Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a corner structure for a window sealing strip and a window. Background Technology

[0002] In modern automotive manufacturing, window seals are a key component of the vehicle's sealing system. Their design and performance have a crucial impact on the vehicle's sealing performance, comfort, and lifespan. The primary function of window seals is to prevent rainwater and dust from entering the vehicle, while also reducing vibration and noise between the window and the body, thus ensuring a superior driving experience. The corner structure of the window seal is an important part of the automotive sealing system. Its main function is to ensure the integrity of the seal at the window corners, preventing rainwater and dust from entering the vehicle through gaps at the corners, and also reducing vibration and noise between the window and the body, further enhancing the driving experience. For example, Chinese utility model patent CN214564551U discloses a corner joint mechanism for a car window sealing strip, including a vertical sealing strip and a horizontal sealing strip connected together. The vertical sealing strip has a first blocking lip extending outward from the corner, and the horizontal sealing strip has a second blocking lip extending inward from the corner. The first and second blocking lips each include at least two layers of parallel baffles, with a receiving groove between the two layers of baffles. This corner joint mechanism improves the sealing performance at the corners of car window frames. However, the corner joint design often fails to adequately consider the stress at the corner during glass lifting. The structural strength of the corner itself is insufficient. During glass lifting, the sealing strip is subjected to multiple forces, including friction from the glass, traction from the lifter, and its own weight. The combined effect of these forces easily leads to stress concentration at the corner, causing breakage. Furthermore, the uneven stress distribution at the corner increases the risk of breakage. Utility Model Content

[0003] The technical problem to be solved by this application is to provide a corner structure for a car window sealing strip and a car window. The corner structure effectively disperses the stress generated during the raising and lowering of the car window glass by adding a through groove structure to prevent breakage, thereby avoiding stress concentration and damage to the corner structure and enhancing the stability of the corner structure.

[0004] The technical solution adopted in this application is: a corner structure for a vehicle window sealing strip, including a first sealing strip and a second sealing strip. The first sealing strip is provided with a first lip that is adapted to the vehicle window glass. The first lip is used to fit the top of the vehicle window glass. The second sealing strip is connected to the first sealing strip. A through groove is provided on the side of the second sealing strip. The through groove is used to prevent the corner structure from breaking.

[0005] Compared with the prior art, the advantages of this application are that the first and second sealing strips can be fixed by adhesive bonding, which is simple and reliable. The first sealing strip is designed with a first lip to ensure the sealing of the top of the window glass, forming a preliminary sealing effect and preventing rainwater from entering the car from the top of the window, thus enhancing the sealing performance of the top of the window. The second sealing strip of this application is equipped with a through groove for preventing breakage. The design of the through groove plays a role in buffering and stress dispersion in structure. When the window glass is raised and lowered, the sealing strip is subjected to multiple forces such as friction from the glass, traction from the window regulator, and its own weight. The through groove can effectively disperse these forces and avoid stress concentration, thereby preventing the corner structure from breaking during the glass raising and lowering process. This allows the sealing strip to maintain good structural integrity during long-term use, especially when the window is frequently raised and lowered, reducing the risk of sealing failure due to breakage and other problems, and extending the service life of the sealing strip. At the same time, stable sealing performance also helps to reduce noise and vibration inside the car, further improving the driving and riding quality of the vehicle.

[0006] In some embodiments of this application, the second sealing strip has a corner, the end of which engages with the end of the first sealing strip. In this application, the corner design allows the second sealing strip to fit snugly against the corner of the window, forming a seamless sealing structure after engagement with the end of the first sealing strip. This effectively prevents rainwater, dust, and other contaminants from entering the vehicle through gaps at the corner, significantly improving the sealing performance at the window corner and further enhancing the overall sealing effect of the window sealing system.

[0007] In some embodiments of this application, the through groove is disposed on the side wall of the corner. In this application, the corner is a weak point of the sealing strip and is easily subjected to greater stress during the raising and lowering of the car window. The through groove disposed on the side wall of the corner can effectively disperse the stress at the corner, optimize the stress distribution, avoid fracture caused by stress concentration, significantly enhance the structural stability of the corner, and improve the reliability of the sealing strip during the raising and lowering of the car window. By providing a through groove on the side wall of the corner, the corner can be reinforced and stress dispersed without adding additional structural components, thus extending the service life of the sealing strip.

[0008] In some embodiments of this application, the through groove is a triangular structure. In this application, the through groove is designed as a triangular structure, which has high stability and strength, effectively dispersing and bearing stress. The three sides of the triangular through groove can disperse stress in different directions, avoiding stress concentration at a single point or line, significantly reducing the stress level at the corners, thereby improving the structural stability of the sealing strip. During the raising and lowering of the car window glass, the corner structure of the sealing strip is subjected to various forces; the triangular through groove can effectively buffer these forces, reducing the risk of breakage and increasing the service life of the sealing strip.

