Description

  The present invention relates to a vehicular packing that is interposed between the body panel and the mounting part when the vehicle body panel is fixed to the body panel using a fastening member.

For example, when a door or the like of a vehicle such as an automobile is fixed to a body panel so as to be rotatable, a structure in which a hinge is disposed between them is employed.
The hinge is usually composed of two connecting pieces that are engaged with a shaft body serving as a rotation shaft so as to be relatively rotatable. And by fixing each connection piece to a door and a body panel, respectively, both can be connected so that rotation is possible. In this case, the hinge connecting piece and the body panel are fixed by fastening parts such as bolts (see Patent Document 1).

  As shown in Patent Document 1, when the hinge connecting piece and the body panel are fixed by fastening parts, a vehicle packing is interposed between the two in order to prevent loosening and intrusion of rainwater from the through hole. Let The vehicular packing to be used is generally made of a plate-like body having an appropriate hardness and has a through-hole through which a fastening part passes.

  By the way, the vehicle body panel and the like are coated with both an improvement in appearance characteristics and rust prevention in a state where a door and the like are assembled. However, in a narrow gap such as between the body panel and the connecting piece of the hinge, the paint is not sufficiently supplied, and a portion where the metal material is exposed as it is unpainted easily remains. If this unpainted part is left as it is, it will be difficult to prevent rusting of this part. For this reason, measures such as applying a rust preventive sealer after application is complete, applying spray wax, or placing a pre-formed sealing material before application have been taken. .

Japanese Patent Laid-Open No. 62-160383

  However, since the fastening and fixing part is a part that is difficult to apply in shape, it is not easy to apply a sealer or a spray wax after the application. Therefore, there are cases where the unpainted portion cannot always be reliably covered with a sealer or wax. Moreover, in order to improve the assembly workability | operativity of the packing for vehicles, the through-hole is largely set with respect to the diameter of a fastening component (bolt). Therefore, a gap is generated between the through hole and the bolt, and the position of the vehicular packing is likely to shift. As the position of the vehicular packing is shifted, the workability of applying a sealer or spray wax tends to be further deteriorated. Therefore, the sealing performance is deteriorated, and the required rust prevention and waterproof performance may not be obtained.

  Such a problem may occur not only in the hinge fixing portion but also in a structural portion in which a component is fixed to a body panel in a vehicle by a fastening member.

  SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and has a vehicle packing capable of easily and reliably sealing a sealed portion in a structure in which a component is fixed to a body panel in a vehicle by a fastening member. It is something to be offered.

The present invention is a vehicle packing that is interposed between the body panel and the mounting component when the mounting component is fixed to the body panel in the vehicle by a fastening member,
A packing main body made of a plate-like body having a through-hole for penetrating the fastening member;
A seal member disposed around the outer peripheral end surface of the packing body,
The seal member is made of a material that is fluidized by heating during the paint baking process of the body panel, and an outer peripheral portion of the seal member stands on the mounting component side so as to face the side surface of the mounting component. A vehicular packing having a standing portion to be installed (claim 1).

  As described above, the vehicle packing includes the packing main body having the same function as the conventional packing, and the seal member disposed around the outer peripheral end surface of the packing main body. The seal member is made of a material that is fluidized by heating at the time of painting and baking the body panel, and is erected on the side of the mounting part so as to face the side surface of the mounting part. On the outer periphery.

  Therefore, the vehicle packing is interposed between the body panel and the mounting component, and bolts are passed through and fastened to through holes provided in the packing main body portion of the vehicle packing. The main body can obtain the same packing function as before, that is, the function of preventing loosening and the intrusion of rainwater from the bolt hole.

  Furthermore, the said packing for vehicles has the said sealing member around the said packing main-body part. The seal member is made of a material that is fluidized by heating. Therefore, when the body baking process is performed on the body panel with the vehicle packing interposed between the body panel and the mounting part, the seal member is heated and fluidized.

