Description

The present invention relates to a resin window structure, for example, a resin window structure used in a vehicle such as an automobile.

In recent years, resin windows have been used in place of steel plates and flat glass for roofs and the like in order to reduce the weight of vehicles. A technique for attaching a resin panel of a resin window to the roof of a vehicle is disclosed in the following patent documents. For example, the edge of the resin panel of Patent Document 1 is adhered to the flange of the roof side rail with a urethane adhesive. Therefore, by elastically displacing the urethane adhesive, the sealing property is ensured while absorbing the thermal expansion and contraction of the resin panel. The lower surface of the resin panel of Patent Document 2 is slidably contacted with the lip portion of the weather strip. As a result, the sealing property is ensured while absorbing the thermal expansion and contraction of the resin panel.

However, in the above-mentioned conventional resin window structure, it is necessary to make further improvements in terms of ensuring strong fastening to the vehicle body and high sealing performance while dealing with thermal expansion and contraction of the resin panel. In the technique disclosed in Patent Document 1, when the resin panel becomes larger, there is a limit to the fastening and sealing properties with the urethane adhesive. Further, as disclosed in Patent Document 2, it is difficult to secure high sealing performance by sliding the lip portion of the weather strip.

Therefore, there has been a prior need for a resin window structure that absorbs thermal expansion and contraction of the resin panel and ensures strong fastening to the vehicle body and higher sealing performance.

According to one feature of the present disclosure, the resin window structure has a resin panel and a body having an opening closed by the resin panel. The resin panel is fastened by a fastening member around the opening of the body. The space between the resin panel and the opening of the body is sealed by a sealing member made of a different material from the fastening member. The fastening member and the sealing member each have a displacement absorbing portion that absorbs the displacement of the resin panel in the surface direction with respect to the body.

Therefore, the resin panel is firmly fastened to the body by the fastening member. Further, a sealing member made of a material different from the fastening member ensures high sealing performance with respect to the body of the resin panel. Displacement absorbing portions are provided on the fastening member and the sealing member, respectively. This displacement absorbing portion absorbs the displacement of the resin panel in the plane direction mainly due to thermal expansion and contraction.

According to another feature of the present disclosure, the sealing member is covered and integrated with the fastening member. Therefore, the fastening member and the sealing member can be handled as one component. Thereby, the assembling property of the resin window structure can be improved. Further, the resin window structure can be simplified and made compact.

According to another feature of the present disclosure, the displacement absorbing portion of the fastening member is a bent portion that stands up from the body toward the resin panel and allows elastic deformation. Therefore, the bent portion of the fastening member is elastically deformed to absorb the displacement of the resin panel in the surface direction.

According to another feature of the present disclosure, the displacement absorbing portion of the fastening member and the displacement absorbing portion of the sealing member are bent portions that stand up from the body toward the resin panel. A gap is formed between the bent portion and the body to allow elastic deformation of the fastening member and the sealing member. Therefore, the bent portion of the fastening member and the bent portion of the seal member are elastically deformed within the gap range, so that the resin panel is allowed to be displaced in the surface direction. Since the fastening member and the sealing member are integrated, it is possible to reduce the size of the gap that allows displacement of both bent portions.

According to another feature of the present disclosure, the fastening member has a sandwiching portion that covers the peripheral edge portion of the resin panel and is coupled to the peripheral edge portion. Therefore, the resin panel is firmly fastened to the body by the sandwiching portion.

According to another feature of the present disclosure, the outer surface of the resin panel is provided with an engaging groove in which the tip of the sandwiching portion is locked. Therefore, the bonded state of the sandwiched portion with respect to the resin panel is firmly maintained.

According to other features of the present disclosure, the fastening member is fixed to the body. Therefore, the configuration on the resin panel side can be simplified. As the fixing means for fixing the fastening member to the body, means such as screwing, bonding, and welding can be used.

