Description

[Technical Field]

[0001] The present invention relates to a sealing structure between a window panel and a glass run in a vehicle such as an automobile, which reduces a step between the window panel and a door frame, particularly on the roof side. [Background technology]

[0002] The gap between the window panel and the door frame increases wind resistance and generates wind noise while driving. This gap also detracts from the aesthetic appeal of the roof.

[0003] For example, as shown in FIG. 5, a door window frame structure has been proposed that has a flush surface and is made up of laminated glass with a step structure and glass runs attached to the door frame (for example, Patent Document 1).

[0004] This door window frame structure comprises laminated glass 400 and door frame 300, with glass run 100 provided within door frame 300. Laminated glass 400 comprises outer glass 401 and inner glass 402, with a laminated layer 403 provided between outer glass 401 and inner glass 402, forming a step structure in which the upper end of outer glass 401 is lower than the upper end of inner glass 402. In the embodiment, the thicknesses of outer glass 401 and inner glass 402 are each described as 2 mm, and the thickness of laminated layer 403 is described as 0.76 mm.

[0005] The upper end of the inner glass 402 is inserted into the locking groove of the glass run 100 to ensure sealing. The upper end of the outer glass 401 has an interference fit with the glass run 100. This door window frame structure can reduce the surface difference between the laminated glass 400 and the glass run 100.

[0006] The exterior seal lip 310 of the glass run 100 contacts the upper end of the outer glass 401 and the exterior surface of the inner glass 402 , and its tip contacts the interior surface of the exterior side wall 301 . [Prior art documents] [Patent documents]

[0007] [Patent Document 1] China Utility Model Publication No. 220076106 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in Patent Document 1, the upper end portion of the outer glass 401 is formed in an arc shape, so when a seal lip is used in the glass run that extends downward from the tip of the outer side wall of the vehicle, for example, the tip portion of the seal lip may abut the outer side of the arc shape of the vehicle or the inner side of the arc shape of the vehicle.In particular, if there are parts abutting the outer side of the vehicle and parts abutting the inner side of the vehicle in the longitudinal direction of the vehicle, i.e., the front-to-rear direction, sealing and waterproofing become problematic. [Means for solving the problem]

[0009] The present invention provides a window panel and a seal structure that reduces the step between the door frame on the roof side and the window panel, and also reduces the weight of the window panel when it is made of resin.

[0010] In order to solve the above problem, the present invention of claim 1 is a window panel that is mounted on a vehicle and can be opened and closed in the vertical direction, comprising an interior panel and an exterior panel, wherein the interior upper end of the interior panel has a step structure that is higher than the exterior upper end of the exterior panel, and the exterior panel has an inclined portion whose groove becomes deeper toward the interior of the vehicle.

[0011] According to the present invention of claim 1, the window panel comprises an interior panel and an exterior panel, the interior upper end of the interior panel has a step structure that is higher than the exterior upper end of the exterior panel, and the exterior panel has an inclined portion whose groove deepens toward the interior side, so that even when a seal lip extending downward from the tip of the exterior side wall of the glass run is used, the tip of the seal lip can be guided toward the interior side by the inclined portion. As a result, it is possible to prevent a portion abutting the exterior side and a portion abutting the interior side from appearing in the longitudinal direction of the vehicle, and it is possible to reduce the step between the door frame on the roof side and the window panel.

[0012] The present invention of claim 2 is a window panel that is mounted on a vehicle and can be opened and closed in the vertical direction, characterized in that it comprises a window panel main body, a protrusion that protrudes from the interior side of the vehicle and from below the upper end of the panel main body of the window panel main body toward the interior side of the vehicle, and an interior side member that has a substantially L-shaped cross section and is connected to the protrusion and extends above the upper end of the panel main body.

[0013] In the present invention of claim 2, the window panel comprises an interior-facing member having a generally L-shaped cross section, the interior-facing member comprising a protruding portion that protrudes from below the upper end of the panel body of the window panel body toward the interior of the vehicle, and an extension portion that is connected to the protruding portion and extends above the upper end of the panel body. This makes it possible to reduce the weight of the window panel compared to when panels are stacked and a step shape is formed at the upper end portion.

