Description

[Technical field]

[0001] The present invention relates to a clip mounting seat. [Background technology]

[0002] Conventionally, a clip mounting seat has been used to attach a plastic panel to a counterpart object. The clip mounting seat is provided integrally on the back surface of the plastic panel. A clip is attached to the clip mounting seat. The plastic panel is attached to the counterpart object by inserting the clip attached to the clip mounting seat into a mounting hole formed in the counterpart object. Such a clip mounting seat is disclosed in, for example, Patent Document 1.

[0003] The clip mounting base of Patent Document 1 has a clipped plate that is clamped by the clip, and reinforcing plates provided on both side ends of the clipped plate. The clipped plate and one of the reinforcing plates are formed with locking grooves into which the locking protrusions of the clip are locked. The internal space of the locking groove is open in radial directions over an angle of 90 degrees between one direction in the thickness direction of the clip plate and one direction perpendicular to the thickness direction (the direction toward one of the reinforcing plates). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2008-62752 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the clip mounting seat of Patent Document 1, the reinforcing plate in which the locking groove is formed extends only on one side in the thickness direction of the clipped plate. In such a clip mounting seat, when the reinforcing plate is made to function as a contact rib that determines the relative position between the plastic panel and the object, the reinforcing plate is provided only on one side of the end of the clipped plate in the thickness direction, so that the plastic panel may not be stable when assembled to the object.

[0006] Therefore, it is conceivable to provide a reinforcing plate with a locking groove only on the base side of the locking groove, and also on the side where the locking groove is opened. However, doing so would require an increase in the number of slide molds, since the space between the pair of reinforcing plates facing each other in the direction in which the locking groove extends and the locking groove would each be undercut. This would lead to a complication of the mold structure for molding the resin panel.

[0007] An object of the present invention is to stably assemble a resin panel to a mating part without complicating the mold structure. [Means for solving the problem]

[0008] In the present invention, a method of providing the contact rib that determines the relative position between the resin panel and the mating object has been devised so that the clip mounting seat can be applied to the mating object in a well-balanced manner without increasing the undercut.

[0009] Specifically, the present invention is directed to a clip mounting base to which a clip is attached for mounting a resin panel to a counterpart, and provides the following solutions.

[0010] The first invention is a clip mounting base having a plate to be attached to the back side of the plastic panel, the plate being provided upright and sandwiching the clip, and a stop rib connected to the plate and having a tip that abuts against the object to determine the relative position between the plastic panel and the object. The plate is provided with a hook hole that penetrates the plate in the plate thickness direction and hooks the clip. The stop rib includes a first rib portion that extends from one end of the plate in the plate width direction to one side in the plate thickness direction of the plate, and a second rib portion that extends from the first rib portion along the plate width direction of the plate. The first rib portion and the second rib portion divide a space together with the plate. The hook hole and the space are open in the same direction.

[0011] The second invention is the clip mounting seat of the first invention, further comprising a dog-house shaped base provided on the rear surface of the resin panel and having one side open. The mounting plate is provided on the top surface of the base with the plate width direction facing the opening of the base. The hook hole and the space are open toward the opening.

[0012] A third invention is a clip mounting seat of the first or second invention, wherein the mounting plate extends parallel to the second rib portion or is inclined at an angle greater than 0° and less than 45° relative to the second rib portion so that the space widens from the first rib portion side toward the open side. Effect of the Invention

[0013] According to the first invention, the contact rib includes a first rib portion extending from one end of the plate to be attached in the plate thickness direction, and a second rib portion extending from the first rib portion in a direction along the plate surface of the plate to be attached, so that the second rib portion can suppress rattling of the plastic panel against the mating object. This allows the plastic panel to be stably attached to the mating object. Furthermore, the spaces partitioned by the first rib portion, the second rib portion, and the plate to be attached and the hook holes are all open in the same direction, so these spaces and the hook holes can be formed using a common slide mold. This means that even if the second rib portion is provided, there is no need to increase the slide mold, and therefore the mold structure for molding the plastic panel does not need to be complicated.

