Description

Technical Field

[0001] The present invention relates to the technical field of automotive interior sun visors, and particularly to a self-powered color-changing sun visor and its usage method. Background Art

[0002] With the rapid development of the automotive industry, more and more people choose to travel by self-driving. Since drivers are affected by the strong sunlight on sunny days and the lights of oncoming vehicles' high beams at night, it is easy to cause traffic accidents. Therefore, it is necessary to equip sun visors in the car for shading. In automotive design, the interior sun visor seems ordinary, but actually undertakes multiple safety missions. This folding device hanging on the top of the cockpit is the first optical defense line for driving safety. When the sun rises or sets, the driver only needs to gently flip the sun visor to effectively block the dazzling light and avoid visual delay caused by strong light glare. The number of traffic accidents prevented by this basic function every year far exceeds people's imagination.

[0003] However, the sun visors originally installed in traditional cars are generally made of non-transparent materials. When strong light shines directly into the cab, users need to manually flip the original sun visor. This direct light-blocking method will cause the user to be unable to see the things behind the visor, thus affecting the field of vision and having low safety. Moreover, it can only be manually adjusted to unfold the sun visor after being irradiated by strong light and cannot be used continuously, which can no longer meet the needs of modern drivers.

[0004] Therefore, in view of the problems of the existing sun visors that need to be manually adjusted and have a narrow field of vision during shading, a self-powered color-changing sun visor and its usage method can be designed. Summary of the Invention

[0032] Please refer to Figures 1-6 , the present invention provides an embodiment: including a color-changing glass plate 1, a color-changing sun visor main body 3, a regulator 4, a first clamping plate 6, a second clamping plate 9 and a positioning lock 12. Reinforcing strips 2 are connected to both the left and right sides of the color-changing glass plate 1. The upper end of the color-changing glass plate 1 is fixedly connected to the color-changing sun visor main body 3. The middle of the upper end of the color-changing sun visor main body 3 is fixedly connected to the regulator 4. The upper end of the regulator 4 is rotatably connected to the first clamping plate 6. A first bending portion 7 is provided at the front end of the first clamping plate 6. An auxiliary push plate 8 is provided at the rear end of the first clamping plate 6. The front end of the first clamping plate 6 is slidably connected to the second clamping plate 9. A second bending portion 10 is fixedly connected to the end of the second clamping plate 9 away from the first bending portion 7. A rack 11 is fixedly connected to the front end of the second clamping plate 9. The front end of the rack 11 is connected to the positioning lock 12. The color-changing glass plate 1 can automatically adjust the light transmittance according to the light intensity, effectively reducing visual fatigue and accident risks caused by strong light glare (such as sunlight, snow reflection, and high beam lights). The regulator 4 can realize the angle adjustment of the color-changing glass plate 1, with simple operation. Also, the cooperation of the first clamping plate 6, the second clamping plate 9 and the positioning lock 12 facilitates the adaptation to the original sun visors of various vehicle models, and the installation is convenient.

