Description

Technical Field

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

[0002] The tailgate sealing strip is one of the core components of a car's body sealing system. It is primarily installed on the tailgate frame (or the edge of the tailgate body). Through a tight fit with the tailgate and body frame, it achieves five core functions: waterproofing, dustproofing, sound insulation, heat insulation, and cushioning, while also ensuring the stability and comfort of the tailgate's closure. However, insufficient matching between the sealing strip and surrounding components results in a poor aesthetic appearance, hindering the improvement of the vehicle's overall quality. Utility Model Content

[0003] In view of this, this application aims to propose a sealing structure that can improve the overall quality of a vehicle.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: A sealing structure is provided on a vehicle door, including a sealing strip provided on the vehicle door; The sealing strip includes a main body, a snap-fit ​​structure on one side of the main body, and a sealing part on the other side of the main body; The snap-fit ​​structure snaps into the recessed part on the door, the sealing part is used to abut against the door opening of the vehicle body and form a sealing fit, and a reinforcing member extending along the length direction of the main body is embedded in the main body.

[0005] Furthermore, the snap-fit ​​structure includes at least two snap-fit ​​claws disposed on the main body, with each snap-fit ​​claw arranged at intervals on the main body; the recessed portion includes multiple grooves disposed on the door, with the snap-fit ​​ends of each snap-fit ​​claw correspondingly snapping into each groove.

[0006] Furthermore, each of the claws includes a connecting arm connected to the main body, and the snap-fit ​​end of each claw includes a first snap-fit ​​unit and a second snap-fit ​​unit disposed on the corresponding connecting arm; in each claw, the first snap-fit ​​unit and the second snap-fit ​​unit are disposed on both sides of the corresponding connecting arm, and the first snap-fit ​​unit and the second snap-fit ​​unit are engaged with the inner wall of the corresponding groove.

[0007] Furthermore, each of the first latching units includes a latching protrusion connected to the corresponding connecting arm, and the latching protrusions in two adjacent latches are arranged opposite to each other.

[0008] Furthermore, each of the second snap-fit ​​units includes a snap-fit ​​lip connected to the corresponding connecting arm, and each snap-fit ​​lip is bent toward the main body relative to the corresponding connecting arm.

[0009] Furthermore, each of the grooves has a stop protrusion at its opening that protrudes into the groove, and the stop protrusion is located on the side of the groove that engages with the snap-fit ​​lip.

[0010] Furthermore, an angle is formed between the end face of the engaging end of each of the claws and the bottom surface of the corresponding groove.

[0011] Furthermore, the door has a door sheet metal and a door glass, and the recessed portion is provided on the door sheet metal; the sealing portion includes a first lip and a second lip spaced apart on the main body; the first lip is close to the door glass and seals with the door opening of the vehicle body, and the second lip is located on the side of the first lip away from the door glass, and / or, the main body has a third lip extending toward the door glass, the third lip being used to cover the gap between the door glass and the door sheet metal.

[0012] Furthermore, the sealing strip is integrally formed; and / or, the reinforcing component includes fiber filaments embedded in the main body.

[0013] Compared with related technologies, this application has the following advantages: (1) The sealing structure described in this application, by setting a snap-fit ​​structure on the sealing strip and setting an inner recess on the car door that snaps into the snap-fit ​​structure, can improve the matching between the sealing strip and the surrounding parts, making the appearance transition between the sealing strip and the surrounding parts smooth and consistent, solving the problem of poor appearance refinement. At the same time, the sealing part on the sealing strip can also ensure the sealing between the car door and the car body door opening. Furthermore, the setting of the reinforced parts can also improve the structural strength of the sealing strip, which helps the sealing strip to have better sealing fit and structural stability, thereby improving the overall quality of the vehicle.

[0014] (2) By inserting the snap-fit ​​ends of each snap-fit ​​into each groove one by one, it is easy to snap the sealing strip on the door. At the same time, the snap-fits are arranged at intervals on the main body, which can also help to disperse the reaction force of the snap-fit ​​points on the sealing strip and avoid the sealing strip being difficult to install or lifting up.

[0015] (3) The claw includes a connecting arm, and a first snap-fit ​​unit and a second snap-fit ​​unit respectively disposed on both sides of the connecting arm. The first snap-fit ​​unit and the second snap-fit ​​unit are engaged with the inner wall of the corresponding groove, thereby forming two snap-fit ​​points, which improves the snap-fit ​​stability of the claw and the groove. The structure is simple and easy to prepare and implement.

