Description

Window structure of car sunroof

The present invention relates to a window panel structure of a sunroof of a vehicle that opens and closes an opening of a vehicle roof.

Conventionally, for example, the window structure of an automobile sunroof is known, for example, from Patent Document 1. As shown in Fig. 8, the window panel structure of the sunroof of the automobile includes a window panel 91 made of glass, an inner window panel 92 joined to the window panel 91 via an adhesive 94, and a weather strip 93. The inner window panel 92 has a flange 92a facing the end surface of the window panel 91 at the periphery. The weather strip 93 has a mounting base portion 93a that is in close contact with the flange 92a of the inner window panel 92, a sealing portion 93b that is integrally formed on the outer peripheral side of the mounting base portion 93a, and an inner periphery that is integrally formed on the mounting base portion 93a. A lip-shaped sealing portion 93c on the upper side and an elastically deformable locking lip 93d. Further, the sealing portion 93b is elastically contacted with the inner wall surface of the opening 90, and the lip-shaped sealing portion 93c is pressed against the upper surface of the window plate 91.

The locking lip 93d abuts against the lower surface of the window 91 and holds the end of the window 91 between the lip-shaped sealing portion 93c.

Moreover, the adhesive 94 is mainly composed of, for example, butyl rubber. It also functions as a sealant. The adhesive 94 is applied between the tip end of the blocking member 95 and the locking lip 93d for ensuring the thickness thereof, and is in contact with the tip end of the locking lip 93d. Thereby, penetration of rainwater or the like from the gap between the lower surface of the window plate 91 and the tip end of the locking lip 93d is suppressed.

However, in the window panel structure of the sunroof of the patent document 1, a part of the application range of the adhesive 94 which functions as a sealant is a state in which the sealing is interrupted, and there is a possibility that the above-described rainwater or the like is allowed to permeate. In this case, there is a possibility that rust on the surface of the flange 92a or the like may occur due to rain or the like that has penetrated. In the surface of the inner window panel 92, there is also a coating material for rust-proof coating. However, in this case, in particular, the unevenness of the coating material is likely to occur at the tip end of the flange 92a, so that rust may still occur.

Here, it is required that the state in which the sealing of the adhesive 94 is interrupted is confirmed beforehand, for example, at the stage before shipment.

An object of the present invention is to provide a window panel structure for a sunroof of a vehicle, and it is possible to confirm a state in which the sealing of the adhesive joining the window panel and the inner window panel is interrupted.

A window panel structure for a vehicle sunroof that solves the above-described problem includes a window panel that closes an opening formed in a roof of a vehicle, and a metal member that is disposed below the window panel along an outer peripheral edge portion of the window panel. The inner louver of the structure and the outer peripheral edge portion of the louver are disposed between the outer peripheral edge portion of the louver and the outer peripheral edge portion of the inner louver a seal portion of the seal portion elastically contacting the inner wall surface of the opening, and an adhesive for water-tightly bonding the lower surface of the window panel and the upper surface of the inner window panel in contact with the tip end of the grip portion In the inner louver, a notch is formed at a position of the tip end of the grip portion that the adhesive contacts.

According to this configuration, in the state where the adhesive is applied to the lower surface of the window panel, if the upper surface of the inner window panel is overlapped with the weather strip, the adhesive is applied if the amount of the adhesive applied is appropriate. The lower surface of the window panel and the upper surface of the inner window panel are watertightly joined in a state of being in contact with the tip end of the grip portion. In particular, in the position where the notch is formed, the state of the adhesive can be visually confirmed by the notch. Further, for example, the state in which the seal of the adhesive is interrupted can be confirmed depending on, for example, the state in which the adhesive does not reach the tip end of the grip portion.

In the window panel structure of the above-described automobile sunroof, the notch is preferably disposed at a corner portion of the inner window panel.