[0014] Furthermore, even when a seal lip extending downward from the tip of the exterior side wall of the glass run is used, the tip of the seal lip can be guided between the upper end of the window panel main body and the interior member, preventing portions from abutting the exterior side and portions from abutting the interior side in the longitudinal direction of the vehicle, and reducing the step between the door frame on the roof side and the window panel.

[0015] The present invention of claim 3 is the window panel of claim 2, wherein the extension portion is inclined toward the vehicle exterior.

[0016] In the present invention of claim 3, since the extension portion is inclined toward the vehicle exterior, for example, in the case of a glass run, when an interior seal lip extending upward from the tip portion of the interior side wall elastically contacts the interior surface of the extension portion, the degree of deflection of the interior seal lip is reduced when the window panel is closed, thereby improving the durability of the glass run.

[0017] The present invention of claim 4 is the window panel of claim 3, wherein a vertical surface that is approximately parallel to the interior surface of the window panel main body is formed on the exterior side of the vehicle of the extended portion.

[0018] In the present invention of claim 4, a vertical surface that is approximately parallel to the interior surface of the window panel main body is formed on the exterior side of the extension, so that when the tip of the extension abuts on the interior surface of the exterior side wall of the glass run, it is possible to prevent damage to the abutting portion.

[0019] The present invention of claim 5 is the window panel of claim 2 or claim 3, wherein the protruding portion is formed thicker on the window panel main body side.

[0020] In the present invention of claim 5, the protrusion is formed thicker on the window panel main body side, which increases the strength of connection with the window panel main body, thereby improving the durability of the window panel.

[0021] The present invention of claim 6 is the invention of claim 1 or claim 2, wherein the window panel is made of resin. In the present invention of claim 6, since the window panel is made of resin, the window panel can be made lighter. In addition, the window panel has excellent workability.

[0022] The present invention of claim 7 provides a seal structure in which a door frame of a vehicle is fitted with a glass run including a bottom wall, an interior side wall and an exterior side wall extending from the bottom wall, an interior seal lip connected to the interior side wall and extending toward the exterior side of the vehicle and the bottom wall side, and an exterior seal lip connected to the exterior side wall and extending toward the interior side and the opposite side to the bottom wall side, and an openable / closable window panel is inserted between the interior seal lip and the exterior seal lip, the window panel including an interior panel and an exterior panel, the interior upper end of the interior panel having a step structure that is higher than the exterior upper end of the exterior panel, and the exterior upper end having an inclined portion whose groove deepens toward the interior of the vehicle, and the inclined portion and the exterior seal lip come into contact when the window panel is closed.

[0023] According to the seventh aspect of the present invention, the interior upper end of the interior panel has a step structure that is higher than the exterior upper end of the exterior panel, and the exterior upper end has an inclined portion that deepens toward the interior side. When the window panel is closed, the inclined portion abuts against the exterior seal lip, so that the leading edge of the exterior seal lip can be guided toward the interior side by the inclined portion, preventing a portion abutting the exterior side and a portion abutting the interior side in the longitudinal direction of the vehicle. Furthermore, the abutment of the inclined portion against the exterior seal lip ensures sealing and waterproofing. Furthermore, the step between the door frame on the roof side and the window panel can be reduced. Therefore, wind resistance during driving can be reduced, and wind noise can be reduced, and the design of the roof portion can be improved by reducing the step.

[0024] The present invention of claim 8 provides a seal structure in which a door frame of a vehicle is fitted with a glass run including a bottom wall, an interior side wall and an exterior side wall extending from the bottom wall, an interior seal lip connected to the interior side wall and extending toward the exterior of the vehicle and towards the bottom wall, and an exterior seal lip connected to the exterior side wall and extending toward the interior side and opposite the bottom wall, and an openable / closable window panel is inserted between the interior seal lip and the exterior seal lip, wherein the window panel includes a window panel main body, and an interior-side member having a substantially L-shaped cross section, the window panel including: a protruding portion protruding toward the interior of the vehicle from below an upper end of the panel main body of the window panel main body toward the interior of the vehicle, and an extending portion connected to the protruding portion and extending above the upper end of the panel main body, and the exterior seal lip is inserted between the window panel main body and the interior-side member and abuts against it when the window panel is closed.

