[0002] As an important decorative component of the vehicle body, automotive door and window bright trim strips not only need to be aesthetically pleasing but also require convenient installation and structural stability. Traditional bright trim strip structures typically use bolt fixing or clip-on connections, but in practical applications, these structures often suffer from low assembly efficiency and insufficient stability. Therefore, developing a new automotive door and window bright trim strip structure that achieves rapid installation and reliable fixation has become a technical problem urgently needing to be solved by those skilled in the art.

[0003] Currently, the common methods for fixing automotive door and window trim strips in existing technologies mainly include bolt fastening and clip-on connections. Bolt fixing connects the trim strip to the car body through threaded engagement. Although the structure is stable, the installation process is cumbersome, requires specialized tools, and is time-consuming. Clip-on connections use elastic clips to engage with the car body sheet metal for fixation. While installation is more convenient, over long-term use, vibration or external forces can cause loosening or even detachment, affecting the stability and aesthetics of the trim strip.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 The present invention provides an embodiment of a car door and window bright trim strip structure, including a bright trim strip body 1, which serves as the main decorative component and provides overall structural support and installation reference. The outer wall of the bright trim strip body 1 is fixedly connected to a mounting post 1 2, which cooperates with a mounting post 2 3 to achieve the initial positioning and guiding function of the bright trim strip. The outer wall of the mounting post 1 2 is slidably connected to the mounting post 2 3, which has a built-in disassembly and assembly component to provide sliding space and installation reference for the locking block 1 7. The inner wall of the mounting post 2 3 is provided with a disassembly and assembly component.

[0027] The assembly includes a locking block 7, which, after being pressed by the mounting post 2, resets and snaps into the groove to achieve initial locking. The outer wall of the locking block 7 is slidably connected to the inner wall of the mounting post 3. One end of the locking block 7 is fixedly connected to a spring 10, which provides a reset elastic force to ensure locking stability. One end of the spring 10 is fixedly connected to a locking block 9, which is linked with the locking block 7 to enhance locking reliability. The outer wall of the locking block 9 is slidably connected to a sliding post 6. The outer wall of the sliding post 6 is fixedly connected to a spring 8, which provides a reset elastic force to maintain the working position of the locking block 9. The outer wall of the sliding post 6 is fixedly connected to a sliding disc 5, which connects the sliding post 6 and the sliding rod 4 to realize force conversion and transmission. The outer wall of the sliding disc 5 is fixedly connected to a sliding rod 4. The outer wall of the sliding rod 4 is fixedly connected to a sliding rod 11, which drives the sliding rod 13 to move, realizing the secondary locking function.

[0028] Specifically, the operator first aligns the mounting post 2 of the bright trim strip body 1 with the slot of the mounting post 3 and inserts it. During the insertion process, the locking block 7 inside the mounting post 3 is squeezed by the inclined surface of the mounting post 2, forcing the locking block 7 to move inward. The movement of the locking block 7 is transmitted to the locking block 9 through the spring 10, causing the locking block 9 to compress the spring 10 and produce elastic deformation. At the same time, the sliding post 6 drives the sliding disk 5 to move axially under the pre-tightening force of the spring 8, thereby driving the sliding rod 4 and the sliding rod 11 to slide smoothly in the guide groove of the bright trim strip body 1. When the mounting post 2 is fully inserted, the locking block 7 is accurately reset under the restoring force of the spring 10, and its protruding part is reliably locked into the corresponding groove of the mounting post 2, completing the initial positioning and fixing of the bright trim strip body 1.

[0029] Reference Figures 1-3A fixing plate 12 is fixedly connected to the outer wall of the bright trim strip body 1, providing a guide for the slide rod 13 and serving as a fixing reference surface. A connecting plate 14 is fixedly connected to the outer wall of the fixing plate 12, connecting to the vehicle body structure and providing the final installation fixing point. A fixing component is provided inside the slide rod 11, including the slide rod 13, which slides within the fixing sleeve 15, driving the fixing plate 17 to achieve clamping. The outer wall of the slide rod 13 is slidably connected to the inner wall of the slide rod 11, and the fixing plate 17 is fixedly connected to the outer wall of the slide rod 13. Under the action of the spring 16, the fixing plate 12 is clamped, achieving final locking. The spring 16 is sleeved on the outer wall of the slide rod 13, providing continuous clamping force to the fixing plate 17 to prevent loosening. The outer wall of the slide rod 13 is slidably connected to the fixing sleeve. 15. Limit the stroke of slide bar 13 to ensure moderate clamping force. The outer wall of the fixed sleeve 15 is fixedly connected to the outer wall of the connecting plate 14. One end of spring 16 is fixedly connected to the outer wall of the fixed plate 17, and the other end of spring 16 is fixedly connected to the outer wall of the fixed sleeve 15. The outer wall of slide bar 13 is slidably connected to the inner wall of the fixed plate 12. The fixed plate 17 is attached to the outer wall of the fixed plate 12. One end of spring 8 is fixedly connected to the inner wall of the mounting post 2 3. The outer wall of the locking block 7 is slidably connected to the inner wall of the mounting post 2. The outer wall of slide bar 4 is slidably connected to the inner wall of the bright trim strip body 1. The outer wall of slide bar 2 11 is slidably connected to the inner wall of the bright trim strip body 1. The mounting post 2 3 is set on one side of the outer wall of the bright trim strip body 1. The outer wall of the sliding plate 5 is slidably connected to the inner wall of the mounting post 2.

[0030] Specifically, the continued movement of slide rod 11 drives slide rod 13 to slide precisely within the guide hole of the fixing plate 12. Under the continuous elastic force of spring 16, the fixing plate 17 is tightly attached to the working surface of the fixing plate 12, forming a stable axial clamping force. At the same time, the fixing sleeve 15 effectively limits the displacement of slide rod 13, ensuring the connection rigidity between the bright trim body 1 and the connecting plate 14. During this process, the elastic force provided by spring 8 and spring 10 keeps the locking block 7 and locking block 9 in a good locking state, effectively preventing the loosening of the mounting post 2 under vibration conditions, thereby achieving reliable fixing and long-term stable connection of the bright trim body 1.

[0031] Working principle: When the bright trim structure of the car door window is needed, during the installation of the bright trim, the mounting post 1 2 of the bright trim body 1 is aligned with the mounting post 2 3 and inserted. The locking block 7 inside the mounting post 2 3 is squeezed by the mounting post 1 2, pushing the locking block 2 9 to compress the spring 2 10. At the same time, the sliding post 6 drives the sliding plate 5 to move under the action of the spring 1 8, so that the sliding rod 1 4 and the sliding rod 2 11 slide along the bright trim body 1. When the mounting post 1 2 is fully inserted into the mounting post 2 3, the locking block 1 7 is reset under the elastic force of the spring 2 10 and is locked into the corresponding groove of the mounting post 1 2, thus achieving initial fixation.

[0032] In addition, when locking the bright trim strip, slide bar 2 11 drives slide bar 3 13 to slide within the fixed plate 12. The fixed plate 17 is pressed tightly against the fixed plate 12 under the elastic force of spring 3 16. At the same time, the fixed sleeve 15 restricts the displacement of slide bar 3 13, so that the bright trim strip body 1 is firmly connected to the connecting plate 14. At this time, spring 1 8 and spring 2 10 work together to ensure that the locking block 1 7 and locking block 2 9 remain locked, preventing the mounting post 1 2 from loosening, thereby completing the firm installation of the bright trim strip body 1.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
