Description

Technical Field

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

[0002] There is a gap between the vehicle door and the fender. To meet the vehicle's sound insulation and waterproofing requirements, a weatherstripping is usually installed on the side of the door facing the fender. When the door is closed, the weatherstripping is pressed against the fender, sealing the gap between the door and the fender. The installation method for the weatherstripping generally involves using clips that pass through the weatherstripping and snap onto the door, pressing the weatherstripping firmly against the door.

[0003] However, this type of sealing strip assembly results in the buckle being exposed. As people's requirements for vehicle appearance continue to increase, the exposed buckle will undoubtedly affect the appearance of the door when it is opened, impacting the sense of refinement and hindering the improvement of the door's appearance quality. Utility Model Content

[0004] In view of this, this application aims to propose a sealing strip to improve the appearance quality of vehicle doors.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A sealing strip for sealing the gap between a vehicle door and a fender, the sealing strip comprising a sealing strip body for sealing the gap, a plurality of mounting brackets disposed on the sealing strip body, and a plurality of snap-fit ​​parts disposed on each of the mounting brackets; Multiple mounting brackets are arranged at intervals along the length of the sealing strip body. Along the left-right direction of the vehicle, each mounting bracket is located on the side of the sealing strip body facing outwards from the vehicle. Multiple snap-fit ​​components are respectively snap-fitted to the vehicle door, enabling the sealing strip to be installed on the vehicle door.

[0006] Furthermore, the sealing strip body includes a sealing strip skeleton and a first lip disposed on the sealing strip skeleton; Along the front-rear direction of the vehicle, the first lip is located on the first side of the sealing strip frame, and the first lip is used to abut against the first side of the door.

[0007] Furthermore, the sealing strip skeleton is provided with a second lip, which is located on the second side of the sealing strip skeleton along the front-rear direction of the vehicle. The second lip is used to abut against the fender.

[0008] Furthermore, the sealing strip skeleton includes a first sealing plate and a second sealing plate connected together, the first sealing plate being positioned on the inside of the door, and the second sealing plate being positioned on the side of the door facing the fender. Along the front-rear direction of the vehicle, the first lip is located on the side of the first sealing plate facing the first side, and the second lip is located on the side of the second sealing plate facing the fender. Each of the aforementioned mounting brackets is mounted on the first sealing plate.

[0009] Furthermore, the first sealing plate has a first recess on the side facing the first side, and the first lip includes a first embedded portion that is embedded in the first recess.

[0010] Furthermore, the second sealing plate has a second recess on the side facing the fender, and the second lip includes a second embedded portion that is embedded in the second recess.

[0011] Furthermore, the sealing strip skeleton has a reinforcing rib on the side facing the door, and the reinforcing rib is connected between the first sealing plate and the second sealing plate.

[0012] Furthermore, at least one of the surfaces of the first lip and the second lip is coated with a wear-resistant layer.

[0013] Furthermore, each of the mounting brackets includes a mounting plate and a connecting plate for connecting the mounting plate to the sealing strip frame, and the snap-fit ​​component is detachably connected to the mounting plate.

[0014] Furthermore, the mounting plate is provided with a first snap-fit ​​hole and a notch located on one side of the first snap-fit ​​hole, and the snap-fit ​​component is inserted into the first snap-fit ​​hole through the notch.

[0015] Furthermore, the car door is provided with a second snap-fit ​​hole, which corresponds one-to-one with the snap-fit ​​component, and each snap-fit ​​component includes a buckle that snaps into the corresponding second snap-fit ​​hole.

[0016] Furthermore, the sealing strip skeleton is made of plastic.

[0017] Furthermore, the sealing strip skeleton and each of the mounting brackets are integrated into a single structure.

[0018] Compared with related technologies, this application has the following advantages: (1) The sealing strip described in this application can be installed on the car door by setting a sealing strip body and setting multiple mounting brackets on the sealing strip body, and using a snap-fit ​​component to snap the mounting brackets to the car door. The snap-fit ​​component and the bracket are located on the side of the sealing strip body facing the car door, which can effectively seal and securely install the gap between the car door and the fender. After the sealing strip is installed, the snap-fit ​​component and the bracket will not be exposed when the car door is opened, thus achieving the concealment of the snap-fit ​​component and the mounting bracket, which is conducive to improving the appearance quality of the car door and enhancing the level of refined perception.

