  The present invention relates to a manufacturing jig for vehicle interior parts.

  2. Description of the Related Art Conventionally, an interior component that includes a base material and a flexure member that protrudes toward the base material and has a plurality of projections that can be flexibly deformed is well known. In the interior part of Patent Document 1, when the bending member is pushed toward the base material, some or all of the plurality of protrusions come into contact with the base material and bend and deform. By the bending deformation, the user can obtain a soft tactile sensation when contacting the interior part.

WO2013 / 132676

  In order to improve the appearance quality, a film-like skin material may be laminated and bonded to the flexible member. Affixing requires pressure to bond the flexible member and the skin material together. However, since the bending member bends and deforms due to pressure, adhesion failure between the bending member and the skin material is likely to occur.

  The objective of this invention is providing the manufacturing jig of the interior component for vehicles which suppresses the adhesion defect of a bending member and a skin material.

  In order to solve the above-described problems, a base material, a plate portion stacked on the base material, and a projection provided on the plate portion, and when the plate portion approaches the base material, An interior part for a vehicle comprising: a bending member having a protrusion that bends and deforms so as to fall by contacting while moving; and a skin material that is attached to the plate portion opposite to the surface on which the protrusion is provided. The manufacturing jig is disposed on the pedestal so as to avoid the protrusion and to contact the plate portion, and follows the displacement of the plate portion as the protrusion deforms. The gist of the present invention is to include a deforming portion that deforms as described above.

  According to this structure, the board part which comprises a bending member is supported by a manufacturing jig with a protrusion and a deformation | transformation part. That is, the number of portions supported by the plate portion is increased by the amount of the deformable portion. In addition, when the skin material is pressed against the bending member to attach the skin material to the bending member, the deformation portion follows the displacement of the plate portion when the projection is deflected and deformed due to the pressure accompanying the pressing. Deform to By these, since the pressure accompanying adhesion | attachment with a bending member and a skin material is hard to concentrate on the specific location of a board part, the bending deformation in a board part is suppressed. Therefore, poor adhesion between the bending member and the skin material is suppressed.

The said structure WHEREIN: It is preferable that the said deformation | transformation part is equipped with a supporting member and the elastic member interposed between the said supporting member and the said base.
According to this configuration, since the deforming portion is configured with a simple configuration of the support member and the elastic member, it is easy to maintain and adjust the manufacturing jig.

The said structure WHEREIN: It is preferable that the said processus | protrusion is arrange | positioned at polygonal grid | lattice form, and the said deformation | transformation part is provided so that it may correspond to the center part of the said processus | protrusions arrange | positioned at the said polygonal grid | lattice form.
According to this configuration, since the position where the plate portion is easily bent is supported by the deformation portion, the deformation of the bending member when the skin material is attached is suppressed as compared with the case where the deformation portion is provided at another position. The

In the above configuration, it is preferable that the protrusions are arranged in a row to form a plurality of protrusion rows, and the deforming portion is arranged in a row between the protrusion rows.
When a bending member is manufactured using a split mold, it is well known that a dividing line is provided on the bending member. It is also well known that it is difficult to provide a protrusion near the parting line. Therefore, protrusions may be arranged in rows on both sides of the parting line to form protrusion rows.

  According to this configuration, the deforming portions are arranged in rows between the projection rows. Thereby, since the position which is easy to bend in the board part between projection rows is supported by the line-shaped deformation part, compared with the case where the deformation part is provided at another position, the bending member when the skin material is attached Bending deformation is suppressed.

  The vehicle interior part manufacturing jig according to the present invention has an effect of suppressing poor adhesion between the bending member and the skin material.

Hereinafter, one embodiment of a manufacturing jig for interior parts for vehicles will be described with reference to the drawings.
As shown in FIG. 1, the vehicle interior part 10 constitutes a part of a vehicle door trim.
As shown in FIG. 2, the vehicle interior component 10 includes a plate-like base material 11, a flexure member 12 superimposed on the base material 11, a superposition on the flexure member 12, and a vehicle interior side. And an exposed skin material 13.

