Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle sealing technology, and in particular to a sealing strip and a vehicle. Background Technology
[0002] At the wheel arch area, a sealing strip needs to be installed between the door and the side panel to ensure the sealing performance after the door is closed and to prevent mud and sand thrown out by the wheels from entering the vehicle.
[0003] However, during vehicle use, mud and sand thrown out by the wheels inevitably enter the area between the sealing strip and the rounded corner of the side panel, and adhere to the sealing strip. If the mud and sand are not cleaned in time, they may wear down the paint of the side panel as the vehicle is driven, which is not conducive to maintaining the appearance quality of the vehicle. Utility Model Content
[0004] In view of this, this application aims to provide a sealing strip to help maintain the appearance quality of a vehicle.
[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:
[0006] A sealing strip includes a mounting portion that can be installed on a vehicle door, and a sealing portion connected to the mounting portion;
[0007] The sealing portion has a first lip extending outward to one side of itself;
[0008] When the door is closed, the sealing part can seal the gap between the door and the side panel, the first lip can cover the edge of the side panel, and the first lip is spaced apart from the edge of the side panel.
[0009] Furthermore, the sealing portion includes a sealing portion body having a first chamber, the first chamber extending along the extending direction of the sealing portion body;
[0010] With the door closed, the main body of the sealing part abuts against the side panel sheet metal.
[0011] Furthermore, the first chamber is provided with a support body, which divides the first chamber into a first sub-chamber and a second sub-chamber located on both sides of the support body;
[0012] The first sub-chamber is located on the side of the support body facing the side panel sheet metal, and the second sub-chamber is located on the side of the support body facing the vehicle door.
[0013] Furthermore, the sealing part body has a first sidewall and a second sidewall located on two opposite sides of the first chamber, one end of the first sidewall and the second sidewall are connected together, and the other end is connected through a third sidewall;
[0014] A portion of the first sidewall protrudes toward the side where the side panel sheet metal is located and is able to abut against the side panel sheet metal. The angle between the portion of the protruding part away from the first lip and the side panel sheet metal is between 45° and 60°.
[0015] Furthermore, a second groove is provided on the side of the first sidewall facing the first compartment, and the second groove is recessed into the interior of the first sidewall itself.
[0016] Furthermore, a third groove is provided on the side of the third sidewall facing the first sub-chamber, and the third groove is recessed into the interior of the third sidewall itself.
[0017] Furthermore, in the left-right direction of the vehicle, the mounting part is connected to the middle of the sealing part body, and the support body is located in the middle of the first cavity.
[0018] Furthermore, the sealing part body is provided with a second lip extending outward to one side, and both the first lip and the second lip are provided on the side of the sealing part body facing outward from the gap;
[0019] The second lip extends in the opposite direction to the first lip and is able to abut against the car door.
[0020] Furthermore, the sealing part has a first groove on the side facing outward from the gap, and the first groove is recessed into the sealing part itself.
[0021] Furthermore, the mounting part is provided with a buckle, which can be snapped into the door to install the sealing strip on the door.
[0022] Compared with related technologies, this application has the following advantages:
[0023] (1) The sealing strip described in this application can be installed on the car door through the mounting part. The sealing part can seal the gap between the car door and the side panel to isolate the inside and outside environment of the car door. The first lip can prevent external mud and sand from entering the side panel and contacting the sealing part during vehicle operation, which is not easy to cause mud and sand accumulation. This is beneficial to improving the sealing performance of the sealing strip. In addition, during winter use, the inner side of the rounded corner of the side panel will not be affected by the accumulated mud and sand and freeze, which is beneficial to improving the user's driving experience. At the same time, the first lip and the edge of the side panel are arranged at intervals so that the mud and sand adhering to the surface of the first lip will not rub against the edge of the side panel, thereby reducing the wear of the side panel paint and helping to maintain the appearance quality of the vehicle.
