Description

The present invention relates to a sheet with a conductor provided on a window glass or the like of a moving body, a laminated plate provided with the sheet with the conductor, and a moving body including these.

Conventionally, a laminated plate having a sheet with a conductor has been widely used. The sheet with a conductor has a patterned conductor. A laminated plate having a sheet with a conductor is used, for example, in a defroster (defrosting device) used for a window glass of a moving body such as a vehicle. In such a defroster, a current is passed through a pair of strip-shaped electrodes (called a bus bar) to generate resistance heating in the pattern conductor, and the generated resistance heating is used to form a laminated plate. Heat (for example, Patent Documents 1 and 2). The laminated plate applied to the window glass of the vehicle removes the fogging of the window glass, melts the snow and ice attached to the window glass, or evaporates the water droplets attached to the window glass by the heat generated by the pattern conductor. By doing so, the visibility of the occupants can be secured.

Further, in a moving body such as a vehicle, a photographing device such as a camera may be arranged inside the moving body. The photographing device photographs the outside of the moving body through the window glass of the moving body. Such an imaging device is used, for example, for operating a moving body or assisting the operation of the moving body. As a specific example, the imaging device is used for automatic driving of a moving body. Then, such a photographing device is usually arranged on the side surface of the rear-view mirror or the back side of the rear-view mirror (the side opposite to the side of the mirror surface). By removing the fogging of the window glass in the area facing the photographing device, the photographing by the photographing device can be performed satisfactorily. Therefore, it is desired that the window glass is a laminated plate having a pattern conductor at least in the region facing the photographing device.

In addition, moving objects such as vehicles are generally equipped with a wiper to wipe off water droplets and the like adhering to the window glass, but in cold regions and the like, the blade may freeze at the stop position of the wiper. .. Therefore, depending on the moving body, a device (called a wiper deicer) for preventing the blade from freezing by arranging a heat ray type heater or the like on the window glass at the stop position of the wiper is equipped.

As described above, the laminated plate constituting the window glass of the moving body includes an area for ensuring the occupant's field of view (defroster area 103), an area facing the photographing device (camera area 104), and a wiper deicer. There may be three types of regions of interest (deicer region 105).
However, in the laminated plate constituting the window glass of a moving body such as a conventional vehicle, heat generating devices independent of each other are used in each of the above three types of regions, and the positioning of each is complicated. ..
Further, since the heat generating device used for each area is manufactured separately, the cost is high.

FIG. 8 is a plan view showing an example of a laminated plate constituting a window glass of a conventional moving body (particularly, a window glass of a front window). For example, in the example shown in FIG. 8, in the defroster region 103 of the laminated plate 100, the pattern conductor 113 is arranged between the pair of bus bars 121 composed of the anode 121a and the cathode 121b. Then, a current is passed from the anode 121a of the pair of bus bars 121 to the cathode 121b of the pair of bus bars 121 via the pattern conductor 113 to generate resistance heating in the pattern conductor 113, and the generated resistance heating is used. The defroster region 103 of the laminated plate 100 was heated.

However, as shown in the example shown in FIG. 8, in the conventional laminated plate 100, the defroster region 103, the camera region 104, and the deicer region 105 are in an independent relationship with each other, and the camera region 104 and the deicer region 104 and the deicer region 105 are in an independent relationship with each other. In the region 105, each region was heated by a heat generating device different from the defroster region 103.

FIG. 2 shows the main region 3, the first substrate end side region 4, and the second substrate end side region 5 in the conductor-attached sheet 10 included in the front window 2 of the moving body 1 shown in FIG. It shows the positional relationship, the relationship between each pattern conductor arranged in each region, and the relationship between each bus bar.
Here, the front window 2 of the moving body 1 shown in FIG. 1 usually has a curved surface, but the conductor-attached sheet 10 itself has flexibility, and the planar form also has a curved surface. It is also deformable to have a form, and here, in the sheet 10 with a conductor, the positional relationship between the main region 3, the first substrate end side region 4, and the second substrate end side region 5, and The sheet 10 with a conductor shown in FIG. 2 is exemplified as a rectangular planar form for the reason that it is only necessary to understand the relationship between each pattern conductor and each bus bar arranged in each region.

As shown in FIG. 2, the conductor-attached sheet 10 includes one undivided base material 51.
The base material 51 has a first base material end portion 51a and a second base material end portion 51b located on the opposite side of the first base material end portion 51a in a plan view. Further, the base material 51 has a main region 3 located between the first base material end portion 51a and the second base material end portion 51b, and the first base material end portion 51a with respect to the main base region 3.