[0025] In the present invention of claim 8, the window panel comprises a window panel main body, and an interior-side member connected to the interior side of the window panel main body, and the interior-side member has a substantially L-shaped cross section that comprises a protruding portion that protrudes from below the upper end of the panel main body of the window panel main body toward the interior of the vehicle, and an extending portion that is connected to the protruding portion and extends above the upper end of the panel main body, so the window panel can be made lighter in weight compared to when panels are stacked and a step shape is formed at the upper end portions.

[0026] Furthermore, when the window panel is closed, the exterior seal lip is inserted between the window panel main body and the interior member and abuts against it, preventing portions abutting on the exterior side and portions abutting on the interior side in the longitudinal direction of the vehicle. Furthermore, the abutment of the exterior seal lip with the upper end of the panel main body of the window panel main body ensures sealing and waterproofing. Furthermore, the step between the door frame on the roof side and the window panel can be reduced. Therefore, wind resistance during driving can be reduced, and wind noise can be reduced, and the design of the roof portion can be improved by reducing the step.

[0027] The present invention of claim 9 is a seal structure according to the invention of claim 8, wherein the extension portion is inclined toward the vehicle exterior side, and the interior seal lip abuts against the interior surface of the extension portion.

[0028] In the present invention of claim 9, the extension portion is inclined toward the vehicle exterior, and the interior seal lip abuts against the interior surface of the extension portion, so that when the window panel is closed, the degree of deflection of the interior seal lip is reduced compared to when the extension portion is not inclined toward the vehicle exterior, thereby improving the durability of the glass run.

[0029] The present invention of claim 10 is the present invention of claim 9, wherein a vertical surface that is approximately parallel to the interior side surface of the window panel main body portion is formed on the exterior side of the extension portion, and the vertical surface has a sealing structure that abuts against the interior side surface of the exterior side wall of the vehicle.

[0030] In the present invention of claim 10, a vertical surface that is approximately parallel to the interior side of the window panel main body is formed on the exterior side of the extension, and the vertical surface abuts against the interior side of the exterior side wall of the vehicle, thereby preventing damage to the abutting portion.

[0031] Furthermore, since the vertical surface abuts against the interior surface of the exterior side wall, sealing and waterproofing are improved, and the shielding effect against transmitted sound along the glass run transmission route, which penetrates between the exterior seal lip and the window panel, goes around the window panel, and enters the interior of the vehicle, can be improved.

[0032] The present invention of claim 11 is a seal structure in which the window panel is made of resin in the invention of claim 7 or claim 8. In the present invention of claim 11, since the window panel is made of resin, the window panel can be made lighter in weight. In addition, the window panel has excellent workability.

[Figure 3] 2 is a cross-sectional view taken along line AA in FIG. 1 showing the seal structure of the first embodiment of the present invention. FIG. [Figure 4] 2 is a cross-sectional view taken along line AA in FIG. 1 showing a seal structure according to a second embodiment of the present invention. FIG. [Figure 5] This is a conventional door window frame structure (Patent Document 1). DETAILED DESCRIPTION OF THE INVENTION

[0035] A first embodiment of the present invention will be described with reference to Figs. 1 to 3. Fig. 1 is a front view of a left front door 1 of an automobile as seen from outside the vehicle. A door frame 3 is attached to the upper part of a door body 2 that constitutes the front door 1. A window opening is formed by the door frame 3 and the upper edge of the door body 2. A glass run 10 is attached to a door frame groove 5 formed in the door frame 3 and inside the door body 2 to guide the raising and lowering movement of a window panel 4. The present invention is applicable not only to the left front door 1, but also to a right front door and left and right rear doors. It is also applicable to sliding doors with raising and lowering window panels.

[0036] 2 is a simplified front view of only the glass run 10 as seen from the vehicle exterior. The glass run 10 is composed of a first extrusion 11 corresponding to the horizontal frame portion of the door frame 3, a second extrusion 12 corresponding to the front vertical frame portion of the front door 1, and a third extrusion 13 corresponding to the rear vertical frame portion. The front end of the first extrusion 11 is connected to the upper end of the second extrusion 12 by a first molded portion 14. The rear end of the first extrusion 11 is connected to the upper end of the third extrusion 13 by a second molded portion 15.