[0016] (4) By setting the snap-fit ​​protrusions in two adjacent snap-fit ​​claws relative to each other, two adjacent snap-fit ​​claws can form a snap-fit ​​unit and snap-fit ​​into the connection area between two adjacent grooves, thereby improving the snap-fit ​​reliability of the snap-fit ​​structure and the inner recess, that is, improving the snap-fit ​​reliability of the sealing strip on the car door.

[0017] (5) By making each second snap-fit ​​unit include a snap-fit ​​lip connected to the corresponding connecting arm, and each snap-fit ​​lip bends toward the main body relative to the corresponding connecting arm, the design of the snap-fit ​​lip bending toward the main body is advantageous, making it easy for the snap-fit ​​claw to snap into the groove. At the same time, it can also generate a large friction force when the snap-fit ​​claw leaves the groove, which can prevent the snap-fit ​​claw from coming out, thereby helping to improve the snap-fit ​​reliability of the snap-fit ​​claw.

[0018] (6) Each groove opening is provided with a blocking protrusion protruding into the groove, and the blocking protrusion is located on the side of the groove that engages with the locking lip. When the locking claw disengages from the groove, the blocking protrusion blocks the locking lip and prevents the locking claw from disengaging.

[0019] (7) This makes it possible for an angle to be formed between the end face of each claw and the bottom surface of the corresponding groove. This not only makes it easier for each claw to be inserted into the corresponding groove, improving the ease of installation and removal of the sealing strip, but also facilitates the formation of a setting where the claw lip bends toward the main body relative to the corresponding connecting arm.

[0020] (8) By approaching the door glass with the first lip and sealing it with the door opening, the airtightness between the door and the door opening can be ensured. At the same time, a third lip extending towards the door glass is provided on the main body, which can cover the gap between the door glass and the door sheet metal, which helps to improve the overall appearance of the vehicle.

[0021] (9) The sealing strip is integrally molded, which can improve the molding quality and increase durability. At the same time, the reinforcing components, including the embedded fiber filaments, can improve the overall strength of the sealing strip, which helps the sealing strip to have better sealing fit and structural stability. It can also prevent the sealing strip from shrinking during use and reduce the risk of temperature adversely affecting the use of the sealing strip, thereby improving the sealing performance and durability of the sealing strip.

[0022] This application also proposes a vehicle having a sealing structure as described above.

[0023] The vehicle described in this application is equipped with the aforementioned sealing structure, which can improve the matching between the sealing strip and the door while ensuring sealing performance. This can help improve the overall appearance and refinement of the door, thereby improving the overall quality of the vehicle. Attached Figure Description

[0025] To make the technical solution and advantages of 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 not intended to limit the scope of this application.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0027] Furthermore, it should be noted that in the description of this application, if terms such as "upper," "lower," "inner," or "outer" appear, indicating orientation or positional relationship, these are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not 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 on this application. In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0029] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] 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.

[0031] An embodiment of the first aspect of this application provides a sealing structure that can improve the matching between the sealing strip 100 and the surrounding parts, solve the problem of poor appearance refinement, and thus help improve the overall quality of the vehicle.

[0032] In related technologies, the tailgate sealing strip 100 is one of the core components of the automotive body sealing system. It is mainly installed on the tailgate frame (or the edge of the tailgate body). Through its tight fit with the tailgate and the body frame, it achieves five core functions: waterproofing, dustproofing, sound insulation, heat insulation, and buffering, while ensuring the stability and comfort of tailgate closure.

[0033] However, the aforementioned sealing strip 100 does not match well with surrounding components, resulting in a poor appearance. In particular, when using bubble tube sealing or when the sealing strip 100 is snapped together and sealed with clips, appearance problems such as bubble tube collapse and corner deformation of the sealing strip 100 are prone to occur, which is not conducive to improving the appearance and thus not conducive to improving the overall quality of the vehicle.

[0034] In view of this, in order to overcome the shortcomings of related technologies, the sealing structure of this embodiment combines... Figure 1 and Figure 2 As shown in the figure, in terms of overall design, it is installed on the door 200 and includes a sealing strip 100 installed on the door 200.

