Abstract
The utility model discloses an antifogging light-weight mirror surface structure of an exterior rearview mirror. The antifogging light-weight mirror surface structure overcomes defects of large mass and unpractical waterproofing measures existing in the exterior rearview mirror in the prior art, and provides the antifogging light-weight mirror surface structure of the exterior rearview mirror having the advantages of simple structure, light weight, less cost and obvious effect. The mirror surface structure comprises a transparent mirror body and a reflective layer coated on the back side of a mirror body, the mirror body is a plane mirror made of an optical plastic having density smaller than 1.40 g.cm to 3 g.cm, the front side of the mirror body is compounded with a water-repellent layer. The mirror surface structure has a simple structure, except that the front side of the mirror body is compounded with the water-repellent layer, the mirror surface structure is same as that of the mirror body in the prior art; the mirror surface structure has reduced weight and meets a requirement of light weight; and has less cost and an obvious waterproofing effect; and has a stronger impact resistance ability than that of glass, thereby avoiding a phenomenon that the mirror surface structure is broken by hard objects.
Description
Technical field
The utility model belongs to the automobile outer rear-view mirror technical field, is specifically related to a kind of exterior mirror preventing water drops weight-saving structure.
Background technology
In rainy day or surface gathered water situation, the minute surface of eliminating automobile external back mirrow is easy to be stained with water droplet, and this visual field to chaufeur has a great impact, and easily causes the generation of traffic hazard situation, brings great threat to traffic safety; Secondly, though exterior mirror glass is little, but its quality is also more than 200-300g, under the prerequisite of assurance function, alleviate the quality of exterior mirror glass, also be a latency of automobile lightweight, and prior art is given and consideration the waterproof of outside rear-view mirror mostly, and for the lightweight of outside rear-view mirror attention not.
China Patent No. ZL200420067070.0 for example, name is called the utility model patent of " warm-air type exterior mirror ", a kind of warm-air type exterior mirror is disclosed, comprise eyeglass, shell, ventilation inlet, airduct, switch, blower fan, also comprise hot-blast outlet, cold wind outlet, heating wire, hot blast import, cold wind import, hot blast layer and cold wind layer; This warm-air type exterior mirror utilizes the power supply of self-propelled vehicle to heating wire and blower fan power supply; Blower fan can be the blower fan of former car, also can be the blower fan of autogamy, and the wind that it is confessed is punished into two parts at ventilation inlet, and a part directly blows out from the cold wind outlet, and the direction of wind is downward, turns over to prevent that water from dripping from the bottom of back mirror; Another part becomes hot blast through heating wire, blows out from hot-blast outlet, and hot-blast outlet is a plurality of outlets, and what blow is the water droplet that has been stained with on the minute surface, makes mirror surface cleaning; When self-propelled vehicle was travelled in the rainy day, can not form the globule and water curtain on the back mirror outside the car, make the sight line of chaufeur clear.This set hot air apparatus dries up the method for rainwater on the outside rear-view mirror itself just may not be effective, but also will add this many parts, and outside rear-view mirror be can't bear the heavy load.
Summary of the invention
The utility model technical issues that need to address are, the outside rear-view mirror that overcomes prior art exists that quality is large, the unpractical defective of waterproof measure, provides that a kind of simple in structure, weight saving, cost are few, the automobile outer rear-view mirror preventing water drops lightweight minute surface structure of successful.
The purpose of this utility model is achieved by following technical proposals: a kind of exterior mirror preventing water drops lightweight minute surface structure, comprise the reflector layer that transparent mirror body and the back side thereof are coated with, and described mirror body is less than 1.40g.cm by density
-3The plane mirror made of optical plastic, mirror body front is compounded with water-repellent layer.
The main photometric characteristics of optical plastic is that transparent rayless scattering, the shock-resistant ability of impact-resistant energy force rate glass are strong, and shop characteristic is good, but injection mo(u)lding; The density of optical plastic is little, only has half of silicate glass density, can alleviate the weight of outside rear-view mirror; At mirror body front composite hydrophobic layer, make minute surface as lotus leaf, water droplet one contact on rainy day is smooth and mistake is not deposited any vestige.
As preferably, the plane mirror of described mirror body for being made by polymethyl methacrylate (PMMA) or modified poly (methyl methacrylate) (372).
The penetrability of PMMA is high, and Maximum CW lasing temperature reaches 92 ℃, satisfies the service conditions requirement of outside rear-view mirror; The copolymer of PS modified PMMA wherein can forming thin-walled, good stability; Under the condition of equal impact resistance even thinner than glass mirror; Density 1.17-1.2 only has half of simple glass; Certain heat-resisting resistance to cold is arranged, and mechanical property is higher.
As preferably, described water-repellent layer is that the PVB hydrophobic is processed Structural layer.
As preferably, the thickness that described PVB hydrophobic is processed Structural layer is 0.30～0.45mm.
As preferably, the thickness that described PVB hydrophobic is processed Structural layer is 0.38mm.
As preferably, described water-repellent layer is fluorine silicon coating Structural layer, and the thickness of Structural layer is 0.30～0.45mm.
The beneficial effects of the utility model are:
1, simple in structure, just at mirror body front composite hydrophobic layer, mirror structure is the same with the mirror body of prior art;
2, weight saving meets the weight-saving requirement;
3, few, the anti-successful that gets wet of cost;
4, stronger than the shock-resistant ability of glass, avoiding hard thing one to bump is that broken phenomenon occurs.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Among the figure, reflector layer 1; Mirror body 2; Water-repellent layer 3.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiments the utility model is further described.