[0014] According to the second invention, since the mounting plate is provided upright on the top surface of the dog-house shaped base, the connecting portion of the base with the rear surface of the resin panel can be formed relatively thin, thereby suppressing the occurrence of sink marks on the surface of the resin panel. Also, since the direction in which the space partitioned by the first rib portion, the second rib portion and the mounting plate and the hooking hole are opened is the opening direction facing the opening of the base, these spaces and the hooking holes can be formed using the same slide mold as the mold for forming the internal space of the base.

[0015] According to the third invention, the angle between the attachment plate and the second rib portion is greater than or equal to 0° and less than 45°, so that the space partitioned by the first rib portion, the second rib portion and the attachment plate and the hanging hole can be formed using a common slide mold, while the second rib portion can effectively suppress rattling of the plastic panel relative to the opposing object.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Exemplary embodiments will now be described in detail with reference to the accompanying drawings.

[0018] In this embodiment 1, a clip mounting seat according to the present invention will be described using a center panel for an automobile as an example.

[0019] The center panel 1 is an interior part of a center cluster that is located in the center of an instrument panel. The center panel 1 is an example of a resin panel. The center panel 1 is made of synthetic resin such as ABS (Acrylonitrile Butadiene Styrene) resin, and is formed, for example, by injection molding. As shown in FIG. 1, the center panel 1 has a plurality of openings 3 formed therein for installing an audio head unit, air conditioner switches, etc.

[0020] A plurality of clip mounting seats 11 are integrally provided on the back surface of the center panel 1. The clip mounting seats 11 are arranged at intervals along the outer edge of the center panel 1. For example, three clip mounting seats 11 are arranged along each of the upper and lower sides of the center panel 1. Furthermore, two clip mounting seats 11 are arranged along each of the left and right sides of the center panel 1.

[0021] The multiple clip mounting seats 11 are used to assemble the center panel 1 to an instrument panel main body (hereinafter referred to as the instrument panel main body) 101. The instrument panel main body 101 is an example of a mating object. The multiple clip mounting seats 11 include a first mounting seat 12 and a second mounting seat 15. In the portion along the upper and lower sides of the center panel 1, the clip mounting seat 11 located in the middle of the three clip mounting seats 11 is the second mounting seat 15. Of the multiple clip mounting seats 11, the clip mounting seats 11 other than the second mounting seat 15 are the first mounting seats 13.

[0022] The first mounting seats 13 are clip mounting seats 11 according to the present invention. Each of the first mounting seats 13 arranged along the upper and lower sides of the center panel 1 is shaped so that the sliding direction of a slide mold 201 used for molding faces inward in the left-right direction of the center panel 1. Each of the first mounting seats 13 arranged along the left and right sides of the center panel 1 is shaped so that the sliding direction of a slide mold 201 used for molding faces upward in the center panel 1.

[0023] As shown in Figs. 2 to 4, the first mounting seat 13 has a base 21, a mounting plate 31, and a contact rib 41. The base 21 is provided on the back surface of the center panel 1. The mounting plate 31 and the contact rib 41 are both provided integrally on the back surface of the center panel 1 and stand upright on the base 21. The base 21 is formed in a dog-house shape with one side open.

[0024] The base 21 is composed of a top surface portion 23 and a peripheral wall portion 25. The top surface portion 23 is formed in a trapezoidal shape in a plan view. The peripheral wall portion 25 extends from the periphery of three sides of the top surface portion 23 excluding the long side to the back surface of the center panel 1. The connection portion of the peripheral wall portion 25 with the back surface of the center panel 1 is formed to be relatively thin. The internal space Si of the base 21 is opened from an opening 27 formed in a portion corresponding to the long side of the top surface portion 23.

