Description

[Technical field]

[0001] The present invention relates to a resin part for a vehicle, a sheet part for a vehicle interior, and a board for a vehicle interior using the same, and in particular to a resin part for a vehicle made of a synthetic resin having an uneven surface, a sheet part for a vehicle interior, and a board for a vehicle interior using the same. [Background technology]

[0002] Conventionally, resin components for vehicles of various shapes formed from synthetic resin materials have been used as exterior components constituting the exterior of vehicles such as automobiles and interior components constituting the interior of the vehicles. It is also known that synthetic resin vehicle interior sheet members or vehicle interior boards using the same are provided as floor panels or the like in seats, luggage compartments, etc. of vehicles such as automobiles. For example, Patent Document 1 discloses a vehicle interior board having a sandwich panel structure in which a foamed polyurethane layer is formed between a pair of metal plates, Patent Document 2 discloses a luggage board that closes the opening of the luggage compartment of a vehicle, and Patent Document 3 discloses a resin deck board that can be rotated around a hinge portion.

[0003] It is known that in vehicle interior sheet members or other vehicle resin members formed from synthetic resin materials used for this type of vehicle interior board, etc., fine irregularities or patterns are formed on the surface by, for example, embossing. For example, Patent Document 4 discloses a floor mat to be laid on the floor of a vehicle seat or trunk, which includes an upper sheet made of thermoplastic synthetic resin and a lower sheet made of a cushioning material joined to the upper sheet, and the surface of the upper sheet is embossed. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2019 / 026224 [Patent Document 2] JP 2021-130432 A [Patent Document 3] JP 2015-164827 A [Patent Document 4] JP 2019-93887 A Summary of the Invention [Problem to be solved by the invention]

[0005] As in the conventional technology disclosed in Patent Document 4, by forming unevenness on the surface of a resin component for a vehicle by embossing or the like, it is possible to obtain a design effect that enhances visual appeal and an effect that improves functionality, such as optimizing frictional force.

[0006] However, in the conventional resin member for vehicles, it is difficult to remove dirt such as dust that adheres to the recesses formed on the surface, and the recesses are not easy to clean. Specifically, for example, as shown in Fig. 6, when a recess 111 is formed on a surface 110a of a sheet member 102 for vehicle interior, which is a resin member for vehicles made of synthetic resin, by embossing, dirt 30 such as dust tends to gather and adhere inside the recess 111.

[0007] The dirt 30 adhering to the inside of the recess 111 is difficult to remove, for example, by wiping the surface 110a of the vehicle interior sheet member 102 with a cleaning tool 31 such as a towel or a mop. The dirt 30 that is not removed and remains inside the recess 111 not only mars the aesthetic appearance of the vehicle interior sheet member 102, but also adheres to the inside of the recess 111, making it even more difficult to remove.

[0008] Furthermore, in the prior art resin member for a vehicle, if the surface is scratched with a hard, sharp object, the scratch is easily noticeable and the aesthetic appearance of the vehicle is marred. That is, as shown in Fig. 6, the surface 110a of the prior art vehicle interior sheet member 102 has a wide flat surface, so scratches are easily noticeable.

[0009] The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a resin member for vehicles, a sheet member for vehicle interiors, and a board for vehicle interiors using the same, which is easy to remove dirt such as dust adhering to the surface, provides an excellent three-dimensional aesthetic appearance on the surface, and even if the surface is scratched, the scratches are not noticeable and a beautiful appearance is maintained. [Means for solving the problem]

[0010] The vehicle resin member of the present invention is characterized in that a plurality of recesses are formed on the surface, the maximum depth of the recesses is smaller than the distance from the center to the edge of the bottom surface of the recesses, and the bottom surface is raised outward at the center such that the depth of the center is shallower than the depth of the edge.

[0011] The vehicle interior sheet member of the present invention includes the vehicle resin member, and a sheet layer having the surface is formed by the vehicle resin member.

[0012] The vehicle interior board of the present invention is characterized in that the vehicle interior sheet member is used as a surface member. Effect of the Invention

[0013] According to the vehicle resin member of the present invention, a plurality of recesses are formed on the surface, and the maximum value of the depth of the recesses is smaller than the distance from the center to the edge of the bottom surface of the recesses, and the center of the bottom surface is raised outward so that the depth of the center is shallower than the depth of the edge. With this configuration, the wiping portion of a cleaning tool such as a towel, mop, or brush can reach the bottom surface of the recesses, and dirt such as dust attached to the surface of the vehicle resin member can be easily wiped off and removed. In addition, the vehicle resin member can obtain an excellent three-dimensional aesthetic appearance by reflection of light irradiated on the approximately flat reference surface, the shallow steps at the edges of the plurality of recesses formed, and the bottom surface formed to be raised outward. In addition, since the bottom surface of the vehicle resin member is not flat but has a raised center, even if scratches are formed on the surface of the vehicle resin member, the scratches are not noticeable and the aesthetic appearance of the surface is not impaired.

