Description

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

  Conventionally, as a panel structure of such a sunroof, what was described in patent document 1, for example is known. As shown in FIG. 8, the sunroof panel structure includes a glass panel 91, an inner panel 92 joined to the panel 91 via an adhesive 94, and a weather strip 93. The inner panel 92 has a flange 92 a at the periphery that faces the end surface of the panel 91. The weather strip 93 is integrated with an attachment base portion 93a that is in close contact with the flange 92a of the inner panel 92, a seal portion 93b that is integrally formed on the outer peripheral side surface of the attachment base portion 93a, and an upper portion on the inner peripheral side of the attachment base portion 93a. It has a formed lip-shaped seal portion 93c and an elastically deformable locking lip 93d. The seal portion 93 b is in elastic contact with the inner wall surface of the opening 90, and the lip-shaped seal portion 93 c is in pressure contact with the upper surface of the panel 91. The locking lip 93d is in contact with the lower surface of the panel 91 and holds the end portion of the panel 91 with the lip-shaped seal portion 93c.

  Note that the adhesive 94 has, for example, butyl rubber as a main component, and also has a function as a sealer. The adhesive 94 is applied between the dam member 95 for securing the thickness and the tip of the locking lip 93d, and is in contact with the tip of the locking lip 93d. Thereby, intrusion of rainwater or the like from the gap between the lower surface of the panel 91 and the tip of the locking lip 93d is suppressed.

JP-A-8-58392

  By the way, in the sunroof panel structure of Patent Document 1, when a part of the application range of the adhesive 94 that also functions as a sealer is in a state of being out of seal, there is a possibility that intrusion of the rainwater or the like described above may be permitted. . In this case, rust may be generated on the surface of the flange 92a or the like due to infiltrated rainwater or the like. A coating material for rust prevention may be painted on the surface of the inner panel 92, but even in that case, the coating material is likely to be uneven, particularly at the tip of the flange 92a, and rust is still generated. there is a possibility.

Therefore, it is required to check the state of the seal of the adhesive 94 in advance, for example, at a stage before shipment.
The objective of this invention is providing the panel structure of the sunroof which can confirm the state of the seal | sticker cut | disconnection of the adhesive agent which joins a panel and an inner panel.

A panel structure of a sunroof that solves the above problems includes a panel that closes an opening formed in a vehicle roof, an inner panel made of a metal material disposed below the panel along an outer peripheral edge of the panel, It is attached to the panel along the outer peripheral edge of the panel, and can be elastically contacted with the sandwiched portion sandwiched between the outer peripheral edge of the panel and the outer peripheral edge of the inner panel, and the inner wall surface of the opening. A weather strip having a seal portion; and an adhesive for watertightly bonding the lower surface of the panel and the upper surface of the inner panel in contact with the tip of the sandwiched portion; agent is formed notch in the position of the tip of the clamped portion in contact, the notch is arranged at a corner portion of the inner panel, the inner panel, A pair of side frames arranged side by side in both width directions, a front frame connecting front ends of the side frames in the vehicle width direction, and a rear frame connecting rear ends of the side frames in the vehicle width direction; The notch is a gap formed between the front ends of the four corner portions where each of the side frames is connected to the front frame and the rear frame .

  According to this configuration, for example, when the upper surface of the inner panel is overlapped with the weather strip in a state where the adhesive is applied to the lower surface of the panel, the adhesive is applied if the amount of the adhesive applied is appropriate. Are watertightly joined to the lower surface of the panel and the upper surface of the inner panel in contact with the tip of the sandwiched portion. In particular, at the formation position of the notch, the state of the adhesive can be visually confirmed through the notch. For example, the state of the adhesive being out of seal can be confirmed based on the state where the adhesive does not reach the tip of the sandwiched portion.

Normally, using an automatic coating machine, for example in the case of applying the adhesive to the lower surface of the panel, the state of seal breakage is likely to occur of the adhesive in the corner portions of the outer peripheral edge of the panel. This is because the application amount becomes unstable due to the centrifugal force acting on the adhesive pushed out from the automatic coating machine at the corner. According to this configuration, since the notch is disposed at the corner portion of the inner panel, it is possible to increase a possibility that the state of the adhesive being out of seal can be found.

