Description

Technical Field

[0001] This utility model relates to the field of vehicle door sealing technology, and in particular to a guide groove top strip and a vehicle door. Background Technology

[0002] In the modern automotive manufacturing industry, the top guide strip of the car window is a key component of the window sealing system, and its structural design and performance have a significant impact on the overall quality of the vehicle.

[0003] Traditional automotive guide channel top strip cross-section structures include components such as rubber coating, support, and decorative parts. With the evolution of automotive design towards fully flush glass designs, several problems have become apparent. First, regarding the step difference, because the cross-section layout must allow for the thickness of the decorative part, the thickness of the lip, and space for lip deformation, the step difference design is typically as high as 5mm or more. This not only affects the refinement and overall harmony of the car's appearance but also hinders the achievement of better aerodynamic performance and reduced wind noise. Second, from a manufacturing perspective, the guide channel uses a metal support part with rubber coating extrusion, while the decorative part requires metal extrusion or roll forming, followed by matching and assembly of the two. This complex and step-by-step production process increases the complexity and cost of the production flow and is prone to quality fluctuations during the connection between each process stage. Thirdly, regarding compatibility, the guide channel cross-section itself has production tolerances, and the trim part also has production tolerances. When the two are matched and assembled, new tolerances will accumulate, making it extremely difficult to match the guide channel top strip with other parts during the vehicle assembly process. It often requires a lot of manpower and time for debugging and correction, which seriously affects production efficiency and the stability of the overall vehicle assembly quality.

[0004] In summary, existing automotive guide channel top strip structures, when fully flush with the glass side, are insufficient to meet the increasingly demanding requirements of automotive design, production, and assembly. There is an urgent need for a novel design solution that can effectively address issues such as excessive step differences, complex processes, and difficult matching, achieving guide channel integration to meet customers' pursuit of near-zero step differences. Simultaneously, it should significantly improve manufacturability during production, greatly enhance conformability and matching during vehicle assembly, and fundamentally optimize costs, thereby driving progress and development in automotive manufacturing technology in the crucial area of ​​window sealing systems.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] like Figure 1 As shown, this embodiment provides a guide strip for buffering and sealing the closure of a vehicle window glass 200. The guide strip includes a support member 1 and a sealing buffer member 2. The support member 1 is made of stainless steel strip and includes a support part 11 and a decorative part 12. The decorative part 12 is disposed at one end of the support part 11. The support part 11 and the decorative part 12 are integrally formed. Compared with the existing guide strips where the decorative part 12 and the support part 11 are separately set, this reduces the step difference between the decorative part 12 and the glass 200. The step difference can reach within 2mm-4mm. The integrally formed design frame has higher strength and can provide better support for the glass. According to the design requirements, a stainless steel strip of appropriate specifications is selected and fed into a rolling equipment. Through a specific mold and rolling process, the steel strip is processed into a shape with a support part 11 and a decorative part 12. In addition, using a stainless steel strip as both the support part 11 and the decorative part 12 also reduces the material usage and processing costs. The support part 11 includes two spaced-apart support plates 111. The spacing between the two support plates 111 is designed according to the actual application scenario and the door structure. In this embodiment, the spacing is not limited, so as to ensure effective support for the glass 200 and provide suitable installation space for the subsequent sealing buffer 2 and other components. The decorative part 12 includes a decorative plate 121 and two connecting plates 122. One end of the two connecting plates 122 is connected to the opposite ends of the decorative plate 121, and the other end extends towards each other and is connected to the two support plates 111 respectively.

[0030] The sealing buffer 2 covers the surface of the support portion 11 and the surface of the decorative portion 12 facing the support portion 11. The sealing buffer 2 includes a main body portion 21 and an insertion portion 22. The main body portion 21 covers the outer surface of the support portion 11 and the outer surface of the decorative portion 12 facing the support portion 11. The insertion portion 22 is located between two support plates 111. The sealing buffer 2 is made of rubber material, which has good elasticity and sealing properties. After the support portion 1 is roll-formed, it is directly coated with rubber, eliminating the need for complex assembly processes. Compared with the traditional guide groove top strip manufacturing process, this reduces process steps, improves production efficiency, and lowers production costs. For example, the traditional guide groove top strip manufacturing process requires separate processing and assembly of the skeleton and the bright strip, while the process of this embodiment can simplify these steps into one step, improving production efficiency.

