gap sealing strip is prone to loosening and falling off after installation, resulting in poor actual sealing effect and insecure fixation. This not only affects the appearance of the car door but also generates a lot of noise during the process. Utility Model Content

[0004] The purpose of this application is to provide a door gap sealing component, a door assembly, and a vehicle, which aims to solve the technical problems of poor installation stability of existing door gap sealing strips, affecting door gap sealing and aesthetics, and easily generating noise.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a door gap sealing assembly is provided, comprising: A sealing strip abuts against the front end face of the rear door assembly; the outer side of the sealing strip has a forward-extending first bend that abuts against the interior of the front door assembly; the inner side of the sealing strip has a rearward-extending second bend that abuts against the rear door assembly; and The cover plate abuts against the sealing strip and presses the sealing strip firmly against the rear door assembly; The cover plate extends outward to near the first bend, and the inner side of the cover plate has a first limiting part that bends backward, which presses against the second bend.

[0006] Compared with the prior art, the solution shown in this application embodiment can achieve sealing at the joint between the front door assembly and the rear door assembly by setting a sealing strip between them, thereby effectively reducing noise during driving. Specifically, the first bend extends forward to achieve sealing at the outer joint between the front door assembly and the rear door assembly, maintaining the external sealing effect and aesthetics. The second bend extends backward and abuts against the rear door assembly to achieve sealing at the rear door assembly and to make the connection between the sealing strip and the rear door assembly smooth, ensuring the aesthetics of the connection between the sealing strip and the interior of the rear door assembly. The cover plate abuts against and presses against the sealing strip to press the sealing strip onto the rear door assembly, thereby fixing the sealing strip. Furthermore, the outer side of the cover plate extends to near the first bend, which can effectively ensure the pressing strength of the first bend on the sealing strip. The second limiting part on the inner side of the cover plate presses against the second bend, which can ensure the pressing strength at the second bend, thereby achieving the pressing of the sealing strip from the outside to the inside and ensuring the stability of the connection between the sealing strip and the rear door assembly.

[0007] Therefore, the door seam sealing assembly provided in this application can seal the joint between the front door assembly and the rear door assembly, reduce noise during driving, and ensure the aesthetics of the joint. In addition, the sealing strip has good installation stability, high connection strength, and is not easy to fall off or loosen.

[0008] In conjunction with the first aspect, in one possible implementation, the second bent portion is provided with an outwardly recessed limiting groove, the limiting groove extending in a vertical direction; the first limiting portion extends into the limiting groove and abuts against the inner wall of the limiting groove.

[0009] By setting a limiting groove, the first limiting part can be inserted into the corresponding limiting groove to press the sealing strip; and the first limiting part abuts against the inner wall of the limiting groove to ensure the pressing strength of the first limiting part and improve the connection stability between the sealing strip and the rear door assembly.

[0010] In some embodiments, after the first limiting portion extends into the limiting groove, the inner side of the first limiting portion is flush with the inner side of the second bending portion.

[0011] By making the inner side of the first limiting part flush with the inner side of the second bending part, the consistency of the sealing strip and the cover plate on the inner side can be maintained, the flatness of the connection between the cover plate and the sealing strip can be improved, and the aesthetics of the connection between the cover plate and the sealing strip can be improved.

[0012] For example, the bottom of the cover plate is bent backwards to have a second limiting portion, and the second limiting portion abuts against the bottom of the sealing strip.

[0013] By setting a second limiting part to limit the bottom of the sealing strip, and by abutting the bottom of the sealing strip, on the one hand, the aesthetics of the connection between the bottom of the sealing strip and the cover plate can be ensured; on the other hand, the second limiting part of the cover plate can support the bottom of the sealing strip and prevent the sealing strip from sagging, falling or even coming off.

[0014] In conjunction with the first aspect, in one possible implementation, a snap-fit ​​structure is provided between the cover plate and the front end face of the rear door assembly, which passes through the sealing strip, and the cover plate presses the sealing strip tightly through the snap-fit ​​structure.

[0015] In this application, the cover plate is provided with a snap-fit ​​structure that passes through the sealing strip and snaps into the rear door assembly. This is used to press the sealing strip tightly against the front end face of the rear door assembly, thereby ensuring the connection stability between the cover plate and the sealing strip.