According to another feature of the present disclosure, the sealing members are arranged in parallel on the outer peripheral side of the fastening member. Therefore, it is possible to surely realize a strong fastening state of the resin panel with the body by the fastening member and a high sealing property of the resin panel with the body by the sealing member. Further, by using the fastening member and the sealing member as separate members, it is possible to suppress the maintenance cost at the time of parts replacement and improve the maintainability at the time of replacement work. Further, sealing of the fastening member by the sealing member is realized.

According to another feature of the present disclosure, the seal member has an outer surface in contact with the body and an inner surface in contact with the resin panel, and has a seal body attached to the body. Therefore, the seal member is attached to the body via the seal body. The outer surface of the seal body is in contact with the body, the inner surface of the seal body is in contact with the resin panel, and the space between the resin panel and the body is sealed.

According to another feature of the present disclosure, the sealing member has a sandwiching portion that covers the peripheral edge portion of the resin panel and is adhered to the peripheral edge portion. Therefore, the sandwiching portion of the sealing member sandwiches and covers the peripheral edge portion of the resin panel and is adhered to form a seal between the resin panel and the body.

According to another feature of the present disclosure, the sealing member has an adhesive portion that is adhered to the inner surface of the resin panel facing the peripheral edge of the opening of the body. Therefore, the adhesive portion of the sealing member is adhered to the inner surface of the resin panel to seal between the resin panel and the body. By arranging the sealing member in a state where it is adhered to the inner surface of the resin panel and does not protrude from the edge portion, the appearance of the main edge portion of the resin window can be improved.

According to another feature of the present disclosure, the displacement absorbing portion of the seal member is an elastically deformable extending portion that extends from the body with a bent portion. The tip of the extension is attached to the resin panel. Therefore, the extended portion of the seal member is elastically deformed at the bent portion, and the displacement of the resin panel in the surface direction is absorbed. Further, the tip of the extending portion as the displacement absorbing portion is attached to the resin panel to seal between the resin panel and the body.

According to another feature of the present disclosure, the sealing member has a sandwich. The sandwiching portion covers the peripheral edge portion of the resin panel. The sandwiching portion sandwiches the peripheral edge portion so that the peripheral edge portion of the resin panel can be displaced in the surface direction of the resin panel. Therefore, the peripheral portion of the resin panel is sandwiched by the sandwiching portion of the sealing member, and the seal between the body and the resin panel is made. Since the peripheral edge portion can be displaced in the surface direction of the resin panel with respect to the sandwiched portion as the displacement absorbing portion, the displacement in the surface direction of the resin panel is absorbed.

According to another feature of the present disclosure, a drain hole is provided at the bottom of the sandwich. Therefore, water such as rainwater that has entered the sandwiched portion is drained to the outside of the sandwiched portion through the drain hole. As a result, the sealing property of the sealing member between the body and the resin panel is further enhanced.

According to another feature of the present disclosure, the resin panel has a hooking portion that projects from an inner surface facing the body. The fastening member has a locking arm that is hooked on the hooking portion and contacts the hooking portion so that the hooking portion can be displaced in the surface direction of the resin panel. Therefore, the resin panel is fastened to the body by hooking the locking arm of the fastening member to the hooked portion of the resin panel. By displacing the locking arm relative to the hooking portion, the displacement of the resin panel in the surface direction is absorbed.

According to other features of the present disclosure, the fastening member has an elastic portion. The elastic portion is attached to the body and elastically holds the hooked portion of the resin panel with respect to the body in the thickness direction of the resin panel. Therefore, the hooking portion is elastically held by the elastic portion, and rattling of the resin panel of the locking arm with respect to the hooking portion in the thickness direction is suppressed. As a result, rattling in the thickness direction of the resin panel is suppressed, and the fastening force of the resin panel by the fastening member is enhanced.

