Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a sealing component and a vehicle. Background Technology

[0002] With the development of the automotive industry, the quality of car appearance has received high attention. In order to improve the sealing performance and appearance of the whole vehicle, adding auxiliary sealing strips to the rear door and rear wheel hub position has become a development trend.

[0003] Currently, some vehicle models have a vertical gap between the rear door and the outer side panel due to factors such as styling (e.g., wider wheel arches) and overall layout (e.g., the size of the door opening affects passenger access). In order to improve the overall appearance quality and NVH performance of the vehicle, a sealing strip needs to be added at the rear wheel hub position of the rear door (i.e., the rear door rear sealing strip). This sealing strip is used to prevent mud and sand on the tires from being thrown into the vehicle during driving, thus playing a sealing role.

[0004] In related technology, CN202121218569.7 provides an automotive wheel arch sealing strip and its installation structure. This automotive wheel arch sealing strip includes a snap-fit ​​body, a bubble tube, and a sealing lip. The snap-fit ​​body has an upward-opening snap-fit ​​groove inside. The snap-fit ​​body is provided with a guide lip and a snap-fit ​​lip, both disposed within the snap-fit ​​groove and positioned opposite each other. The upper side of the sealing lip connects to the lower side of the snap-fit ​​body, and the sealing lip slopes downwards from the outside to the inside. The bubble tube is disposed on the inner side of the snap-fit ​​body. This ensures sealing performance between the side wheel arch trim and the door sheet metal, as well as between the side wheel arch trim and the door sheet metal, preventing mud and sand from entering between the door sheet metal and the side wheel arch trim during vehicle operation, and preventing mud and sand from entering between the snap-fit ​​body and the inner door panel. However, in the related technology, there is a downward-facing gap between the side wheel arch trim and the door wheel arch trim. The wheel arch sealing strip is set in this gap and is in contact with both the side wheel arch trim and the door wheel arch trim. Therefore, when the vehicle is in motion, mud and sand on the tires can easily accumulate on the surface of the sealing strip in the gap through the opening, which seriously affects the user experience. Utility Model Content

[0005] One objective of this invention is to provide a sealing component to solve the problem of mud and sand accumulation on the surface of sealing strips in related technologies. A second objective of this invention is to provide a vehicle.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] In a first aspect, embodiments of this application provide a sealing assembly, including: a sealing strip, a wheel arch trim piece, and a side panel. The sealing strip includes: a first sealing portion and a second sealing portion connected to each other. The first sealing portion is disposed in contact with the wheel arch trim piece, and the second sealing portion is disposed in contact with the side panel. The edge of the wheel arch trim piece is disposed higher than the side panel.

[0008] According to the above technical means, since the first sealing part is in contact with the outer trim of the wheel arch and the second sealing part is in contact with the outer side panel, it can effectively block the mud and water splashed during vehicle operation and prevent them from entering the gap between the outer trim of the wheel arch and the outer side panel, thereby avoiding the mud and water from entering the vehicle or corroding the internal structure of the vehicle body.

[0009] In addition, since the edge of the wheel arch trim is set higher than the side panel, the edge of the wheel arch trim is set higher. As a result, when the vehicle is in motion, mud and sand on the tires will be thrown onto the outer surface of the wheel arch trim, thus preventing mud and sand from being thrown onto the sealing strip. This avoids the accumulation of mud and sand at the sealing strip and solves the problem of mud and sand being difficult to clean at the sealing strip during car washing, thereby improving the user experience.

[0010] In some embodiments, the sealing assembly further includes a snap-fit ​​element connected to a sealing strip; the sealing assembly also includes a door panel snap-fitted to the snap-fit ​​element and in contact with the sealing strip.

[0011] Based on the aforementioned technical means, the snap-fit ​​design simplifies the installation of the sealing assembly. Specifically, the snap-fit ​​method allows for quick and accurate installation of the sealing strip onto the door panel, reducing installation time and complexity, and improving production and maintenance efficiency. Furthermore, the snap-fit ​​design between the snap-fit ​​component and the door panel, as well as the contact design between the sealing strip and the door panel, ensures the stability of the sealing assembly during vehicle operation. Thus, under the vibration and external forces of vehicle operation, the risk of the sealing strip loosening or falling off is reduced, guaranteeing the reliability of the sealing assembly's seal.