[0014] In addition, in the vehicle resin member of the present invention, the recesses may be formed in a regular hexagonal shape in a plan view and arranged in a honeycomb lattice pattern. With such a configuration, dirt and the like that has adhered to the vicinity of the corners of the bottom surface of the recesses can be easily removed, and excellent dirt removal performance can be obtained. In addition, the recesses that are arranged in a honeycomb lattice pattern and have a raised center portion of the bottom surface can form a beautiful surface with a three-dimensional effect. Furthermore, even if the surface is scratched, the scratch is not easily noticeable.

[0015] In addition, the bottom surface of the vehicle resin member of the present invention may be formed in the shape of a sloping surface of a regular hexagonal prism or the top surface and sloping surface of a regular hexagonal truncated pyramid. With this configuration, even if the recess is shallow, a beautiful three-dimensional effect can be obtained, and excellent removal performance that allows dirt such as dust to be easily wiped off can be obtained. In addition, such a bottom shape of the recess provides an excellent aesthetic appearance by making good use of light reflection. Furthermore, even if the surface is scratched, the scratch is not noticeable.

[0016] In the vehicle resin member of the present invention, the distance between adjacent recesses is smaller than the distance from the center to the edge. With this configuration, a vehicle resin member can be obtained that has a beautifully designed surface that is less susceptible to scratches, has excellent dirt removal properties, and exhibits excellent performance as a surface member for vehicle exteriors, floor panels, etc.

[0017] The vehicle interior sheet member of the present invention includes the vehicle resin member, and a sheet layer having the surface is formed by the vehicle resin member. With this configuration, a vehicle interior sheet member having a beautifully designed surface, excellent dirt removal properties, and surface scratches that are less noticeable can be obtained. The vehicle interior sheet member can also exhibit favorable frictional properties and favorable cushioning properties as a surface member for automobile seats, luggage compartment floor panels, etc.

[0018] The vehicle interior board of the present invention uses the vehicle interior sheet member as a surface member. With this configuration, a vehicle interior board can be obtained that has a three-dimensional, beautiful surface that is less susceptible to scratches, has excellent dirt removal properties, and exhibits excellent performance as a vehicle floor panel, etc., in terms of cushioning properties, friction properties, strength, abrasion resistance, etc. [Brief description of the drawings]

[Figure 6] 1A and 1B are diagrams showing an example of cleaning a vehicle interior seat member according to the prior art; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, a vehicle interior board 1 and a vehicle interior sheet member 2 will be described in detail with reference to the drawings as an example of a vehicle resin member according to an embodiment of the present invention.

[0021] 1 is a perspective view showing a schematic configuration of a vehicle interior board 1 as a vehicle resin member according to an embodiment of the present invention. The vehicle interior board 1 is used, for example, as a floor board for the trunk of a vehicle such as an automobile, i.e., a deck board or a luggage board, or as a back board for a seat, etc.

[0022] The vehicle resin member according to the embodiment of the present invention may be used as an exterior member of a vehicle such as an automobile, etc. For example, the vehicle resin member according to the embodiment of the present invention may be used as a fender resin molding provided on a tire of an automobile, etc., a side sill provided under a door, etc., a bumper provided at the front and rear of a vehicle body, or other members constituting an outer resin portion of a vehicle.

[0023] As shown in Fig. 1, the vehicle interior board 1 is an integrally molded multi-layered plate-like body. The vehicle interior board 1 includes a pair of metal plates 20 and 21, a polyurethane foam layer 22 formed between the metal plates 20 and 21, and a vehicle interior sheet member 2 provided on the outer surface of the metal plate 20. The vehicle interior board 1 is molded into a predetermined peripheral shape according to the application.

[0024] The metal plate 20 is provided on a surface that faces the inside of the vehicle interior when the vehicle interior board 1 is attached to the vehicle. On the other hand, the metal plate 21 is provided on a surface that faces the outside of the vehicle when the vehicle interior board 1 is attached to the vehicle. Specifically, when the vehicle interior board 1 is used as a floor panel of the vehicle, the metal plate 20 is provided on the upper part of the vehicle interior board 1 and faces upward toward the inside of the vehicle interior, and the metal plate 21 is provided on the lower part and faces downward toward the outside of the vehicle.

[0025] The vehicle interior sheet member 2 is a skin material provided on the outer surface of a metal plate 20, i.e., the surface facing the interior of a vehicle compartment, and covers the metal plate 20. A plurality of recesses 11 are formed by embossing or the like on the surface of the vehicle interior sheet member 2, i.e., the surface of the vehicle interior board 1 facing the interior of the vehicle compartment. Details will be described later.