[0024] (2) A sealing part body is provided, and a first chamber extending along the sealing part body is provided in the sealing part body, so that the sealing part body is hollow and can quickly deform to press against the side sheet metal when squeezed by the car door and side sheet metal, and adapt to the fine tolerance of the side sheet metal surface, so that the sealing pressure is evenly distributed, avoiding local air leakage or water leakage, and having a better sealing effect.
[0025] (3) A support body is set in the first chamber. The support body can support the main body of the sealing part from the inside, so that the main body of the sealing part is not prone to local deformation and collapse in the direction of the gap, thus forming a wave-shaped defect. The first sub-chamber and the second sub-chamber are arranged in sequence between the side panel sheet metal and the door. The two sub-chambers can work together. When the door is closed, they can absorb more impact through elastic deformation. They are not prone to failure due to repeated compression of the door opening and closing, which is conducive to extending the service life.
[0026] (4) The first sidewall, the second sidewall and the third sidewall are provided on the main body of the sealing part, which can form a closed tubular structure. The first sidewall is protruding, which is conducive to pressing the main body of the sealing part tightly against the side sheet metal. The part of the protruding part of the first sidewall away from the first lip is set at an angle of 45°-60° with the side sheet metal. Under different closing forces, the first sidewall can easily deform and press against the side sheet metal.
[0027] (5) A second groove is provided on the side of the first sidewall facing the first chamber, which allows the sealing part body to be guided by the second groove to deform into the second groove when it is squeezed by the side sheet metal. The first sidewall bends at a fixed point, so that when the first sidewall is pressed against the side sheet metal, the first lip does not contact the edge of the side sheet metal. At the same time, the deformation at the second groove can disperse the compressive stress on the first sidewall, avoid local cracking, extend service life, and reduce the weight of the sealing strip and reduce costs.
[0028] (6) A third groove is provided on the side of the third sidewall facing the first sub-chamber, which allows the sealing part body to be guided by the third groove when it is squeezed by the side wall sheet metal, causing the third sidewall to expand and deform along the third groove. The third sidewall bends outward at a fixed point, so that when the first sidewall is pressed against the side wall sheet metal, the first lip does not contact the edge of the side wall sheet metal. At the same time, the deformation at the third groove can disperse the compressive stress on the third sidewall, avoid local cracking, extend service life, and reduce the weight of the sealing strip, thus reducing costs.
[0029] (7) The mounting part is connected to the middle of the sealing part body, and the support body is placed in the middle of the first chamber. The mounting part can support the support body, thereby improving the support effect of the support body on the sealing part body, optimizing the force transmission path inside the sealing strip, and enhancing the overall strength of the sealing strip.
[0030] (8) Setting a second lip to press against the door can better seal the gap between the sealing body and the door, preventing mud and sand thrown out by the wheels from entering the area between the door and the sealing body, thereby further improving the sealing ability of the sealing strip. At the same time, it can also cover the sheet metal connection at the edge of the door, enhancing the perception of a refined appearance.
[0031] (9) The first groove is recessed into the sealing part, which allows the mud and sand thrown out by the tire to bounce towards the center of the first groove after hitting the groove wall, thereby reducing the mud and sand entering between the sealing part and the side sheet metal. At the same time, it makes the sealing part more easily deformed when compressed, and when the sealing part deforms, the deformation direction of the first lip is away from the edge of the side sheet metal, so the first lip is less likely to rub against the edge of the side sheet metal. A buckle is provided on the mounting part, and the sealing strip can be quickly installed on the door through the buckle. The operation is simple and efficient, and the sealing strip connection is reliable.
[0032] This application also proposes a vehicle equipped with the aforementioned sealing strip.
