Technical Field

The present invention relates to a mounting base and a vehicle glass with the same.

Background

In a vehicle such as an automobile, a vehicle-mounted component such as a vehicle-mounted camera or a sensor may be mounted on a surface of a vehicle interior side of a vehicle glass. These vehicle-mounted components are often mounted in positions close to the interior mirror from the viewpoint of not obstructing the view of the occupants and satisfying the requirements of legal regulations. For example, japanese patent laid-open publication No. 2017-71334 discloses an auxiliary unit 3 for mounting an auxiliary for vehicle (an in-vehicle component) such as a camera or a sensor in the vicinity of a mirror unit 2 having an indoor mirror 21.

In japanese patent application laid-open No. 2017-71334, the auxiliary unit 3 is provided with a bracket 40 having one face attachable to the windshield 13 and the other face holding the in-vehicle camera 50. A part of the bracket 40 is cut out, and at the cut-out part, the pillar portion 23 of the mirror unit 2 is bonded to the windshield 13.

However, in this configuration, the bracket (mounting base) 40 of the auxiliary unit 3 and the pillar portion 23 of the mirror unit 2 must be positioned on the front window glass. Therefore, there is a limit in disposing the holder of the auxiliary unit 3 and the mirror unit 2 close to each other, and the accuracy of the relative mounting positions of the indoor mirror and the auxiliary unit 3 is insufficient, and as a result, the respective members may interfere with the functions of each other.

A general object of at least one aspect of the present invention is to provide a mounting base for mounting a vehicle-mounted component on a surface to be mounted in a vehicle, which can improve the accuracy of relative mounting positions of the components.

One aspect of the present invention is a mounting base for mounting a vehicle-mounted component on a vehicle interior side surface of a vehicle glass, including a mirror base for mounting an interior mirror and a component base for mounting a vehicle-mounted component other than the interior mirror, the mirror base and the component base being at least partially exposed on a side of a surface of the vehicle glass to which the vehicle glass is mounted, the mirror base being fixed to the component base and being formed of a material having a higher longitudinal elastic modulus than the component base.

Detailed Description

Hereinafter, embodiments of the present invention will be described. In the drawings, the same or corresponding components are denoted by the same or corresponding reference numerals, and the description thereof may be omitted. The present invention is not limited to the following embodiments.

Fig. 1 shows a structure in which a mounting base 1 according to an embodiment of the present invention is mounted on a mounting surface in a vehicle. In the example of fig. 1, the mounted surface is a surface of the vehicle glass G, more specifically, an inner side surface of a windshield. Fig. 1 is a view of a glass G as viewed from the vehicle interior side of an automobile, but the detailed structure of the mounting base 1 in fig. 1 is omitted.

In fig. 1 and other drawings described later, the x-axis direction (left-right direction) is the vehicle width direction in a state where the mounting base 1 is mounted on a mounting surface (glass G) in the vehicle, and the right direction when viewed from the vehicle interior side is referred to as + x direction. The y-axis direction is a direction perpendicular to the x-axis direction and along the surface of the mounting base 1, and the direction toward the upper end of the surface to be mounted (glass G) is referred to as the + y direction. The z-axis direction (vertical direction) is a direction orthogonal to the x-axis direction and the y-axis direction, and a direction toward the surface to be mounted (glass G) is defined as + z direction. The surface on the + z direction side (the surface facing the surface to be mounted) of the mounting base 1 may be referred to as an upper surface, and the surface on the-z direction side (the vehicle interior side) may be referred to as a lower surface.

In the present specification, the "mounting base" (also referred to as a bracket) refers to a member serving as a base (base) for mounting an in-vehicle component on the surface of the glass. The "mounting base" is a member that is sandwiched between the vehicle-mounted component and the glass, facilitates mounting of the vehicle-mounted component on the mounting surface, supports the mounted vehicle-mounted component, and is fixed to the mounting surface.

In the present specification, the term "vehicle-mounted component" refers to a device, an appliance, or a member mounted on a vehicle. The in-vehicle components may be 1 or more of, for example, an in-vehicle camera, a raindrop sensor (rain sensor), a defrost sensor, a temperature sensor, a humidity sensor, a millimeter wave sensor, and the like, an etc (electronic toll collection system) antenna, an antenna of a radio, a terrestrial digital television, and the like, a communication device, for example, an intercommunication radio wave module, and a radio wave reception amplifier. In this specification, the interior mirror (interior mirror) is also included in the vehicle-mounted component.

