[0008] The technical problem that the invention aims to solve

[0009] In recent years, with the increasing functionality of driver assistance systems, the number of information acquisition devices installed on vehicle windows (windshields) has been increasing. Consequently, the increased number of information acquisition devices on vehicle windows also necessitates an increase in the area of ​​the brackets used to mount these devices.

[0010] However, because vehicle window glass has a curved shape, the increased area of ​​the bracket results in a restoring force acting on the bracket when it is attached to the vehicle window glass (the force required for restoration: see [reference]). Figure 3 (See the image below) becomes larger. Therefore, after the bracket is attached to the vehicle window glass, there are problems such as the bracket falling off, the position of the fixing parts used to install the information acquisition device shifting, or poor fitting.

[0011] In view of the above problems, the object of the present invention is to provide a bracket and an information acquisition module that can accurately install an information acquisition device on a vehicle window glass.

[0012] means of solving technical problems

[0013] One embodiment of the bracket of the present invention is a resin bracket for fixing an information acquisition device to a vehicle window glass having a curved shape, the bracket having multiple regions and connecting regions disposed between the multiple regions. The connecting regions are mesh-like and flexibly connect the multiple regions.

[0014] One aspect of the present invention provides an information acquisition module comprising: the bracket affixed to a vehicle window glass, a plurality of information acquisition devices respectively installed in the plurality of areas of the bracket, and a cover covering the plurality of information acquisition devices.

[0029] The embodiments of the present invention will now be described with reference to the accompanying drawings. Figure 1 This is a top view of the bracket used to illustrate the implementation method. For example... Figure 1 As shown, the bracket 1 of the embodiment includes multiple regions 10a, 10b and a connecting region 11. The connecting region 11 is a mesh obtained by removing at least a portion of the components, which flexibly connects the multiple regions 10a, 10b. Each of the multiple regions 10a, 10b is provided with a hole 18a, 18b.

[0030] exist Figure 1 In the structural example shown, multiple regions 10a and 10b are arranged along the x-axis direction (left-right direction). Regions 10a and 10b are connected by a connecting region 11. Multiple elongated holes 15 are formed in the connecting region 11. That is, by removing at least a portion of the material constituting the connecting region 11 to form the elongated holes 15, the connecting region 11 can be made into a mesh. In this way, by making the connecting region 11 into a mesh, multiple regions 10a and 10b can be flexibly connected. Specifically, the connecting region 11 is connected by displacing multiple regions 10a and 10b in the x-axis direction (left-right direction), the z-axis direction (a direction different from the x-axis and y-axis directions), and the y-axis direction (up-down direction). In addition, in each figure, the x-axis direction, y-axis direction, and z-axis direction are perpendicular to each other, but they may also be non-perpendicular and inclined.

[0031] Especially Figure 1 In the structural example shown, the plurality of elongated holes 15 formed in the connecting region 11 are elongated holes extending along the y-axis in the length direction. Therefore, the connecting region 11 has a structure that is easily expandable and contractible in the x-axis direction. Thus, the connecting region 11 can connect regions 10a and 10b in a manner that is easily expandable and contractible in the x-axis direction.

[0032] The bracket 1 in this embodiment is made of resin material. The resin material can be a mixture of polybutylene terephthalate, polycarbonate, and acrylonitrile butadiene styrene. Alternatively, glass fiber can be mixed into these resins.

[0033] For example, the bracket 1 can be integrally formed using injection molding. That is, the bracket 1 can be integrally formed by injecting molten resin material into a mold that corresponds to the shape of the plurality of regions 10a, 10b and the connecting region 11 and then cooling it.

