[0018] Preferably, the first elastic element 6 is selected to be a hinge and a retaining spring, the retaining spring is installed in the hinge to provide a certain elastic force, one end of the hinge is fixedly connected to the mirror cover 5, and the other end of the hinge is fixedly connected to one end of the reinforced sun visor 7. At the same time, the selected hinge has a certain damping, which can fix the reinforced sun visor 7 in the flipped position when flipped, thereby preventing the reinforced sun visor 7 from shaking during driving of the car, thereby affecting the driver's line of sight.

[0019] Preferably, the cross-sections of the first rotating shaft mounting hole 1b and the second rotating shaft mounting hole 1c are circular.

[0020] Specifically, when the sunlight is strong, the reinforced sun visor 7 needs to be opened. When the reinforced sun visor 7 is opened, the retaining spring provides elastic force to rotate one side of the hinge 180°, thereby making the reinforced sun visor 7 rotate 180° relative to the mirror cover 5, that is, making the reinforced sun visor 7 in a vertical state, thereby achieving the purpose of blocking strong light.

[0021] Furthermore, a second elastic element 8 is disposed in the second rotating shaft mounting hole 1 c , and the mirror cover 5 is connected to the sun visor body 1 in a resettable rotation manner via the second elastic element 8 .

[0022] Preferably, the second elastic element 8 is selected as a clip spring, and the clip spring is used to realize the 180° rotation of the mirror cover.

[0023] Specifically, the retaining spring as the second elastic element 8 has the following advantages: 1. Strong reliability: retaining springs are usually made of stainless steel or special alloys, and can maintain stable elasticity and reliability under a variety of environments; 2. Easy installation: retaining springs have a simple structure and usually do not require complicated installation procedures, and can be quickly installed in the equipment; 3. Easy maintenance: Due to the structure and material properties of retaining springs, they usually do not require special maintenance and are very easy to replace; 4.

Fatigue resistance: high-quality retaining springs can withstand millions of cyclic loads without failure, which makes them particularly useful in equipment that requires repetitive movement.

[0024] Furthermore, a first mirror cover mounting hole 5a is opened on one side of the mirror cover 5 along the axial direction of the first rotating shaft 3, and a second mirror cover mounting hole 5b is opened on the other side of the mirror cover 5 along the axial direction of the second rotating shaft 4, and the cross-sections of the first mirror cover mounting hole 5a and the second mirror cover mounting hole 5b are hexagonal.

[0025] Furthermore, the cross-sections of the first rotating shaft 3 and the second rotating shaft 4 are hexagonal, one end of the first rotating shaft 3 is inserted into the first rotating shaft mounting hole 1b and is interference fit with the sun visor body 1 to generate damping, the other end of the first rotating shaft 4 is inserted into the first mirror cover mounting hole 5a, one end of the second rotating shaft 4 is inserted into the second rotating shaft mounting hole 1c, and the other end of the second rotating shaft 4 is inserted into the second mirror cover mounting hole 5b.

[0026] Specifically, when the first rotating shaft 3 and the second rotating shaft 4 are respectively inserted into the first mirror cover mounting hole 5a and the second mirror cover mounting hole 5b, the first rotating shaft 3 and the second rotating shaft 4 are fixedly connected to the mirror cover 5, that is, the first rotating shaft 3 and the second rotating shaft 4 are always in a stationary state relative to the mirror cover 5. Further, one end of the second elastic element 8 is fixedly connected to the bottom end of the second rotating shaft mounting hole 1c, and the other end of the second elastic element 8 is fixedly connected to one end of the second rotating shaft 4, and the mirror cover 5 is flipped 10-180 degrees relative to the sun visor body by the elastic force of the second elastic element 8.

[0027] Preferably, the first rotating shaft 3 and the second rotating shaft 4 are made of XPE / IXPE / IXPP materials, and the sun visor body 1 and the reinforced sun visor 7 are made of thermal synthetic materials such as PU foam or PE foam to improve the softness and comfort of the sun visor. When the first rotating shaft 3 and the second rotating shaft 4 are made of XPE / IXPE / IXPP materials and inserted into the first rotating shaft mounting hole 1b and the second rotating shaft mounting hole 1c, a certain damping can be generated between the two, that is, when the mirror cover 5 is flipped, the damping generated by the two can achieve the positioning of the mirror cover 5 relative to the sun visor body 1 when flipping, that is, when the mirror cover 5 is flipped to 120° relative to the sun visor body 1, the damping generated makes the mirror cover 5 fixed at this position, and when the flip angle is adjusted to 180°, the mirror cover is continued to be flipped, and the differential damping between the two makes the mirror cover 5 fixed at this position.

[0028] Furthermore, a first magnetic unit 9 is provided on one side of the reinforced sun visor 1, and a second magnetic unit 10 is provided on one side of the mirror cover 5. When the reinforced sun visor 1 is in a folded state, the first magnetic unit 9 is magnetically connected to the second magnetic unit 10. When the reinforced sun visor 1 is unfolded, the reinforced sun visor 1 flips 180° relative to the mirror cover under the elastic force of the first elastic element 6.

[0029] Specifically, when the sunlight is not strong, there is no need to flip the reinforced sun visor 7. Under the suction of the first magnetic unit 9 and the second magnetic unit 10, the reinforced sun visor 7 is tightly attached to one side of the mirror cover 5, reducing the space it occupies.

[0030] Preferably, the first magnetic unit 9 and the second magnetic unit 10 are magnets. Magnets have the following advantages for adsorption and fixation: 1. Reliability: Magnets are a stable material that will not degrade over time, so they are very reliable in long-term applications; 2. No maintenance: Magnets do not require regular maintenance and once installed, they can continue to work for many years without degrading performance; 3. Capacitance and flexibility: Magnets are compatible with a variety of materials and can be made into various shapes and sizes to meet different application requirements.
