TECHNICAL FIELD

[0001] The present application relates to the technical field of sun visors, and particularly to a multi-directional rotating support assembly of a sun visor for an automobile. BACKGROUND

[0002] A sun visor is an important part in the interior of a vehicle for blocking sunlight and ensuring driving safety. At present, most sun visors are equipped with a single-axis rotating structure. The typical working mode is that the sun visor body is connected to the front part of the roof through a rotating shaft and can be flipped downward to block sunlight from the front windshield. When it is necessary to block sunlight from the side window, the fixed point on the inner side is disengaged, and the entire sun visor is rotated to the side window position with the single axis as the center.

[0003] However, due to the design of the automobile body shape, there is a significant height difference between the front windshield and the side window in the front pillar area of some vehicles. The top edge line of the side window glass is usually much lower than the top edge line of the front windshield. When the traditional sun visor is rotated to the side window with its fixed axis as the center, the traditional sun visor has a fixed and non-adjustable circular arc trajectory. This results in the final position of the sun visor being unable to match the lower side window area in the vertical direction, thereby leaving a light transmission gap between the top of the sun visor and the roof, or between the edge of the sun visor and the front pillar. The light transmission gap makes the sun visor unable to effectively block low-angle sunlight from the side front in actual use, seriously affecting the shading effect and the visual comfort of the driver, and even possibly causing safety hazards due to glare. SUMMARY

[0004] In order to solve the technical problem that the traditional single-axis sun visor cannot effectively cover the side window area after rotation due to the height difference between the front windshield and the side window of the automobile, the present application provides a multi-directional rotating support assembly of a sun visor for an automobile.

[0038] When the sun visor is in a state of being close to the side window of the vehicle body, the special-shaped gasket 4 is located above the guide protrusion 41 at this time; when the sun visor is removed from the fixing, it will start to naturally sag due to its own weight, at this time, the first guide inclined surface and the second guide inclined surface will be in contact during the free sagging process of the sun visor, and will slide downward according to the inclination angle of the second guide inclined surface until the sun visor is in a naturally sagging state, and then the sun visor can be rotated to be close to the front windshield or be returned to the original position.

[0039] The implementation principle of the multi-direction rotating support assembly of the automobile sun visor is as follows: when it is needed to shield sunlight of the side window, the user first rotates the sun visor horizontally to the side of the door, at this time, the sun visor rotates in the first mounting joint 11 through the support shaft 5; then the sun visor is turned up, at this time, the whole rotating joint 1 drives the support shaft sleeve 2 to rotate on the support shaft 35 until the sun visor is fixed to the side of the vehicle body, and full coverage shielding of the side window is completed.

[0040] When the sun visor is folded, after the side fixing is released, the sun visor is lowered under the action of gravity. In this process, the guide protrusion 41 on the special-shaped gasket 4 slides along the inclined surface of the guide boss 34 on the support 3, forcing the sun visor to accurately reset to the initial position along the predetermined path.
