Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1-3 An embodiment of this utility model provides a car air vent dial structure, including a dial frame 1, a mounting shaft 4, and an auxiliary disc 17. A fan-shaped decorative cover 2 is fixedly connected to the outer left side of the dial frame 1. The fan-shaped decorative cover 2 is made of soft material with raised texture 3. The fan-shaped decorative cover 2 is provided with raised texture 3 on its outer side. The fan-shaped decorative cover 2 protects the outer side of the dial frame 1. The design of raised texture 3 increases the user's hand comfort when turning the dial. Retaining rings 5 ​​are fixedly connected to both the front and rear sides of the dial frame 1.

[0032] A rubber inner ring 6 is fixedly connected to the inner wall of the middle part of the retaining ring 5. A spring 7 is fixedly connected to the inner wall of the retaining ring 5 on the side closer to the gear wheel frame 1. A sealing ring 8 is fixedly connected to the inner wall of the retaining ring 5 on the side away from the gear wheel frame 1. A connecting ring 9 is fixedly connected to the inner wall of the bottom end of the retaining ring 5 away from the gear wheel frame 1. A rubber cover ring 10 is fixedly connected to the side of the connecting ring 9 away from the gear wheel frame 1. The connecting ring 9 and the rubber cover ring 10, pressed by the spring 7 against the sealing ring 8, fit tightly against the outside of the mounting shaft 4, thereby achieving a seal at the connection between the mounting shaft 4 and the gear wheel frame 1.

[0033] refer to Figure 1 , Figure 3 The outer part of the mounting shaft 4 engages with the middle part of the dial wheel frame 1. The outer part of the mounting shaft 4 is slidably connected to the middle part of the rubber inner ring 6. The outer part of the mounting shaft 4 is slidably connected to the inner wall of the middle part of the connecting ring 9. The end of the spring 7 away from the dial wheel frame 1 is fixedly connected to the side of the connecting ring 9 near the dial wheel frame 1. The outer part of the mounting shaft 4 is slidably connected to the inner wall of the middle part of the connecting ring 9. This design is to seal the outlet position where the mounting shaft 4 contacts the dial wheel frame 1, and also to increase the firmness of the connection between the dial wheel frame 1 and the mounting shaft 4. The end of the spring 7 away from the dial wheel frame 1 is fixedly connected to the side of the connecting ring 9 near the dial wheel frame 1. The spring 7 is supported by the retaining ring 5 near the dial wheel frame 1 and abuts against the outer part of the connecting ring 9 connected to the mounting shaft 4.

[0034] refer to Figure 2 and Figure 4 A limiting component is provided on the outside of the mounting shaft 4. The limiting component is used to limit the rotation angle of the mounting shaft 4. The limiting component includes two collars 11, two connecting rollers 12, a support rod 13, a support block 14, a limiting plate 15, and a groove 16. The front and rear sides of the mounting shaft 4 are rotatably connected to the collars 11. The middle of the mounting shaft 4 is a complete circle, which will not affect the rotation of the fixed dial wheel driven by the mounting shaft 4. The connecting roller 12 is fixedly connected to the right side of the collar 11. The support rod 13 is fixedly connected to the rear side of the connecting roller 12. The support block 14 is rotatably connected to the outside of the support rod 13. The support rod 13 connects and supports the connecting roller 12 and the collar 11.

[0035] The external rotatable connection of the support block 14 is to the limiting plate 15. The left rear end of the limiting plate 15 has a groove 16. The front side of the limiting plate 15 is slidably connected to the rear side of the rear connecting roller 12. The support rod 13 supports the limiting plate 15 to rotate stably through the support block 14. The front side of the limiting plate 15 is slidably connected to the rear end of the support rod 13 to keep the limiting plate 15 rotating horizontally and linearly. The groove 16 is a long groove with a length not exceeding the outer edge of the limiting plate 15.

[0036] A bayonet 18 is provided in the middle of the auxiliary disk 17, and a sliding column 19 is fixedly connected to the rear side of the auxiliary disk 17. The outer side of the mounting shaft 4 is engaged with the inner wall of the bayonet 18, and the outer side of the sliding column 19 is slidably connected to the inner wall of the groove 16. Because the limiting plate 15 will slide in the groove 16 of the limiting plate 15, it will push the limiting plate 15 to rotate synchronously. Because the groove 16 is a closed long groove, when the auxiliary disk 17 rotates to a certain angle, it will be restricted and pulled by the limiting plate 15 to prevent it from rotating again. This can limit the maximum rotation angle of the dial and prevent damage to key components due to misoperation or excessive force.

[0037] Working principle: The retaining ring 5 connects to the rubber inner ring 6, which fits tightly against the outside of the mounting shaft 4. In addition, the spring 7 presses against the sealing ring 8, and the connecting ring 9 and rubber cover ring 10 fit tightly against the outside of the mounting shaft 4, thereby achieving a seal at the connection between the mounting shaft 4 and the dial wheel frame 1. This effectively prevents dust, bacteria, dirt and other impurities inside the air outlet from entering the dial wheel and damaging the internal components.

[0038] Furthermore, in this structure, the mounting shaft 4 is engaged and fixed with the auxiliary disk 17. Therefore, when the mounting shaft 4 rotates, it will drive the sliding column 19 fixed to the auxiliary disk 17 to slide on the inner wall of the groove 16 of the limiting plate 15. Because the limiting plate 15 will slide in the groove 16 of the limiting plate 15, it will push the limiting plate 15 to rotate synchronously. Since the groove 16 is a completely closed long groove, when the auxiliary disk 17 rotates to a certain angle, it will be restricted and pulled by the limiting plate 15 to prevent it from rotating again. This can limit the maximum rotation angle of the dial and prevent damage to key components due to misoperation or excessive force.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
