Description
Technical field
The present invention relates to vehicle glass electric-heating technology fields, and in particular to the electrical heating automobile interlayer with shunting busbar
Glass.
Background technology
The present invention relates to the windshield of a kind of laminated glass, especially vehicle, side window glass, back windshield, skylights
Glass.This glass allows the glass pane of a piece of monolithic to pass through a kind of transparent plastic such as polyvinyl butyral（PVB）With another
The windowpane of monolithic is bonded together.
It is directed to automobile front windshield at present, heating means on the market substantially there are 2 kinds：
1, by silk-screen printing by the electrically conductive solution of argentiferous（It is referred to as below " silver paste "）It is printed on glass and then roasts,
It is electrically connected in the way of welding or stickup etc., connecting power positive cathode makes electric current pass through, and achievees the effect that heating.It is known that
It has been widely used for rear windscreen of car glass, and for windshield glass, this method is only applicable to the heating of wiper region,
Because national Specification be not allow for containing heater strip in primary vision area except thing, therefore this method is not suitable for whole face
Heating.
2, it is realized by laying very thin tungsten filament on glass, while laying at least two confluence conductive strips, reach same
Sample heating effect.
It is known that existing wire-holding technique is also widely used in automobile wind shield glass, but during running at high speed, due to
It is prolonged to drive, visual fatigue can be caused；And heated by tungsten filament, can only realize line heat, heating not enough uniformly,
And its manufacture craft is more complicated.Current many companies are all in the research for can heat electric membranous layer laminated glass, such as phase
Pass document CN102555354A, CN102515562A, CN102529212A, CN102515562B disclose a kind of low using silver-based
Method of the radiation film as heating element.Known existing automobile wind shield glass is all interlayer, therefore film layer can plate wherein
On one layer of glass.Wherein electric membranous layer is at least connected with a conductive strips, and conductive strips are usually that stanniferous conductor silver solution prints
Fired after system, behind be referred to as " busbar ".Sometimes it is also laid containing metallic foils such as aluminium, copper on busbar, reaches reduction electricity
The effect of resistance, to avoid the loss of voltage here." busbar " is connected with power positive cathode, to realize that electric current uniformly draws
Enter into film layer, to realize the heating to film layer.In order to make laminated glass more have aesthetic feeling, usually using opaque covering item
" busbar " is covered, utilizes film layer normal deicing under the conditions of 14V vehicle-mounted voltages to defrost to reach, the resistance of film layer needs
It is relatively small, general film layer resistance<1Ω/□.
We are known can be weighed by film layer heating by power density, wherein formula P=U2/(RS×H2), U is input electricity
Pressure, is vehicle-mounted voltage for automobile, usually 14V, RSFor the surface resistance of film layer, H be between two conductive bars away from
From.
To realize that P is maximized, our known U are vehicle-mounted voltage, are constant, in RSIn the case of certain, we should
Shorten H as far as possible, and known glass is usually long mostly many more than wide, so following arranging mother generally along the upper of glass
Line, so as to have the function that shorten H.Vehicle glass is generally not the rectangle of rule, close to engine usually after entrucking
That, we term it " major part ", opposite other one side, we term it " microcephalies ".In general vehicle glass is big
Head is usually longer than microcephaly, and in the case of equally arrangement conductive bar, " major part " side is often than " microcephaly " length of side, so to reach big
Microcephaly's temperature is consistent, and major part position needs to consume more power than microcephaly position；I.e. in the case of normal power-up, major part position
Temperature it is all lower than the temperature of microcephaly position.
The application that automotive front baffle can be heated now is more and more extensive, especially for high latitude area.It, can in high latitude area
Heating function almost becomes the preferred consideration that consumer purchases vehicle.By the above technology, heatingization ice is realized using electric membranous layer
White function can be accomplished.But this method is directed to major part, position when especially windscreen wiper item is static（It is referred to as below
For " wiper resting position heating zone "）Sufficient heat is hardly resulted in, windscreen wiper is caused because weather is subcooled in high latitude area
Item freezes, and that the example that wiper causes wiper motor to burn is opened in the case where that can not judge is numerous by consumer,
It brings big inconvenience for the use of consumer.It is mentioned in Chinese patent CN02824670.5, the other structure in addition to primary vision area
Build one auxiliary heating zone, which is characterized in that at least two other current collecting tracks in the current collecting tracks of heating, and its
At least one connect with the current collecting tracks of primary vision area, while at least one other current collecting tracks are not connected to current collecting tracks, together
When its be arranged cut-off rule, preferential heated wiper device region is achieved the purpose that using the design.
Also a kind of heatable laminated glass is referred in patent CN03817604.1, by extending to no end of bus bars
There is coating film area and eliminates hot spot to reach.
Prior art defect：Power connection setting is unreasonable, will produce hot spot.
The compound for generally utilizing the conductor silver for including tin type in the prior art is mentioned in patent CN02824670.5,
Sometimes metallic film band is also used, realizes the effect that glass " major part " position or wiper resting position heating zone are preferentially heated,
But 4 situations, in patent CN02824670.5, the setting of electrode are less than for the general connector quantity of vehicle glass（Below
We term it " power connections "）Quantity is excessive；Although referred in patent " in many cases, two it is same with lower busbar
One in the auxiliary busbar of pole can not have to be connected on power supply ", but with the proviso that " along the loss of voltage of the busbar
The value limited no more than one "；In practice it was found that reaching ideal heating effect, film using vehicle-mounted voltage 14V
Surface resistance is less than 1 ohm/, and bus bar resistance is usually not much different, if only one termination " connector ", inevitably
There is certain loss of voltage, heating effect remoter from joint location can be caused poorer, to reach uniform heating effect, under
Busbar at least needs the second busbar for being connected with two connectors, while not being connected with Down Highway in wiper resting position heating zone
It needs to connect a connector, when connector quantity is no more than 4, Up Highway UHW can only connect a connector, if it is connected in the end of busbar
Portion then will produce the non-uniform effect of heating, and can be inevitable because electric current is excessively concentrated in the end that connector is ined succession
There is hot spot, CN02824670.5 is in rain to the end of the second busbar of wiper resting position heating zone and untreated
In the film layer of curette resting position heating zone, hot spot also will produce in end.
Lead laying is unreasonable, there is the non-uniform problem of heating.
A kind of method for eliminating hot spot is referred in patent CN03817604.1, by the way that the end of busbar is extended to membrane removal
Region is to have the function that eliminate hot spot, but it draws simply by a lead, is then connected with connector, electric current row
It walks path to differ, can cause to heat non-uniform phenomenon.And do not refer to that how to solve wiper resting position adds in the patent
In hot-zone the problem of hot localised points.
