[0003] Traditional automotive sun visors usually include a mounting base and a sun visor body. When in use, the mounting base is directly mounted on the automotive lining, and the sun visor body can rotate relative to the mounting base through a rotating structure to adjust the sunshade angle. There is a frictional damping force between the rotating structure of the sun visor body and the mounting base. When rotating the sun visor body, the frictional damping force is used to consume the rotational kinetic energy of the sun visor. At the same time, the frictional damping force can ensure the static balance of the sun visor body after the sun visor body adjusts the angle, thereby reducing the shaking of the sun visor caused by vibrations and other situations. However, the frictional damping force is determined by the mounting dimensions during the design and installation of the sun visor and cannot be adjusted according to the usage habits of the driver.

[0006] As an improvement, the sliding structure includes a sliding plate and a connecting column; the sliding plate is slidably arranged in the groove, the connecting column is fixedly connected to the sliding plate, and the connecting column is connected to the friction plate through a friction adjusting component.

[0020] By adding a sliding structure and a friction adjustment assembly in the sun visor 3, the driver can conveniently adjust the frictional damping force when the sun visor 3 rotates, so as to adapt to the habits of different drivers, and can also readjust the frictional damping force under long-term wear, thereby prolonging the service life of the sun visor 3.

[0021] As Figure 3 shown, the sliding structure includes a sliding plate 11 and a connecting column 12; The sliding plate 11 is slidably arranged in the groove 10, the connecting column 12 is fixedly connected to the sliding plate 11, and the connecting column 12 is connected to the friction plate 13 through a friction adjustment assembly.

[0022] A screw 9 is rotatably arranged in the groove 10, and the sliding plate 11 is threadedly connected to the screw 9; The sliding plate 11 and the groove 10 are mutually corresponding cuboid structures, and the sliding plate 11 is mutually attached to the inner wall of the groove 10, which can limit the rotation of the sliding plate 11, thereby converting the rotation of the screw 9 into the sliding of the sliding plate 11 and driving the friction plate 13 to slide, so as to change the mutual pressure between the friction plate 13 and the fixed shaft 2.

[0023] A countersunk hole 8 is provided at the bottom of the sun visor 3, and the operating end of the screw 9 is located within the countersunk hole 8; this prevents the operating end of the screw 9 from protruding from the sun visor 3 and scratching the driver or passengers.

[0026] Principle of the present utility model

[0027] As Figures 1-2 As shown, the sun visor 3 is connected to the mounting seat 1 through two rotating assemblies. One is the rotation between the rotating hole 4 of the sun visor 3 and the fixed shaft 2, and the other is the rotation between the rotating shaft 6 on the sun visor 3 and the card slot 7 within the elastic fixing block 5; and the connections of both rotating assemblies can provide a fixed frictional damping force for the normal rotation of the sun visor 3, and this frictional damping force should be designed to be relatively small during design.

[0028] As Figure 3 As shown, that is, the mating structure of the friction plate 13 with adjustable frictional damping force and the fixed shaft 2 provided in this application. When it is necessary to increase the frictional damping force, simply turn the screw 9 from the position of the countersunk hole 8, driving the sliding plate 11 to slide within the groove 10. As Figure 4 As shown, the upper support plate 16 remains stationary, while the lower support plate 15 and the sliding column 20 slide upward relative to the upper support plate 16, compressing the spring 19, thereby increasing the pressure of the friction plate 13 on the fixed shaft 2. And the greater the mutual pressure between two objects, the greater the frictional force between them. Therefore, the frictional damping force during the rotation of the sun visor 3 can be increased; similarly, if it is necessary to reduce the frictional damping force, simply reverse the screw 9 to reduce the compression amount of the spring 19, thereby reducing the pressure of the friction plate 13 on the fixed shaft 2.

[0029] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