  According to this configuration, the inner panel has a four-divided structure including the both side frames, the front frame, and the rear frame, and the gaps formed between the tips of the four corner portions are formed as the gaps. Can be a notch.

  With regard to the panel structure of the sunroof, each of the side frames, the front frame and the rear frame are overlapped in the vertical direction at their connection positions, and the both side frames, the front frame and the rear frame are overlapped. Among these, it is preferable that a cover portion that covers a lower portion of the notch is formed on a lower frame that is a frame disposed below in the connection position.

According to this configuration, the lower part of the adhesive exposed from the notch is covered by the cover portion, so that deterioration in appearance can be suppressed.
In the sunroof panel structure, the sandwiched portion is preferably provided with a lip portion that elastically contacts the lower surface of the panel along the outer peripheral edge portion of the panel in a state of facing the adhesive.

  According to this configuration, when the lower surface of the panel and the upper surface of the inner panel are bonded with the adhesive, the adhesive in an applied state that is spread between them is formed between the sandwiched portion and the lower surface of the panel. Intrusion from the gap can be suppressed by the lip portion.

As shown in FIG. 1, a substantially rectangular opening 11 is formed in a vehicle roof 10 of an automobile or the like, and a substantially rectangular vehicle panel 20 that can open and close the opening 11 is installed. In the following, on the surface where the vehicle panel 20 spreads, the direction toward the outer peripheral side is referred to as “outward direction”, and the direction toward the center side is referred to as “inward direction”.

  As shown in FIG. 2, the inner wall surface of the opening 11 forms a substantially square cylindrical flange 12 that extends downward over the entire circumference. On the other hand, the vehicle panel 20 includes a substantially square plate-like glass panel 21 formed in accordance with the flange 12. The vehicle panel 20 includes a substantially rectangular frame-shaped inner panel 22 made of a steel plate disposed below the panel 21 along the outer peripheral edge 21 a of the panel 21. The inner panel 22 is for connecting the panel 21 (vehicle panel 20) to a function bracket (not shown) related to the opening / closing operation thereof.

  The inner panel 22 is formed with a locking recess 22a over substantially the entire circumference below the outer peripheral edge 21a of the panel 21. A gap with the panel 21 is widened by the locking recess 22a. The inner panel 22 has an outer portion extending substantially parallel to the panel 21 than the locking recess 22 a, and a distal end of the inner panel 22 is positioned outward from the distal end of the panel 21.

  As shown in FIG. 4, the inner panel 22 includes a pair of side frames 23 arranged side by side in the vehicle width direction, a front frame 24 that connects the front ends of both side frames 23 in the vehicle width direction, and both side frames 23. A rear frame 25 that connects rear ends of the rear ends in the vehicle width direction is provided. As shown in an enlarged view in FIG. 5A, the side frame 23 is joined to the front frame 24 by spot welding W at a plurality of locations in a state where the front frame 24 is overlapped with the front end from above. ing. Further, as shown in an enlarged view in FIG. 5B, the side frame 23 is joined to the rear frame 25 by spot welding W at a plurality of locations in a state where the front end of the rear frame 25 is superimposed on the rear end from below. ing.

  A gap C <b> 1 is formed between the front end of the side frame 23 and the front end of the front frame 24 at the outer end thereof. Similarly, a gap C <b> 2 is formed between the rear end of the side frame 23 and the front end of the rear frame 25 at the outer ends thereof. That is, the inner panel 22 forms notches 22c that open outwardly at the four corner portions 22b where the side frames 23 are connected to the front frame 24 and the rear frame 25, respectively. Each notch 22c extends inward until it passes through the locking recess 22a. Therefore, the locking recess 22a is divided at four locations by the notch 22c.