As shown in fig. 1, the mounting base 1 may be mounted on the surface of the glass G. A plurality of vehicle-mounted components can be mounted on the mounting base 1 from the vehicle interior side, and a cover or the like for covering and protecting the vehicle-mounted components can be provided as necessary.

Further, a shielding layer 4 for protecting a sealant for bonding and holding the glass G to the vehicle body or the like may be provided at the peripheral edge of the glass G. The shielding layer 4 can be formed by, for example, applying a ceramic paste containing a molten glass frit containing a black pigment and firing the ceramic paste. The shielding layer 4 may be provided on the surface of the glass G on the vehicle interior side. In the illustrated embodiment, the mounting base 1 is directly bonded to the surface of the glass G, but may be mounted on the shielding layer 4 provided on the surface on the vehicle interior side. As described below, in the case where the glass G is a laminated glass in which a vehicle exterior glass plate and a vehicle interior glass plate are bonded through an interlayer film, the shielding layer 4 may be provided on the vehicle interior surface of the vehicle interior glass plate or may be provided on the vehicle interior surface of the vehicle exterior glass plate. The glass plate may be provided on both of the vehicle-exterior side glass plate and the vehicle-interior side glass plate. The mounting base 1 is preferably shielded by the shielding layer 4 when viewed from the outside of the vehicle. When the mounting base 1 is entirely or partially shielded by the shielding layer 4 when viewed from the outside of the vehicle, it is preferable that an adhesive for bonding the mounting base 1 described later to the glass G can be protected without impairing the appearance.

Next, the structure of the mounting base will be described in detail.

Fig. 2 shows a mounting base 1 according to embodiment 1 of the present invention as viewed from the mounted surface side (+ z direction side). Fig. 3 shows a view of the mounting base 1 as viewed from the vehicle interior side (the (-z direction side) when mounted. In addition, FIG. 4 shows a view of arrows along line A1-A1 in FIG. 3, and FIG. 5 shows a view of arrows along line B-B in FIG. 3.

As shown in fig. 2 and 3, a mounting base 1 according to embodiment 1 of the present invention includes: a mirror base 20 for mounting an indoor mirror, and a component base 30 for mounting on-vehicle components other than the mirror (hereinafter, also simply referred to as components).

The mirror base (sometimes also referred to as a mirror button (japanese: ミラーボタ ン))20 is a base member for mounting the interior mirror. The mirror is typically supported by a post, one end of which may be mounted on the mirror base 20. The mirror base 20 is a substantially plate-shaped member, but as shown in fig. 3, a projection and a recess may be provided at one end of a support for attaching a mirror. In the illustrated embodiment, the mirror base 20 has an elongated shape in which the length in the y-axis direction is longer than the length in the x-axis direction in a plan view.

The component base 30 is a base member for mounting at least one vehicle-mounted component, specifically, a vehicle-mounted component other than the interior mirror. As shown in fig. 2 and 3, the component base 30 is a substantially plate-shaped member similarly to the mirror base 20, but may be formed with projections and recesses (claws, holes, etc.) in order to mount the in-vehicle components or to prevent the mounted in-vehicle components from interfering with functions at appropriate positions. The vehicle-mounted component mounted on the component base 30 is not particularly limited, but is preferably a vehicle-mounted camera, for example. The number of the vehicle-mounted components directly mounted on the component base 30 may be 1, or 2 or more.

As shown in fig. 2, the mirror base 20 and the component base 30 are at least partially exposed on the mounted surface side (+ z direction side) of the glass for a vehicle, respectively. That is, the mirror base 20 and the component base 30 each have an uncovered area where an adhesive or the like can be directly applied. Thus, when the mount base 1 is mounted on the mounting surface (for example, the surface of the vehicle glass G), the mirror base 20 and the component base 30 can be mounted on the mounting surface with a predetermined area. Therefore, the main load of the mirror can be directly received by the mirror base 20, and the main load of the components other than the indoor mirror can be directly received by the component base 30.

The area of the mirror base 20 exposed on the mounting surface side, that is, the area of the portion that can be bonded to the mounting surface by an adhesive or the like can be appropriately selected according to the rigidity, hardness, and the like of the material constituting the mirror base 20, but is preferably 2 to 5cm²Left and right. When the entire mirror base 20 on the side opposite to the surface to be mounted is exposed, the mirror base 20 preferably has a size of 2 to 5cm in a plan view²Left and right. From the viewpoint of improving the adhesion stability of the mirror base 20, the thickness (length in the z-axis direction) of the mirror base 20 is preferably about 4 to 16mm, although it depends on the rigidity, hardness, and the like of the material constituting the mirror base 20.