[0026] Although not shown in the drawings, a skin material (not shown) for surface finishing may be provided depending on the application on the outer surface of the metal plate 21, i.e., the surface facing the vehicle exterior of the vehicle interior board 1. As the skin material, for example, a woven fabric, a nonwoven fabric, or various other sheet materials made of synthetic resin such as polyethylene terephthalate (PET) or other fibers may be used.

[0027] Although not shown, a protruding rib portion protruding toward the outside of the vehicle may be formed on the metal plate 21. By forming the protruding rib portion, the strength and rigidity of the vehicle interior board 1 can be increased.

[0028] Furthermore, the vehicle interior board 1 may be formed with mounting holes, handle holes, etc. (not shown) for attaching other parts such as hinges, screws, rivets, handles, etc. (not shown) to the vehicle interior board 1. Furthermore, the vehicle interior board 1 may be provided with other reinforcing members or fastening members such as grommets, steel wires, etc. (not shown).

[0029] Fig. 2 is an enlarged cross-sectional view showing a schematic configuration of vehicle interior board 1. Referring to Fig. 2, vehicle interior board 1 has a thickness of, for example, about 3 to 20 mm.

[0030] The pair of metal plates 20, 21 are substantially flat plate members, such as aluminum plates. The thickness of the metal plates 20, 21 is, for example, about 0.1 to 0.3 mm, preferably about 0.12 to 0.15 mm. By using aluminum plates as the metal plates 20, 21, the vehicle interior board 1 can be made lightweight and strong.

[0031] Other metal plates, such as galvanized steel plates and various painted steel plates, may be used as the metal plates 20 and 21. When steel plates are used as the metal plates 20 and 21, the thickness of the metal plates 20 and 21 is preferably about 0.07 to 0.3 mm.

[0032] Fig. 3 is an enlarged cross-sectional view showing a schematic configuration of the vehicle interior sheet member 2. Referring to Fig. 3, the vehicle interior sheet member 2 has a synthetic resin sheet layer 10 made of a thermoplastic plastic material such as polyvinyl chloride (PVC). The sheet layer 10 forms the surface of the vehicle interior sheet member 2, i.e., the surface facing the vehicle interior.

[0033] The thickness of the sheet layer 10 constituting the surface of the vehicle interior sheet member 2 is, for example, about 0.2 to 3 mm, preferably about 0.3 to 1.5 mm, and more preferably about 0.3 to 1.3 mm. This allows the sheet layer 10 of the vehicle interior sheet member 2 to cover the outer surface of a vehicle interior board 1 (see FIG. 1) used as a floor panel of a luggage compartment of an automobile or the like, and to have suitable performance as the surface of a sheet member on which luggage or the like is placed.

[0034] A fiber layer 17 may be provided on the back surface of the sheet layer 10, i.e., the surface that is bonded to the outer surface of the metal plate 20 (see FIG. 1) of the vehicle interior board 1. As the fiber layer 17, for example, a woven fabric, a nonwoven fabric, or various other sheet materials made of synthetic resin such as polyethylene terephthalate or other fibers may be used.

[0035] The thickness of the fiber layer 17 is, for example, about 0.5 to 10 mm, and preferably about 0.5 to 1 mm. By providing such a fiber layer 17, the vehicle interior sheet member 2 can obtain suitable performance as a skin material that covers the outer surface of the vehicle interior board 1 used as a floor panel of a luggage compartment of an automobile or the like and on which luggage or the like is placed.

[0036] Fig. 4 is an enlarged plan view showing a schematic configuration of the vehicle interior sheet member 2. With reference to Figs. 3 and 4, the vehicle interior sheet member 2 has a plurality of recesses 11 formed on the surface of a sheet layer 10 made of synthetic resin.

[0037] The recesses 11 are formed in a generally regular hexagonal shape in plan view and are arranged in a honeycomb lattice pattern. The size of the recesses 11 is, for example, such that the side-to-side distance, i.e., the distance L2 which is the minimum horizontal distance from the center 14 to the edge 15, is about 1 to 5 mm, preferably about 1.4 to 3 mm, and more preferably about 1.8 to 2.6 mm.

[0038] By forming the recess 11 in this form, the interior angle of the recess 11, i.e., the angle of the corner of the bottom surface 12, is approximately 120 degrees, making it easier to remove dirt 30 (see Figure 5) such as dust that has adhered near the corner of the bottom surface 12, resulting in excellent dirt removal performance.

[0039] The bottom surface 12 of the recess 11 may be formed in a substantially triangular shape, a rectangular shape, another polygonal shape, a circular shape, an elliptical shape, or any other shape when viewed from above.