[0012] In some embodiments, the sealing strip further includes a third sealing portion, which is connected to the second sealing portion and located on the side of the second sealing portion away from the first sealing portion, and at least a portion of the third sealing portion is disposed in contact with the door panel.

[0013] Since the third sealing part is connected to the second sealing part and is opposite to the first sealing part, the third sealing part cooperates with the first and second sealing parts to achieve all-round sealing of the space between the wheel arch trim, the side panel and the door panel. This can more effectively prevent rainwater, mud, dust and other external debris from entering the vehicle interior and body structure, reducing the damage and corrosion of components that may be caused by the intrusion of these debris.

[0014] In some embodiments, the snap-fit ​​component includes: a snap-fit ​​body, a snap-fit ​​space formed within the snap-fit ​​body, and a snap-fit ​​interface formed on the snap-fit ​​component communicating with the snap-fit ​​space, wherein at least a portion of the door panel passes through the snap-fit ​​interface and snaps into the snap-fit ​​component within the snap-fit ​​space.

[0015] Based on the aforementioned technical means, the design of the snap-fit ​​interface and snap-fit ​​space allows the door panel to be accurately inserted into the snap-fit ​​interface and snapped into place within the snap-fit ​​space. This facilitates installation by workers, enabling rapid assembly of the door panel and snap-fit ​​component, improving the efficiency of the sealing assembly, and reducing the incidence of poor sealing due to improper installation. Furthermore, the snap-fit ​​structure within the snap-fit ​​space provides strong connection force, making the connection between the door panel and the snap-fit ​​component more secure. Therefore, even under vibration, bumps, or other external forces during vehicle operation, the door panel is less likely to detach from the snap-fit ​​component, ensuring the overall stability of the sealing assembly and contributing to long-term reliable sealing performance.

[0016] In some embodiments, a guide lip and a snap-fit ​​lip are provided on the inner wall of the snap-fit ​​space. The walls on which the guide lip and the snap-fit ​​lip are located are arranged opposite to each other, and both the guide lip and the snap-fit ​​lip are adapted to contact the door panel.

[0017] Thus, during door panel installation, the guide lip guides the door panel, allowing it to smoothly enter the snap-fit ​​space. The guide lip guides the door panel to accurately align with the snap-fit ​​position, reducing alignment time and difficulty during installation and improving efficiency. Furthermore, the snap-fit ​​lip provides a tight snap-fit ​​after contacting the door panel, increasing friction and engagement between the snap-fit ​​component and the door panel, making the door panel more securely fixed within the snap-fit ​​space. Even when the vehicle experiences vibrations or bumps during driving, the door panel is less likely to detach from the snap-fit ​​component, ensuring the overall stability of the sealing assembly and maintaining good sealing performance. In addition, both the snap-fit ​​lip and the guide lip are in contact with the door panel, further filling the tiny gaps between the door panel and the snap-fit ​​component, preventing external dust, rainwater, noise, etc., from entering the vehicle interior through these gaps, improving the vehicle's sealing performance and creating a more comfortable and quiet driving environment for passengers.

[0018] In some embodiments, the snap-fit ​​space includes a first inner wall and a second inner wall disposed opposite to each other. The first inner wall is provided with a plurality of guide lips, and the second inner wall is provided with a plurality of snap-fit ​​lips. The contact point between any guide lip and the door panel is located between two adjacent contact points between the snap-fit ​​lips and the door panel, or, the contact point between any snap-fit ​​lip and the door panel is located between two adjacent contact points between the guide lip and the door panel.