[0033] The vehicle described in this application, by setting the aforementioned sealing strip, can isolate the interior and exterior environments of the vehicle door. The first lip can prevent external mud and sand from entering the side panel sheet metal and pressing the sealing part during vehicle operation, making it less prone to mud and sand accumulation, which is beneficial to improving the sealing performance of the sealing strip. In addition, during winter use, the edge of the side panel sheet metal will not be affected by accumulated mud and freeze, which is beneficial to improving the user's driving experience. At the same time, the first lip is spaced apart from the edge of the side panel sheet metal, which prevents mud and sand adhering to the surface of the first lip from rubbing against the edge of the side panel sheet metal, thereby reducing wear on the paint surface of the side panel sheet metal and helping to maintain the appearance quality of the vehicle.

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.
[0048] 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.
[0049] An embodiment of the first aspect of this application provides a sealing strip applied between the door and side panel sheet metal at the wheel arch of a vehicle to reduce the wear on the paint surface of the side panel sheet metal caused by dirt and sand adhering to the sealing strip, thereby helping to maintain the appearance quality of the vehicle.
[0050] In related technologies, a sealing strip needs to be installed at the wheel arch, between the door and the side panel, to ensure the sealing performance after the door is closed and to prevent mud and sand thrown out by the wheels from entering the vehicle.
[0051] However, during vehicle use, mud and sand thrown out by the wheels inevitably enter the area between the sealing strip and the rounded corner of the side panel, and adhere to the sealing strip. If the mud and sand are not cleaned in time, they may wear down the paint of the side panel as the vehicle is driven, which is not conducive to maintaining the appearance quality of the vehicle.
[0052] In view of this, in order to overcome the shortcomings of related technologies, the sealing strip in this embodiment combines... Figure 1 In terms of overall design, it includes a mounting part 1 that can be installed on the door 3, and a sealing part 2 connected to the mounting part 1.
[0053] The sealing part 2 has a first lip 201 extending outward to one side. When the door 3 is closed, the sealing part 2 can seal the gap between the door 3 and the side panel 4, and the first lip 201 can cover the edge of the side panel 4, and the first lip 201 is spaced apart from the edge of the side panel 4.
[0054] Therefore, by setting the mounting part 1, the sealing strip can be installed on the door 3, and the sealing part 2 can seal the gap between the door 3 and the side panel 4, thus isolating the door 3 from the internal and external environments. The first lip 201 prevents external mud and sand from entering the side panel 4 and compressing the sealing part 2 during vehicle operation, reducing mud and sand accumulation and improving the sealing performance of the sealing strip. Furthermore, during winter use, the inner corners of the rounded edges of the side panel 4 will not freeze due to accumulated mud and sand, improving the user experience. Simultaneously, the spacing between the first lip 201 and the edge of the side panel 4 prevents mud and sand adhering to the surface of the first lip 201 from rubbing against the edge of the side panel 4, reducing wear on the paint surface of the side panel 4 and maintaining the vehicle's appearance quality.
[0055] Based on the above overview, please refer to... Figure 1 As shown, specifically, the sealing strip in this embodiment can be made of rubber. Because the sealing strip is located at the wheel arch, if mud or sand adheres to the tires during vehicle operation, this mud and sand will inevitably be flung out with the tire rotation, directly or indirectly adhering to the sealing strip. Due to the tight fit between the sealing strip and the side panel 4, the sealing strip may rub against the side panel 4 when the door 3 is opened and closed, and the mud and sand between the sealing strip and the side panel 4 will exacerbate the wear on the side panel 4. Secondly, if mud and sand accumulate between the sealing strip and the side panel 4, and the mud and sand easily contain moisture, it may cause freezing between the sealing strip and the side panel 4 during winter use, potentially damaging the paint if the door is forcibly opened.
[0056] In this embodiment, the sealing strip has a first lip 201 that extends outward, which can block mud and sand in the direction in which they are thrown out, greatly reducing the amount of mud and sand that enters the contact area between the side panel 4 and the sealing part 2. Mud and sand are less likely to accumulate there, which helps to reduce the wear of mud and sand on the side panel 4 and also greatly reduces the possibility of freezing between the sealing strip and the side panel 4 when using the vehicle in winter.