In this embodiment, the mirror base 20 is fixed to the component base 30. In the illustrated embodiment, an opening 38 is formed near the center of the component base 30 in the x-axis direction in the + y direction, and the mirror base 20 is disposed and fixed in the opening 38. The shape of the opening 38 of the component base 30 in plan view may correspond to the shape of the mirror base 20.

The indoor mirror is a component that adjusts the position relatively frequently, and therefore, it is easy to frequently apply an external force to the mirror itself and the mirror base. Further, since the mirror is disposed at a position that is easy to be gripped by the occupant, particularly, in an upper region of the windshield, the occupant may intentionally or unintentionally grip the mirror or the stay to apply a weight thereto when getting on or off the vehicle, or the like, and may apply a large load to the mirror or the stay and the mirror base 20. When such a load is excessively large, the adhesion between the mirror base 20 and the mounting surface (the surface to be adhered) may peel off or the mounting surface may be damaged. In contrast, in the present embodiment, since the mirror base 20 and the component base 30 are fixed, a part of the load applied to the mirror base 20 can be transmitted to the component base 30 as well. This reduces the load applied to the mirror base 20 and the surface to be mounted to which the mirror base 20 is bonded. Therefore, the possibility of the mirror base peeling can be reduced, and even if the material of the member constituting the surface to be mounted is weak or the thickness of the member is small, damage to the member constituting the surface to be mounted can be prevented.

A fixing method for fixing the mirror base 20 to the component base 30 (a coupling method of the mirror base 20 and the component base 30) is not particularly limited. The mirror base 20 can be fixed to the component base 30 by engagement, fitting (including press fitting, slide fitting), or adhesion. The mirror base 20 can be detachably fixed to the component base 30, and can also be detachably fixed to the component base 30. In the case of fixing by adhesion, an adhesive or an adhesive tape may be used. Further, the component base may be formed such that a part of the mirror base 20 is assembled into the component base 30, or the mirror base 20 may be formed such that a part of the component base 30 is assembled into the mirror base 20. These fixing means may be 2 or more kinds combined.

In the example shown in fig. 2 and 3, the mirror base 20 is fixed to the component base 30 by engagement. Specifically, the component base 30 has an opening 38, and the mirror base 20 is disposed and fixed in the opening 38. As shown in fig. 2 and 3, the edge portion of the opening 38 of the component base 30 is provided with an engaging portion 32(32a, 32a, 32a ', 32a', 32c, 32d, 32d), and the edge portion of the mirror base 20 is fixed by such an engaging portion 32.

More specifically, two engaging portions (claws) 32a and 32a are provided near the + y direction at portions of both edge portions of the opening 38 of the component base 30 extending in the substantially y-axis direction. The engaging portions 32a, 32a are formed in pairs of a claw 32a on the upper surface side (+ z direction side) and a small claw 32a' on the lower surface side (-z direction side), respectively. The mirror base 20 is held so as to be sandwiched from above and below by claws 32a, 32a and small claws 32a ', 32a' arranged on the respective surface sides of the edge portion of the mirror base 20 (fig. 4).

Further, the claw 32c on the upper surface side (+ z direction side) and the claws 32d, 32d on the lower surface side (-z direction side) are provided at the portion of the edge portion extending in the substantially x-axis direction on the-y direction side of the opening 38 of the component base 30. The claw 32c is disposed between the 2 claws 32d, 32d when viewed from the x-axis direction. The mirror base 20 is held so as to be sandwiched vertically by the claws 32c and the claws 32d and 32d (fig. 5).

In the present embodiment, when the mirror base 20 is attached to the component base 30, first, the end portion on the-y direction side of the mirror base 20 is inserted between the claw 32c and the claws 32d and 32d from the lower surface side (-z direction side) toward the edge portion on the-y direction side of the opening 38 of the component base 38. Then, the mirror base 20 is pushed into the opening 38 from the lower surface side toward the upper surface side (from the-z direction side toward the + z direction side), and both side portions near the end portion on the + y direction side of the mirror base 20 are engaged by the claws 32a, 32a and the small claws 32a ', 32 a'.

Thus, in the present embodiment, the mirror base 20 and the component base 30 are fixed to each other by engagement, and the relative positions of the two bases 20 and 30 are fixed. Therefore, when the mounting base 1 is mounted on a mounting surface such as a glass G, it is not necessary to perform positioning of the two bases 20 and 30, respectively, and it is possible to avoid a shift in phase position due to positioning of the members, respectively. This can improve the accuracy of the relative mounting position of the vehicle-mounted components supported by the bases 20 and 30.

