Description

The antifog safe driving shield glass of anti-high light

The utility model relates to a kind of anti-high light that has, anti-thorn, dazzling light, the shield glass of high-visibility and haze-penetrating capability.

The world today, though the appearance of automobile of short duration a flash only in historical long river so far, its development be rapidly surprising, and deeply have influence on people's work, various fields in life.Yet along with the development and the widespread use of automobile, the traffic accident accident is also comed one after another, and is the trend of being growing on and on, and the great prestige of the safety formation association to people's lives and properties suffers heavy losses.And in all accidents, be subjected to weather effect, as daytime burning sun or other thorn dazzle; The interference of the strong car light in opposite at night; The ratio that traffic accident overcast and rainy, that the greasy weather causes factors such as sight line interference accounts in the traffic accident accident is big especially.For a long time, people thirst for solving the hang-up of this traffic safety, but proven technique is not arranged always.

The purpose of this utility model is to propose a kind of function that had both had the orthodox car Windshield, and anti-high light is arranged again, and anti-thorn, dazzling light have high-visibility and haze-penetrating capability, shield glass that can both safe driving under various weather conditions.

The purpose of this utility model is achieved in that this Windshield is to be used for inner face, outside or the inside and outside two sides that automobile front wind screen comprises tempering, interlayer, various optics funeral broker glass sheet such as common in tradition, with advanced person's coating technique and technology, and plated underlayer SnO ₂Film, top layer plating MgF ₂Film is elaborated multilayer film and is formed.Bottom SnO ₂Thickness can be 150～300nm, top layer MgF ₂Thickness is 80～120nm.

The utility model for increasing its back vision function, can also be made plating Al or plating Ag back mirror respectively on the left and right edge of described front windshield outside, back mirror is wide to be 5～20cm, and height is 20～50cm.

The utility model does not change shape, the size of original various Windshield, does not influence vehicle structure, does not influence driver behavior, and the key technical indexes is: ultraviolet rejection rate reaches 100%; Infrared ray decay 90%; Thorn, dazzling light are decayed more than 75%; Visible light transmissivity reaches 90%.Therefore, the utlity model has following good effect: both prevented of interference, the injury of various harm rays, high-visibility and haze-penetrating capability arranged again eyes, make automobile driver be not subjected to various weather conditions and night the opposite car light influence, safety traffic.This is for realizing safe driving, and the generation that reduces or avoid traffic accident is of great immediate significance.The utility model is applicable to various large, medium and small type automobiles, car, lorry, and other self-propelled vehicle that front windshield was housed originally.

Description of drawings: Fig. 1 is the structure principle chart of the utility model plating film on inner face, and Fig. 2 is the equal plated film in the inside and outside two sides of the utility model, and is coated with the structure principle chart of Al or Ag back mirror on left and right two edges, outside, among the figure, and 1-optics funeral broker glass sheet, 2-SnO ₂The plated film layer, 3-MgF ₂The plated film layer, 4-plating Al or plating Ag rear view mirror.

Embodiment 1, with reference to Fig. 1, with the optics funeral broker glass sheet 1 that has been shaped, adopt coating technique, at the inner face of glass sheet 1, plate the thick SnO of bottom 150～300nm ₂Film 2 and plate the thick MgF of top layer 80～120nm ₂Film 3.

Embodiment 2, with reference to Fig. 2, with the optics funeral broker glass sheet 1 that has been shaped, adopt coating technique, plate the thick SnO of bottom 150～300nm respectively in the inner face and the outside of glass sheet 1 ₂Film 2 and plate the thick MgF of top layer 80～120nm ₂Film 3 adopts silver mirror method to make silverskin catadioptre 4 respectively then on the edge, the left and right sides, outside of glass sheet 1, the wide 25cm of catadioptre, and height is 40cm, present embodiment, except that the function with embodiment 1, two metallic-membrane plating reflectors about establishing increase back vision function.