[0019] Because multiple guide lips and snap-fit ​​lips are alternately distributed, the guide lips provide precise guidance for the door panel during installation, ensuring that the door panel accurately enters the snap-fit ​​space along the predetermined path. This reduces installation deviations and alignment difficulties, improving installation efficiency and accuracy. Furthermore, the multiple snap-fit ​​lips contact the door panel, and their contact points are staggered from those of the guide lips. This creates multiple evenly distributed snap-fit ​​positions, increasing the connection points between the snap-fit ​​components and the door panel, thereby improving the stability of the connection. Even when the vehicle is subjected to external forces such as vibration and bumps during driving, the door panel is unlikely to detach from the snap-fit ​​components.

[0020] In some embodiments, a plurality of snap-fit ​​lips extend into the snap-fit ​​space relative to the snap-fit ​​interface, and / or a plurality of guide lips extend into the snap-fit ​​space relative to the snap-fit ​​interface.

[0021] Because the snap-fit ​​lip extends into the snap-fit ​​space, it increases the contact area and snap-fit ​​depth between the snap-fit ​​lip and the door panel. This larger contact area allows for a more even distribution of snap-fit ​​force, preventing stress concentration and improving the stability of the connection between the snap-fit ​​and the door panel. This makes it more difficult for the door panel to detach from the snap-fit ​​under external forces. Furthermore, the guide lip extending into the snap-fit ​​space provides more precise and longer-distance guidance for the door panel installation. During insertion into the snap-fit ​​space, the door panel moves more smoothly along the extended guide lip, reducing deviation and jamming, lowering installation difficulty, and improving installation efficiency and accuracy.

[0022] In some embodiments, the sealing strip further includes: a bent portion connected between the first sealing portion and the second sealing portion, the bent portion being bent so that the first sealing portion and the second sealing portion are spaced apart; the snap-fit ​​member further includes: a protruding support portion connected to the snap-fit ​​body, the protruding support portion being connected to the bent portion and adapted to support the bent portion.

[0023] Because the bent portion connects the first and second sealing portions and is spaced apart from each other, when the door is closed, the different sealing portions can fit tightly against different parts of the door and body, thus better adapting to complex gap changes between the door and body, increasing the flexibility and adaptability of the seal, and improving the sealing effect. Furthermore, during the door opening and closing process, the sealing strip is subjected to stresses such as compression and tension. The bent portion can buffer these stresses through its own bending deformation, reducing damage to the sealing strip caused by stress concentration and extending its service life. The raised support portion connects to the bent portion, providing reliable support and preventing excessive deformation or collapse of the bent portion under external forces, ensuring the shape and positional stability of the bent portion, and thus ensuring the overall sealing performance of the sealing strip.

[0024] In addition, when the door is closed, the raised support can distribute the pressure of the door on the sealing strip to the bending part and the entire sealing strip, avoiding excessive local stress, making the sealing strip more evenly stressed, reducing the possibility of local wear or deformation of the sealing strip, and improving the overall durability of the sealing strip.

[0025] In some embodiments, the raised support portion and the snap-fit ​​body are an integral structure. According to the above-described technical means, when subjected to external forces such as the impact force when the door closes and vibrations during vehicle operation, the integral structure can more effectively transmit and disperse stress, preventing damage caused by localized stress concentration. The raised support portion can more reliably transmit pressure to the snap-fit ​​body, thereby enhancing the overall snap-fit ​​component's support capacity for the bent portion of the sealing strip. Furthermore, the integral structure design reduces the number of parts and assembly steps in the sealing assembly, thereby improving the production efficiency of the sealing assembly and shortening the production cycle.

[0026] Secondly, embodiments of this application also provide a vehicle that includes the sealing assembly described in the first aspect above.

[0027] Since the vehicle provided in this application includes the sealing component in the first aspect, it can solve the same technical problems as the sealing component described above and achieve the same technical effects, so it will not be described again here. Attached Figure Description

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0043] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0044] Firstly, please refer to Figure 1 , Figure 1 A schematic diagram of a sealing assembly provided in an embodiment of this application is shown. The sealing assembly 100 includes a sealing strip 10, a wheel arch trim piece 20, and a side panel 30. The sealing assembly 100 can be installed in the rear door of a vehicle, or it can be installed in the front door of a vehicle; this application does not limit the installation to either.