[0034] In this embodiment, the bracket 1 is used to fix the information acquisition device to a vehicle window glass with a curved shape. The vehicle window glass can be a front window glass installed at the front of the vehicle, a rear window glass installed at the rear of the vehicle, or a fixed side window glass installed on the side of the vehicle. Figure 2 This is a cross-sectional view used to illustrate the information acquisition module 20 of this embodiment. For example... Figure 2 As shown, bracket 1 is attached to the inside of vehicle window glass 21. For example, bracket 1 is attached to vehicle window glass 21 with adhesive. An information acquisition device 22 is installed on bracket 1. For example, the information acquisition device 22 can be fixed to bracket 1 by fitting the information acquisition device 22 into a fixing component provided on bracket 1, or by fixing it with screws. In addition, a cover 23 covering the information acquisition device 22 is also fixed to bracket 1. For example, the cover 23 can be fixed to bracket 1 by fitting the cover 23 into a fixing component provided on bracket 1, or by fixing it with screws.

[0035] In this embodiment, it is preferable to... Figure 1 Different information acquisition devices 22 are installed in the multiple regions 10a and 10b shown, but identical information acquisition devices 22 can also be installed in the multiple regions 10a and 10b. Each of the multiple regions 10a and 10b has a fixing component for securing the respective information acquisition device 22. Thus, by installing different information acquisition devices 22 in the multiple regions 10a and 10b, and allowing the connecting region 11 to flexibly bend or extend, even if the relative positions of the multiple regions 10a and 10b are offset, the reduction in the installation accuracy of the information acquisition devices 22 can be suppressed.

[0036] The information acquisition device 22 can be at least one of, for example, a camera, millimeter-wave radar, infrared sensor, communication equipment, rain sensor, and temperature and humidity sensor. However, in this embodiment, the information acquisition device 22 is not limited to these; it can be any device that can be mounted on a vehicle window.

[0037] In this embodiment, holes 18a and 18b are formed in multiple regions 10a and 10b. For example, by aligning the lens of a camera, the transceiver of a millimeter-wave radar, and the light-receiving part of an infrared sensor with the positions of holes 18a and 18b, information outside the vehicle can be accurately acquired. Alternatively, in this embodiment, a hole different from the holes 18a and 18b used for the information acquisition device 22 can be formed in one of the multiple regions 10a and 10b, and the rearview mirror base for the rearview mirror can be directly mounted on the vehicle window glass via the hole. Furthermore, the multiple regions may also include areas where the information acquisition device 22 is not installed.

[0038] As mentioned above, in recent years, with the increasing functionality of driver assistance systems, the number of information acquisition devices installed on vehicle windows has been increasing. Consequently, the increased number of information acquisition devices on vehicle windows also leads to an increase in the area of ​​the brackets used to install these devices.

[0039] Vehicle window glass has a curved shape. On the other hand, the surface where the bracket is bonded to the vehicle window glass is not curved, but rather roughly flat. Therefore, if the area of ​​the bracket increases, the restoring force (the force that is to be restored) acting on the bracket becomes larger in order to bond the bracket along the curved surface of the vehicle window glass.

[0040] Specifically, such as Figure 3 As shown in the above figure, the vehicle window glass 121 has a curved shape. Therefore, when the bracket 101, whose adhesive surface to the vehicle window glass is approximately flat, is attached along the curved surface of the vehicle window glass 121, as shown in the figure above, the following applies: Figure 3 As shown in the figure below, a restoring force (a force on the positive side of the z-axis) is applied to return the bracket 101 to its original shape. The magnitude of this restoring force increases with the area of ​​the bracket 101. Thus, if the restoring force acting on the bracket 101 increases, problems may occur such as the bracket 101 detaching, the position of the fixing parts used to install the information acquisition device shifting, or poor fitting after the bracket 101 is attached to the vehicle window glass 121.