[0035] The sealing strip 100 includes a main body 101, a snap-fit ​​structure on one side of the main body 101, and a sealing part on the other side of the main body 101. The snap-fit ​​structure snaps into a recess in the door 200, the sealing part abuts against the door opening 300 of the vehicle body to form a sealing fit, and a reinforcing member extending along the length direction of the main body 101 is embedded in the main body 101.

[0036] Therefore, by setting a snap-fit ​​structure on the sealing strip 100 and a recessed part on the door 200 that snaps into the snap-fit ​​structure, the matching between the sealing strip 100 and the surrounding parts can be improved, making the appearance transition between the sealing strip 100 and the surrounding parts smooth and consistent, solving the problem of poor appearance refinement. At the same time, the sealing part on the sealing strip 100 can also ensure the sealing between the door 200 and the door opening 300 of the vehicle body. Furthermore, the setting of the reinforced parts can also improve the structural strength of the sealing strip 100, which helps the sealing strip 100 to have better sealing fit and structural stability, thereby improving the overall quality of the vehicle.

[0037] Based on the above general introduction, specifically, in some exemplary embodiments, the door 200 of this embodiment can be specifically the left front door, right front door, left rear door, right rear door or tailgate (also known as tailgate) of a vehicle, and is particularly applicable to tailgates.

[0038] It should be noted that the direction-related descriptions in this embodiment are merely illustrative. In actual implementation, the direction descriptions in this embodiment will vary depending on the specific implementation. Figure 1 The orientation of the sealing strip 100 varies depending on the state shown; that is, the orientations in this embodiment refer to the orientation of the sealing strip 100. Figure 1 The relative coordinate system is based on the sealing strip 100 in the state shown.

[0039] For example, in this embodiment, the width direction of the sealing strip 100 is... Figure 1 In the state shown, the left and right directions correspond to the thickness direction of the sealing strip 100. Figure 1 In the state shown, the vertical direction and the length direction of the sealing strip 100 are... Figure 1 In the state shown Figure 1 The normal direction of the plane shown is important to note, however, that the term "normal direction" here is primarily used to illustrate the length direction of the sealing strip 100. Figure 1 and Figure 2 The diagram only shows a cross-sectional view of the sealing strip 100; it does not mean that the length of the sealing strip 100 must be a straight line. In practice, when the sealing strip 100 has corners... Figure 1 The normal to the plane shown is variable.

[0040] Continue to combine Figure 1 and Figure 2 As shown, in some exemplary embodiments, the snap-fit ​​structure includes at least two snap claws 102 disposed on the main body 101, with the snap claws 102 spaced apart on the main body 101. Furthermore, the recess includes a plurality of grooves 2011 disposed on the door 200, with the snap-fit ​​ends of each snap claw 102 correspondingly snapping into each groove 2011.

[0041] It is understandable that by inserting the snap-fit ​​ends of each snap-fit ​​claw 102 into each corresponding groove 2011, it is possible to snap the sealing strip 100 onto the door 200. At the same time, the snap-fit ​​claws 102 are arranged at intervals on the main body 101, which can also help to disperse the reaction force of the snap-fit ​​points on the sealing strip 100, and avoid the sealing strip 100 being difficult to install or lifting up.

[0042] In practice, the number and arrangement of the claws 102 can be set and adjusted according to the actual snapping requirements of the sealing strip 100. At this time, the number and arrangement of the grooves 2011 can be adapted to the claws 102. For example, if the claws 102 are two spaced apart on the main body 101 along the width direction of the sealing strip 100, the reliability of the snapping of the sealing strip 100 can be ensured, and the simplified design of the sealing strip 100 can be achieved, which is beneficial to the preparation and cost reduction of the sealing strip 100.

[0043] Continue to combine Figure 1 and Figure 2 As shown, in some exemplary embodiments, each claw 102 includes a connecting arm 1021 on the connecting body 101, and the snap-fit ​​end in each claw 102 includes a first snap-fit ​​unit and a second snap-fit ​​unit disposed on the corresponding connecting arm 1021.

[0044] Specifically, in each claw 102, the first locking unit and the second locking unit are respectively disposed on both sides of the corresponding connecting arm 1021, and the first locking unit and the second locking unit are engaged with the inner wall of the corresponding groove 2011.

