Description

Vehicle window glass and sashless doors

[0001] The present disclosure relates to vehicle windows and sashless doors.

[0002] 2. Description of the Related Art Sashless doors are widely used as vehicle doors (typically side doors). Patent Document 1 discloses a technique related to a sashless door for a vehicle.

[0003] Special Publication No. 2023-517012

[0004] In recent years, laminated glass has been used as vehicle window glass in side doors in some cases to improve the sound insulation of vehicles. Vehicle window glass used in sashless doors is provided in the side door and does not have a sash (window frame) to support the window glass, so the edge of the window glass is exposed. Therefore, when laminated glass is used as vehicle window glass, the edge of the laminated glass is exposed, which causes a problem of the interlayer film constituting the laminated glass being exposed to the external environment and deteriorating the interlayer film.

[0005] The present disclosure has been made in view of the above points, and has an object to provide a vehicle window glass and a sashless door that are capable of suppressing deterioration of the interlayer film that constitutes the laminated glass.

[0006] A vehicle window glass according to one aspect of the present disclosure is a vehicle window glass used in a sashless door, and includes laminated glass having a first glass plate disposed on the exterior side of the vehicle when the vehicle window glass is attached to the vehicle, a second glass plate disposed on the interior side of the vehicle, and an intermediate film sandwiched between the first glass plate and the second glass plate, and a peripheral member provided on at least one of a front side edge and a rear side edge of the laminated glass relative to the vehicle so as to cover an edge of the laminated glass.

[0007] A sashless door according to one aspect of the present disclosure includes the vehicle window glass described above and a door panel to which the vehicle window glass is attached.

[0008] According to the present disclosure, it is possible to provide a vehicle window glass and a sashless door that are capable of suppressing deterioration of the interlayer film that constitutes the laminated glass.

[0010] <First Embodiment> Hereinafter, a first embodiment will be described with reference to the drawings. Fig. 1 is a plan view showing an example of the configuration of a vehicle window glass according to the first embodiment, and is a plan view of the vehicle window glass as seen from inside the vehicle. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. The vehicle window glass 1 according to this embodiment is a vehicle window glass used in a sashless door.

[0011] As shown in Fig. 1, a vehicle window glass 1 according to this embodiment is provided with holders 60_1 and 60_2 that hold the vehicle window glass 1 on the underside of the vehicle window glass 1. In this embodiment, the vehicle window glass 1 is held by the holders 60_1 and 60_2, and these holders 60_1 and 60_2 are fixed to a lifting device (not shown). The vehicle window glass 1 moves up and down by the driving force of the lifting device (not shown).

[0012] As shown in Fig. 1, a vehicle window glass 1 according to this embodiment includes laminated glass 10 and peripheral members 30a, 30b. As shown in Fig. 2, the laminated glass 10 includes a first glass sheet 11 that is disposed on the exterior side of the vehicle when the vehicle window glass 1 is installed in the vehicle, a second glass sheet 12 that is disposed on the interior side of the vehicle, and an interlayer film 13 that is sandwiched between the first glass sheet 11 and the second glass sheet 12. The first glass sheet 11 and the second glass sheet 12 are bonded to each other using the interlayer film 13. Use of the laminated glass 10 improves the sound insulation of the vehicle window glass 1.

[0013] The thickness of the laminated glass 10 is preferably 2.8 mm to 10 mm, and more preferably 3.0 mm to 8.0 mm. When the thickness of the laminated glass 10 is 2.8 mm to 10 mm, the laminated glass 10 can have sufficient transmittance and strength.

[0014] The first glass plate 11 and the second glass plate 12 are inorganic glass. Examples of inorganic glass include soda lime glass and aluminosilicate glass. The inorganic glass may be either untempered glass or tempered glass. Untempered glass is formed by molten glass being formed into a plate shape and then slowly cooled. Tempered glass is formed by forming a compressive stress layer on the surface of untempered glass. The tempered glass may be either physically tempered glass (e.g., air-cooled tempered glass) or chemically tempered glass.

