Description

Technical Field

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

[0002] In vehicles, to prevent water or dust from entering the doors and to reduce noise while the vehicle is in motion, sealing strips are usually installed for sealing. In related technologies, the sealing strips at the vehicle door position are generally designed with a bubble tube structure, and the required sealing effect is achieved by the abutment between the bubble tube structure and the door or body side panel.

[0003] However, due to limitations in materials and structure, current sealing strips used for sealing car doors still suffer from insufficient sealing power, especially noticeable in frameless vehicles where there are no window frames on the doors. Insufficient sealing power can easily lead to problems such as water leakage and sound leakage after the door is closed, thus hindering the improvement of vehicle performance. Utility Model Content

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

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0006] A door frame sealing strip includes a sealing strip body and a sealing bubble tube located on one side of the sealing strip body;

[0007] A first bubble tube cavity is formed between the sealing bubble tube and the sealing strip body. A support portion is provided in the first bubble tube cavity on the sealing strip body. The support portion protrudes toward the sealing bubble tube.

[0008] The sealing bubble tube is provided with an exhaust hole, which connects the first bubble tube cavity to the outside. From the cross-section of the door frame sealing strip, the exhaust hole is located on the side of the support part. When the sealing bubble tube is squeezed, the support part can suppress the deformation of the position where the exhaust hole is located.

[0009] Furthermore, the top of the support portion in the protruding direction has a support plane, which is parallel to the sealing surface on the door after the vehicle door is closed.

[0010] Furthermore, the inner wall of the sealing bubble tube is provided with several protrusions, and when the sealing bubble tube is squeezed and abuts against the support, the protrusions contact the support.

[0011] Furthermore, from the cross-section of the door frame sealing strip, the first bubble tube cavity is teardrop-shaped, and the outer contour of the sealing bubble tube follows the shape of the first bubble tube cavity.

[0012] Furthermore, the support portion includes a support bubble tube, and a second bubble tube cavity is formed between the support bubble tube and the sealing strip body.

[0013] Furthermore, the sealing bubble tube is made of sponge adhesive, and the supporting bubble tube is made of solid adhesive.

[0014] Furthermore, from the cross-section of the door frame sealing strip, the supporting bubble tube has roots located on both sides, and a bubble tube body located between the roots on both sides;

[0015] The roots on both sides are connected to the main body of the sealing strip, and the thickness of the main body of the bubble tube is the same at all positions.

[0016] Furthermore, the second bubble cavity is not connected to the first bubble cavity.

[0017] Compared with related technologies, this application has the following advantages:

[0018] (1) The door frame sealing strip described in this application, by setting a support portion protruding to one side of the sealing bubble tube, and setting the exhaust hole on the sealing bubble tube corresponding to the side of the support portion, can increase the sealing force of the sealing bubble tube by utilizing the supporting effect of the support portion, and avoid excessive deformation and collapse of the sealing bubble tube, so as to ensure the sealing effect. At the same time, when the sealing bubble tube is squeezed, the support portion can also suppress the deformation of the position of the exhaust hole, ensuring the smooth air discharge in the sealing bubble tube, avoiding excessive door closing force, and thus improving the quality of vehicle use.

[0019] (2) The top of the support part has a support plane, and after the door is closed, the support plane is parallel to the sealing surface on the door. After the door is closed, the sealing bubble tube deforms and is in zero contact with the sealing surface on the door. This ensures that the support area and support force of the support part for the sealing bubble tube are at their maximum after the door is closed, which helps to provide the support effect of the support part and the sealing effect of the sealing bubble tube.

[0020] (3) Protrusions are set on the inner wall of the sealing bubble tube. When the sealing bubble tube is squeezed and abuts against the support, the protrusions on the sealing bubble tube contact the support. This can prevent the sealing bubble tube from deforming and sticking to the support, thus preventing a large area of ​​adhesion and abnormal noise.

[0021] (4) Make the first bubble tube cavity into a teardrop shape, and make the outer contour of the sealing bubble tube follow the shape of the first bubble tube cavity. This makes the sealing bubble tube also teardrop-shaped. Compared with the traditional semi-circular cross-section, this increases the contact area between the sealing bubble tube and the door sealing surface after the door is closed, which helps to improve the sealing effect of the sealing bubble tube.