[0037] 3 is a cross-sectional view taken along the line AA in FIG. 1, showing the glass run 10 attached to the door frame groove 5 of the door frame 3 with the window panel 4 closed. The glass run 10 has a basic framework including a bottom wall 20, an exterior side wall 30, and an interior side wall 40. The interior side wall 40 is larger than the exterior side wall 30, and the glass run 10 has an asymmetrical shape with the interior side being larger.

[0038] The vehicle also includes an interior seal lip 41 connected to the interior side wall 40 and extending to the exterior side of the vehicle and the bottom wall 20 side, and an exterior seal lip 31 connected to the exterior side wall 30 and extending to the interior side of the vehicle and the opposite side to the bottom wall 20 side.

[0039] An exterior groove 21 is formed at the connecting portion between the bottom wall 20 and the exterior side wall 30, and the bottom wall 20 and exterior side wall 30 are connectable in an expandable manner by the exterior groove 21. In addition, a bottom wall seal lip 22 is formed on the window panel 4 side of the bottom wall 20.

[0040] A first exterior-side retaining rib 32 is formed on the exterior side of the exterior side wall 30 near the joint with the bottom wall 20. A second exterior-side retaining rib 33 is formed on the exterior side of the tip portion of the exterior side wall 30. When the glass run 10 is attached to the door frame groove 5, the first exterior-side retaining rib 32 abuts against the door frame groove 5, and the second exterior-side retaining rib 33 abuts against the lower part of the tip portion of the bent door frame groove 5.

[0041] The outer-vehicle side wall 30 is formed so that its thickness is thinner toward its tip end, and the tip end is bent toward the exterior of the vehicle. An outer-vehicle seal lip 31 is formed at the tip end of the outer-vehicle side wall 30, facing the interior of the vehicle and extending opposite the bottom wall 20. The outer-vehicle seal lip 31 is formed in an arc shape that convex downward and toward the exterior of the vehicle, and its tip end is located more inboard than the joint with the outer-vehicle side wall 30.

[0042] The interior side wall 40 includes a first interior side wall portion 42, a second interior side wall portion 43, and a side wall connecting portion 44 that connects the first interior side wall portion 42 and the second interior side wall portion 43. The second interior side wall portion 43 is located on the exterior side of the vehicle with respect to the first interior side wall portion 42.

[0043] A first interior retaining lip 45 is formed on the interior side of the connecting portion between the first interior side wall portion 42 and the bottom wall 20, extending toward the interior side and in a direction away from the bottom wall 20.

[0044] A side wall protrusion 47 is formed so as to extend substantially perpendicularly from the interior side of the second interior side wall portion 43, with its tip portion bent downward. Also, a second interior retaining lip 46 is provided so as to extend upward from the tip portion of the side wall protrusion 47 toward the interior side of the vehicle.

[0045] When the glass run 10 is attached to the door frame groove 5, the first interior support lip 45 and the second interior support lip 46 abut against the door frame groove 5, and the side wall protrusion 47 abuts against the hemmed portion of the door frame groove 5. In addition, a trim 70 is inserted between the hemmed portion of the door frame groove 5 and the interior surface of the second interior side wall portion 43.

[0046] The interior seal lip 41 is formed so as to extend from the tip end portion of the second interior side wall portion 43 toward the exterior side of the vehicle, toward the bottom wall 20, in an arc shape that is convex toward the exterior side of the vehicle.

[0047] In the embodiment of the present invention, the glass run 10 may be made of a material such as rubber, thermoplastic elastomer, or soft synthetic resin. In the case of rubber, EPDM (ethylene propylene diene rubber) is preferable, and in the case of thermoplastic elastomer, olefin-based thermoplastic elastomer (TPO) or dynamically crosslinked thermoplastic elastomer (TPV) are preferable from the viewpoints of weather resistance, recyclability, cost, etc.

[0048] The window panel 4 is made up of an interior panel 50, an exterior panel 51, and an adhesive layer 52 between the interior panel 50 and the exterior panel 51. The window panel 4 is made of resin, and polycarbonate is used for the interior panel 50 and the exterior panel 51. In addition to polycarbonate, polymethyl methacrylate, polyethylene terephthalate, polyvinyl chloride, epoxy resin, etc. can also be used.