On the other hand, the coating film formed by painting the body panel is easily formed at least up to the surface of the body panel and the mounting part and the periphery of the portion where they face each other. It is difficult to form a coating film on the surface, and unpainted parts are likely to remain.
Here, in the vehicular packing of the present invention, since the seal member fluidizes as described above, the fluidized seal member covers an unpainted portion around the seal member, and the body panel and the attachment part. And reaches the end of the coating film facing the fixed part. Thereby, it can prevent that an unpainted part remains exposed and can improve a rust prevention effect.

  Moreover, the said packing for vehicles has provided the said standing part in the outer peripheral part of the said sealing member, and this standing part is distribute | arranged so as to oppose the side surface of the said attachment component. The vehicle packing can be positioned in the plane direction with respect to the mounting part. Due to the presence of the standing portion, it is possible to prevent the positional deviation between the vehicle packing and the mounting part. Thereby, when the said sealing member is distribute | arranged to an appropriate position and the said sealing member fluidizes, between the said attachment components and the said body panel can be covered reliably. Therefore, rust prevention performance and waterproof performance can be improved with certainty. In addition, the said standing part may be provided continuously so that the outer periphery of the said attachment components side surface may be enclosed, and you may provide partially.

  Thus, according to the vehicular packing of the present invention, it is possible to provide a vehicular packing capable of easily and surely sealing a sealed portion in a structure in which a mounting part is fixed to a body panel in a vehicle by a fastening member. it can.

  In the present invention, the representation of the shape such as a rectangle is not limited to the concept of a narrow sense of geometry, and generally includes a shape that can be recognized as the above shape, each side is slightly curved, Naturally, it is also allowed to provide a curved surface called a fillet in which roundness or the like necessary for molding is formed at corners or surfaces.

Moreover, the packing for vehicles of this invention consists of the said packing main-body part and the said sealing member. As said packing main-body part, the thing similar to the packing conventionally used for the fastening part is applicable. For example, there is an inorganic fiber or aramid fiber that does not contain asbestos, an inorganic filler added, and a binder molded with an oil-resistant synthetic rubber.
Moreover, the said packing main-body part does not necessarily need to be comprised only with 1 sheet, You may combine a several thing. For example, when two through holes for penetrating bolts are required, the packing main body portion may be constituted by two portions each having one through hole.

  Moreover, the said vehicle packing does not necessarily need to be integrated, if the structure which arrange | positions the said sealing member to the outer peripheral end surface of the said packing main-body part is taken. However, when the seal member is fluidized, it is necessary to arrange the seal member in an appropriate position in advance so as to always cover the entire outer peripheral surface of the packing main body.

In addition, the material that is fluidized by heating that forms the sealing member refers to a material that can be easily changed in shape by melting by heat and decreasing its viscosity. Various known materials can be applied as the material that is fluidized by heating. For example, synthetic rubber, thermoplastic resin, or both can be used as a main component.
Examples of the synthetic rubber include butadiene rubber, isoprene rubber, styrene / butadiene rubber, and acrylonitrile / butadiene rubber.
Examples of the thermoplastic resin include polyethylene, ethylene / propylene copolymer, ethylene / propylene / diene copolymer, ethylene / vinyl acetate, ethylene / ethyl acrylate, ethylene / methyl methacrylate, styrene / butadiene block copolymer, styrene / ethylene / butadiene / Examples include styrene block copolymers and styrene / ethylene / propylene / styrene block copolymers.

Moreover, since the heating temperature of the coating baking process is approximately 150 ° C. to 210 ° C., it is necessary to set a temperature at which the seal member fluidizes. This adjustment can be performed by adjusting the composition of the chemical components of the material.
Moreover, it is preferable that the said sealing material is non-adhesive in the state before a heating. In this case, the positioning of the vehicle packing can be facilitated, and the mounting workability can be improved.

In this case, since the sealing member expands and expands and its volume increases, a wider range can be covered with the sealing member expanded and expanded. Therefore, waterproofing and rust prevention performance can be improved more reliably.

