Description
Technical field
The present invention relates to vehicle glass electric-heating technology field, be specifically related to a kind of automobile interlayer electrically heated glass with vertical line transition region.
Background technology
At present for automobile front windshield, heating means on the market roughly have 2 kinds:
1, by silk screen printing, argentiferous conducting solution (being referred to as " silver slurry ") can be printed on then roasting on glass below, utilize the modes such as welding or stickup to be electrically connected, connecting power positive cathode makes electric current pass through, and reaches the effect of heating.Known, it has been widely used in rear windscreen of car glass, and for windshield glass, the method is only applicable to the heating of wiper region, because national Specification does not allow the thing outside containing heater strip in primary vision area, therefore the method is not suitable for whole heating;
2, by laying very thin tungsten filament to realize on glass, laying at least two conductive strips that conflux simultaneously, reaching same heating effect;
Known, existing wire-holding technique is also widely used in windshield glass of automobile, but in the process of running at high speed, due to long driving, it can cause visual fatigue; And heated by tungsten filament, line heating can only be realized, heating even not, and its manufacture craft more complicated;
Current many companies are all carry out can the research of electric conduction of heating rete laminated glass, and such as pertinent literature CN102555354A, CN102515562A, CN102529212A, CN102515562B discloses a kind of Silver-based low emissivity film that adopts as the method for heating element.Known existing automobile wind shield glass is all interlayer, and therefore rete can be plated in wherein on one deck glass.Wherein conductive film layer is at least connected with conductive strips, and conductive strips are generally to fire after stanniferous conductor silver solution is printed and form, after be referred to as " bus ".Sometimes also lay containing the metallic foil such as aluminium, copper on bus, reach the effect reducing resistance, thus avoid voltage loss herein." bus " is connected with power positive cathode, thus realizes being incorporated in rete of uniform current, thus realizes the heating to rete.More aesthetic feeling is had in order to make laminated glass, " bus " hides by the opaque covering bar of usual use, utilize rete normal deicing defrosting under the vehicle-mounted voltage conditions of 14V for reaching, the resistance of rete needs relatively little, general rete resistance <1 Ω/.
Known by rete heating can be calculated by unit thermal power, wherein formula P=U2/ (RS × H2), wherein U is input voltage, for automobile, it is vehicle-mounted voltage, is generally 14V, RS is the surface resistance of rete, and H is the distance between two buses.
Maximize for realizing P, known U is vehicle-mounted voltage, for constant, when RS is certain, should shorten H as much as possible, known glass is usually long-range how a lot of than wide again, so usually lay bus below along the upper of glass, thus the effect shortening H can be reached.
For reaching more uniform heating effect as much as possible, two " buses " are roughly parallel in laying.
Be directed to the rectangle that vehicle glass substrate is not generally rule, usually after entrucking near that of engine, be referred to as " major part ", relative is other, is referred to as " microcephaly ".Generally speaking the major part of vehicle glass substrate is usually long than microcephaly, when same laying bus, " major part " limit is often than " microcephaly " length of side, and institute thinks that to reach concentric reducer temperature consistent, and ratio " microcephaly " position, " major part " position needs to consume more power; Namely, when normal power-up, the temperature of " major part " position is all low than the temperature of " microcephaly " position.It by changing the width of bus or using the bus material of different resistivity to obtain different resistance values, carries out reaching certain improvement effect usually.The resistance value of bus should be tried one's best low to reduce voltage loss herein on laying.
A kind of windowpane is described in patent DE1256812B1, this windowpane reaches the effect of heating by successive sedimentation metal or metal oxide, the present invention is intended to the problem that solution high resistance brings, and this resistance is about 200 Ω/, and it is not suitable for vehicle-mounted voltage.For meeting the good heating effect of low-voltage, its rete resistance should be as far as possible little, and this needs the thickness increasing metallic diaphragm or metal oxide rete, and the increase of thicknesses of layers then can cause the reduction of transmitance.Have pertinent literature to record to be heated after vehicle-mounted boost in voltage for front by extra transformer, but the method buys transformer needs extra-pay, and need to carry out certain repacking to vehicle in installation process, be unfavorable for that client accepts, be therefore difficult to promote.
Provide the method for one and half resistance areas in patent CN200580042596.0, by building low-resistance region volume mode, reaching the effect shortening thermal treatment zone height H, thus heating effect is provided.But half resistance area that the method builds directly is connected with upper and lower busbar by many transition strips, and contact with rete, when providing enough electric current, still having sub-fraction is not that the electric current of wishing is heated by rete inflow primary vision area, can cause a fraction of current loss.
Existing routine techniques is by building half resistance area be connected with Up Highway UHW or Down Highway, half resistance area forms by organizing transition strips more, transition strips is directly connected with Up Highway UHW or Down Highway, the method wishes that the transition strips by building indirectly plays the effect shortening primary vision area H, thus improve the object of primary vision area heating effect, but the method rete directly contacts with transition region, and directly contact with Up Highway UHW and/or Down Highway, electric current is through transition region, still there is sub-fraction electric current to pass through from rete, cause damage, extraordinary heating effect cannot be played to primary vision area.