[0016] In some embodiments, the snap-fit ​​structure includes: Multiple sets of limiting clips are spaced vertically on the side of the cover plate facing the sealing strip; the limiting clips are provided with a first groove and a second groove spaced along the front-back direction; Multiple sets of first clearance holes are spaced vertically on the sealing strip and correspond one-to-one with multiple sets of limit clips; and Multiple sets of snap-fit ​​holes are spaced vertically on the front end face of the rear door assembly, and each set of the limiting clips corresponds to one of them. When the end of the limiting card away from the cover plate is engaged in the rear door assembly, the wall of the first clearance hole is limited within the first groove, and the wall of the engaging hole is limited within the second groove.

[0017] By setting multiple sets of limit clips, the cover plate and the front end face of the rear door assembly can be engaged. Furthermore, when the limit clip is engaged in the rear door assembly, the limit clip has a first groove that engages with the corresponding first clearance hole, and a second groove that engages with the corresponding engagement hole, thereby achieving a two-stage clamping of the limit clip. This improves the connection stability between the cover plate and the front end face of the rear door assembly, enhances the sealing effect of the sealing strip, and reduces noise generated during driving.

[0018] For example, the limiting card includes two card plates arranged opposite each other, each card plate having a protrusion structure protruding away from each other; wherein, the first groove and the second groove are provided on the card plates and are positioned between the cover plate and the protrusion structure; the protrusion structure passes through the first clearance hole and the snap-fit ​​hole in sequence, and is limited to the snap-fit ​​hole on the rear side away from the sealing strip.

[0019] By setting two sets of clamping plates opposite each other, a set of protruding structures can be set on each set of clamping plates to form two opposite clamping points, thereby improving the clamping strength of the limit clamp. By setting the protruding structures on the clamping plates, the protruding structures can be limited to the back side of the clamping hole away from the sealing strip, thereby realizing the limiting connection between the limit clamp and the rear door assembly, improving the connection strength between the cover plate and the rear door assembly, and effectively ensuring the sealing performance and connection stability of the sealing strip.

[0020] Secondly, this application also provides a door assembly, including: Front door components; A rear door assembly, spaced apart at the rear side of the front door assembly; and The aforementioned door gap sealing assembly is positioned between the front door assembly and the rear door assembly.

[0021] The door assembly provided in this application embodiment includes the aforementioned door gap sealing component, and therefore has all the beneficial effects of the aforementioned door gap sealing component. It can improve the connection strength of the sealing component at the joint between the front door component and the rear door component, ensure the sealing performance of the sealing strip, and reduce noise during driving.

[0022] In conjunction with the second aspect, in one possible implementation, the rear door assembly includes a rear door sheet metal, a rear exterior trim panel disposed on the outside of the rear door sheet metal, and a rear interior trim panel disposed on the inside of the rear door sheet metal. The rear exterior trim panel has a first flange that bends inward and extends to the rear door sheet metal, and the sealing strip abuts against the first flange; a second bend is clamped between the rear door sheet metal and the rear interior trim panel.

[0023] The first flange faces the sealing strip to form the front end of the rear door assembly. The first flange is used to achieve the snap-fit ​​and limiting between the rear door assembly and the cover plate through the above-mentioned snap-fit ​​structure. The second bent part extends between the rear door sheet metal and the rear interior panel, and clamps the second bent part of the sealing strip between the rear door sheet metal and the rear interior panel. On the one hand, it can realize the fixation and positioning of the second bent part, avoid the sealing strip from loosening, and further enhance the stability of the sealing strip connection. On the other hand, it can realize the transition connection between the rear door assembly and the inner side of the sealing strip, and hide the end of the second bent part of the sealing strip between the rear door sheet metal and the rear interior panel, which can further improve the aesthetics of the connection.

[0024] Thirdly, embodiments of this application also provide a vehicle including the aforementioned door assembly.