[0057] It should be noted that the side panel 4 is bent at the edges to form rounded corners. When the door 3 is closed, if the first lip 201 wraps around the rounded corners of the side panel 4, it can reduce the amount of mud and sand entering the contact area between the side panel 4 and the sealing part 2. However, due to the daily opening and closing of the door 3 or other factors, mud and sand will inevitably stick to the side of the side panel 4 where the first lip 201 wraps around the rounded corners. Misalignment of the first lip 201 relative to the side panel 4 may cause wear and tear on the rounded corners of the side panel 4 caused by mud and sand.
[0058] In this embodiment, the first lip 201 and the rounded corner of the side sheet metal 4 are spaced apart, and no friction occurs between the first lip 201 and the rounded corner of the side sheet metal 4, which can effectively maintain the integrity of the paint surface at the rounded corner of the side sheet metal 4, thereby helping to maintain the appearance quality of the vehicle.
[0059] Preferably, when designing the first lip 201, the edge of the first lip 201 needs to extend beyond the rounded corner of the side panel 4 to maximize the area for blocking mud and sand. The distance between the first lip 201 and the rounded corner of the side panel edge should be at least 0.7mm to minimize the possibility of friction between the first lip 201 and the side panel 4.
[0060] Continue to combine Figure 1 As shown, in some exemplary embodiments, the sealing portion 2 includes a sealing portion body 202 having a first chamber 2021 extending along the extending direction of the sealing portion body 202. When the door 3 is closed, the sealing portion body 202 abuts against the side panel 4. At the vehicle wheel arch, the sealing portion body 202 is arranged conformally along the edges of the side panel 4 and the door 3, so that when the door 3 is closed, it can press the sealing portion body 202 against the side panel 4, achieving interference sealing between the sealing strip and the side panel 4.
[0061] This design, with a first chamber 2021 extending along the sealing body 202 within the sealing body 202, allows the sealing body 202 to be a hollow tube. When compressed by the door 3 and the side panel 4, it can quickly deform to press against the side panel 4, adapting to the minute tolerances on the surface of the side panel 4, ensuring even distribution of sealing pressure, preventing localized air or water leakage, and achieving a better sealing effect. Simultaneously, the sealing body 202 can achieve dynamic sealing with the side panel 4 through elastic deformation, reducing vibration transmission, lowering door closing noise, and improving the vehicle's NVH (Noise, Vibration, Harshness) performance. The interference between the sealing body 202 and the side panel 4 ranges from 0.5mm to 1.5mm.
[0062] Understandably, the sealing body 202 can also be set as a solid structure and arranged along the edge of the side panel 4 and the door 3. However, the elastic deformation capacity of the solid sealing body 202 is not as good as that of the sealing body 202 with the first chamber 2021, and the tightness of its fit with the side panel 4 is also poor.
[0063] The sealing body 202 has a first chamber 2021. In some exemplary embodiments, the first chamber 2021 has a support 203, which divides the first chamber 2021 into a first sub-chamber 20211 and a second sub-chamber 20212 located on both sides of the support 203. The first sub-chamber 20211 is located on the side of the support 203 facing the side panel 4, and the second sub-chamber 20212 is located on the side of the support 203 facing the door 3.
[0064] In practical implementation, conventional bubble-tube type sealing strips, after prolonged use, will exhibit uneven, wavy defects along their length on the sealing side, severely affecting the sealing performance. However, by installing a support 203 in the first chamber 2021, the support 203 can internally support the sealing body 202, preventing localized deformation and collapse of the sealing body 202 in the direction inside and outside the gap, thereby improving sealing stability.
