From above-mentioned table 1: on market most of vehicle rear windshield left and right directions on black surround width be all greater than 50mm, and after have employed technical scheme of the present invention, black surround width reduces only 30mm, thus extend at least 40mm(and 40=2 × (50-30) in the lateral direction) width so that chaufeur obtains wider field range.
2, homogeneous heating
When being eliminated the fog, sleet etc. on vehicle window by heater wire array 1, user obviously wishes that all sites on vehicle window all realizes comparatively average heating effect more, instead of part drying and another part still snow and ice cover.Therefore, in order to realize the homogeneous heating to each several part on vehicle window, i.e. the equilibrium of each heater wire in heating efficiency, the invention allows for further improvement, is described below in conjunction with Fig. 3.
Fig. 3 shows the schematic diagram of heater wire width according to an embodiment of the invention.
As shown in Figure 3, in heater wire array 1 according to an embodiment of the invention, if power supply buses is arranged at lower frame place and using the upper side frame of vehicle window and left and right side frame (the residue frame namely except lower frame) as outer rim, all heater wires then in heater wire array 1 are arranged in order to described outer rim according to the midway location of order from short to long from lower frame, and be greater than near the width of peripheral heater wire of outer rim the width enclosing heater wire in the midway location of lower frame, namely the width of every bar heater wire and its length are proportionate.
When adjusting its width according to the length of heater wire, in fact have adjusted the resistance of heater wire, and make the resistance of all heater wires in heater wire array 1 equal as much as possible, or within the scope of certain error, allow the resistance difference between each bar heater wire to be less than preset difference value (the concrete numerical value of this preset difference value can be determined according to the actual requirements).Particularly, in such as Fig. 3, when the length of heater wire changes from short to long, the width of each heater wire changes from 0.65mm to 0.95mm, then when the resistance of each bar heater wire is equal or close, cal val after making it be energized is close, thus on whole vehicle window, realize comparatively uniform heating effect.
3, obstruct the view is avoided
In technique scheme, in order to carry out homogeneous heating to vehicle window, the width of heater wire being adjusted, making its width of heater wire of more growing also larger.But heater wire non-transparent material, then wide heater wire easily hinders the sight line of chaufeur.
Therefore, the problem of obstruction may be caused for wider heater wire for the sight line of chaufeur, and in order to ensure not affecting the effect of homogeneous heating, present invention further proposes following technical proposals, be described in detail below in conjunction with Fig. 4.
When chaufeur observes peripheral vehicle situation by vehicle window, its sight line is not identical for the demand in each region of vehicle window.For the rear windshield of automobile, chaufeur is primary vision area in the rear windshield region paid close attention to a greater extent, and the rear windshield region that chaufeur is not paid close attention to or not extremely paid close attention to is non-primary vision area.In one embodiment, described primary vision area is central authorities and the upper section of rear windshield, but not primary vision area is the remainder of rear windshield, the such as part such as the lower left corner, the lower right corner.Described primary vision area described in each embodiment of the present invention and non-primary vision area all can with reference to foregoing descriptions.Really, this primary vision area and non-primary vision area also can change according to the different situations (such as height, height of seat and seating position etc.) of chaufeur or passenger.
Therefore, according to the actual demand of chaufeur, Region dividing can be carried out to the vehicle window of automobile.Particularly, Fig. 4 shows the schematic diagram arranging heater wire width according to vision area distribution according to an embodiment of the invention.
As shown in Figure 4, carrying out on the basis of Region dividing according to vision area distribution to vehicle window, can realize further adjusting to the width of heater wire: every bar heater wire comprises the Part I of the primary vision area being positioned at described vehicle window and is positioned at the Part II of non-primary vision area, and the width of Part I is less than the width of Part II.
Such as the shortest heater wire 10 shown in Fig. 4, its width being positioned at the part of primary vision area is 0.5mm, and the width of remainder is 0.65mm, therefore, by adopting different in width to the part be in every bar heater wire in different vision area, both achieved and the resistance of each heater wire had been adjusted, and reduced again heater wire as far as possible and the sight line of user in primary vision area is hindered.