[0015] Although not shown, the first glass sheet 11 and the second glass sheet 12 may be formed so as to convexly extend toward the exterior of the vehicle. Gravity forming, press forming, or the like may be used to bend the glass sheet. The glass surface may be physically strengthened by rapidly cooling the uniformly heated glass sheet from a temperature near its softening point during bending, thereby generating compressive stress on the glass surface due to the temperature difference between the glass surface and the interior of the glass. After bending, the glass surface may be chemically strengthened by generating compressive stress on the glass surface using an ion exchange method or the like.

[0016] The thickness of the first glass plate 11 is preferably 1.1 mm to 5.0 mm, more preferably 1.1 mm to 4.2 mm, even more preferably 1.1 mm to 3.6 mm, and may be 1.8 mm to 3.0 mm. When the thickness of the first glass plate 11 is 1.1 mm to 4.2 mm, the vehicle window glass can be made lighter and have sufficient strength. Furthermore, the thickness of the second glass plate 12 is preferably 0.5 mm to 2.7 mm, more preferably 0.5 mm to 2.3 mm, and may be 0.5 mm to 1.8 mm. When the thickness of the second glass plate 12 is 0.5 mm to 2.7 mm, the vehicle window glass can be made lighter and the second glass plate 12 can be made easy to handle.

[0017] The interlayer film 13 may be made of, for example, polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA). The interlayer film 13 may have either a single-layer structure or a multiple-layer structure. The thickness of the interlayer film 13 is preferably 0.5 mm to 3.0 mm, and more preferably 0.5 mm to 2.8 mm. When the thickness of the interlayer film 13 is 0.5 mm to 3.0 mm, the vehicle window glass can be made lighter while ensuring sufficient impact resistance. The interlayer film 13 may also include a heat-generating device, an antenna, a liquid crystal device, a light control device, an image projection layer, a light-emitting layer, a photovoltaic layer, a heat-reflecting layer, etc.

[0018] As shown in FIG. 1 , the vehicle window glass 1 according to this embodiment is provided with a peripheral member 30a on a side edge 21 on the front side of the vehicle. Furthermore, a peripheral member 30b is provided on a side edge 22 on the rear side of the vehicle. As shown in FIG. 2 , the peripheral member 30a is provided so as to cover an edge 17 of the laminated glass 10. By providing the peripheral members 30a and 30b in this manner, it is possible to prevent the interlayer film 13 constituting the laminated glass 10 from being directly exposed to the external environment. This makes it possible to prevent deterioration of the interlayer film 13. Here, deterioration of the interlayer film 13 refers to, for example, foaming, clouding, peeling, or the like of the interlayer film.

[0019] As shown in FIG. 2 , the peripheral member 30a has a U-shaped cross section perpendicular to the longitudinal direction of the peripheral member 30a (the depth direction in the drawing), and is disposed so that the edge 17 of the laminated glass 10 fits into a U-shaped groove 33 of the peripheral member 30a. Specifically, the peripheral member 30a includes a first protrusion 31 protruding from one side of the groove 33 and a second protrusion 32 protruding from the other side. The first protrusion 31 is provided so as to cover the exterior surface 15 of the first glass sheet 11. The second protrusion 32 is provided so as to cover the interior surface 16 of the second glass sheet 12.

[0020] The thickness of the first protrusion 31 is preferably 0.1 mm to 10 mm, more preferably 0.3 mm to 5 mm, and even more preferably 0.5 mm to 3 mm. The thickness of the second protrusion 32 is preferably 0.1 mm to 15 mm, more preferably 0.3 mm to 10 mm, and even more preferably 0.5 mm to 5 mm.