[0025] The vehicle provided in this application embodiment, having the aforementioned door assembly, possesses all the beneficial effects of the aforementioned door assembly. It can improve the sealing performance of the joint between the front door assembly and the rear door assembly, reduce noise during driving, and ensure the aesthetics of the joint. Furthermore, the sealing strip at the joint has good installation stability and high connection strength. Attached Figure Description

[0029] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0030] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] It should be noted that the directions or positional relationships indicated by "front", "rear", "inner", "outer", "up", and "down" in this embodiment are based on the vehicle's own orientation. The front of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", the bottom of the vehicle represents "down", the "inner" side refers to the side facing the driver's cab or the interior of the passenger compartment, and the "outer" side refers to the side facing the exterior of the driver's cab or the exterior of the passenger compartment.

[0033] In addition, the front-rear direction of the vehicle body as defined in the embodiments of this application refers to the front-rear direction of the vehicle's forward direction during driving; the left-right direction of the vehicle body as defined refers to the left-right direction of the vehicle's forward direction during driving; and the up-down direction of the vehicle body as defined refers to the up-down direction of the vehicle's forward direction during driving.

[0034] It is important to understand that there is a seam between the front door assembly 1 and the rear door assembly 2, and the size of the gap at the seam directly affects the aesthetics and sealing of the door assembly structure. The connection strength and stability of the sealing strip 3 directly affect the sealing performance of the sealing strip 3. If the connection strength of the sealing strip 3 is insufficient, it may fall off or loosen during vehicle operation, which may cause noise at the seam and affect the user's riding experience.

[0035] In traditional technology, the sealing strip 3 is mainly fixed by multi-point snap-fit, with multiple corner inserts and limiting structures on the corner inserts to enhance the connection strength between the sealing strip 3 and the rear door assembly 2. On the one hand, this increases the manufacturing cost and difficulty of the sealing strip 3. On the other hand, the connection is only good at the corresponding points of the limiting structure, but there are still problems of detachment and lifting at the edges, so its actual sealing effect is poor.

[0036] Please refer to the following: Figures 1 to 8The following describes the door gap sealing assembly, door assembly, and vehicle provided in this application. The door gap sealing assembly includes a sealing strip 3 and a cover plate 4; the sealing strip 3 is disposed on the front end face of the rear door assembly 2; the outer side of the sealing strip 3 has a forward-extending first bend 31, which is used to abut against the inside of the front door assembly 1; the inner side of the sealing strip 3 has a rearward-extending second bend 32, which abuts against the rear door assembly 2; the cover plate 4 abuts against the sealing strip 3 and presses the sealing strip 3 against the rear door assembly 2; wherein, the outer side of the cover plate 4 extends outward to near the first bend 31, and the inner side of the cover plate 4 has a rearward-bent first limiting part 41, which presses against the second bend 32.

[0037] It is important to understand that the first bend 31 bends forward, and the structure formed after the bend is not a planar structure, but rather has an arc curving inwards to abut against the front door assembly 1 and extend inwards to a certain extent, so as to ensure the sealing strength of the outer side of the sealing strip 3. The shape of the bending surface of the second bend 32 is also not a straight planar structure, but rather matches the shape of the abutting surface of the rear door assembly 2.

[0038] A connecting body is provided between the first bending part 31 and the second bending part 32. The first bending part 31, the second bending part 32 and the connecting body form an approximately Z-shaped cross section, which is used to achieve sealing at the joint between the front door assembly 1 and the rear door assembly 2.

[0039] Furthermore, in this application, the cover plate 4 is abutted on the connecting body of the sealing strip 3. The first limiting part 41 of the cover plate 4 abuts against the second bending part 32 of the sealing strip 3. When the cover plate 4 is fastened to the front end face of the rear door assembly 2 through the snap-fit ​​structure, the cover plate 4 can press the sealing strip 3 onto the rear door assembly 2. Because the cover plate 4 has the aforementioned first limiting part 41 and extends outward to near the first bending part 31, it can achieve full pressing of the sealing strip 3, ensuring the connection strength between the sealing strip 3 and the rear door assembly 2.

[0040] It should be understood that a bending angle is formed between the first limiting part 41 of the cover plate 4 and the main body part of the cover plate 4 covering the sealing strip 3. This bending angle can effectively protect the bending point between the second bending part 32 of the sealing strip 3 and the connecting body, reduce the risk of damage to the bending point of the sealing strip 3 during long-term use, and extend the service life of the second sealing strip 3.