[0022] (5) The support part adopts a support bubble tube that forms a second bubble cavity with the main body of the sealing strip. Compared with a solid support structure, it can not only reduce the material used in the support part, which helps to reduce the manufacturing cost of the sealing strip and help to achieve the lightweight of the sealing strip, but also helps to control the rigidity of the support part. This can avoid the support part being too hard, causing the door closing force to be too large, which affects the convenience and feel of the door closing operation.

[0023] (6) The sealing bubble tube is made of sponge adhesive and the supporting bubble tube is made of solid adhesive. Based on the bubble tube structure in the support part, the different materials of the supporting bubble tube and the sealing bubble tube make the supporting bubble tube slightly harder than the sealing bubble tube. After the car door is closed, the supporting bubble tube is less likely to deform, which can provide better support for the sealing bubble tube and help ensure the sealing effect of the sealing bubble tube.

[0024] (7) By making the thickness of each part of the main body of the support bubble tube the same, the support bubble tube can be designed with equal thickness as a whole. The equal thickness design of the support bubble tube can be used to avoid the support bubble tube being too thick in some parts, which would cause the local support force of the support bubble tube to be too large, so that the sealing bubble tube and the sealing surface on the car door cannot fit well, thus affecting the sealing effect of the sealing bubble tube.

[0025] (8) The second bubble tube cavity is not connected to the first bubble tube cavity. By not setting an exhaust hole on the support bubble tube, the amount of air in the first bubble tube cavity is less than that of the traditional bubble tube cross section. Less air flows through the exhaust hole on the sealed bubble tube during the closing of the car door, thereby improving the sound quality when the car door is opened and closed. At the same time, it can also avoid the knocking sound generated by the traditional bubble tube cross section during the opening and closing of the car door, as well as the airflow sound during the closing of the car door, which can further improve the quality of vehicle use.

[0026] This application also proposes a vehicle in which a door frame sealing strip as described above is provided.

[0027] Furthermore, the vehicle is a frameless model, and the door frame sealing strip is used for sealing between the door glass and the side door frame in the vehicle.

[0028] By installing the aforementioned door frame sealing strip, the vehicle described in this application can increase the sealing force of the sealing bubble tube, prevent the sealing bubble tube from collapsing due to excessive deformation, ensure the sealing effect of the sealing strip, and also ensure the smooth expulsion of air from the sealing bubble tube after the door is closed. This can prevent the door from closing with excessive force and thus improve the quality of vehicle use.

[0029] Furthermore, by applying the aforementioned door frame sealing strips to frameless vehicles, it is possible to adapt to the characteristic of frameless vehicles that do not have window frame sheet metal, ensuring the sealing force of the door frame sealing strips and the sealing effect between the door frame sealing strips and the door glass, thereby improving the sealing quality of frameless vehicles.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] An embodiment of the first aspect of this application provides a door frame sealing strip, which is applied to a vehicle to achieve a seal between the side door frame and the door in the vehicle. Furthermore, the door frame sealing strip of this embodiment is particularly suitable for frameless vehicle models where there is no window frame sheet metal on the door.

[0047] Meanwhile, the door frame sealing strip in this embodiment, through its innovative structural design, can increase the sealing force of the door frame sealing strip, which helps to improve the sealing effect of the door frame sealing strip and thus improve the quality of vehicle use.

[0048] In related technologies, in order to prevent water or dust from entering the car door and to reduce vehicle noise while driving, sealing strips are usually installed at the side door frame and the door to seal the area, thereby preventing rainwater and dust from entering and reducing vehicle noise while driving.

[0049] Currently, in traditional vehicle door sealing designs, there are generally two sealing strips used for sealing the door area: one is the door sealing strip, and the other is the door frame sealing strip. The door sealing strip is mounted on the door sheet metal, while the door frame sealing strip is mounted on the side sheet metal, specifically the side door frame. After the door is closed, the door sealing strip works in conjunction with the side of the vehicle body to provide sealing, dust prevention, and sound insulation. Simultaneously, the door frame sealing strip works in conjunction with the door, also providing sealing, dust prevention, and sound insulation.

[0050] In addition, whether it is a door sealing strip or a door frame sealing strip, the sealing strip is generally designed with a bubble tube structure. After the door is closed, the bubble tube structure abuts against the door or the side panel of the car body to achieve the required sealing effect.

