Description

Technical Field

[0001] This utility model relates to the technical field of automotive door corner window assemblies, and in particular to a frameless flush door corner window assembly. Background Technology

[0002] In the design of frameless vehicles, the matching methods between fixed and movable glass in the doors are mainly divided into two categories: flush and non-flush. Among them, flush doors eliminate the protruding feature of the guide rail on the outside of the glass, making the transition between the fixed and movable glass smoother, with a strong visual unity, which can significantly enhance the overall premium feel of the vehicle. This has become a design solution that mainstream OEMs are currently promoting.

[0003] Flush corner windows are a core component of flush doors, such as Figure 4-5 As shown, it mainly consists of a fixed glass 1, a guide rail 3, a sealing strip 4, adhesive, and double-sided tape 13. The connection relationship and function of each component are as follows: the guide rail 3 provides fixation and support for the sealing strip 4 on the one hand, and guidance and support for the movable glass 7 on the other hand; the core function of the sealing strip 4 is to cover the gap between the fixed glass 1 and the movable glass 7 and to achieve a seal with the movable glass 7; after the sealing strip 4 and the guide rail 3 are assembled, they are connected to the fixed glass 1 by adhesive, and the upper corner area is additionally bonded with double-sided tape 13.

[0004] In the above-mentioned flush corner window structure, the matching method between the sealing strip 4 and the fixed glass 1 is as follows: Figure 4-5 As shown, the extruded section of the sealing strip 4 has a small lip 14 structure and is designed to be interference-fitted with the fixed glass 1 (a→b), thereby ensuring a consistent appearance and no obvious gaps; as Figure 6 As shown, in the upper corner section, in the rounded corner area b→c of the fixed glass 1, the corner of the sealing strip 4 has a small lip 14 structure that interferes with the fixed glass 1 to ensure a seamless appearance in this area; on the inner side of the fixed glass 1, the corner of the sealing strip 4 is bonded to the fixed glass 1 with double-sided tape 13, and at the same time, in the c→d area, the corner of the sealing strip 4 also has a small lip 14 that interferes with the fixed glass 1 to ensure a seamless appearance. Figure 7-8 As shown.

[0005] However, the above structure has the following defects: 1. Weak structural strength: When the movable glass 7 of the car door is opened, the lip that contacts the movable glass 7 is not pressed and is in a free state. At this time, applying a small force to the outer sealing strip 4 can separate the lip of the sealing strip 4 from the fixed glass 1, forming a gap and exposing the internal structure. Figure 9 As shown; 2. Poor sealing ability: It uses a small lip 14 to overlap with the fixed glass 1, resulting in small reaction force and small contact surface, such as Figure 10-12As shown, when there is heavy rainfall or high-pressure washing, water will overflow the small lip and enter the inside. In the extrusion section, although water will overflow the sealing strip 4 and enter the interior, there is adhesive between the bright strip and the fixed glass 1, which can prevent water from entering. The water will be discharged outside the vehicle along the Z direction. In the corner section, the sealing strip and the fixed glass 1 are fixed with double-sided tape 13. There is no guide rail support on the back. When water overflows the small lip 14, in areas without tape, water directly overflows the lip and enters the inside; in areas with tape, the double-sided tape 13 cannot effectively prevent water from entering, and water will eventually overflow the tape and enter the inside. Therefore, the water-tightness of the product is poor in the corner section. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a frameless, flush-mounted car door corner window assembly, which replaces the traditional adhesive tape and glue bonding by integral injection molding of the edge, completely filling and fixing the assembly gap between the glass and the guide rail and sealing strip, and with the help of a primer to enhance the adhesion.

[0007] The technical solution adopted by this utility model to solve its technical problem is: to provide a frameless flush-mounted car door corner window assembly, including fixed glass, movable glass, guide rail and sealing strip installed inside the guide rail. The guide rail and sealing strip are connected to the fixed glass by an integrally injection-molded edge. The guide rail is used to fix and support the sealing strip and to support and guide the movable glass. The sealing strip is used to cover the gap between the fixed glass and the movable glass, while ensuring the seal between them.

[0008] As a supplement to the technical solution described in this utility model, the two sides of the edging are respectively bonded to the sealing strip and the fixed glass. A primer is applied to both the bonding surfaces of the sealing strip and the edging, as well as the bonding surfaces of the fixed glass and the edging. The edging is coated with a primer before injection molding to increase its adhesion. Therefore, when force is applied, existing solutions easily expose gaps and reveal the internal structure, but this utility model makes it difficult to create gaps between the edging, the fixed glass, and the sealing strip.

[0009] As a supplement to the technical solution described in this utility model, the guide rail is provided with an assembly groove for accommodating the edging and sealing strip, and the assembly groove is engaged with the sealing strip.

[0010] As a supplement to the technical solution described in this utility model, the assembly groove is provided with a slot along the length direction, and the sealing strip is provided with a snap-fit ​​protrusion that cooperates with the slot. The cross-section of the slot is an inverted T-shape.

[0011] As a supplement to the technical solution described in this utility model, the sealing strip has two inwardly curved lip structures, and one side of the movable glass is located between the two lip structures.