The base material 11 is made of a synthetic resin material such as polypropylene, and forms the basic skeleton of the laminated composite interior part.
The flexible member 12 is made of a synthetic resin material that is relatively soft and elastically deformable, such as soft polyvinyl chloride.

  As shown in FIGS. 2, 3, and 5, the bending member 12 includes a plate portion 20 that is shaped to extend along the base material 11 and has a plate thickness dimension T, and a base of the plate portion 20. And a large number of protrusions 21 protruding from the surface facing the material 11.

  The protrusion 21 has a rectangular bottom pyramid shape at the base end 21a, and an oblique quadrangular pyramid extending in a direction inclined by an inclination angle α with respect to a normal line O extending in a direction perpendicular to the surface of the flexible member 12 on the substrate 11 side. Body, all corners are rounded. The tip 21b of the protrusion 21 is in contact with the base material 11. 4A and 4B, the protrusions 21 form a so-called honeycomb structure in which regular hexagons continue in cooperation with the adjacent protrusions 21, and the adjacent protrusions 21 are mutually connected. They are arranged side by side so as to bend and deform toward the center of different regular hexagons.

  When the base material 11 and the plate portion 20 are close to each other, the protrusion 21 is deformed by bending (elastically deforming) toward the bending direction A in which the inclination angle α is increased by contacting the base material 11 while sliding. . In other words, the protrusion 21 has anisotropy in bending deformation.

  As shown in FIGS. 2 and 5, the skin material 13 is a synthetic resin material that is relatively hard and can be elastically deformed, such as PVC (polyvinyl chloride) and elastomer. The skin material 13 is in the form of a film having a thickness dimension t smaller than the thickness dimension T of the bending member 12 (plate portion 20). The skin material 13 is bonded to the bending member 12 using a manufacturing jig 30 described later.

  Therefore, in the vehicle interior component 10, the color, pattern, luster, and the like can be changed simply by changing the skin material 13 to be attached to the flexible member 12 to a desired one. Thus, the appearance quality of the vehicle interior part 10 can be improved more easily than adjusting the color, pattern, gloss, etc. of the bending member 12.

Next, the manufacturing jig 30 for the vehicle interior part 10 will be described.
As shown in FIGS. 6 and 7, the manufacturing jig 30 includes a pedestal 31, a coil spring 32, and a support member 33.

  The pedestal 31 is a housing recess that is recessed at a position on the surface of the pedestal 31 that avoids the protrusion 21 of the flexible member 12 that is superimposed on the pedestal 31, more precisely at a position that corresponds to the central portion of the honeycomb structure in which regular hexagons continue. 34 is provided. The pedestal 31 has the same shape as the base material 11 except for an accommodation recess 34 described later.

A support member 33 is housed in the housing recess 34 with the coil spring 32 interposed between the housing recess 34 and the bottom of the housing recess 34.
The support member 33 is a cylindrical shaft having an axial dimension that is longer than the protruding amount of the protrusion 21 and longer than the recessed amount of the housing recess 34. One end 33 a of the support member 33 is in contact with the coil spring 32, and the other end 33 b is housed in the housing recess 34 in a state of protruding from the housing recess 34.

Each dimension of the support member 33 and the coil spring 32 is set so that the length of the portion of the support member 33 that protrudes from the housing recess 34 is equal to the protrusion amount of the protrusion 21.
Next, the operation and effect of the manufacturing jig 30 for the vehicle interior part 10 will be described.

  As shown in FIG. 7, the bending member 12 is set on the manufacturing jig 30. At this time, the tip 21 b of the protrusion 21 contacts the pedestal 31 of the manufacturing jig 30, and the end 33 b of the support member 33 contacts the plate 20 of the bending member 12.

  Next, as shown in FIG. 8, the skin material 13 is applied in a state where an adhesive is applied to the surface of the plate portion 20 on the skin material 13 side, the surface of the skin material 13 on the flexible member 12 side, or both. The skin material 13 is pressed against the bending member 12 while being superposed on the bending member 12. Thereby, the pressure toward the manufacturing jig 30 is applied to the skin material 13 and the bending member 12. Due to the pressure, the protrusion 21 is bent and deformed, and the coil spring 32 is elastically deformed. It is desirable that the elastic modulus of the coil spring 32 is set so that the amount of deformation of the protrusion 21 is equal to the amount of elastic compression deformation of the coil spring 32.