[0051] However, due to limitations in materials and structure, current door sealing strips still suffer from insufficient sealing power. This is particularly noticeable in frameless models—those without window frames on the doors and lacking door sealing strips at five points on the door glass, requiring direct contact between the door frame sealing strip and the door glass for sealing. In these cases, insufficient sealing power can easily lead to water and sound leaks after the doors are closed, negatively impacting the user experience.

[0052] Furthermore, while some current door sealing structures incorporate support structures within the sealing strip to reduce the collapse of the bubble tube, these structures still suffer from limitations. The bubble tube is connected to the clamping part (the main structure of the sealing strip) via an elastic connector. The support structure indirectly supports the bubble tube by supporting the elastic connector, and this elastic connector also bends when the bubble tube deforms. This results in limited support for the bubble tube and also affects the exhaust efficiency when the bubble tube deforms, leading to greater door closing force and ultimately hindering the improvement of vehicle performance.

[0053] In view of this, in order to overcome the shortcomings of related technologies, the door frame sealing strip in this embodiment incorporates... Figure 1 As shown, the overall design includes a sealing strip body 1 and a sealing bubble tube 2 located on one side of the sealing strip body 1.

[0054] The sealing bubble tube 2 and the sealing strip body 1 form a first bubble tube cavity M. A support part 3 is provided in the first bubble tube cavity M on the sealing strip body 1. The support part 3 protrudes towards the sealing bubble tube 2. At the same time, an exhaust hole 202 is also provided on the sealing bubble tube 2. The exhaust hole 202 connects the first bubble tube cavity M with the outside. From the cross-section of the door frame sealing strip, the exhaust hole 202 is provided corresponding to the side 3b of the support part 3 so that when the sealing bubble tube 2 is squeezed, the support part 3 can suppress the deformation of the position where the exhaust hole 202 is located.

[0055] Therefore, by providing a support portion 3 protruding towards the side of the sealing bubble tube 2 in the first bubble tube cavity M, and making the vent hole 202 on the sealing bubble tube 2 correspond to the side portion 3b of the support portion 3, this embodiment can, on the one hand, utilize the supporting effect of the support portion 3 to increase the sealing force of the sealing bubble tube 2, prevent the sealing bubble tube 2 from collapsing due to excessive deformation, and thus ensure the sealing effect. On the other hand, when the sealing bubble tube 2 is squeezed, the support portion 3 can also be used to suppress the deformation of the vent hole 202, ensuring the smooth discharge of air from the sealing bubble tube 2, avoiding excessive door closing force, and thus improving the quality of vehicle use.

[0056] Based on the above overview, specifically, it remains as follows: Figure 1 As shown, the sealing strip body 1 serves as the main structure of the door frame sealing strip in this embodiment. It is mainly used to realize the installation of the door frame sealing strip on the vehicle, and as the basis for setting up structures such as the sealing bubble tube 2 and the support part 3, so as to form the entire door frame sealing strip together with the sealing bubble tube 2 and the support part 3.

[0057] In specific implementations, in some exemplary embodiments, to achieve the installation arrangement of the door frame sealing strip on the vehicle, for example, an installation groove 101 can be provided on the sealing strip body 1. When installing the door frame sealing strip, it can be done as follows: Figure 2 As shown, the edge of the side panel sheet 4 in the vehicle body is inserted into the mounting groove 101, thereby installing the door frame sealing strip to the door frame position in the vehicle body.

[0058] Furthermore, in order to increase the stability of the door frame sealing strip installation on the side sheet metal 4, in addition to using the mounting groove 101 for door frame sealing strip installation, this embodiment may, for example, provide a snap-fit ​​lip 102 on the wall of the mounting groove 101 on the sealing strip body 1, and at the same time, a snap-fit ​​protrusion 103 may be provided on the wall of the mounting groove 101.

[0059] The aforementioned snap-fit ​​lip 102 extends towards the bottom of the mounting groove 101 to form a barbed design, thereby providing better anti-detachment capability. Specifically, the snap-fit ​​lip 102 can be located on one side of the mounting groove 101, and correspondingly, the snap-fit ​​protrusion 103 can be located on the other side of the mounting groove 101, and the snap-fit ​​protrusion 103 can protrude in the direction pointing towards the other side of the mounting groove 101.

