[0002] Modern car sun visors commonly integrate vanity mirrors, and to enhance the user experience, especially in low-light conditions, most vanity mirrors are also equipped with supplemental lighting. Existing illuminated vanity mirror structures typically include a frame, mirror, cover, and lighting components. These components are usually secured by individual installations of multiple parts or by complex clips and screws, which presents the following problems: First, the assembly process is cumbersome, resulting in low production efficiency and difficulty in automating production; second, when a component (such as the mirror or bulb) fails, repair and replacement are very inconvenient, often requiring the replacement of the entire assembly, leading to high costs.

[0003] Therefore, a sun visor frame structure that is simplified, easy to assemble, accurately positioned, and easy to maintain is needed. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the assembly process of the mirror frame structure on the existing sun visor is cumbersome, the production efficiency is low, and it is difficult to achieve automated production; moreover, when the lens or bulb is damaged, repair and replacement are very inconvenient, often requiring the replacement of the entire assembly, which is costly.

[0005] To solve the above problems, the technical solution of this utility model is: a mirror frame structure for a car sun visor, including a mirror frame, a lens installed inside the mirror frame, and a cover plate rotatably installed on the mirror frame;

[0006] The top surface of the eyeglass frame has a groove, and the bottom surface has a mounting groove. The groove contains an upwardly protruding positioning frame. The top surface of the positioning frame has a through groove 1 that fits the lens. Through groove 2 is symmetrically provided on both sides of through groove 1. A fill light is installed inside through groove 2 in the mounting groove. A positioning post is fixedly connected between through groove 1 and through groove 2 inside the mounting groove. Positioning plate 1 and positioning plate 2, which are used to fix the lens and the fill light respectively, are detachably installed on the positioning post. Limiting strips are fixed around the eyeglass frame to fix the eyeglass frame in the reserved opening of the sun visor.

[0007] Furthermore, the cover plate is rotatably mounted in the groove via a damping hinge, and an annular groove is formed between the outer side wall of the positioning frame and the inner side wall of the groove. A fixing ring that engages with the outer side of the positioning frame is fixed to the bottom surface of the cover plate.

[0008] Furthermore, a micro switch for controlling the fill light is embedded and installed in the lower part of the positioning frame below the through groove 2, and a protrusion corresponding to the position of the micro switch is provided on the inner side of the cover plate.

[0009] Furthermore, a light guide plate is embedded in the second through slot.

[0010] Furthermore, L-shaped positioning strips are fixedly connected to the four corners of the through groove inside the mounting groove, and the lens is snapped and fixed to the inside of the four positioning strips.

[0011] Furthermore, the second positioning plate has a positioning groove adapted to the fill light by bending, and the fill light is fixed to the second positioning plate by adhesive.

[0012] The advantages of this utility model compared with the existing technology are as follows: the overall layout is achieved through the positioning frame, and the lens and the supplementary light are fixed by positioning plate one and positioning plate two respectively. The structure is clear, the assembly logic is simple, which can greatly improve the assembly efficiency of the production line and is easy to automate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 3As shown, a mirror frame structure for a car sun visor includes a mirror frame 1, a lens 2 installed inside the mirror frame 1, and a cover plate 3 rotatably installed on the mirror frame 1. The mirror frame 1 serves as the basic carrier of the entire structure and is preferably integrally molded from PC / ABS alloy material through injection molding. This material has high strength, high toughness, and good dimensional stability, which can meet the requirements of automotive interior parts for mechanical properties and environmental resistance.

[0019] The front of the frame 1 (the side facing the user when in use) is designed with a recessed groove, within which is a raised positioning frame 4. The positioning frame 4 and the outer wall of the groove form a continuous annular groove.

[0020] The top surface of the positioning frame 4 serves as the main functional interface. A rectangular through slot 1 is provided in the middle to display the lens 2. On the left and right sides of the through slot 1, two long strip through slots 2 are symmetrically provided to serve as the light outlets of the supplementary light 5.

[0021] On the back of the frame 1, there is a mounting groove corresponding to the groove on the front. All functional components are installed and fixed in this groove. To enable quick installation of the frame 1 assembly and the sun visor body, an outwardly extending limiting strip 9 is integrally formed around the frame 1 body. The size of the limiting strip 9 is slightly larger than the reserved opening on the sun visor. During installation, the entire frame structure can be firmly and aesthetically fixed to the sun visor through an interference fit.

