Description

Technical Field

[0001] This utility model relates to the field of vehicle window sealing technology, and in particular to a side sealing strip structure suitable for sealing two types of glass. Background Technology

[0002] While meeting front door safety regulations, this is a clever strategy that aims to deliver the best sound insulation performance precisely to the most important front-row positions with minimal cost and weight. Therefore, most existing frameless models use laminated glass in the front doors and single-layer glass in the rear doors, with the laminated glass in the front doors and the single-layer glass in the rear doors forming a whole with the side sealing strips.

[0003] The bubble-shaped sealing strips for the front and rear doors of most cars have the same structure, as shown in the instruction manual. Figure 1 and Figure 2 As shown, the bubble-shaped sealing strip structure satisfies the sealing requirements of a single-layer glass panel; however, when the laminated glass comes into contact with the bubble-shaped sealing strip structure, the end face of the laminated glass is beveled, and after the laminated glass abuts against the bubble-shaped sealing strip structure, it forms the shape shown in the attached instruction manual. Figure 3 The line contact state shown results in poor sealing between the laminated glass and the bubble sealing strip structure, making it prone to water leakage at the seal. Consequently, the existing bubble sealing strip structure is unable to meet the sealing requirements of both types of glass, leading to situations where the bubble sealing strip structure and the laminated glass are not properly sealed, resulting in air leakage, rain leakage, and sound insulation failure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a side sealing strip structure suitable for sealing both types of glass, thus solving the problem that existing bubble-type sealing strip structures are difficult to seal both single-layer and laminated glass.

[0005] To achieve the above objectives, the basic solution of this utility model is as follows: A side sealing strip structure suitable for sealing in two glass states, comprising a sealing strip body, the sealing strip body comprising: Several snap-fit ​​parts that engage with the sheet metal of the car door; Several abutting parts that abut against the sheet metal of the car door; A sealing bubble tube that can be tightly sealed against the end face of single-layer or laminated glass; The sealing body, snap-fit ​​part, abutment part and sealing bubble tube are all integrally formed on the sealing body.

[0006] The technical principle of this utility model is as follows: Through the snap-fit ​​and abutment parts, the sealing body can be stably installed onto the car door sheet metal, ensuring that the sealing bubble tube is accurately aligned with the end face of the single-layer or laminated glass. When the single-layer or laminated glass moves upward, the sealing bubble tube abuts and seals the end face of the single-layer or laminated glass, improving the sealing degree between the sealing bubble tube and the end face of the laminated glass, and reducing the probability of air leakage, rain leakage, and sound insulation failure between the sealing strip body and the laminated glass. Furthermore, the sealing bubble tube can simultaneously seal different single-layer or laminated glass, reducing design and application costs in frameless vehicles where the front doors generally use laminated glass and the rear doors use single-layer glass, where the side sealing strip structure can use the same sealing bubble tube.

[0007] Furthermore, the sealing bubble tube forms a contact portion at the point where it abuts the edge of the single-layer glass or laminated glass, and the contact portion forms a surface contact with the edge of the single-layer glass or laminated glass after abutting.

[0008] With the above settings, when the contact part abuts against the edge of the single-layer glass or laminated glass to form a surface contact, it can effectively increase the contact degree between the contact part and the edge of the laminated glass, realize the wrapping of the edge of the laminated glass, and improve the sealing performance of the contact part to the laminated glass.

[0009] Furthermore, the central angle R1 of the longitudinal section profile of the outer wall of the contact part is 22-26°.

[0010] With the above settings, compared to the 37° central angle of the outer longitudinal section profile of the contact part in the prior art bubble-type sealing strip structure, when the central angle of the outer longitudinal section profile of the contact part is 22-26°, the contact part is straighter and more easily, after the laminated glass rises, the contact part is pressed and deformed and then tensioned and adhered to the top of the laminated glass.

[0011] Furthermore, the maximum distance h1 between the midpoint of the inner wall of the contact part and the midpoint of the corner of the sealing body near the sealing bubble tube is 33-35mm.

[0012] With the above settings, compared to the prior art bubble-type sealing strip structure where the maximum distance between the contact part and the corner of the sealing body is mostly 31.7mm, when the maximum distance h1 between the contact part and the corner of the sealing body is 33-35mm, the contact part is closer to the top of the laminated glass. When the contact part comes into contact with the laminated glass, the contact part is more likely to deform, and the surface of the contact part is more likely to fit the top of the laminated glass, thus simultaneously satisfying the sealing of single-layer glass and laminated glass.

[0013] Furthermore, the wall thickness h2 at the midpoint of the longitudinal section of the contact part is 5-6 mm.

[0014] With the above settings, compared to the prior art bubble-type sealing strip structure where the wall thickness at the midpoint of the longitudinal section of the contact part is mostly 7.4mm, when the wall thickness h2 at the midpoint of the longitudinal section of the contact part is 5.7mm, the wall thickness of the contact part is thinner, which can further improve the deformation capability and thus fit and seal the top of the laminated glass and single-layer glass.

[0015] Furthermore, the vertical distance h3 between the midpoint of the outer wall of the longitudinal section of the contact part and the end of the longitudinal section of the sealing bubble tube near the single-layer glass or laminated glass is 11-13 mm.

[0016] With the above configuration, the contact part is located lower than the contact part in the bubble-type sealing strip structure of the prior art, making it easier to contact and abut against the top of the laminated glass and single-layer glass, thereby achieving precise and stable sealing of the laminated glass and single-layer glass.

[0017] Furthermore, a reinforcing rib is fixedly provided on the side of the sealing body near the contact portion, and the reinforcing rib is located at the end of the sealing body near the single-layer glass or laminated glass.

