Light-proof device basically not blocking sight, preventing high beam of vehicle and strong light on road and protecting eyes

Abstract

The invention provides a light-proof device which basically does not shield the sight line, can prevent high beam of a vehicle and strong light on a road and can protect eyes. The light-proof device comprises a light-proof device plastic sheet main body, a rope penetrating hole, a thickened plastic sheet, a square magnet or an iron sheet adhered to the back of the light-proof device plastic sheet main body, a magnet adhered to a driving front window glass, a suction cup adsorbed to the glass and the like. The light blocking principle is similar to that hands and arms block distance light and strong light on the road, but the defects are overcome as far as possible, and different areas have different degrees of light transmittance. The upper portion of the light-proof device plastic sheet is a single-layer rectangle, the light transmittance of the light-proof device plastic sheet is about 40%, the light transmittance of the middle portion (rectangle) and the light transmittance of the lower left portion (inverted trapezoid) are both about 15%, and the lower right portion is an unshielded regular trapezoid. The device is installed on a front windshield of a cab through a magnet and an iron sheet or an elastic rope and a sucker, and is easy to install and take down. And when the human eyes slightly move up and down or left and right relative to each other behind the light-proof device, the front sight line is basically not influenced, and distance light and strong light can be avoided.

Description

Technical Field

[0001] This invention relates to the field of transportation, and in particular to a light shield that does not obstruct the view but protects against vehicle headlights and road glare while also protecting the eyes. Background Art

[0002] When driving at night, the high beams of oncoming vehicles (especially common on roads without streetlights), glare from poles, and other bright lights can occasionally cause eye strain, even blindness for a few seconds, and can be extremely dangerous. The inventor, a frequent driver himself, found that in such situations, he instinctively extended his left hand, palm outstretched, about 40 centimeters in front of his eyes (near the windshield), with the lower edge near his eye level, forearm at approximately a 45-degree angle to his hand, raised to his left. By slightly shifting his eye and hand relative to each other, he discovered that this method was very effective at blocking the high beams of oncoming vehicles, glare from poles, and other bright lights. Upon closer inspection, a boundary line was found along the lower edge of the arm and palm, separating harmful and useful light. Above this line, most of the light was harmful, with a small portion being useful; below the line, a small portion was harmful, with most being useful. However, one cannot keep their hand raised constantly while driving, and since the palm and arm are completely opaque, some useful light was also blocked. Therefore, based on this principle, a light shield similar to a hand or arm but with varying degrees of light transmittance in different areas was developed and installed on the windshield of the driver's cab. During normal driving, there is essentially no obstruction. When encountering high beams or glare, the driver's eyes can be slightly moved up and down or left and right behind the light shield to avoid the glare, while maintaining a clear view of the road ahead. Because the eyes can be protected from the glare of high beams and glare, the driver will experience greater comfort and be free from the harmful effects of strong light. Summary of the Invention

[0003] This invention provides a glare shield that does not significantly obstruct vision while protecting against vehicle headlights and glare from the road and safeguarding the eyes. It is generally used in automobiles, but can also be adapted for other vehicles with minor modifications.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A rectangular plastic sheet with a certain light transmittance is selected, and a trapezoid is cut off from its lower right corner, forming a right angle on the right side and a 45-degree angle between the left hypotenuse and the base. This trapezoid serves as the main body. Several square magnets or iron sheets are glued to the back, and several holes are punched on both sides for threading ropes. Another rectangular plastic sheet with a certain light transmittance is selected for thickening. It has the same length as the main body but is thinner and narrower. A trapezoid of the same size is cut off from its lower right corner, similar to the main body. The thickened plastic sheet is aligned and overlapped with the trapezoid and attached to the back of the main body, forming a single-layer rectangle at the top, a thickened middle rectangle, and a thickened inverted trapezoid at the lower left corner (the thickened area is the closest and strongest area of ​​oncoming high beams). The sun deflector itself is very light and magnetically attaches to a magnet on the windshield of the driver's cab. Small holes are punched on the side for easy hanging with an elastic cord onto a small, easily movable suction cup attached to the windshield of the driver's cab, making it suitable for drivers of varying heights who may occasionally need to use it. When not in use, it can be easily removed and clipped or magnetically attached to the back of the sun visor. It does not interfere with daytime driving, and can also be used for sun shading in the morning or at midday. Due to manufacturing limitations, the sun visor can also be made as a single piece, although the light transmittance will vary in different areas. The primary purpose of the sun visor is sun protection; therefore, some wear and dirt after use will not significantly affect its functionality. Attached Figure Description

[0009] See attached diagram.

[0010] Select a rectangular plastic sheet with approximately 40% light transmittance, a thickness of 0.5mm, a length of 35cm, and a width of 21cm. Cut a trapezoid from its lower right corner, with the right side at a right angle and the left hypotenuse at an angle of approximately 45 degrees to the base (the upper side of the trapezoid is 15cm long, the height is 8cm, and the lower side is 23cm long), to create the main body 1 of the sunscreen. Make two holes (2 holes 2) with a diameter of approximately 3mm on each side of the main body 1. Select another rectangular plastic sheet with approximately 40% light transmittance, a thickness of 0.2mm, a length of 35cm, and a width of 11cm. Cut a trapezoid from its lower right corner, identical to the main body 1, to create a thickened plastic sheet 3. Align the thickened plastic sheet 3 with the trapezoidal shape and attach it to the back of the main body 1. This forms a sunscreen with a single-layer rectangle at the top, a thickened middle rectangle, and a thickened inverted trapezoidal shape at the lower left corner. Two square iron sheets (6cm x 3cm, 0.3mm thick) with a rust-resistant coating are attached to the side facing away from the driver using strong double-sided adhesive (square magnets or iron sheet 4). On the windshield corresponding to the left side of the deflector, three small magnets (2cm x 1cm, 1mm thick) are attached side-by-side using strong double-sided adhesive (magnets 5 attached to the glass). Corresponding to the right side, two small magnets (2cm x 1cm, 1mm thick) are attached. The deflector can be moved slightly up, down, left, and right relative to the magnets to adjust its position. Typically, the deflector is installed with the intersection of the lower right corner trapezoidal hypotenuse and top edge aligned with the leftmost point of the driver's left eye, and the top edge of the trapezoid at the same height as the upper eyelids. The position may vary slightly depending on the vehicle model and the driver. Two small suction cups (suction cup 6 adhering to the glass) are attached to both sides of the glare deflector on the windshield of the cab. The glare deflector can be suspended from the suction cups via an elastic cord. Another suction cup (suction cup 6 adhering to the glass) is also attached between the lower left trapezoidal area of ​​the glare deflector and the glass on the windshield of the cab. This is used to adjust the angle between the glass and the lower left trapezoidal area of ​​the glare deflector for different vehicle models, making it better suited for blocking high beams.

[0011] The above provides a detailed description of a light shield provided by an embodiment of the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