  As shown in FIG. 2, the vehicle panel 20 includes a weather strip 26 attached to the outer peripheral edge 21 a of the panel 21. The weather strip 26 is formed in a substantially square annular shape extending over the entire circumference of the panel 21. The weather strip 26 has a band-shaped main body portion 26a surrounding the outer peripheral edge portion 21a of the panel 21, and a sandwiched portion 26b extending inward along the lower surface of the outer peripheral edge portion 21a from the main body portion 26a. And a covering portion 26c extending inward from the main body portion 26a along the upper surface of the outer peripheral edge portion 21a. The weather strip 26 is mounted and fixed to the outer peripheral edge portion 21a in a state where the outer peripheral edge portion 21a of the panel 21 is held by the sandwiched portion 26b and the covering portion 26c over the entire circumference. At this time, the sandwiched portion 26 b is sandwiched between the outer peripheral edge portion 21 a of the panel 21 and the outer peripheral edge portion 22 d of the inner panel 22.

  Note that the lower end of the tip of the sandwiched portion 26b forms a locking projection 26d having a substantially claw-shaped cross section over the entire circumference. The weather strip 26 is restricted from moving outward with respect to the panel 21 by the engaging protrusions 26d fitting into the engaging recesses 22a. On the other hand, the upper end portion of the sandwiched portion 26b forms a lip portion 26e that faces inward over the entire circumference. As depicted by a two-dot chain line in FIG. 2, the lip portion 26 e stands up in the state of the weather strip 26 alone, and is elastically formed on the lower surface of the panel 21 along the outer peripheral edge portion 21 a of the panel 21. To touch. In the inward direction of the lip portion 26e, a concave portion 26h is formed for accommodating the lip portion 26e that is pushed down and falls down on the lower surface of the panel 21.

  Further, the weather strip 26 has a support piece 26f that extends inward from the main body 26a below the sandwiched portion 26b. The support piece 26f extends over the entire circumference of the main body portion 26a, and sandwiches the outer peripheral edge portion 22d of the inner panel 22 with the sandwiched portion 26b. Further, the weather strip 26 includes 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 main body portion 26a and elastically contacts the flange 12 facing the vehicle roof 10.

  Note that the seal portion 26g of the weather strip 26 is formed of, for example, a urethane resin sponge material, and other portions (main body portion 26a, etc.) of the weather strip 26 are formed of, for example, a solid material of urethane resin. Molded. That is, the weather strip 26 is molded in two colors by a urethane resin sponge material and a urethane resin solid material.

  The lower surface of the panel 21 and the upper surface of the inner panel 22 are joined to each other by an adhesive 27 interposed between them inwardly of the sandwiched portion 26b. This adhesive 27 is made of, for example, urethane resin, and watertightly joins the lower surface of the panel 21 and the upper surface of the inner panel 22 in a state of being in contact with the tip of the sandwiched portion 26b. In other words, the application amount of the adhesive 27 is set so that the adhesive 27 comes into contact with the tip of the sandwiched portion 26b when being spread between the lower surface of the panel 21 and the upper surface of the inner panel 22 in the application state. ing. As a result, the adhesive 27 prevents rainwater or the like entering from the gap between the outer peripheral edge portion 21a and the covering portion 26c of the panel 21 from entering the inner direction through the gap between the outer peripheral edge portion 21a and the sandwiched portion 26b. Accordingly, the occurrence of rust on the inner panel 22 can be suppressed.

Next, the operation of this embodiment will be described.
When joining the lower surface of the panel 21 and the upper surface of the inner panel 22 with the adhesive 27, first, the adhesive 27 is applied to the lower surface along the outer peripheral edge 21a of the panel 21 using an automatic coating machine. To do. Further, the outer peripheral edge portion 22d of the inner panel 22 is sandwiched between the sandwiched portion 26b and the support piece 26f of the weather strip 26, and the weather strip 26 is assembled to the inner panel 22 in advance. At this time, the weather strip 26 is positioned with respect to the inner panel 22 by the engagement protrusions 26d fitting into the engagement recesses 22a of the inner panel 22.