[0045] The main advantage of this design is that it allows both the first and second snap-fit ​​units to engage with the inner wall of the corresponding groove 2011, thereby forming two snap-fit ​​points. This improves the snap-fit ​​stability of the claw 102 and the groove 2011, and the structure is simple, making it easy to manufacture and implement.

[0046] In specific implementation, we will continue to combine Figure 1 and Figure 2 As shown, in some exemplary embodiments, each first snap-fit ​​unit includes a snap-fit ​​protrusion 1022 connected to the corresponding connecting arm 1021, and the snap-fit ​​protrusions 1022 in two adjacent snap-fit ​​claws 102 are arranged opposite to each other.

[0047] Here, by having the snap-fit ​​protrusions 1022 in two adjacent snap-fit ​​claws 102 arranged opposite to each other, the two adjacent snap-fit ​​claws 102 can form a snap-fit ​​unit, which snaps into the connection area between two adjacent grooves 2011, thereby improving the snap-fit ​​reliability between the snap-fit ​​structure and the inner recess, that is, improving the snap-fit ​​reliability of the sealing strip 100 on the door 200.

[0048] In addition, continue to combine Figure 1 and Figure 2 As shown, in some of the exemplary embodiments, each second snap-fit ​​unit includes a snap-fit ​​lip 1023 connected to the corresponding connecting arm 1021, and each snap-fit ​​lip 1023 is bent toward the main body 101 relative to the corresponding connecting arm 1021.

[0049] It can be understood that by making each second snap-fit ​​unit include a snap-fit ​​lip 1023 connected to the corresponding connecting arm 1021, and each snap-fit ​​lip 1023 bends toward the main body 101 relative to the corresponding connecting arm 1021, the design of the snap-fit ​​lip 1023 bending toward the main body 101 facilitates the snap-fit ​​claw 102 to snap into the groove 2011. At the same time, it can also generate a large frictional force when the snap-fit ​​claw 102 disengages from the groove 2011, preventing the snap-fit ​​claw 102 from disengaging, thereby helping to improve the snap-fit ​​reliability of the snap-fit ​​claw 102.

[0050] In practical implementation, to facilitate the bending of the snap-fit ​​lip 1023 relative to the corresponding connecting arm 1021 towards the main body 101, that is... Figure 1 and Figure 2 As shown, in some of the exemplary embodiments, a recess may be provided on the side facing the main body 101 at the connection position between the snap-fit ​​lip 1023 and the connecting arm 1021 to guide the snap-fit ​​lip 1023 to bend toward the main body 101.

[0051] Continue to combine Figure 1 and Figure 2 As shown, in some of the exemplary embodiments, each groove 2011 has a stop protrusion 2012 protruding into the groove 2011 at the groove opening, and the stop protrusion 2012 is located on the side of the groove 2011 that engages with the snap-fit ​​lip 1023.

[0052] With this configuration, the blocking protrusion 2012 and the corresponding locking lip 1023 can form a blocking engagement, which can block the locking lip 1023 when the claw 102 is disengaged from the groove 2011, thus preventing the claw 102 from coming out.

[0053] In addition, continue to combine Figure 1 and Figure 2 As shown, in some exemplary embodiments, an angle α is formed between the end face of the snap-fit ​​end of each claw 102 and the bottom surface of the corresponding groove 2011.

[0054] This not only makes it easier for each claw 102 to engage with its corresponding groove 2011, improving the ease of assembly and disassembly of the sealing strip 100, but also facilitates the formation of a configuration where the snap-fit ​​lip 1023 bends toward the main body 101 relative to its corresponding connecting arm 1021.

[0055] In some exemplary embodiments, the value of the included angle α can be specifically between 5 and 10°, and for example, 5°, 8° or 10°, in order to improve the snap-fit ​​convenience of the snap-fit ​​end of the claw 102.

[0056] In addition, continue to combine Figure 1 and Figure 2 As shown, in some of the exemplary embodiments, the door 200 has a door sheet metal 201 and a door glass 202, and a recess is provided on the door sheet metal 201, that is, the groove 2011 can be specifically formed on the door sheet metal 201.

[0057] Furthermore, the sealing portion includes a first lip 103 and a second lip 104 spaced apart on the main body 101. The first lip 103 is close to the door glass 202 and seals against the body door opening 300, while the second lip 104 is located on the side of the first lip 103 away from the door glass 202.