[0041] Optionally, the rearward extension length of the first limiting part 41 can be selectively set according to actual needs; optionally, the first limiting part 41 presses against part of the structure of the second bending part 32; optionally, the first limiting part 41 is completely pressed against the entire second bending part 32.

[0042] Optionally, the sealing strip 3 can be made of EPDM or TPV. EPDM is a copolymer of ethylene, propylene, and a small amount of non-conjugated diene, and is a type of ethylene propylene rubber. TPV is a thermoplastic vulcanized rubber, also belonging to the category of thermoplastic elastomers, generally referring to a blend system of PP+EPDM, which is a combination of the properties of plastic and rubber. The cover plate 4 can be made of PC and / or ABS. PC is short for polycarbonate, a colorless and transparent amorphous thermoplastic material. ABS is a graft copolymer of acrylonitrile, butadiene, and styrene monomers. It should be noted that the structure and processing technology of EPDM and TPV materials, as well as PC and ABS materials, are existing technologies and will not be described in detail here.

[0043] It should be understood that since the sealing strip 3 and the cover plate 4 are connected to the rear door assembly 2 via a snap-fit ​​structure, when the rear door is opened, the sealing strip 3 and the cover plate 4 also move synchronously with the rear door assembly 2. The front door assembly 1 abuts against the first bend 31 on the outer side of the sealing strip 3. When the front door is opened, the front door assembly 1 separates from the first bend 31; when the front door is closed, the front door abuts against the first bend 31 of the sealing strip 3.

[0044] Compared with the prior art, the door seam sealing assembly provided in this application can achieve sealing at the joint between the front door assembly 1 and the rear door assembly 2 by setting a sealing strip 3 between the front door assembly 1 and the rear door assembly 2, so as to effectively reduce noise during driving. Specifically, the first bend 31 extends forward to achieve sealing at the outer joint between the front door assembly 1 and the rear door assembly 2, maintaining the external sealing effect and aesthetics; the second bend 32 extends backward and abuts against the rear door assembly 2 to achieve sealing at the rear door assembly 2, and to make the connection between the sealing strip 3 and the rear door assembly 2 smooth, ensuring the aesthetics of the connection between the sealing strip 3 and the interior of the rear door assembly 2. The cover plate 4 abuts against and presses against the sealing strip 3 to press the sealing strip 3 onto the rear door assembly 2, thereby fixing the sealing strip 3. Furthermore, the outer side of the cover plate 4 extends to near the first bend 31, which can effectively ensure the pressing strength of the first bend 31 on the sealing strip 3. The second limiting part 42 on the inner side of the cover plate 4 presses against the second bend 32, which can ensure the pressing strength at the second bend 32, thereby achieving the pressing of the sealing strip 3 from the outside to the inside, ensuring the stability of the connection between the sealing strip 3 and the rear door assembly 2.

[0045] Therefore, the door seam sealing assembly provided in this application can seal the joint between the front door assembly 1 and the rear door assembly 2, reduce noise during driving, and ensure the aesthetics of the joint. In addition, the sealing strip 3 has good installation stability, high connection strength, and is not easy to fall off or loosen.

[0046] Please see Figure 2 and Figure 3In some possible embodiments, the second bent portion 32 is provided with an outwardly recessed limiting groove 321, which extends vertically; the first limiting portion 41 extends into the limiting groove 321 and abuts against the inner wall of the limiting groove 321.

[0047] By setting the limiting groove 321, the first limiting part 41 can be inserted into the corresponding limiting groove 321 to press the sealing strip 3; and the first limiting part 41 abuts against the inner groove wall of the limiting groove 321, which can ensure the pressing strength of the first limiting part 41, improve the connection stability between the sealing strip 3 and the rear door assembly 2, and make the sealing strip 3 less prone to loosening, thereby better ensuring the sealing effect and the stability of the overall structure.

[0048] Specifically, the limiting groove 321 extends to the inner side and the front side of the sealing strip 3. At this time, the limiting groove 321 has two inner groove walls connected in sequence, and the two inner groove walls form an L-shaped structure in cross section. The first limiting part 41 abuts against the two inner groove walls to press the sealing strip 3.