According to another feature of the present disclosure, the sealing member has a sealing body that engages with the peripheral edge of the resin panel. The displacement absorbing portion of the seal member extends from the seal body with a bent portion so that it can be elastically deformed. Therefore, the seal member is coupled to the peripheral edge of the resin panel via the seal body. The displacement absorbing portion extends from the seal body to the body side via an elastically deformable bent portion. The elastic deformation of the bent portion absorbs the displacement of the resin panel in the surface direction.

According to other features of the present disclosure, the fastening member and the sealing member are fixed to the body. Therefore, the configuration of the resin panel can be simplified. As the fixing means for fixing the fastening member and the sealing member to the body, means such as screwing, bonding, and welding can be used.

The extending portion 56 is provided with a U-shaped sandwiching portion 56a that sandwiches the left edge portion of the resin panel 10 in the plate thickness direction. A gap 12 in the surface direction (left-right direction) of the resin panel 10 is provided between the inside of the sandwiching portion 56a and the left end edge of the resin panel 10. The gap 12 absorbs the displacement of the resin panel 10 in the surface direction with respect to the sandwiched portion 56a.

In the fifth embodiment, the extension portion 56 is provided with a drain hole 56b. The drain hole 56b is provided on the lower side of the sandwiching portion 56a. Water such as rainwater that has entered the gap 12 is drained from the gap 12 to the drainage channel 8 through the drain hole 56b. The drainage channel 8 is provided along the roof side rail 5. The water drained into the drainage channel 8 flows to the front or the rear of the vehicle and is drained from the vehicle body 1.

Further, in the fastening member 40, the fastening screw 42 is configured to be relatively displaceable in the surface direction of the resin panel 10 with respect to the boss portion 41. Further, in the seal member 50, a gap 12 is provided between the sandwiching portion 56a and the left end edge portion of the resin panel 10. As a result, for each of the fastening member 40 and the sealing member 50, a displacement absorbing portion for absorbing the displacement of the resin panel 10 in the surface direction is formed. Since the displacement of the edge of the resin panel 10 due to thermal expansion and contraction is absorbed by the gap 12 and cannot be seen from the outside, the appearance of the parting portion of the resin window 3 can be improved.

Further, the seal body 51 is sandwiched between the resin panel 10 and the flange portion 5a, and the extending portion 56 extending from the seal body 51 is coupled to the left edge portion of the resin panel 10 via the sandwiching portion 56a. As a result, the space between the resin panel 10 and the vehicle body 1 is doubly sealed, thereby ensuring high sealing performance of the resin window 3.

Further, in the case of the fifth embodiment, the drainage channel 8 is sealed by the auxiliary lip portion 56c, and the sealing property of the seal main body 51 is indirectly enhanced. Further, as in the third and fourth embodiments, in the fifth embodiment, the fastening member 40 and the sealing member 50 are used as separate members, so that the maintenance cost at the time of parts replacement can be suppressed, and the maintenance at the time of replacement work can be suppressed. You can improve your sex.

Further, since the seal member 50 is arranged on the outer peripheral side of the fastening member 40, the sealing member 50 also seals the fastening member 40. Further, since the structure does not use the urethane adhesive, it is possible to prevent problems such as a decrease in fastening strength due to deterioration of the urethane adhesive.

FIG. 7 shows the resin window structure according to the sixth embodiment. In the sixth embodiment, a black auxiliary plate 13 is laminated on the inner surface of the resin panel 10 in place of the shielding layer 9 of the first to fifth embodiments. The auxiliary plate 13 is integrally molded on the inner surface of the peripheral edge of the resin panel 10 in a certain width region by so-called two-color molding. The auxiliary plate 13 is arranged so as to face the flange portion 5a of the roof side rail 5.

On the lower surface of the auxiliary plate 13, an L-shaped hook portion 13a projecting toward the flange portion 5a is provided. The hook portion 13a is provided so as to open to the right. The locking arm 45a of the fastening member 45 is hooked on the hooking portion 13a from the right side. The locking arm 45a is hooked to the hooking portion 13a so as to be relatively displaceable in the surface direction of the resin panel 10. The hooking portion of the locking arm 45a with respect to the hooking portion 13a constitutes a displacement absorbing portion for absorbing the displacement of the resin panel 10 in the surface direction.

