DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. For ease of understanding, the scale of each part in the drawings may differ from the actual scale. In directions such as parallel, right angle, orthogonal, horizontal, vertical, up / down, left / right, etc., deviations are permitted to the extent that do not impair the effects of the embodiment. The shape of the corners is not limited to right angles, and may be rounded in an arch shape. Parallel, right angle, orthogonal, horizontal, and vertical may include approximately parallel, approximately right angle, approximately orthogonal, approximately horizontal, and approximately vertical. In this specification, "approximately" refers to a state in which something is considered to have the same shape and the same dimensions when viewed by a human.

[0012] <Embodiment 1> FIG. 1 is a diagram showing an example of a vehicle window glass 400 to which a mounting member 100 according to the first embodiment is fixed. The vehicle window glass 400 is a glass plate attached to a window of an automobile. The vehicle window glass 400 is, for example, a windshield. The vehicle window glass 400 may be a rear glass, a side glass, a roof glass, or the like. Examples of glass constituting the vehicle window glass 400 include soda lime glass, aluminosilicate glass, borate glass, lithium aluminosilicate glass, and borosilicate glass. The vehicle window glass 400 may be a single glass plate or a laminated glass.

[0013] FIG. 1 is a schematic diagram of a vehicle window glass 400 viewed from the left side of a vehicle. In this specification, front, rear, left, right, and up and down correspond to front, rear, left, right, and up and down of a vehicle equipped with the vehicle window glass 400. As shown in FIG. 1, an in-vehicle member 500 is attached to the surface of the vehicle window glass 400 on the vehicle inner side. The in-vehicle member 500 is, for example, a rearview mirror. The rearview mirror may be a high-performance digital inner mirror. The digital inner mirror is a rearview mirror that can display camera images around and behind the vehicle. The in-vehicle member 500 may be a sensor or a camera. The in-vehicle member 500 is attached to the vehicle window glass 400 by a mounting member 100. The method of mounting the in-vehicle member 500 is not particularly limited. The in-vehicle member 500 may be attached by being fitted into the mounting member 100, for example. The in-vehicle member 500 may also be attached by being screwed to the mounting member 100.

[0014] Next, the configuration of the mounting member 100 will be described with reference to Fig. 2 and Fig. 3. Fig. 2 is a three-sided view of the mounting member 100 according to the first embodiment. The upper left view of Fig. 2 is a front view of the mounting member 100. The upper right view of Fig. 2 is a side view of the mounting member 100. The lower left view of Fig. 2 is a bottom view of the mounting member 100. As shown in Fig. 2, the mounting member 100 includes a mounting base 200 and an adhesive member 300. Fig. 3 is a perspective view of the mounting base 200 according to the first embodiment.

[0015] Hereinafter, the surface of the mounting base 200 that contacts the adhesive member 300 is referred to as the adhesive surface 220. Also, the surface that is approximately parallel to the adhesive surface 220 and faces the in-vehicle member 500 is referred to as the mounting surface 210. As shown in FIG. 2, the mounting base 200 is, for example, approximately trapezoidal in front view, with the length of the upper side being shorter than the length of the lower side. Also, the mounting base 200 is, for example, approximately trapezoidal in bottom view, with the length of the side of the mounting surface 210 being longer than the length of the side of the adhesive surface 220. Therefore, the area of ​​the mounting surface 210 is larger than the area of ​​the adhesive surface 220.

[0016] The mounting base 200 is a plate-shaped resin member. The method of molding the mounting base 200 is not particularly limited, and may be, for example, injection molding. Examples of resins constituting the mounting base 200 include polyesters such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), polyolefins such as polyethylene (PE) and polypropylene (PP), polycarbonate (PC), polyamides (PA) such as nylon 6 and nylon 6,6, high heat resistant polyamides (PA6T / PA6I), polyimides (PI), polyetherimides (PEI), acrylonitrile-butadiene-styrene (ABS), polyacetal (POM), polyvinyl chloride (PVC), polyphenylene sulfide (PPS), and the like. Among these resins, polybutylene terephthalate (PBT), high heat resistant polyamides (PA6T / PA6I), and polyphenylene sulfide (PPS) are particularly preferred from the viewpoint of excellent strength.