[0041] In contrast, in this embodiment of the invention, such as Figure 4 As shown in the figure above, a connecting region 11 is provided between multiple regions 10a and 10b of the bracket 1. The connecting region 11 is a mesh and flexibly connects the multiple regions 10a and 10b. Therefore, as... Figure 4 As shown in the figure below, when the bracket 1 is attached to the curved shape of the vehicle window glass 21, each region 10a, 10b can conform to the curvature of the surface of the vehicle window glass 21. Therefore, when the bracket 1 is attached to the vehicle window glass 21, the restoring force acting on the bracket 1 can be reduced. By adopting such a structure, it is possible to prevent the bracket 1 from falling off after it is attached to the vehicle window glass 21, the positional displacement of the fixing parts for mounting the information acquisition device, or poor fitting. Therefore, a bracket and an information acquisition module that can be accurately mounted on the vehicle window glass can be provided.

[0042] In this embodiment, multiple regions 10a and 10b can be arranged in the left-right direction (x-axis direction) of the vehicle window glass 21. In this case, the connecting region 11 connects the multiple regions 10a and 10b in a manner that follows the curvature of the left-right direction of the vehicle window glass surface when the bracket 1 is attached to the vehicle window glass 21 which has a curved shape.

[0043] Alternatively, in this embodiment, multiple regions can also be configured to be arranged in the vertical direction (y-axis direction) of the vehicle window glass 21 (see reference). Figure 10 Regions 10b and 10d). In this case, when the bracket is attached to the vehicle window glass 21 with a curved shape, multiple regions are connected in a manner that follows the curvature in the vertical direction of the surface of the vehicle window glass 21.

[0044] For example, the radius of curvature of the vehicle window glass 21 in the left-right direction (x-axis direction) is 2500mm to 11000mm, and the radius of curvature in the up-down direction (y-axis direction) is 2000mm to 7000mm. That is, the vehicle window glass 21 has a multi-curved shape that is curved in both the left-right direction (x-axis direction) and the up-down direction (y-axis direction). In addition, the radius of curvature in the left-right direction (x-axis direction) and the radius of curvature in the up-down direction (y-axis direction) can be the same or different. The bracket 1 of this embodiment can be applied to vehicle window glass with such radii of curvature. For example, the length of a region of the bracket 1 in the left-right direction (x-axis direction) is preferably 80mm to 100mm, and the length in the up-down direction (y-axis direction) is preferably 60mm to 80mm.

[0045] in addition, Figure 1 The structure shown illustrates an example of a structure in which the connecting region 11 extends along the y-axis direction, but in this embodiment, the connecting region 11 may also be inclined relative to the y-axis direction.

[0046] Alternatively, in this embodiment, the multiple regions 10a and 10b can also be arranged along an inclined direction (a direction inclined relative to the x-axis and y-axis). In this case, the direction in which the connecting region 11 extends can also be an inclined direction (a direction inclined relative to the x-axis and y-axis).

[0047] Furthermore, in this embodiment, the number of multiple regions and the number of connected regions can be arbitrarily determined. For example, in this embodiment, the number of multiple regions can be determined based on the number of information acquisition devices 22 installed on the bracket 1.

[0048] Next, the case of attaching the bracket of this embodiment to a vehicle window glass will be described. Figure 5 This is a top view illustrating the case where the bracket of this embodiment is attached to a vehicle window glass. Figure 6 yes Figure 5 The cross-sectional view at the cut line VI-VI is a cross-sectional view showing the state of the bracket with adhesive applied. Figure 7 This is a cross-sectional view used to illustrate the state of the bracket being attached to the window glass of a vehicle. Figure 8 yes Figure 5A cross-sectional view at the cut line VIII-VIII. Figure 9 yes Figure 8 An enlarged sectional view of the dashed section. Additionally, Figures 5-9 The diagram shows a bracket 1 with three regions 10a to 10c and two connecting regions 11 and 12. Specifically, it shows a structure where connecting region 11 flexibly connects regions 10a and 10b, and connecting region 12 flexibly connects regions 10b and 10c. Additionally, as... Figure 5 As shown, holes 18a to 18c are provided in each region 10a to 10c.