Usually, using an automatic applicator, for example, underneath the aforementioned window panel In the case where the adhesive is applied, the sealing of the adhesive is likely to be interrupted by the corner portion of the outer peripheral edge portion of the window panel. This is caused by the fact that the amount of application of the above-mentioned adhesive which is pressed out from the automatic applicator by the centrifugal force is unstable at the corner portion. According to this configuration, the notch is formed in the corner portion of the inner window panel, so that it is possible to improve the state in which the sealing of the adhesive is interrupted.

In the window panel structure of the automobile sunroof, the inner window panel is a pair of side frames that are disposed in the vehicle width direction, and a front frame that connects the front ends of the two side frames in the vehicle width direction, and a rear frame in which the rear ends of the side frames are connected to each other in the vehicle width direction, and the notches are formed in the corner portions of each of the two side frames and the front frame and the rear frame. The gap between the apex is preferred.

According to this configuration, the four-divided structure including the inner louver, the both side frames, the front frame, and the rear frame can be formed, and the corner portions at four places are formed between the tips of those. The gap serves as the aforementioned gap.

In the window panel structure of the above-described automobile sunroof, each of the two side frames, the front frame and the rear frame are overlapped in the up-and-down direction at the connection positions, and the two side frames, the front frame, and the rear frame are In the above-described connection position and in the frame disposed below, that is, the lower frame, a cover portion that covers the lower side of the notch is preferably formed.

According to this configuration, the cover portion is covered by the front cover The deterioration of the appearance can be suppressed by the lower side of the adhesive exposed by the notch.

In the sash structure of the above-described vehicle sunroof, the grip portion is provided with a lip portion that elastically contacts the lower surface of the louver along the outer peripheral edge portion of the louver in a state in which the adhesive is opposed to the surface. Preferably.

According to this configuration, when the lower surface of the window panel and the upper surface of the inner window panel are joined by the adhesive, the adhesive portion can be restrained from being smeared by the lip portion. The gap between the portion and the lower surface of the window panel penetrates.

The present invention has an effect of confirming a state in which the sealing of the adhesive joining the window panel and the inner window panel is interrupted.

Hereinafter, an embodiment of the window panel structure of the sunroof of the automobile will be described.

As shown in Fig. 1, in the vehicle roof 10 of an automobile or the like, an opening 11 having a substantially square shape is formed, and a substantially square-shaped window panel 20 for opening and closing the opening 11 is provided. In the enlarged surface of the vehicle window panel 20, the direction toward the outer peripheral side is referred to as "outer direction", and the direction toward the center side is referred to as "inner direction".

As shown in Fig. 2, the inner wall surface of the opening 11 is a substantially quadrangular cylindrical flange 12 which is formed to extend downward across the entire circumference thereof. On the other hand, the vehicle window panel 20 is a glass window panel 21 having a substantially square plate shape that is fitted to the flange 12 . In addition, the vehicle window panel 20 includes a substantially square frame inner window panel 22 which is formed of a steel plate disposed below the window panel 21 along the outer peripheral edge portion 21a of the window panel 21. The inner window panel 22 is used to connect the window panel 21 (vehicle window panel 20) to a bracket (shown substantially) that functions as an opening and closing function.

In the inner window panel 22, a locking recess 22a is formed substantially across the entire circumference of the outer peripheral edge portion 21a of the window panel 21. The gap with the window panel 21 is enlarged by the locking recess 22a. The inner window panel 22 extends in a direction further outward than the locking concave portion 22a substantially in parallel with the window panel 21, and has its leading end located outward of the front end of the window panel 21.

As shown in Fig. 4, the inner window panel 22 is composed of: in the car a pair of side frames 23 that are disposed in the width direction, and a front frame 24 that connects the front ends of the side frames 23 in the vehicle width direction, and the rear ends of the side frames 23 are connected to each other in the vehicle width direction. The four-part structure of the frame 25. Further, as shown in an enlarged view of Fig. 5(a), the side frame 23 is joined to the front frame 24 by a plurality of spot welds W in a state in which the leading end of the front frame 24 and the front end thereof are overlapped from above. Further, as shown in an enlarged view of Fig. 5(b), the side frame 23 is joined to the rear frame 25 by a plurality of spot welds W in a state in which the leading end of the rear frame 25 is overlapped from the lower end and the rear end thereof.