[0017] The mounting base 200 may be made of a resin reinforced with a filler such as reinforcing fibers or inorganic particles. Examples of reinforcing fibers include glass fibers and carbon fibers. Examples of fiber-reinforced resins include polyetherimide and high heat-resistant polyamide reinforced with glass fibers. When the resin contains reinforcing fibers, the fibers may be contained in an amount of 5% by mass to 70% by mass, and preferably 30% by mass to 50% by mass, based on the total amount of the resin.

[0018] The adhesive member 300 is a member for fixing the mounting base 200 to the vehicle window glass 400. The adhesive member 300 is provided between the mounting base 200 and the vehicle window glass 400. The adhesive member 300 is formed, for example, by curing an adhesive. The adhesive is not particularly limited as long as it is an adhesive used for bonding a window glass and a resin part. Examples of the adhesive include epoxy-based, urethane-based, silicone-based, modified silicone-based, melamine-based, phenol-based, and acrylic-based adhesives. The adhesive may be a one-component type or a two-component type. Specific examples of the adhesive include modified silicone / epoxy adhesives, two-component urethane adhesives, one-component heat-curing urethane adhesives, and second-generation acrylic adhesives (SGA).

[0019] The adhesive member 300 has a Shore A hardness measured in accordance with JIS K6253 of preferably 75 or more, more preferably 78 or more. That is, the adhesive constituting the adhesive member 300 has a Shore A hardness after curing of preferably 75 or more, more preferably 78 or more.

[0020] The adhesive surface 220 of the mounting base 200 is provided with a texture. The texture has a depth of 2 μm to 100 μm. The texture may have a shape such as a matte pattern, a leather pattern, a wood grain pattern, or a block pattern.

[0021] The method of providing the texture on the adhesive surface 220 is not particularly limited. For example, when the mounting base 200 is injection molded, the injection molding may be performed using a molding die in which the area corresponding to the adhesive surface 220 has been textured in advance, and the texture may be provided on the adhesive surface 220. Examples of the texture processing include etching and blasting. Also, the adhesive surface 220 of the formed mounting base 200 may be blasted to provide the texture on the adhesive surface 220. Examples of the blasting process include sand blasting, blower blasting, and shot blasting.

[0022] When the mounting base 200 is fixed to the vehicle window glass 400, for example, the mounting base 200 with adhesive applied to the bonding surface 220 is attached to a predetermined position of the vehicle window glass 400, and the adhesive is hardened. At this time, the adhesive penetrates into the texture provided on the bonding surface 220. In other words, the bonding surface 220 has a larger bonding area than a surface not provided with the texture. Therefore, the mounting base 200 is firmly bonded to the vehicle window glass 400 compared to a mounting base not provided with the texture on the bonding surface. If the depth of the texture is 2 μm or more, the texture processing is easy and the bonding area increases, so that the mounting base 200 is more firmly bonded to the vehicle window glass 400. Also, if the depth of the texture is 100 μm or less, the adhesive is easily blended into the texture.

[0023] The magnitude of the force required to peel off the mounting base 200 fixed to the vehicle window glass 400 from the vehicle window glass 400, i.e., the breaking strength, is preferably 400 N or more, more preferably 500 N or more, further preferably 750 N or more, and particularly preferably 1000 N or more. If the breaking strength is 400 N or more, it is possible to prevent the mounting base 200 from falling off the vehicle window glass 400 together with the in-vehicle member 500 while the vehicle is in use. The breaking strength of the mounting member 100 is measured using a breaking strength measuring device 10 described in the examples described later.

