[0030] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0032] This application provides a vehicle door frame sealing strip 100, a door assembly 200, and a vehicle. The vehicle door frame sealing strip 100, door assembly 200, and vehicle of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0033] See Figure 1 As shown, this application provides a vehicle door frame sealing strip 100, including a main body 10, a connecting part 20, and a sealing part 30. The connecting part 20 is disposed on the main body 10 for connecting to the vehicle door frame 210. The sealing part 30 includes a first sealing bubble 31 and a second sealing bubble 32. The first sealing bubble 31 and the second sealing bubble 32 are disposed on the same side of the main body 10, specifically, when the vehicle door frame sealing strip 100 is installed on the vehicle door frame 210, the main body 10 faces the side of the glass 221 of the door 220. The first sealing bubble 31 includes a first contact surface 311, and the second sealing bubble 32 includes a second contact surface 321. The distance between the first contact surface 311 and the main body 10 is greater than the distance between the second contact surface 321 and the main body 10.

[0034] Specifically, the vehicle door frame sealing strip 100 in this application is connected between the upper section sealing strip and the side section sealing strip of the door frame 210 of the door 220, and is used as a corner sealing strip.

[0035] By setting a first sealing bubble 31 and a second sealing bubble 32, the vehicle door frame sealing strip 100 can form two seals when it mates with the glass 221 of the door 220 through the first contact surface 311 and the second contact surface 321 respectively. The distance between the first contact surface 311 and the main body 10 is greater than the distance between the second contact surface 321 and the main body 10. The seal between the first contact surface 311 and the glass 221 of the door 220 reduces most of the air intake, and the second contact surface 321 further reduces the air intake, thereby improving the NVH effect during high-speed vehicle operation.

[0036] In an optional embodiment, see Figure 1 As shown, the first sealing bubble 31 includes a first side surface 312 facing the second sealing bubble 32. The second sealing bubble 32 includes a second side surface 322 facing the first sealing bubble 31. The second side surface 322 and the first side surface 312 are spaced apart and enclose each other to form a drainage channel 40. Specifically, in this embodiment, the first side surface 312, the second side surface 322, and the main body 10 enclose each other to form the drainage channel 40.

[0037] The sealing between the first contact surface 311 and the glass 221 of the door 220 reduces water ingress through the first contact surface 311. When water does enter through the first contact surface 311, it can drain out along the drainage channel 40. Furthermore, a second seal is formed between the second contact surface 321 and the glass 221 of the door 220, further reducing the risk of water ingress into the vehicle and thus improving the vehicle's water-tightness. The first sealing bubble 31 makes the drainage channel 40 concealed; simultaneously, the above design ensures sufficient drainage space, preventing water accumulation and the risk of icing.

[0038] In an optional embodiment, see Figure 1 As shown, the vehicle door frame sealing strip 100 also includes a first reinforcing plug 70, which is disposed within the first sealing bubble 31. The cross-sectional shape of the first reinforcing plug 70 matches the cross-sectional shape of the inner cavity of the first sealing bubble 31. Specifically, the first reinforcing plug 70 is partially disposed 100 mm along the length direction of the vehicle door frame sealing strip 100.

[0039] By setting the first reinforcing plug 70, the contact between the first contact surface 311 of the first sealing bubble 31 and the glass 221 of the door 220 is supported, thereby improving the sealing effect of the first sealing bubble 31 and thus improving the NVH effect during high-speed driving.

[0040] In an optional embodiment, the vehicle door frame sealing strip 100 further includes a second reinforcing plug disposed within the second sealing bubble 32, the cross-sectional shape of the second reinforcing plug matching the cross-sectional shape of the inner cavity of the second sealing bubble 32.

[0041] By setting a second reinforcing plug, the contact between the second contact surface 321 of the second sealing bubble 32 and the glass 221 of the door 220 is supported, thereby improving the sealing effect of the second sealing bubble 32 and thus improving the NVH effect during high-speed vehicle operation.

[0042] The first reinforcing plug 70 and the second reinforcing plug can be made of EPDM (ethylene propylene diene monomer rubber) with a foaming density of 0.03 g / cm3.

