Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a vehicle trim panel sealing assembly and a vehicle. Background Technology

[0002] In automotive design, the B-pillar is a crucial structural component on the side of a vehicle. It not only supports the body but also plays a key transitional role between the exterior and interior. The B-pillar sealing strip and trim panel, as important parts of the vehicle, perform multiple functions including sealing, waterproofing, dustproofing, noise reduction, and decoration. During driving, vehicles are affected by external environmental factors such as rain, dust, and wind noise. The connection structure between the B-pillar sealing strip and trim panel needs to ensure good sealing to prevent rainwater and dust from entering the vehicle, while simultaneously reducing wind noise to improve the comfort of passengers. For example, Chinese invention patent CN101879855A discloses a sealing strip for automotive door and window frames, comprising a solid body and a foamed lip connected thereto. The solid body has a cross-section consisting of a vertical segment and an upper and lower horizontal segment connected thereto. The upper horizontal segment connects to the upper part of the vertical segment and extends to the left, while the lower horizontal segment connects to the lower part of the vertical segment and extends to the right. The length of the lower horizontal segment is greater than the length of the upper horizontal segment. The foamed lip has a crescent-shaped cross-section, with its right side connected to the left side of the upper horizontal segment of the solid body's cross-section. This technical solution achieves a tight connection between the sealing strip and the trim panel by applying adhesive sealant to the bottom of the solid body, combined with the special structural design of the solid body and the foamed lip, thus improving sealing performance. However, the sealing strip may shift or deform during installation due to external forces, requiring very precise positioning to ensure a tight fit with the trim panel, thus demanding high installation accuracy. Utility Model Content

[0003] The technical problem to be solved by this application is to provide a vehicle trim panel sealing assembly and a vehicle. The trim panel sealing assembly, through the cooperation of a first positioning protrusion and a positioning groove, not only improves structural stability, but also simplifies the installation process and improves installation efficiency and quality.

[0004] The technical solution adopted in this application is as follows: a vehicle trim panel sealing assembly, including a trim panel and a sealing strip, wherein the inner wall of the trim panel is provided with a first positioning protrusion, and the sealing strip is provided with a positioning groove adapted to the first positioning protrusion, wherein the first positioning protrusion is connected to the positioning groove so that the trim panel is positioned and connected to the sealing strip.

[0005] Compared with the prior art, the advantages of this application are that a first positioning protrusion is added to the inner wall of the trim panel, and a positioning groove adapted to the first positioning protrusion is added to the sealing strip. This allows the trim panel and the sealing strip to achieve precise positioning and connection through the cooperation of the first positioning protrusion and the positioning groove. During installation, the positioning groove of the sealing strip is aligned with the first positioning protrusion of the trim panel, and the two are connected by plugging. The positioning is simple and accurate. Through the connection of the first positioning protrusion and the positioning groove, a mechanical limiting structure is formed between the sealing strip and the trim panel. This not only provides a stable connection but also resists vibration and impact during vehicle operation, ensuring that the sealing strip and the trim panel will not shift or fall off relative to each other, thereby improving the service life and reliability of the trim panel assembly. During installation, the cooperation of the first positioning protrusion and the positioning groove provides clear installation position guidance for the trim panel, enabling the sealing strip to be installed quickly and accurately. This avoids problems such as poor sealing caused by inaccurate installation position, reduces installation difficulty, and improves installation efficiency and quality.

[0006] In some embodiments of this application, the sealing strip is provided with a second positioning protrusion adapted to the top of the trim panel. The second positioning protrusion abuts against the top of the trim panel to position and connect the trim panel to the sealing strip. In this application, the second positioning protrusion of the sealing strip is aligned with the top of the trim panel, and the two are connected by abutting. The connection method is simple and quick, and it can ensure the positional accuracy between the sealing strip and the top of the trim panel, making the installation process simpler and faster. Through the abutment between the second positioning protrusion and the top of the trim panel, the fit between the sealing strip and the trim panel is tighter, which can effectively prevent the intrusion of rainwater, dust and wind noise. The mechanical limiting structure can provide a stable connection, resist vibration and impact during vehicle operation, and ensure that the sealing strip will not loosen or fall off during long-term use.

[0007] In some embodiments of this application, at least two first positioning protrusions are spaced apart, and at least two of the first positioning protrusions are located within the same positioning groove. In this application, the cooperation of multiple positioning protrusions with a positioning groove achieves multi-point positioning and connection between the sealing strip and the trim panel. The spaced distribution of the first positioning protrusions can distribute the force, improve the uniformity and stability of the connection, and at the same time, the spaced first positioning protrusions can provide multiple contact points, enhancing the tightness of the fit between the sealing strip and the trim panel.