[0049] Optionally, the limiting groove 321 provided on the second bending part 32 only penetrates the inner side of the sealing strip 3. In this case, the limiting groove 321 has three inner groove walls connected in sequence, and the three inner groove walls form a U-shaped structure in cross section. The first limiting part 41 is provided with a protrusion that matches the U-shaped structure. The protrusion extends into the limiting groove 321 and abuts against the three inner groove walls to press the sealing strip 3.

[0050] Please see Figure 2 and Figure 3 In some embodiments, after the first limiting part 41 extends into the limiting groove 321, the inner side of the first limiting part 41 is flush with the inner side of the second bending part 32.

[0051] Specifically, in this application, the inner side refers to the side of the first limiting part 41 that is away from the sealing strip 3, which is also the side facing the inside of the carriage. The inner side of the second bending part 32 also refers to the side facing the inside of the carriage.

[0052] It should be understood that after the first limiting part 41 extends into the limiting groove 321, by making the inner side of the first limiting part 41 flush with the inner side of the second bending part 32, the consistency of the sealing strip 3 and the cover plate 4 on the inner side can be maintained, the flatness of the connection between the cover plate 4 and the sealing strip 3 can be improved, and the aesthetics of the connection between the cover plate 4 and the sealing strip 3 can be improved.

[0053] It should be noted that the second bending portion 32 is provided with a limiting groove 321. Therefore, the first limiting portion 41 can be placed in the limiting groove 321. When the depth of the limiting groove 321 in the vehicle's inner and outer directions is the same as the thickness of the first limiting portion 41 of the cover plate 4, the first limiting portion 41 is completely placed in the limiting groove 321 and does not protrude out of the limiting groove 321. At this time, the inner side of the first limiting portion 41 can be kept flush with the inner side of the second bending portion 32.

[0054] It should be understood that when the rearward extension length of the first limiting part 41 is less than the rearward extension length of the second bending part 32, preferably, the limiting groove 321 is provided on the second bending part 32 to limit the first limiting part 41; at this time, the second bending part 32 is clamped between the rear door sheet metal 21 and the rear interior panel 22 of the rear door assembly 2, and the first limiting part 41 is placed outside the rear interior panel 22.

[0055] Optionally, when the rearward extension length of the first limiting part 41 is equal to the rearward extension length of the second bending part 32, the first limiting part 41 is simultaneously clamped between the rear door sheet metal 21 and the rear interior panel 22 of the rear door assembly 2 along with the second bending part 32; at this time, there is no need to set the above-mentioned limiting groove 321, and the first limiting part 41 of the cover plate 4 and the rear interior panel 22 together form the internal decorative surface at the joint.

[0056] Please see Figure 5 For example, the bottom of the cover plate 4 is bent backward with a second limiting part 42, and the second limiting part 42 abuts against the bottom of the sealing strip 3.

[0057] By setting a second limiting part 42 to limit the bottom of the sealing strip 3, and by abutting the bottom of the sealing strip 3, on the one hand, the aesthetics of the connection between the bottom of the sealing strip 3 and the cover plate 4 can be ensured; on the other hand, the second limiting part 42 of the cover plate 4 can support the bottom of the sealing strip 3 and prevent the sealing strip 3 from sagging, falling or even coming off.

[0058] It should be understood that the second limiting part 42 further limits and fixes the sealing strip 3 from the bottom, which enhances the stability of the sealing strip 3 installation in all aspects, ensures a good sealing effect, and also helps to improve the stability and reliability of the overall structure.

[0059] It should be noted that the top surface of the second limiting part 42 is connected to the bottom of the main body of the cover plate 4 and the bottom of the first limiting part 41, so that the cover plate 4 extends from the connecting body of the sealing strip 3 to the bottom of the second bending part 32, thereby enhancing the support force of the bottom of the cover plate 4.

[0060] Please see Figure 5 In some possible embodiments, a snap-fit ​​structure is provided between the cover plate 4 and the front end face of the rear door assembly 2, which passes through the sealing strip 3; the cover plate 4 presses the sealing strip 3 tightly through the snap-fit ​​structure.

[0061] In this application, the cover plate 4 is provided with a snap-fit ​​structure, which passes through the sealing strip 3 and snaps against the rear door assembly 2. This is used to press the sealing strip 3 against the front end face of the rear door assembly 2, thereby ensuring the connection stability between the cover plate 4 and the sealing strip 3. It should be noted that since the snap-fit ​​structure penetrates inside the sealing strip 3, a clearance structure is provided at the corresponding position on the connecting body of the sealing strip 3. The clearance structure provides a connection basis for the effective snap-fit ​​between the cover plate 4 and the rear door assembly 2.

