Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a fixed window structure for a split interior and exterior trim guide rail cover. Background Technology

[0002] The guide rail structure of the front and rear door corner windows of a car directly affects the overall appearance, material cost, and ease of installation. Currently, there are three main solutions for fixed window structures:

[0003] Option 1: As Figure 7 As shown, the exterior guide rail cover 1 is separately connected to the guide rail body 19. The exterior guide rail cover 1 can be made of plastic or metal, but the interior 20 uses TPE or PVC plastic coating process. The visible area of ​​the interior 20 is made of rubber or plastic material, which cannot present a metallic texture and cannot meet the user's demand for a metallic texture in the interior and exterior. At the same time, the sealing reliability of the interior 20 is poor, and it is easy to loosen and make abnormal noises after long-term use.

[0004] Option 2: Figure 8 As shown, an integral aluminum alloy guide rail 21 is used. The aluminum alloy guide rail 21 is fixed to the corner window by injection molding or assembly. The injection molding uses soft rubber 4, which is commonly made of TPE or PVC soft rubber. The visible area is all metal. Although it can ensure the metallic texture, the use of the entire aluminum alloy guide rail 21 leads to a significant increase in material cost and a large overall weight, which does not conform to the trend of automotive lightweight development.

[0005] Option 3: As Figure 9 As shown, the guide rail frame 4 is made of metal or plastic. The guide rail position of the guide rail frame 4 is coated with soft rubber 4. The soft rubber 4 is preferably TPE soft rubber, which has a rubber-like appearance and poor texture. In addition, the sealing strip needs to be inserted from the side for installation, which is cumbersome, has low installation efficiency, and unstable sealing performance, which is prone to problems such as water leakage and abnormal noise.

[0006] Therefore, there is an urgent need for a fixed window structure that can ensure the metallic texture of visible areas inside and outside the window, while reducing material costs, simplifying the installation process, and preventing abnormal noises during use. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to provide a fixed window structure with a split inner and outer decorative guide rail cover plate, which overcomes the defects of the existing fixed window structure such as insufficient texture, high cost or inconvenient installation. Through the split inner and outer decorative guide rail cover plate structure, the synergistic optimization of metallic texture presentation, cost control, lightweight and convenient installation is achieved.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows: a fixed window structure for a split interior and exterior guide rail cover plate is provided, including an exterior guide rail cover plate, an interior guide rail cover plate, a guide rail frame, and glass. The guide rail frame and glass are connected and fixed by soft adhesive. Both the exterior guide rail cover plate and the interior guide rail cover plate are made of metal.

[0012] As a supplement to the technical solution described in this utility model, the soft rubber is injection molded, and the soft rubber is TPE soft rubber or PVC soft rubber.

[0013] As a supplement to the technical solution described in this utility model, the soft rubber is provided with an inner lip, the outer decorative guide rail cover plate overlaps with the inner lip to form a seal, and a gap is reserved between the outer decorative guide rail cover plate and the soft rubber.

[0014] As a supplement to the technical solution described in this utility model, both the exterior guide rail cover and the interior guide rail cover are made of aluminum alloy.

[0015] As a supplement to the technical solution described in this utility model, the guide rail frame is made of plastic material, preferably nylon material, and PA66 GF30 is the preferred nylon material.

[0016] As a supplement to the technical solution described in this utility model, the Y-direction buckle includes a male buckle and a female buckle. Multiple male buckles are evenly arranged along the length direction on the inner side of the outer guide rail cover plate, and female buckles corresponding one-to-one with the male buckles are provided on the guide rail frame.

[0017] Beneficial effects: This utility model relates to a fixed window structure for a split-type inner and outer decorative guide rail cover, which has the following advantages:

[0018] 1. Both the interior and exterior guide rail covers are made of aluminum alloy, allowing the visible areas to directly present a pure metallic texture, satisfying users' aesthetic needs; the guide rail frame is made of plastic materials such as PA66 GF30, replacing the traditional integrated aluminum alloy guide rail or metal frame, which greatly reduces material costs and reduces the overall weight of the fixed window, in line with the trend of automotive lightweighting.

[0019] 2. The exterior guide rail cover is quickly snapped into the guide rail frame via a Y-axis snap-fit ​​(male and female snap-fit ​​structure). The interior guide rail cover achieves precise positioning through a double snap-fit ​​between protrusion one and hook, and between limiting part and protrusion two, and is then secured with Y-axis screws. The installation process is simple, requires no complicated tools, and greatly improves assembly efficiency. The soft rubber and guide rail frame are integrally injection molded, avoiding the cumbersome operation of inserting the traditional sealing strip from the side.

[0020] 3. The interior guide rail cover is fixed by an L-shaped structure, double snap-fit ​​limit and Y-direction screw locking to prevent loosening; the soft rubber bonding part one and bonding part two are tightly bonded to the guide rail frame to fill the gap and effectively eliminate abnormal noises generated during pressing and driving.

[0021] 4. The soft inner lip is overlapped and sealed with the outer guide rail cover plate, and the gap is sealed through the soft adhesive part. The double sealing structure can effectively prevent rainwater and dust from entering, improve the waterproof and dustproof performance of the fixed window, and extend its service life.