[0045] It should be noted that the side panel 30 is located on the side of the car body and is part of the body panel. It extends from the front to the rear of the vehicle, roughly on the outside of the door, covering the frame structure of the side of the body. Specifically, its front end connects to the front fender and A-pillar, its rear end connects to the rear fender and C-pillar, its lower end connects to the sill beam, and its upper end cooperates with components such as the roof side panel or window frame to form a complete appearance and closed structure of the vehicle side.

[0046] Wheel arch trim pieces 20 are typically installed on the fenders above the tires, surrounding the upper part of the tire. Specifically, the front wheel arch trim pieces 20 are located on the fenders above the front wheels, and the rear wheel trim pieces are located on the fenders above the rear wheels. Wheel arch trim pieces 20 protect the vehicle body from various road surface damages. During driving, tires kick up stones, mud, and other debris; wheel arch trim pieces 20 can prevent these debris from impacting and splashing onto the sides of the vehicle, reducing wear and corrosion to the paint, especially providing excellent protection for areas like the fenders, thus lowering the risk of vehicle damage. Wheel arch trim pieces 20 can also refine and complement the vehicle's lines, making them smoother and more continuous, giving the vehicle a more cohesive and harmonious visual appearance.

[0047] For example, the wheel arch trim 20 can be a rear door wheel arch trim 20 or a front door wheel arch trim 20. This application does not limit it in this regard. For ease of description, this application describes the embodiment with the sealing component 100 installed on the rear door of the vehicle as an example, that is, it describes the embodiment with the wheel arch trim 20 installed on the rear door wheel arch trim 20 as an example.

[0048] Optionally, the sealing strip 10 can be made of materials such as ethylene propylene diene monomer (EPDM) rubber foam to form a bubble tube. Because EPDM rubber has good elasticity and resistance to compression deformation, it is resistant to weathering, ozone, and chemical action, and can maintain stable performance within a wide temperature range (-40℃ to +120℃). This can improve the service life of the sealing assembly 100.

[0049] Optionally, the material of the sealing strip 10 can also be natural rubber (NR), nitrile rubber (NBR), silicone rubber (SR), chloroprene rubber (CR), etc., and this application embodiment does not limit this.

[0050] Please see Figure 1 and Figure 2 , Figure 2 This is a schematic diagram of the structure of a sealing body and a snap-fit ​​component provided in an embodiment of this application. In some embodiments of this application, the sealing strip 10 includes: a first sealing part 11 and a second sealing part 12 connected to each other. The first sealing part 11 is in contact with the outer trim piece 20 of the wheel arch, and the second sealing part 12 is in contact with the outer side panel 30. That is, the first sealing part 11 abuts against the outer trim piece 20 of the wheel arch, and the second sealing part 12 abuts against the outer side panel 30.

[0051] In one possible structural design, the second sealing part 12 is in contact with the side outer panel 30. In this way, by making the second sealing part 12 in contact with the side outer panel 30, the sealing effect between the second sealing part 12 and the side outer panel 30 can be improved, effectively enhancing the NVH quality of the vehicle. It also effectively fills the gap between the wheel arch trim 20 and the side outer panel 30, preventing external dust, rain, wind and noise from entering the vehicle, creating a quiet, comfortable and clean environment inside the vehicle.

[0052] In another possible structural design, the second sealing part 12 can also make line contact with the outer side panel 30. In this way, the line contact between the second sealing part 12 and the outer side panel 30 can concentrate the sealing pressure to a certain extent. Then, when the door is closed or subjected to external force, the second sealing part 12 will undergo elastic deformation, and the line contact part can better conform to the subtle contour changes of the surface of the outer side panel 30, thereby effectively preventing air, rainwater, dust, etc. from entering the vehicle along the contact part.

[0053] It should be noted that the contact arrangement between the first sealing part 11 and the outer trim piece 20 of the wheel arch can be surface contact or line contact. This application does not limit this, and you can refer to the above description of the contact arrangement between the second sealing part 12 and the outer side panel 30.