4, the shape of heater wire
Heater wire can take arbitrary shape, such as preferably, when the lower frame place of described vehicle window is provided with described power supply buses, the shape of heater wire can be consistent with the shape of the outer rim of described vehicle window, arranges like this and will the effect of heatable vehicle window be made better.
Such as rectangle (or being similar to rectangle) vehicle window as shown in Figure 2, because power supply buses is arranged at the lower frame place of vehicle window, then outer rim is in " П " type, and the shape of the every bar heater wire namely in heater wire array 1 also can be " П " type.Wherein, when Region dividing is carried out according to vision area distribution to vehicle window for needs, can the horizontal component in " П " type heater wire be in described primary vision area, vertical portion is in outside described primary vision area.
Certainly, it will be understood by those skilled in the art that the concrete shape of heater wire can be arranged according to vehicle window shape.Such as curved vehicle window, if make the shape of heater wire match with vehicle window, correspondingly can adopt the heater wire of arc, thus make the overall appearance on vehicle window more consistent.Wherein, for every bar heater wire, by the adjustment to its heater wire width, thus the homogeneous heating of all heater wires to vehicle window can be realized equally, namely the width of every bar heater wire and its length are proportionate, and are less than or equal to preset difference value to make the resistance difference between described many heater wires.
Simultaneously, also can for the region on every bar heater wire residing for each several part, i.e. primary vision area or non-primary vision area, thus make the width of part heater wire is in this primary vision area width that is less, that be in the part in non-primary vision area comparatively large, cause to avoid heater wire and the sight line of chaufeur is hindered.
Embodiment two
In the above-described embodiments, have adjusted its width according to the length of each heater wire, when namely the length of heater wire is larger, its width is also larger, thus makes the resistance of each heater wire equal or roughly equal.
But in heater wire array 1 as shown in Figure 2, when the quantity of heater wire is more, the length difference between each heater wire may be comparatively large, makes the width of longer heater wire possibility excessive, thus cause obstruction to the sight line of chaufeur.
Therefore, in order to avoid the width of heater wire is excessive, the present invention proposes further improvement, be described in detail below in conjunction with Fig. 5.
Fig. 5 shows the structural representation of heater wire array according to another embodiment of the invention.
As shown in Figure 5, in heater wire array 1 according to another embodiment of the invention, to be similar to the rectangle vehicle window shown in Fig. 2, for the structure that many heater wires are arranged in order from the midway location of lower frame to outer rim according to order from short to long, following processing mode can be taked further:
Enclose heater wire in the midway location of lower frame, multiple kink is set.Than in heater wire array 1 as shown in fig. 5, be made up of in first kink 11 and kink 11 ' and enclose heater wire, be made up of in second kink 12 and kink 12 ' and enclose heater wire, be made up of in the 3rd kink 13 and kink 13 ' and enclose heater wire etc., then known by Fig. 5 with Fig. 2 is compared: in the technical scheme shown in Fig. 5, the difference in length of inside enclosing between heater wire and peripheral heater wire is less, contribute to the width reducing peripheral heater wire, avoid the sight line hindering chaufeur.
Wherein, it should be noted that, the quantity of enclosing the kink that heater wire comprises in every bar is not limited to two, but can adjust according to actual needs.
In addition, in the inventive solutions, such as the vehicle window shown in Fig. 2 or Fig. 5, antenna (not shown) can also be set in the position near its outer rim.
Therefore, the present invention by power supply buses being arranged at the lower frame place of vehicle window, thus significantly shortens the black surround width of vehicle window left and right side frame, expands the range of visibility of chaufeur.Meanwhile, by adjusting the width of heater wire, the resistance difference between the heater wire that can reduce different length, thus contribute to realizing the homogeneous heating to whole glass for vehicle window.In addition, can also vision area residing for the different piece on heater wire, regulate the width of the different piece on same heater wire, thus avoid the heater wire part be in primary vision area to hinder the sight line of chaufeur.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