[0065] In addition, the first sub-chamber 20211 and the second sub-chamber 20212 are arranged sequentially between the side panel 4 and the door 3. The two sub-chambers can work together to absorb more impact through elastic deformation when the door 3 is closed, and are not easily damaged by repeated compression due to the opening and closing of the door 3, which helps to extend the service life.
[0066] Based on the division of the first chamber 2021 into a first sub-chamber 20211 and a second sub-chamber 20212, in some exemplary embodiments, the sealing body 202 has a first sidewall 2022 and a second sidewall 2023 located on two opposite sides of the first chamber 2021. One end of the first sidewall 2022 and the second sidewall 2023 are connected together, and the other end is connected through a third sidewall 2024. A portion of the first sidewall 2022 protrudes toward the side where the side panel 4 is provided and can abut against the side panel 4. The included angle A between the portion of the protruding part away from the first lip 201 and the side panel 4 is between 45° and 60°.
[0067] With this arrangement, the first sidewall 2022, the second sidewall 2023, and the third sidewall 2024 are provided on the sealing body 202, which can form a closed tubular structure. The protruding first sidewall 2022 is conducive to pressing the sealing body 202 tightly against the side sheet metal 4. The part of the protruding first sidewall 2022 away from the first lip 201 is set at an angle of 45°-60° with the side sheet metal 4. Under different closing forces, the first sidewall 2022 can easily deform and press against the side sheet metal 4.
[0068] Preferably, the sealing body 202 can be formed by connecting the first side wall 2022, the second side wall 2023, and the third side wall 2024 end to end to form the internal first chamber 2021. The first side wall 2022 and the second side wall 2023 are connected in the middle of the sealing body 202 in the left-right direction of the vehicle, while the third side wall 2024 faces outward from the gap between the door 3 and the side panel 4, directly bearing the impact of mud and sand thrown out by the tire, and playing a role in blocking the mud and sand.
[0069] It should be noted that, as Figure 1 As shown, the so-called outer direction of the gap between the door 3 and the side panel 4 is the direction towards the outside of the car after the door 3 is closed. Correspondingly, the direction towards the inside of the gap is the inner direction of the gap.
[0070] For ease of understanding, the first sidewall 2022 can be divided into a support section 20221, a contact section 20222, and a connecting section 20223 along the direction towards the first lip 201. The support section 20221 connects to the second sidewall 2023, has a relatively straight cross-section, and forms an angle A with the sidewall sheet metal 4, with the angle A ranging from 45° to 60°. The contact section 20222 connects to the support section 20221, has an arc-shaped convex cross-section, and abuts against the sidewall sheet metal 4, serving a sealing function. The connecting section 20223 connects the contact section 20222 and the third sidewall 2024, mainly used to transfer stress to the third sidewall 2024 after the contact section 20222 is compressed by the sidewall sheet metal 4.
[0071] Based on the sealing body 202 including a first sidewall 2022, a second sidewall 2023 and a third sidewall 2024, in some exemplary embodiments, a second groove 204 is provided on the side of the first sidewall 2022 facing the first sub-chamber 20211, and the second groove 204 is recessed into the first sidewall 2022 itself.
[0072] Thus, by providing a second groove 204 on the side of the first sidewall 2022 facing the first chamber 20211, the sealing body 202 is guided by the second groove 204 to deform the first sidewall 2022 into the second groove 204 when it is squeezed by the side sheet metal 4. The first sidewall 2022 bends at a fixed point, so that when the first sidewall 2022 is pressed against the side sheet metal 4, the first lip 201 does not contact the edge of the side sheet metal 4. At the same time, the deformation at the second groove 204 can disperse the compressive stress on the first sidewall 2022, avoid local cracking, extend service life, and reduce the weight of the sealing strip, thereby reducing costs.
[0073] Preferably, the shape of the second groove 204 can be, for example, a semi-circular cross-section groove, and the transition between the second groove 204 and the first sidewall 2022 is smoothly rounded. Of course, other shapes such as a rectangular second groove 204 can also be used, but the mechanical properties are not as good as those of the semi-circular cross-section second groove 204, and it is more prone to tearing under stress.