Further, a gap C1 is formed between the front end of the side frame 23 and the tip end of the front frame 24 at the end portions in the outer direction. Similarly, between the rear end of the side frame 23 and the front end of the rear frame 25, a gap C2 is formed at the end portions of the outer direction. In other words, the inner window panel 22 has a notch 22c that is open in the outward direction in each of the four corner portions 22b of the two side frames 23 and the front frame 24 and the rear frame 25. Each of the notches 22c extends inward in the direction of the locking recess 22a. Therefore, the locking recess 22a is divided by four places by the notch 22c.

As shown in FIG. 2, the vehicle window panel 20 is provided with a weather strip 26 that is attached to the outer peripheral edge portion 21a of the window panel 21. This weather strip 26 is formed annularly at substantially four corners extending across the entire circumference of the window panel 21. The weather strip 26 has a belt-shaped main body portion 26a that surrounds the outer peripheral edge portion 21a of the window panel 21, and has a grip portion 26b extending from the main body portion 26a in the inward direction along the lower surface of the outer peripheral edge portion 21a, and further A covering portion extending inward from the upper surface of the outer peripheral edge portion 21a from the main body portion 26a 26c. The weather strip 26 is attached and fixed to the outer peripheral edge portion 21a in a state in which the outer peripheral edge portion 21a of the window panel 21 is held by the grip portion 26b and the covering portion 26c across the entire circumference thereof. At this time, the grip portion 26b is held between the outer peripheral edge portion 21a of the window panel 21 and the outer peripheral edge portion 22d of the inner window panel 22.

Further, the lower portion of the tip end portion of the grip portion 26b is formed with a locking projection portion 26d having a substantially hook-shaped cross section across the entire circumference thereof. The weather strip 26 is restricted from being moved toward the outer direction of the window panel 21 by fitting the locking projection 26d into the locking recess 22a. On the other hand, the upper portion of the tip end portion of the grip portion 26b is formed with a lip portion 26e that faces the inner circumferential direction across the entire circumferential surface thereof. In the two-point lock line of Fig. 2, the lip portion 26e rises in a state in which the weather strip 26 is single, and elastically contacts the lower surface of the window panel 21 along the outer peripheral edge portion 21a of the window panel 21. In the inner direction of the lip portion 26e, a recess portion 26h for accommodating the lip portion 26e that is pressed against the lower surface of the window plate 21 is formed.

Further, the weather strip 26 has a support piece 26f extending inward from the body portion 26a from below the held portion 26b. The support piece 26f extends over the entire circumference of the main body portion 26a, and holds the outer peripheral edge portion 22d of the inner window panel 22 between the held portion 26b and the held portion 26b. Further, the weather strip 26 is a seal portion 26g having a substantially arc-shaped cross section that is connected to the upper end edge and the lower end edge of the main body portion 26a and protrudes outward. The seal portion 26g extends over the entire circumference of the body portion 26a and elastically contacts the flange 12 facing the vehicle roof 10.

Further, the sealing portion 26g of the weather strip 26 is made of, for example, urethane The resin sponge material is molded, and the other portion (the main body portion 26a or the like) of the weather strip 26 is formed of a hard solid material such as urethane resin. That is, the weather strip 26 is formed of two colors by a sponge material of a urethane resin and a hard solid material of a urethane resin.