[0021] The peripheral member 30a is made of a metal material or a resin material. When the peripheral member 30a is made of a metal material, stainless steel, iron, steel, aluminum, an aluminum alloy, a titanium alloy, a magnesium alloy, or the like can be used. When the peripheral member 30a is made of a resin material, PC, PBT, PET, PA, POM, ABS, PEEK, PPS, or the like can be used. In this embodiment, the resin material is preferably colored. That is, when a metal material or a colored resin material is used for the peripheral member 30a, irradiation of the interlayer film 13 on the edge 17 side of the laminated glass 10 by sunlight can be suppressed, thereby suppressing deterioration of the interlayer film 13 due to sunlight. The peripheral member 30a may also be made of a fiber-reinforced plastic, such as carbon fiber reinforced plastic (CFRP) or glass fiber reinforced plastic (GFRP).

[0022] For these reasons, for example, the visible light transmittance of the peripheral member 30a is preferably 1% or less. Furthermore, the peripheral member 30a may be disposed on the surface 15 of the first glass plate 11 at a distance of 5 mm or more, preferably 7 mm or more, and more preferably 10 mm or more from the edge 17 of the first glass plate 11, on the inner surface of the first glass plate 11. That is, as shown in Fig. 2 , the first protrusion 31 of the peripheral member 30a is disposed at a distance d from the edge 17 of the first glass plate 11 on the inner surface of the first glass plate 11, and the value of the distance d in this case may be 5 mm or more, preferably 7 mm or more, and more preferably 10 mm or more.

[0023] In consideration of suppressing irradiation of the interlayer film 13 with sunlight, it is effective to set the length (distance d) of the first protrusion 31 located on the vehicle exterior side to 5 mm or more, and the length of the second protrusion 32 located on the vehicle interior side can be determined arbitrarily. In other words, the distance d for the second protrusion 32 may be less than 5 mm.

[0024] Alternatively, for example, the peripheral member 30a may be bonded to the edge 17 of the laminated glass 10 using an adhesive. For example, a urethane adhesive, a modified silicone adhesive, an epoxy adhesive, an acrylic adhesive, or the like may be used as the adhesive. Alternatively, the peripheral member 30a may be molded integrally with the laminated glass 10. For example, an insert molding technique may be used in which the laminated glass 10 and a resin material are integrated by injection molding.

[0025] In this embodiment, a sealing material may be filled between the peripheral member 30a and the vehicle exterior surface 15 of the first glass plate 11. The sealing material may be a urethane adhesive, a modified silicone adhesive, an epoxy adhesive, an acrylic adhesive, or the like. Providing the sealing material can prevent moisture and the like from reaching the interlayer film 13 from the vehicle exterior side through the gap between the first glass plate 11 and the peripheral member 30a.

[0026] As described above, in the vehicle window glass 1 according to this embodiment, the peripheral members 30a, 30b are provided on the front side edge 21 and the rear side edge 22 of the laminated glass 10 so as to cover the edge 17 of the laminated glass 10. By providing the peripheral members 30a, 30b in this manner, it is possible to prevent the interlayer film 13 constituting the laminated glass 10 from being directly exposed to the external environment, thereby preventing deterioration of the interlayer film 13.

[0027] Furthermore, vehicle window glass used in sashless doors does not have a sash (window frame) to support the window glass, and therefore has a problem of reduced support rigidity of the window glass compared to doors with a sash that supports the window glass. In this embodiment, peripheral members 30a, 30b are provided on the front side edge 21 and the rear side edge 22 of the laminated glass 10, thereby increasing the rigidity of the vehicle window glass 1. In this case, the Young's modulus of the peripheral members 30a, 30b is preferably 0.5 GPa or more, more preferably 1.5 GPa or more, even more preferably 5 GPa or more, even more preferably 10 GPa or more, particularly preferably 50 GPa or more, and may be 70 GPa or more, or may be 150 GPa or more. In other words, the higher the Young's modulus of the peripheral members 30a, 30b, the higher the rigidity of the vehicle window glass 1.