In addition, in the mounting process, the two bases 20 and 30 can be used as 1 member, which can reduce the complexity in mounting and shorten the time required for mounting.

In the illustrated embodiment, the engaging portions 32 (the claws 32a, and 32c) on the upper surface side (+ z direction side) of the mounting base 1 are formed to protrude from the upper surface. That is, protrudes in the + z direction from the surfaces of the mirror base 20 and the component base 30. The height of the engaging portions 32 (the claws 32a, and 32c) protruding from the surface of the component base 30 on the upper surface side may be about 0.1 to 3.0mm as long as the function of the adhesive applied between the engaging portions and the mounting surface is not lost.

However, the engaging portion 32 may be formed so that the engaging portion 32 does not protrude in the + z direction and at least the bonded portions of the mirror base 20 and the component base 30 are flush with each other on the upper surfaces. When the mirror base 20 and the component base 30 are flush with each other on the upper surface side, the thickness of the adhesive layer applied between the upper surface of the mounting base 1 and the surface to be mounted can be made uniform during mounting, and therefore, when a load or the like is applied, variation in stress generated in the adhesive layer can be reduced.

The materials constituting the mirror base 20 and the component base 30 are not particularly limited, but the mirror base 20 and the component base 30 are preferably made of different materials. For example, the mirror base 20 may be formed of a material having a higher elastic modulus than the component base 30, specifically, a material having a higher longitudinal elastic modulus than the component base 30. Further, the mirror base 20 may be formed of a material having a higher hardness than the component base 30. Thus, by forming the mirror base 20 from a material having a high flexural modulus or high hardness, the indoor mirror and the support column attached thereto, which are particularly prone to load, can be stably fixed to the surface to be mounted.

The component base 30 is used to mount an on-vehicle component other than a mirror, and may be formed to wholly or partially surround the mirror base 20 in a plan view, and the component base 30 may be a main component (main base) of the mounting base 1 and may have the same contour as that of the mounting base 1. The component base 30 has a larger area than at least the mirror base 20. On the other hand, the surface to be attached to which the base is bonded, for example, the surface of a vehicle glass, is often curved. Therefore, if the flexural modulus of elasticity or the hardness of the component base 30 is too large, a gap is formed between the component base 30 and the surface to be mounted, and the two cannot be tightly bonded, and as a result, the bonding strength may be reduced. However, the component base 30 has low bending elasticity or low hardness, so that the component base 30 can be bent so as to conform to the surface to be mounted, and the mounting base 1 can be adhered closely to the surface to be mounted.

The longitudinal elastic modulus (Young's modulus) of the mirror base 20 is preferably 3GPa or more, and more preferably 30GPa or more. The mirror base 20 having the longitudinal elastic modulus in the above range can fix the mirror and the support to the glass surface more stably. In addition, in the case where a resin material is selected as the material of the base, the component base 30 preferably has a flexural modulus of elasticity of 300MPa or less, and more preferably 150MPa or less. The component base 30 having the flexural modulus of elasticity in the above range can improve the compliance with the curved glass surface. However, the component base 30 may be made of a material having an elastic modulus equivalent to that of the mirror base 20 depending on the size of the component base 30, the type of component to be mounted, or the like, or when the bending of glass is small. The longitudinal elastic modulus and the flexural elastic modulus may be measured according to ASTM D790 or the like.

The hardness of the mirror base 20 is preferably 5.0HRC or more, more preferably 20HRC or more on the rockwell hardness scale. The hardness is a hardness measured according to JISZ 2245.

The material forming the mirror base 20 is not particularly limited as long as it has a longitudinal elastic modulus or hardness that is sufficient to stably fix the mirror and the stay to the surface to be mounted, but is preferably metal or resin. Examples of the material of the metal mirror base 20 include zinc, aluminum, and alloys thereof, and stainless steel (including sintered SUS). These materials may be used alone or in combination.

The mirror base may be made of resin. Examples of the resin include polyesters such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), polyolefins such as Polyethylene (PE) and polypropylene (PP), Polyamides (PA) such as Polycarbonate (PC), nylon 6 and nylon 6, high heat-resistant polyamides (PA6T/PA6I), Polyimides (PI), polyether imides (PEI), acrylonitrile-butadiene-styrene (ABS), Polyacetal (POM), and polyvinyl chloride (PVC).