[0054] In addition, the edge of the wheel arch trim 20 is set higher than the side panel 30. The wheel arch trim 20 includes a first plate 21 and a second plate 22 connected to each other. The first plate 21 is located on the same side of the side panel 30 and the sealing strip 10, and the second plate 22 is located at the bottom of the sealing strip 10. The first plate 21 is in contact with the first sealing part 11. One side of the first plate 21 is connected to the second plate 22, and the end face of the other side of the first plate 21 is set higher than the side panel 30.

[0055] Since the first sealing part 11 is in contact with the outer trim piece 20 of the wheel arch and the second sealing part 12 is in contact with the outer side panel 30, it can effectively block mud and water splashed during vehicle operation and prevent them from entering the gap between the outer trim piece 20 of the wheel arch and the outer side panel 30, thereby preventing mud and water from entering the vehicle or corroding the internal structure of the vehicle body.

[0056] In addition, since the edge of the wheel arch trim 20 is set higher than the side panel 30, the edge of the wheel arch trim 20 is set higher. As a result, during vehicle operation, mud and sand on the tires will be thrown onto the outer surface of the wheel arch trim 20, thus preventing mud and sand from being thrown onto the sealing strip 10. This avoids the accumulation of mud and sand at the sealing strip 10, solving the problem of difficult cleaning of mud and sand at the sealing strip 10 during car washing, thereby improving the user experience.

[0057] In some embodiments of this application, the sealing assembly 100 further includes a snap-fit ​​member 40, which is connected to the sealing strip 10. The sealing assembly 100 also includes a door panel 50, which is snap-fitted to the snap-fit ​​member 40 and is in contact with the sealing strip 10, that is, the door panel 50 and the sealing strip 10 are in contact.

[0058] For example, the snap-fit ​​connector 40 can be made of EPDM resin. Because EPDM resin has excellent weather resistance, it can withstand long-term exposure to sunlight, rain, and other natural environments without easily aging, cracking, or hardening. This extends the service life of the snap-fit ​​connector 40, ensuring it maintains good sealing performance and effectively preventing rainwater, dust, and air penetration.

[0059] Thus, by providing the snap-fit ​​component 40, the installation of the sealing assembly 100 is made simpler. Specifically, the snap-fit ​​method allows for quick and accurate installation of the sealing strip 10 onto the door panel 50, reducing installation time and complexity, and improving production and maintenance efficiency. Furthermore, the snap-fit ​​design between the snap-fit ​​component 40 and the door panel 50, as well as the contact design between the sealing strip 10 and the door panel 50, ensures the stability of the sealing assembly 100 during vehicle operation. Therefore, under the vibration and external forces of vehicle operation, the sealing assembly 100 can reduce the risk of the sealing strip 10 loosening or falling off, ensuring the reliability of the seal.

[0060] Please continue reading. Figure 1 and Figure 2 In some embodiments, the sealing strip 10 further includes a third sealing portion 13, which is connected to the second sealing portion 12 and located on the side of the second sealing portion 12 away from the first sealing portion 11. At least a portion of the third sealing portion 13 is disposed in contact with the door panel 50.

[0061] The door panel 50 includes an inner door panel 51 and an outer door panel 52. The third sealing part 13 can be disposed in contact with the inner door panel 51, that is, the third sealing part 13 abuts against the inner door panel 51.

[0062] Optionally, the third sealing part 13 may be in surface contact with the inner door panel 51, or the third sealing part 13 may be in line contact with the inner door panel 51. This application does not limit this.

[0063] Since the third sealing part 13 is connected to the second sealing part 12 and is away from the first sealing part 11, the third sealing part 13 cooperates with the first sealing part 11 and the second sealing part 12 to achieve all-round sealing of the space between the wheel arch trim 20, the side panel 30 and the door panel 50. This can more effectively prevent rainwater, mud, dust and other external debris from entering the vehicle interior and the vehicle body structure, and reduce the damage and corrosion of components that may be caused by the intrusion of these debris.