[0049] The vehicle window glass 21 can be a single piece of glass or laminated glass. When the vehicle window glass is a windshield, it is preferably laminated glass. When the vehicle window glass is laminated glass, it is formed by bonding an inner glass panel located on the inside of the vehicle and an outer glass panel located on the outside of the vehicle together with an interlayer film when the vehicle is installed on the vehicle.

[0050] Vehicle window glass can be either inorganic or organic glass. As inorganic glass, there are no particular limitations on the types used, such as soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass. Among these, soda-lime glass is particularly preferred from the viewpoint of manufacturing cost and formability. There are no particular limitations on the forming method of vehicle window glass. For example, in the case of inorganic glass, glass sheets formed by processes such as float glass are preferred.

[0051] When the vehicle window glass is made of inorganic glass, it can be either untempered or tempered glass. Untempered glass is glass formed from molten glass into a sheet and then annealed. Tempered glass is glass in which a compressive stress layer is formed on the surface of untempered glass; it can be either air-cooled tempered glass or chemically tempered glass. Additionally, when the vehicle window glass is laminated glass, both the inner and outer glass panels can be untempered glass. When the vehicle window glass is a single piece of glass, it can be tempered glass.

[0052] When the tempered glass is physically tempered (e.g., air-cooled tempered glass), the glass surface can be strengthened by generating a compressive stress layer on the glass surface due to the temperature difference between the glass surface and the interior of the glass, through operations other than annealing, such as rapidly cooling the glass sheet, which is uniformly heated during bending, from a temperature near its softening point. When the tempered glass is chemically tempered, the glass surface can be strengthened by generating compressive stress on the glass surface after bending using methods such as ion exchange. Furthermore, glass that absorbs ultraviolet or infrared radiation can also be used for vehicle windows. Vehicle windows are preferably transparent, but glass sheets tinted to a degree that does not impair transparency are also acceptable.

[0053] Vehicle window glass can be a curved shape that protrudes from the outer side of the vehicle when installed on the vehicle. When the vehicle window glass is laminated glass, both the inner and outer glass panels can be curved shapes that protrude from the outer side of the vehicle. As mentioned above, the radius of curvature of the vehicle window glass in the left-right direction (x-axis direction) is 2500mm to 11000mm, and the radius of curvature in the up-down direction (y-axis direction) is 2000mm to 7000mm. In the bending and forming of vehicle window glass, gravity forming, pressure forming, or roll forming can be used.

[0054] When the vehicle window glass is laminated glass, the thickness of the inner glass panel can be the same as or different from the thickness of the outer glass panel. The thickness of the inner glass panel is preferably 0.3mm to 2.3mm. A thickness of 0.3mm or more ensures good handling, while a thickness of 2.3mm or less prevents excessive weight. The thickness of the outer glass panel is preferably 1.0mm to 3.0mm. A thickness of 1.0mm or more provides sufficient strength for resistance to flying stones, while a thickness of 3.0mm or less prevents excessive weight from the perspective of fuel economy. If the thickness of both the outer and inner glass panels is 1.8mm or less, both lightweight and sound insulation properties of the laminated glass can be balanced, making this a preferred option. Furthermore, when the thickness of the inner glass panel is 1.0mm or less, it can be chemically strengthened glass. When the inner glass panel of the vehicle is chemically strengthened glass, the compressive stress value of the glass surface is preferably 300 MPa or more, and the depth of the compressive stress layer is preferably 2 μm or more.

[0055] When vehicle windows are laminated glass, the interlayer can be made of known thermoplastic resin films such as polyvinyl butyral (PVB) or ethylene vinyl acetate copolymer (EVA). The interlayer can be transparent or colored. Furthermore, the interlayer can consist of two or more layers.

[0056] In addition, when the window glass for vehicles is made of plexiglass, transparent resins such as polycarbonate or acrylic resin (e.g., polymethyl methacrylate) can be used as materials for plexiglass.