[0058] It can be understood that by placing the first lip 103 close to the door glass 202 and sealing it with the body door opening 300, the sealing performance between the door 200 and the body door opening 300 can be ensured. At the same time, the second lip 104 can, to a certain extent, isolate the first lip 103 from the erosion of dust, moisture, etc., and prevent the first lip 103 from being impacted under dynamic conditions. It also improves the sound insulation and heat insulation effects of the sealing structure.

[0059] Of course, to ensure the sealing effect of the second lip 104, a recessed structure, such as the one used for snapping the lip 1023, can be provided at the connection position between the second lip 104 and the main body 101. This guides the bending of the second lip 104, disperses the stress at the connection position, and ensures the uniformity of extrusion deformation, thereby improving the fit and durability of the second lip 104 with the vehicle body door opening 300. If necessary, the aforementioned recessed structure can also be provided on the first lip 103, which also provides good durability.

[0060] Continue to combine Figure 1 and Figure 2As shown, in some exemplary embodiments, the main body 101 has a third lip 105 extending toward the door glass 202, which covers the gap between the door glass 202 and the door sheet metal 201. By providing the third lip 105, the gap between the door glass 202 and the door sheet metal 201 can be covered, which helps to improve the overall appearance and refinement of the vehicle.

[0061] Meanwhile, in some exemplary embodiments, the sealing strip 100 is integrally molded, and may be integrally extruded, for example, using an extrusion process. Here, integral molding of the sealing strip 100 can improve molding quality and increase durability.

[0062] Continue to combine Figure 1 and Figure 2 As shown, in some exemplary embodiments, the reinforcing component includes fiber filaments 400 embedded in the main body 101. Specifically, the fiber filaments 400 extend along the length of the main body 101, that is, along the length of the sealing strip 100. This arrangement can improve the overall strength of the sealing strip 100, contributing to better sealing fit and structural stability. Simultaneously, it can prevent shrinkage of the sealing strip 100 during use and reduce the risk of adverse effects of temperature on its use, thereby improving the sealing performance and durability of the sealing strip 100.

[0063] In specific implementation, the aforementioned fiber filament 400 can be glass fiber filament 400. Furthermore, the sealing strip 100 in this embodiment is integrally formed and is snapped into the recessed portion of the car door 200 via a snap-fit ​​structure. This not only improves the compatibility of the sealing strip 100 with surrounding components, but also, compared to the snap-fit ​​or adhesive connection methods used in traditional technologies, allows for easy installation and matching without the need for additional components, thus reducing costs.

[0064] Furthermore, in some exemplary embodiments, the main body 101, the third lip 105, and each claw 102 of this embodiment can all be made of solid adhesive to ensure that the sealing strip 100 as a whole has good structural strength and resistance to deformation, which is beneficial to improving its snap-fit ​​reliability and durability. At the same time, the first lip 103 and the second lip 104 can be made of sponge adhesive to have better elasticity and compression performance, improve sealing accuracy, and reduce friction loss and the risk of abnormal noise.

[0065] 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... Figure 1 and Figure 2As shown, it is disposed on the door 200 and may include, for example, a sealing strip 100 disposed on the door 200.

[0066] The sealing strip 100 includes a main body 101, a snap-fit ​​structure on one side of the main body 101, and a sealing part on the other side of the main body 101; the snap-fit ​​structure snaps into the recess on the door 200, the sealing part abuts against the door opening 300 of the vehicle body and forms a sealing fit, and a reinforcing member extending along the length direction of the main body 101 is embedded in the main body 101.

[0067] The snap-fit ​​structure includes two snap-fit ​​claws 102 on the main body 101, with each snap-fit ​​claw 102 arranged at intervals on the main body 101; the recessed portion includes two grooves 2011 on the door 200, with the snap-fit ​​ends of each snap-fit ​​claw 102 correspondingly snapping into each groove 2011.

[0068] Each claw 102 includes a connecting arm 1021 connected to the main body 101, and the snap-fit ​​end of each claw 102 includes a first snap-fit ​​unit and a second snap-fit ​​unit disposed on the corresponding connecting arm 1021; and in each claw 102, the first snap-fit ​​unit and the second snap-fit ​​unit are respectively disposed on both sides of the corresponding connecting arm 1021, and the first snap-fit ​​unit and the second snap-fit ​​unit form a snap-fit ​​engagement with the inner wall of the corresponding groove 2011.

