Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a rotatable dual-zone sun visor and its side window roller blind extension device. Background Technology

[0002] Car sun visors are an indispensable part of automobiles. Currently, car sun visors on the market have a rotating shaft at one end, with the end of the shaft away from the sun visor rotatingly connected to the inner top of the car frame. The other end of the sun visor is fixed with a clamping shaft, which engages with a sun visor hook installed on the inner top of the car frame and rotates. When the sun visor needs to block sunlight from the front, it can be rotated downwards. When the sun visor needs to block sunlight from the side of the car, the clamping shaft can be disengaged from the sun visor hook, and the sun visor can be rotated horizontally to block sunlight from the side of the car.

[0003] For example, a car sun visor with application number CN202321250258.8 and authorization announcement date of 20231020 includes a pivot and a housing. One end of the pivot is rotatably connected to one side of the housing, and the other end of the pivot is used to fix it to the inner top of the car frame. The car sun visor also includes a light-transmitting sun visor made of plastic material, which is disposed below the housing. The housing includes a front housing assembly and a rear housing assembly distributed in a front-rear direction. The front housing assembly and the rear housing assembly are fixed together, and the upper end of the light-transmitting sun visor is fixed between the front housing assembly and the rear housing assembly. This utility model can not only block sunlight, but also avoid obstructing the driver's vision when the car sun visor is in use.

[0004] Traditional car sun visors can only block the windshield or part of the side window area and cannot be adjusted in multiple dimensions, resulting in an inability to flexibly cover sunlight from different angles. Therefore, there is an urgent need to design a rotatable dual-zone sun visor and its side window roller blind extension device to solve the above problems. Utility Model Content