[0060] It is understandable that by providing the aforementioned snap-fit ​​lip 102 and snap-fit ​​protrusion 103 within the mounting groove 101, it can achieve the following: Figure 2 As shown, by abutting against both sides of the side panel 4, the clamping force of the door frame sealing strip after installation on the side panel 4 is increased, thereby achieving the effect of stable installation of the door frame sealing strip.

[0061] Furthermore, in practical implementation, the aforementioned snap-fit ​​lips 102 and snap-fit ​​protrusions 103 can generally be arranged side by side on the wall of the mounting groove 101. In this way, the snap-fit ​​force of the door frame sealing strip can be better through multiple snap-fit ​​lips 102 and multiple snap-fit ​​protrusions 103, thereby improving the stability of the door frame sealing strip installation.

[0062] In this embodiment, the installation arrangement of the door frame sealing strip in the vehicle using the mounting groove 101 is still taken as an example. In some exemplary embodiments, in order to increase the stability of the door frame sealing strip installed on the side sheet metal 4, such as... Figure 1 and Figure 2 As shown, for example, a skeleton 106 can also be embedded in the body 1 of the sealing strip.

[0063] The frame 106 can generally be made of metal, typically steel or aluminum. Furthermore, in its specific design, the cross-section of the door frame sealing strip, that is, from... Figure 1 or Figure 2 As can be seen, the skeleton 106 can be set around the mounting groove 101, and the whole has an "n" structure.

[0064] It is understandable that by embedding a steel or aluminum skeleton 106 within the sealing strip body 1, the clamping force of the door frame sealing strip during installation through the mounting groove 101 can be further improved. Of course, when the sealing strip body 1 is simultaneously equipped with the aforementioned skeleton 106, clamping lip 102, and clamping protrusion 103, the cooperation of the skeleton 106, clamping lip 102, and clamping protrusion 103 obviously provides better clamping ability, resulting in better clamping force of the door frame sealing strip and further improving the stability of the door frame sealing strip installation.

[0065] It should be noted that, in specific implementation, the main body 1 of the sealing strip can generally be made of EPDM (Ethylene Propylene Diene Monomer) solid rubber. By taking advantage of the slightly higher hardness of EPDM solid rubber, the clamping force during the installation of the door frame sealing strip can be improved to a certain extent, thereby enhancing the stability of the door frame sealing strip installation.

[0066] In addition, in some exemplary embodiments, this embodiment may also provide a first sealing lip 104 and a second sealing lip 105 on the sealing strip body 1.

[0067] The first sealing lip 104 is located on the other side of the sealing strip body 1 relative to the sealing bubble tube 2. When the door frame sealing strip is installed in the vehicle, the first sealing lip 104 can abut against the surrounding structure (such as trim panels) in the vehicle body to play the role of sealing and covering decoration.

[0068] The second sealing lip 105 is located on the side of the sealing strip body 1 where the sealing bubble tube 2 is located, and the second sealing lip 105 is also located at the groove opening of the mounting groove 101, and is arranged on the same side as the aforementioned snap-fit ​​protrusion 103. When the door frame sealing strip is installed on the side panel 4, the second sealing lip 105 abuts against the side panel 4, and can also play the role of sealing and covering decoration.

[0069] In specific implementation, the first sealing lip 104 and the second sealing lip 105 can also be made of EPDM solid adhesive, for example. However, in addition to using EPDM solid adhesive, as a more preferred implementation, the first sealing lip 104 and the second sealing lip 105 can also be made of the same adhesive as the sealing bubble tube 2. This allows for better sealing by utilizing the fact that the sealing bubble tube 2 is usually made of sponge adhesive, which has a slightly lower hardness.

[0070] In this embodiment, we continue to combine Figure 1 and Figure 2 As shown, in some exemplary embodiments, the top of the support portion 3 in the protruding direction may be provided with a support plane 3a, and the arrangement is such that when the vehicle door is closed, the support plane 3a is parallel to the sealing surface 5a on the door.