[0057] The vehicle window glass has a shielding layer at its periphery. When the vehicle window glass is laminated glass, the shielding layer may be present at at least one of the periphery of the inner surface of the inner glass panel and the periphery of the inner surface of the outer glass panel. The shielding layer is formed, for example, by coating a ceramic pigment containing a molten glass frit with black pigment and then firing it. The shielding layer prevents the adhesive applied to the vehicle window glass from deteriorating due to ultraviolet light, etc. Therefore, the bracket 1 in this embodiment is adhered to the shielding layer. Furthermore, from the viewpoint of improving weather resistance, improving hydrophilicity or water repellency, various suitable films can be formed on the main surface of the vehicle window glass.

[0058] like Figure 5 , Figure 7 As shown, when attaching the bracket 1 of this embodiment to the vehicle window glass 21, adhesive 51 is applied to the bracket 1 and then it is attached to the vehicle window glass 21. At this time, as Figure 5 , Figure 8 As shown, by using double-sided tapes 17a to 17d to temporarily fix the bracket 1 to the vehicle window glass 21, it is possible to prevent the adhesive 51 from peeling off or shifting from the vehicle window glass 21 during the drying process.

[0059] like Figure 5 As shown, the multiple regions 10a to 10c connected by connecting regions 11 and 12 are preferably fixed to the vehicle window glass 21 by adhesive 51. When the multiple regions 10a to 10c are fixed to the vehicle window glass 21 by adhesive 51, the multiple regions 10a to 10c will not change relative to each other. That is, after the bracket 1 is pasted to the vehicle window glass 21 and the adhesive 51 dries, the pasting position of regions 10a to 10c will not change in either the in-plane direction of the vehicle window glass 21 or the direction away from the surface of the vehicle window glass 21. In this embodiment, because the connecting region 11 can flexibly bend or stretch, when the bracket 1 is attached to the vehicle window glass 21, it can follow the bending surface of the vehicle window glass 21. Even if the relative positions of the multiple regions 10a to 10c are offset, the position can be finely adjusted. After the adhesive 51 applied to regions 10a to 10c dries and the bracket 1 is fixed to the vehicle window glass 21, regions 10a to 10c will not change from the attached position. Furthermore, even if the adhesive strength of any of the adhesives 51 applied to regions 10a to 10c decreases due to deterioration, since regions 10a to 10c are connected by connecting regions 11 and 12, it is possible to suppress the change of the region with reduced adhesive strength in either the in-plane direction of the vehicle window glass 21 or the direction away from the surface of the vehicle window glass 21.

[0060] In addition, such as Figure 5As shown, adhesive 51 is applied to bracket 1 (in... Figure 5 When the bracket 1 (shown as dashed lines) is adhered to the vehicle window glass 21, adhesive can be applied not only to regions 10a-10c of the bracket 1, but also to at least a portion of the connecting regions 11 and 12. That is, an adhesive layer can be formed not only in regions 10a-10c of the bracket 1, but also to at least a portion of the connecting regions 11 and 12. Furthermore, the adhesive layer in regions 10a-10c of the bracket 1 and the adhesive layer in at least a portion of the connecting regions 11 and 12 can be formed continuously. If adhesive 51 is applied to the bracket 1 and adhered to the vehicle window glass 21, and an adhesive layer is formed in at least a portion of the connecting regions 11 and 12, the bonding area between the bracket 1 and the vehicle window glass 21 increases, thus improving the bonding strength of the bracket 1, which is preferable.

[0061] like Figure 6 As shown, when applying adhesive 51 to the bracket 1, the adhesive 51 is applied to the bracket 1 mounted on the adhesive application fixture 55. At this time, the adhesive 51 applied to the elongated hole 15 in the connection region 11 can be prevented from falling to the underside of the elongated hole 15 due to the adhesiveness of the adhesive 51. Therefore, adhesive 51 can also be applied to the connection region 11 where the elongated hole 15 is formed.