  Subsequently, when the inner panel 22 with the weather strip 26 assembled is overlaid on the panel 21, the adhesive 27 in the applied state is spread between the lower surface of the panel 21 and the upper surface of the inner panel 22. At this time, if the application amount of the adhesive 27 is appropriate, the adhesive 27 watertightly joins the lower surface of the panel 21 and the upper surface of the inner panel 22 in contact with the tip of the sandwiched portion 26b. The sandwiched portion 26 b on which the panel 21 is placed functions as a spacer of the panel 21 that is joined to the inner panel 22 via the adhesive 27.

  When the inner panel 22 is stacked on the panel 21, the covering portion 26c of the weather strip 26 is pushed by the lower surface of the panel 21 and falls down along the main body portion 26a. As a result, the outer peripheral edge portion 21a is equally urged inward from the covering portion 26c, and the panel 21 is accurately positioned with respect to the inner panel 22 and the like. The covering portion 26c that has fallen along the main body portion 26a is pulled back along the upper surface of the panel 21 using an appropriate jig. Thereby, the upper surface of the outer peripheral edge portion 21a of the panel 21 is covered with the covering portion 26c.

  On the other hand, when the inner panel 22 is overlaid on the panel 21, the lip portion 26 e of the weather strip 26 is elastically brought into contact with the lower surface of the panel 21 while being pushed down. The lip portion 26e that elastically contacts the lower surface of the panel 21 while facing the adhesive 27 has a gap between the sandwiched portion 26b and the lower surface of the panel 21 where the adhesive 27 in the applied state is spread as described above. Suppresses intrusion from.

  Further, as shown in FIG. 3, the adhesive 27 in the applied state is released at the position of the notch 22c of the inner panel 22, so that the adhesive 27 is in contact with the tip of the sandwiched portion 26b. A bulging portion 27a bulging from the notch 22c is formed. Needless to say, the bulging portions 27 a are formed at four locations in accordance with the arrangement of the notches 22 c of the inner panel 22. The state of the adhesive 27 interposed between the lower surface of the panel 21 and the upper surface of the inner panel 22 can be visually confirmed through the notches 22c.

  Note that, even at the position of the notch 22c of the inner panel 22, the adhesive 27 is in contact with the tip of the sandwiched portion 26b, so that rainwater or the like that has entered from the gap between the outer peripheral edge portion 21a of the panel 21 and the covering portion 26c. However, it is possible to similarly prevent the adhesive 27 from entering inward through the gap between the outer peripheral edge portion 21a and the sandwiched portion 26b.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, the state of the adhesive 27 can be visually confirmed through the notch 22c at the position where the notch 22c is formed. Then, for example, based on the state where the adhesive 27 does not reach the tip of the sandwiched portion 26b, it is possible to confirm the state of the seal of the adhesive 27 having the function as a sealer.

  (2) Normally, when the adhesive 27 is applied to the lower surface of the panel 21 using an automatic coating machine, the adhesive 27 is out of seal at the corner of the outer peripheral edge 21a of the panel 21. Cheap. This is because the application amount becomes unstable due to the centrifugal force acting on the adhesive 27 extruded from the automatic applicator at the corner portion. In the present embodiment, by arranging the notch 22c in the corner portion 22b of the inner panel 22, it is possible to increase the possibility that the state of the adhesive 27 being out of seal can be found.

  (3) In the present embodiment, the inner panel 22 has a four-divided structure including the side frames 23, the front frame 24, and the rear frame 25, and the gap C1 formed between the tips of the four corner portions 22b. , C2 can be formed as notches 22c. Moreover, since it is not necessary to cut out from one steel plate with a press etc. and form the inner panel 22, it becomes possible to improve a yield.

  (4) In the present embodiment, when the lower surface of the panel 21 and the upper surface of the inner panel 22 are joined with the adhesive 27, the adhesive 27 in an applied state that is spread between them is formed between the sandwiched portion 26 b and the panel 21. Intrusion from the gap on the lower surface can be suppressed by the lip portion 26e.