  Thus, the base end portion 21a of the protrusion 21 has an elastic force accompanying the deformation of the protrusion 21, and the central portion of the honeycomb structure where the protrusion 21 is not provided has an elastic force accompanying the elastic compression deformation of the coil spring 32. Each.

  Therefore, as shown in comparison between FIG. 8 and FIG. 12, if the manufacturing jig 30 of this example is adopted, the manufacturing jig 120 shown as a comparative example that does not employ the coil spring 32 and the support member 33 (see FIG. 12). ) To support the plate part 20 through more points. That is, the elastic force that balances the pressure acts on the plate portion 20 through more places, so that the elastic force is uniformly applied by the plate portion 20. For this reason, when the skin material 13 is pressed against the bending member 12, the plate portion 20 is not easily bent.

  As a result, as shown in FIG. 9, if the pressing of the skin material 13 against the bending member 12 is eliminated, the protrusion 21 and the coil spring 32 are elastically restored, and the bonding between the bending member 12 and the skin material 13 is performed. Complete.

  In addition, as shown in FIG. 5, the vehicle interior part 10 is manufactured by removing the flexure member 12 and the skin material 13 that have been bonded and integrated from the manufacturing jig 30 and attaching them to the base material 11.

Thus, since the board part 20 and the skin material 13 are adhere | attached in the state in which the bending deformation of the board part 20 was suppressed, the adhesion failure of the bending member 12 and the skin material 13 is suppressed.
In addition, when employ | adopting the manufacturing procedure which affixes the film-form skin material 13 to the bending member 12 using the manufacturing jig 30, the bending member 12 to which the bending deformation was suppressed is applied to the skin material 13 which has not been given a shape. It can affix on the flexible member 12, deform | transforming so that it may follow. That is, since the shaping to the skin material 13 and the adhesion between the skin material 13 and the bending member 12 can be performed in the same process, it is effective in reducing the number of manufacturing steps of the vehicle interior part 10.

  Moreover, the simple structure of the coil spring 32 and the support member 33 was employ | adopted as a deformation | transformation part. Thereby, the maintenance of the manufacturing jig 30 is possible only by exchanging the coil spring 32 and the support member 33. Further, the coil spring 32 can be replaced with a coil spring 32 having a different elastic modulus according to the shape and inclination of the protrusion 21 and the flexibility of the bending member 12 itself. That is, the adjustment of the manufacturing jig 30 for suppressing the bending deformation of the plate portion 20 is easy.

In addition, you may change the said embodiment as follows.
In the above embodiment, the bending member 12 may be formed using a plurality of split dies. In this case, as shown in FIG. 10, the bending member 12 has a parting line L corresponding to the boundary of the split mold. The parting line L in this example is a straight line, but it is not necessarily a straight line and may have a curved portion.

Here, it is well known that the protrusions 21 cannot be arranged in the vicinity of the parting line L so that the honeycomb structure is continuous as in the above embodiment.
Therefore, the protrusions 21 in the vicinity of the parting line L may be arranged so as to be parallel to the parting line L to form the protrusion row PL. Here, it is assumed that the protrusion rows PL are formed on both sides of the parting line L. In addition, although the protrusion row PL in this example is shared with one side of the honeycomb structure, it is not necessarily required to be shared. It can be appropriately changed according to the protrusion length of the protrusion 21.

Thus, when the bending member 12 has the parting line L, since the protrusion 21 is not provided in the vicinity of the parting line L, more precisely between the protrusion rows PL, it is easy to bend and deform.
Therefore, as shown in FIG. 11, the pedestal 31 of the manufacturing jig 30 is along the same parting line L corresponding to the parting line L of the bending member 12 overlaid on the pedestal 31 in the surface. A rectangular groove 35 that is recessed to extend is provided. In addition, the recessed amount of the rectangular groove 35 is set to be equal to the accommodation recessed portion 34 of the above embodiment.