[0064] In some embodiments, the snap-fit ​​member 40 includes: a snap-fit ​​body 40A, a snap-fit ​​space 41 formed in the snap-fit ​​body 40A, and a snap-fit ​​interface 42 formed on the snap-fit ​​member 40 communicating with the snap-fit ​​space 41, wherein the door panel 50 is at least partially inserted through the snap-fit ​​interface 42 and snap-fitted with the snap-fit ​​member 40 in the snap-fit ​​space 41.

[0065] In one possible structural design, the inner door panel 51 is connected to the outer door panel 52, and the connection between the inner door panel 51 and the outer door panel 52 is located within the snap-fit ​​space 41. Parts of the inner door panel 51 and the outer door panel 52 are respectively adapted to abut against the opposite sides of the snap-fit ​​space 41 so that the door panel 50 is snapped into the snap-fit ​​member 40 within the snap-fit ​​space 41.

[0066] For example, such as Figure 2 As shown, the outer door panel 50 includes a body and a flange structure. The edge of the inner door panel 50 is located between the body and the flange structure. The body of the outer door panel 50 abuts against one side of the snap-fit ​​space 41, and the flange structure and the inner door panel 50 abut against the other side of the snap-fit ​​space 41.

[0067] This embodiment of the application, by setting the card interface 42 and the card engagement space 41, allows the door panel 50 to be accurately inserted into the card interface 42 and engaged within the card engagement space 41. This facilitates installation by workers, enabling rapid assembly of the door panel 50 and the card engagement piece 40, thus improving the assembly efficiency of the sealing assembly 100.

[0068] Furthermore, the door panel 50 engages with the snap-fit ​​member 40 within the snap-fit ​​space 41. This snap-fit ​​structure provides strong connection force, making the connection between the door panel 50 and the snap-fit ​​member 40 more secure. Therefore, even when subjected to external forces such as vibration and bumps during vehicle operation, the door panel 50 is less likely to detach from the snap-fit ​​member 40, thus ensuring the overall stability of the sealing assembly 100 and helping to maintain long-term reliable sealing performance.

[0069] In some embodiments of this application, a guide lip 411 and a snap-fit ​​lip 412 are provided on the inner wall of the snap-fit ​​space 41. The wall surfaces containing the guide lip 411 and the snap-fit ​​lip 412 are arranged opposite to each other, and both the guide lip 411 and the snap-fit ​​lip 412 are adapted to contact the door panel 50. The contact between the guide lip 411 and the snap-fit ​​lip 412 and the door panel 50 can be surface contact, line contact, or point contact; this application does not limit this.

[0070] For example, such as Figure 1 and Figure 2 As shown, the body of the outer door panel 50 is in contact with the snap-fit ​​lip 412, and the flange structure of the outer door panel 50 and the inner door panel 50 are in contact with the guide lip 411.

[0071] Thus, during the installation of the door panel 50, the guide lip 411 guides the door panel 50, allowing it to enter the snap-fit ​​space 41 more smoothly. The guide lip 411 guides the door panel 50 to accurately align with the snap-fit ​​position, reducing alignment time and difficulty during installation and improving installation efficiency. In addition, after the snap-fit ​​lip 412 contacts the door panel 50, it provides a tight snap-fit ​​action, increasing the friction and interlocking force between the snap-fit ​​member 40 and the door panel 50, making the door panel 50 more securely fixed within the snap-fit ​​space 41. Even if the vehicle experiences vibrations, bumps, or other external forces during driving, the door panel 50 is not easily dislodged from the snap-fit ​​member 40, ensuring the stability of the overall structure of the sealing assembly 100 and thus maintaining good sealing performance. In addition, both the snap-fit ​​lip 412 and the guide lip 411 are in contact with the door panel 50, which can further fill the tiny gap between the door panel 50 and the snap-fit ​​40, preventing external dust, rain, noise and other external factors from entering the vehicle through these gaps, improving the vehicle's sealing performance, and creating a more comfortable and quiet driving environment for passengers.

