car sun visor

Abstract

The invention discloses an automotive sun shield, relates to the technical field of automotive interior trimming and aims to solve the problem that the automotive sun shield is short in service life. The automotive sun shield comprises a base, a rotating shaft, a U-shaped snap spring, and a sun shield body; the rotating shaft is fixed on the base; the U-shaped snap spring is clamped onto the rotating shaft; the sun shield body is fixedly connected with the U-shaped snap spring. An area, in contact with the U-shaped snap spring, of the rotating shaft includes a first shaft segment and second shaft segments at two ends of the first shaft segment; the first shaft segment is provided with an axial plane; the width of the axial plane is smaller than the diameter of the first shaft segment; the diameter of the first shaft segment is smaller than that of the second shaft segments. After the sun shield body is attached to the top of an automobile, a fastening portion on one side, corresponding to the axial plane, of the U-shaped snap spring and the areas, corresponding to the two second shaft segments, of the U-shaped snap spring are provided with notches respectively, and the width, in a direction perpendicular to the rotating shaft, of each notch is larger than the diameter of the second shaft segments. The automotive sun shield is used for shielding sunlight to improve driving safety.

Description

Technical field [0001] The present invention relates to the technical field of automobile interior decoration, in particular to an automobile sun visor. Background technique [0002] The car sun visor is a suspension installed above the front windshield of the car, which is used to block the sun when the car is driving towards the sun and improve driving safety. The traditional car sun visor includes: a base fixedly connected with the car roof, a rotating shaft fixed on the base, and a sun visor body sleeved on the rotating shaft; wherein a U is provided in the shaft hole of the sun visor body and the rotating shaft. The shape of the circlip is provided with an axial plane on the shaft section where the rotating shaft contacts the U-shaped circlip. When in use, the torque generated by the friction between the U-shaped circlip and the rotating shaft enables the sun visor body to stay at any position and automatically attach to the top. [0003] However, the inventor of the present...

Problems solved by technology

[0003] However, the inventors of the present application have found that in the above-mentioned car sun visor structure, the shaft sections where the rotating shaft contacts the U-shaped retaining spring are all equal in diameter, and in order to ensure that the sun visor body can stay at any position and automatically attach to the top, the U-shaped clamp The friction between the spring and the rotating shaft is relatively large, causing the rotating shaft and the U-shaped retaining spring to wear too quickly, which seriously affects the service life of the car sun visor
