Abstract
The utility model discloses a hydrophobic mirror surface structure of an exterior rear-view mirror, which overcome a defect that the mirror surface in the prior art is short of practical significance because the mirror surface, in particular the exterior rear-view mirror of an automobile, is waterproof by using electric heating blowing; and the utility model provides the hydrophobic mirror surface structure of the exterior rear-view mirror with simple structure, low cost and good effect so as to solve a waterproof problem of the exterior rear-view mirror of the automobile. The hydrophobic mirror surface structure comprises a transparent mirror body and a light reflecting layer which is plated on the back surface; and the hydrophobic mirror surface structure is characterized in that a hydrophobic layer is compounded on the front face of the mirror body. According to the utility model, the hydrophobic layer is compounded on the front face of the mirror body, the mirror surface of the exterior rear-view mirror is kept away from water like lotus leaf and is also kept bright even in rainy days; and the hydrophobic mirror surface structure of the exterior rear-view mirror, disclosed by the invention, has a simple process, a low cost, a simple structure and almost no feeling of the increasing of volume or parts of the exterior rear-view mirror.
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 hydrophobic mirror surface structure.
Background technology
In rainy day or surface gathered water situation, the Car mirror surface of external rearview mirror is easy to be stained with water droplet or water mark.This visual field to chaufeur has a great impact, and easily causes the generation of traffic hazard situation, brings great threat to traffic safety.The water droplet or the water mark that adhere in order to remove the exterior mirror minute surface except manually wiping, can also adopt the device that is similar to front windshield windscreen wiper, but will increase like this extras such as motor, mechanism too complexity and volume is too huge, easily damages, difficult in maintenance, and increase cost; Prior art also have with the method for electro heat to dispel a mist.
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.This electrical heating method adds the method that air blowing type is removed water droplet, in fact can't practical application, because, just not saying this electrothermal structure is complicated, singly be to have the blower fan of two outlets to be connected on the outside rear-view mirror, just enough heavy, and more crucial be, want water droplet was dried up with hot blast moment, easier said than done, the heat of vaporization of water reaches 2260 kilojoule per kilogram, specific heat of water is 4.2 * 10^3 Jiao/(kilogram * ℃), in other words, make water evaporate needed heat at its boiling point and be five times in handle and wait water gaging to be heated to 100 ℃ of needed heats from 1 ℃, what the method that electric heating dries up rainwater continuous on the minute surface do not play for the situation that rainy day, outside rear-view mirror was subjected to rainwater to water pouring at all and acts on.
Summary of the invention
The utility model technical issues that need to address are, the minute surface waterproof that overcomes prior art particularly automobile outer rear-view mirror waterproof adopts electric heating to dry up the defective that lacks practical significance, provide a kind of simple in structure, automobile outer rear-view mirror hydrophobic mirror surface structure that cost is low, effective, to solve the automobile outer rear-view mirror waterproof problem.
The purpose of this utility model is achieved by following technical proposals: a kind of exterior mirror hydrophobic mirror surface structure, comprise the reflector layer that transparent mirror body and the back side thereof are coated with, and described mirror body front is compounded with water-repellent layer.
At the front of mirror body composite hydrophobic layer, minute surface is no longer got wet, the water-repellent layer structure of the water droplet one contact minute surface of rainy day becomes the globule and just rolls at once, guarantees that minute surface is bright.
As preferably, the positive compound water-repellent layer of described mirror body is that the PVB hydrophobic is processed Structural layer.
As preferably, the thickness that described PVB hydrophobic is processed Structural layer is 0.05～0.30mm.
As preferably, the thickness that described PVB hydrophobic is processed Structural layer is 0.20mm.
As preferably, described mirror surface composite hydrophobic layer is fluorine silicon coating Structural layer, and the thickness of Structural layer is 0.05～0.30mm.
The beneficial effects of the utility model are:
1, mirror body front is compounded with water-repellent layer, makes the minute surface of outside rear-view mirror as lotus leaf, drips and is not stained with, even also keep bright in the rainy day;
2, technique is simple, and is with low cost;
3, simple in structure, outside rear-view mirror does not have the increase of what volume or part.
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.
Embodiment 1: as shown in Figure 1, a kind of exterior mirror hydrophobic mirror surface structure comprises the reflector layer 1 that transparent mirror body 2 and the back side thereof are coated with, and described mirror body front is compounded with water-repellent layer 3.
The positive compound water-repellent layer of mirror body is that the PVB hydrophobic is processed Structural layer, and the thickness that the PVB hydrophobic is processed Structural layer is 0.38mm.
Also can be at the fluorine silicon coating Structural layer of the front of mirror body composite hydrophobic, the thickness of Structural layer is 0.30～0.45mm.
The utility model can use at all vehicles that is provided with back mirror, have advantages of that cost simple in structure is low effective, if those skilled in the art does simple the modification or replacement to the foregoing invention content, such change can not think to break away from scope of the present utility model, and all will be included within the scope of claim of the present utility model the apparent modification of those skilled in the art like this.