[0018] With the above configuration, the reinforcing ribs can stably support the structure at the corner of the sealing body near the single-layer glass or laminated glass, thereby improving the strength of the sealing body. Attached Figure Description

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] This embodiment is basically as follows: Figure 4 , Figure 5 and Figure 6 As shown, this utility model embodiment proposes a side sealing strip structure suitable for sealing in two glass states, including a sealing strip body, such as... Figure 4 As shown, the sealing strip body includes two sets of snap-fit ​​parts 20 that snap into the door sheet metal 70, two sets of abutting parts 30 that abut against the door sheet metal 70, and a sealing bubble tube 40 that can abut against the end face of the single-layer glass 50 or the laminated glass 60 for sealing. The snap-fit ​​parts 20, abutting parts 30 and sealing bubble tube 40 are all integrally formed on the sealing body 10.

[0028] At the same time, such as Figure 5 As shown, one of the snap-fit ​​parts 20 is located at the upper left end of the longitudinal section of the sealing body 10, and the other snap-fit ​​part 20 is located at the lower right end of the longitudinal section of the sealing body 10; one of the abutting parts 30 is located at the upper left side of the corner of the longitudinal section of the sealing body 10, and the other abutting part 30 is located at the upper right side of the corner of the longitudinal section of the sealing body 10.

[0029] like Figure 4 , Figure 5 and Figure 6 As shown, a contact portion 401 is formed at the point where the sealing bubble tube 40 abuts against the edge of the single-layer glass 50 or the laminated glass 60. After the contact portion 401 abuts against the edge of the single-layer glass 50 or the laminated glass 60, a surface contact is formed. The central angle R1 of the longitudinal section profile of the outer wall of the contact portion 401 is 24.5°. The maximum distance h1 between the midpoint of the inner wall of the contact portion 401 and the midpoint of the corner of the sealing body 10 near the sealing bubble tube 40 is 34.7 mm. The wall thickness h2 at the midpoint of the longitudinal section of the contact portion 401 is 5.7 mm.

[0030] At the same time, such as Figure 4 As shown, the vertical distance h3 between the midpoint of the outer wall of the longitudinal section of the contact part 401 and the end of the longitudinal section of the sealing bubble tube 40 near the single-layer glass 50 or the laminated glass 60 is 12.8 mm.

[0031] In addition, such as Figure 4 As shown, a reinforcing rib 101 is fixedly provided on the side of the sealing body 10 near the contact portion 401. The reinforcing rib 101 is located at the end of the sealing body 10 near the single-layer glass 50 or the laminated glass 60.

[0032] In this embodiment, a side sealing strip structure suitable for sealing two glass states is used such that when the single-layer glass 50 moves upward, as... Figure 5 As shown, the top side of the single-layer glass 50 is attached to the contact portion 401 of the sealing bubble tube 40. The contact portion 401 deforms and then fits tightly against the arc surface of the top side of the single-layer glass 50. The contact portion 401 can seal the lifting of the single-layer glass 50, and the single-layer glass 50 and the contact portion 401 achieve surface contact.

[0033] When the laminated glass 60 moves upward Figure 6 As shown, the top side of the laminated glass 60 is attached to the contact portion 401 of the sealing bubble tube 40. The contact portion 401 deforms and then tightly adheres to the inclined surface of the top side of the laminated glass 60. The contact portion 401 can stably adhere and seal the laminated glass 60 during lifting, and the laminated glass 60 and the contact portion 401 achieve surface contact. In this process, the maximum distance h4 between the contact part and the corner of the sealing body 10 in the background bubble-type sealing strip structure is mostly 31.7mm; while in this embodiment, the maximum distance h1 between the contact part 401 and the corner of the sealing body 10 is 34.7mm. The contact part 401 is closer to the top of the laminated glass 60. When the contact part 401 abuts against the laminated glass 60, the contact part 401 is more likely to deform, and thus the surface of the contact part 401 is more likely to adhere to the top of the laminated glass 60. At the same time, the wall thickness h5 at the midpoint of the longitudinal section of the contact part in the background bubble-type sealing strip structure is 7.4mm, while in this embodiment, the wall thickness h2 at the midpoint of the longitudinal section of the contact part 401 is 5.7mm. The thinner wall thickness of the contact part 401 can further improve the deformation capability. This allows the contact portion 401 to adhere and seal against the top of the laminated glass 60. Compared to the 37° central angle R2 of the longitudinal section profile of the contact portion in the prior art bubble-type sealing strip structure, the central angle R1 of the longitudinal section profile of the contact portion 401 in this embodiment is 24.5°. The contact portion 401 is straighter and more easily, after the laminated glass 60 rises, it is pressed and deformed, and then tensioned and adhered to the top of the laminated glass 60, improving the sealing performance between the laminated glass 60 and the contact portion 401. The contact portion h6 in the prior art bubble-type sealing strip structure is 15.6mm. In this embodiment, the contact portion 401 is lower and more easily contacts and abuts against the top of the laminated glass 60 and the single-layer glass 50, achieving a precise and stable seal for the laminated glass 60 and the single-layer glass 50.

[0034] As can be seen from the above, by changing the curvature, vertical position and thickness of the contact part 401, the fit between the contact part 401 and the top slope of the laminated glass 60 can be effectively improved, thereby forming a surface contact between the laminated glass 60 and the contact part 401; at the same time, a surface contact is also formed between the single-layer glass 50 and the contact part 401; the side sealing strip structure in this embodiment can be applied to the environment where the front door of the frameless vehicle uses laminated glass 60 and the rear door uses single-layer glass 50, which can improve the adaptability of the side sealing strip and improve the sealing performance of the window in the environment where the laminated glass 60 is installed, effectively reducing the probability of air leakage, rain leakage and sound insulation failure.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