[0019] (2) By setting the sealing strip body as a sealing strip skeleton and a first lip, the sealing strip skeleton can provide the sealing strip body with high structural strength. The first lip abuts against the first side of the car door, which can make the edge of the sealing strip form a smooth curved surface that transitions to the car door, reducing the abruptness of the sealing strip edge on the car door, which is conducive to improving the appearance quality of the car door.

[0020] (3) A second lip is provided on the second side of the sealing strip skeleton to press against the fender, which can block dust, rain and noise more comprehensively, further optimize the in-vehicle environment, and at the same time reduce the erosion of the door and fender connection by external factors, which helps to extend the service life of related components.

[0021] (4) The sealing strip skeleton is composed of a first sealing plate and a second sealing plate connected together. The first sealing plate is placed on the inside of the door and the second sealing plate is placed on the side of the door facing the fender. It can divide the various parts of the sealing strip skeleton and arrange the functions, making the sealing strip skeleton structure more reasonable and stable. The first sealing plate and the second sealing plate can cover the door from the inside of the door and the side facing the fender respectively, forming an "L" shaped cross-section structure. The structure is relatively compact and is conducive to improving the utilization rate of the interior space.

[0022] (5) A first recess is provided on the side of the first sealing plate facing the first side, which can position the first lip and provide installation space for the first embedded part for the connection between the first sealing plate and the first lip, which is conducive to improving the connection strength; a second recess is provided on the side of the second sealing plate facing the fender, which can position the second lip and provide installation space for the second embedded part for the connection between the second sealing plate and the second lip, which is conducive to improving the connection strength.

[0023] (6) A reinforcing rib is provided on the side of the sealing strip skeleton facing the door. The reinforcing rib connects the first sealing plate and the second sealing plate, which can enhance the overall strength and rigidity of the sealing strip skeleton, making it less prone to deformation under the impact force when the door is closed and various external forces during long-term use, thereby better ensuring the sealing effect; a wear-resistant layer is coated on at least one of the first lip and the second lip, which can improve the wear resistance of the lip, reduce wear caused by frequent friction with the door or fender, and extend the service life of the sealing strip.

[0024] (7) Each mounting bracket includes a mounting plate and a connecting plate that connects it to the sealing strip skeleton. The snap-fit ​​component is detachably connected to the mounting plate. This structural design makes the installation and removal of the snap-fit ​​component more convenient, which is conducive to improving production and maintenance efficiency and reducing maintenance costs.

[0025] (8) A first snap-fit ​​hole and a notch on one side are provided on the mounting plate. The snap-fit ​​component is inserted into the first snap-fit ​​hole through the notch, which facilitates the installation and fixation of the snap-fit ​​component and prevents the snap-fit ​​component from falling off accidentally to a certain extent, which helps to improve the installation reliability of the snap-fit ​​component. A second snap-fit ​​hole corresponding to the snap-fit ​​component is provided on the door, and each snap-fit ​​component includes a buckle that is snapped into the corresponding second snap-fit ​​hole. This snap-fit ​​structure helps to maintain the stability of the connection between the sealing strip and the door.

[0026] (9) The sealing strip skeleton is made of plastic material. Plastic material has the advantages of being lightweight, low cost and corrosion resistant, which helps to reduce the weight of the whole vehicle and reduce production costs. The sealing strip skeleton is integrated with each mounting bracket into a single structure, which can enhance the strength and stability of the overall structure and also help to improve the overall performance of the sealing strip.

[0027] Another object of this application is to provide a vehicle equipped with the aforementioned door sealing strip.

[0028] The vehicle described in this application, by having the aforementioned sealing strip on its own door, can effectively seal the gap between the vehicle door and the fender, and the sealing strip is securely installed. After the sealing strip is installed, when the door is opened, the snap-fit ​​parts and mounting brackets will not be exposed, thus achieving the concealment of the snap-fit ​​parts and mounting brackets. This is beneficial to improving the appearance quality of the door, enhancing the level of refinement, and thereby improving the appearance quality of the vehicle, making the vehicle more luxurious.

[0030] 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.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] An embodiment of the first aspect of this application provides a sealing strip for sealing the gap between the vehicle door and the fender, which helps to improve the appearance quality of the door.