[0025] The mounting plate 31 is a plate body to which the clip 61 is sandwiched and attached. The mounting plate 31 is disposed between the long side and the short side of the top surface portion 23 of the base 21, and extends in a direction perpendicular to both sides. The mounting plate 31 is provided on the top surface portion 23 of the base 21 with its plate width direction facing the opening direction Da in which the opening 27 of the base 21 faces. Here, the opening direction Da is a direction corresponding to the sliding direction of the slide mold 201 used to mold the first mounting seat 13.

[0026] A hook hole 33 is formed in the middle of the mounting plate 31 in the height direction. The hook hole 33 is a slit-shaped opening extending in the width direction of the mounting plate 31. The hook hole 33 penetrates the mounting plate 31 in the thickness direction. The hook hole 33 is a hole for hooking the clip 61. The hook hole 33 opens in the opening direction Da of the base 21. The hook hole 33 widens slightly toward the open side.

[0027] The contact rib 41 is provided in a state where it is connected to the mounting plate 31. The tip of the contact rib 41 abuts against the instrument panel body 101 when the center panel 1 is assembled to the instrument panel body 101 (see Figures 6, 9 and 10). In this way, the contact rib 41 determines the relative position between the center panel 1 and the instrument panel body 101. The contact rib 41 is provided so as to form a y-shape in a plan view when viewed together with the mounting plate 31. The contact rib 41 includes a first rib portion 43, a second rib portion 45, a third rib portion 47 and a fourth rib portion 49.

[0028] The first rib portion 43 extends from one end of the attached plate 31 in the plate width direction, specifically, from an end located opposite the opening 27 of the base 21, to one side (upper side in FIG. 2) in the plate thickness direction of the attached plate 31. The second rib portion 45 extends from an end of the first rib portion 43 located opposite the attached plate 31 along the plate width direction of the attached plate 31. The first rib portion 43 and the second rib portion 45, together with the attached plate 31, partition the first space S1.

[0029] This first space S1 opens in the same direction as the hook hole 33, that is, toward the opening direction Da. The second rib portion 45 is inclined with respect to the attachment plate 31 so that the first space S1 widens from the first rib portion 43 side toward the opening side. The angle α that the extension direction of the second rib portion 45 (direction along the two-dot chain line in FIG. 2) and the extension direction of the attachment plate 31 (direction along the one-dot chain line in FIG. 2) make toward the opening 27 of the base 21 is, for example, an angle greater than 0° and equal to or less than 45°.

[0030] The angle α is preferably 0.5° or more. If the angle α is less than 0.5°, the slide mold 201 may have difficulty sliding. If the angle α is greater than 45°, the first mounting seat 13 becomes too large, limiting the installation location of the first mounting seat 13. In this example, the angle α is set to 3°. The second rib portion 45 may extend parallel to the mounting plate 31.

[0031] The third rib portion 47 extends from one end of the attached plate 31 in the plate width direction to which the first rib portion 43 is connected to the other side (lower side in FIG. 2) in the plate thickness direction of the attached plate 31. The third rib portion 47 is provided symmetrically to the first rib portion 43 across the attached plate 31. The fourth rib portion 49 extends in the same direction as the third rib portion 47 from an end of the attached plate 31 located on the opening 27 side of the base 21 in the plate width direction. The third rib portion 47 and the fourth rib portion 49, together with the attached plate 31, partition the second space S2.

[0032] The internal space Si of the base 21, the first space S1, and the hook hole 33 are provided by using a common slide mold 201 (see FIG. 4) when the center panel 1 is molded. The slide mold 201 is composed of a first mold part 203 and a second mold part 205. The first mold part 203 molds the inner surface of the base 21. The second mold part 205 molds the portion of the mounting plate 31 closer to the base 21 than the hook hole 33, the surfaces of the first rib part 43 and the second rib part 45 facing the first space S1, and the inner surface of the hook hole 33. The first mold part 203 and the second mold part 205 are integral mold parts.

