[0023] 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.

[0024] To address the issue that installing a filter sunshade can easily cause structural damage to the original sunshade in existing technologies, the following technical solution is provided. Please refer to [link / reference needed]. Figure 1-4 ;

[0025] A lightweight car sun visor mounting bracket includes a snap-fit ​​base 1, which includes an upper snap-fit ​​plate 7 and a lower snap-fit ​​plate 8. The upper snap-fit ​​plate 7 and the lower snap-fit ​​plate 8 are connected on one side, so that the snap-fit ​​base 1 forms a U-shaped opening structure. The cavity between the upper snap-fit ​​plate 7 and the lower snap-fit ​​plate 8 forms a snap-fit ​​groove 2, which is used to insert the original car sun visor 9.

[0026] The buckle base 1 is made of PA66-GF30 nylon material with a glass fiber content of 30% and a density of ≤1.45g / cm3; the upper buckle plate 7 and the lower buckle plate 8 are integrally injection molded, with a wall thickness of 2.5mm at the connection; the formed snap groove 2 has a height of 15±0.2mm and an adjustable groove width of 8-12mm.

[0027] The inner walls of the upper buckle plate 7 and the lower buckle plate 8 are respectively provided with a row of V-shaped auxiliary strips 3. The V-shaped auxiliary strips 3 are evenly distributed. The opening direction of the V-shaped auxiliary strips 3 faces the buckle interface 5 of the buckle groove 2. The V-shaped auxiliary strips 3 are composed of two symmetrical flexible fins 4. The flexible fins 4 are inclined relative to the inner wall of the buckle groove 2. The angle between the flexible fins 4 and the inner wall of the buckle groove 2 is 40°-50°. The inclination direction is consistent and faces the bottom 6 of the buckle groove 2. The surface of the flexible fins 4 has friction texture.

[0028] The number of single-row V-shaped auxiliary strips 3 is 6-10 sets, with a set spacing of 4mm. The thickness of the flexible fin 4 is 0.8mm, and the Shore hardness is 85A. When the original sunshade 9 is inserted, the flexible fin 4 produces an elastic deformation of 0.5-1.2mm, providing a continuous clamping force of 50-80N. Vibration tests at frequencies of 5-500Hz show that the displacement of this structure is <0.05mm.

[0029] When installing the snap-on base 1, the original sun visor 9 is in a closed state, with the snap-on interface 5 facing the side edge of the original sun visor 9, so that the original sun visor 9 is inserted into the snap-on groove 2. During this process, the flexible fin 4 adapts to the original sun visor 9 of different thicknesses through deformation, and achieves non-damaging clamping by relying on the elasticity and friction coefficient of the material, without the need for adjusting screws or other fixing components. The tilt and angle settings of the flexible fin 4 ensure that the snap-on base 1 will not shift during vehicle vibration after installation.

[0030] A hinge seat 10 is symmetrically arranged on the side of the bottom surface of the lower buckle plate 8 facing the card interface 5. The pivot diameter of the hinge seat 10 is 3-6mm, made of POM material. The pivot diameter is 3-6mm and the pivot is interference-fitted with the hinge seat 10. The pivot can only be rotated by manually pushing the light filter sunshade 13 to apply force. The pivot remains in a fixed position when stationary. The hinge seat 10 is rotatably connected to both ends of the U-shaped locking rod 11. The U-shaped locking rod 11 has a slot 12. The depth direction of the slot 12 is perpendicular to the length direction of the U-shaped locking rod 11. The width of the slot 12 is 4.0±0.1mm. The thickness of the slot 12 is less than the thickness of the light filter sunshade 13. The slot 12 is interference-fitted with the light filter sunshade 13. The light filter sunshade 13 is made of 4.5mm thick PC material with an interference of 0.5mm. The inner edge of the slot 12 has rounded corners to facilitate the insertion of the light filter sunshade 13.

[0031] The entire process requires no auxiliary tools. The two-stage sunshade is installed synchronously and stably through structural deformation, and all components are made of lightweight materials to reduce the overall weight.

[0032] Working Principle: The mounting bracket works by utilizing the synergistic effect of the snap-fit ​​base 1 and the hinge mechanism to secure the double sun visors. When installing the bracket, first keep the original sun visor 9 closed, and align the snap-fit ​​interface 5 of the snap-fit ​​base 1 with the side edge of the original sun visor 9. Apply vertical force to insert the original sun visor 9 into the snap-fit ​​groove 2 along the snap-fit ​​interface 5. During this process, the upper and lower surfaces of the original sun visor 9 contact the V-shaped support strips 3 on the inner walls of the upper snap-fit ​​plate 7 and the lower snap-fit ​​plate 8, forcing the flexible fins 4 of the V-shaped support strips 3 to undergo elastic deformation. The 40°-50° tilt design of the flexible fins 4 causes them to bend towards the bottom 6 of the groove, adapting to the different thicknesses of the original sun visor 9 through material elasticity. Simultaneously, the surface friction texture generates static friction, achieving damage-free clamping.

[0033] When the original sun visor 9 is fully inserted into the bottom 6 of the contact groove, the continuous rebound force of the flexible fins 4 forms a clamping force of 50-80N, ensuring that the displacement of the bracket is less than 0.05mm under vehicle vibration. At this time, the snap-fit ​​base 1 has completed the fixation of the original sun visor 9.

[0034] For the installation of the additional light-filtering sunshade 13, the U-shaped locking rod 11 connected to the bottom surface of the lower latching plate 8 needs to be rotated. This U-shaped locking rod 11 rotates 180° via the pivot of the hinge seat 10. Align the edge of the light-filtering sunshade 13 with the slot 12 on the U-shaped locking rod 11. Since the width of the slot 12 is smaller than the thickness of the light-filtering sunshade 13, a 0.5mm interference fit occurs during insertion. The PC material light-filtering sunshade 13 undergoes slight deformation within the slot 12, forming a mechanical locking structure, and is finally fixed by the repositioning of the U-shaped locking rod 11.