[0072] In some embodiments, the snap-fit ​​space 41 includes a first inner wall and a second inner wall disposed opposite to each other. The first inner wall is provided with a plurality of guide lips 411, and the second inner wall is provided with a plurality of snap-fit ​​lips 412. The contact point between any guide lip 411 and the door panel 50 is located between two adjacent contact points between the snap-fit ​​lips 412 and the door panel 50, or, the contact point between any snap-fit ​​lip 412 and the door panel 50 is located between two adjacent contact points between the guide lips 411 and the door panel 50.

[0073] For example, such as Figure 2 As shown, the first inner wall is provided with two guide lips 411, namely the first guide lip 4111 and the second guide lip 4112, and the second inner wall is provided with three snap-fit ​​lips 412, namely the first snap-fit ​​lip 4121, the second snap-fit ​​lip 4122, and the third snap-fit ​​lip 4123. The contact points between the first guide lip 4111 and the door panel 50 are all located between the contact points between the first snap-fit ​​lip 4121 and the second snap-fit ​​lip 4122 and the door panel 50; the contact points between the second guide lip 4112 and the door panel 50 are all located between the contact points between the second snap-fit ​​lip 4122 and the third snap-fit ​​lip 4123 and the door panel 50. In this way, by using three snap-fit ​​lips 412 and two guide lips 411 to position the door panel 50, the position of the door panel 50 can be effectively prevented from flipping after assembly, which would lead to problems such as the door panel 50 not being securely fixed and poor sealing.

[0074] Because multiple guide lips 411 and snap-fit ​​lips 412 are alternately distributed, the guide lips 411 can provide precise guidance for the door panel 50 during installation, ensuring that the door panel 50 accurately enters the snap-fit ​​space 41 along the predetermined path, reducing deviations and alignment difficulties during installation, and improving installation efficiency and accuracy.

[0075] Furthermore, multiple snap-fit ​​lips 412 contact the door panel 50, and their contact points are staggered from the contact points of the guide lips 411. This creates multiple evenly distributed snap-fit ​​positions, increasing the connection points between the snap-fit ​​member 40 and the door panel 50, thereby improving the stability of the connection. Even if the vehicle is subjected to external forces such as vibration or bumps during driving, the door panel 50 is unlikely to detach from the snap-fit ​​member 40.

[0076] In some other embodiments of this application, a guide lip 411 and a snap-fit ​​lip 412 are provided on the inner wall of the snap-fit ​​space 41. The contact points of the snap-fit ​​lip 412 and the door panel 50, and the contact points of the guide lip 411 and the door panel 50, are located on opposite sides of the door panel 50. Thus, the snap-fit ​​lip 412 and the guide lip 411 act from both sides of the door panel 50, forming a bidirectional fixing method. The snap-fit ​​lip 412 provides snap-fit ​​force to firmly fix the door panel 50 within the snap-fit ​​space 41, while the guide lip 411, after installation, also provides a certain degree of limiting and auxiliary fixing effect on the door panel 50, enhancing the connection strength between the door panel 50 and the snap-fit ​​member 40. Therefore, during vehicle operation, the door panel 50 is more difficult to detach from the snap-fit ​​space 41 when facing external forces such as vibration and bumps.

[0077] In one possible structural design, multiple snap-fit ​​lips 412 extend into the snap-fit ​​space 41 relative to the snap-fit ​​interface 42, and / or multiple guide lips 411 extend into the snap-fit ​​space 41 relative to the snap-fit ​​interface 42.

[0078] Because the snap-fit ​​lip 412 extends into the snap-fit ​​space 41, the contact area and snap-fit ​​depth between the snap-fit ​​lip 412 and the door panel 50 are increased. The larger contact area allows for a more even distribution of snap-fit ​​force, avoiding stress concentration and improving the stability of the connection between the snap-fit ​​member 40 and the door panel 50, making it more difficult for the door panel 50 to detach from the snap-fit ​​member 40 under external force. The guide lip 411 extending into the snap-fit ​​space 41 provides more precise and longer-distance guidance for the installation of the door panel 50. During insertion into the snap-fit ​​space 41, the door panel 50 can move more smoothly along the extended guide lip 411, reducing deviation and jamming, lowering installation difficulty, and improving installation efficiency and accuracy. In another possible structural design, multiple snap-fit ​​lips 412 extend into the snap-fit ​​interface 42, and / or multiple guide lips 411 extend into the snap-fit ​​interface 42; this application does not limit this to a specific design.