When the mirror base 20 is made of resin, resin reinforced with a filler such as fibers or inorganic particles may be used. As the reinforcing fibers, glass fibers, carbon fibers, and the like are preferable. As the fiber-reinforced resin, polyetherimide reinforced with glass fiber and high heat-resistant polyamide are preferable. When the resin contains reinforcing fibers, the resin may contain fibers in an amount of about 5 to 70 mass%, preferably about 30 to 50 mass%, based on the total resin.

When the mirror base 20 is made of metal, it can be formed by die casting, or the like. In the case of resin, the resin may be formed by injection molding or the like.

The material forming the component base 30 is also not particularly limited, but is preferably a material that can be bent in conformity with the bending of the surface to be mounted, and may be made of, for example, resin. Examples of the resin forming the member base 30 include polyesters such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), polyolefins such as Polyethylene (PE) and polypropylene (PP), Polyamides (PA) such as Polycarbonate (PC), nylon 6 and nylon 6, high heat-resistant polyamides (PA6T/PA6I), Polyimides (PI), polyether imides (PEI), acrylonitrile-butadiene-styrene (ABS), Polyacetal (POM), and polyvinyl chloride (PVC).

The resin forming the component base 30 may be reinforced with a filler such as fibers or inorganic particles. As the reinforcing fibers, glass fibers, carbon fibers, and the like are preferable. When the resin contains reinforcing fibers, the resin may contain fibers in an amount of 50 mass% or less, preferably 30 mass% or less, based on the total amount of the resin.

When the component base 30 is made of resin, it can be formed by injection molding or the like.

As shown in fig. 2 and 3, when the mirror base 20 is fixed to the component base 30 by engagement, a gap may be at least partially provided between the mirror base 20 and the component base 30.

The mirror base 20 and the component base 30 may be fixed to each other by other members, but it is preferable that both members are fixed to each other by being at least partially in contact with each other because the accuracy of position fixing is improved.

The mounting base 1 may further include an additional base 40 (fig. 2 and 3) for mounting the in-vehicle components, in addition to the in-vehicle components mounted on the indoor mirror and the component base (main base) 30. The vehicle-mounted component that can be mounted by the additional base 40 may be a sensor, for example.

The additional base 40 is preferably made of a member different from the component base (main base) 30 and fixed to the component base 30, as in the mirror base 20. By fixing the additional base 40 to the component base, it is not necessary to position the additional base 40 and the component base 30 separately, and a shift in relative position can be avoided. This can improve the accuracy of the relative mounting position between the in-vehicle component (for example, an in-vehicle camera) supported by the component base 30 and the in-vehicle component (for example, a sensor) supported by the additional base 40.

The fixing method of the additional base 40 to the component base 30 is not particularly limited. The additional base 40 may be detachably fixed to the component base 30, or may be detachably fixed to the component base 30. For example, as shown in fig. 2 and 3, the component base 30 is provided with engaging portions 34(34a, 34a, 34a ', 34a', 34b, 34b, 34b ', 34b') at positions corresponding to the outer edge shape of the additional base 40, and the additional base 40 can be fixed and held by the engaging portions 34. Specifically, the component base 30 has an opening, and the component base 30 can be disposed and fixed in the opening. The engaging portion 34 may be formed at an edge portion of the opening portion of the component base 30.

Fig. 6 and 7 are sectional views showing the structure in the vicinity of the additional base 40. Fig. 6 is a view of arrows along line C-C of fig. 3, and fig. 7 is a view of arrows along line D-D of fig. 3. The fixing of the additional base 40 will be described more specifically below.

The component base 30 is provided with engaging portions 34a, 34a on the upper surface side (+ z direction side) and in the vicinity of the + y direction. The engaging portions 34a, 34a are paired with engaging portions 34a ', 34a' (fig. 3) provided on the lower surface side (-z direction side), respectively. The engagement portions 34a, 34a on the upper surface side and the engagement portions 34a ', 34a' on the lower surface side of the additional base 40 may sandwich and hold both side edge portions of the additional base 40 in the x-axis direction (fig. 6).

Further, engaging portions 34b, 34b are provided on the upper surface side (+ z direction side) of the component base 30 in the vicinity of the-y direction. The engaging portions 34b, 34b are paired with 34b ', 34b' (fig. 3) provided on the lower surface side (-z direction side), respectively. The engagement portions 34b, 34b and the engagement portions 34b ', 34b' can hold the additional base 40 with the-y-direction corner edges thereof in the vertical direction (fig. 7).