Various known materials can be applied as the foam material. For example, the above-described synthetic rubber and / or thermoplastic resin can be used as a main component, and a chemical foaming agent can be contained in these.
Examples of the chemical foaming agent include azodicarbonamide, N, N′-dinitrosopentamethylenetetramine, 4,4′-oxybisbenzenesulfonylhydrazide, and the like.

The sealing member preferably contains a crosslinking agent or a filler. Thereby, the intensity | strength of the sealing member after foaming expansion can be improved.
Examples of the crosslinking agent include dialkyl peroxides, peroxy esters, peroxy ketals, and the like.
Examples of the filler include inorganic fillers such as calcium carbonate, talc, mica, and quicklime.
Further, as described above, since the heating temperature of the coating baking process is approximately 150 ° C. to 210 ° C., it is necessary to set the temperature at which the seal member fluidizes and expands within this heating temperature range. This adjustment can be performed by adjusting the chemical composition of the material and selecting the foaming agent.

Moreover, in the said packing for vehicles, it is preferable that the said sealing member is joined to the outer peripheral end surface of the said packing main-body part, and is integrated with this packing main-body part (Claim 3).
In this case, the vehicle packing can be handled as one component. Therefore, handling becomes easy and assembly workability can be improved.

In the above-described packing for a vehicle in which the packing main body and the seal member are integrated, it is preferable that the sealing member is formed on the outer periphery of the packing main body by injection molding.
In this case, the sealing member and the standing portion can be easily formed on the vehicle packing, and the shape accuracy can be improved. Therefore, it is possible to improve the positioning accuracy of the vehicular packing with respect to the mounting part and more reliably prevent the displacement.

Moreover, it is preferable that the said vehicle packing is comprised so that the said standing part can be arrange | positioned in the state contact | abutted to the side surface of the said attachment component.
In this case, the positioning effect by the standing portion can be further improved. For this reason, it is possible to more reliably prevent the displacement of the vehicle packing with respect to the mounting component.

In the vehicular packing, a surface of the upright portion that faces the mounting component is provided with a standing concave step for forming a gap between the mounting component and the front end. (Claim 6).
In this case, the seal member heated and fluidized by the paint baking process can be reliably formed on the paint film applied to the attachment part. That is, when painting is performed in the state before the paint baking process, the attachment part is painted to the inside of the gap due to the presence of the gap. Then, by performing the coating baking process, the fluidized seal member fills the gap, and a seal body is formed on the coating film. Therefore, rust prevention performance can be further improved.

In the vehicle packing, a bottom surface stepped portion for forming a gap between the seal panel and the body panel may be provided on a surface of the seal member in contact with the body panel at an outer peripheral end thereof. Preferred (claim 7).
In this case, the fluidized seal member heated and fluidized by the paint baking process can be reliably formed on the paint film applied to the body panel. That is, when painting is performed in a state before the coating baking process, the body panel is painted to the inside of the gap due to the presence of the gap. Then, by performing the coating baking process, the fluidized seal member fills the gap, and a seal body is formed on the coating film. Therefore, rust prevention performance can be further improved. In addition, the said bottom face recessed step part may be provided in the perimeter of the outer peripheral end part of the said sealing member, and may be provided partially.

In the vehicular packing, it is preferable that a locking portion for engaging and holding the vehicular packing on the mounting part is provided in the standing portion.
In this case, it is not necessary to temporarily fix the vehicle packing to the mounting part or the body panel using an adhesive or the like. Therefore, the assembling work can be facilitated and the assembling workability can be improved.

Further, the seal member 2 has non-adhesiveness in a state before heating, and can be easily slid without being adhesively bonded even if it is brought into contact with the body panel 8 and the second connecting piece 72. Is possible.