[0074] In specific implementation, the number and position of the second groove 204 can be selected according to the actual situation to guide the first side wall 2022 to deform in a predetermined direction when squeezed by the side sheet metal 4, so as to prevent the first lip 201 from rubbing against the edge rounded corner of the side sheet metal 4.
[0075] For example, two second grooves 204 can be provided, one inside the support section 20221 of the first sidewall 2022, and the other at the location where the connecting section 20223 of the first sidewall 2022 connects to the third sidewall 2024. After the contact section 20222 is squeezed by the sidewall sheet metal 4, the curvature of the overall cross section will decrease, and the first sidewall 2022 will be guided to deform into the two second grooves 204. That is, the opening of the second groove 204 will decrease due to the deformation of the first sidewall 2022. In this way, the first lip 201 is less likely to be pulled towards the edge rounded corner of the sidewall sheet metal 4 by the first sidewall 2022, ensuring that the first lip 201 does not rub against the edge rounded corner of the sidewall sheet metal 4.
[0076] In addition, based on the sealing body 202 including the first sidewall 2022, the second sidewall 2023 and the third sidewall 2024, the third sidewall 2024 is provided with a third groove 205 on the side facing the first sub-chamber 20211, and the third groove 205 is recessed into the third sidewall 2024 itself.
[0077] Thus, the third groove 205 provided on the side of the third sidewall 2024 facing the first chamber 20211 allows the sealing body 202 to be guided by the third groove 205 when it is squeezed by the side panel 4, causing the third sidewall 2024 to expand and deform along the third groove 205. The third sidewall 2024 bends outward at a fixed point, so that when the first sidewall 2022 presses against the side panel 4, the first lip 201 does not contact the edge of the side panel 4. At the same time, the deformation at the third groove 205 can disperse the compressive stress on the third sidewall 2024, avoid local cracking, extend service life, and reduce the weight of the sealing strip, thus reducing costs.
[0078] It is worth noting that when the third sidewall 2024 is deformed under stress, the deformation mode of the third groove 205 is different from that of the second groove 204 when the first sidewall 2022 is deformed under stress. When the first sidewall 2022 is squeezed by the side sheet metal 4, it applies a force in the direction of the gap to the third sidewall 2024. The third groove 205 will gradually open, causing the first lip 201 to move away from the edge rounded corner of the side sheet metal 4, so that the first lip 201 is less likely to rub against the edge rounded corner of the side sheet metal 4.
[0079] Preferably, the shape of the third groove 205 can be, for example, a semi-circular cross-section groove, and the transition between the third groove 205 and the third sidewall 2024 is rounded. Of course, other shapes such as a rectangular third groove 205 can also be used, but the mechanical properties are not as good as those of the semi-circular cross-section third groove 205, and it is more prone to tearing under stress.
[0080] For example, a third groove 205 can be formed on the third sidewall 2024 near the support 203. This arrangement allows the bending point of the third sidewall 2024 to be closer to the support 203 when under stress, and correspondingly, the third sidewall 2024 has a stronger ability to adapt to the deformation of the first sidewall 2022.
[0081] Based on the provision of a support 203 within the first chamber 2021, in some exemplary embodiments, the mounting portion 1 is connected to the middle of the sealing body 202 in the left-right direction of the vehicle, and the support 203 is located in the middle of the first chamber 2021. Connecting the mounting portion 1 to the middle of the sealing body 202 and simultaneously placing the support 203 in the middle of the first chamber 2021 allows the mounting portion 1 to support the support 203, thereby improving the support effect of the support 203 on the sealing body 202, optimizing the force transmission path within the sealing strip, and enhancing the overall strength of the sealing strip.