[0062] Furthermore, such as Figure 7 As shown, when the bracket 1 is attached to the vehicle window glass 21, the adhesive 51 also enters the elongated holes 15 in the connecting areas 11 and 12 (the adhesive entering the elongated holes 15 is indicated by reference numeral 53 in the attached drawing), so it can be seen that the adhesive is effectively applied. Furthermore, in the process of applying adhesive 51 to the bracket 1, adhesive 51 can be continuously applied to areas 10a-10c and connecting areas 11 and 12 (see reference 1). Figure 5 Therefore, this is preferable. Furthermore, if an adhesive layer is also formed in the connecting regions 11 and 12 of the bracket 1, the adhesive may enter the elongated holes 15 in the connecting regions 11 and 12, or the elongated holes 15 may be completely filled with adhesive (see [reference]). Figure 7 Alternatively, an adhesive layer can be formed by applying adhesive 51 to all the elongated holes 15 in the connecting regions 11, 12, or an adhesive layer can be formed only in a portion of them.

[0063] In addition, in this embodiment, such as Figure 8 As shown, by temporarily fixing the bracket 1 to the vehicle window glass 21 using double-sided tape 17a-17d, the bottom surface of the bracket 1 (region 10b) can be securely fixed to the surface of the vehicle window glass 21, which has a curved shape. That is, as... Figure 9As shown, by making the thickness of the positive side of the double-sided tape 17c in the x-axis direction t1 and the thickness of the negative side in the x-axis direction t2, the distance difference between the surface of the vehicle window glass 21 and the bottom surface of the region 10b can be eliminated using the double-sided tape 17c.

[0064] Furthermore, the above description explained the case where double-sided tape 17a to 17d was used to temporarily fix the bracket 1 to the vehicle window glass 21 when the bracket 1 was attached to the vehicle window glass 21 with adhesive 51. However, in this embodiment, it is not necessary to use double-sided tape 17a to 17d for temporary fixation, and the bracket 1 can be directly attached to the vehicle window glass 21 with adhesive 51 without using double-sided tape 17a to 17d.

[0065] Next, using Figure 10 The top view shown illustrates a specific structural example of the bracket in this embodiment. Figure 10 The bracket 2 shown has regions 10a to 10d. Regions 10a to 10c are arranged along the x-axis. This direction corresponds to the left-right direction of the vehicle window. Additionally, regions 10b and 10d are arranged along the y-axis. This direction corresponds to the up-down direction of the vehicle window.

[0066] A connecting region 11 is provided between region 10a and region 10b. Connecting region 11 flexibly connects region 10a and region 10b. A connecting region 12 is provided between region 10b and region 10c. Connecting region 12 flexibly connects region 10b and region 10c. A connecting region 13 is provided between region 10b and region 10d. Connecting region 13 flexibly connects region 10b and region 10d.

[0067] Holes 31a to 31d are provided in each of the regions 10a to 10d. Holes 31a to 31d are portions obtained by removing the resin material constituting the bracket 2. For example, by aligning the lens of the camera, the transceiver of the millimeter-wave radar, the light-receiving part of the infrared sensor, etc., with the positions of holes 31a to 31d, information outside the vehicle can be accurately obtained.

[0068] Furthermore, fixing components 32a to 32d are provided in each of the zones 10a to 10d. When installing each information acquisition device in each of the zones 10a to 10d, the fixing components 32a to 32d are used to secure each information acquisition device. Additionally, Figure 10 The example shown is that the fixing parts 32a to 32d are protruding, but the shape of the fixing parts 32a to 32d is not limited to this.

[0069] Furthermore, the bracket 2 is provided with fixing members 35a to 35f. For example, six fixing members 35a to 35f are formed on the bracket 2, which can be used to fix the cover covering the entire bracket 2. That is, by using the fixing members 35a to 35f, the cover covering the information acquisition device installed in each area 10a to 10d can be fixed. In addition, the cover covering each information acquisition device can also be provided in each of each area 10a to 10d.