[0071] In this example, the vehicle is a frameless model, and the door frame sealing strip in this embodiment is used for sealing between the vehicle body door frame and the door glass 5. At this point, refer back to... Figure 2The sealing surface 5a on the car door is the inner end face of the door glass 5 facing the inside of the car. When the car door is closed and the door glass 5 is in the raised state, the sealing bubble tube 2 in the door frame sealing strip of this embodiment abuts against the sealing surface 5a of the door glass 5. As the sealing bubble tube 2 is deformed by the pressure of the door glass 5, the support part 3 provides support force to the sealing bubble tube 2 to ensure the sealing effect between the sealing bubble tube 2 and the door glass 5.

[0072] It is understandable that by making the top of the support part 3 have a support plane 3a, and after the car door is closed, the support plane 3a is also parallel to the sealing surface 5a on the car door. This embodiment can ensure that the support area and support force of the support part 3 on the sealing bubble tube 2 are at their maximum after the car door is closed, when the sealing bubble tube 2 is deformed and there is no contact between it and the sealing surface 5a on the car door. This helps to provide the support effect of the support part 3 and the sealing effect of the sealing bubble tube 2.

[0073] Continue as Figure 1 As shown, in some exemplary embodiments of this embodiment, for example, a plurality of protrusions 201 may be provided on the inner wall of the sealing bubble tube 2, and when the sealing bubble tube 2 is squeezed and abuts against the support portion 3, the protrusions 201 contact the support portion 3.

[0074] At this time, by setting protrusions 201 on the inner wall of the sealing bubble tube 2, and when the sealing bubble tube 2 is squeezed against the support part 3 by a device such as the door glass 5, the sealing bubble tube 2 contacts the support part 3 through the protrusions 201. Obviously, compared with the case where the inner wall of the sealing bubble tube 2 is a smooth plane, it can prevent the sealing bubble tube 2 from deforming and sticking to the support part 3, thus avoiding the problem of sticking and abnormal noise. This can avoid affecting the sound quality at the door.

[0075] In specific implementation, the size and number of the protrusions 201 located on the inner wall of the sealing bubble tube 2 can be determined according to the door frame sealing strip, especially the overall size and specifications of the sealing bubble tube 2 and the support part 3. There is no limitation here, as long as they can effectively prevent the sealing bubble tube 2 and the support part 3 from sticking together and do not have an adverse effect on the deformation of the sealing bubble tube 2 and the sealing effect.

[0076] In this embodiment, in some exemplary implementations, the following continues... Figure 1 As shown, from the cross-section of the door frame sealing strip, the first bubble cavity M can be designed as a teardrop shape, and the outer contour of the sealing bubble tube 2 is also set to conform to the shape of the first bubble cavity M.

[0077] Among them, for the first bubble cavity M, which is teardrop-shaped, its large end and small end are specifically as follows: Figure 1As shown, they are located on opposite sides of the support portion 3. By making the first bubble cavity M teardrop-shaped and the outer contour of the sealing bubble tube 2 conforming to the shape of the first bubble cavity M, it can be understood that the sealing bubble tube 2 as a whole is also teardrop-shaped. Compared with the traditional semi-circular cross-section, this increases the contact area between the sealing bubble tube 2 and the sealing surface 5a on the door after the door is closed, thereby helping to improve the sealing effect of the sealing bubble tube 2.

[0078] In this embodiment, in some exemplary implementations, see also... Figure 1 As shown, the support portion 3 located in the first bubble cavity M may include, for example, a support bubble tube 30, and the support bubble tube 30 also forms a second bubble cavity N between itself and the sealing strip body 1.

[0079] At this time, the support part 3 adopts a support tube that forms a second bubble cavity N with the sealing strip body 1. Compared with a solid support structure, this not only reduces the material used in the support part 3, which helps to reduce the manufacturing cost of the door frame sealing strip in this embodiment, but also helps to achieve lightweight door frame sealing strip. At the same time, it is also beneficial to control the rigidity of the support part 3, which can avoid the support part 3 being too stiff, causing the door closing force to be too large, which would have an adverse effect on the convenience and feel of the door closing operation.

[0080] Based on the support tube 30 used in the support part 3, as one of the exemplary embodiments, this embodiment may, for example, make the sealing tube 2 use sponge adhesive and the support tube 30 use solid adhesive.

[0081] In specific implementation, the sealing bubble tube 2 can be made of EPDM sponge adhesive, while the supporting bubble tube 30 can be made of TPV (Thermoplastic Vulcanizate) solid adhesive.

