Description
Technical field
The present invention relates to vehicle glass electric-heating technology field, be specifically related to the even electrically heated automobile sandwich-glass of rain brush resting position.
Background technology
At present, under arctic weather, on vehicle glass, often easily frosting is frozen, affect the sight line of people in automobile, particularly windshield glass of automobile must provide the good visual field to driver, the safety and comfort that guarantee is driven, so just necessarily requires automobile wind shield glass to have the function of defrosting ice-melt.The function of this defrosting ice-melt can by carrying out electric heating realization to automobile sandwich-glass, at present more often by the electric-heating technology used, be electric current is heated by the heating element be laminated in automobile sandwich-glass and improves the temperature of automobile sandwich-glass, thus reach the function of defrosting ice-melt.Conventional heating element has two kinds, and the first is metallic conduction silk, particularly ultra-fine metal tungsten wire, and the second is electro-thermal coatings.The former problem is that driver in car and passenger can know and sees these filaments, and the existence of these filaments can affect aesthetics and can cause interference to the visibility of laminated glass.By contrast, electro-thermal coatings is used more to favor by client as heating element.
Current many companies are all in the research carrying out heatable electro-thermal coatings laminated glass, such as US Patent No. 6472636 (B1) discloses a kind of Silver-based low emissivity film that adopts as the method for heating element, be directed in this layer in order to hot-fluid will be added, the electric current current collecting tracks (these electric current current collecting tracks are often also referred to as bus) of usual some beam shapes of use, the current collecting tracks of these beam shapes is generally printing silver slurry or metal foil film strips etc. and has low-resistance material.Have as in the tectal rectangular shape of transparent surface of heating element or the electric heating glass pane of rectangular shape, by such setting, this adds hot-fluid and roughly circulates uniformly across whole zone of heating, and therefore this zone of heating is all heated in mode uniform on this whole surface.
As everyone knows, general automobile front windshield is up-narrow and down-wide trapezoidal design substantially, plate zone of heating shape also for trapezoidal, in such shape zone of heating, the density of the electric current of zones of different has different values according to the setting of motor and the part width in heating field, therefore the position, top of this glass pane can be subject to stronger heating than the position, base of this glass pane, if wish to make glass pane position at the longer limit place of this glass pane by stronger heating, to prevent the rain brush arranged at this position in winter from freezing, some then should be taked to design especially.
One section of German patent DE 69226995 (T2) describes a kind of heated glazing of laminated glass form of automobile, the creation aspect of this invention is to have the transparent surface coating as thermal resistance and two electric current current collecting tracks be connected with this cover layer, heating field is defined between this current collecting tracks, wherein also be provided with three current collecting tracks parallel with the first and second current collecting tracks, heating field perpendicular to the sense of current in heating field, and is divided into two heating fields separated by the 3rd current collecting tracks.One in two heating fields main viewing area being arranged in this laminated glass, another heating field is used as the heating element of the resting position of rain brush.Effective heating of rain brush resting position can be realized by this design, but this design has the following disadvantages, residing for rain brush resting position, the height in heating field is less, resistance between its current collecting tracks is also less relative to the resistance in the heating field in viewing area, thus in the region of this glass pane, reach larger special power.If two heating lines are by common voltage supply, then crossing in the resting position of this rain brush can be caused to heat.If avoid this problem, need point open voltage supply of two heating fields, but which increase difficulty or the complexity of Car design, be difficult to accept by client.
One section of Chinese patent CN02824670.5 describes another heated glass window, this invention builds an auxiliary heating district in addition except primary vision area, it is characterized in that, article at least two, in the current collecting tracks of other current collecting tracks perpendicular to heating, and it at least one is connected with the current collecting tracks of primary vision area, simultaneously at least one other current collecting tracks is not connected with current collecting tracks, and it arranges cut-off rule, utilizes this design to reach the object preferentially heating rain brush resting position region.But the method joint quantity is many, be not suitable for the glass having radian.For the rectangle that windshield glass of automobile is not rule usually, heating region with arc is similar to and regards as " trapezoidal " or " fan-shaped ", can know that microcephaly position bus is short, its electric current travel path is short, and major part position bus is long, and its electric current travel path is long, its path length, resistance is large, and when voltage is certain, heating effect is poor.Therefore the effect that heating is uneven can be produced; This phenomenon is particularly evident in the rain brush resting position thermal treatment zone, and it often occurs a part defrost in defrost process, and another part does not still have defrost, and for client uses, it is not received.