[0033] The multiple first mounting seats 13 include a reference mounting seat 13R. The reference mounting seat 13R determines a reference position in the up-down direction when assembling the center panel 1 to the instrument panel main body 101. For example, the first mounting seats 13 on both the left and right sides located along the upper side of the center panel 1 are set as the reference mounting seats 13R. A reinforcing rib 51 is provided at the end of the attachment plate 31 to which the first rib portion 43 and the third rib portion 47 are connected. The reinforcing rib 51 protrudes on both sides of the attachment plate 31 in the plate thickness direction.

[0034] The protruding length of the reinforcing rib 51 differs between the reference mounting seat 13R and the first mounting seats 13 other than the reference mounting seat 13R. Specifically, the protruding length of the reinforcing rib 51 of the reference mounting seat 13R is longer than the protruding length of the reinforcing rib 51 of the first mounting seats 13 other than the reference mounting seat 13R. When the reinforcing rib 51 of the reference mounting seat 13R is inserted into a mounting hole 103 formed in the instrument panel main body 101, it is fitted into the mounting hole 103 in the vertical direction. When the reinforcing rib 51 of the first mounting seat 13 other than the reference mounting seat 13R is inserted into the mounting hole 103, it is fitted into the mounting hole 103 with a gap.

[0035] The second mounting seats 15 are clip mounting seats 11 having a different configuration from the first mounting seats 13. Each second mounting seat 15 constitutes a reference mounting seat 15R. This reference mounting seat 15R determines a reference position in the left-right direction when assembling the center panel 1 to the instrument panel main body 101. The reference mounting seat 15R may be constituted by any one of the second mounting seats 15. The second mounting seat 15 has a base 21, an attachment plate 31, a contact rib 41, and a reinforcing rib (not shown).

[0036] The base 21 of the second mounting seat 15 is formed in a dog-house shape similar to the base 21 of the first mounting seat 13. A slit-shaped hook hole is formed in the mounting plate 31 of the second mounting seat 15. The hook hole is not open to the side in the plate width direction of the mounting plate 31. The contact rib 41 is provided so as to form an H-shape in a plan view when viewed together with the mounting plate 31. The reinforcing rib of the second mounting seat 15 is formed so as to be fitted snugly into the mounting hole 103 in the left-right direction.

[0037] As shown in Figs. 5 to 8, a clip 61 is attached to the first mounting seat 13. The clip is made of synthetic resin. A clip 61 is also attached to the second mounting seat 15. The clip 61 is attached by covering the mounting plate 31 of the clip mounting seat 11. The clip 61 has a pair of first clip pieces 65 and a pair of second clip pieces 69. The pair of first clip pieces 65 and the pair of second clip pieces 69 are each flexible.

[0038] The pair of first clip pieces 65 can be spread apart from each other. The opposing portions of the pair of first clip pieces 65 are provided with latching claws 67. When the pair of first clip pieces 65 are spread apart, they are biased by the elastic force of the clip 61 to return in a direction approaching each other. The pair of second clip pieces 69 are provided on both sides of the pair of first clip pieces 65.

[0039] The pair of second clip pieces 69 are formed to provide a gap between them and the mounting plate 31 when the clip 61 is attached to the mounting plate 31 and not inserted into the mounting hole 103 of the instrument panel body 101. The pair of second clip pieces 69 can be narrowed in a direction in which they approach each other. When narrowed, the pair of second clip pieces 69 are urged by the elastic force of the clip 61 to return in a direction in which they move away from each other.

[0040] When assembling the center panel 1 to the instrument panel main body 101, first, the clips 61 are attached to the mounting plates 31 of the clip mounting seats 11 (the first mounting seat 13 and the second mounting seat 15). At this time, as shown in Fig. 7, the latching claws 67 are inserted into the latching holes 33. As a result, the clips 61 are latched to the mounting plate 31. Then, as shown in Figs. 9 and 10, the clips 61 attached to the clip mounting seats 11 are inserted into the corresponding mounting holes 103 of the instrument panel main body 101.