It has a second base material end side region pattern conductor 15 arranged in the base material end side region 5.
In other words, in the base material 51, the region where the main area pattern conductor 13 is arranged corresponds to the main area 3, and the region where the first base material end side region pattern conductor 14 is arranged is the first. The region corresponding to the substrate end side region 4 and the region in which the second substrate end side region pattern conductor 15 is arranged corresponds to the second substrate end side region 5.

In the sheet 10 with a conductor, a first pair of bus bars 21 composed of an anode 21a and a cathode 21b are arranged on the side of the first base material end portion 51a of the main region 3.
Then, the first base material end side region pattern conductor 14 is connected to the anode 21a and the cathode 21b of the first pair of bus bars 21.
Therefore, in the sheet 10 with a conductor, a current is passed from the anode 21a of the first pair of bus bars 21 to the cathode 21b via the first base material end side region pattern conductor 14, so that the first base material can be used. The end side region 4 can be heated.

Further, in the sheet 10 with a conductor, a second pair of bus bars 22 composed of an anode 22a and a cathode 22b are arranged on the side of the second base material end portion 51b of the main region 3.
Then, the second base material end side region pattern conductor 15 is connected to the anode 22a and the cathode 22b of the second pair of bus bars 22.
Therefore, in the sheet 10 with a conductor, a current is passed from the anode 22a of the second pair of bus bars 22 to the cathode 22b via the second base material end side region pattern conductor 15, so that the second base material is used. The end side region 5 can be heated.

Further, in the sheet 10 with a conductor, the anode 21a of the first pair of bus bars 21 and the cathode 22b of the second pair of bus bars 22 or the cathode 21b of the first pair of bus bars 21 and the second pair of bus bars. The main region pattern conductor 13 is connected to the anode 22a of 22.
More specifically, in FIG. 2, the main region pattern conductor 13 arranged on the left side from the center of the main region 3 is the anode 21a of the first pair of bus bars 21 and the cathode 22b of the second pair of bus bars 22. It is connected to the. Further, in FIG. 2, the main region pattern conductor 13 arranged on the right side from the center of the main region 3 is connected to the cathode 21b of the first pair of bus bars 21 and the anode 22a of the second pair of bus bars 22. There is.

Therefore, in the sheet 10 with a conductor, with respect to the region on the left side from the center of the main region 3 in FIG. 2, the anode 21a of the first pair of bus bars 21 is arranged on the left side from the center of the main region 3. The region can be heated by passing an electric current through the cathode 22b of the second pair of bus bars 22 via the main region pattern conductor 13.
Similarly, in FIG. 2, for the region on the right side from the center of the main region 3, the main region pattern conductor 13 arranged from the anode 22a of the second pair of bus bars 22 to the right side from the center of the main region 3 is provided. The region can be heated by passing an electric current through the cathode 21b of the first pair of bus bars 21.

Here, as described with reference to FIG. 8, conventionally, heat generating devices independent of each other are used in each of the three types of regions, the defroster region 103, the camera region 104, and the deicer region 105. Each alignment was complicated. Further, in the past, the heat generating devices used in each area were manufactured separately, resulting in high cost.

On the other hand, in the sheet 10 with a conductor shown in FIG. 2, the main region 3, the first substrate end side region 4, and the first substrate 51 are on one surface of one undivided substrate 51. 2 It has three types of regions of the base material end side region 5, and has three types of regions of the main region 3, the first base material end side region 4, and the second base material end side region 5. Each of the arranged pattern conductors can heat each region by utilizing the current from the first pair of bus bars 21 and the second pair of bus bars 22.
Then, with each pattern conductor arranged in three types of regions of the main region 3, the first substrate end side region 4, and the second substrate end side region 5, and the first pair of bus bars 21. The second pair of bus bars 22 can be collectively manufactured on the surface of the base material 51. That is, it is possible to solve the problem of alignment and the problem of cost increase due to separately manufacturing the heat generating device in each of the three types of regions as in the conventional case.
Therefore, in the sheet 10 with a conductor, it is possible to save the trouble of alignment and to reduce the cost.

Further, in the sheet 10 with a conductor shown in FIG. 2, there are three types: a main area pattern conductor 13, a first base material end side region pattern conductor 14, and a second base material end side region pattern conductor 15. The pattern conductor can be powered by two pairs of bus bars, a first pair of bus bars 21 and a second pair of bus bars 22.
Therefore, a pair of each of the three types of pattern conductors, the main area pattern conductor 13, the first base material end side region pattern conductor 14, and the second base material end side region pattern conductor 15. It is also possible to reduce the number of bus bars as compared with the case where the bus bars are provided (that is, three pairs of bus bars are provided). Therefore, the sheet 10 with a conductor can have a simpler structure, and also has an effect of preventing deterioration of the design due to the arrangement of the bus bars.