[0022] 5. The exterior guide rail cover is flush with the glass, eliminating the traditional redundant outer lip structure, and leaving a reasonable gap with the soft rubber, resulting in a simple and smooth overall visual effect and enhancing the overall appearance quality of the vehicle.

[0033] 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.

[0034] The embodiments of this utility model relate to a fixed window structure for a split-type interior and exterior decorative guide rail cover, such as... Figure 1-6As shown, the system includes an exterior guide rail cover 1, an interior guide rail cover 2, a guide rail frame 3, and glass 5. The guide rail frame 3 and glass 5 are connected and fixed together by soft adhesive 4. The soft adhesive 4 is injection molded to form an integrated structure with the guide rail frame 3 and glass 5, ensuring a firm connection. Both the exterior guide rail cover 1 and the interior guide rail cover 2 are made of metal, preferably aluminum alloy, which ensures the metallic texture of the visible area while also meeting the requirements of lightweight design. The exterior guide rail cover 1 and guide rail frame 3 are detachably connected by a Y-shaped buckle, making installation convenient. The exterior guide rail cover 1 and glass 5 are flush, improving the cleanliness of the appearance. The interior guide rail cover 2 is limited to the guide rail frame 3 by a slot. The interior guide rail cover 2 is locked and fixed to the guide rail frame 3 by a Y-shaped screw 18, ensuring structural stability and preventing loosening.

[0035] As a structural description of the interior guide rail cover 2, the interior guide rail cover 2 includes a first plate 9 and a second plate 10 arranged in an L-shape. The L-shaped structure adapts to the installation space of the guide rail frame 3, taking into account both positioning stability and ease of installation. The first plate 9 has a protrusion 11 in the middle of its inner side. The lower side of the guide rail frame 3 has a hook 13 that cooperates with the protrusion 11. By engaging the protrusion 11 with the hook 13, the interior guide rail cover 2 is positioned on one side. The other side of the lower part of the guide rail frame 3 has a protrusion 17. The second plate 10 has a limiting part 15 in the shape of a "┓". The limiting part 15 engages with the protrusion 17 to position the interior guide rail cover 2 on the other side. The double locking and limiting ensures that the interior guide rail cover 2 is installed accurately and avoids displacement.

[0036] As a preferred structure to prevent abnormal noise, the soft adhesive 4 is provided with a first adhesive part 12 between the side of the guide rail frame 3 and the first plate 9. The first adhesive part 12 is bonded to the side of the guide rail frame 3 near the first plate 9 and is bonded to the inner side of the first plate 9. The guide rail frame 3 has a through hole 16 inside. The soft adhesive 4 passes through the through hole 16 and is provided with a second adhesive part 14 between the bottom of the guide rail frame 3 and the second plate 10. The second adhesive part 14 is bonded to the bottom of the guide rail frame 3 and is bonded to the upper side of the second plate 10. The double bonding design of the first adhesive part 12 and the second adhesive part 14 can effectively fill the gap between the interior guide rail cover 2 and the guide rail frame 3, avoid abnormal noise during pressing, and improve the structural sealing.

[0037] As a preferred embodiment of the soft rubber 4, the soft rubber 4 is injection molded and is made of TPE or PVC, possessing good elasticity, sealing performance, and aging resistance. The soft rubber 4 has an inner lip 6, and the outer guide rail cover 1 overlaps with the inner lip 6 to form a seal, with a pre-existing gap between the outer guide rail cover 1 and the soft rubber 4. The overlapping of the outer guide rail cover 1 and the inner lip 6 to form a sealing structure replaces the traditional method of directly attaching the outer lip to the surface of the outer guide rail cover 1, resulting in stronger sealing reliability and effectively preventing rainwater and dust from entering. Simultaneously, the pre-existing reasonable gap between the outer guide rail cover 1 and the soft rubber 4 avoids installation interference and makes the appearance simpler and smoother.

[0038] Regarding the material description of the guide rail frame 3, the guide rail frame 3 is made of plastic, preferably nylon, and more preferably PA66 GF30. This material has advantages such as high strength, high rigidity, and aging resistance. While ensuring structural strength, it significantly reduces costs compared to traditional metal frames, while also reducing overall weight, meeting the lightweight requirements of automobiles. PA66GF30 is a general designation for nylon 66PA66 reinforced with 30% glass fiber, mainly used in automotive parts, mechanical guards, and other fields with high requirements for rigidity, heat resistance, and dimensional stability. PA66 GF30 can be directly found on Baidu Encyclopedia and is an existing material.

[0039] As a preferred embodiment of the Y-direction snap fastener, the Y-direction snap fastener includes male snap fasteners 7 and female snap fasteners 8. Multiple male snap fasteners 7 are evenly arranged along the length direction on the inner side of the outer guide rail cover plate 1, and female snap fasteners 8 are provided on the guide rail frame 3, each corresponding to a male snap fastener 7. Through the snap-fit ​​cooperation of male snap fasteners 7 and female snap fasteners 8, the outer guide rail cover plate 1 and the guide rail frame 3 can be quickly positioned and fixed without the need for complex tools, greatly improving assembly efficiency. Multiple evenly arranged male snap fasteners 7 and female snap fasteners 8 can ensure balanced force distribution and avoid structural deformation caused by local stress concentration.

[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. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