[0008] In some embodiments of this application, the positioning groove and the second positioning protrusion are both disposed in the molding area of ​​the sealing strip. In this application, the molding area refers to the area where the sealing strip is formed by molding during the production process. In this area, the shape and structure of the sealing strip can be realized through the precise design of the mold. During the production process of the sealing strip, the positioning groove and the second positioning protrusion are formed in the molding area by molding. The positioning groove and the second positioning protrusion are formed in one step by molding, ensuring the shape and dimensional accuracy of the positioning groove and the second positioning protrusion, thereby improving the connection accuracy between the sealing strip and the decorative panel.

[0009] In some embodiments of this application, the second positioning protrusion is a block-shaped protrusion with a beveled bottom, creating an inverted structure. In this application, the second positioning protrusion is designed as a block structure, possessing a large contact area and high structural strength, providing stable support and positioning. The beveled bottom of the second positioning protrusion, forming an inverted structure, allows it to more easily enter the predetermined position when in contact with the top of the trim panel, guided by the bevel, and provides an additional locking effect after installation, enhancing the stability of the connection.

[0010] In some embodiments of this application, multiple sets of the first positioning protrusions are provided, and multiple positioning grooves are provided corresponding to the first positioning protrusions. In this application, multiple sets of first positioning protrusions are provided on the inner wall of the trim panel, and each set of first positioning protrusions may include at least one first positioning protrusion. Through the cooperation of multiple sets of positioning protrusions and multiple positioning grooves, multi-point positioning and connection between the sealing strip and the trim panel are achieved, thereby improving the reliability of the connection.

[0011] In some embodiments of this application, multiple second positioning protrusions are provided. In this application, the spaced distribution of multiple second positioning protrusions can provide a stable connection, resisting vibration and impact during vehicle operation. This multi-point positioning method can evenly distribute the force, ensuring that the sealing strip will not loosen or fall off during long-term use. The tight fit between the multiple second positioning protrusions and the top of the trim panel can ensure a tight fit between the sealing strip and the trim panel, thereby improving the sealing performance.

[0012] In some embodiments of this application, the sealing strip is provided with a first lip, which is used to fit against the top of the trim panel. In this application, the first lip is designed to be made of a material with a certain degree of elasticity and flexibility, which can fit tightly against the top of the trim panel during installation. Even if there are minor unevenness or deformation on the surface of the trim panel, it can maintain good sealing performance, effectively preventing the intrusion of rainwater, dust and wind noise, while also providing a certain degree of sound insulation and heat insulation.

[0013] In some embodiments of this application, the sealing strip is provided with a second lip, which is used to abut against the inner wall of the trim panel. In this application, the second lip is designed to be made of a material with a certain degree of elasticity and flexibility, which can abut against the inner wall of the trim panel during installation. Even if there are minor unevenness or deformations on the inner wall of the trim panel, it can maintain good sealing performance, further preventing the intrusion of rainwater, dust and wind noise, while also further improving the sound insulation and heat insulation effects.

[0014] This application may also provide a vehicle including any of the aforementioned vehicle trim panel sealing assemblies. In this application, the trim panel sealing assembly, which includes the aforementioned trim panel and sealing strip, is mainly applied to the B-pillar area of ​​the vehicle. Through the first positioning protrusion of the trim panel and the positioning groove of the sealing strip, the trim panel and the sealing strip are precisely positioned and connected, which not only improves structural stability but also simplifies the installation process and improves installation efficiency and quality.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] A vehicle trim panel sealing assembly, embodiment one as follows Figures 1 to 3 As shown: a decorative panel 1 and a sealing strip 2. The inner wall of the decorative panel 1 is provided with a first positioning protrusion 11, and the sealing strip 2 is provided with a positioning groove 21 that matches the first positioning protrusion 11. The decorative panel 1 and the sealing strip 2 can achieve precise positioning and connection through the cooperation of the first positioning protrusion 11 and the positioning groove 21. During installation, the positioning groove 21 of the sealing strip 2 is aligned with the first positioning protrusion 11 of the decorative panel 1, and the two are connected by plugging. The positioning is simple and accurate. Through the connection of the first positioning protrusion 11 and the positioning groove 21, a seal is formed between the sealing strip 2 and the decorative panel 1. A mechanical limiting structure is provided, which not only provides a stable connection but also resists vibration and impact during vehicle operation, ensuring that the sealing strip 2 and the trim panel 1 will not shift or fall off relative to each other. This improves the service life and reliability of the trim panel sealing assembly. During installation, the cooperation between the first positioning protrusion 11 and the positioning groove 21 provides clear installation position guidance for the trim panel 1, enabling the sealing strip 2 to be installed quickly and accurately. This avoids problems such as poor sealing caused by inaccurate installation position, reduces installation difficulty, and improves installation efficiency and quality. It should be noted that the orientation described in this application is based on the accompanying drawings and does not imply the actual orientation of the product in use; this will not be elaborated further.