(Matching board)
FIG. 4 is a cross-sectional view showing an example of the cross-sectional structure of the laminated plate according to the present invention. As shown in FIG. 4, the laminated plate 11 includes a sheet 10 with a conductor, a first transparent substrate 61, a second transparent substrate 62, and a bonding layer 63.
Here, the first transparent substrate 61 is located on the side of the sheet 10 with a conductor opposite to the surface on which the pattern conductor 52 of the base material 51 is arranged. Further, the second transparent substrate 62 is located on the side of the surface on which the pattern conductor 52 of the base material 51 is arranged with respect to the sheet 10 with the conductor. The bonding layer 63 is located between the conductor-attached sheet 10 and the second transparent substrate 62.
In other words, the laminated plate 11 has a structure in which a first transparent substrate 61, a sheet with a conductor 10, a bonding layer 63, and a second transparent substrate 62 are sequentially laminated.

The laminated plate 11 is not limited to the illustrated example, and may be provided with other functional layers expected to exhibit a specific function. Further, one functional layer may exhibit two or more functions. For example, the first transparent substrate 61 and the second transparent substrate 62 of the laminated plate 11, the bonding layer 63, and the sheet 10 with a conductor may be used. Some function may be imparted to at least one of the base materials 51. As an example, the functions that can be imparted to the laminated plate 11 include an antireflection (AR) function, a scratch resistant hard coat (HC) function, an infrared shielding (reflection) function, an ultraviolet shielding (reflection) function, and an antifouling function. Functions, joining functions, etc. can be exemplified.

Since the laminated plate 11 includes the sheet 10 with a conductor, the same effect as that of the sheet 10 with a conductor described above can be obtained. For example, the problem of alignment and the cost due to separately manufacturing the heat generating device in each of the three types of regions, the main region 3, the first substrate end side region 4, and the second substrate end side region 5. The problem of up can be solved.

(Component)
Hereinafter, each component constituting the conductor-attached sheet 10 and the laminated plate 11 will be described.

(Base material)
The base material 51 functions as a base material that supports each pattern conductor and each bus bar of the sheet 10 with a conductor. Further, in the laminated plate 11, the base material 51 functions to bond the sheet 10 with a conductor and the first transparent substrate 61.
The base material 51 is a so-called transparent electrically insulating film that transmits a wavelength in the visible light wavelength band (380 nm to 780 nm).

In the laminated plate 11, the refractive index of the base material 51 is preferably the same as that of the joint layer 63 in order to make it difficult to recognize the boundary between the base material 51 and the bonding layer 63 in contact with the base material 51. As the material of such a base material 51, polyvinyl butyral (PVB), which is the same material as the bonding layer 63, can be exemplified.

The thickness of the base material 51 should be 0.03 mm or more and 0.20 mm or less in consideration of light transmission, appropriate supportability as a base material for supporting a pattern conductor or a bus bar, and the like. Is preferable. By making the base material 51 sufficiently thin, it is possible to make the base material 51 difficult to observe.

In addition, "transparency" means having transparency to the extent that one side of the base material can be seen through the other side through the base material, for example, 30% or more. , More preferably, it means that it has a visible light transmittance of 70% or more. The visible light transmittance is the transmittance at each wavelength when measured using a spectrophotometer (“UV-3100PC” manufactured by Shimadzu Corporation, JIS K 0115 compliant product) within the measurement wavelength range of 380 nm to 780 nm. Specified as the average value of.

(Pattern conductor)
The main region pattern conductor 13, the first base material end side region pattern conductor 14, and the second base material end side region pattern conductor 15 shown in FIG. 2 are all subjected to resistance heating by passing an electric current. Functions as a heating element that is generated. In the sheet 10 with the conductor and the laminated plate 11, the resistance heating generated by the main area pattern conductor 13, the first base material end side region pattern conductor 14, and the second base material end side region pattern conductor 15 is applied. Use to heat each area.

In the example shown in FIG. 2, the main region pattern conductors 13 arranged in the main region 3 are arranged as a plurality of linear patterns between the connected bus bars. However, not limited to the illustrated example, the main region pattern conductor 13 may be arranged in a mesh-like pattern. Further, the main region pattern conductor 13 is not limited to a linear form, but may be a curved form such as a wavy line.