[0022] The lens 2 is a conventional glass lens, and its positioning mechanism consists of two steps: First, at each of the four inner corners of the through groove 1, a positioning strip 13 of L-shaped cross-section made of a breaking material is fixed. The four positioning strips 13 together form a precise rectangular frame. After the lens 2 is inserted, its four corners are respectively limited from both sides by the L-shaped positioning strips 13, achieving precise positioning in the horizontal plane. From the back of the frame 1, multiple positioning plates 7 are used to cover the back of the lens 2. The positioning plates 7 have mounting holes corresponding to the positioning posts 6 in the mounting groove. The positioning plates 7 are locked to the positioning posts 6 by screws, thereby firmly pressing the lens 2 into the inside of the positioning strips 13.

[0023] An LED supplementary light 5 is installed inside the mounting slot at the second through slot. To achieve efficient and uniform lighting, a light guide plate 12 is first embedded in each second through slot. The light guide plate 12 can convert the point light source of the LED into a uniform surface light source. The fixing of the supplementary light 5 also adopts a modular approach: it is first fixed to a dedicated positioning plate 8 with thermally conductive adhesive. The positioning plate 8 is made of metal sheet by stamping and bending, and has a positioning groove that matches the shape of the supplementary light 5 to ensure installation accuracy. Then, this "light module" (positioning plate 8 + supplementary light 5) is installed on the positioning post 6 through the mounting holes on the positioning plate 8 and fixed. This design allows the lighting components to be pre-assembled and tested as an independent unit, greatly simplifying the overall assembly process and facilitating later individual maintenance and replacement.

[0024] The cover plate 3 is rotatably connected to one edge of the groove on the top surface of the mirror frame 1 via a damping hinge (not shown in detail in the figure, but a conventional component in the art). The damping hinge ensures that the cover plate 3 can stably remain at any opening angle, improving the user experience. A retaining ring 10 is fixedly bonded to the inner side of the cover plate 3 (the side closest to the mirror frame). When the cover plate 3 is closed, the retaining ring 10 fits precisely into the annular groove on the front of the mirror frame 1, tightly fitting around the periphery of the positioning frame 4. This design achieves three optimizations: first, it improves the sealing performance when closed, effectively preventing dust; second, it enhances the structural stability of the cover plate after it is closed, avoiding abnormal noises caused by vibration during vehicle operation; and third, it serves as a guide and positioning mechanism, ensuring accurate positioning each time the cover plate is closed.

[0025] To achieve the intelligent function of "lights up when the cover is opened and turns off when the cover is closed", a micro switch 11 is embedded in the positioning frame 4 below the through slot 2. When the cover 3 is closed, the protrusion on its inner side will press down on the contact of the micro switch 11, putting it in the "disconnected" state, and the fill light 5 will turn off. When the cover 3 is opened, the pressure is released, the contact of the micro switch 11 is reset by its own elasticity, the circuit is "connected", and the fill light 5 will automatically light up. This control logic is simple and reliable, greatly improving the user experience.

[0026] In practical use, the light guide plate 12 is embedded into the through groove 2, the back of the frame 1 is placed facing up, the lens 2 is placed in the space surrounded by four L-shaped positioning strips 13, the positioning plate 1 7 is covered on the back of the lens 2 and fixed on the positioning post 6, the fill light 5 is glued and fixed in the positioning groove of the positioning plate 2 8, the "lamp assembly sub-module" (positioning plate 2 8 and fill light 5) is fixed on the positioning post 6, the cover plate 3 is installed on the frame 1 through the damping hinge, the wiring harness of the fill light 5 and the micro switch 11 is connected to the external connector, the assembled frame assembly is pushed from the back of the sun visor to its reserved opening, appropriate pressure is applied, so that the limiting strips 9 around the frame 1 are tightly engaged with the edge of the sun visor opening, and the final installation is completed.

[0027] The positioning frame 4 serves as an integrated reference, working in conjunction with modular positioning plates 7 and 8 to make the assembly process clear, quick, and suitable for automated production. If the lens 2 or the supplementary light 5 is damaged, it can be replaced simply by removing the corresponding positioning plate, without having to replace the entire assembly, resulting in extremely low maintenance costs.