[0037] It should be noted that the sealing strip in this embodiment can seal the gap between the front door and the front fender of the vehicle, and it can also seal the gap between the rear door and the rear fender of the vehicle. The following description uses the sealing strip between the front door and the front fender as an example. The sealing strip between the rear door and the rear fender has a similar structure and will not be described in detail below.

[0038] In the design of vehicle body structure, there is a gap between the car door and the fender when the car door is closed. This gap may seem narrow, but it is directly related to important functions such as sound insulation, waterproofing, and dustproofing. If it is not properly sealed, rainwater and dust from the outside will seep into the interior of the car body through the gap, which may not only damage the interior door parts and electrical components, but also cause a significant increase in interior noise, seriously affecting the driving experience of the passengers.

[0039] Therefore, in order to achieve effective isolation between the interior and exterior of the car, a sealing strip is usually installed on the side of the door facing the fender. After the door is closed, the sealing strip is squeezed by the fender and sealed between the door and the fender. Its elastic material will fully fill the gap between the two, thus achieving a seal between the door and the fender.

[0040] The mainstream installation method for weatherstripping in the industry is primarily clip-on fastening. Specifically, the installation method typically involves inserting clips through pre-drilled mounting holes in the weatherstripping, and then snapping the clips into the corresponding locking mechanism on the door. Through the tightening action of the clips, the weatherstripping fits snugly against the door's mounting surface. This assembly method is simple to operate, requiring no complex tools or processes, and is therefore widely used in the industry.

[0041] However, with the continuous upgrading of the automobile consumer market, consumers have significantly increased their requirements for vehicle quality, especially for the refinement of the appearance. This type of sealing strip assembly results in the buckle being exposed. When the user opens the car door, the exposed buckle will directly enter the field of vision, forming a stark contrast with the overall smooth lines and exquisite appearance design of the car body. This seriously affects the perception of the vehicle's refined appearance and is not conducive to improving the appearance quality of the car door.

[0042] In view of this, and to overcome the shortcomings of related technologies, in this embodiment, the sealing strip used to seal the gap between the vehicle door and the fender incorporates... Figures 1 to 3 In terms of overall design, it includes a sealing strip body 1 for sealing gaps, multiple mounting brackets 2 on the sealing strip body 1, and multiple snap-fit ​​parts 3 on each mounting bracket 2.

[0043] Multiple mounting brackets 2 are arranged at intervals along the length of the sealing strip body 1, and along the left-right direction of the vehicle, each mounting bracket 2 is located on the side of the sealing strip body 1 facing outwards. Multiple snap-fit ​​pieces 3 are respectively snapped and connected to the door 4, enabling the sealing strip to be installed on the door 4.

[0044] Therefore, by setting a sealing strip body 1 and installing multiple mounting brackets 2 on the sealing strip body 1, and then using a snap-fit ​​device 3 to snap the mounting brackets 2 onto the car door 4, the sealing strip can be installed on the car door 4. The snap-fit ​​device 3 and the brackets are located on the side of the sealing strip body 1 facing the car door, achieving effective sealing of the gap between the vehicle door 4 and the fender. The multiple mounting brackets 2 are arranged at intervals along the length of the sealing strip body 1 and are located on the side facing outwards. In conjunction with the snap-fit ​​device 3 that snaps onto the car door 4, this structural design ensures that the sealing strip remains stably installed during vehicle operation, which helps maintain good sealing of the gap between the car door 4 and the fender, effectively preventing external dust, rainwater, and noise from entering the vehicle.

[0045] Meanwhile, after the sealing strip is installed, when the door 4 is opened, the snap-fit ​​part 3 and the bracket will not be exposed, thus hiding the snap-fit ​​part 3 and the mounting bracket 2, making the front appearance of the door more concise and smooth, which helps to improve the appearance quality of the door and enhance the level of refinement.

[0046] Based on the above overview, specifically, the length direction of the sealing strip body 1 is the installation direction of the sealing strip on the door 4, and also the direction corresponding to the gap between the door 4 and the fender. The front-to-back direction of the vehicle is the length direction, the left-to-right direction is the width direction, and the up-and-down direction is the height direction.