[0041] When each clip 61 is inserted into the mounting hole 103 of the instrument panel main body 101, the pair of second clip pieces 69 spreads inside the mounting hole 103 and presses against the periphery of the mounting hole 103. This prevents each clip 61 from slipping out of the mounting hole 103 of the instrument panel main body 101. When the center panel 1 is attached to the instrument panel main body 101 in this manner, the contact rib 41 abuts against the instrument panel main body 101 as shown in Fig. 11. In the instrument panel main body 101, the first rib portion 43 and the second rib portion 45 abut against one side of the mounting hole 103 (the left side in Fig. 11), and the third rib portion 47 and the fourth rib portion 49 abut against the other side of the mounting hole 103 (the right side in Fig. 11).

[0042] -Features of the embodiment- According to the first mounting seat 13 of this embodiment, the center panel 1 can be stably assembled to the instrument panel body 101 without complicating the mold structure.

[0043] 12 and 13, if the clip mounting seat 11 does not have the second rib portion 45, when the center panel 1 is assembled to the instrument panel body 101, the contact point of the contact rib 41 against the instrument panel body 101 becomes unbalanced in the plate width direction of the mounting plate 31 as shown in Fig. 14. Therefore, there is a risk that the center panel 1 may not be stable when assembled to the instrument panel body 101.

[0044] In contrast, in the first mounting seat 13 of this embodiment, the contact rib 41 includes, in addition to the first rib portion 43 extending from one end of the mounted plate 31 in the plate thickness direction, a second rib portion 45 extending from the first rib portion 43 in the plate width direction of the mounted plate 31. The second rib portion 45 can suppress rattling of the center panel 1 relative to the instrument panel main body 101. This allows the center panel 1 to be stably assembled to the instrument panel main body 101.

[0045] The first space S1 and the hook holes 33, which are partitioned by the first rib portion 43, the second rib portion 45, and the mounting plate 31, are open in the same direction. The first space S1 and the hook holes 33 can be formed using a common slide die 201. As a result, even if the second rib portion 45 is provided, there is no need to increase the number of slide dies 201, and therefore the mold structure for molding the center panel 1 does not need to be complicated.

[0046] In the clip mounting base 11 of this embodiment, the mounting plate 31 is provided upright on the top surface 23 of the dog-house shaped base 21. The connection portion of the base 21 with the rear surface of the center panel 1 is formed relatively thin, so that the occurrence of sink marks on the surface of the center panel 1 can be suppressed.

[0047] The direction in which the first space S1 partitioned by the first rib portion 43, the second rib portion 45, and the mounting plate 31 and the hook hole 33 are opened is the opening direction Da in which the opening 27 of the base 21 faces. The first space S1 and the hook hole 33 can be formed by using a slide mold 201 that is the same as the mold for forming the internal space Si of the base 21.

[0048] In the clip mounting seat 11 of this embodiment, the angle α between the mounting plate 31 and the second rib portion 45 is equal to or larger than 0° and equal to or smaller than 45°. This makes it possible to form the first space S1 partitioned by the first rib portion 43, the second rib portion 45, and the mounting plate 31 and the hook hole 33 using the common slide mold 201, while the second rib portion 45 can suitably suppress rattling of the center panel 1 relative to the instrument panel main body 101.

[0049] As described above, a preferred embodiment has been described as an example of the present invention. However, the present invention is not limited to this, and can be applied to embodiments in which appropriate changes, substitutions, additions, omissions, etc. are made. It will be understood by those skilled in the art that various further modifications are possible in the above embodiment, and that such modifications also fall within the scope of the present invention.

[0050] For example, the first mounting seat 13 does not have to have the base 21. The configuration in which the first mounting seat 13 has the base 21 is merely one example. The same applies to the second mounting seat 15. In short, it is sufficient that the first mounting seat 13 is provided with the second rib portion 45, and that the latch hole 33 and the first space S1 are open in the same direction.

[0051] The clip mounting seat 11 (first mounting seat 13) according to the present invention can also be applied to the assembly of other automotive interior panels, such as various body side trims such as front pillar garnishes, door trims, etc. The clip mounting seat 11 (first mounting seat 13) can also be applied to resin panels used for purposes other than automobiles.