  Further, the outer shape of the seal member 2 is substantially rectangular as shown in FIG. 1, and the outer peripheral dimension thereof is set larger than the outline of the second connecting piece 72. As shown in FIGS. 2 and 3, the bottom surface 26 of the seal member 2 that contacts the body panel 8 is provided with a bottom concave step 25 for forming a gap between the bottom surface 26 and the body panel 8. It is. The bottom concave step portion 25 is formed by retreating from the bottom surface 26 in a direction away from the body panel 8. In addition, the upper surface of the seal member 2 has two first standing portions 21 and two second standing portions 22.

  The first upright portion 21 and the second upright portion 22 are connected to the second connecting portion from a position outside the outline of the second connecting piece 72 in a plan view (plan view) viewed from the direction of the arrow in FIG. It arrange | positions so that it may stand in the piece 72 side. As shown in FIGS. 2 and 3, the first standing portion 21 and the second standing portion 22 have a first facing surface 211 and a second facing surface 221 that face the side surface of the second connecting piece 72. The two connecting pieces 72 are arranged so as to contact the side surfaces.

As shown in FIG. 3, the first facing surface 211 of the first standing portion 21 is provided with a locking portion 212 for engaging and holding the vehicle packing 1 with the second connecting piece 72. The locking portion 212 is configured to protrude from the position on the distal end side of the first facing surface 211 toward the second connecting piece 72 and engage with the upper surface of the second connecting piece 72.
In addition, as shown in FIG. 2, the second facing surface 221 of the second standing portion 22 has a standing concave step portion 222 for forming a gap between the second connecting piece 72 and the tip end side thereof. It is provided. The standing recessed step 222 is formed by retreating from the second facing surface 221 in a direction away from the side surface of the attachment component 7. In addition, the corner portion formed by the upper surface of the seal member 2 and the second facing surface 221 is curved so as to follow the shape of the second connecting piece 72.

Next, a method for fixing the attachment part 7 and the body panel 8 using the vehicular packing 1 having the above configuration will be described.
First, as shown in FIG. 3, the vehicular packing 1 is engaged and held on the second connecting piece 72 using the locking portion 212 described above. At this time, the first facing surface 211 and the second facing surface 221 of the first standing portion 21 and the second standing portion 22 are in contact with the side end surface of the second connecting piece 72, whereby the vehicle with respect to the second connecting piece 72. The position of the packing 1 is determined. At the same time, a state is realized in which the through holes 11 and 12 and the component through holes 721 and 722 are aligned on the same axis. Next, two bolts 61 are respectively connected to the component connecting holes 721, 722, the through holes 11, 12, and the body through holes 81, 82 on the second connecting piece 72 holding the vehicle packing 1 and the body panel 8. Pass in order. Then, as shown in FIG. 2, the nut 62 is fastened and fixed to the tip end side of the bolt 61 protruding from the body through holes 81 and 82. Thus, a fastening and fixing structure in which the vehicle packing 1 is interposed between the second connecting piece 72 and the body panel 8 is obtained.

  Next, the body panel 8 is painted and baked. In this example, the whole body panel 8 and all the parts fixed to the body panel 8 are immersed in the paint, so-called electrodeposition coating is performed in which the paint is applied to the entire surface and electrodeposited. At this time, as shown in FIG. 4, by the standing recessed step portion 222 and the bottom surface recessed step portion 25 provided on the seal member 2, the second connection piece 72 and the body panel 8, and the seal member 2, respectively. A substantially U-shaped gap is formed. Therefore, coating films 723 and 83 are formed on the surfaces of the second connecting piece 72 and the body panel 8 located inside the gap on the opening side of the gap. On the other hand, on the surface on the bottom side of the gap, the paint does not sufficiently penetrate and the coating films 723 and 83 are not formed. Therefore, before the baking treatment is performed, unpainted portions 79 and 89 exist between the coating film end surfaces 724 and 84 and the fixed portion.

