Abstract
The invention relates to a frost and fog prevention device for the window of a motor vehicle, belonging to the technical field of automobile. The frost and fog prevention device comprises window glass, wherein a transparent sealing device internally filled with gas is attached to the inner surface of the window glass. The frost and fog prevention device disclosed by the invention has the advantages of being simple in structure, easy in replacement and detachment, small in thickness, capable of compressively deforming without effecting the normal lifting of the window, low in cost and the like, and can avoid a problem of steam condensation caused by the direct contact of moist and hot air in the vehicle and the cold window glass, thus efficiently preventing the occurrence of a case of the influence on the sight in the vehicle due to the frosting and fogging phenomena of the window.
Description
Technical field
The present invention relates to a kind of motor vehicle windows system associated components, relate in particular to a kind of motor vehicle windows demisting system, belong to automobile technical field.
Background technology
For the motor vehicles that in low temperature environment, use, as winter with car and the north usually can face following problem than cryogenic region with car:
1, because the vehicle internal-external temperature difference is bigger, and ambient temperature is lower, and vehicle interior temperature is higher and relative humidity is big; Cause the inboard frosting of vehicle window or haze; Have a strong impact on driving vision on the one hand, bring potential safety hazard, also influenced riding comfort on the other hand to driving;
2, excessive when the vehicle internal-external temperature difference, the passenger even the vehicle front and rear windows is equipped with defrost system or heater, also can't thoroughly eliminate the vehicle window frosting and the phenomenon that hazes more for a long time;
3, the side vehicle window of general vehicle all can not be equipped with antifog, defrost system, so side window inevitably can haze or frosting.
Summary of the invention
The object of the invention is exactly to the problems referred to above, and a kind of motor vehicle windows demisting system is provided.
Technical scheme of the present invention is: it comprises glass for vehicle window, and the transparent sealing device of gas is housed in described glass for vehicle window inner surface is covered with.
Further, described transparent sealing device comprises two-layer transparent material layer, between the two-layer transparent material layer gas is housed, and is tightly connected between the two-layer transparent material layer.
Further, described transparent sealing device is bonded in the glass for vehicle window inner surface.
Further, be provided with fluid sealant or band between described transparent sealing device periphery and the glass for vehicle window inner surface, transparent sealing device envelope is bonded on the glass for vehicle window.
The present invention has simple in structure; Be easy to replacement and removal; Thinner thickness, compressible distortion do not influence normal up-down of vehicle window and low cost and other advantages, can avoid the glass for vehicle window surface that damp-heat air is direct and ice-cold in the car directly to contact; The problem that causes steam to condense, thus the vehicle window frosting effectively prevented, situation that the phenomenon that hazes influences sight line in the car takes place.

Fig. 2 is an A-A cutaway view of the present invention.
Wherein, 1-glass for vehicle window; 2-gas; 3-transparent sealing device; 4-adhering device.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
As depicted in figs. 1 and 2, it comprises glass for vehicle window 1, and the transparent sealing device 3 of gas 2 is housed in glass for vehicle window 1 inner surface is covered with; Transparent sealing device 3 comprises two-layer transparent material layer, and gas 2 is housed between the two-layer transparent material layer, forms the gas transition zone; Gas 2 is air; Be tightly connected between the two-layer transparent material layer, transparent material can adopt (lucite, plastics), and transparent sealing device 3 is bonded in glass for vehicle window 1 inner surface through adhering device 4; Adhering device 4 is fluid sealant or band, and transparent sealing device 3 envelopes are bonded on the glass for vehicle window.Thereby prevent that effectively air damp and hot relatively in the car from directly contacting ice-cold glass for vehicle window surface suddenly, thereby the phenomenon that condenses into frost, mist takes place.
Principle of the present invention is: utilize the relatively poor characteristics of air thermal conductivity.When not having the gas thermal insulation layer that this invention adopts; Cause the glass for vehicle window internal surface temperature to descend because ambient temperature is low thereupon; And when hot and humid gas touches the lower vehicle window inner surface of temperature in the car, cause steam wherein to condense rapidly, thereby frosting or haze; After adopting the gas thermal insulation layer; Because the poor thermal conductivity of air; Even outside environment temperature is lower,, make vehicle window inboard film temperature and environment inside car temperature be more or less the same because the insulating effect of gas is arranged; Therefore steam is difficult to condense above that, thus the generation of frosting or the phenomenon that hazes on the vehicle window of avoiding.
The present invention can guarantee that also motor vehicle can remove without demisting system the time.
Claims (4)