[0070] Furthermore, the present invention is not limited to the above-described embodiments, and appropriate modifications can be made without departing from the spirit of the invention. For example, in Figure 1 In the structural examples shown, a plurality of elongated holes 15 are formed in the connecting region 11, and the connecting region 11 is formed into a mesh. However, in this embodiment, it is also possible, for example, like Figure 11 As shown, the connecting region 11 is made into a mesh by forming multiple polygonal holes 41 in the connecting region 11. Figure 11 In the diagram, hole 41 is rhomboid in shape, but the hole can also be hexagonal or octagonal. Alternatively, it can be, for example, like... Figure 12 As shown, the connecting region 11 is made into a mesh by forming a plurality of circular holes 42 in the connecting region 11. Furthermore, the shape of the holes 42 can also be elliptical. In this embodiment, as long as the connecting region can be made into a mesh, the shape of the holes provided in the connecting region can also be other than these shapes.

[0071] In bracket 1, the elongated hole 15 in connecting region 11 is preferably a through hole. Furthermore, the thickness of the portion of connecting region 11 other than the elongated hole 15, i.e., the portion of resin material, is preferably the same as the thickness of at least one of the regions 10a, 10b adjacent to connecting region 11. If the thickness of the portion of connecting region 11 other than the elongated hole 15, i.e., the portion of resin material, is the same as the thickness of at least one of the regions 10a, 10b adjacent to connecting region 11, the strength of bracket 1 in connecting region 11 is increased, which is therefore preferable.

[0072] Additionally, the connection region 11 is preferred. Figure 1 Multiple rows of elongated holes 15 are formed as shown. If multiple rows of elongated holes 15 are formed, the strength of the bracket 1 in the connecting region 11 is increased, while the flexibility and extensibility of the connecting region 11 are also increased, which is therefore preferable. Similarly, it is preferable to form... Figure 11 , Figure 12 Multiple rows of holes 41 and 42 are formed as shown. Alternatively, they can be formed as shown... Figure 10 As shown, the number of elongated holes in connecting regions 11 and 12 varies depending on the column. It can also be like... Figure 10As shown, in the connecting regions 11 and 12, the number of elongated holes on the outer periphery of the bracket 2 is relatively large, while the number of elongated holes gradually decreases as it moves toward the center of the connecting regions 11 and 12.

[0073] in addition, Figure 10 The preferred images shown are the connecting regions 11, 12, and 13. Figure 1 The connecting areas are formed continuously from the top to the bottom and / or from the right to the left of the bracket 2, as shown. If the connecting areas are formed continuously from the top to the bottom and / or from the right to the left of the bracket 2, the flexibility and extensibility of the connecting areas 11, 12, and 13 are improved, which is therefore preferred.

[0074] exist Figure 10 In the connecting regions 11, 12, and 13 shown, the ratio of the total area of ​​the elongated holes 15 to the area of ​​each connecting region is preferably 20% to 50%. If the ratio of the total area of ​​the elongated holes 15 to the area of ​​the connecting region is 20% or more, the connecting region can flexibly bend or expand, which is therefore preferable. If the ratio of the total area of ​​the elongated holes 15 to the area of ​​the connecting region is 50% or less, the strength of the bracket 1 in the connecting regions 11, 12, and 13 is increased, which is also preferable.

[0075] Furthermore, the bracket of this embodiment can also be used to fix components other than the information acquisition device to the vehicle window glass. For example, the bracket of this embodiment can also be used when fixing resin components (such as clamps) to the vehicle window glass. That is, the bracket of this embodiment can also be used as a seat for resin components (clamps, etc.). In this way, by using the bracket of this embodiment as a seat for resin components, the adhesion when fixing resin components to the vehicle window glass can be improved.

[0076] The present invention has been described above based on the above embodiments, but the present invention is not limited to the above embodiments, and of course includes various modifications, alterations and combinations that can be made by those skilled in the art within the scope of the claims of this application.