The fastening member 45 is a spring clip manufactured by bending a leaf spring material, and is screwed to the flange portion 5a by a fastening screw 46. The fastening member 45 is provided with a leaf spring-shaped elastic portion 45b in addition to the locking arm 45a. The elastic portion 45b is elastically pressed against the lower surface of the hook portion 13a. The hooking portion 13a is pressed and held by the elastic portion 45b in the thickness direction of the resin panel 10. By elastically urging the hooking portion 13a upward by the elastic portion 45b, the elastically pressed state of the locking arm 45a against the hooking portion 13a is maintained, and eventually the fastening member 45 rattles the fastening state of the resin panel 10. Is prevented.

The left end portion of the auxiliary plate 13 protrudes to the left from the left end portion of the resin panel 10. A T-shaped hooking portion 13b is provided on the protruding portion. The seal body 57a of the seal member 57 is hooked on the hook portion 13b, and the seal body 57a is supported along the left end edge of the resin panel 10. The seal body 57a has a prismatic shape with a rectangular cross section, and is joined along the left end edge of the resin panel 10 with its upper surface aligned substantially flush with the outer surface (upper surface) of the resin panel 10.

The extending portion 57b projects from the upper part of the seal body 57a. The extending portion 57b projects downward in an L shape and is connected to the upper surface of the flange portion 5a. As shown in the figure, the tip of the extending portion 57b is sandwiched between the flange portion 5a and the fastening member 45 and fastened together with the fastening screw 46. The extending portion 57b, which is bent in an L shape from the seal body 57a and is elastically deformable, functions as a displacement absorbing portion for absorbing the displacement of the resin panel 10 in the surface direction.

According to the resin window structure of the sixth embodiment configured as described above, the resin panel 10 is fastened to the flange portion 5a of the roof side rail 5 by the fastening member 45, and the roof side of the resin panel 10 is fastened by the sealing member 57. Sealing property to the rail 5 is ensured. Since the locking arm 45a of the fastening member 45 and the extending portion 57b of the sealing member 57 function as displacement absorbing portions, the displacement of the resin panel 10 in the surface direction mainly due to thermal expansion and contraction is absorbed.

In the sixth embodiment, the fastening member 45 is provided with the elastic portion 45b. The hooking portion 13a is pressed upward in the thickness direction of the resin panel 10 by the elastic portion 45b, and the elastic pressing state of the locking arm 45a against the hooking portion 13a is maintained. As a result, rattling of the resin panel 10 mainly in the thickness direction is suppressed, and by extension, the fastening force of the resin panel 10 by the fastening member 45 is enhanced.

The displacement of the resin panel 10 in the surface direction is absorbed by the displacement of the extending portion 57b that projects and curves in an L shape from the seal body 57a. Since the seal body 57a is hooked on the T-shaped hooking portion 13b and attached along the edge of the resin panel 10, rainwater or the like passes between the seal body 57a and the edge of the resin panel 10. It is possible to more reliably prevent the ingress of water.

The extending portion 57b of the seal member 57 is fastened together with the fastening member 45 by the fastening screw 46 and fixed to the flange portion 5a. Therefore, the fixing means can be simplified as compared with the configuration in which the screws are separately screwed, and the resin window structure can be simplified. Further, since the structure does not use the urethane adhesive, it is possible to prevent problems such as a decrease in fastening strength due to deterioration of the urethane adhesive.

Further changes can be made to each of the embodiments described above. For example, as a means for fixing the fastening members 20, 40, 45 and the sealing members 30, 50, 57 to the vehicle body 1 side (flange portion 5a), urethane adhesive, welding, or a clip is used instead of the screw fastening illustrated.