The lower surface of the louver 21 and the upper surface of the inner louver 22 are joined by an adhesive 27 interposed between them in the inner direction than the held portion 26b. The adhesive 27 is made of, for example, urethane resin, and the lower surface of the window panel 21 and the upper surface of the inner window panel 22 are watertightly joined in a state of being in contact with the tip end of the grip portion 26b. In other words, when the adhesive 27 is expanded between the lower surface of the window panel 21 and the upper surface of the inner window panel 22 in the applied state, the amount of application is set so as to be in contact with the tip end of the grip portion 26b. In this way, rainwater or the like which has entered the gap between the outer peripheral edge portion 21a of the window panel 21 and the covering portion 26c can be suppressed by the adhesive 27, and the gap between the outer peripheral edge portion 21a and the held portion 26b can be infiltrated inward. The rust of this inner window panel 22 occurs.

Next, the action of this embodiment will be described.

When the lower surface of the window panel 21 and the upper surface of the inner window panel 22 are joined by the adhesive 27, first, an adhesive 27 is applied to the lower surface of the window panel 21 along the outer peripheral edge portion 21a of the window panel 21 by using an automatic applicator. Further, the outer peripheral edge portion 22d of the inner window panel 22 is inserted between the held portion 26b of the weather strip 26 and the support piece 26f, and the weather strip 26 is preliminarily assembled to the inner window panel 22. At this time, the weather strip 26 is positioned in the inner window panel 22 by the locking convex portion 26d being fitted into the locking concave portion 22a of the inner window panel 22.

Next, the inner window panel 22 in a state in which the weather strip 26 is assembled When superimposed on the window panel 21, the adhesive 27 in the applied state is expanded between the lower surface of the window panel 21 and the upper surface of the inner window panel 22. At this time, if the amount of application of the adhesive 27 is appropriate, the adhesive 27 is water-tightly joined to the lower surface of the window panel 21 and the upper surface of the inner window panel 22 while being in contact with the tip end of the held portion 26b. The held portion 26b on which the window panel 21 is placed functions as a spacer for the window panel 21 that is bonded to the inner window panel 22 via the adhesive 27.

Moreover, when the inner window panel 22 is superposed on the window panel 21, the covering portion 26c of the weather strip 26 is pressed by the lower surface of the window panel 21 and is poured along the main body portion 26a. Thereby, the outer peripheral edge portion 21a of the window panel 21 is uniformly urged inward from the covering portion 26c, and the inner window panel 22 and the like are correctly positioned. The covering portion 26c that is poured along the main body portion 26a is pulled back along the upper surface of the window panel 21 using a suitable jig. Thereby, the upper surface of the outer peripheral edge portion 21a of the window panel 21 is covered by the covering portion 26c.

On the other hand, when the inner window panel 22 is overlapped with the window panel 21, the lip portion 26e of the weather strip 26 is elastically brought into contact with it by being pressed down by the lower surface of the window panel 21. Further, the lip portion 26e that elastically contacts the lower surface of the window panel 21 in the state of the adhesive agent 27 in the opposite direction is the adhesive 27 that suppresses the application state of the above-described pressure expansion from the held portion 26b and the window panel 21 The gap below the infiltration.

As shown in Fig. 3, in the position of the notch 22c of the inner window panel 22, the adhesive 27 in the applied state is released, and the adhesive 27 is brought into contact with the tip end of the held portion 26b. A bulging portion 27a that bulges from the notch 22c is formed. This bulging portion 27a is of course fitted to The arrangement of the notches 22c of the inner window panel 22 is formed at four locations. Further, the state of the adhesive 27 interposed between the lower surface of the window panel 21 and the upper surface of the inner window panel 22 can be visually confirmed by the respective notches 22c.

Further, in the state of the notch 22c of the inner window panel 22, the outer peripheral edge portion 21a and the covering portion of the window panel 21 can be similarly suppressed by the adhesive 27 in a state in which the adhesive 27 is in contact with the tip end of the grip portion 26b. The rainwater or the like which has entered the gap of the 26c penetrates inward by the gap between the outer peripheral edge portion 21a and the held portion 26b.