[0033] Please refer to Figures 2-4, in this embodiment, the reinforcing strip 2 is made of stainless steel and has a J-shaped structure. The reinforcing strip 2 is adhesively connected to the color-changing glass plate 1 through an odorless high-strength adhesive. The reinforcing strip 2 is fixed to the color-changing glass plate 1 through the odorless high-strength adhesive, reducing the obstruction of the field of vision while enhancing the strength. The color-changing sun visor main body 3 is injection-molded from flame-retardant PC. The flame-retardant PC material improves the safety and durability of the color-changing sun visor main body 3, making it not easy to burn when encountering a fire source and ensuring the use safety. The regulator 4 is composed of a connecting column and a spherical ball. The connecting column is fixedly connected to the color-changing sun visor main body 3, and a spherical ball is fixedly connected to the side of the connecting column away from the color-changing sun visor main body 3. The rotation range of the color-changing sun visor main body 3 is 0-270 degrees. A connecting groove 5 is formed on the side of the first clamping plate 6 close to the color-changing sun visor main body 3. The connecting groove 5 matches the spherical part of the regulator 4. By rotating the spherical part of the regulator 4 in the connecting groove 5, the color-changing sun visor main body 3 can adjust the angle as needed. The first clamping plate 6 and the second clamping plate 9 are assembled after being injection-molded from flame-retardant PC. The first bending part 7 of the first clamping plate 6 and the second bending part 10 of the auxiliary push plate 8 are both coated with silicone, and iron parts are embedded in the silicone. The durability and convenience of use of the bending parts are improved through the design of silicone coating and embedded iron parts. The iron parts can form a fixed point with the strong magnet pre-stuck on the car roof lining to make it stable. The rack 11 is symmetrically arranged about the center of the second clamping plate 9. A jack is formed at the front end of the positioning lock 12. A tooth matching the rack 11 is arranged on the surface of the positioning lock 12 close to the auxiliary push plate 8. The rack 11 is engaged with the positioning lock 12. The positioning lock 12 is fixed by inserting a screw into the jack and then tightening it in the mounting hole on the auxiliary push plate 8, so as to accurately control the position of the second clamping plate 9. A strong-light photoelectric conversion board, a low-light photoelectric conversion board and a micro capacitor are assembled in the color-changing sun visor main body 3. The photoelectric conversion board integrates a light intensity detection module and a constant voltage power supply module. The light intensity detection module is used to monitor the light intensity inside the vehicle in real time, and the constant voltage power supply module is used to supply power to the color-changing glass plate 1. By integrating the functions of light intensity detection and constant voltage power supply on the photoelectric conversion board, self-power generation without an external power supply is realized. The strong-light photoelectric conversion board and the low-light photoelectric conversion board are connected in parallel to the color-changing glass plate 1. The color-changing glass plate 1 adopts a DC power supply mode and supports day-night mode switching. By replacing the traditional AC power supply mode with the DC power supply mode, electromagnetic interference can be eliminated and the system stability can be improved.

[0034] A usage method of a self-powered color-changing sun visor, which includes a self-powered color-changing sun visor as described above, and the steps are as follows:

[0035] First step, adjust the distance between the first bending part 7 and the second bending part 10 according to the width of the original car sun visor;

[0036] Second step, fit the adjusted first clamping plate 6 and second clamping plate 9 onto the original car sun visor;

[0037] In the third step, press the iron pieces inside the first bending part 7 and the second bending part 10 to make them strongly magnetically adsorbed and fixed to the pre-pasted roof lining.

[0038] In the fourth step, adjust the angle of the regulator 4 so that the color-changing glass plate 1 covers the driver's field of vision area.

[0039] In the fifth step, activate and run the photoelectric conversion system to complete the installation.

[0040] When working, in the daytime mode: when strongly illuminated, the strong-light photoelectric conversion plate is activated. When sunlight irradiates the surface of the photoelectric conversion plate, electric energy is generated through the photovoltaic effect. The converted electric energy is preferentially supplied to the color-changing glass plate 1 to drive the adjustment of its light transmittance, and the remaining electric energy is stored in the micro-capacitor inside the color-changing sun visor main body 3 to ensure that the photoelectric conversion system can still work briefly in low-light environments; in the night mode: switch to the low-light mode, the low-light photoelectric conversion plate is activated, and the color-changing glass plate 1 automatically fades and darkens to reduce the interference of high-beam lights and improve the clarity of the night vision.

[0041] Through the above steps, the intelligent adjustment of the light transmittance is realized by using the photoelectric conversion system inside the color-changing sun visor main body. The color-changing glass plate can be adjusted in angle according to driving needs through the regulator to adapt to different lighting conditions and usage scenarios, improving the flexibility and effect of sunshading, so as to solve the problems that the existing sun visor needs to be manually adjusted and the field of vision is narrow during sunshading.

[0042] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present invention.