[0031] Preferably, the decorative panel 121 is in the shape of an arc strip. This shape design is not only aesthetically pleasing, but also effectively reduces air resistance and wind noise during vehicle operation.

[0032] Preferably, the decorative panel 121 and the connecting plate 122 are connected by a rounded surface 123. This transitional connection method can avoid stress concentration points and improve the overall strength and durability of the support.

[0033] Preferably, the insertion part 22 has a first slot for sealingly inserting with the sheet metal 100. The inner sidewall of the first slot is provided with a plurality of first lips 31 for sealingly abutting against the door sheet metal 100. In this embodiment, the insertion part 22 can closely fit the edge of the sheet metal 100 to form a reliable sealing connection, effectively preventing rainwater, dust and other impurities from entering the interior of the door. Three first lips 31 are provided on one side of the inner sidewall of the first slot, and the specific number can be adjusted according to the actual situation.

[0034] Preferably, the portion of the main body 21 on the same side as the sheet metal 100 and the glass 200 has a second slot. The second slot is used for a sealed insertion with the glass 200. The surface of the glass 200 relative to the interior of the vehicle is its inner surface, and the surface relative to the exterior of the vehicle is its outer surface. The surface of the glass 200 in the thickness direction is its side surface. The bottom wall of the second slot is provided with a second lip 32, which is used for a sealed abutment against the side surface of the glass 200. In this embodiment, the second slot can tightly wrap around the edge of the glass 200, providing good sealing and cushioning for the glass. The second lip 32 provided on the bottom wall of the second slot further enhances the cushioning and sealing function of the glass 200.

[0035] Preferably, the inner wall of the second slot is provided with a third lip 33, which is used to seal against the inner and outer surfaces of the glass 200. In this embodiment, the inner wall of the second slot is provided with third lips 33 on both sides. The third lip 33 that is close to the decorative part 12 is the outer lip, and there is one outer lip. The third lip 33 that is close to the sheet metal 100 is the inner lip, and there are two inner lips. In this embodiment, the first lip 31, the second lip 32, and the third lip 33 are all made of rubber, and their thickness and hardness have been optimized.

[0036] This embodiment also discloses a vehicle door, including sheet metal 100, glass 200, and the guide groove top strip described in any of the above embodiments. A support member 1 is fixedly mounted on the door sheet metal 100. The glass 200 can abut against the portion of the sealing buffer member 2 covering the support part 11. A decorative part 12 is located on the outer side of the glass 200. This utility model provides a vehicle door including the guide groove top strip described in any of the above embodiments. Through the integrated design of the support part 11 and the decorative part 12, the step difference between the decorative part 12 and the glass 200 is reduced, achieving a nearly flush appearance that blends with the overall vehicle design and enhances the vehicle's appearance quality.

[0037] Since the support part 11 and decorative part 12 of the guide groove top strip provided by this utility model are integrally formed of stainless steel strip, the step difference between the decorative part 12 and the glass 200 is reduced. However, a small step difference may cause the glass 200 to collide when entering the groove. In order to make the glass 200 enter the groove better, in this embodiment, the glass 200 can be pre-bent. According to the structure of the guide groove top strip and the movement trajectory of the glass 200, the glass 200 is pre-bent through a specific mold and process. During the pre-bending process, the bending angle and radius of curvature of the glass must be precisely controlled so that it can fit tightly with the sealing buffer 2 of the guide groove top strip, thereby ensuring that the glass 200 can smoothly enter the guide groove top strip during the lifting process and maintain good sealing contact with the sealing buffer 2.

[0038] In addition to pre-bending the glass 200, a better insertion effect can be achieved by adjusting the operating trajectory of the window regulator. In this embodiment, the motor control program of the window regulator is optimized to adjust its operating trajectory, causing the glass 200 to shift towards the inside of the vehicle during the lifting process. In actual adjustment, the operating parameters of the window regulator, such as the motor speed and torque, must be precisely adjusted according to the actual fit between the glass 200 and the guide rail top strip.

[0039] This embodiment also discloses a vehicle, including a vehicle door as described in any of the above embodiments.

[0040] As can be seen from the above specific embodiments, the guide groove top strip design of this utility model patent has been optimized in terms of structure, manufacturing process, installation, and coordination with other components. This design achieves a near-flush appearance, improves manufacturability and compatibility, and reduces costs. This design is feasible and effective, and has good market application prospects. In future automobile production, the guide groove top strip of this utility model patent is expected to be widely used.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