The main region pattern conductor 13 can be formed using an opaque metallic material. On the other hand, the ratio of the region on the base material 51 not covered by the main region pattern conductor 13, that is, the non-coverage ratio is as high as 70% or more and 90% or less. Further, as will be described later, the line width of the main region pattern conductor 13 is about 2 μm or more and 20 μm or less. Therefore, the main region 3 in which the main region pattern conductor 13 is arranged is transparently grasped as a whole so as not to impair the view of the occupant of the moving body 1. That is, the main region pattern conductor 13 is sufficiently invisible to the occupants of the moving body 1.

Further, in the example shown in FIG. 2, the first base material end side region pattern conductor 14 arranged in the first base material end side region 4 and the second base material end side region 5 are arranged. The second substrate end side region pattern conductor 15 is exemplified as a single linear pattern bent between the connected bus bars so as to heat each region evenly. However, not limited to the illustrated example, the first base material end side region pattern conductor 14 and the second base material end side region pattern conductor 15 may be arranged as a plurality of patterns. Further, they may be arranged in a mesh-like pattern. Further, it may be in the form of a curved line such as a wavy line.

In the example shown in FIG. 3, the pattern conductor 52 (same as the main region pattern conductor 13 shown in FIG. 2) has a rectangular cross section as a whole. In order to achieve uniform heating, it is preferable that the plurality of pattern conductors 52 have the same cross-sectional area and are arranged at the same intervals.
The line width (LW) of the pattern conductor 52 is preferably 2 μm or more and 20 μm or less, and the height (LH) is preferably 1 μm or more and 60 μm or less. According to the pattern conductor 52 having such dimensions, the wire is sufficiently thinned, so that the pattern conductor 52 can be effectively invisible.

Further, as shown in FIG. 3, the pattern conductor 52 is a base among the surfaces of the first dark color layer 52b and the conductive layer 52a covering the surface on the substrate 51 side among the surfaces of the conductive layer 52a and the conductive layer 52a. A second dark color layer 52c that covers the surface opposite to the material 51 side and both side surfaces may be included. In particular, the pattern conductor 52 preferably contains at least the first dark color layer 52b. The conductive layer 52a made of a metal material having excellent conductivity exhibits a relatively high reflectance. Then, when the light is reflected by the conductive layer 52a forming the pattern conductor 52, the reflected light is observed, which may obstruct the view of the occupant of the moving body 1.
Further, when the conductive layer 52a is observed from the outside, the design may be deteriorated. Therefore, it is preferable that the second dark color layer 52c covers at least a part of the surface of the conductive layer 52a. This is because it is possible to prevent deterioration of the design when viewed from the outside.
The first dark color layer 52b and the second dark color layer 52c may be a layer having a lower visible light reflectance than the conductive layer 52a, and may be a dark color layer such as black.

The size may be different from the line width LW of the pattern conductor 52 shown. By making the line widths different, for example, the heating in each region where each pattern conductor is arranged can be adjusted.
Here, the first base material end side region pattern conductor 14 and the second base material end side region pattern conductor 15 do not necessarily impair the field of view of the occupant of the moving body 1 even if the line width is increased. It does not become. In particular, the second substrate end side region pattern conductor 15 is arranged in the second substrate end side region 5 which is the stop position of the wiper in the moving body 1, and as illustrated in FIG. 1, this region is usually used. Since it is covered with the colored layer 6, it does not impair the visibility of the occupants of the moving body 1.

The line width is larger than that of the pattern conductor 13, the first base material end side region pattern conductor 14, and the second base material end side region pattern conductor 15). Therefore, heat generation due to resistance heating is unlikely to occur in the anode 21a and the cathode 21b constituting the first pair of bus bars 21 and the anodes 22a and the cathode 22b constituting the second pair of bus bars 22.

On the other hand, the heights of the anode 21a and the cathode 21b constituting the first pair of bus bars 21 and the anodes 22a and the cathode 22b constituting the second pair of bus bars 22 are the heights of the respective pattern conductors (main region pattern conductors). 13.

It may have a dark color layer formed on the surface. The dark color layer makes it difficult to observe the conductive layer exhibiting a relatively high reflectance, and it is possible to secure a good field of view for the occupant and the photographing apparatus. In addition, it is possible to prevent deterioration of the design when viewed from the outside.

Materials for forming such a first pair of bus bars 21 and a second pair of bus bars 22 include, for example, gold, silver, copper, platinum, aluminum, chromium, molybdenum, nickel, titanium, and palladium. , Indium, tungsten and the like, and one or more of alloys comprising one or more of these metals can be exemplified.

This is because it becomes possible to collectively manufacture each pattern conductor and the first pair of bus bars 21 and the second pair of bus bars 22.