[0022] More specifically, the sealing strip 2 is provided with a second positioning protrusion 22 that is adapted to the top of the trim panel 1. The second positioning protrusion 22 abuts against the top of the trim panel 1 to position the trim panel 1 and connect the sealing strip 2. The second positioning protrusion 22 of the sealing strip 2 is aligned with the top of the trim panel 1, and the two are connected by abutting. The connection method is simple and quick, and can ensure the positional accuracy between the sealing strip 2 and the top of the trim panel 1, making the installation process simpler and faster. Through the abutting between the second positioning protrusion 22 and the top of the trim panel 1, the sealing strip 2 and the trim panel 1 fit more tightly, which can effectively prevent the intrusion of rainwater, dust and wind noise. The mechanical limiting structure can provide a stable connection, resist the vibration and impact during vehicle driving, and ensure that the sealing strip 2 will not loosen or fall off during long-term use.

[0023] Example 2, as Figures 2 to 4 As shown, there are at least two first positioning protrusions 11 spaced apart, and at least two first positioning protrusions 11 are located in the same positioning groove 21. Through the cooperation of multiple positioning protrusions and one positioning groove 21, multi-point positioning and connection between the sealing strip 2 and the trim panel 1 are realized. The spaced distribution of the first positioning protrusions 11 can distribute the force and improve the uniformity and stability of the connection. At the same time, the spaced distribution of the first positioning protrusions 11 can provide multiple contact points to enhance the tightness of the fit between the sealing strip 2 and the trim panel 1.

[0024] More specifically, the positioning groove 21 and the second positioning protrusion 22 are both located in the molding area of ​​the sealing strip 2. The molding area refers to the area where the sealing strip 2 is formed by molding process during production. In this area, the shape and structure of the sealing strip 2 can be realized through the precise design of the mold. During the production of the sealing strip 2, the positioning groove 21 and the second positioning protrusion 22 are formed in the molding area by molding process. The positioning groove 21 and the second positioning protrusion 22 are formed in one step by molding process, ensuring the shape and size accuracy of the positioning groove 21 and the second positioning protrusion 22, thereby improving the connection accuracy between the sealing strip 2 and the trim panel 1.

[0025] More specifically, the second positioning protrusion 22 is a block-shaped protrusion with a sloping bottom, so that the second positioning protrusion 22 has an inverted structure. The block-shaped structure of the second positioning protrusion 22 has a large contact area and high structural strength, which can provide stable support and positioning. The sloping bottom of the second positioning protrusion 22 forms an inverted structure, which allows the second positioning protrusion 22 to enter the predetermined position more easily through the guiding effect of the sloping surface when it contacts the top of the trim panel 1, and provides an additional locking effect after installation, enhancing the stability of the connection.

[0026] More specifically, multiple sets of first positioning protrusions 11 are provided, and multiple positioning grooves 21 are provided corresponding to the first positioning protrusions 11. Multiple sets of first positioning protrusions 11 are provided on the inner wall of the trim panel 1. Each set of first positioning protrusions 11 may include at least one first positioning protrusion 11. Through the cooperation of multiple sets of positioning protrusions and multiple positioning grooves 21, multi-point positioning and connection between the sealing strip 2 and the trim panel 1 are realized, thereby improving the reliability of the connection.

[0027] More specifically, multiple second positioning protrusions 22 are provided. The spaced distribution of multiple second positioning protrusions 22 can provide a stable connection and resist vibration and impact during vehicle operation. This multi-point positioning method can evenly distribute the force and ensure that the sealing strip 2 will not loosen or fall off during long-term use. The tight fit between multiple second positioning protrusions 22 and the top of the trim panel 1 can ensure a tight fit between the sealing strip 2 and the trim panel 1, thereby improving the sealing performance.

[0028] More specifically, the sealing strip 2 is provided with a first lip 23, which is used to fit against the top of the trim panel 1. In this application, the first lip 23 is designed to be made of a material with a certain degree of elasticity and flexibility, which can fit tightly against the top of the trim panel 1 during installation. Even if there are minor unevenness or deformation on the surface of the trim panel 1, it can maintain good sealing performance, effectively prevent the intrusion of rainwater, dust and wind noise, and also provide a certain degree of sound insulation and heat insulation.

[0029] More specifically, the sealing strip 2 is provided with a second lip 24, which is used to abut against the inner wall of the trim panel 1. The second lip 24 is designed with a certain degree of elasticity and flexibility, which can abut against the inner wall of the trim panel 1 during installation. Even if there are minor unevenness or deformations in the inner wall of the trim panel 1, it can maintain good sealing performance, further preventing the intrusion of rainwater, dust and wind noise, and also further improving the sound insulation and heat insulation effect.
