Therefore, there are relatively high requirements for the appearance of the water cut trim strip. The characteristics of the product are: strip-shaped and bright, which can enhance the visual perception, highlight the texture, and have functions such as corrosion resistance and rust prevention. After the water cut trim strip is assembled, there are overlapping relationships with the door glass, A-pillar, front and rear door B-pillars, C-pillar, vehicle body sheet metal, etc. Therefore, relatively high requirements are imposed on the appearance structure and dimensional tolerance.

[0003] Currently in the industry, due to the different shrinkage rates of the various components of the vehicle water cut trim strip body, after long-term use in some environments such as high temperature in summer, there is stress pulling between them, resulting in shrinkage and deformation problems of the product over time. Eventually, there are gaps at the corresponding contact positions between the water cut trim strip and the A-pillar, B-pillar, and C-pillar on the vehicle after actual vehicle assembly, causing appearance defects, which are relatively prominent in the overall vehicle display and cannot meet the market appearance requirements.

[0023] 1. Exterior trim part; 2. Soft rubber; 3. Profiled lip; 4. Fiberglass strip; 5. Connection bracket; 6. End cap; 7. Flocked tape; 8. Assembly connecting member; 9. Profiled filling member. Specific Embodiments

[0024] To describe the technical content, the achieved purpose and the effects of the present utility model in detail, the following is described in conjunction with the embodiments and with reference to the drawings.

[0025] After assembly, the window trim strip of the vehicle exterior has overlapping relationships with mating parts such as the door glass, A-pillar, front and rear door B-pillars, C-pillar, and body sheet metal. Therefore, relatively high requirements are imposed on the appearance structure and dimensional tolerances. The window trim strip is generally composed of a steel strip + soft rubber + flocked material + end cap. The steel strip and the soft rubber are formed into the body through an extrusion molding process, and then assembled through bending, end cap assembly, notch punching, etc. to form a finished product. However, in a high-temperature environment in summer, due to the different shrinkage rates of the flocked tape, soft rubber, and the steel strip body, there is stress pulling between them, ultimately causing the product to shrink and deform over time. After shrinkage and deformation, gaps will be generated between the window trim strip and the mating parts, affecting the overall aesthetics.

[0026] Based on this, as Figure 1 and Figure 2 shown, the present application proposes a vehicle window trim strip, including a trim strip body and a glass fiber strip; the trim strip body is integrally injection-molded by an exterior part and soft rubber, and a profiled lip is provided on the soft rubber; the glass fiber strip is embedded in the profiled lip, and the glass fiber strip penetrates through the profiled lip along the length direction of the profiled lip.

[0027] In the above solution, the profiled lip of the soft rubber and the glass fiber strip are co-extruded and formed; due to the material characteristics of the glass fiber, it will not shrink and deform at high temperatures, and the glass fiber is embedded in the soft rubber, thus ensuring that due to the stress pulling of the glass fiber at high temperatures, the soft rubber will not shrink and deform, so that the entire window trim strip will not deform.

[0028] In some embodiments, as Figure 1 shown, the window trim strip further includes a connecting bracket, and the connecting bracket is integrally formed with the exterior part; the connecting bracket is embedded in the soft rubber; the connecting bracket serves as the attachment and support basis for the soft rubber to realize the connection between the soft rubber and the exterior part; as a preferred design, the connecting bracket can be made of stainless steel strip; the soft rubber can be selected as PVC plastic; during the production of the finished product, the rolled stainless steel strip, PVC plastic, and glass fiber are co-extruded, and then three-dimensional bending is performed by a three-dimensional bending machine, and then sawing is carried out to form.

[0029] Moreover, during actual installation, the window trim strip needs to overlap with multiple mating parts. Therefore, the profiled lip is preferably provided with at least two; the shape and size of each profiled lip are determined according to the shape of the mating part it needs to overlap and its location on the vehicle, and the glass fiber strip corresponds to the profiled lip one by one; a flocked tape is provided on the surface of the profiled lip for overlapping the mating part, and the flocked tape can be fixed by a detachable connection method such as gluing. At the same time, a profiled filling part is also provided on the exterior part, and the profiled filling part can be made of the same material as the soft rubber, and is used to fill the gap between the exterior part and other mating parts.

[0030] In some embodiments, at both ends of the trim strip body in the length direction, there is respectively provided one of the end caps 6, and the end cap is provided with an assembly connecting member; the water cut trim strip is assembled at the corresponding position on the vehicle through the assembly connecting member of the end cap. To improve the assembly convenience, the assembly connecting member is an installation buckle, and the installation position provides a mating installation opening.

[0031] Please refer to Figure 1 and Figure 2 , Embodiment 1 of the present utility model is:

[0032] A vehicle window frame water cut trim strip includes a trim strip body, a glass fiber strip, a velvet tape, and an end cap; the trim strip body is integrally injection molded by an exterior trim piece and a soft rubber, and the soft rubber is provided with a profiled lip; the glass fiber strip is embedded in the profiled lip, and the glass fiber strip penetrates through the profiled lip along the length direction of the profiled lip, and the velvet tape is arranged on the side of the profiled lip for lapping the mating part. There are at least two profiled lips, and the glass fiber strips correspond to the profiled lips one by one.

[0033] In this embodiment, a vehicle window frame water cut trim strip relies on embedding a glass fiber strip in the profiled lip of the soft rubber to increase the tensile stress of the profiled lip and prevent it from shrinking and deforming in some high-temperature environments.

[0034] In this embodiment, the exterior trim piece is integrally formed with a connecting bracket, and further includes a connecting bracket, and the connecting bracket is embedded in the soft rubber.

[0035] In some embodiments, the end caps are respectively arranged at both ends of the trim strip body in the length direction, and the end caps are provided with assembly connecting members. The assembly connecting member is preferably an installation buckle.

[0036] Moreover, profiled filling members are also provided at other positions of the exterior trim piece away from the connecting bracket. The profiled filling members can be made of PVC plastic and fill the gap between the water cut trim strip and other mating parts through profiled design.

[0037] To sum up, for a vehicle window frame water cut trim strip provided by the present utility model, the trim strip body is integrally injection molded by an exterior trim piece and a soft rubber. A glass fiber strip is arranged in the profiled lip of the soft rubber. The water cut trim strip is closely fitted with the mating part by relying on the profiled design of the profiled lip and the profiled filling member. The glass fiber strip penetrates through the profiled lip along the length direction of the profiled lip. By the glass fiber strip, the shrinkage rate of the soft rubber is reduced, so that the water cut trim strip will not shrink and deform due to the long-term influence of the external environment, eliminating the defect that the trim strip is likely to have a gap with the mating part after installation, making the water cut trim strip keep beautiful after installation and meeting the market appearance requirements.