In the front window 2, the anodes 21a and cathodes 21b constituting the first pair of bus bars 21 and the anodes 22a and cathodes 22b constituting the second pair of bus bars 22 are colored layer 6 in order to make them difficult to observe.

(Manufacturing method of sheet with conductor)
Next, a method of manufacturing the sheet 10 with a conductor will be described. FIG. 5 is a process diagram showing an example of a method for manufacturing the sheet 10 with a conductor shown in FIG.

<Second embodiment>
(Sheet with conductor)
FIG. 7 is a plan view showing an example of a second embodiment of the sheet with a conductor according to the present invention.
In the conductor-attached sheet 10 illustrated in FIGS. 2 and 3, as an example, the main area pattern conductors 13 arranged in the main area 3 all have the same line width and the same height (that is, the same cross-sectional area). The morphology was illustrated.
On the other hand, in the sheet 10A with a conductor of the second embodiment shown in FIG. 7, the main region 3 is a second group facing the first base material end side region 4 and the first base material end side region 4. It has a central main area 3a located between the material end side area 5 and both side main areas 3b located on both sides of the central main area 3a, and a central main area pattern arranged in the central main area 3a. The cross-sectional area of the conductor 13a is smaller than the cross-sectional area of the bilateral main region pattern conductors 13b arranged in the bilateral main region 3b.

In a form such as the sheet 10A with a conductor exemplified in FIG. 7, in which the first base material end side region 4 pushes against the main region 3 in the direction of the second base material end portion 51b, the first 1 Due to the presence of the base material end side region 4, the length of the main region pattern conductor 13 arranged in the main region 3 differs depending on the position of the arrangement.

Specifically, in the sheet 10A with a conductor illustrated in FIG. 7, it faces the central portion of the main region 3 (more specifically, the first substrate end side region 4 and the first substrate end side region 4). The length of the central main region pattern conductor 13a arranged in the central main region 3a) located between the second base material end side region 5 is other than the central portion of the main region 3 (more specifically, the main region). In No. 3, the length is shorter than the length of the bilateral main region pattern conductors 13b arranged in the bilateral main regions 3b) located on both sides of the central main region 3a.
Assuming that the central main region pattern conductor 13a and the both side main region pattern conductors 13b have the same cross-sectional area, the short pattern conductor (central main region pattern conductor 13a) is a long pattern conductor (both sides main). The electrical resistance is smaller than that of the region pattern conductor 13b), and the heat generated by resistance heating is also smaller.

Therefore, when the area occupied by the end side region 4 of the first substrate in the conductor-attached sheet 10A is large, the calorific value of the central main region pattern conductor 13a arranged in the central main region 3a and the heat generation amount in the both side main regions 3b The difference between the amount of heat generated by the arranged main region pattern conductors 13b on both sides becomes large, and the heating of the main region 3 becomes non-uniform between the central portion (central main region 3a) and the others (main regions 3b on both sides). It may end up.

On the other hand, in the sheet 10A with a conductor, the cross-sectional area of the central main region pattern conductor 13a, which is a short pattern conductor, is made smaller than the cross-sectional area of the bilateral main region pattern conductor 13b, which is a long pattern conductor. ing.
Therefore, in the conductor-attached sheet 10A according to the present embodiment, in addition to the effect of the conductor-attached sheet 10 according to the first embodiment, the area occupied by the first base material end side region 4 is occupied. Even if it is large, the difference between the calorific value of the central main region pattern conductor 13a arranged in the central main region 3a and the calorific value of the bilateral main region pattern conductors 13b arranged in the bilateral main region 3b is small. It also has the effect that the heating of the main region 3 can be adjusted to be more uniform in the central portion (central main region 3a) and the others (both sides main region 3b).

Here, in order to make the cross-sectional area of the central main region pattern conductor 13a smaller than the cross-sectional area of the bilateral main region pattern conductors 13b, the heights of the central main region pattern conductor 13a and the bilateral main region pattern conductors 13b ( It is preferable that the LH) in FIG. 3 is the same and the line width of the central main area pattern conductor 13a is smaller (thinner) than the line width of the bilateral main area pattern conductors 13b (LW in FIG. 3).

This is because if the heights are the same, the central main region pattern conductor 13a and the both side main region pattern conductors 13b can be manufactured at once. More specifically, in the manufacturing method shown in FIG. 5, the line width of the resist pattern 70 in FIG. 5B is set to the line width corresponding to each of the central main region pattern conductor 13a and both side main region pattern conductors 13b. By doing so, the central main region pattern conductor 13a and the both side main region pattern conductors 13b can be manufactured together.
