Description

  The present invention relates to an automotive interior material fixing locking member that is adhesively fixed to an interior material in order to lock and fix the automotive interior material to a mating member such as a panel.

  As interior materials arranged on the vehicle interior side, resin material moldings or fiber base materials such as roof lining that covers the ceiling panel, floor carpet that covers the floor panel, luggage trim that covers the luggage panel, etc. A press-molded product is known. Although there are various methods for attaching and fixing these interior materials, it is preferable to provide a locking member that can be locked to a connecting member provided on the panel on the back surface of the interior material, that is, the surface on the panel side. ing. The locking member is bonded and fixed by applying an adhesive such as hot melt to the back surface of the interior material or the bonding surface of the locking member. At this time, one of the technical problems is that the locking member does not peel off due to a load applied to the interior material.

  This is a particularly serious problem in the locking member attached to the back surface of the roof lining. That is, a curtain airbag may be disposed along the side edge of the roof lining between the roof panel and the roof lining. When the curtain airbag is deployed, the locking member arranged on the roof panel side is detached from the receiving member, and the side edge of the roof lining is turned to the vehicle interior side, so that the curtain airbag is deployed into the vehicle interior. To do. At this time, since a large load is applied to the locking member in the direction of detachment, the locking member may be detached from the roof lining. If the locking member is peeled off from the roof lining, the locking member may be scattered to cause a danger to the passenger. For this reason, it is necessary to ensure sufficient adhesive strength between the locking member and the roof lining.

  In Patent Document 1, as a technique for increasing the adhesive strength of the locking member, a clip (locking member) capable of inserting and locking the engagement piece on the vehicle body panel side is spread and expanded from the bonding surface to the surface side. A technique of providing a tapered punched hole that opens is disclosed. The adhesive is filled into the tapered punch hole, and the clip (locking member) is firmly bonded and fixed to the interior material by the anchor effect.

Japanese Patent Laid-Open No. 9-183346

  However, even in the locking member described in Patent Document 1, sufficient adhesive strength to prevent peeling still cannot be obtained. Since the through hole (through hole) formed in the locking member is formed in a tapered shape, the opening area of the hole on the bonding surface side is small, and the adhesive is not easily filled into the through hole. For this reason, since the hooking of the adhesive material on the taper decreases and the dispersion of the adhesive force increases, sufficient adhesive strength cannot be guaranteed. As a countermeasure, when the opening area on the bonding surface side is increased, the anchor effect is decreased and the bonding area of the locking member with the interior material is decreased, resulting in a decrease in bonding strength.

  An object of the present invention is to provide a locking member for fixing a vehicle interior material that is interposed between the interior material of the vehicle and the panel and can be firmly bonded and fixed to the interior material.

  According to one embodiment of the present invention, there is provided an automotive interior material fixing locking member that is interposed between an automotive interior material and a panel and is adhesively fixed to the interior material in order to fix the interior material to the panel. The The locking member includes a main portion including a locking portion that can be locked to the connecting member attached to the panel, a back surface that faces the interior material and can be bonded to the interior material by an adhesive, and a main portion. An integrally formed flange portion having a first surface that faces the panel and a second surface that faces the interior material and can be bonded to the interior material by an adhesive. is doing. The flange portion has a through hole that passes through the flange portion between the first surface and the second surface, and the through hole includes a bridging portion that crosses the through hole in the in-plane direction of the flange portion.

  Since the bridging part that crosses the through hole in a bridging manner is provided in the through hole, the anchoring effect is easily improved by wrapping the bridging part with the adhesive, and a strong adhesive strength that cannot be obtained by the prior art is obtained. It is done.

  The bridge portion desirably has a bottom surface facing the interior material that is substantially flush with the second surface of the flange portion, and a plate thickness smaller than the plate thickness of the flange portion. In such a configuration, the adhesive can easily wrap the bridging portion when the locking member is pressed after the adhesive is applied to the interior material. For this reason, even when the extrusion amount of the adhesive to the through-hole is small, the variation in the adhesive force is reduced, and the occurrence of poor adhesion can be reduced as much as possible.

  The thickness of the bridging portion is desirably in the range of 20 to 70% of the thickness of the flange portion. By setting the thickness of the crosslinked portion in this way, it becomes easy for the adhesive to reliably wrap the crosslinked portion while ensuring the strength of the crosslinked portion.

