The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

A sun visor device 100 of a vehicle according to an embodiment of the present invention is described below with reference to fig. 1 to 3.

As shown in fig. 1 to 3, a sun visor device 100 of a vehicle according to an embodiment of a first aspect of the present invention includes: a mounting bracket 10, a sun visor 20 and a transmission mechanism 30.

The mounting bracket 10 is suitable for being mounted and fixed on a top plate of a vehicle body, and the sun visor 20 can be mounted and fixed on the top plate of the vehicle body through the mounting bracket 10. The sunshading board 20 includes sunshading board support 2 and locates sunshading board body 3 of sunshading board support 2, and sunshading board support 2 and installing support 10 rotatable coupling to make sunshading board 20 rotatable between sunshade position and storage position, sunshading board support 2 can drive sunshading board body 3 relative installing support 10 and rotate when relative installing support 10, realizes sunshading board 20 holistic sunshade effect through sunshading board body 3. The sun visor support 2 is rotatably connected with the mounting support 10, so that whether the sun visor 20 is used or not can be selected according to the requirements of a user, and the sun visor 20 can be conveniently opened or retracted.

The sun visor body 3 has relative first end 31 and the second end 32 that set up, when sun visor 20 is in the sunshade position, the second end 32 is located the below of first end 31, can make sun visor body 3 extend along vertical direction, and sun visor body 3 wholly is located driver's place ahead, can shelter from the highlight through sun visor body 3, realizes the sunshade effect of sun visor 20, satisfies driver's sunshade demand. When the sun visor 20 is in the storage position, the second end 32 is located behind the first end 31, so that the sun visor body 3 extends in the horizontal direction, the distance between the sun visor body 3 and the top plate of the vehicle body is relatively short, and the overall structure is relatively compact. The sun visor body 3 is movable relative to the sun visor support 2 in the arrangement direction of the first end 31 and the second end 32, and distance adjustment between the second end 32 of the sun visor body 3 and the sun visor support 2 can be achieved according to user requirements. For example, the sun visor body 3 may be moved in the direction from the first end 31 to the second end 32 with respect to the sun visor holder 2, or the sun visor body 3 may be moved in the direction from the second end 32 to the first end 31 with respect to the sun visor holder 2.

The transmission mechanism 30 is drivingly connected between the mounting bracket 10 and the sun visor body 3, and the transmission mechanism 30 is configured such that, when the sun visor bracket 2 rotates relative to the mounting bracket 10, the transmission mechanism 30 drives the sun visor body 3 to move in the arrangement direction of the first end 31 and the second end 32. Therefore, when the sun shield support 2 drives the sun shield body 3 to rotate relative to the mounting support 10, the distance between the second end 32 of the sun shield body 3 and the sun shield support 2 can be adjusted through the transmission mechanism 30, and the requirements of users on the extension length of the sun shield body 3 relative to the sun shield support under different conditions are met.

Wherein, during the rotation of the sun visor 20 from the storage position to the sun visor position, the sun visor body 3 moves in the direction from the first end 31 to the second end 32; during the rotation of the sun visor 20 from the sun visor position to the storage position, the sun visor body 3 moves in the direction from the second end 32 to the first end 31.