[0009] In some embodiments of this application, one side of the through groove is parallel to the side of the second sealing strip. In this application, the parallel design allows the through groove and the second sealing strip to work together better, avoiding stress concentration and significantly enhancing the structural stability at the corner of the sealing strip. During the raising and lowering of the car window, the sealing strip is subjected to various forces; the parallel design can effectively buffer these forces, reduce the risk of breakage, and improve the performance of the entire sealing strip corner structure.

[0010] In some embodiments of this application, the second sealing strip is provided with a second lip that adapts to the vehicle window glass, and the second lip is used to fit against the surface of the vehicle window glass. In this application, the second sealing strip is designed with a second lip, which further enhances the fit between the sealing strip and the vehicle window glass, providing more comprehensive sealing protection. Both the first lip and the second lip are adapted to the vehicle window glass and can fit tightly against different parts of the vehicle window glass, ensuring the reliability of the seal. During the raising and lowering of the vehicle window, the second lip can effectively buffer the friction and shear force between the vehicle window glass and the sealing strip, reducing the risk of breakage.

[0011] In some embodiments of this application, the second lip is provided with a water guide, which is used to drain water accumulated between the second lip and the window glass. In this application, the water guide can effectively guide the water out, preventing rainwater from accumulating between the sealing strip and the window glass, avoiding leakage problems caused by rainwater accumulation. This not only improves the service life of the sealing strip, but also avoids seal failure and damage to the window glass caused by water accumulation, further improving the sealing performance and service life of the window. During the window raising and lowering process, the water guide can also further buffer the friction and shear force between the window glass and the sealing strip, reducing the risk of breakage.

[0012] In some embodiments of this application, the second sealing strip is provided with a third lip, which is used to conform to the surface of the vehicle window glass. In this application, the third lip, like the second lip, is a structure that contacts the surface of the vehicle window glass, further enhancing the sealing performance of the side of the vehicle window glass. The multi-lip design forms a multi-layered sealing structure, creating a more reliable sealing system that can effectively prevent rainwater, dust, etc., from entering the vehicle from different directions. Furthermore, the addition of the third lip further improves the stability of the entire sealing strip structure. During the raising and lowering of the vehicle window, the third lip can effectively buffer the friction and shear force between the vehicle window glass and the sealing strip, reducing the risk of breakage.

[0013] In some embodiments of this application, a cavity is formed between the second lip and the third lip, the cavity communicating with the water guide. The side of the cavity is configured as an open structure, which communicates with the side of the second sealing strip. In this application, the cavity is designed to communicate with the water guide. The existence of the cavity provides a temporary storage and guiding space for water flow. Water accumulated between the second lip and the window glass enters the cavity through the water guide. The cavity acts as a drainage channel, allowing water to drain out, effectively preventing water accumulation between the second lip and the window glass. This avoids sealing failure and damage to the window glass caused by water accumulation. The open structure provides a direct connection between the cavity and the external drainage system, effectively guiding the water flow inside the cavity to the outside, preventing water accumulation inside the cavity, ensuring smooth water drainage, and further improving water guiding efficiency. The open structure design also disperses stress to a certain extent, reducing stress concentration and extending the service life of the sealing strip.

[0014] This application may also provide another technical solution: a vehicle window including the corner structure of any of the aforementioned vehicle window sealing strips. In this application, the vehicle window integrates an optimized corner structure for the sealing strip, which reduces the risk of sealing failure due to stress concentration, enhances the structural stability of the entire vehicle window system, and enables the vehicle window to maintain stable structural performance during the raising and lowering of the window, reducing the risk of breakage due to stress concentration.

[0019] The present application will now be described in detail with reference to the accompanying drawings.

[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] An example of a corner structure for a car window sealing strip, as shown in Embodiment 1. Figures 1 to 3 As shown: This includes a first sealing strip 1 and a second sealing strip 2. The first sealing strip 1 has a first lip 11 that fits the top of the window glass 3. The first lip 11 is used to fit the top of the window glass 3. The first sealing strip 1 and the second sealing strip 2 can be fixed by adhesive, which is simple and reliable. The first lip 11 of the first sealing strip 1 ensures the sealing of the top of the window glass 3, forming a preliminary sealing effect and preventing rainwater from entering the vehicle from the top of the window, thus enhancing the sealing performance of the top of the window. The second sealing strip 2 is connected to the first sealing strip 1. A through groove 21 is provided on the side of the second sealing strip 2. The through groove 21 is used to prevent the corner structure from breaking. The design of the through groove 21 is structurally... The through groove 21 plays a role in buffering and stress dispersion. When the car window glass 3 is raised or lowered, the sealing strip is subjected to multiple forces, such as friction from the glass, traction from the regulator, and its own weight. The through groove 21 can effectively disperse these forces and avoid stress concentration, thereby preventing the corner structure from breaking during the glass raising and lowering process. This allows the sealing strip to maintain good structural integrity during long-term use, especially when the car window is frequently raised and lowered, reducing the risk of sealing failure due to breakage and other problems, and extending the service life of the sealing strip. At the same time, stable sealing performance also helps to reduce noise and vibration inside the car, further improving the driving and riding quality of the vehicle.