[0047] As for the arrangement of the mounting bracket 2, the mounting bracket 2 can be paired with the snap-fit ​​piece 3 one by one, or one mounting bracket 2 can be paired with two or more snap-fit ​​pieces 3. Both of these mounting bracket 2 arrangements can make the sealing strip more securely installed on the car door 4.

[0048] The structure of door 4 typically includes an inner door panel 401 and an outer door panel 402. The outer door panel 402 is the exterior surface of door 4 facing the outside of the vehicle. The inner door panel 401 and the outer door panel 402 are usually connected by an edge-wrapping process, that is, the edge of the outer door panel 402 is folded 180° inward towards the inside of the vehicle, and the edge of the inner door panel 401 is pressed tightly against the inside of the outer door panel 402. The two panels are fixed by mechanical interlocking, and welding or adhesive can be used to enhance the connection strength.

[0049] It should be noted that the sealing strip in this embodiment can be used not only between the vehicle door 4 and the fender, but also between any side door of the vehicle and the body, or between the tailgate and the body. When the sealing strip is installed on the corresponding side door or tailgate in these positions, it has the function of hiding the snap-fit ​​3 and making the corresponding side door or tailgate have a higher appearance quality.

[0050] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the sealing strip body 1 includes a sealing strip skeleton 101 and a first lip 102 disposed on the sealing strip skeleton 101. Along the front-rear direction of the vehicle, the first lip 102 is disposed on a first side of the sealing strip skeleton 101, and the first lip 102 is used to abut against the first side 4011 of the door 4.

[0051] It should be noted that, for the sealing strip at the front door, the first side of the sealing strip skeleton 101 refers to the side of the sealing strip skeleton 101 facing rearward along the vehicle's front-rear direction, and the second side of the sealing strip skeleton 101 refers to the side of the sealing strip skeleton 101 facing forward along the vehicle's front-rear direction. The first side 4011 refers to the side of the front door facing forward of the vehicle.

[0052] Regarding the sealing strip at the rear door, the first side of the sealing strip frame 101 refers to the side of the sealing strip frame 101 facing forward along the vehicle's front-rear direction, and the second side of the sealing strip frame 101 refers to the side of the sealing strip frame 101 facing backward along the vehicle's front-rear direction. The first side 4011 refers to the side of the rear door facing the rear of the vehicle.

[0053] In this way, by setting the sealing strip body 1 in the form of sealing strip skeleton 101 and first lip 102, the sealing strip skeleton 101 can provide high structural strength to the sealing strip body 1 as a whole. The first lip 102 abuts against the first side 4011 of the car door 4, which can make the edge of the sealing strip form a smooth curved surface that transitions to the car door, reducing the abruptness of the sealing strip edge on the car door, which is conducive to improving the appearance quality of the car door.

[0054] Specifically, the cross-section of the first lip 102 can be set as an arc-shaped strip. The first lip 102 gradually bends inward towards the inside of the vehicle along the direction away from the sealing strip skeleton 101, and the curved end of the first lip 102 abuts against the inner door panel 401, relying on its own elasticity to press firmly against the inner door panel 401. On the cross-section of the first lip 102, the end away from the sealing strip skeleton 101 is a smoothly transitioned semi-circle. This shape can ensure a continuous contact surface between the first lip 102 and the inner door panel 401, resulting in a better sealing effect. The material of the first lip 102 can be, for example, TPV (Thermoplastic Vulcanizate), which has high elasticity similar to rubber and strong weather resistance, making it suitable as a material for sealing strips.

[0055] Reference Figures 1 to 4 Based on the first lip 102 on the sealing strip frame 101, in some exemplary embodiments, the sealing strip frame 101 is provided with a second lip 103. Along the front-rear direction of the vehicle, the second lip 103 is located on the second side of the sealing strip frame 101 and is used to abut against the fender.

[0056] With this configuration, a second lip 103 is provided on the second side of the sealing strip frame 101 to press against the fender, which can more comprehensively block dust, rain and noise, further optimize the in-vehicle environment, and at the same time reduce the erosion of external factors on the connection between the door and the fender, which helps to extend the service life of related components.