  The through hole is connected to the constant cross section extending from the second surface to the front of the first surface with a constant cross section, and is connected to the constant cross section, to the first surface while the cross sectional area increases toward the first surface And a taper portion extending. When the through hole has a constant cross-section, the filling of the adhesive into the through hole is secured, and when the adhesive is sufficiently filled in the through hole, not only on the bridge portion but also on the inclined surface of the tapered portion. Since the adhesive is applied, the adhesion strength of the locking member is further increased.

  The upper surface of the bridge portion facing the panel is preferably located at the same height as the connection portion between the constant section and the tapered portion. At the same time as the adhesive wraps the bridging portion more reliably, the adhesive reaches the tapered portion, so that the adhesive strength of the locking member is increased.

  It is desirable that an uneven portion where the height of the flange portion changes in the plate thickness direction is provided on the upper surface of the bridging portion. Adhesive is filled in the recesses of the concavo-convex portion formed on the upper surface of the bridging portion, the anchor effect by the bridging portion is enhanced, and the adhesive strength of the locking member is further enhanced.

  It is preferable that the side surface of the bridging portion extends parallel to the plate thickness direction of the flange portion. The cross-linked portion is less likely to hinder the filling of the adhesive into the through hole, and the adhesive can reliably reach the upper surface of the cross-linked portion.

  It is desirable that a groove portion extending in the plate thickness direction of the flange portion is formed on the side surface of the through hole or the side surface of the bridge portion. Since the adhesive is filled in the groove and the anchor effect by the adhesive filled in the groove is added, the adhesive strength of the locking member is further increased.

  Two bridging portions may be provided and may cross each other in the through hole. Since the anchor effect with the adhesive by the cross-linked portion is increased, the adhesive force is improved.

  The through hole may have a rectangular cross section. By setting the through hole to have a rectangular cross section, the filling property of the adhesive is better than that of the round hole.

  As described above, according to the present invention, it is possible to provide an automotive interior material fixing locking member that can be firmly bonded and fixed to the automotive interior material.

(Lou Flying)
The roof lining 1 is formed into a shape along the shape of the roof panel by press-molding a thermoplastic substrate or a thermosetting substrate. The vehicle interior side of the base material la is covered with a skin lb made of nonwoven fabric, knit, or a laminate of at least one of nonwoven fabric or knit and urethane foam, and has a good appearance and feel suitable as an interior material.
As shown in FIG. 1, the roof lining 1 is formed with an opening 2 for attaching a console integrated with a storage box, a map lamp, and the like to the roof panel, and an opening 3 for attaching a room lamp. In addition, an opening (not shown) for attaching components such as an assist grip and a sun visor to the roof panel, and a concave portion (not shown) for accommodating these components are formed. These components are attached to the roof panel in a pre-modulated state in the roof lining 1. At this time, the roof lining 1 is fixed and held at an attachment position along the roof panel by being clamped and fixed between the component parts and the roof panel.

(Locking member)
FIG. 3 is a perspective view of the locking member 10 according to the present invention. The locking member 10 is adhesively fixed to the side of the roof lining 1 facing the vehicle body panel, that is, the surface of the base material 1a via an adhesive.

  The locking member 10 faces the metal clip 4 (connecting member) attached to the panel and a locking portion 20 that can be locked, and the roof lining 1 (interior material), and can be bonded to the roof lining 1 with an adhesive. And a main portion 11 having a back surface 12. A pair of flange portions 21 and 21 ′ formed integrally with the main portion 11 are provided on both sides of the main portion 11. The flange part 21 has the 1st surface 13 which faces a panel, and the 2nd surface 14 which faces the roof lining 1 (interior material) and can be adhere | attached on the roof lining 1 with an adhesive agent. The flange portion 21 ′ also has a first surface 13 ′ and a second surface 14 ′ having the same configuration.

  The locking member 10 is formed by injection-molding a thermoplastic resin such as polypropylene, but is not limited to this, and is not limited to this, but a thermoplastic resin such as polyethylene, polycarbonate, or polyamide, or stainless steel, aluminum, or the like. It can be replaced with metal. As an example of the external dimensions of the locking member 10, the length in the longitudinal direction is 70 mm, the length in the width direction is 16 mm, the height is 14 mm, and the plate thickness is 2 mm.

  Restriction ribs 26 and 26 'are formed between the locking portion 20 and the flange portions 21 and 21'. The movement of the metal clip 4 engaged with the locking portion 20 is restricted by the restriction ribs 26, 26 ′. For this reason, due to the relative displacement between the metal clip 4 and the locking member 10, the engagement between the metal clip 4 and the locking member 10 is released or the engagement force is reduced, so that the roof lining 1 is partially Occurrence of a problem that hangs down is prevented.

