Description

The present invention relates to an instrument panel, has a good appearance, and an instrument panel suitable for preventing a trouble in driving because the surface form of the instrument panel is very rarely reflected on the windshield surface of an automobile. The ment panel.

  An instrument panel of an automobile is desired to have a tactile feeling and a good appearance as viewed from a driver or the like, and to exhibit a so-called high-class feeling, and therefore various devices are applied. On the other hand, from the driver's side, when the shape of the substantially horizontal surface portion located on the windshield side of the instrument panel is reflected on the windshield surface, it becomes difficult for the driver to clearly recognize the front scenery from the driver's seat, May interfere with driving.

  In order to eliminate such harmful effects, it is desired to improve the instrument panel. Conventionally, it has been reported that the surface of the instrument panel is matted from the surface that prevents the shape of the substantially horizontal surface portion located on the windshield surface side from being reflected on the windshield surface. (Japanese Patent Laid-Open No. 2006-282052)

  However, when the surface of the instrument panel is matted, it is possible to prevent the shape of the substantially horizontal surface portion of the instrument panel located on the windshield surface side from being reflected on the windshield surface. It has good tactile sensation and appearance, and cannot exhibit a so-called high-class feeling.

JP 2006-282052 A

  The object of the present invention is to solve the above-mentioned problems, have a good appearance, and that the surface form of the instrument panel is very unlikely to be reflected on the windshield surface of the automobile, so that it does not hinder driving. It is to provide an instrument panel that can be used.

The present invention has the following configuration in order to solve the above-described problems.
That is, the instrument panel of the present invention has the following configuration.
<1> Of the substantially horizontal plane portion of the upper surface of the instrument panel, at least half of the area surface from the windshield surface side is formed on the pattern stop, and at least a part of the convex surface of the pattern stop has a protrusion. The instrument panel is characterized in that the protrusion of one region including the convex surface and the protrusion in a region different from the region indicate different directions.
<2> A pattern in which the connection region portion between the substantially horizontal surface portion on the upper surface of the instrument panel and the substantially inclined portion located on the driver seat side of the instrument panel gradually changes from the substantially horizontal surface portion to the substantially inclined portion. It is an instrument panel as described in said <1> which consists of a change area | region surface.
<3> The area surface of the substantially horizontal plane portion on the upper surface of the instrument panel is formed in a pattern-shaped diaphragm, and the pattern-shaped diaphragm has a large number of columnar sections having an arbitrary cross section, and the upper surface of the columnar section has a protruding shape. <1> or <2>, wherein the protrusion formed on the upper surface of the columnar part in one region and the protrusion formed on the upper surface of the columnar part in another region indicate different directions. This is an instrument panel.
<4> The area surface of the substantially horizontal plane portion on the upper surface of the instrument panel has a large number of columnar portions having an arbitrary cross section, and a protrusion is formed on the upper surface of the columnar portion. <2> The connection region portion between the horizontal surface portion and the substantially inclined portion located on the driver's seat side of the instrument panel is gradually reduced in height from the substantially horizontal surface portion to the substantially inclined portion. This is an instrument panel.
<5> The instrument according to <4>, wherein in the connection region portion, the height of the protrusion gradually decreases from the substantially horizontal surface portion to the approximately inclined portion, and the skinning pattern is deep. It is a panel.

  According to the present invention, at least a half of the area surface from the front glass surface side of the substantially horizontal plane portion of the upper surface of the instrument panel is formed on the pattern diaphragm, and at least a part of the convex surface of the pattern diaphragm Since a protrusion is formed, and the protrusion of one region including the convex surface and the protrusion in a region different from the region indicate different directions, the substantially horizontal surface portion of the instrument panel diffuses and reflects light. The surface form of the substantially horizontal surface portion of the instrument panel is hardly reflected on the front glass surface. Therefore, there is no trouble in driving. Moreover, since the substantially horizontal plane part of the instrument panel is formed with a pattern stop, the substantially horizontal plane part of the instrument panel can maintain a good-looking state.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an arrangement state of an instrument panel in an automobile, and FIG. 2 shows a drawing formation region of an instrument panel portion on a sheet before convex vacuum forming.
In the figure, the instrument panel surface is an area closest to the windshield 16 of the instrument panel and is substantially horizontal plane portion 10 and substantially inclined portion 14 that is inclined with respect to the substantially horizontal plane portion 10 on the driver side. The connection portion 12 is located between the substantially horizontal plane portion 10 and the substantially inclined portion 14.

  Although the surface form of the substantially horizontal surface portion 10 is the region most easily reflected on the windshield 16, in the present embodiment, the substantially horizontal surface portion 10 has a structure shown in FIG. FIG. 3A shows a part of the substantially horizontal surface portion 10 in an enlarged manner. The surface of the approximately horizontal surface portion 10 has a large number of circular columnar portions 18 formed on each circular surface. As shown in FIG. 3B, a plurality of protrusions 20 are provided. The formation direction of the protrusions is constant in one region and is different from the formation direction in the other regions. In order to diffusely reflect, it is preferable that one region is as small as possible.