  Further, as shown in FIG. 5, at least the surface where the second connecting piece 72 faces the upper surface of the seal member 2 and the corner formed by the upper surface of the body panel 8 and the side surface of the seal member 2 are sufficiently infiltrated. Thus, the coating films 723 and 83 are not formed. For this reason, as in the case of the gap, unpainted portions 79 and 89 exist between the coating film end faces 724 and 84 and the fixed portion before the baking treatment is performed. The unpainted portions 79 and 89 are portions where the metal material of the body panel 8 or the second connecting piece 72 is exposed as it is.

  Next, a paint baking process is performed. Thereby, the coating films 723 and 83 are baked, and the seal member 2 of the vehicular packing 1 gradually expands and expands as shown in FIGS. The seal member 2 covers the unpainted portions 79 and 89 while filling the gap between the body panel 8 and the second connecting piece 72 and finally covers the end surfaces 724 and 84 of the coating films 723 and 83. A state in which the membranes 723 and 83 and the seal member 2 are connected is obtained. Further, as shown in FIG. 6, in the standing concave step portion 222 and the bottom concave step portion 25, the seal member 2 that is fluidized and foamed and expanded covers the upper surface of the coating film 723, and the sealing member foamed with the coating film 723. 2 is obtained.

Next, the function and effect of this example will be described.
As shown in FIG. 1, the vehicular packing 1 includes a packing main body portion 10 having a function similar to that of a conventional packing, and a seal member 2 disposed around the outer peripheral end surface of the packing main body portion 10. The seal member 2 is made of a foam material that expands and expands by heating during the coating baking process of the body panel 8. Further, the seal member 2 includes a first standing portion 21 and a second standing portion 22 that are erected on the second coupling piece 72 side from a position outside the region where the second coupling piece 72 and the vehicle packing 1 abut. have.

  Therefore, as shown in FIG. 2, the vehicle packing 1 is interposed between the body panel 8 and the mounting part 7, and the fastening member 6 is passed through the through holes 11 and 12 of the packing main body 10 of the vehicle packing 1. First, the same packing function as before, that is, the function of preventing loosening and the intrusion of rainwater from the body through holes 81 and 82 can be obtained.

  Furthermore, the vehicular packing 1 has a seal member 2 around the packing main body 10. The sealing member 2 is made of a foam material that expands and expands. Therefore, as shown in FIGS. 4 and 5, when the paint baking process of the body panel 8 is performed with the vehicle packing 1 interposed between the second connecting piece 72 and the body panel 8, The member 2 is heated and expanded.

  As shown in FIGS. 6 and 7, the foamed and expanded sealing member 2 covers the surrounding unpainted portions 79 and 89 and faces the fastening and fixing portion between the second connecting piece 72 and the body panel 8. , 83 is reached and covered. Thereby, it can prevent that the unpainted parts 79 and 89 remain exposed, and can improve a rust prevention effect.

  Moreover, the vehicle packing 1 has the 1st standing part 21 and the 2nd standing part 22 in the sealing member 2, as shown in FIGS. 1-3. As shown in FIGS. 2 and 3, the first standing portion 21 and the second standing portion 22 are arranged on the outer peripheral portion of the seal member 2 with the second connecting piece 72 and the seal member so as to face the side surface of the mounting part 7. The first upright portion 21 and the second upright portion 22 can be arranged in contact with the side surface of the second connecting piece 72 from a position outside the region where 2 contacts. As shown in FIG. 3, the first standing portion 21 is provided with a locking portion 212 for engaging and holding the vehicle packing 1 with the second connecting piece 72. Furthermore, the sealing member 2 has non-adhesiveness in a state before heating.

  Therefore, positioning of the vehicular packing 1 in the plane direction with respect to the second connecting piece 72 can be easily and accurately performed, and positional deviation between the vehicular packing 1 and the second connecting piece 72 can be prevented. Thereby, when the seal member 2 is arranged at an appropriate position and the seal member 2 is expanded and expanded, the space between the second connecting piece 72 and the body panel 8 can be reliably covered. Therefore, rust prevention performance and waterproof performance can be improved with certainty. Further, the workability of assembling can be improved by engaging and holding the vehicular packing 1 with the second connecting piece 72.