[0024] Furthermore, the change in position of the mounting base 200, i.e., the amount of displacement, when a force is applied in a direction twisting the mounting base 200 fixed to the vehicle window glass 400 relative to the vehicle window glass 400, is preferably 1.2 mm or less, more preferably 1.1 mm or less, and even more preferably 1.0 mm or less. If the amount of displacement is 1.2 mm or less, even if a part of the body (e.g., the head) comes into contact with the side surface of the in-vehicle member 500 while using the vehicle, the mounting base 200 can be prevented from shifting in position relative to the vehicle window glass 400 and from falling off. The amount of displacement of the mounting member 100 is measured using a displacement amount measuring device 11 described in the examples described later.

[0025] The mounting base 200 according to the first embodiment is made of resin, and therefore is lighter than a metal base, has low production costs, and has a high degree of freedom in shape. In addition, the mounting member 100 according to the first embodiment is formed by bonding the mounting base 200 to the vehicle window glass 400 using an adhesive, and therefore can absorb the difference in curvature between the mounting base 200 and the vehicle window glass 400.

[0026] <Embodiment 2> In the second embodiment, at least one groove is provided on the adhesive surface of the mounting base. In the second embodiment, the materials constituting each member are the same as those in the first embodiment, so the description will be omitted. FIG. 4 is a perspective view of a mounting base 800 according to the second embodiment. FIG. 5 is a three-sided view of a mounting member 700 according to the second embodiment. As shown in FIG. 5, the mounting member 700 includes a mounting base 800 and an adhesive member 900.

[0027] The mounting base 800 has a groove 830 on the adhesive surface 820. The groove 830 is a groove that extends linearly from one edge to the other edge of the adhesive surface 820 of the mounting base 800. Specifically, the groove 830 is a groove that extends linearly from the end on the lower surface side of the mounting base 800 to the end on the upper surface side. As shown in FIG. 5, both side walls constituting the groove 830 may be provided so as to approach each other from the mounting surface 810 side toward the adhesive surface 820 side. In other words, both side walls constituting the groove 830 may be provided so as to approach each other from the bottom of the groove 830 toward the end of the groove 830 on the vehicle window glass side.

[0028] 5, the adhesive member 900 is formed so as to enter the groove portion 830. Therefore, the adhesive member 900 can more firmly adhere the mounting base 800 to the vehicle window glass 400 due to an anchor effect, compared to a case where the groove portion 830 is not formed.

[0029] 4 and 5, the case where one groove is provided on the adhesive surface has been described. However, two or more grooves may be provided on the adhesive surface.

[0030] FIG. 6 is a diagram for explaining an example in which two grooves are provided on the adhesive surface. FIG. 6 is a bottom view of a modified example of the mounting member according to the second embodiment. As shown in FIG. 6, the mounting member 1100 includes a mounting base 1200 and an adhesive member 1300. The mounting base 1200 has two grooves 1230, 1231 provided on the adhesive surface 1220. The two grooves 1230, 1231 may be provided parallel to each other from the end of the lower surface side of the mounting base 1200 to the end of the upper surface side. The adhesive member 1300 is formed so as to enter the two grooves 1230, 1231. In the example shown in FIG. 6, the adhesive member 1300 can more firmly adhere the mounting base 1200 to the vehicle window glass 400 by the anchor effect.

[0031] 4 to 6, both side walls of the groove are shaped to approach each other from the bottom of the groove toward the end of the groove on the side of the vehicle window glass 400. However, the shape of the side walls of the groove is not limited to the above.

[0032] Fig. 7 is a bottom view of a modified mounting member according to embodiment 2. The mounting member 1500 shown in Fig. 7 includes a mounting base 1600 and an adhesive member 1700. The mounting base 1600 includes a groove 1630 on an adhesive surface 1620. The cross section of the groove 1630 when cut in a direction perpendicular to the direction in which the groove 1630 extends is semicircular. The adhesive member 1700 is formed to fit into the groove 1630.

[0033] Fig. 8 is a bottom view of a modified mounting member according to embodiment 2. The mounting member 1900 shown in Fig. 8 includes a mounting base 2000 and an adhesive member 2100. The mounting base 2000 includes a groove 2030 on an adhesive surface 2020. The cross section of the groove 2030 when cut in a direction perpendicular to the extension direction of the groove 2030 is rectangular. The adhesive member 2100 is formed to fit into the groove 2030.