[0040] In addition, the bottom surface 12 of the recess 11 is formed so that the central portion 14 rises outward, i.e., toward the cabin side of the automobile, etc. Specifically, the bottom surface 12 is formed so that the depth of the central portion 14 is shallower than the depth L1 in the vicinity of the edge portion 15.

[0041] For example, the depth L1 near the edge 15, which is the maximum value of the depth of the recess 11, is about 0.1 to 1 mm, preferably about 0.3 to 0.7 mm, and more preferably about 0.4 to 0.6 mm. The central portion 14 may be formed at approximately the same height as the reference surface 10a of the sheet layer 10, i.e., the surface on which the recesses 11 are not formed.

[0042] This configuration in which the central portion 14 of the bottom surface 12 rises outward makes it easier to remove dirt 30 such as dust from the vicinity of the edge portion 15 of the recessed portion 11. In addition, the recessed portions 11 arranged in a honeycomb lattice pattern and with the central portion 14 of the bottom surface 12 raised can form a beautiful surface with a three-dimensional effect. Furthermore, scratches on the surface are not noticeable. Furthermore, the vehicle interior sheet member 2 can exhibit favorable frictional performance and favorable cushioning performance as a surface member for the seats of automobiles, floor panels of luggage compartments, etc.

[0043] In detail, the bottom surface 12 of the recess 11 may be formed in the shape of a regular hexagonal inclined surface. That is, six substantially triangular inclined surfaces 13 may be formed with the central portion 14 of the bottom surface 12 as the apex of the regular hexagon. The bottom surface 12 may also be formed in the shape of the upper surface and inclined surfaces of a regular hexagonal pyramid. That is, the central portion 14 may be formed in a substantially flat substantially hexagonal shape like the upper surface of a regular hexagonal pyramid, and the inclined surfaces 13 may each be formed in a substantially trapezoidal shape. The inclined surfaces 13 of the bottom surface 12 may also be formed in a curved shape.

[0044] With this configuration, even if the recess 11 is shallow, a beautiful three-dimensional effect is obtained, and excellent removal performance is obtained, allowing dirt 30 such as dust to be easily wiped off. In addition, such a shape of the bottom surface 12 provides an excellent aesthetic appearance by making optimal use of light reflection. In addition, scratches on the surface are not noticeable.

[0045] Furthermore, the distance L3 between adjacent recesses 11, i.e., the width dimension of a protrusion 16 where no recesses 11 are formed, is smaller than the distance L2 which is the minimum horizontal distance from the center 14 to the edge 15. Specifically, the distance L3 which is the width dimension of the protrusion 16 is, for example, about 0.2 to 3 mm, preferably about 0.3 to 0.8 mm, and more preferably about 0.4 to 0.7 mm.

[0046] With this configuration, a sheet member 2 for vehicle interiors can be obtained that has a beautifully designed surface that does not show scratches, has excellent dirt removal properties, and exhibits excellent performance as a surface member for vehicle floor panels, etc. The corners of the upper surface of the protrusions 16, i.e., the corners of the surface that constitutes the reference surface 10a, may be subjected to R-chamfering to form a curved surface.

[0047] Fig. 5 is a diagram showing an example of cleaning the vehicle interior sheet member 2. As shown in Fig. 5, when the surface of the vehicle interior sheet member 2 is cleaned using a cleaning tool 31 such as a towel, mop, or brush, the wiping portion of the cleaning tool 31 reaches substantially the entire bottom surface 12 of the recess 11. Thus, dirt 30 such as dust adhering to the surface of the vehicle interior sheet member 2 can be easily wiped off and removed without remaining on the bottom surface 12.

[0048] In addition, since the bottom surface 12 of the recess 11 of the vehicle interior sheet member 2 is inclined, even if the surface is scratched by a sharp object, the scratches are not noticeable. In other words, even if the surface of the vehicle interior sheet member 2 is scratched by dragging when loading and unloading heavy luggage or by scratches by the claws of pets, the aesthetic appearance of the surface is not marred by the scratches, and the three-dimensional beautiful surface design can be maintained.

[0049] As described above, the vehicle interior board 1 according to this embodiment (see FIG. 1) is provided with a vehicle interior sheet member 2 having a surface on which a plurality of recesses 11 are formed in a suitable configuration. Therefore, the vehicle interior board 1 has a beautiful surface with a three-dimensional appearance that does not stand out when scratched, is excellent in dust removal properties, and exhibits excellent performance as a vehicle floor panel, etc., such as cushioning performance, friction performance, strength, and abrasion resistance.

[0050] The present invention is not limited to the above embodiment. The vehicle resin member of the present invention having a suitable uneven surface can be used in various forms as a resin member constituting various exterior or interior members of automobiles, etc. The present invention can be modified in various ways without departing from the scope of the present invention.