  As shown in FIGS. 2 and 3, the locking portion 20 of the locking member 10 is formed so as to protrude from the general surface 23 of the locking member 10. A head portion 22 is formed at the end of the locking portion 20. The base of the locking portion 20, that is, the vicinity of the coupling portion with the general surface 23 of the locking portion 20 is formed in a tapered shape, and the strength of the locking portion 20 is ensured. Reinforcing ribs 25 are appropriately set on the side surfaces of the locking portion 20 and the regulation ribs 26 and 26 ′, and the locking portion 20 is reinforced.

  The head portion 22 of the locking portion 20 includes a first convex portion 22a and a second convex portion 22b, and is formed so as to protrude in directions opposite to each other. In the up-down direction of the locking part 20 (the protruding direction of the locking part), the first convex part 22a is provided at a position higher than the second convex part 22b. The locking legs 4c and 4c 'of the metal clip 4 are formed in a shape corresponding to the shapes of the first convex portion 22a and the second convex portion 22b. Since the first convex portion 22 a and the second convex portion 22 b are formed at different heights, the locking member 10 can be easily inserted into and engaged with and fixed to the metal clip 4.

  The protrusion amount of the second protrusion 22b is designed to be larger than the protrusion amount of the first protrusion 22a. When engaging the locking member 10 with the metal clip 4, first, the first protrusion 22a with a small protrusion is locked to the locking leg 4c, and then the second protrusion 22b with a large protrusion is inserted. Lock to the locking leg 4c '. As a result, the required pushing force is reduced, and at the same time, the engagement force necessary for the engagement between the metal clip 4 and the locking member 10 is maintained.

  As shown in FIG. 2, the locking member 10 is bonded and fixed to the roof lining 1 so that the second convex portion 22b faces the outside of the vehicle body. Thereby, since the locking member 10 can effectively counter the force received in the rolling direction of the end of the roof lining 1, the engagement between the metal clip 4 and the locking member 10 is caused by an unexpected external force. It is prevented from being released.

  In the main portion 11 of the locking member 10, the surface 12 opposite to the side where the locking portion 20 is formed is an adhesive surface, but the flange portions 21, 21 ′ extend the main portion 11. It is provided to enlarge the adhesion surface and increase the adhesion force of the locking member 10.

  FIG. 4 is an enlarged top view of the flange portion 21 of the locking member 10, and FIG. 5 is an enlarged cross-sectional view of the flange portion showing a state in which the locking member 10 is bonded to the base material la of the roof lining 1. Hereinafter, although the flange portion 21 will be described, the same description applies to the flange portion 21 ′.

  The flange portion 21 has a through hole 27 that penetrates the flange portion 21 between the first surface 13 and the second surface 14, and the through hole 27 crosses the through hole in the in-plane direction of the flange portion 21. A bridging portion 28 is provided. The bridging portion 28 is formed so as to extend in a bridging manner from one edge of the opening edge of the through hole 27 to the other opposite edge.

  When the locking member 10 is bonded and fixed to the roof lining 1, the adhesive 29 is applied to the bonding position of the base material la of the roof lining 1, and then the locking member 10 is pressed against the adhesive 29. As a result, the back surface 12 of the main portion 11 and the second surface 14 of the flange portion 21 are bonded to the base material la via the adhesive 29. Since the through hole 27 penetrating in the thickness direction of the flange portion 21 is formed in the flange portion 21, the adhesive 29 is filled in the through hole 27. As a result, an anchor effect is added and the adhesive force is increased. In particular, in the present embodiment, since the bridging portion 28 is provided in the through hole 27, the adhesive 29 filled in the through hole 27 reaches the upper surface 28 b of the bridging portion 28, and the adhesive 29 is attached to the bridging portion 27. Bonded in a wrapped state. As a result, the anchor effect by the bridging portion 27 is added, and the locking member 10 is more firmly bonded and fixed.

  The bridge portion 28 is designed so that the bottom surface 28a facing the interior material (roof lining 1) is substantially flush with the second surface 14 of the flange portion. As a result, the resin amount of the adhesive 29 may be a minimum amount necessary for the adhesive 29 to reach the upper surface 28b of the bridging portion 28. Therefore, the adhesive 29 is insufficient due to variations in the amount of the adhesive 29 applied. Thus, it is possible to prevent as much as possible the occurrence of problems such as not reaching the upper surface 28b of the bridging portion 28.