[0043] In an optional embodiment, see Figure 1As shown, the vehicle door frame sealing strip 100 includes a first lip 50 disposed on the main body 10. The first lip 50 and the second sealing bubble 32 are located on both sides of the main body 10. The first lip 50 is used to abut against the door frame 210, specifically against the side sheet metal 212 of the door frame 210, thereby achieving a water seal between the first lip 50 and the door frame 210. Specifically, the first lip 50 is formed by the existing connection between the upper section sealing strip and the side section sealing strip of the door 220 door frame 210 and the door frame 210, ensuring the sealing effect between the vehicle door frame sealing strip 100 and the door frame 210.

[0044] In an optional embodiment, see Figure 1 As shown, the connecting part 20 includes a locking groove 21. The locking groove 21 is disposed on the main body part 10, and the locking groove 21 and the first sealing bubble 31 are located on both sides of the main body part 10. The locking groove 21 is used to engage with the door frame 210. In the length direction of the main body part 10, the first sealing bubble 31 extends out of the locking groove 21.

[0045] Specifically, the locking groove 21 is provided with elastic teeth. When the end of the side sheet metal 212 of the door frame 210 is inserted into the locking groove 21, the contact elastic teeth at the end of the door frame 210 are squeezed, and the elastic teeth bend towards the bottom of the locking groove 21 under the force of the folding edge. After the end of the door frame 210 is inserted into the locking groove 21, the elastic teeth generate a restoring force under bending deformation, causing the elastic teeth to abut against the end of the door frame 210, thereby realizing the locking groove 21 and the door frame 210 engaging, facilitating the installation of the vehicle door frame sealing strip 100, thus improving the reliability of the connection between the vehicle door frame sealing strip 100 and the door frame 210, improving the installation tightness of the vehicle door frame sealing strip 100, and reducing the risk of the vehicle door frame sealing strip 100 detaching from the door frame 210.

[0046] In an optional embodiment, see Figure 1 As shown, the vehicle door frame sealing strip 100 includes a second lip 60, which is disposed at the end of the main body 10 along the length direction and extends in a direction away from the first sealing bubble 31. The second lip 60 and the locking groove 21 are spaced apart along the length direction of the main body 10.

[0047] When the vehicle door frame sealing strip 100 is engaged with the door frame 210, the end of the door frame 210 is embedded in the locking groove 21, and the interior trim 213 of the door frame 210 is embedded in the gap between the second lip 60 and the locking groove 21. The second lip 60 covers the connection between the vehicle door frame sealing strip 100 and the door frame 210, which is beneficial to the aesthetics of the vehicle door frame sealing strip 100.

[0048] In an optional embodiment, see Figure 1As shown, the connecting part 20 includes a clamping claw 22, which is connected to the main body 10. The clamping claw 22 is disposed on the side of the second sealing bubble 32 opposite to the first sealing bubble 31, and is used to engage with the door frame 210.

[0049] Specifically, the clamping claw 22 is provided with elastic teeth. In this embodiment, the clamping claw 22 engages with the decorative panel 211 of the door frame 210. When the clamping claw 22 engages with the door frame 210, the door frame 210 contacts the elastic teeth and compresses them, causing the elastic teeth to bend under the force of the door frame 210. When the clamping claw 22 is inserted into the door frame 210, the elastic teeth generate a restoring force under bending deformation, causing the elastic teeth to abut against the door frame 210, thereby achieving the engagement between the clamping claw 22 and the door frame 210. This facilitates the installation of the vehicle door frame sealing strip 100, thereby improving the reliability of the connection between the vehicle door frame sealing strip 100 and the door frame 210, improving the installation tightness of the vehicle door frame sealing strip 100, and reducing the risk of the vehicle door frame sealing strip 100 detaching from the door frame 210.

[0050] In an optional embodiment, see Figure 2 As shown, the vehicle door frame sealing strip 100 also includes a blocking portion 80, which is disposed on the main body portion 10. The blocking portion 80 and the sealing portion 30 are located on the same side of the main body portion 10, and the blocking portion 80 is used to bond with the door frame 210.