[0049] The thickness of the interior panel 50 and the exterior panel 51 is about 2 mm, and the thickness of the adhesive layer 52 is about 0.8 mm.

[0050] The window panel 4 has a stepped structure in which the interior upper end 54 of the interior panel 50 is located above the exterior upper end 53 of the exterior panel 51. In addition, the exterior upper end 53 is formed with an inclined portion 55 in which the groove deepens in a substantially linear manner toward the interior panel 50. In addition, the interior upper end 54 of the interior panel 50 is formed in an arc shape.

[0051] 3, when the window panel 4 is closed, the interior upper end 54 of the interior panel 50 abuts against the bottom wall seal lip 22. In addition, the exterior seal lip 31 is inserted into the interior panel 50 and the inclined portion 55, and the exterior surface of the exterior seal lip 31 abuts against the inclined portion 55.

[0052] Next, a second embodiment of the present invention will be described with reference to Fig. 4. Fig. 4 is a cross-sectional view taken along line AA in Fig. 1, in which the glass run 10 is attached to the door frame groove 5 of the door frame 3 and the window panel 4 is closed.

[0053] The difference between this second embodiment and the above-described first embodiment is that in this second embodiment, the window panel 4 comprises a window panel main body 56, a protrusion 59 that protrudes from the interior side of the vehicle of the window panel main body 56 and from below the panel main body upper end 57 of the window panel main body 56 toward the interior side of the vehicle, and an interior side member 58 having a generally L-shaped cross section that is connected to the protrusion 59 and has an extension 60 that extends above the panel main body upper end 57 of the window panel main body 56.

[0054] In the second embodiment, the window panel main body 56 is made of polycarbonate, the interior member 58 is made of PBT / GF30 (polybutylene terephthalate glass fiber 30%), and a urethane adhesive is used to bond the window panel main body 56. Note that double-sided tape may also be used to bond the window panel main body 56 and the interior member 58. The material of the interior member 58 is not limited to PBT / GF30.

[0055] The thickness of the window panel main body 56 is approximately 4 mm, the thickness of the extension portion 60 is 3 mm, and the distance between the window panel main body 56 and the extension portion 60 at the protrusion 59 is approximately 1 mm at the connection portion with the window panel main body 56. The panel main body upper end portion 57 of the window panel main body 56 is formed in an arc shape.

[0056] The protruding portion 59 is formed thicker on the window panel main body 56 side. The extension portion 60 is inclined toward the exterior of the vehicle, and at its tip portion is formed a vertical surface 61 that is approximately parallel to the interior surface of the window panel main body 56. The interior side of the connecting portion between the protruding portion 59 and the extension portion 60 and the tip portion above the vertical surface 61 are chamfered for safety.

[0057] As shown in Figure 4, when the window panel 4 is closed, the panel body upper end portion 57 of the window panel body portion 56 abuts against the exterior seal lip 31. Furthermore, when the window panel 4 is closed, the exterior seal lip 31 abuts against the panel body upper end portion 57, and then moves toward the interior member 58, and also deforms so that its base portion moves slightly toward the exterior side of the vehicle.

[0058] The extension portion 60 is inclined toward the vehicle exterior, and the interior seal lip 41 abuts against an interior side surface 62 of the extension portion 60 .

[0059] The vertical surface 61 abuts against the interior surface 34 of the exterior side wall 30 .

[0060] As described above in detail, according to this embodiment, the following effects can be obtained. (1) In the first embodiment, the window panel 4 is made of resin, which allows the window panel to be lightweight.

[0061] (2) Furthermore, the interior upper end 54 of the window panel 4 has a stepped structure that is higher than the exterior upper end 53, and the exterior upper end 53 has an inclined portion 55 that deepens toward the interior. This allows the leading edge of the exterior seal lip 31 to be guided toward the interior when the window panel 4 is closed, preventing a portion abutting the exterior side and a portion abutting the interior side in the longitudinal direction of the vehicle. Furthermore, since the inclined portion 55 abuts against the exterior seal lip 31, sealing and waterproofing properties can be ensured. Furthermore, the step between the door frame 3 on the roof side and the window panel 4 can be reduced. Therefore, wind resistance during driving can be reduced, and wind noise can be reduced, and the design of the roof portion can be improved by reducing the step.

