Abstract
A kind of windshield, including the first glassy layer, PVB films, metal net layer and the second glassy layer；Metal net layer and the PVB film is between the first glassy layer and the second glassy layer；First glassy layer and the second glassy layer periphery plastic edge combined thereon when once shaping；The metal net layer is adhesively fixed in the first glassy layer or the second glassy layer.The utility model between the first glassy layer and the second glassy layer by setting metal net layer so that metal net layer, which absorbs part, will enter the electromagnetic radiation of drivers' cab, so as to reduce the indoor electromagnetic radiation of driver.Anticollision performance is greatly improved.
Description
Technical field
It the utility model is related to the technical field of glass, more particularly to a kind of windshield.
Background technology
With the fast development of high ferro, the EMU speed of service greatly improves, and not only increases transport efficiency, shortens
The travel time of passenger, and make the exchanges such as economy between city, culture, trade more frequent.But given in EMU
While people offer convenience, due to EMU in high-speed cruising with the fluid-structure coupling system such as air, contact net, line track
Between interaction aggravation, the electromagnetic radiation that drivers' cab is passed to by windshield is significantly increased, and EMU driver is long-term
Work in drivers' cab, be subject to the serious pollution of electromagnetic radiation, and the anticollision performance of windshield is also required to improve.
The content of the invention
A kind of windshield is provided the purpose of the utility model is to overcome the above-mentioned deficiency of the prior art, with motor-car
In group operational process, the indoor electromagnetic radiation of driver is reduced, anticollision performance improves.
The technical solution of the utility model is：Including the first glassy layer, PVB films, metal net layer and the second glassy layer；It is described
Metal net layer and PVB films are between the first glassy layer and the second glassy layer；First glassy layer and the second glassy layer periphery
Plastic edge combined thereon when once shaping；The metal net layer is adhesively fixed in the first glassy layer or the second glassy layer.
The metal net layer is made of copper or aluminium.
A diameter of 0.02mm of wire in the metal net layer, the spacing of adjacent wire is 1.6mm.
First glassy layer and the second glassy layer are chemically toughened glass layer.
The thickness of first glassy layer and the second glassy layer is 7mm.
The thickness of the PVB films is 3mm.
The beneficial effects of the utility model are：By setting metal mesh between the first glassy layer and the second glassy layer
Layer so that metal net layer, which absorbs part, will enter the electromagnetic radiation of drivers' cab, so as to reduce the indoor electromagnetic radiation of driver.
Anticollision performance is improved.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure, the 1, first glassy layer, 2, PVB films, 3, metal net layer, 4 and second glassy layer, 5, plastic edge.
Embodiment
In Fig. 1, a kind of windshield, by setting metal net layer 3, gold between the first glassy layer 1 and the second glassy layer 4
Belong to stratum reticulare 3 and absorb the electromagnetic radiation that will partly enter drivers' cab, to realize the reduction of the indoor electromagnetic radiation of driver.First glass
1 and second glassy layer of glass layer, 4 periphery plastic edge 5 combined thereon when once shaping so that the impact resistant of the utility model
Performance is improved.Metal net layer 3 and PVB films 2 are between the first glassy layer 1 and the second glassy layer 4.Metal net layer 3 can be with
It is adhesively fixed in the upper surface of the second glassy layer 4.At this time, PVB films 2 are adhesively fixed in the lower surface of the first glassy layer 1.Metal mesh
Layer 3 can also be adhesively fixed in the lower surface of the first glassy layer 1.PVB films 2 are adhesively fixed in the upper surface of the second glassy layer 4.Gold
Belong to stratum reticulare 3 to be made of high metal materials of electrical conductivity such as copper or aluminium.A diameter of 0.02mm of wire, phase in metal net layer 3
The spacing of adjacent wire is 1.6mm.The thickness of metal net layer 3 is 0.8mm.First glassy layer 1 and the second glassy layer 4 are chemistry
Toughened glass layer.The thickness of first glassy layer 1 and the second glassy layer 4 is 7mm.The thickness of PVB films 2 is 3mm.PVB films 2 and gold
Air layer is equipped between category stratum reticulare 3.The thickness of air layer is 2mm, and air layer is argon gas blanketing.The utility model can be applied at a high speed
EMU, protects driver to be acted on from extraneous aerodynamic loading pressure, gravel impact, solar irradiation etc. in EMU high-speed cruising
While, also to meet the requirement of antinoise and electromagnetic radiation.