  The thickness t of the bridging portion 28 is formed to be smaller than the thickness T of the flange portion 21. With this configuration, the adhesive 29 can reach the upper surface 28b of the bridging portion 28 more reliably. The plate thickness t of the bridging portion 28 is preferably formed so as to be included in a range of 20 to 70% of the plate thickness T of the flange portion 21, and more preferably included in a range of 40 to 50%. If it is not less than the above lower limit value, the strength of the bridging portion 28 is ensured, and cracking and deformation of the bridging portion 28 can be prevented. If it is not more than the above upper limit value, the adhesive 29 reaches the upper surface 28b of the bridging portion 28. It becomes easy.

  The through-hole 27 is connected to the constant cross section 31 and the constant cross section 31 extending in a constant cross section from the second surface 14 to a position h at a midway height in the plate thickness direction of the flange portion 21 before the first surface 13. The tapered portion 30 extends to the first surface 13 while the cross-sectional area increases toward the first surface 13. As a result, the tapered portion 30 is formed with an inclined portion 21a. By setting it as such a shape, the anchor effect by applying the adhesive agent 29 to the inclination part 21a is added, and the adhesive force of the latching member 10 is further heightened. By providing the constant cross-sectional portion 31, an extra resin amount of the adhesive 29 for the adhesive 29 to reach the tapered portion 30 is not required, so that the adhesive 29 is more reliably connected to the tapered portion 30 and the bridging portion 28. It reaches the upper surface 28b.

  The upper surface 28 b of the bridging portion 28 is formed continuously from the lower edge of the tapered portion 30. That is, the upper surface 28 b facing the panel of the bridging portion 28 is located at the same height h as the connection portion between the constant section 31 and the tapered portion 30. By adopting such a shape, the adhesive 29 can surely reach the upper surface 28b and the tapered portion 30 of the bridging portion 28, and the anchor effect by the bridging portion 28 and the tapered portion 30 is combined and bonded. The power is further increased.

  The side surface 28 c of the bridging portion 28 is formed so as not to be inclined with respect to the plate thickness direction of the flange portion 21. That is, the side surface 28 c of the bridging portion 28 extends in parallel with the plate thickness direction of the flange portion 21. By setting it as such a shape, the adhesive agent 29 reaches | attains the upper surface 28b of the bridge | crosslinking part 28 more reliably.

  The hole diameter r of the through hole 27 is 4 mm, and the width of the bridging portion is 1 mm. The occupation ratio of the bridging portion 28 with respect to the through hole 27 (projected area viewed from the second surface 14 side) is preferably in the range of 20 to 50%, and more preferably in the range of 25 to 40%. If it is more than the said lower limit, the intensity | strength of the bridge | crosslinking part 28 will be ensured, and if it is less than the said upper limit, the filling to the inside of the through-hole 27 of the adhesive agent 29 will not be inhibited, but the upper surface of the bridge | crosslinking part 28 will be easy. Reach up to 28b.

  In the present embodiment, hot-melt O207 manufactured by Diabond Co. is used as the adhesive 29. After the hot melt is heated and melted, the adhesive 29 is applied to the setting position of the locking member 10 of the base material la of the roof lining 1, and then the locking member 10 is pressed to bond the locking member 10. The locking member 10 is fixed to the roof lining 1 by the solidification of the hot melt.

(Non-woven fabric sticking)
In a state where the locking member 10 according to the present invention is adhered and fixed to the roof lining 1, a non-woven fabric may be adhered to the base material la of the roof lining 1 so as to wrap the locking member 10. Specifically, a flat nonwoven fabric provided with a cutout corresponding to the locking portion 20 of the locking member 10 is prepared, and the non-woven fabric is inserted into the locking portion 20 so that the nonwoven fabric is a flange portion of the locking member 10. In a state where 21 is covered, at least a part of the outer periphery of the nonwoven fabric is bonded and fixed with an adhesive. By adopting such a configuration, even if the locking member 10 is peeled off from the roof lining 1, the locking member 10 can be prevented from being scattered by the nonwoven fabric.

FIG. 6 is an enlarged top view showing the flange portion 21 in the second embodiment of the locking member according to the present invention. In the present embodiment, two bridging portions 28 formed in a bridging shape from one edge of the through hole 27 to the other opposite edge are formed so as to intersect in a cross shape. That is, two bridging portions are provided and intersect each other in the through hole 27. By increasing the number of cross-linked portions, the anchor effect with the adhesive by the cross-linked portion 28 is increased, so that the adhesive force is improved.

  In the present embodiment, the bridging portion 28 is formed in a cross shape when viewed from above, but is not limited to this, and can be replaced with any shape such as a Y shape or a T shape when viewed from the top surface. .