As described in detail above, according to the present embodiment, the effects shown below can be obtained.

(1) In the present embodiment, the state of the adhesive 27 can be visually confirmed by the notch 22c in the formation position of the notch 22c. Further, for example, depending on, for example, the state in which the adhesive 27 does not reach the tip end of the grip portion 26b, the state in which the seal of the adhesive 27 having the function of the sealant is interrupted can be confirmed.

(2) In the case where the adhesive 27 is applied to the lower surface of the window panel 21 by using an automatic applicator, the sealing of the adhesive 27 is likely to be interrupted at the corner portion of the outer peripheral edge portion 21a of the window panel 21. This is caused by the fact that the amount of application is unstable due to the centrifugal force acting on the adhesive 27 pushed out from the automatic applicator at the corner portion. In the present embodiment, by disposing the notch 22c in the corner portion 22b of the inner window panel 22, it is possible to improve the state in which the sealing of the adhesive 27 is interrupted.

(3) In the present embodiment, the inner window panel 22 can be divided into four sections composed of the side frame 23, the front frame 24, and the rear frame 25. The configuration is made, and the corner portions 22b at 4 form the slits C1, C2 formed between the leading ends of those as the slits 22c. Further, since it is not necessary to form the inner window panel 22 from a single steel sheet by punching or the like, the yield can be improved.

(4) In the present embodiment, when the lower surface of the window panel 21 and the upper surface of the inner window panel 22 are joined by the adhesive 27, the adhesive portion 27 in the applied state which is composted between those can be suppressed by the lip portion 26e. Infiltration occurs from the gap between the held portion 26b and the lower surface of the window panel 21.

Further, the above embodiment may be modified as follows. As shown in Fig. 6, the connection position of the front end of the side frame 23 and the front end of the front frame 24 which are vertically overlapped is formed in the side frame 23 which is disposed in the lower frame, that is, the lower frame, and the notch 22c is formed. The cover portion 31 covered underneath may also be used. That is, as shown in Fig. 7, the lid portion 31 extends the end portion of the outer end of the front end of the side frame 23 to the lower end portion reaching the outer end of the front end of the front frame 24. The extension length of the lid portion 31 toward the tip end of the front frame 24 is set so as not to be exposed from the tip end of the lid portion 31 even if the adhesive 27 in the application state is expanded and exposed from the notch 22c. By thus changing the cover portion 31, the underside of the adhesive 27 exposed from the notch 22c is covered, and deterioration in appearance can be suppressed. Further, in this case, the state of the adhesive 27 may be visually confirmed from the outer direction of the inner window panel 22 or the like.

Further, the connection position of the rear end of the side frame 23 and the front end of the rear frame 25 are vertically arranged as a lower frame 25 which is disposed in the lower frame, that is, the lower frame, and the lower portion 22c is formed. The same cover portion (31) covered by the square may also be used.

In the foregoing embodiment, the notch 22c may be provided at at least one of the corner portions 22b of the four inner panel plates 22.

In the foregoing embodiment, a notch in any position other than the corner portion 22b of the inner window panel 22 may be used. That is, the notch of the four-divided structure of the inner window panel 22 may not be used.

In the foregoing embodiment, an individually constructed inner window panel cut out from, for example, one steel plate may be used. Further, the notch may be located at a corner portion of the inner window panel, and may be located at any position other than the corner portion.

In the foregoing embodiment, an inner window panel made of a light metal material such as an aluminum alloy may be used.

In the foregoing embodiment, the weather strip 26 which cuts the lip portion 26e may be used.

In the foregoing embodiment, the window panel 21 may be formed of a synthetic resin (for example, a semi-transparent polycarbonate resin or the like).

In the above-described embodiment, the adhesive 27 may be a synthetic resin other than the urethane resin, which functions as a sealant.

In the foregoing embodiment, the vehicular window panel 20 is fixed to the vehicle roof 10, and the opening 11 cannot be opened or closed.
