[0013]
The skin material 14 is based on, for example, a spray molding technique illustrated in FIG. 8A by using a skin molding die (electroforming mold) 80 manufactured by the electroforming technique illustrated in FIG. 7A. It is made of urethane and is generally molded to a substantially uniform thickness of about 1 mm, and has a high degree of flexibility, and has a wrinkle pattern resembling genuine leather on the surface. . The mounting opening 18 having an inner contour shape that matches the outer contour shape of the decorative frame body 40 is formed in a substantially rectangular shape at a required position. Further, the bottom of the mounting opening 18 faces the recessed portion 24 formed in the panel base material 12, and a substantially rectangular insertion port 28 that matches the insertion port 26 is formed. Further, two sets of engaging recesses 30 in which the engaging projections 66 projecting from the decorative frame body 40 are aligned with each other on the upper / lower and left / right wall portions of the mounting opening 18. The foam 16 is formed in a state of biting into the foam 16. On the other hand, the skin of the opening periphery 20 in the mounting opening 18 Ridge The edge 22 is formed in a shape that is squared over the entire circumference, and the front end edge of the mounting opening 18 has a sharp shape with an edge.
[0014]
The skin molding die 80 manufactured to mold the skin material 14 has a skin molding surface 82 having a shape obtained by inverting the outer surface design of the instrument panel 10, and a required position of the skin molding surface 82. Further, a bulging portion 84 having an outer contour shape which is a reverse of the shape of the mounting opening 18 is provided in a protruding manner. That is, the bulging portion 84 protrudes in the same contour shape as the outer contour shape of the decorative frame body 40, and a protrusion 86 for forming the engagement recess 30 protrudes on the side surface. Further, as illustrated in FIG. 7B, a projecting piece 88 protruding so as to match the contour shape of the insertion opening 28 is extended on the upper surface of the bulging portion 84, A thin cutting line is formed at the bottom of the integrally formed mounting opening 18 (FIG. 8A). Further, the base contour edge 90 extending to the boundary portion between the bulging portion 84 and the skin molding surface 82 is formed in an angular shape that is angular as illustrated in FIG.

In FIG. 11, reference numeral 108 is a seal member for preventing leakage of the foam 16, and reference numerals 110 and 110 indicate that the decorative frame body 40 is deformed by the foaming pressure applied through the skin material 14. It is a shape holding member for preventing.
[0017]
The decorative frame body 40 constituting the air outlet AL is a resin molded member obtained by injection-molding an olefin resin material such as polypropylene using a molding die (not shown), as illustrated in FIGS. A cylindrical main body 46 formed in a substantially rectangular cylindrical shape and accommodated inside the mounting opening 18, and a front panel 48 formed in a substantially rectangular frame shape and exposed to the front side of the mounting opening 18. It has a structure that is integrally molded. The air outlet AL of the embodiment has a unit structure in which a wind direction control plate 50 composed of vertical fins and / or horizontal fins and an air volume dial 52 for air volume adjustment are assembled in the cylindrical main body 46 of the decorative frame body 40. In other words, the duct D is disposed inside and outside the tip. For this reason, the decorative frame body 40 can be detached and attached to the mounting opening 18 alone. By facing the duct D into the cylindrical main body 46, the wind direction control plate 50 and The air volume dial 52 faces the air outlet 54 and the operation port 56 formed in the front panel portion 48, respectively.
[0018]
The cylindrical main body 46 has a first space 60 in which the front end of the duct D enters and aligns with a partition wall 58 formed so as to extend vertically, and a second space that aligns with the air volume dial 52. It is partitioned into a space 62. In addition, each outer peripheral wall 64 forming the cylindrical main body portion 46 is set to have a thickness of 1 mm or less at any portion, and is bent in the thickness direction (the first space 60 or the second space 62 side). The elastic deformation is formed relatively easily. In addition, two sets of engaging projections 66 project from each outer peripheral wall (upper surface, lower surface, left side surface, and right side surface) 64. Each engaging convex portion 66 is composed of a plurality (three in the embodiment) of rib pieces 68, and is directed to the mounting direction (rear side) of the decorative frame body 40 with respect to the mounting opening 18. It has the inclined surface 70 and the 2nd inclined surface 72 which faced the removal direction (front side) of the said decoration frame 40 with respect to this attachment opening part 18, and the shape seen from the side is a substantially triangle. .
[0019]
The front panel portion 48 is set to be slightly larger than the cylindrical main body portion 46, extends from the outer peripheral surface of the cylindrical main body portion 46 by about 2 to 3 mm, and forms an outer edge of the outer peripheral edge. The shape / size of 42 is the same as the opening shape / size of the opening periphery 20 of the mounting opening 18. As shown in FIGS. 2 to 4, when the decorative frame body 40 is attached to the attachment opening 18, the part of the outer peripheral edge 42 that faces the front side from the attachment opening 18. Ridge The edge portion 44 is formed in a shape that does not adhere to the opening peripheral edge 20 of the mounting opening 18. Specifically said parts Ridge The edge portion 44 is formed in a stepped shape as a result of extending a recessed corner portion having a required width and a required depth along the outer peripheral edge 42.