[0079] In some embodiments, the sealing strip 10 further includes a bent portion 14 connected between the first sealing portion 11 and the second sealing portion 12, the bent portion 14 being bent so that the first sealing portion 11 and the second sealing portion 12 are spaced apart; the snap-fit ​​member 40 further includes a protruding support portion 40B connected to the snap-fit ​​body 40A, the protruding support portion 40B being connected to the bent portion 14 and adapted to support the bent portion 14.

[0080] Since the bent portion 14 connects the first sealing portion 11 and the second sealing portion 12 and they are spaced apart, when the door is closed, the different sealing portions can fit tightly against different parts of the door and the body, thereby better adapting to the complex gap changes between the door and the body, increasing the flexibility and adaptability of the sealing, and thus improving the sealing effect.

[0081] Furthermore, during the opening and closing of the car door, the sealing strip 10 is subjected to stresses such as compression and tension. The bending portion 14 can buffer these stresses through its own bending deformation, reducing damage to the sealing strip 10 caused by stress concentration and extending its service life. The protruding support portion 40B is connected to the bending portion 14, thereby providing reliable support for the bending portion 14, preventing excessive deformation or collapse of the bending portion 14 under external force, ensuring the shape and positional stability of the bending portion 14, and thus ensuring the sealing performance of the entire sealing strip 10.

[0082] In addition, when the door is closed, the raised support 40B can distribute the pressure of the door on the sealing strip 10 to the bending part 14 and the entire sealing strip 10, avoiding excessive local stress, making the sealing strip 10 more evenly stressed, reducing the possibility of local wear or deformation of the sealing strip 10, and improving the overall durability of the sealing strip 10.

[0083] In some embodiments, the raised support portion 40B and the snap-fit ​​body 40A are integrally formed. Because the raised support portion 40B and the snap-fit ​​body 40A are integrally formed, the integral structure can more effectively transmit and disperse stress when subjected to external forces such as the impact force when the door closes and vibrations during vehicle operation, preventing damage caused by localized stress concentration. The raised support portion 40B can more reliably transmit pressure to the snap-fit ​​body 40A, thereby enhancing the overall support capacity of the snap-fit ​​member 40 for the bent portion 14 of the sealing strip 10. Furthermore, the integral structure design reduces the number of parts and assembly steps of the sealing assembly 100, thereby improving the production efficiency of the sealing assembly 100 and shortening the production cycle.

[0084] Furthermore, compared to the steel strip set inside the snap-fit ​​body 40A in related technologies, the snap-fit ​​body 40A of this application embodiment is lighter in weight, which is beneficial to the lightweight design of the sealing assembly 100, thereby achieving the purpose of weight reduction and cost reduction.

[0085] Secondly, embodiments of this application also provide a vehicle, including a sealing assembly 100. The sealing assembly 100 can be referred to in the description of the first aspect above, and will not be repeated here.

[0086] Since the first sealing part 11 is in contact with the outer trim piece 20 of the wheel arch and the second sealing part 12 is in contact with the outer side panel 30, it can effectively block mud and water splashed during vehicle operation and prevent them from entering the gap between the outer trim piece 20 of the wheel arch and the outer side panel 30, thereby preventing mud and water from entering the vehicle or corroding the internal structure of the vehicle body.

[0087] In addition, since the edge of the wheel arch trim 20 is set higher than the side panel 30, the edge of the wheel arch trim 20 is set higher. As a result, during vehicle operation, mud and sand on the tires will be thrown onto the outer surface of the wheel arch trim 20, thus preventing mud and sand from being thrown onto the sealing strip 10. This avoids the accumulation of mud and sand at the sealing strip 10, solving the problem of difficult cleaning of mud and sand at the sealing strip 10 during car washing, thereby improving the user experience.