[0062] (3) The second embodiment includes a window panel main body 56 and an interior-side member 58 connected to the interior side of the window panel main body 56. The interior-side member 58 has a generally L-shaped cross section including a protruding portion 59 that protrudes from below the panel main body upper end portion 57 of the window panel main body 56 toward the interior side of the vehicle, and an extending portion 60 that is connected to the protruding portion 59 and extends above the panel main body upper end portion 57. Therefore, the window panel 4 can be made lighter than in the first embodiment described above, in which panels are stacked and a step shape is formed at the upper end portion thereof.

[0063] (4) When the window panel 4 is closed, the exterior seal lip 31 abuts against the upper end 57 of the panel body and then moves toward the interior member 58, and the base portion deforms so as to move slightly toward the exterior of the vehicle, thereby reducing the step between the door frame 3 on the roof side and the window panel 4. Therefore, wind resistance during driving can be reduced, and wind noise can be reduced, and the design of the roof portion can be improved by reducing the step.

[0064] (5) Furthermore, since the extension portion 60 is inclined toward the vehicle exterior and the interior seal lip 41 abuts against the interior side surface 62 of the extension portion 60, the degree of deflection of the interior seal lip 41 is reduced when the window panel 4 is closed compared to when the extension portion 60 is not inclined toward the vehicle exterior. As a result, the durability of the glass run is improved.

[0065] (6) Furthermore, a vertical surface 61 that is approximately parallel to the interior side surface of the window panel main body 56 is formed on the exterior side of the extension portion 60, and the vertical surface 61 abuts against the interior side surface 34 of the exterior side wall 30, thereby preventing damage to the abutting portion. Furthermore, since the vertical surface 61 abuts against the interior surface 34 of the exterior side wall 30, sealing and waterproofing properties are improved. In addition, the effect of blocking transmitted sound along the glass run transmission route, which penetrates between the vehicle exterior seal lip 31 and the window panel 4, goes around the window panel 4 and penetrates into the vehicle interior, can be improved.

[0066] (7) Furthermore, since the protrusion 59 is formed thicker on the window panel main body 56 side, it is possible to increase the connection strength with the window panel main body 56. As a result, it is possible to improve the durability of the window panel 4.

[0067] In addition to the aspects set forth in the claims, the present invention also includes the following aspects. 5. The window panel according to claim 4, wherein the protrusion is formed to be thicker on the window panel main body side.

[0068] 6. The window panel according to claim 3, wherein the window panel is made of resin.

[0069] 11. The sealing structure according to claim 9 or 10, wherein the window panel is made of resin.

[0070] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the object of the present invention.

[0071] For example, in the second embodiment described above, the extension portion 60 is formed so as to be inclined toward the vehicle exterior, but the extension portion 60 may be formed so as to be substantially parallel to the window panel main body portion 56. In this case, when the window panel 4 is closed, the tip portion of the extension portion 60 abuts against the bottom wall seal lip 22.

[0072] For example, in the second embodiment described above, the panel body upper end portion 57 of the window panel body portion 56 is formed in an arc shape, but the inboard side may be formed with a substantially linear inclined portion 55, as in the exterior-side panel 51 of the first embodiment described above. Forming the inclined portion 55 makes it easier to insert the exterior-side seal lip 31 between the panel body upper end portion 57 and the interior-side member 58. Furthermore, since deflection of the exterior-side seal lip 31 can be reduced even after it abuts against the panel body upper end portion 57, the durability of the exterior-side seal lip 31 can be improved.

[0073] For example, in the above embodiment, the interior side wall 40 is formed in a stepped shape having a first interior side wall portion 42, a second interior side wall portion 43, and a side wall connecting portion 44 that connects the first interior side wall portion 42 and the second interior side wall portion 43.This is done in consideration of the shape of the door frame groove portion 5 and the reception position of the tip of the trim 70, and if the shape of the door frame groove portion 5 and the reception position of the tip of the trim 70 are changed, it is also possible to use, for example, an interior side wall that is approximately linear in shape.