[0082] Continuing with the sealing body 202, which includes a first sidewall 2022, a second sidewall 2023, and a third sidewall 2024, the support body 203 can be fixedly connected to both the first and second sidewalls 2022 and 2023 on one side, and to the middle of the third sidewall 2024 on the other side. The mounting part 1, the support body 203, and the third sidewall 2024 form a linear force-transmitting arrangement, enabling the mounting part 1 to support the support body 203, thus allowing the support body 203 to better support the third sidewall 2024 and preventing it from collapsing or deforming. When the sealing strip is made of rubber, the support body 203 can be integrally formed with the first sidewall 2022, the second sidewall 2023, and the third sidewall 2024, resulting in better structural strength.
[0083] Based on the sealing part 2 including a sealing part body 202 with a first chamber 2021, in some exemplary embodiments, the sealing part body 202 is provided with a second lip 206 extending outward to one side. Both the first lip 201 and the second lip 206 are located on the side of the sealing part body 202 facing outward from the gap. The second lip 206 and the first lip 201 extend in opposite directions and can abut against the door 3. The second lip 206 abutting against the door 3 can better seal the gap between the sealing part body 202 and the door 3, preventing mud and sand thrown out by the wheels from entering the area between the door 3 and the sealing part body 202, thereby further improving the sealing ability of the sealing strip. At the same time, it can also cover the sheet metal connection at the edge of the door 3, improving the perceived refinement of the appearance.
[0084] Specifically, the third sidewall 2024 can be extended in the left-right direction of the vehicle, forming a first lip 201 on the side facing the side panel 4 and a second lip 206 on the side facing the door 3. The first lip 201, the third sidewall 2024 and the second lip 206 together form a barrier to prevent mud and sand from entering between the door 3 and the side panel 4.
[0085] To further reduce the possibility of mud and sand entering the gap between the door 3 and the side panel 4, in some exemplary embodiments, the sealing part 2 is provided with a first groove 207 on the side facing outward from the gap, and the first groove 207 is recessed inward from the sealing part 2 itself. The recess of the first groove 207 inward from the sealing part 2 allows mud and sand thrown out by the tire to bounce towards the center of the first groove 207 after impacting the groove wall, thereby reducing the amount of mud and sand entering between the sealing part 2 and the side panel 4. At the same time, it makes the sealing part 2 more easily deformable when compressed, and when the sealing part 2 deforms, the deformation direction of the first lip 201 is away from the edge of the side panel 4, and the first lip 201 is less likely to rub against the edge of the side panel 4.
[0086] Furthermore, regarding the specific connection method between the mounting part 1 and the door 3, in some exemplary embodiments, a clip 101 can be provided on the mounting part 1. The clip 101 can be snapped onto the door 3 to install the sealing strip on the door 3. By providing the clip 101 on the mounting part 1, the sealing strip can be quickly installed on the door 3, which is simple and efficient, and the connection of the sealing strip is reliable.
[0087] Preferably, a second chamber 102 can be provided inside the mounting part 1. The inner wall of the second chamber 102 has a through hole that extends outward through the mounting part 1. The snap-fit end of the buckle 101 passes through the through hole and snaps into the door 3. The door 3 usually adopts a structure in which the inner panel and the outer panel of the door 3 are connected. The buckle 101 can be directly snapped onto the inner panel of the door 3, thus hiding the buckle 101 in the mounting part 1 and the door 3, improving the appearance and refinement.
[0088] Meanwhile, two third lips 103 can be provided on both sides of the buckle 101 on the mounting part 1. When the sealing strip is installed on the inner panel of the door 3, the two third lips 103 can abut against the inner panel of the door 3. After the buckle 101 is installed on the inner panel of the door 3, the gap between the mounting part 1 and the inner panel of the door 3 is sealed and blocked by the third lips 103, preventing debris from entering between the inner panel of the door 3 and the outer panel of the door 3.
[0089] 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... Figure 1 As shown, it may include, for example, a mounting part 1 and a sealing part 2.