[0012] As a supplement to the technical solution described in this utility model, the edging is L-shaped in general, and the edging will partially surround the edge of the fixed glass.

[0013] As a supplement to the technical solution described in this utility model, the edging is made of TPE or PVC soft rubber material.

[0014] As a supplement to the technical solution described in this utility model, two brackets are provided along the length direction on the guide rail, and a second bracket is provided on the edge; the first bracket and the second bracket are used to provide fixing points between the product and the sheet metal; the first bracket is fixed to the guide rail by welding or screws.

[0015] Beneficial Effects: This utility model relates to a frameless, flush-mounted car door corner window assembly. It replaces traditional tape and adhesive bonding with an integrally injection-molded edging, completely filling the assembly gap between the fixed glass and the guide rail and sealing strip. Combined with a primer to enhance adhesion, the inverted T-shaped snap-fit ​​structure prevents sealing strip displacement, significantly improving the reliability of the car door seal. The shorter integral injection molding time required for this utility model, compared to the long adhesive curing time required for traditional methods, greatly shortens the product production cycle, increases production speed, and effectively meets the needs of large-scale mass production. Simultaneously, it reduces bonding processes, lowers human error, and improves product qualification rate. The L-shaped edging partially surrounds the edge of the fixed glass, and with the strong adhesion of the primer, the fixed glass, edging, and sealing strip form a fixed structure.

[0030] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0031] The present invention relates to a frameless, flush-mounted car door corner window assembly, such as... Figure 1-13 As shown, it includes a fixed glass 1, a movable glass 7, a guide rail 3, and a sealing strip 4 installed inside the guide rail 3. The guide rail 3 and the sealing strip 4 are connected to the fixed glass 1 by an integrally injection-molded edging 2. The guide rail 3 is used to fix and support the sealing strip 4 and to support and guide the movable glass 7. The sealing strip 4 is used to cover the gap between the fixed glass 1 and the movable glass 7, while ensuring a seal between them.

[0032] This utility model uses an integrally injection-molded edge banding 2 to replace the existing adhesive tape bonding scheme, and the edge banding 2 fills the gap between the sealing strip 4 and the fixed glass 1. Moreover, the integral injection molding of this utility model requires a shorter time, while the traditional method requires a long time for the adhesive to cure, which greatly shortens the product production cycle, increases the production pace, and effectively meets the needs of large-scale mass production. At the same time, it reduces the bonding process, reduces human operation error, and improves the product qualification rate.

[0033] The two sides of the edging 2 are respectively bonded to the sealing strip 4 and the fixed glass 1. To enhance the bonding reliability, a primer 12 is provided on the bonding surfaces of the sealing strip 4 and the edging 2, as well as on the bonding surfaces of the fixed glass 1 and the edging 2. The primer 12 is a silane or polyurethane primer with a coating thickness of 5-10 μm. Its function is to improve the surface energy of the bonding surfaces, promote the bonding between the edging material and the bonding surfaces, enhance the bonding force, and effectively prevent gaps from forming under external forces. The edging 2 is coated with a corresponding primer before injection molding to increase the bonding force of the edging. Therefore, when a force is applied, the existing solution will easily expose gaps and reveal the internal structure, but this utility model makes it difficult for gaps to form between the edging, the fixed glass, and the sealing strip.

[0034] As a structural description of the guide rail 3, the guide rail 3 is provided with an assembly groove 8 for accommodating the edging 2 and the sealing strip 4. The assembly groove 8 is engaged with the sealing strip 4. The guide rail 3 is a long strip structure.

[0035] As an explanation of the structure of the guide rail 3 engaging with the guide rail, the assembly groove 8 has a groove 9 opened along the length direction inside, and the sealing strip 4 is provided with a snap-fit ​​protrusion 10 that engages with the groove 9. The cross-section of the groove 9 is an inverted T-shape. The engagement of the groove 9 and the snap-fit ​​protrusion 10 can realize the limiting and fixing of the sealing strip 4, and prevent the sealing strip 4 from shifting or falling off during the sliding of the movable glass 7.

[0036] As a structural description of the sealing strip 4, the sealing strip 4 has two inwardly curved lip structures 11, and one side of the movable glass 7 is located between the two lip structures 11.

[0037] As a preferred embodiment of the edge banding 2, the edge banding 2 is L-shaped in general, and the edge banding 2 partially surrounds the edge of the fixed glass 1; the edge banding 2 is made of TPE or PVC soft rubber material, which has excellent flexibility, aging resistance and compatibility with glass, to ensure that the edge banding 2 is firmly bonded.

[0038] To secure the corner window assembly to the door sheet metal, two brackets 5 are provided along the length of the guide rail 3, and a bracket 6 is provided on the edging 2. The brackets 5 and 6 provide fixing points between the product and the sheet metal, ensuring the stability of the connection between the corner window assembly and the sheet metal, and facilitating later maintenance and disassembly. The brackets 5 are fixed to the guide rail 3 by welding or screws.

[0039] The fixed glass 1 is made of automotive-grade tempered glass or laminated glass, and its edges are beveled. The movable glass 7 is made of the same material as the fixed glass 1, and its edges and the mating surfaces of the lip structure 11 are polished to improve the smoothness of sliding.

[0040] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0041] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.
