Description
Technical field
The present invention relates to vehicle glass electric-heating technology field, and in particular to the uniform electrically heated automobile of rain brush resting position
Laminated glass.
Background technology
At present, frosting icing is tended under arctic weather, on vehicle glass, influences the sight of people in automobile,
Particularly windshield glass of automobile must provide the good visual field to driver, just can guarantee that the safety and comfortableness of driving, this
Sample just necessarily requires function of the automobile wind shield glass with defrosting ice-melt.The function of this defrosting ice-melt can be by pressing from both sides to automobile
Layer glass is electrically heated realization, the electric-heating technology being relatively frequently used at present, is to press from both sides electric current by being laminated to automobile
Heating element heater in layer glass heats and improved the temperature of automobile sandwich-glass, so as to reach the function of defrosting ice-melt.It is conventional
Heating element heater have two kinds, the first is metallic conduction silk, particularly ultra-fine metal tungsten wire, and second is electro-thermal coatings.Before
The problem of person, is the driver of in-car and passenger can be seen clearly that these filaments, and the presence of these filaments can shadow
Ring aesthetics and the visibility of laminated glass can be interfered.By contrast, using electro-thermal coatings as heating element heater more
Favored by client.
Current many companies are all carrying out the research of heatable electro-thermal coatings laminated glass, such as United States Patent (USP)
US6472636 (B1) disclose it is a kind of using method of the Silver-based low emissivity film as heating element heater, in order to will heating stream guiding
Into the layer, usually using the electric current current collecting tracks of some beam shapes（These electric current current collecting tracks are also frequently referred to as mother
Line）, the current collecting tracks of these beam shapes are usually to print silver paste or metallic film band etc. to have low-resistance material.With
In the rectangular shape of transparent surface coating as heating element heater or the electrical heating glass pane of rectangular shape, pass through this
The setting of sample, the heating stream are substantially evenly circulated by whole zone of heating, and the zone of heating is therefore with equal in the whole surface
Even mode is all heated.
It is well known that in general automobile front windshield is substantially up-narrow and down-wide trapezoidal design, the shape of zone of heating is plated
Shape is also to be trapezoidal, and the density of the electric current of different zones is according to the setting of motor and the part in heating field in such shape zone of heating
Width and there is different values, therefore the top position of the glass pane can than the glass pane base position by stronger plus
Heat, if it is desired to make glass pane position at the longer side of the glass pane by stronger heating, to prevent in winter
Frozen in the rain brush that this position is set, then some should be taken particularly to design.
One German patent DE 69226995 (T2) describes a kind of heated glazing of the laminated glass form of automobile,
It is in terms of the creation of the invention with transparent surface coating and two electricity being connected with the coating as thermal resistance
Current collecting tracks are flowed, heating field are defined between the current collecting tracks, wherein being also provided with parallel with the first and second current collecting tracks
The 3rd current collecting tracks, the 3rd current collecting tracks are divided into two perpendicular to the sense of current in heating field, and by heating field
Individual separated heating field.One in two heating fields is located in the main viewing area of the laminated glass, another heating field
The heating element heater of resting position as rain brush.Effective heating of rain brush resting position can be realized by this design, but
This design has the following disadvantages, because the height in heating field residing for rain brush resting position is smaller, between its current collecting tracks
Resistance is also smaller relative to the resistance in the heating field in viewing area, so as to reach bigger spy in the region of the glass pane
Other power.If two heating lines can cause the mistake in the resting position of the rain brush by common voltage supply
Heating.Need to separate voltage supply to two heating fields if avoiding this problem, but so add Car design
Difficulty or complexity, it is difficult to be received by client.
One Chinese patent CN02824670.5 describes another heated glass window, the invention in addition to primary vision area in addition
Structure one auxiliary heating zone, it is characterised in that at least two other current collecting tracks in the current collecting tracks of heating, and
It at least one is connected with the current collecting tracks of primary vision area, while at least one other current collecting tracks are not connected to current collecting tracks,
It sets cut-off rule, and the purpose in preferential heating rain brush resting position region is reached using the design.But this method piece-ups
Amount is more, is not suitable for cambered glass.It is not usually the rectangle of rule for windshield glass of automobile, by adding with arc
Thermal region approximation regards " trapezoidal " or " sector " as, it is known that microcephaly position bus is short, its electric current travel path is short, and major part position
Bus length is put, its electric current travel path length, its path length, resistance is big, and in the case where voltage is certain, heating effect is poor.Therefore
It can produce and heat uneven effect；The phenomenon is particularly evident in rain brush resting position heating zone, and it is past during defrost
It is past that a part of defrost occurs, and another part does not still have defrost, it is not received for client's use
's.