[0069] Each of the first snap-fit ​​units includes a snap-fit ​​protrusion 1022 connected to the corresponding connecting arm 1021, and the snap-fit ​​protrusions 1022 in two adjacent snap-fit ​​claws 102 are arranged opposite to each other.

[0070] Each of the second snap-fit ​​units includes a snap-fit ​​lip 1023 connected to the corresponding connecting arm 1021, and each snap-fit ​​lip 1023 is bent toward the main body 101 relative to the corresponding connecting arm 1021.

[0071] Each groove 2011 has a stop protrusion 2012 protruding into the groove 2011 at the groove opening, and the stop protrusion 2012 is located on the side of the groove 2011 that engages with the snap-fit ​​lip 1023.

[0072] Among them, an included angle α is formed between the end face of the snap-fit ​​end of each claw 102 and the bottom surface of the groove 2011 corresponding to it; the value of the included angle α can be between 5-10°, and for example, it can be 5°, 8° or 10°.

[0073] The door 200 has a door sheet metal 201 and a door glass 202, with a recessed portion provided on the door sheet metal 201; the sealing portion includes a first lip 103 and a second lip 104 spaced apart on the main body 101; the first lip 103 is close to the door glass 202 and seals with the body door opening 300, and the second lip 104 is located on the side of the first lip 103 away from the door glass 202; at the same time, the main body 101 has a third lip 105 extending toward the door glass 202, the third lip 105 being used to cover the gap between the door glass 202 and the door sheet metal 201.

[0074] The sealing strip 100 is integrally formed; and the reinforcing component includes fiber filaments 400 embedded in the main body 101.

[0075] In the preferred embodiment of the sealing structure above, the specific setting and arrangement of the sealing strip 100, the door sheet metal 201, the body door opening 300, 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 sealing strip 100, the door sheet metal 201, and the body door opening 300 can also be referred to the description in the above exemplary embodiments.

[0076] The sealing structure of this embodiment adopts the above design. By providing a recessed part on the door 200 that engages with the snap-fit ​​structure, the matching between the sealing strip 100 and the surrounding parts can be improved, making the appearance transition between the sealing strip 100 and the surrounding parts smooth and consistent, thus solving the problem of poor appearance refinement. At the same time, the sealing part provided on the sealing strip 100 can also ensure the sealing between the door 200 and the door opening 300 of the vehicle body.

[0077] Furthermore, by having the snap-fit ​​protrusions 1022 in adjacent snap-fit ​​claws 102 arranged opposite to each other, the two adjacent snap-fit ​​claws 102 can form a snap-fit ​​unit, snapping into the connection area between the two adjacent grooves 2011, thereby improving the snap-fit ​​reliability between the snap-fit ​​structure and the inner recess. By bending the snap-fit ​​lip 1023 towards the main body 101 relative to the corresponding connecting arm 1021, it not only facilitates the snap-fit ​​lip 1023 bending towards the main body 101, making it easier for the snap-fit ​​claws 102 to snap into the grooves 2011, but also generates greater friction when the snap-fit ​​claws 102 disengage from the grooves 2011, preventing the snap-fit ​​claws 102 from falling out, thus helping to improve the snap-fit ​​reliability of the snap-fit ​​claws 102.

[0078] Meanwhile, by setting the blocking protrusion 2012, the locking lip 1023 can be blocked when the claw 102 disengages from the groove 2011, preventing the claw 102 from falling out. By having the first lip 103 close to the door glass 202 and sealingly engaging with the body door opening 300, the sealing between the door 200 and the body door opening 300 can be ensured. The third lip 105 can cover the gap between the door glass 202 and the door sheet metal 201, which helps to improve the overall appearance and refinement of the vehicle.

[0079] An embodiment of the second aspect of this application provides a vehicle that is equipped with the sealing structure of the embodiment of the first aspect of this application.

[0080] The vehicle in this embodiment, by setting the sealing structure in the embodiment of the first aspect of this application, can not only ensure the sealing between the door 200 and the body door opening 300, but also improve the matching between the sealing strip 100 and the door 200, solve the problem of poor appearance refinement, thereby improving the overall quality of the vehicle.

[0081] 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.