[0034] <Embodiment 3> In the third embodiment, at least one through hole is provided that penetrates from the adhesive surface of the mounting base to the mounting surface. In the third embodiment, the materials constituting each member are the same as those in the first embodiment, so the description will be omitted. Fig. 9 is a perspective view of a mounting base 2300 according to the third embodiment. Fig. 10 is a three-sided view of a mounting member 2200 according to the third embodiment. As shown in Fig. 10, the mounting member 2200 includes a mounting base 2300 and an adhesive member 2400. Fig. 11 is a cross-sectional view taken along the line XI-XI in Fig. 10.

[0035] The mounting base 2300 is provided with a through hole 2330 penetrating from the adhesive surface 2320 to the mounting surface 2310. The cross section of the through hole 2330 when cut in a direction parallel to the mounting surface 2310 side of the mounting base 2300 is rectangular. As shown in FIG. 11, the through hole 2330 is provided with a bridge member 2340 and a flange 2350 on the adhesive surface 2320 side. The bridge member 2340 is a member provided so as to connect the side walls of the through hole 2330. The bridge member 2340 may be provided in a cross shape as shown in FIG. 10. The flange 2350 is an annular member extending from the side wall of the through hole 2330 toward the center of the through hole 2330.

[0036] Since the mounting base 2300 is provided with the flange 2350, the cross-sectional area of ​​the through hole 2330 when cut in a direction parallel to the mounting surface 2310, i.e., in a direction perpendicular to the extension direction of the through hole 2330, is smaller at the end on the bonding surface 2320 side than at the end on the mounting surface 2310 side. Therefore, as shown in Fig. 11, when the adhesive member 2400 is formed so as to cover the flange 2350, the adhesive member 2400 can more firmly bond the mounting base 2300 to the vehicle window glass 400 due to the anchor effect. Also, as shown in Fig. 11, when the adhesive member 2400 is formed so as to cover the bridge-shaped member 2340, the anchor effect can be further enhanced.

[0037] 9 to 11, a through hole having a bridge member and a flange is provided on the adhesive surface side, but the shape of the through hole is not limited to the above.

[0038] Fig. 12 is a front view of a modified example of the mounting member according to the third embodiment. Fig. 13 is a cross-sectional view taken along line XIII-XIII in Fig. 12. The mounting member 2600 shown in Figs. 12 and 13 includes a mounting base 2700 and an adhesive member 2800. A through hole 2730 is provided in the mounting base 2700. A flange 2750 is provided in the through hole 2730 at an end on the adhesive surface 2720 side of the mounting base 2700. The flange 2750 has a star shape when viewed from the mounting surface 2710 side. The adhesive member 2800 is formed so as to cover the flange 2750, as shown in Fig. 13.

[0039] FIG. 14 is a front view of a modified mounting member according to the third embodiment. FIG. 15 is a cross-sectional view taken along line XV-XV in FIG. 14. The mounting member 3000 shown in FIGS. 14 and 15 includes a mounting base 3100 and an adhesive member 3200. The mounting base 3100 is provided with a through hole 3130. The cross section of the through hole 3130 when cut in a direction parallel to the mounting surface 3110 is circular. The through hole 3130 is provided with a flange 3150 at an end on the adhesive surface 3120 side. The flange 3150 has a circular shape when viewed from the mounting surface 3110 side. The adhesive member 3200 is formed so as to cover the flange 3150, as shown in FIG. 15. EXAMPLES

[0040] Next, an embodiment of the present invention will be described. In order to measure the breaking strength of the samples according to the embodiment, an apparatus having a configuration shown in Fig. 16 was used. Fig. 16 is a diagram showing the configuration of a breaking strength measuring apparatus 10. Fig. 17 is a cross-sectional view taken along line XVII-XVII in Fig. 16.