  In FIG. 3A, in the triangular region where the group of circular columnar portions 18 is formed, the protrusion 20 shows a certain direction, and in other regions other than this triangular region, the direction of the protrusion 22 is Shows any direction. The region where the protrusion 20 indicates a certain direction is not limited to a triangular region, and may be a square region, other polygonal regions, or the like.

  The substantially inclined portion 14 has a skin-squeezing pattern as a diaphragm having good tactile sensation and good appearance, and the connecting portion 12 is a change area region between the substantially horizontal surface portion 10 and the substantially inclined portion 14. As used herein, the change area region means an area surface on which a pattern in which the pattern of the inclined portion 14 is gradually changed from the pattern of the approximately horizontal surface portion 10 is formed. The overall appearance of the instrument panel is excellent.

As the gradually changing region surface, the surface of the substantially horizontal surface portion 10 has a large number of columnar shapes 18 having an arbitrary horizontal cross section, and a protrusion 20 is formed on the upper surface of the columnar shape 18. The connecting portion 12 is preferably such that the height of the protruding portion 20 and / or the columnar portion 18 such as a large number of circular shapes gradually decreases from the substantially horizontal plane portion 10 to the substantially inclined portion 14. Moreover, it is preferable that the connection part 12 of the substantially horizontal plane part 10 and the substantially inclined part 14 is provided shallowly from the substantially inclined part 14 toward the substantially horizontal part.
It can also be.

  In the instrument panel according to the above-described embodiment, the substantially horizontal surface portion 10 is formed with a pattern in which a large number of circular shapes are formed, looks good, and the direction in which the protrusions 20 are formed is a predetermined region. Is constant, and in other regions, the direction is different from the direction in which the formation is performed and is in an arbitrary direction, so that light incident on the substantially horizontal surface portion 10 is irregularly reflected. As a result, the surface shape of the instrument panel is not directly reflected on the windshield. Therefore, the driver can clearly recognize the scenery in front from the driver's seat, and does not hinder driving.

  In the present invention, the substantially horizontal plane portion 10 is not limited to a pattern having a large number of planar cross-sections, but can have any shape. For example, columnar sections having a triangular cross section, a quadrilateral shape, other polygonal shapes, an elliptical shape, or any other figure shape can be adopted, and protrusions are formed on the surfaces of these columnar portions. Any shape can be selected in terms of the appearance of the pattern.

  Further, in the present invention, instead of the plurality of linear protrusions 20 in which a large number of planar cross sections are formed on a circular shape surface, the planar cross section has a shape capable of irregular reflection on the convex surface portion other than the circular shape. Can be adopted. That is, instead of a plurality of linear protrusions, a protrusion having an arbitrary shape such as a “<” shape, an arc, or a curve can be employed. In the case of these protrusions, it is desirable to have a portion in which the directionality of most of the protrusions in one region is different from the directionality of most of the protrusions in the other region.

  The substantially horizontal plane part 10 desirably has the above-described surface form as a whole, but does not necessarily have to have the above-described surface form. At least half of the substantially horizontal plane part 10 from the windshield side has the above-described surface form. More preferably, it is preferable that at least 2/3 or more of the substantially horizontal surface portion 10 from the front glass surface side, more preferably, the entire surface of the approximately horizontal surface portion 10 has the above-described surface form.

  The standard value of the gross value of the instrument panel itself is 1.3 to 1.6 as the upper limit, but the instrument panel of the present invention has a gross value while the substantially horizontal plane portion 10 maintains the above-described surface form. Is 60 or less, preferably 0.7 or less, and 85 ° is 1.5 or less, preferably 1, 2 or less.

  The instrument panel of the present invention can be produced by a roll embossing method or a flat embossing method. In the roll embossing method, for example, a substantially horizontal plane portion, a substantially inclined portion, and a connection region portion are engraved in predetermined shapes, respectively, and are continuously formed on a synthetic resin sheet having a width of 1200 mm with an embossing roll having a diameter of 700 mm and a length of 1680 mm. After squeezing and pressing, each can be cut to a length of 2000 mm, and then manufactured by convex vacuum forming.

  In the flat embossing method, for example, a substantially horizontal surface portion, a substantially inclined portion, and a connection region portion are squeezed onto a synthetic resin sheet having a length of 1200 mm and a width of 2000 mm using a squeezed plate, and then a convex shape. It can be manufactured by vacuum forming. The flat embossing method is suitable for more faithfully expressing the surface form of the substantially horizontal surface portion.