[0020]
Each of the engagement recesses 30 described above is formed in a shape that matches the shape of the corresponding engagement protrusion 66, and the first inclination that matches the first inclined surface 70 of the engagement protrusion 66. It has a receiving surface 32 and a second inclined receiving surface 34 that matches the second inclined surface 72. Since each engaging recess 30 is in a state of protruding into the foam 16 as described above, the shape is maintained with the elasticity of the foam 16. Moreover, in the component mounting structure of the embodiment, as described above, the foam 16 is foam-molded between the skin material 14 and the panel substrate 12 with the decorative frame body 40 set in the mounting opening 18. The foaming pressure generated during the foam molding of the foam 16 is applied to the mounting opening 18 over the entire surface, and each of the engaging projections 66 corresponds to each of the engaging recesses 30. The attachment opening 18 and the decorative frame body 40 come into close contact with each other substantially while engaging closely.
[0021]
In addition, due to the elastic deformation of the cylindrical main body 46 of the decorative frame body 40 and the elastic deformation of the attachment opening 18 and the engagement recess 30, each of the engagement protrusions 66 and the corresponding engagement recess 30. As shown in FIG. 5, the decorative frame body 40 can be attached to and detached from the mounting opening 18. For example, when the decorative frame body 40 attached to the attachment opening 18 is removed, the decorative frame body 40 is instrumented while gripping the inner peripheral edge of the air outlet 54 in the front panel portion 48. If it is pulled strongly toward the front side of the panel 10, removal is permitted by elastic deformation of the mounting opening 18 and elastic deformation of the cylindrical main body 46. When the decorative frame 40 is attached to the attachment opening 18, the decorative frame 40 is attached to the rear side of the instrument panel 10 with the rear side of the cylindrical main body 46 aligned with the attachment opening 18. If it is pushed in strongly, the attachment is permitted by the elastic deformation of the attachment opening 18 and the elastic deformation of the cylindrical main body 46.
[0022]
Therefore, in the component mounting structure of the embodiment, the decorative frame body 40 can be attached to and detached from the mounting opening 18, so that, for example, when the wind direction control plate 50, the air volume dial 52, etc. are damaged or malfunctioned. The air outlet AL can be easily repaired or the parts can be replaced. In addition, it is possible to take out the haberdash (coins, rings, cards, etc.) that have entered the duct D from the air outlet 54, and the duct D can be cleaned and maintained.
[0023]
In the state where the decorative frame body 40 is attached to the accommodation holding position (fixed position) of the attachment opening 18, the back side portion of the opening periphery 20 of the attachment opening 18 and the outer periphery 42 of the decoration frame 40. The rear side portion of the head is closely aligned with no gap over the entire circumference. As described above, since the foam 16 is integrally foamed between the skin material 14 and the panel base 12 with the decorative frame 40 set in the mounting opening 18, the foam 16 This is because the foaming pressure generated at the time of foam molding is applied to the opening peripheral edge 20, whereby the degree of adhesion between the opening peripheral edge 20 and the outer peripheral edge 42 is increased, and a gap is formed between both peripheral edges 20, 42. It is never defined.
[0024]
However, as apparent from FIG. 11, the skin provided on the peripheral edge 20 of the opening. Ridge Since the foaming pressure of the foam 16 is hardly applied to the edge 22, the skin Ridge Edge 22 and said part Ridge The edge 44 forms a contour groove 36 having an angular cross section extending along the opening periphery 20 and the outer periphery 42. In this state, the opening peripheral edge 20 of the mounting opening 18 is exposed to the contour groove 36 and is visually recognized, and the outer peripheral edge 42 of the decorative frame body 40 is not exposed to the contour groove 36, parts Ridge Only the edge 44 is visible. The size of the contour groove 36 is the same as that of the component Ridge Although it is determined by the size of the stepped shape of the edge 44, it is desirable to set the width dimension W = 0.2 to 1.0 mm and the depth dimension S = about 0.2 to 1.0 mm. Further, the width dimension W of the contour groove 36 is substantially constant within the range of the dimension at any part.
[0025]
That is, in the component mounting structure of the embodiment, the skin that is squared around the opening periphery 20 of the mounting opening 18 provided in the skin material 14. Ridge A component that forms the edge 22 and does not adhere to the outer peripheral edge 42 of the decorative frame body 40 to the opening peripheral edge 20 Ridge By forming the edge portion 44, the contour groove 36 extending along the opening peripheral edge 20 and the outer peripheral edge 42 is formed in a state where the decorative frame body 40 is attached to the accommodation holding position of the attachment opening 18. I made it. As a result, the front surface 40A of the decorative frame body 40 and the outer surface 14A of the skin material 14 become discontinuous surfaces by the contour groove 36, and the opening peripheral edge 20 of the mounting opening 18 is visually recognized from the outside. Accordingly, the contour groove 36 causes the front surface 40A of the decorative frame body 40 and the outer surface 14A of the skin material 14 to be flush with each other. As a result, the texture of the instrument panel 10 is reduced. Can be prevented.
[0026]
In addition, the epidermis Ridge By making the edge portion 22 into an angular shape, the boundary portion between the skin material 14 and the decorative frame body 40 becomes a sharp shape, and as illustrated in FIG. 6, the presence of the air outlet AL can be emphasized. As well as being able to, design sharpness will be expressed. Moreover, the width dimension W of the contour groove 36 is substantially constant at any part. Therefore, the texture of the instrument panel 10 is prevented from being deteriorated, and the texture is preferably improved.
[0027]