[0062] As a specific embodiment of the above-mentioned snap-fit ​​structure, the snap-fit ​​structure consists of a snap-fit ​​block and a connecting hole. The snap-fit ​​block has a first part with a size larger than that of the connecting hole and a second part with a size equal to that of the connecting hole. By pressing the cover plate 4 with force, the first part of the snap-fit ​​block can pass through the connecting hole. After the first part passes through the connecting hole, the second part abuts against the peripheral wall of the connecting hole. At this time, the first part can limit the snap-fit ​​block and the connecting hole.

[0063] As another specific implementation of the above-mentioned snap-fit ​​structure, please refer to Figures 5 to 8 The snap-fit ​​structure includes multiple sets of limiting clips 43, multiple sets of first clearance holes 33, and multiple sets of snap-fit ​​holes 2311. The multiple sets of limiting clips 43 are spaced vertically on the side of the cover plate 4 facing the sealing strip 3. The limiting clips 43 are provided with first grooves 433 and second grooves 434 spaced vertically along the front-back direction. The multiple sets of first clearance holes 33 are spaced vertically on the sealing strip 3 and correspond one-to-one with the multiple sets of limiting clips 43. The multiple sets of snap-fit ​​holes 2311 are spaced vertically on the front end face of the rear door assembly 2 and correspond one-to-one with the multiple sets of limiting clips 43. When the end of the limiting clip 43 away from the cover plate 4 is snapped into the rear door assembly 2, the hole wall of the first clearance hole 33 is limited in the first groove 433, and the hole wall of the snap-fit ​​hole 2311 is limited in the second groove 434.

[0064] By setting multiple sets of limit clips 43, the cover plate 4 and the front end face of the rear door assembly 2 can be engaged. When the limit clip 43 is engaged in the rear door assembly 2, the limit clip 43 has a first groove 433 that cooperates with the corresponding first clearance hole 33, and a second groove 434 that cooperates with the corresponding engagement hole 2311, so as to realize the second-level clamping of the limit clip 43, thereby improving the connection stability between the cover plate 4 and the front end face of the rear door assembly 2, enhancing the sealing effect of the sealing strip 3, and reducing the noise generated during driving.

[0065] Preferably, there are two sets of limit cards 43, which are arranged vertically at intervals to limit the upper and lower ends of the sealing strip 3 respectively.

[0066] Specifically, the sealing strip 3 is provided with a plurality of first clearance holes 33, and the plurality of first clearance holes 33 are provided in a one-to-one correspondence with a plurality of snap-fit ​​holes 2311; optionally, the size of the first clearance hole 33 is equal to the size of the snap-fit ​​hole 2311, so that the limiting card 43 on the cover plate 4 can pass through the clearance holes and enter the snap-fit ​​hole 2311; at this time, the width of the first groove 433 and the second groove 434 in the front-back direction is equal, and is equal to the width of the first clearance hole 33 and the snap-fit ​​hole 2311.

[0078] Specifically, the front door assembly 1 has a rear end face, and the rear door assembly 2 has a front end face opposite to the front door assembly 1. A door gap space is formed between the rear end face of the front door assembly 1 and the front end face of the rear door assembly 2. The sealing strip 3 and the cover plate 4 are respectively sandwiched in the door gap space. The sealing strip 3 abuts against the front end face of the rear door assembly 2, and the cover plate 4 presses the sealing strip 3 tightly against the front end face of the rear door assembly 2.

[0079] The door assembly provided in this application embodiment includes the aforementioned door gap sealing component, and therefore has all the beneficial effects of the aforementioned door gap sealing component. It can improve the connection strength of the sealing component at the joint between the front door assembly 1 and the rear door assembly 2, ensure the sealing performance of the sealing strip 3, and reduce noise during driving.