When the additional base 40 is attached to the component base 30, first, the additional base 40 is inserted from the lower surface side (-z direction side) so that 2 corner sides of the additional base 40 enter into the pair formed by the engaging portion 34b and the engaging portion 34b' formed in the component base 38 in the-y direction. Then, the additional base 40 is pushed in the + z direction, and is fixed and held by the engaging portions 34a, 34a, 34a ', 34a' to the component base 30.

The additional base 40 is preferably made of a material different from that of the component base 30, and may be made of metal, for example. Examples of the metal used for the additional base 40 include stainless steel, aluminum, and SPCC steel (general steel defined in JIS G3141). The longitudinal elastic modulus of the additional base 40 is preferably 80GPa or more, more preferably 120GPa or more.

The additional base 40 may be configured to be directly attached to the mounting surface with a predetermined area by exposing at least a part of the additional base on the mounting surface side, as in the mirror base 20. In this case, the additional base 40 can directly receive a main load of the in-vehicle component mounted on the additional base 40.

Fig. 8 shows a state after components are mounted on the mounting base 1 of the present embodiment. In the example of fig. 8, the camera unit C (including a camera, an accessory, a cover, and the like) is attached to the component base 30 of the mounting base 1, and the sensor unit S (including a sensor, an accessory, a cover, and the like) is attached to the additional base 40. Thus, the component can be mounted on the mounting base 1 in the-z direction.

Fig. 9 shows a partially enlarged view of the mounting base 201 according to embodiment 2 of the present invention. In addition, a view of line arrows A2-A2 of FIG. 9 is shown in FIG. 10. The mounting base 201 is mounted on a mounting surface in a vehicle, and includes a mirror base 220 and a component base 230, and the mirror base 220 is fixed to the component base 230, as in embodiment 1. However, embodiment 2 differs from embodiment 1 in that the form of fixing the mirror base 220 to the component base 230 differs.

As shown in fig. 9, in embodiment 2, no engaging portion is provided at the edge portion of the opening 238 of the component base 230, and the mirror base 220 is fitted into the opening 238 of the component base 230. For example, the size of the opening 238 of the component base 230 (at least a part of the length in the x-axis direction and the length in the y-axis direction) is slightly smaller than the size of the mirror base 220, and the mirror base 220 is pressed into the opening 238 of the component base 230, whereby both bases can be fitted to each other. In the case where the component base 230 is formed of a thermoplastic material, the mirror base 220 can be fitted in the opening 238 of the component base 230 in a state in which the opening is softened by applying heat.

In fig. 10, the boundary line between the mirror base 220 and the component base 230 is parallel to the z-axis direction, but may be inclined with respect to the z-axis direction. For example, the mirror base 220 may be configured such that the width (length in the x-axis direction) and/or the length (length in the y-axis direction) thereof gradually increase toward the-z direction side when viewed in cross section along the z-axis direction, and the shape of the opening 238 of the component base 230 may be configured to correspond to the shape of the mirror base 220.

In embodiment 2, the edge portion of the opening 238 of the component base 230 other than the vicinity of the corner edge may be entirely or partially brought into close contact with the mirror base 220. In addition, in this embodiment, since the engaging portion is not required to be formed, the mounting base 201 having a simpler structure can be obtained.

Further, according to the present embodiment, the component base 230 and the mirror base 220 can be configured to be flush with each other on the glass-facing surface of the mounting base 201.

Fig. 11 shows a partially enlarged view of a mounting base 301 according to embodiment 3 of the present invention. In addition, a line arrow view of A3-A3 of FIG. 11 is shown in FIG. 12. The mounting base 301 is mounted on a mounting surface in a vehicle, includes a mirror base 320 and a component base 330, and the mirror base 320 is fixed to the component base 330, as in embodiments 1 and 2. However, embodiment 3 differs from embodiment 1 and the like in that the form of fixing the mirror base 320 to the component base 330 differs.

In embodiment 3, the component base 330 is formed by injection molding. The material of the component base 330 is fixed so as to sandwich the peripheral edge of the mirror base 320 from above and below (fig. 12). As shown in fig. 12, the contour of the inner edge portion of the component base 230 sandwiching the peripheral edge of the mirror base 320 preferably has an inclination of an angle θ with respect to the z-axis direction in a cross-sectional view. The angle θ is preferably 0 ° or more and 10 ° or less. More preferably, it is 0 ° or more and 8 ° or less.