[0028] In particular, in this embodiment, as shown in Fig. 1, when the vehicle window glass 1 is viewed in plan, it is preferable that the belt molding 50 of the door panel 80 (see Fig. 11) to which the vehicle window glass 1 is attached intersects with the peripheral members 30a, 30b. In other words, it is preferable that the peripheral members 30a, 30b are arranged so as to straddle the belt molding 50. In Fig. 1, the position corresponding to the belt molding 50 is indicated by a dashed line.

[0029] When the vehicle window glass 1 is attached to the door panel 80, the vehicle window glass 1 is clamped by the belt molding 50. Therefore, when the peripheral members 30a, 30b are arranged so as to straddle the belt molding 50, the peripheral members 30a, 30b are supported by the belt molding 50, and the rigidity of the vehicle window glass 1 is also improved.

[0030] Note that Fig. 1 shows a configuration example in which peripheral members 30a, 30b are provided on both the front and rear side edges 21, 22 of the laminated glass 10. However, in this embodiment, the peripheral members 30a, 30b may be provided on only one of the front side edge 21 and the rear side edge 22 of the laminated glass 10. In other words, in this embodiment, the peripheral members 30a, 30b may be provided on at least one of the front side edge 21 and the rear side edge 22 of the laminated glass 10. Furthermore, while Fig. 2 describes the cross-sectional shape of the peripheral member 30a, the same applies to the other peripheral members 30b, 30c.

[0031] Next, other configuration examples of the vehicle window glass according to this embodiment will be described using Figures 3 to 7. In this embodiment, as in the vehicle window glass 1a shown in Figure 3, peripheral members 30a, 30b, and 30c may be provided on the front side edge 21, rear side edge 22, and top edge 23 of the laminated glass 10, respectively. That is, in the configuration example shown in Figure 3, compared to the configuration example shown in Figure 1, a peripheral member 30c is further provided on the top edge 23 of the laminated glass 10.

[0032] When the vehicle window glass is installed in a vehicle, the upper edge 23 of the laminated glass 10 abuts against a weatherstrip provided on the vehicle when the vehicle window glass is closed. For example, if the upper edge 23 of the laminated glass 10 is covered by a weatherstrip provided on the vehicle, the interlayer film 13 on the upper edge 23 side of the laminated glass 10 is protected by the weatherstrip. However, if the weatherstrip provided on the vehicle does not cover the interlayer film 13 or if the vehicle window glass is open, the interlayer film 13 on the upper edge 23 side of the laminated glass 10 is not sufficiently protected by the weatherstrip. In this embodiment, as in the vehicle window glass 1a shown in FIG. 3 , by further providing a peripheral member 30c on the upper edge 23 of the laminated glass 10, direct exposure of the interlayer film 13 to the external environment can be more effectively prevented. This more effectively prevents deterioration of the interlayer film 13.

[0033] In this embodiment, as in the vehicle window glass 1b shown in FIG. 4 , the thickness of the peripheral member 30a on the first glass sheet 11 side may be thinner than the thickness of the peripheral member 30a on the second glass sheet 12 side. Specifically, the thickness of the first protrusion 31 on the first glass sheet 11 side of the peripheral member 30a may be thinner than the thickness of the second protrusion 32 on the second glass sheet 12 side of the peripheral member 30a. In this way, when the thickness of the first protrusion 31 arranged on the vehicle exterior side is reduced, the distance from the surface 15 of the first glass sheet 11 to the surface of the first protrusion 31 on the vehicle exterior side can be shortened, thereby reducing the step on the vehicle exterior side. Therefore, the air resistance generated by the peripheral member 30a when the vehicle travels can be reduced. In this case, the thickness of the first protrusion 31 is preferably 10 mm or less, more preferably 5 mm or less, and even more preferably 3 mm or less.