[0080] For example, the front door assembly 1 includes a front door sheet metal 11, a front exterior trim panel 13 located on the outer side of the front door sheet metal 11, and a front interior trim panel 12 located on the inner side of the front door sheet metal 11; wherein, a first connecting plate 131 parallel to and opposite to the first flange 231 is connected to the front exterior trim panel 13; the first bent portion 31 abuts against the portion of the front exterior trim panel 13 extending rearward beyond the first connecting plate 131; the specific structure of the front door assembly 1 can be found in the appendix. Figure 2 .

[0081] Specifically, the side of the first connecting plate 131 opposite to the first flange 231 is the rear end face of the front door assembly 1; the front door sheet metal 11 and the front interior trim panel 12 both extend rearward to the first connecting plate 131, and the front interior trim panel 12 and the first connecting plate 131 clamp the edge of the front door sheet metal 11 to achieve the connection of the front door assembly 1.

[0082] Additionally, it should be understood that the front exterior trim panel 13 has a connecting portion that extends rearward over the first connecting plate 131, and when the front door is closed, the first bent portion 31 abuts against the connecting portion of the front exterior trim panel 13, thereby forming a sealed connection between the front door assembly 1 and the sealing strip 3.

[0083] Please see Figure 2 In some possible embodiments, the rear door assembly 2 includes a rear door sheet metal 21, a rear exterior trim panel 23 located outside the rear door sheet metal 21, and a rear interior trim panel 22 located inside the rear door sheet metal 21; wherein the rear exterior trim panel 23 has a first flange 231 that bends inward and extends to the rear door sheet metal 21, and a sealing strip 3 abuts against the first flange 231; a second bend 32 is clamped between the rear door sheet metal 21 and the rear interior trim panel 22.

[0084] It should be understood that the rear door sheet metal 21 is the main supporting structure of the rear door, the rear interior trim panel 22 is used to decorate the inner side of the rear door sheet metal 21, and the rear exterior trim panel 23 is used to decorate the outer side of the rear door sheet metal 21; the side of the first flange 231 away from the rear door sheet metal 21 forms the front end face of the rear door assembly 2, and the snap-fit ​​structure in this application is connected to the first flange 231 of the rear exterior trim panel 23; specifically, the first flange 231 is connected to the cover plate 4 through the snap-fit ​​structure.

[0085] The first flange 231 forms the front end face of the rear door assembly 2 on the side facing the sealing strip 3. The first flange 231 is used to realize the snap-fit ​​limit between the rear door assembly 2 and the cover plate 4 through the above-mentioned snap-fit ​​structure. That is, through the connection between the rear outer trim panel 23 and the cover plate 4, the cover plate 4 presses the sealing strip 3, ensuring the connection stability of the sealing strip 3.

[0086] The second bend 32 extends between the rear door sheet metal 21 and the rear interior trim panel 22, and clamps the second bend 32 of the sealing strip 3 between the rear door sheet metal 21 and the rear interior trim panel 22. On the one hand, the second bend 32 can be fixed and positioned to prevent the sealing strip 3 from loosening and further enhance the stability of the connection of the sealing strip 3. On the other hand, it can realize the transition connection between the rear door assembly 2 and the inner side of the sealing strip 3, and hide the end of the second bend 32 of the sealing strip 3 between the rear door sheet metal 21 and the rear interior trim panel 22, which can further improve the aesthetics of the connection.

[0087] Please see Figure 2 In some embodiments, the rear interior trim panel 22 has an outwardly bent second flange 221 that abuts against the inside of the second bend 32.

[0088] By setting the second flange 221, it is convenient for the rear interior panel 22 to be pressed outward onto the second bend 32 of the sealing strip 3, while ensuring the aesthetics of the connection between the rear interior panel 22 and the second bend 32.

[0089] Specifically, the second flange 221 provided on the rear interior panel 22 is bent outward, so an outward pressure can be applied to the second bent portion 32 of the sealing strip 3, thereby pressing the second bent portion 32 of the sealing strip 3 onto the rear door sheet metal 21.

[0090] It should be understood that the first limiting part 41 of the cover plate 4 presses outward to the front end of the second bending part 32, and the second flange 221 presses outward to the rear end of the second bending part 32. The first limiting part 41 and the second flange 221 work together to achieve front and rear pressing and limiting of the second bending part 32, forming a double front and rear limiting, enhancing the stability of the connection of the second bending part 32, so as to ensure the sealing effect of the sealing strip 3.