[0082] Furthermore, by using sponge adhesive for the sealing bubble tube 2 and solid adhesive for the supporting bubble tube 30, this embodiment can utilize the difference in materials between the supporting bubble tube 30 and the sealing bubble tube 2, based on the bubble tube structure of the supporting part 3, to make the hardness of the supporting bubble tube 30 slightly greater than that of the sealing bubble tube 2. This makes the supporting bubble tube 30 less prone to deformation after the car door is closed, and can provide better support for the sealing bubble tube 2, so as to ensure the sealing effect of the sealing bubble tube 2.

[0083] In this embodiment, in some exemplary implementations, still viewed from the cross-section of the door frame sealing strip, the supporting tube 30 may structurally have roots 301 located on both sides, and a tube body 302 located between the two roots 301. The two roots 301 are connected to the sealing strip body 1, and the thickness of the tube body 302 at each location may be designed to be the same.

[0084] At this time, since the root 301 on both sides of the sealing support tube 30 that is connected to the sealing strip body 1 is generally a very small part of the entire support tube 30, the thickness of each position of the tube body 302 is the same, so the support tube 30 as a whole adopts a uniform thickness design.

[0085] By ensuring that the thickness of each position of the main body 302 of the support bubble tube 30 is the same, the support bubble tube 30 is designed with uniform thickness as a whole. In this embodiment, the uniform thickness design of the support bubble tube 30 can be used to avoid excessive local support force caused by excessive thickness in some parts of the support bubble tube 30, which would prevent the sealing bubble tube 30 from fitting well with the sealing surface 5a on the door and thus affect the sealing effect of the sealing bubble tube 2.

[0086] In this embodiment, it is worth noting that the exhaust port 202 is provided corresponding to the side portion 3b of the support portion 3, that is, as described above. Figure 1 or Figure 2 As shown, the vent 202 is located on one side of the sealing bubble tube 2, rather than on the top of the sealing bubble tube 2 that abuts against the sealing surface 5a on the door. Figure 2 (As shown in the orientation), and in a direction perpendicular to the protrusion direction of the support 3, the projections of the vent 202 and the support 3 at least partially overlap.

[0087] By adopting the above configuration for the vent 202, when the car door is closed and the sealing bubble tube 2 is compressed, the deformation of the vent 202 position on the sealing bubble tube 2 can be suppressed by the support of the support part 3, so that the vent 202 can be kept in the open state, thereby avoiding affecting the vent 202's exhaust effect.

[0088] It is worth noting that the above-mentioned vent holes 202 are provided corresponding to the side 3b of the support part 3. In specific implementation, the vent holes 202 can be provided entirely corresponding to the side 3b of the support part 3, or a part of the vent holes 202 can be provided corresponding to the side 3b of the support part 3. It can be determined according to the size and specifications of the support part 3 and the vent holes 202. As long as the vent holes 202 are located on one side of the sealing bubble tube 2 and the support of the support part 3 can be used to suppress the deformation of the position of the vent holes 202 when the sealing bubble tube 2 is squeezed and deformed, it is acceptable.

[0089] Furthermore, based on the provision of an exhaust port 202 on the sealed bubble tube 2, in some exemplary embodiments, such as this embodiment, the second bubble tube cavity N located inside the supporting bubble tube 30 may be not connected to the first bubble tube cavity M outside the supporting bubble tube 30.

[0090] In this embodiment, the second bubble tube N is not connected to the first bubble tube M, meaning that the exhaust hole 202 is not provided on the supporting bubble tube 30 in this embodiment.

[0091] At this point, by not providing an exhaust hole 202 on the supporting bubble tube 30, it can be understood that this embodiment can reduce the amount of air in the first bubble tube cavity M compared to the traditional bubble tube cross-section. Less air flows through the exhaust hole 202 on the sealed bubble tube 2 during the door closing process, thereby improving the sound quality when the door is opened and closed. It can also avoid the slapping sound generated by the traditional bubble tube cross-section during the door opening and closing process, as well as the airflow sound during the door closing process, which can further improve the vehicle's usability.

[0092] It is worth noting that, regarding the door frame 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 and Figure 2 As shown, it may include, for example, a sealing strip body 1 and a sealing bubble tube 2 located on one side of the sealing strip body 1.