[0090] The sealing part 2 includes a sealing part body 202, which includes a first side wall 2022, a second side wall 2023 and a third side wall 2024 that are connected end to end. The third side wall 2024 faces outward from the gap between the door 3 and the side panel 4.
[0091] The third sidewall 2024 extends outward from one side to form a first lip 201, and extends outward from the other side to form a second lip 206. The first lip 201 can cover the edge of the side panel 4 and is spaced apart from the edge of the side panel 4. The second lip 206 abuts against the door 3.
[0092] The support 203 is connected to the third side wall 2024 on one side and to the junction of the first side wall 2022 and the second side wall 2023 on the other side, and divides the first chamber 2021 into the first sub-chamber 20211 and the second sub-chamber 20212.
[0093] The first sidewall 2022 has a portion that protrudes toward the side where the side panel 4 is located and can abut against the side panel 4. The angle between the part of the protruding portion away from the first lip 201 and the side panel 4 is 59°.
[0094] The first sidewall 2022 has two second grooves 204 on the side facing the first chamber 20211, and the second grooves 204 are recessed into the first sidewall 2022 itself. One of the two second grooves 204 is inside the support section 20221 of the first sidewall 2022, and the other is located at the position where the connecting section 20223 of the first sidewall 2022 connects to the third sidewall 2024.
[0095] The third sidewall 2024 has a third groove 205 on the side facing the first chamber 20211, and the third groove 205 is recessed into the third sidewall 2024 itself.
[0096] The sealing part 2 has a first groove 207 on the side facing outward from the gap, and the first groove 207 is recessed into the sealing part 2 itself.
[0097] The mounting part 1 is provided with a buckle 101, which can be snapped into the door 3 to install the sealing strip on the door 3.
[0098] In the preferred embodiment of the sealing strip above, the specific setting and arrangement of the mounting part 1, sealing part 2, 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 mounting part 1 and sealing part 2, etc., can also be referred to the description in the above exemplary embodiments.
[0099] The sealing strip in this embodiment adopts the above design. It can be installed on the door 3 by setting the mounting part 1. The sealing part 2 can seal the gap between the door 3 and the side panel 4 to isolate the interior and exterior environments of the door 3. The first lip 201 can prevent external mud and sand from entering the side panel 4 and pressing the sealing part 2 during vehicle operation, which makes it less likely for mud and sand to accumulate. This helps to improve the sealing performance of the sealing strip. In addition, the edge of the side panel 4 will not freeze due to the accumulation of mud during winter use, which helps to improve the user's driving experience.
[0100] Secondly, by arranging the first lip edge 201 and the edge of the side panel 4 at intervals, the mud and sand adhering to the surface of the first lip edge 201 will not rub against the edge of the side panel 4, thereby reducing the wear on the paint surface of the side panel 4 and helping to maintain the appearance quality of the vehicle.
[0101] An embodiment of the second aspect of this application provides a vehicle equipped with a sealing strip as described in the first aspect embodiment. Specifically, the sealing strip can be applied to the rear wheel arches of the vehicle.
[0102] In this embodiment, the vehicle, by setting the sealing strip of the first aspect embodiment, can isolate the internal and external environments of the door 3, thereby improving the vehicle's NVH (Noise, Vibration, Harshness) performance. The first lip 201 prevents external mud and sand from entering the side panel 4 and compressing the sealing part 2 during vehicle operation, reducing the accumulation of mud and sand and improving the sealing performance of the sealing strip. Furthermore, during winter use, the flange of the side panel 4 will not freeze due to accumulated mud, thus improving the user's driving experience.
[0103] Secondly, by arranging the first lip edge 201 and the edge of the side panel 4 at intervals, the mud and sand adhering to the surface of the first lip edge 201 will not rub against the edge of the side panel 4, thereby reducing the wear on the paint surface of the side panel 4 and helping to maintain the appearance quality of the vehicle.