In the illustrated example, the component base 330 is injection molded so as to sandwich the mirror base 320 along the z-axis direction and so as to sandwich the mirror base 320 along the y-axis direction. The mirror base 320 is injection molded so as to sandwich the mirror base 320 along the z-axis direction and the x-axis direction. However, the mirror base 320 may not be sandwiched in the z-axis direction. For example, the molding material of the component base 330 is not disposed on the upper surface or the lower surface of the mirror base 320, but the component base 330 is injection molded so as to sandwich the mirror base 320 in the y-axis direction, in such a manner that both ends in the y-axis direction of the mirror base 320 are pressed from both sides in the y-axis direction by the molding material of the component base 330.

In the illustrated example, the entire peripheral edge of the mirror base 320 is sandwiched and held in the component base 330, but a part of the peripheral edge of the mirror base 320 may be sandwiched in the component base 330 as long as the mirror base 320 can be fixed to the component base 330. For example, the component base 330 may be injection molded so that only the entire or a part of both edge portions of the mirror base 320 extending in the substantially y-axis direction is sandwiched.

Further, the component base 330 may be injection molded such that a protrusion extending from the end surface is formed in advance in the mirror base 320 from the edge portion thereof in the surface direction (direction substantially parallel to the x-y plane) and the protrusion is inserted into the material of the component base 330.

In the present embodiment, since the component base 330 and the mirror base 320 can be firmly coupled to each other, the mirror base 320 and the component base 330 can be prevented from being separated from each other when an impact or the like is applied in the step of attaching the attachment base 301 to the surface of the glass for a vehicle.

Fig. 13 shows a partially enlarged view of a mounting base 401 according to embodiment 4 of the present invention. In addition, a line arrow view of A4-A4 of FIG. 13 is shown in FIG. 14. The mounting base 401 is mounted on a mounting surface in a vehicle, includes a mirror base 420 and a component base 430, and the mirror base 420 is fixed to the component base 430, as in embodiments 1 to 3. However, embodiment 4 differs from embodiment 1 and the like in that the form of fixing the mirror base 420 to the component base 430 differs.

In embodiment 4, grooves extending substantially in the y-direction are formed in end faces (faces substantially in the z-axis direction) of portions of both edge portions of the mirror base 420 extending substantially in the y-axis direction. A projection 433 (fig. 14) extending substantially in the y-axis direction corresponding to the groove 423 of the mirror base 420 is formed on an end surface of the component base 430 facing the mirror base 420. The projection 433 of the component base 430 is slidable in the y-axis direction within the groove 423 of the mirror base 420.

Unlike the above-described embodiment 1 and the like, the component base 430 has a slit 439 that opens in the + y direction. When the mirror base 420 is attached to the component base 430, the mirror base 420 can be slidably fitted to the component base 340. That is, the mirror base 420 can be slid along the projection 433 of the component base 430 in the-y direction until the end of the mirror base 420 on the-y direction side abuts against the slit 439 of the component base 430.

In the illustrated example, the groove 423 formed in the mirror base 420 corresponds to the protrusion 433 formed in the component base 430. However, a projection may be formed on the mirror base 420, a groove corresponding to the projection of the mirror base 420 may be formed on the component base 430, and the projection of the mirror base 420 may be slidable in the groove of the component base 430. In this case, the mirror base 420 can be fixed to the component base 430 by inserting the mirror base 420 into the slit 439 of the component base 430.

The mounting base according to the above-described embodiment can be mounted on a mounting surface in a vehicle and used. As described above, the mounted surface in the vehicle may be a vehicle glass. Accordingly, an embodiment of the present invention may be a mounting base-mounted vehicle glazing, namely mounting base-mounted vehicle glazing 100 (fig. 1). The glass for a vehicle may be, for example, a front glass, a rear glass, a side glass, etc., and a front glass is particularly preferable.