[0057] Specifically, the contact point between the second lip 103 and the door 4 is on the outer side of the folded portion of the outer door panel 402. Looking at the cross-section of the second lip 103, the portion connecting the second lip 103 to the sealing strip skeleton 101 is thicker, while the portion away from the sealing strip skeleton 101 is thinner. The thicker and thinner portions of the second lip 103 transition smoothly, and the thinner portion curves inwards towards the vehicle, making it easier for the second lip 103 to press firmly against the fender, thus maintaining a good seal between the second lip 103 and the fender. The material of the second lip 103 can be, for example, TPV, a material with high elasticity similar to rubber and strong weather resistance, making it suitable as a sealing strip material.

[0058] Based on the second lip 103 provided on the sealing strip frame 101, in some exemplary embodiments, the sealing strip frame 101 includes a first sealing plate 1011 and a second sealing plate 1012 connected together. The first sealing plate 1011 is positioned on the inner side of the door 4, and the second sealing plate 1012 is positioned on the side of the door 4 facing the fender. Along the front-rear direction of the vehicle, the first lip 102 is located on the side of the first sealing plate 1011 facing the first side 4011, and the second lip 103 is located on the side of the second sealing plate 1012 facing the fender. Each mounting bracket 2 is mounted on the first sealing plate 1011.

[0059] With this configuration, the first sealing plate 1011 is placed on the inside of the door 4, and the second sealing plate 1012 is placed on the side of the door 4 facing the fender. The sealing strip frame 101 is composed of the first sealing plate 1011 and the second sealing plate 1012 connected together. This configuration allows for the partitioning and arrangement of functions for each part of the sealing strip frame 101, making the structure of the sealing strip frame 101 more reasonable and stable.

[0060] Meanwhile, the first sealing plate 1011 and the second sealing plate 1012 can respectively cover the door 4 from the inside and the side facing the fender, forming an "L" shaped cross-section structure. This structure can better match the shape of the inner door panel 401, making the gap between the sealing strip and the inner door panel 401 smaller and the structure of the sealing strip connected to the door 4 more compact. This can increase the usable space inside the vehicle and improve the utilization rate of the interior space.

[0061] Specifically, the angle between the first sealing plate 1011 and the second sealing plate 1012 can be, for example, 94° to 104°, preferably 99°. Secondly, the first sealing plate 1011 and the second sealing plate 1012 have a smooth transition. Preferably, the first sealing plate 1011 and the second sealing plate 1012 can be designed as a single piece, and the corresponding angle can be formed using sheet metal methods.

[0062] Furthermore, in order to improve the connection strength between the first sealing plate 1011 and the first lip 102, based on the sealing strip skeleton 101 including the first sealing plate 1011 and the second sealing plate 1012, in some exemplary embodiments, the first sealing plate 1011 has a first recess 10111 on the side facing the first side 4011, and the first lip 102 includes a first embedding portion 1021 embedded in the first recess 10111.

[0063] This arrangement, with a first recess 10111 provided on the side of the first sealing plate 1011 facing the first side 4011, can position the first lip 102 and provide installation space for the first embedded part 1021 for the connection between the first sealing plate 1011 and the first lip 102, which helps to improve the connection strength.

[0064] Specifically, the first recess 10111 can be configured as a recessed stepped shape, and the first embedding portion 1021 on the first lip 102 is arranged as a stepped protrusion adapted to the shape of the first recess 10111. When the first embedding portion 1021 is embedded in the first recess 10111, there is essentially no gap between the first embedding portion 1021 and the first recess 10111, and the edge of the first lip 102 is flush with the first sealing plate 1011. The first embedding portion 1021 and the first recess 10111 can be bonded together to enhance the connection strength, or if the first embedding portion 1021 is made of rubber, it can be vulcanized onto the first recess 10111.

[0065] Continuing with the sealing strip skeleton 101 including a first sealing plate 1011 and a second sealing plate 1012, in some exemplary embodiments, in order to improve the connection strength between the second sealing plate 1012 and the second lip 103, a second recess 10121 is provided on the side of the second sealing plate 1012 facing the fender, and the second lip 103 includes a second embedded portion 1031 embedded in the second recess 10121.

[0066] In this way, a second recess 10121 is provided on the side of the second sealing plate 1012 facing the fender, which can position the second lip 103 and provide installation space for the second embedded part 1031 for the connection between the second sealing plate 1012 and the second lip 103, which helps to improve the connection strength.