Further, the manufacturing jig 30 includes a support member 36 accommodated in the rectangular groove 35.
The support member 36 is a rectangular column extending along the parting line L like the rectangular groove 35, and the dimension of the rectangular groove 35 in the recessed direction is equal to the axial dimension of the support member 33 of the above embodiment. Is set to A coil spring 32 (not shown) is interposed between the support member 36 and the rectangular groove 35. Therefore, the support member 36 protrudes from the rectangular groove 35 so as to be equal to the protrusion amount of the support member 33 of the above embodiment, that is, equal to the protrusion amount of the protrusion 21.

  If comprised in this way, when the bending member 12 is set to the manufacturing jig 30, the position where it is easy to bend in the board part 20 between protrusion row | line | column PL will be along the dividing line L, ie, along the protrusion row | line PL. Is supported by a support member 36 extending in the direction. Therefore, when the skin material 13 is to be bonded to the bending member 12, an elastic force that balances the pressure acts on the plate portion 20, so that the plate portion 20 is not easily bent. Thus, since the board part 20 and the skin material 13 are adhere | attached in the state in which the bending deformation of the board part 20 was suppressed, the adhesion failure of the bending member 12 and the skin material 13 is suppressed.

The support member 36 may be changed to a coil spring 32 and a support member 33 that are arranged in a plurality of rows.
-In above-mentioned embodiment, although the deformation | transformation part was comprised by the coil spring 32 and the supporting member 33, the structure of those other than this may be sufficient.

  For example, the coil spring 32 may be changed to another elastic member such as another spring or a rubber material. Further, the coil spring 32 may be changed to a hydraulic pressure or the like. Further, the coil spring 32 may use a repulsive force of a magnet.

  The support member 33 is not limited to a cylindrical shape. The shape may be changed as appropriate. However, it is desirable that the portion in contact with the bending member 12 (the end portion 33b in the above embodiment) has a surface shape that can be brought into surface contact with the plate portion 20 from the viewpoint of suppressing the bending deformation of the bending member 12. .

In the above embodiment, the setting positions of the coil spring 32 and the support member 33 are not limited to the central part of the honeycomb structure in which regular hexagons are continuous, and may be any positions that do not contact the protrusions 21.
In the above embodiment, the inclination angle of the protrusion 21 may be adjusted as appropriate.

  In the above embodiment, the plurality of protrusions 21 are arranged in a lattice shape (honeycomb structure in which regular hexagonal shapes are continuous) with a predetermined interval, thereby obtaining a uniform tactile sensation. It is not necessarily limited to a lattice shape.

  -In above-mentioned embodiment, although the vehicle interior component 10 comprised a part of door trim for vehicles, it may be applied to another part. For example, you may apply to a luggage side trim, an instrument panel, an armrest, etc. Moreover, you may apply not only to a vehicle but to panel components other than for vehicles.

  In the above embodiment, the base material 11 may employ a relatively hard synthetic resin material such as hard polyvinyl chloride, polypropylene, polyethylene, or ABS. The flexible member 12 may employ various thermoplastic resins such as soft polyvinyl chloride, styrene, olefin, and polyester.

  In the above embodiment, the protrusion 21 is an inclined quadrangular pyramid and the bending direction A is limited. However, the protrusion may have various shapes as long as the bending direction is limited. For example, in the case of an oblique cone, the bending direction is limited, so that it can be employed instead of the protrusion 21 regardless of the shape of the base end. In addition, if the shape of the bottom surface of the base end is a cone with a difference between the length in one direction such as an ellipse or a rectangle and the length in the other direction orthogonal thereto, the bending direction is limited due to the relationship of the cross-sectional secondary moment Therefore, it can be employed instead of the protrusion 21.

In the above embodiment, the corners of the protrusions 21 forming the oblique quadrangular pyramid are rounded at all corners, but may not be rounded.
Next, the technical idea conceived from the embodiment and the other examples will be described.

  (A) In the above configuration, the elastic modulus of the elastic member is set so that the amount of bending deformation of the protrusion is equal to the amount of elastic compression deformation of the elastic member.