[0041] As shown in FIG. 17, the breaking strength measuring device 10 includes a jig 60 that is a member for fixing a glass plate 40. A mounting base 20 is attached to the upper surface of the glass plate 40 via an adhesive member 30. The mounting base 20 has a size of 30 mm in length, 25 mm in width, and 4.5 mm in thickness. The mounting base 20 is made of stainless steel (SUS304). The glass plate 40 has a size of 100 mm in length, 100 mm in width, and 5.0 mm in thickness. The glass plate 40 is made of soda lime glass. The adhesive member 30 is an epoxy-based two-component adhesive (manufactured by Konishi Co., Ltd., product name: MOS400).

[0042] The tensile point 50 shown in Fig. 17 is a point where a metal rod is welded to the mounting surface of the mounting base 20. An Autograph (manufactured by Shimadzu Corporation, product name: AGS-5kNJ) was used for the breaking strength measurement. The metal rod welded to the tensile point 50 was pulled vertically upward at a pulling speed of 50 mm / min, and the magnitude of the force when the mounting base 20 separated from the glass plate 40 was measured.

[0043] In Examples 1 to 3, three samples were measured using a mounting base 20 that had no texture on the adhesive surface. In Examples 4 to 6, three samples were measured using a mounting base 20 that had texture on the adhesive surface. The depth of the texture in all three samples was 20 μm. The results of measuring the breaking strength are shown in Table 1 below. Examples 1 to 3 are comparative examples, and Examples 4 to 6 are working examples.

[0044] [Table 1]

[0045] All of Examples 4 to 6 had a breaking strength of 400N or more, which was good. Furthermore, in Examples 4 to 6, cohesive failure occurred over the entire surface of the area where the adhesive was applied, and the adhesion was good. On the other hand, all of Examples 1 to 3 had a breaking strength of less than 400N, which was poor. Furthermore, in Examples 1 to 3, interfacial peeling occurred over the entire surface of the area where the adhesive was applied. From the above results, it was clear that providing texture on the adhesive surface of the mounting base 20 improves adhesion and provides sufficient breaking strength.

[0046] Next, to measure the amount of displacement of the sample according to the embodiment, an apparatus having a configuration shown in Fig. 18 was used. Fig. 18 is a diagram showing the configuration of a displacement amount measuring apparatus 11.

[0047] 18, the displacement measuring device 11 includes a jig 61 that is a member for fixing a glass plate 41. A mounting base 21 is attached to the upper surface of the glass plate 41 via an adhesive member (not shown). The mounting base 21, the glass plate 41, and the adhesive member are the same as the mounting base 20, the glass plate 40, and the adhesive member 30, respectively.

[0048] The metal rod 71 is a metal rod that has one end welded to the center of the mounting surface of the mounting base 21 and extends parallel to the mounting surface of the mounting base 21. The force point 51 shown in FIG. 18 is a point that is a distance A away from the center of the mounting surface of the mounting base 21. In this embodiment, the distance A is 42 mm. In the displacement measurement, a load of 294 N is applied to the force point 51 of the metal rod 71 in a direction perpendicular to the direction in which the metal rod 71 extends, and the displacement B of the force point 51 in the direction in which the load is applied is measured. In Examples 21 to 23, three samples using a mounting base 21 without a through hole were measured. In Examples 24 to 26, three samples using a mounting base 21 with a through hole having a shape shown in FIGS. 9 to 11 were measured. The measurement results of the displacement are shown in Table 2 below. Examples 21 to 23 are reference examples, and Examples 24 to 26 are working examples.

[0049] [Table 2]

[0050] The displacement amounts of Examples 24 to 26 were all smaller than those of Examples 21 to 23. From the above results, it was made clear that providing a through hole in the mounting base 21 reduced the displacement amount and improved torsion resistance.

[0051] While the present invention has been described above with reference to the above-described embodiment, the present invention is not limited to the configuration of the above-described embodiment, and naturally includes various modifications, alterations, and combinations that may be made by a person skilled in the art within the scope of the invention as defined in the claims of the present application.