[0067] Specifically, the second recess 10121 can be configured as a recessed stepped shape, and the second embedding portion 1031 on the second lip 103 is arranged as a stepped protrusion adapted to the shape of the second recess 10121. When the second embedding portion 1031 is embedded in the second recess 10121, there is essentially no gap between the second embedding portion 1031 and the second recess 10121, and the edge of the second lip 103 is flush with the second sealing plate 1012. The second embedding portion 1031 and the second recess 10121 can be bonded together to enhance the connection strength, or if the second embedding portion 1031 is made of rubber, it can be vulcanized onto the second recess 10121.

[0068] Still based on the sealing strip skeleton 101 including the first sealing plate 1011 and the second sealing plate 1012, in some exemplary embodiments, in order to enhance the structural strength between the first sealing plate 1011 and the second sealing plate 1012, the sealing strip skeleton 101 is provided with a reinforcing rib 1013 on the side facing the door 4, and the reinforcing rib 1013 is connected between the first sealing plate 1011 and the second sealing plate 1012.

[0069] With this arrangement, a reinforcing rib 1013 is provided on the side of the sealing strip skeleton 101 facing the car door 4. The reinforcing rib 1013 connects the first sealing plate 1011 and the second sealing plate 1012, which can enhance the overall strength and rigidity of the sealing strip skeleton 101, making it less prone to deformation under the impact force when the car door is closed and under various external forces during long-term use, thereby better ensuring the sealing effect.

[0070] For the specific form of the reinforcing rib 1013, for example, a reinforcing rib 1013 with a triangular cross section can be adopted. One right-angled side of the reinforcing rib 1013 is connected to the first sealing plate 1011, and the other right-angled side is connected to the second sealing plate 1012 to enhance the stability between the first sealing plate 1011 and the second sealing plate 1012. Multiple reinforcing ribs 1013 can be arranged at intervals along the length direction of the sealing strip body 1 to further enhance the strength of the sealing strip skeleton 101.

[0071] In practical implementation, during the opening and closing of the car door, friction occurs between the first lip 102 and the car door 4, and friction also occurs between the second lip 103 and the car door 4 and the fender. This friction may cause wear to the first lip 102 or the second lip 103, affecting the sealing of the sealing strip. Therefore, in some exemplary embodiments, a wear-resistant layer is coated on at least one of the surfaces of the first lip 102 and the second lip 103. The wear-resistant layer may be made of polyurethane, for example.

[0072] Polyurethane material has extremely high wear resistance, strong surface hardness and scratch resistance, and can effectively resist the frequent friction between the first lip 102 or the second lip 103 and the door 4 and fender. In addition, the polyurethane coating has strong weather resistance and can withstand various adverse external factors such as high and low temperature changes, rain erosion, ultraviolet radiation, and oil stains.

[0073] Regarding the specific form of the mounting bracket 2, in some exemplary embodiments, each mounting bracket 2 includes a mounting plate 201 and a connecting plate 202 that connects the mounting plate 201 to the sealing strip frame 101, and the snap-fit ​​member 3 is detachably connected to the mounting plate 201.

[0074] In this way, each mounting bracket 2 includes a mounting plate 201 and a connecting plate 202 that connects it to the sealing strip frame 101. The snap-fit ​​3 is detachably connected to the mounting plate 201. This structural design makes the installation and removal of the snap-fit ​​3 more convenient, which is conducive to improving production and maintenance efficiency and reducing maintenance costs.

[0075] Preferably, the mounting plate 201 can be arranged parallel to the first sealing plate 1011, and the connecting plate 202 is connected between one end of the mounting plate 201 and the first sealing plate 1011, so that the mounting bracket 2 is "L" shaped in the length direction of the sealing strip body 1.

[0076] Based on the mounting bracket 2, which includes the connecting plate 202 and the mounting plate 201, and referring to Figure 3 and Figure 4 In some exemplary embodiments, the mounting plate 201 is provided with a first snap-fit ​​hole 2011 and a notch 2012 located on one side of the first snap-fit ​​hole 2011, and the snap-fit ​​member 3 is snapped into the first snap-fit ​​hole 2011 through the notch 2012.