The vehicle glass may be formed of a glass plate such as a soda-lime-silicate glass, an aluminosilicate glass, a borate glass, a lithium-aluminosilicate glass, or a borosilicate glass. The glass sheet may be non-strengthened, or may be air-cooled strengthened or chemically strengthened. The unreinforced glass is formed by forming molten glass into a plate shape and annealing the formed glass. The tempered glass is one in which a compressive stress layer is formed on the surface of an unreinforced glass. When the tempered glass is air-cooled tempered glass, the surface of the glass can be tempered by rapidly cooling the uniformly heated glass plate from a temperature near the softening point to generate a compressive stress on the surface of the glass by utilizing a temperature difference between the surface of the glass and the inside of the glass. On the other hand, when the strengthened glass is a chemically strengthened glass, the surface of the glass can be strengthened by applying a compressive stress to the surface of the glass by an ion exchange method or the like. As the vehicle glass, a glass plate absorbing ultraviolet light or infrared light may be used, and transparent glass is more preferable, but glass colored to such an extent that transparency is not impaired may be used. As the glass for vehicles, organic glass can be used. The organic glass may, for example, be a transparent resin such as polycarbonate. The shape of the glass is not particularly limited to a rectangular shape, and various shapes and shapes processed to have a curvature may be used. As the bending of the glass sheet used for the glass for a vehicle, gravity forming, press forming, or the like can be used. The method of forming the glass sheet is not particularly limited, but glass formed by a float process or the like is preferable.

Further, a laminated glass including a plurality of the above glass plates may be used as the glass for a vehicle. An interlayer film of ethylene vinyl acetate, polyvinyl butyral, or the like may be provided between the glass sheets constituting the laminated glass.

The thickness of the glass plate constituting the glass for a vehicle is 4.0 to 6.0mm as a whole. When the vehicle glass is a laminated glass, the thickness of 1 glass plate is about 1.5 to 2.4 mm. The thickness of the glass plate on the vehicle outer side and the thickness of the glass plate on the vehicle inner side may be the same or different. From the viewpoint of weight reduction of the vehicle, for example, the thickness of the glass plate on the vehicle interior side may be set to 0.5mm to 1.6 mm.

When the thin glass plate as described above is used as the glass plate on the vehicle interior side, the surface to be attached to the attachment base 1 is a surface of the thin glass plate having a small strength, and therefore, when an excessive load or the like is applied to the mirror, the glass plate may be damaged. However, in the present embodiment, since the mirror base 20 and the member base 30 are fixed, part of the load applied to the mirror base 20 can be transmitted to the member base 20 to disperse the load, and therefore, even if a large load is applied to the mirror, the possibility of damage to the glass plate can be reduced.

As described above, the mounting base of the present embodiment may be configured to have a curved surface in a compliant manner. The radius of curvature of the surface of the region of the vehicle glass to which the mounting base is attached may be R3000 or more and R5000 or less. The surface of the area for mounting the mounting base may be flat. In addition, the unit of the curvature radius is mm.

From the viewpoint of not obstructing the view of the occupant including the driver, the mounting base 1 is preferably mounted at the center of the upper end as shown in fig. 1. Particularly, when the mounting base 1 is mounted on a windshield, the mounting base 1 preferably has a width (length in the x direction) of about 6 to 30cm and a length (length in the y direction) of about 10 to 18 cm.

In the case of manufacturing a vehicle glass with a mounting base, the mounting base may be bonded to the vehicle glass using an adhesive or an adhesive tape. In this case, an adhesive and/or an adhesive tape suitable for the material forming each base may be used for the portion of the mirror base and the component base exposed on the side of the mounted surface. When the mirror base and the component base are formed of different materials, for example, when the mirror base is made of metal and the component base is made of resin, an adhesive and/or an adhesive tape suitable for each material may be used. In addition, in the case of using an adhesive and/or a bonding tape suitable for both metal and resin, the exposed portions of both bases can be bonded by 1 type of adhesive or bonding tape, so that the work can be simplified.

When the resin base is bonded, an adhesive for resin, for example, a urethane adhesive can be used. In the case of bonding a metal base, a metal adhesive, for example, an adhesive of urethane type, silicone type, acrylic resin type, or the like can be used.

In the case of bonding the mounting substrate, an adhesive for resin and metal, for example, an adhesive containing a modified silicone and an epoxy resin, such as "MOS 200" manufactured by seiko corporation (コニ シ), may be used, and other urethane elastic adhesives, hot melt adhesives, and the like may be used. In the case where the mounting base of the present embodiment is bonded to the vehicle glass using an adhesive that is both resin and metal, the number of adhesives used in the bonding step can be 1, and therefore, the manufacturing of the vehicle glass with the mounting base is simplified. In addition, in the case of using an adhesive agent that is both resin and metal, the adhesive agent can be continuously applied even at the boundary between the members of the mounting base, for example, on and near the boundary between the mirror base and the component base, so the application process of the adhesive agent becomes simpler.

In the case where the mount base is bonded to the vehicle glass, a primer may be appropriately applied to each portion of the mount base and/or the glass before the adhesive is applied.