  The seal member 2 is formed on the outer periphery of the packing main body portion 10 by injection molding, and is integrated with the packing main body portion 10. Therefore, it is possible to easily form the seal member 2, the first standing portion 21, and the second standing portion 22 in the vehicle packing 1, and to improve the shape accuracy. Therefore, the positioning accuracy of the vehicular packing 1 with respect to the attachment component 7 can be improved, and the displacement can be prevented. Further, since the vehicular packing 1 can be handled as one component, the handling becomes easy and the assembling workability can be improved.

  In addition, as shown in FIG. 2, the second facing surface 221 of the second standing portion 22 has a standing concave step portion 222 for forming a gap between the second connecting piece 72 and the tip end side thereof. Each is provided. Therefore, the sealing member 2 heated and boiled and expanded by the coating baking process can be reliably formed on the coating film 723 applied to the second connecting piece 72. Therefore, the rust prevention performance by the seal member 2 can be further improved.

  Further, as shown in FIG. 3, a bottom surface stepped portion 25 for forming a gap between the sealing member 2 and the body panel 8 is provided on the outer peripheral end of the surface where the sealing member 2 contacts the body panel 8. Yes. Therefore, the sealing member 2 heated and boiled and expanded by the coating baking process can be reliably formed on the coating film 83 applied to the body panel 8. Therefore, the rust prevention performance by the sealing member 2 can be further improved.

  Thus, in this example, the above-mentioned special vehicle packing 1 is used, and the second connecting piece is formed by the first standing portion 21 and the second standing portion 22 provided on the seal member 2 of the vehicle packing 1. 72 can be positioned and engaged and held. Then, the attachment part 7 can be fastened and fixed to the body panel 8 via the vehicle packing 1, and the unpainted portions 79 and 89 can be covered with the foamed and expanded seal member 2 during the subsequent paint baking process. For this reason, it is possible to facilitate the joining operation of the attachment part 7 and the body panel 8 and to prevent a seal failure caused by the displacement of the vehicle packing 1. Therefore, it is possible to obtain a structure capable of exhibiting an excellent waterproof effect and rust preventive effect.

  In particular, as in this example, the hinge (assembly part 7) for fixing the flip-up type back door has its axial direction oriented in the horizontal direction, so that rainwater is in contact with the second connecting piece 72 of the hinge. It tends to accumulate in the gap with the body panel 8. However, in the structure in which the seal member 2 covers the coating film 723 as in this example, it is possible to reliably prevent the hinge and the body panel 8 from being rusted by rainwater.

(Example 2)
This example is an example in which the shape of the seal member of the vehicular packing 1 in the first embodiment is changed.
As shown in FIGS. 8 and 9, the seal member 201 in the vehicle packing 1 of the present example has a rectangular outer shape as in the first embodiment, and two vertical portions are formed on two corners positioned diagonally. An installation section 202 is provided. Further, the standing portion 202 has a substantially L-shaped cross-sectional shape in a plan view, and is configured to position the corner portion of the second connecting piece 72 by two surfaces arranged on the inner side. It is. Other configurations are the same as those of the first embodiment.

  The shape, the arrangement location, and the number of arrangements of the standing portion shown in this example are one example, and can be appropriately changed depending on the shape of the attachment part 7. For example, the standing portion may be provided continuously so as to surround the entire outer periphery on the side surface of the attachment component 7, or may be provided partially as shown in the first embodiment and this example. Further, when the body panel has a concavo-convex shape and can be positioned, a standing portion can be formed on the body panel side.

(Example 3)
This example is an example in which the configuration of the vehicular packing 1 in the first embodiment is changed.
That is, as shown in FIG. 10, the vehicular packing 101 of the present example is the same as the vehicular packing 1 of the first embodiment, as shown in FIG. 10A, the seal member 2 shown in FIG. Is configured to be separable as a separate body. In use, the seal member 2 is disposed around the packing body 10. Other configurations are the same as those of the first embodiment.