[0034] In this embodiment, as in the vehicle window glass 1c shown in Fig. 5, the peripheral member 30a may have an inclined portion 37 whose thickness inclines from the front side to the rear side of the vehicle on the first glass sheet 11 side (vehicle exterior side). In this way, when the inclined portion 37 is provided on the first glass sheet 11 side of the peripheral member 30a, it is possible to reduce the air resistance caused by the peripheral member 30a when the vehicle is traveling.

[0035] 5, the inclined portion 37 of the peripheral member 30a is configured to increase in thickness from the front side to the rear side of the vehicle and then decrease in thickness from the front side to the rear side of the vehicle. Note that in this embodiment, the inclined portion 37 may be configured to include only an inclined portion whose thickness increases from the front side to the rear side of the vehicle, or may be configured to include only an inclined portion whose thickness decreases from the front side to the rear side of the vehicle.

[0036] In this embodiment, as in the vehicle window glass 1d shown in FIG. 6 , the thickness of the first glass sheet 11 may be greater than the thickness of the second glass sheet 12. By making the thickness of the first glass sheet 11 located on the vehicle exterior side greater than the thickness of the second glass sheet 12 located on the vehicle interior side, the strength of the vehicle window glass 1d is improved. Note that reducing the thickness of the second glass sheet 12 may reduce the edge strength of the second glass sheet 12. However, in this embodiment, the peripheral member 30a is provided on the edge 17 side of the vehicle window glass 1d, thereby effectively protecting the edge of the thin second glass sheet 12. The second glass sheet 12 may be chemically strengthened glass.

[0037] In this embodiment, as in the vehicle window glass 1e shown in Fig. 7 , the cross section of the peripheral member 30a perpendicular to the longitudinal direction of the peripheral member 30a (the depth direction in the drawing) may be L-shaped. In this case, the peripheral member 30a is provided so as to cover the surface 15 of the first glass sheet 11 and the edge 17 of the laminated glass 10. In the configuration example shown in Fig. 7 , the interlayer film 13 constituting the laminated glass 10 is also covered by the peripheral member 30a, which prevents the interlayer film 13 from being directly exposed to the external environment. This prevents deterioration of the interlayer film 13.

[0038] 7 , the first protrusion 31 of the peripheral member 30a is arranged on the front surface 15 side of the first glass sheet 11. Because the front surface 15 side of the first glass sheet 11 faces the exterior of the vehicle, arranging the first protrusion 31 on the exterior side more effectively protects the interlayer film 13 from the external environment. Furthermore, when a metal material or a colored resin material is used for the peripheral member 30a, the first protrusion 31 can prevent sunlight from irradiating the interlayer film 13 on the edge 17 side of the laminated glass 10, thereby preventing the interlayer film 13 from being deteriorated by sunlight.

[0039] <Embodiment 2> Next, embodiment 2 will be described. Fig. 8 is a plan view showing an example of the configuration of a vehicle window glass according to embodiment 2. Fig. 9 is a cross-sectional view taken along the cutting line IX-IX in Fig. 8. As shown in Figs. 8 and 9, this embodiment differs from embodiment 1 in that the peripheral member 30c provided on the upper edge 23 of the laminated glass 10 is made of a ferromagnetic material. Other configurations are the same as those of embodiment 1, and therefore a repeated description will be omitted.

[0040] As shown in Figures 8 and 9, a peripheral member 30c made of a ferromagnetic material is provided on the upper edge 23 of the vehicle window glass 2 (laminated glass 10). The ferromagnetic material constituting the peripheral member 30c can be, for example, a metal material containing iron, nickel, cobalt, manganese, or the like. For example, to suppress corrosion of the peripheral member 30c, the periphery of the peripheral member 30c may be coated with a resin material or the like. Alternatively, the peripheral member 30c may be formed by mixing ferromagnetic metal powder with a resin material.

[0041] 9, in this embodiment, an electromagnet 41 is provided at a position on the vehicle (frame 40) that corresponds to the position at which the peripheral member 30c is provided when the vehicle window glass 2 is attached to the vehicle. The electromagnet 41 is configured to operate (i.e., current flows) when the vehicle speed exceeds a predetermined speed, thereby attracting the peripheral member 30c (ferromagnetic material).

