Detailed Implementation

[0017] refer to Figures 1 to 4 A vehicle sun visor includes: a sunshade 100, a bracket portion 101, and a connecting portion 102, which are sequentially connected. The sunshade 100 includes a sunshade body 103 and a sunshade portion 200. The sunshade portion 200 includes multiple sunshade areas 201, which are sequentially arranged on the surface of the sunshade body 103. The multiple sunshade areas 201 are arranged to form a gradient light-transmitting structure 202. The color of 202 gradually changes from dark to light, and the light transmittance of the gradient light-transmitting structure 202 increases sequentially. Through the above structure, multiple light-blocking areas 201 are combined to form a gradient light-transmitting structure 202 with a color that gradually changes from dark to light and a light transmittance that gradually increases. This can gently weaken direct strong light, avoid sudden changes in the brightness of the field of vision from causing visual impact on the driver, and effectively reduce glare interference. The gradient light-transmitting structure 202 can match sunlight at different angles of illumination, taking into account both the need for light blocking and the transparency of the forward field of vision, thereby improving the driving and riding experience.

The light transmittance of the first light-shielding portion 203 and the second light-shielding portion 204 increases sequentially. Through the above structure, the first light-shielding portion 203 and the second light-shielding portion 204 form a two-level gradient light-shielding area 201. The side closer to the strong light incident side can achieve a stronger light-shielding effect, while the side farther away from the strong light maintains a higher light transmittance, realizing a step-by-step buffer of light intensity and avoiding sudden blocking of strong light or drastic changes in light that could irritate the driver's eyes.

[0019] refer to Figures 1 to 4 In this embodiment, a halo portion 300 is provided between two adjacent light-shielding areas 201. Through the above structure, the halo portion 300 fills the space between adjacent light-shielding areas 201, weakening the boundary contours of different light-shielding areas 201, achieving a smooth transition in color and light transmittance, avoiding visual breaks caused by obvious light-shielding zone boundaries, making the overall gradient light-shielding effect closer to the characteristics of natural light changes, effectively improving the optical appearance of the sun visor, and reducing the interference of the light-dark boundary on the driver's vision.

Through the above structure, the lifting device portion 400 can hold the light-shielding sheet body 103 and control its immersion in the dye solution in sections. By relying on the section immersion dyeing method, multiple layers of light-shielding areas 201 are formed from top to bottom, forming a gradient light-transmitting structure with gradient changes.

The shaft of the second stepper motor 601 drives the eccentric wheel 602 to rotate, so that the eccentric wheel 602 drives the suspension member 402 and the light-shielding sheet body 103 to swing. The first rack portion 406 is connected to the swing device 600. The first rack portion 406 also includes a first opening 4061. The first opening 4061 is located at one end of the first rack portion 406 near the suspension member 402.

The second stepper motor 601 is used to drive the eccentric wheel body 6021 to rotate. When the eccentric wheel body 6021 rotates, the first protrusion 6022 moves circumferentially along the edge of the eccentric wheel body 6021, causing the suspension member 402 to drive the light-shielding sheet body 103 to swing back and forth, and causing the dye liquid in the adjacent light-shielding areas 201 to permeate and merge with each other to form the hazy part 300. Through the above structure, the second stepper motor 601 drives the eccentric wheel 602 to rotate, and the first protrusion 6022 set on the edge of the eccentric wheel body 6021 drives the suspension member 402 and the light-shielding sheet body 103 to swing back and forth.

The temperature control component 502 is used to stably maintain the dyeing solution in the dyeing solution container 501 at an adjustable dyeing temperature of 60°C to 120°C. The physical penetration rate of the dyeing solution into the light-shielding sheet body 103 increases with increasing temperature. The control module 503 is electrically connected to the lifting device 400. The control module 503 can set the multi-segment travel distance of the vertical downward movement of the lifting device 400, and the downward movement speed of each segment can be set independently. When the drive assembly 401 drives the suspension component 402 to descend in segments, the light-shielding sheet body 103 is immersed in the dye solution from top to bottom. The control module 503 changes the immersion time of each light-shielding area 201 by controlling the descent speed, thereby changing the light transmittance of each light-shielding area 201. Through the above structure, the light-shielding sheet body 103 itself has high light transmittance, the dye solution has low light transmittance, the more the dye solution penetrates, the lower the light transmittance, the faster the descent speed, the shorter the immersion time in the liquid for that segment, the less the dye solution penetrates, and the higher the light transmittance of the corresponding light-shielding area 201.