[0022] More specifically, the second sealing strip 2 is provided with a corner 22, the end of which is joined with the end of the first sealing strip 1. The corner 22 design allows the second sealing strip 2 to fit tightly against the corner of the window. After joining with the end of the first sealing strip 1, a seamless sealing structure is formed, which effectively prevents rainwater, dust and other substances from entering the car through the gap at the corner, significantly improves the sealing performance at the corner of the window, and further enhances the sealing effect of the entire window sealing system.

[0023] More specifically, the through groove 21 is set on the side wall of the corner 22. The corner 22 is a weak point of the sealing strip and is prone to large stress during the raising and lowering of the car window glass 3. The through groove 21 is set on the side wall of the corner 22, which can effectively disperse the stress at the corner 22, optimize the stress distribution, avoid the fracture caused by stress concentration, significantly enhance the structural stability of the corner 22, and improve the reliability of the sealing strip during the raising and lowering of the car window. By setting the through groove 21 on the side wall of the corner 22, the corner 22 can be reinforced and stress dispersed without adding additional structural components, thus extending the service life of the sealing strip.

[0024] More specifically, the through groove 21 has a triangular structure. The triangular structure has high stability and strength, and can effectively disperse and bear stress. The three sides of the triangular through groove 21 can disperse the stress in different directions, avoiding stress concentration at a point or a line, significantly reducing the stress level at the corner 22, thereby improving the structural stability of the sealing strip. During the lifting and lowering of the car window glass 3, the corner structure of the sealing strip will be subjected to various forces. The triangular through groove 21 can effectively buffer these forces, reduce the risk of breakage, and improve the service life of the sealing strip.

[0025] More specifically, one side of the through groove 21 is parallel to the side of the second sealing strip 2. The parallel design allows the through groove 21 and the second sealing strip 2 to work together better, avoid stress concentration, and thus significantly enhance the structural stability at the corner 22 of the sealing strip. During the raising and lowering of the window, the sealing strip will be subjected to various forces. The parallel design can effectively buffer these forces, reduce the risk of breakage, and improve the performance of the entire sealing strip corner structure.

[0026] Example 2, as Figures 2 to 3As shown, the second sealing strip 2 is provided with a second lip 23 that is adapted to the window glass 3. The second lip 23 is used to fit the surface of the window glass 3. The second sealing strip 2 is designed with a second lip 23 to further enhance the fit between the sealing strip and the window glass 3 and provide more comprehensive sealing protection. Both the first lip 11 and the second lip 23 are adapted to the window glass 3 and can fit tightly to different parts of the window glass 3 to ensure the reliability of the seal. During the raising and lowering of the window, the second lip 23 can effectively buffer the friction and shear force between the window glass 3 and the sealing strip to reduce the risk of breakage.

[0027] More specifically, the second lip 23 is provided with a water guide 231, which is used to drain water accumulated between the second lip 23 and the window glass 3. The water guide 231 can effectively guide the water out, prevent rainwater from accumulating between the sealing strip and the window glass 3, and avoid leakage problems caused by rainwater accumulation. This not only improves the service life of the sealing strip, but also avoids sealing failure and damage to the window glass 3 caused by water accumulation, further improving the sealing performance and service life of the window. During the window raising and lowering process, the water guide 231 can also further buffer the friction and shear force between the window glass 3 and the sealing strip, reducing the risk of breakage.

[0028] More specifically, the second sealing strip 2 is provided with a third lip 24, which is used to fit the surface of the window glass 3. Like the second lip 23, the third lip 24 is a structure that contacts the surface of the window glass 3, further enhancing the sealing performance of the side of the window glass 3. The multi-lip design forms a multi-layer sealing structure, creating a more reliable sealing system that can effectively prevent rainwater, dust, etc. from entering the vehicle from different directions. Furthermore, the addition of the third lip 24 further improves the stability of the entire sealing strip structure. During the raising and lowering of the window, the third lip 24 can effectively buffer the friction and shear force between the window glass 3 and the sealing strip, reducing the risk of breakage.

[0029] More specifically, a cavity 25 is formed between the second lip 23 and the third lip 24. The cavity 25 communicates with the water inlet 231. The side of the cavity 25 is configured as an open structure, which communicates with the side of the second sealing strip 2. The cavity 25 provides a temporary storage and guiding space for water flow. Water accumulated between the second lip 23 and the window glass 3 enters the cavity 25 through the water inlet 231. The cavity 25 serves as a drainage channel, allowing accumulated water to drain out effectively. To prevent water from accumulating between the second lip 23 and the window glass 3, thus avoiding seal failure and damage to the window glass 3 due to water accumulation, an opening structure is designed to provide a direct connection between the cavity 25 and the external drainage system. The opening structure can effectively guide the water flow inside the cavity 25 to the outside, preventing water from accumulating inside the cavity 25 and ensuring smooth water drainage, further improving water guiding efficiency. The design of the opening structure also disperses stress to a certain extent, reducing stress concentration and extending the service life of the sealing strip.