[0051] In this way, the inner side of the shielding part 80 and the door frame 210 form a consistent shape, so that there are no parts or parting surfaces between the vehicle door frame sealing strip 100 and the upper and side sealing strips of the adjacent door frame 210, achieving a better detail effect.

[0052] This application also provides a door assembly 200, see [link to relevant documentation] Figure 1 and Figure 2 As shown, the vehicle includes a door frame 210, a door 220 mounted on the door frame 210, and a door frame sealing strip 100. The door 220 includes glass 221. The door frame sealing strip 100 is disposed between the door 220 and the door frame 210, with a connecting portion 20 connected to the door frame 210. Both the first sealing bubble 31 and the second sealing bubble 32 abut against the glass 221.

[0053] In this way, when the vehicle door frame sealing strip 100 cooperates with the glass 221 of the door 220, it can form two seals through the first contact surface 311 and the second contact surface 321 respectively. The distance between the first contact surface 311 and the main body 10 is greater than the distance between the second contact surface 321 and the main body 10. The seal between the first contact surface 311 and the glass 221 of the door 220 reduces most of the air intake, and the second contact surface 321 further reduces the air intake, thereby improving the NVH effect during high-speed vehicle operation.

[0054] In an optional embodiment, the interference between the first sealing bubble 31 and the glass 221 is 3 to 4 millimeters, specifically 3.2 millimeters, 3.5 millimeters, 3.7 millimeters, etc.

[0055] In an optional embodiment, the interference between the second sealing bubble 32 and the glass 221 is 2 to 3 millimeters, specifically 2.2 millimeters, 2.5 millimeters, 2.7 millimeters, etc.

[0056] In this way, excessive interference between the first sealing bubble 31, the second sealing bubble 32 and the glass 221 can be avoided, which would cause excessive compression of the first sealing bubble 31 and the second sealing bubble 32 relative to the glass 221. At the same time, the sealing effect between the first sealing bubble 31 and the glass 221, and between the second sealing bubble 32 and the glass 221 can be ensured, thereby improving the NVH effect during high-speed vehicle operation.

[0057] Furthermore, the first sealing bubble 31 interferes with the glass 221 to form a first contact surface 311, and the second sealing bubble 32 interferes with the glass 221 to form a second contact surface 321. Both the first contact surface 311 and the second contact surface 321 are ensured to have a width of 3 mm, thereby improving the NVH effect during high-speed vehicle operation.

[0058] This application also provides a vehicle, which includes a door assembly 200.

[0059] In this way, when the vehicle door frame sealing strip 100 cooperates with the glass 221 of the door 220, it can form two seals through the first contact surface 311 and the second contact surface 321 respectively. The distance between the first contact surface 311 and the main body 10 is greater than the distance between the second contact surface 321 and the main body 10. The seal between the first contact surface 311 and the glass 221 of the door 220 reduces most of the air intake, and the second contact surface 321 further reduces the air intake, thereby improving the NVH effect during high-speed vehicle operation and enhancing the driving and riding experience.

[0060] The vehicle door frame sealing strip 100, door assembly 200, and vehicle of this application have the following improvements:

[0061] 1. Through the structural innovation of the vehicle door frame sealing strip 100 at the corner, the shape between it and the front trim panel of the door frame 210 is smoother, and the internal structural details of the side sheet metal 212 when the door 220 is opened are more refined, which has competitive styling, improves the daily driving experience of customers, and thus enhances the competitiveness of the product in the automotive market.

[0062] 2. Two sealing bubble structures were added between the glass 221 and the vehicle door frame sealing strip 100, and the sealing bubble was designed with a reinforcing plug to increase the NVH wind noise capability at high speeds; a drainage structure was designed between the two seals to enhance the water sealing function and reduce the risk of water entering the vehicle when washing it with high pressure water.

[0063] 3. The fastening ability is enhanced by the multiple layers of adhesive, including the clamping slot 21, clamping claw 22, and shielding part 80, and the assembly is simple.

[0064] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