[0077] In this way, the mounting plate 201 has a first snap-fit ​​hole 2011 and a notch 2012 on one side. The snap-fit ​​part 3 is snapped into the first snap-fit ​​hole 2011 through the notch 2012, which can facilitate the installation and fixation of the snap-fit ​​part 3, and at the same time prevent the snap-fit ​​part 3 from falling off accidentally to a certain extent, which helps to improve the installation reliability of the snap-fit ​​part 3.

[0078] Specifically, for example, the first snap-fit ​​hole 2011 can be set as a circular hole, and the notch 2012 can be set as a rectangle, with the notch 2012 penetrating the mounting plate 201 in a direction away from the connecting plate 202. The width of the notch 2012 is smaller than the diameter of the first snap-fit ​​hole 2011, so that the snap-fit ​​member 3 can be more firmly snapped into the first snap-fit ​​hole 2011. The notch 2012 has rounded corners at the opening on the mounting plate 201, so that it can guide the snap-fit ​​member 3 when it is installed into the first snap-fit ​​hole 2011, making installation easier.

[0079] Corresponding to the snap-fit ​​3, in some exemplary embodiments of the door 4, the door 4 is provided with a second snap-fit ​​hole 4012, the second snap-fit ​​hole 4012 corresponds one-to-one with the snap-fit ​​3, and each snap-fit ​​3 includes a buckle that is snapped into the corresponding second snap-fit ​​hole 4012.

[0080] As described above, the door 4 is provided with second snap-fit ​​holes 4012 that correspond one-to-one with the snap-fit ​​pieces 3, and each snap-fit ​​piece 3 includes a buckle that snaps into the corresponding second snap-fit ​​hole 4012. This snap-fit ​​structure helps to maintain the stability of the connection between the sealing strip and the door 4 and maintain the sealing effect of the sealing strip.

[0081] Furthermore, regarding the material of the sealing strip frame 101, in some exemplary embodiments, the sealing strip frame 101 is made of plastic. Plastic has advantages such as light weight, low cost, and corrosion resistance, which helps to reduce the overall weight of the vehicle and reduce production costs.

[0082] The sealing strip skeleton 101 can be made of materials such as ABS plastic or ASA plastic. ABS plastic is a terpolymer of acrylonitrile, 1,3-butadiene, and styrene, possessing good weather resistance, adapting to the complex environment of vehicles, and having a low density. Its molding technology is also mature. ASA plastic is a synthetic resin made from acrylonitrile, styrene, and acrylate rubber through a graft copolymerization reaction. It also has good weather resistance and lightweight advantages, and a longer service life than ABS plastic.

[0083] Furthermore, regarding the molding structure of the sealing strip body 1, in some exemplary embodiments, the sealing strip skeleton 101 and each mounting bracket 2 are integrated into a single structure. This integration of the sealing strip skeleton 101 and each mounting bracket 2 into a single structure enhances the overall structural strength and stability, and also helps improve the overall performance and reliability of the sealing strip.

[0084] Additionally, for the form of card connector 3, refer to Figure 5 The content can be in the form of a snap fastener, which has a cap-shaped head and a flexible snap-fit ​​arm 301. The snap-fit ​​arm 301 has a stepped snap-fit ​​groove 3011. During specific installation, the inner door panel 401 and the mounting plate 201 are snapped into different snap-fit ​​grooves 3011 respectively.

[0085] It is worth noting that, regarding the sealing strip of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still made by... Figures 1 to 5 As shown, it may include, for example, a sealing strip body 1, a mounting bracket 2, and a snap-fit ​​component 3.

[0086] The sealing strip body 1 includes an "L"-shaped sealing strip skeleton 101, and a first lip 102 and a second lip 103 connected to both ends of the sealing strip skeleton 101. The first lip 102 abuts against the inner door panel 401, and the second lip 103 abuts against the edge of the outer door panel 402.

[0087] The sealing strip skeleton 101 includes a first sealing plate 1011 and a second sealing plate 1012, and a triangular reinforcing rib 1013 is provided between the first sealing plate 1011 and the second sealing plate 1012.

[0088] The mounting bracket 2 includes a connecting plate 202 and a mounting plate 201. The mounting plate 201 is provided with a first snap-fit ​​hole 2011 for snap-fitting the snap-fitting component 3.