[0042] Vehicle window glass used in sashless doors does not have a sash (window frame) to support the window glass. Therefore, when a vehicle is traveling at high speed, a pressure difference occurs between the outside and inside of the vehicle, which can pull the vehicle window glass toward the outside of the vehicle. This force can also cause a gap to form between the vehicle window glass and the vehicle frame.

[0043] The vehicle window glass 2 according to this embodiment is provided with a peripheral member 30c made of a ferromagnetic material on the upper edge 23 of the laminated glass 10. The electromagnet 41 is activated when the vehicle speed exceeds a predetermined speed, and the electromagnet 41 attracts the peripheral member 30c (ferromagnetic material). This configuration makes it possible to prevent a gap from being generated between the vehicle window glass 2 and the frame 40 of the vehicle body, even when a force is generated that pulls the vehicle window glass toward the outside of the vehicle.

[0044] 8 and 9 show examples in which the peripheral member 30c is made of a ferromagnetic material. In this embodiment, the ferromagnetic material may be embedded in the peripheral member 30c, or may be fixed to the surface of the peripheral member 30c on the vehicle interior side.

[0045] In this embodiment, as in the vehicle window glass 2a shown in FIG. 10 , a ferromagnetic material 18 may be provided between the first glass sheet 11 and the second glass sheet 12 at the top edge 23 of the laminated glass 10. In this case, the ferromagnetic material 18 may be provided at the top edge 23 of the laminated glass 10, a peripheral member 30a may be provided at the front side edge 21, and a peripheral member 30b may be provided at the rear side edge 22. In addition to providing the ferromagnetic material 18 at the top edge 23 of the laminated glass 10, a peripheral member 30c may also be provided at the top edge 23 of the laminated glass 10. When providing the ferromagnetic material 18 and the peripheral member 30c at the top edge 23 of the laminated glass 10, it is preferable that the peripheral member 30c be made of a material other than a metal material. In the configuration examples shown in FIGS. 8 to 10 , a ferromagnetic material is provided at the top edge 23 of the laminated glass 10. Ferromagnetic materials may also be provided at the side edges 21 and 22 of the laminated glass.

[0046] <Other Embodiments> Next, other embodiments will be described. Fig. 11 is a plan view showing an example of the configuration of a sashless door, and is a diagram showing an example of a sashless door configured using the vehicle window glass 1 shown in Fig. 1. As shown in Fig. 11, the sashless door 100 according to this embodiment includes the vehicle window glass 1 described above and a door panel 80 to which the vehicle window glass 1 is attached. A belt molding 50 is provided on the upper side of the door panel 80. The belt molding 50 holds the vehicle window glass 1 in a state in which the vehicle window glass 1 can move up and down.

[0047] As shown in FIG. 1 , holders 60_1 and 60_2 for holding the vehicle window glass 1 are attached to the underside of the vehicle window glass 1. The vehicle window glass 1 is held by the holders 60_1 and 60_2, and these holders 60_1 and 60_2 are fixed to an elevator device (not shown) provided inside the door panel 80. The vehicle window glass 1 moves up and down by the driving force of the elevator device (not shown). Note that while FIG. 11 illustrates a right-side front side door as an example of a sashless door, side doors at other positions can also be configured in a similar manner. Furthermore, sashless doors can also be configured for the vehicle window glasses 1a to 1e and 2 in a similar manner.

[0048] Although the structural examples of the vehicle window glass according to the present embodiment have been described above, the structural examples may be combined with each other.

[0049] The present invention has been described above in accordance with the above-mentioned embodiment, but the present invention is not limited to the configuration of the above-mentioned embodiment, and naturally includes various modifications, alterations, and combinations that a person skilled in the art can make within the scope of the invention as defined in the claims of this application.