[0093] The sealing bubble tube 2 forms a first bubble cavity M between itself and the sealing strip body 1. A support portion 3 is disposed within the first bubble cavity M, located on the sealing strip body 1. This support portion 3 protrudes towards the sealing bubble tube 2 and specifically adopts a support bubble tube 30 that forms a second bubble cavity N between itself and the sealing strip body 1. Simultaneously, an vent hole 202 is provided on the sealing bubble tube 2. From the cross-section of the door frame sealing strip, the vent hole 202 corresponds to the side portion 3b of the support portion 3, allowing the support portion 3 to suppress deformation at the location of the vent hole 202 when the sealing bubble tube 2 is compressed.

[0094] The sealing strip body 1 is provided with a first sealing lip 104 and a second sealing lip 105. A supporting plane 3a is provided at the top of the supporting part 3 in the protruding direction. After the door is closed, the supporting plane 3a is parallel to the sealing surface 5a on the door. In addition, several protrusions 201 for abutting against the supporting part 3 are provided on the inner wall of the sealing tube 2. The outer contour of the sealing tube 2 is also teardrop-shaped, following the shape of the first tube cavity M. In addition, the sealing tube 30 adopts a uniform thickness design. The sealing strip body 1 can be made of EPDM solid adhesive, the sealing tube 2 can be made of EPDM sponge adhesive, and the supporting tube 30 can be made of TPV solid adhesive. Furthermore, the second tube cavity N is not connected to the first tube cavity M.

[0095] In the specific preparation process, for example, the door frame sealing strip of this embodiment can be prepared by a multi-material co-extrusion molding method. Meanwhile, the thickness of the support bubble tube 30 is generally 1mm-2mm, and the diameter of the vent hole 202 on the sealing bubble tube 2 can be determined according to the overall size and specifications of the door frame sealing strip. Specifically, the diameter of the vent hole 202 can be, for example, between 3mm-4mm.

[0096] In the preferred embodiment of the door frame sealing strip above, the specific setting and arrangement of the support part 3 of the support bubble tube 30 and the vent hole 202 on the sealing bubble tube 2 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 support part 3, vent hole 202, etc. can also be referred to the description in the above exemplary embodiments.

[0097] The door frame sealing strip of this embodiment adopts the above design. By setting a support part 3 that can support the bubble tube 30, and setting the vent hole 202 on the sealing bubble tube 2 to correspond to the side of the support bubble tube 30, the supporting effect of the support bubble tube 30 can be used to increase the sealing force of the sealing bubble tube 2, prevent the sealing bubble tube 2 from collapsing due to excessive deformation, and ensure the sealing effect. At the same time, when the sealing bubble tube 2 is squeezed, the support bubble tube 30 can suppress the deformation of the vent hole 202, ensuring the smooth exhaust of air in the sealing bubble tube 2, avoiding excessive door closing force, and thus improving the quality of vehicle use.

[0098] An embodiment of the second aspect of this application provides a vehicle having a door frame sealing strip as described in the above embodiment.

[0099] In some exemplary embodiments, the vehicle in this embodiment is preferably a frameless model, and the aforementioned door frame sealing strip is specifically used for sealing between the door glass 5 and the side door frame in the vehicle.

[0100] Specifically, when used on frameless vehicles and for sealing between the door glass 5 and the side door frame, the aforementioned door frame sealing strip can generally be in an "n" shape and is only installed on the upper half of the side door frame, that is, on the side door frame above the body waistline. The lower half of the side door frame, since it fits with the door sheet metal, can still use the traditional sealing method.

[0101] In this embodiment, by setting the aforementioned door frame sealing strip, the sealing force of the sealing bubble tube 2 in the door frame sealing strip can be increased, preventing the sealing bubble tube 2 from collapsing due to excessive deformation. This ensures the sealing effect of the door frame sealing strip and also ensures the smooth expulsion of air from the sealing bubble tube 2 after the door is closed, preventing excessive door closing force and thus improving the quality of vehicle use.

[0102] Furthermore, by applying the aforementioned door frame sealing strip to frameless vehicles, this embodiment can also adapt to the characteristic of frameless vehicles without window frame sheet metal, ensuring the sealing force of the door frame sealing strip and the sealing effect between the door frame sealing strip and the door glass 5, thereby improving the sealing quality of frameless vehicles.

[0103] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
